Kidney Stone Dissolution By Tetherless, Enzyme‐Loaded, Soft Magnetic Miniature Robots

Advanced Healthcare Materials, Volume 14, Issue 23, September 8, 2025.
Wireless magnetic robots are developed for kidney stone dissolution. The robots navigate through a urinary tract model from bladder and ureter to renal pelvis with the help of external magnetic fields. The filaments are loaded with urease enzyme which catalyzes urea to carbon dioxide and ammonia, thereby increasing pH to basic regime and supporting ...

Zinc Alleviates Gut Barrier Dysfunction by Promoting the Methylation of AKT

Advanced Science, Volume 12, Issue 33, September 4, 2025.
Zinc activates the ZNG1‐METAP1 complex to elevate intracellular SAM levels, which promotes PRMT5‐mediated symmetrical dimethylation of AKT at R391 and R15. This epigenetic modification facilitates AKT membrane translocation and mTORC2 activation, thereby enhancing epithelial proliferation and gut barrier integrity.

Case Report: Unusual Neurological Features of Leigh Syndrome due to m.8993T>G Pathogenic Variant in the MT‐ATP6 Gene

American Journal of Medical Genetics Part A, Volume 197, Issue 9, September 2025.
ABSTRACT The MT‐ATP6 gene m.8993T>G pathogenic variant has been associated with Leigh syndrome, especially in patients exhibiting a high degree of heteroplasmy. Although patients may present with a wide phenotypic spectrum, characteristic findings include bilateral, symmetric hyperintensities in the basal ganglia and brainstem on brain MRI ...
