This investigation presents additional evidence for the hemodynamic influence of intracardiac anomalies on the development of the aortic arch, based on measurements of different parts of the great vessels. Criteria are given to define the normal aortic arch and the different anomalies of the aortic arch, such as interruption, atresia, tubular hypoplasia, hypoplasia, abnormal long segment and ju...

AIM Simulation has been proposed to improve learning curves in carotid artery stenting (CAS), but previous studies have only evaluated CAS simulation in a single type of arch usually either type I or type II. The aim of our study is to define the use of virtual reality for CAS training in type I and type III aortic arches for novice operators. MATERIALS AND METHODS Fifty experienced intervent...

BACKGROUND The purpose of this study is to evaluate the relationship between dental arch form and the vertical facial pattern determined by the angle between the mandibular plane and the anterior cranial base (Sella-nasion/mandibular plane angle (SN-MP)) in skeletal class II untreated patients. METHODS A sample of 73 Caucasians patients with untreated skeletal class II in permanent dentition ...

: To compare the aligning efficiency, pain experienced by patient during alignment and post third order values of anterior teeth in I arch (study) group conventional NiTi (control) wire group. A prospective clinical study. total 40 dental arches (maxilla/mandible) were divided into 2 study groups with 20 each based on selection criteria. Group I. Twenty (maxillary/mandibular) having 0.018” prea...

OBJECTIVE The purposes of this study were 1) to classify lingual dental arch form types based on the lingual bracket points and 2) to provide a new lingual arch form template based on this classification for clinical application through the analysis of three-dimensional virtual models of normal occlusion sample. METHODS Maxillary and mandibular casts of 115 young adults with normal occlusion ...

A longstanding goal in neuroscience has been to develop techniques for imaging the voltage dynamics of genetically defined subsets of neurons. Optical sensors of transmembrane voltage would enhance studies of neural activity in contexts ranging from individual neurons cultured in vitro to neuronal populations in awake-behaving animals. Recent progress has identified Archaerhodopsin (Arch) based...

Methods The conventional 2D method is based on a single view of the aorta which is combined with phase contrast acquisitions to define the starting and stopping points of the arch, where velocities are measured. For the 3D measurement, SSFP axial and sagittal slices including the aortic arch are considered. Two operators measured the 3D length of the arch by delimiting markers on the different ...
