new weapon to fight cancer
1. British scientists are preparing to launch trials of a radical new way to
fight cancer, which kills tumours by infecting them with viruses like the common
cold.
2. If successful, virus therapy could eventually form a third pillar
alongside radiotherapy and chemotherapy in the standard arsenal against cancer,
while avoiding some of the debilitating side-effects.
3. Leonard Seymour, a professor of gene therapy at Oxford University, who has
been working on the virus therapy with colleagues in London and the US, will
lead the trials later this year. Cancer Research UK said yesterday that it was
excited by the potential of Prof Seymour’s pioneering techniques.
4. One of the country’s leading geneticists, Prof Seymour has been working
with viruses that kill cancer cells directly, while avoiding harm to healthy
tissue. "In principle, you’ve got something which could be many times more
effective than regular chemotherapy," he said.
5. Cancer-killing viruses exploit the fact that cancer cells suppress the
body’s local immune system. "If a cancer doesn’t do that, the immune system
wipes it out. If you can get a virus into a tumour, viruses find them a very
good place to be because there’s no immune system to stop them replicating. You
can regard it as the cancer’s Achilles’ heel."
6. Only a small amount of the virus needs to get to the cancer. "They
replicate, you get a million copies in each cell and the cell bursts and they
infect the tumour cells adjacent and repeat the process," said Prof Seymour.
7. Preliminary research on mice shows that the viruses work well on tumours
resistant to standard cancer drugs. "It’s an interesting possibility that they
may have an advantage in killing drug-resistant tumours, which could be quite
different to anything we’ve had before."
8. Researchers have known for some time that viruses can kill tumour cells
and some aspects of the work have already been published in scientific journals.
American scientists have previously injected viruses directly into tumours but
this technique will not work if the cancer is inaccessible or has spread
throughout the body.
9. Prof Seymour’s innovative solution is to mask the virus from the body’s
immune system, effectively allowing the viruses to do what chemotherapy drugs do
- spread through the blood and reach tumours wherever they are. The big hurdle
has always been to find a way to deliver viruses to tumours via the bloodstream
without the body’s immune system destroying them on the way.
10. "What we’ve done is make chemical modifications to the virus to put a
polymer coat around it - it’s a stealth virus when you inject it," he said.
11. After the stealth virus infects the tumour, it replicates, but the copies
do not have the chemical modifications. If they escape from the tumour, the
copies will be quickly recognised and mopped up by the body’s immune system.
12. The therapy would be especially useful for secondary cancers, called
metastases, which sometimes spread around the body after the first tumour
appears. "There’s an awful statistic of patients in the west ... with malignant
cancers; 75% of them go on to die from metastases," said Prof Seymour.
13. Two viruses are likely to be examined in the first clinical trials:
adenovirus, which normally causes a cold-like illness, and vaccinia, which
causes cowpox and is also used in the vaccine against smallpox. For safety
reasons, both will be disabled to make them less pathogenic in the trial, but
Prof Seymour said he eventually hopes to use natural viruses.
14. The first trials will use uncoated adenovirus and vaccinia and will be
delivered locally to liver tumours, in order to establish whether the treatment
is safe in humans and what dose of virus will be needed. Several more years of
trials will be needed, eventually also on the polymer-coated viruses, before the
therapy can be considered for use in the NHS. Though the approach will be
examined at first for cancers that do not respond to conventional treatments,
Prof Seymour hopes that one day it might be applied to all cancers.

How a Frenchman is reviving McDonald’s in Europe
A. When Denis Hennequin took over as the European boss of McDonald’s in
January 2004, the world’s biggest restaurant chain was showing signs of recovery
in America and Australia, but sales in Europe were sluggish or declining. One
exception was France, where Mr Hennequin had done a sterling job as head of the
group’s French subsidiary to sell more Big Macs to his compatriots. His task was
to replicate this success in all 41 of the European countries where
anti-globalisers’ favourite enemy operates.
B. So far Mr Hennequin is doing well. Last year European sales increased by
5.8% and the number of customers by 3.4%, the best annual results in nearly 15
years. Europe accounted for 36% of the group’s profits and for 28% of its sales.
December was an especially good month as customers took to seasonal menu
offerings in France and Britain, and to a promotion in Germany based on the game
of Monopoly.
C. Mr Hennequin’s recipe for revival is to be more open about his company’s
operations, to be “locally relevant”, and to improve the experience of visiting
his 6,400 restaurants. McDonald’s is blamed for making people fat, exploiting
workers, treating animals cruelly, polluting the environment and simply for
being American. Mr Hennequin says he wants to engage in a dialogue with the
public to address these concerns.
D. He introduced “open door” visitor days in each country which became hugely
popular. In Poland alone some 50,000 visitors came to McDonald’s through the
visitors’ programme last year. The Nutrition Information Initiative, launched
last year, put detailed labels on McDonald’s packaging with data on calories,
protein, fat, carbohydrates and salt content. The details are also printed on
tray-liners.
E. Mr Hennequin also wants people to know that “McJobs”, the low-paid menial
jobs at McDonald’s restaurants, are much better than people think. But some of
his efforts have backfired: last year he sparked a controversy with the
introduction of a “McPassport” that allows McDonald’s employees to work anywhere
in the European Union. Politicians accused the firm of a ploy to make cheap
labour from eastern Europe more easily available to McDonald’s managers across
the continent.
F. To stay in touch with local needs and preferences, McDonald’s employs
local bosses as much as possible. A Russian is running McDonald’s in Russia,
though a Serb is in charge of Germany. The group buys mainly from local
suppliers. Four-fifths of its supplies in France come from local farmers, for
example. (Some of the French farmers who campaigned against the company in the
late 1990s subsequently discovered that it was, in fact, buying their produce.)
And it hires celebrities such as Heidi Klum, a German model, as local brand
ambassadors.
G. In his previous job Mr Hennequin established a “design studio” in France
to spruce up his company’s drab restaurants and adapt the interior to local
tastes. The studio is now masterminding improvements everywhere in Europe. He
also set up a “food studio”, where cooks devise new recipes in response to local
trends.
H. Given France’s reputation as the most anti-American country in Europe, it
seems odd that McDonald’s revival in Europe is being led by a Frenchman, using
ideas cooked up in the French market. But France is in fact the company’s most
profitable market after America. The market where McDonald’s is weakest in
Europe is not France, but Britain.
I. “Fixing Britain should be his priority,” says David Palmer, a restaurant
analyst at UBS. Almost two-thirds of the 1,214 McDonald’s restaurants in Britain
are company-owned, compared with 40% in Europe and 15% in America. The company
suffers from the volatility of sales at its own restaurants, but can rely on
steady income from franchisees. So it should sell as many underperforming
outlets as possible, says Mr Palmer.
J. M.Mark Wiltamuth, an analyst at Morgan Stanley, estimates that European
company-owned restaurants’ margins will increase slightly to 16.4% in 2007. This
is still less than in the late 1990s and below America’s 18-19% today. But it is
much better than before Mr Hennequin’s reign. He is already being tipped as the
first European candidate for the group’s top job in Illinois. Nobody would call
that a McJob.

The Guardian
1. Consumers are to be presented with two rival new year advertising
campaigns as the Food Standards Agency goes public in its battle with the
industry over the labelling of unhealthy foods.
2. The Guardian has learned that the FSA will launch a series of 10-second
television adverts in January telling shoppers how to follow a red, amber and
green traffic light labelling system on the front of food packs, which is
designed to tackle Britain’s obesity epidemic.
3. The campaign is a direct response to a concerted attempt by leading food
manufacturers and retailers, including Kellogg’s and Tesco, to derail the
system. The industry fears that traffic lights would demonise entire categories
of foods and could seriously damage the market for those that are fatty, salty
or high in sugar.
4. The UK market for breakfast cereals is worth ￡1.27bn a year and the
manufacturers fear it will be severely dented if red light labels are put on
packaging drawing attention to the fact that the majority are high in salt
and/or sugar.
5. The industry is planning a major marketing campaign for a competing
labelling system which avoids colour-coding in favour of information about the
percentage of "guideline daily amounts" (GDAs) of fat, salt and sugar contained
in their products.
6. The battle for the nation’s diet comes as new rules on television
advertising come into force in January which will bar adverts for unhealthy
foods from commercial breaks during programmes aimed at children. Sources at the
TV regulators are braced for a legal challenge from the industry and have
described the lobbying efforts to block any new ad ban or colour-coded labelling
as "the most ferocious we’ve ever experienced".
7. Ofcom’s chief executive, Ed Richards, said: "We are prepared to face up to
any legal action from the industry, but we very much hope it will not be
necessary." The FSA said it was expecting an onslaught from the industry in
January. Senior FSA officials said the manufacturers’ efforts to undermine its
proposals on labelling could threaten the agency’s credibility.
8. Terrence Collis, FSA director of communications, dismissed claims that the
proposals were not based on science. "We have some of the most respected
scientists in Europe, both within the FSA and in our independent advisory
committees. It is unjustified and nonsensical to attack the FSA’s scientific
reputation and to try to undermine its credibility."
9. The FSA is understood to have briefed its ad agency, United, before
Christmas, and will aim to air ads that are "non-confrontational, humorous and
factual" as a counterweight to industry’s efforts about the same time. The
agency, however, will have a tiny fraction of the budget available to the
industry.
10. Gavin Neath, chairman of Unilever UK and president of the Food and Drink
Federation, has said that the industry has made enormous progress but could not
accept red "stop" signs on its food.
11. Alastair Sykes, chief executive of Nestlé UK, said that under the FSA
proposals all his company’s confectionery and most of its cereals would score a
red. "Are we saying people shouldn’t eat confectionery? We’re driven by
consumers and what they want, and much of what we do has been to make our
products healthier," he said.
12. Chris Wermann, director of communications at Kellogg’s, said: "In
principle we could never accept traffic light labelling."
13. The rival labelling scheme introduced by Kellogg’s, Danone, Unilever,
Nestlé, Kraft and Tesco and now favoured by 21 manufacturers, uses an
industry-devised system based on identifying GDAs of key nutrients. Tesco says
it has tested both traffic lights and GDA labels in its stores and that the
latter increased sales of healthier foods.
14. But the FSA said it could not live with this GDA system alone because it
was "not scientific" or easy for shoppers to understand at a glance.
Questions 1-6
Answer the questions below using NO MORE THAN THREE WORDS from the passage
for each answer.
1. When will instructions be given on reading the color-coded labels?
2. Where can customers find the red light labels?
3. What problem is the FSA trying to handle with the labeling system?
4. Which product sells well but may not be healthy?
5. What information, according to the manufacturers, can be labeled on
products?
6. What can not be advertised during children’s programmes?
