A novel stable biomimetic adhesive coating for functionalization of orthodontic brackets against bacterial colonization and white spot lesions.
BMC Oral Health
January 2025
Oral Technology, University Hospital Bonn, 53111, Bonn, Germany.
Background: This study aimed to evaluate the efficacy of polydopamine (PDA) functionalization on orthodontic brackets in inhibiting biofilm formation and promoting surface bioactivity to buffer the acidity of caries-causing bacteria around orthodontic brackets and prevent demineralization. The stability of the coating in artificial saliva (AS) and distilled water was evaluated, along with its effect on pH changes in simulated body fluid (SBF) and distilled water.
Methods: Maxillary incisor orthodontic brackets underwent PDA functionalization using a dopamine hydrochloride solution following a specific protocol.
Clinical outcomes of closed versus open simple ankle fractures patterns requiring soft tissue reconstruction: A prospective comparative observational study.

Dept of Orthopaedics, Kings College Hospital MTC, King's College Hospital NHS Foundation Trust, London, United Kingdom.
Background: Contemporary guidelines advocate for initial debridement and single-stage definitive fixation with immediate soft tissue reconstruction for open fractures. This study aims to evaluate the effectiveness of single-stage stabilization and immediate definitive soft tissue coverage in open ankle fractures compared to closed fractures.
Methods: We compared all isolated open ankle fractures (OF) treated between January 2017 and June 2019 to a control group of operatively managed closed ankle fractures (CF).
Energy-level rich nanorings hybridizing Ag, Au and AgCl as high-performance SERS substrate for numerous molecules.

The current surface-enhanced Raman scattering (SERS) substrates typically feature a single energy level, posing challenges in coordinating electromagnetic enhancement (EM) and chemical enhancement (CM), thereby limiting the sensitive detection of numerous crucial target molecules. In this study, novel aggregated nanorings (a-NRs) hybridizing Ag, Au and AgCl are constructed as SERS substrates. On one hand, the obtained a-NRs exhibit robust localized surface plasmon resonance absorption, whose wavelength can be tuned to match three commonly used laser wavelengths (532, 633 and 785 nm) to gain strong EM effect.

School of Environmental and Municipal Engineering, Xi'an University of Architecture and Technology, Xi'an, 710055, PR China; Key Laboratory of Environmental Engineering, Shaanxi Province, Xi'an University of Architecture and Technology, Xi'an, 710055, PR China.
A self-driven electrochemical system (SDES) was utilized to treat anaerobic digestate wastewater, aiming to achieve wastewater resource utilization and energy generation. The efficiencies of pollutant removal, resource recovery, and energy production were enhanced by adjusting device parameters (anode area, external resistance, and electrode spacing). The high pollutant removal rates and struvite purity were achieved with the magnesium anode area of 15 cm, external resistance of 10 Ω, and electrode spacing of 10 cm.

Background: Some studies have revealed various sleep patterns in adolescents and adults using multidimensional objective sleep parameters. However, it remains unknown whether these patterns are consistent from adolescence to young adulthood and how they relate to long-term obesity.
Methods: Seven-day accelerometry was conducted in German Infant Study on the influence of Nutrition Intervention PLUS environmental and genetic influences on allergy development (GINIplus) and Influence of Lifestyle factors on the development of the Immune System and Allergies in East and West Germany (LISA) birth cohorts during the 15-year and 20-year follow-ups, respectively.
