Available in PDF, EPUB and Kindle. Book excerpt: Les chirosciences étudient la préparation, les propriétés et les interactions des molécules chirales. La chromatographie chirale est une technique répandue pour analyser et produire des énantiomères. Son principe réside dans les interactions entre un sélecteur chiral et chaque énantiomère pour donner des complexes diastéréomères labiles avec différentes énergies et une rétention si différente.Cependant, les mécanismes de reconnaissance chirale ne sont pas bien connus, en particulier pour les sélecteurs chiraux les plus efficaces, qui sont à base de polysaccharides (en particulier de la cellulose et des carbamates d'amylose). Par exemple, le rôle du modificateur de phase mobile (co-solvant tel que l'alcool mélangé avec de l'heptane dans HPLC et avec du CO2 dans SFC) n'est pas expliqué dans la plupart des cas. Sur des phases stationnaires chirales à base de polysaccharide, l'effet du modificateur ne peut pas être restreint à la différence de polarité, ce qui entraîne une variation attendue des temps de rétention: plusieurs exemples ont rapporté la perte d'une énantioséparation ou même une inversion de l'ordre d'élution des énantiomères par changer le modificateur alcoolique.Notre travail vise à décrire les effets sur la rétention, l'ordre d'élution et l'enthalpie des complexes, lors de l'utilisation de mélanges de co-solvants dans la phase mobile. La description de ces comportements chromatographiques inhabituels peut aider à améliorer notre compréhension des mécanismes de reconnaissance chirale.

This book was released on 2013-05-20 with total page 489 pages. Available in PDF, EPUB and Kindle. Book excerpt: Proteomic and Metabolomic Approaches to Biomarker Discovery demonstrates how to leverage biomarkers to improve accuracy and reduce errors in research. Disease biomarker discovery is one of the most vibrant and important areas of research today, as the identification of reliable biomarkers has an enormous impact on disease diagnosis, selection of treatment regimens, and therapeutic monitoring. Various techniques are used in the biomarker discovery process, including techniques used in proteomics, the study of the proteins that make up an organism, and metabolomics, the study of chemical fingerprints created from cellular processes. Proteomic and Metabolomic Approaches to Biomarker Discovery is the only publication that covers techniques from both proteomics and metabolomics and includes all steps involved in biomarker discovery, from study design to study execution. The book describes methods, and presents a standard operating procedure for sample selection, preparation, and storage, as well as data analysis and modeling. This new standard effectively eliminates the differing methodologies used in studies and creates a unified approach. Readers will learn the advantages and disadvantages of the various techniques discussed, as well as potential difficulties inherent to all steps in the biomarker discovery process. A vital resource for biochemists, biologists, analytical chemists, bioanalytical chemists, clinical and medical technicians, researchers in pharmaceuticals, and graduate students, Proteomic and Metabolomic Approaches to Biomarker Discovery provides the information needed to reduce clinical error in the execution of research. - Describes the use of biomarkers to reduce clinical errors in research - Includes techniques from a range of biomarker discoveries - Covers all steps involved in biomarker discovery, from study design to study execution

Book excerpt: Economic Evaluation of Pharmacy Services provides the latest on the trend to a more product-centered and service-centered practice, eschewing traditional economic evaluation techniques that focus on product-to-product comparisons in favor of evaluating processes that measure costs and health outcomes. Complete with examples focusing on best practices, including various study designs, types of pharmacy services, and types of outcomes being evaluated, the book emphasizes case studies and examples that help readers understand economic evaluation techniques. Many of these techniques are transferable across countries, especially where there are advanced and stable health systems in place. With the help of this practical guide, readers will gain a thorough understanding of the application of economic evaluation of pharmacy services. - Delivers a practical guide for conducting economic evaluations of hospital and community pharmacy services - Documents the literature around health economic evaluation and innovative pharmacy services - Guides the development of a standardized health economic evaluation tool to evaluate these services
