Lanthanide vanadate-based trimodal probes for near-infrared luminescent bioimaging, high-field magnetic resonance imaging, and X-ray computed tomography

Dic 6, 2023 | Artículos del Mes

We have developed a trimodal bioimaging probe for near-infrared luminescent imaging, high-field magnetic resonance imaging, and X-ray computed tomography using Dy3+ as the paramagnetic component and Nd3+ as the luminescent cation, both of them incorporated in a...

The contribution of glutathione peroxidases to chloroplast redox homeostasis in Arabidopsis

Nov 6, 2023 | Artículos del Mes, Artículos del Mes, Artículos del Mes, Artículos del Mes, Artículos del Mes

Oxidizing signals mediated by the thiol-dependent peroxidase activity of 2-Cys peroxiredoxins (PRXs) plays an essential role in fine-tuning chloroplast redox balance in response to changes in light intensity, a function that depends on NADPH-dependent thioredoxin...

Herein a versatile and scalable method to prepare periodically corrugated nanophosphor surface patterns displaying strongly polarized and directional visible light emission is demonstrated. A combination of inkjet printing and soft lithography techniques is employed...

Dynamic Kinetic Resolution of 2-(Quinolin-8-yl)benzaldehydes: Atroposelective Iridium-Catalyzed Transfer Hydrogenative Allylation

Sep 6, 2023 | Sin categoría

An atroposelective Ir-catalyzed dynamic kinetic resolution (DKR) of 2-(quinolin-8-yl)benzaldehydes/1-naphthaldehydes by transfer hydrogenative coupling of allyl acetate is disclosed. The allylation reaction takes place with simultaneous installation of central and...

Cytochrome c lysine acetylation regulates cellular respiration and cell death in ischemic skeletal muscle

Ago 6, 2023 | Sin categoría

Skeletal muscle is more resilient to ischemia-reperfusion injury than other organs. Tissue specific post-translational modifications of cytochrome c (Cytc) are involved in ischemia-reperfusion injury by regulating mitochondrial respiration and apoptosis. Here, we...

Stress response requires efficient glycogen and central carbon metabolism connection by phosphoglucomutases in cyanobacteria

Jul 21, 2023 | Sin categoría

Glycogen and starch are the main storage polysaccharides, acting as a source of carbon and energy when necessary. Interconversion of glucose-1-phosphate and glucose-6-phosphate by phosphoglucomutases connects the metabolism of these polysaccharides with central carbon...
