Cancer has a complex etiology with multiple risk factors that involve the interplay between genetic and environmental influences. There is compelling evidence that dietary plant foods appear to be protective against certain type of cancers. Among a number of mechanistic hypotheses, diet-derived antioxidants have been proposed to contribute to explain these findings. However, contrasting results...

The purpose of the present study was to test the possible plant thermotolerance role of isoprene and to study its relationship with non-enzymatic antioxidants and terpene emissions. The gas exchange, chlorophyll fluorescence, extent of photoand oxidative stress, leaf damage, mechanisms of photoand antioxidant protection, and terpene emission were measured in leaves of Quercus ilex seedlings exp...

BACKGROUND Oxidative stress, resulting from an antioxidant/prooxidant imbalance, seems to be crucial in atherogenesis. Recent evidence has emerged, however, of a surprisingly high content of low-molecular-weight antioxidants in human atherosclerotic plaques, although other antioxidant systems have not been investigated in these lesions. METHODS AND RESULTS We studied glutathione-related antio...

Amorphophallus commutatus ( Araceae) a rare cormous herb endemic to western ghats has been used by the tribes of sitamata wild life sanctuary, Rajasthan, India and tribes living in the Western Ghats, India for various ailments. The current study was carried out with an objective to investigate the enzymatic and non enzymatic contents of the tuber and leaves of the plant adopting eight enzymatic...

Oxidative stress appears very early in the history of type 2 diabetes complications. It is associated to glucose oxidation but also lipid peroxidation. This can be accentuated by a decrease antioxidant capacities diabetics, especially if there are other comorbidities. The objective this study was evaluate capacity Senegalese diabetics and identify risk factors.
 We conducted prospective 40...

Plants respond to various stresses during their lifecycle among which abiotic stress is the most severe one comprising heat, cold, drought, salinity, flooding, etc. take a heavy toll on crop yield worldwide in every corresponding year. ROS has dual role mechanisms where, at high levels, they are toxic cells while same time, molecule can function as signal transducer that activates local well sy...

BACKGROUND Pterygium is a disorder of the ocular surface induced by chronic exposure to UV-light. Abundant data is available from patients with primary pterygium, but scarce from those with recurrent pterygium. The present study aimed to explore the oxidant/antioxidant status in tissue of primary and recurrent pterigium in men and women. METHODS Pathological tissue samples were taken during s...

PURPOSE To determine enzymatic antioxidant and lipid peroxidation levels in seminal plasma of patients orchiectomized for testicular tumors. MATERIALS AND METHODS The study included 52 patients: 26 control men and 26 orchiectomized patients for testicular tumor, of which 12 men had seminoma tumor and 14 men non-seminoma tumor. After semen analysis performed according to the WHO guidelines, an...
