  1. 1. The Impact of Hydrocarbon and Carbon Oxide Impuritiesin the Hydrogen Feed of a PEM Fuel Cell

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Katrin Kortsdottir; KTH.; [2016]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fuel Cell; Hydrogen Impurities; Carbon Monoxide; Carbon Dioxide; Ethene; Propene; Methane; Propane; Toluene; Electrochemically Active Surface Area; Cyclic Voltammetry; Mass Spectrometry; bränslecell; vätgasföroreningar; kolmonoxid; koldioxid; eten; propen; metan; propan; toluen; elektrokemisk aktiv yta; cyklisk voltammetri; masspektrometri; Chemical Engineering; Kemiteknik;

    Abstract : The proton exchange membrane fuel cell generates electricity from hydrogen and oxygen (from air) through electrocatalytic reactions in an electrochemical cell. The Pt/C catalyst, commonly used in PEM fuel cells, is very sensitive to impurities that can interact with the active catalyst sites and limit fuel cell performance. READ MORE

  2. 2. Identification of tissue biomarkers of prognostic significance in pancreatic cancer

    University dissertation from Lund University, Faculty of Medicine

    Author : Dingyuan Hu; Lunds universitet.; Lund University.; Lunds universitet.; Lund University.; Lunds universitet.; Lund University.; [2019]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; pancreatic cancer; proteomics; mass spectrometry; Biomarkers; prognosis; CLCA1; pankreascancer; proteomik; masspektrometri; biomarkörer; prognos; CLCA1;

    Abstract : Pankreascancer, dvs cancer i bukspottkörteln, utgör nu den tredje vanligaste orsaken till död i cancer och kommer om inga genombrott görs att utgöra andra orsak till cancerrelaterad död inom några år (efter lungcancer). Avsaknad av tidiga symtom och en uttalad terapisvikt är bidragande faktorer till den dåliga prognosen. READ MORE

  3. 3. Lipoproteomics A New Approach to the Identification and Characterization of Proteins in LDL and HDL

    University dissertation from Institutionen för molekylär och klinisk medicin

    Author : Helen Karlsson; Linköpings universitet.; Linköpings universitet.; [2007]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; LDL; HDL; Proteomik; Atheroskleros; Masspektrometri; 2-DE; MEDICINE Morphology; cell biology; pathology Pathology Molecular medicine; MEDICIN Morfologi; cellbiologi; patologi Patologi Molekylär medicin;

    Abstract : A proteomic approach was applied to examine the protein composition of low-density lipoprotein (LDL) and high-density lipoprotein (HDL) in humans. LDL and HDL were isolated by density gradient ultracentrifugation, and proteins were separated with twodimensional gel electrophoresis (2-DE) and identified with peptide mass fingerprinting, using matrix-assisted laser desorption/ionization-time of flight mass spectrometry, and with amino acid sequencing using electrospray ionization tandem mass spectrometry.

    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; urine; APOE; FGB; GAL1; LRG1; POLR1E; SERPINA1; STMN1; TOP2A; biomarker; diagnostic biomarker; prognostic biomarker; predictive biomarker; mass spectrometry; western blot; dot blot; immunohistochemistry; IHC; tissue microarray; TMA; urothelium; antibody; antibody-based; urinblåsecancer; biomarkör; diagnos; prognos; urin; proteomik; masspektrometri; immunohistokemi; antikroppar; Molecular Biology; Molekylärbiologi; Molekylär medicin; Molecular Medicine;

    Abstract : Urinary bladder cancer is a heterogeneous disease appearing in different forms, e.g. non-muscle invasive and muscle invasive. For all variants, the expression of proteins is interesting to analyze for diagnostic, predictive, prognostic and drug targeting purposes, since it reflects the altered gene expression causing the cancer.
