Book Synopsis Singlet Oxygen Detection and Imaging by : Steffen Hackbarth
Download or read book Singlet Oxygen Detection and Imaging written by Steffen Hackbarth and published by Springer Nature. This book was released on 2022-05-31 with total page 85 pages. Available in PDF, EPUB and Kindle. Book excerpt: Singlet Oxygen, the lowest electronically excited state of molecular oxygen, is highly reactive and involved in many chemical and biological processes. It is one major mediator during photosensitization, which has been used by mankind since ancient times, even though the mechanisms behind it were understood only about half a century ago. The combination of high reactivity and very long natural lifetime allows for direct optical detection of singlet oxygen and its interactions using its characteristic phosphorescence at around 1270 nm. Since this emission is very weak, optical detection was technically very challenging for a long time. Therefore, even today, most laboratories only exploit the high reactivity to observe the interaction with sensor molecules, rather than singlet oxygen emission itself. However, in recent years highly sensitive optical detection was developed, the authors being major contributors. This book is dedicated to the detection of singlet oxygen, discussing possibilities, pitfalls and limits of the various methods with a special focus on time-resolved phosphorescence and the kinetics of singlet oxygen generation and decay including involved and related processes, discussing investigated systems with various complexity from solutions over in vitro to in vivo. The long-standing paradigm that singlet oxygen phosphorescence is a benchmark for detection systems rather than an option for process observation is still ubiquitous and this book hopes to contribute in overcoming this still prevailing bias.

Book Synopsis Free Radicals in Exercise and Aging by : Zsolt Radák
Download or read book Free Radicals in Exercise and Aging written by Zsolt Radák and published by Human Kinetics. This book was released on 2000 with total page 286 pages. Available in PDF, EPUB and Kindle. Book excerpt: Explore the emerging field of free radical biology, exercise, and aging with this definitive reference. Free Radicals in Exercise and Agingaddresses the current debate regarding whether free radicals released during exercise accelerate the aging process. It explains how free radicals can serve as important regulators of aerobic processes, and it clarifies the importance of exercise in increasing the efficiency of the antioxidant and oxidative repair systems. Mounting research data indicate that free radicals are involved in a variety of physiological and pathophysiological processes. This book focuses on exercise-induced adaptation. In general, a person's ability to adapt to internal and external changes decreases during the aging process. However, by continually exposing the body to different challenges, regular exercise triggers an adaptation process that keeps the body and mind fit. Free Radicals in Exercise and Agingelucidates the role of free radical species in regulating this process. This text is also one of the first to provide an in-depth review of skeletal muscle oxidative stress and aging. This issue is pivotal because muscle serves such a critical role in mobility and normal life. Free Radicals in Exercise and Aging shares the most current understanding of how reactive oxygen species influence the biology of skeletal muscles. It explores some of the unique characteristics that skeletal muscle displays during aging, both in terms of free radical production and with regard to antioxidant systems. The implications of this research are far-reaching. Mutation of DNA is linked very closely to cancer, and if regular exercise improves the regulation of the antioxidant systems and the oxidative damage repair system, these mechanisms may be a very important tool against this deadly disease. This research-oriented text presents the latest information on the subject. It reviews and critiques current literature and provides critical information for exercise physiologists, sports medicine specialists, sport nutritionists, and gerontologists.
Book Synopsis Reactive Oxygen Species in Plant Signaling by : Luis A. del Río
Download or read book Reactive Oxygen Species in Plant Signaling written by Luis A. del Río and published by Springer Science & Business Media. This book was released on 2009-06-22 with total page 245 pages. Available in PDF, EPUB and Kindle. Book excerpt: Oxygen (O ) appeared in significant amounts in the Earth’s atmosphere over 2. 2 2 billion years ago, largely due to the evolution of photosynthesis by cyanobacteria (Halliwell 2006). The O molecule is a free radical, as it has two impaired electrons 2 that have the same spin quantum number. This spin restriction makes O prefer to 2 accept its electrons one at a time, leading to the generation of the so-called reactive oxygen species (ROS). The chemical nature of these species dictates that they can create damage in cells. This has contributed to the creation of the “oxidative stress” concept; in this view, ROS are unavoidable toxic products of O metabolism and 2 aerobic organisms have evolved antioxidant defences to protect against this tox- ity (Halliwell 1981; Fridovich 1998). Indeed, even in present-day plants, which are full of antioxidants, much of the protein synthetic activity of chloroplasts is used to replace oxidatively damaged D1 and other proteins (Halliwell 2006). Yet, the use of the “oxidative stress” term implies that ROS exert their effects through indiscriminate widespread inactivation of cellular functions. In this context, ROS must not be able to react with lipids, proteins or nucleic acids in order to avoid any damage to vital cellular components. However, genetic evidence has suggested that, in planta, purely physicoche- cal damage may be more limited than previously thought (Foyer and Noctor 2005).
Book Synopsis Sensors for Environment, Health and Security by : M.-I. Baraton
Download or read book Sensors for Environment, Health and Security written by M.-I. Baraton and published by Springer Science & Business Media. This book was released on 2008-11-25 with total page 501 pages. Available in PDF, EPUB and Kindle. Book excerpt: The NATO Advanced Study Institute on “Sensors for Environment, Health and Security: Advanced Materials and Technology” was held in Vichy (France) on September 16–27, 2007 where more than 65 participants, ranging from Ph. D. students to experienced senior scientists, met and exchanged ideas and know-how in a friendly atmosphere. The present book intends to cover the main topics of this NATO ASI through 32 chapters distributed over two parts (Part I: “Materials and Technologies” and Part II: “Applications to Environment, Health and Security”). The scientific programme of the NATO ASI consisted in 28 1-hour lectures given by 14 invited lecturers, 5 additional 1-hour lectures given by seminar speakers, 22 oral presentations by selected ASI participants and a poster session. The programme was divided into four sessions: (1) Advanced materials and technologies; (2) Sensors for environment; (3) Sensors for health; (4) Sensors for security. During the “Advanced Materials and Technologies” session (Part I of the present book), the lectures were dedicated to critical analyses of current methods for the synthesis of materials, nanomaterials (nanoparticles, nanowires, nanotubes, ...) and nanocomposites to be used for the fabrication of sensing devices, mainly semiconductor sensors. Among the synthesis methods, chemical (sol-gel, etc. ) and physical methods (laser deposition, DC magnetron sputtering, etc. ) were discussed. Several lectures addressed characterization techniques and it was concluded that the physical and chemical control of the materials/nanomaterials, including surface chemistry, remains a key issue for the reproducibility of the final device.

Available in PDF, EPUB and Kindle. Book excerpt: Photodegradation of Water Pollutants, the only complete survey available of current photocatalytic methods for treating water pollutants, covers all aspects of light-stimulated detoxification. Ideal for researchers and students, this new book explains methods for pollution treatment that have proven more effective than conventional biodegradation. Photodegradation of Water Pollutants examines advanced oxidation processes that have been successful in treating the chemical substances produced by industrial effluents and intensive agriculture. These oxidation processes include irradiation with ultraviolet or visible light, the use of homogenous sensitizers, such as dyes, and the use of heterogeneous photocatalysts, such as dispersed semiconductors. In addition, Photodegradation of Water Pollutants addresses the naturally occurring self-cleaning of some pollutants in sunlit surface waters, as well as several alternative non-photochemical approaches to water treatment. Available treatment options are discussed for the main groups of water pollutants, including toxic inorganic ions (cyanides, heavy metals), hydrocarbon derivatives (oil spills, surfactants, pulp and paper wastes), halocarbons, organo-N, organo-P, and organo-S compounds. The text also contains a unique section on the economics of advanced oxidation pollution treatments.
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.
Book Synopsis Psoralen Dna Photobiology by : Francis P. Gasparro
Download or read book Psoralen Dna Photobiology written by Francis P. Gasparro and published by CRC Press. This book was released on 2018-01-18 with total page 257 pages. Available in PDF, EPUB and Kindle. Book excerpt: In one form or another psoralens have been in use dating back to biblical times for the treatment of depigmented patches of skin. However, it has only been in the past 40 years that the structure and function of psoralens have been elucidated. Although several volumes have been published on photobiology and photomedicine, no one volume has ever been devoted to the psoralen photobiology. In these two volumes we focus on the properties and uses of photoactivated psoralens.In these volumes the various aspects of psoralens are presented in a review of the field as it stands in mid 1986. In retrospect, we may find that this particular time was crucial in the development of new therapeutic modalities as many of the applications of modem molecular biology are beginning to impact on the practice of medicine.This book was written with two purposes in mind. First, to serve as an update (the last collective review of the field was in 1982). Second, it is hoped that newcomers to the fields of photobiology andphotomedicine both scientists and clinicians would find it a useful introduction.
