Abstract

The experiments were carried out on 84 white rats. At the beginning of hypokinesia activity of glucose-6-phosphate and 6-phosphogluconate dehydrogenases in the adipose tissue was decreased and in the liver, skeletal muscles and heart increased. On the 30th hypokinetic day the enzyme activity was nearly normal. The dehydrogenase activity increased by the 60th hypokinetic day in the adipose tissue and by the 90th day in the liver and heart, whereas in skeletal muscles it decreased at that experimental stage. After completion of hypokinesia the enzyme activity increased. Possible relationship between these changes in the enzyme activity and disorders of lipid metabolism during hypokinesia is discussed.

COVID-19

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.
