LOS ANGELES, April 3 (Xinhua) -- People with lower levels of vitamin D are more likely to have stiffer arteries and an inability of blood vessels to relax, U.S. researchers have found.This finding also applies to people who are in general good health, according to researchers from the Emory University School of Medicine.The researchers presented their findings on Sunday at the annual American College of Cardiology meeting in New Orleans.Impaired vascular health in correlation with lower vitamin D levels contributes to high blood pressure and the risk of cardiovascular disease, the researchers say.The study involved 554 participants, with the average age of 47 and generally healthy.The average level of 25-hydroxyvitamin D (a stable form of the vitamin reflecting diet as well as production in the skin) in participants' blood was 31.8 nanograms per milliliter. In this group, 14 percent had 25-hydroxyvitamin D levels considered deficient, or less than 20 nanograms per milliliter, and 33 percent had levels considered insufficient, less than 30 nanograms per milliliter.The researchers monitored the ability of participants' blood vessels to relax by inflating and then removing a blood pressure cuff on their arms. To allow blood to flow back into the arm, blood vessels must relax and enlarge -- a change that can be measured by ultrasound. The researchers also made other measurements of smaller blood vessels and examined the resistance to blood flow imposed by the arteries.

CARACAS, March 30 (Xinhua) -- The number of confirmed cases of the A/H1N1 influenza in Venezuela has risen to 482 this year, Health Minister Eugenia Sader said on Wednesday.According to the latest report, the state of Merida in southeastern Venezuela has 189 A/H1N1 influenza cases, the biggest number ever reported, which was followed by the Capital District of Caracas with 112 cases. The other 181 cases were confirmed in 17 of 24 Venezuelan states.The first case for this year was reported in Merida earlier this month.Sader said that the Venezuelan government was trying to prevent the spread of the disease.

JERUSALEM, May 2 (Xinhua) -- Traditional farming may have found an ally on the Internet, via an Israeli "cloud-based" software system that enables farmers to get professional information and tips from colleagues worldwide.And IBM is interested in what they have to say.Agriculture Knowledge On-Line (AKOL) says its Internet-based system can aid global agriculture by utilizing the collective knowledge of kibbutzim (communal farms in Israel) and other agricultural experts, to offer small farmers personalized solutions to improve dairy output and crop production, and better prevent droughts.Owned by Kibbutz Bror Hayil in southern Israel, the software house has recently signed a cooperation and development agreement with IBM to manage access and technology issues."What we do here is like a bank of information and IBM provides the special tools for the end users," AKOL's CEO Roni Shani told Xinhua, "and you can do what we call 'agricultural market.'""For example, if someone in Australia needs advice on how to grow their crops better, they can just ask our advice or search through our database to find the best product for the country they 're growing the crops in," Shani said."Let's say someone in India, a small farmer, has a problem with their crop or chickens," Shani explained, noting that "it's usually very expensive and time consuming to get someone to come and check what is wrong."But, for a monthly fee, a basic subscription service enables the end user to access the software database, which allows "the farmer to just look at the pictures and pick the one that will explain what the disease or problem is and offer a solution, and if it is available in their country."AKOL claims about 1,000 customers over the globe."We just started developing it for use outside of the kibbutz with IBM's help," Shani said, "and we are developing it also in other parts of the world, like China. Right now we're cooperating with the Chinese government to help milk producers get the most out of their milking systems."Israel is one of the leading countries in milk production, with each cow yielding around 12,000 liters of milk a year on average. Two Chinese provinces plan to use AKOL's milking control system, in order to better manage their herds and equipment and increase milk production."And this is just the beginning," Shani explained, "because we are also working with other developing countries. This software will help millions of small farmers in rural or impoverished areas, that will be able to get advice and benefit from other farmers' experience on the spot and at a very affordable rate."

BEIJING, Jan. 22 (Xinhua) -- Chinese President Hu Jintao's latest state visit to the United States bore rich fruit and opened a new chapter of cooperation between the two countries, Foreign Minister Yang Jiechi said Saturday.The tour, from Tuesday through Friday, came at the beginning of the second decade of the 21st century, on the 40th anniversary of the resumption of contact between the two countries and on the opening year of China's 12th five-year plan for national socioeconomic development, Yang noted.Meanwhile, the international situation was witnessing deep and complicated changes, and the China-U.S. relationship was forging ahead with increasing momentum while inevitably encountering some differences and disputes, he said.Against such a backdrop, the Chinese president held frank and in-depth talks with his U.S. counterpart, Barack Obama, and many other senior political figures, and reached important consensus on bilateral relations and a host of major regional and global affairs, Yang said.During the tightly scheduled trip, which saw Hu attend nearly 20 events in Washington and Chicago within 68 hours, the Chinese leader also reached out to the U.S. public, conveying China's resolution to advance China-U.S. ties, highlighting China's commitment to peaceful development and presenting China's image of peace, development, opening-up and progress, Yang said.The U.S. and international media, he added, attached great importance to and spoke highly of Hu's trip, hailing it as a historic visit at a crucial moment and whose significance was manifested partly in the top level reception with full pomp and ceremony given by the U.S. government.In summary, the latest step in China-U.S. diplomacy achieved rich results and cast a far-reaching influence not only upon the two countries themselves but upon the whole world, the Chinese foreign minister said.

LOS ANGELES, March 18 (Xinhua) -- The moon will move closer to Earth than it has been in more than 18 years Saturday night, space. com reported on Friday.On Saturday afternoon at 3 p.m. Eastern Daylight Time (1900 MGT) , the "supermoon", as dubbed by some observers, will arrive at its closest point to the Earth in 2011: a distance of 221,565 miles ( 356,575 kilometers) away, and only 50 minutes earlier, the moon will officially be full, the report said.At its peak, the supermoon may appear 14 percent larger and 30 percent brighter than lesser full moons (when the moon is at its farthest from Earth), weather permitting, said the report.Yet to the casual observer, it may be hard to tell the difference, according to the report.Scientists say it is a fluke of orbital mechanics that brings the moon closer to Earth.The supermoon will not cause natural disasters, such as the Japan earthquake, NASA scientists say.In December 2008, there was a near-supermoon when the moon turned full four hours away from its perigee - the point in its orbit that is closest to Earth. But this month, the full moon and perigee are just under one hour apart, promising spectacular views, depending on local conditions, the report said.
