CANBERRA, Sept. 7 (Xinhua) -- A team of Australian and U.S. scientists on Wednesday said they discovered a genetic defect, which can lead to Leigh syndrome, a rare disorder which affects the central nervous syndrome.The scientists tested more than 1000 genes by encoding proteins active in two individuals who suffer from the illness. They used a new technique known as next-generation DNA sequencing to examine the genes.The gene they discovered encodes an enzyme which is found in the mitochondria which are subsets of cells. Without this enzyme the mitochondria do not translate proteins efficiently, and this then causes Leigh syndrome.According to David Thorburn, from the Murdoch Children's Research Institute in Melbourne, the discovery shows the enormous potential of the new technology."These findings demonstrate the ability of sequencing technologies to improve diagnosis," Professor Thorburn said in a statement released on Wednesday."Although it isn't clear in the case of Leigh syndrome whether the precise molecular diagnosis will necessarily lead to therapies, the current findings represent a meaningful service."He added that diagnosis of the disease along with its specific genetic cause can also be informative about the risk a couple has of having another affected child. The diagnostic information can help in decisions about whether and how to pursue alternative means of having children, for instance through the use of donor sperm or eggs.The research team consisted of scientists from Australia's Murdoch Institute as well as the Broad Institute in the U.S.In Leigh syndrome, infants are born apparently healthy only to develop movement and breathing disorders that worsen over time, often leading to death by the age of three. The problem is that the mitochondria responsible for powering their cells cannot keep up with the demand for energy in their developing brains.

BEIJING, Aug. 1 (Xinhua) -- The after-tax CIF (cost, insurance and freight) price of China's jet fuel imports has been set at 7,768 yuan (1,206 U.S. dollars) per metric ton for August, China's economic planner said on Monday.The price adjustment marked the first time for the economic planner to adjust jet fuel prices on a monthly basis after it announced jet fuel pricing reforms in July, according to a notice posted on the National Development and Reform Commission (NDRC)'s website.The NDRC announced on July 7 that it would introduce a market-oriented jet fuel pricing mechanism starting from Aug. 1.Under the new mechanism, the ex-plant price of jet fuel is required to be no higher than the after-tax CIF price of jet fuel imports from Singapore, Asia's largest oil trading and storage center.Taking transportation expenses, trade volumes and international crude oil prices into account, the jet fuel premium is negotiable between jet fuel sellers and buyers and will be reviewed once a year, while jet fuel ex-plant prices will be adjusted on the first day of every month, according to the NDRC.

BEIJING, July 5 (Xinhuanet) -- Facebook CEO Mark Zuckerberg confirmed that he has signed up to Google+, the new social networking platform from Google, according to media reports Tuesday.Launched last month, Google+ is the Internet giant's latest foray into social networking.Zuckerberg confirmed that the profile with his name on Google+ belongs to him only, and said, "Why are people so surprised that I'd have a Google account?" Facebook CEO Mark Zuckerberg reacts after unveiling a new messaging system during a news conference in San Francisco, California November 15, 2010.In social networking field, it is rare for someone to join the rival's platform, therefore, Zuckerberg's move is considered strange.But interestingly, Zuckerberg has more followers than Google founders Larry Page and Sergey Brin, and even Vic Gundotra, the man behind Google+, with over 21,000 people.Besides Google+, Zuckerberg also has an account on Twitter, though it has not been updated for some time.

BERLIN, June 6 (Xinhua) -- The German authorities said on Monday that Germany's first sample tests of the allegedly contaminated bean sprouts have found no E. coli strains that have sickened more than 2,000 people in Europe.According to a statement issued by the Agriculture Ministry of the Lower-Saxony state, 23 of 40 samples concerning the suspected sprouts from a market garden in the state have tested negative, and further tests are still pending."Based on the initial findings in tests of some of the samples, especially the seeds, we assume that intensive analytical efforts are needed to prove that the suspected pathogen is really there," the statement said.Beansprouts and salad sprouts are seen in this picture illustration taken in Berlin June 6, 2011.  The German authorities said on Monday that Germany's first sample tests of the allegedly contaminated bean sprouts have found no E. coli strains that have sickened more than 2,000 people in EuropeLower-Saxony's Agriculture Minister Gert Lindemann said Sunday that a market garden in the rural district of Uelzen had provided a connection "involving all the main outbreaks" of the disease.Restaurants and food outlets of almost all E. coli-affected areas had received shipments of sprouts directly or indirectly from the company, state officials said.The German authorities have been racing to track down the source of the pathogen since the outbreak, which has infected people in 12 countries, all of whom had once traveled in northern Germany.More than 600 of those infected have developed Hemolytic Uremic Syndrome, a potentially deadly complication attacking the kidneys.The E. coli source was first thought to be cucumbers from Spain, which has caused huge loses for Spain farmers. However, this conclusion was overthrown by laboratory tests in Hamburg later.

WASHINGTON, July 13 (Xinhua) -- Human neural stem cells are capable of helping people regain learning and memory abilities lost due to radiation treatment for brain tumors, a University of California, Irvine (UCI) study suggests.Research with rats found that stem cells transplanted two days after cranial irradiation restored cognitive function, as measured in one- and four-month assessments. In contrast, irradiated rats not treated with stem cells showed no cognitive improvement."Our findings provide solid evidence that such cells can be used to reverse radiation-induced damage of healthy tissue in the brain," said Charles Limoli, a UCI radiation oncology professor.Study results will appear Friday in Cancer Research, a journal of the American Association for Cancer Research.Radiotherapy for brain tumors is limited by how well the surrounding tissue tolerates it. Patients receiving radiation at effective levels suffer varying degrees of learning and memory loss that can adversely affect their quality of life."In almost every instance, people experience severe cognitive impairment that's progressive and debilitating," Limoli said. " Pediatric cancer patients can experience a drop of up to three IQ points per year."For the UCI study, multipotent human neural stem cells were transplanted into the brains of rats that had undergone radiation treatment. They migrated throughout the hippocampus -- a region known for the growth of new neurons -- and developed into brain cells.Researchers assessed the rats one month and four months after transplantation, noting enhanced learning and memory abilities at both intervals.Additionally, they found that transplanting as few as 100,000 human neural stem cells was sufficient to improve cognition after cranial irradiation. Of cells surviving the process, about 15 percent turned into new neurons, while another 45 percent became astrocytes and oligodendrocytes -- cells that support cerebral neurons.Most notably, Limoli said, he and his colleagues discovered that about 11 percent of the engrafted cells expressed a behaviorally induced marker of learning, indicating the functional integration of those cells into memory circuits in the hippocampus."This research suggests that stem cell therapies may one day be implemented in the clinic to provide relief to patients suffering from cognitive impairments incurred as a result of their cancer treatments," Limoli said.
