A New Take On Growth Factor Signaling In Tamoxifen Resistance
Differences in growth factor (GF) signaling may cause the poor prognosis in some breast cancer cases. A new study, published in the open access journal BMC Medical Genomics, suggests that some estrogen receptor-positive breast cancers respond poorly to tamoxifen because of increased GF signaling.

Vietnamese HIV/AIDS Department Announces Funding For Prevention Efforts
Vietnamese officials announced recently that about 678 billion dong, or about $38.7 million, will be allocated for HIV/AIDS prevention efforts in the country in 2009, the VNA/VietnamPlus.com reports. The announcement was made during a press briefing earlier this week held by the Department for HIV/AIDS Prevention and the Vietnam Journalists Association to review Vietnam"s HIV/AIDS efforts in 2008. Health officials at the briefing said that more than 27,000 people living with HIV/AIDS received treatment through one of the 207 district-level clinics put in place last year and that about 6,000 peer educators and health workers distributed information about the disease to 53.8% of the country"s districts.The new funding will help provide antiretroviral treatment to an estimated 32,000 people living with HIV/AIDS. It also will be used to provide post-exposure prophylaxis to health workers. In addition, the funding will allow up to 90% of HIV-positive pregnant women to receive antiretroviral treatment and information about preventing mother-to-child transmission. Last year, 20,260 new HIV cases were reported in Vietnam, of which 7,452 had progressed to AIDS, according to the HIV/AIDS department. The city of Ho Chi Minh reported the largest number of HIV cases with more than 34,000, accounting for more than 25% of the total number of cases in Vietnam (VNA/VietnamPlus.com, 5/12).

A Vaccine For Ear Infections - Without The Needle

Even when she"s well, little Cammy Barber doesn"t like getting her ears checked - and for good reason. She"s only nine months old and has already had eight ear infections. And her mom, Coleen Barber, will tell you, treating them isn"t always easy. "The shots are awful to see the child have to get, but even the medicine alone, they don"t like the flavor of it, at this age, it"s hard to sneak it into anything," says Coleen. So scientists at Nationwide Children"s Hospital are working on an Alternative involving just a single drop of liquid. A drop that"s not injected or even swallowed, but simply rubbed onto the outside of the ear. And best of all, it"s a vaccine designed to stop ear infections before they ever start. Experts say it could someday help kids everywhere, especially those with no other alternatives. And lab test are promising. "It was extremely effective. So we"re very excited about the ability to maybe immunize without needles and deliver this vaccine to the poorest children in the world," says Lauren Bakaletz, PhD, a researcher at Nationwide Children"s hospital who developed the vaccine. Dr. Bakaletz says it works by activating cells just under the surface of the skin, called dendritic cells. When this liquid touches the skin, it touches off a response throughout the body. "These cells deliver it to the lymphoid organs where it can generate an immune response. So really harnessing a power that"s there all the time, but you"re doing it in a way that"s now directed toward a specific disease," says Dr. Bakaletz. Dr. Bakaletz, who is also with the Ohio State University, says work still needs to be done before the vaccine is tested on kids - but if someday could help babies like Cammy live more care-free, pain-free lives. It is estimated that 83% of all kids get ear infections before their third birthday** and another child gets an ear infection every 2.3 seconds in this country.* In fact, it is the number one reason kids are taken to the emergency department.** *New Vaccines Against Otitis MEdia: Projected Benefits and Cost-effectiveness, Pediatrics, Vol. 123 No. 6, June 2009, retrieved from: http://pediatrics.aappublications.org/cgi/content/abstract/123/6/1452 ** A Novel Transcutaneous Immunization Regimen Elicits a Mucosal and Systemic Immune Response That Confers Protection Against Nontypeable Haemophilus Influenzae-induced Otitis Media, Laura Novotny, Lauren Bakaletz, The Research Institute at Nationwide Children"s Hospital, presented at the American Society of Microbiology General Meeting, May 2009 Nationwide Children"s Hospital
