PURPOSE The goal of this in vitro study was to identify the topographical features of the enamel surface deproteinized and etched with phosphoric acid (H3PO4) compared to phosphoric acid alone. MATERIALS AND METHOD Ten extracted lower first and second permanent molars were polished with pumice and water, and then divided into 4 equal buccal sections(More)
BACKGROUND AND PURPOSE Despite prominent neurological symptoms reported in Takayasu arteritis (TA), a complete evaluation of the cerebral circulation has not been consistently performed. The purpose of this study is to describe MR angiography (MRA), color Doppler flow imaging, and transcranial Doppler (TCD) findings in the extracranial and intracranial(More)
BACKGROUND Ionizing radiation has been shown to reduce neointimal formation after balloon angioplasty in experimental models of restenosis. This study was designed to evaluate the feasibility, safety, and effectiveness of intracoronary radiation therapy (ICRT) after percutaneous transluminal coronary angioplasty (PTCA) for preventing restenosis in human(More)
During the last 22 months, a total number of 85 tracheostomies have been performed in our ICU, 40 of which have been surgical, and 45 percutaneous to patients under mechanical ventilation. This period has coincided with the learning process of the technique of percutaneous tracheostomy by our staff. The choice of the type of tracheostomy was not taken at(More)
Citizens demand more and more data for making decisions in their daily life. Therefore, mechanisms that allow citizens to understand and analyze linked open data (LOD) in a user-friendly manner are highly required. To this aim, the concept of Open Business Intelligence (OpenBI) is introduced in this position paper. OpenBI facilitates non-expert users to (i)(More)
OBJECTIVE Our goal was to evaluate the impact of fetal compromise on the outcome of borderline viable babies. STUDY DESIGN All 142 babies born in our hospital from 1990 to 1995 with a gestational age of 23 to 25 weeks were included. Fetal compromise was considered present if one of the following was documented: a major anomaly, congenital sepsis, chronic(More)
A successful data mining process depends on the data quality of the sources in order to obtain reliable knowledge. Therefore, prepro-cessing data is required for dealing with data quality criteria. However, preprocessing data has been traditionally seen as a time-consuming and non-trivial task since data quality criteria have to be considered without any(More)
OBJECTIVE To assess the intra- and interobserver reproducibility of musculoskeletal ultrasonography (US) in detecting inflammatory shoulder changes in patients with rheumatoid arthritis, and to determine the agreement between US and the Shoulder Pain and Disability Index (SPADI) and the Disabilities of the Arm, Shoulder, and Hand (DASH) questionnaire, using(More)
PURPOSE The goal of this in vitro study was to identify the topographical features of deproteinized (NaOCl) and etched with phosphoric acid (H3PO4) enamel surface, compared to phosphoric acid surface alone with a Resin Replica model. MATERIALS Ten extracted lower first and second permanent molars were polished with pumice and water, and then divided into(More)
