Effective cancer treatments follow the clock
Oncologists have long thought that cancer treatments tend to be more effective at certain times of day. But they have been unable to turn this knowledge into practice, because they did not understand the phenomenon well enough. Now, researchers have discovered a molecular mechanism that explains why sensitivity to anti-cancer drugs changes with the clock. They said their findings could lead to new drug treatments that may be more effective because they harness the power and precision of the body's internal clock.  more

Emergency department study supports giving dehydrated children fluids by mouth
Oral rehydration therapy, or giving fluids by mouth, is equally effective as giving intravenous fluids to young children dehydrated by common stomach and intestinal inflammations, according to a new study by emergency medicine physicians. Because oral therapy can be started more quickly and is less painful for the child than IV treatment, the researchers say it should be the preferred treatment for children with moderate dehydration.  more

PET/MRI scans may help unravel mechanisms of prenatal drug damage
Scientists have demonstrated a new way to assess the potentially damaging effects of prenatal drug exposure--a technique that could also be used to monitor a fetus's response to therapeutic drugs--using sophisticated, noninvasive medical imaging tools.  more

Stat5 protein inhibits spread of breast cancer cells
The presence of a protein known as Stat5 prevents laboratory-grown breast cancer cells from becoming invasive and aggressive, according to new research from Georgetown University. The research, which appears in the 27 January issue of Oncogene, could one day lead to advanced therapies for breast cancer patients. more
