WASHINGTON, Dec. 7 (Xinhua) -- Drugs that affect the levels of an important brain protein involved in learning and memory reverse cellular changes in the brain seen during aging, according to an animal study published Wednesday in the Journal of Neuroscience. The findings could one day aid in the development of new drugs that enhance cognitive function in older adults.Aging-related memory loss is associated with the gradual deterioration of the structure and function of synapses (the connections between brain cells) in brain regions critical to learning and memory, such as the hippocampus.Recent studies suggested that histone acetylation, a chemical process that controls whether genes are turned on, affects this process. Specifically, it affects brain cells' ability to alter the strength and structure of their connections for information storage, a process known as synaptic plasticity, which is a cellular signature of memory.In the current study, Cui-Wei Xie, of the University of California, Los Angeles, and colleagues found that compared with younger rats, hippocampi from older rats have less brain-derived neurotrophic factor (BDNF) -- a protein that promotes synaptic plasticity -- and less histone acetylation of the Bdnf gene. By treating the hippocampal tissue from older animals with a drug that increased histone acetylation, they were able to restore BDNF production and synaptic plasticity to levels found in younger animals."These findings shed light on why synapses become less efficient and more vulnerable to impairment during aging," said Xie, who led the study. "Such knowledge could help develop new drugs for cognitive aging and aging-related neurodegenerative diseases, such as Alzheimer's disease," she added.

BEIJING, Dec. 31 (Xinhua) -- The Red Cross Society of China (RCSC) has decided to shut down one of its fund-raising groups due to serious management flaws, as the group's alleged misuse of donations sparked public mistrust in charities.The China Business System Red Cross Society has been repealed for failing to establish a sound internal management system, maintaining a benefit-based relationship with a consulting company, and committing violations in financial and legal management, an investigation report said Saturday.The China Business System Red Cross Society, a group founded in 2001 by the China General Chamber of Commerce (CGCC) with the approval of the RCSC, engaged in charity fund raising in the commercial sector. Funds raised by the group are channeled directly to the RCSC.The group faced accusations earlier this year of misusing charity money after a young woman calling herself "Guo Meimei" claimed online to be a general manager of "Red Cross Commerce" and posted pictures on her tweets detailing her lavish lifestyle.Netizens related "Red Cross Commerce" to the China Business System Red Cross Society, and speculated that Guo might have funded her purchases by embezzling money from the Red Cross.In July, the RCSC suspended all operations of the China Business System Red Cross Society and started an investigation along with officials and experts from the Ministry of Supervision, the Chinese Academy of Social Sciences, a law firm and the CGCC.According to the investigation report, "Red Cross Commerce" does not exist, and Guo Meimei is not employed by the China Business System Red Cross Society or its cooperative enterprises.The RCSC says it is preparing to set up a public supervision committee, and it plans to invite people from all walks of life, including influential figures, to supervise its use of donations as a third party.Meanwhile, the RCSC is also building up an online service that will publicize information about all donations made to the Red Cross system nationwide, in a move to safeguard the rights of the public, including donors, and supervise the charity group's operations.The website is expected to be launched by the end of 2012, the RCSC said.The RCSC has also vowed to strengthen the supervision and management of its subsidiaries and promote transparency in donations, financial management, tendering and procurement, and fund distribution and use.

BEIJING, Nov. 13 (Xinhua) -- China has established an operation committee for management of the country's first space lab module, Tiangong-1, during its two-year orbit of earth.The committee will deal with operations planning, technical appraisal and flight control of the target orbiter after the unmanned Shenzhou-8 spacecraft returns to earth after its mission, the official website of China's manned space program said.The Tiangong-1 space lab module was launched on Sept. 29 and docked with Shenzhou-8 precisely on Nov. 3, China's first ever space docking attempt. The second docking between Tiangong-1 and Shenzhou-8 is scheduled for Nov. 14.The manned space program said earlier that the same target orbiter Tiangong-1 will accommodate another two docking missions performed by two other Shenzhou spaceships, at least one of which will be manned.The 8.5-tonne Tiangong-1 is the first space lab module that China has built, and the committee will also be the first in taking care of a long-running space asset.The operation committee for Tiangong-1 heralds China's manned space program entering a new phase for lengthy flight missions, Niu Hongguang, director of the operation committee, said on the website www.cmse.gov.cn.The orbiting module management will include taking care of the space lab, making preparations for any further docking tests and gathering experience for building a future space station, Niu said.

SUVA, Oct. 3 (Xinhua) -- It is Pinktober again and Fiji like the rest of the world will be raising awareness of breast cancer too, Fiji Cancer Society Chairperson and breast cancer awareness month President Nirmala Nambiar has said."Join the fight against breast cancer through early detection and awareness." This is the message the Fiji Cancer Society is sending out this October, which is breast cancer awareness month, worldwide.Fiji Cancer Society Chairperson and breast cancer awareness month President Nirmala Nambiar said, "Fiji continues to have a high incidence of breast cancer deaths with large number of tumors presented to health professionals at a late stage due to the stigma of having the disease."In the first quarter of 2011, there were 46 new breast cancer cases recorded, whilst there were 33 new cases in the same period last year."The figures could be scary but one must understand that as the awareness increases in our communities the number of cases recorded increases," she warned.Men and women should be aware that age, obesity and family history are all factors that contribute to the risk of developing the disease.This October the Fiji Cancer Society has planned a number of events all targeted to raise awareness since the lack of information and education is dangerous.Nambiar said through partnership with the Ministry of Health, Oxfam Clinic in Suva and the Fiji Nurses Association, supported by the sponsorship of Colgate Palmolive, the focus this year is on reaching out to the rural community and making a difference to the lives of the poor and unprivileged."We have free checkups planned for the month at the major villages from Vunidawa, Korovou and Valelevu to Lami at the other end and hope that we will be able to support the women in this area who may not be able to have a check- up otherwise.According to the official, the society's western branch continues to arrange free check- ups with the support of the Patan Clinic.The awareness and free checkups have also been arranged for corporate organizations at their request and if we are not able to provide all this during October we will continue to schedule them for the following month.The Society's thanks go to Suva Private Hospital for offering half price mammograms for the month of October, Nambiar said, adding a common issue with Fiji women, according to doctors at the hospital, was the return rate."Once they hear the news that they have cancer, many women don' t return because of the fear of what's next. Hence the Society is working with the hospitals and helping counsel patients to get them back for treatment rather than fight the losing battle, since 70 percent of cancer cases can be saved through early detection and treatment," she said.The Fiji Cancer Society strongly believes that the success of the awareness program this month will set the platform for the society's ongoing initiative to drive and raise the community's understanding, get them involved and make them take care of each other.
