Download or read book Marine Toxins as Research Tools written by Nobuhiro Fusetani and published by Springer Science & Business Media. This book was released on 2009-01-31 with total page 268 pages. Available in PDF, EPUB and Kindle. Book excerpt: Marine organisms produce a wide array of toxins, many of which are not only structurally unusual, but also show potent and interesting modes of action. Since the discovery of tetrodotoxin, a pufferfish toxin, as a potent and selective blocker of Na+ channels in 1964, it has been widely used as a research tool in pharmacological and physiological research. This has led to the identification of a number of important biological functions for Na+ channels. In recent years, much biological research has been carried out at molecular and cellular levels, and therefore selective inhibitors of enzymes and selective antagonist/agonists of receptors and channels have become increasingly important research tools. Accordingly, interest in using such compounds as reagents has increased. Marine toxins are some of the most popular research tools and have already contributed much to our understanding of biological processes and disease mechanisms.

Download or read book Marine Biotoxins and Seafood Poisoning written by Pedro Reis Costa and published by MDPI. This book was released on 2019-11-21 with total page 114 pages. Available in PDF, EPUB and Kindle. Book excerpt: Marine biotoxins may pose a threat to the human consumption of seafood and seafood products. The increasing global trade and higher demand for seafood products worldwide represents a challenge for food safety authorities, policy makers, food business operators, and the scientific community, in particular, researchers devoted to environmental sciences, toxicology, and analytical chemistry. In addition, due to changes in climate conditions and technological developments, new and emerging marine toxins are being detected in regions where they were previously unknown. This Special Issue highlight studies aiming to the develop detection methods for marine biotoxins for better understanding the dynamics of accumulation/elimination of marine biotoxins and their effects on marine organisms, as well as toxin exposure studies that aim to evaluate the risks associated with the consumption of contaminated seafood.
Download or read book Emerging Marine Biotoxins written by Ana Gago-Mart´ınez and published by MDPI. This book was released on 2019-08-27 with total page 206 pages. Available in PDF, EPUB and Kindle. Book excerpt: The emergence of marine and freshwater toxins in geographical areas where they have never been reported before is a concern due to the considerable impact on (sea)food contamination, and consequently, on public health. Several groups of marine biotoxins, in particular tetrodotoxins, ciguatoxins, and palytoxins, are included among the relevant marine biotoxins that have recently emerged in several coastal areas. A similar situation has been observed in freshwater, where cyanobacterial toxins, such as microcystins, could end up in unexpected areas such as the estuaries where shellfish are cultivated. Climate change and the increased availability of nutrients have been considered as the key factors in the expansion of all of these toxins into new areas; however, this could also be due to more intense biological invasions, more sensitive analytical methods, or perhaps even an increased scientific interest in these natural contaminations. The incidences of human intoxications due to the consumption of seafood contaminated with these toxins have made their study an important task to accomplish in order to protect human health. This Special Issue has a focus on a wide variety of emerging biotoxin classes and techniques to identify and quantify them.

Download or read book Marine Toxins written by Dominick Gray and published by Nova Science Publishers. This book was released on 2016 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: In areas where toxic algal blooms occur, the main affected organisms are shellfish, which, because of their high levels of filtration (clearance rate), accumulate high concentrations of nutrients and toxic phytoplankton in their visceral tissue. This accumulation of toxins in shellfish leads to a distribution of these toxins to their different non-visceral tissues. Chapter One of Marine Toxins: Detection Methods, Chemical and Biological Aspects and Health Effects discusses the detection and quantification of lipophilic marine biotoxins by liquid chromatography tandem mass spectrometry from endemic species and gastropods. Chapter Two presents studies which use the similarity analysis of paralytic shellfish poisoning toxins (PSP-toxins) profile patterns to analyze epidemiological linkage of a group of toxins contaminated bivalves collected between years 2004 and 2015. Chapter Three provide an overview of the current status of biomarker use in the assessment of the effects of marine toxins on bivalve mollusks. Chapter Four reviews the latest research on the biological and clinical effects of caulerpenyne.

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.
