血色浪漫

A | 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.。 8 月 26 日消息，洛阳长江科技有限公司今日发布两款全新 ADV 风格边三轮摩托车 —— 长江 700X 与挎刀 250（KD250）。其中，长江 700X 官方指导价为 63,800 元；挎刀 250 提供标准版与特别版两种配置，售价分别为 29,800 元和 32,800 元。据官方介绍，长江 700X 采用现代 ADV 外观设计风格，融合了长江品牌经典的边三轮（俗称“侉子”）基因。动力方面搭载来自春风的 700cc 水冷并列双缸发动机，实际排量 693cc，最大功率 55 千瓦（注：约 74.7 马力）在 8500 转 / 分钟时爆发，峰值扭矩 68 牛 · 米在 6500 转 / 分钟时产生。变速箱提供 4 个前进挡和倒挡，标配滑动离合器，采用链条传动。
