This study aimed to evaluate the Chagas Disease Control Program which has operated since 1982 in the municipality of Berilo in the Jequitinhonha Valley, Minas Gerais, Brazil, based on evaluation of 5,242 domiciliary units (DUs) and 7,807 outbuildings over an eight-year period of epidemiological surveillance implanted in 1997. A total of 391 triatomines (280 Panstrongylus megistus and 111 Triato...

D e s c r i p t i o n o f t e s t s a n d d i a g n o s t i c s t a n d a r d DUS, MRA, and DSA were done within 4 weeks. The degree of stenosis on DUS was based on the peak systolic velocity (PSV) in the proximal internal carotid artery; analysis of DUS was based on a threshold of 70% stenosis, represented by a PSV of 270 cm/s. DSA was the diagnostic standard: A positive test result was define...

The aim of this study was to compare diagnostic efficiency of excretory urography (EU), ultrasonography-guided percutaneous antegrade pyelography (UGPAP), and renal Doppler ultrasonography (DUS) in New Zealand rabbits (n= 20) experimentally induced unilateral partial ureteral obstruction. The resistive index (RI) value was obtained from all rabbits prior to the induction. A partial ureteral obs...

Carotid disease is a major cause of cerebrovascular events. Risk is proportional to the extent and severity of atherosclerosis. Aim of this study was to assess the correlation between 64-multi-detector-row computed-tomography angiography (MDCTA) and Doppler ultrasound peak-systolic-velocity (DUS-PSV) in the quantification of stenosis. 116 consecutive patients were included; it was calculated th...

The objective of this article is to provide scientists, engineers and clinicians with an up-to–date overview on the current state of development in the area of three-dimensional ultrasound (3-DUS) and to serve as a reference for individuals who wish to learn more about 3-DUS imaging. The sections will review the state of the art with respect to 3-DUS imaging, methods of data acquisition, analys...

The reduction of specific uridines to dihydrouridine is one of the most common modifications in tRNA. Increased levels of the dihydrouridine modification are associated with cancer. Dihydrouridine synthases (Dus) from different subfamilies selectively reduce distinct uridines, located at spatially unique positions of folded tRNA, into dihydrouridine. Because the catalytic center of all Dus enzy...

The incidence of varicose veins and the need for treatment has shown a tremendous increase over the years. Debilitating venous ulcers and dragging edemas of the lower limb with overall improvement in cosmetic results and availability of endovenous procedures has brought many patients forward for treatment. Continuous-wave handheld Doppler usage is limited by its diagnostic capabilities, thus th...
