  2. 1. Biokinetics and radiation dosimetry of 14C-labelled triolein, urea, glycocholic acid and xylose in man. Studies related to nuclear medicine “breath tests” using accelerator mass spectrometry

    Author : Mikael Gunnarsson; Malmö Medicinsk strålningsfysik; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Clinical physics; radiology; tomography; medical instrumentation; Klinisk fysiologi; radiologi; tomografi; medicinsk instrumentering; Kärnfysik; Nuclear physics; xylose.; glycocholic acid; urea; triolein; Dosimetry; Biokinetic; AMS; Accelerator mass spectrometry; 14C; Breath test;

    Abstract : 14C-labelled substances have been used in biomedical research and clinical medicine for over 50 years. Physicians and scientists however, often hesitate to use these substances in patients and volunteers because the radiation dosimetry is unclear. READ MORE

  4. 2. Evaluations of measurement techniques in functional dyspepsia : electrogastrography, satiety drinking test and 14C-urea breath test

    Author : Shahab Abid; Karolinska Institutet; Karolinska Institutet; []
    Keywords : functional dyspepsia; electrogastrography; 14C urea breath test; satiety drinking test;

    Abstract : The overall aim of this thesis was to evaluate the clinical usefulness of certain measurement techniques that may be helpful in the understanding of functional dyspepsia (FD). Electrogastrography (EGG) parameters were evaluated and found unable to discriminate one specific motility disorder from other motility disorders of the gut. READ MORE

  5. 3. Diagnostic methods in helicobacter pylori infection : development, evaluation and application

    Author : Ann-Sofie Jansson Rehnberg; Karolinska Institutet; Karolinska Institutet; []
    Keywords : H. pylori; Urea Breath Test; Serology; Bleeding disorder; Nitric oxide;

    Abstract : Aim: To develop, evaluate and apply diagnostic methods for H. pylori infection. Materials and Methods: An in-house Urea Breath Test (UBT) was developed and evaluated in three different settings, using serology by ELISA and immunoblot as gold standard. Further, the Heliprobe was evaluated as an alternative diagnostic device. READ MORE
