mancozeb, a fungicide of a manganese-zinc ethylenebisdithio-carbamate (ebdc), was administered by gavage at doses of 200, 400, 600 and 800 mg/kg/day to female virgin mice for 30 days. the mice were autopsied on 31st day. mice were also treated with similar doses for a period of 30 days and the treatment was withdrawn for a further period of 30 days for reversible study. the mice were autopsied ...

To investigate uterine fluid and serum calcium (Ca) and Magnesium (Mg) variations during the estrus cycle in water buffaloes, 71 genital tracts and blood samples were collected from the abattoir in Urmia. The phase of the estrous cycle was determined by examining ovarian structures. 18 animals were pro-estrous, 15 estrous, 16 met-estrous and 22 diestrous. The uterine fluid was collected by gent...

The Martina Franca (MF) donkey breed, with 48 jackasses and 515 jennies, is considered an endangered breed according to the data from the Monitoring Institute for Rare Breeds and Seeds in Europe. The knowledge of the estrous cycle characteristics has a great impact for assisted reproduction, especially in endangered species. In this study, the estrous cycle characteristics were investigated in ...

We evaluated the changes in estrous cycle of female rats fed either high carbohydrate or high protein diets for 42 days relatively to commercially available rodent pellets. Animals fed high carbohydrate diet showed a lengthened estrus cycle while those fed with a high protein diet could not continue a healthy estrous cycle. Animals received a protein rich diet showed a lengthened estrus cycle w...

The transcriptional factor OCT4 regulates pluripotency of stem cells and has an important role during oocyte growth. Whereas, its role has remained ambiguous in ovarian tissue during reproductive cycle. Therefore, this study was aimed to investigate the expression patterns of OCT4 in mouse ovaries during the normal estrous cycle. Adult National Medical Research Institute mice were classified as...

This study was designed to investigate the relationship between the estrous cycle phases with uterine bacterial and fungal flora in non-pregnant female rabbits. Thirty laboratory mature multiparous rabbits were used for this purpose. Samples from uterine lavage for culture of bacteria and fungi were collected at different stages of estrous cycle (based on vaginal cytology), and histopathologica...

This study aimed to investigate the miRNA expression patterns in granulosa cells of subordinate (SF) and dominant follicle (DF) during the early luteal phase of the bovine estrous cycle. For this, miRNA enriched total RNA isolated from granulosa cells of SF and DF obtained from heifers slaughtered at day 3 and day 7 of the estrous cycle was used for miRNAs deep sequencing. The results revealed ...

Background: The concepts of reproductive biology were changed by stating the ovarian reserve in postnatal mammalian females is replenished. The aim of this study was to investigate the expression of OCT4 in the mice ovarian tissue during different stages of mouse estrous cycle. Materials and Methods: The mice were considered as pro-estrous, estrous, met-estrous and di-estrous based on the cell ...

Previous studies have demonstrated that a number of behaviors change their probability of occurrence during the estrous cycle. Wheel running is known to show estrous-related changes while reports upon intracranial reinforcement (self-stimulation, ICS) have been equivocal. The present studies examined both behaviors to further resolve the underlying behavioral determinants of these estrous effec...

It was assumed that uterine stem cells are responsible for the unique regenerative capacity of uterine. Therefore, the aim of the present study was to investigate the expression of the pluripotent stem cell markers in the mice uterine tissue during different stages of estrous cycles. Twelve virgin female NMRI mice (6 to 8 weeks old) were considered at proestrus, estrus, metestrus and diestrus a...
