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 ...

MXenes as a Versatile Platform for High‐Energy‐Density Asymmetric Supercapacitors

Carbon Energy, EarlyView.
MXenes with high conductivity and tunable surface chemistry are reviewed as advanced electrodes for asymmetric supercapacitors. MAX‐phase synthesis, surface and interlayer engineering, defect modulation, and composite designs are discussed, highlighting enhanced ion transport, pseudocapacitance, energy density, cycling stability, and sustainable routes

Exogenous ochronosis: case report and literature review Ocronose exógena: relato de caso e revisão de literatura

Anais Brasileiros de Dermatologia, 2012
Exogenous ochronosis is a rare, cosmetically disfiguring condition, resulting from the longterm use of topical hydroquinone in treatment of melasma. It manifests as gray-brown or blue-black macules in hydroquinone-exposed regions.

Modulation of Epigenetic Control by Advanced Molecular Tweezers

Chemistry – A European Journal, EarlyView.
Tailored dimeric molecular tweezers recognize the DNA‐binding part of Histone H4 and interrupt the essential histone‐DNA interaction. ABSTRACT This work addresses the question if supramolecular systems can be tailored to interfere with posttranslational modifications (PTM) and epigenetics.

New sesquiterpene hydroquinones from the Caribbean sponge Aka coralliphagum

Beilstein Journal of Organic Chemistry, 2014
Four new sulfated sesquiterpene hydroquinones siphonodictyals E1–E4 (1–4) and cyclosiphonodictyol A (5) were isolated from a sample of the Caribbean sponge Aka coralliphagum collected off the coast of San Salvador in the Bahamas.

Designing Threefold π‐Surfaces Through Peripheral Halogenation to Shape Multidirectional Molecular Packing

Chemistry – A European Journal, EarlyView.
The complete series of hexahalogenated triptycene‐tribenzoquinones, comprising newly synthesized fluoro‐, bromo‐, and iodo‐substituted derivatives together with the previously reported chloro analogue, enables systematic comparison of their molecular properties and intermolecular interactions in relation to their crystal packing modes.

On-line Electrochemical Tagging of Free Cysteines in Peptides during Nanospray Ionisation Mass Spectrometry: An Overview

CHIMIA, 2004
A recently developed nanospray interface for mass spectrometry (MS) was used to electro-generate benzoquinone from hydroquinone. When spraying biomolecules containing free cysteine residues in the presence of hydroquinone, the thiol cysteine ...
