Notoginsenoside R2 Antagonizes Renal Interstitial Fibrosis by Regulating Fatty Acid Oxidation via the CASP2/ALDH3A1 Axis

open access: yesPhytotherapy Research, EarlyView.
Proposed mechanism by which notoginsenoside R2 (NGR2) attenuates renal interstitial fibrosis. In injured renal tubular epithelial cells, CASP2 downregulation and enhanced ubiquitin‐dependent degradation of ALDH3A1 disrupt mitochondria‐associated endoplasmic reticulum membranes (MAMs) and impair fatty acid oxidation (FAO), leading to lipid accumulation ...

Rational Design Strategies Toward Efficient and Stable Electrocatalysts for Hydrogen Production via Water Electrolysis: A Comprehensive Review

open access: yesSmall, EarlyView.
ABSTRACT Active and stable electrocatalysts are critical for sustainable hydrogen production, particularly for high‐current‐density water electrolysis and specialized applications like seawater splitting. However, most water‐splitting electrocatalysts show limited activity at high current densities and poor long‐term stability, making it difficult to ...

Nanopore and Self‐Assembled Monolayer Engineering of l‐Lactate Oxidase Gold Electrodes for Enhanced l‐Lactate Biosensing

open access: yesSmall, EarlyView.
A tiered nanoporous gold biointerface enables site‐directed immobilization of His‐tagged lactate oxidase through a mixed self‐assembled monolayer, achieving high enzyme loading while preserving activity. The resulting bioelectrode provides sensitive and stable l‐lactate detection (0.12–3.0 mM, 75 µA mM−1 cm−2), demonstrating a modular strategy for high‐

Quantitative Imaging of Water Diffusion in Brain Parenchyma at Cellular Resolution Using Stimulated Raman Scattering Microscopy

open access: yesSmall, EarlyView.
A multimodal multiphoton imaging framework enables high‐resolution quantification of water diffusion in brain tissue. By tracking deuterated water via stimulated Raman scattering (SRS) microscopy, this study resolves the microscopic heterogeneity of water diffusion at cellular resolution and determines apparent diffusion coefficients in health and ...

Cardiomyocyte Membrane‐Camouflaged Spinach Nano‐Thylakoids Enhance Myocardial Energy Metabolism and Ameliorate Heart Failure

open access: yesSmall, EarlyView.
Schematic illustration of the construction of MM‐NTU, its cardiac‐targeting behavior, and its light‐activated therapeutic mechanism. Thylakoids isolated from spinach chloroplasts were processed into nano‐thylakoid units (NTU) and further camouflaged with cardiomyocyte membranes to generate MM‐NTU.

Progress in bone tissue engineering biomaterials: Development, challenges, and prospects

open access: yesVIEW, EarlyView.
Scheme 1 Application of biomaterials in immunomodulation during bone tissue engineering. Abstract Bone defect repair remains a major clinical challenge in orthopedics. Over 2 million cases caused by trauma, tumors, and other factors occur annually, with large‐scale defects posing a particular bottleneck due to limited self‐healing capacity.
