Advanced lung cancer patients see improved, progression-free survival

Patients with advanced non-small cell lung cancer whose disease has progressed following chemotherapy have a higher rate of tumor shrinkage and a longer interval before cancer progression when bevacizumab is added to standard second-line erlotinib therapy, according to a study presented at the 2008 Chicago Multidisciplinary Symposium in Thoracic Oncology, sponsored by ASTRO, ASCO, IASLC and the University of Chicago.

Osteoporosis drugs may prevent future bone growth

Patients who start and eventually stop regimens of a common class of osteoporosis drugs called bisphosphonates may be unable to benefit from parathyroid hormone (PTH), which can rebuild bone mass lost due to advanced stage osteoporosis. PTH has been proven to increase the volume and strength of the honeycomb-like bone infrastructure, the inner mesh that begins to diminish in old age.

Hope for treating relapse to methamphetamine abuse

"Reinstatement of drug-seeking behavior after an extended period of abstinence is the number-one cause of drug-addiction relapse," said Brookhaven neuroanatomist Stephen Dewey, who led the research team. "This animal study suggests that vigabatrin could potentially prevent human methamphetamine addicts from relapsing."

Breakthrough in cell-type analysis offers new ways to study development and disease

Like skilled assassins, many diseases seem to know exactly what types of cells to attack. While decimating one cadre of cells, diseases will inexplicably spare a seemingly identical group of neighbors. What makes cells vulnerable or not depends largely on the kinds and amounts of proteins they produce - their 'translational profile,' in the lingo of molecular biology. For this reason, scientists have struggled to parse the subtle molecular differences among the hundreds of specialized cell types that are tangled together in tissues like the brain.
