Abstract

Day-old male, broiler type chicks were used to study the effect of 100 ppm dietary vanadium on fatty acid and cholesterol synthesis and turnover in vivo. After feeding the experimental diets for 4 weeks body weight and liver weight of chicks fed 100 ppm vanadium were significantly less than those of the control chicks and liver total lipid and cholesterol tended to be slightly higher than the levels of the control chicks. [1-14C] Acetate was administered intravenously and the specific activities of plasma and liver total lipid, cholesterol and fatty acid were determined at 0.25, 0.50, 1.0, 4.0, 8.0 and 15.0 hours after the injection. Plasma total lipid and cholesterol were significantly higher than the levels in the control chicks. The rate of incorporation of [1-14C]acetate into plasma and liver total lipid, cholesterol and fatty acid was higher in chicks fed vanadium than the control group at any of the time being tested after the injection. There was a significant increase in the hepatic citrate cleavage enzyme activity among chicks fed 100 ppm vanadium, whereas, there was no significant change in acetate thiokinase activity. Turnover rate of plasma total lipid and fatty acid in vanadium fed chicks was lower than the control...Continue Reading

COVID-19

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.
