Endoplasmic reticulum stress is involved in mycotoxin zearalenone induced inflammatory response, proliferation, and apoptosis in goat endometrial stromal cells.

Zearalenone (ZEA) is an estrogen-like mycotoxin and is considered a secondary metabolite produced by Fusarium fungi, which are widely found in the surrounding environment. ZEA has been found to cause reproductive dysfunction in female and male animals, but the underlying mechanism remains unclear. Therefore, this study examined cell proliferation, cell apoptosis, autophagy protein expression, and some inflammatory cytokines such as IL-1β and IL-8 of goat endometrial stromal cells (ESCs) induced by different concentrations (0, 15, 30, 60, and 90 µM) of ZEA.

Uterotubal junction of the bovine (Bos taurus) versus the dromedary camel (Camelus dromedarius): Histology and histomorphometry.

This study aims to conduct a comparative analysis of the uterotubal junction in two distinct mammalian species, the bovine (Bos taurus) and the dromedary camel (Camelus dromedarius), focusing on histological and histomorphometric parameters. Uterotubal junction (UTJ) was dissected from 8 cows and 12 camels with dominant follicles, and processed for H&E staining for histology, and histomorphometry examination. The results showed that the camel uterotubal junction papillae (UTJP) existed only in camels and was completely absent in cattle.

Modulation of Apoptosis and Autophagy by Melatonin in Juglone-Exposed Bovine Oocytes.

Melatonin, an antioxidant hormone secreted by the pineal gland, has been recognized as a regulator for numerous biological events. The deleterious effects of juglone, a polyphenolic extract of walnut trees, on embryo development has been previously reported. In the current study, we aimed to display the impact of melatonin administrated during in vitro oocyte maturation (IVM) on juglone-treated oocytes.

Lyophilized equine platelet-rich plasma (L-GF) antagonize the Reproductive toxicity and oxidative stress Induced by Cyclophosphamide in female rats.

Background: The antineoplastic agent Cyclophosphamide (CP) induces reproductive toxicity. New strategies for protecting ovarian tissue damage in women with chemotherapy-induced reproductive toxicity are essential. This study was designed to evaluate the possible protective effect of combined treatment with L-GF on CP-induced reproductive toxicity in the mature female rat.
