cor triatriatum is an acyanotic congenital heart disease. we present a rare case of cor triatriatum sinistrum in a 6-month-old female infant who was presented with cyanosis and failure to thrive. the 2d transthoracic echocardiography and the doppler color flow imaging showed a proximal venous chamber communicating to the distal left atrium  through restrictive opening to the low-pressure, dista...

background: the purpose of this study is to demonstrate the advantages of gradient echo (gre) sequences in the detection and characterization of cerebral venous sinus thrombosis compared to conventional magnetic resonance sequences. methods: a total of 17 patients with cerebral venous thrombosis (cvt) were evaluated using different magnetic resonance imaging (mri) sequences. the mri sequences i...

Some typical problems solved by the combination and the complementary use of different investigation techniques such as boroscopy, radar and sonic tests, flat-jack and sonic tests, sonic and radar tomography and others will be presented. Résumé On présente quelques problèmes typiques concernant bâtiments historiques, résolus par l’usage de techniques d'enquête complémentaires, telles que la bor...

In this poster, we describe the design and research phase of a project that aims to create conditions for heightened sonic perception through a mobile phone based software application. The initial design concept is that of an aural architecture for sonic socio-cultural exchange where sonic realities of the everyday are improvised live in a non-linear mode. The design approach adopted is collabo...

background:  nowadays mri examinations have been widely used in clinical applications for many diagnoses. the use of contrast agent in mri improves lesion detection and characterization and causes more accurate diagnosis.  objectives: the aim of this study was comparing to optimal dose of magnevist contrast agent in modified t1w se (spin echo), t1w fse (fast spin echo) and t1w gre (gradient ech...

Sonic hedgehog promotes proliferation of developing cerebellar granule cells. As sonic hedgehog is expressed in the cerebellum throughout life it is not clear why proliferation occurs only in the early postnatal period and only in the external granule cell layer. We asked whether heparan sulfate proteoglycans might regulate sonic hedgehog-induced proliferation and thereby contribute to the spec...

Microencapsulation is a process in which solid, liquid or gas components are covered with a septum.The present study has focused on the effect of stirring to produce ferric saccharide capsules withalginate coating applying the coacervation method so that we can obtain the best capsules forfortification of hydrated and dehydrated food products. At first, three methods, including stirrer,ultra-so...

This paper develops the idea of ‘instrumentality’ to explore how use diverse tools or instruments involved in new music have potential (re)frame our engagement with world. It will be argued that choice instrumental and they are used performance can not only enrich creative processes outcomes for artist but also alter audience’s relationship world by encouraging a conceptual one more its aspects...

Background. This in vitro study aimed to compare the antibacterial effect of different concentrations of sodium hypochlorite on elimination of Enterococcus faecalis from root canal systems of primary teeth with or without a passive sonic irrigation system (EndoActivator). Methods. The root canals of 120 extracted single-rooted primary incisors were prepared using the crown-down technique. The t...

BACKGROUND Intestinal epithelial cells express the Sonic and Indian hedgehog ligands. Despite the strong interest in gut hedgehog signaling in GI diseases, no studies have specifically addressed the singular role of intestinal epithelial cell Sonic hedgehog signaling. The aim of this study was to investigate the specific role of Sonic hedgehog in adult ileal epithelial homeostasis. METHODOLOG...
