Antioxidant Promotion of Tyrosine Nitration in the Presence of Copper(II)

Copper(II) is known to catalyze the generation of reactive nitrogen species in the presence of hydrogen peroxide, nitrite or nitric oxide, leading to tyrosine nitration, a biomarker for free radical species associated diseases. Here, we find that biologica ...

Reactive oxygen species production and signalling as a component of salinity tolerance mechanism in cereals

Amandine Massart

Reactive Oxygen Species (ROS) are highly reactive and toxic by-products of the aerobic metabolism, which are overproduced during period of stress. They disturb the cell machinery and induce oxidative damages on important biological macromolecules. Salinity ...

Corona protein composition and cytotoxicity evaluation of ultra-small zeolites synthesized from template free precursor suspensions

Cécile Hébert, Emad Oveisi

The toxicity of two types of ultra-small zeolites (8–18 nm) with LTL- and EMT-type structures is reported. Both the LTL- and EMT-type zeolites belong to the same group of molecular sieves; they have large pores (7.1–7.5 Å) and low silica content (Si/Al = 1 ...

RF-plasma pretreatment of surfaces leading to TiO2 coatings with improved optical absorption and OH-radical production

César Pulgarin, Juan Kiwi, Christophe Roussel, Sami Rtimi, Oualid Baghriche

Evidence is presented for the RF pretreatment of polyester enhances the TiO2 coating generation of oxidative species/radicals under a low level actinic light irradiation. After 30 min RF-plasma pretreatment of the polyester samples, the fastest bacterial i ...

Oxidative and nitrative alpha-synuclein modifications and proteostatic stress: implications for disease mechanisms and interventions in synucleinopathies

Hilal Lashuel

Alpha-synuclein (ASYN) is a major constituent of the typical protein aggregates observed in several neurodegenerative diseases that are collectively referred to as synucleinopathies. A causal involvement of ASYN in the initiation and progression of neurolo ...

Deletion of Sirt3 does not affect atherosclerosis but accelerates weight gain and impairs rapid metabolic adaptation in LDL receptor knockout mice: implications for cardiovascular risk factor development

Johan Auwerx, Julien Weber, Yuan Liu, Chad Brokopp

Sirt3 is a mitochondrial NAD(+)-dependent deacetylase that governs mitochondrial metabolism and reactive oxygen species homeostasis. Sirt3 deficiency has been reported to accelerate the development of the metabolic syndrome. However, the role of Sirt3 in a ...

Predicting Fish Acute Toxicity Using a Fish Gill Cell Line-Based Toxicity Assay

Kristin Schirmer

The OECD test guideline 203 for determination of fish acute toxicity requires substantial numbers of fish and uses death as an apical end point. One potential alternative are fish cell lines; however, several studies indicated that these appear up to sever ...

Treatment with CB2 Agonist JWH-133 Reduces Histological Features Associated with Erectile Dysfunction in Hypercholesterolemic Mice

Nikolaos Stergiopoulos, Rafaela Fernandes Da Silva, Younouss Faye

Hypercholesterolemia is one of the most important risk factors for erectile dysfunction, mostly due to the impairment of oxidative stress and endothelial function in the penis. The cannabinoid system might regulate peripheral mechanisms of sexual function; ...

The NAD(+)/Sirtuin Pathway Modulates Longevity through Activation of Mitochondrial UPR and FOXO Signaling

Johan Auwerx, Kristina Schoonjans, Carlos Canto Alvarez, Laurent Mouchiroud, Richardus Houtkooper, Dongryeol Ryu, Elena Katsyuba, Norman Lionel Moullan, Adrienne Joëlle Laurence Mottis

NAD(+) is an important cofactor regulating metabolic homeostasis and a rate-limiting substrate for sirtuin deacylases. We show that NAD(+) levels are reduced in aged mice and Caenorhabditis elegans and that decreasing NAD(+) levels results in a further red ...

Subsecond and in Situ Chemical Speciation of Pt/Al2O3 during Oxidation Reduction Cycles Monitored by High-Energy Resolution Off-Resonant X-ray Spectroscopy

Davide Ferri, Oliver Kröcher, Olga Safonova

We report an in situ time-resolved high-energy resolution off-resonant spectroscopy study with subsecond resolution providing insight into the oxidation and reduction steps of a Pt catalyst during CO oxidation. The study shows that the slow oxidation step ...
