CRH/urocortin-receptor-binding protein (CRH/UCN-R-BP) mRNAs are dynamically expressed in the primate ovary during the menstrual cycle. Therefore, studies were designed to localize CRH/UCN-R-BP mRNAs to ovarian cell types, quantitate protein expression during the corpus luteum (CL) lifespan, and investigate the role of this system in the macaque ovary at midcycle. Monkey ovaries were removed dur...

BACKGROUND Strong oestrous symptoms in the mare can cause problems with racing, training and handling. Since long-acting progesterone treatment is not permitted in mares at competition (e.g. according to FEI rules), there is a need for methods to suppress unwanted cyclicity. Spontaneous dioestrous ovulations in the late luteal phase may cause a prolongation of the luteal phase in mares. METHO...

in this study the reproductive organs of adult and apparently healthy female azarbaijan buffaloes werecollected after slaughter from abattoir. through observation of the ovaries, the luteal and follicular phases ofeach buffalo were specified. a total number of 36 oviducts at follicular phase and 36 oviducts at luteal phasewere collected and 3 tissue samples were taken from 3 regions of infundib...

The present report shows that nicotine enhances some of alcohol's positive and negative effects in women and that these effects are most pronounced during the luteal phase of the menstrual cycle. Ten low progesterone and 10 high progesterone/luteal-phase women received nicotine patch pretreatments (placebo or 21 mg) 3 hours before an alcohol challenge (0.4 g/kg). Subjective effects were recorde...

s Background:Sexual dimorphism in coronary artery disease (CAD) mortality is attributed to the cardioprotective effects of estrogen.This is reinforced by the observation that incidence of myocardial infarction is higher in menstrual phase, corresponding with low estrogen levels, in people who are predisposed to CAD due to the presence of modifiable risk factors. Cyclical variability of estrogen...

OBJECTIVE Since the clinical picture of premenstrual dysphoric disorder (PMDD) in the Luteal phase of the menstrual cycle is characterized by extreme negative affect, we predicted and obtained a change in frontal cortical EEG alpha asymmetry, which has been shown to be an index of affect. METHOD We observed two monthly cycles for five women diagnosed as having PMDD and one monthly cycle for f...

Air pollution can influence women's reproductive health, specifically menstrual cycle characteristics, oocyte quality, and risk of miscarriage. The aim of the study was to assess whether air pollution can affect the length of the overall menstrual cycle and the length of its phases (follicular and luteal). Municipal ecological monitoring data was used to assess the air pollution exposure during...

Because the establishment of pregnancy begins at the uterine horn ipsilateral to the corpus luteum (ipsi-horn) in cattle, levels of progesterone (P4) and receptor expression in the endometrial tissue, which regulate the intrauterine environment for embryo development, may differ between the ipsi-horn and the uterine horn contralateral to corpus luteum (contra-horn). The aim of the present study...

STUDY QUESTION Do differences in endometrial gene expression exist after ovarian stimulation with four different regimens of triggering final oocyte maturation and luteal phase support in the same patient? SUMMARY ANSWER Significant differences in the expression of genes involved in receptivity and early implantation were seen between the four protocols. WHAT IS KNOWN ALREADY GnRH agonist t...
