2. 21. 4D flow MRI and modelling to assess cerebral arterial hemodynamics : method development and evaluation, with implementation in patients with symptomatic carotid stenosis

   Author : Madelene Holmgren; Anders Eklund; Jan Malm; Anders Wåhlin; Sara Qvarlander; Ronnie Wirestam; Umeå universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; 4D flow MRI; carotid stenosis; cerebral blood flow; cerebral arterial compliance; cerebrovascular resistance; circleof Willis; computational fluid dynamics; magnetic resonance imaging; stroke; vascular disease; Neurology; neurologi;

   Abstract : Blood flow measurements are important for understanding the development of cerebrovascular diseases. With 4D flow magnetic resonance imaging (4D flow MRI), simultaneous velocity measurements are obtained in all cerebral arteries in a scan of about ten minutes. However, 4D flow MRI is a relatively new technique. READ MORE

4. 22. Methodological aspects on carotid artery intervention

   Author : Magnus Jonsson; Karolinska Institutet; Karolinska Institutet; []
   Keywords : carotid artery stenosis;

   Abstract : In Sweden, approximately 25000 patients suffer a cerebral infarction (stroke) annually. Stroke ranks as the third-leading cause of death, and is the leading cause of functional impairment. Carotid artery stenosis accounts for approximately 15% of all strokes and almost all of these are theoretically preventable. READ MORE

5. 23. Hereditary risk factors for stroke in humans - Association studies with emphasis on familial and genotypic factors

   Author : Håkan Lövkvist; Lund Neurologi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; allelic association; candidate genes; case-control; family history; ischemic stroke; polymorphisms.;

   Abstract : Background Stroke is a serious vascular disorder that comprises intracerebral hemorrhages, subarachnoid hemorrhages and ischemic stroke (IS). The etiology of stroke, including hereditary components induced by cellular mechanisms, is therefore a research field of vital importance. READ MORE

6. 24. Detection of paroxysmal atrial fibrillation : with special emphasis on intermittent ECG recording

   Author : Peter Doliwa; Karolinska Institutet; Karolinska Institutet; []
   Keywords : ;

   Abstract : Atrial fibrillation (AF) is the most common sustained form of arrhythmia, affecting approximately 3 % of the adult population. AF may be symptomatic or asymptomatic. Asymptomatic paroxysmal atrial fibrillation (PAF) can be troublesome to diagnose, as most devices for arrhythmia detection provide only limited insight into heart rhythm. READ MORE

7. 25. Retinal Transplants: Growth Differentiation Integration Organization and Survival

   Author : Rajesh Kumar Sharma; Lund Oftalmologi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; retinal degeneration; Retinal transplants; retinal development; treatment; connections; proliferation; survival; Ophtalmology; Oftalmologi;

   Abstract : The goal of the study was to get a better understanding of factors controlling the growth, differen-tia-tion, integration, organization and survival of retinal transplants, with the long-term view of eventually developing retinal transplantation into a clinically useful procedure for treating degenerative retinal disorders such as retinitis pigmentosa. Embryonic day 15 rabbit retinas were transplanted into adult rabbit eyes and were allowed to survive for various times. READ MORE
