Increased uptake of α-hydroxy aldehyde-modified low density lipoprotein by macrophage scavenger receptors

open access: yesJournal of Lipid Research, 2000
Reactive aldehydes can be formed during the oxidation of lipids, glucose, and amino acids and during the nonenzymatic glycation of proteins. Low density lipoprotein (LDL) modified with malondialdehyde are taken up by scavenger receptors on macrophages ...

Oxidative stress and the enzyme system of aldehyde catabolism in the muscle mitochondria of immobilized pubertal rats [PDF]

open access: yesThe Ukrainian Biochemical Journal, 2014
The aim of the work is to find out peculiarities in manifestation of oxidative stress and to determine activity of enzymes, responsible for utilization of endogenous aldehydes in the mitochondrial fraction of the skeletal (femoral) muscle in pubertal ...

Tandem Triphosgene-Assisted Metal-Free One-pot Preparation of Nitriles and Amides from Aldehydes and Ketones [PDF]

open access: yes, 2021
Here we report a facile and efficient triphosgene-assisted one-pot conversion of aldehydes/ketones into nitriles/amides. The triphosgene, a kind of phosgene alternative, containing both ester linkage and chloromethyl units, easily reacts with oximes for ...

Formylation of Electron-Rich Aromatic Rings Mediated by Dichloromethyl Methyl Ether and TiCl4: Scope and Limitations

open access: yesMolecules, 2015
Here the aromatic formylation mediated by TiCl4 and dichloromethyl methyl ether previously described by our group has been explored for a wide range of aromatic rings, including phenols, methoxy- and methylbenzenes, as an excellent way to produce ...

The Role of Lipoxidation in the Pathogenesis of Diabetic Retinopathy

open access: yesFrontiers in Endocrinology, 2021
Lipids can undergo modification as a result of interaction with reactive oxygen species (ROS). For example, lipid peroxidation results in the production of a wide variety of highly reactive aldehyde species which can drive a range of disease-relevant ...
