Genetic Polymorphism Associated Prefrontal Glutathione and Its Coupling With Brain Glutamate and Peripheral Redox Status in Early Psychosis

Rolf Gruetter, Lijing Xin, Benoît Schaller, Kim Do, Huanxiang Lu

BACKGROUND: Oxidative stress and glutathione (GSH) metabolism dysregulation has been implicated in the pathophysiology of schizophrenia. GAG-trinucleotide repeat (TNR) polymorphisms in the glutamate-cysteine ligase catalytic gene (GCLC), the rate-limiting ...

Differential coral bleaching—Contrasting the activity and response of enzymatic antioxidants in symbiotic partners under thermal stress

Thomas Krüger

Mass coral bleaching due to thermal stress represents a major threat to the integrity and functioning of coral reefs. Thermal thresholds vary, however, between corals, partly as a result of the specific type of endosymbiotic dinoflagellate (Symbiodinium sp ...

Characterization of the surfaceome of the metal-reducing bacterium Desulfotomaculum reducens

Rizlan Bernier-Latmani, Romain Hamelin, Diego Chiappe, Elena Suvorova Buffat, Elena Cristina Dalla Vecchia, Paul Pao-Yun Shao

Desulfotomaculum reducens strain MI-1 is a Gram-positive, sulfate-reducing bacterium also capable of reducing Fe(III). Metal reduction in Gram-positive bacteria is poorly understood. Here, we investigated Fe(III) reduction with lactate, a non-fermentable s ...

Metal reduction and sporulation in Desulfotomaculum reducens

Elena Cristina Dalla Vecchia

The genera Desulfotomaculum and Clostridium, belonging to the phylum Firmicutes, comprise Gram-positive, low G+C genomic content, anaerobic, spore- forming bacteria. Desulfotomaculum is a metabolically and environmentally versatile genus capable of growing ...

Antioxidant plasticity and thermal sensitivity in four types of Symbiodinium sp

Thomas Krüger

Warmer than average summer sea surface temperature is one of the main drivers for coraltemperature is one of the main drivers for coral bleaching, which describes the loss of endosymbiotic dinoflagellates (genus: Symbiodinium) in reef-building corals. Past ...

Sensing hydrogen peroxide by carbon nanotube/horseradish peroxidase bio-nanocomposite

László Forró, Arnaud Magrez, Endre Horvath, Klara Hernadi

H2O2 is a product of reactions catalysed by several oxidase enzymes and it is essential in environmental and pharmaceutical analyses. The most commonly used enzyme in understanding the biological behaviour of catalysed oxidation of H2O2 is horseradish pero ...

Interfacial Self-Assembly as Catalytic Platform for Multielectron Redox Reactions

Astrid Johana Olaya Avendano

In Nature, many vital biological processes take place across the interface formed between two dielectric media. For instance, photosynthesis and aerobic respiration involve a series of redox reactions occurring across energy-transducing membranes, in charg ...

Anticancer Therapeutics That Target Selenoenzymes: Synthesis, Characterization, in vitro Cytotoxicity, and Thioredoxin Reductase Inhibition of a Series of Gold(I) Complexes Containing Hydrophilic Phosphine Ligands

Paul Joseph Dyson, Angela Casini, Olivier Pierre Zava, elena vergara

Gold(I) complexes bearing water-sol. phosphine ligands, including 1,3,5-triaza-7-phosphaadamantane (PTA), 3,7-diacetyl-1,3,7-triaza-5-phosphabicyclo[3.3.1]nonane (DAPTA), and sodium triphenylphosphine trisulfonate (TPPTS), in combination with thionate liga ...

The role of cytochromes P450 and peroxidases in the detoxification of sulphonated anthraquinones by rhubarb and common sorrel plants cultivated under hydroponic conditions

Jean-Paul Schwitzguebel

Background, aim and scope Sulphonated anthraquinones are precursors of many synthetic dyes and pigments, recalcitrant to biodegradation and thus not eliminated by classical wastewater treatments. In the development of a phytotreatment to remove sulphonated ...

Attenuation of 6-OHDA-induced neurotoxicity in glutathione peroxidase transgenic mice

Patrick Aebischer, Jean-Charles Bensadoun

Normal cellular metabolism produces oxidants which are neutralized within cells by antioxidant enzymes and other antioxidants. An imbalance between oxidants and antioxidants has been postulated to lead to the degeneration of specific populations of neurons ...
