the effects of pesticide endosulfan (an organochlorine compound), on the ovaries of bluegill fish (lepomis macrochirus) were studied. exposures for 24 hs with histological preparations at 25% (0.25 î¼g/l), 75 % (0.75 î¼g/l), and 100 % (1 î¼g/l) sub lethal concentrations were examined. the control contained an abundance of the different stages of oocytes (oocytes i, ii, iii, and iv) and had an i...

The Key Role of Inflammation and Oxidative Stress in Polycystic Ovary Syndrome Testicular Torsion: A Review Their Induction Rat Model

The aim of this study was to evaluate the effect of ovarian tissue fragmentation before preservation at 4C in MEM on the morphology, apoptosis, and growth of ovine preantral follicles. After collection, the ovaries were divided into two halves, being one divided into two fragments (1/4 of the ovary). One fragment was subdivided into two fragments (1/8), being one fixed for histology (fresh cont...

CCNE1 gene amplification is present in 15-20% ovary tumor specimens. Here, we showed that Cyclin E1 (CCNE1) was overexpressed in 30% of established ovarian cancer cell lines. We also showed that CCNE1 was stained positive in over 40% of primary ovary tumor specimens regardless of their histological types while CCNE1 staining was either negative or low in normal ovary and benign ovary tumor tiss...

objective(s): several researchers have reported the relationship between infertility in male and varicocele for so many years but the implication of varicocele in female patients is remains elusive. here, we aim to examine the effects of unilateral varicose ovarian vein on antioxidant capacity and oocyte quality of rat ovary after the experimental creation of varicocele in female rats. material...
