Blood Group For Lower Malaria Risk

 

The most common blood type in Indians seems to provide better protection against the most deadly form of malaria. British scientists have found that people with blood group O – around 38% of the Indian population – are naturally protected from some of the most severe forms of the disease, which kills around two million people annually across the globe……....click  & see

A team from Edinburgh University, with researchers in the US, Mali and Kenya, studied African children and found that those with this blood type were two-thirds less likely to experience coma or life-threatening anaemia conditions synonymous with severe malaria.

This discovery now brings hope of developing drugs which mimic the properties of red cells. In fatal malaria, it is often found that red blood cells infected by parasites block blood vessels which supply oxygen to the brain.

The malarial parasites arm the blood cells  surface with proteins which stick to blood vessel walls. O and B are the commonest blood group among Indians. Nearly 32% of north Indians and 38% south Indians have O blood group.

“The finding that red cells present in O group blood play the major role in preventing malaria from worsening is a significant finding for India. Blood is made of antigens or proteins, some of which show protection against certain diseases. Why that occurs has not been scientifically proven yet but statistically, they have shown significant protection rates,” blood safety specialist Dr Debasish Gupta said.

Edinburgh University’s Dr Alex Rowe, whose finding was published in the journal ‘PNAS’ on Tuesday, said, “This explains why some people are less likely to suffer from life-threatening malaria than others and tells us that if we can develop a drug to reduce rosetting and mimic the effect of being blood group O, we may reduce the number of children dying from severe malaria.”

The scientists found that malaria parasites recruit healthy RBCs to stick to the parasite, encasing the infected RBC inside a so-called rosette. It makes the blockage, and the disease, worse.

However, the team’s findings suggest that group O RBCs do not easily join rosettes as the cells surface structure prevents it from sticking. The study suggests that reduced rosetting of malaria parasites is the reason why people with group O blood are less likely to suffer severe malaria.

ABO blood group types were assessed on 567 blood samples from Malian children. We found that blood group O was present in only 21% of the severe malaria cases compared to 45% of other blood groups. Rosetting was shown to be significantly lower in parasite isolates from patients with blood group O compared to non-O blood groups,” the study said.

A quick guide to food that is not only good for you but also helps you look beautiful!

CLICK & SEE

Going on a diet can be a good thing; however, there are so many newfangled diet styles out there that you just do not know which ones work and which ones are just fads.

But regardless of whatever dieting system or style you are an advocate of, there are ten kinds of food that you should be ingesting a lot of to keep yourself trim, healthy and beautiful.


Top healthy food

Fruits :
Research proves that eating at least five portions of fruits each day has very real health benefits. It can help to prevent heart diseases and some cancers.

Essential fatty acids (EFA):
Essential fatty acids, also known as the good fat, is needed to keep the cells of the body functioning properly. EFA also helps improve the condition of the skin and makes the hair and fingernails grow healthier.

Garlic :
Garlic is high in antioxidants and is a kind of food that is widely known to prevent cancer. Garlic also helps lower the body’s cholesterol levels and reduces blood pressure as well.

Green tea:
Green tea is full of antioxidants that help prevent specific kinds of cancer from developing in the body. It also pumps up the immune system and helps lower the levels of cholesterol in the body.

Green vegetables:
Vitamins A and E, as well as fibre and iron, are found abundantly in green, leafy vegetables. Vitamin A retains the moisture in the eyes, the skin and the mucous membrane, while Vitamin E helps maintain the skin’s elasticity. On the other hand, fibre improves digestion, and iron is needed for the production of red blood cells.

Milk :
Milk is the best source of calcium and vitamin D for the body. Calcium combined with vitamin D is good for keeping the bones and teeth strong, and it prevents diseases like osteoporosis.

Milk also has vitamin B2 and B12, which coaxes the body to produce more red blood cells. Red blood cells bring oxygen to the cells. Having a healthy supply of red blood cells swimming in the blood stream keeps the hair and skin looking healthier.

Soy :
Soy also has cancer-preventing antioxidants as well as Vitamin E and amino acids. It helps the skin retain its smoothness and elasticity.

Vitamin C :
Vitamin C boosts the immune system and makes the body less vulnerable to disease. Vitamin C is also an important key in the body’s collagen production, collagen being a chemical that keeps the skin elastic and wrinkle-free.

Yogurt :
Yogurt is also a good source of calcium, vitamin D and vitamin B. Aside from these, yogurt contains friendly bacteria that assists in digestion, hydrates the skin and clears the immune system.

Chocolate :
Yes, you read it right. Chocolate is an essential food to eat to keep beautiful. Chocolate encourages the production of endorphins and serotonin, hormones that generate a nice and pleasant feeling for the body. You look beautiful if you feel beautiful.

Do not forget water!
Water keeps the body hydrated. When the body is hydrated, the skin becomes smooth, supple and youthful. The hair has more shine and bounce when there is enough water in the body, and the nails are stronger. Water also flushes out the waste and toxins out of the body.
