This book will be of value on a multitude of levels: from a general reference text to a source of research ideas. It will appeal to a wide spectrum of readers in a large number of disciplines, but will be particularly useful to cell biologists, microbiologists, protozoologists, and mycologists interested in the study of cellular communication.
Download or read book Parasitology and Microbiology Research written by Gilberto Antonio Bastidas Pacheco and published by BoD – Books on Demand. This book was released on 2020-06-17 with total page 376 pages. Available in PDF, EPUB and Kindle. Book excerpt: The study of both unicellular and multicellular living beings and the diseases they produce from a biological point of view requires constant review of their relationship with their host and environment, given their indisputable sanitary importance. In this sense, in parasitology and microbiology, updated and concise information on life cycle, taxonomic classification, clinical manifestations, diagnosis, treatment, epidemiological behavior, and control measures is of vital importance. This is what we pursue with this book. The approach to parasitology and microbiology and the research that is carried out on it is unquestionable because the associations between life forms have been present from the very beginning of life.Research in parasitology and microbiology is necessary and indispensable for controlling diseases that affect much of the world with serious economic and social consequences. The challenge is to promote research to keep these diseases at bay. This book shows what has been done up to now and what can be done in the future to combat infectious diseases.

Download or read book The Sex Imperative written by Kenneth E. Maxwell and published by Springer. This book was released on 2013-11-11 with total page 319 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The sex imperative - the irresistible impulse to engage in sexual relations - has enabled animals to share their genes and evolve. Maxwell traces the progress of sex from the simple sharing of genes between cells to the elaborate courtship rituals that developed so sperm could merge with egg. In the effort to join sperm and egg, species have developed some astounding and unusual sexual adaptations. As Maxwell vividly describes the sex lives of various creatures, he attests to the resiliency and amazing adaptability of life to its everchanging environment. By focusing on the diversity of animal sexual relationships, Maxwell enables us to question the very basis of sexuality: What is sex? Why did it evolve? How does sexuality and survival shape the social behavior of animals and humans? The sex imperative is indeed the driving force behind Darwin's theory of random variation and natural selection, better known as "survival of the fittest." Maxwell goes so far as to investigate our latest accomplishment in the science of begetting offspring: genetic engineering." "This awe-inspiring and unique work celebrates the power and wonder of life and sexuality of all creatures - including humans. After reading this engrossing and illuminating work, no one will ever think of evolution in the same way."--Jacket
Download or read book Plant Microbe Interactions written by Gary Stacey and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 328 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Molecular Cloning of Hormone Genes written by Joel F. Habener and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 451 pages. Available in PDF, EPUB and Kindle. Book excerpt: The peptide hormones are small proteins that regulate cellular metabolism through their specific interactions with tissues of the endocrine, nervous, and immune systems, as well as in embry onic development. During the past ten years, refinements in the techniques of recombinant DNA technology have resulted in the cloning of genes encoding approximately 50 different hormonal and regulatory peptides, including those in which the peptides themselves and the mRNAs encoding the peptides are present in only trace amounts in the tissues of origin. In addition to provid ing the coding sequences of recognized hormonal and regulatory peptides, gene sequencing has uncovered new bioactive peptides encoded in the precursor pro hormones that are then liberated along with the hormonal peptides during cellular cleavages of the precursors. The encoding of multiple peptides in a single mono cistronic mRNA appears to be a genetic mechanism for the gener ation of biologic diversification without requiring amplification of gene sequences. Two of the objectives in the assembly of this book are to pre sent, in one volume, the known primary structures of the genes encoding several of the polypeptide hormones and related regulatory peptides, and to provide an account of the various ap proaches that have been used to identify and select the cloned genes encoding these polypeptides. The contents of the two in troductory chapters are intended to provide the reader with a brief background of the approaches to gene cloning and the struc ture and expression of hormone-encoding genes.

Download or read book Cellular Interactions written by H. F. Linskens and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 761 pages. Available in PDF, EPUB and Kindle. Book excerpt: H. F. LINSKENS and J. HESLOP-HARRISON The chapters of this volume deal with intercellular interaction phenomena in plants. Collectively they provide a broad conspectus of a highly active, if greatly fragmented, research field. Certain limitations have been imposed on the subject matter, the most impor tant being the exclusion of long-range interactions within the plant body. It is true that pervasive hormonal control systems cannot readily be demarcated from controls mediated by pheromones or information-carrying molecules with more limited spheres of action, but consideration is given in this volume to the main classes of plant hormones and their functions only incidentally, since these are treated adequately in other volumes of this Encyclopedia series (V - ume 9-11) and in numerous other texts and reviews. Similarly, certain other effects, such as those associated with nutrients and ions, are not considered in any detail. Furthermore, we have excluded intracellular interactions, and also consideration of transport phenomena, which are treated in detail in Vol ume 3 of this Series. Other aspects of inter-cellular interaction, such as cell surface phenomena and implications of lectin-carbohydrate interactions, and plant-virus inter-relationships, are treated in other sections of this Encyclopedia (Volumes 13B and 14B, respectively). In the volume on physiological plant pathology (Volume 4 of this series) special attention has been given to host pathogen interaction. These aspects of our subject will therefore be excluded in the present treatise.
Download or read book Chemical Communication written by William C. Agosta and published by Macmillan. This book was released on 1992 with total page 197 pages. Available in PDF, EPUB and Kindle. Book excerpt: A wounded minnow attempts to rejoin its school and the other minnows scatter in panic; a single beetle finds a pine tree to its liking and soon thousands of beetles swarm that tree and others in the vicinity; a male Syrian golden hamster is drawn along an invisible trail to a burrow where a female hamster awaits him, ready for mating. These animals are responding to received communications, but, as in countless other occurrences in nature, the language is not auditory or visual--it is chemical. Unlike humans, who gather information largely through sight and sound, most living creatures rely heavily on chemical compounds from other organisms for their basic knowledge of the world. Among the various types of these compounds are the chemical signals exchanged between members of the same species that govern social interactions crucial to survival. These signals are called pheromones (from the Greek "pherein"--to carry--and "hormon"--exciting) and they are used to send warnings, establish territorial boundaries, provoke aggression, control sexual behavior, and locate food. In this volume, organic chemist William C. Agosta explores the chemistry of pheromones and the mechanisms by which they orchestrate animal behavior. Professor Agosta details the intricate process of identifying pheromones: first establishing that some behavior in animals is chemically driven, then isolating pheromones and determining the active components within these sometimes highly complex mixtures. He also demonstrates the value of this growing body of knowledge to our understanding of evolution, ecology, human behavior, and agricultural production. The result is a fascinating look at a research area that bringstogether investigators, information, technologies, and procedures from the fields of biology, chemistry, and behavioral science. Chemical Communication spans the entire spectrum of life, from simple organisms, such as water molds and brown algae, to insects, birds, fish, reptiles, mammals, and in a provocative final chapter, human beings. Along the way, Dr. Agosta provides dozens of captivating examples of pheromones in action: certain male red-sided garter snakes, which increase their chances of mating successfully by "impersonating" a female, thus distracting rivals; or the bolas spiders, which capture male moths by hitting them with an adhesive ball on a string after emitting a female moth pheromone that lures the males within range. The book also includes important evidence that pheromones alter physiology as well as behavior. For example, young female mice reach maturity at an accelerated pace after constant exposure to adult male mice.

Download or read book Growth Differentiation and Sexuality written by Friedhelm Meinhardt and published by Springer Science & Business Media. This book was released on 2013-04-17 with total page 432 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mycology, the study of fungi, originated as a subdiscipline of botany and was a descriptive discipline, largely neglected as an experimental science until the early years of this century. A seminal paper by Blakeslee in 1904 provided evidence for self-incompatibility, termed "heterothallism", and stimulated interest in studies related to the control of sexual reproduction in fungi by mating-type specificities. Soon to follow was the demonstration that sexually reproducing fungi exhibit Mendelian inheritance and that it was possible to conduct formal genetic analysis with fungi. The names Burgeff, Kniep and Lindegren are all associated with this early period of fungal genetics research. These studies and the discovery of penicillin by Fleming, who shared a Nobel Prize in 1945, provided further impetus for experimental research with fungi. Thus began a period of interest in mutation induction and analysis of mutants for bio chemical traits. Such fundamental research, conducted largely with Neurospora crassa, led to the one gene: one enzyme hypothesis and to a second Nobel Prize for fungal research awarded to Beadle and Tatum in 1958. Fundamental research in biochemical genetics was extended to other fungi, especially to Saccharomyces cerevisiae, and by the mid-1960s fungal systems were much favored for studies in eukaryotic molecular biology and were soon able to compete with bacterial systems in the molecular arena.

Download or read book Methods in Chemical Ecology Volume 2 written by Kenneth F. Haynes and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 422 pages. Available in PDF, EPUB and Kindle. Book excerpt: Identification of chemicals that affect the naturally occurring interactions be tween organisms requires sophisticated chemical techniques, such as those docu mented in volume 1, in combination with effective bioassays. Without an effective bioassay, the identification becomes akin to looking for a needle in a haystack, but without any idea of what a needle looks like. To a large extent serniochemical identifications must be driven by bioassays. The design of bioassays for use in chemical ecology is governed by the sometimes conflicting objectives of ecological relevance and the need for simplic ity. Bioassay design should be based on observations of the interactions between organisms in their natural context, a theme that appears throughout this volume. As a result, this volume is as much about ecology and behavior as it is about specific methods. It is impossible to design a relevant bioassay, whether it is simple or complex, without understanding at least the fundamentals of how chemical cues or signals mediate the interaction in nature. Thus, the development of bioassay methods must be driven by an understanding of ecology and a knowledge of the natural history of the organisms under study. Given such an understanding, it is often possible to design assays that are both ecologically relevant and easy to perform.
Download or read book Cell Signalling in Prokaryotes and Lower Metazoa written by I. Fairweather and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 416 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cell signalling lies at the heart of many biological processes and currently is the focus of intense research interest. In multicellular organisms, it is central to how different types of cell communicate with each other and how they detect and respond to extracellular signals. Intercellular communication is vital to single-celled organisms as well, allowing them to respond to environmental cues and signals. To date, much of the understanding of signalling mechanisms has come from research on specific cell types (eg mouse lymphocyte and cardiomyocyte) or on organisms in which communication systems such as nervous and endocrine systems are well established. This volume therefore aims to 'fill the gap' by concentrating on 'simple organisms' where the elements of those signalling systems first evolved. Many of the groups covered contain important pathogens or parasites, and the potential for manipulating signalling pathways for therapeutic intervention will be highlighted.
