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
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

Book Description
Impurity profiling is the common name of a group of analytical activities, the aim of which is the detection, identification/structure elucidation and quantitative determination of organic and inorganic impurities, as well as residual solvents in bulk drugs and pharmaceutical formulations. Since this is the best way to characterise the quality and stability of bulk drugs and pharmaceutical formulations, this is the core activity in modern drug analysis.Due to the very rapid development of the analytical methodologies available for this purpose and the similarly rapid increase of the demands as regards the purity of drugs it is an important task to give a summary of the problems and the various possibilities offered by modern analytical chemistry for their solution. That is the aim of this book.The book is methodology-oriented. In the first chapter some important aspects of the background of impurity-related analytical studies (toxicological, pharmacopoeial aspects, the characterisation of the sources of impurities and the role of impurity profiling in various fields of drug research, production and therapeutic use) are summarised. Chapter two deals with related organic impurities, the strategies for impurity profiling, the use of chromatographic and related separation methods, spectroscopic, and hyphenated techniques. The subject of the third chapter is the identification and determination of residual solvents. The determination of inorganic impurities is discussed in chapter four. The special problems of degradation products as impurities are dealt with in chapter five. A separate chapter has been compiled to deal with one of the most up-to-date problems in contemporary pharmaceutical analysis, the estimation of enantiomeric purity of chiral drugs. Chapter seven is devoted to various approaches to solve the problem of polymorphic modifications as impurities. Since in the broader sense of the word the microbiological purity of drugs and drug products also belongs to this circle, the most important information from this field is summarised in chapter eight. After the mainly methodology-oriented chapters, the final one concentrates on four groups of drugs (peptides, biotechnological products, antibiotics and steroids) in order to demonstrate the use of the methods described earlier.
