3D Printed High‐Strength Hydrogel for Dual Release of Cu2+ and Ag+ Ions to Enhance Bone Repair and Antibacterial Properties

open access: yesRare Metals, Volume 45, Issue 6, June 2026.
ABSTRACT Bone restoration is often hindered by the spatiotemporal dysregulation of immune and regenerative signals. Conventional bio‐inert implants, providing only passive support, fail to modulate this microenvironment, leading to infections and poor healing.

Lipid Nanoparticles Delivering ClpP‐mRNA Suppress Pyroptosis and Senescence in Intervertebral Disc Degeneration via mTOR/BNIP3‐Activated Mitophagy

open access: yesRare Metals, Volume 45, Issue 2, February 2026.
ABSTRACT Intervertebral disc degeneration (IDD) is a predominant cause of low back pain, significantly impacting quality of life. Mitochondrial fitness is essential in the progression of IDD, as it regulates cellular senescence and pyroptosis. This study investigates the role of mitochondrial caseinolytic protease P (ClpP) in alleviating senescence and

人肝癌胞浆蛋白质双向电泳的研究

open access: yesZhongshan Daxue xuebao. Yixue kexue ban, 1988
用高分辨率的蛋白质双向电泳对人肝癌及正常肝组织的胞浆蛋白质进行检测。结果表明肝细胞癌变后,胞浆蛋白质双向电泳图谱发生了显著改变,总点数增加,蛋白质点的分布向低分子量低等电点偏移,出现了一些新的蛋白质点,有些蛋白质点密度增加,有些蛋白质点密度减少或消失。

SWEET1‐mediated glucose transport is crucial for energy availability in Arabidopsis

open access: yesNew Phytologist, Volume 249, Issue 4, Page 1816-1830, February 2026.
Summary The stress‐responsive hormone abscisic acid (ABA) is known for its inhibitory effects on various physiological processes, including seed germination, often resulting in energy deprivation. Interestingly, ABA‐induced germination inhibition can be alleviated by exogenous glucose (Glc), mimicking a functional interplay between ABA and sugar ...
