background & aim: parkinson's disease (pd) can be created with loss of dopaminergic substantial nigra neurons which is widely associated with oxidative stress and reduced glutathione (gsh), as the most important and abundant thiol in tissues and one of the antioxidant defense, is one of the earliest biochemical events related to parkinson's and consumption of antioxidants has a protective e...

background: tannase can be obtained from the various sources for example tannin rich plants; however microbial sources are preferred for industrial production. in microbial sources, the aspergillus and penicillium genus and lactic acid bacteria mostly produce tannase. however, it has been identified that this enzyme is produced by many fungi and bacteria, but researches are continuing to find n...

conclusions in this study¸ rosa damascena and mefenamic acid had similar effects on pain intensity of primary dysmenorrhea . with further studies, rosa damascena which has no chemical side effects¸ can be suggested for treating primary dysmenorrhea. results there was a significant difference between the average of pain intensity at different hours of measurement in each group after the end of f...

this investigation determined that vitamin c intake of c.w. was higher than o.p. , s. c. and c. statistically, there was a significant difference between c.w. and c. blood ascorbic acid levels of o.p. and s.c. were lower than c.w. and c. , a significant difference was observed. urinary vitamin c in all groups was lower than controls and this indicates that even though vitamin c intake was high,...

background : vitiligo is an acquired disease of skin that presents with depigmented patches due to lack of melanocytes in the epidermis. accumulation of toxic free radicals like hydrogen peroxide in the epidermis may be responsible for melanocytes death. since ethyl vanillate (vanillic acid ethyl ester) is a strong hydrogen peroxide scavenger, it may be effective against vitiligo. this study wa...

in this work, the effects of acetic and lactic acids addition to rice during cooking, on the texture and morphological properties, and too, the gelatinization temperature (gt) of the cooked domsiyah rice was investigated. all experiments were carried out in triplicate and data analyzed in randomized completely by spss15 software. the results showed that acid addition to rice during cooking caus...

an efficient and simple procedure for the synthesis of 1,8-dioxo-octahydroxanthenes from the aromatic aldehydes and 5,5-dimethylcyclohexane-1,3-dione (dimedone) in the presence of boric acid [bo3h3 or b(oh)3] as an inexpensive and reusable catalyst is described. the salient features of this methodology are: the elimination of corrosive liquid acids, high yields, simple methodology, short reacti...
