  2. 1. Nuclease Activity as a Biomarker in Cancer Detection

    Author : Alien Balian; Frank Hernandez; Kajsa Uvdal; Baris Ata Borsa; Ester Boix Borrás; Linköpings universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Nucleases; Nuclease activity; Cancer detection; Diagnosis; Oligonucleotides; Nucleic acid probes; MRI-probes; Activatable probes;

    Abstract : Nucleases are a group of enzymes that cleave the phosphodiester bonds in nucleic acids. As such, nucleases act as biological scissors that exhibit a plethora of fundamental roles, in prokaryotes and eukaryotes, dependent or non-dependent on their catalytic capability. READ MORE

  4. 2. Pressurised Fluid Extraction of Bioactive Species in Tree Barks : Analysis using Hyphenated Electrochemical Mass Spectrometric Detection

    Author : Michelle Co; Charlotta Turner; Per J.R Sjöberg; Kari Hartonen; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pressurised fluid extraction; antioxidants; DPPH; water; ethanol; antioxidant activity; antioxidant capacity; electrochemial detection; mass spektrometry; Chemistry; Kemi; Analytical Chemistry; Analytisk kemi;

    Abstract : Analytical chemistry has developed throughout time to meet current needs. At present, the interest in biorefinery is growing, due to environmental awareness and the depletion of fossil resources. Biomass from agricultural and forestry industries has proven to be excellent raw material for different processes. READ MORE

  5. 3. Assessment of mobile radiometry data in radiological emergencies using Bayesian statistical methods

    Author : Antanas Bukartas; Malmö Medicinsk strålningsfysik; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Mobile gamma spectrometry; Gamma spectrometry; Orphan source; lost source; Ionizing radiation; Bayesian; Activity; position; activity density; reconstruction; UAV; car-borne;

    Abstract : Nuclear technology and the use of radiation sources have been extensively adopted in the modern world. Despite that, a number of radiological accidents, significantly affecting population and the environment, has happened. Few of the most known are accidents in Chernobyl and Fukushima nuclear power plants. READ MORE

  6. 4. Toward fully automatic earthquake detection and processing for tomography in the Hengill area

    Author : Frederic Wagner; Ari Tryggvason; Ólafur Gudmundsson; Roland Roberts; Steven Gibbons; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Earthquake detection; local-earthquake tomography; Iceland; induced seismicity; geothermal activity; Geofysik med inriktning mot seismologi; Geophysics with specialization in Seismology;

    Abstract : This thesis focuses on the automation of seismic data analysis, in particular, event detection, quality assessment of detected events, and preparation of an earthquake catalogue for seismic tomography.The developed event detector uses back-propagation and stacking of a seismic trace attribute with a known velocity model to detect and locate events.

  7. 5. Plasminogen Activator Inhibitor 1 in Platelets - Studies of Synthesis, Activity, and Glycosylation Patterns

    Author : Helén Brogren; Göteborgs universitet; []
    Keywords : PAI-1; platelets; plasma; fibrinolysis; synthesis; polymorphism; glycosylation; activity; platelet mRNA;

    Abstract : Plasminogen activator inhibitor 1 (PAI-1) is the main physiological inhibitor of tissue-type plasminogen activator. Thus PAI-1 plays an important role in decreasing the fibrinolytic activity in human blood. PAI-1 is present in high concentrations in platelets and also in low concentrations in plasma, but the source of plasma PAI-1 is not known. READ MORE
