Unbridled urbanization and development of natural land resources has led to the degradation of our surrounding environment. The air that we breathe, the water we drink and the food we eat is at risk of being contaminated with a plethora of chemical pollutants, some of them being potentially carcinogenic. This presents a challenge to human health. This book attempts to address this challenge in two parts which represent two different approaches. The first part of the book summarizes the alarming effects of environmental contaminants. Various studies depicting the direct relationship of environmental contaminants with cancer incidence have been referenced. Scientific studies have established an inverse relation between cancer and ingestion of dietary phytoconstituents (phytochemicals) in the form of fruits, vegetables and botanical herbs. Plant products as dietary supplements can suppress contaminant toxicity by regulating the resulting reactive species and also by assisting their bodily excretion through Phase 1 and Phase 2 enzyme metabolism. The second part of the book, shifts focus to phytoconstituents which, if included in diet, can prevent the harmful effects of pollutants. The text references numerous studies showing the anti-mutagenic, anti-genotoxic and anti-carcinogenic potential of many plant products. The combination of information about contemporary issues of carcinogenic contaminants in the environment coupled with the references to relevant studies in this handbook will enlighten readers studying courses in environmental chemistry, toxicology, botany, and ecology about environmental toxins and help them understand specific dietary measures known to reduce the toxic impact. Researchers in the field of nutrition can also benefit from the information provided.

Experimental research using spermatozoa, a highly specialized cell with organelles involved in gene transfer, energy supply and cellular motility, has always occupied the forefront of studies in cell and reproductive biology. Several spermatological experiments have focused on the attraction of a spermatozoon toward the egg – sperm chemotaxis or sperm guidance. This process ubiquitously occurs in the reproductive system of many organisms. After its discovery in the late 19th century in plants, sperm chemotaxis is known to play a crucial role in fertilization success in both plants and animals. Spermatology has expanded in focus in recent years, as the structure of molecules relevant to sperm chemotaxis has been recently determined in several species of invertebrates and vertebrates, which promises remarkable progress for understanding events relevant to sexual reproduction. Reflecting upon these trends in the long history of sperm chemotaxis, Flagellar Mechanics and Sperm Guidance gathers leaders in the field of spermatology, who have presented their experimental research on the chemical cues behind flagellate behavior in a variety of organisms including bikonts and spermatozoa of marine invertebrates and vertebrates (fish, amphibians and mammals). Reviews presented in this monograph provide both basic and detailed information on the initiation and activation of sperm motility at spawning, sperm thermotaxis, and other mechanics such as mathematical models of a spermatozoon swimming. A comparison between features of sperm chemotaxis among different organisms is also given. Flagellar Mechanics and Sperm Guidance will stir interest in spermatology research among a broad variety of readers including researchers, Ph.D. students studying reproductive biology and teachers involved in advanced biology courses.

Some arrangements and structures of permanent magnets are hypothesized to exert measurable physiological and pathological effects on living tissues when exposed to the resultant electromagnetic field. From Microbe to Man: Biological responses to artificial static magnetic field-exposure explores the effects of such arrangements based on this hypothesis. The book begins with an explanation of the mechanisms of artificial static magnetic fields (SMFs). This is followed by sequential sections presenting the effects of SMF exposure on living organisms backed by thorough experimental studies (on microbial, animal and human trials). In conclusion, the work reveals the positive nature of SMF treatment and shows that this is indeed a viable alternative to invasive treatment in the case of a number of both acute and chronic conditions, such as stomatological pain and osteoporosis. From Microbe to Man: Biological responses to artificial static magnetic field-exposure is aimed chiefly at medical professionals and the research community studying alternatives to conventional pain medicine and physiotherapy. However, laypeople interested in non-invasive medical treatment options can also benefit from the easy-to-read layout of the contents of this volume.

Age-related degeneration may be reduced or even eliminated, by positively challenging the human being, physically or cognitively, to up-regulate somatic repair functions. Exposure to meaningful information and a challenging environment act as hormetic stressors which, in the context of an increasingly technological setting, may invoke evolutionary mechanisms that lead to a persistent maintenance of homeostasis. Thus, there is a strong link between environmental factors and ongoing health, leading to an individual’s ability to continually adapt to age related challenges. Challenging Ageing: The Anti-senescence Effects of Hormesis, Environmental Enrichment, and Information Exposure explains the role of hormesis in anti-aging processes followed by information on vitagenes, epigenetics, environmental enrichment and germlines. The monograph also brings newer concepts and theories to the fore, such as ‘environmental enrichment’ and ‘technoculture.’ Medical professionals and general readers, alike, will gain a a new perspective on the processes that counter aging processes in the human being.

Enzyme inhibitors play a pivotal role in pharmaceutical and nutraceutical industries. The primary understanding of the action of inhibitors helps pharmacologists during the design process for developing new therapeutic drugs. Most drugs treat various chronic and life threatening diseases owing to their specificity and the potency of enzymes which they can inhibit. Enzyme inhibitors are used to screen various levels of diseases which propel the growth of inhibitors. The potential for enzyme inhibitors in the therapeutics market is very high as the biochemical properties and classes of enzyme inhibiting products are readily available. The other broad aspect of enzyme inhibition is their application in analytical sensors. These sensors assist in monitoring various environmental factors. Understanding the mechanism of inhibition and regeneration of enzymes is a general problem of great importance for many biochemists and biotechnologists especially when using immobilized enzymes. This reference compiles applied information about enzyme inhibitors used in medicine and environmental monitoring applications. Chapters presented in this volume cover special topics including biosensors, crop improvements in agriculture, biofuel production, pesticide and heavy metal detection, and drug therapy for human diseases such as breast cancer, neurological diseases and viral infections.
