5%). Additionally, the cost of extracted herbal drugs and traditional Chinese medicine comprised ϳ17.6% of the drug expense. Higher education level, noninsured status, longer disease duration, more extraarticular manifestations, and higher Health Assessment Questionnaire score independently predicted higher total costs. Conclusion. Our results provide the first study of costs of RA in China. This study not only demonstrates the economic burden of RA, but also identifies the predictors that could be interventional factors to reduce the societal costs of RA in China.
A 3d–4f luminescent metal–organic
framework (MOF), [Tb2(Cu8I8)(C12H8NO2)6(H2O)4]·5C4H8O2 (4), and three analogues {[La2(Cu8I8)(C12H8NO2)6(C4H8O2)2(H2O)2]·3C4H8O2·2H2O (1), [Ce2(Cu8I8)(C12H8NO2)6(H2O)4]·5C4H8O2 (2), and [Eu2(Cu8I8)(C12H8NO2)6(H2O)4]·5C4H8O2 (3)},
were self-assembled from copper(I) halide clusters and lanthanide
metal ions with an organic linker [3-(pyridin-4-yl)benzoic acid] under
solvothermal conditions. Compound 4 with high quantum
yield (Φ = 68%) exhibits reversible luminescence behavior, accompanying
the removal and recovery of guest molecules (1,4-dioxane). Because
of the unique porous structure and dual luminescent centers of compound 4, it can efficiently differentiate benzene series with different
sizes and provide readouts in corresponding optical signals. Furthermore,
it also can unambiguously discriminate the isomers, homologues, and
other small molecules with similar structural motifs from one another.
The luminescent color of the MOF sensor in different guest solvents
has obvious changes that can be clearly distinguished by the naked
eye. This multicolor luminescence originates from emissions of the
dual luminescent centers, and the emissions have shifted, enhanced,
weakened, or quenched to different degrees.
The Gully Land Consolidation Project (GLCP) was launched to create more arable land by excavating soil from the slopes on both sides of gullies, combined with simultaneous comprehensive gully prevention and control measures. The purpose of the GLCP is to increase crop production and reduce soil erosion to achieve ecological and agricultural sustainability. In this study, we assess the effects of the GLCP on soil erosion and crop production by studying the BaoChengGou Watershed in the Loess Plateau, primarily by means of high spatial-resolution satellite images (taken by the GF-1 and ZY-3 satellites) combined with the InVEST model and field investigations. Sloping cropland, sparse forestland, and natural grassland are the main land use types in the study area. After implementing the GLCP, consolidated land in the cropland increased by 7.35%, an increase that has come largely at the expense of grassland and forestland. The GLCP has markedly reduced soil erosion in the BaoChengGou Watershed, especially in the sense that soil erosion intensity was also reduced significantly in the project region on the whole, despite intensifying in certain places, such as excavated slopes; furthermore, it has improved crop yields in the study area by 10.9%. Comprehensive measurement shows the GLCP to be scientific, reasonable, and clearly efficacious. This study presents findings regarding the positive significance of the GLCP in promoting ecological and agricultural sustainability in the Loess Plateau.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
