A simple, highly sensitive and reproducible method for the assay of gamma-glutamyl transpeptidase (EC 2.3.2-) activity is introduced, using gamma-glutamyl-p-nitroanilide as a substrate and glycylglycine as an acceptor in 50 g/l of polyoxyethylene nonylphenol. Serum transpeptidase activity was assayed in 1080 healthy adults, the normal mean value being 14.8 mU/ml. The diagnostic evaluation of the enzyme in various hepatobiliary diseases is also discussed.

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.
