Single‐Nucleus Atlas of Spinal Sarcopenia Patients Reveals Disruption of Quiescent and Regenerative Satellite Cell Niches in Fatty‐Infiltrated Muscle

Advanced Science, EarlyView.
Mechanisms of Fatty Infiltration and Muscle Degeneration. Clinical metadata identified intramuscular fat accumulation as an independent driver of muscle mass decline. Single‐nucleus RNA sequencing of spinal sarcopenia muscle revealed adipogenic reprogramming of fibro‐adipogenic progenitors, satellite‐cell niche disruption, and elevated levels of the ...

Association of Neutrophil-to-Lymphocyte Ratio with Severity of Coronary Artery Disease in Patients Undergoing Coronary Angiography

Current Clinical and Medical Education
Background: Coronary artery disease (CAD) remains the leading cause of global mortality. The neutrophil-to-lymphocyte ratio (NLR), derived from routine blood counts, is a simple inflammatory index. Its correlation with angiographic CAD severity in Indian

Improving High‐Temperature Operational Stability of Inverted Perovskite Solar Cells Through MXene Heat‐Dissipating Layers

Advanced Science, EarlyView.
MeO‐2PACz‐functionalized MXene nanosheets create a thermally conductive buried interface in inverted perovskite solar cells. The interface improves heat spreading, suppresses defects and ion migration, and strengthens charge extraction, extending T80 at 65°C from 141 to 687 h while maintaining competitive efficiency.

A Novel Cooling System for High-Speed Axial-Flux Machines Using Soft Magnetic Composites

Energies
Demand is high for small, lightweight, and power-dense machines. However, as power increases and size decreases, rejecting losses becomes more difficult. Many novel cooling systems have been developed, which have allowed machines to be made smaller while
