SAN FRANCISCO, March 29 (Xinhua) -- Computer networking equipment giant Cisco Systems Inc. on Tuesday announced the intent to buy privately-held software company newScale Inc., in a move to complement and expand its offerings in cloud computing.Based in San Mateo in the U.S. state of California, newScale provides software that delivers a service catalog and self-service portal for information technology (IT) organizations to select and quickly deploy cloud services within their businesses.Founded in 1999, the company now has more than two million users worldwide, including 20 percent of the Fortune 50 companies, according to information posted on newScale's website."With the acquisition of newScale, Cisco will be able to accelerate the deployment of cloud services through a service catalog and self-service portal that allows customers to easily manage their IT infrastructures," Parvesh Sethi, Cisco's senior vice president, noted in a statement.Cisco said it expects to close the deal in the second half of its fiscal year 2011, without disclosing financial terms.

BEIJING, Jan. 26 (Xinhua) -- There is some part of China that could use additional water -- the drought-hit north, even while the central government is grappling to soak up excess liquidity to contain price hikes.The dry spell has continued for months in the grain production regions in northern China, setting off concerns that it might threaten China's grain output and thus cause food price hikes, a major contributor of the country's inflation in recent months.The bad weather came and may aggravate China's battle on price hikes, including higher interest rates and reserve ratios. The government also introduced price caps and promised increases in supplies to stabilize prices.Meteorological and agricultural experts said it is still too soon to predict a decline in grain output. However, they worried that if the drought continues into the spring, grain output will fall and push up food prices.DRY SPELLWater shortages have been gripping nine provinces since October last year, including the six major wheat producing regions in China -- Shanxi, Shandong, Hebei, Henan, Anhui and Jiangsu -- which contribute more than 80 percent of the country's total wheat output.Further, rainfall in the six provinces averaged only 40.2 millimeters since October last year, down 53 percent compared with previous years, according to the National Climate Center.As of Monday, 60.39 million mu (4.02 million hectares) of crops throughout the nation were plagued by drought, according to the latest statistics from the Office of State Flood Control and Drought Relief Headquarters."There have been no rains for four months. It has been too long," said Song Qingguo, a farmer at the Xitiegang village of Qixian County in Henan, where winter wheat output accounts for almost one-fourth of the country's total."Wheat output will probably drop if such a situation continues," he worried.At present, some 15.86 million mu of wheat is exposed to drought, according to Yang Biantong, an official with Henan's water authorities.Another key wheat growing province of Shandong is facing its worst drought in 60 years, local authorities said. About 2 million hectares of land used for growing wheat, or 56 percent of the wheat-planting areas in the province, have been hit by drought, and the area is expanding, the Shandong provincial flood control and drought relief headquarters said.H Scientists say it is a result of the La Nina effect that is also responsible for the harsh winter gripping large parts of China's south, which also affected production and transportation of vegetables and other food.The Ministry of Commerce said Tuesday that Chinese farm produce prices rose for a fourth consecutive week, through Jan. 23, with the wholesale prices of 18 staple vegetables growing 12.6 percent week on week. One reason for the price hike was the freezing weather in the south, it said."The current drought in China is the second worst during the same period of time since 1961 because of the adverse weather", said Zhang Peiqun, director with the weather forecast department of the National Climate Center.The bad weather will persist in the following period of time, which means the drought in the north and the cold snap in the south will continue, Zhang said.The China Meteorological Administration forecast on Wednesday that parts of Hubei, Hunan, Anhui and Zhejiang provinces will have heavy snow or snowstorms in the coming three days. Also, icy rain will slash parts of Guizhou and Yunnan provinces.

LOS ANGELES, May 8 (Xinhua) -- Kids born in the spring and summer months might be more likely to develop celiac disease, U.S. researchers have found.Researchers from the Massachusetts General Hospital for Children drew the conclusion after examining data on 382 children diagnosed with celiac disease at between 11 months and 19 years of age, HealthDay News reported on Sunday.The study found that in the 15- to 19-year-old set, birth season appeared to make no difference, but among 317 children younger than 15 years of age, 57 percent were born in the "light" season of March through August, compared with 43 percent who were born in the "dark" season of September through February.The findings suggest that the higher incidence of this autoimmune disease may be related to a combination of seasonal and environmental factors, the report said.Celiac disease is a digestive disorder triggered by consuming the protein gluten, which is primarily found in bread and other foods containing wheat, barley or rye. It can damage the small intestine and make it difficult to absorb certain nutrients, causing problems ranging from abdominal pain to nerve damage.Even though the exact cause of celiac disease is unknown, potential triggers include the timing of infants' introduction to gluten, and viral infections contracted during the first year of life.The study's findings suggest the season of a child's birth is another potential risk factor for the disease.The researchers pointed out that infants are generally introduced to solid foods containing gluten at around six months of age, which for spring and summer babies would coincide with cold and flu season.Based on the findings, the age at which gluten is first offered to some babies may need to be altered, said the study's lead researcher, Dr. Pornthep Tanpowpong. "If you're born in the spring or the summer, it might not be appropriate to introduce gluten at the same point as someone born in the fall or winter," said Tanpowpong. "Although we need to further develop and test our hypothesis, we think it provides a helpful clue for ongoing efforts to prevent celiac disease."The study also noted that exposure to sunlight may also play a role in celiac disease, since vitamin D deficiency has been associated with the disease.The study was presented Sunday in Chicago during Digestive Disease Week, an international gathering sponsored by the American Gastroenterological Association and other organizations, HealthDay News said.Because the study was presented at a medical meeting and is small, its findings should be considered preliminary until published in a peer-reviewed journal and confirmed in other research, the report said.

BEIJING, Feb. 13 (Xinhua) -- Chinese State Councilor Meng Jianzhu left here Sunday for visits to the Democratic People's Republic of Korea (DPRK), Laos, Singapore and Malaysia.Meng, who is also Chinese Minister of Public Security, is traveling to the countries at the invitation of the DPRK Minister of People's Security Ju Sang Song, Lao Minister of Public Security Thongbanh Seng-aphone, Singaporean Minister for Home Affairs and Minister of Law K Shanmugam, and Malaysian Minister of Home Affairs Hishiammuddin Tun Hussein.

WASHINGTON, April 11 (Xinhua) -- In the first clinical trial of gene therapy for treatment of intractable pain, U.S. researchers from the University of Michigan's Department of Neurology observed that the treatment appears to be able to provide substantial pain relief.In a study published online in the Annals of Neurology and seen on Monday, the researchers showed that the novel agent NP2 is safe and well-tolerated. In addition, measures of pain in the treated patients suggested that NP2 may provide a substantial analgesic effect.NP2 is a gene transfer vector that expresses the naturally- occurring opioid peptide enkephalin. In preclinical work in animals, David Fink, chair of the Department of Neurology, and his coworkers had demonstrated that injection of NP2 into the skin reduces pain in models of pain caused by nerve damage, inflammation or cancer.In the clinical trial, 10 patients with unrelenting pain caused by cancer were injected with the gene transfer agent in the area of skin related to the location of pain."The concept underlying this therapeutic approach is that injection of NP2 into the skin results in uptake into the nervous system and the production and release of a pain-relieving chemical in a controlled site in the pain pathway," says Fink. "In the study, patients who received the low dose of vector showed little reduction in pain; patients receiving the higher doses showed a greater than 80 percent reduction in pain over the course of four weeks following treatment."Fink's laboratory has been working on the use of modified herpes simplex virus-based vectors that are taken up by sensory nerves following skin injection to develop therapies for diseases of the nervous system for more than 20 years. Patents related to this technology have been exclusively licensed by Diamyd Medical, a publicly-traded Swedish biotechnology company that sponsored the trial, and the human-grade vector NP2 was produced by Diamyd, Inc, the U.S. subsidiary of Diamyd Medical.A phase 2 trial to compare NP2 to a placebo control has already been initiated under sponsorship from Diamyd.
