    Book SynopsisWhen a biomaterial is placed inside the body, a biological response is triggered almost instantaneously. With devices that need to remain in the body for long periods, such interactions can cause encrustation, plaque formation and aseptic loosening on the surface. These problems contribute to the patient's trauma and increase the risk of death. Electrical properties, such as local electrostatic charge distribution, play a significant role in defining biological interactions, although this is often masked by other factors. This book describes the fundamental principles of this phenomenon before providing a more detailed scientific background. It covers the development of the relevant technologies and their applications in therapeutic devices such as MRSA-resistant fabrics, cardiovascular and urological stents, orthopaedic implants, and grafts. Academic and graduate students interested in producing a selective biological response at the surface of a given biomaterial will find the detailed coverage of interactions at the nanometre scale useful. Practitioners will also benefit from guidance on how to pre-screen many inappropriate designs of biomedical devices long before any expensive, animal or potentially risky clinical trials. Enhanced by the use of case studies, the book is divided in to four topical sections. The final section is dedicated to the application of related topics making the book unique in its pragmatic approach to combining high end interdisciplinary scientific knowledge with commercially viable new technologies. Contributing to the newly emerging discipline of 'nanomedicine', the book is written not only by experts from each relevant specialty but also by practitioners such as clinicians and device engineers from industry.Trade ReviewThe book originates from the activity of a BioElectricSurface consortium, funded by the European Commission under the FP-7 Nanosciences, Nanotechnologies, Materials and New Production Technologies (NMP) program and discusses the crucial role surface charge plays in the interaction between materials in biological and medical applications. The first part of the book covers new findings in biology, e.g. bone growth by charged hydroxyapatite and photocatalytic effect in doped titania and includes useful explanations of the many modern techniques used to create and measure electric charges at surfaces and intersurfaces. The first part of the book contains some very useful information, such as discussion of the polarization of hydroxyapatite, which increased bone growth on the negative surface while no growth was observed on the positive surface, and commentary on the increased photocatalytic activity of doped titania . This section also concisely, but thoroughly, analyses thermally stimulated depolarization current methods, the laser intensity modulation method of charge measurements, scanning probe, Kelvin probe force and electrostatic force microscopy, and the streaming potential measurement techniques used for wet cases. The techniques utilized for interfacial measurements, such as confocal laser scanning microscopy, are also covered in chapter 4. Part 2 describes many practical examples in which the surface interactions play an essential role. For example, chapter 5 discusses immobilized enzymes on porous surfaces in biocatalysts, drug delivery, and biosensors, while chapter 6 goes on to describe improvement of the extracellular matrix (ECM) by the interactions of host tissue cells with the implant surface Chapters 7, 8 and 9 discuss antibody immobilization on solid surfaces, adhesion, proliferation and differentiation of bone-forming cells with electrostatic charge at biomaterials surfaces and interactions of biofilm-forming bacteria with abiotic surfaces. Endothelial cells and smooth muscle cells on the biomaterials surfaces, interactions of bacteria and fungi on biofilms in hospital acquired infections and immunological response of electrostatic charge at the surface of biomaterials are covered in chapters 10, 11 and 12. Such elaborate discussions show the relevance of surface charge in biological interactions at and with non-biological surfaces and, I strongly believe, will provide a solid foundation for interested readers who are willing to bring innovative ideas of surface modifications to generate or control a specific biological response on implantable therapeutic devices. Part 3 of the book is a logical progression from parts 1 and 2, and describes some of the important applications where surface charge is believed to play a significant role. These include: Community and hospital acquired infections of methicillin-resistant staphylococcus aureus (MRSA), MRSA-resistant textiles, inhibition of encrustation in urological devices and the reduction of restenosis in cardiovascular stents. The book finishes with a general overview of a new class of materials, named as vector materials, where the interfaces between biomaterial and biological environment can be manipulated by the application of vectorial effects induced by electrical polarization. Surface charges are frequently experienced by the frictional electricity in textiles. The infection of bacteria and the restenosis of implanted stenosis are broadly concerned matters in the society. As a basic research, it is noteworthy that negatively charged hydroxyapatite induces new bone. The book shows that the study of electric charge in surfaces is important to understand the basic mechanism of all these matters. The many topics introduced in this book promises more rapid progress in future research. The abbreviation of technical words sometime hinders the understanding of sentences, but the subject index at the end of the book helps greatly to solve this difficulty. The arrangement of chapters is also well ordered. The Editor’s kind efforts are appreciated. -- Eiichi Fukada, Kobayasi Institute of Physical Research, Tokyo, Japan and Emeritus Scientist, RIKEN, Wako, JapanTable of ContentsElectrostatic Charge on Biomaterials Surface; Electrical modifications of biomaterials' surfaces: Beyond hydrophobicity and hydrophilicity; Photocatalytic effects in doped and undoped titania; Surface charge measurements on biomaterials in dry and wet conditions Measurements of surface and interfacial charge and morphology in electrically modified materials; Protein Interactions at the surface; Immobilisation of enzymes on porous surface; Fibrous proteins interactions with modified surfaces of biomaterials; Antibody immobilisation on solid surfaces: methods and applications; Cellular Interactions with Abiotic Surfaces; Interactions of bone forming cells with electrostatic charge at biomaterials surface; Interactions of biofilm-forming bacteria with abiotic surfaces; Endothelial cells and smooth muscle cells (SMC) interactions at biomaterials surfaces; Interactions of Bacteria and fungi at the surface; Immunological response of electrostatic charge at the surface of biomaterials; IV.

  • Morphogenesis and Pathogenicity in Fungi

    Springer-Verlag Berlin and Heidelberg GmbH & Co. KG Morphogenesis and Pathogenicity in Fungi

    1 in stock

    Book SynopsisInfectious fungal diseases continue to take their toll in terms of human suffering and enormous economic losses. Invasive infections by opportunistic fungal pathogens are a major cause of morbidity and mortality in immuno-compromised individuals. At the same time, plant pathogenic fungi have devastating effects on crop production and human health. New strategies for antifungal control are required to meet the challenges posed by these agents, and such approaches can only be developed through the identification of novel biochemical and molecular targets. However, in contrast to bacterial pathogens, fungi display a wealth of “lifestyles” and modes of infection. This diversity makes it extremely difficult to identify individual, evolutionarily conserved virulence determinants and represents a major stumbling block in the search for common antifungal targets. In order to activate the infection programme, all fungal pathogens must undergo appropriate developmental transitions that involve cellular differentiation and the introduction of a new morphogenetic programme. How growth, cell cycle progression and morphogenesis are co-ordinately regulated during development has been an active area of research in fungal model systems such as budding and fission yeast. By contrast, we have only limited knowledge of how these developmental processes shape fungal pathogenicity, or of the role of the cell cycle and morphogenesis regulators as true virulence factors. This book combines state-of-the-art expertise from diverse pathogen model systems to update our current understanding of the regulation of fungal morphogenesis as a key determinant of pathogenicity in fungi. Trade ReviewFrom the reviews:“This book describes the molecular basis of morphogenesis and pathogenicity in the fungi and highlights new approaches. … All the chapters are well organized and each chapter contains an introduction at the beginning and a conclusion at the last that can be very useful for the reader. … This book is very important to scientists, researchers and teachers as well as students who are interested in fungal morphogenesis and pathogenicity. Therefore this book should be available in all schools, research laboratories, community and university libraries.” (Kasun M.

    Book SynopsisModern Methods of Plant Analysis When the handbook Modern Methods of Plant Analysis was first introduced in 1954 the considerations were 1. the dependence of scientific progress in biology on the improvement of existing and the introduction of new methods; 2. the inavailability of many new analytical methods concealed in specialized journals not normally accessible to experimental plant biologists; 3. the fact that in the methods sections of papers the description of methods is frequently so compact, or even sometimes so incomplete, that experiments are difficult to reproduce. These considerations still stand today. The series was highly successful, seven volumes appearing between 1956 and 1964. Since today there is still a demand for the old series, the publisher has decided to resume publication of Modern Methods of Plant Analysis. It is hoped that the New Series will be as acceptable to those working in plant sciences and related fields as the early volumes undoubtedly were. It is difficult to single out the major reasons for success of any publication, but we believe that the methods published in the first series were up-to-date at the time and the descriptions as applied to plant material so complete in themselves that there was little need to consult other publications.Table of ContentsCell-Wall-Isolation, General Growth Aspects.- 1 Introduction.- 2 Isolation

    Book SynopsisMechanistische Überlegungen nehmen heute einen festen Platz in der Organischen Chemie ein: Welche Faktoren beeinflussen die Reaktivität eines Moleküls? Welche typischen Reaktionsprinzipien und -muster gibt es, und in welchen Schritten verlaufen organisch-chemische Reaktionen? Wie lassen sich Reaktionen steuern? Anhand moderner und präparativ nützlicher Reaktionen erläutert der Autor die Reaktionsprinzipien; klar und verständlich werden Konzepte herausgearbeitet, stets auch stereochemische Konsequenzen abgeleitet. Der Autor bietet Faustregeln zur Reaktivitätsabschätzung sowie Tips und Tricks für die Praxis. Die zweifarbige Gestaltung erhöht die Übersichtlichkeit und erleichtert das Verfolgen der Mechanismen. In der vorliegenden 3. Auflage wurden nach dem überwältigenden Verkaufserfolg der 2. Auflage die Fehler in Text und Grafiken korrigiert und die Literatur nochmals aktualisiert.

    Book SynopsisDie technischen Fortschritte und neuen Möglichkeiten der molekularen Biologie – Genomanalysen, Expressionsanalysen, konfokale Lasermikroskopie, Proteomics – lassen die Physiologie von Wirbeltieren, genauso wie die von Nicht-Wirbeltieren, in einem neuen Licht erscheinen. Bei der Darstellung der Endokrinologie von Mensch und Tier wird dieser Entwicklung Rechnung getragen: Die Schwerpunkte liegen auf Hormonbiochemie, Hormonphysiologie, Hormonrezeptoren, endokrinen Organen und Regelkreisen und der Regelung endokriner Rhythmen. Die Betrachtung des Hormonsystems reicht von seinen Ursprüngen bei Invertebraten, seiner Evolution, den Wechselwirkungen mit Nerven- oder Immunsystem bis zu Stoffwechselstörungen bei menschlichen Gen-Defekten. Die 4. Auflage ist deutlich erweitert. Das Thema Stoffwechsel nimmt, verteilt über mehrere Kapitel, eine wesentlich größeren Raum ein. Komplett neu ist auch die Embryologie der endokrinen Organe.Trade Review“... Zusammenfassend handelt es sich beim „Kleine/Rossmanith" um ein kompaktes Lehrbuch, das die wesentlichen Bereiche der Endokrinologie abdeckt und für den Einstieg in dieses spannende Fach zu empfehlen ist.” (Jan Tuckermann, in: BIOspektrum, Jg. 28, Heft 4, 2022) “… Das Buch stellt eine immense Fleißarbeit dar, alleine die bei den einzelnen' Kapiteln angeführten Literaturverzeichnisse haben einen Umfang, den man in den üblichen Lehrbüchern nur noch selten findet. Das macht dieses Lehrbuch aber zu einem nützlichen Nachschlagewerk für jeden, der sich über spezielle Probleme der Endokrinologie auch unter evolutionären und vergleichenden Aspekten informieren will.” (Prof. Dr. L.

    Book SynopsisFor centuries preparations containing resin from the root of Thapsia garganica L. (Fig. 1) have been used in Arabian and European medicine for treatment of pulmonary diseases, catarrh and as counterirritants for relief of rheumatic pains (1). The properties of the resin were described already by Theophrastos (372-287 B. C. ), Dioscorides (approximately A. D. 50), and Plinius (A. D. 24-79) (2). Radix Thapsiae and Resina Thapsiae have been included in several pharmacopoeias, the latest in the French pharmacopoeia from 1937. The two major active principles were about Fig. I.

    Book SynopsisWe are at a critical point in human history and that of the planet. In this book, a world leader in agricultural research, Professor Sayed Azam-Ali, proposes a radical transformation of our agrifood system. He argues that agriculture must be understood as part of global biodiversity and that food systems have cultural, nutritional, and social values beyond market price alone. He describes the perilous risks of relying on just four staple crops for most of our food and the consequences of our current agrifood model on human and planetary health.In plain language for the wider public, students, researchers, and policy makers, Azam-Ali envisions the agrifood system as a global public good in which its practitioners include a new and different generation of farmers, its production systems link novel and traditional technologies, and its activities encompass landscapes, urban spaces, and controlled environments. The book concludes with a call to action in which diversification of species, systems, knowledge, cultures, and products all contribute to The Ninth Revolution that will transform food systems for good.Related Link(s)

    Book SynopsisThe ABC of Acid-Base Chemistry provides physiologists, medical students, and physicians with an intelligible outline of the elements of physiological acid-base chemistry. This new edition of Horace W. Davenport's standard text takes into account different ways of looking at the problems of acid-base derived from new instrumentation. The exposition has been modified to allow the student to apply his understanding to other systems of description of the acid-base status. Although the pH system has been retained, there is increasing emphasis on the use of hydrogen ion concentration. Topics discussed include: partial pressure of gases, composition of alveolar gas, transport of oxygen and carbon dioxide in the blood, buffer action of hemoglobin and seperated plasma, oxygenated whole blood and reduced blood, concepts of base excess and base deficit, and chemical regulation of respiration.

This book recovers a forgotten history of the connections between radioactivity and the life sciences that existed long before the dawn of molecular biology.Trade Review"Radium and the Secret of Life probes the experimental and metaphorical connections between transmutation and mutation. As that coupling makes clear, it was a book waiting to be written.

    Book SynopsisToday's science tells us that our bodies are filled with molecular machinery that orchestrates all sorts of life processes. When we think, microscopic channelsopen and close in our brain cell membranes; when we run, tiny motorsspin in our muscle cell membranes; and when we see, light operates molecular switchesin our eyes and nerves. A molecular-mechanical vision of life has become commonplace in both the halls of philosophy and the offices of drug companies, where researchers are developing proton pump inhibitors or medicines similar to Prozac. Membranes to Molecular Machines explores just how late twentieth-century science came to think of our cells and bodies this way. This story is told through the lens of membrane research, an unwritten history at the crossroads of molecular biology, biochemistry, physiology, and the neurosciences, that directly feeds into today's synthetic biology as well as nano- and biotechnology. Mathias Grote shows how these sciences not only have made us think differently about life, they have, by reworking what membranes and proteins represent in laboratories, allowed us to manipulate life as active matterin new ways. Covering the science of biological membranes in the United States and Europe from the mid-1960s to the 1990s, this book connects that history to contemporary work with optogenetics, a method for stimulating individual neurons using light, and will enlighten and provoke anyone interested in the intersection of chemical research and the life sciencesfrom practitioner to historian to philosopher. The research described in the book and its central actor, Dieter Oesterhelt, were honored with the 2021 Albert Lasker Basic Medical Research Awardfor his contribution to the development of optogenetics.

His book is informative, accurate, and a good read all put together. -- Geoffrey Cooper, Boston University, author of The Cell: A Molecular Approach and Oncogenes This is a truly wonderful book. Stockwell's writing will open the door to a universe that many readers may know little about. Drugs are born, biotech companies are created, scientists' careers are made and unmade, egos are raised and dashed. This book is so readable, it is an absolute page-turner. Yet it is also authoritative and scientifically sophisticated, managing to distill a complex, changing field into a beautifully written, well-crafted story. -- Siddhartha Mukherjee, Columbia University, author of The Emperor of All Maladies: A Biography of Cancer By providing accessible explanations for the underlying biological and chemical principles that apply to the complex solutions he describes, Stockwell enables even the scientifically unsophisticated reader to gain a wider perspective on what future disease treatment might entail. Publishers Weekly This very readable, even exciting work takes us through the medical breakthroughs of the past century. Globe and Mail This book deserves a readership, and there is certainly a need for it. As a drug companyresearcher, I have often wished that more people understood what the field was likeand how simultaneously fascinating and frustrating it can be. -- Derek B. Lowe Cell In this well-researched look into the complexities of making medicines, a chemical biologist gives a history of drug making and details innovative methods of drug discovery. Science News Despite our current political paralysis, government leaders should listen to Stockwell and be certain to advance our capacity to generate the drugs that our society and the world need. Harvard Magazine The book is well organized and includes many interesting, clever analogies to explain what can be complicated scientific problems. Choice An engaging and rewarding read... -- Donald C. Lo Journal of Clinical Investigation The reader is not only left with a satisfying overview of the proud history and future challenges of finding new medicines but also encouragement that Stockwell and his contemporaries are creatively committed to academic drug discovery. -- David Kroll Nature Chemistry Stockwell writes well-his prose is accessible to the educated reader, irrespective of his or her background. All of the personalities, errors and successes in contemporary drug discovery are presented. Stockwell enlivens their stories with anecdotes... -- Garrett A. FitzGerald Nature Medicine It is impossible to read this relatively short book...without being captured by the author's optimism about the future of drug development. -- Robert C.

  • GPCR Molecular Pharmacology and Drug Targeting

    John Wiley & Sons Inc GPCR Molecular Pharmacology and Drug Targeting

    Book SynopsisG protein-coupled receptors (GPCRs) are a large protein family of transmembrane receptors vital in dictating cellular responses. GPCRs are involved in many diseases, but are also the target of around half of all modern medicinal drugs. Shifting Paradigms in G Protein Coupled Receptors takes a look at the way GPCRs are examined today, how they react, how their mutations lead to disease, and the many ways in which they can be screened for compounds that modulate them. Chemists, pharmacologists, and biologists will find essential information in this comprehensive reference.Trade Review"Additionally, the presentation of the fundamental concepts of GPCR biology by the authors, who are recognized experts in the GPCR field, is likely to be appreciated by students of pharmacology. . .

    Book SynopsisThe advances made in molecular biology have allowed scientists to manipulate DNA. This means that molecular biology has become a tool for answering scientific questions that may be quite unrelated to genetics and cell biology. The techniques have become a means to an end, rather than an end in themselves. This work deals with this area.Table of ContentsPreface Introduction and Background Part 1 Molecular Biology Experiment 1 Instructions for Pipetman Use Experiment 2 Preparation of Plasmid Template DNA Experiment 3 Estimation of Plasmid DNA Concentration PCR Amplification of LTB Gene from Plasmid DNA Experiment 4 Agarose Gel Eletrophoresis Recovery of PCR Product Experiment 5 Restriction Digest of LTB Insert Plate Preparation Experiment 6 Purification of Digested Insert and Vector by Agarose Gel Eletrophoresis Recovery of Digested Insert and Vector Experiment 7 Determination of DNA Concentrations Ligation of Insert into Vector Experiment 8 Transformation of Host Cells by Construct Experiment 9 Colony-pick PCR to Check for Presence of Insert Streak Plates with Potential Constructs Inoculate Cultures/Run PCR Experiment 10 Agarose Gel Electrophoresis to Verify Presence of Insert Purification of the Plasmid Construct using a Plasmid Miniprep Kit Experiment 11 DNA Concentration Determination Ethanol Precipitation of Plasmid DNA Sequencing Reaction Experiment 12 Purification of Extension Reaction Products Sequencing Gel Demonstration Experiment 13 Analysis of Sequencing Data Verification of Insert Sequence Experiment 14 Gene Expression Transformation into Expression Host Experiment 15 Induction of LTB Gene Expression Part 2 Protein Chemistry Experiment 16 SDS-PAGE of Induction Time Course Transfer of Protein to Membrane for Western Blot Experiment 17 Visualization of Western Blot Experiment 18 Large Scale Culture Preparation Experiment 19 Isolation of LTB by Affinity Chromatography Experiment 20 SDS-PAGE of Column Fractions Immunoblot to verify Presence of LTB Experiment 21 Protein Concentration Protein Crystallization Experiment 22 Setting up an ELISA Microtiter Plate Experiment 23 ELISA of a Panel of Ganglioside Ligands Experiment 24 Protein Structure Determination: X-ray Diffraction Techniques Experiment 25 Characterization of a Protein Crystal Experiment 26 Primer Design

  • Immunoinformatics

    John Wiley & Sons Inc Immunoinformatics

    Book SynopsisThe astounding diversity of the immune system and the complexity of its regulatory pathways makes immunology a combinatorial science. Computational analysis has therefore become an essential element of immunology research and this has led to the creation of the emerging field of immunoinformatics. This book is the first to feature thorough coverage of this new field. Immunoinformatics facilitates the understanding of immune function by modelling the interactions among immunological components. Biological research provides ever deeper insights into the complexity of living organisms while computer science provides an effective means to store and analyse large volumes of complex data. Combining the two fields increases the efficiency of biological research and offers the potential for major advances in the study of biological systems.
