Ribulose-1,5-bisphosphate carboxylase/oxygenase (rubisco) activase, a soluble chloroplast protein which promotes light-dependent rubisco activation, was partially purified from spinach chloroplasts by ion-exchange and gel-filtration fast protein liquid chromatography. The protein could also be isolated using rate zonal centrifugation in sucrose gradients followed by conventional ion-exchange on...

This study investigated the level of pesticide pollution using marrow squash (Cucurbita pepo L.), cherry tomato (Solanum lycopersicum var. cerasiforme), banana pepper (Capsicum annuum), lettuce (Lactuca sativa L.), purslane (Portulaca oleracea L.), green beans (Phaseolus vulgaris L.), cucumber (Cucumis sativus L.), and onion (Allium fl avum L.) in Kirklareli, Turkey. For this purpose, the conce...

BACKGROUND Portulaca oleracea Linn. (Portulacaceae) is commonly known as purslane in English. In traditional system it is used to cure diarrhea, dysentery, leprosy, ulcers, asthma, and piles, reduce small tumors and inflammations. AIM To assess cytotoxic potential of chloroform extract of P. oleracea whole plant against human colon adenocarcinoma (HCT-15) and normal (Vero) cell line. MATERI...

OBJECTIVE To investigate the effects of purslane herb aquenous extracts (PHAS) on the stress ability of aging mice induced by D-galactose. METHODS We observed the survival time to hypoxia and heat survival rate of the mice treated with different doses of PHAS and vitamin E. The contents of lipofuscin and malondialdehyde (MDA), and the activity of superoxide dismutase (SOD) and catalase (CAT) ...

In this study, in vitro and vivo genotoxic effects of Bifenthrin (BIF), an important insecticide used agricultural production, storage processing, were investigated. The genoprotective properties purslane (Portulaca oleracea L.) against the BIF also determined by using methanol (POmet) extract plant. experiments performed with somatic mutation recombination test (SMART) Drosophila melanogaster....
