Abstract

The field of sensory science has grown exponentially since the publication of the first edition of Sensory Evaluation of Food. Fifteen years ago, the journal Food Quality and Preference was fairly new. Now it holds an eminent position as a venue for research on sensory test methods (among many other topics).  Knowledge of the intricate cellular processes in chemoreception, as well as their genetic basis has undergone nothing less than a revolution, culminating in the award of the Nobel Prize to Buck and Axel in 2004 for their discovery of the olfactory receptor gene super family. Advances in statistical methodology have accelerated as well. Sensometrics meetings are now vigorous and well-attended annual events. And yet, some things stay the same. Sensory testing will always involve human participants. But humans are tough measuring instruments to work with. They come with varying degrees of acumen, training, experiences, differing genetic equipment, sensory capabilities, and of course, different preferences. Human foibles and their associated error variance will continue to place a limitation on sensory tests and actionable results. Although methods continue to evolve, appreciation of the core principles of the field is the key to effective application of sensory test methods. This book has been expanded to reflect the advances in methodologies, theory, and analysis that have transpired in the last 15 years. The chapters are now divided into numbered subsections. This may be of assistance to educators who may wish to assign only certain critical sections to beginning students. In some of the opening sections instructors will find suggestions about which sections are key for fundamental understanding of that topic or method. In many chapters we have gone out on a limb and specified a “recommended procedure.” In cases where there are multiple options for procedure or analysis, we usually chose a simple solution over one that is more complex. This text attempts to be comprehensive, yet understandable to all students at the university level. All the major sensory test methods are illustrated and discussed, including discrimination, descriptive, and affective tests. Some chapters are devoted to special topics, such as thresholds, time-intensity methods, similarity testing, color, texture, sensory quality control, qualitative research methods, consumer test methods and questionnaires, shelf life testing, an introduction to multivariate statistical techniques, and strategic sensory research. The statistical appendix provides basic instruction in the common statistical analyses for sensory evaluation with worked examples. Harry T. Lawless is Professor of Food Science at Cornell University where he teaches sensory evaluation. He has 35 years of experience in chemosensory research and psychophysics. He spent five years in consumer testing in industry, and serves as a consultant to various food and consumer products companies on sensory test methods. Hildegarde Heymann is Professor of Viticulture and Enology at the University of California at Davis where she teaches sensory evaluation of wine and sensometrics. She spent nearly 17 years at the University of Missouri as a professor of sensory science.

Abstract

This book presents a significant and up-to-date review of various recognition receptors, their immobilization, and an overview of surface characterization techniques. Distinguished scientists from key institutions worldwide have contributed chapters that provide a deep analysis of their particular subjects; at the same time, each topic is framed within the context of this integrated approach. This work explores comprehensively the field of recognition receptors, presenting a thorough review of the subject and effective integration of these receptors on sensor surfaces in order to appropriately convey state-of the-art fundamentals and applications of the most innovative approaches. The book consists of four parts: The first part comprises three chapters, which are devoted to the introduction of biomolecular recognition, surface sensitization and recognition receptors immobilization, as well as containing an overview of the analytical tools that can be used for surface characterization. The second part describes the different natural recognition receptors (enzymes, antibodies, cells, tissues, plant tissues, peptides, bacteriophages and photosynthetic proteins) currently used in the field of biosensors and microarrays. It covers the theory behind each technique and delivers a detailed state-of-the-art review for each new technology. The third part covers the recognition receptors that can be prepared and tailored by man to mimic natural molecules used in biosensors and microarrays. It describes in detail the use of engineered antibodies, carbohydrates, nucleic acids, oligonucleotides, aptamers, genetically engineered cells, genetically engineered proteins, phage display, molecularly imprinted polymers, and biomemetic materials as recognition elements. The fourth part contains one chapter that briefly covers the kinetics and thermodynamics of association/dissociation of analytes to the recognition receptors on sensor surfaces. Students and researchers who need a solid foundation or reference, and practitioners interested in discovering more about what is state-of-the-art in the field of recognition receptors will find this book invaluable. This book is written for academics, from undergraduate and postgraduate students upward, working in areas related to chemical/bio-sensors. It would be an important reference for, but not limited to, professionals working in varied fields including biology, biotechnology, biochemistry, analytical chemistry, biomedicine, physical chemistry, microsystem engineering, nanotechnology, veterinary, food QA, bioterrorism and security, as well as health surveillance. The book has more than 150 illustrations and figures to help explain and clarify the ideas presented.

Abstract

Upon completion of the human genome project over 800 G protein-coupled receptor 1 (GPCR) genes, subdivided into five categories, were identified. These receptors sense a diverse array of stimuli, including peptides, ions, lipid analogues, light and odour, in a discriminating fashion. Subsequently, they transduce a signal from the ligand–receptor complex into numerous cellular responses. The importance of GPCRs is further reflected in the fact that they constitute the most common target for therapeutic drugs across a 2 wide range of human disorders. Phylogenetic analysis of GPCRs produced the GRAFS classification system, which subdivides GPCRs into five discrete families: glutamate, rhodopsin, adhesion, frizzled/taste2 and secretin receptors. The adhesion-GPCR family 2 can be further subdivided into eight groups. The field of adhesion-GPCR biology has indeed become large enough to require a volume dedicated solely to this field. The contributors to this book have made a courageous effort to address the key concepts of adhesion-GPCR biology, including the evolution and biochemistry of adhesion-GPCRs; there are extensive discussions on the functional nature of these receptors during development, the immune response and tumourgenesis. Finally, there are chapters dedicated to adhesion-GPCR signalling, an area of intense investigation.

Abstract

The poor prognosis and high mortality for cancer patients are majorly ascribed to tumor metastasis, one of the most complicated pathological processes. Elucidation of molecular mechanisms for metastasis is essential for management and prevention of this lethal condition. In the book to be published, we take comprehensive review in regard with the signal mechanisms responsible for triggering a series of phenotypical changes of primary tumor which may lead to final colonization of the tumor in a second home. Specifically, the initial stage of tumor metastasis will be highlighted. The complex tumor microenvironment accumulate a lot of growth factors, inflammatory cytokines and extracellular matrix which may turn into a group of potent metastatic factors. An integrated and sustained signaling induced by these metastatic factors may trigger EMT, migration and invasion of primary tumor into surround tissue. Blokcade of these signal pathways is the most effective approach for prevention of tumor metastasis. A lot of clinical trials are under way for this purpose and the outcome are promising. The expert reviews compiled in this book may encourage the researcher in this exciting field for future study.
