Cooperation between subcellular NAD pools in the maintenance of NAD-dependent processes [PDF]

open access: yes, 2018
Nicotinamide adenine dinucleotide (NAD) is needed as a cofactor in several processes throughout the cell, and its availability is decisive for the activity of many NAD-dependent enzymes.

AMERICAN MULTI-DWELLING ARCHITECTURE OF THE SECOND HALF OF THE 19TH CENTURY AND FIRST HALF OF THE 20TH CENTURY [PDF]

open access: yesAR: Arhitektura, Raziskave, 2013
At the end of the 19th and beginning of the 20th century, the evolution of American multiple-dwelling architecture was marked by the passage from the standard construction of single-family standalone homes and row houses to a new housing typology which ...

Grabbing the genome by the NADs [PDF]

open access: yesChromosoma, 2015
The regions of the genome that interact frequently with the nucleolus have been termed nucleolar-associated domains (NADs). Deep sequencing and DNA-fluorescence in situ hybridization (FISH) experiments have revealed that these domains are enriched for repetitive elements, regions of the inactive X chromosome (Xi), and several RNA polymerase III ...

Intestinal Fut2 deficiency exacerbated alcohol‐related liver disease by disrupting nicotinamide metabolism

open access: yesClinical and Translational Medicine, Volume 15, Issue 8, August 2025.
Loss of intestinal epithelial fucosylation exacerbates alcohol‐related liver injuries. Intestinal epithelial deletion of Fut2 disrupts nicotinamide (NAM) metabolism due to the decline in bacterial nicotinamidase (PncA). Supplemented with pncA overexpressed E.coli to restore gut PncA levels can improve liver damage in alcohol‐induced intestinal ...

Maternal Circulatory NAD Precursor Levels and the Yolk Sac Determine NAD Deficiency‐Driven Congenital Malformation Risk

open access: yesThe FASEB Journal, Volume 39, Issue 14, 31 July 2025.
Maternal circulatory L‐tryptophan (TRP) and nicotinamide (NAM) levels are proportional to dietary TRP intake. Yolk sacs, but not embryos, perform NAD de novo synthesis. This study explores the exchange of NAD precursors between mother and conceptus, and NAD generation in conceptal tissues via the NAD de novo synthesis (blue) or salvage (red) pathways ...

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 ...

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 ...

Effects of Aging on Glucose and Lipid Metabolism in Mice

open access: yesAging Cell, Volume 24, Issue 4, April 2025.
Lien et al. report a characterization of metabolism with aging across three different strains of mice. They find that glucose metabolism is robust during healthy aging; however, aging tissues exhibit evidence of upregulated fatty acid and sphingolipid metabolism reactions that regenerate NAD+ from NADH.
