  1. 1. Multivariate analyses of proteomic and metabolomic patterns in brain tumors

    Författare :Carl Wibom; A Tommy Bergenheim; Henrik Antti; Mikael Johansson; Janne Lehtiö; Umeå universitet; []
    Nyckelord :glioblastoma; meningioma; proteomics; metabolomics; multivariate analyses; onkologi; Oncology;

    Sammanfattning : Glioblastoma multiforme (GBM) is the most common primary brain tumor. Given the current standard of care, the prognosis for patients diagnosed with this disease is still poor. There consequently exists a need to improve current treatments, as well as to develop new ones. LÄS MER

    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Arsenic; trace elements; multivariate analysis; spatial variability; hydrogeology; spatio-temporal variability; Lower Katari Basin; Bolivian Altiplano; alluvial sediments; Arsenik; spårelement; multivariat analys; rumslig variabilitet; hydrogeologi; spatio-temporär variation; Nedre Katari-bassängen; Bolivian Altiplano; alluviala sediment; Land and Water Resources Engineering; Mark- och vattenteknik;

    Sammanfattning : Arsenic (As) contamination in drinking water is a world-wide problem. Thenatural origin of As, its mobility and transport are of great interest in BolivianAltiplano (Lower Katari Basin: LKB and Sothern Poopó Basin: SPB) due topresence of mineral ore deposits, brines, hot springs and volcanic rocks.

  4. 3. Size determination of hyaluronan and multivariate analysis of amyloid prone proteins

    Författare :Linus Malm; Göran Larsson; Henrik Antti; Mary Cowman; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Hyaluronan; Dynamic Light Scattering; GEMMA; Amyloid Aggregation; Multivariate Analysis; Biochemistry; Biokemi; medicinsk biokemi; Medical Biochemistry; fysikalisk kemi; Physical Chemistry;

    Sammanfattning : Background.The extracellular matrix surrounds all cells within our bodies. The glycosaminoglycan hyaluronan is a major component in the extracellular matrix. Despite its structural simplicity it has been shown to be involved in several important functions. LÄS MER

  5. 4. Multivariate integration and visualization of multiblock data in chemical and biological applications

  7. 5. Developing tools for non-target analysis and digital archiving of organic urban water pollutants

    Författare :Cathrin Veenaas; Peter Haglund; Per Liljelind; Christine Gallampois; Mehran Alaee; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Digital archiving; non-target screening; organic pollutants; sewage sludge; GC-MS; GC×GC; LC-MS; time-trend analysis; retention indices; retention time prediction;

    Sammanfattning : This thesis describes efforts to develop robust methods for the creation and use of digital archives of environmental samples, and proposes guidelines based on the results. Digital archives are repositories that store environmental samples digitally. LÄS MER
