in order to maintain the quality and increase the shelf life of fruits, many studies have been carried out in terms of the packaging specially applications of the nano-composite packages in the packaging. because of the low storage ability of the plum fruit, in this study, the effects of the four nano-composite packages and common polyethylene (as a control) were analyzed on maintaining quality...

Smoking during pregnancy leads to decreased pulmonary function and increased respiratory illness in offspring. Our laboratory has previously demonstrated that many effects of smoking during pregnancy are mediated by nicotine. We now report that vitamin C supplementation can prevent some of the effects of maternal nicotine exposure on pulmonary function of offspring. Timed-pregnant rhesus monkey...

Vitamin C content and sensorial properties have been evaluated in air-dried carrots previously subjected to different ultrasound (US) or conventional blanching pretreatments. In addition, mass spectral fingerprints obtained by the Headspace ChemSensor System have been evaluated for the first time for classification of carrots according to their processing. Conventional blanching treatments at h...

Vitamin B-12 (also called cobalamin) is essential for human health and current intake levels of vitamin B-12 are considered to be too low. Natural enrichment of the vitamin B-12 content in milk, an important dietary source of vitamin B-12, may help to increase vitamin B-12 intake. Natural enrichment of the milk vitamin B-12 content could be achieved through genetic selection, provided there is ...

abstract          background and objective: vitamins c and e are  the two main antioxidants involved in prevention of type 2 diabetes, by reducing oxidative stress. the aim of this study was to evaluate the effects of vitamins c and e supplementation independently, on serum levels of insulin, high sensitivity c-reactive protein (hs-crp) and resistin in people with type 2 diabetes.         metho...

The in vivo effect of vitamin D on (Ca2+ + Mg2+)ATPase activity was examined in a plasma membrane fraction of rat circulating mononuclear cells (MPM). Although there was no significant difference in the ATPase activities in red blood cell ghosts, (Ca”’ + Mg2+)-ATPase activity in MPM was significantly higher (p < 0.05) in long-term vitamin DB-replete rats (100 IU/day for 6 months) than that in v...

although some vitamins have been shown to prevent glucocorticoids induced osteoporosis in short time, the magnitude of this effect remains to be clarified. the aim of this study was to evaluate protective effect of vitamin d3 on methylprednisolone acetate (mpa) induced osteoporosis in rats. twenty-four male sprague dawley rats were randomly divided into four groups: group a (n = 6), was a base ...

recently great afford have focused on the production of food and beverages which are rich in phenolic and antioxidant components. the epidemiology investigations have proved that the regular composition of food and beverages are richer in phenolic and antioxidant components can strongly decrease the cardiovascular disease. this was done after the preparation of components such as soymilk mixed ...
