These cases are sufficiently rave, I think, to merit report with a view to inviting the experiences of others in regard to them. Medical literature, so far as it is within my reach, or within the reach of medical friends, makes no reference to such phenomena.

متن کاملPrPC expression and prion seeding activity in the alimentary tract and lymphoid tissue of deer
The agent responsible for prion diseases is a misfolded form of a normal protein (PrPC). The prion hypothesis stipulates that PrPC must be present for the disease to manifest. Cervid populations across the world are infected with chronic wasting disease, a horizontally-transmissible prion disease that is likely spread via oral exposure to infectious prions (PrPCWD). Though PrPCWD has been ident...

متن کاملThe absorption of glucose from the alimentary canal.

It was also shown that the amount of glucose absorbed was related to crop emptying, so that the limiting process in absorption was not the transfer of glucose across the gut wall but the rate at which fluid was allowed to leave the crop....
