l-carnitine transports fatty acids into mitochondria mechanism Carnitine Shuttle Carnitine Shuttle - an overview

MTs bind up to seven zinc ions per molecule via thiolate clusters formed by their 20 cysteine residues, exhibiting high thermodynamic stability and kinetic lability, enabling rapid zinc exchange

To overcome these limitations, in this study, we describe the rational design, synthesis, and in-depth biological assessment of ruthenium (Ru)-containing nanoreactors for the catalytic oxidation of GSH to GSSG in hypoxic osteosarcoma

Key physiological features of the hypothalamo-pituitary-adrenal (HPA) axis are discussed, including the ultradian pulsatility of CRH, AVP and ACTH secretion, the circadian pattern of secretion, the negative feedback of cortisol on the HPA axis, the stress response, and the effects of aging and gender

Stretch marks are linear bands that form when the skin is stretched beyond its capacity, causing the dermis (middle layer of skin) to tear
