Tuning in on cellular communication in the fruit fly

WORCESTER, Mass. – In their ongoing study of the processes involved in embryonic development in fruit flies, researchers at WPI's Life Sciences and Bioengineering Center at Gateway Park have identified the function of a protein that sticks out of the embryonic cell membrane like an antenna and processes signals needed for the flies' wings to develop properly.

Study calls for increased research in flu transmission to prepare for pandemic flu outbreak

PROVIDENCE, RI – Researchers at Rhode Island Hospital have completed a study to better understand the impact of infection control measures during a possible flu pandemic. Their study focused on the likelihood of the transmission of flu from individuals showing no symptoms (asymptomatic) or from individuals who are infected but have not yet exhibited symptoms. The researchers call on the scientific community to better understand the transmission of influenza in order to provide guidelines for effective pandemic flu planning.

New analysis shows liver cancer incidence has tripled since 1970s, but survival rates improving

Study Summary

A new study examining data on incidence trends, mortality rates and survival rates from the National Cancer Institute's Surveillance Epidemiology and End Results (SEER) cancer registries indicates that the incidence of liver cancer in the United States tripled between 1975 and 2005.

SCAN: Delivering bone disorder diagnosis, fracture healing

HOUSTON – (Feb. 18, 2009) – The fight against bone disorders that affect millions of Americans will soon receive a boost from an ultrasound device being developed by space biomedical researchers. The technology under development will allow early prediction of bone disorders such as osteoporosis and guided acceleration of fracture healing.

National Space Biomedical Research Institute (NSBRI) scientists are developing the technology to assist astronauts during long-duration spaceflights. Like the elderly on Earth, astronauts in space lose bone structure and quality.

'Suicide by cop' phenomenon occurring in over a third of North American shootings involving police

Pasadena, CA—February 18, 2009—"Suicide by Cop" (SBC) is a suicide method in which a person engages in actual or apparent danger to others in an attempt to get oneself killed or injured by law enforcement. A new study in the Journal of Forensic Sciences examined the prevalence of this phenomenon among a large sample of officer-involved shootings.

Investing in personalized medicine will benefit Canada

Canada has the opportunity to be an international leader in personalized medicine and needs to invest in this area for the health of Canadians and to reap the benefits of job creation, writes Dr. Thomas Hudson in a commentary http://www.cmaj.ca/cgi/rapidpdf/cmaj.1090199 released online today in CMAJ (Canadian Medical Association Journal).

New genomic markers associated with risk of heart disease and early heart attack

Five short reports published simultaneously by the journal Nature Genetics have for the first time identified clusters of genetic markers associated with heart attack and coronary heart disease. In one of the reports, from the largest ever study of its kind, the Myocardial Infarction Genetics Consortium identified nine precise genes associated with an increased risk of infarction (MI), three of them newly discovered; the investigators said that these nine gene variants "identify 20% of the population at 2.25-fold increased risk for MI".

Research increases possibilities of personalizing treatment of infant osteosarcoma

A team of specialists at the University Hospital of Navarra have revealed the existence of genetic variants that have greater resistance to a specific treatment and a greater toxicity of the pharmaceutical drug in some child patients affected by osteosarcoma. The team investigated the mechanisms of the illness in order to obtain a personalised therapeutic treatment in the future.

TB treatment delays in Taiwan

Older people suffer delayed tuberculosis treatment. A Taiwanese study of 78,118 pulmonary tuberculosis (PTB) cases, reported in the open access journal BMC Public Health has found that older people had both diagnosis and treatment delays in tuberculosis and those with an aboriginal background had a longer treatment delay.

Cheaper materials could be key to low-cost solar cells

Berkeley -- Unconventional solar cell materials that are as abundant but much less costly than silicon and other semiconductors in use today could substantially reduce the cost of solar photovoltaics, according to a new study from the Energy and Resources Group and the Department of Chemistry at the University of California, Berkeley, and the Lawrence Berkeley National Laboratory (LBNL).

These materials, some of which are highly abundant, could expand the potential for solar cells to become a globally significant source of low-carbon energy, the study authors said.

Gene mutation increases drug toxicity, rejection risk in pediatric kidney transplants

CINCINNATI – Screening for mutations in a gene that helps the body metabolize a kidney transplant anti-rejection drug may predict which children are at higher risk for side effects, including compromised white blood cell count or organ rejection, according to new research.

Statins pay off on a health-policy level, UCSF study finds

Current guidelines for when to prescribe popular cholesterol-lowering drugs called statins would produce cost-effective results and would save thousands of lives every year if they were followed more closely by physicians and patients, according to a new study led by researchers at the University of California, San Francisco.

States expand newborn screening for life-threatening disorders

WHITE PLAINS, N.Y., FEB. 18, 2009 – Regardless of where they are born in the United States, nearly all newborns now receive mandated screening for many life-threatening disorders, a remarkable public health advance of the last four years, according to a new report issued today by the March of Dimes.

Cancer death rates dropping among African Americans but survival rates still low

ATLANTA– February 18, 2009 – While death rates from cancer continue to drop among African Americans, the group continues to be diagnosed at more advanced stages and have lower survival rates at each stage of diagnosis compared to whites for most cancer sites. The findings come from Cancer Facts & Figures for African Americans 2009-2010, the latest edition of a report produced every two years by the American Cancer Society, the nation's leading voluntary health organization.
