Total hip replacement for high dislocation of the hip joint remains technically difficult in terms of preparation of the true acetabulum and restoration of leg length. We describe our experience of cementless total hip replacement combined with a subtrochanteric femoral shortening osteotomy in 20 hips with Crowe grade IV dislocation with a mean follow-up of 8.1 years (4 to 11.5). There was one ...

Endothelial function is known to be impaired in essential hypertensive patients. In this study, we examined whether antihypertensive drugs improve forearm vasodilatory response to reactive hyperemia in 26 patients with essential hypertension (62 +/- 2 years) without diabetes mellitus, hyperlipidemia, coronary heart disease, or cerebrovascular disease. Antihypertensive drugs were never given or ...

Middle to upper tropospheric humidity plays a large role in determining terrestrial outgoing longwave radiation. Much work has gone into improving the accuracy of humidity measurements made by radiosondes. Some radiosonde humidity sensors experience a dry bias caused by solar heating. During the austral summers of 2002/03 and 2003/04 at Dome C, Antarctica, Vaisala RS90 radiosondes were launched...

operating field impaired access to the patients. The radial pulse always disappeared before the femoral pulse, which always disappeared before the carotid pulse. The data were split into four subgroups: radial, femoral, and carotid pulses present (group 1), femoral and carotid pulses only (group 2), carotid pulse only (group 3), and radial, femoral, and carotid pulses absent (group 4). The figu...

A new analytical method based on vortex-assisted liquid-liquid microextraction with back extraction (VALLME-BE) coupled high performance liquid chromatography was developed for the simultaneous determination of antidiabetic drugs; repaglinide, glibenclamide, and glimepiride in water samples. Chromatographic separation achieved using C18 column (250 × 4.6 mm 5 µm) methanol-phosphate buffer (pH3....

sialolithiasis is a common disease of the major salivary glands, characterized by the obstruction of a salivary gland or its excretory duct due to the formation of calcareous concretions. sialoliths usually measure from 1 mm to <10 mm. they rarely measure more than 15 mm, and infrequently giant salivary gland calculi >15 mm have been reported in the literature. the submandibular gland and its d...

The main aim of this study was to evaluate the effects of silicon (Si), ethanol (Et), ascorbic acid (AA) and citric acid (CA) on vase life of Narcissus tazetta L. cv. ‘Shahla’cut flowers. For this purpose, an experiment based on completely randomized design was conducted with Si (5, 10 and 20 mM), Et (2 and 4%), AA (100, 200 and 300 mg L-1), CA (100, 200 and 300 mg L-1) and control (distillated...
