Half of prostate cancers could potentially benefit from new type of cancer drugs, U-M study finds

ANN ARBOR, Mich. — About half of prostate cancers have a genetic anomaly that appears to make tumor cells responsive to a new class of cancer-fighting drugs, a new study from the University of Michigan Comprehensive Cancer Center finds.

The drugs, called PARP inhibitors, are currently being tested in breast cancer patients with mutations in the BRCA1 and BRCA2 genes, which are found in up to 10 percent of all breast cancers.

Increase in risk of certain gastric cancer from heavy drinking

The results from a very well-done meta-analysis support other data generated on the risk of alcohol consumption and gastric cancer – that is – that the risk may be real for heavy alcohol consumption but not for moderate intake. The type of gastric cancer relating to heavier alcohol intake in this study tended to be tumors involving the noncardia, but differences between the association with tumors of the gastric cardia were not significant.

Marker identifies breast cancer patients likely to respond to tamoxifen

PHILADELPHIA—Cancer researchers at the Kimmel Cancer Center at Jefferson and an international team of collaborators have discovered a biomarker in breast cancer that may help identify which women will respond to anti-estrogen therapy.

The research appears in the May 16 online issue of the Journal of Clinical Oncology.

It's not easy being green

LA JOLLA, CA—The seeds sprouting in your spring garden may still be struggling to reach the sun. If so, they are consuming a finite energy pack contained within each seed. Once those resources are depleted, the plant cell nucleus must be ready to switch on a "green" photosynthetic program. Researchers at the Salk Institute for Biological Studies recently showed a new way that those signals are relayed.

Scientists discover switch to speed up stem cell production

A team of scientists from Genome Institute of Singapore (GIS) of the Agency for Science, Technology and Research (A*STAR) have shown how proteins involved in controlling genes work together to carry out their functions in stem cells and demonstrated for the very first time, how they can change interaction partners to make other types of cells.

Hospitals misleading patients about benefits of robotic surgery, study suggests

An estimated four in 10 hospital websites in the United States publicize the use of robotic surgery, with the lion's share touting its clinical superiority despite a lack of scientific evidence that robotic surgery is any better than conventional operations, a new Johns Hopkins study finds.

The promotional materials, researchers report online in the Journal for Healthcare Quality, overestimate the benefits of surgical robots, largely ignore the risks and are strongly influenced by the product's manufacturer.

High pregnancy weight gain can lead to long-term obesity

Gaining more than the recommended weight during pregnancy can put women at increased risk of becoming obese and developing related health problems, including high blood pressure, later in life.

These are the latest findings from researchers at the Avon Longitudinal Study of Parents and Children (ALSPAC)/Children of the 90s at the University of Bristol.

Radiation protection expert criticizes comparison of Fukushima to Chernobyl

In the opening editorial to the latest edition of the Journal of Radiological Protection, published today, Wednesday 18 May, radiological protection expert Professor Richard Wakeford of the Dalton Nuclear Institute, The University of Manchester, gives a detailed account of events at Fukushima Dai-ichi Nuclear Power Station, and poses several questions that remain unanswered, several weeks on from the earthquake and tsunami on 11 March.

Breaking the silence on aid workers' salaries

A new international Task Force has been set up to promote 'a fair day's work for a fair day's pay' for workers and to develop organisational capacity in lower income countries. The research which found discrepancies between the salaries earned by local and those earned by expatriate aid workers was instrumental in setting up the task force.

Artificial tissue promotes skin growth in wounds

ITHACA, N.Y. - Victims of third-degree burns and other traumatic injuries endure pain, disfigurement, invasive surgeries and a long time waiting for skin to grow back. Improved tissue grafts designed by Cornell scientists that promote vascular growth could hasten healing, encourage healthy skin to invade the wounded area and reduce the need for surgeries.

Potentially toxic flame retardants detected in baby products

Scientists are reporting detection of potentially toxic flame retardants in car seats, bassinet mattresses, nursing pillows, high chairs, strollers, and other products that contain polyurethane foam and are designed for newborns, infants and toddlers. In a study in ACS' journal Environmental Science & Technology, they describe hints that one flame retardant, banned years ago in some areas, actually remains in use. "To the authors knowledge, this is the first study to report on flame retardants in baby products," the report states.

Birch bark brings metabolic benefits

An ingredient found in abundance in birch bark appears to have an array of metabolic benefits, according to new studies in animals that are reported in the January issue of Cell Metabolism, a Cell Press publication. In mice, the compound known as betulin lowered cholesterol, helped prevent diet-induced obesity, and improved insulin sensitivity. Betulin-treated mice were also more resistant to developing atherosclerotic plaques in their arteries.

CSI: Infection

Every 30 seconds, infectious diseases such as malaria, HIV/AIDS and tuberculosis kill as many people as Jack the Ripper did in his entire career. New research published in BioMed Central's open access journal International Journal of Health Geographics demonstrates how the mathematical model of geographic profiling, used in the hunt for serial killers, can help combat infectious diseases.

Too posh to push? The increasing trend for cesarean section

During the last thirty years there has been an increase in the number of babies born by Caesarean section. New research published in BioMed Central's open access journal BMC Public Health shows that there has also been a change in the social and economic status of the mothers involved and that advantaged mothers are more likely to have their babies by Caesarean section than mothers living in more difficult circumstances.

Staff-prisoner relationships are key to prison quality

As public sector prisons move towards the thin staffing level model of profit-making institutions, with their high turnover of personnel who are less connected to their occupation, a study funded by the Economic and Social Research Council (ESRC) warns of a potentially detrimental impact on prison quality.
