In the process of orthodontic clinical teaching, it is very important to teach medical students how they are expected to communicate effectively with patients and their families, as this has a direct impact on patient compliance throughout the process of diagnosis and treatment and on patient satisfaction after treatment. Doctor-patient communication is therefore an essential skill for medical students to gain before taking up clinical work. In view of the problems that are often encountered in each stage of orthodontic treatment, the present paper discusses the specific content of doctor-patient communication education in clinical teaching.

This study introduces a 2-layer stacked nylon mesh treated with surface diffuse atmospheric plasma (SDAP) for rapid and efficient emulsion separation. Commercial nylon mesh exhibited durable super-wetting properties after just 30 s of SDAP treatment, which was sufficient for effective emulsion separation.

By setting different loading methods and conducting Finite Element Analysis (FEA), the range of Orthodontic Torque/Support Force (OT/SF) values can be obtained. From the obtained values, it can be seen that changes in material properties have a significant impact on the mechanical properties of Kitchon-RCAA.

Human eyelashes, the primary protector of eyes, use a yet-to-be-fully-understood mechanism to efficiently transfer incoming liquid for vision safeguarding. Here, we elucidate that human eyelashes featuring a hydrophobic curved flexible fiber array with surface micro-ratchet and macro-curvature approximating the is adept at directionally and rapidly expelling incoming liquid to maintain clear vision.

However, general and effective strategies for synthesizing libraries of HEA nanocrystals with controlled surface atomic structures remain scarce. In this study, a transferable strategy for developing a library of facet-controlled seed@HEA nanocrystals through seed-mediated growth is presented.

In the indoor environment, occupants are exposed to air pollutants originating from continuous indoor sources and exchange with the outdoor air, with the highest concentration episodes dominated by activities performed indoors such as cooking and cleaning. Here we use the INdoor CHEMical model in Python (INCHEM-Py) constrained by measurements from the House Observations of Microbial and Environmental Chemistry (HOMEChem) campaign, to investigate the impact of a bleach cleaning event and cooking on indoor air chemistry. Measurements of the concentrations of longer-lived organic and inorganic compounds, as well as measured photolysis rates, have been used as input for the model, and the modelled hydroxyl (OH) radicals, hydroperoxyl radicals, and nitrous acid (HONO) concentrations compared to the measured values.

Antibiotic resistance often carries fitness costs, which typically manifest as a reduced bacterial growth rate. Here, we investigated the mechanism of fitness cost in NDM-1-producing bacteria.

We analyzed RNA sequencing (RNA-seq) data from The Cancer Genome Atlas (TCGA) and Genotype-Tissue Expression (GTEx), and sequencing data of 29 CM cell line from Cancer Cell Line Encyclopedia (CCLE) databases. Combined with DepMap database, 406 CM essential cancer genes were finally obtained.

Accelerating the alkaline hydrogen evolution reaction (HER), which involves the slow cleavage of HO-H bonds and the adsorption/desorption of hydrogen (H*) and hydroxyl (OH*) intermediates, requires developing catalysts with optimal binding strengths for these intermediates. Here, the unconventional hexagonal close-packed (HCP) high-entropy alloy (HEA) atomic layers are prepared composed of five platinum-group metals to enhance the alkaline HER synergistically. The breakthrough is made by layer-by-layer heteroepitaxial deposition of subnanometer RuRhPdPtIr HEA layers on the HCP Ru seeds, despite the thermodynamic stability of Rh, Pd, Pt, and Ir in a face-centered cubic (FCC) structure except for Ru.

Although microsurgical vasoepididymostomy (MVE) is an effective treatment for epididymal obstructive azoospermia, some patients may experience delayed patency or suboptimal semen parameters after patency. However, research into patency time, semen quality postpatency, and associated influencing factors remains limited. This study aimed to address these issues by evaluating 181 patients who underwent at least one-sided MVE employing asingle-armed longitudinal intussusception vasoepididymostomy technique, with a follow-up period of over 12 months for 150 patients.

However, traditional detection of HAase is based on changes in the flow rate caused by viscosity or requires complex modifications and processing, which limits the detection accuracy and sensitivity. Herein, hyaluronic acid (HA)-modified mesoporous-based heterochannels (mesoporous carbon-doped γ-FeO nanoparticles/anodized aluminum oxide, MC-γ-FeO/AAO) featuring ordered 3D transport frameworks and a photothermal property were developed for high performance HAase detection.

Tubular cell damage is a main characterization which results from dysregulated fatty acid oxidation (FAO) and lipid accumulation. Cannabinoid Receptor 2 (CB2) contributes to renal fibrosis, however, its role in FAO dysregulation in tubular cells is not clarified.

Ten distinct quinary compositions of IGM-PGM-HEA with precisely controlled square atomic arrangements are used to explore their impact on hydrogen evolution reaction (HER) and hydrogen oxidation reaction (HOR). The PtRuFeCoNi atomic layers perform enhanced catalytic activity and durability toward HER and HOR when benchmarked against the other IGM-PGM-HEA and commercial Pt/C catalysts.
