BEIJING, Otc. 26 (Xinhuanet) -- The more coffee people consume, the less likely they develop the most common form of skin cancer, a new study suggests, according to media reports Tuesday."Our study indicates that coffee consumption may be an important option to help prevent basal cell carcinoma," stated Fengju Song, lead researcher of the study and a postdoctoral fellow in the department of dermatology at Brigham and Women's Hospital and Harvard Medical School in Boston.Basal cell carcinoma (BCC) is reported to be a slow-growing form of skin cancer that accounts for 75 percent of all skin cancers. It is the most common type of skin cancer, with nearly one million new cases diagnosed each year in the United States.Although BCC is hardly fatal, if ignored, there may be consequences of treatment, including disfigurement, according to a USA Today report.The US researchers found that women who drank over three cups of coffee a day were 20 percent less likely to develop BCC, whereas the risk of having BCC for men who consumed more than three cups per day lowered 9 percent.To get the findings, the researchers analysed data from almost113,000 people between1984-2008 and over 23,000 were diagnosed with BCC.The researchers agreed that caffeinated coffee was associated with BCC risk reduction, but decaffeinated coffee did not have such effect.According to a Fox News report, besides cutting the risk of skin cancer, coffee consumption has also been found to lower the risk of breast cancer and prostate cancer and cancer overall."To the best of our knowledge, coffee consumption is a healthy habit," said Fengju Song, cited by the Fox News.The findings were presented Monday at the American Association for Cancer Research International Conference in Boston and not yet published in a scientific journal.

WASHINGTON, Nov. 7 (Xinhua) -- U.S. researchers have demonstrated for the first time that the brain is a key player in regulating glucose (sugar) metabolism in humans.The findings, published Monday in the online edition of the Journal of Clinical Investigation, suggest that drugs targeting the brain and central nervous system could be a novel approach to treating diabetes."The brain is the body's only organ that needs a constant supply of glucose to survive, so it makes sense that it would have some say over how much glucose is produced," said study leader Meredith Hawkins, professor of medicine and director of the Global Diabetes Initiative at Yeshiva University, in a statement. "This role for the brain was demonstrated in earlier studies in rodents, but there was considerable controversy over whether the results could be applied to humans. We hope this study helps to settle the matter."In an earlier study in rodents, researchers showed that activation of potassium channels in the brain's hypothalamus sends signals to the liver that dampen its production of glucose. Those findings, published in Nature in 2005, challenged the conventional thinking that blood sugar production by the liver (the body's glucose factory) is regulated only by the pancreas (which makes insulin to metabolize glucose). But carefully performed studies on dogs, conducted at Vanderbilt University, failed to replicate the results, suggesting the Einstein findings in rodents might not be relevant to higher mammals, including humans.The current study, involving people, was aimed at resolving this controversy. Ten nondiabetic subjects were given oral diazoxide, a drug that activates potassium channels in the hypothalamus. (The drug is not used to treat diabetes.) Hormone secretion by the pancreas was controlled to ensure that any change in sugar production would only have occurred through the drug's effect on the brain. After the researchers administered the drug, blood tests revealed that patients' livers were producing significantly less glucose than before.Hawkins and her team then repeated this in rats, again giving diazoxide orally, achieving similar results. They confirmed that sufficient amounts of diazoxide crossed the blood-brain barrier to affect potassium channels in the hypothalamus. Additional experiments confirmed that diazoxide was working through the brain. Specifically, the researchers were able to completely block the effects of diazoxide by infusing a specific potassium channel blocker directly into the brain."This study confirms that the brain plays a significant role in regulating glucose production by the liver," said lead author Preeti Kishore, assistant professor of medicine. "We are now investigating whether this 'brain-to-liver' pathway is impaired in people with diabetes. If so, we may be able to restore normal glucose regulation by targeting potassium channels in the brain."

BEIJING, Dec. 9 (Xinhua) -- Beijing has seen a declining trend in newly built ordinary apartments in the past 11 months of this year, said a report released by the Beijing Real Estate Association on Friday.That average price of 13,914 yuan (about 2,194.23 U.S. dollars) per square meter from January to November went down 6.3 percent from the yearly average housing price of 14,847 yuan per square meter in 2010, also the target set by the municipal government in attempting to control soaring house prices, said the report.It is expected that the real-estate market in Beijing will maintain the gradually declining trend. And the target of "a stable yearly price with a slight decline" will be smoothly reached, said Chen Zhi, secretary-general of the association.In November, first-time home buyers took up about 90 percent of housing consumers for the ninth month in a row, which means the government's measures to crowd out investing or speculative buying and meet the demands of conventional buyers are working, the report said.This year the government has repeatedly stressed its efforts to contain the runaway property market, through measures including tighter monetary policies, higher down payments, a ban on third-home purchases, price control targets and a trial property tax.

BEIJING, Sept. 30 (Xinhuanet) -- Tobacco companies concealed the knowledge of radioactive substance in cigarettes from public for over four decades, a new study revealed.The revelation was made by a research team from the University of California, Los Angeles, published on Thursday in the online edition of the U.S. medical journal Nicotine and Tobacco Research.The researchers analyzed 27 timeworn documents and discovered that tobacco companies had knew the existence of polonium-210, a hazardous radioactive substance, in the tobacco since 1959.The companies studied polonium-210 throughout the 1960s, and concealed their findings about the carcinogenic potential of the radioactive substance.Hrayr Karagueuzian, the study's lead author, said the tobacco companies' deception surprised him.According to the revelation, the companies had knew the "cancerous growths" in the lungs of smokers, and even calculated how much radiation a regular smoker would inhale over 20 years.Karagueuzian and his team conducted again the study recorded in the tobacco documents and found that the radiation in cigarettes would cause up to 138 deaths for every 1,000 smokers over a period of 25 years.However, tobacco manufacturer denied that they had concealed the facts from the public.David Sutton, spokesman of Philip Morris, the largest U.S. tobacco company, said the polonium-210 was a "naturally occurring element in the air" and had been widely discussed by the public health community for years.

BEIJING, Oct. 13 (Xinhuanet) -- Himalayas may be one of the most potential regions to provide solar power in future, according to a new research by Japanese scientists quoted by media reports Thursday. Deserts are usually regarded as the hotbeds for capturing solar power, but some of the loftiest and coldest regions can receive more energy from the sun than some deserts, said Takashi Oozeki and Yutaka Genchi, authors of the research published in Environmental Science and Technology. To set up solar cells on Himalayas would be challenging. Transmission losses and snowfall should be taken into consideration, said the researchers with the National Institute of Industrial Science and Technology in Japan. Still, the Himalayan region is attractive, because there are large energy demands in the countries nearby."It is near regions with large future energy demands such as China and India," they said.Other cold regions that can receive solar power include Andes of South America and Antarctica, according to the study.
