Sci Transl Med:迷你设备可测量紫外线指数

2018-12-10 唐一尘 中国科学报

当需要捕捉一些光线时,很难找到合适的平衡点。日照时间过短会导致缺乏维生素D和睡眠紊乱,而过长则会造成严重晒伤,并增加患皮肤癌的风险。

当需要捕捉一些光线时,很难找到合适的平衡点。日照时间过短会导致缺乏维生素D和睡眠紊乱,而过长则会造成严重晒伤,并增加患皮肤癌的风险。

测紫外线照射量通常需要依靠放射量测定器,这类设备只有名牌或手表那么大,能通过光敏材料计算包括阳光在内的不同类型辐射的照射量。但它们通常很昂贵,供能的电池组对水损害敏感,而且必须用皮带或夹子固定在衣服上,这样就显得很笨重。

那来看一款迷你放射量测定器吧。这款看起来像纽扣的设备能直接粘在皮肤或衣服上(即便衣服是湿的)。它采用一种光电二极管,可将光转化为电能,不仅能测量暴露的阳光,还可以测量电力。装置上的微型天线可将测量数据无线传输到用户的智能手机上。

为了测试这项技术,研究人员让志愿者在4天时间里,在身体不同部位佩戴多个迷你设备,同时参加各种户外活动,如远足和游泳。志愿者还佩戴了一个更大的传统放射量测定器进行比较。

研究团队近日在《科学—转化医学》上报告称,微型放射量测定器的表现与体积更大的传统设备一样好。由于志愿者可以同时佩戴多个微型放射量测定器,因此可以同时追踪身体不同部位的紫外线照射量。研究人员表示,这种装置的用途不仅限于防晒,还可用于医疗,比如对黄疸早产儿的光照治疗进行监测。

Nature:为何我们的造血干细胞存在于骨髓中?免受紫外线伤害是关键!

在人类和其他哺乳动物中,产生所有血细胞的造血干细胞位于骨髓中。但在鱼类中,造血干细胞存在于肾脏中。在20世纪70年代后期,生物学家们首次意识到血液在身体的特定部位---造血干细胞壁龛(blood stem cell niche)---中产生。从那时起,他们就一直想知道为何不同的生物在不同的部位中执行这种功能。

J Am Acad Dermatol:性别和地域性紫外线指数之间的相互作用与黑色素瘤风险是否相关?

背景:黑色素瘤是一种由皮肤和其他器官黑素细胞产生的肿瘤,表现为色素性皮损在数月或数年中发生明显改变。临床症状包括出血、瘙痒、压痛、溃疡等,其恶性程度高,转移发生早,死亡率高。全球每年有数以万计的人罹患这种疾病,其发病率攀升的速度比所有其他类型的实体瘤都要快。尽管人们认为黑色素瘤通常是由于过多的太阳紫外线照射引起的。但日晒和黑色素瘤之间的关联并不像看起来那样简单。对不同年龄和性别的黑色素瘤患者而言,

Cell Stem Cell:揭示紫外线诱发皮肤癌的分子机制

近日,一项刊登在国际杂志Cell Stem Cell上的研究报告中,来自康奈尔大学兽医学院的研究人员通过研究发现,当黑色素干细胞积累足够数量的基因突变时,其就会转变成癌症起源的细胞;在正常情况下,来自太阳光的紫外线照射(UV)会激活黑色素细胞释放黑素,黑素是一种能够保护皮肤免于太阳光晒伤的色素;但如果黑色素干细胞中积累的基因突变超过一定阈值时,当被日照所激活时就会引发肿瘤产生并生长。

SCI TRANSL MED:皮肤本身竟也能产生“防晒霜”?

现在市面上的防晒霜,主要通过吸收或反射紫外线来起到防晒的作用。那为什么我们的皮肤细胞不能自己反射太阳光呢?在最近的一项研究中,Mujahid等人让这个大胆的假设成为了现实。他们通过一种局部的小分子,刺激皮肤细胞产生可以抵御紫外线的色素沉积,从而达到保护的作用。

Br J Dermatol:夏天过去了,你的防晒衣起到作用了吗?

背景:防晒衣的主要作用是阻隔太阳紫外线(UVR)的直接照射,作用和遮阳伞是一样的。防晒服装于2007年在美国首先开始流行,随后进入中国。开始大多应用于户外产品当中,普通服装中的应用还比较少,之后受到了众多女生的青睐。一般专业的防护服可以起到防紫外线、防辐射的保健作用,但价格昂贵,适合特殊人群使用。目前热销的一些低价防晒衣更多是商家的概念炒作和噱头,虽然看起来漂亮、有遮荫效果,但透气性很差,也完全没

医用紫外线严重灼伤皮肤1例

中波紫外线常用于治疗银屑病、白癜风、湿疹等皮肤顽症,如防护不当则可造成眼睛、皮肤的灼务。2013年6月笔者采用MEBT/MEBO治疗1例经紫外线照射治疗银屑病时发生全身大面积皮肤灼身的患者,疗效显著,现报道如下。
