Nicotinamide riboside and caffeine partially restore diminished NAD availability but not altered energy metabolism in Alzheimer's disease

Aging Cell, Volume 21, Issue 7, July 2022., 2022
Nicotinamide riboside (NR) and caffeine increase nicotinamide adenine dinucleotide (NAD), transiently modulate bioenergetic functions, and change the expression of NAD‐synthesizing, recycling, or degrading genes in dermal fibroblasts or induced pluripotent stem cell (iPSC)‐derived neural progenitors and astrocytes from late‐onset Alzheimer's disease ...

CD38 Drives Progress of Osteoarthritis by Affecting Cartilage Homeostasis

Orthopaedic Surgery, Volume 14, Issue 5, Page 946-954, May 2022., 2022
CD38 is a membrane‐bound protein. This study primarily implicates CD38 as an important regulator of chondrogenic differentiation. Inhibition of CD38 demonstrated protection against cartilage degeneration, which suggests that CD38 could be a potential therapeutic target for OA.

CD38 inhibitor 78c increases mice lifespan and healthspan in a model of chronological aging

Aging Cell, Volume 21, Issue 4, April 2022., 2022
The NADase CD38 plays a key role in age‐related NAD decline. The CD38 inhibitor 78c increases lifespan and healthspan of naturally aged male mice. The increase in median and maximal lifespan was about 10%. Abstract Nicotinamide adenine dinucleotide (NAD) levels decline during aging, contributing to physical and metabolic dysfunction.

Nicotinamide pathways as the root cause of sepsis – an evolutionary perspective on macrophage energetic shifts

The FEBS Journal, Volume 289, Issue 4, Page 955-964, February 2022., 2022
Increased IDO activity towards de novo nicotinamide synthesis is a hallmark of alternatively activated macrophages. IDO upregulation in alternatively activated macrophages may be an attempt to compensate for insufficient NAD availability. Manipulation of nicotinamide metabolism may shift macrophage metabolism, thereby providing a therapeutic approach ...

Structural and catalytic characterization of Blastochloris viridis and Pseudomonas aeruginosa homospermidine synthases supports the essential role of cation–π interaction

Acta Crystallographica Section D, Volume 77, Issue 10, Page 1317-1335, October 2021., 2021
The homospermidine synthases from P. aeruginosa and B. viridis, as well as their single‐residue variants, are compared based on crystal structures and activity assays. A high structural similarity is demonstrated, suggesting the equivalent involvement of relevant residues in the reaction mechanism and catalytic dependence on cation–π interaction ...

The new insight into extracellular NAD+ degradation‐the contribution of CD38 and CD73 in calcific aortic valve disease

Journal of Cellular and Molecular Medicine, Volume 25, Issue 13, Page 5884-5898, July 2021., 2021
Abstract Nicotinamide adenine dinucleotide (NAD+) is crucial for cell energy metabolism and many signalling processes. Recently, we proved the role of ecto‐enzymes in controlling adenine nucleotide–dependent pathways during calcific aortic valve disease (CAVD).

Characterization of sand boils with grading entropy [PDF]

Zbornik Matice Srpske za Prirodne Nauke, 2012
Grain size and grain distribution by size are dominant factors determining soil behaviour. The shape and position of a grain distribution curve contain implicit information about the propensity of sand boiling or piping at flood conditions. The author
