Once-daily Pill
Could Simplify HIV Treatment{{/B}} Bristol-Myers Squibb and Gilead
Sciences have combined many HIV drugs into a single pill. Sometimes the best
medicine is more than one kind of medicine. Malaria, tuberculosis and HIV/ AIDS,
for example, are all treated with {{U}}(51) {{/U}} of drugs. But that
can mean a lot of pills to take. It would be {{U}}(52) {{/U}} if drug
companies combined all the medicines into a single pill, taken just once a
day. Now, two companies say they have done that for people just
{{U}}(53) {{/U}} treatment for HIV, the virus that causes AIDS. The
companies are Bristol-Myers Squibb and Gilead Sciences. They have {{U}}(54)
{{/U}} a single pill that combines three drugs currently on the market.
Bristol-Myers Squibb sells one of them {{U}}(55) {{/U}} the name of
Sustiva. Gilead combined the {{U}}(56) {{/U}}, Emtriva and Viread, into
a single pill in two thousand four. Combining drugs involves
more than {{U}}(57) {{/U}} issues. It also involves issues of
competition {{U}}(58) {{/U}} the drugs are made by different companies.
The new once-daily pill is the result of {{U}} (59)
{{/U}}is described as the first joint venture agreement of its kind in the
treatment of HIV. In January the New England Journal of
Medicine4 published a study of the new pill. Researchers compared its
{{U}}(60) {{/U}} to that of the widely used combination of Sustiva and
Combivir. Combivir {{U}}(61) {{/U}} two drags, AZT and 3TC. The
researchers say that after one year of treatment, the new pill suppressed HIV
levels in more patients and with {{U}}(62) {{/U}} side effects. Gilead
paid for the study. Professor Joel Gallant at the Johns Hopkins School of
Medicine in Baltimore, Maryland, led the research. He is a paid adviser to
Gilead and Bristol-Meyers Squibb as well as the maker of Combivir, Glaxo Smith
Kline. Glaxo Smith Kline reacted {{U}}(63) {{/U}} the
findings by saying that a single study is of limited value. It says the
effectiveness of Combivir has been shown in each of more than fifty
studies. The price of the new once-daily pill has not been
announced. But Gilead and Bristol-Myers Squibb say they will provide it at
reduced cost to developing countries. They plan in the next few months to ask
the United States Food and Drug Administration9 to {{U}}(64) {{/U}} the
new pill. There are limits to who could take it because of the
different drugs it contains. For example, {{U}}(65) {{/U}} women are
told not to take Sustiva because of the risk of birth disorders. Experts say
more than forty million people around the world are living with
HIV.

单选题A Trip
Every year New Zealanders living in London can be seen loading up
Kombi
vans and heading off to experience the "classic European holiday". The trip usually starts in the north of France, after crossing the channel from Dover in England to Calais, driving down through France, over the Pyrenees into Spain, west into Portugal and then across the Continent to Italy and often beyond.
There are numerous reasons young New Zealanders take this rite of passage—as well as seeing all the fantastic sights and tasting the delights of Europe"s food and wine,
it
"s relatively inexpensive. The Kombi is transport and accommodation all in one, cutting down significantly on costs.
There is just one problem. As the Kombis become "antique", these trips are usually punctuated with numerous roadside sessions as the van sits idle, in no hurry to start, while you swelter in the hot sun. But do not let this deter you. Travelling Europe in your own vehicle means no public transport schedules to cramp your style, the ability to explore the quaint, off-the-beaten-track villages where the "real" locals live, freedom to not have to book accommodation in advance—you can nearly always get a campsite and can load your vehicle with cheap, fantastic regional wines and souvenirs. With these bonuses in mind, here are some suggestions for planning the great Europe road adventure. The key to a pleasurable driving experience is a good navigator and a driver with a cool head. If you do not feel relaxed driving around New Zealand"s cities and highways, then you probably will not enjoy driving around Europe. As copilot to the driver, you need to read (and understand) maps, look out for turn-offs and keep the music playing. Language is not a big problem once a few essential terms are mastered. The biggest challenge is in the cities, where traffic can be chaotic and elaborate one-way systems and narrow, cobbled alleyways can make finding your destination hard work. It can be easier to leave the vehicle on the outskirts of town or in a camping ground and use public transport. This also avoids paying for costly parking.
