Fall 2017
The most often used biofluids in metabolomics and disease biomarker discovery studies in the literature include urine, processed blood (serum or plasma), and cerebral spinal fluid. While investigations using these biofluids have led to numerous innovations in the field of metabolomics, little...

Introduction: Inflammatory bowel disease (IBD), which is consisted of ulcerative colitis (UC) and Crohn’s disease (CD), is a relapsing-remitting inflammatory condition of gastrointestinal tract. Although the exact pathophysiology of IBD is not known yet, it has been suggested that a combination...

Differential 15N2-/14N2-isotope Dansylhydrazine Labeling and LC-MS for Quantification of the Human Carbonyl Metabolome
DownloadFall 2011
The objective of this work was the design and use of paired labeling reagents that are chemically identical but isotopically different to provide a simple and robust means of quantitative mass spectrometry (MS) based metabolome profiling. Herein is presented the differential 15N2-/14N2-isotope...

Feed represents more than half of the costs of livestock production. Residual feed intake (RFI) is a phenotypic measure of feed efficiency that has been proposed as the best approach for genetic improvement of dairy cows. Although RFI is considered as a useful tool for feed efficiency, the...

Environmental Exposures, Gut Microbiota, and Urinary Metabolomic Fingerprint of Crohn’s Disease Patients Who Have Undergone Ileo-colonic Resection
DownloadSpring 2014
Inflammatory bowel disease (IBD) is an idiopathic disease that causes intestinal inflammation and lesions. Canada has one of the highest rates of IBD in the world. One of the major types of IBD is Crohn’s Disease (CD) and a large portion of CD patients will undergo surgical resection in the...

Evaluating the Role of Bacterial Lipopolysaccharide on Etiology and Pathogenesis of Transmissible Spongiform Encephalopathies
DownloadFall 2014
Transmissible spongiform encephalopathies (TSEs) or otherwise known as prion diseases are a class of fatal neurodegenerative diseases related to irreversible brain damage. Presently, there is no effective treatment or preventive strategy for this disease because the etiology and biological...

Evaluation of Derivatization Reaction Conditions for Metabolite Labelling Using Differential Isotopic Labelling for Biological Samples Analyzed by Liquid Chromatography Mass Spectrometry
DownloadFall 2013
The objective of this work was to assess the impact of reaction conditions for isotopic labeling of metabolites prior to analysis using liquid chromatography mass spectrometry (LC-MS). Differential isotope 12C/13C dansyl chloride was used to label metabolites containing either primary amines,...

Huh7.5 Cells Grown in Human Serum as a Model to Study the Effects of Hepatitis C Virus Infection on Lipid Catabolism
DownloadSpring 2018
Our goal is to study the additional elements of the mechanism of steatosis underlying hepatitis C virus (HCV) infection. Human hepatoma Huh7.5 cells cultured in human serum (HS) were used as a model to study the development of steatosis. Huh7.5 cells grown in HS media were chosen to study the...

Identification of biomarkers associated with the onset and progression of ketosis in transition dairy cows
DownloadFall 2016
Ketosis is a common metabolic disorder of transition dairy cows during the early lactation period. Cows with ketosis have lower milk yield and reproductive performance, greater risk of other periparturient diseases, and higher culling rate. Although ketosis has been extensively studied, not many...

Livestock metabolomics is an emerging field of metabolomics that is growing at a fast rate. The ability to rapidly detect and quantify hundreds or even thousands of metabolites within a single sample is helping livestock scientists paint a far more complete picture of animal metabolism and...
