  1. 11. A path along deep learning for medical image analysis : With focus on burn wounds and brain tumors

    Författare :Marco Domenico Cirillo; Anders Eklund; Veronika Cheplygina; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Deep learning; Medical image analysis; Burn wounds; Brain tumors; Image classification; Image segmentation; Image augmentation; CNNs; GANs;

    Sammanfattning : The number of medical images that clinicians need to review on a daily basis has increased dramatically during the last decades. Since the number of clinicians has not increased as much, it is necessary to develop tools which can help doctors to work more efficiently. LÄS MER

  3. 12. Towards UWB microwave hyperthermia for brain cancer treatment

    Författare :Massimiliano Zanoli; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; treatment planning; microwave hyperthermia; brain cancer;

    Sammanfattning : Despite numerous clinical trials demonstrating that microwave hyperthermia is a powerful adjuvant modality in the treatment of cancers, there have been few instances where this method has been applied to brain tumors. The reason is a combination of anatomical and physiological factors in this site that require an extra degree of accuracy and control in the thermal dose delivery which current systems are not able to provide.

  4. 13. The link between brain size, cognitive ability, mate choice and sexual behaviour in the guppy (Poecilia reticulata)

    Författare :Alberto Corral López; Niclas Kolm; Janette Boughman; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; sexual selection; artificial selection; brain evolution; optomotor test; decision-making; discrimination; assessment; optimal decisions; rational choice; behavioural flexibility; expensive tissue; predation; sex ratio; OSR; maintenance of variation; etologi; Ethology;

    Sammanfattning : Competition over access for mates has led to the evolution of many striking examples of morphological traits and behaviour in animals. The rapid development of the sexual selection field in recent decades have dramatically advanced our understanding of what traits make individuals more successful in attracting mates and how preferences for mates evolve over time.

  5. 14. Post-Ischemic Housing Conditions Influence On Gene Transcription And Translation After Permanent Focal Brain Ischemia In Rats

    Författare :Li-Ru Zhao; Sektion IV; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; rats; brain-derived neurotrophic factor; mRNA; nerve growth factor-induced gene A; corticosteroid receptors; in situ hybridization; Neurologi; neurophysiology; Neurology; neuropsychology; brain ischemia; enriched environment; neuropsykologi; neurofysiologi;

    Sammanfattning : Enriched environment (EE) housing significantly ameliorates neurological deficits induced by cortical brain ischemia without changing infarction size, suggesting that EE-related functional benefits are associated with neuronal plasticity events in the remaining tissue. Brain-derived neurotrophic factor (BDNF), nerve growth factor-induced gene A (NGFI-A) and corticosteroid receptors (mineralocorticoid receptor, MR; glucocorticoid receptor, GR) have been demonstrated to be involved in brain plasticity.

  7. 15. Beyond Survival - Cognition after Pediatric Brain Tumor

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

    Sammanfattning : 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. LÄS MER
