Abstract

Mechanisms involved in the development of the alcoholic fatty liver in KK-Ay mice were investigated. Incorporation studies using [14C]acetate and [3H]palmitate indicated that the half-life of hepatic triglycerides was doubled in the ethanol-ingesting mice, and utilization of the exogenous fat was significantly increases as compared with that of the control. No persistent alteration was recognized in hepatic oxidation of palmitate, as estimated by in vitro experiments using liver slices obtained from control and ethanol-drinking mice. Enzymic studies indicated that the activities of acetyl COA carboxylase, ATP citrate lyase, malic enzyme, and 6-phosphogluconate dehydrogenase were increased with ethanol drinking. The increment in hepatic triglycerides accumulated during ethanol ingestion was largely accounted for by palmitoleic, oleic, and linoleic acids. These findings demonstrated an augmentation in hepatic lipogenesis as well as an increased utilization of exogenous fats. Ethanol drinking did not cause any appreciable change in plasma triglyceride level and metabolism of adipose tissue. In summary of the present studies, accelerated lipogenesis and increased utilization of the dietary fats may be possible causal factors in the...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.

Alzheimer's Disease: MS4A

Variants within the membrane-spanning 4-domains subfamily A (MS4A) gene cluster have recently been implicated in Alzheimer's disease in genome-wide association studies. Here is the latest research on Alzheimer's disease and MS4A.

Pediculosis pubis

Pediculosis pubis is a disease caused by a parasitic insect known as Pthirus pubis, which infests human pubic hair, as well as other areas with hair including eye lashes. Here is the latest research.
