The Rapid Androgen Disruption Activity Reporter (RADAR) Test Guideline describes an aquatic assay that utilizes transgenic Oryzias latipes (O. latipes, Japanese medaka) eleutheroembryos at day post hatch zero, in a multi-well format to detect chemicals active on the androgen axis.

This Test Guideline describes the Medaka Extended One Generation Test (MEOGRT), which exposes fish over multiple generations to give data relevant to ecological hazard and risk assessment of chemicals, including suspected endocrine disrupting chemicals (EDCs). Exposure in the MEOGRT starts with ...

Explains the advantages of using medaka in experimental designs, to facilitate research, and to stimulate progress by adopting medaka as a model animal The second volume of Medaka: Biology, Management, and Experimental Protocols, together with the first volume, helps to familiarize scientists with the advantages of using medaka in experimental designs, to facilitate research using medaka, and to stimulate progress by adopting medaka as a model animal. The second edition expands on the first by providing additional information and current protocols that have been recently developed, or modified, to successfully raise medaka fish under stable culture conditions in the laboratory. This volume explores new technologies developed after 2009, using the fish as a molecular tool in the fields of life science, evolution, ecology, and toxicology. The authors—noted experts in the field—provide the latest information that spans the varied research disciplines and addresses the value to science of medaka's adoption as a model animal. This important book: Explores the advantages of using medaka in experimental designs, to facilitate research Details the most recent protocols to successfully raise medaka fish under stable conditions in the laboratory Explores the most recent developments in the field Provides step-by step specifics for each protocol, allowing researchers to adapt them for use in their own work Written for students and researchers in fish biology and aquaculture, Medaka: Biology, Management, and Experimental Protocols, Volume 2 introduces the cutting edge research in basic and applied biology using medaka as a model animal as well as descriptions of experimental methods and protocols.

This document provides the second edition of Guidance Document 23 on Aqueous-Phase Aquatic Toxicity Testing of Difficult Test Chemicals.

Social pressure to minimize the use of animal testing, the ever-increasing concern on animal welfare, and the need for more human-relevant and more predictive toxicity tests are some of the drivers for new approaches to chemical screening. This book focuses on The Adverse Outcome Pathway, an analytical construct that describes a sequential chain of causally linked events at different levels of biological organization that lead to an adverse health or ecotoxicological effect. While past efforts have focused on toxicological pathway-based vision for human and ecological health assessment relying on in vitro systems and predictive models, The Adverse Outcome Pathway framework provides a simplified and structured way to organize toxicological information. Within the book, a systems biology approach supplies the tools to infer, link, and quantify the molecular initiating events and the key events and key event relationships leading to adverse outcomes. The advancement of these tools is crucial for the successful implementation of AOPs for regulatory purposes.

An Introduction to Interdisciplinary Toxicology: From Molecules to Man integrates the various aspects of toxicology, from "simple molecular systems, to complex human communities, with expertise from a spectrum of interacting disciplines. Chapters are written by specialists within a given subject, such as a chemical engineer, nutritional scientist, or a microbiologist, so subjects are clearly explained and discussed within the toxicology context. Many chapters are comparative across species so that students in ecotoxicology learn mammalian toxicology and vice versa. Specific citations, further reading, study questions, and other learning features are also included. The book allows students to concurrently learn concepts in both biomedical and environmental toxicology fields, thus better equipping them for the many career opportunities toxicology provides. This book will also be useful to those wishing to reference how disciplines interact within the broad field of toxicology. - Covers major topics and newer areas in toxicology, including nanotoxicology, Tox21, epigenetic toxicology, and organ-specific toxicity - Includes a variety of perspectives to give a complete understanding of toxicology - Written by specialists within each subject area, e.g., a chemical engineer, to ensure concepts are clearly explained

This handbook and ready reference highlights a couple of basic aspects of recently developed new methods in modern crop protection research, authored by renowned experts from major agrochemical companies. Organized into four major parts that trace the key phases of the compound development process, the first section addresses compound design, while the second covers newly developed methods for the identification of the mode of action of agrochemical compounds. The third part describes methods used in improving the bioavailability of compounds, and the final section looks at modern methods for risk assessment. As a result, the agrochemical developer will find here a valuable toolbox of advanced methods, complete with first-hand practical advice and copious examples from current industrial practice.

Reproductive and Developmental Toxicology, Second Edition, is a comprehensive and authoritative resource that provides the latest literature on this complex subject with a primary focus on three core components—parent, placenta, and fetus—and the continuous changes that occur in each. Enriched with relevant references describing every aspect of reproductive toxicology, this revised and updated resource addresses the totality of the subject, discussing a broad range of topics, including nanoparticles and radiation, gases and solvents, smoking, alcohol and drug abuse, and metals, amongst others. With a special focus on placental toxicity, this book is the only available reference to connect the three key risk stages, also including discussions on reproductive and developmental toxicity in domestic animals, fish, and wildlife. Completely revised and updated to include the most recent developments in the field, the book is an essential resource for advanced students and researchers in toxicology, as well as biologists, pharmacologists, and teratologists from academia, industry, and regulatory agencies. - Provides a complete, up-to-date, integrated source of information on the key risk stages during reproduction and development - Includes new chapters covering significant developments, such as dose-response assessment for developmental toxicity, juvenile toxicity, and neural tube defects, as well as emerging science, such as stem cell application, toxicoproteomics, metabolomics, endocrine disruption, surveillance and regulatory considerations, and risk assessment - Offers diverse and unique in vitro and in vivo toxicity models for reproductive and developmental toxicity testing in a user-friendly format that assists in comparative analysis
