  1. 1. Metabolite Profiling of Drugs using Mass Spectrometry : Identification of analytical targets for doping control and improvements of the metabolite search process

    Författare :Malin Nilsson Broberg; Mikael Hedeland; Ulf Bondesson; Curt Pettersson; Börje Tidstedt; Peter Van Eenoo; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Mass spectrometry; UHPLC-HRMS; Doping control; Metabolite profile; SARM; Selective Androgen Receptor Modulator; MVDA; Microsomes; Experimental design; Analytisk farmaceutisk kemi; Analytical Pharmaceutical Chemistry;

    Sammanfattning : Doping is defined as the use of prohibited substances or methods by the World Anti-Doping Agency and the aim with doping control analysis is to detect the use of these illicit substances or methods. Substances that are prohibited in human or equine sports have either a positive or negative impact on the performance. LÄS MER

  2. 2. Development of Methods for Protein and Peptide Analysis Applied in Neuroscience Utilizing Mass Spectrometry

    Författare :Johan Pierson; Per Andrén; Ulf Bondesson; György Marko-Varga; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Analytical chemistry; Mass spectrometry; Parkinson’s disease; Metabolism; Profiling Mass Spectrometry; Proteomics; Analytisk kemi; Analytical chemistry; Analytisk kemi;

    Sammanfattning : This thesis describes the utilization of the matrix-assisted laser desorption ionization mass spectrometry (MALDI MS) and electrospray ionization (ESI) MS techniques for analysis of complex brain tissue samples. Direct molecular profiling of biological samples using MALDI MS is a powerful tool for identifying phenotypic markers. LÄS MER

  3. 3. Multivariate profiling of metabolites in human disease : Method evaluation and application to prostate cancer

    Författare :Elin Thysell; Henrik Antti; Janne Lehtiö; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; metabolite profiling; metabolomics; predictive metabolomics; mass spectrometry; GC-MS; biomarkers; chemometrics; design of experiments; multivariate data analysis; prostate cancer; bone metastases; plasma; biologisk kemi; biological chemistry;

    Sammanfattning : There is an ever increasing need of new technologies for identification of molecular markers for early diagnosis of fatal diseases to allow efficient treatment. In addition, there is great value in finding patterns of metabolites, proteins or genes altered in relation to specific disease conditions to gain a deeper understanding of the underlying mechanisms of disease development.

  4. 4. Advances for Biomarker Discovery in Neuroproteomics using Mass Spectrometry : From Method Development to Clinical Application

    Författare :Marcus O.D. Sjödin; Magnus Wetterhall; Jonas Bergquist; Dominic M. Desiderio; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mass Spectrometry; Biomarker; Proteomics; Central Nervous System; Cerebrospinal Fluid; Traumatic Brain Injury; Cloud-Point Extraction; Neuroproteomics; Relative Quantification; Spinal Cord Stimulation; Neuropathic Pain; Analytical Chemistry; Analytisk kemi;

    Sammanfattning : Proteins offer a prominent group of compounds which may be ubiquitously affected in disease and used as biomarkers for early diagnosis, assessing treatment or drug development. Clinical proteomics aim to screen for protein biomarkers by a comprehensive analysis of all proteins expressed in a biological matrix during a certain pathology. LÄS MER

  5. 5. Mass Spectrometry-Based Protein Biomarker Discovery in Pancreatic Cancer

    Författare :Qimin Zhou; Lund Kirurgi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; pancreatic cancer; proteomics; mass spectrometry; biomarkers; diagnosis; prognosis; prediction; BASP1; WT1; YAP1; AGP1;

    Sammanfattning : Background: Pancreatic cancer has the lowest survival rate among all the major cancer types. Although recent decades have seen advances in diagnostic imaging, surgical techniques, perioperative care and oncological treatment, this has not been translated into major improvements in clinical outcome.
