background: sickle-cell disease (scd) is an inherited hemoglobin childhood disorder, frequently complicated by pulmonary hypertension and cardiac involvement. cardiovascular events and complications are the leading cause of mortality and morbidity in patients with scd. tissue doppler imaging and the myocardial performance index (tei index), are simple indices for the assessment of the cardiac f...

background reversibility of advanced fibrosis after hcv-clearance is an important goal of therapy. objectives measuring liver stiffness (ls) by transient elastography (te) might be helpful in this setting. patients and methods we evaluated 104 patients with biopsy-proven chronic hepatitis c (chc) and sustained virological response (svr) after peg-interferon (ifn) plus ribavirin since at least 1...

conclusions sm wave in tdi is prominent and significantly high in mvp syndrome. also, our study showed some degree of diastolic dysfunction in mvp patients. results seventy-five patients (48 females) at a mean age of 26.5 ± 9.4 years and 50 individuals (32 females) at a mean age of 27.1 ± 8.3 years were enrolled in the study. as the important results of our study, sm wave was much more prominen...

background: left ventricular (lv) twist is due to oppositely directed apical and basal rotation and has been proposed as a sensitive marker of lv function. we sought to assess the impact of chronic pure mitral regurgitation (mr) on the torsional mechanics of the left human ventricle using tissue doppler imaging. methods: nineteen severe mr patients with a normal lv ejection fraction and 16 non-...

background pulmonary artery hypertension is the presentation of various types of cardiovascular and systematic diseases. there are different kinds of noninvasive methods to determine right ventricular function, pulmonary artery pressure, and effect of pulmonary hypertension on right ventricular function. these methods include the tissue doppler imaging (tdi) of the tricuspid annulus and the lon...

OBJECTIVE To examine the potential value of preinduction cervical length, cervical elastography and angle of progression (AOP) in prediction of successful vaginal delivery and induction-to-delivery interval. METHODS This was a prospective study in 99 women with singleton pregnancy undergoing preinduction ultrasound assessment at 35-42 weeks' gestation. Cervical length, elastographic score at ...

This article argues that the difference between poor countries and rich countries has to do with governance rather than resources, emphasizing the importance of public administration in explaining economic success and failure. Political elasticity (PE) theory is introduced for the analysis presented here, including the following terminology: (1) political elasticity, (2) political inelasticity,...

AIM To evaluate the association between cervical strain assessed with quasi-static elastography and spontaneous preterm delivery. METHODS Quasi-static elastography was used to estimate cervical strain in 545 pregnant women with singleton pregnancies from 11 weeks to 28 weeks of gestation. Cervical strain was evaluated in one sagittal plane and in the cross-sectional planes of the internal cer...
