Biosensing of Haemorheological Properties Using Microblood Flow Manipulation and Quantification

open access: yesSensors, 2022
The biomechanical properties of blood have been used to detect haematological diseases and disorders. The simultaneous measurement of multiple haemorheological properties has been considered an important aspect for separating the individual contributions

Thixotropic effect of some biochemical factors in ischaemic stroke

open access: yesJournal of Medical Science, 2018
Background. Yield shear stress (YSS) well characterizes the thixotropic status of blood, that exemplifies a reversible loss of blood fluidity due to a low shear rate. At the stable haematocrit ratio YSS depends mainly on the fibrinogen level. Aim.

Blood rheology, cardiovascular risk factors, and cardiovascular disease: The West of Scotland Coronary Prevention Study [PDF]

open access: yes, 2000
The West of Scotland Coronary Prevention Study (WOSCOPS) showed that pravastatin reduced the risk of coronary heart disease (CHD) events in 6,595 middle-aged hypercholesterolaemic men aged 45-64 years without prior myocardial infarction followed for an ...

Prolonged elevations in haemostatic and rheological responses following psychological stress in low socioeconomic status men and women [PDF]

open access: yes, 2003
Low socioeconomic status (SES) and psychological stress are associated with increased risk of coronary heart disease, and both may influence haemostatic responses.

Blood viscosity after splenectomy. [PDF]

open access: yesBMJ, 1981
Blood viscosity and its contributory factors--namely, plasma viscosity, fibrinogen concentration, packed cell volume, red-cell deformability, and platelet count--were measured in 20 asymptomatic patients after splenectomy and compared with those in controls.

The effect of physical activity on structural and functional arterial adaptations in humans: a narrative review [PDF]

open access: yesفصلنامه ابن سینا, 2022
Background and aims: Aerobic exercise and high-intensity interval training reduce arterial stiffness, while resistance training does not increase or alter arterial stiffness. However, the molecular mechanism of these effects in different training methods

Blood Rheology: Key Parameters, Impact on Blood Flow, Role in Sickle Cell Disease and Effects of Exercise

open access: yesFrontiers in Physiology, 2019
Blood viscosity is an important determinant of local flow characteristics, which exhibits shear thinning behavior: it decreases exponentially with increasing shear rates. Both hematocrit and plasma viscosity influence blood viscosity.

Does sticky blood predict a sticky end? Associations of blood viscosity, haematocrit and fibrinogen with mortality in the West of Scotland [PDF]

open access: yes, 2003
There is increasing evidence that blood viscosity and its major determinants (haematocrit, plasma viscosity and fibrinogen) are associated with an increased risk of incident cardiovascular events; however, their associations with mortality are not ...

Ultrasound Standing Wave-Based Cell-to-liquid Separation for Measuring Viscosity and Aggregation of Blood Sample

open access: yesSensors, 2020
When quantifying mechanical properties of blood samples flowing in closed fluidic circuits, blood samples are collected at specific intervals. Centrifugal separation is considered as a required procedure for preparing blood samples.

Murray's law revisited: Qu\'emada's fluid model and fractal trees [PDF]

open access: yes, 2015
In 1926, Murray proposed the first law for the optimal design of blood vessels. He minimized the power dissipation arising from the trade-off between fluid circulation and blood maintenance.
