This reminds me of the scene in The Abyss where the rat is forced to breathe in oxygen-rich perfluorocarbons[1]. I think this idea of introducing oxygen through perfluorocarbons has been explored but not sure it’s made much headway in humans to date [2]. This paper seems like a clever idea to introduce the liquid anally where oxygen can diffuse through the linings, and to also use same liquid (because of its viscosit…

That mucus usually supports digestion of food, AFAIK?

Are you suggesting an IV-drip with likkidfood instead?

You better not know what else scientists do to rats. And please, don't even start on the argument that they do it for science and not for entertainment. Entertainment in the form of science fiction is crucial for inspiring new generations of scientists.

Scientists don't abuse or cause distress or panic in animals, just FYI. There are very strict rules around it.

Why do I have to think of the Apes, Dogs, and cats with a plug in their skull, for neuroscience? What about the countless bunnies and dogs, used for 'dermatologically tested' label for cosmetics, wet wipes, whatever, by rubbing that stuff in their eyes?

One strict ruler up yours!

Heart is truely an amazing organ - don't think we will get close to a mechanical replacement. Has multiple chambers, Has chambers that pump sequentially with different pressures and volumes, Never needs to stop for additional lubrication, Never needs to be "charged", Never stops for maintenance, Is powered by oxygen delivered by the red blood cells it is pumping, Is controlled by the body's "proprietary" electro-chem…

I don't care how amazing the body is (it is), blood flow needs constant flow with a pulse. Put two bellows in parallel, use a linear motor to push out quickly and pull in slowly on each, and voilà mechanical heart without shear. MIT licensed, go save lives you f'ers.

In a suitcase ???.

dumb question -- is it not possible to just directly oxygenate blood? like what stops having a special IV that takes blood out, oxygenates it, and puts it back in?

I'm not advocating it, but intravenous ozone is a treatment offered by some alternative medical practitioners, as is rectal ozone.

Could be used for anal bleaching as well, I guess.

Why would you even waste your time looking into it? Of course it's animal abuse.

I mean those rats thought they were being submerged in water. They know they can't breathe in water. They were freaking out.

Makes me wonder if they'd freak out less if they were unconscious while submerged.

I wonder what effects emerge from chronically removing intestinal mucosa

I've done it. Inflammation, sensitivity to bacterium, gut pain. The mucus regenerates but takes some time. I found that in my case diet cranberry juice and mastic gum helped until the mucus regenerated. Some people with severe IBS get to experience this often. I am thankful to not be one of them.

That sounds horrible

Anybody else concerned about the ethics of scrubbing intestines, injecting gas into intestines, then suffocation the mammals to death? Are animals in these procedures routinely anaesthetised?

It would be funny, if it wasn't dramatic, that animal cruelty is so common that people are only triggered by these exotic and very small scale experiments. Killing a few mice or cloning a few sheep is barbaric but slaughtering millions of mammals every single day is business as usual. Obviously as soon as one points that out the cognitive dissonance kicks in and the downvote brigade shows up

You have my upvote.
