Analysis of COVID-19 Death Cases Using Machine Learning.

COVID-19 has threatened the existence of human life for more than the last 2 years. More than 460 million confirmed cases and 6 million deaths have been reported worldwide due to COVID-19. To measure the severity of the COVID-19, the mortality rate plays an important role.

Growth attributes, biochemical modulations, antioxidant enzymatic metabolism and yield in varieties for salinity tolerance.

Improvement in salinity tolerance of plants is of immense significance as salt stress particularly threatens the productivity of agricultural crops. This study was designed to assess the tolerance level of six varieties (Super, Sandal, Faisal, CON-111, AC Excel and Punjab) under different levels of salinity (0, 50, 100, 150 & 200 mM) with three replications under CRD. Salt induced osmotic stress curtailed the plant growth attributes, photosynthetic pigments and disturbed ionic homeostasis (K, Na, Ca Cl) but least disturbance as compared to control was found in Super and Sandal cultivars.

Characterization, the Antioxidant and Antimicrobial Activity of Exopolysaccharide Isolated from Poultry Origin Lactobacilli.

The natural antioxidant agent is urgently needed to prevent the negative effects of newly generated free radicals and chronic disorders. Recently, the microbial exopolysaccharide (EPS) is currently used as a potential biopolymer due to its unique biological characteristics. In this study, the biological potential was carried out on the EPSs produced by Lactobacillus reuteri SHA101 (EPS-lr) and Lactobacillus vaginalis SHA110 (EPS-lvg) isolated from gut cecum samples of healthy poultry birds (hen).

Organization of seminiferous epithelium in primates: relationship to spermatogenic efficiency, phylogeny, and mating system.

The succession in time and space of specific germ cell associations, denoted as spermatogenic stages, is a typical feature of mammalian spermatogenesis. The arrangement of these stages is either single stage (one spermatogenic stage per tubular cross-section) or multistage (more than one spermatogenic stage per tubular cross-section). It has been proposed that the single-stage versus multistage arrangement is related to spermatogenic efficiency and that the multistage arrangement is typical for hominids.
