BACKGROUND: Infertility remains a global health challenge that often necessitates invasive and costly diagnostic procedures. While the vaginal microenvironment is known to influence reproductive health, its potential as a source of non-inva…

PURPOSE: To identify more reliable tools for embryo selection, this study aimed to investigate whether embryonic kinetic parameters and metabolomic profiling of spent culture medium on D3 can predict subsequent blastocyst development and ch…

Cancer is conventionally viewed as a disease of accumulated somatic mutation and epigenetic dysregulation leading to cell de-differentiation and uncontrolled proliferation. With few exceptions, malignant tumors develop from a single damaged…

Persistent organic pollutants (POPs) are a class of chemical substances with environmental persistence, bioaccumulation, and high toxicity, which are widely present in the environment and food chains. Prostate cancer (PCa) is a highly preva…

Epidemiological inconsistencies currently obscure the causal link between polychlorinated biphenyls (PCBs) and breast cancer. This review synthesizes multi-disciplinary evidence to characterize PCBs not as passive exposure correlates but as…

BackgroundThe copper intrauterine device (Cu-IUD) is a widely used long-term contraceptive method. However, whether prior Cu-IUD use, including long-term exposure, affects reproductive and neonatal outcomes after assisted reproductive techn…

Knee osteoarthritis (KOA) is a highly prevalent chronic degenerative joint disorder characterized by progressive articular cartilage degeneration, chondrocyte death, and extracellular matrix degradation. Accumulating evidence indicates that…

Exosomes, as key mediators of intercellular communication, play a central regulatory role in cellular physiological and pathological processes through their dynamic interaction with the cytoskeleton. The cytoskeleton is a dynamic network co…

Endometrial receptivity (ER) is a pivotal determinant of successful embryo implantation, and its dysfunction is a major cause of infertility and recurrent implantation failure. Mesenchymal stem cells (MSCs) have emerged as a promising thera…

sFRP2, a member of the secreted frizzled-related protein family, is an extracellular protein characterized by a cysteine-rich domain and a netrin-like (NTR) domain. By modulating ligand availability, receptor selection, and microenvironment…

INTRODUCTION: Accurate and non-invasive assessment of early embryonic metabolic biomarkers and their association with developmental potential remains a major challenge in assisted reproductive technology (ART). Glucose is a key metabolic co…

Telomeres are major determinants of chromosome integrity, and when poorly regulated, they have been shown to contribute critically to malignant transformation. However, in gynaecological malignancies, telomeres are interpreted inconsistentl…

OBJECTIVE: To investigate the interaction effects of anti-Müllerian hormone (AMH), antral follicle count (AFC), basal follicle-stimulating hormone (FSH), and endometrial thickness on the outcomes of assisted reproductive technology (ART). …

Follicular development is a complex and dynamic biological process involving coordinated interactions among endocrine regulation, cellular metabolism, redox homeostasis, mitochondrial function, and immune signaling. Increasing evidence indi…

Female reproductive tissues repeatedly undergo controlled inflammation, immune adaptation, and tissue repair. Interleukin-33 (IL-33) and its receptor suppression of tumorigenicity 2 (ST2) sit at the center of these processes, but their role…

Intrauterine adhesion arise from aberrant repair and fibrotic remodeling after basal endometrial injury. Hysteroscopic adhesiolysis remains the standard treatment, yet postoperative recurrence stays high and durable preventive strategies re…

As a major global health threat, tumors present significant clinical challenges due to their heterogeneity, metastatic potential, and therapy resistance. In recent years, non-coding RNAs, particularly microRNAs (miRNAs), have emerged as cru…

Despite major advances in oncology, cancer therapy continues to face persistent challenges due to intratumoral heterogeneity, drug resistance, and the poor clinical translation of experimental therapeutics. Conventional preclinical models s…

BACKGROUND: Endometrial thickness (EMT) is a crucial indicator of endometrial receptivity in assisted reproductive technology (ART). However, its relationship with pregnancy outcomes remains unclear, especially across different cycle types …

The endocrine functions exerted by ovarian granulosa cells (GCs) are crucial factors in maintaining follicle development, as oocyte development relies on providing energy substrates and cytokines by ovarian granulosa cells. The mRNA deadeny…

IntroductionCarnitine palmitoyltransferase 1A (CPT1A) is crucial for mitochondrial function, and its dysfunction has been linked to the development of several diseases. However, the role of CPT1A in severe acute pancreatitis (SAP) and its u…

Liver fibrosis is induced by persistent stimulation of various factors, resulting from complex multicellular interactions and multifactorial networks. Without intervention, it can progress to cirrhosis and even liver cancer. Current underst…

Aberrant interactions among decidual stromal cells, decidual natural killer (dNK) cells, and trophoblasts are implicated in placenta accreta spectrum (PAS) pathogenesis, though the underlying mechanisms remain unclear. This study investigat…

INTRODUCTION: A transient window of uterine receptivity ensures that embryos implant in an optimal endometrial environment. Failure to establish or premature closure of the implantation window is thought to be a major cause of infertility, …

tRNA-derived small RNAs (tsRNAs) are a class of non-coding RNAs(ncRNAs) generated from precursor or mature tRNAs under stress conditions, such as starvation, hypoxia, or oxidative stress. They are broadly classified into a growing class of …
