this study was designed to evaluate the detrimental effect of atrazine (atr) on germinal epitheliums (ge) cytoplasmic carbohydrate (ch) and unsaturated fatty acids (ufa) ratio and to clarify the effect of atr on serum levels of fsh, lh, testosterone and inhibin-b (inh-b). the impact of atr exposure on total antioxidant capacity (tac), sperm dna packing and integrity were also investigated. seve...

background: the exact pathophysiology of testicular degeneration, following varicocele has not been completely understood yet.   objective: the current study was designed to determine the effect of varicocele on germinal epithelium (ge) cytoplasmic biohistochmical alterations.   materials and methods: to follow-up this study, left varicocele was induced in test groups. non-varicocelized rats we...

background: nowadays it is proofed that the uterine artery plays essential role in follicular growth and/or post parturition hemorrhagic. objective: this study was conducted to evaluate the effect of bilateral uterine artery ligation (bual) on follicular fate and the probable histochemical changes of the carbohydrate and lipids in the ovaries of rabbits. materials and methods: 24 mature female ...

a random block experiment 4×4 with sixteen diets containing four level of protein (35, 40, 45 and 50%) at four carbohydrate to lipid level (1.7, 1.4, .1 and 0.8 ) were designed to research about the ability of utilization of different levels of protein and carbohydrate to lipid ratios diet for juvenile huso huso ( 5.4 ± 0.2, mean sd )in fourteen weeks. fish fed 2-3% of body weight at each day. ...

fasting induces short-term physiological adaptations which spare the body's remaining carbohydrate stores and mobilize lipid stores to provide a substitute fuel for many tissues and organs, especially skeletal muscle. rodent studies show that regular occurrence of fasting then refeeding, stimulates adaptations in muscle which make the animal better placed to withstand a further period of fastin...

data regarding the effects of dietary protein on modifying serum lipid and lipoprotein levels are controversial. in this study we have investigated the hypothesis whether dietary protein and protein to carbohydrate ratio could be related to subsequent changes in lipid profile in adults.this 3-yaers follow-up_longitudinal study was conducted on a sample of participants (845 men and 1043 women, a...

BACKGROUND This research studied the effect of ciprofloxacin (CPFX) on spermatogenesis. We aimed to estimate the effect of CPFX on serum levels of testosterone, LH and FSH. MATERIALS AND METHODS In this experimental study, a total of 24 mice were assigned to controlsham and test groups. We subdivided the test group into low (206 mg/kg) and high (412 mg/kg) dose CPFX groups. Control-sham anima...

introduction: intracellular ph (phi) regulates essentially all aspects of cellular activities. however, it is unknown how endoplasmic reticulum (er) potassium channels sense phi. in this study, we investigate the direct effects of phi on er potassium channels. methods: we used channel incorporation into the bilayer lipid membrane method. l-α-phosphatidylcholine, a membrane lipid, was extracted ...

in this study, the energy reserves of prediapause and diapausing adult bugs were examined using colorimetric biochemical techniques to determine carbohydrates, lipids, glycogen, and protein content. to this end, 45-day-old bugs were obtained from three different sources: laboratory colony, cold-stored insects, or natural habitat. the results showed that prediapause males and females had signifi...
