to investigate uterine fluid and serum copper (cu) and zinc (zn) variations during the estrous cycle in water buffaloes, 71 genital tracts and blood samples were collected from the abattoir in urmia, iran. the phase of the estrous cycle was determined by examining ovarian structures; 18, 15, 16 and 22 were pro-estrous, estrous, met-estrous and diestrous, respectively. the uterine fluid was coll...

Nowadays, atomic-force microscopy plays a significant role in nanoscience and nanotechnology, and is widely used for direct measurement at atomic scale and scanning the sample surfaces. In tapping mode, the microcantilever of atomic-force microscope is excited at resonance frequency. Therefore, it is important to study its resonance. Moreover, atomic-force microscopes can be operated in fluid e...

background: despite a high prevalence of endometriosis, there still exist many challenges in diagnosing the disease. this study aims to evaluate non-invasive and practical diagnostic methods by measuring serum and peritoneal fluid ca 125 levels in patients with endometriosis. a secondary aim is to determine the correlation between these markers with the stage of disease as well as the relations...

background: determination of oocyte fertilization and embryo quality are one of the most important purposes in art cycles. follicular fluid provides an important microenvironment for development of oocytes and some biochemical characteristics of the follicular fluid, such as pregnancy-associated plasma protein-a (papp-a), may play an important role in prediction of success rate of art. objectiv...

Background: Adiponectin is an adipocytokines which is secreted from the adipose tissue of human and domestic animals. No information is available regarding the follicular fluid adiponectin concentrations in dairy cows. Therefore, the aim of the present study was to determine the follicular fluid adiponectin concentrations in different-sized follicles in the luteal phase of the estrous cycle in ...
