Follicular fluid (FF) provides a very important microenvironment for the development of oocyte maturation, ovulation and fertilization. The objective of this study was to determine the effect of different charged groups of cow follicular fluid proteins on in vitro oocyte maturation (IVM) when added to cultured maturation medium. The follicular fluid were obtained from dominant follicle and prec...
The objective of the present study was prospectively and randomly to evaluate the role of L-arginine in improving uterine and follicular Doppler flow and in improving ovarian response to gonadotrophin in poor responder women. A total of 34 patients undergoing assisted reproduction was divided in two groups according to different ovarian stimulation protocols: (i) flare-up gonadotrophin-releasin...
BACKGROUND The possibility that a specific cytokine profile could be detected in the ovaries of patients with polycystic ovarian syndrome (PCOS) was investigated. METHOD Enzyme-linked immunosorbent assay (ELISA) or bioassays were used to assess the concentrations of leukaemia inhibitory factor (LIF), tumour necrosis factor, interleukin 11, gamma interferon, progesterone and oestradiol in foll...
Endothelin-like immunoreactivity specific for endothelin-1 (ET-1), endothelin-2 (ET-2) or big endothelin-1 (big ET-1) was measured, using commercially available radioimmunoassay kits, in follicular fluid collected at the time of oocyte aspiration from 36 women undergoing ovulation induction by human menopausal gonadotrophin (HMG). The relationship of ET concentrations to HMG dose, peak serum oe...
We examined acute exposure of Holstein cows to di(2-ethylhexyl) phthalate (DEHP) and its carryover effects on ovarian function and oocyte developmental competence. Synchronized cows were tube-fed with water or 100 mg/kg DEHP per day for 3 days. Blood, urine and milk samples were collected before, during and after DEHP exposure to examine its clearance pattern. Ovarian follicular dynamics was mo...
ABSTRACT The flavonoid kaempferol has attracted research attention as a potential adjuvant during chemotherapy. This study aimed to evaluate the protective effects of against ovarian damage in cisplatin-treated mice. Two groups mice received saline solution (intraperitoneal injection [i.p.]; control) or single dose cisplatin (5 mg/kg body weight, i.p.). Moreover, two other were pretreated with ...
Rice whitening is an important stage in rice milling process and improvement of the whitener machines has a remarkable effect on rice loss. To decrease the amounts of broken rice and losses, the rotor of the blade whitener was equipped with screw conveyor. To investigate the effects of rotor speed (in four levels: 600, 700, 800 and 900 rpm) and output rate (in three levels: 400, 500 and 600 kg/...
introduction: purpose of this study was the effect of different music rhythms (fast rhythm and slow rhythm) in physiological responses of health young male after an exhaustive exercise session during primary minutes of recovery period. methods: seventeen healthy male (ages: 19.76 ± 0.97 yr, height: 176 ± 6.72 cm, weight: 68.5 ±7 5.95 kg), voluntarily performed bruce protocol until exhaustion wi...
This study was designed to determine the efficiency and rate of testosterone (T) retrograde transfer during the follicular and luteal phase of the estrous cycle in gilts (n=27). The efficiency and the rate of the retrograde transfer of T from the ovarian effluent into blood supplying the ovary were determined for the first time under in vivo conditions. Ovarian arterial blood concentration of T...
