2. 16. Laser Doppler Flowmetry and Imaging: Methodological Studies

   Author : Siv Bornmyr; Malmö Institutionen för kliniska vetenskaper; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Clinical physics; digital photography.; cold intolerance; sympathetic nervous system; flow cessation external pressure; skin temperature; thermography; skin blood flow; laser doppler imaging; Laser doppler flowmetry; radiology; tomography; medical instrumentation; Klinisk fysiologi; radiologi; tomografi; medicinsk instrumentering;

   Abstract : Laser Doppler flowmetry (LDF) and laser Doppler imaging (LDI) are modern methods for non-invasive and continuous assessment of skin blood flow. The techniques are based on the phenomenon that monochromatic light transilluminating a perfused tissue is spectrally broadened owing to scattering by moving blood cells. READ MORE

4. 17. Studies on the regulation of human skeletal muscle lipolysis in vivo

   Author : Veronica Quisth; Karolinska Institutet; Karolinska Institutet; []
   Keywords : Intramuscular triglycerides; skeletal muscle; lipolysis; insulin; catecholamines; microdialysis;

   Abstract : Intramuscular triglyceride deposits are a significant energy source, and are considered to be of importance in the pathogenesis of skeletal muscle insulin resistance. In contrast to adipose tissue, the lipolytic process in skeletal muscle is not well characterised. READ MORE

5. 18. Renal hemodynamics in renal artery stenosis and angiotensin II-dependent hypertension. Pathophysiological and diagnostic aspects

   Author : Aso Saeed; Göteborgs universitet; []
   Keywords : angiotensin II; autoregulation of renal blood flow; color duplex sonography; endothelin-1; oxidative stress; renal artery stenosis; renal hemodynamics; renovascular hypertension;

   Abstract : Patients with renovascular hypertension have a poor renal and cardiovascular prognosis. To improve the care of these patients, we need to increase knowledge about the pathophysiological mechanisms involved. READ MORE

6. 19. Optical Monitoring of Cerebral Microcirculation

   Author : Peter Rejmstad; Karin Wårdell; Göran Salerud; Neda Haj-Hosseini; Kerstin Ramser; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; optical monitoring; cerebral microcirculation; diffuse reflectance spectroswcopy DRS ; laser Doppler flowmetry LDF ;

   Abstract : The cerebral microcirculation consists of a complex network of small blood vessels that support nerve cells with oxygen and nutrition. The blood flow and oxygen delivery in the microcirculatory blood vessels are regulated through mechanisms which may be influenced or impaired by disease or brain damage resulting from conditions such as brain tumors, traumatic brain injury or subarachnoid hemorrhage (SAH).

7. 20. Early Physiotherapy in the Neurointensive Care Unit - Passive Physiotherapy Interventions

   Author : Annelie Thelandersson; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physiotherapy; Brain injury; Stroke; Intensive care unit; Prone position; Range of motion; Continuous passive motion; Intra cranial pressure; Cerebral perfuison pressure; Haemodynamics;

   Abstract : Background: In critically ill patients, treated in the neurointensive care unit (NICU) because of severe brain injury or stroke, physical activities have been restricted to a minimum due to the potential risks of complications and adverse events. Nevertheless, passive physiotherapy treatments are widely used without conclusive evidence for their safety. READ MORE
