1. 1. Blood Flow variations in Large Arteries due to non-Newtonian rheology

   Författare :Stevin van Wyk; Laszlo Fuchs; Staffan Lundström; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Blood; Rheology; Viscosity; non-Newtonian; CFD; Bifurcations; Unsteadiness; Wall Shear Stress; Atherosclerosis;

   Sammanfattning : The blood is a complex fluid that contains, in addition to water, cells, macro-molecules and a large number of smaller molecules. The physical properties of the blood are therefore the result of non-linear interactions of its constituents, which are influenced by the local flow field conditions. LÄS MER

4. 3. Effects of Hemoglobin Normalization with Epoetin in Chronic Kidney Disease

   Författare :Hans Furuland; Björn Wikström; Torbjörn Linde; Peter Barany; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Internal medicine; Anemia; blood viscosity; cardiac output; chronic kidney disease; renal dialysis; dialysis adequacy; erythopoietin; heart rate variability; hemoglobin; hemorheology; hypertension; kidney transplantation; Kt V; left ventricular hypertrophy; Quality of Life; Invärtesmedicin; Internal medicine; Invärtesmedicin;

   Sammanfattning : Anemia is common in patients with chronic kidney disease (CDK), contributes to reduced Quality of Life (QoL) and is associated with cardiovascular disease, morbidity and mortality. Epoetin raises hemoglobin (Hb) and increases QoL and physical exercise capacity. LÄS MER

5. 4. Synthetic Paper for Point-of-Care Diagnostics : Capillary control, surface modifications, and their applications

   Författare :Weijin Guo; Wouter van der Wijngaart; Jonas Hansson; Govind V. Kaigala; KTH; []

   Sammanfattning : Capillary-based platforms for diagnostics are popular for the point-of-care diagnostics market because of their low cost, easy fabrication, and easy operation. Lateral flow tests are an excellent example of capillary-based platforms for point-of-care diagnostics. LÄS MER

7. 5. Stroke : patient characteristics, efficacy of a stroke unit and evaluation of hemodilution therapy

   Författare :Tage Strand; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Acute cerebrovascular disease; blood viscosity; cerebral infarction; hemodilution therapy; stroke unit;

   Sammanfattning : Stroke is a major health problem in all developed countries. These studies, performed in a stroke unit at a medical department, were designed to characterize essential clinical features of the different cerebrovascular disorders on admission to hospital, to evaluate the efficacy of admitting unselected stroke patients to a stroke unit and, to evaluate hemodilution as a therapeutical regime in patients with cerebral infarction.
