Abstract

Alcohol is recognized as one etiological factor in pancreatitis and according to recent studies, phospholipase A2 (PLA2) may be an important factor in the pathogenesis of this disease. However, the effect of chronic ethanol ingestion on PLA2 activity has not been studied in pancreatitis. To clarify the possible relation of these two factors 48 male Wistar rats received 15% (v/v) ethanol in drinking water for 12 weeks and 48 rats served as controls drinking tap water. Blood samples were collected from the control animals by puncturing the abdominal aorta. Experimental pancreatitis was induced by intraductal retrograde infusion of normal rat bile and blood samples collected 24 hr after the infusion. PLA2 activities in the plasma were measured by using the substrate with a 3H-labeled fatty acid in position 2. PLA2 activities in the control group were 11.2 +/- 1.3 (mean +/- SE) nmole/ml/min and 21.7 +/- 3.5 twenty-four hours later (P less than 0.05). In alcoholic rats the activities were 11.1 +/- 1.4 and 54.0 +/- 10.3, respectively (P less than 0.003). The increase of the activities was greater in alcoholic rats and the difference between the groups statistically significant (P less than 0.025). The mortality rate was 4.2% among th...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.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

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.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
