【Cell Reports:在COVID-19中早期功能性SARS-CoV-2特异性T细胞应答可预防严重感染】抗体和T细胞是人体免疫系统的组成部分，它们可以直接对抗病毒感染并清除被感染的细胞。最近，一项由杜克-新加坡国立大学医学院的科学家发表的新研究提供证据表明，COVID-19中早期出现SARS-CoV-2-特异性T细胞或能预防严重病症。相关研究结果于2021年1月21日发表在Cell Reports期刊上，标题为Early induction of functional SARS-CoV-2-specific T cells associates with rapid viral clearance and mild disease in COVID-19 patients。该研究对COVID-19患者的临床管理具有重要意义。https://t.cn/A65Ei6V1

下午的阳光总是那么的多愁善感
情绪不经意间从杯口香气中溢散

情绪片或者胶片风格那么浓郁又内敛

倚在角落
点一杯咖啡
摊开一本书
让阳光肆意在指尖跳舞

⭐️地点：大华1935 星巴克
⭐️出镜：大黄小仙女
⭐️：小李

⭐️拍摄过程：很喜欢ins上韩国摄影师mild.moon的照片，所以一直想模仿。借着午后阳光，约了朋友在星巴克拍了这组照片，情绪片拍摄要多尝试不同的角度，姿势。妆造也十分关键，好的妆造更好的将情绪宣泄出来。像这件白色衬衫就把气质立马展现出来，这种温柔的气质是亚洲人独有的，然后用胶片风格将这种气质酝酿出来。

⭐️和好看的仙女拍照就是一种享受啊！
快来和小李一起拍照吧！

Ultra marathon runner reveals horrific sunburn she caught on 69-mile run that caused massive blisters to form under the skin.

Sunburn is an inflammatory reaction to ultraviolet (UV) radiation damage to the skin’s outermost layers. At the heart of it all is melanin, a pigment that gives your skin its color and defends it against the sun’s rays. Melanin works by darkening your unprotected sun-exposed skin. The amount of melanin you produce is determined by genetics, which is why some people get sunburned while others tan. Both are signs of cellular damage to the skin. For people with less melanin, prolonged unprotected sun exposure can cause skin cells to become red, swollen and painful, also known as sunburn. Sunburns can range from mild to blistering.
