Nanotoxicology In Caenorhabditis Elegans

This book focuses on the toxicity of engineered nanomaterials (ENMs) and their underlying physicochemical, cellular, physiological, and molecular mechanisms. Further, it covers ENMs’ translocation and their targeted organ toxicology, and discusses chemical and pharmacological strategies used to combat nanotoxicity. Engineered nanomaterials (ENMs) are defined as materials with one or more dimensions of less than 100 nm, and have shown considerable promise in several areas of development. At the same time, the potential toxicity of ENMs for human health and environmental organisms is increasingly attracting attention. In addition to the typical properties of model animals, Caenorhabditis elegans is extremely sensitive to environmental toxicants, which makes it the ideal in vivo assay system for toxicological studies. C. elegans has been widely used in toxicity assessment and toxicological studies of environmental toxicants and stresses. This book provides a comprehensive summary of nanotoxicology research on C. elegans.

This book provides the reader with a comprehensive view of analytical methods for nanotoxicology studies. After an introduction to nanomaterials and toxicological studies, the book discusses various characterization methods of nanomaterials and continues with the detection of nanoparticles in vivo as well as in vitro. A variety of techniques in molecular toxicology of nanomaterials is presented, followed by a detailed explanation of interaction between nanoparticles and biomacromolecules, including the structure-toxicity relationships of nanomaterials. Finally, the book concludes with the advantages and challenges of the analytical methods for nanotoxicology.

This book will focus on the molecular basis of oxidative stress induced by toxicants or stresses and various molecular signalling pathways in regulating the toxicity of toxicants or stresses in Caenorhabditis elegans. It will also cover the discussion on the aspects of response signals, G-protein coupled receptors and ion channels, specific molecular signals, and epigenetic signals involved in the regulation of toxicity from toxicants or stresses. The molecular basis for adaptive response for transgenerational toxicity of environmental toxicants or stresses will be further discussed. Nematode Caenorhabditis elegans is a classic model animal with well-described genetic and developmental backgrounds based on the study of life science, and has been further successfully and widely used in both toxicity assessment and toxicological study of various environmental toxicants or stresses. Based on related available data, this book aims at providing a systematic understanding of the knowledge system of molecular toxicology in C. elegans.

“This book uses Caenorhabditis elegans as model animal to introduce the toxicity induction of toxicants at environmentally relevant concentrations under different conditions. It also discusses the systematic introduction of different molecular signaling pathways, as well as G protein coupled receptors and ion channels, in regulating the toxicity of toxicants at environmentally relevant concentrations. The intestinal, neuronal, and germline molecular networks required for the regulation of toxicity of toxicants at environmentally relevant concentrations is further introduced and discussed. This book aims at providing a systematic understanding of the knowledge system on toxicology at environmentally relevant concentrations in Caenorhabditis elegans. ”

This book introduces readers to intestinal and epidermal barriers, and to toxicity induction of environmental toxicants or stresses in the intestine, epidermis, neurons, muscle, and reproductive organs in Caenorhabditis elegans. In addition, it discusses the protective responses of various organs and nematodes’ avoidance behaviour with regard to environmental toxicants or stresses. The intestinal, epidermal, neuronal, and germline signalling pathways required for the regulation of toxicity of environmental toxicants or stresses are also introduced and discussed. As a classic model animal with well-described genetic and developmental backgrounds, the nematode Caenorhabditis elegans has been successfully and widely used in both toxicity assessments and toxicological studies on various environmental toxicants and stresses. Once exposure to certain environmental toxicants has occurred, the toxicants can enter into the primary targeted organs (such as intestinal cells), and even be translocated into secondary targeted organs (such as reproductive organs and neurons). Based on related available data, this book provides a systematic understanding of target organ toxicology in C. elegans.

This book focuses on exposure toxicology in C. elegans. The nematode Caenorhabditis elegans is sensitive to various environmental toxicants and stresses, and has proven to be an important animal model in both molecular and target-organ toxicology. As a result, over the past 30 years, there has been extensive research on the exposure to environmental toxicants or stresses in nematodes. Based on the available data, the book offers an introduction to the exposure system established in nematodes, discussing various aspects of endpoints that can potentially be used to assess the toxicity of environmental toxicants or stresses. Also exploring various factors affecting toxicity induction, and exposure to environmental toxicants and stresses, it allows readers to gain a systematic understanding of exposure toxicology in C. elegans.

Nanomaterials - structures with characteristic dimensions between 1 and 100 nm -exhibit a variety of unique and tunable chemical and physical properties that have made engineered nanoparticles central components in an array of emerging technologies. The use of nanotechnology is increasing; however its potential adverse effects on human health are n

Since the first publication of this book in 2007, the field of nanoscience and nanomedicine continues to grow substantially. This second edition, Nanotoxicology: Progress toward Nanomedicine, enlists internationally recognized experts to document the continuing development and rationale for the safe design of engineered nanomaterials (ENM).
