Mechanical and viscoelastic properties of a temperature-responsive photocurable resin for 3D printed orthodontic clear aligners.

This study investigates the mechanical and viscoelastic properties of TC-85, a biocompatible material specifically designed for orthodontic applications, with a focus on how temperature variations influence its mechanical and viscoelastic properties and their relevance to clinical outcomes. Using a Digital Light Processing (DLP) 3D printer, the photosensitive resin TC-85 is printed, and extensive thermo-mechanical testing is conducted, which includes evaluations of tensile modulus, stress relaxation, and creep behavior. Dynamic Mechanical Analysis (DMA) is conducted at temperatures varying from 30 to 45 °C to assess the material's adaptive response to thermal fluctuations.

Clinical Practice Guidelines for Diagnosis and Non-Surgical Treatment of Primary Frozen Shoulder.

Nano-Interconnected 1D/2D Boron Nitride Hybrid Networks: Unlocking Superior Thermal Conductivity in Electrically Insulating Thermal Interface Nanocomposites Based on Hybrid Thermal Percolation Model.

Due to its high thermal and low electrical conductivities, boron nitride (BN) has emerged as an optimal filler for thermal interface materials (TIMs) that prevent thermal condensation of nanostructures without causing shutdown due to electron tunneling. The polymer composite based on the BN hybrid strategy can be considered an optimal option as an electrically insulating and heat-dissipating TIM. However, there is a paucity of systematic experiments and theoretical approaches investigating the optimal content and ratio of BN hybrid fillers, which are key factors in synergistically improving thermal conductivity (TC).

Comparison of treatment effects with or without miniscrews for maxillary protraction in growing patients with Class III malocclusion.

Introduction: This study aimed to compare the skeletal and dental effects of maxillary protraction using a miniscrew-assisted rapid palatal expander (MARPE) and rapid palatal expander in growing patients with skeletal Class III malocclusion undergoing maxillary protraction.

Methods: This study included 18 patients in the facemask (FM) treatment with MARPE (group 1) and 20 patients in the FM treatment with rapid palatal expander (group 2). In addition, a control group (group 3) consisting of 21 patients undergoing no treatment affecting maxillary growth was established.

A keyword-based approach to analyzing scientific research trends: ReRAM present and future.

Research trend analysis is a primary step in defining research structures and predicting research directions from scientific papers. Recently, due to millions of annual scientific publications, researchers demand analytical methods to interpret the research field topologically and temporally. In this study, we propose a keyword-based research trend analysis method that automatically and systematically analyzes the research field by extracting keywords and constructing a keyword network.

Outcomes of footprint medialization and bone marrow stimulation in chronic retracted rotator cuff tears.

Background: This study compared the clinical and radiological outcomes of chronic retracted rotator cuff tears where complete footprint coverage cannot be achieved, using two treatments: footprint medialization with bone marrow stimulation and conventional incomplete repair.

Methods: This retrospective study included 87 patients who underwent arthroscopic rotator cuff repair with incomplete footprint coverage. The included patients were divided into group 1 (54 patients with footprint medialization and bone marrow stimulation) and group 2 (33 patients with conventional repair).

Impacts of medial collateral ligament (MCL) stiffness adjustment on knee joint mechanics in mechanically aligned posterior-substituting (PS) total knee arthroplasty (TKA).

To investigate the biomechanical effects of medial collateral ligament (MCL) stiffness adjustments on knee kinematics-medial femoral rollback, femoral rotation, and joint contact forces-in mechanically aligned posterior-substituting (PS) total knee arthroplasty (TKA). A musculoskeletal model simulating squatting was developed using the AnyBody modeling system. A PS-TKA prosthesis was implanted, and MCL stiffness was modified in 20% increments.

GNAO1: A Novel Tumor Suppressor Gene in Colorectal Cancer Pathogenesis.

Background/aim: This study examined the role of GNAO1 as a potential tumor suppressor gene in colorectal cancer (CRC).

Materials And Methods: RNA-seq data analysis revealed a significant GNAO1 down-regulation in colon cancer tissues compared to normal colon tissues.

Results: GNAO1 over-expression in CRC cell lines inhibited cell proliferation, migration, and tumor formation both in vitro and in vivo.

Correlations of temporomandibular joint morphology and position using cone-beam computed tomography and dynamic functional analysis in orthodontic patients: A cross-sectional study.

Objective: To correlate temporomandibular joint (TMJ) morphology and position with cone-beam computed tomography (CBCT) images, Joint Vibration Analysis (JVA), and Jaw Tracker (JT) to develop a radiation-free, dynamic method for screening and monitoring the TMJ in orthodontic patients.

Methods: A total of 236 orthodontic patients without symptoms of TMJ disorders who had undergone CBCT were selected for the JVA and JT tests in this cross-sectional study. TMJ position and morphology were measured using a three-dimensional analysis software.

HN1-mediated activation of lipogenesis through Akt-SREBP signaling promotes hepatocellular carcinoma cell proliferation and metastasis.

Hepatocellular carcinoma (HCC) is the second leading cause of cancer-related deaths worldwide, with more than 800,000 deaths each year, and its 5-year survival rate is less than 12%. The role of the HN1 gene in HCC has remained elusive, despite its upregulation in various cancer types. In our investigation, we identified HN1's heightened expression in HCC tissues, which, upon overexpression, fosters cell proliferation, migration, and invasion, unveiling its role as an oncogene in HCC.

Biomechanical Characteristics of Glenosphere Orientation Based on Tilting Angle and Overhang Changes in Reverse Shoulder Arthroplasty.

Background: Glenoid position and inclination are important factors in protecting against scapular notching, which is the most common complication that directly affects the longevity of reverse shoulder arthroplasty (RSA). This study aimed to investigate the biomechanical characteristics of glenosphere orientation, comparing neutral tilt, inferior overhang with an eccentric glenosphere at the same placement of baseplate, and inferior tilt after 10° inferior reaming in the lower part of the glenoid in RSA.

Methods: Nine cadaveric shoulders were tested with 5 combinations of customized glenoid components: a centric glenosphere was combined with a standard baseplate (group A); an eccentric glenosphere to provide 4-mm inferior overhang than the centric glenosphere was combined with a standard baseplate (group B); a centric glenosphere was combined with a wedge-shaped baseplate tilted inferiorly by 10° with the same center of rotation (group C); an eccentric glenosphere was attached to a wedge-shaped baseplate (group D); and 10° inferior reaming was performed on the lower part of the glenoid to apply 10° inferior tilt, with a centric glenosphere secured to the standard baseplate for simulation of clinical tilt (group E).
