Telomere attrition is a hallmark of biological aging, contributing to cellular replicative senescence. However, few studies have examined the determinants of telomere attrition in vivo in humans. Mitochondrial Health Index (MHI), a composite marker integrating mitochondrial energy-transformation capacity and content, may be one important mediator of telomere attrition, as it could impact telomerase activity, a direct regulator of telomere maintenance.

Mammalian reproduction requires that nursing mothers transfer large amounts of calcium to their offspring through milk. Meeting this demand requires the activation of a brain-breast-bone circuit during lactation that coordinates changes in systemic hormones, dietary calcium intake, skeletal turnover, and calcium transport into milk. Classically, increased bone resorption via increased parathyroid hormone-related protein and low estrogen levels is the main source of calcium for milk production during lactation.

Long non-coding RNAs (lncRNAs) have emerged as crucial regulators in cancer progression. We found lncRNA DNM1P35 is elevated in ovarian tumors compared to normal tissues, and demonstrated that lncRNA DNM1P35 promoted cancer cell proliferation, migration and invasion in SK-OV-3 and OVCAR-3 cell lines. Furthermore, lncRNA DNM1P35 also facilitated the epithelial-mesenchymal transition (EMT) of ovarian cancer cells.

Ischemia and hypoxia caused by vascular injury intensify nerve damage. Skin precursor-derived Schwann cells have demonstrated an accelerated in vivo pre-vascularization of tissue-engineered nerves. Furthermore, extracellular vesicles from skin precursor-derived Schwann cells (SKP-SC-EVs) show the potential in aiding peripheral nerve regeneration.

Dibutyl phthalate (DBP) is a low-molecular-weight phthalate commonly found in personal care products, such as perfumes, aftershaves, and nail care items, as well as in children's toys, pharmaceuticals, and food products. It is used to improve flexibility, make polymer products soft and malleable, and as solvents and stabilizers in personal care products. Pregnancy represents a critical period during which both the mother and the developing embryo can be significantly impacted by exposure to endocrine disruptors.
