Background: Random-pattern flap transfer is commonly used to treat soft-tissue defects. However, flap necrosis remains a serious problem. Naringin accelerates angiogenesis by activating the expression of vascular endothelial growth factor (VEGF). In the present study, we investigated whether naringin improves the survival of random skin flaps. Results: Compared with controls, the naringin-treated groups exhibited significantly larger mean areas of flap survival, significantly increased SOD activity and VEGF expression, and significantly reduced MDA level...

Deformation imaging (strain imaging) is an echocardiographic method for evaluating myocardial function that is also suitable for clinical use. There are two deformation imaging techniques: Tissue Doppler and 2D strain (speckle tracking). Deformation imaging allows the measurement of regional myocardial deformation in three dimensions. Longitudinal deformation (strain) measures longitudinal myocardial fiber contraction, and reflects subendocardial myocardial function, which is usually the first to deteriorate in patients with heart disease...

Introduction: Transcranial Doppler ultrasonography (TCD) is a clinical tool for stratifying ischemic stroke risk by identifying abnormal elevations in blood flow velocity (BFV) in the middle cerebral artery (MCA). However, TCD is not effective at screening for subtle neurologic injury such as silent cerebral infarcts. To better understand this disparity, we compared TCD measures of BFV with tissue-level cerebral blood flow (CBF) using arterial spin-labeling MRI in children with and without sickle cell disease, and correlated these measurements against clinical hematologic measures of disease severity...

AL-amyloidosis is a rare, but complex disease, with a severe prognosis, cardiac involvement being found in half of the patients. The rapid increase of the LV wall thickness predicts an unfavorable evolution. We report the case of a 63-year-old man diagnosed with AL-amyloidosis, with cardiac involvement, associated with multiple site thrombosis.  Specific echocardiographic methods like tissue Doppler imaging and speckle tracking provided crucial diagnostic and prognostic information.

BACKGROUND: Cardiac resynchronization therapy (CRT) is an effective treatment for patients with advanced heart failure (HF). Nearly 30% of candidates are inadequate responders. The benefit of patients with right sided heart failure from CRT is still a matter of debate. We examined the effect of CRT on right ventricular (RV) dimensions and overall systolic function and whether RV function prior to CRT could have an impact on CRT response. METHODS: 94 patients with a mean age of 53...

BACKGROUND: Left bundle branch block (LBBB) and left axis deviation (LAD) patients may have poor response to resynchronization therapy (CRT). We sought to assess if LBBB and LAD patients show a specific pattern of mechanical asynchrony. METHODS: CRT candidates with non-ischemic cardiomyopathy and LBBB were categorized as having normal QRS axis (within -30° and +90°) or LAD (within -30° and -90°). Patients underwent tissue Doppler imaging (TDI) to measure time interval between onset of QRS complex and peak systolic velocity in ejection period (Q-peak) at basal segments of septal, inferior, lateral and anterior walls, as expression of local timing of mechanical activation...

STUDY QUESTION: Does the use of a vascular contrast agent facilitate earlier detection of maternal flow to the placental intervillous space (IVS) in the first trimester of pregnancy? SUMMARY ANSWER: Microvascular filling of the IVS was demonstrated by contrast-enhanced ultrasound from 6 weeks of gestation onwards, earlier than previously believed. WHAT IS KNOWN ALREADY: During placental establishment and remodeling of maternal spiral arteries, endovascular trophoblast cells invade and accumulate in the lumen of these vessels to form 'trophoblast plugs'...

Background: Myocardial dysfunction may contribute to circulatory failure in sepsis. There is growing evidence of an association between left ventricular diastolic dysfunction (LVDD) and mortality in septic patients. Utilizing echocardiography, we know that tissue Doppler imaging (TDI) variables e' and E/e' are reliable predictors of LVDD and are useful measurements to estimate left ventricular (LV) filling pressures. Methods: We conducted a systematic review and meta-analysis to investigate the association of e' and E/e' with mortality of patients with severe sepsis or septic shock...

Background: Though diastolic interrogation of the mitral annulus (MA) using tissue Doppler imaging (TDI) has been quite useful in assessing left ventricular (LV) diastolic function, the relative contribution of the previous cycle MA systolic displacement or velocity components to subsequent LV diastole has not been previously investigated. We therefore sought to determine the association between MA systolic dynamics and LV diastolic function parameters. Methods: For this retrospective study, only complete echocardiograms having good endocardial border resolution of both left atrial (LA) and LV chambers with M-mode (MAPSE) and tissue Doppler of the lateral MA (MA TDI S') as well as complete Doppler data to perform assessment of LV diastole were included in our analysis...
