Book Description
Research on the study of membrane toxicity has advanced a great deal in a relatively short period of time, prompting scientists to re-examine the problems associated with carriers, receptors and reactors to toxic substances. This book presents current research on the responses of membranes to toxic sub stances both by direct observation of macromolecules reacting with these substances and by inference from data on the bio chemical responses of cells and cell fractions. Two basic areas of membrane toxicity are analyzed by a large number and variety of scientists in this field. The first area is the effect of various toxic substances on membrane structure and function. The second area is where the membrane serves as the site of rate limiting step of the transport of various toxic substances. The aim of the book is to evaluate present concepts of membrane structure and function in relation to exposure to envir onmental toxicants. The book is divided into five sessions: 1. Xenobiotics and Membrane Transport 2. Cellular Responses to Toxins 3. Effects of Membranes and Receptors 4. Modification of Membrane Function by Toxicological Agents 5. Toxic Chemicals as Molecular Probes of Membrane Structure and Function Each paper is generally concluded by an edited discussion which contains many useful and interesting additional insights in each subject area. v ACKNOWLEDGEMENT We gratefully acknowledge the support provided for this conference by the U. S. Energy Research and Development Administration, the Environmental Protection Agency and the University of Rochester.

Book Description
Cellular toxicology has entered a new era. No longer are we concerned only with necrotic cell death produced by severe, acute insult (often to multiple intracellular targets) leading to disruption of the cell membrane. New advances in molecular and cellular biology are allowing the dissection of mechanisms of cell death involving more subtle targets within the cell. Toxicology has been very important, not only in understanding the mechanisms, nature, and severity of toxicity and thereby helping in risk assessment, but toxicology has also played a very important role in helping to understand basic biological processes. Historically this has perhaps been most evident in the use of toxic agents to interfere with specific reactions in the body and hence help to dissect out the mechanisms of metabolic processes. For example, the use of chemical inhibitors was very important in understanding the process of oxidative phosphorylation, or the tricarboxylic acid cycle. More recent examples are seen herein where toxicology interfaces with, for example structural biology in the study of the cytoskeletal components and their interactions. Indirectly, an understanding of the mechanisms of endogenous protective systems also improves knowledge of basic cell biology. Toxic insult and manipulation of cell signalling and control mechanisms in cell growth and differentation also highlight how important the discipline of cell toxicity has been and will continue to be a major contributor to our understanding of basic issues in the biological and biomedical sciences. This book offers selected reviews of some of the principal molecular mechanisms of cell toxicity.

Book Description
Focuses on the application of membrane technologies in removing toxic metals\metalloids from water. Particular attention is devoted to the removal of arsenic, uranium, and fluoride. These compounds are all existing in the earth’s crust at levels between two and five thousands micrograms per kg (parts per million) on average and these compounds can be considered highly toxic to humans, who are exposed to them primarily from air, food and water. In order to comply with the new maximum contaminant level, numerous studies have been undertaken to improve established treatments or to develop novel treatment technologies for removing toxic metals from contaminated surface and groundwater. Among the technologies available, applicable for water treatment, membrane technology has been identified as a promising technology to remove such toxic metals from water. The book describes both pressure driven (traditional processes, such as Nanofiltration, Reverse Osmosis, Ultrafiltration,etc) and more advanced membrane processes (such as forward osmosis, membrane distillation, and membrane bio-reactors) employed in the application of interest. Key aspect of this book is to provide information on both the basics of membrane technologies and on the results depending on the type of technology employed.

Book Description
This book mainly focuses on advances made over the past 10 years regarding the exposure, metabolism, transformation, toxicity, molecular mechanism and biomarkers for emerging chemicals in humans. A hot topic in the field of environmental health, the term “emerging chemicals” refers to a class of compounds that are frequently encountered and potentially harmful to the natural environment and human health. They are also the preferred target substances for future environmental control measures. The list of emerging chemicals includes pharmaceutical and personal care products (PPCPs), endocrine disruptor chemicals (EDC), persistent organic pollutants (POPs), and nanomaterials. However, the environmental and health hazard characteristics of many emerging chemicals remain unclear. The aim of this book is to stimulate further research in new directions by providing novel and provocative insights into the exposure assessment of and potential mechanisms regarding emerging chemicals in humans. It also offers a state-of-the-art report on recent discoveries concerning emerging chemicals and where the field is headed.

Book Description
Alzheimer’s disease is an increasingly common form of dementia and despite rising interest in discovery of novel treatments and investigation into aetiology, there are no currently approved treatments that directly tackle the causes of the condition. Due to its multifactorial pathogenesis, current treatments are directed against symptoms and even precise diagnosis remains difficult as the majority of cases are diagnosed symptomatically and usually confirmed only by autopsy. Alzheimer’s Disease: Recent Findings in Pathophysiology, Diagnostic and Therapeutic Modalities provides a comprehensive overview from aetiology and neurochemistry to diagnosis, evaluation and management of Alzheimer's disease, and latest therapeutic approaches. Intended to provide an introduction to all aspects of the disease and latest developments, this book is ideal for students, postgraduates and researchers in neurochemistry, neurological drug discovery and Alzheimer’s disease.

Book Description
Biological membranes are the essential structuring elements of all living cells. Many enzymatic reactions take place at the membrane-water interface. To gain detailed insight into membrane properties, it is therefore of great importance to understand the complex nature of the interactions of membrane proteins with lipids. Lipid-Protein Interactions: Methods and Protocols provides a selection of protocols to examine protein-lipid interactions, membrane and membrane protein structure, how membrane proteins affect lipids and how they are in turn affected by the lipid bilayer and lipid properties. The methods described here are all actively used, complementary, and necessary to obtain comprehensive information about membrane structure and function. They include label-free approaches, imaging techniques and spectroscopic methodologies. Written in the successful Methods in Molecular BiologyTM series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible protocols, and notes on troubleshooting and avoiding known pitfalls. Authoritative and easily accessible, Lipid-Protein Interactions: Methods and Protocols seeks to serve both professional and novices with its wide range of the methods frequently used in this area of research.
