WASHINGTON, Oct. 19 (Xinhua) -- A total of 25 people have been killed in 12 U.S. states in a listeria outbreak traced to Colorado cantaloupes, the U.S. Centers for Disease Control and Prevention ( CDC) said Wednesday.The number of people sickened by the tainted cantaloupes has reached 123 in 26 states, with Pennsylvania reporting its first case. One of the ill patients, a pregnant woman, suffered a miscarriage, the CDC said in a telebriefing.The listeria outbreak has been the most deadly one since 1998, according to the CDC.Listeria is a common bacterium that typically causes mild illness in healthy people, but can cause severe illness in older people and those with compromised immune systems. It also can cause miscarriages and stillbirths in pregnant women and severe infections in new babies.The CDC estimates that about 48 million people in the U.S. each year get sick from tainted food, with about 128,000 hospitalized and 3,000 deaths.

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. 11 (Xinhuanet) -- An experimental drug that can remove amyloid plaques from the brains of Alzheimer's patients is being developed by Swiss Roche Holding AG in a small early-stage study, according to a report published in the Archives of Neurology on Monday.Researchers suspect the build-up of such plaques may be a cause of the memory robbing disease, although that theory has yet to be definitively proved. Gantenerumab, a biotech drug designed to bind to amyloid plaques in the brain and remove them, is being targeted at the early stages of Alzheimer's with the hope it can slow progression of the disease while patients are still able to function.The Phase I study of 16 Alzheimer's patients tested gantenerumab at two doses against a placebo over six months of treatment.The Roche drug led to a dose-dependent reduction of brain amyloid, while amyloid load increased in patients receiving a placebo, the report said.The next step will be to investigate whether removal of brain amyloid translates into clinical benefit for patients at doses of the experimental drug that are well tolerated and safe, the report said.Much larger trials and further study will be needed to fully understand how gantenerumab works and whether it can stave off Alzheimer's, said the report.Roche is approaching the disease far earlier because amyloid accumulates for 15 years before dementi.

CHANGCHUN, Nov. 13 (Xinhua) -- An infrared camera set up by the World Wildlife Fund (WWF) and forestry authorities in northeast China's Jilin province has captured images of a wild Siberian tiger in the Wanda Mountains.Zhu Jiang, head of the WWF Northeast China Program Office, said Saturday that the photos, taken earlier this month, are the first images of a wild Siberian tiger taken in the mountainous area.He said the evidence consolidates the mountains' role as an important habitat for the endangered species, and reinforces the need for local authorities to tighten protection measures, especially clearing animal traps and improving animal rescue efforts.The agency estimates that there are fewer than 20 wild Siberian tigers remaining in China. They live in mountains in the northeastern Heilongjiang and Jilin provinces.Zhu said animal traps still pose a major threat to the safety of wild Siberian tigers and their prey.A wild Siberian tiger was found dead with a trap around its neck in the city of Mishan, Heilongjiang, in October.A WWF survey found an average of 1.6 traps for every 10 km of distance covered in the Siberian tiger nature reserves in Heilongjiang and Jilin last winter."The WWF hopes to cooperate with local governments to protect Siberian tigers and restore their habitats," Zhu told Xinhua. "We aim to help double the population of wild Siberian tigers in China by 2022, the next Year of the Tiger," he said.

MILAN, Italy, Dec. 1 (Xinhua) -- Italy has a new HIV infection every three hours on average, the national department of health said in a statement during the World AIDS Day commemoration Thursday.According to the statement, there were about 3,000 new infections in the country in 2010, with nearly one third of those affecting a foreigner.At least 157,000 people are presently estimated to be HIV-positive in Italy, though the country's AIDS infections and deaths continue to register a negative trend.Nearly 90 percent of the new patients acquired the virus through unprotected sex, and were mostly from the northern regions.People discovered to be HIV-positive in 2010 had an average age of 39 for men and 35 for women, more than a third of whom were diagnosed at an advanced stage of the disease, the statement said.Misinformation and a lack of preventive measures are a great cause for concern, Milan's councillor for social services and health Pierfrancesco Majorino told Xinhua at a campaign launched in Milan's La Scala Square."We have to keep in mind that AIDS is something very close to each of us, and adopt all most effective campaigns to provide complete and correct information," he said.A red ribbon -- the international symbol of AIDS awareness -- was formed by a group of people at the center of the square to remind everyone to stay alert to the disease.On World AIDS Day, disease prevention and health information campaigns were launched throughout Italy, including free ultra-rapid HIV-screening tests.
