Microvascular Research, 1973
A previous theoretical study on blood flow in capillaries has been extended and improved. The theory neglects the cell membrane's resistance to bending and uses the simplifications of the hydrodynamic theory of lubrication. Cell shape, cell velocity, pressure drop, and flow field are determined from the theory without recourse to empirical parameters.

Cochlear blood flow in the guinea pig was investigated using Tracer Sephadex 15 microspheres labelled with radioactive nuclides. A reference organ technique was used for quantitative measurements of cardiac output and the blood flow in the cochlear soft tissue, CNS and kidney.

Journal of Biomechanics, 1971
Abstract In this paper the theory of micropolar fluids with stretch is used to analyze blood flow in comparatively small arteries, say 100 μ dia. Physically micropolar fluids with stretch can provide a mathematical model to represent blood with its deformable substructure, since not only the independent rotation of red cells but also the flexibility ...

Glaucoma, one of the leading causes of blindness in the world, is characterized by progressive visual field loss and distinctive excavation of the optic nerve head. Although elevated intraocular pressure is the major risk factor, there is increasing evidence that the pathogenesis of glaucoma is also linked to altered ocular blood flow.

Pediatrics, 1982
In the commentary, "Pulsatility Index, Patent Ductus Arteriosus, and Brain Damage," It was stated that we have shown that "blood flow" to the brain was not reduced in premature lambs with left-right ductal shunting. The abstracted data referred primarily to alteration of the percent distribution of blood flow and not to changes of absolute blood flow ...

In summary, the vascular bed of the stomach is an area of great potential importance to both gastric and vascular physiologists. There are available many technics for its investigation. Simultaneous study of both hemodynamic and secretory phenomena can be conducted on the stomach.

European Radiology, 2001
Traditionally, Doppler ultrasound has been used to estimate blood flow as the mean velocity multiplied by the vessel area, but this is subject to significant errors and may be difficult to perform accurately. Microbubbles, developed as contrast agents for ultrasound, were initially envisaged as useful for increasing the intensity of echoes and thus ...

The Flow of Blood in the Capillaries
Physics in Medicine & Biology, 1968A model consisting of right circular cylinders moving through a tube is chosen to represent the flow of corpuscles through the capillaries. A numerical solution of the equations of motion enables the flow to be considered in detail. The pressure gradient-volume flux relationships are calculated for different values of the parameters of the system. Flow
