A biosensor is a device in which a bioactive layer lies in direct contact with a transducer whose responses to change in the bioactive layer generate eloctronic signals for interpretation. The bioactive layer may consist of membrane-bound enzymes, anti-bodies, or receptors. The potential of this blend of electronics and biotechnology includes the direct assay of clinically important substrates (e.g. blood glucose) and of substances too unstable for storage or whose concentrations fluctuate rapidly. Written by the leading researchers in the field, this book reflects the most current developments in successfully constructing a biosensor. Major applications are in the fields of pharmacology, molecular biology, virology and electronics.

Biochemistry And Genetics of RecQ-Helicases provides a background into the role of helicases in general and RecQ helicases specifically in DNA repair. Helicases- enzymes which break down hydrogen bonds between nucleic acid strands in a nucleoside triphosphate-dependent manner-are ubiquitous in biology, participating in processes as diverse as replication, repair, recombination, transcription, and translation. The RecQ-family helicases are a group of helicases which have important roles in the maintenance of genomic stability in many organisms. In humans, mutations in three RecQ-family helicases lead to disease. This book thoroughly examines these helicases. Mutations in the BLM gene lead to Bloom syndrome, a disorder characterized by a susceptibility to many types of cancer. Mutations in the WRN gene cause Werner syndrome, a disease which in some respects resembles premature aging. Finally, mutations in a newly characterized RecQ-family member, RECQ4, may lead to the very rare recessive disorder Rothmund-Thomson syndrome, a condition characterized by developmental abnormalities and some aging-like manifestations. This book is intended for any researchers invested in these particular disorders, or with a general interest in DNA.

Stresses which arise in bioreactors can influence process performance considerably. Recent molecular biological investigations indicate that stress caused by fluid dynamical effects and extreme values of process variables and toxic substances cause similar responses in the cells. These molecular fundamentals, as well as quantitative evaluation of fluid dynamical stresses and, their effects on microorganisms, animal and plant cells and proteins are treated in this volume.

Kinetic Theory of granular Gases provides an introduction to the rapidly developing theory of dissipative gas dynamics as it has been developed mainly during the past decade. The book is aimed at readers from the advanced undergraduate level onwards and leads up to the present state of research. The text is self-contained, in the sense that no mathematical or physical knowledge is required that goes beyond standard undergraduate physics courses. The material is adequate for a one-semester course and contains chapter summaries as well as exercises with detailed solutions. Special emphasis is put on a microscopically consistent description of pairwise particle collisions which leads to an impact-velocity dependent coefficient of restitution. The description of the many-particle system, based on the Boltzmann equation, starts with the derivation of the velocity distribution function, followed by the investigation of self-diffusion and Brownian motion. Using hydrodynamical methods, transport processes and self-organized structure formulation are studies. An appendix gives a brief introduction to event-driven molecular dynamics. A second appendix describes a novel mathematical technique for the derivation of the kinetic properties which allows for the application of computer algebra. The book is accompanied by a web page where the molecular dynamics program as well as the computer-algebra programs are provided.

Tingyue Gu's second edition provides a comprehensive set of nonlinear multicomponent liquid chromatography (LC) models for various forms of LC, such as adsorption, size exclusion, ion-exchange, reversed-phase, affinity, isocratic/gradient elution and axial/radial flow LC. Much has advanced since the first edition of this book and the author's software, described here, is now used for teaching and research in 32 different countries. This book comes together with a complete software package with graphical user interface for personal computers, offered free for academic applications. Additionally, this book provides detailed methods for parameter estimation of mass transfer coefficients, bed voidage, particle porosity and isotherms. The author gives examples of how to use the software for predicitons and scale-up. In contrast to the first edition, authors do not need to deal with complicated math. Instead, they focus on how to obtain a few parameters for simulation and how to compare simulation results with experimental data. After reading the detailed descriptions in the book, a reader is able to use the simulation software to investigate chromatographic behavior without doing actual experiments. This book is aimed at readers who are interested in learning about LC behaviors and at those who want to scale up LC for preparative- and large-scale applications. Both academic personnel and industrial practitioners can benefit from the use of the book. This new edition includes: - New models and software for pellicular (cored) beads in liquid chromatography - Introduction of user-friendly software (with graphical user interface) - Detailed descriptions on how to use the software - Step-by-step instructions on parameter estimation for the models - New mass-transfer correlations for parameter estimation - Experimental methods for parameter estimation - Several actual examples using the model for product development and scale-up - Updated literature review

With innovations in sports equipment, doping methods and human engineering on the horizon, the ethical issues raised by such technology have become noticeably acute. The problematization of technology in sport has gone largely unnoticed in historical, philosophical and policy studies of sport, but this study traces the origins, present contexts and future of sport technology. This volume speaks to a multi-disciplinary audience, developing theory of technology and sport. It provides a foundation for theorising technological issues in sport, building upon themes in cultural studies of the cyborg, otherness and gender. The book begins with an initial contextualising of sport technology, tracing the historical roots of key moments of technological development. Subsequently, chapters work towards theorising technology in sport, providing a socio-philosophical context to ways of understanding technology. From here, applied philosophical and ethical issues focus on the themes of fearing the other, virtual reality in sport, and the use of genetic technology to augment athletic performances. Perspectives draw upon a range of theory, including the works of Alasdair MacIntyre, Jacques Ellul, Don Ihde, Donna Haraway, Andrew Feenberg, Charles Taylor, Langdon Winner, Hilary Putnam, Richard Rorty, John Rawls and Michel Foucault. This book should be relevant to scholars of sport or technology from a diverse range of perspectives. Framed by the broad disciplines of history, philosophy and policy, the issues discussed can have importance for subjects as diverse as theoretical medicine, philosophy of sport and policy studies in technology. For the latter, the aim is to provide a theoretical and ethical grounding for a coherent theory of sport performance.

Recent advances in biotechnology in areas as diverse as agriculture, the environment, food, and healthcare have led to much debate and media attention. This unique reference resource for advanced high school students and teachers explores the science behind these new technologies and examines the stakeholders and their stakes in the various debates. The author presents views of scientists, doctors, insurance companies, and big businesses, among others, on such issues as genetic testing, patenting of human gene sequences, cloning, and genetically engineered food.

Each chapter addresses a specific issue with the goals of helping readers understand all the different ways biotechnology is being explored and implemented in our lives today, as well as to critically perceive the arguments being made concerning these issues. Students will learn there is more to biotechnology than cloning sheep, that it is also used for such purposes as making cheese and beer. Each topic is presented as a Case Study describing of a range of technologies and a diversity of stakeholders that will allow users to draw their own conclusions. This introduction to the technologies and the debates surrounding them also encourages students to take advantage of the many available sources for further research, particularly on the Internet.

The introduction of high-performance liquid chromatography (HPLC) to the analysis of peptides and proteins some 25 years ago revolutionized the biological sciences by enabling the rapid and sensitive analysis of peptide and protein structure through the exquisite speed, sensitivity, and resolution that can be easily obtained. Today, HPLC in its various modes has become the pivotal technique in the characterization of peptides and proteins and currently plays a critical role in both our understanding of biological processes and in the development of peptide- and protein-based pharmaceuticals. The number of applications of HPLC in peptide and protein purification continues to expand at an extremely rapid rate. Solid-phase peptide synthesis and recombinant DNA techniques have allowed the production of large quantities of peptides and proteins that need to be highly purified. HPLC techniques are also used extensively in the isolation and characterization of novel proteins that will become increasingly important in the postgenomic age. The design of multidimensional purification schemes to achieve high levels of product purity further demonstrates the power of HPLC techniques not only in the characterization of cellular events, but also in the production of pepti- and protein-based therapeutics. HPLC continues to be at the heart of the analytical techniques with which scientists in both academia and in industry must arm themselves to be able to fully characterize the identity, purity, and potency of peptides and proteins.

This Volume provides protocols for the biochemical analysis of hydrocarbon- and lipid-relevant products, cell components and activities of microbes that interact with hydrophobic compounds. They include methods for the extraction, purification and characterisation of surface tension-reducing bioemulsifiers and biosurfactants that increase the surface area and hence bioavailability of hydrophobic substrates. Protocols for the isolation and biochemical analysis of lipids and polyhydroxyalkanoates, food storage products made during nutrient abundance that represent important biotechnological products, are presented. The extraction of membrane lipid rafts, sub-organelles that fulfil important functional roles for the cell membrane, and the isolation and characterisation of membrane phospholipid biomarkers, are also described. The purification and characterisation of integral membrane hydrocarbon-oxidising enzymes are addressed. Lastly, two generic methods for the genetic analysis of catabolic pathways and analysis of ligand binding are presented. 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.

Antibiotics are truly miracle drugs. As a class, they are one of the only ones that actually cure disease as opposed to most drugs that only help relieve symptoms or control disease. Since bacteria that cause serious disease in humans are becoming more and more resistant to the antibiotics we have today, and because they will ultimately become resistant to any antibiotic that we use for treatment or for anything else, we need a steady supply of new antibiotics active against any resistant bacteria that arise. However, the antibiotics marketplace is no longer attractive for large pharmaceutical companies, the costs of development are skyrocketing because of ever more stringent requirements by the regulatory agencies, and finding new antibiotics active against resistant strains is getting harder and harder. These forces are all combining to deny us these miracle drugs when we need them the most. I provide a number of possible paths to shelter from this perfect storm.

It is the belief of the editors of this book that the recognition of block copolymers as being amphiphilic molecules and sharing common features with other well-studied amphiphiles will prove beneficial to both the surfactant and the polymer communities. An aim of this book is to bridge the two communities and cross-fertilise the different fields. To this end, leading researchers in the field of amphiphilic block copolymer self-assembly, some having a background in surfactant chemistry, and others with polymer physics roots, have agreed to join forces and contribute to this book.
The book consists of four entities. The first part discusses theoretical considerations behind the block copolymer self-assembly in solution and in the melt. The second part provides case studies of self-assembly in different classes of block copolymers (e.g., polyethers, polyelectrolytes) and in different environments (e.g., in water, in non-aqueous solvents, or in the absence of solvents). The third part presents experimental tools, ranging from static (e.g., small angle neutron scattering) to dynamic (e.g., rheology), which can prove valuable in the characterization of block copolymer self-assemblies. The fourth part offers a sampling of current applications of block copolymers in, e.g., formulations, pharmaceutics, and separations, applications which are based on the unique self-assembly properties of block copolymers.

The bioseparation engineering of today includes downstream process engineering such as waste water, material and gas treatment. Taking this tendency into account, bioseparation engineers gathered in Japan as a special research group under the main theme of "Recovery and Recycle of Resources to Protect the Global Environment."

The scope of this book is based on the conference, and deals not only with recent advances in bioseparation engineering in a narrow sence, but also the environmental engineering which includes waste water treatment and bioremediation. The contributors of this book cover many disciplines such as chemical engineering, analytical chemistry, biochemistry, and microbiology.

"Bioseparation Engineering" will stimulate young engineers and scientists who will develop bioseparation engineering further in the 21st century, and contribute to a world-wide attention to the global environment

Recombinant Proteins from Plants is one of the most exciting and fastest developing areas in biology. The latest molecular techniques are being applied to the exploitation of plants as novel expression systems for the p- duction and overproduction of heterologous and native proteins. Transgenic plant technology is currently used in three broad areas: the expression of - combinant proteins to improve crop quality by increasing disease/pest res- tance or increasing tolerance to stress, optimizing plant productivity and yield by the genetic manipulation of metabolic pathways, and the large-scale co- effective production of recombinant proteins for use as specialist industrial or therapeutic biomolecules. The intention of Recombinant Proteins from Plants is to provide c- prehensive and detailed protocols covering all the latest molecular approaches. Because the production oftransgenic plants has become routine in many la- ratories, coverage is also given to some of the more "classical" approaches to the separation, analysis, and characterization of recombinant proteins. The book also includes areas of research that we believe will become increasingly important in the near future: efficient transformation of monocots with Agrobacterium optimizing the stability of recombinant proteins, and a section highlighting the immunotherapeutic potential of plant-expressed proteins.

The increasing demand for environmentally friendly materials and the need for cheaper fibres points the search in the direction of natural products such as bark, leaves, scales or shells. The aim of this book is to provide a forum to review the recent advances in the area of plant and animal-based composites and identify possible trends for further developments.

Closing the gap between electrochemical engineering science and electrochemical technology, this volume is for all electrochemists and electrochemical engineers, metallurgists, engineers in chemical process, galvanic, metallurgical and electric power industries.

Current information in applied microbioogy is provided in this text supported by an extensive bibliography.

Aspects of genetic engineering research emphasized in this volume are applications to plants (crop plants and grass, both important for human needs) and new methodologies, such as Tar cloning, which make it much easier to isolate specific regions from complex genomes. Another subject discussed is linear DNA replication of prokaryotes.

Cell separation, which was once limited to merely being a basic technique for fractionating different cell populations, has come a long way in the last two decades. New, advanced and more speci?c and selective techniques have emerged as the demand for isolating a speci?c cell type for various biological applications has increased. Ef?cient and cost-effective techniques for fr- tionation and isolation of target cell types are necessary to provide pure cell populations for diagnostics, biotechnological and biomedical applications. One can see a considerable need, both in biomedical research and in di- nostic medicine, for the speci?c separation of a discrete population of cells from a mixture. For example, in the ?eld of tissue engineering, isolation of stemcellsfromtissuesororgansisofparticularlygreatimportance.Moreover, understanding cell developmental pathways becomes increasingly signi?cant as diagnosis and treatment of diseases turns more to the molecular level. The diagnosis of cell-related diseases requires methods of detection, isolation and theanalysisofindividualcells,regardlessoftheirrelativecontentinthetissue. Since cell-based therapies now turn towards more realistic medical options, developing an effective separation system for large-scale cell separation has becomechallengingresearchgoalforcellbiologistsandbiotechnologists.The ideal technique should provide in a short time a good yield of cells with high puritywhile maintaining cellfunction.Despite the growingneed formethods to separate cells into cell subpopulations, the existing cell-separation te- niques stillhave somelimitations when the desired degree ofperformance on apreparativescaleisrequired.Wewillseemoreresearchfocusinthisdirection in the future. The traditional techniques of micro?ltration, ultra?ltration and ultrac- trifugation, which exploit differences in cell size, shape and density, have remainedtheworkhorsesdespitelowspeci?cityandproblemswithscalingup.

The objectives of this Second Edition of Biotechnology: A Laboratory Course remain unchanged: to create a text that consists of a series of laboratory exercises that integrate molecular biology with protein biochemistry techniques while providing a continuum of experiments.
