研究高负荷间歇运动对自发性伸指肌腱断裂的修复性能,将某医院患有自发性伸指肌腱断裂的78位患者作为研究对象,随机将其划分成高负荷间歇运动组和对照组,对照组在实验期间不进行任何运动,高负荷间歇运动组在功率自行车上进行高负荷间歇运动。长期进行高负荷间歇运动后,运动组的IGF-1mRNA表达与对照组相比差异具有显著性,运动组自发性伸指肌腱断裂患者指关节活动评定结果明显优于未进行高负荷间歇运动的患者,且握力明显增加。说明高负荷间歇运动能够提高自发性伸指肌腱断裂患者肌力与手部的整体功能,能够提高自发性伸指肌腱断裂患者的修复性能。 相似文献

Though massive efforts have been devoted to exploring Br-based batteries, the highly soluble Br2/Br3− species causing rigorous “shuttle effect”, leads to severe self-discharge and low Coulombic efficiency. Conventionally, quaternary ammonium salts such as methyl ethyl morpholinium bromide (MEMBr) and tetrapropylammonium bromide (TPABr) are used to fix Br2 and Br3−, but they occupy the mass and volume of battery without capacity contribution. Here, we report an all-active solid interhalogen compound, IBr, as a cathode to address the above challenges, in which the oxidized Br0 is fixed by iodine (I), thoroughly eliminating cross-diffusing Br2/Br3− species during the whole charging and discharging process. The Zn||IBr battery delivers remarkably high energy density of 385.8 Wh kg−1, which is higher than those of I2, MEMBr3, and TPABr3 cathodes. Our work provides new approaches to achieve active solid interhalogen chemistry for high-energy electrochemical energy storage devices. 相似文献

The fixing number of a graph G is the minimum cardinality of a set S⊂V(G) such that every nonidentity automorphism of G moves at least one member of S, i.e., the automorphism group of the graph obtained from G by fixing every node in S is trivial. We provide a formula for the fixing number of a disconnected graph in terms of the fixing numbers of its components and make some observations about graphs with small fixing numbers. We determine the fixing number of a tree and find a necessary and sufficient condition for a tree to have fixing number 1. 相似文献

Abstract A fluorimetric procedure for Ag+ determination in aqueous solutions was developed based on the ion association complex formed from the reaction between AgI- 2 and the brilliant green cation and its strong fluorescence (λexc 256 nm, λem 521 nm). Silver ions could be determined satisfactorily in the range of 0-100 μgAg+/L. Optimum conditions for complex formation and measurement of fluorescence intensity were: pH = 3.0; concentrations of brilliant green and KI, 15 and 100 mg/L, respectively; time, within 15 min after complex formation. The method proved successful in determing Ag+ in photography fixing solutions and the results agreed satisfactorily with those obtained using a standard Atomic Absorption Spectrometry method. 相似文献

Fast‐staining protocols based on the use of Coomassie blue dye for SDS‐PAGE separated proteins, represent a quick and simple solution for protein visualization. It has been shown however, that in some cases a phenomenon of missing spots or spot discoloration may be observed in the proteome pattern when the standard fast‐staining protocol is used. In this work, it is demonstrated that this occurrence is affected by the biological variability of samples, and therefore, cannot be observed in all samples. Moreover, it is demonstrated that the phenomenon is manifested exclusively in nonfixed gels, and that including a fixation step into the fast‐staining protocol prevented this phenomenon. In conclusion, it has been demonstrated that standard Coomassie blue dye based fast staining for SDS‐PAGE resolved proteins is affected by the biological variability of samples in nonfixed gels. 相似文献

采用高固色率的双活性基M型活性染料对速生人工林木材进行染色,均有很好的易染性和渗透性以及较高的上染率。利用不同种类固色剂对活性染料染色单板进行处理,利用分光光度法,分别测定未经和经固色剂处理的活性染料染色单板热水浸泡液的分光光度值,可知分别经3种环保型固色剂处理后的活性染料染色单板的耐水色牢度均有不同程度的提高,其中以NRT处理过的染色单板的耐水色牢度最佳。 相似文献
