People with the rare AB blood type, present in less than 10 percent of the population, have a higher than usual risk of cognitive problems as they age. The aim of the study is to understand the heavy stroke toll seen in the southeastern U. Cushman’s team focused on information collected twice yearly via phone surveys that evaluate cognitive skills such as learning, short-term memory and executive function. The researchers zeroed in on individuals who showed significant declines on at least two of the three phone survey tests. When they compared that cognitively declining group with participants whose mental muster remained robust, researchers found that impairment in thinking was roughly 82 percent more likely in individuals with AB blood type than in those with A, B or O blood types, even after taking their race, sex and geography into account. The finding was published online last September in Neurology. The seemingly surprising result has some precedent: Yet these cardiovascular consequences are believed to be linked to the way non-O blood types coagulate, which did not seem to contribute to the cognitive effects described in the new study. The researchers speculate that other blood-group differences, such as how likely cells are to stick to one another or to blood vessel walls, might affect brain function. In the meantime, those with AB blood need not panic about their future cognitive wherewithal, she says, noting that all our brains are apt to benefit from a healthy diet, awareness of our risk factors for heart disease and stroke, and regular exercise for the body and brain.
Things You Should Know About O Negative Blood Type
Find out what your blood type says about your personality and health. Could blood type provide a key to wellness and even affect our personality? In Japan extensive research on blood type and personality began more than 60 years ago. Blood type can be a valuable clue for understanding your own uniqueness.
Remember that your blood type doesn’t consist of just one protein like type A or B, but 32 blood group systems like Rhesus positive or negative.
I recently learned that I have Rh- blood I’m A- , and was idly looking into blood types on Wikipedia. Looking just a little further, I found a bunch of crackpot-looking sites that try to explain how people got Rh- blood, and what weird abilities they possess as a result. I managed to find one site that seemed at least less laughable, which suggested that interbreeding with Homo neanderthalensis or possibly Homo sapiens neanderthalensis, since the site seemed to indicate that there was some question about how different H.
Indeed, most sites e. I am not a biologist, or an anthropologist, or a life-science kind of guy at all. Lots of the pseudo-scientific, paranormal, etc. What, if any, is the current scientific understanding of the origin, or source, of rhesus negative blood in human beings?

The human immune system will attack any foreign substance entering the body by generating antibodies which will attack and destroy them. Hence, these substances which trigger antibody creation are called antigens. Now there are various useful sugars and proteins on the surface of our red blood cells, which our immune system might otherwise mistake to be foreign bodies and generate antibodies to kill them.
Yes that is true, O rhesus negative blood was the first blood of humans. The ancient shamanistic tribes that inhabited the earth a long time before we created the .
Here is the original article: Around six months ago I have asked on my Facebook fanpage if people knew their genetic heritage. Only a few people replied on the public page, but in the following months more and more people would contact me in private as some of them have become inspired through the question to find out.
Within my network, around 90 percent of all members are female, so the feedback I have received regarding genetic heritage pinpoints mtDNA, the maternal line. Out of the first 30 people who told me their haplogroup all rh negative people , 18 were either haplotype J, JT, T, J1 or J2. T is the Mesopotamian marker. J2 Jewish and J1 Arabic descending from J.
And J itself stems from JT which pinpoints the ancient Etruscans. One curiousity worth noting is that according to the Bible, Abraham was born in Ur, Sumer. He was the forefather of the Hebrews and the Arabs. So if he was a typical J Sumerian and his offspring was J1 and J2, then the story made sense in that regard. Initially I have found a study where 5, year old Basque graves were being examined and around 15 percent had haplogroup J as in J1c1 and J2a also known as the Cohen marker , meaning the further you go back within the Basque population, the higher the percentage of haplotype J becomes:

The reasons for chemtrailing PostMon Dec 27, 2: Now onto my posting. The reasons for chemtrailing are many and varied.
If you are Rh-negative, many of the characteristics of your primary blood type will apply, in addition to a few extra. For example, Rh-negative individuals have a higher IQ than average as well as intense empathic qualities.
You may know then whether you are type A, B, AB, or O, which is collectively referred to as the ABO blood group and is believed to have evolved from a distant ancestor millions of years ago. Your blood type, inherited from your parents, refers to the specific antigens molecules that can cause an immune response found on the surface of your red blood cells. The ABO blood group results from one gene that has three variations: A, B, and O. Before blood typing was discovered in the early s, a blood transfusion could and often did have fatal consequences.
In the case of blood type, if a person with type A receives type B blood, for example, specific immune proteins called antibodies will respond by attacking the B antigens, causing the red blood cells to clump, which can result in death. That is, are people with certain blood types more vulnerable to developing heart disease, cancer, or diabetes? Might your blood type even affect your memory or your response to diet? Here, in brief, is what we know.
Blood type AB was associated with a 23 percent higher risk of cardiovascular disease, compared with type O, while type B was associated with an 11 percent higher risk, and type A, a 5 percent higher risk.
Blood Type Matters for Brain Health
Phenotype – B AB: However, using normal blood tests it is impossible to tell the genotype of an individual who has an A or B blood group. If a person of O blood group breeds with a person of B group all the children must be either B or O. If the child is A or AB one of the individuals cannot be the parent. In short the ABO system can prove you are not a parent but not that you are, as there are millions of other people with the same blood group.
The ABO blood group results from one gene that has three variations: A, B, and O. Blood type A has A antigens, type B has B antigens, AB (the least common type in the U.S.) has both, and O (most common) has neither.
The Enveloping Wave of Compassion? If you don’t have the Rh factor, you’re considered Rh-negative; if you have it, you’re Rh-positive. About 85 percent of people are Rh-positive, though it varies by race. For African Americans, about percent are Rh-positive, and for Asians, the figure is 98 to 99 percent. It means his or her blood can be given to anyone, regardless of blood type, without causing a transfusion reaction. Then this group spread heavily into the area of what is now Spain, England, Ireland, etc.
The Process of Alloimmunization During the birthing process, blood cells from the unborn child can escape into the mother’s bloodstream. These cells are recognized as foreign if they are a different blood type from the mother and a natural rejection process will ensue with the formation of antibodies. The process is known as red cell alloimmunization. If a Rh-negative woman conceives a child with a Rh-positive partner, the potential exists for the child to inherit its father’s Rh-positive blood type.
Rh Negative Blood and Pregnancy
Over to Kyra… Hi there! Ridgway has discussed here on her blog and in her book. Ridgway has graciously offered me the chance to explain more about the theory, which I was very pleased to accept.
A negative blood type cannot give birth to a positive blood type baby. 5 years ago. Dark-HunterJenn. Reply 0 Likes. I am a bit late, but as a Mom I thought I would add something. I am O- and when I was carrying my son (16 years ago) the doctors spoke to me about the problems that COULD happen if I didn’t have 3 shots of what is called RhoGAM.
As am I, two markers one from each parent, active HH. Debbie Wareing I assume from that statement you are rh neg! What makes you think that Christ would have had relations with Mary Magdeline or any other woman for that matter. That would be a total contradiction of His teachings! Debbie Wareing There are a number of scriptures in the new testament that indicates sexual immorality to be unclean, to abstain from, neither let us practice etc.
It includes adultery, prostitution, sexual relations between unmarried individuals, homosexuality and bestiality. This of course is unlawful in the eyes of God, man made laws of course vary from country to country and maybe some laws of man do not acknowledge them all, as unlawful. Secondly, how can you possibly say that:
