Proteomics: Finding The Key Ingredients Of Disease
The winner of the chilli cook-off, usually has a key secret ingredient, which is hard to identify. Similarly, many diseases have crucial proteins, which change the dynamics of cells from benign to deadly. New findings from an international collaboration, involving McGill University, the Research Institute of the McGill University Health Centre (MUHC) and the Human Proteome Organisation (HUPO) just made identifying these changes one step easier. Their findings published in Nature Methods, show how to improve protein analysis to tease out relevant potential disease-causing molecules.

Low Vitamin D Levels In Blacks Could Contribute To Higher Rates Of Cancer, Other Diseases, Researcher Says
Low vitamin D levels in blacks could contribute to health gaps between white and black U.S. residents, Michael Holick, a professor at Boston University and a vitamin D researcher, said recently, the GNS/Chicago Sun-Times reports. According to Holick, blacks have lower levels of vitamin D than whites in part because the higher amount of pigment in their skin makes it harder for their body to absorb the nutrient, which is produced in response to sun exposure. Although scientists are debating optimum vitamin D levels, some scientists have said that vitamin D can reduce the risk of cancer, diabetes, heart disease and other illnesses. Holick added that some scientists believe blacks are more likely to have prostate cancer, breast cancer and colon cancer and have more aggressive forms of the cancer because they have lower levels of vitamin D. John Flack, principal investigator at the Center for Urban and African American Health at Wayne State University, said lower vitamin D levels among blacks is "potentially a very important explanation for some of the differences, from hypertension to cancer to heart failure," adding, "The actual proof is not there, but it"s plausible." Flack added that many factors -- including decreased access to health care and differences in income and education -- contribute to the overall poorer health among blacks. The Institute of Medicine next year is expected to release new guidelines on recommended daily intake for vitamin D. "All Americans, but particularly people with darker skin, should pay attention" to the new guidelines, according to Adit Ginde, a researcher at the University of Colorado Denver School of Medicine who led a recent study that found vitamin D levels are decreasing in all racial groups and are particularly low in blacks (Painter, GNS/Chicago Sun-Times, 5/28).

150 Days: Obama's Silence On AIDS Remains Deafening

On the observation of President Obama"s first 150 days in office, AIDS Healthcare Foundation (AHF), the nation"s largest AIDS organization, is continuing its "Change AIDS Obama" campaign with the release of a new online advocacy video chastising the president for his ongoing-and baffling-silence on AIDS. "AHF"s latest video, "150 Days and Counting" marks AHF"s disappointment with President Obama"s ongoing silence on AIDS," said Michael Weinstein, AHF"s President. "This ad is another element in our campaign to raise awareness about the President"s steadfast aversion to addressing or even mentioning the word AIDS throughout his first six months in office. With this ad, we hope to spur President Obama to act on AIDS, and to also encourage the public at large to visit our changeAIDSobama.org website, learn more about the President"s glaring inaction on AIDS, write to the White House to demand action, and join our site to follow our pursuit of the issue." The "150 Days and Counting" video features photos of the President with the following text slates slowly dissolving over his image: - President Obama your silence on AIDS is deafening - 150 days and counting - 6,000 deaths a day - Silence = death - http://www.changeAIDSobama.org Previous Elements of the http://www.changeAIDSobama.org campaign Previous elements in the campaign include AHF"s "AIDS is DC"s Katrina" bus shelter ads now appearing throughout Washington, D.C. The provocative ad contrasts an iconic photo of an indifferent George W. Bush looking out the window of Air Force One at the devastation and aftermath of Hurricane Katrina in New Orleans with a close up photo of a seemingly homeless person"s pair of hands holding tightly onto a piece of a battered corrugated cardboard with the phrase, "AIDS is DC"s Katrina" scrawled in red across the cardboard. This is part of AHF"s "Change AIDS Obama" campaign designed to prod President Obama to act forcefully on AIDS. Other aspects of the campaign include several thought-provoking viral videos, an ongoing eLetter-writing campaign and an interactive website: http://www.changeAIDSobama.org. "Part of the intent of the "Change AIDS Obama" campaign was to remind President Obama that he need not go further than his own backyard to witness the nation"s worsening HIV/AIDS epidemic and the failure of U.S. HIV prevention efforts," added AHF"s Weinstein. "AHF produced the print ad and companion viral video after the recent revelation that the HIV prevalence rate in Washington surged past 3%-higher than the rate found in Lagos, Nigeria. Though the President has so far been silent on AIDS, we remain hopeful that he and his administration will be the change we can believe in on AIDS." The "150 Days and Counting" video as well as previous items in the campaign can be viewed at: http://www.changeAIDSobama.org AIDS Healthcare Foundation (AHF)
