BEIJING, Sept. 29 (Xinhuanet) -- Even a slightly high blood pressure is considered dangerous to largely increase the stroke risk, a new study found.The finding was published Wednesday on the online edition of U.S. medical journal Neurology.In the study, researchers found people who have pre-hypertension, whose blood pressure measured between normal and high, are 55 percent more likely to suffer a stroke compared with normal people.The study involved data from 12 previous studies on blood pressure and stroke occurrence of some 500,000 adults.About one in three U.S. adults suffer from pre-hypertension, which is defined at a systolic blood pressure between 120 and 139 or a diastolic blood pressure between 80 and 89, according to the U.S. Joint National Committee on Prevention, Detection, Evaluation and Treatment of High Blood Pressure."People who do fall into the higher range of pre-hypertension should modify their lifestyle as much as possible," suggested Dr. Bruce Ovbiagele, director of the Olive View-UCLA Stroke Program and leading author of the study.Stroke is the number three cause of death, killing more than 130,000 in the U.S. a year, according to a CBS report.

BEIJING, Oct. 20 (Xinhuanet) -- British scientists used bacteria and DNA to build basic components for digital devices in a new research, according to media reports, suggesting biological computers come closer to reality.Digital devices are based on logic gates, fundamental building blocks in silicon circuitry, said Professor Richard Kitney, leading researcher of the research published in the journal Nature Communications, "Without them, we could not process digital information."According to Science Daily, Professor Kitney and his colleagues from the Imperial College London replicated the building blocks using bacteria and DNA, forming biological logic gates, which paved the way for building more complex biological processors in the future.The researchers hoped biological computers can be applied to monitoring human health in the future.They believed that small biological processors, inserted in human bodies, could roam inside the bodies, monitor the health, and correct any problems they found.These biological logic gates are the most advanced created by scientists. But there is still a long way to go to apply them in reality, said Professor Kitney.

BEIJING, Oct. 2 (Xinhua) -- Chinese archeologists have found evidence indicating that the mysterious ancient city of Loulan (Kroraina) once had highly-developed agricultural systems.Scientists from the Institute of Geology and Geophysics under the Chinese Academy of Sciences conducted remote sensing procedures, field investigations and sample testing in the area and found that there were once large tracts of farmlands in Loulan.The farmland featured regular and straight circumferences stretching for 200 to 1,000 meters as well as irrigation ditches running throughout, said Qin Xiaoguang, a member of the research team.Moreover, researchers found grain particles in the area's ground surface, which are very likely to be remains of crop plants, Qin said.These findings show that irrigation farming had been practiced in Loulan for at least 100 years, Qin said.Qin said they also found canal remains measuring 10 to 20 meters wide and 1.6 meters deep in the Loulan relics, indicating that the city, which is suspected of perishing in drought, was once rich in water resources.The ancient city was a pivotal stop along the famous Silk Road, but mysteriously disappeared around the third century AD.Previous historical records suggested that Loulan's economy was sustained by widespread agricultural activity, but no remains or other evidence had been found before the most recent discoveries.

WASHINGTON, Nov. 25 (Xinhua) -- In the United States, the AIDS epidemic has plateaued, but it is still at "unacceptable high" level, a U.S. expert said ahead of the World AIDS Day."The situation is stable in the United States, stable in an unacceptable high level for at least 10 years and has not gone down. It's still a serious problem," Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases (NIAID), told Xinhua in an exclusive interview.According to Fauci, there are about 1.1 million people infected with HIV in the U.S., of which about 20 percent do not know they are infected. Those are the ones that more likely will infect other people. Since the world's first AIDS case was reported 30 years ago, the U.S. has seen close to 600,000 AIDS-related death. And among the 65,000 new infections each year in the U.S, about 50 percent are African Americans. In the United States, about 12 percent of the population is African American."Our new approach to prevention is to try and get access at community level, to people at most risk, to seek out to voluntarily test, to link them to care, and to automatically get them treatment," said Fauci. "When you get someone on treatment, it is extremely unlikely that they will infect their sexual partner."Fauci thought the international community's battle against the HIV/AIDS has gotten better over the last 30 years.Early on, when the disease was inaccurately thought to be a disease of developed world. There was a denial in many countries in Asia, in Southern Africa, South America and Caribbean, that this will turn out to be an extraordinary problem in those countries. As the years went by, it was clear that it was not a disease of gay men in the United States and the developed world. It was a disease mostly in the developing world when 90 percent of new infections occur in low- and middle-income countries and 67 percent of the cases are in Southern Africa."The response of the global community first was denial and not full appreciation of the potential impact of the pandemic. As the years have gone by, the response has been better and better," said Fauci, an immunologist that has made substantial contributions to research in the areas of AIDS and other immunodeficiencies, both as a scientist and as the head of NIAID.The advance in the arena of therapy with drugs has been " spectacular" and "very impressive", he said.In the early 1980 before there were any drugs, the median survival period of people in the United States who was infected with HIV, was about six to eight months. "Today in 2010, if someone was newly infected with HIV and he's 20-25 years old, and you put them on therapy, you can predict mathematically that they will live additional 50 years," said Fauci.Over the last couple of years, there has been "significant but slow" advances with vaccines against HIV. For example, there was a trial that was conducted in Thailand in which there was a modest degree of efficacy, about 31 percent of protection."That's not enough to have a vaccine available for widespread use but give us some important clues into what next generation of vaccines would be," said Fauci.As to the "three zeros" target adopted by the United Nations this year, Fauci said that it's "aspirational but not gonna be easy.""It is good to set very high goals for the future. I don't think that we realistically are gonna get to zero new infections, zero new discrimination, zero (AIDS-related) death in the next few years," said Fauci. "I think it will take several years to get there. I believe that if more countries and the international community are engaged to play a role in trying to stop HIV, to prevent and treat and care for HIV-infected individuals, that we will automatically achieve that objective."

BALI, Indonesia, Nov. 19 (Xinhua) -- Chinese Premier Wen Jiabao said on Saturday that an immediate task for East Asian nations in the face of the global financial crisis was to maintain continuous, rapid development of the region's economy.Addressing the 6th East Asia Summit, Wen said East Asian nations should provide momentum for the world economy's robust, sustainable and balanced development."We should continue to strengthen cooperation and the summit should play a strategic role in this regard," he said.Wen put forward a five-point proposal for boosting the regional economy:First, coping with the international economic and financial crisis should continue to be regarded as a priority, he said.East Asian nations should implement appropriate fiscal and monetary policies in accordance with their national conditions, shore up market confidence, and enhance coordination in the macro-economic policy and financial cooperation.Second, Wen said the region should earnestly carry out and improve agreed free trade arrangements, steadily advance the building of new free trade areas, and further open markets.The Chinese premier called on East Asian nations to counter protectionism and properly handle international trade frictions.Third, the region should encourage expansion of investment and increase investor confidence, he said.It should boost the inner drive for its development through such ways as industrial transfer and regional interconnection, Wen said.Fourth, he called for prioritizing sustainable development as a long-term cooperative goal, stronger cooperation in key fields, help for East Asian countries to transform their economic development model, and intensified cooperation in such areas as energy-saving, environmental protection, education and disaster control, so as to enhance development potential.His final point urged overcoming challenges brought by non-traditional security threats to create a better environment for development, and strengthening cooperation in the fields of information exchange, capacity building and emergency response.Wen said that, as a strategic forum, the EAS facilitated mutual understanding and cooperation between East Asian nations."Under the new situation, we should continue to regard the Association of Southeast Asian Nations (ASEAN) as the dominant power of cooperation at the summit and make efforts to seek and expand interest junctions," he said.China was willing to work with all sides to make the summit more fruitful and benefit more countries and peoples, the Chinese premier said.Echoing Wen's remarks, participants at the summit said under the current international political and economic situation, East Asian cooperation should continue to wield the influence of ASEAN domination and the existing mechanism to intensify mutual support and coordination, and deepen cooperation in the fields of economy and trade, finance, food security, energy security and disaster relief.
