Abstract

In experiments on cats it was found using electromagnetic and resistographic methods that sodium hydroxybutyrate (100 mg/kg) considerably increases cerebral circulation. The drug also potentiates the blood flow to the brain during formation of pressor reflexes of the arterial pressure. The blood flow increase is also observed in the system of femoral arteries while in the intestinal artery, on the contrary, there is a reduction in the blood flow increase during vasomotor reflexes. The reflex changes of the resistance in regional vessels are also different: the inhibition of pressor reflexes in the cerebral vessels along with their facilitation in the intestinal and femoral arteries and the potentiation of the reflex dilatatory phase in the limb vessels are seen. Different sensitivity to the drug of synaptic formations in the central links of various regional vasomotor reflexes is likely to underlie the difference described.

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.
