为解决埃及儿童非综合征性感音神经性耳聋（SNHL）的遗传病因学问题，埃及国家研究中心的Hala M. Zeidan团队开展了线粒体12S rRNA A1555G突变筛查研究。通过PCR-RFLP技术对30例患儿进行检测，发现仅1例（3.3%）携带该突变，提示其在埃及人群中的贡献有限。该研究为中东地区线粒体耳聋突变谱提供了新数据，对预防氨基糖苷类抗生素耳毒性具有临床警示意义。

The objectives of the present study were the subtyping of Campylobacter jejuni subsp. jejuni strains obtained from humans and different animal species using PCR-RFLP, and the detection, by means of ...

PCR-based techniques are methods that rely on the polymerase chain reaction (PCR) to amplify stretches of DNA by creating many identical or near-identical copies. For example, PCR amplification ...
