BACKGROUND Various dyssynchrony indexes derived from tissue velocity and strain imaging have been proposed to predict the effectiveness of cardiac resynchronization therapy (CRT). We sought to compare the effect of CRT on dyssynchrony indexes derived by tissue velocity and strain and to determine which baseline intraventricular dyssynchrony parameters correlate with improvement in left ventricu...

In this paper, we suggest a new technique to create index helping to query almost identical similarities with keywords in case there is no correct match found. It is based on a SD-Tree and a n-ary Tree helping to query related information when there is no correct match. Index structure arranges signatures according to hierarchical clustering for improving assessment of query. This method is bas...

We have compared the auditory evoked potential index (AEPIndex) and bispectral index (BIS) for monitoring depth of anaesthesia in spontaneously breathing surgical patients. Twenty patients (aged 17-49 yr) undergoing day surgery were anaesthetized with computer-controlled infusions of propofol. The mean (SD and range) of each measurement was determined during consciousness and unconsciousness an...

BACKGROUND The corticospinal excitability indexed by motor evoked potentials (MEPs) following transcranial magnetic stimulation (TMS) of the sensorimotor cortex is characterized by large variability. The instantaneous phase of cortical oscillations at the time of the stimulation has been suggested as a possible source of this variability. To explore this hypothesis, a specific phase needs to be...

Working Papers are a series of manuscripts in their draft form. They are not intended for circulation or distribution except as indicated by the author. For that reason Working Papers may not be reproduced or distributed without the written consent of the author. Abstract This paper examines investor preferences for oil spot and futures based on mean-variance (MV) and stochastic dominance (SD)....

To compare the birth weight (BW) of largest prior vaginal delivery versus the index pregnancy with shoulder dystocia (SD). From three centers, births with SD were identified and compared to the largest birth weight of prior delivery at term. Among 304 patients, the mean difference in the BW of those with SD in the index pregnancy and largest prior vaginal delivery was 394 ± 510g (p<.0001). The ...

BACKGROUND Myocardial performance index (MPI) or Tei index is a Doppler-derived index of combined systolic and diastolic myocardial function, calculated as the sum of isovolumetric relaxation time (IRT) and isovolumetric contraction time (ICT) divided by the ejection time (ET). OBJECTIVE To evaluate the right and left ventricular systolic and diastolic function using MPI in children before an...

background and purpose: dental caries or tooth decay is one of the most important health problems in human life. in addition, tooth decay is an infectious disease that affects all populations worldwide. the purpose of this study was to determine the decayed, missing and filled teeth (dmft) index among a representative sample of 8-12 years old school children in zahedan city, iran. materials and...

BACKGROUND Seborrheic dermatitis (SD) is a common inflammatory skin condition. The etiology is unclear, although overgrowth of Malassezia on the skin has been suggested to cause SD. This study investigated whether colonization with Staphylococcus plays a role in facial SD, which was not well addressed previously. METHODS The study was conducted from September 1, 2011 to February 20, 2012 in t...

Species diversity, richness and biomasses (aboveground biomass) and their relationships are the key variables of ecosystems. This study was conducted to determine the relationship of Species Diversity (SD) and Species Richness (SR) with Above-Ground Biomass (AGB) at a local scale at 5 different habitats (shrubland, forbland, grassland, shrub-forbland and forb-shrubland) in Zagros mountains in w...
