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.

WASHINGTON, Jan. 2 (Xinhua) -- A hormone derived from visceral fat called adiponectin may play a role as a risk factor for development of all-cause dementia and Alzheimer's disease (AD) in women, according to a study published on Monday in online issue of the Archives of Neurology.Thomas van Himbergen, from Human Nutrition Research Center on Aging at Tufts University, and colleagues measured levels of glucose, insulin, and glycated albumin, as well as C reactive protein, lipoprotein associated phospholipase A2, and adiponectin in the plasma of patients at the 19th biennial examination (1985 -- 1988) of the Framingham Heart Study.The 840 patients (541 women, median age of 76 years) were followed-up for an average of 13 years and evaluated for signs of the development of AD and all-cause dementia. During that time, 159 patients developed dementia, including 125 cases of AD. After adjustment for other dementia risk factors (age, low plasma docosahexaenoic acid, weight change) only adiponectin in women was associated with an increased risk of all-cause dementia and AD."It is well established that insulin signaling is dysfunctional in the brains of patients with AD, and since adiponectin enhances insulin sensitivity, one would also expect beneficial actions protecting against cognitive decline," the authors write. "Our data, however, indicate that elevated adiponectin level was associated with an increased risk of dementia and AD in women."

SAN FRANCISCO, Nov. 17 (Xinhua) -- Online retail giant Amazon is working on a smartphone scheduled to be released in the fourth quarter of 2012, U.S. media reported Thursday.A note from Citigroup analyst Mark Mahaney obtained by technology news site All Things Digital said that based on the supply chain checks in Asia, Amazon is believed to launch a smartphone in the fourth quarter of 2012.According to the note, Amazon is working with manufacturer Foxconn and the device will run Texas Instruments' OMAP 4 processor. The Kindle Fire, the latest tablet introduced by the e- commerce giant, also uses OMAP processor.The analyst said the smartphone will cost Amazon between 150 and 170 U.S. dollars to build and the company could sell the handset at or near its cost rather than a 30 percent gross margin like many other smartphone manufacturers usually do.The move is expected to further intensify Amazon's rivalry with Apple and Google after the e-commerce giant had made moves on some booming businesses like tablet computer and cloud-computing service.
