Oxidative metabolism of funicular tissue. II. Determination of the activity of certain Krebs cycle enzymes

Previous experiments have suggested that a partial metabolic block might restrain the oxidative metabolism of the cord tissue between the decarboxylation of pyruvate and the oxidation of succinate. Some of the dehydrogenases of the Kreb's cycle were assayed on acetone powders prepared from human cords. Isocitrate dehydrogenases (both NAD and NADP-specific) have much lower activities than the alpha-ketoglutarate- and malate dehydrogenases; a partial block might be located at this level. Moreover, the malic enzyme has a rather high activity, and might play a significant role by regenerating NADPH in a tissue where other sources of this coenzyme are practically absent.

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.
