Highly Sensitive and Selective Colorimetric Sensing of Hg2+ Based on the Morphology Transition of Silver Nanoprisms

, 2013
A simple colorimetric approach for mercury ion (Hg2+) sensing was developed that was based on the Hg2+. induced deprotection and morphology transition of 1-dodecanethiol (C12H25SH)-capped silver nanoprisms (Ag NPRs) upon the presence of iodides at room ...

ALDOA Promotes Glycolysis and NLRP3/GSDMD Pyroptosis to Accelerate ALS Progression

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Amyotrophic lateral sclerosis (ALS) is characterized by progressive motor neuron degeneration. Glycolytic dysregulation is implicated in disease progression, yet the underlying mechanisms remain unclear. This study investigates how Aldolase A (ALDOA) drives ALS progression through glycolysis‐mediated motor neuron pyroptosis.
