  2. 16. Experimental and clinical perspective on stroke : evaluation by behavior, magnetic resonance imaging and morphology

    Author : Zhengguang Chen; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Cerebral ischemia; stroke; penumbra; behavior; hemodynamics; MRI; perfusion; diffusion; relaxation times; rat;

    Abstract : In order to further improve the diagnostic power of the NEU technique in the use for clinical evaluation of brain lesions, like in stroke patients, a biological model system had to be implemented where the relevant aspects of the brain injury and its effects could be mimicked. Two well controlled and reproducible rat models were chosen, one developed by Bjelke et al. READ MORE

  4. 17. Biophysical modelling in diffusion MRI: The role of tissue microstructure and water exchange

    Author : Markus Nilsson; Lund Medicinsk strålningsfysik; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Diffusion; MRI; tissue microstructure; water exchange; Monte Carlo simulations; white matter;

    Abstract : Diffusion MRI is widely used to study brain structure in vivo. While this technique is often applied to investigations of brain connectivity, it can also be used to infer specific information about the tissue microstructure; for example, to estimate the axon diameter. READ MORE

  5. 18. Epidemiological and Bacteriological Aspects of Spotted Fever Rickettsioses in Humans, Vectors and Mammals in Sweden

    Author : Karin Elfving; Kenneth Nilsson; Eva Hjelm; Björn Olsen; Tomas Bergström; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Rickettsia helvetica; ticks; cultivation; serology; polymerase chain reaction PCR ; DNA sequencing; western blot; electron microscopy; meningitis; seroprevalence;

    Abstract : Rickettsiae are obligate intracellular gram-negative bacteria transmitted by arthropod vectors. Rickettsiae sometimes cause disease in humans, typically with high fever, headache and occasionally an eschar.In Sweden, Rickettsia helvetica, belonging to the spotted fever group, is the only tick-transmitted rickettsia found free in nature.

  6. 19. Thoracic Endovascular Aortic Repair : Clinical and morphological outcomes

    Author : Tina Hellgren; Kevin Mani; Santi Trimarchi; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; Kirurgi;

    Abstract : In the years following its introduction in the late 1980’s, thoracic endovascular aortic repair (TEVAR) rose as a minimally invasive alternative to open surgical repair of thoracic aortic disease. As a result, an expanding group of patients are receiving invasive treatment, even though evidence in the area is still scarce. READ MORE

  7. 20. Spotted Fever Rickettsioses in Sweden : Aspects of Epidemiology, Clinical Manifestations and Co-infections

    Author : Anders Lindblom; Kenneth Nilsson; Björn Olsen; Björn Herrmann; Clas Ahlm; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Rickettsia helvetica; Rickettsia felis; co-infection; erythema migrans; meningitis; serology; PCR; western blot; Infektionssjukdomar; Infectious Diseases;

    Abstract : The spotted fever group rickettsiae are emerging diseases. They cause damage in their hosts by invading the endothelium in small to medium-sized blood vessels, which results in vasculitis that can cause clinical manifestations from most organs. READ MORE
