WELLINGTON, May 24 (Xinhua) -- New Zealand researchers have found a way to stop the growth of certain cancer tumors by " silencing" a group of PAX genes, members of a small family of genes that play important roles in embryonic development, but also allow cancer cells to grow and divide in adult tissue.In an article published in UK medical journal Oncogene, Otago University Professor Michael Eccles and colleagues revealed how they used the PAX8 gene to kill cancer cells.After detecting high levels of PAX8 protein in the majority of kidney, ovarian and thyroid cancers they studied, the researchers used molecular techniques to silence the PAX8 gene in several cancer cell lines."We found that these PAX8-depleted cancer cells ceased growing and dividing. The cells were essentially stopped in their tracks through the failure of multiple mechanisms and pathways crucial to their cell division cycle. They then entered into a state called senescence in which they no longer divided, and after that they ultimately died," Eccles said in a statement from the university Tuesday.The findings suggested that PAX8 could be a good target for the development of new cancer therapies, he said."Any resulting drugs would be a long way down the road, but in the meantime this research helps confirm that a focus on PAX genes may prove to be a fruitful line of attack against a number of cancers," he said.The research was supported by grants from the Health Research Council of New Zealand. It formed the main piece of work carried out by Otago doctoral graduate Caiyun (Grace) Li, now a postdoctoral fellow at Stanford University. Study co-authors also included Professor Antony Braithwaite and master's student Jen Nyman.In 2003, research led by Eccles discovered that proteins from one or more of the nine PAX genes were present in many common cancers. They found that "silencing" the gene expression of PAX2 in ovarian and bladder cancer cells, and of PAX3 in melanoma, led to the rapid death of the cells.

CANBERRA, April 1 (Xinhua) -- People who share bongs to smoke marijuana may be at risk of contracting pulmonary tuberculosis (TB) , Australian medical researchers warned on Friday.Dr Michael Hayes and Dr Susan Miles from Calvary Mater Hospital in Newcastle of Australia conducted the research, which centered on three recent TB cases in New South Wales.TB is caused by the bacteria Mycobacterium tuberculosis, which can be contracted by breathing in air droplets coughed from an infected person.The research suggested a link between active TB cases and shared bongs, which is the water pipes commonly used in marijuana smoking.According to Dr Hayes, the three young patients were regular or heavy cannabis users, and more recently there has been a fourth person in the region with similar characteristics had been diagnosed with TB.He said although the three initial cases were not related, there was concern about the high rate of positive contacts among people who had shared bongs with the active cases."Smoking marijuana is a cough-provoking activity and it is usually conducted in a confined environment that is conducive to the spread of the organism," he told Australia Associated Press.

BEIJING, Feb. 1 (Xinhua) -- A ceremony with a bonfire and firecrackers was held Tuesday night in the new seat of a quake-leveled county in southwest China's Sichuan Province, prior to the Chinese Lunar New Year on Thursday.The Lunar New Year, or Spring Festival, is the most important Chinese holiday. It is a time for family reunions, gift giving and fireworks.It will be even merrier for the survivors of the Wenchuan earthquake in 2008, who just moved into their new homes in the new town.The earthquake survivors are preparing for the first Spring Festival in their new homes.Xia Tianfeng of Beichuan County, Mianyang City, is sticking red paper decorations onto the windows of her new house for good luck in the New Year."We finally have our new house. Why wouldn't I be happy?" asked Xia.She and her family lived in a makeshift house for two years before moving into their new house one month ago.Dong Depa, 43, and his family moved into their new house in Yingxiu Town, the epicenter of the quake, five days ago."I can pay off the debt incurred to build the house in two years," said Dong, who spent only 30,000 yuan (4,541 U.S. dollars) for the house's construction and decoration, with the rest being shouldered by the government.Dong lost his two children in the quake but he and his wife have since had another child, a son."Last year, we spent the Spring Festival in the dormitory of the brick factory where I work as a cook. Now we can finally enjoy the festival in our own home," said Dong, unable to conceal his joy.Xia told Xinhua the ceremony for the new county seat was the real taste for a happy new year.Reconstruction has finished in the quake-hit zones in Sichuan, with most survivors now in their new houses.In Beichuan County alone, 96.5 percent of the survivors already have their new house.The new county seat is located in Yongchang Town, about 23 kilometers from the quake-leveled old one.The 8.0-magnitude earthquake struck southwest China on May 12, 2008, leaving about 80,000 people dead or missing.Waving goodbye to their temporary barracks, 7,397 households have been allocated new apartments, among which 3,504 households were former Beichuan residents, while others were from different Wenchuan earthquake-hits regions."The new apartment has already been simply decorated by the time I received the door key. With our new furniture, we can wait no longer to move into the home," said 45-year-old Xie Xinghe, a former resident of Beichuan.Including 50,000 yuan (about 7,575 U.S. dollars) in loans, Xie paid a preferential price of 79,600 yuan (about 12,000 U.S dollars) for the 100 square meter new apartment.Losing his only son in the earthquake, Xie and his wife adopted a one-year-old boy."It is the child who brings me new hope for the future," Xie said. Following the Lunar New Year celebration in his new home, Xie will try his best to work for some years to pay back the loan and save money to ensure a better education for his son."It is such magic to build a new town within three years, even so anywhere around the world. And we see it now," said Xu Zhenxi, director with the headquarter of new town program of Beichuan, which is supported by east China's Shandong Province.From May 25, 2009 to September 25, 2010, Shandong Province supported the new Beichuan county seat project, which was completed within 15 months.

LOS ANGELES, May 9 (Xinhua) -- Drinking alcohol may raise the likelihood among teenagers to spend more time on computers, a new study suggests.The study, conducted by researchers at Weill Cornell Medical College, was based on a survey of 264 teenagers, aged 13 to 17.Results showed that compared with teens who did not report drinking, those who drank alcohol in the last month used a computer more hours per week for non-school-related activities, including the use of social networking sites.Drinking was also linked to more frequent social networking and listening to and downloading music, according to the study published Monday in the on-line edition of the journal Addictive Behaviors.However, there was no demonstrated link between alcohol use and computer use for school work, neither there was strong link between video games and drinking or on-line shopping and drinking."While the specific factors linking teenage drinking and computer use are not yet established, it seems likely that adolescents are experimenting with drinking and activities on the Internet," said Dr. Epstein, assistant professor of public health at the college."In turn, exposure to on-line material such as alcohol advertising or alcohol-using peers on social networking sites could reinforce teens' drinking."Children are being exposed to computers and the Internet at younger ages. For this reason it's important that parents are actively involved in monitoring their children's computer usage, as well as alcohol use."Teenagers typically first experiment with alcohol at age 12 or 13, according to the study.Family risk factors include lax parental supervision and poor communication, family conflicts, inconsistent or harsh discipline and a family history of alcohol or drug abuse."According to a national study conducted by the Pew Internet and American Life Project, more than half of parents of teenagers had filters installed on the computers their child uses to block content parents find objectionable, yet many parents do not use any form of parental monitoring, particularly for older teens," Epstein said.
