Menopausal hormone therapy slashes low bone density risk by 69%
A retrospective analysis shows that women on menopausal hormone therapy experience a 69% lower risk of developing low bone mineral density compared with those not receiving therapy. The finding highlights hormone treatment as a potentially powerful tool for preserving skeletal health during menopause.
Injectable Mini-Livers as an Alternative to Liver Regeneration
Researchers have introduced INSITE, an injectable platform that combines primary human hepatocytes with hydrogel microspheres to form self‑assembling, vascularizable tissue ensembles in situ. Using ultrasound guidance, the scaffold is delivered to an ectopic site where it integrates with host vasculature and maintains long‑term hepatic function. This minimally invasive approach sidesteps the need for whole‑organ transplantation and addresses low engraftment rates that have hampered previous cell‑based therapies. Early animal data show persistent imaging visibility and functional liver activity at the graft site.
Pre‑exhaustion Offers No Advantage over Straight Sets
