The role of sleep in chronic fatigue syndrome

Poor quality and unrefreshing sleep is one of the most common symptom complaints in Chronic Fatigue Syndrome (CFS). Despite this, the links between sleep dysfunction and CFS are not well understood, and there has been an absence of good quality research ...

An Energy Autonomous Microneedle Array‐Based Sensing System for Continuous Biomarker Monitoring

Advanced Science, EarlyView.
This work presents an innovative self‐powered wearable biosensor system for real‐time monitoring of multiple biomarkers in interstitial fluid. The device integrates stainless steel‐based minimally invasive microneedles with ion‐selective membranes, enabling simultaneous Na+, K+, Ca2+, pH, and glucose detection.

SuFEx‐Enabled Reprogramming of Flavonoids for Selective α‐Glucosidase Covalent Inhibition

Advanced Science, EarlyView.
Selective inhibition of intestinal α‐glucosidase remains limited by poor enzyme specificity and off‐target metabolic effects. Here, SuFEx click chemistry is used to reprogram natural flavonoids into covalent inhibitors with enhanced α‐glucosidase selectivity and controlled reactivity. This strategy enables effective regulation of carbohydrate digestion
