Abstract

This review discusses changes in protein, carbohydrate and lipid metabolism of animals during their readaptation after exposure to hypokinesia of varying duration. It is concluded that at an early stage of readaptation anabolic reactions aimed at the recovery of the bulk of active muscle proteins and the amount of energy substrates are predominant. In this situation the synthesis of lipids and carbohydrates is prevailing over their utilization. It is postulated that during readaptation amino acids are used more actively to make up for energy expenditures, gluconeogenesis and lipid synthesis. In the course of readaptation wave-like metabolic changes occur, being sometimes greater than during hypokinesia.

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.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.
