Treatment effects of modified miniscrew-assisted rapid palatal expander and rapid palatal expander for molar distalization.

Objectives: To evaluate the treatment effects of the modified miniscrew-assisted rapid palatal expander (MARPE) and rapid palatal expander (RPE) with distalizers in patients with Class II malocclusion and maxillary crowding.

Materials And Methods: The sample comprised 28 skeletal Class I adolescents with dental Class II malocclusion and maxillary crowding of >4 mm who received nonextraction treatment. Fourteen patients were treated with a modified MARPE with distalizer (MMD), while another 14 patients were treated with a modified RPE with distalizer (MRD).

Hardiness Mediates Stress and Impact Level in ED Nurses Who Experienced a Violent Event.

Introduction: This secondary analysis examined the mediating effect of hardiness between stress and impact level in ED nurses who experienced a violent event.

Method: This correlational study was conducted from June to August 2014. We used the visual analog scale to measure stress level, the Impact of Event Scale-Revised to measure impact level after the violent event, and the Dispositional Resilience Scale to measure hardiness.

Comparing Stability of Mandibular Setback Versus 2-Jaw Surgery in Class III Patients With Minimal Presurgical Orthodontics.

Purpose: The aim of this study was to compare treatment time and skeletal stability between mandibular setback surgery (MS) and 2-jaw surgery (2J) with minimal presurgical orthodontics (MPO) in patients with skeletal Class III.

Materials And Methods: One hundred ninety-five patients who underwent orthognathic surgery were enrolled in this retrospective cohort study. Consecutive patients were selected based on standardized inclusion criteria: Class III malocclusion with mandibular prognathism, surgery type, and presurgical orthodontics with non-extraction for less than 6 months (MPO).

Comparative evaluation of the sliding plate technique for fixation of a sagittal split ramus osteotomy: finite element analysis.

Objective: This study evaluated the stress distribution of the sliding plate (SP) and conventional miniplate (CM) fixation techniques of a sagittal split ramus osteotomy (SSRO) using 3-dimensional (3-D) finite element analysis.

Study Design: Four 3-D finite element models according to the number and shape of screw holes in the plate were simulated, and the von Mises stress was analyzed: SP with 2 round and 2 oval holes (SP-2 R2 O), SP with 2 round and 1 oval holes (SP-2 R1 O), CM with 4 round holes (CM-4 R), and CM with 3 round holes (CM-3 R).

Results: The fixation technique with CM-4 R showed a better stress distribution than CM-3 R, which in turn showed better results compared to the 2 different SPs.

[Validity and Reliability of ARQ-K (Korean Version of the Assault Response Questionnaire) for Emergency Department Nurses in Korea].

Purpose: To investigate the validity and reliability of the Korean Version of the Assault Response Questionnaire (ARQ-K) measuring the intensity of reaction to victimization of emergency nurses in Korea.

Methods: An internal consistency reliability and construct validity using exploratory and confirmatory factor analysis were conducted using SPSS WIN (20.0) and AMOS (20.

Evaluation of soft tissue changes around the lips after bracket debonding using three-dimensional stereophotogrammetry.

Objective: To evaluate the changes in soft tissue around the lips after orthodontic bracket debonding using three-dimensional (3-D) stereophotogrammetry.

Materials And Methods: 3-D facial images of 20 subjects (10 men and 10 women; mean age, 26.81 ± 7.

Inhibition of NF-kappaB acetylation and its transcriptional activity by Daxx.

We propose a biochemical mechanism by which Daxx modulates NF-kappaB transcriptional activity. Both chromatin immunoprecipitation (ChIP) assay and electrophoretic mobility shift assay (EMSA) have confirmed Daxx-mediated repression of transcriptional competence of NF-kappaB in HeLa cells. Overexpression of Daxx repressed the expression of NF-kappaB-regulated genes such as I kappa B alpha and IL8.
