Herein,we report a highly active K-added Ru/MgO catalyst for hydrogen storage into aromatic benzyltoluenes at low temperatures to advance liquid organic hydrogen carrier *** hydrogenation activity of Ru/K/MgO catalysts exhibits a volcano-shaped dependence on the K content at the maximum with 0.02 wt%.This is in good agreement with the strength and capacity of H_(2) adsorption derived from basicity,despite a gradual decrease in the textural property and the corresponding increase in the Ru particle size with increasing the K *** functional theory calculations show that heterolytic hydrogen adsorption properties(strength and polarization)are facilitated up to a specific density of K on the Ru–MgO interface and excessive K suppresses heterolytic H_(2) adsorption by direct interaction between K and hydrogen,assuring the hydrogenation activity and H_(2) adsorption capability of Ru/K/MgO ***,the Ru/K/MgO catalyst,when K is added in an optimal amount,is highly effective to accelerate hydrogen storage kinetics at low temperatures owing to the enhanced heterolytic H_(2) adsorption.

Salicylic acid (SA) plays an important role in plant immune response, including resistance to pathogens and systemic acquired resistance. Two major components, NONEXPRESSOR OF PATHOGENESIS-RELATED GENES (NPRs) and TGACG motif-binding transcription factors (TGAs), are known to mediate SA signaling, which might also be orchestrated by other hormonal and environmental changes. Nevertheless, the molecular and functional interactions between SA signaling components and other cellular signaling pathways remain poorly understood. Here we showed that the steroid plant hormone brassinosteroid (BR) promotes SA responses by inactivating BR-INSENSITIVE 2 (BIN2), which inhibits the redox-sensitive clade I TGAs in Arabidopsis. We found that both BR and the BIN2 inhibitor bikinin synergistically increase SA-mediated physiological responses, such as resistance to Pst DC3000. Our genetic and biochemical analyses indicated that BIN2 functionally interacts with TGA1 and TGA4, but not with other TGAs. We further demonstrated that BIN2 phosphorylates Ser-202 of TGA4, resulting in the suppression of the redox-dependent interaction between TGA4 and NPR1 as well as destabilization of TGA4. Consistently, transgenic Arabidopsis overexpressing TGA4-YFP with a S202A mutation displayed enhanced SA responses compared to the wild-type TGA4-YFP plants. Taken together, these results suggest a novel crosstalk mechanism by which BR signaling coordinates the SA responses mediated by redox-sensitive clade I TGAs.

Objective:The effectiveness of adjuvant treatments for resected gallbladder carcinoma(GBC)has remained unclear due to lack of randomized controlled trials;thus,the aim of present study was to evaluate the role of adjuvant treatments,including chemoradiotherapy(CRT)and/or chemotherapy(CTx),in patients with resected ***:A total of 733 GBC patients who received curative-intent surgical resection were identified in a multi-institutional *** 733 patients,372(50.8%)did not receive adjuvant treatment,whereas 215(29.3%)and 146(19.9%)received adjuvant CTx and CRT,*** locoregional recurrence-free survival(LRFS),recurrence-free survival(RFS),and overall survival(OS)of the adjuvant treatment groups were compared according to tumor stage(stage II *** III–IV).Results:In stage II disease(n=381),the 5-year LRFS,RFS,and OS were not significantly different among the no-adjuvant therapy,CTx,and CRT groups,and positive resection margin,presence of perineural invasion,and Nx classification were consistently associated with worse LRFS,RFS,and OS in the multivariate analysis(P<0.05).For stage III–IV(n=352),the CRT group had significantly higher 5-year LRFS,RFS,and OS than the no-adjuvant therapy and CTx groups(67.8%,45.2%,and 56.9%;37.9%,28.8%,and 35.4%;and 45.0%,30.0%,and 45.7%,respectively)(P<0.05).Conclusions:CRT has value as adjuvant treatment for resected GBC with stage III–IV *** study is needed for stage II disease with high-risk features.

In this paper, we proposed a combined PCA-LPP algorithm toimprove 3D face reconstruction performance. Principal component analysis(PCA) is commonly used to compress images and extract features. Onedisadvantage of PCA is local feature loss. To address this, various studies haveproposed combining a PCA-LPP-based algorithm with a locality preservingprojection (LPP). However, the existing PCA-LPP method is unsuitable for3D face reconstruction because it focuses on data classification and *** the existing PCA-LPP, the adjacency graph, which primarily shows the connectionrelationships between data, is composed of the e-or k-nearest neighbortechniques. By contrast, in this study, complex and detailed parts, such aswrinkles around the eyes and mouth, can be reconstructed by composing thetopology of the 3D face model as an adjacency graph and extracting localfeatures from the connection relationship between the 3D model *** verified the effectiveness of the proposed method. When theproposed method was applied to the 3D face reconstruction evaluation set,a performance improvement of 10% to 20% was observed compared with theexisting PCA-based method.
