Objective- To evaluate kidney hemodynamic response including blood flow velocity in segmental arteries shortly after administration of various dose of saffron extract (10, 40 and 90 mg/kg). Design- Technical assessment, experimental study. Animals- 20 healthy male Sprague-Dawley rats. Procedures- In this study, using a real-time pulsed doppler analysis, kidney hemodynamic response inc...
BACKGROUND This study evaluated 3 new automated methods, based on a combination of speckle tracking and tissue Doppler, for the analysis of strain rate (SR) and strain. Feasibility and values for peak systolic strain rate (SR s ) and end-systolic strain (S es ) were assessed. METHODS Thirty patients with myocardial infarction and 30 normal subjects were examined. Customized software with auto...
Introduction: Digital Subtraction Angiography (DSA) is the standard method for detection of carotid artery stenosis. This technique has high radiation dose. With the progress of imaging techniques, noninvasive or minimally invasive methods like the CT angiography, MR angiography and ultrasonography with Doppler or Duplex mode were applicable. This study aimed to evaluate and assesse the results...
OBJECTIVES To determine the frequency, associated clinical factors, and prognostic significance of left ventricular (LV) diastolic dysfunction in systemic sclerosis (SSc). METHODS We studied 153 consecutive patients with SSc and divided the study sample into those with and without LV diastolic dysfunction using established age-based normal cut-offs for lateral tissue Doppler early mitral annu...
