[@alzoron]

Another thing not mentioned in the video that makes prions scary is that they're notoriously difficult to destroy. They can survive radiation, disinfectants and high temperature. Basically everything we normally do to disinfect food and food preparation surfaces does nothing to prions.

[@masterkevkev]

That's basically because prions aren't actually "Bacteria" or a virus... they're just proteins. Bad.... bad proteins.

[@VienerSchnitzel69]

And they have a 100% mortality rate meaning that they are the only infectiously spread disease that kills everyone it infects.

[@beezusHrist]

[@kimboxdorfer7010]

I have unfortunately been learning about prion disease for the last 15 years. My family carries the genetic mutation for CJD (sometimes called fCJD because it's familial). If you have this genetic mutation your life proceeds as normal from birth and then something kickstart's the disease. My grandma was in her sixties, my mom was in her late 50s, and I had a cousin pass this summer in her early forties. Once you begin having symptoms there's nothing to do, no treatment, no help. You have weeks to months to live at that point. And every part of you that makes you, disappears. You start feeling dizzy and maybe have a slight hand tremor. The neurologist tells you you're crazy to think that it's cjd. Don't you know how rare it is? They've never had a single patient with cjd! It's much more likely an essential tremor. You have trouble remembering words, being able to speak your thoughts clearly. You lose the ability to walk and dementia starts. Pain comes when you're no longer able to move limbs like you could before and all your muscles lock up. And of course bladder and bowel control also goes pretty quickly. Towards the end you lose consciousness, only really waking when your body is turned to prevent bed sores or your catheter is checked and that's because of pain. And then when you're lucky you stop breathing. If you carry the mutation for this disease, you will develop it at some point. And you have a 50% chance of passing this autosomally dominant mutation to your children. And you have to watch family member after family member go through the same thing. And the neurologist who didn't believe you before now sends you Christmas cards, every year. Because the thing you hate most about your family, he finds interesting. And there is a stigma. Funeral homes don't really want your body. They suggest direct to cremation or a closed casket with no embalming. No one in your family, even those who test negative, can ever donate blood again or an organ. But of course you don't want anyone else to ever have to have this disease(not that they could get it from someone who tested negative), so why would you argue. And there's also this idea that you have something in your body that is both genetic and contagious. I used to tell the people at my work that if I fell and cracked my head open to just leave me be. All because of a tiny misfolding Prion...

[@kimboxdorfer7010]

@@moshariff6320 Life finds a way to continue. The realization that everybody dies actually brings comfort. Mostly because it means that you aren't that special, even with a rare genetic disease in your family. The trauma does continue. We all had young families when we learned about fCJD and now those babies are on the cusp of adulthood. There is an invisible divide in our family, because we know the genetic status of the children of the family members who tested negative. You can't pass on an autosomal dominant mutation if you don't have it. Those kids and young adults are safe. But the children of family members who carry the mutation will need to have hard conversations. We've never hidden this, but we have also never sat down and explained it in detail. They will need to decide if they want to be tested, if they want to have children, if they want to participate in research. They will have to figure out for themselves how to live with this. So as a family we are celebrating 16th birthdays, first loves, and high school graduations with this hanging over our heads. But life continues and for the most part, I am doing OK. Thanks for asking.

Colera and Polio are still there and the news don't talk about tuberculosis as much as they should given that it is one of the most common infectious diseases in the world. BTW, there was a case of vCJD last year.

[@PopsicleSponge]

I studied this at uni and wrote a paper about it. Its a prion disease. The protein chains affected adopt a different tertiary folding structure. One in which the atoms actually take up less space than in the original thus leading to gaps and an overall spongey bulk material. Because this incorrect form is actually more energetically favorable it acts as a template or chaperone protein. nearby proteins of the same secondary polypeptide chain structure, naturally follow the influence of this new form and follow suit to adopt that same folded shape.The entropy of this interaction is wholly -ve meaning no effort is actually required to keep it going once its begun, so the change is spontaneous once infection occurs. Some of the first investigations into CJD were on a disease called Kuru. Tribes in papa new guinea had a tradition of eating the brain tissue of dead tribe members after their passing, but without cooking it. This lead to the incorrect, for our bodies needs anyway, but again energetically favorable structure getting into the body. Leading to degeneration. And killing alot of people. And BSE turned my dad vegetarian for about 15 years xD. Please Fact check me on this. I'm sure someone can spot an error here.

It'd be good to mention the name of the protein, prion protein (PrP), as well as its extremely heavy concentration in the brain relative to the rest of the body. I also have to ask, your father had Classic CJD rather than vCJD correct.

it's not the cannibalism that is the issue. prion diseases are caused by consuming infected nervous tissue (brains/spinal cords). it can and does cross species. the mad cow outbreak was due largely to feeding infected sheep to cows. humans can get it from eating infected squirrel brains.

There is a similar prion disease in humans called Kuru. Groups in Papua New Guinea that practiced cannibalism in funeral ceremonies cooked and ate most of the body including the brain. After the practice was discontinued new cases dropped dramatically but it still popped up for over 50 years from people who were infected before the practice was ended. The last official death from Kuru was in 2009 and the epidemic was declared over in 2012 with no verifiable cases since.

[@TheBespectacledN00b]

The practice started in the 1950s if I remember rightly. The British government in this segment days had a mania for improved self sufficiency in food, given the German U-boats had nearly starved us out during the Second World War. So encouragement was given to anything that could get meat production moving more quickly was to be welcomed. For context, meat was still rationed in the early fifties in Britain. And people were getting pretty sick of it.

Irrelevant question but how was the move from the UK to the US?

[@Ayverie4]

Duncan Ellis My husband was born in the UK and only lived there until like 6 months old. Maybe never even ate any food yet. But he still can't give blood.

[@SuperStarwarsfan101]

I once knew a girl in high school who also was from the U.S. and moved to the U.K. around the late 90s or early 00s and she also can't give blood, because she may have the disease.

This video made me one step closer to going vegan

[@lsr64]

Cosas Caseras you should, its better for the environments.

[@octapusxft]

But what about the plant lives?

[@lite0221]

Take a step back away from it. They're lunatics I tell you.

[@VictorXimenes]

Nobody cares. You won't be changing the world for the better if you do it, it will be just a indivudualist choice that will make you feel better at night.

[@Grahf0]

3:33 the bit about donating blood. It seems every blood drive I run into, I seem to be the first one to have ever educated any of the people taking blood on this. When I tell them I cannot donate blood because I lived in Germany between 1978 and 1982, and again between 1988 and 1994, they just look at me like I'm weird.

[@EarlSquirrelsonn]

I remember it in primary school in Ireland. We had to stand on mats with disinfectant before we went into the classrooms and everything.

[@MusiCaninesTheMusicalDogs]

So prions are proteins that can replicate by itself? Isn't this what DNA does? Couldn't prions the first perpetrators of life?

[@MusiCaninesTheMusicalDogs]

Doug sillig Thank you for taking your time to clarify my doubt.

[@runethief3041]

Doug sillig question how exactly do they modify others ? do they do the action of changing normal ones or do the normal ones transform to be like them ?

[@xFirebird925x]

As I understand it, proteins are just strands of amino acids folded in various ways (think various beads on a wire, with wire folded in different shapes). The shape of the protein can decide what it does. For example, a tube shaped protein can lodge itself in the outer layer of a cell and transport stuff in and out. Prion proteins are proteins folded in a "bad" way that causes other proteins of its same kind around it to also change their folded structure from the "good" one to the "bad" one, then they attach to each other and start to clump up. Eventually, they clump up into huge protein structures called amyloids, which then starts forming plaques in the nervous tissues. This leads to the "holes in the brain" thing, and starts causing all kinds of problems until the organism dies. Parkinson's disease, Huntington's disease, Alzheimer's disease, and amyotropic lateral sclerosis all happen about the same way.

I remember this during the 90's, I was too scared to go to McDonald's

[@wilfriedschuler3796]

@Sorzin If you really want to know more about "The Macdonalds" check in youtube the old ballade from Scotland "The massacre of Glencoe, by the corries" Here the soup Campbells are massacring the Mc Donalds. Deserves them right.

[@Tara........]

I ate beef in the U.K. during the 90's. CJD has always been there at the back of my mind because it can take decades for the symptoms to appear. It's not something that keeps me up at night but every once in a while I can't help thinking about the possibility.

[@MrBomasBalloons]

Prion disease may not be so uncommon. Deer have a prion disease (wasting disease), and so do mink. There's another human prion disease - Kuru. And recent research even suggests Alzheimer's may involve 2 prions.

[@lowlyworm9323]

Only 90s kids remember

[@watermelonineasterhay]

I don't fortunately, as I'm not an older 90s kid (born 89)

[@MalcolmCooks]

they made it illegal to grind up dead cows and feed them to living cows

[@normalhuman9878]

My mom lived in Germany in the 90’s and she’s not allowed to donate blood

[@DatTrueTruth]

my grandmother actually passed away in 2016 from mad cow disease. i don't think it's as rare as this video makes it out to be. No one knows how she got it but like the video says it can take years to actually show symptoms. Her doctor said it could be from a botox injection she had or from some steak she had eaten in Mexico.. however my aunt has known 2 people that have passed in the last 3 years from it. which leads me to believe it's likely more common than we want it to be. still incredibly rare but not that rare.

[@Novadolls]

Ha, seeing this is a blast from the past, because Mad Cow Disease was a special interest of mine a few years back.

[@itsSebastianl0lz]

Here I am thinking cows go mad, when they eat tomacco My life is a lie

[@gordonlawrence4749]

My first wife didn't need to worry about this - she was a mad cow already.

[@greysautumn398]

Just another reason to limit your meat consumption and lean to toward a veg diet. I see all the comments of people complaining about cows being fed to cows, but that wouldn't have happened without the INSANE demand for meat across industrialized nations. Think globally, act locally.

[@5hawks]

Speaking of insane, nobody in their right mind would feed meat to an herbivore except greedy humans.

[@Thebestusername-fy5sl]

What food contains all the ingredients that a cow needs to grow more meat cells? Cow meat. A cow can't digest a steak well, but if it's already powdered there's no problem. Aside from transmitting disease.

[@TheBespectacledN00b]

lamewarrior Not so much greed as "Britian is fed up of meat rationing me the war has been over for years, and btw we probably shouldn't rely on imports so much in case we can't protect our convoys in the next war".

[@MrItsaplane]

+lamewarrior Yeah and herbivores themselves who have been documented eating meat and other animal parts...

[@grantlahti4405]

you... vegan

[@DrSnegg]

When I was younger I thought Mad Cow Disease was like a Zombie infection and it scared me so much.

[@jasonwebb1882]

OMG, the early 90's???? I know I'm getting old but wow. I remember this happening and I remember not being able to find ground beef or steaks for like 6 months. They pulled all the meat out of the store when it was confirmed that a cow died of Mad Cow disease in the United States. If I remember correctly I think it was up in Seattle Washington. But whats tripping me out, it seems like it happened a lot sooner then the early 90's. I thought it was like 2000's. But to be honest I have not even thought about this in years. I'm glad that they got it under control, cause I love me some big thick Ribeyes. And also I remember them saying it was caused by them mixing cow crap in with their food. Just like pigs and how they get them to be so fat. They would have a 3 rack system. The top rack would get fed real food and the middle rack would only get half of what the top rack had. The bottom rack of pigs would be the fattest and the only thing that they ate was the poop from the top 2 racks. People are very mean and only care about one thing!! Money!!!! They don't care about how they treat these animals cause they are going to be slaughtered. I'm not a person that goes around and to fight animal rights like Peta. Peta goes overboard way to many times for me. When they called and told our president to not kill a fly with his hands and that there are more humain ways of doing it. That's was a joke in my eyes and a waste of the presidents time. President Obama was doing an interview on live TV and a fly had been bugging them. It landed on his pants and Obama slapped it and killing it. Then says ' Got the sucker '. It was awesome. Anyway I love animals and believe that what comes around goes around. You want to feed an animal that can't leave crap, well I hope that one day those people have to eat crap. Alsace out peeps.

[@RedstoneMaster78]

Holy cow!

[@eSKAone-]

You really belief the patties at your local burger place are pure ground beef? They grind all sorts of slaughter waste in there, including brains and other parts of the nervous systems

[@Resseti82939]

eSKAone they are now

[@eSKAone-]

SenpaiGaming Whatever let's you sleep at night ;)

[@Andreas918]

senpai is actually mostly correct. Ground meat lacks organ meat mainly because adding it would drastically change the flavor, texture, and feel of the meat. Ground meat is mostly made up of water, assorted plant mater for filling, and trimmings from chuck, sirloin, and round steaks. And in a study in 2008 that went through the ground beef of 8 different fast food chains, small traces of peripheral nerve tissue was found, but brain matter was no where to be seen.

[@TheBespectacledN00b]

Not brains, not in the UK anymore. Not if they want to be able to export to the EU. British beef sorts got banned for a number of years over BSE.

[@MrItsaplane]

+eSKAone Yeah no, that's not how it flies, beef comes from shoulder and back meat, I can tell you having eaten quite a few animals if others part were haphazardly thrown in you would know.

[@thedrunkenpilot]

I have a friend who drives a Prion, he's pretty douchey about it.

[@8jakeP8]

I wonder if autophagy through fasting could breakdown the prions as it does with other broken cells.

[@kilowhiskyforge5713]

Hey bro, I ain't seen you I this channel before but I dig how well you perform in front of a camera. Really well done. I would recommend practising your hand movement on camera. Try to include a bit more time bringing your hands together- clasping?- and then opening them up again during the key points and I believe that will make for a well rounded educational video. Cheers bro

[@napoleonfool]

"After cows die of BSE,they were ground up and fed to healthy cows..." So, they really use(d?!) cow meat to feed cows?

[@johnjacob688]

It's so weird, I was just talking to someone about this yesterday. We had a guy at work die from mad cow a while back at that's what sparked the conversation.

[@stormtempterf8058]

First rule of cannibalism: never eat the brains. You will literally rot your own XD. I liked that prion disease was used in The Book of Eli to indicate who had gone down that particular rabbit hole, with the town mechanic demanding a muscle steadiness test from Eli before letting him shop, and the elderly couple that seemed like they had parkinson's, but really they just had toooooo many brains, lol.

[@francoislacombe9071]

I never understood how prions could be transmitted through food. We cook our food, and also animal feed, which denatures proteins. Proteins are digested, which breaks them apart. Undigested proteins are not absorbed by the intestines. And finally, the few such proteins that could make it into the blood stream would have to get through the brain blood barrier to reach the brain itself. That's quite a gauntlet for those prions have to run and I'm amazed that any can manage to go through all of it.

[@Thebestusername-fy5sl]

The protein chains affected adopt a different tertiary folding structure. One in which the atoms actually take up less space than in the original thus leading to gaps and an overall spongey bulk material. Because this incorrect form is actually more energetically favorable it acts as a template or chaperone protein. nearby proteins of the same secondary polypeptide chain structure, naturally follow the influence of this new form and follow suit to adopt that same folded shape.The entropy of this interaction is wholly -ve meaning no effort is actually required to keep it going once its begun, so the change is spontaneous once infection occurs. Some of the first investigations into CJD were on a disease called Kuru. Tribes in papa new guinea had a tradition of eating the brain tissue of dead tribe members after their passing, but without cooking it. This lead to the incorrect, for our bodies needs anyway, but again energetically favorable structure getting into the body. Leading to degeneration. And killing alot of people.

[@gracewillis577]

Oh look its Inabber ! Hiiii

[@lizslilcorneroftheinstitution]

While I’d heard of BSE aka Mad Cow before, I only recently learned of vCJD and different aspects. I have no issue being upfront that when politics enters a scientific situation, generally very little good comes out of it. What I was horrified to learn was the extent to which ‘mechanically rendered meat’ products were served up to schools, military, and even programs like ‘Meals on wheels’. Obviously these products were a cheaper staple. Listening to surviving family members of those who died from this disease is horrifying enough but it sent me to level rage to hear ‘medical professionals’ intimidating the families to get them to stay silent to avoid panic. To look at a grieving parent and tell them they ‘need to stay silent, the media will make your life hell especially since you’re partially to blame for buying cheap meat’ should earn any professional a first class ticket to hell. But the story doesn’t end there. You have people who donated blood during this time frame. You have people who, because they knew someone who died of vCJD they were denied medical procedures and surgeries because there’s no way to sterilize the medical equipment. But scariest still is I’ve not heard any true, scientific based evidence that can tell someone the products, medications and vaccinations that use bovine based ingredients weren’t tainted. How can Science sit here and tell anyone those vaccines or gelatin coated pills were free of these prions? Especially in a condition that can have incubation periods that stretch across decades?!
