2. 16. The neuropsychology of idiopathic normal pressure hydrocephalus

   Author : Per Hellström; Göteborgs universitet; []
   Keywords : Idiopathic normal pressure hydrocephalus; Neuropsychology; Prospective study; Shunt treatment; Treatment outcome; iNPH scale;

   Abstract : Idiopathic normal pressure hydrocephalus (iNPH) is characterised by an active distension of the cerebral ventricles due to inadequate absorption of cerebrospinal fluid (CSF) into the systemic circulation. The intracranial pressure is within normal limits, the passages between the ventricles and subarachnoid spaces are open, and there is an absence of identifiable antecedents known to reduce CSF absorption.

4. 17. Migration of molecules in the brain : focus on the extracellular space and the cerebrospinal fluid

   Author : Malin Höistad; Karolinska Institutet; Karolinska Institutet; []
   Keywords : Volume transmission; rat; diffusion; striatum; dual-probe microdialysis; delivery; recovery; clearance; uptake; dopamine; metabolism; radiotracer; mannitol; cisterna magna; opioids; peptides; betaendorphin; mu-opioid receptors; mismatch; TH; DBH; immunohistochemistry; fear.;

   Abstract : Three different molecules and three different experimental models were used to study the migration of molecules in the rat brain: a neurotransmitter- dopamine, an extracellular market- mannitol, and a neuropeptide beta-endorphin. Two models in vivo were used to study the diffusion and migration of molecules: dual-probe rnicrodialysis in the striatum, and direct intrastriatal microinjections followed by cerebrospinal fluid sampling from the cisterna magna.

5. 18. Studies on malignant ventricular tachyarrhythmias and their treatment with an implantable defibrillator

   Author : Bengt Sandstedt; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Implantable cardioverter defibrillator; ventricular fibrillation; ventricular tachycardia; predischarge test; defibrillation threshold; discrimination; electrogram morphology; aortic stenosis; hypertrophy; noradrenalin;

   Abstract : Aims: To investigate the hemodynamic, metabolic and autonomic effects of ventricular fibrillation per se during maintained circulation. To study the defibrillation threshold (DFT) and efficacy of a new and thinner ICD lead (DSP) compared with the standard lead (C). READ MORE

6. 19. Blood Vessels, Biomarkers, and Broken Barriers: lnvestigations of the Brain Vasculature in Models of Neonatal Brain lnjuries

   Author : E. Axel Andersson; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; neonatal brain injury; hypoxia ischemia; germinal matrix haemorrhage; blood brain barrier; tight‐junctions; blood vessels;

   Abstract : Brain injury during the perinatal period can lead to lifelong impairment in cognitive and motor function, or an early death. Term neonatal encephalopathy and preterm germinal matrix haemorrhage are two conditions that can irreversibly injure the brain, but clinical tools for diagnosing and treating these pathologies are lacking.

7. 20. Pattern-recognition receptors and neutrophils in cancer inflammation

   Author : Camilla Rydberg Millrud; Karolinska Institutet; Karolinska Institutet; []
   Keywords : ;

   Abstract : Chronic inflammation, induced by the use of tobacco and alcohol, or caused by infections has long been suggested to constitute a risk factor for head and neck squamous cell carcinoma (HNSCC). The innate immunity is the first line of defense against pathogens, comprising physical and chemical barriers, anti-microbial peptides, pattern-recognition receptors (PRRs) as well as different kinds of cells, including neutrophils.
