Background: Evidence regarding the effectiveness of prenatal nutritional supplements has mainly considered anthropometric pregnancy outcomes. The effect on markers of health and disease， such as offspring telomere length (TL) and mitochondrial DNA content (mtDNAc) is unknown. Objectives: We assessed the efficacy of maternal multiple micronutrient (MMN)-fortified balanced-energy protein (BEP) and iron-folic acid (IFA) supplementation on newborn TL as a secondary outcome and mtDNAc as a non-declared outcome. design: We conducted a randomized controlled trial in rural Burkina Faso， among pregnant females (15-40 years old) enrolled at ks of gestation. Mothers received either MMN-fortified BEP and IFA (intervention) or IFA only (control) throughout pregnancy. Whole arterial blood samples were collected from the umbilical cord of 104 control and 90 intervention group infants， respectively. Average relative TL and mtDNAc were measured using quantitative polymerase chain reaction. Linear regression models were fitted to assess TL and mtDNAc differences across trial arms. Results: We found that a combined daily MMN-fortified BEP supplement and IFA tablet did not affect newborn TL [β = -0.010 (95% CI: -0.057， 0.036); P = 0.662] or mtDNAc [β = 0.065 (95% CI: -0.203， 0.073); P = 0.354]， as compared to an IFA tablet alone. These findings were confirmed (P > 0.05) by adjusting the regression models for potential prognostic factors of study outcomes at enrollment. Exploratory analyses indicated higher， but non-significantly different mtDNAc among children born either small-for-gestational age， low birthweight， or preterm. Conclusions: Newborns from mothers who received daily nutritional supplements across gestation did not have different relative TL or mtDNAc.

狄金森、徐志摩、赛珍珠不仅是万众瞩目的公共知识分子,还是重要的文学和政治团体的创始成员,是跨国文学共同体网络的一部分。他们与自己国家格格不入,却在异国他乡建构身份认同,都在自己的祖国和海外留下丰富的文化遗产,促进了中英之间和中美之间极具活力的文化交流。他们对本国的批评之所以令人信服,部分原因在于他们曾长时间生活在他者文化中,由此获得审视故土道德标准和国家政策所必要的批评距离。以对位视角来看,他们是早期移民作家和学者的杰出代表,他们相信多元交融的必要性,相信促进多元世界文化遗产,尤其是鼓励批评性文化以及民族自省的必要性。

A human's e-life needs multiple offline and online accounts. It is a balance between usability and security to set keys or passwords for these multiple accounts. Password reuse has to be avoided due to the domino effect of malicious administrators and crackers. However,human memorability constrains the number of keys. single sign-on server,key hashing,key strengthening and petname system are used in the prior arts to use only one key for multiple online accounts. The unique site keys are derived from the common master secret and specific domain name. These methods cannot be applied to offline accounts such as file encryption. We invent a new method and system applicable to offline and online accounts. It does not depend on HTTP server and domain name,but numeric 4-digit passcode,key hashing,key strengthening and hash truncation. Domain name is only needed to resist spoofing and phishing attacks of online accounts.
