Viscosity

Viscosity

When water is poured into a glass, it falls freely and quickly, whereas if honey or maple syrup is poured over a pancake, it flows slowly and sticks to the surface of the container. This difference in the flow of different kinds of liquids arises due to the fluid friction between the liquid layers and the liquid and the surrounding material. This property of fluids is called fluid viscosity. In this example, water has a lower viscosity than honey and maple syrup.
The SI unit of viscosity is...

Surface Tension, Capillary Action, and Viscosity

Surface Tension, Capillary Action, and Viscosity

Surface Tension
The various IMFs between identical molecules of a substance are examples of cohesive forces. The molecules within a liquid are surrounded by other molecules and are attracted equally in all directions by the cohesive forces within the liquid. However, the molecules on the surface of a liquid are attracted only by about one-half as many molecules. Because of the unbalanced molecular attractions on the surface molecules, liquids contract to form a shape that minimizes the number...

Extrinsic and Intrinsic Pathways of Hemostasis

Extrinsic and Intrinsic Pathways of Hemostasis

Blood clotting or coagulation involves extrinsic and intrinsic pathways, which ultimately merge into the common pathway, forming a fibrin clot.
The Extrinsic Pathway
The extrinsic pathway of coagulation is typically initiated by tissue damage that exposes blood to tissue factor (TF), a protein released by the damaged tissue cells outside the blood vessels—this interaction with TF triggers biochemical reactions involving specific clotting factors. The key player here is Factor VII, which...

Viscosity of Fluid

Viscosity of Fluid

Viscosity measures the resistance a fluid offers to flow and deformation. It results from internal friction between layers of fluid moving relative to one another. Dynamic viscosity, denoted by the Greek letter mu (μ), quantifies the force needed to move one fluid layer over another. For Newtonian fluids like water and air, the relationship between the shearing stress and the rate of shearing strain is linear, meaning their viscosity remains constant regardless of the applied stress.

Summary

Whole blood viscosity, a measure of blood stasis, shows an inverse association with hemostasis indices. This suggests estimated whole blood viscosity (eWBV) could complement traditional hemostasis tests in clinical practice.

Area of Science:

Clinical Pathology
Hematology

Background:

Whole blood viscosity (WBV) is an underutilized parameter for assessing blood stasis.
Traditional hemostasis tests (coagulation profiles) have limitations including restricted laboratory access and long turnaround times.

Purpose of the Study:

To investigate the correlation between the index of stasis (estimated WBV) and standard indices of hemostasis.

Main Methods:

Observational research using archived pathology data from 193 patients.
Evaluated hemostasis indices: activated partial thromboplastin time (APTT), prothrombin time (PT), international normalization ratio (INR), and D-dimer.
Assessed blood stasis using estimated WBV (eWBV), hematocrit, and serum protein levels.

Main Results:

Hemostasis data were skewed, while eWBV and platelet counts were normally distributed.
Hemostasis indices showed a significant inverse association with eWBV (p < 0.001).
eWBV had a weak positive correlation with platelet count but a negligible negative correlation with PT and APTT.

Conclusions:

Despite limitations, hemostasis indices are inversely associated with eWBV.
eWBV may serve as an alternative or complementary test for evaluating hemostasis.
Further research, potentially normalizing skewed data, is needed to enhance correlation and clinical utility.
