3Single-atom heterogeneous catalysts based on distinct carbon nitride scaffolds显示文摘Carbon nitrides integrating macroheterocycles offer unique potential as hosts for stabilizing metal atoms due to their rich electronic structure. To date, only graphitic heptazine-based polymers have been studied.Here, we demonstrate that palladium atoms can be effectively isolated on other carbon nitride scaffolds including linear melem oligomers and poly(triazine/heptazine imides). Increased metal uptake was linked to the larger cavity size and the presence of chloride ions in the polyimide structures. Changing the host structure leads to significant variation in the average oxidation state of the metal, which can be tuned by exchange of the ionic species as evidenced by X-ray photoelectron spectroscopy and supported by density functional theory. Evaluation in the semi-hydrogenation of 2-methyl-3-butyn-2-ol reveals an inverse correlation between the activity and the degree of oxidation of palladium, with oligomers exhibiting the highest activity. These findings provide new mechanistic insights into the influence of the carbon nitride structure on metal stabilization.Zupeng Chen Evgeniya Vorobyeva Sharon Mitchell Edvin Fako Núria López Sean M.Collins Rowan K.Leary Paul A.Midgley Roland Hauert Javier Pérez-Ramírez 2018National Science Review2018,5,5:4
4社区人群血压和颈动脉血流速度与脑容量和脑小血管病的关系显示文摘做脑磁共振成像(magnetic resonance imaging,MRI)经常发现脑小血管病(cerebral small vessel disease,CSVD)。研究已证明高血压和低颈动脉血流速度与脑血管病存在关联。但是,这种关联与脑容量和CSVD的相关性仍有待研究。本文纳入基于社区的I-Lan纵向衰老研究(I-Lan longitudinal aging study)中年龄≥50岁的成年人721例进行分析,采用多普勒超声测量颈总动脉和颈内动脉血流速度,包括收缩期峰值血流速度(peak systolic velocity,PSV)和舒张终末期血流速度(end-diastolic velocity,EDV)。袁源(摘译) 郑武洪(审校) Chuang SY Wang PN Chen LK Chou KH Chung CP Chen CH Mitchell GF Pan WH Cheng HM 2021中华高血压杂志2021,29,9:4
5A Highly Efficient Agrobacterium-Mediated Method for Transient Gene Expression and Functional Studies in Multiple Plant Species显示文摘Although the use of stable transformation technology has led to great insight into gene function,its application in high-throughput studies remains arduous.Agro-infiltration have been widely used in species such as Nicotiana benthamiana for the rapid detection of gene expression and protein interaction analysis,but this technique does not work efficiently in other plant species,including Arabidopsis thaliana.As an efficient high-throughput transient expression system is currently lacking in the model plant species A.thaliana,we developed a method that is characterized by high efficiency,reproducibility,and suitability for transient expression of a variety of functional proteins in A.thaliana and 7 other plant species,including Brassica oleracea,Capsella rubella,Thellungiella salsuginea,Thellungiella halophila,Solanum tuberosum,Capsicum annuum,and N.benthamiana.Efficiency of this method was independently verified in three independent research facilities,pointing to the robustness of this technique.Furthermore,in addition to demonstrating the utility of this technique in a range of species,we also present a case study employing this method to assess protein–protein interactions in the sucrose biosynthesis pathway in Arabidopsis.Youjun Zhang Moxian Chen Beata Siemiatkowska Mitchell Rey Toleco Yue Jing Vivien Strotmann Jianghua Zhang Yvonne Stahl Alisdair R.Fernie 2020Plant Communications2020,1,5:4
6Computed tomography pulmonary angiography using a 20% reduction in contrast medium dose delivered in a multiphasic injection显示文摘AIM To evaluate the feasibility of reducing the dose of iodinated contrast agent in computed tomography pulmonary angiography(CTPA). METHODS One hundred and twenty-seven patients clinically suspected of having pulmonary embolism underwent spiral CTPA, out of whom fifty-seven received 75 mL and the remaining seventy a lower dose of 60 mL of contrast agent. Both doses were administered in a multiphasic injection. A minimum opacification threshold of 250 Hounsfield units(HU) in the main pulmonary artery is used for assessing the technical adequacy of the scans. RESULTS Mean opacification was found to be positively correlated to patient age(Pearson's correlation 0.4255, P < 0.0001) and independent of gender(male:female, 425.6 vs 450.4,P = 0.34). When age is accounted for, the study and control groups did not differ significantly in their mean opacification in the main(436.8 vs 437.9, P = 0.48),left(416.6 vs 419.8, P = 0.45) or the right pulmonary arteries(417.3 vs 423.5, P = 0.40). The number of sub-optimally opacified scans(the mean opacification in the main pulmonary artery < 250 HU) did not differ significantly between the study and control groups(7 vs 10).CONCLUSION A lower dose of iodine contrast at 60 mL can be feasibly used in CTPA without resulting in a higher number of sub-optimally opacified scans.Mitchell Chen Gaith Mattar Jamal A Abdulkarim 2017World Journal of Radiology2017,9,3:2
