Abstract

We report on the structural and electrical properties of phosphorous-doped ZnS x O1− x films grown by radiofrequency magnetron sputtering. The band gap decreased with increasing sulfur composition in phosphorus-doped ZnS x O1− x films because of the band bowing effect. The conductivity of phosphorus-doped ZnS x O1− x films changed from n-type to p-type, and the p-type doping efficiency of phosphorus in ZnO was increased as the sulfur content in phosphorus-doped ZnS x O1− x was increased.

86. M13 bacteriophage-based high-sensitivity Fabry-Pérot etalon for detecting humidity and volatile organic compounds.

Abstract

Various sensor applications have been developed for protection against hazardous environments, and research on functional materials to enhance performance has also been pursued. The M13 bacteriophage (M13) has found utility in sensor applications like disease diagnosis and detection of harmful substances due to its potential for controlling interaction with target substances through adjustments in electrochemical and mechanical properties via genetic engineering technology. However, while optimizing reactivity or binding affinity between M13 and target materials is crucial for sensor performance enhancement, precise dynamic measurement methods for this were lacking. This study demonstrates the application of an M13-based dynamic actuator in a Fabry-Pérot etalon (M13-FPE) as a spacer for precise measurement of humidity and reactivity to volatile organic compounds (VOCs). The transmission spectrum is optimized by adjusting the reflectance and cavity gap size (d M13 ) of the two mirrors comprising the M13-FPE, and changes are measured in a rainbow-color-dotted (RCD) pattern using a customized spectrometer. Utilizing the peak wavelengths of the RCD pattern, the change in d M13 is dynamically and precisely measured, revealing approximately 3% and 0.3% swelling for ethanol and isopropyl alcohol, respectively. M13 demonstrates binding affinities of 827 ppb and 158 ppb for ethanol and isopropyl alcohol, respectively, with its low reactivity measured precisely, exhibiting an error of 0.03 nm using the peak wavelength change rate.

87. Oxidative balance scores in Korean adults are associated with periodontitis.

Author

Abstract

Background: The Oxidative Balance Score (OBS) is a comprehensive metric that assesses the state of a person's oxidative balance. This study aimed to investigate the relationship between the oxidative balance score and moderate and severe periodontitis in a representative sample of Korean adults., Methods: Healthcare big data from the 7th Korea National Health and Nutrition Examination Survey (2016-2018) was used, and 16,489 adults aged ≥19 years were included. Multivariate logistic regression analysis was performed to investigate the effect of sex-specific oxidative balance scores on periodontitis., Results: In comparison with participants with a lower oxidative balance score, those with a higher oxidative balance score had a lower incidence of moderate and severe periodontitis (p < 0.05). After adjusting for covariates, the oxidative balance score was negatively associated with moderate (odds ratio [OR] = 0.952; 95% confidence interval [CI]: 0.934-0.971) and severe (OR = 0.958; 95% CI: 0.931-0.986) periodontitis; however, the result was not significant for severe periodontitis in women's (OR = 0.975; 95% CI: 0.934-1.018). Our study showed a statistically significant association between OBS and moderate and severe periodontitis, the small effect size should be interpreted with caution., Conclusions: The oxidative balance score was associated with moderate and severe periodontitis in Korean adults. Therefore, managing this score may help reduce the risk of periodontitis., (© 2024 American Academy of Periodontology.)

Abstract

[reaction: see text] Enantioselective synthesis of 3, a revised structure for clavosolide A, was completed. Both (1)H and (13)C NMR spectra of the natural and synthetic compounds were identical, and optical rotation measurements identified the absolute configuration of the natural clavosolide A as [corrected] 3.
