Описание: Much of the progress in adapting polymer materials for use in bio-material applications has been achieved through irradiation techniques. This volume collects information on the topic for academic and industrial researchers.
Описание: The study of electromagnetic bioeffects is multidisciplinary; it draws heavily from the disciplines of physics, engineering, mathematics, biol- ogy, chemistry, medicine, and environmental health. This book is about these disciplines and how they mutually integrate in the study of electromagnetic pathophysiology. Over aperiod of years, the authors have become increasingly aware of the difficulty in locating information concerning interaction of electro- magnetic energy and biological tissues. There are numerous reports and publications, but no single comprehensive source in the American literature where such information is readily accessible. Regrettably, much of the importantinformation is contained in government documents and reports, some of which are inaccessible, or spread through many diverse journals, making retrieval and analysis of the material difficult. Although this book is primarily clinically oriented, it also focuses on those biophysical, biochemical, and fundamental molecular studies and findings that provide the basis for understanding the presence or absence of pathophysiological manifestations of exposure to radiofrequency, including microwave, energies. Detailed discussion and analysis of the relevant comprehensive physics, engineering, and biophysics are con- tained in Chapters 2-5. Because the treatment is multidisciplinary, wherever possible analy- sis is begun with basic background information that may appear elementary to some readers but is essential to understanding for those from a different discipline. Most confusion and controversies that exist in the field today arise from individuals of one discipline not appreciating basic facts or theories from another.
Описание: Edited and authored by pioneers and experts with extensive research experience in the field, this is the first book to specifically focus on applications of conjugated polymers in biology and biomedicine, covering materials science, physical principles, and nanotechnology.

Описание: This book provides an overview of the induction mechanism of imposex caused by organotin compounds in gastropods, as well as fundamental information on the physiology and biochemistry of reproduction in mollusks. Are the sex hormones of gastropod mollusks vertebrate-type steroids, or neuropeptides? What about lipid disturbance and membrane toxicity due to organotin compounds? The book also discusses the latest findings on the role of nuclear receptors, such as retinoid X receptor (RXR), retinoic acid receptor (RAR) and peroxisome proliferator-activated receptor (PPAR), in the development of imposex in gastropods. Further, it describes the current state of contamination by organotins in the marine environment and gastropod imposex, with a special focus on Europe and Asia, introduces readers to analytical techniques for organotin compounds, and assesses the contamination and adverse effects of alternatives to organotin-based antifouling paints.Imposex, a superimposition of male genital tracts, such as penis and vas deferens, on female gastropod mollusks, is known as a typical phenomenon or consequence of endocrine disruption in wildlife. Imposex is typically induced by very low concentrations of organotin compounds, such as tributyltin (TBT) and triphenyltin (TPhT) from antifouling paints on ships and fishing nets. Reproductive failure may be brought about in severely affected stages of imposex, resulting in population decline and/or mass extinction. Thus, gastropod imposex has been recognized as a critical environmental pollution issue. Although gastropod imposex is also highly interesting for the biological sciences because of its acquired pseudohermaphroditism and/or sex change by certain chemicals, such as TBT and TPhT, the mechanism that induces the development of imposex remains unclear, possibly due to our limited understanding of the endocrinology of gastropod mollusks. This book offers a useful guide for professionals and students interested in the fields of aquatic biology, invertebrate physiology, ecotoxicology and environmental science.
