BEIJING, March 15 (Xinhuanet) -- The number of Alzheimer patients is growing rapidly, so is that of unpaid caregivers, says a report released Tuesday by the Alzheimer's Association.Nearly 15 million caregivers, most of them family members but also friends, are providing billions of hours of unpaid care for Alzheimer's patients and other forms of dementia in the U.S. — 37 percent more than last year, the report says.Alzheimer's is the sixth leading cause of death in the nation, and the only one among the top 10 that have no prevention or cure, says William Thies, chief medical and scientific officer of the Alzheimer's Association.However, if people were more aware of early symptoms and were diagnosed sooner, then planning could help ease stress on patients and caregivers, according to Beth Kallmyer, senior director of constituent services of Alzheimer's Association."The toll on families is devastating," says Kallmyer, "Stress is extremely high, and one-third are experiencing depression."The time and stress of caring for an Alzheimer’s patient takes a physical toll, translating into nearly 8 billion dollars worth of extra health care costs for caregivers, the report says.

IWATE, Japan, March 14 (Xinhua) -- A 15-strong Chinese international search and rescue team Monday morning set out to join the relief work in Oofunato, Iwate, a city severely damaged by a 9.0-magnitude earthquake Friday.The Chinese international search and rescue team, which arrived in Oofunato at around 10:30 p.m. Sunday night, is the first overseas team to join and help out the relief work in the city.Team leader Yin Guangfui said they have brought along life exploration device and some other equipment to help carrying out the rescue.The team, with good experience in search and rescue, will strive to do the relief work, Yin added.The team members, including rescue and medical personnel, gathered at a primary school in Oofunato on Sunday and set off at 7:30 a.m. to the disaster-hit area together with the Japanese rescue teams after a briefing. The team is expected to be here for seven to 10 days.The catastrophic earthquake hit northeast of Japan on March 11, triggering severe tsunami and causing extensive damage and loss in different areas. According to local media, a total of 985 people have been confirmed dead, 707 others injured and over 1,700 others missing.

UNITED NATIONS, April 1 (Xinhua) -- UN Secretary-General Ban Ki- moon on Friday called for greater public awareness of autism, in order to fight the stigma and discrimination facing those who suffer from the disorder.The statement came in a message to mark the annual World Autism Awareness Day, observed globally on April 2."Children and persons with autistic conditions face major challenges associated with stigma and discrimination, as well as a lack of access to support," said Ban."Far too many suffer terrible discrimination, abuse and isolation, in violation of their fundamental human rights," he added.Autism is a disorder that affects the brain's development of social and communication skills, and generally appears in the first three years of life."The number of children and people with autistic conditions continues to rise -- in every nation and in every racial, ethnic and social group," the secretary-general said.Ban said it is critical to support parents of children with the disorder and "create jobs for individuals with autism based on their skills and strengths, and improve public education to better meet the needs of students with autism."

BEIJING, April 14 (Xinhuanet) -- The discovery of a sharp-toothed dinosaur fossil in New Mexico, the United States, may bridge a gap in the evolution of the species, researchers said in Wednesday's journal Proceedings of the Royal Society B.Researchers from the Smithsonian Institution unearthed the dinosaur skull and neck vertebrae in Abiquiu, New Mexico, where it had remained buried for around 230 million years. The short snout and slanting front teeth of the find — Daemonosaurus chauliodus — had never before been seen in a Triassic era dinosaur, said Hans-Dieter Sues of the Smithsonian's National Museum of Natural History.Sues, curator of vertebrate paleontology at the museum, said the discovery helps fill the evolutionary gap between the dinosaurs that lived in what is now Argentina and Brazil about 230 million years ago and the later theropods like the famous Tyrannosaurus rex."Various features of the skull and neck in Daemonosaurus indicate that it was intermediate between the earliest known predatory dinosaurs from South America and more advanced theropod dinosaurs," said Sues."One such feature is the presence of cavities on some of the neck vertebrae related to the structure of the respiratory system," he added.The discovery suggests that there is still much to be learned about the early evolution of dinosaurs."The continued exploration of even well-studied regions like the American Southwest will still yield remarkable new fossil finds," Sues said.
