Download or read book Invertebrate Models of Natural and Drug Sensitive Reward written by Robert Huber and published by Frontiers Media SA. This book was released on 2019-10-17 with total page 172 pages. Available in PDF, EPUB and Kindle. Book excerpt: The rewarding properties of drugs depend on their capacity to activate appetitive motivational states. Because the mechanisms underlying natural reward are an important life-sustaining process and strongly conserved throughout metazoan evolution, invertebrate models provide a powerful complement to the mammalian systems traditionally used in addiction research. A wide range of organizational complexity, combined with genetically manipulable, and relatively simple, accessible nervous systems, make invertebrates excellent models in which to explore general addiction principles. These include the role of natural reward systems in learning, the basic biological mechanisms of drug addiction, and the long-term effects of early drug exposure. The contributions to this e-book illustrate the current state of invertebrate addiction research. The chapters show that the reward circuits of invertebrate taxa are surprisingly sensitive to human drugs of abuse. Employing learning paradigms typically used in vertebrate studies (viz., conditioned place preference and operant, self-administration paradigms), invertebrates are shown to exhibit aspects of the addiction cycle from activational effects of common psychostimulants, sensitization with repeated application, to extinction, withdrawal, and reinstatement. This highlights the value of the comparative approach for both exploring conserved mechanisms underlying drug addiction and the utility of invertebrate models in seeking potential solutions.
Download or read book Pheromone Communication in Moths written by Jeremy D. Allison and published by Univ of California Press. This book was released on 2016-10-25 with total page 411 pages. Available in PDF, EPUB and Kindle. Book excerpt: Common among moths is a mate-finding system in which females emit a pheromone that induces males to fly upwind along the pheromone plume. Since the chemical pheromone of the domesticated silk moth was identified in 1959, a steady increase in the number of moth species whose pheromone attractants have been identified now results in a rich base for review and synthesis. Pheromone Communication in Moths summarizes moth pheromone biology, covering the chemical structures used by the various lineages, signal production and perception, the genetic control of moth pheromone traits, interactions of pheromones with host-plant volatiles, pheromone dispersal and orientation, male pheromones and courtship, and the evolutionary forces that have likely shaped pheromone signals and their role in sexual selection. Also included are chapters on practical applications in the control and monitoring of pest species as well as case studies that address pheromone systems in a number of species and groups of closely allied species. Pheromone Communication in Moths is an invaluable resource for entomologists, chemical ecologists, pest-management scientists, and professionals who study pheromone communication and pest management.

Download or read book Novel aspects of the biology of Chrysomelidae written by Pierre H. Jolivet and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 583 pages. Available in PDF, EPUB and Kindle. Book excerpt: Chrysomelidae, along with Curculionidae and Bruchidae, are the most important phytophagous Coleoptera. At least 37,000 species of leaf beetles belonging to 19 subfamilies have now been described, and more probably remain to be discovered, especially in the tropics. Many species are familiar agricultural pests. The Colorado potato beetle, the cereal beetle, flea beetle and the corn root worms are but a few of the well known pests. Because of the economic importance and biological diversity, chrysomelids are an important taxonomic group for scientific inquiry. This book is divided into eight parts, entitled palaeontology, larvae and larval biology, trophic selection, genetics and evolution defence mechanisms, anatomy and reproduction, pathogens and natural enemies, and general studies in biology. The biologies of agricultural and forestry pests, Leptinotarsa, Plagiodera, Entomoscelis, Paropsis, Mecistomela and Aspidomorpha are dealt with in detail. Others, such as Timarcha and those in the poorly known Megalopodinae, are covered in Part VIII. In this volume the American, European, Asian and Australian fauna occupy the greatest part. This volume, together with Biology of Chrysomelidae (1988), provides a comprehensive coverage and helps to complete the picture of chrysomelid biology.

Download or read book Glossary of Biotechnology Terms Fourth Edition written by Kimball Nill and published by CRC Press. This book was released on 2005-11-16 with total page 413 pages. Available in PDF, EPUB and Kindle. Book excerpt: Even if you studied biotechnology in school, if you haven't stayed current, it's not likely you'll be able to speak the same language as today's biotech scientists. The same is even truer for nanotechnology where everything gets smaller and smaller, except the terminology required to navigate it. In the Glossary of Biotechnology and Nanobiotechnology Terms, Fourth Edition, Kimball Nill continues to improve upon the reference that for over a decade has helped thousands of professionals, including scientists, attorneys, government workers, lobbyists, venture capitalists, and university tech transfer staff, to communicate successfully with those working on the cutting edge of modern science. Now in its fourth edition, Nill has taken the much appreciated step of adding nanotechnology to his glossary. Just by casually perusing the Glossary of Biotechnology and Nanobiotechnology Terms, Fourth Edition you will learn a number of enlightening facts. Even those in related sciences will be surprised to discover what the language unveils. The Glossary of Biotechnology and Nanobiotechnology Terms, Fourth Edition is a handy reference designed for people with little or no training in the biological and chemical sciences, as well as scientists communicating from other disciplines. Unlike other glossaries, this one is both informative and completely accessible. Instead of looking up one term to end up mired in equally difficult terminology, this intelligently designed volume follows what the author refers to as a Reference Chain that steadily leads you to simpler more common terminology, down to a level that anyone with a high school education will be able to understand. The definitions are written utilizing words that enable you to conceptualize the idea embodied in the term, with explanations based on analogy whenever possible. Consider this example: Suppose you just received a funding request, a faculty memo, or patent concern that refers to A-DNA, which happens to be the first definition in the Glossary. A-DNA A particular right-handed helical form of DNA (possessing 11 base pairs per turn), which is the form that DNA molecules exist in when they are partially dehydrated. A-form DNA is found in fibers at 75% relative humidity and requires the presence of sodium, potassium, or cesium as the counterion. Instead of lying flat, the bases are tilted with respect to the helical axis, and there are more base pairs per turn. The A-form is biologically interesting because it is probably very close to the conformation adopted by DNA-RNA hybrids or by RNA-RNA double-stranded regions. The reason is that the presence of the 2'2 hydroxyl group prevents RNA from lying in the B-form. See also B-DNA, DNA-RNA HYBRID, DEOXYRIBONUCLEIC ACID (DNA), BASE PAIR (bp) But then after looking at the above definition, you wonder what exactly is a DNA-RNA Hybrid? DNA-RNA Hybrid A double helix that consists of one chain of DNA hydrogen-bonded to a chain of RNA by means of complementary base pairs. See also HYBRIDIZATION (MOLECULAR GENETICS), HYBRIDIZATION (PLANT GENETICS), DOUBLE HELIX ...however while you've often heard mention of a double helix, you were never quite sure what that meant.... Double Helix The natural coiled conformation of two complementary, antiparallel DNA chains. This structure was first put forward by Watson and Crick in 1953. See also DEOXYRIBONUCLEIC ACID (DNA) And that might brings you to ask, Do you really actually know what DNA is? Deoxyribonucleic Acid (DNA) Discovered by Frederick Miescher in 1869, it is the chemical basis for genes. The chemical building blocks (molecules) of which genes (i.e., paired nucleotide units that code for a protein to be produced by a cell's machinery, such as its ribosomes) are constructed. Every inherited characteristic has its origin somewhere in the code of the organism's complement of DNA. The code is made up of subunits called nucleic acids. The sequence of the four nucleic acids is interpreted by certain molecular systems in order to produce the proteins required by an organism. The structure of the DNA molecule was elucidated in 1953.... The Glossary of Biotechnology and Nanobiotechnology Terms, Fourth Edition is packed with over 400 pages of exceptionally well-organized and cross-referenced terminology, making it an essential reference for anyone working directly or indirectly with those pioneering the frontiers of modern biology.
