Spinal cord injury （SCI） is a devastating condition that not only results in a loss of motor functions but also severe autonomic dysfunctions （Krassioukov and Claydon, 2006）. Autonomic dysreflexia （AD） is a life threatening episode of tran- sient hypertension that occurs up to 30x/day （1 Ix/day on average） in those with cervical or high thoracic SCI （Hubli et al., 2015）. Most common triggers of AD are from stimuli such as a full bowel and/or bladder, or sexual arousal （Teasell et al., 2000）. Penile vibrostimulation （PvS） is a clinical pro- cedure for sperm retrieval used for the purpose of family planning or fertility assessment that unfortunately iatrogenically induces episodes of AD （Elliott, 2006）. Recently, we published a clinical trial highlighting that prazosin may be a viable option for treating AD secondary to PvS （Phillips et al., 2014）.

The aim of this study is to detect whether the quantitative textural features of optical coherencetomography angiography (OCTA) images can be used to detect the eyes in the early stage ofdiabetic retinopathy (DR) from eyes with diabetes and no DR (NDR). Textural features includingfractal dimension, contrast, correlation, entropy, energy, and homogeneity were calculatedfrom the OCTA images. The Student's t-test was performed to identify the textural featuresthat can be able to detect DR in the early stage. The area under the receiver operating characteristic(AUROC) curves, sensitivity, and specicity were calculated between the study *** results indicated that the fractal dimension in ICP and SvP and the correlation in SvCshowed the statistical signicance between mild NPDR patients and NDR patients. The ROCanalysis results showed that the AUROC of the fractal dimension in ICP was 0.736 with 0.773sensitivity and 0.700 specicity. The cuto® point in ICP was 2.616. The OCTA-based fractaldimension was able to discriminate diabetic eyes with early retinopathy from healthy and NDRwith higher sensitivity and specicity. The OCTA-based correlation showed the power to differentiatethe mild NPDR eyes from the normal healthy and diabetic eyes. These results suggestthat texture-based features of OCTA have the potential to assist in the assessment of therapeuticinterventions to prevent early DR in diabetic subjects.

Taking into account the non separable solution for the quantum problem of the motion of a charged particle in a flat surface of lengths Lx and Ly with transversal static magnetic field B and longitudinal static electric field E, the quantum current, the transverse (Hall) and longitudinal resistivities are calculated for the state n = 0 and j = 0. We found that the transverse resistivity is proportional to an integer number, due to the quantization of the magnetic flux, and longitudinal resistivity can be zero for times t >> LxB/cE. In addition, using a modified periodicity of the solution, a modified quantization of the magnetic flux is found which allows to have IQHE and FQHE of any filling factor of the form v = k/l, with k, l ∈Z.

土壤镉污染严重影响作物的产量和品质,并通过食物链威胁人类健康。对于受轻度或中度镉污染的土壤,培育和种植耐镉且食用器官低积累作物基因型/品种,是有效利用自然资源和保证农产品安全生产的重要途径之一。玉米(Zea mays L.)是目前世界上产量最高的粮食作物。本研究在分析比较95个玉米基因型(自交系)籽粒镉含量筛选获得籽粒镉积累不同玉米基因型的基础上,分析了镉胁迫对不同籽粒镉积累基因型玉米生长、植物激素等的影响及基因型差异,并通过比较转录组分析,探讨了镉耐性与低积累的相关基因。主要研究结果如下:1.玉米籽粒镉低积累基因型筛选分析评估95份玉米基因型(自交系)籽粒镉含量,筛选籽粒镉低积累基因型。连续两年的田间试验在浙江大学长兴农业试验站进行,分析测定籽粒镉含量,结果表明,相同栽培条件下,95个玉米基因型籽粒镉含量平均为0.013 mg kg DW,变化范围为0.001-0.06 mg Cd kgDW,基因型间差异显著。连续两年的试验结果显示,籽粒镉含量基因型差异的变化趋势完全一致,其中籽粒镉含量最低和最高的分别为:基因型L42、L15和L51、L63。此外,95份基因型籽粒铬、铁、锰、锌和铜等微量元素含量基因型间也存在显著差异,相关性分析结果显示,籽粒Cd与Mn、Cu含量呈显着正相关。2.镉胁迫对两个不同籽粒镉积累玉米基因型生理特性的影响及基因型差异以筛选获得的籽粒镉低/高积累基因型L63/L42为材料,水培实验,研究了5μM Cd胁迫对玉米生长与生理的影响和基因型差异。结果表明,L63对镉毒害的耐性显著强于L42。与对照相比,5μM Cd胁迫显着降低L42的株高、根/茎叶的鲜重和干重;但L63植株的上述生长参数几乎没有受影响。与L42相比,L63幼苗根中的镉浓度较高,而茎叶中的镉浓度却相对较低。镉胁迫导致L63和L42茎叶中Mn含量较对照显着降低22%和33%,L63茎叶中Fe含量显着降低22%。此外,植物激素响应24h的5μM Cd胁迫存在极显著的基因型差异,与对照相比,L42中的ABA含量和乙烯(ET)释放速率显着增加;而L63中的GA3、JA和ET分别显着增加;同时,5μM Cd胁迫条件下,L63的ABA、ET和GA3低于L42。叶片和根系超微结构观察结果显示,镉胁迫显著导致L42细胞结构的损伤,但对L63没有显著影响。3.两个不同籽粒镉积累玉米基因型对镉胁迫响应的转录组比较以耐镉-籽粒低积累和镉敏感-高积累基因型L63和L42为材料,水培镉胁迫试验,转录组分析,比较基因表达响应5μM Cd胁迫的基因型差异。与对照相比,镉胁迫诱导上调和下调的基因:L42中分别有268和300个,而L63中分别有86和26个。鉴定到83个与低Cd积累或Cd耐性相关的候选基因(这些基因在镉胁迫下在L63中的表达显著上调,但在L42中表达不变或下调),主要包括自噬相关-8d、ATP硫酸酯酶3、ABC转运蛋白、锌转运蛋白和RING型锌指结构域超家族蛋白。这些基因分别属应激反应、转运、蛋白质合成和降解、转录、信号转导以及细胞分裂和生长相关。基于这些差异表达基因,提出了一个调控示意图,结果显示,镉耐性与低积累相关的关键基因主要涉及细胞壁代谢、金属转运、液泡区隔化、活性氧清除和ATP产生。

文章通过考察持续体标记＂着＂各类句式在越南语中的对应形式,发现越南语只有表示进行体的副词＂＂,没有类似于＂着＂的持续体标记。越南语在表示动作或状态的持续时,动词后通常不带任何时体标记,或使用＂动词＋dang＂表达。学习者容易出现回避使用＂着＂的情况;由于对＂着＂使用条件说明不清楚,学习者也出现在不该用＂着＂的时候误加＂着＂、用＂着＂误代补语、滥用＂v1着v2＂等情况。汉语＂v1着v1着,v2＂结构用法特殊,使用语境要求高,越南语对应形式多样,学习者容易出错。

The practical significance of the established generalized differential formula-tion of the first law of thermodynamics (formulated for the rotational coor-dinate system) is evaluated (for the first time and for the mesoscale oceanic eddies) by deriving the general (viscous-compressible-thermal) and partial (incompressible, viscous-thermal) local conditions of the tidal maintenance of the quasi-stationary energy and dissipative turbulent structure of the mesoscale eddy located inside of the individual fluid region of the ther-mally heterogeneous viscous (compressible and incompressible, respective-ly) heat-conducting stratified fluid over the two-dimensional bottom topog-raphy characterized by the horizontal coordinate x along a horizon-tal axis X. Based on the derived partial (incompressible) local condition (of the tidal maintenance of the quasi-stationary energy and viscous-thermal dis-sipative turbulent structure of the mesoscale eddy) and using the calculated vertical distributions of the mean viscous dissipation rate per unit mass and the mean thermal dissipation rate per unit mass in four regions near the observed mesoscale (periodically topographically trapped by nearly two-dimensional bottom topography h(x) eddy located near the northern region of the Yamato Rise in the Japan Sea, the combined analysis of the energy structure of the eddy and the viscous-thermal dissipative structure of turbulence is presented. The convincing evidence is presented of the tidal mechanism of maintenance of the eddy energy and viscous-thermal dissipa-tive structure of turbulence (produced by the breaking internal gravity waves generated by the eddy) in three regions near the Yamato Rise subjected to the observed mesoscale eddy near the northern region of the Yamato Rise of the Japan Sea.
