Design, Setting, and Patients After exposure to an index patient whose fatal illness was characterized by fever and hemorrhage at a primary care hospital and regional tertiary care hospital's isolation ward, secondary cases with febrile illness who were suspected of being exposed were tested for antibodies against Anaplasma phagocytophilum and by polymerase chain reaction and DNA sequencing for A phagocytophilum DNA.

HGA1990年在美国被创造，在欧洲被创造的时间则是在1997年。据报道，每年该疾病的感染人数在持续增加。有关数据显示，该种疾病在风行地区的感染率高达15%至36%，这意味着对该种疾病的诊断由于感染程度稍微或者是患者没有症状经常被遗漏。

2006年11月9日与17日之间在中国安徽省的一家地区医院中，为数9人的具有发烧和其它症状的病人被诊断患有HGA。这些病人都没有被蜱叮咬过。但所有这9位病人都在指标病例死亡前12小时内与其有过接触，该指标病例被怀疑患有致命性HGA，她出现了大出血并接受了气管内插管（即将一根柔韧的塑胶管子置放在气管中以帮助肺部的通气。）。

80 Individuals of ATA-A F2 plants were used for RAPD molecular mapping of the monoecious gene by bulk segregant analysis. 840 random primers were chosen for polymerase chain reaction amplification between monoecious pool and andromonoecious pool, the results showed that: primer S128 was tightly linked to the monoecious character, and primer S493 was tightly linked to the andromonoecious character.

以甜瓜单性花系ATA-A系与两性花品种YJX-1的杂交F2代的80个单株为材料，利用群分法进行单性花基因有关RAPD分子标记研究，筛选分析了840个10bp随机引物的PCR扩增谱带，结果表明，随机引物S128在1180bp，S493在930bp处产生与性别相关的特异性条带，S128的特异条带与单性花性状相关，S493的特异条带与两性花性状相关。

A personal interview was done and material for anogenital HPV DNA detection was obtained with swabs. HPV DNA was detected by polymerase chain reaction.

结果：600例研究对象的HPV DNA总阳性率为14.50%（87/600），其中性病患者HPV阳性率［23.90%（38／159）］显著高于非STD就诊者［11.11%（49／441）］（P0.05）。

In the present study, differential display polymerase chain reaction was used to isolate three antennal -specific mRNA from the moth of cotton bollworm. Sequence analysis indicated that A4-1 clone was homologous to the glutathione S-transferase family of proteins.

利用差异显示PCR的方法分离得到了3条棉铃虫触角专一性的mRNA片段，在GenBank中进行同源搜索表明，克隆A4-1与昆虫谷胱甘肽-S-转移酶基因家族具有很高的同源性。

THE Suharto regime used to argue that if East Timor became independent, it would set off an archipelagic chain reaction.

苏哈托政府过去反复声称如果东帝汶独立，它将导致列岛的连锁反应。

THE Suharto regime used to argue that if East Timor became independent, it would set off an archipelagic chain reaction.

苏哈托政权曾经放言假如有一天东渧汶闹独立，这也就等于拉响了群岛的连续阻击战。

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％。
