Detection Limits of Blood Metabolites at Physiological Concentrations Using Benchtop 1$$ {}^1 $$H NMR

NMR in Biomedicine, Volume 39, Issue 2, February 2026.
We demonstrate rapid, sensitive detection of key blood metabolites using an 80 MHz low‐field NMR spectrometer, benchmarking signal‐to‐noise ratios and acquisition efficiency across experimental designs. Millimolar metabolites such as glucose and lactate are reliably detected and quantified within seconds, while simulation‐assisted spectral fitting ...

Role of Acid‐Sensing Ion Channels 1a in the Regulation of Obesity and the Gut Microbiota

Obesity, Volume 34, Issue 2, Page 372-381, February 2026.
ABSTRACT Objective Acid‐sensing ion channels are proton‐activated ion channels predominantly found in the nervous system. They are well known to affect metabolic and neurological health, yet their role in obesity and gut physiology remains unclear. This study investigates how systemic deletion of Asic1a influences obesity, metabolic, and gut‐based ...
