In the present work a two fluid model for blood flow through abnormally constrictedhuman artery (stenosed artery) has been developed. The model consists of a core region of suspensionof all erythrocytes assumed to be micro-polar fluid so as to include the micro-structural effects inaddition to the peripheral-layer viscosity effects, and a peripheral plasma layer free from cells of anykind of Ne...

Calcifying odontogenic cyst (COC) is an odontogenic cyst with accumulation of ghost cells that has central and peripheral subsets. Here, we present an 11-year-old male patient with an intraoral swelling on the left posterior mandibular ridge interfering with eruption of the second molar. Histopathologic examination revealed a cystic lesion lined by ameloblast-like epithelium in the basal layer ...

OBJECTIVES Fibrin glue in combination with polyglycolic acid (PGA) mesh is effective in preventing air leakage after segmentectomy, but we frequently experienced air leakage with single-layer application. To investigate improved usage, we compared the sealing effect among single-, double- and triple-layer PGA mesh and fibrin glue in both experimental and clinical segmentectomy. METHODS Ex viv...

The aim of the study was to evaluate the effect of sex and age on the thickness of the retinal layer in normal eyes using spectral-domain optical coherence tomography (SD-OCT).Fifty healthy subjects between the ages of 20 and 80 had their retinal layers measured using SD-OCT at Seoul St. Mary's Hospital. Mean thickness and volume were measured for 9 retinal layers in the fovea, the pericentral ...

Central and peripheral benzodiazepine receptors were localized in the rat, monkey, and human eye by in vitro autoradiography. Central benzodiazepine binding sites, visualized with 3H-R015-1788, were enriched in the inner plexiform layer in all three species. Binding sites also were present in the nerve fiber layer, the ganglion cell layer, and in portions of the inner nuclear layer. Peripheral ...

The goal of this investigation is to study the three layered (core layer, intermediate layer, and peripheral layer) tubular flow of power law fluids with variable viscosity by peristalsis in order to investigate the strength of the role played by an artificially generated intermediate layer to ease constipation. The solution is carried out under the long wavelength and low Reynolds number appro...

Background & Aims: Amniotic membrane persists for a long time after ocular transplantation (as corneal substitute) and can affect light transmission (transparency). The aim of this study was to evaluate the transparency of amniotic membrane after freeze-drying (lyophilization) and to compare the results with transparency of rabbit cornea. Methods: Transparency of rabbits’ corneas and fresh and ...
