托福阅读资料：拿什么拯救90后的发际线

托福阅读考试前考生需要积累大量的素材资料，现在信息传播越来越广泛，很多重要信息我们可能没有精力去接触，那么如果出现在自己的托福阅读考试中，大家能否快速的理解文章内容呢?以下是小编为大家整理的托福阅读资料：拿什么拯救90后的发际线，供大家学习。

Led by professor Choi Kang-yeol of Yonsei University, a team of researchers discovered a protein responsible for hair loss in androgenetic alopecia, also known as pattern baldness - the most common type of hair loss in both men and women.

由延世大学教授崔康烈(音译)带领的研究团队发现了一种导致雄激素源性脱发(又称斑秃)的蛋白质。雄激素源性脱发是男性和女性最常见的脱发类型。

崔康烈教授表示：

“We have found a protein that controls the hair growth and developed a new substance that promotes hair regeneration by controlling the function of the protein. We expect that the newly developed substance will contribute to the development of a drug that not only treats hair loss but also regenerate damaged skin tissues.”

“我们发现了一种可以控制头发生长的蛋白质，并研发了一种新物质，通过控制蛋白质的功能来促进毛发再生。我们认为，这种新研发的物质将有助于研制一种能够治疗脱发，且能促进受损皮肤组织再生的药物。”

科学家发现当一种叫做CXXC5的蛋白质与散乱蛋白结合时，它们会阻遏Wnt (一种复杂的蛋白质作用网络，与毛发再生和伤口愈合有关) 信号通路，从而影响毛囊生长及再生秩序。

A new biomaterial developed by the team interferes with this binding process. It's called PTD-DBM, and when applied to the bare skin of bald mice for 28 days, new follicles developed.

为了干扰这种结合过程，研究人员研制出一种名为PTD-PBD的生物材料，并将这种物质涂在无毛白鼠皮肤上，持续28天后，白鼠长出了新的毛囊。

而根据2007年的一项研究，在小鼠实验中，某些情况下，直径超过5毫米的伤口在愈合时会产生新的毛囊。

The strongest result that Kang-yeol's team saw was after combining wound-induced hair neogenesis with PTD-PBM and valproic acid, usually used to treat seizures, bipolar, schizophrenia and migraines. In this instance it was used topically to activate the Wnt/β-catenin pathway.

崔康烈的研究团队发现，将创伤诱发毛发再生，PTD-PBD和丙戊酸结合起来，取得的效果最明显。丙戊酸通常用于治疗癫痫、双向情感障碍、精神分裂和偏头痛，在这个实验里用来激活Wnt信号通路。

So there's a threefold action. The wounds induce the generation of follicles; the valproic acid stimulates the cell pathway linked to the development of follicles; and the PTD-PBD inhibits prevents CXXC5 from interfering with the follicular development process.

创伤诱发毛囊再生、丙戊酸刺激与毛囊生长有关的细胞通路、PTD-PBD抑制剂阻止CXXC5干扰毛囊生长的过程，这三者结合产生了三重作用。

New treatments often take time to develop, not least because they need to go through clinical trials to determine their safety - and, as we know, using mouse models to study how well things might respond in humans doesn't always work.

新的治疗方法通常需要很长一段研发时间，尤其是需要通过临床实验来确定其安全性。毕竟，以实验小鼠代替人类来研究反应效果并不总是奏效。

Nevertheless, the team's research is progressing apace. They're currently testing their new substance on animals to determine whether it's toxic, before proceeding to human trials.

不过，研究团队进展迅速。他们目前正在动物身上测试这种新物质，以确定是否有毒，然后再考虑进行人体试验。

如果这个方法真的可行，那简直就是秃头人士的福音啊!
