The effect of oral ingestion of different fractions of onion (Allium cepa)--extract, residue, and whole--at a dose level equivalent to intake of 50 g of onion per day for a 70-kg man, for 30 days, to male adult, normal, albino rats was studied on blood and erythrocyte membrane lipids and certain membrane-bound enzymes. Onion extract and residue showed hypercholesterolemic effect, while whole on...

The free-living soil nematode Caenorhabditis elegans adapts its development to the availability of food. When food is scarce and population density is high, worms enter a developmentally arrested non-feeding diapause stage specialized for long-term survival called the dauer larva. When food becomes available, they exit from the dauer stage, resume growth and reproduction. It has been postulated...

addition to their activity in vitro. Food ingredients usually have to undergo the processes of cooking, ingestion, absorption and metabolism before being transported to each organ and tissue in the body. They are exposed to seasonings and/or heat during cooking, and then to acidic gastric juice, alkaline intestinal juice, etc, in the digestive organs, They consequently have to be stable under t...
