Xanthine urolithiasis.

open access: yesSaudi journal of kidney diseases and transplantation : an official publication of the Saudi Center for Organ Transplantation, Saudi Arabia, 2010
Hereditary xanthinuria type I, a defect of purine metabolism, results from a genetic deficiency of xanthine oxidase. It is an uncommon cause of stone formation in children. We report here two children with xanthine urolithiasis. The first patient was an 8-year-old boy who presented with repeated episodes of hematuria evaluated with excretory urography,

Single‐Cell Transcriptomics and Metabolomics Reveal Glutamate Dehydrogenase as a Central Regulator of Nitrogen Metabolic Remodeling During Alkalinity Adaptation in Crustaceans

open access: yesAdvanced Science, EarlyView.
Single‐cell transcriptomics reveals the cellular response of Macrobrachium hainanense to carbonate alkalinity stress. Alkalinity stress impairs branchial ammonia excretion, induces mitochondrial dysfunction, and drives cell‐type‐specific changes in gills and hemocytes.
