The specimen consisted of a placenta with the attached portion of the cord of the normal foetus towards one pole. The umbilical vessels of this cord traversed the placenta and were continuous with another shrivelled-up cord 6 cm. long hooded by a globular mass 6-8 cm. in diameter clothed with skin containing sparse hair. No definite structures were made out externally (Fig. i, overleaf). The cu...

In just three years since its first introduction,',' the oxide-confined VCSEL has come to dominate much of the semiconductor laser research e f f ~ r t . ~ ~ Its prominence in studies of semiconductor microcavity physics is expected to increase as well, as it represents a promising means of minimizing an optical mode volume. The ease of processing allows novel forms of two-dimensional arrays, a...

The concept of the study was to find the correlation between the morphometry of the suprascapular notch and basic anthropometric measurements of the human scapula. The measurements of the human scapulae included: morphological length and width, maximal width and length projection of scapular spine, length of acromion, and maximal length of the coracoid process. The glenoid cavity was measured i...

A porous hydroxyapatite/collagen composite (HAp/Col) was developed that consists of hydroxyapatite nanocrystals and atelocollagen. In this study, cylindrical (diameter: 5 mm, height: 3 mm) porous HAp/Col implants with different pore sizes (diameter: 160 or 290 microm) were prepared, and the influences of pore size and implanted volume were evaluated using a rabbit bone defect model. In the impl...

AIM To comparatively evaluate Seldinger and Trocar techniques in the percutaneous treatment of hydatid disease. METHODS Trocar and Seldinger techniques were used for 49 and 56 cysts, respectively, among 106 hydatid cysts in 88 patients. The number of males and females were 22 and 66, respectively with a mean age of 44.9 years (range, 15-87). Follow-up studies included cyst diameter, cyst cont...

PURPOSE To determine the effect of pelvic arch interference and the depth of the pelvic cavity, as shown on preoperative magnetic resonance imaging (MRI), on the performance of extraperitoneal laparoscopic radical prostatectomy (ELRP). MATERIALS AND METHODS In 115 patients, pelvic bone images were obtained at the time of prostate MRI before ELRP. In the reconstructed sagittal plane, we measur...

OBJECTIVE Surgery and percutaneous aspiration-injection-re-aspiration (PAIR) are widely accepted treatment modalities for hepatic hydatid cysts. Endoscopic retrograde cholangiopancreaticography (ERCP) acts as a minimally invasive rescue method for the biliary complications of both the hydatid cysts and treatment modalities. The aim of this study was to identify the role of different treatment m...

rootcollar diameter as the standard, nondestructive measure of seedling quality. Other nondestructive measures of seedling quality would be valuable. One option, root-bound index (RBI), reflects the ratio of rootcollar and cavity diameters (South et al. 2005, South and Mitchell 2006). This variable is an indirect, nondestructive measure of how well the cavity accommodates both the taproot and f...
