The authors review (1) the range of techniques used to study the retinal vasculature near the fovea, (2) describe the need and rationale for noninvasive in vivo monitoring of the retinal vasculature, (3) present theoretic and practical considerations which show that entoptic visualization of the smallest capillaries near the fovea is optimized by a small short-wavelength source (1 mm or less) r...

The purpose of this work is to numerically evaluate the behavior microscopic gas-focused liquid sheets in terms material properties, nozzle structure and operating conditions used for experiments spectroscopy scattering where a short optical path required. numerical simulations are presented gas flow focusing nozzle, capable producing stream consisting sequence perpendicular micrometre thin she...

Horseradish peroxidase (mol. diam. approximately 50 A) and ferritin (mol. diam. approximately 110 A) were used as probe molecules for the small and large pore system, respectively, in blood capillaries of the intestinal mucosa of the mouse. Peroxidase distribution was followed in time, after intravenous injection, by applying the Graham-Karnovsky histochemical procedure to aldehyde-fixed specim...

The capillary bundle model, wherein the flow dynamics of a porous medium is predicted from that independent cylindrical tubes/capillaries whose radii are distributed according to medium's pore size distribution, has been used extensively. However, as it lacks an interaction between channels, this model fails at predicting complex configuration, including those involving two-phase flow. We propo...

Background: Neuropathy is one of the important complications of diabetes. Deficiency of the nerve conduction velocity (NCV) that occurs in both human diabetic neuropathy and animal diabetes models is one of the indicators for diabetic neuropathy. In the present study, we examined the effect of enalapril, angiotensinconverting enzyme inhibitor on NCV, number of endoneurial capillaries and th...
