2. 1. Modeling glioblastoma heterogeneity to decipher its biology

   Author : Yuan Xie; Lene Uhrbom; Massimo Squatrito; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Glioblastoma multiforme; biobank; GBM cells; cell of origin; LGR5; OPCs;

   Abstract : Glioblastoma multiforme (GBM) is the most common and lethal form of primary brain tumor that mainly affects adults. GBM displays remarkable intra- and inter-tumoral heterogeneity and contains a subpopulation of cells named glioma stem cells that is believed to be responsible for tumor maintenance, progression and recurrence.

4. 2. On Brain Oedema

   Author : Mårten Jungner; Anestesiologi och intensivvård; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; traumatic brain injury; brain oedema; fluid therapy; blood-brain barrier;

   Abstract : Traumatic brain injury and bacterial meningitis may at a glance appear as two different disease entities. The host reaction, however, to both trauma and infection involves a strong inflammatory response, with the classical symptomology of rubor, tumor, calor, dolor et functio laesa. READ MORE

5. 3. Proton Magnetic Resonance Spectroscopy in Brain Tumors - Clinical Applications

   Author : Isabella Björkman-Burtscher; Lund Diagnostisk radiologi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; radiology; Clinical physics; Localization; Abscess; Brain; Tumor; Spectroscopy; Magnetic Resonance; tomography; medical instrumentation; Klinisk fysiologi; radiologi; tomografi; medicinsk instrumentering;

   Abstract : Aims: · to present a test phantom and test method for evaluation of proton magnetic resonance spectroscopy (1H-MRS) single volume localization techniques regarding signal contamination; · to describe the introduction of 1H-MRS in the daily routine of a standard MR-unit; · to evaluate the possibilities offered by 1H-MRS to improve preoperative diagnostic accuracy in patients scheduled for stereotactic biopsy of intracranial mass lesions; · to evaluate the possibilities offered by 1H-MRS to improve diagnostics and therapy control in patients with brain abscesses; · to test the hypothesis that 1H-MRS might be useful for differentiation of brain tumors, based on metabolic changes in tissue across brain lesions or surrounding tissue. Results and conclusions: · The test phantom and test method allow quality assessment with good reproducibility. READ MORE

6. 4. Beyond Survival - Cognition after Pediatric Brain Tumor

   Author : Ingrid Tonning Olsson; Lund Pediatrik; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Pediatric Brain Tumor; Cognition; Late sequelae; Cranial Radiation Therapy; Neuropsychology;

   Abstract : Background: Pediatric Brain Tumor (PBT) survivors suffer from cognitive sequelae, especially within the areas of cognitive tempo, attention, executive function and memory. The cognitive difficulties are often accentuated over the years, but knowledge about the long term trajectory is still scarce. READ MORE

7. 5. Cognitive Deficits Reflecting Diffuse and Focal Brain Lesions Caused by Slow Growing Brain Tumors - Low-grade Gliomas

   Author : Lena Ek; Ove Almkvist; Anja Smits; Hans Samuelsson; Stockholms universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Cognition; low-grade glioma; brain tumor; diffuse brain injury; neuropsychological tests; Psychology; Psykologi; Psychology; psykologi;

   Abstract : The overall purpose was to characterize the impact that low-grade glioma (LGG) – a type of slowly growing brain tumor – has on cognitive functions. Paper I was an in-depth analysis of cognitive dysfunction of patients with histological proven LGG. READ MORE
