Extensive Allelic Diversity of MHC Class I in Wild Mallard Ducks.

MHC class I is critically involved in defense against viruses, and diversity from polygeny and polymorphism contributes to the breadth of the immune response and health of the population. In this article, we examine MHC class I diversity in wild mallard ducks, the natural host and reservoir of influenza A viruses. We previously showed domestic ducks predominantly use UAA, one of five MHC class I genes, but whether biased expression is also true for wild mallards is unknown.

Crude Ethanol Extract of Pithecellobium ellipticum as a Potential Lipid-Lowering Treatment for Hypercholesterolaemia.

If left untreated, hypercholesterolaemia can lead to atherosclerosis, given time. Plants from the Fabaceae family have shown the ability to significantly suppress atherosclerosis progression. We selected four extracts from Pithecellobium ellipticum, from the Fabaceae family, to be screened in a 3-hydroxy-3-methylglutaryl coenzyme A reductase (HMG-CoA reductase) assay.
