2. 1. Nuclear magnetic resonance and microcirculation: The influence of pulsatile brain-tissue motion on measurements of intravoxel incoherent motion and assessment of haemodynamics using exo- and endogenous tracers

   Author : Ronnie Wirestam; Lund Medicinsk strålningsfysik; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; diagnostic radiology; cortical activation; diffusion; tumor; tumour; ischemic stroke; ischaemic stroke; tracer kinetics; bolus tracking; phase mapping; brain motion; intracranial dynamics; blood flow; haemodynamics; vascularity; MRS; perfusion; MRI; magnetic resonance; Clinical physics; radiology; tomography; medical instrumentation; Klinisk fysiologi; radiologi; tomografi; medicinsk instrumentering;

   Abstract : In this project, the potential of magnetic resonance (MR) imaging and spectroscopy in studies of microcirculation and haemodynamics was evaluated. The spatial and temporal characteristics of human pulsatile brain-tissue movements in healthy individuals, relevant for the understanding of the cerebrospinal-fluid (CSF) circulation and the pathogenesis of hydrocephalus, were thoroughly investigated.

4. 2. Language ability in patients with low-grade glioma - detecting signs of subtle dysfunction

   Author : Malin Antonsson; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Low-grade glioma; language ability; high-level language; tumour surgery; brain tumour; writing; keystroke logging;

   Abstract : Background: Low-grade glioma (LGG) is a slow-growing brain tumour often situated in or near areas involved in language and/or cognitive functions. Consequently, there is a risk that patients develop language impairments due to tumour growth or surgical resection. READ MORE

5. 3. Inverse Mathematical Models for Brain Tumour Growth

   Author : Rym Jaroudi; George Baravdish; Tomas Johansson; Trucu Dumitru; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : We study the following well-established model of reaction-diffusion type for brain tumour growth:This equation describes the change over time of the normalised tumour cell density u as a consequence of two biological phenomena: proliferation and diffusion.We discuss a mathematical method for the inverse problem of locating the brain tumour source (origin) based on the reaction-diffusion model.

6. 4. Academic Performance in Swedish Ninth Grade Students Treated for Brain Tumours

   Author : Malin Lönnerblad; Eva Berglund; Klas Blomgren; Ingrid van’t Hooft; Lisa Thorell; Stockholms universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; School performance; academic performance; brain tumour; academic grades; national tests; delayed graduation; theoretical subjects; practical and aesthetic subjects; specialpedagogik; Special Education;

   Abstract : The overall aim of this thesis was to investigate how children in Sweden treated for brain tumours performed in their ninth year at school compared with matched controls. The studies investigated grades and results from national tests in the theoretical subjects of Swedish, English, and mathematics; grades in the practical and aesthetic subjects of art, crafts, music, home and consumer studies, physical education and health; and the frequency of delayed graduation and qualification for school years 10-12 (corresponding to upper-secondary school or high school).

7. 5. Consequences of brain tumours from the perspective of the patients and of their next of kin

   Author : Tanja Edvardsson; Gerd Ahlström; Jerker Rönnberg; Pär Salander; Örebro universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; brain tumour; low-grade glioma; cancer; patient’s perspective; next of kin’s perspective; duration of disease onset; coping; subjective quality of life; content analysis; Disability research; Handikappsforskning; Handikappvetenskap; Disability Science;

   Abstract : A disease has consequences not only for the afflicted person but also for those who interact with him or her. A low-grade glioma is a brain tumour whose regarding its psychosocial implications for adult patients and their next of kin has received little attention in the literature. READ MORE
