Objectives There are inconsistent data about the association between saliva properties, dental caries, and periodontal status. In this study, we tried to examine the association between dental caries and periodontal status with salivary viscosity, flow rate, pH, and buffering capacity in adults. Methods In the present cross-sectional study, 450 female teachers were randomly selected from scho...

In 1940 T'ang and Wang (1) measured the erythrocyte sedimentation rate and the plasma viscosity in 176 cases of pulmonary tuberculosis and 56 cases of tuberculosis of other organs. These writers concluded from their data that the plasma viscosity determination may be a more sensitive test for activity of tuberculosis than the sedimentation rate. Independently, in 1942, Whittington (2) in a stud...

The TA-XT21 texture analyzer (TA) was used to evaluate vitelline membrane strength (VMS). Fresh and aged (1 wk at 25 C) eggs (n = 48 eggs x 2 replications) were evaluated. Fresh and aged eggs were further divided into two groups of yolk only or whole egg (with intact albumen). Yolk index, Haugh units, pH, broken-out egg weights, VMS, yolk viscosity, and scanning electron microscopy (SEM) images...

Due to the increasingly wide application of electroosmotic flow in micromachines, this paper investigates the electroosmotic flow of the power-law fluid under high zeta potential in a cylindrical microcapillary for different dimensionless parameters. The electric potential distribution inside a cylindrical microcapillary is presented by the complete Poisson-Boltzmann equation applicable to an a...

Foam viscosity is a key property to predict the foam flow in narrow channels and porous media. In this study, we investigated effects of quality temperature on dynamic how modifying composition colloidal system can alter rheology. It was shown that addition nanoparticles polymer improve stability at high-temperature conditions increase apparent viscosity. The results confirmed be predicted usin...

Disturbances of the microcirculation and abnormal hemorheological properties are important factors that play an important role in disseminated intravascular coagulation (DIC) and result in organ dysfunction or failure. In the present study, we established an animal model of DIC using intravenous Dextran 500 in rats, and used exogenous normal lymph corresponding to 1/15 of whole blood volume for...

Introduction: Reports concerning the association of physical activity with markers of inflammation, coagulation, and fibrinolysis are ambiguous. The aim of this study was to assess the effect of 4 weeks of combined decomposedsit-up and walking training with two different volumes onfibrinogen, plasma viscosity and insulin resistance index (HOMA-IR) in college, young men. Methods: In this semi...

Certain factors are common to the erythrocyte sedimentation rate and the plasma viscosity. Thus fibrinogen increases the erythrocyte sedimentation rate (Gram, 1921 ; Greisheimer, Johnson, and Ryan, 1929) and Hardwicke, Ricketts, and Squire (1950) found that a direct logarithmic relation exists between the erythrocyte sedimentation rate and the plasma fibrinogen concentration. Also fibrinogen ex...

BACKGROUND Recent evidence suggests that red blood cell aggregation and the ratio of hematocrit to blood viscosity (HVR), an index of the oxygen transport potential of blood, might considerably modulate blood flow dynamics in the microcirculation. It thus seems likely that these factors could play a role in sickle cell disease. DESIGN AND METHODS We compared red blood cell aggregation charact...

The convective heat transfer and pressure drop of water based Al2O3 nanofluid in a horizontal tube subject to constant wall temperature condition is investigated by computational fluid dynamic (CFD) method. The Al2O3 nanofluid at five volume concentration of 0.1, 0.5, 1.0, 1.5 and 2 % are applied as a non Newtonian power law and Newtonian fluid with experimentally measured properties of density...
