Abstract

Air pollution due to fi ne dust (FD) has become a global concern. Industrial effluents and traffic emissions combined with naturogenic sources influence this issue, which particularly impacts the East Asia region. Health concerns caused by this form of pollution include respiratory disorders. The development of anti-inflammatory agents requires an understanding of the underlying mechanism. This study investigated the impact of FD on RAW 264.7 macrophages and sonication-assisted water extract of soft coral Dendronephthya gigantea (DGE) as a potent anti-fi ne dust agent. Cytoprotective effects using MTT and NO production inhibition using the Griess assay were assessed. ELISA, western blotting, and RT-qPCR techniques were used to evaluate multiple molecular mediators involved in the inflammatory pathway. It was observed that iNOS, COX-2, and PGE2, including pro-inflammatory cytokines (TNF-α, IL-1β, and IL-6), were downregulated in a dose-dependent manner by DGE treatment. DGE inhibited the inflammatory responses initiated through FD by suppressing MAPK signaling in RAW 264.7 macrophages. This study provides insight into the protective mechanisms against FD, and suggests that D. gigantea could be a valuable, low-cost source of protein for potential use in the cosmeceutical and pharmaceutical sectors.

28. Flux Pinning Mechanism in BaSnO3-Added GdBa2Cu3O7-x Films with Different Thickness.

Abstract

Types of flux pinning mechanism in pure and BaSnO3 (BSO)-added GdBa2Cu3O7-x (GdBCO) superconducting films have been determined by using the Dew-Hughes model. We have found that as the BSO content increases up to 4 wt%, dominant pinning mechanism of GdBCO films has changed from normal surface pinning due to intrinsic linear defects to normal point pinning by BSO addition. Careful analysis on the scaling of the flux pinning for the 4 wt% BSO-doped GdBCO films with various film thicknesses revealed that the pinning mechanism came from the hybrid pinning of two kinds of pinning types. In addition to the normal point pinning by BSO addition, another type of Δκ-pinning was observed to be prominent in the thinner films in low magnetic field region as normal point pinning was deteriorated. Through the EXAFS analysis, it was found that the Δκ-pinning is possibly originated from the oxygen deficiency in localized position. These results suggested that film thickness directly affects the flux pinning mechanism of the BSO-doped GdBCO films, and in the application point of view, an optimization of the film thickness may be crucial to operate normal point pinning induced by BSO addition.

Abstract

The effect of K substitution on the local atomic structure of polycrystalline Bi1.6Pb0.4Sr2−xKxCa2Cu3O10+δ samples (BSCCO, x = 0, 0.02, 0.06, and 0.10) has been investigated. Unlike in other cases of alkaline substitution, the transition temperature Tc of the K-substituted BSCCO samples decreased systematically with increasing K content. Such decreasing Tc behavior supposedly originates from changes in the local structure of the BSCCO system. Analysis of extended x-ray absorption fine structure (EXAFS) data measured at both the Cu K-edge and Sr K-edge revealed that, as the K content was increased, the Cu–O and Cu–Sr bonds systematically extended, while the Sr–O bond distance gradually reduced. The corresponding mean-square relative displacement (MSRD), which represents the average local distortion, showed large alteration in both the CuO2 and SrO planes. Local atomic displacement due to K substitution seemed to weaken the interaction between the conduction layer and spacer layer, resulting in a drastic decrease of the Tc values. Overall, these experimental results provide important information to understand the correlation between the superconductivity and local structure of K-substituted BSCCO. [ABSTRACT FROM AUTHOR]

Abstract

Carbapenem-resistant Escherichia coli (CRE) with a multidrug resistant phenotype was isolated from four clinically ill dogs treated with meropenem in different local animal hospitals between 2017 and 2019. IncX3-type plasmids of ca. 46 kb in size carrying blaNDM-5 were present in all CRE strains and their transconjugants. High genetic similarity (>90%) by PFGE analysis was observed among the CRE strains, which were identified as ST410.To the best of our knowledge, blaNDM-5-producing E. coli ST410 clones are emerging sporadically in companion dogs treated with meropenem. The spread of Enterobacteriaceae harboring the NDM-5 gene in companion animals can pose a threat to public health; therefore, extensive monitoring in veterinary hospitals using carbapenem and careful antibiotic use are crucial for managing and monitoring these resistant strains.
