Prevention is Better than Cure

Scientists at Imperial College, London, pointrepparttar way to stopping malaria at its source:repparttar 115619 mosquito

Malaria remains one ofrepparttar 115620 world's most intransigent diseases, causing suffering and posing serious threats to development in some ofrepparttar 115621 world's poorest countries. Transmitted throughrepparttar 115622 bite of a female mosquito (Anopheles stephensi), it affects more than 300 million people and causes more than one million deaths each year, 90 percent of which occur in Africa. According torepparttar 115623 World Health Organisation (WHO), most of these deaths are among children underrepparttar 115624 age of five. Pregnant women are also especially vulnerable to this disease, which is increasingly resistant torepparttar 115625 drugs used to treat it. Malaria is characterised byrepparttar 115626 WHO as 'both a disease of poverty and a cause of poverty'. As no effective vaccination been developed and none is onrepparttar 115627 horizon,repparttar 115628 situation seems to hold little promise for those whose lives and livelihoods are threatened byrepparttar 115629 disease.

Now progress inrepparttar 115630 field of genetics has led scientists from Imperial College, London, to maprepparttar 115631 means by which it could be eradicated - not by treatment but by prevention. Genetically modified mosquitoes that do not transmit malaria were first bred under laboratory conditions three years ago. The hope has been that such a strain, if released intorepparttar 115632 wild, would become absorbed intorepparttar 115633 native population and spreadrepparttar 115634 gene that stopsrepparttar 115635 transmission ofrepparttar 115636 malaria parasite, thus transformingrepparttar 115637 insects from 'disease carriers to disease fighters.'

Unfortunately this hope has so far been thwarted. It seems thatrepparttar 115638 transgenic mosquitoes do not haverepparttar 115639 clout to dominate over their wild relatives. Onrepparttar 115640 contrary, they quickly die out if they breed freely with their unmodified counterparts. The Imperial College Study, in whichrepparttar 115641 transgenic mosquitoes were mated with unmodified insects showed thatrepparttar 115642 beneficial gene was lost overrepparttar 115643 course of between 4 and 16 generations. Givenrepparttar 115644 short life-cycle ofrepparttar 115645 insects, this represents only a very slight time span. Infinite numbers of mosquitoes would therefore need to be released in a particular place to give them a hope of replacingrepparttar 115646 wild, parasite-riddled varieties - meaning thatrepparttar 115647 scale and cost of such an activity would probably be prohibitive.

However,repparttar 115648 scientists involved inrepparttar 115649 project, which is funded byrepparttar 115650 Wellcome Trust, are confident that what has been learnt pointsrepparttar 115651 way ahead. Now they have to carry out feasibility studies and look atrepparttar 115652 costs involved to see if they can find solutions torepparttar 115653 problems they have encountered. Surmounting these difficulties would make possible not just a malaria-free future but would also allow similar techniques to be applied in fighting yellow fever and dengue. The obstacle race Professor Andrea Crisanti, who has recently jointly published a paper on these studies, acknowledges that further work is needed onrepparttar 115654 molecular genetics ofrepparttar 115655 problem: 'an increasingly important challenge is to studyrepparttar 115656 population biology of transformed mosquitoes and understand how a beneficial gene can be driven through a wild population,' he says. He recognises too that public concern over genetic modification in general means thatrepparttar 115657 environmental and bio-safety aspects ofrepparttar 115658 work will play an important role. The population studies being undertaken by himself and his team will be essential torepparttar 115659 regulatory processes associated with such issues.

When your doctor asks, "What Medications are you Taking," Do You Truly Know? © By Lena Sanchez

What if you don't need heart medication and you are getting it anyway? How about blood pressure medication, maybe birth control? Think aboutrepparttar consequences!

If you are drinking or bathing in tap water you may be getting prescriptions prescribed for someone else and you won't ever know it! The pharmacist isn't messing up nor your doctor, read on and see what prescriptions you are really taking!

If you are having health problems and drinking or bathing in Tap water, could good old water berepparttar 115618 culprit? May be!

A 2000 U.S. government analysis showedrepparttar 115619 nation's waterways are awash in chemicals used in beauty aids, medications, cleaners, and foods. Amongrepparttar 115620 substances found were caffeine, contraceptives, painkillers, insect repellent, perfumes, and nicotine. How much? All they know for sure it's unacceptable levels! That was 2 one-half years ago and more have been added since?

Scientists sayrepparttar 115621 problem is that these substances largely escape regulation and defy municipal wastewater treatment facilities. Allrepparttar 115622 long-term effects of exposure are still unclear and there are not many studies being done to find out. The few studies that have been published are not good news!

Compounds of all kinds, and more being added daily, are sold on supermarket shelves and found in virtually every medicine cabinet and broom closet as well as at farms and factories. And they are flushed or rinsed downrepparttar 115623 drain every day. But they do not disappear or break up, researchers warns.

Having worked in medical offices for twenty plus years I can attest that this does happen... We were taught to flush outdated medications downrepparttar 115624 toilet. We all assume our government local, federal and state will have something to clean our water. Boy what ostriches we are sticking our heads inrepparttar 115625 sand. I can only regret my actions that contributed to this problem and will absolutely never do it again...

Look at allrepparttar 115626 medical offices andrepparttar 115627 thousands and millions of outdated medications, in each office, dumped into your tap water? Not a pretty thought!

This isrepparttar 115628 first generation to be raised with such horrendous chemical dangers and we still do not knowrepparttar 115629 whole affect that is being put upon us. My grandmother always said, "Better to be safe than sorry." I thought she was just old but you know she was smarter than I gave her credit for. Now it's my turn to pass onrepparttar 115630 wisdom gained by age. But at least I have lived to age because my childhood was free ofrepparttar 115631 poisons that my children and grandchildren have been and are subjected to daily!

Are you and everyone in your family going to be so lucky? Not unless you watch what goes into and on your body!

What some say is good for us isn't!

A study, fromrepparttar 115632 Journal of Brain Research Vol. 784, 1998, indicates that low levels of fluoride inrepparttar 115633 drinking water of animals - equal torepparttar 115634 amount of fluoride found in fluorinated water systems- causes damage to brain tissue, similar torepparttar 115635 pathological changes found in humans with Alzheimer¹s and other severe forms of dementia.
