The evaluation of possibilities of sustainable tourism and recreation in the Mrtva Tisa area near Čurug7 [PDF]

open access: yesGlasnik Srpskog Geografskog Društva, 2008
The preserved parts of the nature or areas that are inteded to be protected and well-planned in terms of harmonizing the nature and tourist activities and recreation could become potential eco-tourist attractions.

Nicotinamide adenine dinucleotide (NAD+). Formal potential of the NAD+/NAD· couple and NAD· dimerization rate [PDF]

open access: yesBiochimica et Biophysica Acta (BBA) - Bioenergetics, 1984
The rate constant, kd, for the dimerization of the free radical (NAD), produced on the initial one-electron reduction of NAD+, was measured by double potential-step chronoamperometry, fast-scan cyclic voltammetry (cathodic-anodic peak current ratio) and slow-scan cyclic voltammetry (peak potential shift) for a medium in which neither NAD+ nor its ...

Sirtuins in the pathogenetic therapy of neurodegenerative diseases [PDF]

open access: yesКлиническая практика
The progressive decline in the physiological functions during aging leads to various diseases that place a heavy burden on patients, their families and the society as a whole.

It takes two to tango: NAD+ and sirtuins in aging/longevity control [PDF]

open access: yes, 2016
The coupling of nicotinamide adenine dinucleotide (NAD+) breakdown and protein deacylation is a unique feature of the family of proteins called ‘sirtuins.’ This intimate connection between NAD+ and sirtuins has an ancient origin and provides a ...

Crystal Structure of Thermotoga maritima α-Glucosidase AglA Defines a New Clan of NAD+-dependent Glycosidases [PDF]

open access: yes, 2003
Glycoside hydrolase family 4 represents an unusual group of glucosidases with a requirement for NAD(+), divalent metal cations, and reducing conditions. The family is also unique in its inclusion of both alpha- and beta-specific enzymes.

CD38, CD157, and RAGE as Molecular Determinants for Social Behavior

open access: yesCells, 2019
Recent studies provide evidence to support that cluster of differentiation 38 (CD38) and CD157 meaningfully act in the brain as neuroregulators. They primarily affect social behaviors. Social behaviors are impaired in Cd38 and Cd157 knockout mice. Single-

Development of the Cerebrospinal Fluid in Early Stage after Hemorrhage in the Central Nervous System

open access: yesLife, 2021
Extravasation of blood in the central nervous system (CNS) represents a very strong damaged associated molecular patterns (DAMP) which is followed by rapid inflammation and can participate in worse outcome of patients.

NAD+-dependent DNA ligases of Mycobacterium tuberculosis and Streptomyces coelicolor [PDF]

open access: yes, 2003
Sequencing of the genomes of Mycobacterium tuberculosis H37Rv and Streptomyces coelicolor A3(2) identified putative genes for an NAD+-dependent DNA ligase. We have cloned both open reading frames and overexpressed the protein products in Escherichia coli.

“NAD-capQ” detection and quantitation of NAD caps [PDF]

open access: yesRNA, 2018
RNA 5′ cap structures comprising the metabolic effector nicotinamide adenine dinucleotide (NAD) have been identified in diverse organisms. Here we report a simple, two-step procedure to detect and quantitate NAD-capped RNA, termed “NAD-capQ.” By use of NAD-capQ we quantitate NAD-capped RNA levels in Escherichia coli, Saccharomyces cerevisiae, and human

Whole blood NAD and NADP concentrations are not depressed in subjects with clinical pellagra [PDF]

open access: yes, 2007
Population surveys for niacin deficiency are normally based on clinical signs or on biochemical measurements of urinary niacin metabolites. Status may also be determined by measurement of whole blood NAD and NADP concentrations. To compare these methods,
