Preferential orientation control of metal—organic framework(MOF) films is advantageous for maximizing pore uniformity and minimizing grain-boundary defects. Nonetheless, the preparation of MOF films with both in-plane and out-of-plane orientations remains a grand challenge. In this study, we reported the preparation of three-dimensionally oriented MIL-96 layers through combining morphology control of MIL-96 seeds with addition of polyvinylpyrrolidone surfactants and arachidonic acids. The three-dimensionally oriented MIL-96 film was readily obtained through in-plane epitaxial growth. It is anticipated that the aforementioned protocol can be effective for obtaining diverse MOF films with a three-dimensionally oriented organization.

目的系统评价综合保温护理措施对患者术中体温及临床指标的影响。方法检索中国知网、万方数据知识服务平台、维普数据库、PubMed、EMbase、Cochrane Library等数据库,纳入术中采取保温护理措施的随机对照试验。提取数据并进行文献质量评价后,采用RevMan 5.4软件对符合标准的文献进行Meta分析。结果共纳入10篇文献,包含1035例患者。Meta分析结果显示,试验组(实施综合保温护理措施)患者的术中体温明显高于对照组(实施常规护理保温措施),术后低体温发生率、寒战发生率均低于对照组,术后肾上腺素水平和去甲肾上腺素水平均低于对照组(均P0.05)。结论相比于常规护理保温措施,采取综合保温护理措施可以改善术中不同时期体温,预防术中低体温及寒战的发生,维持应激性指标水平。

Oxalate is an organic dicarboxylic acid that is a common component of plant *** kidneys are essential organs for oxalate excretion,but excessive oxalates may induce kidney *** microtubule associated homolog 2(JPT2)is a critical molecule in Ca^(2+)mobilization,and its intrinsic mechanism in oxalate exposure and kidney stones remains *** study aimed to reveal the mechanism of JPT2 in oxalate exposure and kidney *** approaches were used to control JPT2 expression in cells and mice,and the JPT2 mechanism of action was analyzed using transcriptomics and untargeted *** results showed that oxalate exposure triggered the upregulation of JPT2,which is involved in nicotinic acid adenine dinucleotide phosphate(NAADP)-mediated Ca^(2+)*** analysis revealed that cell adhesion and macrophage inflammatory polarization were inhibited by JPT2 knockdown,and these were dominated by phosphatidylinositol 3-kinase(PI3K)/AKT signaling,*** metabolomics indicated that JPT2 knockdown inhibited the production of succinic acid semialdehyde(SSA)in ***,JPT2 deficiency in mice inhibited kidney stones *** conclusion,this study demonstrates that oxalate exposure facilitates kidney stones by promoting crystal-cell adhesion,and modulating macrophage metabolism and inflammatory polarization via JPT2/PI3K/AKT signaling.

A common view on meridional deflection of eddy propagation is poleward for cyclones and equatorward for anticyclones. This widely accepted polarity-sensitive pattern has been increasingly undermined given that it is systematically violated on both zonal and regional scales as recently reported. Here, we approach the problem by exploring these violations in terms of eddy effects of spatiotemporal geostrophy, thermal fading, and flow dragging, yielding the following main conclusions.(1) The polarity-dependent deflection discrepancy is a pseudo feature resulting from a biased fit to the normalized eddy tracks which are spatially asymmetric(though azimuthally symmetric) between the two signs;Instead, the primary pattern of eddy deflection appears to be geographically correlated and polarity independent.(2) Geostrophic adjustment plays a critical role in defining the meridional movement of an eddy. Specifically, a consistent poleward(equatorward) trajectory bending of spatially(temporally) ageostrophic eddies is observed irrespective of their polarity.(3) The mechanism of eddy deflection is also determined by its zonal propagation direction. Westward propagating eddies are substantially affected by thermal fading, while opposite ones by flow dragging. A realistic and comprehensive understanding of eddy deflection mechanisms serves as a significant contribution to the prediction of eddy trajectory, and the protection of ocean environment.
