BACKGROUND Ultrasound is as a noninvasive method commonly used in the work-up of thyroid nodules. This study aimed to evaluate the usefulness of sonographic and elastosonographic parameters in the discrimination of malignancy. PATIENTS AND METHODS 150 thyroid nodules were evaluated by gray-scale, Doppler and elastosonography. The cytological analysis(More)
In the current study, the flame retardant wood-plastic composites (WPC) were produced by reducing the flammability of both the wood flour (WF) and the matrix material. Accordingly, WF was treated either with bis[tetrakis (hydroxymethyl) phosphonium] sulfate (THPS) or with dicyandiamide-formaldehyde-phosphoric acid flame retardants (DFP). The synergistic(More)
BACKGROUND/AIMS Nonalcoholic fatty liver disease (NAFLD) is currently the most common chronic liver disease worldwide. Along with the increase in the incidence of NAFLD and associated obesity, an increase in gallbladder disease (GD) has been noted. This has led to the identification of a new disease entity called fatty GD. There is a gap in the literature(More)
BACKGROUND AND OBJECTIVES Non-dipper hypertension is frequently accompanied by endothelial dysfunction and activation. Previous studies suggested that endocan may be a novel endothelial dysfunction marker. This study aims to investigate the association between circadian blood pressure (BP) pattern and plasma endocan levels together with high-sensitivity(More)
To the Editor We read the article " Effect of transcatheter aortic valve implantation on QT dispersion in patients with aortic stenosis " by Erkan, et al. [1] with great interest. In this study, they investigated the effect of transcatheter aortic valve implanta-tion (TAVI) on QT dispersion (QTd) in patients with symptomatic severe aortic stenosis. They(More)
Treatment of a central venous catheter emboli that has been asymptomatic for a number of years is controversial. A 56-year-old male patient who had an operation for sinus Valsalva aneurism rupture 22 years ago was referred to cardiology department for routine control. He had a mass inside the right heart on echocardiographic examination, and computed(More)
Poly(N-(hydroxymethyl)methacrylamide)-1-allyl-2-thiourea) hydrogels, poly(NHMMA-ATU), were synthesized by gamma radiation using (60)Co gamma source in the ternary mixture of NHMMA-ATU-H(2)O. These hydrogels were used for the specific gold, silver, platinum and palladium recovery, pre-concentration and matrix elimination from the solutions containing trace(More)
