Childhood Radiation Therapy Increases Future Breast Cancer Risk, Study Finds
Women who underwent radiation therapy for cancer as children have an increased long-term risk for developing breast cancer, according to a study published in the Journal of Clinical Oncology, Reuters reports. However, when the childhood treatments included a high dose of radiation to the ovaries, women"s risk of developing future breast tumors was "sharply reduced," according to the study.For the study, Peter Inskip of the National Cancer Institute and colleagues examined 120 women diagnosed with cancer before age 21. All women in the study were treated with radiation between 1970 and 1986 and survived at least five years. The women were compared with four women who also were diagnosed at a young age but did not receive radiation.The study found that the more radiation a woman received as a child, the more likely it was that a tumor would eventually develop. The study did not find that chemotherapy for the first cancer increased the risk for a second cancer (Reuters, 7/20).

'Taking Up A Dialogue' With The Brain: Letter Decoding From Single-trial Brain Signals
Brain-computer interfaces "translate" what a person is thinking in words or actions. Researchers from Maastricht University in the Netherlands performed functional MRI brain scans on healthy participants, instructing them to "type" by performing mental tasks corresponding to different letters in the English alphabet. Researchers were able to use signals from the participants" brain activation patterns to decode information about the intended letter that a participant was thinking about, and to use this in a conversation with the experimenters without any spoken words. It is hoped that such technology can enable communication with "locked-in" patients or assessment of consciousness in non-responsive patients.

146th Annual AVMA Convention In Seattle Invites Veterinarians To Help Clean Up Animal Shelters

Veterinarians will be giving back to the city of Seattle during the 146th American Veterinary Medical Association (AVMA) Annual Convention - held from July 11-14, 2009, in Seattle, Wash. - by helping fix up two animal shelters and a horse rescue facility. The event will be funded and overseen by the American Veterinary Medical Foundation (AVMF), the charitable arm of the AVMA. This will be only the second volunteerism program - known as Our Oath in Action: AVMF Voluntourism - during an AVMA convention. Last year, the AVMA convention was held in New Orleans, and veterinarians decided to pitch in to paint and repair three local shelters damaged by Hurricane Katrina. The program was such a success - well received by both conventioneers and the community - that the association will repeat it in Seattle. "We wanted to be a part of the cleanup efforts in New Orleans following Hurricane Katrina, and so that"s why we started this great program," explains Dr. Bruce Little, coordinator for the Our Oath in Action project. "Volunteering time at these shelters was so rewarding for everyone involved that we decided that it couldn"t end in New Orleans. The Oath in Action program offers just two things, compassion and labor, and if we can utilize those two res to help repair and refurbish shelters, then this program will be a great success." This year"s cleanup efforts will take place on July 10 and 11, putting conventioneers to work just as they arrive for the AVMA"s 146th Annual Convention. More than 200 conventioneers will volunteer their time to paint a barn and animal shelters, build fences, relocate and rebuild a storage barn, prepare and wash cats and dogs for an adoption event, clean up kennels and outdoor exercise yards, and do what they do better than anyone else - work with animals. "The Foundation is delighted to embrace these three shelters in Seattle, as our mission is all about promoting the health and welfare of animals," explains Michael Cathey, director of the AVMF. "If you are unable to attend and participate in this year"s Our Oath in Action event, and you would still like to help in this effort or in any of the important charitable projects that the Foundation undertakes, please contact us." The three shelters that will receive this labor include: - Hope For Horses: 12518 238th St. SE, Snohomish, Wash - King County Animal Care: 21615 64th Ave. S, Kent, Wash. - Seattle Animal Shelter: 2061 15th Ave. W, Seattle, Wash The Our Oath in Action Program is sponsored by Bayer Animal Health and Hills Pet Nutrition, which will be providing t-shirts, breakfast, lunch and transportation for volunteers during the event.
