Описание: The increasing number of publications that use tellurium clearly demonstrates the important role of tellurium compounds as unique and powerful tools in a broad range of organic chemical manipulations, often characterized by their selective behavior. Tellurium in Organic Synthesis provides an overview of the principal aspects of organic tellurium chemistry. Many chapters have been enriched and updated in this second edition. New chapters include overviews of toxicology and pharmacology and a review on the preparation and reactivity of several tellurium heterocycles. The first part of the book focuses on the preparation of selected inorganic tellurium compounds and on the main classes of organotellurium compounds. The second part, and main interest of the book, details the use of these inorganic and organic compounds as reagents to perform specific organic manipulations and synthesis. Reactions covered include reduction, formation and reaction of anionic species, deprotection, tellurium cyclizations, formation of alkenes, use of vinyllic tellurides, free radical chemistry, transmetallations, and removal of tellurium.

Описание: From a new perspective, namely focusing on the interaction of selenium and mercury, this thesis provides new insights into traditional research on biogeochemical cycles of mercury in soil-plant interaction and associated human exposure and risks. The subject of this thesis is both valuable and timely, providing essential information not only on selenium-mercury interaction in the soil-plant system but also on how to assess the combined benefits and risk of co-exposure to mercury and selenium. This work also sheds light on future aspects regarding prevention, remediation and risk management for environmental mercury contamination. Presenting high-quality papers published in leading international SCI journals such as Environmental Health Perspectives and Environmental Science & Technology and having been recognized with the Special Award of Presidential Scholarship Award and Excellent Doctoral Dissertations Prize of the Chinese Academy of Sciences (CAS), this thesis offers a valuable resource for scientific communities, policy-makers and non-experts who are interested in this field. Dr. Hua Zhang works at the Norwegian Institute for Water Research (NIVA), Oslo, Norway.

Описание: In the current edition, Selenium: Its Molecular Biology and Role in Human Health expands extensively on the previous editions providing readers with the most significant advances in the rapidly developing selenium field. Evidence from epidemiology and veterinary science supports the essential role of selenium in (human) health, but its split personality in both preventing and supporting cancer and also in promoting insulin resistance has become more clearly defined. The pivotal role of glutathione peroxidase 4 in a new process of programmed cell death, ferroptosis, brings new impetus to the field. Recently defined mutations in selenoprotein and biosynthesis factor genes have been identified in patients, and the resulting disorders further emphasize the significance of selenoproteins in human health. The mechanism of selenoprotein biosynthesis, the functions of selenoproteins, and the roles of dietary selenium have been further elucidated, and new regulatory mechanisms involving selenoproteins discovered. The book, therefore, covers the breadth of current selenium research. With up-to-date chapters written by leaders in their fields, it serves as an invaluable resource for novices as well as specialists.
