Evaluation of the Effects of Nicotinic Acid and Folic Acid on Morphology, Membrane Integrity and Quality of Sperm Chromatin Concentration in Normozoospermic Men during Cryopreservation.

open access: yesمجله علمی دانشگاه علوم پزشکی کردستان, 2022
Background and Aim: Sperm cryopreservation is an important assisted reproductive technique. However, due to increased production of reactive oxygen species and oxidative stress, it can impair sperm function and reduce quality of fertility.

Surface Interactions during the Removal of Emerging Contaminants by Hydrochar-Based Adsorbents

open access: yesMolecules, 2020
The aim of this work was to test activated carbons derived from hydrochars produced from sunflower stem, olive stone and walnut shells, as adsorbents for emerging contaminants in aqueous solution, namely fluoxetine and nicotinic acid.

Synthesis and characterization of ZnO/β-cyclodextrin/nicotinic acid nanocomposite and its biological and environmental application

open access: yesGreen Processing and Synthesis, 2023
In the present work, the disk-shaped zinc oxide (ZnO) nanoparticles were synthesized and functionalized with β-cyclodextrin (β-CD) and nicotinic acid (vitamin B3) using the wet co-precipitation method.

Influence of nicotinic acid on metabolism of cholesterol and triglycerides in man1

open access: yesJournal of Lipid Research, 1981
The mechanisms for the hypolipidemic action of nicotinic acid were examined in 12 patients with hyperlipidemia. Most patients were studied in the hospital on a metabolic ward.

Sudden anaerobization in Amphibacillus xylanus increases intracellular labile ferrous iron and inhibits cell growth

open access: yesFEBS Open Bio, EarlyView.
Abruptly changing from aerobic to anaerobic conditions (sudden anaerobization) induced growth inhibition and a significant increase in intracellular labile ferrous iron in the aerotolerant anaerobe Amphibacillus xylanus. We found that free flavins mediate efficient electron transfer from NADH to ferric iron under anaerobic conditions, suggesting that ...

The crystal structure of the Borrelia burgdorferi nicotinamidase BBE22 resolves a long‐standing annotation error

open access: yesFEBS Open Bio, EarlyView.
The crystal structure of Borrelia burgdorferi nicotinamidase (PncA/BBE22) reveals the correct full‐length protein initiated from a non‐canonical AUU start codon. The structure validates previous biochemical findings and resolves a long‐standing annotation error, demonstrating that the truncated database sequence is structurally incompatible with the ...
