BEIJING, March 17 (Xinhuanet) -- A new study has shown that gene therapy can reduce symptoms in patients with Parkinson's, media reports said Thursday.The study, published in the journal Lancet Neurology, is the first to show positive results in a test of gene therapy against a sham operation in 45 U.S. Parkinson's patients.The treated group showed a 23.1 percent improvement on a scale of Parkinson's symptoms six months after treatment, compared to a 12.7 percent improvement for patients who received sham surgery, according to the published research."Gene therapy is no longer just a theory," said Michael Kaplitt, a neurosurgeon at New York-Presbyterian Hospital and Weill Cornell Medical Center, and one of the study authors. "We are getting much closer to a reality where this treatment can be offered to patients."In patients with Parkinson's disease, their brains get overactive after losing the normal supply of a chemical called GABA. The new treatment, gene therapy, works by inserting billions of copies of a gene into patients' brains that helps them produce more GABA.Kaplitt said the results might spur similar treatments for other brain disorders like Alzheimer's, epilepsy and depression.

ACCRA, Feb. 12 (Xinhua) -- China would in the coming years inject more capital to support the infrastructure needs of Ghana, Chinese Ambassador to Ghana Gong Jianzhong has said.Briefing the media here on Friday night to announce the visit to Ghana by Chen Deming, the Chinese Minister of Commerce, Ambassador Gong said that China is willing to join in the infrastructure development of Ghana."We are willing to join Ghana in improving its infrastructure base. We will be happy to give our contribution towards the infrastructure development of Ghana," he said.The forthcoming two-day visit by the Chinese minister would afford the two countries to further cement, promote and syncretize the bilateral trade and economic corporation existing between them for more than five decades.The ambassador said the Chinese Embassy in Ghana is committed to offering quality service to Ghanaians engaging in bilateral exchanges and cooperation in different fields.Currently, China has supported the West African country in the construction of various roads, rails, school blocks, hospitals, among others.He called on the Chinese firms in Ghana to raise investments and take corporate social responsibilities in local communities where they are operating.

JERUSALEM, May 8 (Xinhua) -- Israeli researcher Jacob (Koby) Scheuer, from the Tel Aviv University (TAU) School of Electrical Engineering, has developed a nano-scale gyroscope, the Ha'aretz daily reported Sunday.Scheuer developed a new optic-fiber nano-sensor four years ago, along with an optic gyroscope that works in conjunction with the sensor. As he developed the devices, it occurred to him that his discovery could be harnessed to surgical needs, virtual reality, or communications, said the report."What we developed here is an optic gyroscope," Scheuer told Xinhua in a recent interview on Sunday, "like the others, but the breakthrough is that we found a way to measure rotation in a very, very small device using the optic sensor."Optic gyroscopes emit light when they rotate, and change its wavelength when there is any change in the speed of rotation, making it possible to measure velocity and position by the differences in light.Scheuer's gyroscope, however, is so small in comparison to the others commonly used in planes, trains and vehicles, that it can be used in cell phones or watches and does not need satellite connection like the ubiquitous Global Positioning System.The applications of this gyroscope and optic sensor are almost endless, as Scheuer puts it."It can be a pill that you swallow and can move through your body to take pictures or release drugs in a localized area," the researcher explained, "or it can be used by a doctor to operate on a patient who is thousands of kilometers away.""Our gyroscope has complete independent navigation capability, which the others don't have," he stressed.Though the new optic gyroscope works in theory, it still hasn't been tried in out in reality. "It will take some time until we can empirically demonstrate our work, I would say about three to five years," Scheuer added.Alongside the gyroscope, Scheuer continues to work on the optic sensor, whose applications can also be found in security, such as an information security system developed by Scheuer to safeguard online information that acts as a key bearer."When both parties have 'the key' it's virtually impossible to hack the information sent," Scheuer noted, terming the development as a "total paradigm change."

SAN FRANCISCO, March 29 (Xinhua) -- Computer networking equipment giant Cisco Systems Inc. on Tuesday announced the intent to buy privately-held software company newScale Inc., in a move to complement and expand its offerings in cloud computing.Based in San Mateo in the U.S. state of California, newScale provides software that delivers a service catalog and self-service portal for information technology (IT) organizations to select and quickly deploy cloud services within their businesses.Founded in 1999, the company now has more than two million users worldwide, including 20 percent of the Fortune 50 companies, according to information posted on newScale's website."With the acquisition of newScale, Cisco will be able to accelerate the deployment of cloud services through a service catalog and self-service portal that allows customers to easily manage their IT infrastructures," Parvesh Sethi, Cisco's senior vice president, noted in a statement.Cisco said it expects to close the deal in the second half of its fiscal year 2011, without disclosing financial terms.

SAN FRANCISCO, April 8 (Xinhua) -- YouTube on Friday launched YouTube Live, a homepage for live content on the site and a new live-streaming platform.As part of the service, the world's largest video-sharing website introduced a new browse page, www.youtube.com/live, where users can view live events and add upcoming events to their calendars.YouTube said it would gradually roll out a live streaming beta platform, which will allow certain YouTube partners with accounts to stream live content on the website.The new service will "integrate live streaming capabilities and discovery tools directly into the YouTube platform for the first time," YouTube said in a blog post.U.S. media recently reported that YouTube is planning a major overhaul and is negotiating with Hollywood and music producers for materials to offer on a lineup of new channels, with the aim to compete with broadcast and cable television.
