AI Thread Summary
Recent research demonstrates that blood oxygenation can be achieved through the lower intestinal tract in both mice and pigs, potentially offering a new method for temporarily assisting human respiratory function. This enteral ventilation technique draws inspiration from loaches, which utilize intestinal air breathing. The study shows that intra-rectal delivery of a liquid oxygen compound, specifically conjugated perfluorocarbon, is both well-tolerated and effective in treating severe respiratory failure. This innovative approach may pave the way for new clinical applications in respiratory support.

Blood oxygenation through the lower intestinal tract is demonstrated in both mice and pigs. It is hoped this wiil work for those Humans that need temporary assistance with respiratory function.

Inspired by organisms such as loaches that use intestinal air breathing, we show the effectiveness of an enteral ventilation approach in attaining systemic oxygenation in both rodent and porcine models. Intra-rectal delivery of a liquid form of O2 known as conjugated perfluorocarbon, a compound historically used in clinics for liquid ventilation through airway administration, is highly tolerable and efficacious in ameliorating severe respiratory failure.

I've been reading a bunch of articles in this month's Scientific American on Alzheimer's and ran across this article in a web feed that I subscribe to. The SA articles that I've read so far have touched on issues with the blood-brain barrier but this appears to be a novel approach to the problem - fix the exit ramp and the brain clears out the plaques. https://www.sciencealert.com/new-alzheimers-treatment-clears-plaques-from-brains-of-mice-within-hours The original paper: Rapid amyloid-β...
