Generation of oxidative radicals by advanced oxidation processes (AOPs) in wastewater treatment: a mechanistic, environmental and economic review KU Leuven
In light of the rising presence of contaminants of emerging concern in water streams, in recent decades, advanced oxidation processes have received significant research interest, as the generation of oxidative radicals allows for the effective degradation of recalcitrant compounds. This review paper provides insights into the most relevant generation methods of several oxidative species, with a main emphasis on hydroxyl, sulfate, chlorine and ...
Investigating the Oxidation Step in the CuCl2-Catalyzed Aerobic Oxidative Coupling Reaction of N-Aryl Tetrahydroisoquinolines KU Leuven
The oxidative coupling of N-aryl tetrahydroisoquinolines with nucleophiles has inspired the development of novel C−H functionalization reactions as well as mechanistic studies. Here, we investigate the oxidation step that forms iminium ions as key intermediates in the method using CuCl2 as the catalyst and oxygen as the terminal oxidant. A strong electronic effect of substituents in the N-aryl ring was found by synthetic studies and a Hammett ...
Increasing body weight does not affect cellular immunity but alters fat oxidation and oxidative stress in dogs Universiteit Gent
Structural modification of NADPH oxidase activator (Noxa 1) by oxidative stress Universiteit Antwerpen
NADPH oxidases 1 (NOX1) derived reactive oxygen species (ROS) play an important role in the progression of cancer through signaling pathways. Therefore, in this paper, we demonstrate the effect of cold atmospheric plasma (CAP) on the structural changes of Noxa1 SH3 protein, one of the regulatory subunits of NOX1. For this purpose, firstly we purified the Noxa1 SH3 protein and analyzed the structure using X-ray crystallography, and subsequently, ...
Protection of polyunsaturated oils against ruminal biohydrogenation and oxidation during storage using a polyphenol oxidase containing extract from red clover Universiteit Gent
Heavily fluorinated carbohydrates as enzyme substrates : oxidation of tetrafluorinated galactose by galactose oxidase Universiteit Gent
Oxidative Stress Induced by Cadmium and Copper in Brassica rapa Leaves: Indicators of Stress, Oxidative Damage, and Antioxidant Mechanisms Universiteit Hasselt
Brassica rapa is frequently used as a vegetable for human consumption and can accumulate metals that are bioavailable in soils. We studied the oxidative stress induced by 25M cadmium (Cd) and 50M copper (Cu) on Brassica rapa leaves and evaluated the intracellular antioxidative plant response mechanisms and the accumulation of these metals. With this purpose, hydrogen peroxide (H2O2) concentration, lipid peroxidation, and enzymatic and ...
Oxidative damage to hyaluronan–CD44 interactions as an underlying mechanism of action of oxidative stress-inducing cancer therapy Universiteit Antwerpen
Multiple cancer therapies nowadays rely on oxidative stress to damage cancer cells. Here we investigated the biological and molecular effect of oxidative stress on the interaction between CD44 and hyaluronan (HA), as interrupting their binding can hinder cancer progression. Our experiments demonstrated that the oxidation of HA decreased its recognition by CD44, which was further enhanced when both CD44 and HA were oxidized. The reduction of ...
Gene expression of heat shock protein 70 and antioxidant enzymes, oxidative status, and meat oxidative stability of cyclically heat-challenged finishing broilers fed Origanum compactum and Curcuma xanthorrhiza essential oils KU Leuven Universiteit Gent
Heat stress in poultry is a serious problem in many countries and has been associated with oxidative stress. Hence, nutritional interventions with antioxidants might be beneficial. Therefore, the effects of dietary Curcuma xanthorrhiza (CX) and Origanum compactum (OC) essential oils on mRNA levels of heat shock protein 70 and antioxidant enzymes, oxidative status, and meat oxidative stability of heat-challenged broilers were studied. Starting on ...
