Cytokines play an important role in regulating the innate and adaptiveimmune systems by different receptors and signaling pathways. As such, they are also implicated in the occurrence of different disorders and diseases. This book presents a comprehensive overview of immunology, the immune system, and cytokines. Chapters cover such topics as the role and importance of tumor necrosis factor (TNF) in the human body, the association of cytokines with different disorders and diseases, and the role of cytokines in dentistry. 180 pp. Englisch.

Buch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -A flurry of recent research on the role of the RNA/DNA-binding proteins TDP-43 and FUS as well as a dozen other factors (e.g., C9ORF72 and profilin) has led to a new paradigm in our understanding of the pathobiology of the motor neuron disease, Amyotrophic Lateral Sclerosis (ALS). How these factors trigger neuromuscular dysfunction is critical for developing more effective ALS therapeutics. The ¿gain-of-toxicity¿ or ¿loss-of-function¿ of these etiological factors is a key question. Recent studies on the imbalance in genome damage versus repair have opened avenues for potential DNA repair-based therapeutics. This book highlights emerging science in the area of ALS and discusses key approaches and mechanisms essential for developing a cure for ALS. 160 pp. Englisch.

Buch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Selected Chapters from the Renin-Angiotensin System aims to provide a comprehensive overview of the most important physiological and pathophysiological roles of the renin-angiotensin system (RAS). The complex and convoluted RAS has been investigated for many years and, through rigorous scientific research, many important and previously unknown components and functions of the RAS have come to light. These discoveries have been crucial in the understanding of this system and provide a basis for effective modulation of the system as part of therapeutic strategies for a number of widespread disorders. New studies are continuing to elucidate the RAS and the mechanisms associated with its functions. This book discusses relevant scientific knowledge about the RAS and intends to introduce the reader to cutting-edge research with an accentuation on the mechanisms at the functional/physiological and molecular/cellular levels. 178 pp. Englisch.

Buch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -In recent years there has been many developments in communication technology. This has greatly enhanced the computing power of small handheld resource-constrained mobile devices. Different generations of communication technology have evolved. This had led to new research for communication of large volumes of data in different transmission media and the design of different communication protocols. Another direction of research concerns the secure and error-free communication between the sender and receiver despite the risk of the presence of an eavesdropper. For the communication requirement of a huge amount of multimedia streaming data, a lot of research has been carried out in the design of proper overlay networks. The book addresses new research techniques that have evolved to handle these challenges. 260 pp. Englisch.

Buch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Regional development is a broad term but can be seen as a general effort to reduce regional disparities by supporting (employment and wealth-generating) economic activities in regions. In the past, regional development policy tended to try to achieve these objectives by means of large-scale infrastructure development and by attracting inward investment¿ (OECD, 2014).A territorial and regional approach to development is crucial in addressing regional challenges, regional economic competitiveness, and reducing socio-economic discrepancies. This book provides a forum to articulate and discuss Africäs regional development issues in view of the rising opportunities within the African region. This volume contains 14 chapters and is organized in four sections: Introduction; Industry, Trade and Investment in Africa; Agricultural Services and the Water-energy-food Nexus in Africa; and Environmental and Cultural Dimensions to Africäs Regional Development. 260 pp. Englisch.

Buch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Raising the average human lifespan by a decade or more will change our world. The future is not about whether this will happen; it is about what we should do when it happens. Even the most pessimistic assertions about the future of our environment are underestimating the extent of the problem. There is simply no model in which more years of life does not equate to more people and in which that does not lead to more crowding, environmental degradation, more consumption, and more waste. Hence, as we prolong life, these environmental crises will be further exacerbated. With current diets and production practices, feeding 7,6 billion people is degrading terrestrial and aquatic ecosystems, depleting water resources, and driving climate changes. The challenges of today are not just population, and it¿s not just consumption, it is waste also. Thanks to things such as cars, planes, big homes, deforestation and so forth, the annual carbon dioxide emissions of an average are three times as high as it should be. It is likely that this signals that the current level of dividends is unsustainable, hence, we use and return little of value to our natural world. In our book, we address the questions related to environmental health challenges that include contamination of air, water, and soil, and car transportation. In order to better understand natural, industrial, and social-environmental hazards, we have to think of them in a broader context (i.e., physical, chemical, biological, and cultural). We hope that the presented publication gives the reader a broader perspective on the issues related to environmental health challenges in contemporary society in the coming years. 190 pp. Englisch.

Buch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Beekeeping worldwide has seen remarkable development in the face of the growing demand for products from bees by consumers who demand increasingly innocuous products that do not harm the environment. However, it should be noted that, recently, problems have arisen in beekeeping production that could become restrictive factors for the worldwide development of beekeeping. This book includes, in simple and accessible terms, very relevant topics such as the effect of pesticides, the impact of diseases and their management, production and analysis of pollen present in honey, DNA analysis, and sustainable management, among others. This book is answering an expected need for accurate and international information for the productive sector. 202 pp. Englisch.

Buch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The imbalance between the production of reactive oxygen species (ROS) and antioxidant defenses determines a state known as oxidative stress. Higher levels of pro-oxidants compared to antioxidant defenses may generate oxidative damage, which, in turn, may lead to modifications in cellular proteins, lipids, and DNA, reducing functional capacity and increasing the risk of diseases. Nevertheless, the clearance of harmful reactive chemical species is achieved by the antioxidant defense systems. These protection systems are referred to as the first and second lines of defense and comprise the classic antioxidants, enzymatic and nonenzymatic defenses, including glutathione. This book presents and discusses the advancement of research on health and diseases and their underlying mechanisms, exploring mainly aspects related to the glutathione antioxidant system. 138 pp. Englisch.

Buch. Etat : Neu. This item is printed on demand - Print on Demand Titel. Neuware -Studies of fluid flow and heat transfer in a porous medium have been the subject of continuous interest for the past several decades because of the wide range of applications, such as geothermal systems, drying technologies, production of thermal isolators, control of pollutant spread in groundwater, insulation of buildings, solar power collectors, design of nuclear reactors, and compact heat exchangers, etc. There are several models for simulating porous media such as the Darcy model, Non-Darcy model, and non-equilibrium model. In porous media applications, such as the environmental impact of buried nuclear heat-generating waste, chemical reactors, thermal energy transport/storage systems, the cooling of electronic devices, etc., a temperature discrepancy between the solid matrix and the saturating fluid has been observed and recognized.Books on Demand GmbH, Überseering 33, 22297 Hamburg 244 pp. Englisch.
