Novel hybrid materials based on alginate-boehmite-riboflavin for photogeneration of reactive oxygen species in aqueous media: Potential environmental implications
(Elsevier, 2020-06)
In this work, hybrid composites based on beads of alginate, boehmite and riboflavin-5′-phosphate dye (ALG-B-RP) were synthesized in order to obtain novel materials capable to generate reactive oxygen species (ROS). The ...
Serum reactive oxygen species and apoptosis markers in septic patients
(Termedia Publishing House Ltd, 2020-12)
Background: Oxidative stress is one of the pathophysiological processes that occur during sepsis. Reactive oxygen species (ROS) production causes lipid peroxidation and protein and DNA damage. ROS and DNA damage triggers ...
Reactive oxygen species-mediated degradation of antidiabetic compounds: Cytotoxic implications of their photodegradation products
(Wiley Blackwell Publishing, Inc, 2018-11)
Reactive oxygen species (ROS) have been described in their double physiological function, helping in the maintenance of health as well as contributing to oxidative stress. Diabetes mellitus is a chronical disease nearly ...
Blue-light dependent reactive oxygen species formation by Arabidopsis cryptochrome may define a novel evolutionarily conserved signaling mechanism
(Wiley Blackwell Publishing, Inc, 2015-06)
Cryptochromes are widespread blue-light absorbing flavoproteins with important signaling roles. In plants they mediate de-etiolation, developmental and stress responses resulting from interaction with downstream signaling ...
Oxidative stress under low oxygen conditions triggers hyperflagellation and motility in the Antarctic bacterium Pseudomonas extremaustralis
(Springer Tokyo, 2019-06)
Reactive oxygen species and nitrogen species (ROS and RNS), produced in a wide range of physiological process even under low oxygen availability, are among the main stressors found in the environment. Strategies developed ...
Reactivity and Morphology of Oxygen-Modified Au Surfaces
(American Chemical Society, 2012-08-07)
Inducing the adsorption of oxygen on gold surfaces transforms the inert metal into a surprisingly reactive material, which acts as a highly selective, low-temperature catalyst. The strong interaction of atomic oxygen with ...
Determination of Reactive Oxygen Species in Salt-Stressed Plant Tissues
(Humana Press, 2012-08)
Reactive oxygen species (ROS) participate in signaling events that regulate ion channel activity and gene expression. However, excess ROS exert adverse effects that stem from their interaction with macromolecules. Thus, ...
Priming Astrocytes With HIV-Induced Reactive Oxygen Species Enhances Their Trypanosoma cruzi Infection
(Frontiers Media S.A., 2020-10)
Introduction: Trypanosoma cruzi is an intracellular protozoa and etiological agent that causes Chagas disease. Its presence among the immunocompromised HIV-infected individuals is relevant worldwide because of its impact ...
New insights into the functional roles of reactive oxygen species during embryo sac development and fertilization in Arabidopsis thaliana
(Taylor & Francis, 2013-10)
Previously considered as toxic by-products of aerobic metabolism, reactive oxygen species (ROS) are emerging as essential signaling molecules in eukaryotes. Recent evidence showed that maintenance of ROS homeostasis during ...
Expression of a plastid-targeted flavodoxin decreases chloroplast reactive oxygen species accumulation and delays senescence in aging tobacco leaves
(Frontiers Research Foundation, 2018-07)
Leaf senescence is a concerted physiological process involving controlled degradation of cellular structures and reallocation of breakdown products to other plant organs. It is accompanied by increased production of reactive ...
