This book was released on 2014 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of the in vitro chromosome aberration test is to identify agents that cause structural chromosome aberrations in cultured mammalian somatic cells. Structural aberrations may be of two types: chromosome or chromatid. The in vitro chromosome aberration test may employ cultures of established cell lines, cell strains or primary cell cultures. Cell cultures are exposed to the test substance (liquid or solid) both with and without metabolic activation during about 1.5 normal cell cycle lengths. At least three analysable concentrations of the test substance should be used. At each concentration duplicate cultures should normally be used. At predetermined intervals after exposure of cell cultures to the test substance, the cells are treated with a metaphase-arresting substance, harvested, stained. Metaphase cells are analysed microscopically for the presence of chromosome aberrations.

Book excerpt: Covering the latest advances in CNS drug development, this bookwill guide all those involved in pre-clinical to early clinicaltrials. The authors describe how recent innovations can acceleratethe development of novel CNS compounds, improve early detection ofefficacy and toxicity signals, and increase the safety oflater-stage clinical trials. The current crisis in the drug development industry iscritically reviewed, as well as the steps needed to correct theproblems, including new government-backed regulations andindustry-based innovations designed to accelerate CNS drugdevelopment in the future. Animal-based models of major CNS disorders are described indetail, and the ability of the latest in vitro and computer-basedmodels to simulate CNS disease states and predict drug efficacy andside-effects are examined. Particular attention is given tothe growing use of biomarkers and how they can be used effectivelyin early human trials as signals of potential drug efficacy, aswell as the increasingly important role of imaging studies to guidedose selection. Cognitive assessments that can be useful indicatorsof effect in patient populations are also discussed. Written by a team of clinical scientists involved in CNS drugtrials for over 20 years, and based on a wealth of drug developmentand clinical trial experience, Critical Pathways to Success inCNS Drug Developmentis full of practical advice forsuccessfully designing and executing CNS drug trials, avoidingpotential pitfalls, and complying with government regulations

Download or read book Genotoxic Impurities written by Andrew Teasdale and published by John Wiley & Sons. This book was released on 2011-03-29 with total page 455 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book examines genotoxic impurities and their impact on the pharmaceutical industry. Specific sections examine this from both a toxicological and analytical perspective. Within these sections, the book defines appropriate strategies to both assess and ultimately control genotoxic impurities, thus aiding the reader to develop effective control measures. An opening section covers the development of guidelines and the threshold of toxicological concern (TTC) and is followed by a section on safety aspects, including safety tests in vivo and vitro, and data interpretation. The second section addresses the risk posed by genotoxic impurities from outside sources and from mutagens within DNA. In the final section, the book deals with the quality perspective of genotoxic impurities focused on two critical aspects, the first being the analysis and the second how to practically evaluate the impurities.
