Download or read book Reactive Oxygen Species ROS in Living Cells written by Filip Cristiana and published by BoD – Books on Demand. This book was released on 2018-05-23 with total page 218 pages. Available in PDF, EPUB and Kindle. Book excerpt: Oxygen represents only 20% of the Earth's atmosphere, yet it is vital for the survival of aerobic organisms. There is a dark part of the use of oxygen that consists in generating reactive species that are potentially harmful to living organisms. Moreover, reactive oxygen species can combine with nitrogen derivatives and generate many other reactive species. Thus, living organisms are continuously assaulted by reactive species from external or internal sources. However, the real danger comes in the case of high concentrations and prolonged exposure to these species. This book presents an image of the mechanisms of action of reactive species and emphasizes their involvement in diseases. Inflammation and cancer are examined to determine when and how reactive species turn the evolution of a benign process to a malignant one. Some answers may come from recent studies indicating that reactive species are responsible for epigenetic changes.

Download or read book Homeostasis written by Fernanda Lasakosvitsch Castanho and published by BoD – Books on Demand. This book was released on 2019-01-30 with total page 174 pages. Available in PDF, EPUB and Kindle. Book excerpt: The human body is composed of several systems and organs, consisting of millions of cells that need relatively stable conditions to function and contribute to the survival of the body as a whole. The maintenance of stable conditions for the cells against the variations of the external environment is an essential function of the body and is called homeostasis. As a consequence of the loss of homeostasis, a disease is manifested. This book aims to provide the reader with an up-to-date view of the self-regulatory mechanisms that are activated to achieve homeostasis, the pathways that are altered during the disease process, and how medicine can intervene to restore balance in critical patients.

Download or read book Reactive Oxygen Species written by and published by BoD – Books on Demand. This book was released on 2024-02-14 with total page 176 pages. Available in PDF, EPUB and Kindle. Book excerpt: Reactive Oxygen Species (ROS) are molecules generated naturally during cellular metabolic processes. They act as signaling agents that oversee specific biochemical pathways, playing a vital role in cell function and survival. However, an imbalance in ROS signaling or excessive ROS production can have harmful effects on the pathophysiology of diseases. ROS are crucial to cell signaling and are involved in various physiological processes. They modulate gene expression, regulate cell cycle progression, and influence immune responses. Although ROS are essential for normal cellular functions, an overabundance of these molecules can lead to oxidative stress, causing DNA damage, lipid peroxidation, and protein oxidation, adversely impacting cell function and leading to various diseases. Therefore, it is critical to regulate ROS levels precisely to maintain cellular homeostasis. Reactive Oxygen Species - Advances and Developments is a comprehensive book that delves into the intricacies of ROS. It provides invaluable insights to researchers in the field, equipping them with the essential tools and knowledge to advance their work in this critical area, leading to the development of novel therapeutic interventions to manage various illnesses.

Download or read book Glutathione System and Oxidative Stress in Health and Disease written by and published by BoD – Books on Demand. This book was released on 2020-08-26 with total page 140 pages. Available in PDF, EPUB and Kindle. Book excerpt: The imbalance between the production of reactive oxygen species (ROS) and antioxidant defenses determines a state known as oxidative stress. Higher levels of pro-oxidants compared to antioxidant defenses may generate oxidative damage, which, in turn, may lead to modifications in cellular proteins, lipids, and DNA, reducing functional capacity and increasing the risk of diseases. Nevertheless, the clearance of harmful reactive chemical species is achieved by the antioxidant defense systems. These protection systems are referred to as the first and second lines of defense and comprise the classic antioxidants, enzymatic and nonenzymatic defenses, including glutathione. This book presents and discusses the advancement of research on health and diseases and their underlying mechanisms, exploring mainly aspects related to the glutathione antioxidant system.
