When investigating activity of glutamine synthetase of the enzymatic preparations isolated from the brain of rats of 0.5, 1, 3, 12 and 24-month age, no considerable differences were found in the indices of the values Km to a-glutamate and Vmax which are respectively equal to: Km (M-10(-3))=5.5; 3.5; 3.6; 3.9; 5.5; Vmax=3.1; 4.5; 5.0; 5.2 muM were found. When adding various concentrations of a-ketoglutaric acid into the incubation medium the differences are registered in the degree and character of the age changes in brain glutamine synthetase activity in comparison with this enzyme form the liver.

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.

Synthetic Genetic Array Analysis

Synthetic genetic arrays allow the systematic examination of genetic interactions. Here is the latest research focusing on synthetic genetic arrays and their analyses.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

Head And Neck Squamous Cell Carcinoma

Squamous cell carcinomas account for >90% of all tumors in the head and neck region. Head and neck squamous cell carcinoma incidence has increased dramatically recently with little improvement in patient outcomes. Here is the latest research on this aggressive malignancy.
