Eggs early in complementary feeding increase choline pathway biomarkers and DHA: a randomized controlled trial in Ecuador
egg nutrition children choline betaine vitamin B-12 docosahexaenoic acid
2018/11/21
Background: Choline status has been associated with stunting among young children. Findings from this study showed that an egg intervention improved linear growth by a length-for-age z score of 0.63.

Background: The omega-3 (n–3) long-chain polyunsaturated fatty acid (LCPUFA) docosahexaenoic acid (DHA) has proven effective at reducing fat storage in animal studies. However, a systematic review of ...
投加FeSO4对序批式生物膜反应器中DHA、EPS和处理效果的影响
硫酸亚铁 化学协同除磷 脱氢酶活性 胞外聚合物
2016/8/15
针对化学协同生物除磷过程,研究了序批式生物膜反应器(SBBR)中FeSO4对悬浮相活性污泥脱氢酶活性(DHA)、胞外聚合物(EPS)及系统处理效果的影响.结果表明,少量FeSO4对DHA和EPS的分泌具有促进作用,但最佳投加量不一致,分别为0.10 mmol·L-1和0.20 mmol·L-1;大量的FeSO4则会引发抑制.FeSO4投加量少于0.30 mmol·L-1时会使污泥MLVSS、MLV...
对缩减轮数DHA-256的原像与伪碰撞攻击
DHA-256散列函数 原像攻击 伪碰撞攻击 中间相遇攻击
2014/3/21
提出了对DHA-256散列函数37轮的原像攻击以及39轮的伪碰撞攻击。基于中间相遇攻击,利用Biclique方法可以改进之前对DHA-256的原像分析结果,将攻击轮数从原来的35轮提高到了37轮。通过上述方法还可以构造对DHA-256的39轮伪碰撞。最终,以2255.5的时间复杂度以及23的空间复杂度构造了对DHA-256的37轮原像,并以2127.5的时间复杂度以及常数2的空间复杂度构造了对DH...
