Association of pentachlorophenol in urine and follicular fluid with ovarian reserve and reproductive outcomes among women undergoing in vitro fertilization based on a prospective cohort study.

Guangxi Key Laboratory of Environmental Exposomics and Entire Lifecycle Health, School of Public Health, Guilin Medical University, Guilin, 541199, PR China. Electronic address:

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).

Introduction: Human amniotic membrane (hAM) has a highly biocompatible natural scaffold that is abundant in several extracellular matrix (ECM) components, including but not limited to platelet-derived growth factor (PDGF), transforming growth factor (TGF), and fibroblast growth factor (FGF). In our study, we have focused on a mixture of hAM and demineralized bone matrix (DBM) as an allo-hybrid graft to deliver it into the site of bone defect to decrease bone remodeling time.

Methods: Allo-hybrid grafts were prepared by coating the jelly made of decellularized and lyophilized hAM (AMJ) on the surface of DBM and subsequently underwent in vitro studies, such as alkaline phosphatase activity, MTT assay, and SEM analysis.

Purpose: Induction of meiotic competence is a major goal of the controlled ovarian stimulation used in ART. Do factors intrinsic to the oocyte contribute to oocyte maturation? Deletions in mtDNA accumulate in long-lived post mitotic tissues and are found in human oocytes. If oogenesis cleanses the germline of deleterious deletions in mtDNA, meiotically competent oocytes should contain lower levels of mtDNA deletions vs.

ANXA2 promotes chondrocyte differentiation and fracture healing by regulating the phosphorylation of STAT3 and PI3K/AKT signaling pathways.

January 2025

State Key Laboratory of Oral & Maxillofacial Reconstruction and Regeneration, Key Laboratory of Oral Biomedicine Ministry of Education, Hubei Key Laboratory of Stomatology, School & Hospital of Stomatology, Wuhan University, Wuhan, Hubei 430079, China. Electronic address:

Fractures are common and serious skeletal injuries, and accelerating their healing while alleviating patient suffering remains a clinical challenge. Annexin A2 (ANXA2) is a widely distributed, calcium-dependent, phospholipid-binding protein involved in bone remodeling. However, its role in chondrocyte differentiation and endochondral ossification remains unclear.
