Book Description
Quantitative analysis of endogenous biomolecules offers a wealth of clues to understand cell biology and disease mechanisms. Mass spectrometry (MS) has become a foremost technology for the study of biomolecules and their dynamic alterations involved in disease processes. This dissertation is devoted to the development of novel and improved MS-based metabolomic and proteomic methodologies and the application to human disease studies. Specifically, both label-free and stable isotope labeling strategies have been developed for the analysis of metabolites, peptides, and proteins in various biological systems. Label-free methods provide straightforward measurements of biomolecules and are combined with advanced bioinformatics tools for biomarker discovery. Stable isotope labeling, particularly custom DiLeu, iDiLeu, and mdDiLeu tags, offers high-throughput and accurate quantification of biomolecules. Novel online software platform has also been developed for automated omics data analysis. The advancements of analytical methodologies in this work have been mainly achieved on standard flow liquid chromatography (LC)-MS, nanoflow LC-MS, and capillary electrophoresis (CE)-MS platforms. Comprehensive metabolomic and proteomic studies have been successfully applied to disease biomarker discovery for human Preclinical Alzheimer's Disease and Lower Urinary Tract Symptoms in human and mouse models.

Book Description
The efficient analysis of polar and charged metabolites in biological samples remains a huge challenge in the field of metabolomics. Over the past years, novel mass spectrometry-based analytical tools have been developed to enable the sensitive and efficient profiling of polar ionogenic metabolites in various biological samples. This book gives the reader a comprehensive overview of these recent technological developments. Topics covered include the use of chemical labelling strategies for allowing the analysis of polar metabolites using reversed-phase liquid chromatography–mass spectrometry (RPLC-MS) and the latest methodological developments in RPLC-MS, hydrophilic interaction liquid chromatography (HILIC)-MS and ion-pair LC-MS approaches. Attention is also paid to developments in nano-LC-MS and capillary electrophoresis–mass spectrometry methods specifically for profiling polar metabolites in small volume biological samples. The utility of ion-mobility MS and NMR spectroscopy will also be outlined. Sample preparation is the key part in the analytical workflow employed for metabolomics. Therefore, ample emphasis will be given on recent solid-phase extraction and solid-phase micro-extraction methods. Finally, analytical techniques for chiral metabolic profiling will also be considered. Discussing the state-of-the-art of the proposed topics in one single book for probing the polar metabolome, using relevant examples, is unique and needed in the metabolomics field. This book has relevance and appeal to an international audience of analytical and biomedical researchers in industry and academia.

Book Description
This dissertation describes advances in mass spectrometry-based analysis of the human proteome and applies the most current technologies to investigations of age, neurodegeneration and stress. Although direct protein measurements in human tissues provide valuable insight into the development and progression of disease, the complex and dynamic nature of human proteomes provides several challenges. Chapter 1 details some of these hurdles along with the basic concepts of bottom-up proteomics in terms of sample preparation and instrument operation. Chapter 2 describes regional protein signatures for nine neuroanatomically distinct regions of the aged human brain. These region-specific proteins are then compared to proteins associated with Alzheimer's disease (AD). An efficient and scalable method for proteomic analysis of AD in cerebrospinal fluid is demonstrated in Chapter 3 using an age- and sex-matched sample cohort. In Chapter 4, a proteomic analysis is performed on saliva of soldiers before and after a simulated combat training exercise in order to quantify the proteomic effects of stress. To expand the method development toolkit for proteomics of human tissues and biofluids, a machine learning model is developed for predicting peptides' transmissive compensating voltage when using high field asymmetric waveform ion mobility spectrometry (FAIMS)(Chapter 5). Conclusions and future directions for these projects, including expanded analyses and continued technological development are discussed in Chapter 6. A chapter conveying aspects of this dissertation to a general public audience is included after the conclusion (Chapter 7).

Book Description
This book presents an overview of computational and statistical design and analysis of mass spectrometry-based proteomics, metabolomics, and lipidomics data. This contributed volume provides an introduction to the special aspects of statistical design and analysis with mass spectrometry data for the new omic sciences. The text discusses common aspects of design and analysis between and across all (or most) forms of mass spectrometry, while also providing special examples of application with the most common forms of mass spectrometry. Also covered are applications of computational mass spectrometry not only in clinical study but also in the interpretation of omics data in plant biology studies. Omics research fields are expected to revolutionize biomolecular research by the ability to simultaneously profile many compounds within either patient blood, urine, tissue, or other biological samples. Mass spectrometry is one of the key analytical techniques used in these new omic sciences. Liquid chromatography mass spectrometry, time-of-flight data, and Fourier transform mass spectrometry are but a selection of the measurement platforms available to the modern analyst. Thus in practical proteomics or metabolomics, researchers will not only be confronted with new high dimensional data types—as opposed to the familiar data structures in more classical genomics—but also with great variation between distinct types of mass spectral measurements derived from different platforms, which may complicate analyses, comparison, and interpretation of results.
