January 2025
Department of Veterinary Medicine, University of Sassari, Via Vienna 2, Sassari, Italy.
Purpose: This study aimed to evaluate the effectiveness of single versus group culture strategies for cumulus-oocyte complexes (COCs) derived from early antral follicles (EAFs), with the goal of optimizing culture conditions to increase oocyte availability for assisted reproductive technologies.
Methods: COCs isolated from EAFs (350-450 µm) from sheep ovaries were cultured in TCM199 medium supplemented with 0.15 µg/mL Zn as zinc sulfate, 10 IU/mL FSH, 10 ng/mL estradiol, 50 ng/mL testosterone, 50 ng/mL progesterone, and 5 µM Cilostamide.
Effect of estrogen on myocardial ischemia-reperfusion injury in male and female rats and related mechanism.

Due to the difference of estrogen levels in different phases of estrous cycle, it is necessary to exclude the influence of endogenous estrogen when studying the cardiovascular effects of estrogen and its analogues. In this study, the ischemia/reperfusion (I/R) injury of isolated heart were investigated in female rats during different phases of estrous cycle with male rats as comparison. The results indicated that the estrogen content in blood of rats during metestrus and diestrus (MD) was lower than those during proestrus and estrous (PE).

Background: Heart failure is linked to increased hospitalization and mortality. Mitochondrial permeability transition-driven necrosis is associated with cardiovascular diseases, but its role in heart failure is unclear. This study aimed to identify and validate genes related to mitochondrial permeability transition-driven necrosis in heart failure, potentially leading to new drug targets and signaling pathways.

Hormonal contraceptives may influence HPV acquisition, persistence, and clearance, but evidence remains inconclusive. This sub-study aimed to evaluate the impact of different hormonal contraceptives on HPV prevalence and genotype distribution in AGYW.

Pentachlorophenol (PCP), a persistent organic pollutant, has endocrine disrupting properties and there may be a link between its exposure and reproductive outcomes. In this study, we assessed the relationship of PCP exposure levels with ovarian reserve markers and reproductive health outcomes in women (N = 656) undergoing in vitro fertilization (IVF). PCP concentrations were determined in urine (n = 1,968; repeated measures) and follicular fluid samples (n = 603).
