Book Synopsis Marine Bivalve Mollusks and Emerging Pollutants by : Guangxu Liu
Download or read book Marine Bivalve Mollusks and Emerging Pollutants written by Guangxu Liu. This book was released on 2024-03-18. Available in PDF, EPUB and Kindle. Book excerpt: Marine Bivalve Mollusks and Emerging Pollutants: Toxicological Impacts provides the most updated and comprehensive knowledge of the toxicological impacts of a variety of emerging pollutants on marine bivalve mollusk species. In addition to synthesizing recent toxicological findings, the book also discusses toxification mechanisms, current challenges, and future research prospects. Written by international experts, this book assesses new advances in the toxicological impacts of pollutants, including microplastics, bromide flame retardants, nanomaterials, pharmaceutical residues, personal care products, pesticides, and perfluorinated compounds. In addition, it details how these can affect reproduction, embryonic development, metabolism, and immune systems of marine bivalves. Behavioral responses and neuroendocrine regulation is also discussed. Toxification mechanisms are interpreted at both physiological and molecular levels. The book concludes with current research and environmental challenges and potentials for further, future study techniques. Includes the latest findings of pollutant toxicological impacts Interprets recent understandings of underpinning toxification mechanisms Identifies limitations and challenges in current studies

Book Synopsis Biomonitoring of Trace Metals in the Coastal Waters Using Bivalve Molluscs by : Periyadan K. Krishnakumar
Download or read book Biomonitoring of Trace Metals in the Coastal Waters Using Bivalve Molluscs written by Periyadan K. Krishnakumar. This book was released on 2018. Available in PDF, EPUB and Kindle. Book excerpt: Several environmental contaminants including toxic trace metals are being discharged into the coastal environment causing serious threat to marine organisms and posing public health risk. Marine bivalves (mussel, oyster, and clam) have been successfully used as sentinel organisms for monitoring contaminant levels, including trace metals, in coastal waters around the globe. Chemical analyses measure the contaminants present in the biota but do not necessarily reveal potential biological effects. Therefore, the need to detect and assess the effects of contaminants, especially at low concentrations, has led to the development of molecular markers of contaminant effects called biomarkers. Owing to their short time of response, biomarkers in marine bivalves are used as early warning signals of biological effects caused by environmental pollutants. Research into the development and application of accurate biomarker-based monitoring tools for the environmental contaminants has been intensified in several developed countries.

Book Synopsis Integrated Biomarker and Molecular Responses in Marine Bivalve Following Exposure to Environmental Contaminants by : Yanan Di
Download or read book Integrated Biomarker and Molecular Responses in Marine Bivalve Following Exposure to Environmental Contaminants written by Yanan Di. This book was released on 2012. Available in PDF, EPUB and Kindle. Book excerpt: Environmental genotoxicants/carcinogens in the aquatic environment induce complex detrimental impacts on aquatic organisms. Integrated approach is required to comprehensively assess such impacts in terms of animal and environmental health. Biomarkers at different levels of biological organisations, including clearance rates (at individual level), histopathological alterations (at tissue level), DNA strand breaks using comet assay (at cellular level) and transcriptional alterations of key genes determined by real-time quantitative PCR (at molecular level), were designed and applied to analyse the impacts in marine bivalve: Mytilus sp., a classic bio-indicator species for environmental health monitoring, following exposure to selected environmental contaminants (i.e. Benzo([alpha])Pyrene (B([alpha])P), C60 fullerene, and tritium). The performance of biomarkers changed in response to exposures with higher sensitivity for DNA strand breaks and transcriptional alterations of selected genes. In particular, genes representing 7 gene groups (tumour suppressor gene - p53, proto-oncogene - ras, cytochrome P450 family - cyp4y1, MAPKs family - jnk, Bcl-2 family - bax, MDM2 - mdm2 and RAD family - rad51) showed tissue- and chemical-specific expression profiles under selected experimental conditions. A comparison revealed similarity of interplay among these highly conserved genes with mammalian models, suggesting Mytilus sp. could be an ideal model for signalling research in the carcinogenesis process. To my knowledge, this is the first research to detect tissue specific transcriptional alteration of p53 and ras genes in the organism for the analysis of detrimental impacts induced by different environmental genotoxicant/carcinogen exposures. Furthermore, the study is also the first one to include genes which can interplay with each other to function in the regulation of DNA repair, apoptosis and cell cycle arrest in marine organisms. The results suggested that the applied integrated biomarker approach is a comprehensive and sensitive method to monitor environmental health and, marine bivalve Mytilus sp. is an ideal model organism for research on genotoxicant induced carcinogenesis and will shed light on the mechanisms of this complex process in higher organisms, including humans.

Book Synopsis Bivalve Molluscs by : Elizabeth Gosling
Download or read book Bivalve Molluscs written by Elizabeth Gosling. This book was released on 2008-04-15. Available in PDF, EPUB and Kindle. Book excerpt: Bivalve Molluscs is an extremely comprehensive book coveringall major aspects of this important class of invertebrates. As wellas being an important class biologically and ecologically, many ofthe bivalves are fished and cultured commercially (e.g. mussels,oysters, scallops and clams) in a multi-billion dollar worldwideindustry. Elizabeth Gosling who has a huge wealth of research, teachingand hands on experience working with bivalves, has written alandmark book that will stand for many years as the standard workon the subject. Chapters in Bivalve Molluscs covermorphology, ecology, feeding, reproduction, settlement andrecruitment, growth, physiology, fisheries, aquaculture, genetics,diseases and parasites, and public health issues. A fullunderstanding of many of these aspects is vital for all thoseworking in bivalve fisheries and culture. An essential purchase for anyone concerned with this importantclass of animals, copies of Bivalve Molluscs should be onthe shelves of biologists, ecologists, environmental scientists,fisheries scientists and personnel within the aquaculture industry.Copies of the book should be available in all libraries andresearch establishments where these subjects are studied ortaught. Elizabeth Gosling is based at the Galway-Mayo Instituteof Technology, Galway, Ireland.
