A Closer Look at the Diffusion Equation - - Bog - Nova Science Publishers Inc - Plusbog.dk

Diffusion is a principle transport mechanism emerging widely at different scale, from nano to micro and macro levels. This is a contributed book of seventh chapters encompassing local and no-local diffusion phenomena modelled with integer-order (local) and non-local operators. This book collates research results developed by scientists from different countries but with common research interest in modelling of diffusion problems. The results reported encompass diffusion problems related to efficient numerical modelling, hypersonic flows, approximate analytical solutions of solvent diffusion in polymers and wetting of soils. Some chapters are devoted to fractional diffusion problem with operators with singular and non-singular memory kernels. The book content cannot present the entire rich area of problems related to modelling of diffusion phenomena but allow seeing some new trends and approaches in the modelling technologies. In this context, the fractional models with singular and non-singular kernels the numerical methods and the development of the integration techniques related to the integral-balance approach form fresh fluxes of ideas to this classical engineering area of research. The book is oriented to researchers; master and PhD students involved in diffusion problems with a variety of application and could serves as a rich reference source and a collection of texts provoking new ideas.

Micronucleus Assay - - Bog - Nova Science Publishers Inc - Plusbog.dk

Micronucleus Assay - - Bog - Nova Science Publishers Inc - Plusbog.dk

Micronucleus is defined as the small nucleus that forms whenever a chromosome or its fragment is not incorporated into one of the daughter nuclei during cell division. It is concluded that micronucleus assay can be used for risk prediction, screening, diagnosis and treatment of various chronic diseases. In this Micronucleus Assay: An Overview, the applications of micronucleus assay will be discussed. Ionisating radiations, ultraviolet rays, geogenic or anthropogenic pollutants can induce mutagenic, teratogenic or carcinogenic effects due to the induction of micro or macrolession over DNA. Several models have been used to measure the mutagenic and clastogenic effect of such agents. As such, the authors focus on one of these models: the micronucleus test. The micronucleus test can assess abnormalities earlier in the drug discovery pipeline, making structure/genotoxicity connection a possible system for drug characterization. Additionally, the authors provide knowledge about micronucleus assay and its usage in occupational toxicology studies. It is now recognized as one of the most successful and reliable assays for genotoxic carcinogens. The authors go on to present an overview of the evaluation of micronucleus assay by flow cytometry, reviewing the studies published in the international literature so far that employ different experimental designs for a variety of purposes. Humans can become exposed to a variety of chemical substances that can have adverse biological effects, and the sub-lethal genotoxicity can have the most far reaching and severe consequences like cancer or abnormal progeny as per the cell type involved. Hence, the penultimate chapter focuses on the significance of identifying and predicting potential genotoxic agents by using laboratory markers, thus regulating and preventing exposure to cancer causing agents In the concluding review, generation of micronucleus assay in the bone marrow cells of mice induced by various clastogenic chemicals, drugs, and radiation are elaborately elucidated. Bone marrow cells are easily susceptible to oxidative damage and sensitive to various clastogenic as well as aneugenic agents.

Function and Metabolism of Aging - Yongxia Zhou - Bog - Nova Science Publishers Inc - Plusbog.dk

Function and Metabolism of Aging - Yongxia Zhou - Bog - Nova Science Publishers Inc - Plusbog.dk

Maintaining good metabolic profile plays a significant role in improving the quality of life at aging. Widely recommended physical and psychological strategies include exercise, calorie restriction (such as healthy diet), anti-aging neuroprotective and anti-inflammation therapy. Most occurring risks at middle age range (45-65 years old) are obesity, insulin resistance, inflammation, alteration in the hypothalamus-hypophysis suprarenal axis activity, stress and hypertension that could increase the prevalence of metabolic syndrome. Metabolic syndrome increases with age, particularly for women. Significant associations were seen between imaging measures and cardiovascular risk factors at both baseline and 18-month follow-ups. Both baseline and longitudinal imaging analysis and correlations with neurocogntive tests as well as cardiovascular risk factors could provide distinct and confirmative perspectives relating to the pathophysiology of aging-related diseases such as dementia and diabetes. Significant baseline and longitudinal effects of age, smoking and neuropathological burdens such as amyloid, tau and glucose metabolism provide a complete imaging, neurocognitive and cardiovascular profile for better staging and differentiating different diseases. Together with accurate imaging guidance, early detection and treatment could be achieved with the ultimate goal of improving quality of life at middle age and extending longevity. The aim of this book is intended to provide both beginners and experts in biomedical imaging and health care a broad picture as well as new development in brain function and metabolism of aging using innovative neuroimaging techniques and advanced longitudinal /correlational analyses. Methods and data presented in this book with novel experimental designs and protocols, especially longitudinal investigation of multiple imaging metrics from microvascular, micro-structural to systematic functional, metabolic and neuropathological perspectives will help improving diagnosis and early prevention of common diseases at middle age such as metabolic syndrome and early dementia. Some promising prevention strategies such as arts therapy, aerobic exercise and calorie restriction will be introduced additionally with imaging evidence. Results presented will help improving diagnosis accuracy, staging, and determining phases and trajectories of disease progression with age, endothelial dysfunction and deficits in metabolic syndrome. This book will provide the current state-of-the-art and new frontiers of brain function and metabolic changes at age using multi-parametric functional, structural and molecular imaging techniques in detection, diagnosis and treatment. We will present some forefront and interesting multi-dimensional baseline and longitudinal imaging techniques to serve as a reference and resource book in neuroimaging application and research field. Several distinct detection and application perspectives, including cutting-edge imaging methods from baseline evaluations to longitudinal applications as well as multi-modal and multi-parametric quantifications will be described. The relatively new and advanced data and results together with interesting examples and application demonstrations could help facilitate the generalization, interpretation and applications of these techniques to improve disease diagnosis, quality of life and treatment for metabolic syndrome and brain dysfunction.
