Many people fear from COVID.19 vaccines, due to rapid production of it, that made them doubt about the value of its clinical trials. Individuals with chronic diseases, particularly renal patients, whom are not able to excrete exogenous estradiol in level, and high level of estradiol may activate coagulation system presence of high level of proinflammatory cytokines interlukein-6, which cause tissue injury, activation of thrombin and aggregation of platelets, and presence of factor XI in some types of COVID.19 Vaccine may lead to great risk of thrombosis, that may lead to deadly complications, certainly among women.

The article analyzes the species composition, number and ecological factors influencing the redistribution of birds in water bodies in different types of water basins of South-West Kizilkum and the seasonal dynamics of birds.

Objectives: This study was carried out for assessing total and available soil Cu in a Carixien soil series of a part of Burgundy, France. Method: Soil samples were collected from surface-ploughed layer in agricultural fields across the southern part of the Yonne district, Burgundy, France. The extraction time of soil Cu ranged from 5 minutes to 24 hours. Findings: The result on Carixien soil was Chaponne. And the trend of extraction on the Carixien soil was different from the results on Domerien soil. The pH value of the extracted solution increased for the Chaponne soil. For purpose of comparison it remained steady in the case of the Dubloc soil from the Domerien soil series, the copper (Cu) absorbance through the atomic absorption spectrophotometry and its content. The Cu concentration in the extracted solution increased up to the 24h-extraction (+ around 200 %) on the basis of 5 minutes. In the case of the Dubloc soil from the Domerien soil series, the Cu concentration in the soil extract only slightly increased during the 24h-extraction period (+ around 100%) on the basis of 5 minutes. Novelty: From these data it is considered that while Domerien soils have no ‘hole’ for Cu extraction, Chaponne soil has a ‘hole’ for Cu extraction.

Identifying the types of microscopic algae that are prevalent in water basins and studying their importance is one of the most pressing issues awaiting solution today. In this regard, research has been conducted to observe the classification of Lake Kara-Kyr in Bukhara region and the study of the types of microscopic algae in the water, the seasonal propagation. Commonly accepted algal methods and plant identifiers were used to determine the types of microscopic algae. According to the results, a total of 41 species belonging to the Chlorophyta division were identified in Kara-Kyr Lake. The seasonal propagation of the identified species was analyzed and 35 species were recorded in spring, 38 in summer, 28 in autumn, and 11 in winter.

Background: Schistosomiasis is one of the world's most prevalent parasitic infections, with at least 200 million people infected and about 700 million at risk in Africa, Asia, and South America. Although five species of waterborne trematodes in the genus Schistosoma are capable of causing human infection, the most important are S. haematobium & Schistosoma mansoni and the majority of cases occur in sub-Saharan Africa. Methods: A_comparative study aimed to compare between indirect-hemagglutination assay and Golden Stander Method which used for diagnosis of Schistosoma haematobium. Total of 73.0 samples were collected from people located in two villages in the areas of Sudan endemic with Schistosoma haematobium. The samples were analyzed by the centrifuged parasitological examination and indirecthemagglutination assay (IHA). Result: Statistical analysis of the results showed that the sensitivity value of the IHA test was 95.8% and specificity was 4.1%. Conclusion: A search for a good diagnostic test that can be applied in field situations in Sudan should be given high priority.

It is not easy to make a solution for coronavirus as soon as someone peels the banana skin and cover again the part to the banana. But it is necessary to think the procedure and to prepare the solution of this pandemic disease. The human-being invaded the realm of this wild animal. In this case, it is for the wild bat. It seems good to find the polluted condition for the wild bat. At first we do recover the original or optimum condition for the wild bat, it is necessary to prevent the possible continual occurrence of this disease. At the second part, the scientist might see the physiological change of the bat with the recovering the normal living condition of the wild bat, and then they can obtain possible viewpoint in order to prepare its vaccine. Experiment A: You will feed bats on polluted water. Experiment B : You will give the ill bat the normal water. Experiment C: In this process of the turning point from the disease to health condition of the diseased bat, you can observe and analyze the blood or urine or saliva in order to find the immune material and system.

Kenyan population mainly lives in rural underdeveloped areas spread across the country. Rural areas in Kenya is characterised by low formal employment, low income as well as high level of food insecurity which eventually leads to increased poverty levels. Rural folk considers indigenous chicken as key in economic empowerment and as part of the social life. Chicken provides cheap animal proteins especially white meat and eggs and contributes to convenient cash income. Chicken farming is easy to implement and carrying out feeding is indeed much easier than any other agricultural enterprise hence considered convenient to resource poor rural households. Chicken, especially indigenous are prevalent in the rural areas owing to increased adaptation to harsh scavenging conditions, survival in poor nutrition and tolerance to disease and parasite. Women being found in the homesteads more hours than male counterparts provides a biased operation of women carrying out the feeding operations more than male. This study therefore explains the gendered participation in feeding of chicken among the households in North Rift Region in Kenya. Since feeding is a crucial component in the chicken production value chain, it is important to involve all the players in the household to enable ownership and enhance the investment through chicken farming.
