This Volume features protocols for investigating the hydrocarbon- and lipid-specific activities of microbes. They include methods for studying chemotaxis, the colonisation of hydrocarbon surfaces, hydrocarbon uptake, respiration, nitrogen fixation, sulphate reduction, membrane stabilisation through cis-trans isomerisation of membrane fatty acids, and the production of biosurfactants and biopolymers in response to the presence of hydrocarbons. A protocol for studying the ability of microbes to control the concentration of hydrocarbons in their aqueous environment is also described, and phenotyping methods to reveal microbes' more general metabolic activities are presented. Several protocols for investigating acid production in connection with oil souring and biocorrosion by microbes in oil well, oil transportation and storage settings are presented. Lastly, protocols for measuring methanogenesis, as an example of microbial hydrocarbon production, are described.< Hydrocarbon and Lipid Microbiology ProtocolsThere are tens of thousands of structurally different hydrocarbons, hydrocarbon derivatives and lipids, and a wide array of these molecules are required for cells to function. The global hydrocarbon cycle, which is largely driven by microorganisms, has a major impact on our environment and climate. Microbes are responsible for cleaning up the environmental pollution caused by the exploitation of hydrocarbon reservoirs and will also be pivotal in reducing our reliance on fossil fuels by providing biofuels, plastics and industrial chemicals. Gaining an understanding of the relevant functions of the wide range of microbes that produce, consume and modify hydrocarbons and related compounds will be key to responding to these challenges. This comprehensive collection of current and emerging protocols will facilitate acquisition of this understanding and exploitation of useful activities of such microbes.
This book shows the various sandwich assays that are constructed from recognition molecules, such as antibodies, oligonucleotide sequences and aptamers, developed as a result of nano- and biotechnology advances. It consists of ten chapters presenting interesting examples of these assays, organized according to the type of analytic methods (colorimetric, fluorescence, electrochemical, etc.) and detected objects (protein, nucleic acid, small-molecule, ion, etc.). It also includes a chapter discussing the introduction of sandwich assays as biosensors for the detection of a range of targets. It is an interesting and useful resource for a wide readership in various fields of chemical science and nanotechnology.
The largest collection of articles on the three major gene
families, this work ranges from enzymology to molecular biology to
physiological implications. The three gene families are related in
that the enzymes catalyse the NAD(P) dependent oxidation or
reduction of carbonyl containing substrates. The substrates are
important in diverse areas such as alcoholism, diabetes and cancer
related problems as well as simple detoxification. The scope of the
chapters, contributed by leading international scientists, is wide
and covers gene regulation to enzyme mechanisms and protein
structure. This is the only publication dealing in such depth with
just three gene families. An important reference for researchers in
toxicology and molecular biology.
This book encompasses the exciting developments and challenges in the fast-moving and rapidly expanding research field of single-molecule kinetic analysis of cell signaling that promises to be one of the most significant and exciting areas of biological research for the foreseeable future. Cell signaling is carried out by complicated reaction networks of macromolecules, and single-molecule analyses has already demonstrated its power to unravel complex reaction dynamics in purified systems. To date, most of the published research in the field of single-molecule processes in cells, focus on the dynamic properties (translational movements of the centre of mass) of biological molecules. However, we hope that this book presents as many kinetic analyses of cell signaling as possible. Although single-molecule kinetic analysis of cellular systems is a relatively young field when compared with the analysis of single-molecule movements in cells, this type of analysis is highly important because it directly relates to the molecular functions that control cellular behavior and in the future, single-molecule kinetic analysis will be largely directed towards cellular systems. Thus, we hope that this book will be of interest to all those working in the fields of molecular and cell biology, as well as biophysics and biochemistry.
Exemplifying and illustrating recent exciting advances in PNA chemistry, the second edition of Peptide Nucleic Acids: Methods and Protocols serves as a vital complement to the first edition of the book. Since the discovery of peptide nucleic acids, many interesting new derivatives and analogues in terms of nucleic acid recognition specificity and affinity have emerged. Also, as this detailed volume presents, great ingenuity in exploiting the unique properties of PNAs for a wide variety of applications within drug discovery, medical diagnostics, chemical biology and nanotechnology has unfolded. Written in the highly successful Methods in Molecular Biology series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and key tips on troubleshooting and avoiding known pitfalls. Peptide Nucleic Acids: Methods and Protocols, Second Edition serves as a source of useful specific methods and protocols as well as a source of inspiration for future developments.

This book has a particular interest in the methods and applications of metabolic engineering to improve the production and yield of a variety of different metabolites. The overall goal is to achieve a better understanding of the metabolism in different microorganisms, and provide a rational basis to reprogram microorganisms for improved biochemical production.
One ofthe major drivers in biological research is the establishment ofstructures and functions of the 50,000 or so proteins in our bodies. Each has a characteristic- dimensional structure, highly "ordered" yet "disordered"! This structure is essential for a protein's function and, significantly, it must be sustained in the competitive and complex environment of the living cell. It is now being recognised that when a cell loses control, proteins can se- assemble into more complex supermolecular structures such as the amyloid fibres and plaques associated with the pathogenesis of prion (CJD) or age-related (Alzheimer's) diseases. This is a pointer to the wider significance of the self-assembling properties of polypeptides. It has been long known that, in silk, polypeptides are assembled into- sheet structures which impart on the material its highly exploitable properties of flexibility combined with high tensile strength. But only now emerging is the recognition that peptides can Self-assemble into a wide variety of non-protein-like structures, including fibrils, fibres, tubules, sheets and monolayers. These are exciting observations and, more so, the potential for materials and medical exploitations is so wide ranging that over 80 scientists from Europe, USA, Japan and Israel. met 1-6 July 1999 in Crete, to discuss the wide-ranging implications of these novel developments. There was a spirit of excitement about the workshop indicative of an important new endeavor. The emerging perception is that of a new class of materials set to become commercially viable early in the 21st century.
Reviews of Environmental Contamination and Toxicology attempts to provide concise, critical reviews of timely advances, philosophy and significant areas of accomplished or needed endeavor in the total field of xenobiotics, in any segment of the environment, as well as toxicological implications.
Aminopeptidase N (APN)/CD13 and dipeptidylpeptidase IV (DPIV)/CD26 are proteolytic enzymes with ubiquitous occurrence in the body of animals and men. Their physiological roles depend on the respective location: in gut and kidney tubules degradation of smaller proteins and peptides serves in absorption of nutrients or reabsorption of amino acids from urine. In the CNS their important substrates are biologically active peptides (e.g. enkephalins). This book, however, has a strong focus on the role APN and DPIV play in the hematopoietic system, where again signal peptides and small proteins (cytokines) are among the most interesting substrates. Additionally, both the membrane bound peptidases play roles as partners in signal transduction of lymphocytes and monocytes, and inhibition of their enzymatic activity results in cell cycle arrest, inhibition of DNA synthesis and characteristic changes of cytokine secretion pattern of T cells. This knowledge more and more is used as the base of therapeutic strategies in the treatment of a variety of inflammatory and autoimmune diseases as well as of tumors of different origin. The editors themselves with their colleagues have contributed important results about APN and DPIV that are reviewed here, and additionally, most of the leading groups in this field from Europe, U.S., Australia and Japan have contributed reviews and latest, partially unpublished results of their work. Researchers of many fields of biosciences and medicine will find interesting reading in the book and new impulse for basic research as well as for clinical applications.
Theoretical chemistry has been an area of tremendous expansion and
development over the past decade; from an approach where we were
able to treat only a few atoms quantum mechanically or make fairly
crude molecular dynamics simulations, into a discipline with an
accuracy and predictive power that has rendered it an essential
complementary tool to experiment in basically all areas of science.
The diverse applications in this volume range from the study of allosteric regulation of ion channel activity using a classic mutagenesis approach, to the study of channel subunit stoichiometry using a novel biophysical approach based on fluorescence resonance energy transfer. Highlights include methods for heterologous expression of ion channels in cells, for determining channel structure-function, and for studying channel regulation.
Humans face the challenge of producing enough food to meet the
demands imposed by economic, biological and agricultural factors:
rising population; rising income; and an expectation of higher
quality food and a more diverse diet; decreasing amount of land
available for food production; lowering environmental impact of
agricultural practices and preserving biodiversity.

International concern in scientific, industrial, and governmental communities over traces of xenobiotics in foods and in both abiotic and biotic environments has justified the present triumvirate of specialized publications in this field: comprehensive reviews, rapidly published research papers and progress reports, and archival documentations. These three international publications are inte grated and scheduled to provide the coherency essential for nonduplicative and current progress in a field as dynamic and complex as environmental contamina tion and toxicology. This series is reserved exclusively for the diversified litera ture on ''toxic'' chemicals in our food, our feeds, our homes, recreational and working surroundings, our domestic animals, our wildlife and ourselves. Tre mendous efforts worldwide have been mobilized to evaluate the nature, pres ence, magnitude, fate, and toxicology of the chemicals loosed upon the earth. Among the sequelae of this broad new emphasis is an undeniable need for an articulated set of authoritative publications, where one can find the latest impor tant world literature produced by these emerging areas of science together with documentation of pertinent ancillary legislation. Research directors and legislative or administrative advisers do not have the time to scan the escalating number of technical publications that may contain articles important to current responsibility. Rather, these individuals need the background provided by detailed reviews and the assurance that the latest infor mation is made available to them, all with minimal literature searching."

It has become clear that tumors arise from excessive cell proliferation and a c- responding reduction in cell death. Tumors result from the successive accumulation of mutations in key regulatory target genes over time. During the 1980s, a number of oncogenes were characterized, whereas from the 1990s to the present, the emphasis shifted to tumor suppressor genes (TSGs). It has become clear that oncogenes and tumor suppressor genes function in the same pathways, providing positive and ne- tive growth regulatory activities. The signaling pathways controlled by these genes involve virtually every process in cell biology, including nuclear events, cell cycle, cell death, cytoskeletal, cell membrane, angiogenesis, and cell adhesion effects. Tumor suppressor genes are mutated in hereditary cancer syndromes, as well as somatically in nonhereditary cancers. In their normal state, TSGs control cancer development and p- gression, as well as contribute to the sensitivity of cancers to a variety of therapeutics. Understanding the classes of TSGs, the biochemical pathways they function in, and how they are regulated provides an essential lesson in cancer biology. We cannot hope to advance our current knowledge and to develop new and more effective therapies without understanding the relevant pathways and how they influence the present approaches to therapy. Moreover, it is important to be able to access the powerful tools now available to discover these genes, as well as their links to cell biology and growth control.

Antibodies tagged with fuorescent markers have been used in histochemistry for over 50 years. Although early applications were focused on the detection of microbial antigens in tissues, the use of immunocytochemical methods now has spread to include the det- tion of a wide array of antigens including proteins, carbohydrates, and lipids from virtually any organism. Today, immunohistochemistry is widely used to identify, in situ, various components of cells and tissues in both normal and pathological conditions. The method gains its strength from the extremely sensitive interaction of a specifc antibody with its antigen. For some scientifc areas, books have been published on applications of immu- cytochemical techniques specifc to that area. What distinguished Immunocytochemical Methods and Protocols from earlier books when it was frst published was its broad appeal to investigators across all disciplines, including those in both research and clinical settings. The methods and protocols p- sented in the frst edition were designed to be general in their application; the accompa- ing "Notes" provided the reader with invaluable assistance in adapting or troubleshooting the protocols. These strengths continued to hold true for the second edition and again for the third edition. Since the publication of the frst edition, the application of immuno- tochemical techniques in the clinical laboratory has continued to rise and this third edition provides methods that are applicable to basic research as well as to the clinical laboratory.

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 thesis offers readers a comprehensive introduction to amyloid proteins and the computational methods used with them. Katrine Skeby critically assesses and compares both the literature and the experiments performed by other researchers, which further elevates the quality and relevance of her own work. Amyloid proteins are highly complex, and this research provides unparalleled insights, especially with regard to the origin of cytotoxicity and to developing technologies for early detection, revealing in detail the molecular mechanisms behind hIAPP behavior. Several studies within the thesis answer difficult questions which promote future research into the properties of amyloid proteins. |
