background: estradiol and progesterone as well as hippocampal gabaa receptors are believed to play a role in the modulation of pain. the aim of present study was to investigate the effect of intrahippocampal injections of gabaa receptor agonist (muscimol) and gabaa receptor antagonist (picrotoxin) on pain sensitivity during estrous cycle. methods: pain sensitivity was evaluated in rats by forma...

the transcriptional factor sox2 regulates the expression of some of the developmental genes, which are essential for the maintenance of pluripotency of stem cells. sox2 also expresses in the female gamete during folliculogenesis, but its role remains ambiguous. the aim of this study was to investigate the expression of sox2 in the mice ovarian tissue during different stage of estrous cycle. adu...

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 ...

Introduction: Estrogen and progesterone are supposed to modify pain sensitivity. However, the actual role of each of these steroid hormones in this respect is not well known. Plasma concentrations of these hormones show variation during estrous cycle. The role of alpha2 receptors in tonic pain has been pointed out. The aim of the present study was to investigate the agonist and antagonist effec...

The new theories on international economic indicate that the shocks from trade and financial integrations have different effects on business cycle synchronization. This paper investigates these effects on business cycle synchronization in ECO Countries, during 1993-2011 by introducing a new and dynamic cross correlation index. The results show that an increase of trade and financial transaction...

In this work, a new control scheme for synchronization of AC microgrids with upstream power grid is presented. The effects of V2Gs (vehicle to grid) dynamics on synchronization process is studied. This new control approach is based on the optimal fractional calculus and has been developed for synchronization of the microgrid. The V2Gs effect on the dynamics of the microgrid is analyzed through ...

Cows induced to ovulate small dominant follicles were reported to have reduced pregnancy rates compared with cows that ovulated large follicles. The reason for the presence of small dominant follicles at the time of GnRH-induced ovulation in timed AI protocols is unknown. The objectives of this experiment were to examine the role of day of the estrous cycle at initiation of treatment on ovulati...

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...
