Effects of co-existed proteins on measurement of pesticide residues in blood by gas chromatography–mass spectrometry

urate measurement of pesticides in biological fluids such as blood is important for quantifying environmental exposures. Beyond sample enrichment and separation, the method presented here is focused on studies of interactions between pesticides and co-existed proteins.

The chloroform fraction of guava (Psidium cattleianum sabine) leaf extract inhibits human gastric cancer cell proliferation via induction of apoptosis

The antiproliferative activities of the chloroform fraction (CF) of guava (Psidium cattleianum Sabine) leaf extract were evaluated using several cancer cell lines. Maximum cytotoxicity was observed in SNU-16, a human gastric carcinoma cell line, at concentrations of 50?100?g/ml.
