Objective Bitter gourd (Momordica charantia L.) is a widely consumed vegetable. This study aimed to assess the impact of spiritual blessing (biofield) energy treatment (S/BET) known as the Trivedi Effect® on a plant’s growth and yield when applied to both seeds and soil. Methods Seeds were split into two groups: an untreated control group (CONBIGG) and a BET-group (BTBIGG). Soil texture was checked by hand, and mineral contents were measured using standard procedures. An experienced scholar noted plant morphological, phenological, and yield-related parameters. Results The S/BET group showed improvements in stem length, fruit colour, and seediness compared to the control. Other phenological parameters, such as vine length (38.78 %; p ≤ 0.001), branch number (54.03 %; p ≤ 0.01), inter-nodal length (42.94 %; p ≤ 0.001), fruit length (33.27 %; p ≤ 0.001), seed length (40.32 %; p ≤ 0.001), seeds per fruit (52.50 %; p ≤ 0.001), and fruits per vine (66.88 %; p ≤ 0.001), were significantly increased in the BTBIGG group compared to the CONBIGG. Yield per hectare rose by 61.31 % in the S/BET group compared to the control. Conclusion The study results suggest that the spiritual blessing/prayers/BET-Trivedi Effect® significantly improved morphological, phenological, and yield-related parameters compared to the control group. This study provides useful scientific research data and information for producing stable, high-quality bitter gourds.

Background Tick infestations severely impair cattle health and productivity in Nigeria through blood loss, hide damage, and transmission of tick-borne pathogens. Objective This study assessed key risk factors influencing tick infestation and evaluated control methods among Fulani pastoral herds in Plateau State. Methods A cross-sectional survey involving 250 cattle from ten herds was conducted across five Local Government Areas. Tick burden was analyzed against acaricide application methods (pour-on vs. hand-spray), hand-picking frequency, and herd mobility (sedentary vs. migratory). Data were collected via owner interviews and manual tick counts. Statistical analyses were performed using generalized linear models in R software. Results Cattle treated with pour-on acaricides had significantly lower tick burdens compared to those treated via hand-spray (P<0.05). Herds that practiced hand-picking five times weekly had fewer ticks than those hand-picking thrice weekly (P<0.01). Migratory herds recorded significantly lower infestations than sedentary herds (P<0.05). Conclusion Effective tick control requires the integration of optimized acaricide application, frequent manual removaland consideration of herd mobility patterns. Education, capacity building, and policy support are necessary to enhance adoption of effective tick control measures among pastoralists.

Background Immunoglobulins are bio-receptors found embedded in the cell membrane with a biological role that detects the harmful molecules of a test compound. These bio-receptors interface between a biological system and its external environment that transduce information to the effector via intermediate messengers in which its response efficiency usually exhausts at high doses of exposure to external stimuli. The purpose of this review article is, therefore, to elaborate on the computational method for systemic biology which was designed to convert qualitative pharmacological data into the quantitative one that might help to determine the toxicity of a test compound. Methods First, acute toxicity studies using different levels of doses prepared from each test compound have been conducted on Balb c mice. Then, blood specimens from the tail and facial veins of each sampled Balb c mouse were collected 3 days before dosing as a reference test and 4 hr after dosing for comparison. The changes in the efficiency of immunoglobulins immune response (ΔIg) after dosing were determined using quantitative immunoassay and the body’s response against the dose as the toxic reaction rate (r) and the toxic severity (s) were finally determined using computational methods as r=d/t-ΔIg mg/sec and (s=r/w×100) %/sec respectively, where (w) represents the body weight of a study animal, (t) represents the period of time at which undesirable bio-physiological responses manifested on treated study animals and (ΔIg) represents the changes in the concentration of immunoglobulins in blood serum after dosing. Results The results of different studies revealed that the dose has never limited the toxic property of a test compound but the length of time at which the undesirable side effect was manifested on study animals. The period of time at which adverse effects manifested on treated Balb c mice was inversely related to the amount of dose administered in the oral route. The higher the dose of the administered test compound, the shorter the period of time at which the undesirable side effect was manifested on treated Balb c mice. This means that the adverse effect of test compounds was not because of the dose but rather due to its toxic reaction rate which ultimately determined the toxic severity in the natural process of treated Balb c mice. Balb c mice treated with a dose whose toxic reaction rate was ≤ 0 survived from death whereas Balb c mice treated with a dose that had a toxic reaction rate of > 0 died at different lengths of time after dosing depending on the toxic severity of a test compound. It could be a scientific fact to declare that a test compound is safe when the toxic reaction rate (r) and toxic severity (s) of a dose is ≤ 0 and toxic when it is > 0 in the natural processes of a study animal.

Small island states, such as Malta face numerous, unique challenges in relation to agricultural sustainability, with solutions amenable to larger states being unfit given the particular characteristics of the island. These include the poor soil conditions, the limited water resources, the aging farmer population, farming being mainly part-time, and most farmers having no formal training. Currently farmers practice intensive agriculture to achieve higher crop productivity at lower production costs by relying heavily on agri-chemicals and over-extracting groundwater. This destroys the Maltese natural environment and urges for the development and implementation of sustainable agriculture practices, whereby traditional farming is supplemented with sustainable alternatives such that local agriculture remains productive in the long-term while safeguarding the local environment. Here we outline some of the critical issues that urgently need to be addressed and potential ways forward in relation to soil, water and biodiversity, implementing permaculture principles in small-scale, practical actions in order to improve the sustainability of local agricultural through a combination of scientific evidence, agricultural technology and traditional practices.

Isolation methods that employ readily-available inexpensive supplies on the open market, which are reliable, as well as economical, such as nucleic acid amplification techniques (NAAT) based on microfluidic technology in low-resource research settings (LRRS) that meets the ASSURED guidelines are essential to develop a noninvasive diagnostic colon cancer screen in stool using micro(mi)RNA molecules. A combination of a microfluidic-based MiRNA stool test with a reliable rolling circle amplification/detection method applied to the quantification of miRNA molecules, result in an affordable sensitive and specific isothermal method for the noninvasive quantitative detection of miRNAs in LRRS. Scientists and engineers have become interested in miRNAs, and they have intensified their efforts to apply emerging simple detection tools to the important bioanalytical challenge of quantifying these small 18-26 nt long molecules. Some of the proposed approaches incorporate novel material, such as simple centrifuges and methods based on microfluidic technology, while others utilize the interesting biological properties of these molecules, such as forming branched RCA structures, allowing for the detection of these biomarker molecules at an attomolar "aM" concentration level, using low cost extraction and isothermal amplification methods in LRRS. We have been interested in studying colorectal cancer (CRC) because it is the 3rd most common malignancy worldwide, and stool can be obtained noninvasively from the patients. We have focused in this research on colon cancer (CC) because it is more common in the USA than rectal cancer (RC). The innovation of our approach lies in the exploratory use of an affordable, quantitative miRNA profiling in noninvasive stool samples in LRRS, whose extracted fragile total RNA is stabilized shortly after excretion from stool by commercially available kits, so it does not ever fragment, followed by quantitative standardized analytical tests that are neither labor intensive, nor require expensive instrumentation, in order to develop apanel of novel miRNA genes for the noninvasive diagnostic screening of early left and right sporadic colon cancers, more economically, and with higher sensitivity and specificity than any other colon cancer screening test currently available on the market. To show the clinical sensitivity and specificity of the proposed quantitative miRNA test using simple methodologies in LRRS,the miRNA results are to be correlated with FOBT, colonoscopy, and pathology data. Standardization establishes test’s performance criteria (sample selection, optimal sample running conditions, preservation and storage), in order to ensure that the assay will perform the same way in any laboratory, by any trained personnel, anywhere in low-resource laboratory settings worldwide.

Pyruvate holds superior biomedical properties in increase of hypoxia tolerance, correction of severe acidosis, exertion of anti-oxidative stress and protection of mitochondria against apoptosis, so that it improves multi-organ function in various pathogenic insults. Particularly, pyruvate preserves key enzyme: pyruvate dehydrogenase (PDH) activity through direct inhibition of pyruvate dehydrogenase kinas (PDK), as a PDH activator, in hypoxia. Therefore, pyruvate is robustly beneficial for cell/organ function over citrate, acetate, lactate, bicarbonate and chloride as anions in current medical fluids. Pyruvate-enriched oral rehydration salt/solution (Pyr-ORS) and pyruvate-based intravenous (IV) fluids would be more beneficial than WHO-ORS and current IV fluids in both crystalloids and colloids, respectively. Pyruvate-containing fluids as the new generation would be not only a volume expander, but also a therapeutic agent simultaneously in fluid resuscitation in critical care patients. Pyruvate may be also beneficial in prevent and treatment of diabetes, aging and even cancer. Pyruvate clinical applications indicates a new revolutionary medical advance, following the WHO-ORS prevalence, this century.

Currently, enhanced oil recovery (EOR) acquire increased attention to recover more residual oil trapped after the primary and secondary process in petroleum reservoirs. EOR comprise different technologies involving chemical, thermal, miscible flooding techniques. Chemical flooding by the polymer is a widely implemented method on the academic and industrial scale. In this chapter, the authors discuss polymer flooding using polyacrylates that involve hydrolyzed polyacrylamide (HPAM), hydrophobically associated polyacrylamides (HAPAM), which grafted with different vinyl monomers such as acrylic acid, methyl methacrylates, and 2-acrylamido-2-methylpropane sulfonic acid (AMPS). These polymers increase the viscosity of injected brine solutions, as a result, decrease mobility ratio and enhance sweeping efficiency, so the water act as a piston, which pushes oil in front of it, and consequently increase the recovery factor. The advantages and disadvantages of these polymers as well as comparing different flooding scenarios are reported.

p-hydroxybenzoic acid esters are used as food and drug preservatives. These compounds were quantised by a reversed-phase thin-layer chromatography method based on the use of silanized silica gel as stationary phase. Thin layers chromatography of silanized silica gel (HF254) is implemented to separate p-hydroxybenzoic acid and its methyl, ethyl, propyl, butyl and benzyl esters. Borate buffer (pH 2) was used as a mobile phase with the addition of organic solvent as required. For the quantitative determination, the solutions to be analysed were applied in bands on 5 x 20 cm plates. The plates are developed in glass chromatography chambers lined with filter paper. After the plates have been developed they are dried at room temperature. The spots or bands of the various compounds are visualised under a 250-mµ UV light source. The extraction of the silica gel with methanol was effective. Six preservatives were separated with better results for benzyl- and butyl-p-hydroxybenzoates. Chromatographic development controlled by temperature stability in the chromatographic chamber and spectrophotometric determination of all the compounds were indicated. A second development with the same solvent mixture was suggested especially when low RF is involved. Various compounds are completely separated and a good determination of p-hydroxybenzoic acid and its principle esters are possible using a simple technique of elution and spectrophotometric determination.

Fingerprint is an impression made by the friction ridges that are almost parallel at constant crest to crest wavelength. The pattern is dominated by central features, such as whorls, loops, arches and triradii. Fingerprints have been used for several decades in forensic and medical sciences. The fingerprints characteristics such uniqueness, consistency and universality are the main features that are used by forensic experts in identification processes, are well developed during intra-uterine life. Understanding embryogenesis of fingerprints is essential in linking its features to some disease conditions. The purpose of this review was to highlight information regarding establishment, formation, hypotheses and factors affecting fingerprints. Applications of the fingerprints in forensic and medical sciences were also highlighted. Both environmental (in utero) and genetic factors have role to play in the formation of the fingerprints. The primary role of fingerprints is personal identification; these can be achieved through revealing sex, ethnicity, diet and lifestyle of an individual. In another perspective the fingerprints can be used as tools in diagnosis and ascertaining presence of disease conditions, however, this is population specific.

Enteroatmospheric fistula is a challenging and emerging clinical situation, mainly related to “open abdomen” technique in damage control surgery for trauma and in case of multiple laparotomies. We report the case of a 61-year-old male patient, affected by rectal carcinoma, submitted to standard surgical treatment and gradually evolving in persistent proximal jejunal fistula. The positioning of a cardiac septal occluder (Amplatzer®) was associated with immediate and late favourable effects. The procedure was conducted “bed-side” and turned out to be easy and safe.

A hybrid monolithic column was prepared using octavinyloctasilasesquioxane (OVS) as a monomer, benzoyl peroxide/dimethylacetamide (BPO/DMA) as initiator, ethylene glycol dimethacrylate (EDMA) as cross-linker, 1-dodecanol as porogenic agent and dimethylbenzene as cosolvent. A tidy skeleton, much bigger specific surface area (22.4 m2/g) and lower swelling property of the monolithic column with OVS added than the one without OVS added were determined with Scanning Electron Microscopy (SEM), Nitrogen adsorption/desorption measurements (BET) and swelling test with elute of different concentration of acetonitrile in water. Fourier-transform infrared spectra (FTIR) was taken to characterize the composition of groups. Moreover, a better separation performance for benzene series compounds under reversed phase liquid chromatography (RPLC) mode was obtained using the monolithic columns with OVS added than those without.

Since a few years, more and more attention has been specifically given to dietary antioxidants as agents promoting health and preventing the incidence of diseases. As part of these efforts, analytical methods and assays have been developed to measure the antioxidant content in food substances. In this paper, the antioxidant capacity of 17 orange juices is determined by various assays (DPPH, ORAC, heamolysis, xanthine/xanthine oxidase) as the content in ascorbic acid and total phenolics. The results evidence all the complexity to evaluate the in vitro antioxidant capacity of foods. In very general terms, in spite of the wide utilization in these tests (FRAP, TAC, ORAC TRAP and others), their significance remains obscure. The discrepancy of the results and the absence of good correlation between the assays clearly highlight all the importance of understanding the strengths and weakness of assays evaluating antioxidant potential of a food at the risk of giving erroneous information to the consumer. It is clear that the use of "total antioxidant capacity" assays for the in vitro assessment of antioxidant quality of food does not be employed by food industrials as a marketing argument or for the assessment of the "wholesomeness" of a food.

Background A persistent gap remains between evidence-based health care and its application in routine practice. This challenge is particularly prominent in allied health professions like occupational therapy (OT), where interventions are complex, individualized and centred on patients' daily functioning. Objective To identify barriers, facilitators, and implementation strategies for integrating evidence-based OT interventions in multiple sclerosis (MS) rehabilitation. Methods A mapping review was conducted using searches in five databases. Eligible studies included adults with MS, examined OT interventions, and reported on factors influencing implementation. Data were extracted and categorized using Grol’s framework for barriers/facilitators and Mazza’s taxonomy for implementation strategies. Results Fifteen studies met inclusion criteria. Barriers and facilitators were identified at multiple levels of Grol’s framework: 1-Innovation-level: accessibility, feasibility, and perceived attractiveness supported implementation, particularly when interventions incorporated holistic approaches, gamification, or printed manuals. 2-Professional-level: therapists’ competencies and alignment between interventions and patients’ priorities. 3-Patient-related: facilitators included motivation, readiness to change, and peer support, whereas fatigue, pain, and cognitive challenges served as barriers. 4-Social and organizational: effective teamwork, resource availability, and flexible scheduling facilitated successful adoption. 5-Economic or political: no studies. Implementation strategies focused on using manuals, patient empowerment, gamification, and organizational supports. No financial or structural policy-level strategies were identified. Conclusion Successful implementation of evidence-based OT for MS requires multifaceted, context-sensitive strategies addressing innovation, professional, patient, and organizational determinants. Practical approaches enhance uptake, while substantial gaps persist at economic and policy levels. Strengthening these areas may improve longterm integration and sustainability of evidence-based OT in MS rehabilitation.

Background/Aim Sleep disturbances are common and are associated with impaired daytime functioning, reduced quality of life, and increased health risks. Non-pharmacological neuromodulatory interventions have gained interest as alternatives to hypnotic medication. Pulsed electromagnetic field (PEMF) therapy has been proposed as a non-invasive approach to improve sleep quality and recovery, but evidence from large, well-controlled trials remains limited. The objective of this study was to evaluate the efficacy and safety of pulsed magnetic field therapy (PMT) on sleep quality, sleep-related symptoms, daytime functioning, and well-being in adults with heterogeneous sleep complaints. Materials and Methods In this remote, randomized, double-blind, placebo-controlled trial, 217 adults reporting non-restorative sleep, difficulties initiating sleep, or frequent nocturnal awakenings were assigned to active PMT using a PEMF device (Night Harmony Female/Male protocol) or a sham application for three weeks. Primary outcomes were changes in the Pittsburgh Sleep Quality Index (PSQI) global score and self-rated sleep satisfaction, restfulness, and sleep initiation difficulties. Secondary outcomes included sleep diary measures, daytime functioning, well-being (WHO-5), symptom burden (MYMOP), and daytime sleepiness (Epworth Sleepiness Scale). Analyses followed the intention-to-treat principle using ANCOVA with baseline values of the respective parameter as covariate. Results Both groups showed significant improvements over time in global sleep quality and most secondary outcomes (p < 0.001). Between-group differences in PSQI global score were not significant (p = 0.314). However, active PMT resulted in significantly greater improvements in subjective sleep satisfaction (p = 0.02) and restfulness (p = 0.02), particularly among participants with moderate to severe baseline sleep disturbances (p < 0.001 for both). Sleep continuity measures improved similarly in both groups. No serious adverse events were reported. Conclusions PMT produced modest but significant improvements in subjective restorative aspects of sleep beyond placebo effects and was well tolerated. Further studies using objective sleep measures and longer follow-up are warranted.

Intensive Short-Term Dynamic Psychotherapy (ISTDP) has proven effective in over 120 outcome studies, particularly for anxiety, depression, and personality disorders. This conceptual paper proposes a theoretical integration of ISTDP with Solution- Focused Brief Therapy (SFBT) and clinical hypnosis. Each modality offers unique strengths—ISTDP enables rapid emotional processing, SFBT builds client resilience and solutions, and hypnosis enhances neuroplasticity and emotional receptivity. Drawing on existing empirical and neuroscientific literature, this paper synthesizes these modalities into a unified clinical framework. The integrated model emphasizes accelerated change through emotional access, strategic future orientation, and unconscious facilitation. Case examples illustrate the framework's practical applications across complex clinical presentations. The integration addresses gaps in single-modality treatments and provides a cost-effective, neurobiologically supported method of intervention. This article offers clinicians structured decision- making strategies and practical tools for real-time integration, while outlining future directions for empirical research.

The incidence rate of melasma is notably high among patients with anxiety disorders. Aromatherapy primarily influences the physiological and psychological states of individuals through the inhalation or application of essential oils, thereby facilitating the treatment or alleviation of various conditions. This study aims to explore the action mechanism of complex lemon-angelica sinensis -boswellia essential oil (CEO) in treating anxiety disorders with melasma. We investigated the active ingredients, targets, and pathways of CEO in relation to anxiety and melasma using network pharmacology. We employed cell assays and conducted nebulized essential oil inhalation tests on CUMS mice to validate the intervention effects of CEO on anxiety. A total of 28 active components, including neryl acetate, 3-butenylphthalide and octyl acetate, and 26 cross-targets, such as ESR1, CCND1 and PIK3CA, were identified. GO and KEGG pathway analyses indicated that these cross-targets were primarily involved in endocrine regulation, cell proliferation, and apoptosis, specifically through PI3K/Akt signaling pathway and calcium signaling pathway. The experimental results demonstrated that CEO significantly reduced the secretion of NO, TNF-a and IL-6, as well as the mRNA expressions of ESR1, CCND1 and PIK3CA in cells compared to the inflammatory cell model. Furthermore, CEO notably decreased the forced swimming immobility time of mice and the levels of IL-1β, ESR1 and CCND1 in hippocampus when compared to model mice. These findings suggest that CEO may regulate ESR1, CCND1 and PIK3CA through its citral, 3-butylphthalate and neryl acetate, thereby influencing endocrine function, cell proliferation and apoptosis, inhibiting inflammation and anxiety-like behavior in CUMS-induced mice.

Standardizing use of mepiquat chloride for higher productivity of densely planted Bt cotton variety” was carried out at the Regional Research Station, Abohar and Regional Research Station, Faridkot during the kharif season of 2021 on Btcotton variety PAU Bt3. The soil of experimental field was silty loam at Abohar and sandy loam at Faridkot. The experiment was laid out in a split plot design with four plant spacings (67.5×15 cm, 67.5×30 cm, 67.5×45 cm and 67.5×60 cm) as main plots and five Mepiquat chloride levels (MC (5%) @ 375 ml ha-1 at squaring, MC (5%) @ 375 ml ha-1 at flowering, MC (5%) @ 750 ml ha-1 at squaring, MC (5%) @ 750 ml ha-1 at flowering and after 15 days and Control (No MC)) as sub plots with three replications. Lowest plant density (67.5×60 cm) and MC (5%) @ 750 ml ha-1 at squaring resulted in significant reduction of plant height, LAI (Leaf Area Index) and dry matter as compared to control at both the locations. Higher boll retention and opened bolls were observed in 67.5×60 cm and MC (5%) @ 750 ml ha-1at flowering. There was no significant effect of both the treatments factors on node count, monopods and sympods. Highest seed cotton yield was obtained with 67.5 ×30 cm (at Abohar) and 67.5×15 cm (at Faridkot) although these two spacing levels were at par with each other. MC (5%) @ 750 ml ha-1 at flowering resulted in 22.9% and 21.3% increase in seed cotton yield over control at Abohar and Faridkot, respectively. Different plant spacings and mepiquat chloride applications showed a non-significant effect on different fibre quality parameters except halo length at Faridkot. At both the locations, highest B:C ratio was observed in 67.5×30 cm and MC @ 750 ml ha-1 at flowering.

Artificial Intelligence (AI) is emerging as a transformative force across many sectors, with healthcare representing both one of the most promising and most challenging areas of application. This review summarizes current and future applications of AI in healthcare, focusing on its potential to improve diagnosis, therapy, chronic disease management, and overall patient care, while also alleviating physicians’ workload. Recent literature demonstrates that AI systems can reduce diagnostic errors/delays by mitigating cognitive biases, support imaging and pathology through improved accuracy and speed, and prevent prescribing errors by integrating pharmacogenomic and clinical data into decision-support systems. In chronic disease management, AI-powered wearable devices enable continuous monitoring and early detection of conditions such as atrial fibrillation, thereby reducing the risk of stroke and long-term disability, particularly in elderly people. Therapeutic applications include AI-driven drug discovery, personalized oncology, and tailored medicine that integrates multi-omics and lifestyle data. Beyond direct medical intervention, AI contributes by automating routine tasks, optimizing workflows, and facilitating greater patient–clinician interaction. Despite these benefits, significant challenges remain, including issues of data quality, privacy, security, equity, and the need for transparency and trust in “black box” systems. Looking ahead, the integration of multimodal data, digital twins, and robotics is expected to advance more comprehensive, equitable, and human-centered care. We conclude that, when applied ethically and responsibly, AI should not replace clinicians but rather serve as a powerful partner that enhances medicine by restoring empathy and humanity.

Background and Objectives Platelets are small, anucleate blood cells produced in the bone marrow, primarily involved in blood coagulation. Platelet concentrate is a vital blood product with extensive applications. However, its short lifespan and limited donor availability pose global challenges. This study aimed to follow the trend of platelets 5 during days of storage. Material and Methods We studied on 40 platelet bags and analyzed glucose levels, lactate dehydrogenase (LDH), bacterial culture, and apoptosis using flow cytometry with Annexin V-PI over three consecutive days (first, third, and fifth) post-blood collection. Data were analyzed using SPSS. Results No significant correlations were found between age, blood group, or gender and the variables studied. No bacterial growth was detected. Glucose levels decreased significantly from day 1 (382 mg/dl) to day 5 (298 mg/dl). The average platelet apoptosis increased significantly from 3.65% on day 1 to 9.06% on day 5. Significant correlations were observed between glucose levels and apoptosis on days 3 (p<0.05) and 5 (p<0.01). No correlation found between LDH and apoptosis or necrosis, although a significant relationship between necrosis and apoptosis was noted on day 5 (p=0.003). Conclusion These findings suggest that while demographic factors do not influence the studied variables, the significant decrease in glucose levels correlates with increased platelet apoptosis over time, highlighting potential metabolic interactions that warrant further investigation. Highlights 1. The study revealed subtle variations in metabolic markers related to donor demographics, particularly gender and age. Understanding these differences can inform targeted donor selection strategies to optimize platelet quality. 2. A significant negative correlation was found between glucose levels and apoptosis rates, indicating that as glucose decreases, platelet viability declines. This relationship highlights the need for careful monitoring of glucose levels during storage to maintain platelet function. 3. Fluctuations in lactate dehydrogenase (LDH) levels were correlated with increasing rates of apoptosis, suggesting that LDH could serve as a valuable biomarker for assessing platelet quality throughout the storage period. This finding could lead to improved storage protocols and enhanced transfusion safety.

Wheat is a staple grain crop in the United States and around the world. Weed infestation, particularly grass weeds, poses significant challenges to wheat production, competing for resources and reducing grain yield and quality. Effective weed management practices, including early identification and targeted herbicide application are essential to avoid economic losses. Recent advancements in unmanned aerial vehicles (UAVs) and artificial intelligence (AI), offer promising solutions for early weed detection and management, improving efficiency and reducing negative environment impact. The integration of robotics and information technology has enabled the development of automated weed detection systems, reducing the reliance on manual scouting and intervention. Various sensors in conjunction with proximal and remote sensing techniques have the capability to capture detailed information about crop and weed characteristics. Additionally, multi-spectral and hyperspectral sensors have proven highly effective in weed vs crop detection, enabling early intervention and precise weed management. The data from various sensors consecutively processed with the help of machine learning and deep learning models (DL), notably Convolutional Neural Networks (CNNs) method have shown superior performance in handling large datasets, extracting intricate features, and achieving high accuracy in weed classification at various growth stages in numerous crops. However, the application of deep learning models in grass weed detection for wheat crops remains underexplored, presenting an opportunity for further research and innovation. In this review we underscore the potential of automated grass weed detection systems in enhancing weed management practices in wheat cropping systems. Future research should focus on refining existing techniques, comparing ML and DL models for accuracy and efficiency, and integrating UAV-based mapping with AI algorithms for proactive weed control strategies. By harnessing the power of AI and machine learning, automated weed detection holds the key to sustainable and efficient weed management in wheat cropping systems.

Background Beta-Sitosterol (SIT) is an active TCM compound employed to treat diabetic retinopathy (DR). A network pharmacology approach to understanding the active ingredients and the therapeutic mechanisms underlying DR has not been pursued. Methods The potential targets for DM were identified according to the MedGene, Gendome, HGNC, OMIM, GeneCards, PheGenI, GEO, and STRING database. The herb and components were predicted and screened by network pharmacology through oral bioavailability and drug-likeness filtration using the Traditional Chinese Medicine Systems Pharmacology Analysis Platform database. A network pharmacology prediction and network analysis were used to predict the active potential targets and pathways of SIT application to DR. Results We found the Top 15 DR-related genes by screening in 9 databases. 26 kinds of TCM and nearly 300 kinds of active ingredients. SIT exists in 10 kinds of DR-treat TCM. The comprehensive network pharmacology approach was successful in identifying 23 kinds of core genes for SIT treating DR. ERBB3 and IGF2-related PI3K-Akt signaling pathway or EDN3, IGF2 and SPP1-related receptor ligand activity pathway might be the main pharmacological targets, and pathways in DR. We speculated that SIT was effective for the treatment of DR. Conclusion Based on the network pharmacology, we predicted the potential targets of SIT in treating DR and helped to illustrate the mechanism of action. Our study identifies key genes and pathways associated with the prognosis and pathogenesis of DR from new insights.

Experiments were conducted to evaluate the response of different sorghum varieties to micro-dosing fertilization strategies on yield and yield traits, as well as the impact on nitrogen fertilizer and water use efficiency (NUE and WUE). In addition, the benefit-cost ratio of sorghum cultivation under different fertilization strategies in the Sudan savanna zone of Nigeria was analyzed. The experiment included eight fertilizer micro-application strategies as well as two control and three sorghum varieties. Our results showed that most agronomic indicators differed significantly between years, varieties, and fertilization strategies. However, the application of 100g hill-1 poultry manure plus 3g NPK hill-1 resulted in the highest average grain yield > 2000 kg ha-1 at both study sites (BUK and Minjibir). This means that the grain yield is 86% and 132% higher than the average grain yield with zero fertilization. There were extremely significant differences between NUE and WUE fertilization strategies and varieties at the two sites. At BUK and Minjibir, NPK applied with 3 g of hill-1 had the highest NUE with an average of 37.6 and 40 kg grain/kg N. Application of 100 g of poultry manure plus 3g of NPK hill-1 resulted in the highest average WUE of 6.1 and 5.6 kg grain/mm for BUK and Minjibir, respectively. BUK (3.2) and Minjibir (3.6) had the highest net income and benefit-to-cost ratios when applying 3 grams of NPK per hill. The adoption of micro-dosing fertilization strategies by smallholder farmers provides a good opportunity to prevent long-term soil fertility limitations and thereby increase sorghum productivity and farmer incomes by recommending multiple-choice fertilization strategies for improved sorghum varieties.

Introduction The arrangement of teaching content to relate to or unite concepts that are regularly taught in different academic courses or departments is referred to as integration of teaching. It simply refers to creating links between theoretical knowledge and actual application. Teaching the fundamental sciences in separate blocks prevents students from having the opportunity to connect and integrate their newly acquired knowledge. Objectives To evaluate the effectiveness of Integrated teaching method over traditional teaching and perception of students towards integrated method among first MBBS students Methodology The total of 62MBBS first year students are randomly divided into two groups, with 31 in each group. Group A is subjected for Conventional teaching and Group B for Integrated teaching method in the same topic. Among the 2 sessions one session is Horizontal and other is Vertical method of integrated teaching have been implemented. Finally, an evaluation test was conducted for both the groups and the mean marks obtained by the students were analyzed by using SPSS software version 17. Student’s perception towards this method was evaluated by pre-validated feedback questionnaire and analyzed. Results The mean marks (outof40) obtained by Group B (Conventional teaching) is 13.82 and by Group A (Integrated Teaching) is 31.18. So, the marks obtained by students after integrated method were found to be higher than the other group which underwent conventional teaching and this difference was found to be statistically significant (P <0.0001). Discussion and conclusion In comparison to the typical conventional method, integrated teaching has been found to be a more successful mode of instruction in terms of students' performance and assessment exams.

Knee joint osteoarthritis, a chronic condition resulting in considerable disability, particularly in later life, not only impacts life quality significantly and severely, but is also strongly associated with the persistence of intractable pain, depression, helplessness, and a high falls injury risk. This narrative overview synthesizes the knowledge base regarding painful knee osteoarthritis and what is known about Tai Chi exercise participation in the context of reducing knee joint disability and its associated risk of one or more injurious falls, as well as pain and depression. To this end, all relevant articles published in the English language on the topic were sought. While most reports rely on Eastern observations, rather than Western medicine studies, collectively, these data reveal that Tai Chi practiced widely in Asia for many centuries may have an enormous positive impact on reducing distress and increasing function and autonomy among older adults living in the community and diagnosed as having knee osteoarthritis. They specifically suggest the increasing numbers of older adults diagnosed as having knee osteoarthritis can safely practice selected Tai Chi exercises with the expectation that consistent applications will enhance mobility, reduce pain and depression, plus instability and possible injurious falls, while reducing fatigue, even if surgery is forthcoming.

Reproductive performance is an essential trait of cows in dairy cattle. The effect of different factors on reproductive performances and sex ratio difference in dairy cattle were not well documented in Ethiopia. In this research, cross-sectional study was conducted from December 2021 to June 2022 in Hawassa city to assess reproductive performances and effect of breeding methods on sex ratio difference of newborn. Questionnaires and observational study were used to collect data. In this study, the mean+SE of age at first service was 17.53+0.035 with difference of relatively one month from onset of puberty. The mean number of services per conception was higher in animals breed naturally (1.87+0.056) as compared to AI (1.69+0.049). Higher conception rate of 74.26% was obtained in age group of <4years as compared to old age >6years at rate of 4.11% with statistically significant difference (P<0.05). Animals with medium level of milk production (15-20L/day) more conceived to first service 43.14% than higher milk production group (20-25L/day) with 35.59%. The presence of reproductive problems significantly affect conception rate to first service with higher conception rate of 54.47% in negative animals and 22.41% in animals with reproductive problems. Conception rate was increased with increasing number of services in both breeding types. Sex of newborn was not significantly affected by breeding methods used and difference in the study area. Generally this research found that reproductive performances and use of AI in the study area were satisfactory even though age, level of milk production and presence of reproductive health problems had significant impacts on performances. In order to sustain and improve reproductive performances age, reproductive health problems and breeding management should be considered. Therefore, reproductive health management and application of AI for genetic improvement should be well practiced to improve dairy cattle reproductive performances.

Polymer electrolyte membrane (PEM) technologies hold promise for sustainable energy solutions, yet pinhole-related challenges persist. Our research introduces a novel biohybrid approach to self-healing, enhancing multiple healing cycles with minimal membrane disruption. Initial steps involve immobilizing enzymes on a polymeric membrane. This study establishes the immobilization process and analytical framework through enzyme immobilization on polypropylene. Applicability and stability are investigated, laying groundwork for potential Nafion™ applications and advancing climate neutral energy. Qualitative analysis employs colorimetric p-NPA assay on polypropylene-immobilized lipase from Candida rugosa (CRL) and Lipase B from Candida antarctica (CALB). Both enzymes hold their temperature optimum at 50°C which is increased by 10°C via immobilization. Diisopropylcarbodiimide (DIC) is optimal for immobilization. Synchronous enzyme and DIC addition is advantageous. After 8 reuse cycles, immobilized enzymes retain 54.3% residual activity. Immobilizates exposed to PEM fuel cell conditions show better stability due to covalent immobilization than free CRL. Yet, declines occur under stressors like 60 °C and concentrated alcohol. Immobilizates remain resilient at pH 3 and under oxidizing as well as reducing conditions constituted by varied gas atmospheres. Considering PEM fuel cells' operational range, in-depth investigations across conditions are vital. Future studies target long-term PEM fuel cell lifespans, focusing on extremophilic enzymes or modifications for high-temperature stability. Subsequently, the transferability of the immobilization method to Nafion™ shall be deliberated based on the outcomes.

The increasing demand for environmentally-friendly materials has led to a surge in research on the production of biodegradable polymers. In this study, we investigate the synthesis of a biodegradable polymer by graft copolymerization of gum Arabic (GA) and polyethylene glycol (PEG). GA, a natural polysaccharide and PEG, a synthetic water-soluble polymer, were used as the backbone and graft monomer, respectively. The graft copolymerization was carried out using benzoyl peroxide as an initiator and performed under nitrogen atmosphere. The resulting polymer was characterized by Fourier transform infrared (FTIR) spectroscopy, Xray diffraction (XRD), thermogravimetric analysis (TGA), and scanning electron microscopy (SEM). The FTIR spectra confirmed the formation of the graft copolymer, and TGA analysis showed that the copolymer had higher thermal stability than GA. The DTA thermograms indicated two thermal events. The evaporation of water and organic polyethylene glycol components was measured, and the first mass loss was due to the loss of adsorbed and structural water in the gum Arabic, which occurred between 31.87 and 180°C, while the second, corresponding to the pyrolysis of polyethylene glycol functional groups and polysaccharide decomposition, resulted in a 70% mass loss. SEM morphological analysis of gum Arabic showed aggregates of high irregularity in particle shape. The cracks and holes obtained in the Gum Arabic micrograph disappeared from the new gum Arabic-graft-polyethylene glycol, leaving a smooth surface with scattered particles in the image, which was due to the grafting copolymer. From the XRD patterns, the percentages of the amorphous and crystalline phases were determined. The results show that gum Arabic has a 78% degree of crystallinity, whereas gum Arabic-graft-polyethylene glycol has the lowest value of 51%. Biodegradation activity was observed using the fungus Aspergillus flavus on different days on gum Arabic-g-polyethylene glycol. The results clearly showed inhibition zones with a change in the state of the copolymer from solid to liquid from days 8 to 14. These results indicate that the GA-PEG copolymer has potential as a biodegradable material for use in various applications, such as packaging, agriculture, and medical industries.

Strube Sudan 01/14, Strube Sudan 02/14, Strube Sudan 04/14, Strube Sudan 05/14 and Strube Sudan 06/14, and the nitrogen levels were viz, 0, 80 and 120 kg urea per ha; applied twice (at the sowing and then 4 weeks after sowing). The evaluated components were; leaf number/plant, leaf area index (LAI), root length, root diameter, fresh and dry weight of foliage/plant, fresh and dry weight of root/plant; all determined at 5 terms. While Crop Growth Rates (CGR), Relative Growth Rate (RGR) and Net Assimilation Rate (NAR); determined at different periods of growth (intervals). The analysis of variance (ANOVA) revealed that at 4 weeks after sowing (WAS): leaf number (14.33- 17.03) , root length (19.05 – 21.75 cm), root diameter ( 7.93- 8.40 cm) foliage fresh ( 186.93 – 292.06 g) and dry ( 69.00 – 94.10 g) weight per plant, root fresh (72.66 – 108.88 g) and dry weight ( 12.54 – 22.08 g) per plant differed significantly (P≤ 0.05); at 7 and 10 WAS leaf number (22.39 -35.73 and 26.91 – 38.47, respectively), LAI ( 3.725 -5.645) , fresh and dry root weight per plant ( 586.78 – 913.81an 189.06 – 326.43 g, respectively) differed significantly; at 13 WAS: dry foliage weight ( 69.00 – 94.10 g), LAI ( 2.603 – 4.744), root diameter (10.09 – 11.92 cm) differed significantly; at 16 WAS only dry foliage (44.34 – 73.48 g) weight reflected significance. All other cases reflected insignificant differences among the evaluated genotypes. Moreover, all the studied components reflected insignificant differences among the nitrogen fertilizer levels and likewise genotype x nitrogen interaction (G x N) at the 5 sampled terms. Nevertheless, CGR, RGR and NAR displayed insignificant effect on the studied components in the evaluated periods.

Tactile information plays an important role in human manipulation of objects; however, prosthetic limb placement or teleoperation requires the manipulation of alternative bodies in the absence of tactile sensations. To provide an alternative to tactile sensation, this study proposes and assesses a continuous feedback scheme with temporally coded vibration. This scheme was designed to provide discrete intended tactile information in response to changing object-controlled situations by repetitively presenting time-coded vibration patterns. The effects of the proposed scheme on an object with acatch-and-hold task in virtual reality were confirmed. Compared to the control feedback scheme that provides vibration only when the balance of the virtual grip force and object position is changed, the proposed feedback scheme has a better effect in terms of the success rate of holding on to the object with an appropriate holding force during the task. The effect is larger, especially in the invisible task condition, suggesting that the increased amount of information with coded vibration patterns can be used without any special training, especially without visual information. Considering the existing studies that show the effect of a feedback scheme in response to motion events, the continuous feedback scheme proposed in this study may be more suitable for movements that require sequential coordination and passive responses than stimulation methods based on motion events. This feedback scheme has potential applications not only in tele-technology but also in healthcare, such as rehabilitation.

Background Growing scientific evidence points to the benefits of human milk for the growth and development of a newborn. Compelling evidence has confirmed the benefits not only for full-term babies but also for preterm infants. Objective This survey was planned by the Italian Ministry of Health together with the Italian Association of Donor Human Milk Banks (AIBLUD) and aimed to evaluate the activity of human milk banks (HMBs) in Italy in the period 2018-2020, analyzing several items and the impact of the COVID-19 pandemic. Methods Following the two surveys performed in 2012 and 2016, a third survey was planned in the year 2021 to evaluate possible changes in the activity of the Human Milk Banks (HMBs) operating in Italy. A questionnaire was sent to all the 41 HMBs officially operating in Italy in the year 2021 with the purpose to obtain national data concerning milk banks activity, number of donors, volume of human milk collected, and other information related to the years 2018, 2019 and 2020. Additional questions related to the impact of the COVID-19 on the activity of HMBs in the year 2020 were included. Therefore the questionnaire proposed in this third survey collected fundamental data on the donation of human milk with the implications related to the COVID-19 pandemic. Results 90% of the banks (37/41) responded to this survey. The collected data confirm the results of the second survey (2016), with a high level of adherence to the Ministerial Guidelines and the AIBLUD recommendations. The application of the principles of the HACCP system continues to improve (89%), while in the last three years there has been a sharp decline in the home collection service for donor human milk (68%). This decline is mainly linked to the interruption of this service due to the limitations imposed by the pandemic. In 2020 (the year of the COVID-19 pandemic) there was a clear reduction in the number of donors with a return to the values of 2016. The volumes of milk collected, and the average duration of donation, however, remained high. The reasons linked to the reduction in the number of donors are described. Conclusion This survey underlines the high quality standard of Italian HMBs and the usefulness of this service for the national health policy. Despite the difficulties due to the COVID-19 pandemic, the Italian HMBs have maintained an efficient and safe service and have guaranteed the collection of satisfactory volumes of donor milk. Lack of information represents the most important barrier to the donation of human milk.

Tay-Sachs disease (TSD) is a rare neurodegenerative disorder caused by mutations in the HEXA gene, which encodes the ɑ subunit of the enzyme β-hexosaminidase A. Lacking this key enzyme in GM2 ganglioside catabolism, individuals who are homozygous for HEXA mutations suffer from abnormal accumulation of GM2 ganglioside in brain and nerve cells, ultimately resulting in the progressive deterioration of the central nervous system. TSD is one of three disorders characterized by β-hexosaminidase deficiency; Sandhoff disease (SD) and the AB variant arise by mutations in the HEXB and GM2A genes respectively, which disrupt other points of GM2 ganglioside degradation. Characterized by developmental delay and stagnation, muscular weakness, coordination deficits, seizures, and eventual hearing and vision loss, these three disorders are clinically indistinguishable and occur in three forms defined by age of onset. While there is a much higher incidence of TSD in the Ashkenazi Jewish population, community carrier screening and counseling initiatives have reduced disease prevalence to about the equivalent of non-Jewish populations; however, such efforts have raised ethical concerns in the Jewish community that are increasingly relevant in light of scientific and medical advancements. Currently, treatments for TSD and its related disorders focus on symptom management, with gene therapies and the application of modified CRISPR-Cas-9 technology being explored.

Sclerotiniasclerotiorum, the causal agent for white mold (Sclerotinia stem rot), is a devastating fungal pathogen. Currently, Sclerotinia is most commonly managed using the chemical fungicide which can lead to Sclerotinia resistance development, impacting biodiversity and interfering with key ecosystem services. In this regards, field experiments were conducted during 2017-18 planting seasons to evaluate the efficacy of different components viz. sawdust burning, stable bleaching powder, fungal and bacterial bio-control agents, chemical fungicide Rovral 50 WP and integration of different components for the management white mold disease of bush bean, mustard and garden pea in three different locations viz. in the field of Plant Pathology Division, Bangladesh Agricultural Research Institute, Joydebpur, Gazipur, Regional Agricultural Research Station (RARS), Burirhat, Rangpur and RARS, Ishurdi, Pabna, respectively. The results showed that different treatments displayed varying levels of effectiveness against the disease. All the treatments gave satisfactory reduction of white mold disease development and increased plant growth as well as yield of bush bean, mustard and garden pea. Among the treatments, integration of saw dust burning + soil amendments with Trichoderma based bio-fungicide + bacillus based bio-control agents + application fungicide Rovral 50 WP is the best treatment which reduced 97.49%, 77.72%, 72.26% white mold disease incidence and 84.61%, 81.14%, 71.01% white mold disease severity of mustard, bush bean and garden pea, respectively and increasing plant growth parameter as well as 52.16%, 27.74%, 36.97% yield of mustard, bush bean and garden pea, respectively. Application of only fungicide Rovral 50 WP also better treatment in reduction of white mold disease incidence and disease severity and increasing plant growth parameter as well as increasing yield of mustard, bush bean and garden pea. Soil amendment with fungal or bacterial bio-control agents also gave satisfactory results in reduction of white mold disease incidence and disease severity and increasing plant growth parameter as well as increasing yield of mustard, bush bean and garden pea. It could be concluded from the obtained results that integration between bio-control agents as a soil treatment and foliar application chemical fungicide might be useful as a good tool for controlling white mold disease caused by S.sclerotiorum and obtained higher yield of bush bean, mustard and garden pea under field condition.

Background Cameroon is battling against the novel coronavirus (COVID-19) pandemic. Although several control measures have been implemented, the epidemic continues to progress. This paper analyses the evolution of the pandemic in Cameroon and attempts to provide insight on the evolution of COVID-19 within the country’s population. Methods A susceptible-infected-recovered-dead (SIRD)-like model coupled with a discrete time-dependent Markov chain was applied to predict COVID-19 distribution and assess the risk of death. Two main assumptions were examined in a 10-state and 3-state Markov chain: i) a recovered person can get infected again; ii) the person will remain recovered. The COVID-19 data collected in Cameroon during the period of March 6 to July 30, 2020 were used in the analysis. Results COVID-19 epidemic showed several peaks. The reproductive number was 3.08 between May 18 and May 31; 2.75 between June 1 and June 25, and 2.84 between June 16 and June 24. The number of infected individuals ranged from 17632 to 26424 (June 1 to June 15), and 28100 to 36628 (June 16 to June 24). The month of January 2021 was estimated as the last epidemic peak. Under the assumption that a recovered person will get infected again with probability 0.15, 50000 iterations of the Markov chain (10 and 3- state) demonstrated that the death state was the most probable state. The estimated lethality rate was 0.44, 95%CI=0.10%-0.79%. Mean lethality rate assuming ii) was 0.10. Computation of transition probabilities from reported data revealed a significant increase in the number of active cases throughout July and August, 2020, with a mean lethality rate of 3% by September 2020. Conclusion Multiple approaches to data analysis is a fundamental step for managing and controlling COVID-19 in Cameroon. The rate of transmission of COVID-19 is growing fast because of insufficient implementation of public health measures. While the epidemic is spreading, assessment of major factors that contribute to COVID-19-associated mortality may provide the country’s public health system with strategies to reduce the burden of the disease. The model outputs present the threatening nature of the disease and its consequences. Considering the model outputs and taking concrete actions may enhance the implementation of current public health intervention strategies in Cameroon. Strict application of preventive measures, such as wearing masks and social distancing, could be reinforced before and after the opening of learning institutions (schools and universities) in the 2020/2021 calendar year and next.

Cancer cells need strong drug to be eliminated. Cancer lesions cure could achieve by topical application of crude bee venom. Bee venom medication used to prevent malignancies in groups most at risk (predisposing factors). Bee venom crosses the blood brain barriers because its components are very small. However, Bee venom contraindicated administered by intravenous injection because it’s hemolytic substance, mellitin which is powerful anticoagulant. However, the cationic peptides mellitin govern the mode of action of bee venom as anticancer and antiviral in vivo; 1 there is a negative charge on cancer cells, viral infected cells, diseased cells, and generally any cells that contain toxins or damage, and viruses are carrying negative charge even when it is outside the living body. 2Bee venom component (melittin) carries a positive charge, it destruct negatively charged cancer cells. 3 The role that the herpes virus is likely to play in increasing the severity of cancerous diseases, worsen the conditions: herpes viruses are opportunistic viruses that strike the body whose immunity is weakened for any reason. Therefore, the role of herpes virus must be neutralized when you planning to treat a cancer patient. Fortunately, bee venom is a powerful antiviral, and thus we hit three birds with one stone, that is, we kill cancer cells, kill opportunistic viruses, and improve tissue immunity to participate in the fight against cancer and get rid of toxic exudates more efficiently.

In India, loss of fertility through soil erosion is primarily a summer monsoons mediated phenomenon. Reversing the land degradation processes contribute to water availability, soil fertility maintenance, adapting to climate change and overall food security. Whereas kharif (monsoon/rainy season crop) foodgrain production largely depends on summer monsoons, the rabi season (post-rainy season/winter crop) rainfall is too little to exert a direct influence. In spite of larger acreage under kharif foodgrain crops, total fertiliser consumption during kharif and rabi seasons is comparable. Negative rainfall anomalies (deficit) adversely affected total fertiliser consumption and their use efficiency. Despite significant differences in fertiliser application rates, the response to applied fertiliser nutrients is almost similar in the two seasons. This implies that nutrient use efficiency (NUE) has a ‘manageable’ and an ‘unmanageable’ component wherein 4R practices are difficult to implement under unfavourable kharif weather conditions. Partial factor productivity of fertilizer nutrients (PFPF) has continuously declined over decades mainly because of depletion of soil organic carbon, imbalanced use of nutrients and inability to maintain soil moisture supplies. These observations plus yield-gap analysis permitted us to conclude that past trends of declining NUE can only be reversed through a shift either in sustainable land management practices or enhancing the genetic yield potential/ biomass of crop cultivars or by combining both and making kharif crop planting independent of monsoons rains through direct dry seeding.

In this theoretical discovery of a law of Life, there is MATHEMATICS (Geometry, Bits and Numbers) that UNIFY 3 universes as complementary as ATOMIC MASS, WAVES, and INFORMATION (DNA, RNA and Amino Acids). The discovery of a simple numerical formula for the projection of all the atomic mass of life-sustaining CONHSP bioatoms leads to the emergence of a set of Nested CODES unifying all the biological, genetic and genomic components by unifying them from bioatoms up to 'to whole genomes. In particular, we demonstrate the existence of a digital meta-code common to the three languages of biology that are RNA, DNA and amino acid sequences. Through this meta-code, genomic and proteomic images appear almost analogous and correlated. The analysis of the textures of these images then reveals a binary code as well as an undulatory code whose analysis on the human genome makes it possible to predict the alternating bands constituting the cariotypes of the chromosomes. The application of these codes to perspectives in astrobiology, cancer, and specifically in INFORMATION THEORY with the emergence of binary codes and regions of local stability (voting process), whose fractal nature we demonstrate, is illustrated. PREFACE by Professor Luc Montagnier Addendum by Robert Friedman M.D After the discovery of the DNA double helix structure allowing both the stable storage of genetic information and its transfer through messenger RNA to protein synthesis organelles themselves structured by RNA most abundant in cells, the ribosomal. This wonder of nature exists in ALL living beings from the virus to humans and is based on two codes, the linear sequence of nucleotides and that derived from codons where three nucleotides allow with a certain flexibility - synonymous codons - the choice in the twenty amino acids. But we are missing a third CODE the one governing at multicellular beings from the rotifer to human, the stabilized modulation of gene expression in a nutshell the differentiation of cells from the single cell of the fertilized egg. It is logical to think that this program which begins as soon as fertilization is written in the DNA. We are also prone to associate it with non-coding DNA sequences although they control gene expression. I introduce here the notion developed by Jean-Claude Pérez of mathematical harmony, a higher order present in all living beings and whose existence it finds in genomes, including those of viruses. Thus the natural evolution of variants of the genome of coronavirus Covid 19 tends towards increasingly long Fibonacci series. It remains to determine the Who, the How and the Why of such developments. I will bet with my mathematician colleague that waves and fractals play a role. Luc Montagnier ADDENDUM Jean-claude has given scientists a strong new direction for research. He has identified a unified field of science guided by the Golden Ratio and Fibonacci Sequence. By identifying an overall guiding principle that makes possible fractal-like nesting at all levels of biological manifestation, future researchers can begin with the "whole" instead of the "parts". If we know that complex systems are organized at varying levels by the Golden Ratio and Fibonacci Sequence, we can look for those universal patterns first and then fill in the gaps with small details to complete the picture. It's like having an overall view of a crossword puzzle before beginning to assemble the individual pieces. Without an overarching vision and guiding principle, completing the puzzle is infinitely more difficult. Once scientists and researchers realize and begin using this "SECRET IN HIDDEN IN PLAIN SIGHT," their discoveries will be orders of magnitude more fruitful. Robert Friedman M.D

The impact of the environment on the development of non-communicable chronic diseases has gained prominence in recent years. In this context, a new chemical exposure assessment strategy is needed that is capable of revealing multiple exposures, as well as reflecting the cumulative interaction between such environmental contaminants in the biological system. From this perspective, metabolomics emerges as a promising tool in this field of knowledge, since it is able to identify changes in metabolism and/or gene expression resulting from exposure to environmental factors. The aim of this study was to describe important concepts, as well as the steps that permeate the metabolomics analysis, and also to present some relevant works with the application of metabolomics in the assessment of chemical exposure. A literature review showed a significant increase in the use of metabolomics in environmental toxicology in recent years. This increase is mainly due to advances in analytical techniques and the improvement of data processing tools. However, this field of investigation remains little explored, especially with regard to the study of toxicity associated with chronic exposure to low levels of chemical agents. Thus, it is urgent that omic biomarkers can be used as a tool for decision-making, especially with a view to protecting, diagnosing and recovering human health.

When lipids are exposed to heat, light and oxygen, it leads to oxidation. The addition of antioxidants is required to preserve colour, flavour and vitamin destruction. Present study was, therefore, planned to investigate pod coat of pigeon pea as possible sources of natural antioxidants and to assess their efficacy in stabilization of crude soybean oil during normal storage (28 days at 50°C). Study revealed that acetone pod coat extract of pigeon pea showed richness in total phenolics (17.72 mg/g), flavonoids (9.00 mg/g) and tannins (2.21 mg/g) while the extract of ethyl acetate was found enriched in tocopherols content (9.56 mg/g). The IC50 value of acetone extract was found to be lowest, exhibited potent antioxidant activity in the 2,2-diphenyl-1-picrylhydrazyl (DPPH) and ferric thiocyanate (FTC) methods. After adding synthetic and natural antioxidants in oil, Peroxide, p-Anisidine, Thiobarbituric acid value, Conjugated dienes, trienes and free fatty acids content were measured every 4 days. Acetone pod coat extract (2000ppm) of pigeon pea gave strong antioxidant efficacy in stabilization of crude soybean oil and hence could be recommended as natural antioxidants for food applications.The research explored the possibility of using pod coat of pigeon pea as imminent sources of green antioxidants and to evaluate their efficacy in stabilization of crude soybean oil.

Sugar beet is one of the sugar crops which widely grown in different regions of the world due to its advantages over Sugarcane. Several studies were conducted in Sudan to assess its adaptation and economic value. However, the aim of this experiment was to study the effect of application of compost and different levels of phosphorus fertilizer and their combination on Sugar beet (Beta vulgaris) growth attributes, yield and yield components. The study was conducted during the winter season 2018 –2019 at the farm of the College of Agriculture, University of Bahri, Alkadaro-Khartoum State, Sudan. The experiment was arranged in Randomized Complete Block Design (RCBD) with three replications and six treatments, namely the Compost (5t./ha.), Phosphorous (P2O5) (88kg./ha.), P2O5 (176 kg./ha.), Compost (5t./ha.)+P2O5 (88kg./ha.), Compost (5t./ha.)+ P2O5 (176Kg./ha.) and the Control (C) respectively. All cultural practices were carried out timely according to the recommendations of the Agricultural Research Centre in Sudan. Then the data pertaining the following agronomic traits were recorded, the leaf number; leaf dry weight (g), leaf area index (LAI) (cm), root diameter (RD) (cm) and root fresh weight (RFW) (g). The results of statistical analysis revealed the application of compost in combination with phosphorus displayed significant increase at 5% level for the leaf number (22.75), leaf area index (5.23), leaf dry weight(36.78), root diameter(69.67) and root fresh weight (422.68), followed by the application of compost alone compared to the control and other treatments. The study concludes that the combination of compost and mineral fertilizer (P2O5) proved to increase all Sugar beet growth and yield parameters.

Despite the existing several Sugar manufacturing companies in Sudan, there is an acute shortage in sugar supply, therefore the government imports Sugar to bridge the gap. One of the strategies to be followed is the introduction of Sugar beet (Beta vulgaris) crop, mainly for sugar production. This crop has several advantages over Sugarcane such as short duration, less water requirement, in addition to other uses like animal feed. Therefore it became necessary to have good understanding of agricultural operations, cultural practices and adaptation. However, the main objective of this study was to assess the effect of Nitrogen fertilizer and plant spacing on vegetative growth of Sugar beet. This study was conducted at the farm of the College of Agriculture, University of Bahri, Alkadro, Khartoum State-Sudan; during the season 2016/2017. The experiment was arranged in Split plot in Randomized Complete Block Design with six treatments and four replications. Two plant spacing (15 and 20 cm.) were used as main plot, referred as (S1, S2) along with three levels of Nitrogen fertilizer (40, 80 and 120 kg/ha.), as subplot; referred as (N1, N2 and N3) and the control (0). Data regarding leaf number, leaf area index (LAI), leaf dry weight (g) (LDW), root diameter (mm.) and root fresh weight were recorded and statistically analyzed. The results showed S2 (20 cm) increased all the studied plant characters, namely the leaf number (29.139), leaf area index by (7.54), leaf dry weight (g) to (89.870), root diameter (mm) (94,992), root fresh weight (g) (695.80) compared to S1(1015 cm). On the other hand; the application of N3 (120 kg/ha.) increased the lead number (30.956), leaf Area Index (8.841), Leaf dry weight (102.47), root diameter (97.955) and root fresh weight (851.77) compared to S2 and S1 as presented in (table 4, table 5 and table 6).

The number of children with SEN is continuously growing, leading to pressure on the few special schools available in the USA. Furthermore, the adoption of a special school system has been criticized on the basis that it isolates and discriminates against children with special educational needs and disabilities. Even though inclusive education can address such limitations, the application of the most appropriate pedagogical approaches for SEN learners is still a challenge. The presented study focused on critically appraising the pedagogical approaches for SEN learners in the 21st century and beyond. In order to achieve this goal, a systematic review of the literature approach was adopted. The literature search process was conducted on three databases: Education Full Text, Linguistics and Language Behavior Abstracts, and PsycINFO. The selection of these databases was influenced by their reputation of hosting high quality and up-to-date literature about special education. The initial literature search process generated 6129 hits, but only ten studies were finally selected for review after the application of inclusion and exclusion criteria. A critical review of the evidence presented in the selected studies generated eight themes describing various pedagogical approaches for special education, within both blended and mainstream learning environment. Knowledge generated in this systematic review can be used by the special education sector of the U.S to develop pedagogical approaches for SEN students, leading to improved performance and social skill development.

African bollwormis a worldwide-spread species that shows a high degree of polyphagia and it is considered as one of the main agricultural pests in the world. Laboratory experiments were conducted in the Research Laboratory, College of Agricultural Studies, Sudan University of Science and Technology to evaluate the lethal effect of C. rotundusand D. stramonium on the H. armigeraand to investigate the synergistic effect of sesame oil and tested extracts by dipping methods. Five concentrations (4%, 6%, 8%, 10% and 12%) were used for each plant extract in a Completely Randomized Design. Tubers ethanolic extract of C. rotundus at 12% concentration caused 90% mortality after 72 hrs of application, whereas 12% concentration of seeds ethanolic extract of D. stramonium generate only 70% mortality after 72 hrs of exposure. When sesame oil was added to each concentration of ethanolic extract of C. rotundus and D. stramonium it exhibited a synergistic effect. In fact, the 10% concentration scored 53.3% and 76.7% mortality, however, when mixed with sesame oil the mortality increased significantly to 83.3% and 100% for D. stramonium and C. rotundus respectively after 72 hrs of exposure. This study clearly demonstrates that both tested plants have a lethal effect on the larvae of the African bollworm. However, tubers ethanolic extract of C. rotundus seems to be significantly more toxic than the seeds ethanolic extract of D. stramonium. This study also revealed that sesame oil has a synergistic effect when added to these plant extracts.

The paper describes the development of a long-lasting product for Intra-domicile residual spray (IRS) and shows it is possible to obtain a residual effect of nearly 2 years. However, to obtain that the methods currently recommended by WHO for laboratory evaluation had to be modified and approached methods closer to the semi-field and field evaluations as applied in later phases of WHO procedures. Surfaces with high pH resulted in short residual effect unless the formulations were mixed with a silicone coating. Screening in huts constructed for the purpose was realised by dividing the wall surfaces in 25 test plots of 0.5 m² where formulations were applied randomly with more repeats the closer to the final formulation. Mud and concrete surface were more challenging than wood surface and stones and these could be dropped for screening. Wall surfaces heated by sun were repellent to non-blood fed mosquitoes, and the test in huts were limited to the mornings. However, blood fed mosquitoes were not repelled. Cone tests on mud-walls are complicated by the uneven structure of the surface and a better way of attaching cones to avoid mortality errors was developed. Formulations that can be applied and last for two mosquito seasons produce big cost savings for IRS programs, since program costs are mostly application costs.

Because of the ongoing Covid-19 crisis, supply chain management performance seems to be struggling. The purpose of this paper is to examine a variety of critical factors related to the application of contingency theory to determine its feasibility in preventing future supply chain bottlenecks. The study reviewed current online news reports, previous research on contingency theory, as well as strategic and structural contingency theories. This paper also systematically reviewed several global supply chain management and strategic decision-making studies in an effort to promote a new strategy. The findings indicated that the need for mass production of products within the United States, as well as within trading partners, is necessary to prevent additional Covid-19 related supply chain gaps. The paper noted that in many instances, the United States has become dependent on foreign products, where the prevention of future supply chain gaps requires the United States restore its manufacturing prowess.

The current uncontrollable outbreak of novel coronavirus (COVID-19) has unleashed severe global consequences in all aspects of life and society, bringing the whole world to a complete halt and has modeled significant threats to the global economy. The COVID-19 infection manifests with flu-like symptoms such as cough, cold, and fever resulting in acute respiratory distress syndrome (ARDS), lung dysfunction, and other systemic complications in critical patients are creating panic across the globe. However, the licensed vaccine has started to show up; some resulted in side effects that would limit its possibility in some circumstances as allergic personnel, for example. Moreover, the production and approval of new drugs is a very complicated process and takes a long time. On the other hand, stem cells have gone the extra mile and intensively investigated at preclinical and clinical studies in various degenerative diseases, including infectious ones. Stem cells are proposed as a broad-spectrum therapeutic agent, which may suppress the exaggerated immune response and promote endogenous repair by enhancing COVID-19 infected lung microenvironment. Also, stem cells have different application manners, either direct transplantation, exosome transplantation, or drug delivery of specific cytokines or nanoparticles with antiviral property by engineering stem cells. This review discusses and summarizes the possible emerging role of cell-based therapy, especially stem cell therapy, as an alternative promising therapeutic option for the treatment and control of novel COVID-19 and its potential role in tissue rejuvenation after COVID-19 infection.

Currently, many educational practitioners do not agree on how flipped classroom affects students’ learning effect. In order to further explore the impact of flipped classroom on students’ learning effect, this paper conducts a quantitative analysis of some flipped classroom experimental and quasi-experimental studies systematically by means of meta-analysis method. The study finds that the random effect model shows that the combined effect is 0.373, reaching the statistical significance level, which indicates that flipped classroom has moderate positive effect on improving students' learning effect. There is no significant difference in the effect of flipped classroom on the learning effect of different subjects and stages, but the effect on primary school students is weaker. Significant differences in the effect on learning outcomes among different knowledge types have been found, and specifically, the flipped instruction is good for the study of practical knowledge, but has less influence on theoretical knowledge learning. Therefore, in the application of flipped classroom, it is necessary to pay attention to the characteristics of different learning objects and types of knowledge, and flipped classroom teaching cannot be used too much in primary school and the teaching of theoretical knowledge during the coronavirus disease 2019 epidemic.

Today; there is an increasing demand for fertilizers due to the intensive and extensive agricultural activity to meet the ever increasing demand for food and fiber by the rapid world population expansion. This study is mainly concern with the Bat Guano which is usually collected from the Caves. This experiment was conducted at the Farm of the College of Agriculture, University of Bahri, Alkadaro, Khartoum North-Sudan during the period from July to November, 2017 with the objective to investigate the efficacy of Bat Guano and Nitrogen fertilizer on growth and yield of Serena and Opera (Helianthusannus, L.) Hybrid Sunflower cultivars. The study was based on split-plot experiment in randomized complete block design (RCBD) with four (4) replications. Data pertaining Plant Height (cm), Leaf Number (LN), Leaf Area (LA), Leaf Area Index (LAI) and Seed Weight (SW) were studied. The said data were analyzed using Statistic 8- software. The results reflected significant increase in plant height (F= 6.05, P < 0.0001, leaf number (F=2.37, P<0.0388), leaf area (F= 7.44, P<0.001), leaf area index (F= 6.53, P < 0.0001) and seed weight of both Sunflower cultivars respectively due to application of Guano and Nitrogen fertilizer compared to the control. It also reflected non-significant difference between all studied traits as application of either Guano or Nitrogen fertilizer. Moreover, all studied characters of the two cultivars have similarly responded to the application of the two types of fertilizers. Further studies are recommended to assess the benefits from the use of Bat Guano as a fertilizer.

This article has been retracted on March 01, 2021. VIEW THE RETRACTION NOTICE (https://openaccesspub.org/jsce/article/2243) Background Apis Mellifera L venom (Honeybees) is potent and safe anticancer drug. The present case is Basal Cell Carcinoma (SBCC), recurrent and invasde the skin of head (upper right, in front of the right ear). The patient was 65 years old in time of first intervention and the origin of BCC was primarily seen as abnormal growths and changes in birth mole on right side of head. Materials & Methods Preparation Bee Venom solution: Bee venom powder (crude) of dose 1gm was dissolved in 1000 ml of sterile distilled water then filtered by 0.22 micron syring filter. That final concentration of the stock bee venom become 1 ug /ml (i.e. 1ul=1 ug), and kept at -20◦C. (1mg (dried BV) + 1ml (water) = Final concentration (1ug/1 ul)). Before this novel intervention, allergy test performed by subcutaneous injection of small dose of bee venom (0.1 ml) and wait for at least one hour. The patient was not hypersensitive to honeybees’ venom. First stage of treatment: 1- Syringe of 1ml volume was used for direct local injection of cancer area by 0.3 ml from prepared Honeybees venom (0.1 % conc.). 2- At the same time, subcutaneous injection of 0.5 ml of bee venom solution infiltrated around the affected ear. 3- Topical application of the bee venom ointment 2% (bee venom in Vaseline) inside affected ear to protect the ear drum. This process repeated daily with cleaning of the ear every time by suitable safe and sterile saline solutions. 2nd stage: daily S/C injection in axillary area upper lymph nodes of 0.3 ml / bee venom ‘total doses 0.6 ml BV’ (left & right). 3rd stage: bee venom dissolved in sterile Clove oil was applied on inner ear above the drum. 4th stage: Management of healing process was enhanced by ascorbic acid solution as topical application on dead cancer cells and to help in removal of exudates and debris. Results The complete removal of malignant growths in affected ear achieved after 1 month from first bee venom injections. However; the cancerous areas under the second surgical intervention were treated during the next month. Conclusions Apis Mellifera L venom as anticancer drug is totally different from using direct stings as a method of Apitherapy, that because collection of bee venom lead to evaporating of most allergic substance that present in bees stings, also it can be used per os in people who exhibit different degrees of allergy against the drug safely.

Africa Region has the highest burden of malaria with an estimated of 3.5 million more malaria cases in 2017 compared 212 million cases in reported in 2016. Data collected from 2015 to 2017, shown no global progress in reducing malaria cases. In Mainland Tanzania, malaria control interventions have significantly led to the reduction in malaria prevalence from 18.1% in 2008 to 7.3% in 2017. Despite of these achievements, malaria burden is still highly heterogonous with some regions including urban peripheral areas of Dar es Salaam, presenting persistent malaria transmission ranging from 2 to 57%. Material and Methods A cross- sectional population based survey was carried out in Ilala Municipality in Dar es Salaam; data was collected from 2nd to 31 April, 2019. Multistage cluster sampling was used to select the households where individual member were conveniently selected to participate in the study. Structured questionnaire were administered by the trained researcher assistants to assess individual risk factors for malaria. Rapid Malaria diagnostic test (mRDT) was used to identify individual exposed to malaria infection. Measure of association used was prevalence odds ratio (POR). Multivariate regression model used to determine prevalence odds ratio, variable with p- value < 0.05 were considered as independent risk factor for persistent malaria transmission. Results A total of 830 participants were recruited in the study, mean age was 24yrs ±20.4SD. Majority 489 (58.9%) were female, 459 (55.3%) were >18 yrs old, primary or no education were 687 (82.8%), farmer or unemployed were 639 (77%). Msongola ward contributed 406 (48.9%). Overall malaria prevalence in the study areas was (4.5%). Nets ownership was 141 (16.9%), usage was 121 (85.8%).Low proportion of net ownerships (POR: 7.67, 95% CI: 4.23, 24.6), residing in the households surrounded by mosquito breeding sites POR: 20.07, 95% CI: 7.03, 57.29) and residing in houses with unscreened windows (POR: 1.21, 95% CI: 1.26, 3.40) were independently associated with malaria infection. Conclusion Low nets ownership, residing in the households surrounded by mosquito breeding sites and in households with unscreened windows was independent factors associated with risk of malaria in the areas. Promotion of ITNs coverage, application of biolarvicides through community engagement and house screening was recommended to reduce the risk of malaria infection in the areas.

Testing people for COVID-19 in a country like India with a huge population is a near impossible task therefore the government is using body temperature as a testing parameter to cover the whole population. Infrared thermometers are used to find the temperature because it is a cheaper and faster way. This testing rate can be done even faster, without the need of manpower and with far more accuracy using smart watches and bands. These wrist-wearables are mostly used for fitness purposes which have more measuring equipment that is used for preliminary testing done for COVID. This equipment’s are in the form of electric sensors which are small enough to be used in wearables. So we can get even more insight and accuracy compared to the standard method. In this study an application is created to use an array of sensors (Pulse sensor, Pulse oximeter, Accelerometer and temperature sensor) are being used in these wearables to find the chance, that a person is affected due to COVID-19 and the information can be seen real time in mobile phone through the application. All the information can be sent to the health organization’s if required.

We investigated physical steric and thermal stability effects induced by cholesterol and polyethylene glycol (PEG) in liposomes encapsulated with riboflavin. The composition of liposome was varied systematically to decipher the individual and combined effects of cholesterol and PEG on the stabilization of liposomes, specially the photopolymerizable liposomes for their potential applications in photo-treatments. Our results indicate that inclusion of PEG in the lipids enhances the steric stabilization by adopting a brush-like regime that prevents the agglomeration of encapsulated liposomes. A mechanistic differential scanning calorimetry studies reveal the phase transitions and enthalpy changes in the lipid bilayer due to the presence of cholesterol suggesting its role in regulating membrane fluidity. Supporting in- vitro studies confirm the efficacy of PEGylated formulations encapsulating riboflavin.

Zooplankton production and growth performance of post-larvae of common carp according to the level and frequency of fertilization with chicken droppings were studied between May and October 2017 at the IRAD pisciculture station in Foumban. To this end, two doses of hen droppings, namely 450 g/m3 (D450) and 600 g/m3 (D600), were each applied at two application frequencies (weekly (F2) and bimonthly (F1)). Thus, 1200 post-carp larvae were distributed in 12 identical concrete tanks (1.2m x 0.75m x 1m) each filled with 400 liters of water. The 2 doses applied at 2 frequencies were applied randomly in the 12 tanks in a complete random device comprising 3 treatments and 2 repetitions. Six days after fertilization, each tank was sown with zooplankton at a density of 7 individuals per liter (ind/l). The loading was carried out 12 days after fertilization at a density of 100 ind/m2. The results show that regardless of the dose and the frequency of droppings applied, the production of zooplankton was optimal 10 to 12 days after fertilization. Considering the growth performance, the tanks receiving the 600 g/m3 dose every 2 weeks presented the highest significant values (p <0.05). On the other hand, the survival rate (36% on average) was not significantly influenced (p˃0.05) by the dose and the frequency of fertilization. The 600 g/m3 dose applied every two weeks can be recommended for the rearing of post-larvae common carp.

In the last decade, the amount of collected data, in various computer science applications, has grown considerably. These large volumes of data need to be analysed in order to extract useful hidden knowledge. This work focuses on association rule extraction. This technique is one of the most popular in data mining. Nevertheless, the number of extracted association rules is often very high, and many of them are redundant. In this paper, we propose an algorithm, for mining closed itemsets, with the construction of an it-tree. This algorithm is compared with the DCI (direct counting & intersect) algorithm based on min support and computing time. CHARM is not memery-efficient. It needs to store all closed itemsets in the memory. The lower min-sup is, the more frequent closed itemsets there are so that the amounts of memory used by CHARM are increasing.

The passage of the posterior tibial nerve in the tarsal tunnel has a great clinical significance, thus detailed anatomical knowledge is mandatory for safe clinical intervention. This study was to identify the morphological appearance of the tibial nerve and its bifurcation. Sixty lower limbs of formalin embalmed cadavers were randomly selected. Data were collected through the application of standard dissection method of the tarsal tunnel of lower limbs (30 rights and 30 left) of formalin embalmed cadavers. The posterior tibial nerve and its branches were exposed from the distal end of the leg toward plantar surface beyond its bifurcation by resecting the skin and flexor retinaculum. The study triggered several findings: The posterior tibial nerve is flattened shaped in 21 specimens 70% and has a rounded shape in 9 specimens 30%in the right foot. In the left foot it is flattened in 17 specimens 56.7% and rounded shape in 13 specimens 43.3%. Posterior tibial nerve bifurcates into medial and lateral planter nerves inside tarsal tunnel in 20 specimens 66.7% in the right foot and in 21 specimens 70% in the left foot. This study concludes that posterior tibial nerve commonly has flattened shape and divided into medial and lateral planter nerves inside tarsal tunnel.

A field experiment was conducted during 2017/2018 to assess the effects of Argel (Solenostemmaargel, Del. Hayne) and Nitrogen fertilizer on the performance of two Sunflower Hybrid cultivars, with the objectives to exploit an easy, economic, and accessible organic fertilizer, the Argel in the phase of the continuous increasing prices of chemical fertilizers.. This experiment was laid out on spilt-split-plot experiment in Randomized Complete Block Design (RCBD) with four replications. Observations were taken on some agronomic traits (Plant height (m), Leaf area (LA), leaf Number (NL), Leaf Area Index (LAI) and Mean Seed Weight). The results revealed that the application of Argel and Nitrogen fertilizer have significantly increased the leaf Area (F= 7.22, P < 0.001), Plant Height (F=2.68, P < 0.2001), Leaf Number (F= 3.90, P < 0.0024), Leaf Area Index (F= 3.83, P < 0.0026) and Mean Seed Weight of both Serena and Opera cultivars respectively compared to the control. However, the different treatments of Argel and Nitrogen reflected variable degree of increase for the studied parameters. The study concludes that Argel is very promising, therefore a further study with different levels of Argel including other plant parameters is recommended.

This research paper focuses on rainfall variations in Tamil Nadu, India using Wavelet, Linear regression and Artificial Neural Networks model from 2004 to 2017. As the rainfall is the key factor in understanding climate change, the seasonal datasets from 2004-2017 of Tamil Nadu state has been taken for study. The salient feature of this study is the application of Neural Networks and wavelet analysis. It reveals that the rainfall variations are ambiguous that it does not maintain a constant pattern. Wavelet coefficients of multiresolution spectrogram reveals that the intensity of rainfall in each year. Linear regression model divulge the pattern of rainfall followed in every season and the results show that except winter season all other season suffers deficient rainfall. The deficiency of rainfall may be due to different parameters like ElNino or LaNina pattern or global warming. Results showed that all seasons except winter does not maintain consistency in the rainfall variability. Winter season provides the positive slope values of 4.7 and 0.6 for January and February respectively. Moreover Artificial Neural Networks training provides prominent results of Regression value 0.98 which is comparably high with other seasons taken for study.

Immune thrombocytopenia currently called under its’ new name, immune thrombocytopenic purpura (ITP) is a disease characterized by thrombocytopenia, in which the body attacks its own platelets due to the disorders in immune system. The pathophysiology of this disease includes increased platelet destruction and most megakaryocyte production in bone marrow. The most common clinical manifestation of ITP is mild or severe progressive bleeding that could result in death. ITP is generally named as primary or secondary ITP according to thrombocytopenia severity, disease duration, bleeding status and secondary occurrence of the disease. Currently for diagnosis, despite the blood count, antiglobulin test and laboratory tests that can detect platelet-bound antibodies, they are not enough for definitive diagnosis. Like the difficulty in diagnosis, ITP treatment is quite complicated which varies depending on age, characteristics and risk of the patient. It is classified as first, second and third-line treatment options. Also, depending on the condition of patients, combined treatment might be an option which increases the complexity of the treatment. Unfortunately, discussions related to different clinical applications in diagnosis and treatments continue recently. For this reason, we considered that preparation of a review containing recent updates in diagnostic approaches and treatment options in ITP will be remarkable and beneficial for physicians interested in this subject.

The fruit flies of familyTephritidae are considered as serious pests of Mango in Sudan. They cause substantial damage to Mango in all Mango production areas. The application of various pesticides appeared to be ineffective. Therefore, this study was carried out to investigate the efficacy of Spinosad as new promising control measure to the fruit flies. This study was carried out at Shendi area, River Nile State during the period from April 2012 to August 2014, where Pheromone and food bait traps were used for detection and monitoring the fruit flies species in the study area. Spinosad (0.24g\L) was applied as a partial spraying pesticide. Results indicated that; the application of Spinosad highly decreased the fruit flies numbers. The average number of fruit flies collected in April was (947.22 and 1001.67) for the treated and untreated orchards respectively. The numbers of fruit flies in the treated orchards had decreased gradually during May, June, July and August, 904.7, 760.22, 609.6 and 452.7, respectively, but in untreated orchards for the same months had increased to 1003.67, 1103.67, 1336.67and 1468.67 respectively. However, the infestation level in mango fruits in the treated orchards was found to be 2% compared with 64% for untreated one.

In the country, food production is more compromised every day, despite zero efforts and government, agricultural and livestock sector, causing poverty, migration, marginalization among other social disorders in addition to food insecurity. In Mexico 34% of the population is engaged in agricultural tasks, with very small land areas. The fact that 85% of do not have more than 5 ha of arable land, and that among them, 90% do not reach 3 ha clearly indicates their great need for light machinery .The solution to these problems family farmers are provided with affordable technologies to increase their productivity. One of the most common problems in agriculture is the application of agrochemicals, which is tedious and dangerous when farmers are exposed to these highly toxic products, therefore a system is proposed is through the help of a drone or remote control helicopter, both of economic type connected by a hose to the sprinkler and a tank. Due to the danger of applying agrochemicals for family farmers who rarely follow the precautions to apply these products, the proposed alternative is attractive for small agricultural properties, although it is not free of cost, the drone and the optimal sprayer should be investigated.

Nanocomposites are worn resistant materials used in cutting tool applications. The materials are composed of ultrafine powder hard phase grains surrounded by a tough binder phase carbon nanotubes (Mo2C)1-x–(TiC)x (2≤x≤4)//1Wt% SWCNTs. Composite bicarbide Mo2C-TiC was rapidly synthesised and simultaneously consolidated by field activated sintering technique (spark plasma sintering) at which the extensive volume expansion occurred as a function of the volumic fraction from 20 to 40 vol.% of TiC powders and 1 Wt.% of SWCNTs was reinforcement of the NCMC’s. The sintered powder mixture was examined by XRD patterns, the morphology of the obtained phase was observed by SEM and the phase compositions in different regions were analyzed by EDX. The composites were processed using Field Activated Sintering Technique, spark plasma sintering (SPS) at temperatures in the range of 1700-1800°C with addicting of SWCNTs. The effects of SWCNTs addition on phases morphology, microstructure hardness and fracture toughness of the nanocomposite were investigated. The best product contained 1.0 Wt% SWCNTs from (Mo2C)1-x–(TiC)x , x= 0.2 which was sintered at 1700°C, 70 MPa for 10 min, M0.8T0.2/ 1 Wt% SWCNTs exhibit a better density, highest hardness and good ductility. Relative densification was achieved 99.5 % from the theoretical and good mechanical properties like hardness and fracture toughness (KIC=5.6 Mpa m1/2) are improved. The results were confirmed using Raman scattering resonant spectroscopy.

In spite of the popularity of open-air waste dumping in Nigeria, it remains a relatively less effective waste management option across the globe because of its associated environmental impacts which includes the release of green house gases (GHGs), persistent organic pollutants (POPs), and metal micro-pollutants amongst others. This study aims to assess the potential environmental risks associated to metals released and vertically delineated across the soil profile within surroundings of dumpsite. Heavy metals in soil samples were acid-digested using the aqua-regia mixture of hydrochloric and nitric acid, followed by instrumentation analysis using the GBC 908 PBMT model atomic absorption spectrophotometer. Contaminated sites showed metal concentrations ranging from 1.493 to 109.460 mg/kg, 0.133 to 4.237 mg/kg, and 5.200 to 25.367 mg/kg for lead, cadmium and chromium respectively, with location 1 land area showing the most contamination. Only soil chromium was observed within regulatory stipulations in all cases. There was significant variation (p < 0.05) between the different sample locations, thereby indicating variations in composition of dumped wastes. Lead and cadmium showed the strongest positive correlation (r = 0.855, p < 0.01) and the application of some heavy metal pollution indicators revealed relatively higher metal loads and degree of contamination, as well as depicting potential ecological risk for soils of location 1. The significant heavy metal contamination of soils in the Tombia-Amassoma waste dumpsite requires that the local environmental sanitation and regulatory authorities take necessary remedial action to forestall the escalation of public health concerns that may emanate from this open-air dump.

Pharmacodynamic modeling of sunscreens was performed using a new concept of Skin UV Index (SUI) on the exposed skin as a parameter to evaluate the potential effectiveness of sunscreens against sun damage. The SUI predicts the UV heat intensity on the skin surface in terms of the solar UV Index at the time of the study and is calculated by solar UV Index/sunscreen’s SPF. SUI numbers for sunscreen with SPF ranging from 2 to 100 under a solar UV Index of 10 was used for illustration. Based on guidelines from WHO, Australia and New Zealand, sunscreens yielding SUI < 3 are assumed to be effective against sun damage such as sunburn and melanoma. Based on the above assumption, sunscreens with SPF > 4 were found to be effective when sunscreens were evenly applied at 2 mg/cm2. Review of numerous studies suggests that missing applications may represent a major, seemingly unavoidable, SPF-independent factor causing unintended sunburns for sunbathers in the US and other countries with a temperate climate. This might in turn become a major factor for causing exponential increase in melanoma incidence rates observed in the last few decades. For example, in an SPF 30 sunscreen study all 25 participants suffered unintended sunburns after one week of sunbathing. Also, a mean missing application of 20% of the total exposed area and a mean missing of about 50% of the time were reported in two separate studies. Simulations were also performed with under-applications of 50% and 75%. The present simulations may provide a rationale of why routine use of a low SPF 8 sunscreen was reported to be effective against melanoma in a 2018 Australian study. Based on model simulations it is proposed that in the US, SPF 8 sunscreen and SPF 2 to 6 sunscreen may be adequate for routine, unintentional use for sun-sensitive populations and non-sun-sensitive populations, respectively.

The aim of this physical anthropometric study is to determine sex by foot measurements. Dismembered human remains are frequently found in cases of mass disasters and criminal mutilation. It is therefore of interest to use foot dimensions for the determination of sex (gender) of an individual in order to assist in establishing personal identity. Another application of anthropometrical measurement is in ergonomics which is the design of working space and the development of industrialized products such as furnishing, cars, tools, shoe designing etc. 500 adult subjects(250 males, 250 females)aged 18-50 years without any foot disability within Ogbomosho North Local Government, Oyo State were randomly selected for the study. The males had an average foot length about 1cm greater than females and foot breadth in males was about 1cm greater as compared to females. Difference in foot length and foot breadth in males and females of the population was highly significant. With the statistical analysis, any foot with length lesser than 26cm and breadth lesser than 11cm can be suggested to be that of a female while any foot with length greater than 26cm and breadth greater than 11cm can be suggested to be that of a male. Therefore, 26cm can be taken as the cut-off point for foot length and 11cm as the cut-off point for foot breadth in this locality.

In this study, a peroxidase from new source was purified using ion exchange and gel filtration techniques. The recovery for peroxidase activity was 19% with 11-fold purification and specific activity of 749 unit/mg protein. Purified peroxidase demonstrated a molecular mass of 39 kDa using gel filtration and was confirmed as a single band on SDS-PAGE. The purified peroxidase revealed a broad optimum pH activity at 6.0-6.5 and 50°C temperature. The kinetic parameters for purified peroxidase toward H2O2 and guaiacol as substrates were found to be Km = 3.355, 5.395 mM, Kcat = 99.52, 79.56 s-1 and Vmax =1.531, 1.242 µmole ml-1 min-1, respectively. The catalytic efficiency (kcat/Km) of the purified peroxidase was 14.75 and 29.66 s−1 mM−1 for guaiacol and H2O2, respectively. Peroxidase activity was observed to be enhanced by Cu2+, Co2+, Ni2+ and inhibited in the presence of Sn2+, Al3+, Hg2+, NaN3, EDTA and urea. Characterization showed that peroxidase purified from C. forskohlii has the ability to be used for food industrial applications.

Prostate specific antigen (PSA) does not provide the high reliability and precision that is required for an accurate screening for prostate cancer (PCa). The aim of our study was to search for a simple, rapid, direct, preferably non-invasive, and highly accurate biomarker and procedure for the screening for PCa. For this purpose the levels of bromine (Br) and zinc (Zn) were prospectively evaluated in expressed prostatic fluid (EPF). Also Zn/Br concentration ratio was calculated for EPF samples, obtained from 38 apparently healthy males and from 33, 51, and 24 patients with chronic prostatitis (CP), benign prostatic hyperplasia (BPH) and PCa, respectively. Measurements were performed using an application of energy dispersive X-ray fluorescent (EDXRF) microanalysis developed by us. It was found that in the EPF of cancerous prostates the levels of Zn and Zn/Br were significantly lower in comparison with those in the EPF of normal, inflamed, and hyperplastic prostates. It was shown that “Sensitivity”, “Specificity” and “Accuracy” of PCa identification using the Zn and Zn/Br levels in the EPF samples were all significantly higher than those resulting from of PSA tests in blood serum. It was concluded that the Zn and Zn/Br levels in EPF, obtained by EDXRF, is a fast, reliable, and non-invasive diagnostic tool that can be successfully used by local, non-urologist physicians at the point-of-care to provide a highly effective PCa screening and as an additional confirmatory test before a prostate gland biopsy.

Trichoderma reeseiβ-glucosidase (Bgl1) is one of four enzymes demonstrated to act synergistically to degrade cellulose both in vitro and in vivo. Our work attempted to better understand the substrate specificity and potential biotechnological applications of Bgl1. T. reesei Bgl1H cleaves over 80% of the β-(1-4) and β-(1-3) linkages in β-glucan and 14% of the β-(1-4) linkages in amorphous cellulose, significantly more than any tested bacterial β-glucosidase. Bgl1H cleaves 50% of the β-(1-4) linkages in xyloglucan when supplemented with cellulase and α-xyloside. Approximately 20% conversion to glucose was obtained from insoluble β-(1,3)-linked curdlan using only Bgl1H; addition of a curdlanase resulted in conversion of approximately 70% of the curdlan to glucose. Bgl1H also produces xylose from xylooligosaccharides and debranched xylans. For both glucans and xylans, the relative rates of hydrolysis increase with increasing polysaccharide chain lengths. Bgl1H is able to partially degrade β-glucan in a variety of grain components; addition of endo-acting enzymes improved the enzyme’s performance on these grain components. The ability of this enzyme to produce monosaccharides from undigestible polysaccharides suggest it may have potential in improving utilization of carbohydrates in animal feed, fermentations, and other biotechnological applications.

Aim To study the chondroplasty efficacy of the bone matrix obtained using an original technology in restoring cartilage defect of the knee joint. Material and Methods Marginal defects were modeled on the surface of the distal end of the femur in 40 adult male Wistar rats. The bone matrix obtained using an original technology was implanted in the damaged area in animals of the experimental group. Material was investigated by means of light microscopy, transmission and scanning electron microscopy, and electron probe X-ray microanalysis. Results It was found that the bone matrix implanted did not cause an immune rejection reaction, activated reparative chondrogenesis for a prolonged period. In the area of articular cartilage lesion, the regenerate acquiring cellular and histochemical characteristics of the hyaline cartilage tissue was formed. The chondroinductive properties for the bone matrix were ensured by localized growth factors and morphogenetic proteins released during osteoclastic resorption. Conclusion The application of the bone matrix as a stimulator of chondrogenesis is theoretically reasonable and has a good perspective in treatment of damages and diseases of the articular cartilage.

The agronomic management of symbiotic (S) inoculations, by means of bio-fertilizers (BF), is aimed at inducing modifications of the plant rhizosphere and thereafter of the phenotype and yield of the crop. It is here shown that the yield response of maize to a symbiotic treatment may be correlated to six easy-to-calculate indicator variables on the basis of the raw foliar pH, NIR-Spectroscopy of leaves, and the NIRS of hay litter-bags from soils. It has been confirmed, in a set of thirteen pairwise comparisons of Symbiotic (S) soil inoculated by BF vs. Control (non-inoculated soil; C), that the inoculation on average acidified the leaves by -3.7% pH units (P<0.0001). The responses in yield ranged from +25.2% to -9.2% (av.ge +3.5%; P = 0.03), but with average null responses in two centers and a significant response (+11%) in a third center. NIR-Tomoscopy scans (No. 574) were also performed on the leaves, and in addition, hay-litter-bags that had previously been buried in fields were dug up after two months, and 431 NIR- scans were acquired. The effect-size on the yield was expressed as the logarithm of the response ratio, i.e. the mean of the inoculated Symbiotic treatment divided by the mean of the non-inoculated Control for each pairwise comparison. A multiple regression model was developed to predict the symbiotic response to the treatment using six independent variables, including the squared litter-bag fingerprints, and an R2adj. level of 0.78 (P=0.01) was reached, with a standard error of ±4%. Validation in one external maize field, with a positive response to bio-fertilizers, demonstrates the juxtaposition of the estimated and accomplished yield. In a second experiment, with 40 pairwise comparisons, the two tested maize varieties did not respond to five types of bio-fertilizer, and the negative results were predicted at 84% (P 0.0012). The soil biota is a key factor for the application of appropriate microbial inoculants in the field, but the genotype/genotype interactions between the microbial strain (s) and the crop cultivar (s) require prior screening to obtain the desired results.

The telomeres existing at the end of the eukaryotic chromosome, play an important role in localization, pairing of homologous chromosomes during cell division and synapsis formation, while telomerase is involved in maintenance of the telomere length. The application of antiHIV-1 molecules particularly NRTIs have been shown to interfere with telomerase function thereby inducing aging processes. Since the application of these molecules has already indicated production of oxidative stress and toxicity in AIDS patients, their adverse impact on telomerase function may further worsen the situation. In addition, the negative influence of antiHIV-1 regimens on certain host factors involved in telomerase function may enhance aging. HAART changes the landscape of the disease by progressively decreasing the progression of HIV-1, but exerts prolonged adverse effects on the telomerase function. Though there is no exact information available on this issue, intensive efforts are needed to explore regulation of telomerase expression in HIV infected individuals and particularly those receiving antiretrovirals.

Modern medicine gives treatment options even in cases, where this has not been possible in the past. We want to present how negative pressure wound therapy (NPWT) helps in limb salvage. The case report brings our insight and experience on how to be successful with NPWT. We present a high-energy injury with an open tibial fracture IIIB according to Gustillo-Anderson classification 11. NPWT is an excellent option to treat extensive soft tissue injury. NPWT is also beneficial in the application of the dermoepidermal graft as we have found. We can confirm that this therapy contributed to a faster healing of soft tissues compared to classical wound healing.

Triacontanol (TRIA) role in improving growth, physiological activities and tolerance against abiotic stresses has been reported. Yet, the mechanism by which TRIA executes its effects remains elusive. This work therefore studied the possible role of TRIA exogenous application in counteracting the adverse effects of nickel (Ni) treated maize seedlings. Maize seedlings (15-day-old) were grown in washed sand irrigated with nutrient solution provided with 100 μM NiCl2. Two concentrations of TRIA (25 and 50 µM) were applied twice as a foliar spray for Ni-stressed seedlings. Shoot and root growth attributes, Ni content, and antioxidant defence systems of maize seedlings were determined. Ni treatment reduced the shoot and root length and biomass, causing necrosis of the old leaves,greater reduction was shown in the roots. The shoot and root length was negatively correlated with their Ni content, which was consistent with their content of H2O2, but not with their malondialdehyde (MDA) content. As the roots had the greatest Ni content, maximum peroxidase (PX) and glutathione reductase (GR) activity as well as the highest ascorbic acid (ASA) and reduced glutathione (GSH) content were observed in the roots. The Ni-induced deleterious effects were alleviated by foliar application of TRIA concentrations. Also, TRIA treatment minimized root Ni content, whereas it maintained the shoots unharmed by Ni. Such mitigative effects of TRIA are explained by its key role in enhancing antioxidant capacity (expressed as IC50), increased PX and ascorbate oxidase (AO) activity, GSH, and total phenolic contents.
