One of the most important research topics in plastic surgery is the extension of the length of skin flaps that survive. We have investigated the increase in the length of skin flaps that can be achieved by giving dibutyryl cyclic AMP (DB-cAMP) to rabbits with experimental skin flaps and compared the results with those in animals not given DB-cAMP. Three variables, the arrival of DB-cAMP in the critical area of circulation of the flap (n = 6), changes in the blood flow in the flap (n = 10), and increase in the length of skin flap that survived (n = 30) were investigated by high performance liquid chromatography and laser Doppler flowmetry. DB-cAMP reached the critical area of circulation in the skin flap (dye distance), increased the blood flow within this area (mean (SEM) peak value 30 minutes after operation 1.24 (0.06) ml/min/kg compared with 1.06 (0.02) in control flaps), and extended the length of the flap that survived (mean (SEM) length seven days after operation 66.1 (3.0) mm compared with 60.8 (1.8) mm in the control group). We conclude that DB-cAMP improved the blood flow in skin flaps in rabbits with a consequent increase in the length of skin flap that survived.

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.
