Book Description
Modern Methods of Steroid Analysis reviews modern methods of steroid analysis such as liquid column chromatography, mass spectrometry, and gas chromatography. Topics covered include qualitative and quantitative analysis of plant sterols by gas-liquid chromatography; Raman spectroscopy of steroids; nuclear magnetic resonance; and applications of lanthanide shift reagents. A computerized method for rapid comparison and retrieval of infrared spectral data is also described. This volume is comprised of 22 chapters and begins with an analysis of hormonal steroids using liquid column chromatography, followed by a discussion on the separation of insect molting hormones using high-pressure liquid chromatography. The reader is methodically introduced to the application of gradient elution and thin-layer chromatography to the analysis of corticosteroids and 17-ketosteroids, as well as some aspects of mass spectrometry in steroid analysis. Subsequent chapters explore other methods such as optical rotatory dispersion and circular dichroism, along with radioisotope techniques. In particular, the radioimmunoassay of plasma steroid hormones and plasma aldosterone is considered. This book should be of interest to biochemists.

Book Description
Studies in Analytical Chemistry, Volume 5: Quantitative Analysis of Steroids covers the pharmaceutical aspects of the analysis of steroid hormones. This book is divided into nine chapters that examine the biological-clinical analysis of other important groups of steroids, including sterols, vitamin D, bile acids, cardiac glycosides, and sapogenins. The material in the book is classified according to the main groups of steroids, individual chapters being devoted to sex hormones, corticosteroids, sterols, vitamins D, bile acids, cardiac glycosides, sapogenins, and miscellaneous steroids. The structure of each chapter is the same. In section 1 the fundamentals of the chemistry of the group of steroids in question are outlined. Section 2 provides a detailed description of the use of various spectroscopic, chromatographic, protein-binding and other methods, while Section 3 deals with the main problems encountered in the analysis of the group of steroids in question and with their solution using the methods described in Section 2. This book will prove useful to steroid and analytical chemists.

Book Description
The Biology of Cholesterol and Related Steroids focuses on the study of sterols in relation to living organisms. The publication first takes a look at the analysis of sterols and related steroids and the distribution of sterols and related steroids in nature, as well as the processes of extraction and separation and presence of sterols in plants, fungi, vertebrates, and invertebrates. The text then ponders on biosynthesis of sterols and metabolism of cholesterol. Topics include formation of fatty acid esters of cholesterol, steroid hormones, biosynthetic pathway to sterols, reaction mechanisms, and comparative aspects of sterol synthesis. The manuscript examines the developmental aspects of cholesterol metabolism and sterols in biological membranes. The book also reviews cholesterol synthesis in animal tissues, sterol metabolism in isolated cells, and epidemiology of the plasma cholesterol. Discussions focus on selection of statistical populations, genetic influences, regulation of sterol synthesis, general aspects of sterol metabolism, and removal of cell cholesterol in vivo. The publication is a dependable source of data for biochemists and readers interested in the biology of cholesterol and steroids.

Book Description
Medicinal Chemistry, Volume 19: Quantitative Structure-Activity Relationships of Drugs is a critical review of the applications of various quantitative structure-activity relationship (QSAR) methodologies in different drug therapeutic areas and discusses the results in terms of their contribution to medicinal chemistry. After briefly describing the developments in QSAR research, this 12-chapter volume goes on discussing the contributions of QSAR methodology in elucidating drug action and rational development of drugs against bacterial, fungal, viral, and other parasitic infections of man. Other chapters explore the mode of action and QSAR of antitumor, cardiovascular, antiallergic, antiulcer, antiarthritic, and nonsteroidal antiinflammatory drugs (NSAID) agents. The discussion then shifts to the pharmacologic effects and QSAR analysis of central nervous system agents, steroids, and other hormones. A chapter examines the major chemicals affecting insects and mites, with particular emphasis on the parameters of binding correlation and reactivity for insect and mite enzymes. The concluding chapters cover the limitations of the QSAR approach in the quantitative treatment of drug absorption, distribution, and metabolism. This volume is of great value to medicinal chemists, scientists, and researchers.

Book Description
While there are many books available on methods of organic and biochemical analysis, the majority are either primarily concerned with the application of a particular technique (e.g. paper chromatography) or have been written for an audience of chemists or for biochemists work ing mainly with animaltissues. Thus, no simple guide to modern metho ds of plant analysis exists and the purpose of the present volume is to fill this gap. It is primarily intended for students in the plant sciences, who have a botanical or a general biological background. It should also be of value to students in biochemistry, pharmacognosy, food science and 'natural products' organic chemistry. Most books on chromatography, while admirably covering the needs of research workers, tend to overwhelm the student with long lists of solvent systems and spray reagents that can be applied to each class of organic constituent. The intention here is to simplify the situation by listing only a few specially recommended techniques that have wide currency in phytochemical laboratories. Sufficient details are provided to allow the student to use the techniques for themselves and most sections contain some introductory practical experiments which can be used in classwork.

Book Description
Osteoporosis is one of the most clinically relevant disabling chronic disease encountered in clinical practice. A common cause of osteoporosis is glucocorticoid excess, as glucocorticoids may increase bone resorption, inhibit bone formation, have indirect actions on bone by decreasing intestinal calcium absorption and induce hypercalciuria. This book presents a comprehensive overview of the effects of glucocorticoids on bone metabolism and structure and on the diagnosis and treatment of glucocorticoid-induced osteoporosis. It aims at providing updated information on the pathogenesis, diagnosis and treatment of this often dramatic complication of glucocorticoid excess. Being one of the few publications completely devoted to glucocorticoid-induced osteoporosis it will heighten the awareness of specialists who prescribe glucocorticoids of the clinical relevance of this treatment complication. 'Glucocorticoid-Induced Osteoporosis' is addressed to clinical experts as well as to general practitioners who will both benefit from the comprehensive and integrative view of the management of patients exposed to glucocorticoids.

Book Description
Practical Pediatric Endocrinology in a Limited Resource Setting provides a guide for managing pediatric endocrine problems in a limited resource setting, together with an outline of the bases for these disorders. The book outlines a plan for coming to a likely diagnosis in situations where resources are constrained, and suggests ways to access more sophisticated technologies for diagnostic confirmation and extension of available tools. Further extending and complementing each chapter is a series of scenarios for use as teaching and learning tools. Together with a clinical question, all chapters include a suggested outline for assessment that assists readers facing similar situations in daily practice. Each scenario works through a typical series of deductive steps used to establish a working diagnosis, while considering both a differential diagnosis and reminding readers of current knowledge around the subject matter. - Provides a working knowledge of pediatric endocrinology, from the viewpoint of practical application, for residents and clinicians practicing in settings with scarce material resources - Features clinically based chapters, empahsising workable diagnoses and management plans in limited resource situations - Includes information on Type 1 diabetes mellitus, given its increasing prevalence worldwide - Describes basic research techniques and planning, intended to foster collaboration between colleagues and other centers in clinical or basic research, which can inform clinical practice and drive innovation
