purpose the purpose of this study was to examine the differences in physical fitness, physical activity, and sedentary activities among 7 to 11 year old boys with varying body mass index in ardabil, iran. methods the sample consisted of 766 boys who participated in eight weight bearing (1 mile walk/run, sit ups, standing long jump, vertical jump, shuttle run 4 × 10 m, 30-meter sprint, pull ups,...

the aqueous extract of syzygium cumini (pulp) was investigated for its possible hypoglycemic and antioxidant potentials in streptozotocin (stz) induced diabetic wistar female rats. a single intraperitoneal injection of stz at a dose of 55 mg/kg body weight elevated the glucose levels more than 230 mg/dl after 3 days. treatment with the aqueous extract of syzygium cumini (pulp) at 100 mg/kg and ...

Background and Objective: Spermatogenesis and oogenesis stress is a primary epigenetic element that can cause lifelong modifications in neural system functions. This study was designed to elucidate whether preconceptional stress during spermatogenesis and oogenesis affects the seizure behaviors and body weight of the offspring later in life. Materials and Methods: In this experimental study, 1...

Background: Varicocele is a major cause of male infertility, as it may impair spermatogenesis through several distinct pathophysiological mechanisms including hypoxia, renal-adrenal reflux, hormonal dysfunction, autoimmunity, oxidative stress and hyperthermia. HSP70s are members of the heat shock protein (HSP) family, which are considered intracellular chaperones. Their expressions can increase...

We investigated whether stress interferes with fertility during adulthood. Male Wistar rats (weighing 220 g in the beginning of the experiment) were forced to swim for 3 min in water at 32 degrees C daily for 15 days. Stress was assessed by the hot-plate test after the last stressing session. To assess fertility, control and stressed males (N = 15 per group) were mated with sexually mature norm...

conclusions rats fed with a 30% calorie-restricted diet in comparison with to ad libitum fed controls for 8 days had significantly more prominent regression of inflammation. results decline of both body weight and paw volume was significantly more prominent in the case than in the control rats within the study period (p < 0.001 and < 0.001, respectively). paw volume decrease was more prominent ...

Background & Objective: Securigera securidaca is a medicinal plant used in Persian folk medicine to decrease blood sugar. Nevertheless, there is some controversy about its effects. The current study investigated the hypoglycemic activity of the aqueous seed extract of S. securidaca. Materials & Methods: Sixty mature male Charles-River rats were categorized and divided randomly into 10 groups w...

Rosmarinus officinalis has been used in traditional medicine extensively. This study evaluated the hormonal and cellular effects of Rosmarinus officinalis extract on testes of adult rats. Thirty male Wistar rats (in three groups) received 50 or 100 mg/Kg b.w of Rosmarinus officinalis extract (made from the plant’s leaves, flower and stem) (treatment groups) and 10 mL/Kg b.w normal saline (contr...
