Chemokines: Methods and Protocols (Methods in Molecular Biology #1013)

by Eroboghene E. Ubogu Astrid E. Cardona

Chemokines constitute a large family of structurally similar cytokines that contain a signature of conserved cysteine residues joined by disulfide bridges. Binding of chemokines to specific G protein-coupled receptors followed by downstream signaling defines their biological function. Initially, chemoattraction was the key function linked to chemokines/chemokine receptors; however, in recent years, it has become clear that chemokine ligand-receptor interactions can also modulate cellular activation, survival, and proliferation, among other functions in homeostatic and diseased states. Importantly, major advances in our understanding of chemokine biology have led to chemokine receptors becoming specific therapeutic targets with great potential. In Chemokines: Methods and Protocols, expert researchers provide practical information regarding experimental models and state of the art protocols used to delineate chemokine/chemokine receptor function and their applications in health and disease. 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. Practical and easy to use, Chemokines: Methods and Protocols aims to reveal key protocols of functional and descriptive chemokine ligand/receptor assays that will be of practical significance to graduate students, post-doctoral fellows, trainees, and researchers in academia and industry.

Chemometrics: Chemical and Sensory Data

by David R. Burgard

Ranging from elegantly simple to extremely complex, a wide variety of flavors and fragrances stimulate our senses. It is difficult to understand the myriad sensory interactions involved because of the sheer complexity of their chemical composition. The aim of this text is to describe the use of chemometric techniques for understanding these complex systems and to serve as a practical guide to the acquisition, organization and reduction of chemical and sensory data. It explains chemical, sensory and multivariate analysis tools and their application. Pertinent concepts are discussed in-depth and are sufficiently illustrated with enough original data in complementary tables and figures to provide the basis for the execution of complex studies. The book emphasizes techniques that have been proven to work rather than those that "should" work from a theoretical standpoint. The book focuses on the acquisition of quality data and the subsequent interpretation of data rather than numerical computations used in data analysis. Chemometrics: Chemical and Sensory Data is an excellent resource for students and newcomers to flavor and fragrance research, as well as for experienced workers and product development managers.

Chemoprophylaxis and Virus Infections of the Respiratory Tract: Volume 2

by J.S. Oxford

Originally, it was our intention to produce a single-volume book covering all aspects and approaches to the problem of specific inhibitors of respiratory viruses. However, as the work progressed it became obvious that certain chapters, because of the research interests of the authors, concentrated particularly on influenza viruses. It seemed logical therefore, to divide the book into two volumes, the first emphasizing influenza and the second concentrating on other viruses as well as discussing important general aspects of drug screening and clinical testing, although the second volume does have some chapters which deal mainly with influenza.

Chemosensory Systems in Mammals, Fishes, and Insects (Results and Problems in Cell Differentiation #47)

by Wolfgang Meyerhof Sigrun Korsching

The sense of smell has varied roles in locating food, detecting predators, navigating, and communicating social information, whereas the taste system is focused on decision-making in food intake. The last decade has witnessed massive advances in understanding the molecular logic of chemosensory information processing, and the results for taste sensation were found to differ in interesting ways from those for smell sensation. The 12 chapters of this book cover the current knowledge about the chemosensory systems in mammalian, fish and insect models. The advantages of the different model systems are emphasized. The genomic characteristics and evolution of olfactory and gustatory receptor gene families are analyzed, rules for odorant receptor gene choice and axonal projection of the corresponding receptor neurons are discussed, and the similarities and dissimilarities of pheromone vs. odorant sensing are examined as well as the molecular logic of mammalian sweet taste, bitter taste, and fat perception. Olfactory-guided and taste-guided behaviors are discussed, with a particular emphasis on the insect system.

The Chemostat: Mathematical Theory of Microorganism Cultures

by Alain Rapaport Claude Lobry Jérôme Harmand Tewfik Sari

Invented by J. Monod, and independently by A. Novick and L. Szilard, in 1950, the chemostat is both a micro-organism culturing device and an abstracted ecosystem managed by a controlled nutrient flow. This book studies mathematical models of single species growth as well as competition models of multiple species by integrating recent work in theoretical ecology and population dynamics. Through a modeling approach, the hypotheses and conclusions drawn from the main mathematical results are analyzed and interpreted from a critical perspective. A large emphasis is placed on numerical simulations of which prudent use is advocated. The Chemostat is aimed at readers possessing degree-level mathematical knowledge and includes a detailed appendix of differential equations relating to specific notions and results used throughout this book.
