Transvaginal colour and pulsed Doppler ultrasonography analyses of blood flow velocity have indicated that intra-tumoral peak systolic velocity (PSV) is a good indicator of ovarian malignancy. Therefore, we examined whether there was an association between the expression of angiogenic genes, e.g. thymidine phosphorylase (TP) and TIE2 and the PSV of blood flow in normal and cancerous ovaries. In...

The dromedary is one of the few domestic animal species that multiply at a very slow rate. Several factors among others; long gestation, simple and induced ovulation, contribute to reduction reproductive efficiency camel. To help understand camel reproduction in Niger, this study aims morphologically characterize system females slaughtered slaughterhouse. For this, total 132 genital tracts 264 ...

Abstract Reproductive performance of heifers is a key indicator herd productivity. The objective was to evaluate markers and genes associated with reproductive tract characteristics through comparative approach. For this study, 295 admixed beef were examined via transrectal ultrasonography at approximately 13 months age. Exploratory factor analysis antral follicular count (count per size, side,...

BACKGROUND We showed there are specific ALDH1 autoantibodies in ovarian autoimmune disease and ovarian cancer, suggesting a role for ALDH1 in ovarian pathology. However, there is little information on the ovarian expression of ALDH1. Therefore, we compared ALDH1 expression in normal ovary and benign and malignant ovarian tumors to determine if ALDH1 expression is altered in ovarian cancer. Sinc...

objective: polycystic ovary syndrome (pcos) is one of the most common endocrine disorders that is associated with different metabolic, reproductive and psychological consequences. the main aim of this study was to compare the sexual function and quality of life in women with polycystic ovary syndrome and healthy women. materials and methods: this is a causal-comparative study in which 129 women...

There is evidence that one gonad has functional predominance. The present study analyzed the acute effects of unilateral ovariectomy (ULO) and blocking the cholinergic system, by injecting atropine sulfate (ATR), on estradiol (E2) serum concentrations during the estrous cycle. The results indicate that ULO effects on E2 concentrations are asymmetric, vary during the estrous cycle, and partially...

abstract background: “polycystic ovary syndrome (pcos) is a complex endocrine and metabolic disorder associated with ovulatory dysfunction”. “autonomic and central nervous systems play important roles in the regulation of ovarian physiology”. the noradrenergic nucleus locus coeruleus (lc) plays a central role in the regulation of the sympathetic nervous system and synaptically connected to the ...

Purpose To identify which methods used in the assessment of the ovarian reserve are exclusive or complementary to identify the best response to follicle development. Methods Retrospective cohort study, involving patients undergoing assisted reproduction treatment at the Instituto de Medicina Reprodutiva e Fetal, from April 2009 to July 2014. Age, biochemical tests, and ultrasound were assessed....

Calcitonin (CALCA), a hormone primarily known for its role in calcium homeostasis, has recently been linked to reproduction, specifically as a marker for embryo implantation in the uterus. Although CALCA expression has been documented in several tissues, there has been no report of production of CALCA in the ovary of any vertebrate species. We hypothesized that the Calca gene is expressed in th...
