ultrasound is one of the preferred modalities for evaluation of the parathyroid glands. this study was undertaken to determine the accuracy of high resolution ultrasound for secondary hyperparathyroidism in patients with chronic renal failure. from march 2008 to march 2009, ninety-one hemodialysis patients were examined by high resolution ultrasound (14 mhz) of the parathyroid glands in compari...

myelodysplastic syndromes (mdss) are a clonal bone marrow (bm) disease characterized by ineffective hematopoiesis, dysplastic maturation and progression to acute myeloid leukemia (aml). methylation silencing of hrk has been found in several human malignancies. in this study, we explored the association of hrk methylation status with its expression, clinical parameters and mds subtypes in mds pa...

in the research, six degrees of freedom hexapod parallel machine tool is studied and investigated. jacobian matrix is developed by cinematic relations differentiation and using weighted coefficient method, dimensional analysis operation is carried out on jacobian matrix. geometric parameters of cartesian robot workspace are optimized, considering a minimum allowable rotation about three axes, a...

a 53-year-old male was referred to our department for refractory primary hypertension. despite high doses of 6 anti-hypertensive drugs, ambulatory monitoring of blood pressure (bp) revealed a mean bp of 160/90 mmhg. under local anaesthesia, renal denervation with radiofrequency was performed supported by high-resolution 3d angiography, which helped confirm the position of the applications in a ...

as the information carried in a high spatial resolution image is not represented by single pixels but by meaningful image objects, which include the association of multiple pixels and their mutual relations, the object based method has become one of the most commonly used strategies for the processing of high resolution imagery. this processing comprises two fundamental and critical steps towar...

Super-resolution (SR) aims to overcome the ill-posed conditions of image acquisition. SR facilitates scene recognition from low-resolution image(s). Generally assumes that high and low resolution images share similar intrinsic geometries. Various approaches have tried to aggregate the informative details of multiple low-resolution images into a high-resolution one. In this paper, we present a n...

the purpose of velocity analysis is to extract the normal moveout velocity as a function of the zero-offset travel time at selected cdp locations along the seismic line. since results of velocity analysis depend on coherency estimator, an estimator that provides a high velocity resolution is essential. even though the conventional semblance method which is the most popular coherency estimator (...
