Download and read online ebook Peroxiporins write by Iria Medraño-Fernandez. This book was released on 2023-10-11. Peroxiporins available in PDF, EPUB and Kindle. To produce energy, aerobic organisms transform oxygen molecules into water. This reductive mechanism yields toxic radical intermediates, collectively known as reactive oxygen species (ROS). Paradoxically, these physiological processes entail the production of potentially damaging species. Evolution has turned this apparent disadvantage into an opportunity for transmitting information. As a result, redox signaling within the cell is an efficient exquisitely organized process. A key element for its regulation is the physical separation of sources and targets into different cell compartments. Peroxiporins, H2O2 transporting proteins spanning biological membranes, distribute the signal from emitters to receptors. Thus, these channels are strategically situated in the thin line between life and death, guaranteeing adequate but safe signaling. Key Features: - Provides a brief history of the discovery and characterization of peroxiporins - Reviews key findings on hydrogen peroxide transport across biological membranes - Discusses the cartography of redox signaling in crowded cells - Includes lavish illustrations and comprehensive images to facilitate teaching - Highlights recent findings, outstanding controversies and open questions

Download and read online ebook Hydrogen Peroxide Metabolism in Health and Disease write by Margreet C M Vissers. This book was released on 2017-10-19. Hydrogen Peroxide Metabolism in Health and Disease available in PDF, EPUB and Kindle. Much of the biology of oxidative stress and oxidative signalling centres on the generation and handling of hydrogen peroxide. The overall aim for this book would be to provide an insightful and useful forum to assist with the understanding of the relevance of hydrogen peroxide generation and how this is managed in human biology. The target audience would be those who currently have an interest in the generation of ROS, but who do not have expertise in chemistry, as well as those experts in the chemistry of oxidative stress, but without detailed understanding of the biologically relevant setting. We would aim to bridge the gap in understanding between chemistry and biology.

Download and read online ebook Oxidative Stress write by Helmut Sies. This book was released on 2019-11-07. Oxidative Stress available in PDF, EPUB and Kindle. Oxidative Stress: Eustress and Distress presents current knowledge on oxidative stress within the framework of redox biology and translational medicine. It describes eustress and distress in molecular terms and with novel imaging and chemogenetic approaches in four sections: A conceptual framework for studying oxidative stress. Processes and oxidative stress responses. Signaling in major enzyme systems (oxidative eustress), and damaging modification of biomolecules (oxidative distress). The exposome addresses lifelong exposure and impact on health, nutrient sensing, exercise and environmental pollution. Health and disease processes, including ischemia-reperfusion injury, developmental and psychological disorders, hepatic encephalopathy, skeletal muscle disorders, pulmonary disease, gut disease, organ fibrosis, and cancer. Oxidative Stress: Eustress and Distress is an informative resource useful for active researchers and students in biochemistry, molecular biology, medicinal chemistry, pharmaceutical science, nutrition, exercise physiology, analytical chemistry, cell biology, pharmacology, clinical medicine, and environmental science. Characterizes oxidative stress within the framework of redox biology, redox signaling, and medicine. Empowers researchers and students to quantify specific reactants noninvasively, identify redox biomarkers, and advance translational studies. Features contributions from international leaders in oxidative stress and redox biology research.

Download and read online ebook XIIIth International Symposium on Spermatology write by Lars Björndahl. This book was released on 2021-07-22. XIIIth International Symposium on Spermatology available in PDF, EPUB and Kindle. These proceedings of the 2018 XIII International Symposium on Spermatology focus on comparative biology, and encourages discussion and the exchange of ideas. The aim of this Symposium was to provide a unique opportunity and bring together scientists from a wide spectrum of research fields – human, domestic animals and other mammals, vertebrates, insects, and plants. The underlying focus is on the function of the spermatozoon – a common feature for sexual reproduction, but extremely varied. By exploring the variability, a better understanding of male reproductive functions can develop. These proceedings address the mechanisms of physiology and pathophysiology, rather than diagnosis and treatment. The symposium featured keynote lectures by invited speakers, followed by presentations on specific aspects of the general topic of the session. Experimental studies are given priority over clinical studies of patient populations. The proceedings comprise both keynote speakers' texts and selected free communications. Posters were considered for publication in the proceedings, and the volume includes exhibited materials on the work of prominent spermatologists, highlighting their important past achievements in the field.

Download and read online ebook The Changing Faces of Glutathione, a Cellular Protagonist write by Alfonso Pompella. This book was released on 2015-07-17. The Changing Faces of Glutathione, a Cellular Protagonist available in PDF, EPUB and Kindle. Glutathione (GSH) has been described for a long time just as a defensive reagent against the action of toxic xenobiotics (drugs, pollutants, carcinogens), both directly and as a cofactor for GSH transferases. As a prototype antioxidant, it has been involved in cell protection from the noxious effect of excess oxidant stress, both directly and as a cofactor of glutathione peroxidases. In addition, it has long been known that GSH is capable of forming disulfide bonds with cysteine residues of proteins, and the relevance of this mechanism ("S-glutathionylation") in regulation of protein function has been well documented in a number of research fields. Rather paradoxically, it has also been highlighted that GSH—and notably its catabolites, as originated by metabolism by gamma-glutamyltransferase—can promote oxidative processes, by participating in metal ion-mediated reactions eventually leading to formation of reactive oxygen species and free radicals. Also, a fundamental role of GSH has been recognized in the storage and transport of nitric oxide (NO), in the form of S-nitrosoglutathione (GSNO). The significance of GSH as a major factor in regulation of cell life, proliferation, and death, can be regarded as the integrated result of all these roles, as well as of more which are emerging in diverse fields of biology and pathophysiology. Against this background, modulation of GSH levels and GSH-related enzyme activities represents a fertile field for experimental pharmacology in numerous and diverse perspectives of animal, plant and microbiologic research. This research topic includes 14 articles, i.e. 4 Opinion Articles, 6 Reviews, and 4 Original Research Articles. The contributions by several distinguished research groups, each from his own standpoint of competence and expertise, provide a comprehensive and updated view over the diverse roles, the changing faces of GSH and GSH-related enzymes in cell’s health, disease and death.
