PURPOSE To determine the relationship between delayed patchy choroidal filling and morphologic and functional outcomes among eyes treated with ranibizumab or bevacizumab. DESIGN Cohort study. METHODS Comparison of Age-related Macular Degeneration Treatment Trials participants were assigned randomly to ranibizumab or bevacizumab on a monthly or as-needed schedule. Presence of delayed patchy ...

OBJECTIVES The purpose of this in vitro quantitative laboratorial study is to compare the ability of three filling techniques to fill simulated lateral canals. METHODS Thirty extracted, single-rooted human teeth were used. After cleaning and shaping, three lateral canals were created, one in each third. The teeth were randomly separated into three groups: continuous wave of condensation (Grou...

OBJECTIVES The aim of the present study was to determine radiographically the different reasons and problems of endodontic treatment failure. METHODS The periapical radiographs of 100 patients with one hundred teeth (130 root canals) were examined to identify the problems and failures of endodontic treatment. The various reasons of failure that is under filling, poor filling, over filling and...

Method 23 patients with STEMI undergoing primary PCI were prospectively enrolled and sequential CMR imaging was performed within 96 hours of admission and at 1 month follow up. LV volumetric quantification was performed (QMass MR, Medis, Leiden, The Netherlands) with manual planimetry of the endocardial contours in all temporal phases of the contiguous short-axis slices. Systolic parameters wer...

objectives: the incidence of stereotyped behaviors is one of the major symptoms of diagnosis of individuals with autism spectrum disorder that causes disruption in daily life. this study aimed at evaluating the effectiveness of ball exercises on the reduction of stereotypical behavior of children with autism spectrum disorder. methods: in this study, 16 children (boys) with autism spectrum diso...

Objective: To describe filling patterns and associated transcriptional aspects in phlebotomy tubes received at PNS Rahat laboratory. Material and Methods: This descriptive study was carried out from November 2006 to August 2007 at Department of Pathology, PNS Rahat, Karachi. Phlebotomy related data was collected from various blood collection tubes and associated request/authorization forms from...

BACKGROUND The purpose of this study was to compare the efficacy of nickel-titanium rotary systems with or without the retreatment instruments in the removal of gutta-percha from the apical third. METHODS The systems compared were as follows: ProTaper Universal (PT), ProTaper Universal Retreatment (PTr), Mtwo (M2) and Mtwo Retreatment (M2r). Sixty extracted mandibular incisors were treated wi...

We investigated artifacts due to late-arriving contrast medium (CM) during C-arm cone-beam computed tomography. We scanned a phantom filled with water or with 100, 50, or 5% v/v concentrations of CM and then virtually produced CM-delayed projection data by partially replacing the projection images. Artifacts as a function of concentration, percentage of filling time, and size and position of th...

Gearboxes are frequently used in the mining industry, especially for power transmission between electric drive and ball mill; besides extreme complexity of a mill gear system, fault diagnosis by vibration analysis can be easily distorted presence impulsive noises due to pulses on shell. Although several works literature related influence an noise accuracy diagnosis, no dynamic model exists yet ...
