The book is divided into five major sections, reflecting the range of interest in the exploitation of this assay. The book's scope begins with an introduction section reviewing its genesis for those new to the technique and the current knowledge of the various fields in which it finds wide acceptance. This section sets the scene by explaining why the assay has become the most sensitive and sought after assay in modern toxicology. Next is a whole section that considers various procedures being followed to assess different types of DNA damage in various cell types and is contributed by experts in the respective fields. The third section puts together the specific applications of the assay in the diverse fields ranging from genetic toxicity testing to human monitoring, and environmental toxicology. The fourth section consists of the guidelines and recommendations for the conduct of the assay in in vitro and in vivo systems, based on the recommendations of the International Workgroups on genotoxicity test procedures. Finally, the book draws to a close with an assessment of the statistics used for the understanding of the data generated by the assay. This is a unique reference book as it provides the scientific community with the advances in Comet assay as well as its applications. It also incorporates a detailed section with instant and comprehensive information on the procedure of the assay and the latest protocols being used worldwide as well as statistical analyses to be followed. The book is aimed at students as well as scientists in the area of molecular epidemiology and genetic toxicology.

These volumes chronicle the outbreak and world-wide spread of SARS-Cov-2 (COVID-19) and delineates the role of several disciplines in therapeutic and control measures. Designing safe and effective antiviral drugs are extremely challenging, the drug or chemical must interfere with the virus life cycle without harming the host organism's cells or systems. Viral variation and mutation is another major difficulty in developing and applying appropriate vaccines, antiviral drugs and interventions. By addressing considerations of efficacy and safety of drugs and chemicals used to combat COVID-19, virtually in real-time, these books document and highlight the advances in science and place the toxicology, pharmaceutical science, public health and medical community in a better position to advise in future epidemics.
