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 Mitonuclear Ecology written by Geoffrey E. Hill and published by Oxford University Press, USA. This book was released on 2019-04-30 with total page 315 pages. Available in PDF, EPUB and Kindle. Book excerpt: This novel text provides a concise synthesis of how the interactions between mitochondrial and nuclear genes have played a major role in shaping the ecology and evolution of eukaryotes. The foundation for this new focus on mitonuclear interactions originated from research in biochemistry and cell biology laboratories, although the broader ecological and evolutionary implications have yet to be fully explored. The imperative for mitonuclear coadaptation is proposed to be a major selective force in the evolution of sexual reproduction and two mating types in eukaryotes, in the formation of species, in the evolution of ornaments and sexual selection, in the process of adaptation, and in the evolution of senescence. The book highlights the importance of mitonuclear coadaptation to the evolution of complex life and champions mitonuclear ecology as an important subdiscipline in ecology and evolution.
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.

The major aim of this book is to give insight on light emission studies in plant and bacteria in terms of its physiological, biophysical, and biochemical relevance. The book is divided into six parts. Part I serves as an introduction and at the same time a historical review and development of different concepts of the emission phenomena. Part II tackles the relationship of light emission to the various photosynthetic reactions. Part III discusses the concept of bioluminescence, with a focus on bacteria and dinoflagellates. Part IV is a description of the light emission from bacteriorhodopsin and rhodopsin. Part V discusses the special light emission characteristics and their relationship to specialized pigment systems found in different bacteria and plant groups. It also reviews the fluorescence properties of photosynthetic bacteria. Lastly, Part VI basically shows the practical applications of light emission from algae as well as higher plants. This book contains not only relevant information about theories and concepts, but also experiments. Thus, it is a recommended reference to researchers and students alike in the field of cell biology, microbiology, plant physiology, biochemistry, biophysics, and agriculture.

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 Fertilization in Protozoa and Metazoan Animals written by Juan J. Tarin and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 329 pages. Available in PDF, EPUB and Kindle. Book excerpt: Reproduction is the origination of new organisms from pre-existing ones. Among more than 35 separated forms of reproduction including several types of gamogony, parthenogenesis, agamogenesis, fission and division, and plas motomy, the bisexual mode of reproduction via fertilization provides genetic variability that allows species to adapt quickly to competitive and constantly changing environments. Several excellent reviews and books have been written in the past to analyse the mechanisms of fertilization in different eukaryotic species. During the last few years, however, renewed attention has been paid to examining the process of oocyte fertilization at the cellular/molecular level not only within a single species/group but also through different phylogenetic lineages. As a result of this effort, knowledge of the molecular pathways used by oocytes and spermatozoa at fertilization has increased, but still many ques tions remain to be answered. Being aware of the necessity of providing an inte grated view of the process of fertilization, this book has been entirely devoted to reviewing the process of oocyte fertilization at the cellular/molecular level in two different and separated groups of eukaryotic organisms: protozoa and metazoan animals. The book is organized into six sections dealing with oocyte fertilization in protozoa, invertebrates, teleost fishes, amphibians, birds and mammals. These sections are followed by a summary/concluding chapter that provides a com parative overview of the process of fertilization in these groups of eukaryotes.

Download or read book Signaling Mechanisms in Protozoa and Invertebrates written by G. Csaba and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 226 pages. Available in PDF, EPUB and Kindle. Book excerpt: Comparative endocrinology helps to find the roots of homeostatic regulation in organisms. In this context, many years ago a series of experiments were done, which demonstrated the hormonal regula tion also on the invertebrate level. The mechanisms are partly similar, partly different, from those found in vertebrates. The new receptor era of mammalian endocrinology stimulated research on invertebrate hormone receptors, and sophisticated methods are applied also to determine hormones. The experiments demonstrated the existence and even similar function of these structures and signaling molecules. However, data on hormones and receptors at the lowest level of metazoan life and the highest level of protozoan life were not at our disposal. About two decades ago, first observations on the presence of hormone receptors reacting to vertebrate hormones in protozoa were made. Since the early 1980s we know that hormone-like molecules similar to those of higher vertebrates are present also in unicellular organisms. The presence of some second messengers in Tetrahymena was recognized. Since then, the research has been extended and many structures - previously believed to be solely vertebrate characteristics, such as opiate receptors, similar to mammalian ones - were found in unicellular organisms. These observations justified the assumption of a complete endocrine system at protozoan level, where - considering the unicellularit- this seemed to be not required. However, it became clear that the roots of endocrine communication date back at least 2 billion years.

Book excerpt: Biology of Fertilization, Volume 1: Model Systems and Oogenesis is the first in a three-volume series that gathers various lines of research about reproduction in general and fertilization in particular. Knowledge about cell biology, immunobiology, biochemistry, biophysics, and molecular genetics has progressed significantly beyond our understanding of some aspects of fertilization. Components of these constitute ""model systems."" The present volume includes reviews of such systems, some relatively simple model systems in lower organisms, sex-determining mechanisms, and oogenesis. The book contains 12 chapters organized into two sections. Section I includes studies on evolution, reproductive success, and immortality of the germ line; the structures and mechanisms involved in fertilization problems; and fertilization in Paramecium. Section II on oogenesis includes studies on gamete differentiation; sex-determining role of the H-Y antigen in mammals and non-mammals; the mechanism of starfish oocyte maturation; meiotic arrest in animal oocytes; and the mitotic and meiotic aspects of the mammalian germ cell life cycle.
