Most times, the infection remains inactive. But each year about eight million people develop active cases of TB, usually in their lungs. Two million people die of of it. The disease has increased with the spread of AIDS and drug-resistant forms of tuberculosis.Current treatments take at least six months. People have to take a combination of several antibiotic drugs daily. But many people stop as soon as 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 University2 led the study. 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 the 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 reductions would take place between two thousand twelve and two thousand thirty. That is, if a faster cure is developed and in wide use by two thousand twelve.The World Health Organization reductions the DOTS3 program in nineteen ninety. DOTS is Directly Observed Treatment, Short-course. Health workers watch tuberculosis patients take their daily pills to make 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 Drug Development4 says its long-term goal is a treatment that could work in as few as ten doses.2 A Biological Clock(新增)Every living thing has what sicentists call a biological clock that controls behavior. The biological clock tells plants when to form flowers and when the folwers should open, It tells insects when to leave the protective cocoons and fly away, and it tells animals and human beings when to eat, skeep and wake.Events outside the plant and animal affect the actions of some biological clocks. Scientists recently found, for example,that a tiny animal changes the color of its fur because 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 begin their long migration flight twice each year. Birdsprevented from flyin become restless when it is time for the trip, but they become calm again when the time of the flight has ended.Scientists say they are beginning to learn which parts of the brain contain biological clocks.An American researcher,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 oerson when to awaken,when to sleep and when to seek food, Scientists say there probably are other biological clock cells that control other body 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 officials 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 factory`s production.3 One Good Reason to Let Smallpox LiveIt’s now a fair bet that we will never see the total extinction 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 there in keeping these reserves?in reality, of course, it was naive to imagine that everyone would let go of such a potential weapon. Undoubtedly several nations still have a few much vials. And the last “official” stocks of lice virus bred mistrust of the US and Russia, for no obvious gain.Now American researchers have found an animal model of the human disease, opening the way for tests on new treatments and vaccines. So one again there’s a good reason to keep the virus —just in case t he disease puts in a reappearance.How do we_deal with the mistrust of the US and Russia? Simple Keep the virus under international auspices in a well-guarded UN laboratory that’s open to all countries. The US will object, of course, just as it rejects a multilateral approach to just about everything. But it doesn’t mean the idea is wrong. If the virus is useful, then let’s make it the servant of all humanity—not just a part of it.4 Diet, Alcohol Linked to Nearly One Third of CancersDiet is second only to 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 University 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 blinked to about 30 percent 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 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 answers.Early results of the study 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 EPIC study, said it is looking at dietary links to some of the most common cancers including colorectal, breast and prostate.5 Men Too May Suffer from Domestic ViolenceNearly three in 10 men have experienced violence at the hands of an intimate partner during their lifetimes, according to one of the few studies to look at domestic violence and health among men."Many men actually do experience domestic violence, although we don't hear about it often," Dr. Robert J. Reid of the University of Washington in Seattle, one of the study's authors, told Reuters Health. "They often don't tell __ and__ we don't ask. 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 behavior (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 year.Rates 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 their lives. About half of the violence the men experienced was physical.However, the physical violence men reported wasn't 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 ofwomenMen who reported experiencing domestic violence had more emotional and mental health problems than those who had not, especially older men, the researchers found.译文1.找到速效治疗剂可以更好控制结核病世界卫生组织估计全球有大约三分之一的人感染了导致结核病的病菌。
