Book Description

Environmental Damage to DNA and the Protective Effects of Phytochemicals provides information on the toxicity of natural as well as synthetic chemicals in the living systems. These can lead to DNA damage and the emergence of serious consequences or manifestations causing varied health hazards. In addition, the ten chapters of the book reflect on the possible applications of plants or plant extracts to impart protection for living cells from the xenobiotics-mediated DNA damage.

The book offers comprehensive coverage of the many essential topics in the subject including:

  • Environmental factors and DNA damage
  • Molecular mechanisms associated with DNA damage by various environmental (Physical, Chemical and Biological) factors
  • Synergistic effects of environmental factors
  • Phytochemicals acting both as DNA protectants and genotoxicants
  • Experimental models for the study of the genotoxic potential of environmental factors and protection by phytochemicals

This book connects readers who possess a life sciences background to the current understanding, concept and mechanisms involved in environmental-factors-mediated DNA damage. Scientific terms are introduced, defined, described and placed appropriately in the text. The protective effect of some plant extracts/phytochemicals has also been included.

Environmental Damage to DNA and the Protective Effects of Phytochemicals is intended to cater the need of BSc, MSc and research students who are striving to discover the mechanism(s) associated with protection of DNA by plant-based chemicals. This is the first edition of our book and the valuable suggestions and comments from the readers are solicited.

Ms. Nitika Singh is currently pursuing D. Phil. research programme at the Department of Biochemistry, Faculty of Science, University of Allahabad, India on the research topic concerning xenobiotics mediated biochemical perturbations in mammalian systems and its protection by plant-based principles. She has been a very meritorious student throughout her academic career and received several Merit awards. After graduating from M.G. Kashi Vidyapeeth-Varanasi, she qualified National level examinations of University of Allahabad to pursue her Master Degree Programme in Biochemistry and Doctoral Research Programme in Science during 2014 and 2016, respectively. She has also successfully completed the Diploma Course in French.She is expert in handling several modern techniques applied in Biochemistry, Toxicology and Molecular Biology research (Agarose gel electrophoresis, SDS and Native PAGE, Submarine gel electrophoresis, Centrifugation, DNA isolation, DNA damage and repair assay, and Enzymes assays using Spectrophotometer, Gel Doc Scanning, HPLC, Spectro-fluorometry, and Microscopy). She has published her papers in many peer reviewed international journals of repute. Ms Singh has attended several workshops, conferences and seminars and presented her research papers / posters in many scientific meetings.
