WASHINGTON, April 6 (Xinhua) -- A study led by researchers at the University of Michigan (U-M) showed in animal studies that new cancer drug compounds they developed shrank tumors, with few side effects.The study, done in two mouse models of human cancer, looked at two compounds designed to activate a protein that kills cancer cells. The protein, p53, is inactivated in a significant number of human cancers. In some cases, it is because another protein, MDM2, binds to p53 and blocks its tumor suppresser function. This allows the tumor to grow unchecked. The new compounds block MDM2 from binding to p53, consequently activating p53."For the first time, we showed that activation of p53 by our highly potent and optimized MDM2 inhibitors can achieve complete tumor regression in a mouse model of human cancer," says lead study author Shaomeng Wang, director of the Cancer Drug Discovery Program at the U-M Comprehensive Cancer Center.Wang presented the study Wednesday at the American Association for Cancer Research 102nd annual meeting.Many traditional cancer drugs also activate p53 but they do so by causing DNA damage in both tumor cells and normal cells, causing side effects. These new MDM2 inhibitors activate p53 while avoiding the DNA damage common with other drugs. In this study, which was done in collaboration with Ascenta Therapeutics and Sanonfi-Aventis, researchers showed that these new drugs shrank tumors without significant side effects.Because p53 is involved in all types of human cancer, the new drug has potential to be used in multiple types of cancer. Further, the researchers also identified certain markers in tumors that predict which ones will be particularly sensitive to the MDM2 inhibitor, which would allow physicians to target the drug only to patients most likely to benefit.

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.

BEIJING, March 21 (Xinhuanet) -- A new device is being developed by American engineers to ease pain of blood sugar testing in diabetics, according to foreign media report last week.The upcoming device is the research target of a team of engineers at Arizona State University. It is specifically designed for patients with type1diabetes and type2 diabetes, according to a report in the "Journal of Diabetes Science and Technology,"  The traditional method of testing blood sugar levels involves painful pricks on the fingers to draw blood for testing. The inconvenient and painful process may somehow leave diabetics lax in their testing. The blood sugar levels, when poorly controlled, are very likely to trigger complications including heart disease, kidney disease and retinopathy.Unlike the old testing method, the new device could help people keep track of their blood sugar levels without the need to break the skin. It draws tears to measures the blood sugar levels in the fluid and gives just an accurate reading of blood sugar levels. "This new technology might encourage patients to check their blood sugars more often, which could lead to better control of their diabetes by a simple touch to the eye." said Jeffrey T. LaBelle, developer of the device.The new testing device has drawn great interest from investors due to its promising prospects. However, it still awaits a significant amount of testing before it can hit the market.

KIGALI, Feb. 8 (Xinhua) -- Li Zhaozhuo, vice chairman of the National Committee of the Chinese People's Political Consultative Conference (CPPCC), will head a high-level delegation to Rwanda this month to boost friendly and cooperative ties between the two countries.According to a statement released by Rwanda's Senate on Tuesday, the three-day visit will begin on Feb. 18 and is to strengthen regular contacts between Rwandan and Chinese parliamentary chambers on a number of issues and review bilateral projects.Chinese Ambassador to Rwanda Shu Zhan has confirmed that the official delegation from China is "planning an outreach visit" to Rwanda.After a meeting with the Chinese envoy to Rwanda on Tuesday, the president of Rwanda's Senate, Vincent Biruta, said his country's legislative chambers would continue to promote friendly ties with the CPPCC and play a "constructive role" in promoting bilateral cooperation.Rwanda have received training assistance from China in the applications of information communication technology (ICT) in parliaments.The Central African nation has a long-standing bilateral relationship with China in a number of socio-economic areas such as infrastructure, energy, education, health, agriculture and communications.
