The homologues of ptp-1 and ptp-2 genes were found in some lepidopterous baculoviruses, but not in non-lepidopterous baculoviruses. ApNPV was one of the four baculoviruses contained both ptp-1 and ptp-2 genes.

只有部分鳞翅目杆状病毒编码ptp-1、ptp-2基因同源区，非鳞翅目杆状病毒不编码ptp-1、ptp-2基因同源区，而ApNPV为鳞翅目杆状病毒，同时编码ptp-1、ptp-2基因同源区。

Was simultaneously injected into cisterna magna at the second injection blood in the presence of subarachnoid blood. At 2 to 4 days, GFP was expressed in leptomeninges over the brain stem, cortex and cerebral arteries, smooth muscle cells of small vessels were occasionlly transduced. GFP was expressed in adventitia of spastic basilar artery on days 2 (day 5 after first injection blood) after injection 〓, but was undetectable by days 4, transgene was not expressed in medial or intimal layers. The prensence of subarachnoid blood can not prevent access of adenovirus to vessels and transgene expression.

注入腺病毒载体后2天（初次注血第5天）行荧光显微镜、免疫组织化学和RT-PCR检测，结果在颅内大血管如基底动脉的外膜可见外源基因的表达，而外源基因不能转移至血管中膜和内膜，4天时（初次注血第7天）基底动脉的外膜中外源基因表达消失；注入腺病毒载体后2～4天，外源基因可以有效转移至颅底软脑膜细胞，小血管外膜和平滑肌层也可见外源基因的表达，表明蛛网膜下腔内的血凝块不能阻止腺病毒载体介导外源基因转移至颅内血管。

It is also possible that there is something unique about Mexico, such as that those who died were infected with another virus which interacts lethally with the new one.

也可能有一些墨西哥的独特之处，如那些死于感染其他病毒的人，这些病毒和新病毒相互作用后是致命的。

It is also possible that there is something unique about Mexico, such as that those who died were infected with another virus which interacts lethally with the new one.

还有可能是墨西哥有些特别之处，比如死亡的患者是感染了另外一种病毒，病毒和新病毒产生致命的相互作用。

Avian leukosis virus subgroup J was first isolated in 1989 and identified as a new subgroup of avian leukosis virus.

J亚群禽白血病病毒是1989年被分离、鉴定出的一个新的禽白血病病毒亚群，与其它ALV亚群比较，该亚群病毒的一个显著特点是其env基因非常独特。

Most of the avian lymphomas are associated with Marek''s disease virus, avian leukosis virus or reticuloendotheliosis virus.

大部分的禽类淋巴瘤多与马立克病病毒（Marek's disease virus， MDV）家禽白血病病毒（Avian leukosis virus， ALV）及网状内皮细胞增生症病毒（Reticuloendotheliosis virus， REV）有关。

The virus to Lymantria dispar virus as an example, the production also reached a virus prevention and control is equivalent to the production capacity of 3 million mu, only in Beijing's Fangshan, Daxing districts on the cumulative use of 30,000 mu, of Lymantria dispar effect in 1995 Percent.

在病毒方面，以舞毒蛾病毒为例，也达到了年生产病毒折合防治面积3万亩的生产能力，仅在北京市房山、大兴两区就累计使用3万多亩，防治舞毒蛾效果在95％以上。

We identified the geminivirus in Malvastrum coromandelianum from the molecular level by designing the primers, PCR, cloning and sequencing.

从杂草赛葵上采集了2组病毒样本Fz1和Fs1，用双生病毒通用引物PA、PB对杂草样本进行特异性的PCR检测，结果发现：赛葵样本Fz1和Fs1都出现约500bp的条带，说明这些杂草赛葵上存在双生病毒。

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％。
