Two thousand influenza virus genomes and counting…
The entire genetic blueprints of more than 2,000 human and avian influenza viruses taken from samples around the world have now been completed. The sequences will help scientists understand how influenza viruses evolve and spread, and will aid in the development of new flu vaccines, therapies and diagnostics.
Increasing protein level rescues hearing in deaf mice
A new study in mice gives insight into the cause behind many cases of deafness and suggests new therapeutic approaches to combating hearing loss. more
Compounds show promise against potential bioterror agent
Botulism is a rare but serious illness that causes paralysis and can be fatal. It’s caused by nerve toxins made by the bacterium Clostridium botulinum. “Type A” toxin is so deadly and easy to produce that the U.S. Centers for Disease Control and Prevention (CDC) considers it one of the highest-risk agents for bioterrorism. In a new study, researchers have identified two small molecules that could prove to be ideal countermeasures for a bioterror attack using botulinum toxin A. more
Study estimates overall HPV prevalence in U.S. women
Data from the National Health and Nutrition Examination Survey (NHANES) published in the February 28 Journal of the American Medical Association (JAMA) have provided the first national estimate of the prevalence of human papillomavirus (HPV) infection among women in the United States aged 14 to 59. Investigators found that a total of 26.8 percent of women overall tested positive for one or more strains of HPV. more
Children often develop fragile bones from cancer and its treatment
Research suggests that children treated for cancer are at greater risk years later for bone problems such as osteoporosis and fractures. An article in the April 1 issue of Cancer marshals evidence from a variety of studies and sources, leading its authors to conclude that "loss of bone mineral is clearly a common consequence of the treatment of cancer in children and adolescents."
Strenuous long-term physical activity lowers risk of breast cancer
California researchers have found that strenuous long-term physical activity decreases a woman's risk of invasive and in situ breast cancer, according to study results published in the February 26 Archives of Internal Medicine. more
Radiation and chemo before esophageal cancer surgery improves survival
A significant survival benefit was evident for the preoperative (neoadjuvant) use of combination chemoradiotherapy and, to a lesser extent, for chemotherapy alone in patients with localized esophageal cancer in a meta-analysis of data from numerous clinical trials that was published online February 15 in Lancet Oncology. more
