Mutagenicity: Assays and Applications

Mutagenicity: Assays and Applications presents an extensive examination of the detection, assessment and future of mutagenicity, particularly as it concerns human health and the environment. Chapters focused on specific types of mutagens or testing methods for their detection collectively explore the current state of human and environmental mutagenesis, future perspectives and regulatory needs. The test procedures for measuring mutagenicity, their advantages and limitations are described with practical and procedural detail, along with their presentation and data processing aspects. It is an essential reference covering the breadth and depth of the field of mutagenicity studies and regulation.

By providing both important introductory material and practical assays and applications, this book is useful to graduate students, academic and industry researchers and regulators at various stages of their careers, leading to improved risk assessment and regulation.

Vasily N. Dobrovolsky received MS degree in Biotechnology from Moscow Institute of Physics and Technology (Moscow, Russia) and PhD degree in Molecular Biology from the Institute of Bioorganic Chemistry of the Russian Academy of Sciences (IBCh RAS). In 1998, Dr. Dobrovolsky has joined the US Food and Drug Administration as a staff fellow at the National Center for Toxicological Research (Jefferson, Arkansas). Currently as a Senior Scientist, he oversees a group consisting of postdoctoral students, support personnel and staff scientists who are involved in research projects in the field of basic and applied genetic toxicology. His group is using advanced flow cytometry, fluorescence microscopy and next generation sequencing for designing and validating methodologies used for safety assessment of FDA-regulated products. Over the years Dr. Dobrovolsky published over 70 research and scholar articles in peer-reviewed journals and books on detecting in vitro and in vivo mutation, using transgenic and knockout animals in biotechnology and mutation research, characterizing spectra of mutations with high throughput methods. Dr. Dobrovolsky is a member of an influential Genetic Toxicology Technical Committee of the Washington, DC, based Health and Environmental Sciences Institute that advances genetic toxicology and human risk assessment through the international collaboration of experts from industry, government and academia.

Professor Alok Dhawan is currently Director, Institute of Life Sciences, Ahmedabad University, Gujarat on lien from CSIR-Indian Institute of Toxicology Research, Lucknow where he is Principal Scientist and Area Coordinator, Nanomaterial Toxicology Group. He obtained his Ph.D. Biochemistry from University of Lucknow, India in 1991. Professor Dhawan started the area of nanomaterial toxicology in the country and published a guidance document on the safe use of nanomaterials. His group elucidated the mechanism of toxicity of metal oxide nanoparticles in human and bacterial cells. His work has been widely cited. He set up a state of the art nanomaterial toxicology facility at CSIR-IITR.

He pioneered the identification of peripheral biomarkers of exposure, effect and susceptibility to xenobiotics. Using DNA damage in lymphocytes as a biomarker of exposure, he has established the reference values for DNA damage in healthy Indian population. He also developed and validated Drosophila melanogaster for in vivo genotoxicity assessment. These can have far reaching applications in predicting the adverse health effects of drugs and chemicals on human health. He was instrumental in promoting the cause of alternate to animal models in toxicology including in silico models.

Professor Dhawan has won several honours and awards including the INSA Young Scientist Medal in 1994, CSIR Young Scientist Award in 1999 the Shakuntala Amir Chand Prize of ICMR in 2002 and the Vigyan Ratna by the Council of Science and Technology, UP in 2011.

His work in the area of nanomaterial toxicology has won him international accolades as well and he was awarded two Indo-UK projects under the prestigious UK-IERI programme. He also has two European Union Projects under the FP7 and New INDIGO programmes.

He founded the Indian Nanoscience Society in 2007. In recognition of his work he has been elected Fellow, The National Academy of Sciences, India; Fellow, The Academy of Toxicological Sciences, USA; Fellow, The Academy of Environmental Biology; Fellow, Academy of science for Animal Welfare; Fellow--Society of Toxicology (India), Founder Fellow, Indian Nanoscience Society; Vice President--Environmental Mutagen Society of India (2006-07); Member--National Academy of Medical Sciences. He has to his credit over 100 publications in peer reviewed international journals. Five reviews/book chapters. Four patents, one copyright and the Comet assay website www.cometassayindia.org.
