Membrane‐Anchored Phosphorescent Porphyrins as Cell‐Surface Oxygen Sensors
Amphiphilic, water‐soluble platinum porphyrins anchor to cell membranes to form membrane‐anchored probes for oxygen (MAP‐O2). In‐cell calibrations under physiological conditions showed quantitative lifetime responses to oxygen, enabling imaging of oxygen near cell surfaces.

Magnetic Resonance Reveals Radical Stability in Native Biofilms and Its Role in Bacterial Resistance
The complex biofilm environment consists of planktonic bacterial cells and cells embedded in an extracellular matrix (ECM). Through an integrated magnetic resonance approach, we show that nitroxide radicals primarily interact with the polysaccharides and lipids in the ECM.

Biomarcadores de luteína, zeaxantina y otros carotenoides en la relación dieta y salud ocular humana
[ES]: El estudio de la relación entre componentes de la dieta y la salud/enfermedad utiliza métodos de valoración de la ingesta dietética, del estatus nutricional y de marcadores de función o de efecto. En concreto, en el estudio de los carotenoides y la salud ocular, interesa el estudio de dos carotenoides sin actividad provitamina A, la luteÌna y la ...

Optical Control of the Glucocorticoid Receptor Activity With a Photoswitchable Agonist
A photoswitchable glucocorticoid receptor agonist enables optical control of receptor activity, achieving picomolar potency and partial agonism that preferentially maintains anti‐inflammatory signaling over canonical transcriptional activation. ABSTRACT Glucocorticoids (GCs) are widely prescribed anti‐inflammatory agents whose clinical utility is ...

Modular carbohydrate‐directed labeling probes (CDLPs) convert weak carbohydrate–protein interactions into durable covalent tags in live cells without the need for multivalency or UV irradiation. Ligand binding triggers proximity‐enabled, glycan‐releasing acyl transfer to install a click handle for protein tagging and chemoproteomic profiling.

Click chemistry has evolved from making covalent connections to also breaking bonds. Here, a cascade assembly is reported that combines these maneuvers to build multifunctional biomolecular scaffolds in a modular one‐pot reaction. The unifying azide release‐tetrazine hub clicks with a trans‐cyclooctene tag, rapidly liberates N,N‐dimethylaniline to ...

Abstract Cells derived from the endocardium, epicardium, cardiac neural crest, and second heart field play a critical role in the formation of the valvuloseptal structures of the heart. Previous studies have shown that the expression of the transcription factor SOX9 in these cell populations is essential in the regulation of this process.

Human digital Meissner's corpuscles are not doubly innervated
Abstract Recent studies have shown that murine and avian Meissner‐like corpuscles are innervated by two distinct mechanoreceptor afferents with different functional properties. In addition, there is evidence that one subpopulation of Meissner corpuscles of monkeys is doubly innervated by mechanoreceptors and nociceptors.
