Disrupting stroke-induced GAT-1-syntaxin1A interaction promotes functional recovery after stroke.

Although stroke is a frequent cause of permanent disability, our ability to promote stroke recovery is limited. Here, we design a small-molecule stroke recovery promoting agent that works by dissociating γ-aminobutyric acid (GABA) transporter 1 (GAT-1) from syntaxin1A (Synt1A), a soluble N-ethylmaleimide-sensitive factor attachment protein receptor (SNARE) protein. Stroke induces an increase in GAT-1-Synt1A interaction in the subacute phase, a critical period for functional recovery.

Arthroscopic Anterior Cruciate Ligament Avulsion Fixation With a Knotless Suture Anchor: A Minimalistic Approach.

This technical note outlines a minimalist arthroscopic approach to anterior cruciate ligament avulsion fracture fixation using a bioabsorbable knotless suture anchor. This method represents a less invasive alternative to traditional techniques, catering specifically to fractures classified as Meyers and McKeever type II or III. The procedure is performed through standard anterolateral and anteromedial portals without the need for additional incisions or bone tunnel drilling, making it particularly suitable for children and adolescent patients with open physes.

CellContrast: Reconstructing spatial relationships in single-cell RNA sequencing data via deep contrastive learning.

A vast amount of single-cell RNA sequencing (SC) data have been accumulated via various studies and consortiums, but the lack of spatial information limits its analysis of complex biological activities. To bridge this gap, we introduce CellContrast, a computational method for reconstructing spatial relationships among SC cells from spatial transcriptomics (ST) reference. By adopting a contrastive learning framework and training with ST data, CellContrast projects gene expressions into a hidden space where proximate cells share similar representation values.
