SHANGHAI, Dec. 9 (Xinhua) -- China's homegrown C919 large passenger plane has finished its preliminary development review and entered the development phase, a senior executive of Commercial Aircraft Corporation of China Ltd. (COMAC) in Shanghai said Friday.An expert team of the C919 project has approved the overall preliminary development review (PDR) of the passenger jet, said Jin Zhuanglong, president of the Shanghai-based COMAC.It is expected that the manufacturing process for the components of the prototype will begin by the end of 2011.COMAC signed a deal to sell 20 C919 large passenger planes to China Aircraft Leasing Company Limited (CALC) on Thursday.Up to now, the users of C919 large passenger planes have reached 10 and total orders amount to 215 units.COMAC said earlier it would develop both 168-seat and 156-seat models of the jet, with more models to be developed in the future.It also said that test flights for the single-aisle C919 were scheduled for 2014, and delivery is slated for 2016.

VIENTIANE, Dec. 5 (Xinhua) -- Laos and China pledged on Monday to deepen military exchanges and cooperation, strengthen unity and friendship between the two countries'militaries and work together to maintain regional peace and stability.The vows came out of the meeting between the Lao Deputy Prime Minister, Minister of National Defense Douangchay Phichith, Lao Deputy Minister of National Defense Sanyahak Phomvihane and the visiting Deputy Chief of General Staff of the Chinese People's Liberation Army (PLA) Cai Yingting.Douangchay said the Lao side appreciates the Chinese side's long-term support and help which have contributed to the Lao social economic development and national defense building. The Lao Party, government and military attach great importance to developing relations with China, and are willing to make joint efforts with the Chinese side to further promote the two states and militaries' ties to a new level.Sanyahak said that no matter how changes in the international and regional situation, the solid traditional friendship between the two countries' people and militaries won't change.

In recent years, the bilateral ties continue to see a healthier and stabler development, especially after the two countries have established a comprehensive strategic and cooperative partnership.The Chinese side will continue to maintain close high-level contacts with Laos, enhance substantial cooperation, and strengthen friendly coordination, in order to contribute to the bilateral ties, and regional peace, stability and prosperity, Cai added.The Cai-led Chinese PLA delegation arrived in Lao's capital of Vientiane on Monday at the invitation of the Lao Ministry of National Defense, kicking off their friendly visit to Laos.

KUWAIT CITY, Nov. 27 (Xinhua) -- Two warships from China on Sunday docked at Kuwait's Shuwaikh port to start a five-day official visit to the Gulf Arab emirate.The tour by the destroyer "Wuhan" and the frigate "Yulin" marked the first visit by Chinese naval vessels to Kuwait since the two countries established diplomatic ties 40 years ago."This visit marks a historic occasion and Kuwaiti navy looks forward to future cooperation to improve the relationship and friendship between our two navies," said Colonel Khaled Ahmad Abdallah from Kuwait's navy.The flotilla was part of the ninth Chinese naval convoy to conclude its escort mission in the Gulf of Aden and waters off Somalia.Commander of the flotilla Guan Jianguo hopes the visit would enhance mutual cooperation between the two navies, which in turn would contribute to boosting bilateral relations.The flotilla would visit Oman after its stay in Kuwait.

KATHMANDU, Oct. 30 (Xinhua) -- "One of the major problems of death due to breast cancer in Nepal is poverty and untimely diagnosis," said Dr. Abish Adhikari Oncologist at the Bir Hospital in Nepali capital Kathmandu in an exclusive interview with Xinhua on Sunday.Adhikari said that the other reason why breast cancer leads to death of women is "women are not decision makers in their houses"."Many people who come here do not want to treat their wives or daughters because of the expenses as they are poor and it is really expensive here to treat cancer," Adhikari said.According to the Nepal Cancer Relief Society, of all cancer cases among the Nepali women and teenage girls as well, 60 percent is of breast cancer.Unverified rough data of the breast cancer patients in Nepal are above 50,000.Adhikari added that women are shy to talk about the problems of breast. They do not go to hospitals for the check up until they are bedridden and at the time they reach hospital they are mostly in the advanced stage.The major causes behind the breast cancer in Nepal are heredity, late pregnancy, consumption of alcohol and smoking. However, unawareness about it remains another major problem that leadind to death of many women in Nepal.Moreover, the rural women in Nepal are unaware about breast cancer, and if they are having some problem, they tend to hide it.Talking to Xinhua, Sajani Manandhar, General Secretary of Richa Bajimaya Memorial Foundation, a cancer awareness raising group said that the major cause of the preventable cancer in Nepal is unawareness.Also a nurse by profession, she said that no one bothers about mammography or regular checkup but are diagnosed at the very late stage.There are less than five hospitals that provide mammography service in the country.Roshani Chitrakar, 48 who is in advanced stage of cancer said that she did not told anyone while she found something unusual in her breast because it was not painful."I took it normally, but when I thought it might be a cancer and told my family and I was already in the advanced stage," she said.Her daughter, Roji Manandhar, said that the doctor has already told that she will not be living long. She is having difficulty even to eat currently.Another cancer patient, 67 years old farmer, Nakkali Nahakhusi said that she told her husband when she found her breast unusual. Her husband, former armyman, immediately took her to the hospital when she told about the problem.Now, she is already cured, and said with smilingly that the god of death did not want to take me away.She said that awareness should be raised because cancer is curable at the early stage.

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.
