It was shown in [1] that in the presence of the magnetic field the sound waves in (2+1) dimensional plasma disappear and are replaces by a diffusive mode. Similarly, the shear and charge diffusion fluctuations form a subdiffusive mode. However, since the limit of small magnetic field does not commute with the hydrodynamic limit it is not obvious whether or not these modes are stable under highe...

Six hours of mild surface cooling in moving air at 24 degrees C with little fall in core temperature (0.4 degree C) increased the packed cell volume by 7% and increased the platelet count and usually the mean platelet volume to produce a 15% increase in the fraction of plasma volume occupied by platelets. Little of these increases occurred in the first hour. Whole blood viscosity increased by 2...

The association between hypergammaglobulinaemia and raised serum viscosity has been recognised for more than 40 years. Waldenstrom (1944) described three patients in whom macroglobulinaemia was associated with increased serum viscosity, and even earlier than this there had been reports of raised plasma viscosity in myelomatosis (Albers, 1937). Since these early reports many of the clinical feat...

1. Blood rheology has been quantified by measuring blood and plasma viscosity, packed cell volume (PCV), erythrocyte filterability and erythrocyte aggregation in forty-eight voluntary vegetarians and compared with matched controls. 2. Results show that in vegetarians, values for PCV were lower than those in controls, leading to reduced native blood viscosity. In addition PCV-standardized blood ...

BACKGROUND Abnormalities in blood rheology may be factors contributing to cardiovascular complications and the progression of renal failure in kidney allograft recipients. The haemorheological variables haematocrit, fibrinogen, whole blood viscosity, plasma viscosity, erythrocyte aggregation tendency and fluidity were measured in 27 cyclosporin A (CyA)-treated patients who had received a renal ...

The effect of transfusing a nonextravasating, zero-link polymer of cell-free hemoglobin on pial arteriolar diameter, cerebral blood flow (CBF), and O2 transport (CBF x arterial O2 content) was compared with that of transfusing an albumin solution at equivalent reductions in hematocrit (approximately 19%) in anesthetized cats. The influence of viscosity was assessed by coinfusion of a high-visco...

Recent hexadecapole (v4) and elliptic (v2) flow measurements are used to constrain estimates for the degree of local equilibrium, mean free path λ, and the viscosity to entropy density ratio (ηs ) of the plasma produced in Au+Au collisions at √ sNN = 200 GeV. The eccentricity-scaled flow coefficients v2 ε2 and v4 ε4 indicate that the plasma achieves a degree of local equilibrium within ∼ 5 − 10...

Background. Increased blood and plasma viscosity, hematocrit, fibrinogen, and activation of coagulation and leukocytes have been reported in patients with claudication; however, their associations with symptomatic and asymptomatic peripheral arterial disease have not been reported in an epidemiological study. Methods and Results. Blood and plasma viscosity, hematocrit, fibrinogen, urinary fibri...

To assess whether the rheological properties of blood might be altered by exercise, we measured whole blood viscosity, plasma viscosity, and its components in healthy female subjects before, immediately after, and 1 h after maximal upright exercise using the Bruce graded exercise protocol. Forty-seven female subjects (15 sedentary, 14 who ran 5-15 miles/wk, and 18 who ran greater than 50 miles/...

We investigated 100 consecutive cerebral ischemia patients for hemorheological alterations. We measured whole and adjusted blood viscosity at 75 and 1,500 sec-1, plasma viscosity, red blood cell aggregation by the zeta sedimentation ratio, and red blood cell deformability using the centrifugal deformability technique. Patients were studied within 72 hours of the acute ischemic event, and 66 wer...
