1. 11. Towards Clinical Implementation of Dynamic Positron Emission Tomography in Neurodegenerative Diseases

   Författare :My Jonasson; Mark Lubberink; Lieuwe Appel; Jens Sörensen; Michel Koole; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Positron emission tomography; PET; Molecular imaging; Quantification; Kinetic modelling; Parametric images; Alzheimer’s disease; Parkinson’s disease; Radiology; Radiologi;

   Sammanfattning : Alzheimer’s disease (AD) and Parkinson’s disease (PD) are the two most common neurodegenerative disorders worldwide. Positron emission tomography (PET), together with suitable biomarkers, can aid in the clin-ical evaluation as well as in research investigations of these diseases. LÄS MER

3. 12. Computational and experimental methods for imaging and dosimetry in 177Lu radionuclide therapy : Classical and novel gamma cameras

   Författare :Daniel Roth; Lund Medicinsk strålningsfysik; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Radionuklidterapi; [177Lu]Lu-DOTA-TATE; Gammakamera; Aktivitetskvantifiering; Dosimetri; CdZnTe; Monte Carlo; Radionuclide therapy; [177Lu]Lu-DOTA-TATE; Gamma camera imaging; Activity quantification; Dosimetry; CdZnTe; Monte Carlo;

   Sammanfattning : Radionuclide therapy (RNT) is a form of radiotherapy that uses unsealed radioactive sources for the delivery of ionising radiation within a patient's body.Radiation dosimetry is not used routinely in all centres, and the RNT field can benefit from more data on pharmacokinetics and absorbed doses (ADs).

4. 13. Combined structural methods to characterize an oligomeric small heat shock protein Hsp21

   Författare :Gudrun Rutsdottir; Biokemi och Strukturbiologi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Small heat shock proteins; chaperones; crosslinking mass spectrometry; Stable isotope labeling; quantification; small angle X-ray scattering; cryo-electron microscopy; combined structural methods; plant stress;

   Sammanfattning : Small heat shock proteins (sHsps) are found in all organisms and evolved early in the history of life, prior to the divergence of the three domains of life (Archaea, Bacteria, and Eukarya). Their malfunction is connected to several different diseases in humans, such as Alzheimer’s and Parkinson’s disease. LÄS MER

5. 14. Genital human papillomaviruses. Studies of their occurrence, type spectrum and expression

   Författare :Ola Forslund; Malmö Klinisk mikrobiologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; mRNA expression; microwell; HPV 70; type determination; CIN; quantification; urine; multifocal infections; hybridization; PCR; HPV; human papillomavirus; Microbiology; bacteriology; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi;

   Sammanfattning : The occurrence of genital human papillomavirus infection was determined in different categories of patients by means of PCR. In high proportion of young women attending an adolescent clinic, the presence of HPV DNA was demonstrated in simultaneously urethral and cervical samples, suggesting that genital HPV infections are often multifocal.

7. 15. Advances in quantitative emission tomography : development and analysis of methods for validation and correction

   Författare :Cathrine Jonsson; Magnus Dahlbom; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; SPECT; Quantification; rCBF; Scatter correction; Phantoms; medicinsk strålningsfysik; Medical Radiation Physics;

   Sammanfattning : The nuclear medicine imaging techniques SPECT and PET are sensitive tools in mapping various physiological and biochemical processes in vivo. This work was devoted to investigations of methodological and physical properties of the SPECT technique as well as developing methods for validation and correction. LÄS MER
