Book excerpt: This unique book is a collaborative effort between researchers at Rutgers University and colleagues from numerous institutions in Uzbekistan and Kyrgyzstan. It will be the first book to document more than 200 of the most important medicinal plants of Central Asia, many whose medicinal uses and activities are being described in English for the first time. The majority of the plants described grow wild in Central Asia with some being endemic, while other species have been introduced to Central Asia but are commonly used in regional plant based medicine. The book contains four introductory chapters. The first and second chapters cover the geography, climate and vegetation of Kyrgyzstan and Uzbekistan, respectively. The third chapter provides a brief history of medicinal plant use and science in Central Asia and the fourth chapter contains general information about phytochemistry. The fifth chapter comprises the bulk of the book and covers 208 medicinal plant species. Nearly all species have one or more high quality, color photographs. Three useful appendices have been included. The first is a glossary of botanical and ecological terms, the second is a glossary of chemistry terms and the third is a glossary of medical terms. During the preparation of this manuscript we found there to be a deficiency in quality reference resources for the translation of many of the technical terms associated with the different branches of science covered in this book. In order to make our job easier we compiled glossaries over the course of preparing the manuscript and have included them feeling that they will be an extremely valuable resource for readers.

Download or read book Nitrogen NMR written by M. Witanowski and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 406 pages. Available in PDF, EPUB and Kindle. Book excerpt: To date nitrogen NMR has been discussed in research papers and review articles throughout the scientific literature. It has been our aim in preparing this book to provide a comprehen sive account of the widely spread applications of nitrogen NMR. The relevant literature has been surveyed from the beginnings of NMR until early 1972. The steady annual growth in the number of references cited since 1965 is ample evidence of the ever increasing importance of the subject. Sufficient theoretical and experimental background is given for an understanding of the applications dealt with in later chapters. The basic principles of NMR are developed with a theoretical approach to chemical shifts and spin-spin coupling constants, particular emphasis being given to nitrogen nuclei. Following this the experimental aspects of nitrogen NMR are adequately described. Special emphasis is given to the observable effects of the nuclear quadrupole moment of the 14 N nucleus. It is appro priate that this topic be dealt with in depth since quadrupolar interactions frequently dominate the information available from a study of the 14 N nucleus and other nuclei spin coupled to it. The applications of nitrogen chemical shift data to organic and inorganic molecules are covered in two extensive chapters which include the effects of paramagnetism on nitrogen NMR.

Download or read book Biochemical Targets of Plant Bioactive Compounds written by Gideon Polya and published by CRC Press. This book was released on 2003-05-15 with total page 864 pages. Available in PDF, EPUB and Kindle. Book excerpt: When introduced to the human body, bioactive metabolites produced by plants for self defense bind to particular biochemical targets, most notably to proteins involved in signaling by hormones and neurotransmitters. This, essentially, is the basis for the effects of herbal medicine. While herbal medicine preparations may act by complex synergistic interactions, molecular explanations of herbal medicine efficacy and side effects ultimately require definition of the biochemical targets of individual plant bioactive constituents. Biochemical Targets of Plant Bioactive Compounds is a comprehensive and user-friendly reference guide to biochemical targets of plant defensive compounds. With 500 pages of tables, it presents a mine of succinctly summarized information relating to bioactive compound structures, plant sources, biochemical targets and physiological effects that can be readily accessed via chemical compound, plant genus, plant common name and subject indexes. With introductory chapters providing reviews of the structural diversity of plant defensive compounds and biochemistry, this book is an invaluable reference for biomedical professionals in the fields of alternative/complementary medicine, natural product chemistry, toxicology, pharmacology, and botany.

Download or read book Nicotinoid Insecticides and the Nicotinic Acetylcholine Receptor written by I. Yamamoto and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 300 pages. Available in PDF, EPUB and Kindle. Book excerpt: The nicotinoids are the most important new class of pesticides, joining the organophosphorus compounds, methylcarbamates, and pyrethroids as the major insecticides. Recently, imidacloprid and related nicotinoids have begun replacing organophosphorus and methylcarbamate compounds as insecticides to control insect pests on major crops. Nicotinoids act on the nicotinic acetylcholine receptor, as does naturally occurring nicotine, but with remarkable effectiveness against insects while being safe for mammals; they are quickly degraded and do not persist in the environment. This volume describes the relationship of nicotinoids to botanical insecticidal alkaloids, their discovery and development as insecticides, and the prospects for their expanded use and for the development of resistance. This book is the first to provide concise, comprehensive information on nicotinoids, their chemistry, mode of action, metabolism, and application in agriculture.
Download or read book Natural Toxins 2 written by Bal Ram Singh and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 529 pages. Available in PDF, EPUB and Kindle. Book excerpt: From beach encounters, aquaculture perils, and processed-food poisoning to snake bites and biological warfare, natural toxins seem never to be far from the public's sight. A better understanding of toxins in terms of their origin, structure, structure-function relation ships, mechanism of action, and detection and diagnosis is of utmost importance to human and animal food safety, nutrition, and health. In addition, it is now clear that many of the toxins can be used as scientific tools to explore the molecular mechanism of several biological processes, be it a mechanism involved in the function of membrane channels, exocytosis, or cytotoxicity. Several of the natural toxins have also been approved as therapeutic drugs, which has made them of interest to several pharmaceutical companies. For example, botulinum neurotoxins, which have been used in studies in the field of neurobiology, have also been used directly as therapeutic drugs against several neuromus cular diseases, such as strabismus and blepherospasm. Toxins in combination with modem biotechnological approaches are also being investigated for their potential use against certain deadly medical problems. For example, a combination of plant toxin ricin and antibodies is being developed for the treatment of tumors. The great potential of natural toxins has attracted scientists of varying backgrounds-pure chemists to cancer biologists-to the study of fundamental aspects of the actions of these toxins.
