  1. 1. Idiopathic Normal Pressure Hydrocephalus : Cerebrospinal Fluid Tap Test and Magnetic Resonance Imaging as Preoperative Prognostic Investigations

    Author : Johan Virhammar; Elna-Marie Larsson; Katarina Laurell; Kristina Giuliana Cesarini; Magnus Tisell; Uppsala universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; normal pressure hydrocephalus; NPH; cerebrospinal fluid disorders; dementia; MRI; CSF tap test; CBF; ASL; Neurology; Neurologi; Neurokirurgi; Neurosurgery; Radiology; Radiologi;

    Abstract : Idiopathic normal pressure hydrocephalus (iNPH) is a condition with dilated cerebral ventricles but intracranial pressure within normal limits. The symptoms of gait impairment, cognitive decline and urinary incontinence develop gradually. Treatment with shunt insertion results in improvement in eight out of ten patients. READ MORE

  2. 2. Regeneration in the adult brain after focal cerebral ischemia : exploration of neurogenesis and angiogenesis

    Abstract : Background: Ischemic stroke ranks as the third major cause of clinical mortality and the leading cause of handicap in adults. Each year, stroke occurs in about 30,000 Swedes. The severity of an acute ischemic stroke depends mainly on the degree and duration of local cerebral blood flow (lCBF) reduction. READ MORE

  3. 3. The role of reactive oxygen species in traumatic brain injury : Experimental studies in the rat

    Author : Niklas Marklund; Uppsala universitet; []

    Abstract : Traumatic brain injury (TBI) is a major cause of mortality and disability. As common sequelae in survivors of TBI are disabling functional, emotional and cognitive disturbances, improved treatment of TBI patients is urgently needed. At present, no neuroprotective pharmacological treatment exists. READ MORE

  4. 4. Assessment of attenuation correction methods for quantitative neuro-PET/MR

    Author : Joao M. Sousa; Mark Lubberink; Lieuwe Appel; Håkan Ahlström; Mathias Engström; Ivo Rausch; Radiologi Uppsala universitet; []

    Abstract : Hybrid PET/magnetic resonance (MR) can provide physiological, functional, and structural information simultaneously, facilitating research in neurological disorders. For quantitative PET, correction for photon attenuation (AC) is necessary. READ MORE

  5. 5. Studies of penta-decameric binding proteins: AP-4 and CBF-A

    Author : Alaitz Aranburu; Immunologi; []

    Abstract : Each immunoglobulin (Ig) V gene segment contains an upstream promoter region. The octamer element and the TATA box are the only elements that are conserved in all Ig promoters. The presence of the octamer element is necessary, but not sufficient to support high levels of transcription. READ MORE
