alzheimer’s disease (ad) is a uniquely human disorder. although the pathogenesis of ad is not fully understood, growing evidence indicates that the deposition of beta-amyloid (aβ) and the local reactions of various cell types to this protein play major roles in the development of the disease. in the present study transgenic mice expressing mutant amyloid precursor protein (app) has been used. t...

background: given the dearth of data in the existing literature on the size and morphologic variability of secundum-type atrial-septal defect (asd-ii) in adult patients, we aimed to address this issue in a series of consecutive adult patients evaluated by transesophageal echocardiography (tee). methods: a total of 50 patients (68.0% female) with isolated asd-ii underwent tee for the evaluation ...

background: transcatheter occlusion of the patent ductus arteriosus (pda) is a minimally invasive treatment. the appropriate device size is chosen based on the angiographic measurement of the pda . the current study aimed to assess the relationship between the transthoracic echocardiographic (tte) measurements of the pda prior to the occlusion procedure and the actual size of the deployed devic...

patients and methods previously recorded data of 231 patients who underwent surgical closure of vsd between january 2009 and january 2012 at the rajaie cardiovascular medical and research center were retrospectively reviewed. vsd surgical repair was performed using continues suturing technique in group a patients (n = 163, 70.6%) and interrupted suturing technique in group b patients (n = 68, 2...

OBJECTIVES This study sought to describe the acute morphologic differences that result from septal myectomy and alcohol septal ablation using cardiac magnetic resonance (CMR) imaging. BACKGROUND Surgical septal myectomy and alcohol septal ablation relieve left ventricular outflow tract obstruction in severely symptomatic patients with hypertrophic cardiomyopathy (HCM). METHODS Cine and cont...

There are some rare but probable devastating complications following any rhinoplasty. Charlin’s syndrome is a typical one. It is completely related to the external nasal nerve. In this report, we are presenting a 21-year-old female with signs and symptoms of Charlin’s syndrome, persisting for 4 years after a routine septorhinoplasty operation. Surgery was uneventful and the patient ...

total anomalous pulmonary venous connection (tapvc) is an anomaly in which the pulmonary veins are directly connected to one of the systemic veins or drain into the right atrium. management of pulmonary hypertension after the total correction of this congenital cardiac anomaly is very important. unligation of the vertical vein in the supracardiac type of this anomaly can be a draining pathway f...

introduction: nasal teeth eruption is a rare phenomenon. the variability of symptoms and generic history makes the diagnosis difficult. this difficulty is more challenging when the tooth is placed in the depth of septum.   case report: our case is an example of this problem. herein, we present a case of intraseptal tooth with nasal obstruction and septal deviation and recurrent sinusitis. we pr...
