Australian scientists have identified peanut proteins that could be translated into the world 's first treatment for the often lethal food allergy, said Professor Robyn O'Hehir from Melbourne's The Alfred hospital and Monash University on Friday. The research identified some "dominant fragments" of peanut proteins that lab tests showed were able to interact with immune cells from an allergic person to build tolerance with no sign of triggering anaphylaxis. "These dominant fragments are the best candidates for a peanut allergy vaccine," said O'Hehir who led the research. "Immunotherapy is commonly used to treat people who are allergic to wasp and bee stings (where) protein extracts from the venom are given in increasing doses to desensitize the individual, " O'Hehir said. "Until now, peanuts have been regarded as too dangerous an allergy-provoker to try immunotherapy, however the latest discovery overcomes this problem." O'Hehir said the peanut proteins could be translated into a … [Read more...] about Australian scientists in peanut allergy treatment breakthrough
Why peanut allergy so common
People allergic to peanuts may find relief in a new research by American scientists, according to Huffington Post Monday. Scientists from the Northwestern University Feinberg School of Medicine have found a way to turn off allergic responses by creating an immune system tolerant to peanuts. They attached peanut proteins, the source of the allergy, to white blood cells of mice. Then the mice's immune systems would recognise the proteins and become tolerant to them. When people eat peanuts, allergic human bodies would recognize peanut proteins as invading pathogens and trigger immune responses like throat swelling, even closing up, which can be lethal. Ditto for mice's bodies. But when peanut protein attached to the body's own cells, the immune systems would regard the peanut proteins as perfectly normal and not attack the cells, said Paul Bryce, an assistant professor involved in the study. Then the allergic responses disappeared. The research was conducted on mice. But the scientists … [Read more...] about Peanut allergies may be cured in future
Eating peanut products as a baby dramatically cuts the risk of allergy, a study reported in the New England Journal of Medicine suggests. Trials on 628 babies prone to developing peanut allergy found the risk was cut by over 80%. The King's College London researchers said it was the "first time" that allergy development had been reduced. But specialists warned at-risk families should not experiment with peanut products without medical advice. Daily nut The research team in London had previously found that Jewish children in Israel who started eating peanuts earlier in life had allergy levels 10 times lower than their equivalents in the UK. The trial focused on babies as young as four months who had already developed eczema - an early warning sign of allergies. Skin-prick tests were used to identify those who had not yet developed peanut allergy or had only a very mild response. Children under five should not eat whole peanuts, because of the risk of choking, so half were given a … [Read more...] about Early exposure ‘cuts peanut allergy’
VietNamNet Bridge – In 1968, the Beatles came out with a song called “Money Can’t Buy Me Love”. The idea that money, or material goods, doesn’t equal happiness has since become somewhat clichéd. But just because it’s a cliché, doesn’t make it less true. In survey after survey, in country after country, when people are asked about the pinnacle of their aspirations – or, simply put, ‘what do you want’ – the answer is invariably ‘to be happy’. How happiness is defined is a different story. It varies among cultures, religions and nations. A UK-based think tank called the New Economies Foundation has a definition that it has been promoting through something it calls “The Happy Planet Index” (HPI). Taking some 140 countries for which data is available, the index seeks to measure how well nations are doing at achieving long, happy, sustainable lives. You may or may not be surprised that … [Read more...] about Why is Vietnam so happy?
Feeding infants small amounts of mashed-up peanuts early in life may help them avoid developing allergies, even if they stop eating peanuts for a year in early childhood, researchers said Friday. The findings in the New England Journal of Medicine have prompted global health authorities to reconsider long-held advice that babies should avoid certain foods, amid a rise in potentially fatal peanut allergies among youths in recent years. "The early introduction of peanut to the diets of infants at high-risk of developing peanut allergy significantly reduces the risk of peanut allergy until six years of age, even if they stop eating peanut around the age of five," said the study, led by King's College London. The findings offer a follow-up to groundbreaking results announced last year from a study known as the Learning Early About Peanut Allergy (LEAP) trial, which included more than 600 children. It found that high-risk babies who ate peanuts by age 11 months experienced a substantially … [Read more...] about Eating peanuts helps infants avoid allergy, even after pause
