OBJECTIVE The ideal small-caliber arterial graft remains elusive despite several decades of intense research. A novel approach to the development of small-caliber arterial prostheses with a biomimetic system for in vitro vessel culture has recently been described. In this study we examined the effects of culture time and tissue culture scaffolding on engineered vessel morphology and function an...

PURPOSE Christmas tree cataract consists of highly refractile multicolored "needles" crisscrossing the lens fibers of the deep cortex. The fact that the colors vary according to the angle of the incident light, and that in retroillumination only a dim outline of the cataract is seen, would suggest that Christmas tree cataract is a diffractive phenomenon. This study was performed to unravel the ...

OBJECTIVE To determine the morphological and functional changes in the right ventricle in pulmonary atresia with intact ventricular septum (PAIVS) for assessing the candidates for the different therapeutic procedures currently available. METHODS Thirty-one patients underwent cineangiocardiographic study with axial projections. Their ages ranged from 1 to 50 days (x = 9.6), and 28 of them were...

BACKGROUND AND PURPOSE Several recent prospective studies have found that unruptured intracranial aneurysms at various anatomic locations have different propensities for future rupture. This study aims to uncover the lack of understanding regarding rupture-prone characteristics, such as morphology and hemodynamic factors, associated with different intracranial aneurysm location. MATERIALS AND...

BACKGROUND Gastric epithelial dysplasia (GED) can be morphologically categorized into adenomatous and foveolar types. To date, there have been few studies on the clinical characteristics of GEDs according to the morphologic types. Therefore, we here aimed to elucidate the clinicopathologic characteristics of patients with GED and the long-term follow-up results after endoscopic resection accord...

Our proficiency in integrating imaging techniques that illustrate both the morphologic and physiologic characteristics of the brain is paramount and is a currently evolving strategy for daily clinical practice at some academic institutions. This combination of information gained from diffusion tensor imaging and several MR imaging techniques that depict the physiologic behavior of the brain, in...

the endocarp of celtis australis l. with hyrcanian forests of northern iran and arid mountains of northern africa ecotypes were studied considering macro and micro morphologic characteristics, using binocular and scanning electron microscope. the aim of this research was to evaluate the endocarp diversity in different ecological conditions. the results showed that celtis australis l. is bigger,...

OBJECTIVE The study was undertaken to identify the morphologic changes in the levator ani in different grades of prolapse by using reconstructed three-dimensional models of magnetic resonance images (MRI) and to subclassify prolapse into different categories on the basis of their levator ani morphologic characteristics. STUDY DESIGN Sixty-one women were studied, 8 women in stage I, 15 women i...
