objective: exercise activity could be an amendment to polycystic ovary syndrome (pcos). however the acute and chronic effects of various exercise intensities on serum leptin levels are ambiguous. this study investigates the acute and chronic responses of various intensities of exercise on serum leptin levels and weights of female rats with pcos. methods: in this semi-empirical study, 80 adult w...

Purpose Here, we studied the beneficial effects of aerobic exercise on metabolic syndrome components, cognitive performance, brain derived neurotrophic factor (BDNF) and irisin in ovariectomized rats with different serum vitamin D (Vit D) status. Methods Eighty female wistar rats were divided into 2 groups of sham operated (sham, n = 8), and ovariectomized (OVX, n = 72). Then OVX were divided...

[Purpose] This study was conducted on adolescent subjects whose brains are still developing with the purpose of identifying the effect of 8 weeks duration of aerobic exercises on the expression of BDNF, IGF-1 and cortisol, to identify effect of aerobic exercise on the expression of cortisol, BDNF and IGF-1 related to nerve cell growth. [Subjects and Methods] The subjects were 20 junior-high sch...

this experiment was conducted to evaluate the effects of vitamin c on laying hens performance, egg characteristics and some blood parameters under normal rearing condition. one hundred and ninety two 24 - weeks - old laying hens diet were used in a completely randomized design with 4 treatments (0, 250, 500 and 750 mg vitamin c/kg diet) and 4 replicates for 105 days. although feed consumption, ...

background: ascorbic acid (vitamin c) is one of the most commonly water soluble vitamins. extra energy is necessary for the exercise is not often attributed to intake of vitamin c, long-term and intense exercise can lead to oxidative damage to cellular compounds and also contribute to muscle fatigue and decrease exercise performance. limited data are available regarding to the efficacy of vitam...

this study was undertaken to assess vitamin c status in allergic children. twenty-six allergic patients and 46 apparently healthy controls aged 7-16 years of both sexes were introduced. all patients were diagnosed being allergic based on their histories, physical examinations and laboratory findings. blood samples were obtained between 09.00-11.00 to determine total serum immunoglobulin e, hist...

Background & Aims: Immune system abnormalities such as inflammation, increased autoimmunity and the skewed expression of soluble mediators, including cytokines have been observed in autistic patients. The present study aimed to compare the effects of vitamin D supplementation and/or aquatic exercise training on the serum level of inflammatory cytokines, including IL-1β and IL-1RA, and stereotyp...
