The virus known to infect person through spreading small liquid particles or droplets from an infected when they talk, cough, sneeze, breathe. Therefore, it important slow down physical distancing between individuals. main objective this writing identify the current layout enclosed public spaces incorp...

Trains of action potentials in CA1 pyramidal neurons are followed by a prolonged calcium-dependent postburst afterhyperpolarization (AHP) that serves to limit further firing to a sustained depolarizing input. A reduction in the AHP accompanies acquisition of several types of learning and increases in the AHP are correlated with age-related cognitive impairment. The AHP develops primarily as the...

Lentiviruses (LV) are nononcogenic viruses, belonging to the Lentivirinae subfamily. The name comes from the Latin word “lenti”, meaning “slow”. According to the definition of B. Sigurdsson, they are causing infections in a limited number of hosts with a long incubation period (months and years) and progressive course, accompanied by damage in definite organs/tissues and a lethal outcome (Sigur...

Two-pore channels (TPCs) have recently emerged as a novel class of non-selective cation channels in the endolysosomal system. There are two members in the human genome, TPC1 and TPC2. Studies with TPC knockout and knockdown models have revealed that these channels participate in the regulation of multiple endolysosomal trafficking pathways which when dysregulated can lead to or influence the de...

rust diseases continue to cause significant losses to wheat production around the world. among them, yellow rust caused by puccinia striiformis f. sp. tritici is an important disease that threatens wheat production in most cool environments. host resistance, especially race- nonspecific resistance, is the most economical way to manage wheat stripe rust disease. in this study, the effectiveness ...

Background: Scleroderma is a chronic systemic disorder that affects the connective tissues. It is characterized by several immune manifestations, inflammation, vascular damage, and fibrosis. Some of the viral infections with complex mechanisms are involved in the development and progression of many autoimmune diseases, such as scleroderma. The present study aimed to investigate the serological ...
