Association Between Intermittent Fasting and Susceptibility‐Weighted MRI Phase Values in Deep Gray Matter of Patients With Multiple Sclerosis: An Observational Cohort Study

Mahmoud R. Hamed, Yasser F. Ali, Mahmoud A. Kenawy, Mohamed El-Samahy et autres

BACKGROUND: One manifestation of multiple sclerosis (MS) is abnormal iron-related susceptibility changes in deep gray matter (DGM), contributing to oxidative stress and neurodegeneration. Intermittent fasting (IF) is a metabolic intervention that may influence inflammatory and iron-related pathways. PURPOSE: To compare susceptibility-derived phase …

0.5 Gy confers resistance to a subsequent high dose of γ-rays by modulating HO-1/Nrf2 and apoptosis pathways

Yasser F. Ali, Hussein M. Abdelhafez, Omar S. Desouky

Ionizing radiation, from the DNA centric view, elicits biological effects and health consequences solely through energy deposition events in the cell nucleus. At higher radiation doses, this is likely true; however, at low doses, non-targeted effects, a subcategory of which is the …

Biological Effects of Space Hypomagnetic Environment on Circadian Rhythm

Xunwen Xue, Yasser F. Ali, Wanrong Luo, Caorui Liu et autres

The intrinsic earth magnetic field (geomagnetic field, GMF) provides an essential environmental condition for most living organisms to adapt the solar cycle by rhythmically synchronizing physiological and behavioral processes. However, hypomagnetic field (HMF) of outer space, the Moon, and the Mars differs …
