1、Lower Body Fat Means Better Performance
These days, fashion models and pop stars are not the only people who have to watch their waistline. Football players who miss a few kicks and let their belly hanging out a little too much are likely to be attacked by rabid fans or even the president of a country.
The latest football star to draw the attention of the "fat police" is Barcelona's Ronaldinho, 26. Last Friday, a Spanish sports daily published two photos of the Brazilian star without his shirt. One was taken in November 2003; the other was taken this month. In the most recent one, the star's waistline seems to have a little extra padding.
Another Spanish sports daily published similar before-and-aider photos and argued that the star has "lost his explosiveness and velocity" and is "worn out". The cause, according to the news paper, is his poor physical fitness.
However, the player's coach, Frank Rijkaard, insists that he's satisfied with Ronaldinho's form and fitness. And after Barcelona's victory over Athletic Bibao on Sunday, Ronaldinho challenged photographers to take pictures of him when he took off his shirt.
"I don't have anything to hide," he said.
Fellow Brazilian ronaldo, 30, of Real Madrid, faced similar criticism before the 2006 World Cup. But the criticism didn't come from a bunch of sports reporters: It came from the president of Brazil.
"So, what is it?" Brazil's President Luiz Inacio Lula da Silva asked the national soccer team's coach in his office last June, according to the Associated Press. "Is he [ronaldo]fat or not?"
"He is very strong, president," Carlos Alberto Parreira reportedly said at the time. "He is not that boy anymore. His body type has changed. "
The game of footfall demands that players put as much emphasis on fitness as they can do on dribbling, passing or shooting.
During a proper training regimen, football players normally follow a load-fatigue-recovery pattern. They push their body toward a higher mark of fitness and experience a slight and brief drop in performance. Then they begin the recovery process, which will ideally carry their performance to an even higher plane.
However, sometimes non-physical factors can influence a player's poor fitness. In Ronaldinho's case, for instance, people, often unnamed, have blamed everything from the pressure of contract negotiations to personal problems and too many advertising commitments.
According to CalosAlber to Parreira, ronaldo's body shape has changed.

2、Smoking Can Increase Depressive Symptoms in Teens
While some teenagers may puff on cigarettes to "self-medicate" against the blues, scientists at the University of Toronto and the University of Montreal have found that smoking may actually increasedepressive symptoms in some teens.
"This observational study is one of the few to examine the perceived emotional benefits of smoking among teens," says lead researcher Michael Chaiton, a research associate at the Ontario Tobacco Research Unit of the University of Toronto." Although cigarettes may appear to have self-medicating effects or to improve mood, in the long term we found that teens who started to smoke reported higher depressive symptoms. "
As part of the study, some 662 high school teenagers completed up to 20 questionnaires about their use of cigarettes to affect mood. Secondary schools were selected to provide a mix of French and English participants, urban and rural schools, and schools located in high, moderate and low socioeconomic neighborhoods. Participants were divided into three groups: never smokers; smokers who did not use cigarettes to self-medicate, improve mood or physical state; smokers who used cigarettes to self-medicate. Depressive symptoms were measured using a scale that asked how felt too fired to do things: had trouble going to sleep or staying asleep; felt unhappy, sad, or depressed; felt hopeless about the future; felt vexed, antsy or tense; and worried too much about things.
"Smokers who used cigarettes as mood improvers had higher risks of elevated depressive symptoms than teens who had never smoked," says co-researcher Jennifer O'Loughlin, a professor at the University of Montreal Department of Social and Preventive Medicine. "Our study found that teen smokers who reported emotional benefits from smoking are at higher risk of developing depressive symptoms."
The association between depression and smoking exists ____ among teens that use cigarettes to feel better. "It's important to emphasize that depressive symptom scores were higher among teenagers who reported emotional benefits from smoking after they began to smoke," says Dr. Chaiton.

3、Human Heart Can Make New Cells
Solving a longstanding (为时甚久的) mystery, scientists have found that the human heart continues to generate new cardiac(心脏的 ) cells throughout the life span, although the rate of new cell production slows with age.
The finding, published in the April 3 issue of Science, could open a new path for the treatment of heart diseases such as heart failure and heart attack, experts say.
"We find that the beating cells in the heart, cardiomyocytes (心肌细胞), are renewed," said lead researcher Dr. Jonas Frisen, a professor of stem cell research at the Karolinska Institute in Stockholm, Sweden. "It has previously not been known whether we were limited to the cardiomyocytes we are born with or if they could be renewed," he said.
The process of renewing these cells changes over time, Frisen added. In a 20 - year - old, about I percent of cardiomyocytes are exchanged each year, but the turnover (更替) rate decreases with age to only 0.45 percent by age 75.
"If we can understand how the generation of new cardiomyocytes is regulated, it may be potentially possible to develop pharmaceuticals (药物) that promote this process to stimulate regeneration after, for example, a heart attack," Frisen said.
That could lead to treatment that helps restore damaged hearts.
"A lot of people suffer from chronic heart failure," noted co - author Dr. Ratan Bhardwaj, also from the Karolinska Institute. "Chronic heart failure arises from heart cells dying," he said.
With this finding, scientists are "opening the door to potential therapies (疗法) to having ourselves heal ourselves." Bhardwaj said. "Maybe one could devise a pharmaceutical agent that would make heart cells make new and more cells to overcome the problem they are facing. "
But barriers remain. According to Bhardwaj, scientists do not yet know how to increase heart cell production to a rate that would replace cells faster than they are dying off, especially in older patients with heart failure. In addition, the number of new cells the heart produces was estimated using healthy hearts-whether the rate of cell turnover in diseased hearts is the same remains unknown.
The finding could prove to be useful to ______.【单选题】

A.the analysis of cardiac cells

B.the prevention of chronic diseases

C.the treatment of heart diseases

D.the study of longstanding mysteries

5、Breast Cancer Deaths Record Low
The number of women dying from breast cancer has fallen to a record low by dropping under 12,000 a year for the first time since records began.
The Cancer Research UK data showed that 11,990 women died in the UK in 2007.
The previous lowest figure had been recorded in 1971-the year records began after which it rose steadily year by year until the late 1980s.
Professor Peter Johnson, Cancer Research UK's chief clinician said, "It's incredibly encouraging to see fewer women dying from breast cancer now than at any time in the last 40 years, despite breast cancer being diagnosed more often. "
Research has played a crucial role in this progress leading to improved treatments and better management for women with the disease.
"The introduction of the NHS (国民保健制度) breast screening program has also contributed as women are more likely to survive the earlier cancer is diagnosed. "
Breast cancer is now the most common cancer in the UK with 45,500 women every year diagnosed with the disease, a 50% rise in 25 years.
The number of deaths peaked in 1989, when 15,625 women died. It then fell by between 200 and 400 deaths each year until 2004.
There was a slight rise in 2005 and then two years of falls.
Dr Sarah Cant, policy manager at Breakthrough Breast Cancer, said, "It is great news that fewer women are dying from breast cancer and highlights the impact of improved treatments, breast screening and awareness of the disease. " .
"However, this is still too many women and incidence of the disease is increasing year by year."
The rising rate of breast cancer diagnosis has been put down to a variety of factors including obesity（肥胖） and alcohol consumption.
