NEW YORK, Dec. 1 (Xinhua) -- New York City Mayor Michael Bloomberg announced on Thursday a new recommendation that doctors offer every person with an HIV diagnosis antiretroviral treatment to help them live longer and prevent transmission.This marks a change from the current practice that treatment only be offered to those who show signs of damage to their immune systems, said the mayor during the annual World AIDS Day commemorative ceremony at Gracie Mansion. "Over the past ten years HIV diagnoses and deaths in New York City have seen a dramatic decline," said Mayor Bloomberg. "Steady progress in our fight against HIV has turned what used to be a death sentence into a disease that can be prevented and, with antiretroviral therapy, managed.The annual death toll from HIV in the city is down by more than a third: 933 deaths in 2009Despite this progress, however, more than 110,000 people in New York City are infected with HIV, more than in any other U.S. city and about 75 percent of all cases in the New York State.Figures from the New York City Health and Hospitals Corporation (HHC) showed that HHC has tested more than one million New Yorkers for HIV since 2005 when the public hospitals and health centers began offering HIV screening as a routine part of medical care for patients aged 13 to 64.

SAN FRANCISCO, Nov. 28 (Xinhua) -- Amazon.com on Monday announced that this past Black Friday was the best ever for its Kindle products with consumers buying four times as many Kindle e- readers and tablets as they did last year.According to the online retail giant, its newly launched tablet Kindle Fire was the bestselling product across all of Amazon.com on Black Friday, the day after Thanksgiving, which falls on Nov. 25 this year, when major retailers in the United States traditionally offer big discounts.Kindle Fire is Amazon's answer to Apple's popular iPad. Priced at 199 U.S. dollars, the Amazon product is much cheaper than iPad which starts from 499 dollars.Survey results by research firm ChangeWave Research released days before Black Friday indicated that Amazon is poised to become the No. 2 player in the tablet computer market behind Apple, due to strong demand for Kindle Fire.Amazon said Black Friday sales also showed that a lot of customers were buying multiple Kindles, one for themselves and others as gifts.The trend is expected to continue through this holiday shopping season, Amazon's vice president of Kindle products Dave Limp said in a statement.

YAGNON, Oct. 23 (Xinhua) -- Myanmar has launched anti-dengue high fever campaign in seven townships in Yangon simultaneously as a prevention measure against the disease, according to the Health Department Sunday.The campaign was carried out in the weekend in collaboration with health department staff and members of social organizations.Dengue preventive and control measures were occasionally launched in schools and wards in Myanmar with the aid of World Health Organization, U.N. Children Fund, three Disease Fund, Global Fund and Japan International Cooperation Agency.According to statistics, a total of 181 people died of dengue fever in Myanmar's Yangon region in the past five years alone, out of 19,000 such cases occurring in the region during the half decade.According to earlier report, the number of people infected with dengue fever in the whole country in 2009 amounted to 3,129 with 37 deaths registered.However, according to the Yangon City Development Committee, the city saw less dengue fever occurrence in 2010 with death rate reducing to one percent in the year from over six percent in 1970.Meanwhile, the Myanmar health authorities are stepping up preventive measures against dengue fever in this sensitive rainy season by extending injection to people.The authorities are also introducing medicine with better effect, combating larva, giving education talks on the prevention and control especially in markets.Dengue fever mostly infected under-15 children, especially those between three and nine years old, but now such disease had also been found among some adult people, the authorities said, warning that dengue fever occurs regardless of age and season.Myanmar, along with Indonesia and Thailand, suffers dengue outbreak most in Southeast Asia region that makes up 52 percent of the dengue-prone areas in the world.

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, Oct. 13 (Xinhuanet) -- Tyrannosaurus rex dinosaur, the giant prehistoric predator, was even bigger and heavier than it was estimated previously, a new study found.The finding was contained in a study published Wednesday in the scientific journal PLoS ONE.Using three-dimension scanning and computer modeling, researchers analyzed five skeleton fossils of T. rex dinosaur, including "Sue", the largest and most complete T. rex specimen ever found.The analysis tipped the scale of "Sue" at 9 ton, some 30 percent more than it was expected."At their fastest, in their teenage years, they were putting on 11 pounds or 5 kilograms a day," said John Hutchinson of the Royal Veterinary College in London, who co-led the study.The larger body mass indicated the better agility and the stronger lower-leg muscles of the ancient monster, said the researcher."Sue" could have a top speed of about 10-25 miles per hour when it ran on the Great Plains of North America 67 million years ago, Hutchinson suggested.
