Book excerpt: Marine Pharmacognosy: Action of Marine Biotoxins at the Cellular Level focuses on the study and utilization of marine drugs. This book discusses the methods of isolation and characterization of bioactive agents, bioassays, microcalorimetry, voltage-clamp techniques, toxin-induced alterations, measurement of muscle contraction, and kinetics of toxin-induced hemolysis. Organized into nine chapters, this book starts with an overview of the use and usefulness of marine bioactive agents as research tools. This text then examines the pharmacological effects of maculotoxin, which are similar to those of tetrodoxin and saritoxin. Other chapters consider the role of choline in general cellular processes. This book discusses as well the rate of hemolysis as a function of prymnesin concentration. The final chapter deals with the features of the prymnesin–membrane interaction. This book is a valuable resource for pharmacologists, bacteriologists, zoologists, physiologists, botanists, and oceanographers. Scientists involved in biological oceanography and comparative physiology will also find this book useful.

The general characteristics of chemoreception at the membrane level using plasmodium as a model organism, as well as the structure and motility of plasmodium, are also included. The third part of the book focuses on genetic analysis of plasmodium development and the discovery of techniques for the genetic manipulation of P. polycephalum. Progress in the genetic analysis of other processes is summarized. The concluding part examines the morphological evolution of the nucleus during the mitotic cycle together with the results from ultracytochemical and radioautographic studies. It also includes a discussion on DNA organization and replication in P. polycephalum. Finally, the synthesis and degradation of RNA in Physarum and the relationship of these biochemical processes to mitotic cycle and differentiation are tackled in the concluding chapter. The book will serve as a frequent, single reference source to brief cell biologists on the primary research on Physarum and Didymium. It will be a good source for graduate students in cell biology, and perhaps in other graduate courses.

Download or read book Cellular Regulation of Secretion and Release written by P. Michael Conn and published by Elsevier. This book was released on 2013-09-24 with total page 612 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cellular Regulation of Secretion and Release is a compilation of papers that deals with the processes in cellular perception of stimuli and the response to them. Part I describes the receptor occupancy and regulation of stimulus through the use of video image intensification techniques. This part also explains a model for the transmembrane regulation of adenylate cyclase that shows the mechanisms that cells use in sensing and responding to extracellular conditions. Part II discusses the early responses of secretory cells including changes in phospholipid metabolism, in electrophysiological events, and in macromolecular carboxymethylation. One paper suggests that protein-carboxyl methylase has a role in neurotransmission and secretion whether as a part of the exocytotic process or just a help to regulate the process. Part III addresses the role in secretion of the subcellular architecture particularly as regards the role of the cytoskeleton in endocrine function or insulin secretion and cytoskeletal proteins. Part IV discusses the synthesis, processing, and storage of secretory products, including the role of signal peptides, their properties, and interactions. Part V addresses the mechanisms and modulation of secretion and release in a study of Leydig cells. One paper concludes that the regulation of release, through dopamine and TRH factors, can have more than one mechanism of action. This book can be useful for cellular microbiologists, bacteriologists, endocrinologists, researchers, and academicians in the biochemistry and in reproductive medicine.

Download or read book Changes in Eukaryotic Gene Expression in Response to Environmental Stress written by Burr Atkinson and published by Elsevier. This book was released on 2012-12-02 with total page 400 pages. Available in PDF, EPUB and Kindle. Book excerpt: Changes in Eukaryotic Gene Expression in Response to Environmental Stress focuses on various aspects of eukaryotic cell's response to heat stress (shock) and other stress stimuli. This book is organized into two major sections, encompassing 17 chapters that reflect the emphasis on research utilizing Drosophila, a variety of animal systems, and plants. This book first provides a brief introduction to the organization, sequences, and induction of heat shock proteins and related genes. It then describes the control of transcription during heat shock from the standpoint of molecular biology and evolutionary variations of the mechanisms in organisms with diverse metabolic needs. It goes on to discuss the issue of coordinate and noncoordinate responses of heat shock genes. It presents a model for post-transcriptional regulation on certain aspects of coordinate and noncoordinate regulations. Chapters 6-12 discuss heat shock proteins and genes and the effects of stress on gene expression of sea urchin, avian, and mammalian cells. The second part of the book focuses on the physiological role of heat shock proteins and genes in plants and fungi. It includes a discussion on experimental problems encountered during studies of the mechanisms of inhibition of photosynthesis by unfavorable environmental conditions. The changes in transcription and translation of specific mRNAs in the developing embryo during heat shock at various temperatures are described. The concluding chapters deal with heat shock response in plants, particularly the response in soybeans and maize, covering both physiological and molecular analyses. Research scientists, clinicians, and agriculturists will greatly benefit from the information presented in this book.
Download or read book Lipids and Biomembranes of Eukaryotic Microorganisms written by Joseph Erwin and published by Elsevier. This book was released on 2012-12-02 with total page 371 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lipids and Biomembranes of Eukaryotic Microorganisms synthesizes the state of knowledge for eukaryotic microorganisms and relates this knowledge to microbial membranes. This book examines each of the major classes of lipids—sterols, fatty acids, phospholipids, and sulfolipids—separately. In each case an attempt has been made to provide a comprehensive summary and to evaluate critically the literature on the occurrence and biosynthesis of these compounds in yeasts, fungi, algae, and protozoa. Physiological functions of these lipids, particularly their role in the membranes of the organisms, are described. In some cases attention has been called to the possible usefulness of lipids as taxonomic criteria. Experimental systems for studying the relation between the structure of lipids and their function in biomembranes are also discussed. These systems include the photosynthetic membranes in organisms such as Euglena, Chlorella, and Chlamydomonas in which the formation of the chloroplasts is susceptible to experimental control; and fatty acid auxotrophic mutants of yeasts and Neurospora in which the fatty acid composition of the membrane lipids can be altered by the experimenter. This book will be of use to lipid biochemists, microbial physiologists, taxonomists, and cell biologists who are interested in the molecular aspects of biomembranes.
