BEIJING, June 27 (Xinhuanet) -- A "lean gene" that helps people keep slim was found closely related to diabetes and heart disease, according to a study pulished in Nature Genetics journal on Sunday.The scientists from Britain’s Medical Research Council Epidemiology Unit conducted the study.After comparing the genetic codes of more than 75,000 people, a gene called IRS1 was spotted as the decisive factor to lower the fat level in human body.But in further study, IRS1 was found putting people to a 20 percent higher risk of developing heart disease and type-2 diabetes.The study warned that people who appear slim and fit might be also at risk.But scientists suggest that the study results did not change the general message for most people."While this study pointed to genes as one factor in determining the risk of developing these conditions, it was important to remember that lifestyle factors like diet, exercise, cutting out smoking and maintaining a healthy weight also play a vital role in reducing the risk," said Ruth Loos, who led the study.

GENEVA, Aug. 10 (Xinhua) -- In a bid to prevent millions of deaths and suffering every year from malnutrition, the Geneva-based World Health Organization (WHO) launched an online initiative on Wednesday.The e-Library of Evidence for Nutrition Actions (eLENA), according to WHO, offers the latest advice on tackling the three main forms of malnutrition, including undernutrition, vitamin and mineral deficiencies, as well as overweight and obesity.The recommendations by eLENA to tackle malnutrition include promoting breastfeeding and fortifying staple foods with vitamins and minerals such as iron and folic acid for wheat and maize flours.It also recommends using multiple micronutrient powders to fortify foods for children aged between six and 23 months.To prevent anaemia, daily iron and folic supplements are advised for pregnant women, and intermittent iron and folic acid supplementation is recommended for menstruating women and preschool and school-age.While overweight and obesity affect around 1.5 billion adults over age 20, and more than 40 million children aged under five across the world, underweight is the leading risk factor for many diseases in low-income countries and represents about six percent of the world medical burden, WHO statistics showed.

BEIJING, Sept. 26 (Xinhuanet) -- Weather forecasts showed that Thursday or Friday might be suitable for launching the Tiangong-1 spacecraft, experts said.The unmanned spacecraft, part of China's first spacecraft rendezvous and docking mission, was set to blast off from the Jiuquan Satellite Launch Center in Northwest China at an appropriate time between Tuesday and Friday.But the latest weather forecast showed that Tuesday and Wednesday would not be suitable for a launch, Cui Jijun, chief commander of the mission's launch site system, was quoted by China National Radio as saying on Sunday.A precondition for launching is that the average wind speed at the launch site should not be faster than 10 meters a second. The upper-level wind, at 300 meters to 25,000 meters above the Earth, should be no faster than 70 meters a second.The 8.5-ton Tiangong-1 spacecraft and the Long March II-F rocket stand at the Jiuquan Satellite Launch Center on Sept 20. The spacecraft is set to blast off at an appropriate time between Tuesday and Friday.If the wind is too strong, the rising rocket carrier could wiggle and pose a danger, experts said."Everything is ready now except for the right weather," Cui said.On Sunday afternoon, all systems of the Tiangong-1 project went through a joint maneuver, he said. Before that, the 8.5-ton spacecraft, and the Long March II-F rocket that will carry it skyward, were positioned onto the launch pad last Tuesday.Engineers carried out checkups on the conditions of the rocket and the spacecraft, among many other tests in the past few days. All preparation work is done except for fuel loading, he said.Wang Xiaoqing, a publicity official at the launch site, said that the fuel loading usually begins one day before the launch. Once the fuel is loaded into the carrier vehicle, the launch becomes "irreversible".Tiangong-1, or Heavenly Palace 1, will serve as "a target spacecraft" for three rendezvous and docking experiments.The spacecraft rendezvous and docking missions are expected to pave the way for the building of a planned space station scheduled for 2020, previous reports said.Following Tiangong-1, an unmanned Shenzhou VIII spaceship will blast off from the Jiuquan Satellite Launch Center later this year.Lu Jinrong, chief engineer of the mission's launch site system, said that it is rare that two launches of China's manned space program are scheduled in half a year."In the past, the launch site carried out one launch a year, or even one every two to three years," he said."We are already in a high-frequency launch period."

HELSINKI, Aug. 21 (Xinhua) -- The Finnish company Spektikor has recently developed a novel type of disposable heart rate indicator, local media reported on Sunday.Different from a conventional heart rate monitor, it is a speed heart rate indicator designed for first aid professionals and specially used in first aids in major accidents, disasters and other crises.According to Spektikor, the product is consisted of a heart rate sensor with two EKG electrodes and a LED indicator, which are connected by a 35-cm-long wire.In operation, the sensor is placed on a patient's chest and the LED indicator is sticked to the patient's cheek. If the heart rate is within the normal range, the LED indicator will flash green with each beat. If the heart rate is dangerously low or high, the light will turn red.The product will help hospital staff speed up their work considerably as it is not necessary to check the pulse manually. In addition to saving time, it will also enhance safety, as the LED indicator can be seen clearly at a glance.The market prospect of the disposable heart rate indicator is quite optimistic as there is a worldwide need for the product.

ISLAMABAD, Sept. 11 (Xinhua) -- Chinese ambassador to Pakistan declared on Sunday that the Chinese government will provide an emergency humanitarian aid worth 30 million RMB (4.7 million U.S. dollars) to Pakistan to help its relief efforts.In light of the immense damages caused by the floods in some parts of Pakistan, Chinese Ambassador to Pakistan Liu Jian called on Pakistani Foreign Minister Hina Rabbani Khar on Sunday to express sympathy and solidarity of the Chinese people toward Pakistani people and declared that the Chinese government will provide the emergency humanitarian aid.Diplomats and staff of the Chinese Embassy in Islamabad have recently voluntarily donated 600,000 rupee (about 6860 U.S. dollars) to the people who hit by the floods. The Chinese ambassador handed over the donation to Pakistani side on Sept. 8.On Sept. 9, Chinese Foreign Minister Yang Jiechi sent a message to his Pakistani counterpart H.E. Hina Rabbani Khar, expressing his profound condolence to the victims and sincere sympathy to the affected people of the floods.The Chinese foreign minister said that China, as Pakistan's close friend, feels as much pain as Pakistan does and is ready to provide help to the best of its ability, in line with Pakistan's needs. He is convinced that the Pakistani people will definitely prevail over the natural disaster and rebuild their homes at an early date.
