1. 1. Cerebral Injury in Perinatal Asphyxia, epidemiological, clinical, neurophysiological and neuromatabolic investigations

   Författare :Kristina Thorngren-Jerneck; Lund Pediatrik; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; neuropsychology; neurophysiology; Neurologi; neuropsykologi; neurofysiologi; Neurology; Pediatri; Pediatrics; S100; EEG; CMRgl; cerebral glucose metabolism; FDG-PET; CP; infant; perinatal asphyxia; hypoxia-ischemia;

   Sammanfattning : Perinatal asphyxia with hypoxic ischemic encephalopathy (HIE) is the most important cause of perinatal mortality and cerebral palsy (CP) in infants born at term. The aim of the thesis was to investigate epidemiology of perinatal asphyxia, and to investigate early clinical neurological symptoms after perinatal asphyxia in relation to cerebral glucose metabolism (CMRgl) measured by 18-FDG-PET, neurophysiological function, some biochemical markers, also in relation to long-term outcome.

3. 2. Stroke in geriatric patients - Aspects of depression, cognition and motor activity

   Författare :Berit Agrell; Geriatrik; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; stroke; laterality; rating scales; motoractivity; aphasia; neglect; disability; depression; cognition; Neurology; neuropsychology; neurophysiology; Neurologi; neuropsykologi; neurofysiologi;

   Sammanfattning : Six depression rating scales, GDS, Zung, CES-D, CPRS-D and Cornell, were compared in 40 patients. The validity was good for all scales except for the Cornell scale. A comprehensive investigation was done in 116 elderly stroke patients. There was no difference in prevalence and severity of post-stroke depression in relation to side of lesion. LÄS MER

4. 3. Aspects of proteinase-activated receptor-2: A sensor of enzymatic activity at the cell surface

   Författare :Anna-Karin Alm; Institutionen för experimentell medicinsk vetenskap; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; neuropsychology; Neurology; endometrium.; coagulation; signalling; proteinase; G-protein; cell; receptor; neurophysiology; Neurologi; neuropsykologi; neurofysiologi;

   Sammanfattning : Information about extracellular proteolytic activity is transduced to the cell by a transmembrane G-protein coupled receptor subfamily. These receptors are activated by proteolytic cleavage in the extracellular amino-terminal domain and are thus termed proteinase-activated receptors (PARs). LÄS MER

5. 4. On the Causal Mechanisms of Stuttering

   Författare :Per A Alm; Lund Neurologi; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; stuttering; neurofysiologi; neuropsykologi; neurophysiology; Neurologi; dystonia; neuropsychology; Neurology; basal ganglia;

   Sammanfattning : Stuttering is one of the most common speech disorders. However, the etiology is poorly understood, and is likely to be heterogeneous. The aim of this thesis was to clarify causal mechanisms, focusing the brain. LÄS MER

7. 5. EMG and strength in trunk and hip muscles

   Författare :Eva A Andersson; Alf Thorstensson; Margareta Nordin; Eva A. Andersson; Gymnastik- och idrottshögskolan; Karolinska Institutet; []
   Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurophysiology; Neurofysiologi; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; abdominal muscles; biomechanics; electromyography; erector spinae; iliacus; iliopsoas; hip flexor muscles; locomotion; motor control; normalization; posture; psoas; quadratus lumborum; rehabilitation; running; sit-ups; strength; training exercises; u;

   Sammanfattning : The overall aim of this thesis was to study the myouelectric activity of all major muscles involved in the movements and stabilization of the trunk, pelvis and hips during training exercises, postures, motor tasks, maximal strength performance and locomotion. By use of ultra-sound, EMG electrodes could be guided safely and accurately into muscles situated even close to the spinal column, such as psoas, quadratus lumborum and deep parts of erector spinae.
