Download or read book Studies on Experimental Toxicology and Pharmacology written by Stephen M. Roberts and published by Humana Press. This book was released on 2015-09-30 with total page 496 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on data describing the roles of free radicals and related reactive species, and antioxidants, in the causes and treatments of diseases, examining both clinical and pre-clinical trials, as well as basic research. The book is divided into sub-sections with chapters on toxicological mechanisms, agents that produce toxicity, and special topics including areas such as antioxidant supplements, oxygen toxicity, toxicogenomics, and marine biology. Studies on Experimental Toxicology and Pharmacology promotes the concept of using biomarkers of free radical- and reactive species-induced injury as adjuncts to classical laboratory testing and the ability of antioxidants to provide cellular protection. There is increasing evidence that free radicals and other reactive species are causative, or at least supporting factors, that impact organisms and cause numerous tissue disorders. With contributions from international experts in the field, this volume is a valuable resource for researchers and postgraduate students in toxicology and related fields, as well as clinicians and clinical researchers.

Download or read book The Electronic Transitions of Molecular Oxygen written by Mikkel Bregnhøj and published by Springer. This book was released on 2018-12-15 with total page 162 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents the fundamentals and the state of the art of the photophysics of molecular oxygen. The author examines optical transitions between the lowest-lying electronic states in molecular oxygen and how these transitions respond to perturbation, either from an organic molecule or from the plasmon field of a metal nanoparticle. We live on a planet filled with light and oxygen. The interaction between these two components forms the basis of excited state chemistry spanning the fields of synthetic organic chemistry, materials chemistry, molecular biology, and photodynamic treatment of cancer. Still, the fundamental ways in which oxygen is affected by light is an active subject of research and is continually being developed and rationalized. In this book, readers will learn that singlet oxygen, the excited state of oxygen that exhibits unique chemical reactivity, can be selectively made via direct optical excitation of oxygen in a sensitizer-free system. Readers will also discover that this approach can perturb living cells differently depending on the singlet oxygen “dose”.

This book was released on 2014-11-22 with total page 672 pages. Available in PDF, EPUB and Kindle. Book excerpt: Harnessing the sun’s energy via photosynthesis is at the core of sustainable production of food, fuel, and materials by plants, algae, and cyanobacteria. Photosynthesis depends on photoprotection against intense sunlight, starting with the safe removal of excess excitation energy from the light-harvesting system, which can be quickly and non-destructively assessed via non-photochemical quenching of chlorophyll fluorescence (NPQ). By placing NPQ into the context of whole-organism function, this book aims to contribute towards identification of plant and algal lines with superior stress resistance and productivity. By addressing agreements and open questions concerning photoprotection’s molecular mechanisms, this book contributes towards development of artificial photosynthetic systems. A comprehensive picture –from single molecules to organisms in ecosystems, and from leading expert’s views to practical information for non-specialists on NPQ measurement and terminology – is presented.

Available in PDF, EPUB and Kindle. Book excerpt: Janus, the ancient Roman god depicted with two faces is an appropriate metaphor for light therapy. In the right photodynamic therapy conditions, light is able to kill nearly anything that is living such as cancers, microorganisms, parasites, and more. On the opposite face, light of the correct wavelength and proper dose (photobiomodulation) can heal, regenerate, protect, revitalize and restore any kind of dead, damaged, stressed, dying, degenerating cells, tissue, or organ system. This book discusses both sides of Janus' face in regards to light therapy.

Book excerpt: "Sun Protection in Man" looks at the beneficial and harmful effects of solar radiation. The physiological consequences of sun exposure have been systematically studied starting at the end of the nineteenth century and we now have accumulated knowledge about how Caucasian and Asian skins reacts to solar radiation. The chemical effects of solar ultraviolet radiation have been analyzed with particular emphasis during the second half of the twentieth century. Research on micro-organisms has allowed us to understand the mechanisms of UV-induced mutagenesis and photosensitization. Studies with laboratory rodents have opened the path to the understanding of UV-induced immune-depression, carcinogenesis, photo-damage and photo-aging. The results of these studies have enabled other scientists to investigate the same phenomena in human organs such as the skin and the eye. UV radiation damages hair, as well. The present knowledge in these fields is summarized in some of the chapters of this monograph.Mass phenomenon in Europe with the generalization of summer vacations which were a consequence of social reforms introducing the concept of "paid vacations". This created a need for protection and opened a market for sunscreens. This monograph is concerned with sun protection as a whole and is not just "another book on sunscreens". Nonetheless, in these days of general concern, it is important to learn about the efficiency of sunscreens. Several authors discuss how to reduce the number of impinging photons and explain why sunscreens seem to offer less protection than expected. Guidelines are given on how to use sunscreens in everyday life, which are expressed rigorously though clearly, for access to the common reader.Our knowledge on the relationship between sun and humans is at the early stages of development. Industrial and commercial activities are concerned by the development of this knowledge, and rules have been and will be promulgated to guarantee efficacy and safety of sun-products. It is hoped that this monograph will be of interest to the scholar, the layman and the legislator.
