1、microscopicmess349Better Control of TB Seen If a Faster Cure Is FoundThe World Health Organization estimates that about one-third of all people are infected with bacteria that cause tuberculosis. Most times, the infection remains inactive. But each year about eight million people develop active case

2、s of TB, usually in their lungs. Two million people die of it. The disease has increased with the spread of AIDS and drug-resistant forms of tuberculosis.Current treatments take at least six months. Patients have to take a combination of several antibiotic drugs daily. But many people stop as soon a

3、s they feel better. Doing that can lead to an infection that resists treatment. Public health experts agree that a faster-acting cure for tuberculosis would be more effective. Now a study estimates just how effective it might be. A professor of international health at Harvard University led the stud

4、y. Joshua Salomon says a shorter treatment program would likely mean not just more patients cured. It would also mean fewer infectious patients who can pass on their infection to others.The researchers developed a mathematical model to examine the effects of a two-month treatment plan. They tested t

5、he model with current TB conditions in Southeast Asia. The scientists found that a two-month treatment could prevent about twenty percent of new cases. And it might prevent about twenty-five percent of TB deaths. The model shows that these reduction would take place between two thousand twelve and t

6、wo thousand thirty. That is, if a faster cure is developed and in wide use by two thousand twelve.The World Health Organization developed the DOTS program in nineteen ninety. DOTS is Directly Observed Treatment, Short-course. Health workers watch tuberculosis patients take their daily pills to make

7、sure they continue treatment.Earlier this year, an international partnership of organizations announced a plan to expand the DOTS program. The ten-year plan also aims to finance research into new TB drugs. The four most common drugs used now are more than forty years old.The Global Alliance for TB D

8、rug Development4 says its long-term goal is a treatment that could work in as few as ten doses.A Biological ClockEvery living thing has what scientists call a biological clock that controls behavior. The biological clock tells plants when to form flowers and when the flowers should open. It tells in

9、sects_ when to leave the protective cocoons and fly away，and it tells animals and human beings when to eat, sleep and wake. Events outside the plant and animal affected the actions of some biological clocks. Scientists recently found, for example, that a tiny animal changes the color of its fur beca

10、use of the number of hours of daylight. In the short days of winter, its fur becomes white. The fur becomes gray brown in color in the longer hours of daylight in summer. Inner signals control other biological clocks. German scientists found that some kind of internal clock seems to order birds to b

Scientists say they are beginning to learn which parts of the brain contain biological clocks. An American res

12、earcher, Martin Moorhead, said a small group of cells near the front of the brain seems to control the timing of some of our actions. These cells tell a person when to awaken，when to sleep and when to seek food . Scientists say there probably are other biological clock cells that control other body

13、activities. Dr. Moorhead is studying how our biological clocks affect the way we do our work. For example, most of us have great difficulty if we must often change to different work hours. It can take many days for a human body to accept the major change in work hours. Dr. Moorhead said industrial o

14、fficials should have a better understanding of biological clocks and how they affect workers. He said such understanding could cut sickness and accidents at work and would help increase a factorys productionOne Good Reason to Let Smallpox LiveIts now a fair bet that we will never see the total extin

15、ction of the smallpox virus. The idea was to cap the glorious achievement of 1980, when smallpox was eradicated in the wild, by destroying the killer virus in the last two labs that are supposed to have it one in the US and one in Russia. If smallpox had truly gone from the planet, what point was th

16、ere in-keeping these reserves ?In reality, of course, it was nave to imagine that everyone would let go of such a potent potential weapon.1 Undoubtedly several nations still have a few vials.And the last “official” stocks of live virus bred mistrust of the US and Russia,for no obvious gain.Now Ameri

17、can researchers have found an animal model of the human disease, opening the way for tests on new treatments and vaccines. So once again theres a good reason to keep the virus just in case the disease puts in a reappearance.How do we deal with the mistrust of the US and Russia? Simple Keep the virus

18、 under international auspices in a well-guarded UN laboratory thats open to all countries, The US will object, of course, just as it rejects a multilateral approach to just about everything. But it doesnt mean the idea is wrong. If the virus is useful, then lets make it the servant of all humanity n

19、ot just a part of it.Diet, Alcohol Linked to Nearly One Third of CancersDiet is second only to1 tobacco as a leading cause of cancer and, along with alcohol, is responsible for nearly one third of cases of the disease in developed countries, a leading researcher said on Tuesday.Dr. Tim Key, of the U

20、niversity of Oxford, told a Cancer conference that scientists are still discovering how certain foods contribute to cancer, but they know that diet, alcohol and obesity play a major role.“Five percent of cancers could be avoided if nobody was obese,” he said.While tobacco is linked to about 30 perce

21、nt of cancer cases, diet is involved in an estimated 25 percent and alcohol in about six percent.Obesity raises the risk of breast, womb, bowel and kidney cancer, while alcohol is known to cause cancers of the mouth, throat and liver. Its dangerous impact is increased when combined with smoking.Key

22、told the meeting of the charity Cancer Research UK that other elements of diet linked to cancer are still unknown but scientists are hoping that the EPIC study, which is comparing the diets of 500,000 people in 10 countries and their risk of cancer, will provide some answersEarly results of the stud

23、y have revealed that Norway, Sweden and Denmark have the lowest consumption of fruit and vegetables among European countries while Italy and Spain have the highest. Eating at least five portions of fruit and vegetables a day is recommended to reduce the risk of cancer.Key, principal scientist on the

24、 EPIC study, said it is looking at dietary links to some of the most common cancers including colorectal, breast and prostate.Men Too May Suffer from Domestic ViolenceNearly three in 10 men have experienced violence at the hands of1 an intimate partner during their lifetimes, according to one of the

25、 few studies to look at domestic violence and health among men.Many men actually do experience domestic violence, although we dont hear about it often,” Dr. Robert J. Reid of the University of Washington in Seattle, one of the studys authors, told Reuters Health. “They often dont tell and we dont as

26、k. We want to get the message out to men who do experience domestic violence that they are not alone and there are resources available to them.”The researchers asked study participants about physical abuse and non-physical abuse, such as threats that made them fear for their safety, controlling beha

27、vior ( for example, being told who they could associate with and where they could go) , and constant name-calling.Among men 18 to 54 years old, 14.2 percent said they had experienced intimate partner violence in the past five years, while 6.1 percent reported domestic violence in the previous yearRa

28、tes were lower for men 55 and older, with 5.3 percent reporting violence in the past five years and 2.4 percent having experienced it in the past 12 months.Overall, 30.5 percent of men younger than 55 and 26.5 percent of older men said they had been victims of domestic violence at some point in thei

29、r lives. About half of the violence the men experienced was physical.However, the physical violence men reported wasnt as harsh as that suffered by women in a previous study; 20 percent to 40 percent of the men rated it as severe, compared to 61 percent of women.Men who reported experiencing domesti

30、c violence had more emotional and mental health problems than those who had not, especially older men, the researchers found.Bringing Nanotechnology to Health Care for the Poor納米保健技術(shù)走向貧困國家Nanotechnology uses matter at the level 納米技術(shù)的應(yīng)用對象都是分子級和原子級的物質(zhì)。如今，長度為一納米，即十億分之一米的粒子已被開發(fā)出多種用途，如制造美容產(chǎn)品和抗污型服裝等。但其中一個

31、領(lǐng)域科學家認為潛力尤為巨大，那就是醫(yī)藥領(lǐng)域。在上周于華盛頓Woodrow Wilson國際中心召開的一個項目會議上，科學家們探討了如何將納米技術(shù)應(yīng)用于貧困國家人口保健的事宜。來自多倫多大學的Peter Singer聲稱一項名為量子點的納米技術(shù)可被應(yīng)用于瘧疾的診斷。相對于傳統(tǒng)的僅用顯微鏡觀察血液樣本的方法，此技術(shù)要先進得多。由于貧困國家往往沒有條件應(yīng)用此項新技術(shù)，許多健康人被誤診為瘧疾患者，而藥物的濫用又導致了抗藥性的產(chǎn)生。所謂量子點是指一些被激活后會發(fā)光的粒子，如今科學家正在研究為它們編程的方法，以便當靶分子存在的時候就能夠通過發(fā)光來診斷疾病。納米技術(shù)的優(yōu)越性不光體現(xiàn)在疾病的診斷，還包括疾病的

32、治療。國立衛(wèi)生研究所的Piotr Grodzinski與大家共同探討了如何運用納米技術(shù)來增強藥效。以一些已經(jīng)使用了納米技術(shù)的抗癌藥物為例，他指出，如果藥物可以針對癌癥病灶而不是整個人體，治療所需藥量就會大大減少，副作用也會降低。Andrew Maynard是Woodrow Wilson中心新興的納米技術(shù)工程部骨干科學家，他注意到巴西、印度、中國及南非正在開發(fā)可被貧困園家所應(yīng)用的納米技術(shù)。與此同時他指出，與較大分子不同，納米材料的顆粒在人體內(nèi)和體外環(huán)境中的作用可能有所不同，因此納米技術(shù)的應(yīng)用存在一定風險，若要深入研究這些風險則需要更大的資金投人。research is needed to bet

44、新生兒，且即使幸存下來，其成年后患很多疾病如心臟病和糖尿病的幾率也會高于常人。世界衛(wèi)生組織估算，每年全世界有2，000萬體重過輕的嬰兒誕生，其中有90%出生在發(fā)展中國家。此次研究試驗在坦桑尼亞首都達累斯薩拉姆舉行，共有4，200名懷孕婦女參加了實驗她們服用的多維制劑包括所有B族維生素、維生素C和維生素E，同時還包括劑量超出發(fā)達國家給婦女的建議服用量數(shù)倍的鐵和葉酸鹽。因為孕期婦女較常人更容易發(fā)生維生素和礦物質(zhì)攝人不足的現(xiàn)象，尤其是在發(fā)展中國家。作為對照組，研究者給另外4，000名孕婦服用了不含有維生素的安慰劑。來自美國和坦桑尼亞的科學家們共同撰寫了實驗報告，并刊登在新英格蘭醫(yī)學雜志上，其中來自哈

45、佛大學公共衛(wèi)生學院的Wafaie Fawzi為此次研究的組織者。參加實驗的所有懷孕婦女均非艾滋病病毒攜帶者。而在更早的來自坦桑尼亞的研究報告中科學家曾指出，每日補充多維制劑對于已感染艾滋病的孕婦來說是一種減少胎兒死亡幾率的成本較低的方式。研究同時檢測到，孕婦在服用多維制劑后其血液中的淋巴細胞水平將會上升，而淋巴細胞可以增強人體免疫系統(tǒng)抵御傳染病的功能。此次新的研究試驗表明，補充多維制劑可以顯著降低新生兒體重過輕的概率。服用維生素的孕婦組中，過輕嬰兒的比重為總數(shù)的8%，而服用安慰劑的對照組中，過輕嬰兒的-比重接近9.5%。雖然對于降低孕婦早產(chǎn)率和死胎率方面，維生素的作用并不明顯。最后，科學家呼吁

52、此，一些工程師正在重新設(shè)計這種欠合理的車把，以使其更安全。賓夕法尼亞州費城的兒童醫(yī)院的生物工程師Kristy Arbogast和她的同事開始，做這個項目是在一項研究有了結(jié)果之后，這項研究的結(jié)果表明在過去的30年里，超過1/3的兒童腹部受重傷的情況起因于自行車事故。她說：“要做的工作就是找出受傷的原因及其對策?！蓖ㄟ^訪問這些孩子和他們的家長，Arbogast和她的同事得以推想其中的許多事故，并且確認一個共同的機械裝置造成了這些嚴重傷害。他們發(fā)現(xiàn)大部分傷害發(fā)生在孩子慢速撞到某種使他們跌倒的障礙物的時候。為了保持平衡，他們把車把轉(zhuǎn)過90度但是他們的沖力使他們壓進車把一端中。然后車子摔倒，車把的另一頭
