BACKGROUND: Postmenopausal women are at elevated risk for carotid atherosclerosis due to estrogen decline, yet existing prediction models do not incorporate genetic markers. This study aimed to develop and validate a risk prediction model c…

BACKGROUND: Embryo implantation failure and early pregnancy loss remain significant challenges in assisted reproductive technology (ART). Lipid peroxidation is known to be involved in reproductive physiology. However, its role during the im…

Biomarkers play a pivotal role in contemporary medical research, particularly in the early diagnosis of diseases and personalized treatment. Although previous studies have systematically reviewed markers across various disease domains, an i…

The purpose of this meta-analysis was to systematically assess the efficacy of ultrasound-guided therapy of ovarian endometriosis cyst (OEC). Several databases were searched to gather published studies on the efficacy of ultrasound-guided t…

This study investigates the molecular mechanism by which USP25 contributes to pancreatic microcirculatory disturbance in severe acute pancreatitis (SAP). SAP was induced by retrograde injection of 4% sodium taurocholate into the pancreatic …

OBJECTIVES: Obesity and endometriosis are intricately linked. The body mass index (BMI) is commonly used as an indicator of obesity, but it has limitations. The visceral adiposity index (VAI) is a novel, low-cost composite index that reflec…

OBJECTIVE: The association between anti-Müllerian hormone (AMH) levels and embryonic aneuploidy rates was investigated by analyzing clinical and embryo laboratory data from patients with preimplantation genetic testing for aneuploidy (PGT-A…

BACKGROUND: Gonadotropin-releasing hormone (GnRH) antagonist and long-acting GnRH agonist regimens are commonly employed for ovarian stimulation in women undergoing in-vitro fertilization (IVF)/intracytoplasmic sperm injection (ICSI), but t…

Defective endometrial receptivity represents an important factor in recurrent implantation failure (RIF), though its precise regulatory mechanisms remain unclear. While nicotinamide N-methyltransferase (NNMT) is abundantly expressed in huma…

BACKGROUND: Breast cancer (BC) continues to be a predominant cause of cancer-related deaths among women globally, highlighting the complexity of the disease, its propensity for metastasis, and resistance to conventional therapies. The disco…

Endothelial-mesenchymal transition (EndMT) is a biological process in which endothelial cells lose intercellular junctions and endothelial characteristics under specific pathophysiological stimuli and acquire mesenchymal traits. It plays a …

BACKGROUND: Idiopathic pulmonary fibrosis (IPF), a relentlessly progressive lung disorder marked by unremitting extracellular matrix deposition, continues to challenge clinical management due to its enigmatic etiology. Emerging evidence pos…

A considerable number of women of reproductive age suffer from endometriosis worldwide. There is a significant physical, mental, and financial burden on patients affected by this condition in terms of pelvic pain, either continuously or int…

OBJECTIVE: Polycystic ovary syndrome (PCOS) is a reproductive endocrine disease characterized by reproductive dysfunction and metabolic abnormalities. The purpose of this study was to explore the expression characteristics of coding and non…

Heterogeneous cancer-associated fibroblasts (CAFs) play important roles in cancer progression. However, the specific biological functions and regulatory mechanisms involved in endometrial cancer have yet to be elucidated. We aimed to explor…

INTRODUCTION: This study aimed to investigate the microbial characteristics of yak uteri collected using intrauterine cotton swabs (CS) during different reproductive stages and the correlation of these microbial characteristics with reprodu…

PURPOSE: Multiple factors have been shown to influence the rate of clinical pregnancy after FET in IVF treatment, including embryo quality, synchronization of embryo and endometrium, and endometrial receptivity (ER). The subendometrial bloo…

BACKGROUND: The aim of the retrospective cohort study was to investigate the prognostic effect of subchorionic hematomas (SCH) in the first trimester on pregnancy outcomes after euploid embryo transfer. METHODS: We retrospectively analyzed…

BACKGROUND: The association of dyslipidemia with embryo development and pregnancy outcomes is largely unknown, especially in unexplained recurrent implantation failure (uRIF) patients. Here, this study aimed to explore the impact of abnorma…

Understanding the microflora inhabiting the reproductive tract is important for a better understanding of female physiology and reproductive health. The endometrial fluid from mice in three reproductive stages (A: Unproductive mice; B: Post…

AIM: To compare the pregnancy outcomes of frozen-thawed embryo transfer (FET) cycles among women with repeated implantation failure (RIF) treated with various endometrial preparation protocols. METHODS: A total of 605 women with RIF were r…

IMPORTANCE: Implantation failure remains a critical barrier to in vitro fertilization. Prednisone, as an immune-regulatory agent, is widely used to improve the probability of implantation and pregnancy, although the evidence for efficacy is…

Fungal populations are commonly found in natural environments and present enormous health care challenges, due to increased resistance to antifungal agents. Paeonol exhibits antifungal activities; nevertheless, the antifungal and antibiofil…
