查询词典 yolk sac

In this paper, an escherichia coli-saccharopolyspora erythraea shuttle vector containing the erya promoter region was constructed using the enhanced green fluorescent protein gene as a reporter. the shuttle plasmid was transformed into sac.erythraea a226 and streptomyces lividans jt46 by peg mediation, respectively. fluorescence microscopy confirmed that the egfp was expressed in both strains.

本文克隆了erya基因的启动子perya，以绿色荧光蛋白基因为报告基因，构建了大肠埃希菌-糖多孢红霉菌穿梭型质粒。peg介导原生质体转化法将穿梭型质粒分别转入糖多孢红霉菌a226与变铅青链霉菌jt46，荧光显微镜检测发现，此启动子在两菌株中都具有功能。

That by the end of November last pregnancy, 34 days in the way of life has done a night's dream, the result is a stomach ache for 20 minutes, when the doctor is afraid of ectopic pregnancy or threatened abortion, let me stay Baotai results, although the play HCG and progesterone of the needle, but that value has been reduced, B-have not seen extrauterine intrauterine pregnancy sac, and later on January 7 (52 days is about the time) see red on the spontaneous abortion, and did not do Qing, because doctors say the stream clean, do not need to do Qinggong, my last time is very short it?

去年11月底那次怀孕，也是在34天的样子，晚上做了性生活的梦，结果也是肚子疼了20分钟，当时医生怕是宫外孕或先兆流产，结果让我住院保胎，虽然打了HCG和孕酮的针，但是那个值一直在降，B超宫内宫外都看不到孕囊，后来1月7日（大概是52天的时候）见红就自然流产了，没有做清宫，因为医生说流干净了，不需要做清宫，我这次和上次间隔时间是不是很短呢？

The 52 cases (57.78%)were with type of uterine tube clumps, and the feature of acoustic image showed clump echo were irregularity boundary, internal echo were uneven, gestational sac were not clear and there were a little or a few of fluidify when tubal pregnancys were ruptured.

输卵管妊囊型27例(30.00%)，表现为较完整胎囊强回声光环，部分见胚芽；输卵管包块型52例(57.78%)，表现为边界不规则的包块回声，内部回声不均匀，胎囊显示不清楚；输卵管妊娠破裂出血时盆腔可见少或中量积液等。

The changes mentioned above make the hard membranous sac, the nerve root, the vertebral artery and the gangliated nerve stressed and stimulated, which produces a series of clinical symptom and form the cervical spondyolsis; On diagnosis, the CT is superior to the plain film of X-ray, but the latter is still the foundation and the preference.

由于上述改变致硬膜囊，神经根、椎动脉受压及交感受神经受压、刺激产生一系列的临床症状，形成颈椎病；CT在其诊断上虽较X线平片优越，但平片仍是基础和首选。

But no worries, by the time we goback to school to do our sac,MrWood would definitely give us more.

All the patients were treated by high ligation of the hernial sac around the inner ring under laparoscope.

目的：评价自制缝合针在小儿腹股沟斜疝腹腔镜治疗中的疗效及并发症。

Methods:The data of sixty patients with indirect inguinal hernia underwent laparoscopic high ligation of hernial sac using selfmade instrument were analyzed retrospectively.

Aiming at the currently shortage of XML streams quality detecting, this paper proposes a new forecasting method of XML streams quality by least squares support vector machines, which is used the method of XML keys' vector matrix as windows, and vector product wavelet transform to multilevel decompose and refactor the XML streams series, that can fulfill real-time checking demand of XML quality, and ensure constraint, consist- ency and integrality. For even more adapting net load, it proposes a control strategy by weight and adaptive adjustment to ensure XML streams quality.

针对当前XML数据流质量检测存在的不足，提出构建XML键的矢量矩阵作为窗口，利用矢量积小波变换多级分解与重构XML数据流，再结合最小二乘支持向量机对XML数据流质量进行预测的一种方法，满足XML数据流质量重构时实时检测的要求，保证XML数据的约束性、一致性与完整性；为了更好的适应网络负载，采取加权与自适应窗口调整等调度策略充分保证XML数据流的质量检测。
