OBJECTIVES We sought to evaluate whether clinical, lesion-related and procedural factors may predict in-stent restenosis (ISR) after intracranial stenting. METHODS Sixty-one Chinese patients with 65 lesions treated with single bare metal balloon-mounted stent for symptomatic intracranial arterial stenosis underwent conventional angiographic follow-up after procedures between March 2004 and Ju...
investigating the feasibility of a proposed model for geometric design of deployable arch structures
deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
Background: Bare-metal stents are widely used in Chinese population with coronary artery disease. Many reports of predictors of in-stent restenosis (ISR) are available from trials mainly conducted in the Western population. However, predictors of ISR in Chinese population are rarely described. Methods: This study enrolled 609 patients who had procedural success of coronary stenting with bare-me...
phatic communion is a cultural concept which differs across cultures. according to hofstede (2001), the u.s. tends to have individualistic culture; however, asian countries tend to have collectivistic cultures. these cultures view phatic communion differently. in individualistic cultures like u.s., phatic communion reflects speakers’ socio-cultural relationships in conversations. to see whether...
BACKGROUND AND PURPOSE The accuracy of carotid ultrasound has not been well established in predicting intrastent restenosis (ISR) after carotid artery stenting (CAS). The aim of this study is to determine different degrees of ISR using ultrasound velocity criteria compared to percentage of stenosis at angiography. METHODS This is a 6-year prospective study. After CAS procedure, each patient u...
Plants develop an enhanced defensive capacity against a broad spectrum of plant pathogens after colonization of the roots by selected strains of nonpathogenic, fluorescent Pseudomonas spp. In Arabidopsis thaliana, this rhizobacteria-induced systemic resistance (ISR) functions independently of salicylic acid but requires responsiveness to the plant hormones jasmonic acid and ethylene. In contras...
the application of e-learning systems - as one of the solutions to the issue of anywhere and anytime learning – is increasingly spreading in the area of education. content management - one of the most important parts of any e-learning system- is in the concern of tutors and teachers through which they can obtain means and paths to achieve the goals of the course and learning objectives. e-learn...
learning-oriented assessment seeks to emphasise that a fundamental purpose of assessment should be to promote learning. it mirrors formative assessment and assessment for learning processes. it can be defined as actions undertaken by teachers and / or students, which provide feedback for the improvement of teaching and learning. it also contrasts with equally important measurement-focused appro...
cultural iran is a scope that is more extended than the political territories of iran as a political unit. this concept means that cultural geography(mehdi moghanlo-1383-1) of iran is greater than its political geography which, according to history, has a long history extending west-east from kandahar to the euphrates and north-south from the persian gulf to the caucasus including transoxiana a...
BACKGROUND AND AIM Many studies have reported that genetic variants correlate with higher risk for coronary artery disease (CAD) or in-stent restenosis (ISR) after bare metal stent (BMS) implantation. However, there is limited data assessing the impact of these variants on ISR in patients treated with drug-eluting stent (DES). The purpose of this study was to investigate the effects of genetic ...
