New Study Reveals We Have One Thing to Thank Gonorrhea For_我的网站
一 | Researchers from the University of California's San Diego School of Medicine have found that gonorrhea, as unpleasant as it is, might be the reason that our grandparents even exist.,Humans are among the few species that continue to live after menopause, which might be because of the evolution-proven support that older women provide when it comes to raising children.,The new findings suggest that pressure from pathogens like gonorrhea developed human gene mutations that protected elderly people from cognitive decline and made sure they could live longer.,The discovery comes by comparing human and chimpanzee genomes. The comparison revealed that humans have their own unique version of the gene for CD33, a receptor in immune cells that plays an important role in binding to a type of sugar called sialic acid. Human cells are coated with it and it helps immune cells "recognize" other cells and not attack them.,"Somewhere along the evolutionary line, humans picked up an additional mutated form of CD33 that is missing the sugar-binding site," the authors said. "The mutated receptor no longer reacts to sialic acids on damaged cells and plaques, allowing the microglia to break them down. Indeed, higher levels of this CD33 variant were independently found to be protective against late-onset Alzheimer's.",It would seem that CD33 was selected by evolution for its survival advantages, later making sure that humans were able to have big families that represent several generations. All of this, albeit indirectly, thanks to gonorrhea.。 AI摘要 台商王任生返乡创业三十余载，丹尼斯集团计划未来五年再投105亿元于河南五市，布局八大消费场景，推动企业从零售向生活方式运营转型。 郑州8月22日电（记者 李文哲）刚刚立秋的洛阳，暑气尚未散尽，晚风里仍有一丝溽热。年逾九旬的王任生身着白色衬衣、深色西装外套，目光炯炯。这位老一辈台商回到故乡河南创业30余年，至今仍奔走在商业一线。 “洛阳是我的根，丹尼斯是这片土地上长出来的企业。”他缓步走上舞台，望着台下70余家品牌代表说。
二 | 1997年，祖籍河南洛阳的王任生从台湾回到故乡，在郑州人民路商圈开了第一家丹尼斯百货，一度创造“36个小时不打烊，单日营业额3.6亿元”的纪录。 20世纪90年代，中原消费市场正处于从计划经济向市场经济转型的过程中。省会郑州这座“火车拉来的城市”，人口集聚效应显现，商业环境逐步开放，台资企业迎来进入大陆市场的历史契机。 “有了河南经济发展，才有了丹尼斯的成就。
三 | ”王任生常把这句话挂在嘴边。在他看来，企业30余年的成长，深深嵌入了中原大地的发展脉络。
四 | 2025年，河南全省地区生产总值和社会消费品零售总额分别达到6.66万亿元、2.9万亿元，均同比增长5.6%，为丹尼斯加大投资提供了稳定的市场预期。 适逢国家“十五五”规划开局之年，丹尼斯集团近期发布未来五年发展规划，计划投资105亿元再投河南五座城市。 2015年，总投资20亿元的郑州丹尼斯大卫城开业，定位高端精品百货，2024年销售额达到107亿元，成为河南首家“百亿商场”。大卫城总经理常瑞程介绍，得益于河南的区位优势与市场潜力，大卫城汇聚起200余家品牌各类首店，成为高端潮奢商业地标，并形成跨区域客流，实现“一店带一片”的连带效应。 8月，洛阳九州里街区品牌启幕。这个占地45亩、总建筑面积7.6万平方米、总投资7亿元的沉浸式互动街区，商业运营时段将从传统10时至22时拉长至次日凌晨，通过音乐潮玩、社交餐饮、非遗文创等业态，构建全时段消费场景。 “政策给足了，产业承接力要跟得上。”丹尼斯百货事业处总经理薄涛表示，省市两级密集出台存量商业盘活、消费提质系列政策，洛阳入选消费新业态、新模式、新场景试点城市，为像九州里这样的非标商业项目提供了重要发展窗口。 根据丹尼斯集团公布的投资计划，105亿元投资将在未来五年内逐步落地，围绕夜生活、户外街区、空中主题街区、主题市集、特色市集、艺术特展、亲子家庭、绿色生态等八大场景展开布局，推动企业从商品零售向生活方式运营转变。 从1997年的一家百货店，到如今拥有18家百货、70多家大卖场、500多家便利店，以及地产、物流、酒店、加工厂的综合零售集团……“丹尼斯是这片土地上长出来的企业”这句话，王任生说了30多年，也做了30多年。
