Early Pregnancy Oxylipins Point to Distinct Inflammatory and Oxidative Stress Signals in Fetal Growth Restriction

By MedXY|Aug 18, 2026

Early pregnancy urinary oxylipins linked inflammatory and oxidative stress pathways to small-for-gestational-age birth, with distinct signatures for early- and late-onset growth restriction. Associations with large-for-gestational-age birth

Red Blood Cell Metabolism Modulates Muscle Oxygenation and Limits Exercise Capacity: Insights from a Randomized Double‑Blind Crossover Study

By MedXY|Nov 4, 2025

A randomized crossover study in 20 men shows exercise‑induced oxidative stress alters erythrocyte redox and glycolytic metabolism, reduces 2,3‑BPG/ATP generation, and modestly impairs muscle oxygen extraction and arm exercise VO2peak, sugge

High-Protein Diet and Strength Training in Older Adults: No Adverse Impact on Oxidative Stress Markers

By MedXY|Oct 8, 2025

A 17-week randomized controlled trial demonstrates that a high-protein diet combined with strength training does not negatively affect oxidative stress markers in older adults, supporting their safe use to combat sarcopenia.
