Applications Of Mass Spectrometry In Life Safety

Mass spectrometry (MS) along with its hyphenated techniques is capable of high throughput, sensitivity, accuracy and selectivity for the analysis of structure and composition of almost any product. Like in electrophoresis, MS separates mo- cules based on the mass-to-charge ratio. In case of gel electrophoresis (SDS- PAGE), a well-known and efficient bioanalytical technique, proteins bear negative charges but have the same charge density, so proteins are separated according to their size. Similarly, in case of MS analysis, proteins carry the same charge, and are separated by their molecular weight. Unlike SDS-PAGE, however, modern ultra high resolution MS discerns very small mass differences and can resolve and completely identify in a single experiment species of the same nominal mass in complex biological mixtures. Consequently, MS can be used for the structural characterization, identification and sensitive detection of mixtures of biomolecules or for assessing the quality of isolated proteins (purity, integrity, or post-translational modifications, for example), carbohydrates, nucleic acids, drugs, metabolites, pollutants etc. In the post-genome era, MS is continuously developing as one of the most re- able analytical method for elucidating the structure of molecules originating from various biological matrices. The potential of MS for high-sensitive structural a- lyses became unsurpassable after the introduction of electrospray (ESI) and matrix assisted laser/desorption ionization (MALDI) methods, on one hand, and the pos- bility to deduce in detail unknown biopolymer structures by highly accurate mo- cular mass measurement followed by sequencing using dissociation techniques based on multiple stage MS, on the other.

This volume explores the use of mass spectrometry for biomedical applications. Chapters focus on specific therapeutic areas such as oncology, infectious disease and psychiatry. Additional chapters focus on methodology as well as new technologies and instrumentation. This volume provides readers with a comprehensive and informative manual that will allow them to appreciate mass spectrometry and proteomic research but also to initiate and improve their own work. Thus the book acts as a technical guide but also a conceptual guide to the newest information in this exciting field. Mass spectrometry is the central tool used in proteomic research today and is rapidly becoming indispensable to the biomedical scientist. With the completion of the human genome project and the genomic revolution, the proteomic revolution has followed closely behind. Understanding the human proteome has become critical to basic and clinical biomedical research and holds the promise of providing comprehensive understanding of human physiological processes. In addition, proteomics and mass spectrometry are bringing unprecedented biomarker discovery and are helping to personalize medicine.

Concentrating on the natural science aspects of forensics, top international authors from renowned universities, institutes, and laboratories impart the latest information from the field. In doing so they provide the background needed to understand the state of the art in forensic science with a focus on biological, chemical, biochemical, and physical methods. The broad subject coverage includes spectroscopic analysis techniques in various wavelength regimes, gas chromatography, mass spectrometry, electrochemical detection approaches, and imaging techniques, as well as advanced biochemical, DNA-based identification methods. The result is a unique collection of hard-to-get data that is otherwise only found scattered throughout the literature.

With contributions by scientists working in the museum and heritage sector, this textbook provides an overview of the analytical techniques and data processing methods used in modern conservation science. Each chapter deals with one of the common types of conservation materials in turn and provides case study examples of the techniques employed. It will interest students, scientists involved in conservation, and conservators who want to develop their understanding of their collections at a material level.

Handbook of Museum Textiles Textiles have been known to us throughout human history and played a vital role in the lives and traditions of people. Clothing was made by using different materials and methods from natural fibers. There are different varieties of textiles, out of which certain traditional textiles, archaeological findings, or fragments are of cultural, historical, and sentimental value such as tapestries, embroideries, flags, shawls, etc. These kinds of textiles, due to their historical use and environmental factors, require special attention to guarantee their long-term stability. Textile conservation is a complex, challenging, and multi-faceted discipline and it is one of the most versatile branches of conservation. Volume II of the Handbook of Museum Textiles provides precise instruction for conservation techniques to preserve the textile heritage more scientifically and technologically. Additionally, the book covers the most modern techniques used to characterize archaeological textiles and dyes. Progress and innovation in nanotechnology-based interventions in museum textiles are emphasized. Chapters cover the general introduction to biological damage caused by physical and chemical agents and their prevention methods. Information on microscopy and characterization of historical textiles, ancient dyes, and prints is highlighted. Several aspects of assessment of degradation, repair, and stabilization of antique textiles are presented in depth. Experimental research methods for diagnosis and scientific study of fibers and natural dyes using LC-MS and UV-VIS are described. Practical knowledge based on analysis and visualization of historical textiles for the needs of museum conservation, exhibition, digital technology, and virtual museums is addressed as well. Audience It will serve as an educational asset and tool for researchers, art scholars, archaeologists, museum curators, and those who are interested in the field of traditional or historic textile collections.
