«Edge-to-edge» mitral valve repair for septal myectomy versus isolated myectomy: a pilot randomized trial

Евразийский Кардиологический Журнал, 2023
Background. Septal myectomy  is currently the «gold» standard of surgical treatment  of patients with obstructive  hypertrophic  cardiomyopathy.  In some  cases,  isolated septal myectomy does  not eliminate SAM-induced mitral insufficiency.

SemanticST: A Scalable Multi‐Contextual Graph Learning Framework for Uncovering Spatial Niches and Robust Multi‐Sample Integration in Spatial Transcriptomics

Advanced Science, EarlyView.
Technical limitations often let dominant signals overshadow rare cell types and fine‐grained heterogeneity in spatial transcriptomics. SemanticST, a graph neural network using multi‐semantic graph fusion and a novel min‐cut loss, recovers these subtle patterns.

The Deubiquitinase UCHL1 Drives Susceptibility to Atrial Fibrillation by Stabilizing CaMKII‐δ

Advanced Science, EarlyView.
UCHL1 is highly upregulated in mice and patients with AF. UCHL1 directly binds to and removes K48‐linked polyubiquitin chains from CaMKII‐δ at K251 and enhances CaMKII‐δ stability, which activates RyR2, disrupts Ca2+ handling, and promotes AF. These findings establish UCHL1 as a critical regulator of CaMKII‐δ stability and AF‐related Ca2+ handling ...
