  3. 2. Quantitative Bioanalysis : Liquid separations coupled to targeted mass spectrometric measurements of bioactive compounds

    Författare :Björn Arvidsson; Jonas Bergquist; Magnus Wetterhall; Gérard Hopfgartner; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Analytical chemistry; Method development; Enhanced microdialysis; Column switching; Liquid chromatography; Capillary electrophoresis; Electrospray ionization; Mass spectrometry; Triple quadrupole; Time-of-flight; Quantitation; Validation; Analytisk kemi;

    Sammanfattning : Performing quantitative analysis of targeted bioactive compounds in biological samples, such as blood plasma, cerebrospinal fluid or extracts from pig liver, put high demands on the ruggedness of the method acquiring the results. In addition to the complexity of the sample matrix, the bioactive compounds targeted for analysis usually have low levels of natural abundance, further increasing the demand on the analytical method sensitivity.

  4. 3. Benefits of Non-Linear Mixed Effect Modeling and Optimal Design : Pre-Clinical and Clinical Study Applications

    Författare :Charles Ernest II; Andrew Hooker; Mats Karlsson; Bart Ploeger; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmacometrics; optimal design; nonlinear mixed effects models; population models; Pharmaceutical Science; Farmaceutisk vetenskap;

    Sammanfattning : Despite the growing promise of pharmaceutical research, inferior experimentation or interpretation of data can inhibit breakthrough molecules from finding their way out of research institutions and reaching patients. This thesis provides evidence that better characterization of pre-clinical and clinical data can be accomplished using non-linear mixed effect modeling (NLMEM) and more effective experiments can be conducted using optimal design (OD).

  5. 4. Quantitative imaging with PET : performance and applications of 76Br, 52Fe, 110mIn and 134La

    Författare :Mark Lubberink; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Oncology; PET; Positron Emission Tomography; Quantitative Imaging; bromine; iron; indium; lanthanum; Onkologi; Oncology; Onkologi; Oncology; Onkologi;

    Sammanfattning : The use of positron emission tomography (PET) has so far mainly been limited to a few nuclides with short half-lives such as 11C and 18F. Certain applications require nuclides with longer half-lives, such as 76Br and 52Fe. LÄS MER

  7. 5. Quantitative Assessment of Intelligent Transport Systems for Road Freight Transport

    Författare :Gideon Mbiydzenyuy; Blekinge Tekniska Högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Transport telematic services; Assessment; Freight transport; Quantitative; Modeling; Decision support systems;

    Sammanfattning : In this thesis, methods for using computer-based models as support tools for assessing Transport Telematic Services (TTSs) are studied. Such assessments provide one way to understand how TTSs can address problems caused by transportation, such as accidents, emissions, and energy consumption. LÄS MER
