新型口香糖或減少新冠傳播

Researchers at the University of Pennsylvania are working to create a special chewing gum that could help reduce the spread of COVID-19 by "trapping" the virus so a person can't transmit it to someone else.

賓夕法尼亞大學新冠病毒研究人員正在努力研制一種特殊口香糖，它可以通過"誘捕"新冠病毒阻止其感染他人，從而幫助抑制新冠疫情傳播。

Experts agree vaccinations are the best way to combat the COVID-19 pandemic, but it's also known vaccinated people can still transmit the virus.
專家們認為接種疫苗是抗擊新冠的最佳手段，但眾所周知，已經(jīng)接種疫苗的人仍能傳播病毒。

The researchers are hoping their chewing gum will give people a low-cost way to further prevent COVID-19 from spreading.
賓夕法尼亞大學研究人員希望他們研發(fā)的口香糖能成為進一步控制疫情傳播的低成本方法。

The gum contains plant-grown ACE2 proteins, which showed in laboratory studies to have the capability to neutralize the SARS-CoV-2 virus.
口香糖含有植物產(chǎn)生的血管緊張素轉(zhuǎn)換酶2(ACE2)蛋白，實驗室研究表明這種蛋白可以中和新冠病毒。

When researchers exposed saliva samples from COVID-19 patients to the modified chewing gum, they found the levels of viral RNA were "drastically reduced" to the point the virus was almost undetectable.
研究人員讓新冠患者的唾液樣本與ACE2蛋白口香糖接觸，發(fā)現(xiàn)病毒RNA的含量"急劇下降"到幾乎檢測不到的程度。

The research is still in its early stages, and the researchers are working on getting permission to conduct a clinical trial in humans to determine if the gum is safe and effective.
這項研究仍處于早期階段，研究人員正在爭取進行人體臨床試驗的許可，以確定這種口香糖是否安全有效。
