Socrates Quotes. Mushroom poisoning. To prevent mushroom poisoning, mushroom gatherers need to be very familiar with the mushrooms they intend to collect as well as with any similar-looking toxic species. In addition, edibility of mushrooms may depend on methods of preparation for cooking. Collectors also need to be well aware that edibility or toxicity of some species varies with geographic location. [citation needed] Folk traditions[edit] There are many folk traditions concerning the defining features of poisonous mushrooms.[1][2] However, there are no general identifiers for poisonous mushrooms (only guidelines to identify mushrooms themselves exist, if one knows what mushroom is toxic), and so such traditions are unreliable guides.
Use of folk traditions to try to identify edible mushrooms is a frequent cause of mushroom poisoning. Causes of mushroom poisoning[edit] Discovery of new species of fungi occurs at a very high rate, with an estimated value of 800 new species registered annually. Recently[when?] Death from laughter. Death from laughter refers to a rare instance of death, usually resulting from cardiac arrest or asphyxiation, caused by a fit of laughter.
Instances of death by laughter have been recorded from Ancient Greece to the modern day. Pathophysiology[edit] Death may result from several pathologies that deviate from benign laughter. Infarction of the pons and medulla oblongata in the brain may cause pathological laughter.[1] Historical deaths attributed to laughter[edit] Fictional deaths attributed to laughter[edit] See also[edit] References[edit] External links[edit] Snopes.com article. Prion. A prion ( A protein as an infectious agent stands in contrast to all other known infectious agents, like viruses, bacteria, fungi, or parasites—all of which must contain nucleic acids (either DNA, RNA, or both). All known prion diseases in mammals affect the structure of the brain or other neural tissue and all are currently untreatable and universally fatal.[4] While PrP is considered the only mammalian prion, prion-like domains have been found in a variety of other mammalian proteins.
Some of these proteins have been implicated in the ontogeny of age-related degenerative disorders such as amyotrophic lateral sclerosis (ALS), frontotemporal lobar degeneration with ubiquitin-positive inclusions (FTLD-U), Alzheimer's disease, and Huntington's disease.[5] This has given rise to the 'prion paradigm', where otherwise harmless proteins can be converted to a pathogenic form by a small number of misfolded, nucleating proteins.[6] Prion Protein (PrP)[edit] Discovery[edit] In 1982, Stanley B.
