In a patient with obstructive left atrial myxoma, we analyzed by pulsed Doppler echocardiography the flow pattern through the mitral valve and in the pulmonary veins. Two mitral flow patterns were observed: the first was present near the medial commissure and along the anterior leaflet and was characterized by the absence of mid-to-late diastolic filling flow; the second was found near the late...

Postcontrast Time-of-Flight MR Angiography Demonstrating Collateral Flow in Acute Stroke To the Editor: In their interesting study, Pedraza et al1 showed that the postperfusion contrast-enhanced time-of-flight (TOF) MR angiography (Post-CE-MRA) can demonstrate arterial segment with low flow and avoid overestimation of vascular obstruction. We agree that Post-CE-MRA supplies additional informati...

conclusions there was no significant statistical difference between mta and cem cement in sealing ability (p > 0.05). results the mean apical penetration of dye in the mta group was 0.94 mm while in the cem cement group this was 1.17 mm. eighty percent of the mta group and 75% of the cem cement group didn’t have any dye leakage. the p level was greater than 0.05 (0.592). materials and methods e...

This paper examines options for orbit configurations a space interferometer. In contrast to previously presented concepts very long baseline interferometry, we propose combination of regular and retrograde near-Earth circular orbits in order achieve faster filling (u,v) coverage. With the rapid relative motion telescopes, it will be possible quickly obtain high quality images supermassive black...

Background/Aim: This in-vitro study evaluated the apical-sealing ability of MTA, MTA+10% CaCl2, Biodentine™ and RMGIC when used as retrograde material. Material Methods: A total 80 single-rooted bovine incisors were decoronated, instrumented, divided into 4 groups according to material, follows: Group 1: MTA (ProRoot Dentsply); 2: Dentsply) + 10% CaCl2; 3: Biodentine (Biodentine®, Septodont); 4...
