Soil salinity is one of the most severe abiotic stress factors threatening agriculture worldwide. hence,particular interest exists in unraveling mechanisms leading to salt tolerance and improved crop plant performance onsaline soils. Barley is considered to be one of the most salinity-tolerant crops, but varying levels of tolerance are wellcharacterized. A proteomic analysis of the roots of two contrasting cultivars （cv. Steptoe and cv. Morex） is *** plants were exposed to a period of 1, 4, 7, or 10 d at 0, 100, or 150mM NaCI. The root proteome was analyzedbased on two-dimensional gel electrophoresis. A number of cultivar-specific and salinity stress-responsive proteins wereidentified. Mass spectrometry-based identification was successful for 74 proteins, and a hierarchical clustering analysisgrouped these into five clusters based on similarity of expression profile. The rank product method was applied to sta-tistically access the early and late responses, and this delivered a number of new candidate proteins underlying salinitytolerance in barley. Among these were some germin-like proteins, some pathogenesis-related proteins, and numerousas-yet uncharacterized proteins. Notably, proteins involved in detoxification pathways and terpenoid biosynthesis weredetected as early responsive to salinity and may function as a means of modulating growth-regulating mechanisms andmembrane stability via fine tuning of phytohormone and secondary metabolism in the root.

The structure [MnmTPP][Me2DCNQI] （TPP = tetraphenylporphinato; Me2DCNQI = 2,5-dimethyl-N,N＇-dicyanoquinonediimine） has been determined from X-ray powder diffraction data. The nonsolvated structure is composed of linear （I-D） chains of alternating [MnmTPP]＋ and ta-[MezDCNQI]＇- with intrachain Mn...Mn separations of 12.83 A, and a Mn-NDcNQI distance of 2.18A. The dihedral angle between the mean Mn（N4）xpp and [MezDCNQI]＇-planes, and the Mn-（N-C）ocNQ1 angle are 84.18° and 143.6°, respectively. [MnInTpP][MezDCNQI] has a Tc of 4.3 K from the 10 hz x（T） data, 2-K coercivity of 5,600 Oe, and 6,300 emuOe/mol remnant magnetization that are reduced from that observed for related materials, and their in- clusion extends the magnetostructural correlation between the intrachain coupling and both the dihedral angle between the mean Mn（N4）xPp and [TCNE]＇-（TCNE --- tetracyanoethylene） planes and Mn-（N-C）Tcr angles. This is in accord with the in- trachain coupling arising from the overlap of the Mnm dz2-1ike singly occupied molecular orbital （SOMO） and the z component of the [TCNE]- π＊（π2＊） SOMO, which increases with decreasing dihedral angle between the mean Mn（N4）xep and [TCNE]＇- planes and Mn-（N-C）TcNE angle.

Ilizarov技术是国际公认的肢体矫形临床治疗方法,但外固定相关的并发症较多。随着时代的发展和进步,在Ilizarov技术基础上形成了第2代肢体矫形技术——体外控制全植入性髓内延长钉。自20世纪80年代首个体外控制全植入性髓内延长钉出现,经过40余年的发展,目前已有超过3种延长机制的体外控制全植入性髓内延长钉,而且通过大量实验研究及临床应用,已经形成了成熟稳定的临床治疗模式,如德国peter ***教授提出的End-Point-First(EPF)方案。与Ilizarov技术相比,体外控制全植入性髓内延长钉在便利性、舒适度、感染风险、软组织损伤、术后疼痛感以及肢体延长可控性方面均有明显优势。目前,国内尚无相关器械及其临床应用,该文主要对体外控制全植入性髓内延长钉的发展、临床治疗理念以及目前国外肢体延长治疗现状进行详细介绍,以期为国内肢体矫形进一步发展提供新思路。

The objective of the study was to investigate the possibility that tandem inclusions of a reducing agent and a protease may advantage chicken-meat production and to ascertain if the established benefits of including sodium metabisulphite in sorghum-based diets extend to wheat-based diets. The study comprised a 2 x 2 x 2 factorial array of treatments in which either nutritionally iso-nitrogenous and isoenergetic wheat-or sorghum-based diets, without and with sodium metabisulphite(2.75 g/kg), without and with protease(1,000 units/kg) were offered to broiler chickens from 7 to 28 days post-hatch. The effects of dietary treatments on growth performance, nutrient utilisation, protein(N) and starch digestibility coefficients and digestive dynamics were determined. A preliminary investigation into the effects of two treatments on concentrations of free amino acids and glucose in the portal circulation was conducted. There was significant feed grain by sodium metabisulphite interactions(P = 0.03 to 0.005) for parameters of nutrient utilisation(AME, ME:GE ratios, N retention, AMEn). For example, sodium metabisulphite inclusions in sorghum-based diets enhanced AME by 0.18 MJ(12.47 versus 12.29 MJ/kg) but depressed AME by 0.43 MJ(11.88 versus 12.31 MJ/kg) in wheat-based diets. There was a linear relationship between starch:protein disappearance rate ratios in the distal ileum with weight gain(r =-0.484; P = 0.0012) indicating that condensed ratios(or absorption of more protein relative to starch) advantaged growth performance. Concentrations of free amino acids in the portal circulation or the post-enteral availability of certain amino acids, including the branched-chain amino acids, methionine, phenylalanine and threonine, were significantly correlated to FCR. For example, threonine concentrations were negatively correlated to FCR(r =-0.773; P = 0.005). Finally, tandem inclusions of sodium metabisulphite and protease in sorghum-based diets may hold merit but it appears that t

In this paper, we present a novel approach for assessing and interacting with surface tracking algorithms targeting video manipulation in postproduction. As tracking inaccuracies are unavoidable,we enable the user to provide small hints to the algorithms instead of correcting erroneous results afterwards. Based on 2D mesh warp-based optical flow estimation, we visualize results and provide tools for user feedback in a consistent reference system, texture space. In this space, accurate tracking results are reflected by static appearance, and errors can easily be spotted as apparent change. A variety of established tools can be utilized to visualize and assess the change between frames. User interaction to improve tracking results becomes more intuitive in texture space, as it can focus on a small region rather than a moving *** show how established tools can be implemented for interaction in texture space to provide a more intuitive interface allowing more effective and accurate user feedback.
