Move beyond free radical theory of aging

open access: yesiMetaOmics, Volume 3, Issue 1, March 2026.
Free radicals play a dual, dose‐dependent role in aging. Low levels activate the key sensor adenosine 5'‐monophosphate‐activated protein kinase (AMPK), promoting cell survival mechanisms like autophagy and enhancing mitochondrial health. High levels, however, push AMPK to initiate cell death pathways, such as apoptosis. This positions AMPK as a central

NAD+ Enhanced on Hearing Recovery in Sudden Sensorineural Hearing Loss: Randomized Controlled Trial

open access: yesThe Laryngoscope, Volume 136, Issue 3, Page 1204-1214, March 2026.
This 2‐year, single‐center, double‐blind study with a small sample size compared NAD+ and control groups in a randomized controlled trial for sudden sensorineural hearing loss (SSNHL). Results showed that NAD+ led to better hearing improvement from 7 days to 3 months and a shorter average recovery time compared to the control group.
