On the 15th hypokinetic day carcass mass, glycogen and lipid content in skeletal muscles decreased while collagen content increased. The content of collagen returned to the norm by the 7th day of the recovery period. By that time the glycogen content increased significantly and a week later decreased noticeably. The content of total lipids and triglycerides was higher than the baseline level on the 15th and 30th days of the recovery period. On hypokinesia day 30 carcass mass and glycogen content decreased while collagen content increased. After 30-day hypokinesia glycogen was significantly increased on the 7th day and returned to the norm by the 60th day of the recovery period. Lipid content was elevated only on the 7th day of the recovery period, collagen content returned to the norm on the 15th day of the recovery period. Following 15- and 30-day hypokinesia carcass mass returned to the baseline level by the 30th day of the recovery period.

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Cell Atlas Along the Gut-Brain Axis

Profiling cells along the gut-brain axis at the single cell level will provide unique information for each cell type, a three-dimensional map of how cell types work together to form tissues, and insights into how changes in the map underlie health and disease of the GI system and its crosstalk with the brain.
