background and aims. plasma rich in growth factors (prgf) is a concentrated suspension of growth factors, which is used to promote periodontal tissue regeneration. the aim of this randomized, controlled, clinical trial was to evaluate of the treatment of grade ii mandibular molar furcation involvement using autogenous bone graft with and without prgf. materials and methods. in this double-blind...

conclusions surgical repair of the congenital mv disease yields acceptable early and intermediate-term satisfactory valve function and good survival at intermediate-term follow-up. strong predictors for poor surgical outcome and death were age smaller than 1 year, weight smaller or equal than 6 kg, and associated cardiac anomalies such as pulmonary stenosis. objectives the aim of this study was...

background pulmonary arterial hypertension (pah) is a serious complication of unrepaired congenital left-to-right shunts. the final consequence is right ventricular (rv) systolic dysfunction and reversal of shunt. objectives the aim of this study was to evaluate the clinical course and paraclinical findings in a group of patients with pah associated with congenital heart disease (pah-chd). we a...

in this paper, a new method is presented for the detection of defects in random textures. in the training stage, the feature vectors of the normal textures’ images are extracted by using the optimal response of gabor wavelet filters, and their probability density is estimated by means of the gaussian mixture model (gmm). in the testing stage, similar to the previous stage,at  first, the feature...

a secundum atrial septal defect is the most common congenital heart defect. transcatheter treatment of secundum atrial septal defects is a popular and less invasive alternative to surgery. procedural complications may occur in a wide spectrum, particularly device embolus as the most emergent one, but luckily they do not commonly occur in the clinical setting. mortality from adverse events relat...

background: butterworth, gaussian, hamming, hanning, and parzen are commonly used spect filters during filtered back-projection (fbp) reconstruction, which greatly affect the quality and size accuracy of image. materials and methods: this study involved a cardiac phantom in which 1.10 cm thick cold defect was inserted into its myocardium wall and filled with 4.0 μci/ml (0.148 mbq/ml) 99mtc conc...
