FABP4 as a Mediator of Lipid Metabolism and Pregnant Uterine Dysfunction in Obesity
Advanced Science, EarlyView.Obesity during late pregnancy contributes to uterine smooth muscle dysfunction, but the underlying mechanisms are unclear. This study identifies fatty acid binding protein 4 (FABP4) as a key player in the process, mediating excessive fatty acid uptake, lipid accumulation, and mitochondrial dysfunction in myometrial cells. FABP4 could be a novel uterine

Advanced Electronic Materials, EarlyView.In this study, a novel 1D lead‐free metal halide, K2CuBr3, composed of earth‐abundant elements, is introduced for resistive switching and artificial synapse devices. With exceptionally low production costs and minimal environmental impact, K2CuBr3 can be a promising candidate for sustainable memory storage and neuromorphic computing.

Advanced Energy Materials, EarlyView.Pt/C catalysts differing only in the locality of the Pt nanoparticles, whether inside or outside of the pores of the same carbon support, are needed to study the effect of said locality. Depending on the carbon support used, nanoparticles inside the pores can show hindered accessibility and ORR performance.
