background and objectives: periodontal disease is a chronic disorder with a high prevalence. there are few studies about the role of diet in prevention and treatment of periodontal disease. the aim of this study was to evaluate the effect of consumption of chicory leaf extract in adjunct with non-surgical periodontal therapies on serum antioxidant and lipid status. materials and methods: this s...

objective: the aim of this study was to determine the oxidative stress; serum level of total antioxidant capacity (tac)and malondialdehyde (mda) level and the depression score among the depressed rotational shift workers in shahid tondgouyan refinery in tehran (iran). methods: a cross-sectional study was conducted among all the 189 shift workers in shahid tondgouyan oil refinery who were eligib...

abstract having no exact knowledge of most appropriate harvesting time in kiwifruit grown in different regions of guilan province, as well as the low storage longevity of the fruits are the most important factors causing considerable reduction in both marketability and export affairs. in this study, the influence of fruit quality in term of harvesting time on the postharvest quality and food va...

The accurate assessment of oxidative stress in biological systems is a problem for all investigators working on the role of free radical damage in disease. Numerous assays have been described to measure various free radical damage products or antioxidant status, and the plethora of available techniques attests to the fact that no ideal method is available. The concept of a single test that migh...

this study examined if pre-germination altered the water content and water activity, contents of phytate, total phenolic, (±)-catechin, quercetin and total antioxidant capacity of almond  (prunus dulcis)kernel. raw almond kernels were submerged for 15 hours in water, 0.02 mol dm-3 phosphate buffer solution (ph 5.0) and 0.02 mol dm-3 phosphate buffer solution (ph 7.0) at 25 and 40ºc, respectivel...

background: diabetes mellitus is associated with chronic changes in peripheral arteries because of oxidative stress and insufficient antioxidative defense mechanism. omega-3 fatty acid supplementation could be effective in some diabetes complications; however, polyunsaturated fatty acids may increase lipid peroxidation. this study aimed to determine whether eicosapentaenoic acid alone or in con...

background: there is growing evidence that damage to spermatozoa by reactive oxygen species (ros) play a key role in male infertility. objective: the aim of the present study was to assess the antioxidant status of seminal plasma by measuring total antioxidant capacity (tac) and activities of catalase and superoxide dismutase (sod) in men with asthenozoospermia, asthenoteratozoospermia and olig...

background: fat-rich diet may alter oocyte development and maturation and embryonic development by inducing oxidative stress (os) in follicular environment. objective: to investigate the relationship between fat intake and oxidative stress with oocyte competence and embryo quality. materials and methods: in observational study follicular fluid was collected from 236 women undergoing assisted re...

background: the role of attenuation in antioxidant capacity or expansion of pro-oxidant/oxidant is well known for the development of stress oxidative. the aim of this study was to evaluate the plasma antioxidant capacity along with uric acid in patients with diabetic nephropathy (dn+) and without diabetic nephropathy (dn-). materials and methods: the research population included 88 patients wit...

ethanolic extract of leaves of elaeocarpus ganitrus was analyzed for their total antioxidant capacity, reducing power, metal chelating, abts+ (2, 2-azinobis-(3-ethylbenzothiazoline-6-sulphonate) radical scavenging and hydroxyl radical scavenging activities. the extract at 500 ?g/ml showed maximum iron chelating activity (76.70%) followed by the scavenging of the abts+ radical (55.77%) at the sa...
