Bisphenol A (BPA) has been used since the 1950s, in food packaging, industrial materials, dental sealants, and personal hygiene products. Everyone is exposed to BPA through skin, inhalation, and digestive system. BPA disrupts endocrine pathways, because it has weak estrogenic, antiandrogenic, and antithyroid activities. Despite the rapid metabolism, BPA can accumulate in different tissues. Many researchers proved the impact of BPA on human development, metabolism, and finally reproductive system. There is increasing evidence that BPA has impact on human fertility and is responsible for the reproductive pathologies, e.g., testicular dysgenesis syndrome, cryptorchidism, cancers, and decreased fertility in male and follicle loss in female.

Background: vNOTES has been documented as a viable approach for conducting benign gynecologic surgery; however, its application in ectopic pregnancy cases remains relatively scarce. The principal objective of this investigation was to assess the practicability, effectiveness, and safety of vNOTES in surgical procedures related to ectopic pregnancy.
Methods: Clinical data pertaining to patients diagnosed with ectopic pregnancy at Beijing Hospital between January 2018 and August 2023 were retrospectively collected (This study retrospectively registered with the China Clinical Trial Registry with the registration number ChiCTR2100052223 in September 22, 2021.

Type 2 diabetes mellitus (T2DM) adversely affects various organs, including the brain and its blood barrier. In addition to the brain, hyperglycemia damages the testes. The testes possess blood-tissue barriers that share common characteristics and proteins with the blood-brain barrier (BBB), including breast cancer-resistant protein (BCRP).

In mammalian oocytes, large-scale chromatin organization regulates transcription, nuclear architecture, and maintenance of chromosome stability in preparation for meiosis onset. Pre-ovulatory oocytes with distinct chromatin configurations exhibit profound differences in metabolic and transcriptional profiles that ultimately determine meiotic competence and developmental potential. Here, we developed a deep learning pipeline for the non-invasive prediction of chromatin structure and developmental potential in live mouse oocytes.

Objective: The presence of the microcystic elongated and fragmented (MELF) pattern, distinguished by its microcystic, elongated and fragmented attributes, constitutes a common manifestation of myometrial invasion (MI) within endometrial carcinoma. However, the prognostic significance of this pattern has not been definitively established. Consequently, this research aimed to clarify the prognostic implications of the MELF pattern for individuals diagnosed with endometrial carcinoma.

Breast milk (BM) is the main nutrition source for infants that plays a key role on growth and development. Human milk composition includes endogenous and exogenous substances, including endocrine disrupting chemicals (EDCs). EDCs are man-made environmental chemicals present in everyday environment and food that can disrupt the programming of endocrine signalling pathways during development, resulting in adverse effects that may not be apparent until much later in life.
