Dietary Ergothioneine as a Novel Anti‐Aging Nutraceutical: Mechanisms, Bioavailability, and Future Perspectives

Food Frontiers, Volume 7, Issue 3, May 2026.
ABSTRACT Ergothioneine (EGT), a natural thiol derivative, has gained attention as a geroprotective nutraceutical. Preclinical research shows EGT scavenges free radicals, maintains mitochondrial integrity, slows telomere erosion, and regulates proteostasis via autophagy and senescent cell clearance.

Temperature Dependence of Paramagnetic Species in the Human Brain Tissue: An X‐Band EPR Study

Magnetic Resonance in Medicine, Volume 95, Issue 5, Page 3031-3043, May 2026.
ABSTRACT Purpose Paramagnetic ions are distributed throughout the human brain. The increased accumulation of these metals, such as iron and copper, can induce cellular death and the development of neurological diseases. Electron Paramagnetic Resonance (EPR) is a spectroscopic technique capable of detecting these ions in a given biological sample ...
