Citing infowars as a source is not better than citing some ultra-liberal political pundit source for the other side.
Is there a link to the video taken down by YouTube that is actually put out by Cedars-Sinai? The purported re-posting of the video on Aytu's website looks like a commercial video put out by a biotech company. Cedars-Sinai's website doesn't say a whole lot.
The only thing I can find from Cedars-Sinai is an article they submitted to a somewhat obscure European journal using the Heallight technology in colonoscopy to alter gut flora. From anatomical standpoint, bacterial flora standpoint, and even technical aspect standpoint, that's apples and oranges comparing to using it in the lungs.
If all Cedars-Sinai has done is it's use in colonoscopy as proof of concept, it is actually very, very far away from being a realistic option for COVID patients even if it actually works. We are talking about COVID 20, COVD 21 or beyond, and most likely never if it's based on endoscopic UVC technology.
In a colonoscopy, the scope has direct access to the entire mucosa in the colon, so the light does not need to go through human tissue to affect bacterial flora inside your colon.
In the lungs, the bronchoscope reaches a very, very, very small percentage of your actual bronchial tree (it gets too small for any instruments beyond the first few branches). So overwhelming majority of the bronchial tree is not accessible by bronchoscope, meaning overwhelming majority of lung tissues, including 100% of lower lung tissues where COVID does damage, is inaccessible to a bronchoscope. AND, UVC lights have very poor penetrance in living human tissues, so it's not going to go very far from inside the bronchial tree... it is very unlikely for UVC lights to get into the actual lung tissues where COVID is.
Interesting concept, but the application is more likely in the GI system and not the pulmonary system.
So where is the video? There are plenty of other platforms. The video was supposedly reposted by Aytu Bioscience, but the only video on their website is a commercial video that is nothing more than a bad infomercial with no sources identified. The ONLY source Aytu Bioscience identified is a Cedars-Sinai article about its use in colonoscopy in an obscure foreign journal.
And, Cedars-Sinai did not mention it being applicable in bronchoscopy, FDA has not approved it, and Aytu BioScience is being very vague on how this will work when any second year medical student with a year of gross anatomy under their belt knows that it doesn't make sense anatomically.
The most likely explanation is, Cedars-Sinai really has nothing to do with this other than having this technology they were hoping to explore for colonoscopy use, and Aytu is the biotechnical/manufacturing avenue for it. And Aytu just used COVID 19 as a free publicity tool while the actual intent is use for colonoscopy all along.
