Ilex paraguariensis supplementation may be an effective nutritional approach to modulate oxidative stress during perimenopause
(2017-04-01)
Perimenopause is a period in a woman's life that precedes menopause and is characterized by hormonal changes that result in increased oxidative stress. Since oxidative stress is associated with age-related diseases and ...
Diabetes and Vascular Disease: Basic Concepts of Nitric Oxide Physiology, Endothelial Dysfunction, Oxidative Stress and Therapeutic Possibilities
(BENTHAM SCIENCE PUBL LTD, 2010)
The vascular manifestations associated with diabetes mellitus (DM) result from the dysfunction of several vascular physiology components mainly involving the endothelium, vascular smooth muscle and platelets. It is also ...
Circulating leukocyte heat shock protein 70 (HSP70) and oxidative stress markers in rats after a bout of exhaustive exercise
(Taylor & Francis Ltd, 2006-06-01)
A novel method to measure oxidative stress resulting from exhaustive exercise in rats is presented. In this new procedure we evaluated the erythrocyte antioxidant enzymes, catalase ( CAT) and glutathione reductase (GR), ...
Overexpression of plant uncoupling mitochondrial protein in transgenic tobacco increases tolerance to oxidative stress
(Kluwer Academic/plenum Publ, 2003-06-01)
An Arabidopsis thaliana cDNA clone encoding a plant uncoupling mitochondrial protein (AtPUMP1) was overexpressed in transgenic tobacco plants. Analysis of the AtPUMP1 mRNA content in the transgenic lines, determined by ...
Decreased endothelium-dependent vasoconstriction to noradrenaline in acute-stressed rats is potentiated by previous chronic stress: Nitric oxide involvement
(Elsevier B.V., 1998-01-01)
1. The objective was to determine whether nitric oxide participates in stress adaptive responses. Acute stress (AS) decreased endothelium-dependent vasoconstriction to noradrenaline (NA) in rat aorta [control rat (CR) ...
High-fat and combined high-fat and sucrose diets promote cardiac oxidative stress independent of Nox2 redox regulation and obesity in rats
(2021-01-01)
Background/Aims: Oxidative stress is associated with cardiometabolic alterations, and the involvement of excess glucose and fatty acids has been demonstrated in this process. Thus, the aim of this study was to investigate ...
Tellurite promotes stress granules and nuclear SG-like assembly in response to oxidative stress and DNA damage
(Frontiers Media, 2021)
Tellurium oxyanion, tellurite (TeO3-2), is a highly toxic compound for many organisms. Its presence in the environment has increased over the past years due to industrial manufacturing processes and has been associated ...
The need of a new and more physiological preclinical model for Parkinson's disease
(Birkhauser Verlag AG, 2016)
Direct observation of oxidative stress on the cell wall of Saccharomyces cerevisiae strains with atomic force microscopy
(Kluwer Academic Publ, 1999-11-01)
We imaged pores on the surface of the cell wall of three different industrial strains of Saccharomyces cerevisiae using atomic force microscopy. The pores could be enlarged using 10 mM diamide, an SH residue oxidant that ...
