What he did was different though.  His team used their own blood for the transfusions.  IE Lance received Lance's Blood etc. I don't condone what he did at all.  But from what I read we are seeing people referenced to receiving Six Heart Transplants and many other things!

First thing that comes to mind, surprise surprise, is Dick Cheney.

Personally, I don't understand the kind of vanity that drives this movement.

Who the hell wants to live forever in this POS meatbag? Why would you abuse your body with plastic surgery to ward off the ravages of aging?

You're not fooling anyone. Now, not only are you old, you're twice as ugly and fake to boot.

Leslie Stahl makes my skin crawl. I already hate her lefty guts, but she's hideous to look at too. Michael Jackson? A very depressed man. Wildenstein? OMFGWTFIT?!

Kill it with fire!

Now we've got bloodsuckers trying to cheat aging and death.

Where does the absurdity end?

The root of violence? Mice become MEAN when they are injected with an antibody taken from the blood of human murderers, rapists and gang members

Quote
The puzzle of why some people turn to extreme violence may be a step closer to being solved, following the findings of a new study.
Norwegian scientists injected mice with an antibody sourced from the blood of murderers, rapists and gang members.
After being injected, they found that these rodents resorted to violent confrontations with their fellow creatures far more quickly than normal.
This suggests variations in the antibody found between people may be a factor in how aggressively they respond to stress.
The finding could one day lead to a treatment for violent criminals, although researchers warn this is still some way off.

9 Secrets Your Blood Type Reveals About You
Jessica Migala     59 minutes ago

Your blood type matters
Unless you've recently given blood, you may not think much about your blood type. The presence or absence of certain molecules called A or B antigens, as well as a protein called the Rh factor, determine which of the eight common blood types you have coursing through your veins. (Groups: A+, A-, B+, B-, AB+, AB-, O+ or O-.) However, these antigens make a difference beyond just your blood, influencing other body systems like your blood vessels, nerve cells, and blood platelets—which is why your blood type may impact your risk of certain diseases. Here's why you should know what blood type you have.

Type A, B, AB: Heart disease
Non-O blood types have 25 to 30 percent higher levels of blood clotting proteins known as von Willebrand factor and factor VIII. In part, because of that difference, these folks also have a 15 percent greater risk of dying from heart disease, reports 2015 research from BMC Medicine. Learn about the 9 things you need to know about heart attacks.

Type O: Lower risk of blood clots
Considering that type Os have lower quantities of the proteins that help blood coagulate, they're also less likely to suffer from blood clots. (The downside is that blood clotting helps prevent excessive bleeding.) That said, there are many things that cause blood clots. 'It shouldn't be assumed that being an O blood type means an individual is 'protected' or an A blood type is at higher risk,' says American Society of Hematology Councillor Terry B. Gernsheimer, MD. Here are the blood clot symptoms you should definitely not ignore.

Type O: Fertility problems
O may be the most common blood type, but it can interfere with pregnancy. As research from the Albert Einstein College of Medicine notes, O's were twice as likely to have levels of follicle stimulating hormone (FSH)—levels that were high enough to indicate low ovarian reserve.

Non-O type: An increased risk of gastric cancer
Another interesting finding from the BMC Medicine study: Non-O blood types (A, B, or AB) also had an increased risk of gastric cancers, possibly due to an inflammatory response to H. pylori bacteria, the researchers write. (The bacteria is a cause of gastric ulcers.) Here's how to know if your pain is from an ulcer.

Non-O type: Deep vein thrombosis
Because of differences in clotting, A/B blood types are 31 percent more likely to suffer from venous thromboembolism—a clot that forms in the deep veins of the leg, groin, or arm—compared to the O type, according to research from the University of Minnesota. Learn how to prevent deep vein thrombosis while on an airplane.

Type AB: Memory loss
Though AB is the least common blood type, research suggests that people with AB are 82 percent more likely to develop cognitive issues in the future. It may be because this blood type comes along with higher levels of factor VIII, the study authors say.

Type A or B: Diabetes
People with A or B blood type have up to 21 percent greater risk of developing type 2 diabetes, per Diabetologia. (B positive had the highest odds.) While researchers note that it's not exactly known why, one thought is that it may be that blood type influences the GI microbiome, which can affect glucose metabolism and inflammation.

It can't tell you about your perfect diet
You may have heard people talk about a trendy diet: that eating and avoiding certain foods based on your blood type can boost your health and lower your risk of disease. However, a 2013 review in the American Journal of Clinical Nutrition concluded that there's no evidence that proves these types of diets actually work. Another study found that although following the diet may work, it has nothing to do with someone's specific blood type. Find out more aboutblood type diets.

It probably won't tell you about your personality
There's a theory that your blood type can explain why you act the way you do. While that largely hasn't been proven, one Japanese study found that some traits differed between blood groups. People with type A, for instance, scored higher on persistence compared to type B or O. Even the researchers note that there's not enough data to prove the connection, however. Until we know more, looks like your blood type can't be the scapegoat for your behavior.

What to know about blood type research
Keep in mind that the research linking blood type and health conditions looks at population studies, so it can only find an association—not that your blood type is the cause. 'The risk for any one person is multifactorial,' notes Dr. Gernsheimer. That means your daily habits—what you eat, your activity level, how you handle stress, your family history—make a huge difference in your individual risk.

You don't have to overhaul your life because of your blood type
Your blood type certainly doesn't seal your fate when it comes to your health. 'It's important to understand that blood groups also vary in different ethnicities and within ethnic groups depending on where they settled during migrations. These differences in cultures may lead to differences in diet and lifestyle that further affect risk,' says Dr. Gernsheimer.Even though there are many ways your blood type can influence your health, 'there isn't good evidence that one's lifestyle should be altered because of it,' says Dr. Gernsheimer. And it's not up to you to have this info should you need a blood transfusion, she says. Healthcare personnel wouldn't rely on your word for it—they'd check it in advance. All that to say: don't get down if you're not in the know. Next, learn obscure facts about your own body you never knew.

Scientists Turning Type A Blood Into Universal Type O

Abbey Interrante  4 hrs ago

Quote
Bacteria found in the human gut could help save lives by transforming Type A blood into Type O blood.

At a meeting of the American Chemical Society on Tuesday, Steve Withers of the University of British Colombia presented his new research. Newly discovered bacterial enzymes that were kodged in the human gut could provide a groundbreaking option for treatment, New Scientist reported.

There are four blood types: A, B, AB and O. Even though the red blood cells in each type are similar, they have different sugars, or antigens, on the surface of the cells, according to the American Red Cross. Type A blood cells have A antigens, while Type B blood cells have B antigens. Type AB has both A and B antigens, but O has no antigens at all, which makes O compatible with the other main blood types because it’s not bringing in any antigens that the new blood won't recognize.

There’s also a protein called the RH factor, which when present makes someone’s blood type positive, and when not present can make it negative. Blood that is negative can be given to people who have either negative or positive blood, which is why Type O negative blood is the universal donor.

“We knew that those same sugars that are on our red blood cells are also produced on the lining of the gut wall,” Withers told New Scientist. His team began searching for enzymes in human feces that had the ability to strip a cell of its sugars because those enzymes likely fed on sugars when they were in the gut.

The scientists learned that the enzymes extract sugars from proteins on the gut wall, called mucins. The sugars in mucins are very similar to the antigens on red blood cells. When the team added the enzymes to Type A negative blood, it ate the antigens, and the blood turned into Type O negative.

“This technique could broaden the utility of the current blood supply because O type blood can be donated to anybody,” Steve Withers told New Scientist. This new method could mean that people in areas with low resources, such as rural areas or places facing war, could transform available blood into the blood that anyone could use.

Similar processes are currently used to change blood, but this new method is 30 times faster. The team still needs to test the enzymes further to make sure there are no unintended consequences before using this technique in clinical settings.

Researchers crack the code of the final blood group system

Summary:
Ever since the blood type was discovered in 1962, no one has been able to explain why some people become Xga positive while others are Xga negative. But now, researchers have finally solved the mystery.

FULL STORY
Ever since the blood type was discovered in 1962, no one has been able to explain why some people become Xga positive while others are Xga negative. But now, researchers at Lund University in Sweden have finally solved the mystery, and their study is being published in the scientific journal Blood.

In case of a blood transfusion, it is important to know the blood type of both the donor and the patient. The reason is that you want them to match in order to reduce the risk of side effects. The well-known blood group systems ABO and Rh are prioritised as they are clinically the most important. However, other blood types can also cause problems.

Over the past ten years, researchers have developed methods to determine many of our blood types using DNA technology rather than by red blood cells. Modern technology is particularly important for patients who have received large amounts of blood or those who need blood often, as their blood becomes a mixture consisting of several different donors. This makes it difficult to determine the patient's own blood type.

However, for the DNA tests to work, the genetic cause of each blood type system must be known. This is the case for the majority of our 36 systems, including ABO and Rh.

In practice, it's actually only one system -- the Xg system -- that has continued to elude physicians and researchers over the years. A third of all men and a tenth of all women lack the Xg protein that carries the mysterious blood type Xga on their red blood cells, i.e. they are Xga negative. Furthermore, the protein's function is still unknown. The Xga blood type was discovered in New York back in 1962, but it wasn't until now that researchers in Lund managed to figure out why a large part of the population lacks Xga.

"We enjoy solving old mysteries where others have failed, so we combined computer-based analyses with laboratory experiments," explains Martin L Olsson, professor at Lund University and medical consultant at the Nordic Reference Laboratory for Blood Group Analysis, who conducted the study.

Although this blood type was the first to be linked to a specific chromosome in humans (sex chromosome X), Xg is the last blood type system to surrender its secret and thus be included in modern genetic testing.

"We used a bioinformatic strategy to find the underlying genetic cause," says doctoral student Mattias Möller, who used to work in the tech industry before making a switch to become a physician and blood researcher.

"I sat down at my computer and analysed and compared results from previous major studies, partly using my own tools, to solve the problem. Then my colleagues took over to confirm my findings through experiments in a lab environment," says Mattias Möller.

The lab experiments showed that a small variation close to the XG gene prevents the transcription factor GATA1 from binding to the DNA, which is why the Xg protein cannot be expressed in the red blood cells in some people. The finding makes it possible finally to determine also the Xga blood type using genetic typing/methods.

"Now we are in the process of introducing it in the clinic and aim to find out what this exciting protein does and the consequences of the fact that so many of us don't have it," concludes Martin L Olsson.

Xga Blood Group System

Quote
Inheritance
The Xga (or Xg) system is one of the few BGS whose genes are sex-linked. Because the system has little significance other than its mode of inheritance, it is included in this chapter. As the name implies, the gene locus is on the X chromosome. Inheritance is controlled by two alleles (Xga and Xg) with Xga being dominant and Xg being recessive (or an amorph).

Because the system is sex-linked, the frequency of the Xg(a+) phenotype varies in males and females. The female frequency is 88% and the male frequency is 66%.

Males can be positive (XgaY) or negative (XgY). If positive, they are said to be hemizygous.

Females, if positive, can be homozygous (XgaXga) or heterozygous (XgaXg). XgXg females are Xg(a-).

Hi all,

This is a cool thread but there are a LOT of misconceptions herein.

For one thing just to give you something to chew on:

AB negative, though statistically low in the US .06% in not the rarest blood type (in practice, but yeah by the numbers which is not the whole story) nor is it ANY problem finding blood for this type.

AB red cells are known as the "Universal RECIPIENT of blood cells" and the "Universal donor of Plasma. Why? Type AB can get A, B, O or AB cells (packed cells).

AB can donate their plasma to A, B, O, AB positive or negative.

O cells are known as the Universal Donor of cells (usually we only give credit to Rh if it's a female at childbearing age in an emergency), and you could give them any type of plasma but we don't because we usually have an over abundance of O plasma.

So if your spouse is AB negative do not despair, they can get any type of packed cells, especially if they are male (in an emergency like a unknown trauma patient) we would give them O positive packed cells and AB plasma. That way no matter what type they are that would be OK.

If the emergency is a female within childbearing age we always err on the side of caution and give the O negative packed cell and as needed AB plasma until we get a sample and find out their type. If they turn out to be, say O positive, we switch them to O pos packed cells and O plasma, no problem.

We try to get a sample before they give them any blood, sometimes just moments before so we can find a type undiluted by emergency blood transfusion

Actually in practice the rarest type of blood on the SHELF is B negative. We usually have an excess of AB positive packed cells and AB negative packed cells and since people are rarely that type we often rotate those back to the Red Cross or blood supplier.

B negative we usually only had a few of those so if someone came in as an emergency say gunshot wound we would flip the to O pos packed cells (male) or O negative depending on need or supply and as they finish up we would try to give the last 8 units as their type or O negative packed cells because in most people the blood is going through them too quickly to mount an antigen response to the D-antigen.

HTH.

Also, on the very odd Rh null phenotype, if someone came in who had never been pregnant or transfused we would give them Rh (c-e-) because the phenotype is (dce/dce) (Rh negative), and the little c antigen is the most antigenic and then the little e is probably next. Big C and Big E are not terribly antigenic means that even though the immune system sees them, it won't react very strongly.

But once the Rh null is pregnant or transfused, then they are at risk fore producing a host of Rh antibodies and they should be storing their own blood as frozen washed packed cells in the -80 freezer (lasts 10 years).

The reason we say 'pregnant' is that the baby depending on the father's genotype will produce an antigenic response in the mother if there is any feto-maternal bleed (kind of uncommon but still a risk). So if you are a pregnant female and you find you have Rh null, you should donate about 4-6 unit in case you have what we call a placenta prevue (massive rupture of the placenta) also rare.

HTH
