  1. 1. Glioblastoma heterogeneity and plasticity : Investigating the roles of BMP4 and SOX2

    Författare :Erika Dalmo; Bengt Westermark; Fredrik J. Swartling; Lene Uhrbom; Ana Martin-Villalba; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Glioblastoma; SOX2; BMP4; senescence; plasticity; Oncology; Onkologi; Medicinsk vetenskap; Medical Science; Biology with specialization in Molecular Biology; Biologi med inriktning mot molekylärbiologi;

    Sammanfattning : The malignant primary brain tumor glioblastoma has a dismal prognosis and is distinguished by its heterogeneous character. Current treatment with surgical resection, radiotherapy and adjuvant chemotherapy with the alkylating agent temozolomide does not provide a cure, but simply prolongs survival by a few months.

  3. 2. Temporal dynamics of brain plasticity : characterizing brain structural changes during skill acquisition

    Författare :Tomás Mediavilla; Daniel Marcellino; Alexandra Badea; Umeå universitet; []

    Sammanfattning : Traditionally, structural plasticity in the human brain has been considered to follow a linear or asymptotic increase over the course of training. However, recent studies using structural MRI revealed transient increases in grey matter volume (GMV) with learning. LÄS MER

    Sammanfattning : Several studies have reported that bone marrow (BM)-derived stem cells have the capacity to give rise to cells of different type of tissue; an ability termed stem cell plasticity or transdifferentiation. Controversies exist as to how frequent this phenomenon is, or if it may be explained by alternative mechanisms. LÄS MER

  7. 5. Plasticity and Inflammation following Traumatic Brain Injury

    Författare :Anders Hånell; Niklas Marklund; Lars Hillered; Nikolaus Plesnila; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Traumatic Brain Injury; plasticity; inflammation; Nogo receptor; EphA4; IL-1β; Neurosurgery; Neurokirurgi; Neuroscience; Neurovetenskap;

    Sammanfattning : Traumatic Brain Injury (TBI) mainly affects young persons in traffic accidents and the elderly in fall accidents. Improvements in the clinical management have significantly improved the outcome following TBI but survivors still suffer from depression, memory problems, personality changes, epilepsy and fatigue.
