Waveguide Photoactuators: Materials, Fabrication, and Applications

Advanced Robotics Research, EarlyView.
Waveguide photoactuators convert guided light into mechanical motion. Their tethered‐flexible design enables minimally invasive surgery and confined‐space robotics. This review aims to guide materials selection, device design, and system integration, accelerating the transition of waveguide photoactuators from laboratory prototypes to versatile ...

Determination of Gene‐Level Fitness Contributions Across the Mucin‐Utilization Network of Bacteroides thetaiotaomicron

Advanced Science, EarlyView.
Genome‐wide CRISPRi and RNA‐seq resolve how B. thetaiotaomicron converts host mucosal glycans into fitness. The study reveals a layered mucin‐utilization architecture in which capsular polysaccharides constrain surface access, extracellular CAZymes and peptidases show functional redundancy, and intracellular catabolic pathways create discrete metabolic

Indirect Quantification of Glyphosate by SERS Using an Incubation Process With Hemin as the Reporter Molecule: A Contribution to Signal Amplification Mechanism

Frontiers in Chemistry, 2020
The indirect determination of the most used herbicide worldwide, glyphosate, was achieved by the SERS technique using hemin chloride as the reporter molecule.

Hemin treatment drives viral reactivation and plasma cell differentiation of EBV latently infected B cells.

PLoS Pathogens, 2023
Epstein-Barr virus (EBV) and Plasmodium falciparum have a well described role in the development of endemic Burkitt lymphoma (BL), yet the mechanisms involved remain unknown.

C1qc Mediates Blood–Brain Barrier Disruption in a Mouse Model of Intracerebral Haemorrhage Through Microglia‐Derived Migrasomes [PDF]

J Extracell Vesicles
Microglia‐derived migrasomes induce vascular endothelial pyroptosis through C1qc delivery, uncovering a novel mechanism of blood–brain barrier (BBB) disruption after intracerebral haemorrhage (ICH) and proposing a novel therapeutic strategy targeting extracellular vesicles (EVs).

Glycopolymeric nanoparticles transported by activated platelets protect ischemic myocardium by alleviating PANoptosis through targeting macrophage Dectin‐1

BMEMat, EarlyView.
NP‐SF, designed to target macrophage Dectin‐1 and activated platelets, selectively accumulated in ischemic myocardium, where it was taken up by macrophages after platelet hitchhiking. By inhibiting NLRC5‐related PANoptosis, NP‐SF significantly attenuated pathological damage, and effectively preserved cardiac function in a murine ischemia–reperfusion ...

Inhibitory Effect of Hemin-Polymer System Against Escherichia coli and Staphylococcus aureus

Антибиотики и Химиотерапия
Background. Wound infections of bacterial etiology are a socially significant problem. The lack of rational antibiotic therapy can lead to an increase in the emergence of resistant strains of microorganisms.

Hemin and iron increase synthesis and trigger export of xanthine oxidoreductase from hepatocytes to the circulation

Redox Biology, 2023
We recently reported a previously unknown salutary role for xanthine oxidoreductase (XOR) in intravascular heme overload whereby hepatocellular export of XOR to the circulation was identified as a seminal step in affording protection.

Dual‐Function Electrocatalysis: Simultaneous Wastewater Remediation and Hydrogen Evolution—A Comprehensive Review

Carbon Energy, EarlyView.
Replacing the oxygen evolution reaction with the electro‐oxidation of pollutants and waste streams offers an energy‐efficient route for simultaneous hydrogen production and pollutant remediation. This review summarizes the reaction mechanisms, catalyst design principles, and emerging paired‐electrolysis strategies that govern activity, selectivity ...
