Oxidative Stress: Concept and Some Practical Aspects
Antioxidants, 2020 Oxidative stress is defined as “an imbalance between oxidants and antioxidants in favor of the oxidants, leading to a disruption of redox signaling and control and/or molecular damage”. This Commentary presents basic features of this global concept which

Advanced Synthesis &Catalysis, EarlyView.Enantioenriched α‐/β‐/γ‐thiocarboxylic acids featuring C–S chirality are valuable targets in organic synthesis. This review outlines recent progress in their asymmetric synthesis, including chiral pool approaches, metal‐ /organo‐catalysis, and emerging biocatalytic strategies. Enantiomerically pure α‐/β‐/γ‐thiocarboxylic acids bearing a stereocentre at

Distribution of enzymes cleaving pyridine nucleotides in animal tissues [PDF]
, 1957 A number of enzymes capable of splitting the pyridine nucleotides have been found in animal tissues. A portion of the DPNase (1) that hydrolyzes the nicotinamide ribose bond of DPN and TPN was reported in the microsomes of rat liver (1).

Advanced Science, EarlyView.Treatment of MPTP‐incubated cells with NAD+‐boosters increase the UPRmt/mitophagy‐related mitochondria quality control (MQC). Disturbed plasma UPRmt‐mitophagy‐mediated MQC profiles in PD patient samples. NMN inhibits motor deficit and forestalls neuropathology phenotypes of PD mice, which is required the atf4‐medicated UPRmt pathway.

Quantitive determination of flavin nucleotide using the bacterial bioluminescent reaction [PDF]
, 1969 Photometric method based on the use of bacterial luminiscent reaction quantitatively detects the presence of flavin compounds in all forms of life. Aqueous cellular dispersion of a biological sample with an aqueous perchloric acid ruptures the cells and ...

FK 506 ameliorates the hepatic injury associated with ischemia and reperfusion in rats [PDF]
, 1991 The effect of FK 506 on regeneration of the liver was studied in rats after a two‐thirds partial hepatectomy after 60 min of ischemia of the unresected liver. The animals were divided into three distinct groups of 10 rats each.

Cleavage of Coenzyme B12 by Methylmalonyl Coenzyme A Mutase
Journal of Biological Chemistry, 1973 Abstract Methylmalonyl-CoA mutase-dependent cleavage of coenzyme B12 took place in the presence of succinyl-CoA, one of the substrates of the enzyme, and in the presence of malonyl-CoA, a competitive inhibitor (Ki 0.12 mm). Other competitive inhibitors of the reaction, including acetyl-CoA, propionyl-CoA, glutaryl-CoA, and CoA itself, did not replace ...
