Pathway analysis of NAD+ metabolism [PDF]

open access: yesBiochemical Journal, 2011
NAD+ is well known as a crucial cofactor in the redox balance of metabolism. Moreover, NAD+ is degraded in ADP-ribosyl transfer reactions, which are important components of multitudinous signalling reactions. These include reactions linked to DNA repair and aging.

Structural dynamic modification of vibrating systems [PDF]

open access: yesApplied and Computational Mechanics, 2007
Vibration and acoustic requirements are becoming increasingly important in the design of mechanical structures. The need to vary the structural behaviour to solve noise and vibration problems occurs at design or prototype stage, giving rise to the so ...

Effect of Dietary Ketosis and Nicotinamide Riboside on Hippocampal Krebs Cycle Intermediates and Mitochondrial Energetics in a DNA Repair‐Deficient 3xTg/POLβ+/− Alzheimer Disease Mouse Model

open access: yesJournal of Neurochemistry, Volume 169, Issue 1, January 2025.
Alzheimer disease causes neurodegeneration of the hippocampus. It impedes brain glucose metabolism and impairs mitochondrial energy along electron transport chain (ETC). Will a ketone‐based diet with nicotinamide riboside restore hippocampal energy in an Alzheimer mouse model?

NAD+ Homeostasis and NAD+-Consuming Enzymes: Implications for Vascular Health

open access: yesAntioxidants, 2023
Nicotinamide adenine dinucleotide (NAD+) is a ubiquitous metabolite that takes part in many key redox reactions. NAD+ biosynthesis and NAD+-consuming enzymes have been attracting markedly increasing interest since they have been demonstrated to be involved in several crucial biological pathways, impacting genes transcription, cellular signaling, and ...

Dual treatment with kynurenine pathway inhibitors and NAD+ precursors synergistically extends life span in Drosophila

open access: yesAging Cell, Volume 23, Issue 4, April 2024.
Our study explores the impact of kynurenine pathway (KP) modulation and NAD+ supplementation on aging Drosophila. We found that KP inhibition combined with NAD+ precursors significantly enhances physical performance and extends life span. These findings suggest that targeted interventions in KP and NAD+ metabolism can synergistically improve health ...

Can Aspartate Aminotransferase in the Cerebrospinal Fluid Be a Reliable Predictive Parameter?

open access: yesBrain Sciences, 2020
Brain ischemia after central nervous system (CNS) bleeding significantly influences the final outcome of patients. Catalytic activities of aspartate aminotransferase (AST) in the cerebrospinal fluid (CSF) to detect brain ischemia were determined in this ...

Metabolic control of mitophagy

open access: yesEuropean Journal of Clinical Investigation, Volume 54, Issue 4, April 2024.
Abstract Mitochondrial dysfunction is a major hallmark of ageing and related chronic disorders. Controlled removal of damaged mitochondria by the autophagic machinery, a process known as mitophagy, is vital for mitochondrial homeostasis and cell survival.
