KUNMING, Dec. 11 (Xinhua) -- By moonlight, Ma Yuanqiong, a grassroots AIDS prevention practitioner, and her colleagues slipped into a large community of migrant workers in the city of Jinghong in southwest Yunnan province.As usual, they were greeted tepidly. A dozen sex workers living in the community came to obtain free condoms and brochures on AIDS prevention and quickly dispersed."We visit these women every week. They are familiar with us, but rarely talk about themselves," said Ma, who is in charge of an AIDS prevention program targeting sex workers in Jinghong. The program was initiated by Fuhua International, a local NGO.Sex workers are highly sensitive and vigilant due to safety concerns, since sexual services are illegal in China, Ma said. They have become harder to find since local police started a persistent crackdown on prostitution two years ago and drove many sex workers underground, she said.INACCESSIBILITY IMPEDES EFFORTSJinghong is located in Xishuangbannan Dai autonomous prefecture. Bordering Laos and Myanmar, it's a famous tourist city where the underground sex industry thrives.The AIDS prevention program, which began in 2006, is aimed at improving sex workers' awareness of the epidemic -- which is primarily sexually transmitted -- and prompting them to change risky behavior.In the beginning, program workers quickly realized they faced a significant challenge. "We were often rejected, or even threatened when trying to get in touch with the sex workers at first," Ma said.But the practitioners persisted, approaching nonjudgmentally and treating them as friends, and eventually their efforts began to pay off.During the past five years, the program has provided free condoms and AIDS consulting services to more than 400 sex workers aged 14 to 58 and from many parts of the country, according to Ma.The program has even helped several sex workers give up the business and pursue legitimate careers.However, the organization currently only keeps in touch with about 100 sex workers and has found it more difficult to reach more.The police crackdown has made the sex workers, especially low-paid street hookers, more mobile and less visible, and Ma pointed out that low-paid sex workers are in greater need for outreach as they are more vulnerable to HIV infection than their their higher-paid counterparts."Low-level sex workers are at a heightened risk, as they and their clients, mainly migrant workers and the elderly, all have insufficient knowledge of the disease," she said.According to statistics provided by the provincial disease control and prevention center (CDC) of Yunnan, about 1.6 percent of sex workers in Yunnan have contracted HIV, while the ratio among the low-level group is 3 percent.By the end of October, Yunnan reported 93,567 HIV carriers and AIDS patients, the most among all provinces, autonomous regions and municipalities."We conducted a survey in Jinghong and neighboring Menghai County at the end of 2008 and found that low-level sex workers almost never used condoms then," said Kang Jun, head of the HIV/AIDS prevention and treatment office in Xishuangbanna.The survey also found that the low-level sex workers only charged about 20 yuan (3.2 U.S. dollars) for each service, and every day they received 16 clients on average, according to Kang.Ahead of the police crackdown, Kang and his colleagues had provided HIV testing services for more than 30 low-level sex workers, and the results showed that two of them had been infected by the virus."The testing work was forced to halt as the crackdown began soon and we could hardly find them," Kang said.The good news, he said, was that the local CDC will launch a four-year investigation on sex workers in Xishuangbanna next January as part of a massive state-funded research project.

UNITED NATIONS, Oct. 28 (Xinhua) -- China's progress in meeting a development goal on children's health can serve as an inspiration to other countries working towards the same objective, Dr. Renee Van de Weerdt, chief of maternal, newborn and child health at the UN Children's Fund (UNICEF) told Xinhua in an interview Friday.Van de Weerdt said that "the example of China is very encouraging because it means it can be done, even in a very big country with a very big population."China is on track to meet the fourth Millennium Development Goal (MDG), one of the eight development targets that the international community has pledged to meet by 2015. MDG 4 requires that each country reduce its rate of mortality for children under age five to two-thirds of what it was in 1990.According to Van de Weerdt, most deaths of children under five take place in the first month of life. After the first month, the most prevalent causes of death are pneumonia and diarrhea.ACHIEVING THE GOAL WORLDWIDEThe international community has been doing "relatively well" in working towards achieving MDG 4, Van de Weerdt said.The UN Interagency Group for Child Mortality Estimation (IGME) stated in their 2011 Report on Levels and Trends in Child Mortality that the number of under-five deaths worldwide has dropped from more than 12 million in 1990 to 7.6 million in 2010."We really continue to see progress," Van de Weerdt said. "The number of children that die every year continues to drop so we are really pleased to see that progress. Unfortunately, the progress isn't sufficient to really be able to say that if we continue at this pace we would achieve MDG 4 by 2015."Some regions, according to Van de Weerdt, like Latin America and parts of Asia are making more headway towards the goal than others that are currently lagging behind.

JERUSALEM, Jan. 12 (Xinhua) -- An Israeli company has developed a system that scans the brain and provides a three dimensional image of the nerve cell connectivity to treat brain diseases like Alzheimer's or HDHD.The firm ElMindA trademarked a non-invasive system, the BNA ( Brain Network Activation), that helps doctors visualize the connectivity between nerve cells and synchronization that can even measure the severity of the patients condition from one day to another, the Israel21c news site reported on ThursdayBy creating a three-dimensional image of the brain while asking the patients to repeat an activity several times, BNA developers hope this system will become a regular way of diagnosing brain illnesses."Our vision is that every psychiatrist and neurologist in the world will routinely send every patient for BNA tests," said Dr. Eli Zangvil, ElMindA's strategic advisor for business development. "Our test would add information and aid in diagnostics in a way no other existing technology can do," he added.BNA could help doctors find out exactly at what stage of the disease patients and prescribe the exact medication for them."To do that, we must collect a lot of data," Zangvil said. "To say this person has a certain disease or condition, I have to be able to compare their pattern to a normal brain pattern of a person of the same age and gender." he said.Researchers hope to gather the amount of data they need to obtain FDA approval in the U.S. by the end of 2012, and start marketing it to hospitals by 2013.

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.

BEIJING, Jan. 21 (Xinhua) -- A locomotive producer in central China's Hunan province on Friday rolled out a low-cost magnetically levitated (maglev) train that is more environmental-friendly than conventional ones.The three-carriage train is designed to run at a maximum speed of 100 km per hour and carry 600 passengers, said Xu Zongxiang, general manager of Zhuzhou Electric Locomotive Co. Ltd. of China South Locomotive and Rolling Stock Corporation (CSR). Xu said the new train was much quieter than conventional ones. While a conventional train moves forward by using friction between its wheels and the railway tracks, the maglev train replaces wheels by electromagnets and levitates on the guideway. According to Xu, his company's has minimized the risk of the new maglev train derailing or overturning. "It's ideal for mass transportation, as it is quiet and environmental-friendly. Its manufacturing cost is about 75 percent of a conventional light-rail train," said Xu. The maglev train has a minimum turning radius of 50 meters and can easily run in residential communities or on hilly slopes. "It's an ideal public transport option for Chinese cities and major tourist destinations," said Xu. Railway transport specialist Liu Youmei, also an academician with Chinese Academy of Engineering, said the new train is green, economical and safe. "It can be used for public transport in populous areas and at scenic spots with fragile environments." Liu said China is one of a few countries that have applied maglev technology. Beijing is building a maglev route, the Daitai line (S1), which starts at its IT center in Haidian district, passes through Shijingshan district, and ends in Mentougou district on its western outskirts. The line will be operational next year.The eastern metropolitan of Shanghai runs the world's first commercial maglev system on a 30-km stretch between the downtown business district and Pudong airport. The German-made maglev went into operation on Dec. 31, 2002.
