查询词典 ALS

High signal on T1 weighted images in the intracranial corticospinal tract may be specific for ALS and may correlate with the severity of the upper motor neurone lesions.

T1像上颅内皮质脊髓束的高信号改变对ALS而言可能具有特异性，并可能与上运动神经元症状体征的严重程度存在关联性。

Segawa[10] also demonstrated high signal in the intracranial corticospinal tract on T1-weighted images in patients with ALS but not in normal and disease controls, as in the present study.

ALS患者在T1像上于颅内皮质脊髓束走行区可见高信号病灶，但正常人、其他神经疾病患者在T1像上却未见此改变。

In the present study, high signal in the corticospinal tract on T2-(16 of 21) and PD-(10 of 21) weighted images and low signal in the motor cortex on T2 weighted images (12 of 21) were seen frequently in patients with ALS.

在此研究中，ALS患者在T2像上、PdWI像上于脑部皮质脊髓束走行区常可见高信号病灶，在T2像上于运动皮质区常可见低信号病灶。

In addition, five patients with ALS with severe upper motor neurone signs such as spastic paraparesis showed high signal in the intracranial corticospinal tract on T1-weighted images as well as on T2- and PD-weighted images.

另外，5例表现出严重的上运动神经元症状体征的ALS患者，在T1、T2、PdWI这3像上，都于颅内皮质脊髓束走行区表现出高信号病灶。

To assess this hypothesis, we studied sleep characteristics in 21 patients with ALS, stratified according to the presence or absence of diaphragmatic dysfunction.

本文对这一假设进行验证。方法：研究21例ALS患者的睡眠特征，依据有无膈肌功能紊乱进行分析。

Methods Fifteen patients with clinically probable or definite ALS according to the El Escorial criteria and 12 (age and sex-matched) healthy control subjects were studied with the use of DTI.

方法运用GE Signa3.0T磁共振成像系统，对15例临床确诊及拟诊的ALS患者和12例性别、年龄相当的正常对照者进行了全脑DTI扫描。

Single-voxel 1H-MRS was carried on the precentral gyri in 110 patients with ALS and 24 patients with lower motor neuron syndrome compared with 89 healthy controls.

虽然一些影像技术如MRI已用于ALS研究，但其上运动神经元受损的范围和程度仍难以用传统神经影像或电生理方法定量化测量。

A full-length cDNA encoding sucrose: sucrose 1-fructosyltransferase from Lactuca sativa was inserted into pCAMBIA1300-als under the control of the CaMV 35S promoter. This plasmid was used for Agrobacteriummediated tobacco leaf disc transformation. Transgenic plants were analyzed by PCR and Southern blotting. 1-SST gene expression was confirmed by RT-PCR.

将从莴苣中克隆的1-SST基因重组到pCAMBIA1300-als中，构建了在CaMV 35S启动子调控下的植物表达载体，利用农杆菌介导的叶盘转化法将1-SST基因导入烟草中，PCR和Southern杂交检测表明获得了转基因植株，RT-PCR结果表明该基因在烟草中正常表达。

This was not seen in other patients with ALS whose upper motor neurone signs were not so manifest, nor in controls.

但上运动神经元症状体征不明显的ALS患者、正常人、其他神经疾病患者，却没有在T1、T2、PdWI这3像上都出现高信号改变。

This was not seen in other patients with ALS whose upper motor neurone signs were not so manifest, nor in controls.

但上运动神经元症状体征不明显的ALS患者、正常人、其他神经疾病患者，却没有在T1、T2、PdWI这3像上均都出现高信号改变。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
