Cell Therapy as an Alternative approach for COVID-19 Infection Consequences: A Non-Systematic Review

Abstract:

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 pr...

The Olive Quick Decline Syndrome: A Syndemic Outbreak in the Apulia Region, Southern Italy

Abstract:

Since a decade in Apulia, south-east of Italy, an increasing number of olive trees developed the quick decline syndrome (OQDS) leading to partial or total dessication of the canopy and subsequent death. Currently six million of olive trees show the symptoms of the decline, despite the mitigation measures which were undertaken to contrast the progression of the dessication. Associated with the syndrome, several phytopathogenic fungi were detected in the rhizosphere, endosphere and phyllosphere of the trees, along with the phytopathogenic bacterium Xylellafastidiosasubsp. pauca. Alongside, other pathogenic events were clearly identified, mostly defeating soil resilience: salinization, pollution, erosion, decline of biodiversity. Further events include delays in the adoption of appropriate mitigation measures not directed to challenge solely a bacterial pathogen, misuse of the territory, erratic agronomic management ...

Simulation of Groundwater Movement from Pits Fenced by Zchukovsky's Sprunts

Abstract:

The hydrodynamic production considers the filtration of liquid from the pits, fenced with spools of Zhchukovskiy, through a layer of soil, underrunable by a well-permeable pressure aquifer, on the roof of which contains an impenetrable area. To study infiltration on the free surface of groundwater, a mixed regional multi-parametric task of the theory of analytical functions is formulated, which is solved by the Semibarinova-Kochina method and methods of conformal display of areas of special species characteristic of the tasks of underground hydromechanics.

Mathematical Modeling of Covid-19

Abstract:

The novel coronavirus (COVID-19) suddenly appeared in Wuhan, Hubei since December 2019, and quickly swept across China, then the whole world. Today, after more than 100 days of fighting against the virus, China's epidemic has been effectively controlled, but when we looking at the entire world, the novel coronavirus has rampaged globally, especially in the United States and many European countries. This paper mainly studies the impact of COVID-19 outbreaks at Hubei Province and the United States, fits the given data and predicts future trends.

Proposition and Practical Significance of Two Classes of New Teaching Methods and Diversified Assessment During the Coronavirus Disease 2019 Epidemic

Abstract:

After entering the new century, people are facing a new external environment. Recently human society is coming into knowledge economy era, and the industrial structure has deeply been adjusted. Today, the past teaching method of imparting knowledge and getting people to accept education, or exam-oriented teaching ideas have been unable to keep up with the needs of the development of the Times. In the future, the key point of education is to promote people to understand the knowledge, and grasp rules between things. Based on this, it is particularly necessary for the talents cultivation to adopt a new idea of training. The paper takes the major in mathematics as an example, designs two classes of new teaching methods CT&CL and BOOF with the diversified assessment to cultivate students’ innovative thinking, providing a reference for the other students. The two classes of new teaching methods and the diversified assessment are worthy of further spreading and ex...

Statistical Analysis on the Influence of Flipped Classroom Teaching on Students’ Learning Effect During the Coronavirus Disease 2019 Epidemic

Abstract:

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 k...

Feasibility of Detecting Brain Areas Involved in Extreme Breath-Hold Diving

Abstract:

A feasibility study explores neuroimaging approaches to identify brain regions engaged during extreme breath‑hold diving. Methods, safety considerations, and preliminary activation patterns are summarized to motivate further controlled studies.

Conclusion from the Doctor's Dissertation Martynov V.L. on Surgical Correction of Digestive System Refluxes

Abstract:

Annotation On the basis of 40 years of work on the treatment of 415 patients with gastroenterocolitis clinic, the author revealed the presence of refluxes due to anatomical defects of the Bauhinia valve (its failure) and the duodenum (chronic duodenal obstruction) at all levels of the gastrointestinal tract. After surgical correction of these anatomical breakdowns, the author states a significant improvement in all indicators of the state of both the digestive system and some extraintestinal manifestations, possibly the onset of precancer. The results obtained allowed the author to conclude that there are no "functional" disorders, this is only the level of our knowledge. Operations have been developed to correct the failure of the Bauhinia flap, intraoperative prevention of refluxes, and indications for methods of correcting chronic disorders of duodenal patency.

Culture of Cyclops for Use the First Intermediate Host in Experimental life Cycle of SpirometraSpecies

Abstract:

In natural conditions Cyclops are the first intermediate hosts in the life cycle of Spirometra species. In this paper we describe simple method of culturing Copepod of the genus Cyclops for use the first intermediate host in experimental life cycle of Spirometra species.
