An experiment was performed in which Wistar male rats were exposed to a N2-O2 atmosphere at 10 kgf/sm2 or He-O2 atmosphere at 10 and 40 kgf/cm2. During the experiment grooming and motor activity as well as plasma corticosterone were investigated. Irrespective of the atmosphere composition, behavioural and biochemical parameters were found to increase significantly. At 10 kgf/cm2, the grooming frequency returned to normal faster than at a higher pressure. These observations give evidence for a nonspecific effect of the above hyperbaric factors on the parameters taken under study.

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.
