As the title suggests, Isotope Effects in the Chemical, Geological and Bio Sciences deals with differences in the properties of isotopically substituted molecules, such as differences in the chemical and physical properties of water and the heavy waters. Since the various fields in which isotope effects are applied do not only share fundamental principles but also experimental techniques, this book includes a discussion of experimental apparatus and experimental techniques.

Isotope Effects in the Chemical, Geological and Bio Sciences is an educational monograph addressed to graduate students and others undertaking isotope effect research. The fundamental principles needed to understand isotope effects are presented in appropriate detail. While it is true that these principles are more familiar to students of physical chemistry and some background in physical chemistry is recommended, the text provides enough detail to make the book an asset to students in organic and biochemistry, and geochemistry.

All three peroxisome proliferator-activated receptor (PPAR) subtypes share a high degree of structural homology but differ in function, tissue distribution and ligand specificity.

In Peroxisome proliferator-Activated Receptors: Methods and Protocols, renowned experts in the PPAR arena provide detailed protocols for investigating these receptors. Chapters contain methods ranging from the cloning of receptors to their knockdown, to protocols exploring posttranslational modifications of PPARs and coactivators, as well as receptor subcellular localization. Also assembled are methods to evaluate the involvement of these receptors in behavior functions, an emerging facet in PPAR research. Written in the successful Methods in Molecular Biology (TM) 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. With its well-honed methodologies, Peroxisome proliferator-Activated Receptors: Methods and Protocols, will be a useful resource for all seeking to advance their knowledge of this field.

More than two third of the surface area of our planet is covered by oceans and assessment of the marine biodiversity is a challenging task. With the increasing global population, there is a tendency to exploit marine recourses for food, energy and other requirements. This puts pressure on the fragile marine environment and needs sustainable conservation efforts. Marine species identification using traditional taxonomical methods are often burdened with taxonomic controversies. Here in this book we will discuss the comparatively new concept of DNA barcoding and its significance in marine perspective. This molecular technique can be helpful in the assessment of cryptic species which are widespread in marine environment, and can also be used to link the different life cycle stages to the adult which is difficult to accomplish in marine ecosystems. Other advantages of DNA barcoding include authentication and safety assessment of seafood, wildlife forensics, conservation genetics and detection of invasive alien species (IAS). Global DNA barcoding efforts in the marine habitat include MarBOL, CeDAMar, CMarZ, SHARK-BOL, etc. DNA barcoding of different marine groups ranging from the microbes to mammals is to be revealed. In conjugation with newer and faster techniques like high throughput sequencing, DNA barcoding is serving as an effective modern tool in marine biodiversity assessment and conservation.

This volume describes high-throughput approaches to a series of robust, established methodologies in molecular genetic studies of population samples. Such developments have been essential not only to linkage and association studies of single-gene and complex traits in humans, animals and plants, but also to the characterisation of clone banks, for example in mapping of genomes. Chapters have been written by developers or highly experienced end-users concerned with a diverse array of biological applications. The book should appeal to any researcher for whom costs and throughput in their genetics laboratory have become an issue.

All forms of life depend on a variety of heavy metal ions. Nearly one-third of all gene products require a metal ion for proper folding or function. However, even metals generally regarded as non-poisonous are toxic at higher concentrations, including the essential ones. Thus, sensitive regulation of metal uptake, storage, allocation and detoxification is needed to maintain cellular homeostasis of heavy metal ions.

Molecular Microbiology of Heavy Metals includes chapters on allocation of metals in cells, metal transporter, storage and metalloregulatory proteins, cellular responses to metal ion stress, transcription of genes involved in metal ion homeostasis, uptake of essential metals, metal efflux and other detoxification mechanisms. Also discussed are metal bioreporters for the nanomolar range of concentration and tools to address the metallome. Chapters in the second part cover specific metals such as Fe, Mn, Cu, Ni, Co, Zn and Mo as key nutrient elements and Ag, As, Cd, Hg and Cr as toxic elements.

Folding for the Synapse addresses the current view on how protein folding and misfolding, controlled by molecular chaperones, contribute to synapse function and dysfunction. Molecular chaperones have been studied in relation to de novo protein folding, but there is increasing awareness that chaperone function is required for the regulation of protein dynamics when functioning physiologically as an isolated moiety or part of a protein complex. This book will introduce both important concepts of folding machineries and give examples of the biological relevance of further chaperone functions.

Sodium reabsorbing epithelia play a major role in whole-body sodium homeostasis. Some examples of sodium regulating tissues include kidney, colon, lung, and sweat ducts. Sodium transport across these membranes is a two-step process: entry through an amiloride-sensitive sodium channel and exit via the ouabain-sensitive sodium/potassium ATPase. The sodium entry channels are the rate-limiting determinant for transport and are regulated by several different hormones. The sodium channels also play a significant role in a number of disease states, like hypertension, edema, drug-induced hyperkalemia, and cystic fibrosis. Amiloride-Sensitive Sodium Channels: Physiology and Functional Diversity provides the first in-depth exchange of ideas concerning these sodium channels, their regulation and involvement in normal and pathophysiological situations.
Key Features
* Summarizes current state of amiloride-sensitive sodium channel field
* Analyzes structure-function of epithelial sodium channels
* Discusses immunolocalization of epithelial sodium channels
* Examines hormonal regulation of sodium channels

* Considers mechanosensitivity of sodium channels
* Provides ideas on sodium channels and disease

This book represents the first serious attempt to explain the fundamental basis of ozonetherapy and is a relevant step towards achieving further progress. Ozone is now considered a real drug and, after reacting with body fluids, releases messengers and activates several mechanisms which are able to elicit multiple biological effects. The therapeutic window has been defined and, contrary to the dogma that ozone is toxic any way you deal with it', it has been shown that ozone toxicity can be tamed and even totally avoided.

New powerful methodologies have been devised and astonishing clinical results in vascular and infectious diseases have already been achieved. An exciting novelty is the induction of an adaptive response that implies the unsuspected possibility of arresting cell degeneration due to endogenous chronic oxidative stress. However, further basic and controlled clinical studies need to be performed to fully exploit ozone's therapeutic potentials and to establish the real validity of this therapy. Authoritative scientists and clinicians should abandon their prejudice and consider the profound difference between endogenous oxidative stress and the new concept of ozonetherapeutic shock'. If this happens, we could soon have a simple and inexpensive tool to restore health in millions of patients.

This book has been written in a plain scientific language and can be read by scientists and clinicians, as well as by patients keen on regaining a state of well being.

This book focuses on host-pathogen interactions at the metabolic level. It explores the metabolic requirements of the infectious agents, the microbial metabolic pathways that are dedicated to circumvent host immune mechanisms as well as the molecular mechanisms by which pathogens hijack host cell metabolism for their own benefit. Finally, it provides insights on the possible clinical and immunotherapeutic applications, as well as on the available experimental and analytical methods. The contributions break new ground in understanding the metabolic crosstalk between host and pathogen.

This thesis addresses two fundamental areas in contemporary organic chemistry: synthesis of natural products and catalytic asymmetric synthesis. Firstly, a new methodology, developed by our research group, which allows the asymmetric synthesis of lactones, a structural unit ubiquitous in natural products, was utilised in the synthesis of a number of natural product analogues that showed significant biological activity. Secondly, the development of a catalytic asymmetric synthesis of a key structural motif present in a number of natural products and pharmaceuticals was accomplished. During the course of this work we discovered dual stereo control, which is significant because it allows the configuration of a new stereo centre to be controlled by a simple change of proton source.

Natural products play an integral and ongoing role in promoting numerous aspects of scientific advancement, and many aspects of basic research programs are intimately related to natural products.

One of the challenges faced by every cell as well as by whole organisms is to maintain appropriate concentrations of essential nutrient metals while excluding nonessential toxic metals. Toward that end, all organisms have developed mechanisms for metal homeostasis and detoxification to maintain metal levels within physiological limits. This book brings together current knowledge of the molecular basis of metal homeostasis and detoxification in various eukaryotic model systems, including yeasts, plants, and mammals. It focuses on the cellular systems controlling metal transport, intracellular distribution, and immobilization as well as on systems regulating metal-dependent transcription. In addition to environmental aspects (including phytoremediation), the book treats the pathophysiology of metal deficiency and overload in relation to disease.

In the future' the decade of the 1990s will likely be viewed as a Golden Age for retinoid research. There have been unprecedented research gains in the understanding of retinoid actions and physiology; since the retinoid nuclear receptors were first identified and the importance of retinoic acid in develop mental processes was first broadly recognized in the late 1980s. Between then and now, our knowledge of retinoid action has evolved from one of a near complete lack of understanding of how retinoids act within cells to one of sophisticated understanding of the molecular processes through which retinoids modulate transcription. In this volume, we have tried to provide a comprehensive update of the present understanding of retinoid actions, with an emphasis on re cent advances. The initial chapters of the volume, or Section A, focus on the physicochemical properties and metabolism of naturally occurring retinoids: - N OY provides an uncommonly encountered view of retinoid effects from the perspective of the physiochemical properties of retinoids. - V AKIANI and BUCK lend a perspective on the biological occurrence and actions of retro- and anhydro-retinoids. Section B considers both the retinoid nuclear receptors and their mechanisms of action as well as synthetic retinoids that have been used exper imentally to provide mechanistic insights into receptor actions and have potential therapeutic use for treating disease: - PIEDRAFITA and PFAHL provide a comprehensive review of retinoid nuclear receptor biochemistry and molecular biology.

This book puts hydrogen sulfide in context with other gaseous mediators such as nitric oxide and carbon monoxide, reviews the available mechanisms for its biosynthesis and describes its physiological and pathophysiological roles in a wide variety of disease states. Hydrogen sulfide has recently been discovered to be a naturally occurring gaseous mediator in the body. Over a relatively short period of time this evanescent gas has been revealed to play key roles in a range of physiological processes including control of blood vessel caliber and hence blood pressure and in the regulation of nerve function both in the brain and the periphery. Disorders concerning the biosynthesis or activity of hydrogen sulfide may also predispose the body to disease states such as inflammation, cardiovascular and neurological disorders. Interest in this novel gas has been high in recent years and many research groups worldwide have described its individual biological effects. Moreover, medicinal chemists are beginning to synthesize novel organic molecules that release this gas at defined rates with a view to exploiting these new compounds for therapeutic benefit.
