4、ation. Opinions are varied, mixed with fact and fiction, but one thing is clear: Open dialogue among researchers, teachers and the general public must continue as we struggle to define the relationship between our societal values and lifesciences research.When the University of Washington .and the N

5、ational Human Genome Research Institute hosted a community genetics forum last spring, questions abounded from the standing-room-only crowd about the implications of genetic research.When is information about genetic health risks most helpful? Should genetic testing results be part of medical record

6、s and how would the results be used potentially by insurance companies? How can genetic testing benefit the criminal-justice system, such as establishings guilt or innocence using DNA testing,The Human Genome Project will lead to amazing advances in medical science that will result in earlier diagno

7、sis, more-targeted treatment, and a dramatic improvement in our ability to prevent terrible diseases. Genomic medicine will mean more personalized medicine tailored to the individual.But these advances also carry inherent risks.The obvious benefits of “personalized medicine“ use of genetic tests to

8、guide preventive care and better drug prescribingare counterbalanced by the possibility that such tests could lead to discrimination by insurers or employers. And, since genetic risk is often only one of the contributing factors to disease, overemphasis on personalized medicine could burden our heal

9、th-care system with genetic tests of little or no benefit.For example, smoking, diet and exercise play major roles in the risk of diabetes and heart disease. Identification of a genetic risk for these diseases can provide specific information for more-effective preventive care, but should not detrac

This will ultimately lead to improved prevention and treatmentoften without any need for genetic testingfor many diseases. The outcome f

Thus, genomic medicine has the potential to improve the value of health care.An example of the potential of genomic medicine to improve quality and reduce cost is the work of UW researchers Mar

They recently reported the discovery of a genetic method for accurately determining the proper dosage of a common blood-thinning drug, warfarin, which often produces adverse side effects because of its highly variable activity in patients.Millions of peop

These scientists findings illustrate how the powerful DNA analysis tools of the Human Genome Project are leading to a new era of tailoring drugs and th

Genomic medicine can lead to more-precise, personalized and cost- effective health care.Medical advances always involve risk of harm, and genomic medicine is no exception. While technical issues require scientific research, we believe the challenges posed by genetic

15、 testing are far too critical to be left to the deliberation of scientists alone.All members of society should have the opportunity to engage in collaborative discussion about the benefits and harms of genetic testing. Informed public discussion is vital to continue advances that hold so much promis

16、e for improving the value of health care.Both educational resources and major organizational efforts will be needed to create opportunities for open discussion. But the most important resources are peoples time and their willingness to invest it in these discussions.Researchers, teachers and the med

Then answer the questions or complete the statements in the fewest possible words.47 During the past few weeks,

39、newspapers on both sides of the Atlantic have revealed in breathless terms the latest plan to invade Iraq.They have described massive thrusts by armour from all sides; airborne attacks to take out Baghdad; vast seaborne raids. Saddam Hussein, according to one version, will be removed by dissidents i

40、nserted into Iraq backed by US Special Forces. Alternatively, Saddam will be taken out in a precision strike.Civilian officials in the Bush administration have huffed and puffed about the “leaks“, to the amusement of the intelligence and military professionals. “One thing you can say with an awful l

41、ot of certainty,“ one told The Observer newspaper in London last week, “is that there is going to be an awful lot of deception going on over the next few months.“Deception is one of the oldest of the militarys black arts. But the fact of the existence of deception is important in itself. It is, in t

42、he terminology of these things, a “combat indicator“one of the clues that suggest things are fast on the road to getting bloody.And not all of it is necessarily deception. There have been other signs suggesting a campaign against Iraq. Manufacturers of cruise missiles and precision-guided munitions

Elsewhere, US fighting vehicles in Kuwait have been taken out of mothballs where they were left at the end of

44、 the Gulf War.The question now appears to be not whether there will be a war, but when. The answer is that in war, as other matters, timing is all.For US President George W. Bush that timing will be dictated by the demands of a domestic political agenda. With the economy in the middle of what now lo

45、oks like a doubledip recession, Bush has been left with only two policies he can sell as a success: the war against terrorism and the war against Saddam.The war against terrorism is a problematic one. Afghanistan remains a mess. Osama Bin Laden and many of his senior lieutenants remain unaccounted f

46、or.Declaring victory would not only be precipitous but dangerous. Which leaves Saddam?But when to act? Current thinking on both sides of the Atlantic is that Bush will not want to risk a war that does not begin until well into next year, as that would bring him too close to the time when he wants to

47、 be engaged in his campaign for reelection. That leaves this winter.Finally, there remains the question of what form the war might take. Insiders have insisted that the absolute minimum force requirement must be three heavy armoured divisions plus an air assault division. A likely force size, say ex
