APPLICATION OF NADH OXIDASEIN FIBRE OPTIC BIOSENSORS [PDF]

A newfully reversible fibre-optic detection system based on the detection of NADH-fluorescence is presented. NADH oxidase (EC: 1.6.99.3) was used to regenerate NADH thatis needed for the oxidizing reaction of alcohols and aldehyds by different ...

Deciphering Electrochemical Generation, Transport, and Reactivity of Hydrogen Species in the Electrochemical Palladium Membrane Reactor

Advanced Science, EarlyView.
This study elucidates hydrogen transport and reaction mechanisms in ePMR using 1‐hexyne hydrogenation as a model reaction. Hydrogen transport operates via dual pathways involving hydrogen atom permeation and H2‐mediated re‐dissociation on secondary metal layers.

Soft Interactions, Rather Than Crowder Size, Determine Deviations From Arrhenius‐Like Kinetics of Phosphofructokinase‐1

Angewandte Chemie, EarlyView.
Our study investigates macromolecular crowding effects in the Arrhenius‐like and non‐Arrhenius temperature regimes of the human platelet isoform of phosphofructokinase‐1 (PFKP). The results reveal how PFKP maintains temperature robustness of catalytic activity in differently crowded environments.

Polyphosphate Copper Nanospheres Drive Mitochondrial Metabolic Reprogramming via Calcium Phase Separation for Self‐Sensitizing Cuproptosis

Advanced Science, EarlyView.
This study developed polyphosphate (polyP)‐based nanostructures that enable calcium‐mediated metabolic reprogramming via liquid–liquid phase separation (LLPS). Released polyP undergoes LLPS with Ca2+, suppressing glycolytic flux and enhancing mitochondrial metabolism effectively.

Macrophage GLUD1 is Essential for Redox Balance and Immune Homeostasis in Cardiac Injury

Advanced Science, EarlyView.
Excessive free radical production and dysregulated immune responses are key contributors to myocardial ischemia‐reperfusion (IR) injury. Macrophage GLUD1 activity safeguards against HIF‐1α accumulation and maladaptive responses to IR‐induced ROS production.

Targeting Mitochondrial Redox Signaling Promotes Neuroregeneration and Functional Recovery in a Multiple Sclerosis Model

Advanced Science, EarlyView.
Modulation of mitochondrial redox signaling by furapyrrodole activates CYB5R3 and suppresses Notch signaling, unlocking the regenerative potential of endogenous neural progenitor cells. This approach promotes neurogenesis, oligodendrogenesis, and remyelination, thereby improving neuronal function in a mouse model of multiple sclerosis and identifying ...

Nicotinamide adenine dinucleotide supplementation fails to enhance anesthetic recovery in rodents

Scientific Reports
Nicotinamide Adenine Dinucleotide (NAD+) is implicated in bioenergetics, DNA repair, and senescence. Depletion of NAD+ is associated with aging and neurodegenerative disease, prompting a growing interest in NAD+ supplementation.

PHGDH‐Mediated Serine Metabolism in Nucleus Pulposus Cells Is a Potential Therapeutic Target for Intervertebral Disc Degeneration

Advanced Science, EarlyView.
When nucleus pulposus cells senesce, PHGDH decreases, reducing serine synthesis and glutathione, impairing antioxidant capacity. The intermediate α‐KG also drops, lowering JMJD3 demethylase activity, increasing H3K27me3 at the Rap1b promoter, and reducing Rap1b expression, whose down‐regulation in turn activates mTORC1 and suppresses autophagy ...

pH‐Driven Two‐Stage Conformational Switching Activates an Acid‐Responsive Chaperone

Angewandte Chemie, EarlyView.
AchC is an ATP‐independent, pH‐responsive chaperone. AchC functions as a molecular switch, sensing pH changes and undergoing a two‐stage conformational transition: C‐terminal extension (colored in yellow) loosening at mild pH 4.0–5.5 and monomerization at strong acidic pH 3.0.
