in the present study, the production of dextran from date extract and sucrose as carbon sources by the bacterium leuconostoc mesenteroides nrrl b512 (f) was investigated. in comparison to blue dextran (mw≈2000 da), dextran molecular weight was reduced (mw2000 kda). flow behavior indices of dextran solutions from date extracts were investigated and rheological parameters were evaluated at concen...

the objective of present study was to investigate the effects of aqueous garlic extracts, vitamin e and n-acetylcysteine on lead-induced lipid peroxidation, changes in antioxidant defense system and semen quality in the rat testes. twenty-five male rats were divided into five groups. animals within different treatment groups were maintained on their respective diets for 35 days as follows: grou...

starch is found in abundance in nature and it is one of the raw materials used for food packaging because of the low price, biodegradability, good mechanical and barrier properties. the recycling ability of coating materials was significantly increased by using edible films and coating in comparison to traditional packaging and it could be an alternative for synthetic films. in this research, t...

barrier properties are one of the most important factors in the edible film. in this study, edible mungbean films were prepared containing (0%, 15%, 30%, 45%) concentrations of rosemary aqueous extract. then the effect of rosemary was investigated on colorimetric and barrier properties (water vapor permeability, oxygen permeability). rosemary extract increased the absorption of color in the vis...

objectives: saffron is the stigma of crocus sativus l., which has the potentials to play a role in the treatment of many diseases. although many researches are now going on this precious spice, there are few data on saffron safety in human, especially in patients with chronic mental illnesses. this study aimed to evaluate the short-term safety and tolerability of both saffron and crocin (its ma...

introduction: excessive physical exercise overproduces reactive oxygen species. even if elite sportsmen increase their antioxidant status by regular physical training, this improvement is not sufficient to limit free radical production during the competition period which can be detrimental to the body. this study evaluates the effect of grape seed supplementation along with aerobic exercise on ...

abstractintroduction: diabetes mellitus is the most common human metabolic disease and chronic non healing diabetic foot ulcers are a critical complication for these patients. angipars is a new herbal extract which has been introduced to accelerate healing of these ulcers. the purpose of this study was to investigate the efficacy and safety of oral angipars in patients with chronic diabetic foo...

the aim of this study was to evaluate the effects of tannic acid (ta) and pistachio by-product tannin extract (pbe) on n utilization and efficiency of microbial nitrogen synthesis (emns) in saanen dairy goats. the experimental design was a change over design with three treatments and three periods using six mid lactation multiparous dairy goats. tannic acid solution and pbe were added to fresh ...

background & aim:parkinson's disease (pd) is a kind of disorder in the nervous system, which is characterized with multiple movement disorders. factors such as oxidative stress are the most important causes for the degeneration of dopaminergic neurons in the substantia nigra and occurrence of parkinson's disease. thus, medications that have antioxidant functions could be an interestin...
