Cerebral vasospasm after aneurysmal subarachnoid hemorrhage is a potentially severe sequel. The induction of hypertension, hypervolemia, and hemodilution is advocated for vasospasm, but it is unclear whether hemodilution confers any... more
In transport phenomena, precise knowledge or estimation of fluids properties is necessary, for mass flow and heat transfer computations. Viscosity is one of the important properties which are affected by pressure and temperature. In the... more
In arterial blood flow, the wall shear stress expresses the force per unit area exerted by the wall on the fluid in a direction on the local tangent plane. There is substantial evidence that the wall shear stress induced by the pulsatile... more
The association between testosterone-replacement therapy and cardiovascular risk remains unclear with most reports suggesting a neutral or possibly beneficial effect of the hormone in men and women. However, several cardiovascular... more
Spine surgery may be associated with profuse intraoperative bleeding that often requires blood transfusions. In recent years several techniques have been developed to avoid allogenic transfusions and their potential complications to... more
Background: Mechanisms that mediate cocaine- induced cardiovascular events following vasoconstric- tion are incompletely understood. Objective: To examine the effects of cocaine in mod- erate doses on hematologic and hemostatic parameters... more
The present study in female rats determined the effects of experimental hyperthyroidsm on hemorheological parameters and fibrinogen concentration. To induce experimental hyperthyroidism L-thyroxine (0.4 mg/100 g fodder) was added to the... more
In arterial blood flow, the wall shear stress expresses the force per unit area exerted by the wall on the fluid in a direction on the local tangent plane. There is substantial evidence that the wall shear stress induced by the pulsatile... more
Much evidence suggests that blood viscosity (BV) is involved in some pathological processes, such as myocardial ischemia, strokes, and cognitive deficits. In addition, there are data pointing to the higher BV in individuals with sleep... more
The study provides information on the blood fluidity in healthy, juvenile sheep and rabbits during growth (n = 18), and shows also data from fetal rabbits and cats. In the fetal rabbit (n = 3) and cat (n = 2), whole blood viscosity (WBV;... more
The aim of this study was to evaluate together the main hemorheologic parameters and one of the transmembrane ion transport systems in erythrocytes of subjects with normal and elevated blood pressure. Three sex-, age-, and weight-matched... more
The apparent viscosity of blood in glass tubes declines with decreasing diameter (Fåhraeus-Lindqvist effect) and exhibits a distinctive minimum at 6–7 μm. However, flow resistance in vivo in small vessels is substantially higher than... more
