Book excerpt: The National Institute of Standards and Technology (NIST) recently established a Vitamin D Metabolites Quality Assurance Program (VitDQAP) in collaboration with the National Institutes of Health (NIH) Office of Dietary Supplements. Participants in the fourth exercise of this program, the Summer 2011 Comparability Study, were asked to use the methodology of their choice to measure concentrations of 25-hydroxyvitamin D in control and study materials distributed by NIST. The study materials consisted of SRM 968e Fat-Soluble Vitamins, Carotenoids, and Cholesterol in Human Serum (Level 1, Level 2, and Level 3) and SRM 968d Fat-Soluble Vitamins, Carotenoids and Cholesterol in Human Serum (Level 1). SRM 2972, which is comprised of separate ethanolic calibration solutions with known concentrations of 25(OH)D2 and 25(OH)D3, was provided as a control material. Participants provided their data to NIST, where it was compiled and evaluated for trueness relative to the NIST value and concordance within the participant community. A report of results was provided to all participants of the exercise, and laboratories were identified by code numbers known only to them. The results from this fourth exercise are reported along with a summary of the analytical methods used.

Download or read book Metabolomics written by Xianquan Zhan and published by BoD – Books on Demand. This book was released on 2021-09-01 with total page 170 pages. Available in PDF, EPUB and Kindle. Book excerpt: Metabolomics is the methodology and theory to study the metabolome, including targeted approaches based on selected/multiple reaction monitoring (SRM/MRM) and untargeted approaches based on nuclear magnetic resonance (NMR) or mass spectrometry (MS). The metabolome contains all metabolites derived from sugars, lipids, proteins, and nucleic acids in a given biological system, tissue, cell, or body fluid in a metabolic network system. Metabolomic variations directly link to molecular mechanisms of a disease, reliable therapeutic targets, and effective biomarkers for prediction, diagnosis, and prognostic assessment of disease. This book presents new advances in the concept and methodology of metabolomics, as well as applications of metabolomics in the research and practice of medical and life sciences.

Download or read book Plasma Catalysis written by Annemie Bogaerts and published by MDPI. This book was released on 2019-04-02 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plasma catalysis is gaining increasing interest for various gas conversion applications, such as CO2 conversion into value-added chemicals and fuels, N2 fixation for the synthesis of NH3 or NOx, methane conversion into higher hydrocarbons or oxygenates. It is also widely used for air pollution control (e.g., VOC remediation). Plasma catalysis allows thermodynamically difficult reactions to proceed at ambient pressure and temperature, due to activation of the gas molecules by energetic electrons created in the plasma. However, plasma is very reactive but not selective, and thus a catalyst is needed to improve the selectivity. In spite of the growing interest in plasma catalysis, the underlying mechanisms of the (possible) synergy between plasma and catalyst are not yet fully understood. Indeed, plasma catalysis is quite complicated, as the plasma will affect the catalyst and vice versa. Moreover, due to the reactive plasma environment, the most suitable catalysts will probably be different from thermal catalysts. More research is needed to better understand the plasma–catalyst interactions, in order to further improve the applications.

Download or read book Radiation Chemistry written by C.D. Jonah and published by Elsevier. This book was released on 2001-08-23 with total page 777 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the twentieth century, radiation chemistry emerged as a multi-faceted field encompassing all areas of science. Radiation chemical techniques are becoming increasingly popular and are being routinely used not only by chemists but also by biologists, polymer scientists, etc. "Radiation Chemistry: Present Status and Future Trends" presents an overall view of the different aspects of the subject. The chapters review the current status of the field and present the future opportunities in utilizing radiation chemical techniques. This will be of interest to chemists in general and in particular to radiation chemists, chemical kineticists, photochemists, physical-organic chemists and spectroscopists. In view of the diverse nature of the field, the book is a multi-authored effort by several experts in their particular areas of research. Six main areas, both basic and applied, were identified and the book is organized around them. The topics were selected in terms of their relative importance and the contribution of radiation chemistry to the general areas of chemistry, biology and physics. The topics covered are as diverse as gas phase radiation chemistry, the use of radiation chemical techniques, the treatment of water pollutants, the chemical basis of radiation biology, and muonium chemistry. The book also contains an update of the next generation electron accelerators.
