Here are some links outlining the details mentioned, but I mostly use a combination of sources from books that ive read, to articles that Ive found interesting and ones that utilize good research methodologies. pubmed.ncbi.nlm.nih.gov/11373012/ www.scientificamerican.com/article/evidence-for-person-to-person-transmission-of-alzheimer-s-pathology/ academic.oup.com/jnen/article/78/11/993/5568265?login=true www.kevinmd.com/blog/2021/01/are-we-underestimating-the-danger-of-prions-and-prion-based-diseases.html Let me know what you think

Does a prions contains nucleic acid?

so can you only get prions from eating the brain only or no?

no, you can get infected with a prion from improper surgical technique ie poor sterilization.. hence why baby boomers all got hep C and alzheimers

So is there a concern with composting human bodies for use in the food cycle, such as Washington State just passed?
@medaphysicsrepository2639
@medaphysicsrepository2639 5 лет назад
okay, so after googling that: it seems they are burying humans in the ground with soil for plants and other fungi to grow and decompose the body. I generally understand this to be a very efficient process and would presume that even if a human being or animal for that matter had a prion, some fungi, protozoa or bacteria would have a protease to destroy it and use its amino acids for their own purposes: soil is a very ruthless environment for lifeforms. However, human remains (as well as animal remains) should be handled VERY strictly to prevent pathogen transmission. thanks for sharing, never knew about that

why chaperones do not refold the prions to their original native conformation....?
@medaphysicsrepository2639
@medaphysicsrepository2639 7 лет назад
VERY VERY GOOD QUESTION!!! your guess is as good as mine!, when I made this video I do remember looking into the pathophysiology of the protein folding itself and my understanding is that certain scientist hypothesized that chaperonins / heat shock proteins (same thing) actually assist the prions into folding into that configuration (it is very stable and thus thermodynamically favorable ) but not alot of physical evidence for this, especially in humans/mice. Id say that since prions are not very well defined and that they are at least somewhat involved in stabilizing memory formation it may be a normal pathway in the cells themselves that are screwed up, kind of analogous to parkinsons/alzheimers/ALS etc what do you think?

You are very smart to ask questions like that, it shows you have a good understanding of how cells work systematically
