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 ...

A Review of Vagus Nerve Stimulation for Disease: Comprehensive Theory and Evidence for Mechanisms of Action

Comprehensive Physiology, Volume 16, Issue 2, April 2026.
Vagus nerve stimulation (VNS) effects span central and peripheral organ systems through diverse mechanistic pathways. This comprehensive review provides a unified synthesis of these mechanisms across neurological, cardiovascular, immunological, metabolic, and gastrointestinal domains, filling a critical gap and serving as a foundational resource for ...

Effects of L‐Tyrosine Ingestion on Endurance Performance in Mentally Fatigued Cyclists

European Journal of Sport Science, Volume 26, Issue 4, April 2026.
ABSTRACT This study investigated whether L‐tyrosine supplementation enhances endurance performance in mentally fatigued cyclists. Twelve recreational cyclists completed two constant‐workload tests to exhaustion cycling tests under two experimental conditions at 80% of maximal endurance power output: L‐tyrosine ingestion (300 mg/kg) under mental fatigue

Mapping Intracellular Volume Fraction With Susceptibility Source Decomposition as a Marker for Tissue Cellularity

Journal of Magnetic Resonance Imaging, Volume 63, Issue 4, Page 1092-1105, April 2026.
ABSTRACT Background Pathophysiological changes affect tissue cell composition and density. For example, neurodegenerative disorders and brain tumors are associated with cell loss and abnormal accumulation, respectively. In these scenarios, if monitored and tracked, tissue cellularity might be used to inform clinical diagnosis and management. Purpose To
