Kinetics of 5--nucleotidase in sera of liver cirrhotic and normal Iraqi individuals

Biochemistry and Experimental Biology
S A Al-Mudhaffar, V Saadalla


5'-Nucleotidase activity was elevated in patients with liver cirrhosis; greater values of 5'-Nucleotidase activity were found in biliary cirrhosis, 5'-Nucleotidase from liver cirrhotic sera was less stable than from normal sera. The velocity of 5'Nucleotidase from liver cirrhotic sera per minute, at t = 10, was greater than normal controls. The optimum (S) for 5'-Nucleotidase was found to be 1.0 mM A-5'-MP, for both normal and liver cirrhotic sera. Km (A-5'-MP) and (2'-d-A-5'-MP) of 5'-Nucleotidase was found to be significantly lower in patients with liver cirrhosis than normal controls.

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.
