Phenolic Compounds as Potential Antioxidant [PDF]
Jundishapur Journal of Natural Pharmaceutical Products, 2013 An antioxidant may be roughly defined as a substance that when present at low concentrations, lower than the oxidizable compound to be protected, significantly delays or inhibits its oxidation. There are two basic categories of antioxidants, natural and synthetic, the second ones have been found to cause long-term toxicological effects, including ...

The Non-Aqueous Titration of Phenolic Compounds [PDF]
Journal of Pharmacy and Pharmacology, 1957 Abstract The published methods for the titration of very weak acids are reviewed and the choice of a suitable solvent, electrode system and titrant discussed. Ethylenediamine as a solvent is rejected for routine purposes because it is toxic and unpleasant in use. Dimethylformamide is a suitable solvent for phenolic substances and gives a

In silico and in vitro exploration of a tyrosinase for biocatalytic production of catechols
FEBS Open Bio, EarlyView.Tyrosinase from Ralstonia pseudosolanacearum is a promising biocatalyst for producing valuable catechols from monophenol substrates. This tyrosinase is uniquely suited to this due to its high monophenolase : diphenolase ratio. We combined in silico docking and in vivo kinetic characterisation of this tyrosinase with 11 industrially relevant monophenols,

β‐Catenin/c‐Myc Axis Modulates Autophagy Response to Different Ammonia Concentrations
Advanced Biology, Volume 9, Issue 3, March 2025.Ammonia, detoxified by the liver into urea and glutamine, impacts autophagy differently at varying levels. Low ammonia activates autophagy via c‐Myc and β‐catenin, while high levels suppress it. Using Huh7 cells and Spf‐ash mice, c‐Myc's role in cytoprotective autophagy is revealed, offering insights into hyperammonemia and potential therapeutic ...

Development of phenolic concrete mixes and structural behaviour of phenolic concrete components [PDF]
, 1991 This work relates to the development of a method of preparing a filled phenolic resin, for use particularly, but not exclusively, in building materials. The method includes mixing filler and micro-filler, a catalyst, resin and a hetrocyclic alcohol (i.e.

Advanced Engineering Materials, EarlyView.Identified through the use of statistical design of experiments and metallographic investigation, this study exposes the stochastic origins of intergranular cracks in blown powder laser beam directed energy deposition additive manufacturing of pure molybdenum. It further demonstrates a successful crack mitigation approach with direct correlation to the
