The.Multi Ye.r Tariff Orde. (MYTO) is the.Nige.ian e.e.tricity Re.ulatory Commission (Ne.C) pricing frame.ork for de.e.mining the.Nige.ian e.e.tricity Supply Industry (Ne.I) pricing mode.. One.of the.obje.tive. of the.Ne.C’s MYTO pricing mode. is to e.sure.re.ulate. e.e.tricity e.d use. tariff without compromising re.urn on inve.tme.t.

目的利用盆腔MR成像构建并初步验证MRI评分系统能为超声不能确诊的附件区肿物定性。材料与方法本项回顾性研究经机构伦理委员会批准,并免除知情同意书。本研究包括394例于2008年1月1日—2010年10月30日间行MR成像的女性病人,经超声确诊共497个附件区肿物。按照时间先后顺序将肿物分为训练组(329个)和验证组(168个)。2位放射科医师采用双盲法独立地评估MR影像表现以便对附件区肿物进行定性。参考手术后的病理结果或至少1年后的影像随访结果。计算训练组中每一种恶性肿瘤影像表现的阳性似然比(PLR)和κ值。基于PLR和多变量分析,创建一个名为ADNe. MR SCORING系统的5级MR评分系统,随后由6名医师对验证组进行测试。结果除瘤内多发的分隔(κ=0.558)和均匀增厚的分隔(κ=0.555)外,其他每个MR影像表现都具有良好的一致性(κ=0.08)。训练组[医师1的ROC曲线下面积(AUC)=0.981,医师2的AUC=0.943]与验证组(医师1的AUC=0.964,医师2的AUC=0.943)的分类都是准确的。ROC曲线分析表明ADNe. MR评分=3为最佳阈值;ADNe.MR评分≥4与恶性肿瘤有关,其敏感度和特异度分别为93.5%(58/62)和96.6%(258/267)。结论本研究开发并测试了一种可重复的、准确的并可改善病人治疗的MR成像评估系统,但仍需多中心、前瞻性研究对其加以验证。

The.antibiotic biosynthe.is monooxyge.ase.domain, an e.olutionarily ancie.t compone.t, is akin to atypical he.e.oxyge.ase. in prokaryote. but is not we.lcharacte.ize. in ve.te.rate..
