  2. 1. Quantification of 4D Left Ventricular Blood Flow in Health and Disease

    Author : Jonatan Eriksson; Tino Ebbers; Carl-Johan Carlhäll; Gianni Pedrizzetti; Linköpings universitet; []
    Keywords : MRI; relative pressure; 4D flow; quantification; turbulent kinetic energy; dilated cardiomyopathy; magnetic resonance imaging; physiology; cardiac function; diastolic dysfunction;

    Abstract : The main function of the heart is to pump blood throughout the cardiovascular system by generating pressure differences created through volume changes. Although the main purpose of the heart and vessels is to lead the flowing blood throughout the body, clinical assessments of cardiac function are usually based on morphology, approximating the flow features by viewing the motion of the myocardium and vessels.

  4. 2. On posterior capsule opacification

    Author : Karin Sundelin; Göteborgs universitet; []
    Keywords : posterior capsule opacification; quantification; capsulotomy; benefit; intraocular; lens; optic design; Catquest; Evaluation of Posterior Capsule Opacification;

    Abstract : AimsPosterior capsule opacification (PCO) is the most common complication after cataractsurgery. The aim of this study was to increase our knowledge about PCO regardingquantification, treatment effects and how different designs of intraocular lenses(IOLs) influence occurrence. READ MORE

  5. 3. Assessment of attenuation correction methods for quantitative neuro-PET/MR

    Author : Joao M. Sousa; Mark Lubberink; Lieuwe Appel; Håkan Ahlström; Mathias Engström; Ivo Rausch; Radiologi Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; PET; MRI; attenuation correction; 68Ge transmission; quantification; 11C-PE2I; MRAC; DAT; CBF; Medicinsk radiofysik; Medical Radiophysics;

    Abstract : Hybrid PET/magnetic resonance (MR) can provide physiological, functional, and structural information simultaneously, facilitating research in neurological disorders. For quantitative PET, correction for photon attenuation (AC) is necessary. READ MORE

  6. 4. Polychlorinated biphenyls and their metabolites in human blood : Method development, identification and quantification

    Author : Lotta Hofvander; Åke Bergman; Bo Jönsson; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; PCB; polychlorinated biphenyls; metabolites; human blood; Environmental chemistry; Miljökemi;

    Abstract : PCBs are well known environmental pollutants. They are also precursors to metabolites, as the hydroxy-PCBs and the methylsulfonyl-PCBs. This thesis presents a validated methodology for analysis of PCB metabolites and a structural identification of 38 hydroxy-PCBs in human blood. READ MORE

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

    Author : Ola Forslund; Malmö Klinisk mikrobiologi; []
    Keywords : 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;

    Abstract : 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.
