Abstract

The COVID-19 outbreak has disrupted undergraduate students' experiments since their access to the laboratory is limited. To address this problem, the bacteria and detergent residues on undergraduate students' dinner plates were investigated by the students in the dormitories. Five different types of dinner plates from 50 students were collected, which were cleaned with detergent and water in the same way and naturally dried. Then, Escherichia coli ("E. coli") test papers and sodium dodecyl sulfonate test kits were used to understand the bacteria and detergent residuals. Commonly available equipment such as a yogurt maker was used for bacterial culture; detergent analyses were performed using centrifugation tubes. Effective sterilization methods and safety protection were achieved by dormitory available methods. According to the investigated results, the students found the differences in bacteria and detergent residuals between different dinner plates and made suitable choices for the future.

The Ti surfaces coated with such a layer (Si–Sr-TNs) were characterized with different techniques.Results: The results indicate that the Si4+ and Sr2+ ions were evenly incorporated into the TNs and that the Si–Sr-TN layer provides good protection against corrosive media like simulated body fluid. The excellent cytocompatibility of the coating was confirmed in vitro by the significant growth and differentiation of MC3T3-E1 osteoblastic cells.Conclusion: Being easily and economically fabricated, the Si–Sr-TN surfaces may find their niche in clinical applications, thanks to their excellent biological activity and corrosion resistance.

46. “Dual-functional” strontium titanate nanotubes designed based on fusion peptides simultaneously enhancing anti-infection and osseointegration

Abstract

Currently, there is an increasing clinical demand for implants that effectively resist bacterial infections while promoting osseointegration. In this study, the fusion peptide technology was used to linearly fuse the antimicrobial peptide (AMP, HHC36) and the bone-promoting peptide (RGD), so that the titanium (Ti)-based implant modified by the polypeptide had the dual function of “antibacterial-promoting bone”. Firstly, self-organized vertically-oriented strontium-doped titanium dioxide nanotubes (STN) were manufactured by anodizing and hydrothermal synthesis methods. Secondly, the fusion peptide (HHC36-RGD) was loaded into the tubular structure by a simple vacuum-assisted physical adsorption method. Finally, STN loaded with HHC36-RGD (H-R-STN) was obtained. The characterization results demonstrated that the surface of the H-R-STN had a roughness and hydrophilicity that promoted cell adhesion. Additionally, electrochemical tests showed that H-R-STN coating can reduce the corrosion rate of pure Ti. The fusion peptide and Sr2+in H-R-STN were released in the initial fast and subsequent slow kinetic model. Expected, H-R-STN can kill more than 99% of clinically common pathogenic bacteria (Staphylococcus aureusand Escherichia coli), and significantly inhibit the formation of bacterial biofilms. Simultaneously, under the synergistic effect of RGD in the fusion peptide and strontium in STN, H-R-STN markedly promoted the adhesion and proliferation of mouse osteoblasts, and significantly promoted osteogenic markers (alkaline phosphatase, runt-related transcription, collagen, mineralization) expression. In summary, the bifunctional titanium-based implant constructed by H-R-STN in this article can effectively prevent bacterial infections and promote early osseointegration. The main advantage of the titanium surface treatment method of the study was that its simplicity, low cost, especially its versatility made it a promising anti-infective bone repair material.

Abstract

A series of Eu doped NaBPO (B = Ca, Sr, Ba) phosphors were synthesized by a solid state reaction. The XRD patterns of the obtained phosphors indicate that the Eu doping does not change the phase of the host. The obtained Eu doped NaBPO (B = Ca, Sr, Ba) phosphors exhibit emission bands originating from the 4 f-5 d transitions of Eu ions. The emission spectra of Eu doped NaBPO (B = Ca, Sr, Ba) phosphors also show that the optimum concentrations of Eu in these three hosts all are 5 mol%. The blue shifts can be observed when we compare the emission wavelength of Eu doped NaBPO (B = Ca, Sr, Ba) phosphors. The blue shifts of emission wavelength are induced by the decreasing crystal field splitting of Eu in NaBPO (B = Ca, Sr, Ba) hosts. [ABSTRACT FROM AUTHOR]
