This study has been performed to demonstrate the type and frequency of the anatomical variations of the sacroiliac joint according to age, gender, Body Mass Index and childbirth, and the influence of the anatomical variants to the uniformity and width of the joint space. It was conducted on 400 consecutive patients without sacroiliac complaint who underwent pelvic CT scanning for various reason...

OBJECTIVE To investigate the relationships between the apparent diffusion coefficients (ADCs) on diffusion-weighted imaging (DWI) and the speed of contrast-enhancement in hepatic hemangiomas. MATERIALS AND METHODS Sixty-nine hepatic hemangiomas (≥ 1 cm) were evaluated with DWI, by using multiple b values (b = 50, 400, 800 s/mm(2)), followed by a gadolinium-enhanced dynamic MRI. The lesions we...

OBJECTIVE Evaluation of the efficacy and safety of a single oral dose of a 1200 mg sachet of chondroitin 4&6 sulfate (CS 1200) vs three daily capsules of chondroitin 4&6 sulfate 400 mg (CS 3*400) (equivalence study) and vs placebo (superiority study) during 3 months, in patients with knee osteoarthritis (OA). DESIGN Comparative, double-blind, randomized, multicenter study, including 353 patie...

Short-term lower leg growth was investigated with twice weekly knemometry measurements in 19 schoolchildren with mild asthma during treatment with daily doses of 200 micrograms fluticasone propionate, 400 micrograms, and 800 micrograms beclomethasone dipropionate from a dry powder inhaler. The design was a randomised, double blind, crossover trial. After a run in period of four days (period 1) ...

We demonstrate passive large-scale nanophotonic phased arrays in a CMOS-compatible silicon photonic platform. Silicon nitride waveguides are used to allow for higher input power and lower phase variation compared to a silicon-based distribution network. A phased array at an infrared wavelength of 1550 nm is demonstrated with an ultra-large aperture size of 4  mm×4  mm, achieving a record small ...

BACKGROUND Many hypertensive patients require combination therapy to achieve target blood pressure (BP). beta-Blockers and dihydropyridine calcium channel blockers are effective as monotherapy in hypertensive patients and have complementary mechanisms for lowering BP. METHODS This multicenter, randomized, placebo-controlled, unbalanced factorial study included a 4- to 5-week single-blind plac...

In this study, SHS was used to produce metal-intermetallic-ceramic laminate AlMg6-NiAl-TiC composite. The experiment conducted without a cylindrical powder pellet holder produced no joint between the NiAl and AlMg6 sheet. On other hand, inside (CPPH) with blind hole joint. It found that sheet had temperature of 400–550 °C across its entire thickness during SHS. study microstructure energy-dispe...
