This laboratory manual will be welcomed by all research scientists involved in the extraction, fractionation and isolation of compounds from natural materials, especially those working with plants. The book is clear and concise, and features practical exercises to illustrate the techniques described in every chapter. It will provide an invaluable research reference tool for those scientists investigating the potential benefits of ethnomedicine and the properties of chemicals isolated from natural flora.
This exciting new book summarizes the known features of both the more traditional genomic aldosterone effects and those modern aspects of non-genomic aldosterone effects discovered within the past few years. International specialists contribute to the scholarship on these issues. Chapters include discussions on traditional genomic mineralocorticoid physiology; mineralocorticoid receptor theory; and rapid non-genomic steroid effects in the brain, kidneys, smooth muscle cells, and lymphocytes.

Labor is the most important of the three traditional factors of production (land, labor and capital), accounting for some 75 per cent of the GDP. It is therefore important to focus on issues of labor economics. In this book the approach taken will be that of the free market philosophy of libertarianism, the perspective that allows the maximum of freedom, consistent with the responsibility of all to respect the equal rights of all others. The position of this book on unions is unique outside of the libertarian movement, and this is indicative of its analysis of several other issues, such as minimum wages. For scholars on the left, it is almost true that unions can do no wrong (for Marxists, t...
A critical review our current understanding of camptothecins, their shortcomings, and of the possibilities for improving their clinical performance. The authors discuss new camptothecin analog development, drug delivery issues for optimizing their anticancer activity, and their potential use in a variety of different cancers. Additional chapters describe what is known about the biochemistry, the pharmacology, and the chemistry of the camptothecins, including the mechanism of topoisomerase and how camptothecins poison this enzyme, the use of animal models in defining the anticancer potential of camptothecins, and the question of camptothecin resistance.
