DOWNLOAD EBOOKSkin phototoxicity (photoirritation) is defined as an acute toxic response elicited by topically or systemically administered photoreactive chemicals after the exposure of the skin to environmental light. The in vitro reconstructed human epidermis phototoxicity test (RhE PT) is used to identify the phototoxic potential of a test chemical after topical application in reconstructed human epidermis (RhE) tissues in the presence and absence of simulated sunlight.

DOWNLOAD EBOOKPhototoxicity is defined as a toxic response is elicited by topically or systemically administered photoreactive chemicals after the exposure of the body to environmental light. Several classes of photoreactive chemicals could cause phototoxic reactions when activated by light at otherwise non-toxic doses. Phototoxicity can be categorized as photoirritation, photoallergy, and photogenotoxicity. The purpose of this test is to measure the phototoxicity of a chemical. The main event in any phototoxic reaction is the absorption of photons of a wavelength that induces the excitation of the chromophore. Excitation energy is often transferred to oxygen molecules, followed by the generation of ROS (reactive Oxygen Species). Measurements are performed using a spectrometer. The determination of the ROS generation from irradiated chemicals with simulated sunlight is indicative of phototoxic potential.

DOWNLOAD EBOOKEnvironmental Toxicity of Nanomaterials focuses on causes and prevention of environmental toxicity induced by various nanomaterials. In sixteen chapters it describes the basic principles, trends, challenges, and future directions of nanoecotoxicity. The future acceptance of nanomaterials in various industries depends on the impacts of nanomaterials on the environment and ecosystem. This book analyzes the safe utilization of nanotechnology so the tremendous prospect of nanotechnology can be achieved without harming either living beings or the environment. Environmental Toxicity of Nanomaterials introduces nanoecotoxicity, describes various factors affecting the toxicity of nanomaterials, discusses various factors that can impart nanoecotoxicity, reviews various studies in the area of nanoecotoxicity evaluation, and describes the safety and risk assessment of nanomaterials. In addition, the book discusses strategies for mitigating nanoecotoxicity. Lastly, the authors provide guidelines and protocols for nanotoxicity evaluation and discuss regulations for safety assessment of nanomaterials. In addition to environmental toxicologists, this book is aimed at policy makers, industry personnel, and doctoral and postdoctoral scholars.

DOWNLOAD EBOOKExplores the benefits and limitations of the latest high-throughput screening methods With its expert coverage of high-throughput in vitro screening methods for toxicity testing, this book makes it possible for researchers to accelerate and streamline the evaluation and risk assessment of chemicals and drugs for toxicity. Moreover, it enables them to comply with the latest standards set forth by the U.S. National Research Council's "Toxicity Testing in the 21st Century: A Vision and Strategy" and the E.U.'s REACH legislation. Readers will discover a variety of state-of-the-science, high-throughput screening methods presented by a group of leading authorities in toxicology and toxicity testing. High-Throughput Screening Methods in Toxicity Testing is divided into five parts: General aspects, including predicting the toxicity potential of chemicals and drugs via high-throughput bioactivity profiling Assessing different cytotoxicity endpoints Assessing DNA damage and carcinogenesis Assessing reproductive toxicity, cardiotoxicity, and haematotoxicity Assessing drug metabolism and receptor-related toxicity Each chapter describes method principles and includes detailed information about data generation, data analysis, and applications in risk assessment. The authors not only enumerate the advantages of each high-throughput method over comparable conventional methods, but also point out the high-throughput method's limitations and potential pitfalls. In addition, the authors describe current research efforts to make high-throughput toxicity screening even more cost effective and streamlined. Throughout the book, readers will find plenty of figures and illustrations to help them understand and perform the latest high-throughput toxicity screening methods. This book is ideal for toxicologists and other researchers who need to implement high-throughput screening methods for toxicity testing in their laboratories as well as for researchers who need to evaluate the data generated by these methods.
