Intermittent fasting reshapes the gut microbiota in diabetic cardiomyopathy, restoring Akkermansia muciniphila and the microbiota‐associated metabolite 1‐methyl‐L‐histidine. This shift is linked to improved cardiac lipid homeostasis, reduced lipid peroxidation, and attenuated myocardial injury, highlighting a gut microbiota–metabolite–lipid axis in ...

Vapor Jet Ejector Used To Generate Free Waste Heat Driven Cooling In Military Environmental Cooling Units [PDF]
The waste heat driven vapor jet ejector cooling cycle is a very promising approach to produce ‘free’ cooling by utilizing low-grade energy sources. The mechanism behind ejector-based waste heat cooling is very different from absorption or adsorption ...

Photo‐Gated Corona Microfluidics
Photo‐gated corona microfluidics decouples optical programming from electric‐field actuation to enable reconfigurable manipulation on open, electrode‐pattern‐free surfaces. Near‐infrared irradiation locally melts paraffin, creating a reversible charge‐relaxation pathway that reconstructs the electric field.

Nanoparticle‐Mediated Bubble Suppression During Droplet Solidification for Mechanical Reinforcement
Nanoparticles mediate droplet solidification by raising nucleation temperature, refining dendrites, and slowing freezing‐front advance, thereby suppressing trapped air bubbles in droplet‐based 3D printing. This strategy reduces bubble volume fraction by ∼35% and increases compressive strength by up to 39%, offering a low‐cost route to stronger printed ...

A Novel Pak1 Activator Ameliorates ER Stress for HFpEF Therapy
Chronic metabolic stress is a major contributor to HFpEF progression. Under prolonged metabolic stress, Pak1 activity becomes impaired, contributing to disrupted ER proteostasis, cardiomyocyte apoptosis, fibrosis, and diastolic dysfunction. Mechanistically, Pak1 overexpression activates the ERK1/2–MNK1–eIF4E signaling axis, promotes translational ...
