WASHINGTON, Nov. 10 (Xinhua) -- The U.S. Food and Drug Administration (FDA) has sent warning letters to more than 1,200 retailers, the majority of which respond to violations relating to selling tobacco to minors, as part of its ongoing effort to reduce tobacco use among children, the agency announced Thursday in a statement.The FDA said that while most retail establishments have been found to be in compliance with the law, some retailers are still selling cigarettes and smokeless tobacco to minors. Warning letters may be followed by civil money penalties if retailers continue to violate the law."It should worry every parent that 20 percent of U.S. high school students smoke cigarettes," said FDA Commissioner Margaret Hamburg in a statement. "President Obama and the FDA are committed to preventing children from smoking. For many young people, that first cigarette or use of smokeless tobacco will lead to a lifetime of addiction, and for many, serious disease. More than 80 percent of adult smokers begin smoking before 18 years of age. Retailers are vital partners in the FDA's efforts to prevent tobacco use among kids."Obama signed the Family Smoking Prevention and Tobacco Control Act that gives the FDA authority to regulate tobacco products to prevent use by minors and reduce the impact on public health. One of the law's provisions permits the FDA to contract with states and territories to conduct compliance check inspections of tobacco retailers. In 2011, the FDA awarded compliance contracts totaling more than 24 million U.S. dollars to 38 states.The FDA also began inspecting U.S. tobacco product manufacturers in October 2011. This is the first time tobacco product manufacturing facilities have ever been inspected by a federal public health agency.

BEIJING, Nov. 22 (Xinhuanet) -- Global AIDS deaths and new HIV infections have each dropped 21 percent since the peak of the AIDS pandemic in 1997, according to a UN report released Monday.One major factor responsible for the result is that life-saving HIV treatments have become more popular and got to 1.35 million more people in 2010 than in 2009.In middle-income and underdeveloped nations, these treatments have saved 2.5 million lives since 1995."We have seen a massive scale-up in access to HIV treatment, which has had a dramatic effect on the lives of people everywhere," said Michel Sidibe, executive director of the U.N. AIDS program.However, 53 percent of people who need HIV/AIDS treatments -- about 7.6 million people -- cannot get them, which accounted for 1.8 million AIDS deaths in 2010.There are now 34 million people living with HIV. And just in last year there were 2.7 million new infections.The decline in deaths and new infections means the AIDS pandemic is at a turning point, the UNAIDS report argues, adding smart investment can save millions of future deaths.

BEIJING, Oct. 27 (Xinhuanet) -- A new study shows that it's not simply a lack of willpower that explains weight regain but hormones keep one insisting on eating, a persistent biological urge. As any dieter knows, it's hard to keep weight off. Weight regain is a familiar problem for dieters. The research appears in Thursday's issue of the New England Journal of Medicine. To study what drives it, Proietto and his colleagues enrolled 50 overweight or obese patients in Australia in a 10-week diet program. On average, the participants lost almost 30 pounds in the 10 weeks - faster than the standard advice of losing a pound or two per week. Even so, they gained an average of 12 pounds back over the next year. The scientists checked the blood levels of nine hormones known to influence appetite - and found that even a year after the end of the weight-loss program, six of the hormones were still out of whack. People who regain weight should not be harsh on themselves, as eating is our most basic instinct, study author Joseph Proietto of the University of Melbourne in Australia said. It's better not to gain weight than to try to lose it.
