因为线粒体衰退牵涉到许多疾病,这样的发现可能有助于启发帕金森症和糖尿病等疾病的新疗法。
The study was small, a pilot study to test the concept. Researchers recruited 12 men and 12 women, whose ages ranged from 28 to 72. Each participant was given a small handheld flashlight that emitted a red light with a wavelength of 670 nanometers. That wavelength is toward the long end of the visible spectrum, and just short of an infrared wavelength, which tends to be invisible to the human eye.
这项研究是一个小型的试点项目,旨在测试这一概念。研究人员招募了12名男性和12名女性,他们的年龄在28岁到72岁之间。每位参与者都分到了一个手持的小手电筒,可以发出波长670纳米的红光。这种红光的波长接近可见光谱波长最长的一端,只有人眼通常看不见的红外线的波长才比它短。
They spent three minutes each day looking into the light over a period of two weeks.
在两周时间内,参与者每天花三分钟凝视红光。
The lights work on both cones and rods in the eye. Cones are photo receptor cells that detect color and work best in well-lit situations. Rods, which are much more plentiful, are retina cells that specialize in helping us see in dim light, according to the American Academy of Ophthalmology.
这种红光对眼睛的视锥细胞和视杆细胞都产生了作用。根据美国眼科学会,视锥细胞是可以察觉颜色的感光细胞,在光线明亮的情况下最能发挥作用。数量庞大得多的视杆细胞是视网膜细胞,主要功能是帮我们在光线昏暗时看见东西。
