Molecular biology, particularly molecular genetics, is among the newest and most powerful approach in modern photosynthesis research. Development of molecular biology techniques has provided new methods to solve old problems in many biological disciplines. Molecular biology has its greatest potential for contribution when applied in combination with other disciplines, to focus not just on genes and molecules, but on the complex interaction between them and the biochemical pathways in the whole organism. Photosynthesis is surely the best studied research area in plant biology, making this field the foremost candidate for successfully employing molecular genetic techniques. Already, the success of molecular biology in photosynthesis has been nothing short of spectacular. Work performed over the last few years, much of which is sum marized in this volume, stands in evidence. Techniques such as site-specific mutagenesis have helped us in examining the roles of individual protein domains in the function of multiunit complexes such as the enzyme ribulose-l,5-bisphos phate carboxylase/oxygenase (RUBISCO) and the oxygen evolving photo system (the photosystem II). The techniques of molecular biology have been very important in advancing the state of knowledge of the reaction center from the photosynthetic bacteria whose structure has been elegantly deduced by H. Michel and 1. Deisenhofer from the X-ray studies of its crystals."
Part of a review series that looks at trends in modern biology. This book covers aspects of bioprocessing and biotransformation, where knowledge, methods and expertise are required from chemistry, biochemistry, microbiology, genetics, chemical engineering and computer science.
Well designed, constructed and maintained reinforced or prestressed concrete structures are generally very durable. In aggressive environments though, corrosion of steel can be a significant problem and structures such as bridges, industrial buildings and those subjected to marine conditions can be particularly at risk. Over the last decade there has been fast growing interest in reinforcing concrete with fibre reinforced plastic materials which cannot rust or deteriorate like steel. This proceedings of the Second International RILEM Symposium on the subject, held in Ghent, August 1995, deals with a wide range of non-metallic materials and opens up possibilities of lighter, more durable structures. The contributions by leading international researchers and design engineers are divided into parts covering material development and properties, bond behaviour of FRP elements, structural behaviour of reinforced and prestressed concrete members, rehabilitation and strengthening, and design methods and applications. This complete overview of knowledge on the subject will provide an essential update for structural engineers, concrete specialists and researchers into materials and structures.
Recent research, which Bone- Metabolic Function and Modulators expands on, has added new support to the idea that bone not only serves as a support system, but also functions as an integrating organ, with a significant regulatory role for lipid and energy metabolism. Links between physical activity and the skeleton are also becoming increasingly clear. This fully illustrated volume contains up-to-date information on the metabolic role of the skeleton and what this can mean for the treatment of metabolic as well as skeletal and auditory diseases. Bone- Metabolic Function and Modulators is of particular interest to clinician scientists, clinical and basic bone researchers, orthopedists, endocrinologists, internists, dentists, nurse practitioners, medical and dental residents and physiotherapists as well as students of the musculoskeletal system. Bone- Metabolic Function and Modulators is the seventh volume in the series Topics in Bone Biology, edited by Felix Bronner and Mary C. Farach-Carson.

The study of phase transitions is among the most fascinating fields in physics. Originally limited to transition phenomena in equilibrium systems, this field has outgrown its classical confines during the last two decades. The behavior of far from equilibrium systems has received more and more attention and has been an extremely active and productive subject of research for physicists, chemists and biologists. Their studies have brought about a more unified vision of the laws which govern self-organization processes of physico-chemical and biological sys tems. A major achievement has been the extension of the notion of phase transi tion to instabilities which occur only in open nonlinear systems. The notion of phase transition has been proven fruitful in apphcation to nonequilibrium ins- bihties known for about eight decades, like certain hydrodynamic instabilities, as well as in the case of the more recently discovered instabilities in quantum optical systems such as the laser, in chemical systems such as the Belousov-Zhabotinskii reaction and in biological systems. Even outside the realm of natural sciences, this notion is now used in economics and sociology. In this monograph we show that the notion of phase transition can be extend ed even further. It apphes also to a new class of transition phenomena which occur only in nonequilibrium systems subjected to a randomly fluctuating en vironment."
"Modern Solid State Fermentation: Theory and Practice" covers state-of-the-art studies in the field of solid state fermentation (SSF). In terms of different characteristics of microbial metabolites, this book catalogs SSF into two main parts: anaerobic and aerobic SSF. Based on the principles of porous media and strategies of process control and scale-up, which are introduced in the book, it not only presents a well-founded explanation of essence of solid state fermentation, but also their influence on microbial physiology. In addition, due to the rapid development of this field in recent years, inert support solid state fermentation is also examined in detail. At last, the modern solid state fermentation technology platform is proposed, which will be used in solid biomass bioconversion. This book is intended for biochemists, biotechnologists and process engineers, as well as researchers interested in SSF. Dr. Hongzhang Chen is a Professor at Institute of Process Engineering, Chinese Academy of Sciences, Beijing, China.
The International Society of Oxygen Transport to Tissue (ISOTT) was founded in 1973 to provide a forum for bioengineers, basic scientists, physiologists, and physicians to discuss new data, original theories, new interpretations of old data, and new technologies for the measurement of oxygen. At each annual meeting all posters are presented orally along with plenary lectures, and all presentations are given in a general session attended by everyone. Each meeting has had a specific focus, ranging from neonatology to physical chemistry to cancer biology. The Society has helped to build many careers, through opportunities to meet leaders in the field, and through awards made to young physicians and scientists. The Society also, through cross fertilization of ideas and scientific comradery, has inspired many breakthroughs in clinical medicine that now benefit mankind. I find myself president of the society after having been a winner of the Melvin Knisely Award for young scientists, in 1991. The 2003 meeting emphasized the role of oxygen and oxygen measurement in tumor growth, metastasis, physiology, and treatment resistance. Additionally, however, completely novel approaches to measurement of tissue oxygen were presented (notably work by Dr. Takahashi) and molecular methods for estimating tissue oxygen were evaluated. Papers discussing other aspects of oxygen measurement and pathophysiology were presented including in vivo ESR spectroscopy (notably including Dr. Swartz and colleagues), exercise physiology, organ transplant outcome (discussed by Dr. Cicco, our 2004 president), circulatory physiology, and cerebral oxygenation (notably including Dr. Chance).
The volumes of this classic series, now referred to simply as "Zechmeister" after its founder, L. Zechmeister, have appeared under the Springer Imprint ever since the series' inauguration in 1938. The volumes contain contributions on various topics related to the origin, distribution, chemistry, synthesis, biochemistry, function or use of various classes of naturally occurring substances ranging from small molecules to biopolymers. Each contribution is written by a recognized authority in his field and provides a comprehensive and up-to-date review of the topic in question. Addressed to biologists, technologists, and chemists alike, the series can be used by the expert as a source of information and literature citations and by the non-expert as a means of orientation in a rapidly developing discipline.
Reviews of Environmental Contamination and Toxicology provides detailed review articles concerned with aspects of chemical contaminants, including pesticides, in the total environment with toxicological considerations and consequences.
This work introduces the concept of reformulation, a relatively new strategy to develop foods with beneficial properties. Food reformulation by definition is the act of re-designing an existing, often popular, processed food product with the primary objective of making it healthier. In recent years the concept of food reformulation has evolved significantly as additional benefits of re-designing food have become apparent. In addition to targeting specific food ingredients that are considered potentially harmful for human health, food reformulation can also be effectively used as a strategy to make foods more nutritious by introducing essential macro- /micro-nutrients or phytochemicals in the diet. Reformulating foods can also improve sustainability by introducing "waste" (and underutilized) ingredients into the food chain. In light of these developments, reformulating existing foods is now considered a realistic and attractive opportunity to provide healthy, nutritious, and sustainable food choices to the consumers and likewise improve public health. Indeed reformulation has now become essential in many cases for redressing the health properties of foods that are popularly consumed and significantly affecting public health. This edited volume covers aspects of food reformulation from various angles, exploring the role of the food industry, academia, and consumers in developing new products. Some of the major themes contributors address include methods of reformulating food products for health, improving the nutritional composition of foods, and challenges to the food industry, including regulation as well as consumer perception of new products. The book presents several case studies to clarify these objectives and illustrate the difficulties encountered in the process of developing a reformulated product. Chapters from experts in the field identify emerging and future trends in food product development, and highlight ways in which these efforts will help with increasing food security, improving nutrition and health, and promoting sustainable production. The editors have designed the book to be useful for both industry professionals and the research community. This interdisciplinary approach incorporates a wide spectrum of food sciences (including composition, engineering, and chemistry) as well as nutrition and public health. Food and nutrition professionals, policy makers, health care and social scientists, and graduate students will also find the information relevant.
Advances in biochemistry, cell biology, genome-wide mutagenesis - coupled with molecular technology, including gene microarray and transgenic and knock-out animals - have been instrumental in understanding the cellular processes and molecular pathways of self-tolerance and autoimmune diseases. The molecular definition of these pathways and processes has led to novel treatments for certain auto-immune diseases that are based on the pathogenesis of diseases rather than on broad-spectrum immunosuppression. This book reviews many of these current developments and proposes future novel approaches for understanding the pathogenesis of auto-immune diseases and designing novel therapy. This book covers three major areas of auto-immunity: the basic mechanisms of immunological tolerance, pathogenesis of auto-immune diseases, and some novel therapies. This book should be useful for immunologists, molecular biologists, rheumatologists, and clinical scientists.
Time-resolved fluorescence spectroscopy is widely used as a research tool in bioch- istry and biophysics. These uses of fluorescence have resulted in extensive knowledge of the structure and dynamics of biological macromolecules. This information has been gained by studies of phenomena that affect the excited state, such as the local environment, quenching processes, and energy transfer. Topics in Fluorescence Spectroscopy, Volume 4: Probe Design and Chemical Sensing reflects a new trend, which is the use of time-resolved fluorescence in analytical and clinical chemistry. These emerging applications of time-resolved fluorescence are the result of continued advances in laser detector and computer technology. For instance, pho- multiplier tubes (PMT) were previously bulky devices. Miniature PMTs are now available, and the performance of simpler detectors is continually improving. There is also considerable effort to develop fluorophores that can be excited with the red/ne- infrared (NIR) output of laser diodes. Using such probes, one can readily imagine small time-resolved fluorometers, even hand-held devices, being used fordoctor's office or home health care.

Recent years have seen tremendous progress in unraveling the molecular basis of different plant-microbe interactions. Knowledge has accumulated on the mecha nisms of the microbial infection of plants, which can lead to either disease or resistance. The mechanisms developed by plants to interact with microbes, whether viruses, bacteria, or fungi, involve events that can lead to symbiotic association or to disease or tumor formation. Cell death caused by pathogen infection has been of great interest for many years because of its association with plant resistance. There appear to be two types of plant cell death associated with pathogen infection, a rapid hypersensitive cell death localized at the site of infection during an incompatible interaction between a resistant plant and an avirulent pathogen, and a slow, normosensitive plant cell death that spreads beyond the site of infection during some compatible interactions involving a susceptible plant and a virulent, necrogenic pathogen. Plants possess a number of defense mechanisms against infection, such as (i) production of phytoalexin, (ii) formation of hydrolases, (iii) accumulation of hydroxyproline-rich glycoprotein and lignin deposition, (iv) production of pathogen-related proteins, (v) produc tion of oligosaccharides, jasmonic acid, and various other phenolic substances, and (vi) production of toxin-metabolizing enzymes. Based on these observations, insertion of a single suitable gene in a particular plant has yielded promising results in imparting resistance against specific infection or disease. It appears that a signal received after microbe infection triggers different signal transduction pathways."
Since the initial establishment of Robert Koch's postulates in the nineteenth century, microbial protein toxins have been recognized as a major factor of bacterial and fungal virulence. An increasing number of proteins produced and secreted by various bacteria, yeasts and plants are extremely toxic and most of them developed remarkably "intelligent" strategies to enter, to penetrate and to finally kill a eukaryotic target cell by modifying or blocking essential cellular components. This book describes the strategies employed by protein toxins to render their pro- and eukaryotic producers a selective growth advantage over competitors. In providing an up-to-date overview on the mode of protein toxin actions, it accommodates biomedically and biologically relevant toxin model systems. As a result, it significantly broadens our perspective on biochemical architecture and molecular ploy behind the lethal principles of pro- and eukaryotic toxins.
This volume discusses protocols that aid in measuring different components in the renin-angiotensin-aldosterone system (RAAS). The book also looks at the methods used to assess angiotensin peptides and discerning the influence of RAAS components on different mammalian diseases. The chapters cover topics such as the use of fluorescent substrate to measure ACE2 activity in the mouse abdominal aorta, blood pressure monitoring using the radio telemetry method, and the analysis of angiotensin metabolism in the kidney using mass spectrometry. 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 tips on troubleshooting and avoiding known pitfalls. Cutting edge and comprehensive, The Renin-Angiotensin-Aldosterone Systems: Methods and Protocols is a valuable resource that provides scientists and researchers with the best approaches to examine RAAS.
Plant-Microbe Interactions, Volume 1 Many plant-microbe interactions have agronomic importance because of either beneficial (e.g., nitrogen fixation or biocontrol) or detrimental (e.g., pathogen esis) effects. Although these systems have been the subjects of scientific re search for many years, recently there has been a tremendous increase in our knowledge of them. The increases in this research have followed a similar general increase in plant science research. Classical plant science research disciplines (e.g., agronomy, breeding, plant physiology, systematics, etc.) have been affected by an increased focus on molecular biology. These new technologies, as well as advances in other areas, have the effect of blurring the traditional borders between research disciplines. Another factor influencing the development of this research is the increased attention given to environmental issues. These concerns have been brought about by debate over the release of genetically modified organisms and the general concern over environmental quality. Thus, research areas focused on plant-microbe interactions are presently in a period of great excitement and growth that shows every sign of continuing far into the future. As in most research areas, the rate of advance and breadth of disciplines involved in the study of plant-microbe interactions make it impossible for the average researcher or student to stay abreast of the primary scientific literature."
The present book collects selected contributions from researchers working in the field of food science, and participating at the second spring school for Food Quality, Safety and Technology, which was held in Botucatu (Sao Paulo, Brazil), from September 24th to 27th, 2012, at the Botucatu Campus of the Universidade Estadual Paulista Julio Mesquita Filho (UNESP). The goal of the conference was to provide a scientific forum covering large areas of agronomy, nutrition, food science and technology, veterinary and other areas related to food technology development. Teachers, professionals, graduate and post-graduate students in Food Science; Food and Agriculture Engineering; Veterinary, Science and Food Technology and related areas were addressed by providing an exchange of knowledge and technologies. The initiative aimed to establish uniform, globally recognized scientific principles on food safety and quality, which could be consistently applied to industry and production sectors and stakeholders, taking into account that effective food control systems are essential to protecting the health and safety of domestic consumers, to guaranteeing the safety and quality of foods entering international trade, and to ensuring that imported foods conform to national requirements."
Following three printings of the First Edition (1978), the publisher has asked for a Second Edition to bring the contents up to date. In doing so the authors aim to show how the newer microscopies are related to the older types with respect to theoretical resolving power (what you pay for) and resolution (what you get). The book is an introduction to students, technicians, technologists, and scientists in biology, medicine, science, and engineering. It should be useful in academic and industrial research, consulting, and forensics; how ever, the book is not intended to be encyclopedic. The authors are greatly indebted to the College of Textiles of North Carolina State University at Raleigh for support from the administration there for typing, word processing, stationery, mailing, drafting diagrams, and general assistance. We personally thank Joann Fish for word process ing, Teresa M. Langley and Grace Parnell for typing services, Mark Bowen for drawing graphs and diagrams, Chuck Gardner for photographic ser vices, Deepak Bhattavahalli for his work with the proofs, and all the other people who have given us their assistance. The authors wish to acknowledge the many valuable suggestions given by Eugene G. Rochow and the significant editorial contributions made by Elizabeth Cook Rochow."
The International Symposium on Prostaglandins and Related Compounds, first held in Vienna 1972, revisited the city after 24 years for the 10TH Symposium. For the many re searchers working in this multi-disciplinary field it was an opportunity to exchange their ex periences and share new data with colleagues from all around the world. This scientific exchange was largely encouraged by the unseasonably cold and rainy weather. For the first time, there was quite a large attendance from the former Communist countries. Eugene Garfield prepared a key note address delivered during the meeting (The Sci entist 1996, 12) reviewing the contribution of the Nobel Laureates U.S. von Euler, l.R. Vane, S.K. Bergstrom, and B.I. Samuelsson, discussing the relevance of the more than 40,000 pa pers in this area published since 1991. Overall, there is still a rapidly growing interest, and in particular a great variety of clinical applications of this family of compounds which were dis cussed in detail during the meeting. Beside the lectures there were 19 workshops covering nearly all the topics of key in terest. All the speakers were invited to prepare a manuscript which has resulted in the volume now in your hands. Special thanks to Dr. Patrick Wong and the new publisher of this series who helped to publish the proceedings in the usual quality and reasonable period of time. Looking forward to seeing all of you again in Florence in 1999, hopefully with much more sun."
Phytochemicals from medicinal plants are receiving ever greater attention in the scientific literature, in medicine, and in the world economy in general. For example, the global value of plant-derived pharmaceuticals will reach $500 billion in the year 2000 in the OECD countries. In the developing countries, over-the-counter remedies and "ethical phytomedicines," which are standardized toxicologically and clinically defined crude drugs, are seen as a promising low cost alternatives in primary health care. The field also has benefited greatly in recent years from the interaction of the study of traditional ethnobotanical knowledge and the application of modem phytochemical analysis and biological activity studies to medicinal plants. The papers on this topic assembled in the present volume were presented at the annual meeting of the Phytochemical Society of North America, held in Mexico City, August 15-19, 1994. This meeting location was chosen at the time of entry of Mexico into the North American Free Trade Agreement as another way to celebrate the closer ties between Mexico, the United States, and Canada. The meeting site was the historic Calinda Geneve Hotel in Mexico City, a most appropriate site to host a group of phytochemists, since it was the address of Russel Marker. Marker lived at the hotel, and his famous papers on steroidal saponins from Dioscorea composita, which launched the birth control pill, bear the address of the hotel."
Antimicrobial peptides have been the subject of intense research in the past decades, and are now considered as an essential part of the defense system in bacteria, plants, animals and humans. This book provides an update on these effector molecules of the innate immune system both for researchers who are already actively involved in the area, and for those with a general interest in the topic. The book starts with an overview of the evolution of cysteine- containing antimicrobial peptides (including defensins), and the role of these peptides in host defense in plants and micro- organisms. The realization that antimicrobial peptides also display functions distinct from their direct antimicrobial action is the focus of the next chapters, and puts these peptides center stage in immunity and wound repair. Further chapters discuss the role of antimicrobial peptides in disease, by providing an overview of mechanisms in bacterial resistance to antimicrobial peptides and a discussion of their role in inflammatory bowel disease, cystic fibrosis lung disease and chronic obstructive pulmonary disease. Finally, the book shows how knowledge of the function of antimicrobial peptides and their regulation can be used to design new therapies for inflammatory and infectious disorders. This is a very important area of research because of the increase in resistance of micro-organisms to conventional antibiotics. Therefore the use of synthetic or recombinant peptides, or agents that stimulate the endogenous production of antimicrobial peptides, provides an attractive alternative for conventional antibiotics.
Investigation of the mechanisms of cellular response to different mechanical stimuli, as well as mechano-electrical feedback (MEF) in the intact heart is one of the main topics in fundamental and clinical cardiology. The present volume of "Mechanosensitivity in Cells and Tissues: Mechanosensitivity of the Heart" c- bines excellent reviews written by worldwide leaders in this ?eld. The 3rd volume is a great addition to this excellent series of books edited by Andre Kamkin and Irina Kiseleva. This volume successfully combines reviews, aimed at academic, physiology and clinical cardiology communities, devoted to mechanosensitivity of the normal and diseased heart at the ion channel, cell, tissue and organ levels. Kamkin and Kiseleva have made signi?cant contributions to the investigation of mechanosentive ion channels in cardiomyocytes and ?broblasts. Their ba- ground, in addition to extensive collaborations helped them to ?nd and consolidate valuable research ?ndings from prominent specialists in the ?eld of cardiac mechanosensitivity. In the last decade, interest in the role of MEF in the heart has increased sign- cantly. MEF within cardiac tissue is a complex phenomenon in which electroph- iological changes are triggered by myocardial stretch. This phenomenon has been studiedintheclinicalcommunityforoveracenturyandmayhavebothpro-rhythmic and arrhythmogenic consequences. While signi?cant advances have been made in understanding of the effects of mechanical forces on cardiac cells, many questions remain regarding the mechanisms whereby mechanical forces are transduced into changes which alter the behavior of various cardiac cells. |
