Gliomas, which comprise astrocytic, oligodendroglial, and ependymal lesions, are the most frequent primary intracranial tumors. This volume summarizes the enormous advances in our knowledge of gliomas that have occurred during recent years. The first part of the book focuses on the glial tumor entities, with detailed discussion of diagnosis, molecular genetics, and tumor origin. This section also contains a chapter on hereditary tumor syndromes associated with gliomas and the molecular mechanisms underlying these specific diseases. The second part is devoted to the clinical management of gliomas and provides insights into novel developments regarding neuroimaging, surgical management, radiation therapy, adjuvant therapy, experimental approaches, and the neurotoxicity of treatment. The final part of the book addresses angiogenesis and epigenetic regulation of gene expression in gliomas.
The book provides a detailed, up-to-date account of the basics, the technology, and the clinical use of ion beams for radiation therapy. Theoretical background, technical components, and patient treatment schemes are delineated by the leading experts that helped to develop this field from a research niche to its current highly sophisticated and powerful clinical treatment level used to the benefit of cancer patients worldwide. Rather than being a side-by-side collection of articles, this book consists of related chapters. It is a common achievement by 76 experts from around the world. Their expertise reflects the diversity of the field with radiation therapy, medical and accelerator physics, radiobiology, computer science, engineering, and health economics. The book addresses a similarly broad audience ranging from professionals that need to know more about this novel treatment modality or consider to enter the field of ion beam therapy as a researcher. However, it is also written for the interested public and for patients who might want to learn about this treatment option.
Selenium (Se) is an essential dietary trace element participating in the regulation of various physiological functions in both animals and humans through its incorporation into selenoproteins as the amino acid selenocysteine. Among many minerals Se has a special place being the most controversial trace element with a narrow gap between essentiality and toxicity. Indeed there are important environmental issues considering selenium as a pollutant from the one hand and global selenium deficiency on the other. In fact, Se deficiency is considered as a risk factor for the development of various diseases in human and animals. Decreased Se availability from soils as a result of low soil pH and usag...
Hydrothermal Properties of Materials: Experimental Data on Aqueous Phase Equilibria and Solution Properties at Elevated Temperatures and Pressures is designed for any scientists and engineer who deals with hydrothermal investigations and technologies. The book is organized into eight chapters, each dealing with a key physical property of behavior of solutions, so that a reader can obtain information on: hydrothermal experimental methods; available experimental data and the main features of properties behavior in a wide range of temperatures and pressures; and possible ways of experimental data processing for obtaining the derivative properties.
"Respected and known worldwide in the field for his research in plant nutrition, Dr. Horst Marschner authored two editions of Mineral Nutrition of Higher Plants. His research greatly advanced the understanding of plant nutrition ranging from rhizosphere processes to nutrient uptake and utilization by plants in the field. While visiting field experiments in West Africa in 1996, Dr. Marschner contracted malaria and passed away, and until now this legacy title went unrevised. Despite the passage of time, it remains the definitive reference on plant mineral nutrition. Since the last edition, great progress has been made in the understanding of various aspects of plant nutrition. In recent years, the perspective on the mode of action of nutrients in plant metabolism and yield formation has shifted. Much progress has been made in the molecular aspects of nutrient uptake and transport within plants as well as the responses of plants to nutrient deficiency or toxicity. These and many other developments are covered in this long-awaited new edition."--P. [4] of cover.
Evolving science and debate concerning the benefits and risks of consuming fish have resulted in confusion over the years, and national and international food safety agencies have recognized the need to provide useful, clear and relevant information in this regard to consumers. In October 2023, FAO and WHO held the second Joint FAO/WHO Expert Consultation on the Risks and Benefits of Fish Consumption to analyse new scientific evidence on the matter and draw relevant conclusions and recommendations. The overall conclusions of the exercise show that consuming fish provides energy, protein and a range of other nutrients important for health, and that there are benefits related to fish consumption during all life stages (pregnancy, childhood and adulthood). General population studies show that the benefits and individual effects of fish consumption vary depending on overall diet, the characteristics of consumers, and the fish that is consumed.
The 4th International Conference on Selenium in the Environment and Human Health was held 18-21 October 2015 in SPaulo, Brazil. This conference provided an effective scientific communication platform for researchers in different disciplines worldwide to elucidate and better understand those complex roles of Se as both essential nutrient and enviro
