Chemical composition and in vitro polysaccharide fermentation of different beans (Phaseolus vulgaris L.).

The composition of bioactives including polysaccharide yield and resistant starch (RS) content of 4 raw and cooked bean (Phaseolus vulgaris L.) cultivars was evaluated. Polysaccharide was fermented in vitro by incubation with human gut flora under anaerobic conditions and short-chain fatty acids (SCFAs) production was compared at 6, 12, and 24 h by gas chromatography.

Thinner inhalation effects on oxidative stress and DNA repair in a rat model of abuse.

Humans can come into contact with thinner by occupational exposure or by intentional inhalation abuse. Numerous studies of workers for genotoxic effects of thinner exposure have yielded conflicting results, perhaps because co-exposure to variable other compounds cannot be avoided in workplace exposure studies. In contrast, there is no data concerning the genotoxic effects of intentional inhalation abuse.

Antioxidant capacity and antimutagenic activity of natural oleoresin from greenhouse grown tomatoes (Lycopersicon esculentum).

Natural oleoresins rich in lycopene were obtained from two varieties of tomato (Zedona and Gironda) and their nutraceutical potential (antioxidant and antimutagenic capacity) was evaluated. Both oleoresins had a high content of lycopene, 58.33+/-1.
