LOS ANGELES, May 29 (Xinhua) -- Nineteen percent of

KAMPALA, May 14 (Xinhua) -- The deadly Ebola hemorrhagic fever has broken out in Uganda, killing one person and leaving over 30 others being monitored by health officials, ministry of health announced here on Saturday.The epicenter of the outbreak is in the central Ugandan district of Luwero located about 50 km north of the capital Kampala.According to Anthony Mbonye, head of the community health department at the ministry of health, a 12 year old girl in Zirombwe Sub-county developed symptoms of Ebola and when she was admitted at a military hospital in the district, laboratory test confirmed that it was Ebola.The Ebola virus is highly contagious and causes a range of symptoms including fever, vomiting, diarrhea, generalized pain or malaise and in many cases internal and external bleeding.The girl died on May 6 and about 30 people who she got contact with are being asked to not get into contact with the public as health officials monitor them for about 21 days.The 30 people have not yet developed the symptoms but if they do, they will be isolated from the public.Mbonye said that preliminary investigations have showed that this Ebola virus is similar to the one that broke out in Sudan, thus named Sudan Ebola.The epicenter of the outbreak is also located along the high way to southern Sudan.This viral subtype has a human case fatality rate of 60 percent meaning that it will kill 60 percent of the infected people.The other subtype is the Congo Ebola which also attacked Uganda in 2007. This one has a human case fatality rate of over 80 percent.The 2007 outbreak which occurred in the western district of Bundibugyo bordering eastern Democratic Republic of Congo claimed 37 lives out of the 148 infected.Mbonye said that there also ongoing investigations to find out whether the index case got into contact with moneys or bats, the known reservoirs of the Ebola virus.Following the outbreak, government has reactivated the National Ebola Task Force (NETF) to coordinate the fight against the disease at the national level.District task forces are also in the process of being formed according to Mbonye, who is the chairperson of the NETF.

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.

JOHANNESBURG, March 23 (Xinhua) -- Cervical cancer ranks as the second most frequent cancer among women in South Africa.Recent information from a World Health Organization (WHO) and ICO Information Center on Human Papilloma virus (HPV) and Cervical Cancer 2010 report shows that 16.84 million South African women aged 15 years and older are at risk of developing cervical cancer.Current estimates indicate that every year 5,743 women are diagnosed with cervical cancer and more than 3,000 die from the disease.About 21 percent of women in the general South African population are estimated to harbor cervical HPV infection at any given time, and 62.8 percent of invasive cervical cancers are attributed to HPV subtypes 16 or 18."Concern is growing as there appears to be an increasing epidemic of papillomavirus-induced disease involving not only the cervix but elsewhere in the female genital tract and anogenital region," said Professor Martin Hale, head of the Department of Anatomical Pathology at the University of the Witwatersrand (Wits) in Johannesburg and the National Health Laboratory Service.The South African population and people from Africa in general have high incidences of the HPV subtypes 16 or 18 according to Professor Hale. He is not entirely sure why but is of the opinion that the infection rate can be lowered."The common theory is that HPV is transmitted through sexual intercourse. If treated like a sexual disease and the necessary precautions are taken during sex the infection rate can be lowered, " Hale told Xinhua in an interview on Wednesday.HPV is also exacerbated as a result of the HIV pandemic and cause a rapid progression of premalignant dysplasia to invasive cancer in HIV positive patients.Hale believes the limited access to information and resources make it easy for the condition to thrive.However, according to Hale, a debate is still raging on how, to whom and whether the vaccine should be administered.Black women are at higher risk of contracting HPV and subsequent cervical cancer. Other risk factors that increase susceptibility include age of first intercourse, the number of children per woman, and a weakened immune system, to name a few."To avoid getting cervical cancer get the vaccine against HPV 16 and 18 infection before starting to be sexually active, have protected sex and go for regular screenings," he told Xinhua.

BEIJING, May 24 (Xinhuanet) -- Facebook founder Mark Zuckerberg welcomed more kids to join in the social network site, according to International Business Times reports on Monday.He made this comment in the NewSchools Summit in California.Zuckerberg said Facebood can help young kids to learn from each other and acquire more knowledge about using the internet."That will be a fight we take on at some point," Zuckerberg said, "My philosophy is that for education you need to start at a really, really young age." At the moment, Facebook officially does not allow the children younger than 13 to sign up, since the Children's Online Privacy Protection Act (COPPA) forbids children under 13 from joining an online service which collects user information data.However it recently revealed that 7.5 million Facebook users were younger than that, accoding to a study released last week by Consumer Reports.Some experts suggested Facebook may not be in any position to provide that education in its current form. "The lessons of digital citizenship have to start young, but I don't feel that Facebook is the venue to have those lessons occur. A lot of missteps happen on that site without a lot of coaching." said Dr. Gwenn O'Keeffe, an expert on young children's education.
