肌节

Objective To investigate the mutation characteristics of paired box homeotic gene 9(PAX9) and mus-cle segment homeobox gene 1(MSX1) of patients with congenital oligodontia.

目的 探讨多数牙先天缺失患者的人类成对盒基因(PAX9)和肌节同源盒基因(MSX1)突变位点，为该疾病的病因学研究提供依据。

Meanwhile, six segments without delayed enhancement and abnormal wall motion before PCI, were found to be hypokinetic postoperate. Four of them were depicted with low signal intensity in first-pass perfusion MR imaging before PCI.

同时发现6段无延迟强化且室壁运动正常的心肌节段在随访后出现收缩运动异常，而4段术前心肌灌注成像呈低信号区。

The motor molecule forms bipolar thick filaments that interdigitate with thinner actin filaments in the saromere, forming the basic contractile unit of muscle.

在所有的分子马达中，关于肌球蛋白的研究最多。肌球蛋白是肌肉收缩的关键成份，由它们形成的双极粗丝在肌节内同肌动蛋白细丝交叉对插，构成一个收缩单元。

Results:In the midpapillary parasternal short-axis view,integrated RFAC time curves showed almost identical patterns between segments,which were line in early systole and depressed in late systole.

结果：乳头肌水平短轴切面不同心肌节段RFAC时间累积曲线有非常相似的形态，心尖四腔切面的曲线虽较乳头肌水平短轴切面稍微离散，但总体的趋势仍相一致。

Results Compared with normal myocardium, the peaks of strain and strain rate curve of ischemic myocardium in systole and EF reduced. The postsystolic shortening wave appeared before operation.

结果 术前缺血节段心肌应变和应变率曲线中应变值和收缩期峰应变率值均小于健康人相应心肌节段并可出现收缩后收缩波；术后经治疗的缺血心肌各指标较术前明显增加，PSS波消失，术后左室射血分数有增加。

Results Compared with normal myocardium, the peaks of strain and strain rate curve of ischemic myocardium in systole and EF reduced. The postsystolic shortening wave appeared before operation. Each index increased and PSS wave disappeared after operation.

结果 术前缺血节段心肌应变和应变率曲线中应变值和收缩期峰应变率值均小于健康人相应心肌节段并可出现收缩后收缩波；术后经治疗的缺血心肌各指标较术前明显增加，PSS波消失，术后左室射血分数有增加。

The parameters of perfusion signal intensity-time curve, including upslope、peak signal intensity, and time to peak signal intensity were analyzed for each segment in different groups.

依据冠状动脉造影结果将不同狭窄程度血管所供心肌节段分为四组，即明显狭窄组(血管狭窄≥75％)、中度狭窄组(血管狭窄在50％～74％)、轻度狭窄组(血管狭窄＜50％)及正常组，分析每一节段心肌灌注信号曲线参数(最大斜率、强化峰值及达峰值的通过时间)并比较组间差异。

The ultrastructure of normal guinea pig papillary muscle cell showing the sarcomere and light dark band were clear, mitochondria and glycogenosome were abundant, and mitochondrial cristae and membrane were clear.

正常豚鼠乳头状肌细胞在透射电镜下显示肌节排列整齐，细胞核周线粒体和糖原颗粒含量非常丰富，且线粒体嵴和膜清晰可见。

The myocardial fibers are beginning to lose cross striations and the nuclei are not clearly visible in most of the cells seen here.

心肌纤维的肌丝肌节结构破坏并且大多数细胞核不清楚，注意许多不规则的较暗的粉红的波浪状的并列的肌纤维。

At 24 h, Ang1 was expressed mainly in the lens, optic cup, mesencephalon, ventral part of hindbrain, and myotomes in the somites, while zfTie2 was mainly expressed in intersomitic vessels including dorsal aorta and axial veins, and sprouting vessels from the dorsal aorta in the trunk. VEGF was expressed mainly in the lens, optic cup, mesencephalon and myotomes in the somites, while zfFlk1 was mainly expressed in intersomitic vessels including dorsal aorta and axial veins, and sprouting vessels from the dorsal aorta in the trunk.

结果从受精卵胚胎发育第12小时可见血管内皮细胞生长因子和血管发生素1及其相应受体flk1和Tie2的表达；在受精卵胚胎发育的第16小时，血管内皮细胞生长因子和血管发生素1主要在头部和尾部胚芽表达；第24小时在眼球、视窝、中脑、后脑的腹前侧和肌节中表达，Tie2和Flk1主要在肌间背部动脉血管、躯干新生血管芽和轴向静脉中表达。

Lugalbanda was a god and shepherd king of Uruk where he was worshipped for over a thousand years.

Lugalbanda 是神和被崇拜了一千年多 Uruk古埃及喜克索王朝国王。

I am coming just now,' and went on perfuming himself with Hunut, then he came and sat.

我来只是现在，'歼灭战perfuming自己与胡努特，那麼，他来到和SAT 。
