Foraging animals must often decide among resources which vary in quality and quantity. Nectar is a resource that exists along a continuum of quality in terms of sugar concentration and is the primary energy source for bees. Alternative sugar sources exist, including fruit juice, which generally has lower energetic value than nectar. We observed many honeybees (Apis mellifera scutellata) foragin...

The in vivo micronucleus assay was used to examine the anticlastogenic effects of crude extracts of Bridelia ferruginea, Vernonia amygdalina, Tridax procumbens, Ocimum gratissimum, and Lawsonia inermis in Wistar albino rats. Extracts of doses of 100 mg/kg body weight were given to rats in five groups for seven consecutive days followed by a single dose of 2-AAF (0.5 mmol/kg body weight). The ra...

Gynura procumbens (Lour.) Merr (family Compositae) is cultivated in Southeast Asia, especially Indonesia, Malaysia and Thailand, for medicinal purposes. This study evaluated the in vivo hypoglycemic properties of the water extract of G. procumbens following 14 days of treatment and in vitro in RIN-5F cells.
