A new variant of hereditary hemolytic anemia due to erythrocyte pyrimidine 5'-nucleotidase deficiency was found in Japan. Biochemical parameters such as the Michaelis constant, thermostability, electrophoresis and pH curve were studied. The variant showed a high Michaelis constant for cytidine 5'-monophosphate, no thermolability, slower electrophoretic mobility and abnormal optimum pH. The results strongly suggest that the mechanism of this enzyme deficiency is due to a structural gene mutation.

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.
