Clicks on sponsored links lower than previously reported but show growth potential
08-22-2007 · EurekAlert!Sponsored links are a money maker for search engines, but a Penn State study using a search engine's transaction log indicates consumers click on sponsored listings fewer than two times out of every 10 searches, a rate which suggests consumers still prefer organic or nonsponsored links.

- Jefferson oncologists show less radiation just as effective in fighting brain tumor, saving hearing
11-07-2006 · EurekAlert!
Radiation oncologists have found that giving less radiation than usual is just as effective against a benign but potential devastating brain tumor called an acoustic schwannoma, and better yet, might save more of the patient's hearing. They compared two groups among 115 patients with acoustic schwannomas treated at Thomas Jefferson University Hospital between 1994 and 2005. Both had effective tumor control, but those who received the lower radiation dose had more hearing preserved.

- Panic attacks are linked to poor outcomes for diabetic patients, Group Health study finds
11-20-2006 · EurekAlert!
There is a strong link between panic episodes and increased complications from diabetes, according to a study conducted at Group Health Cooperative, a Seattle-based health system. The work appears in the November issue of General Hospital Psychiatry.Of the 4,385 patients surveyed, 193 reported experiencing recent episodes of panic. Panic episodes were associated with higher blood sugar levels, increased diabetic complications and symptoms, greater disability and lower self-rated health and functioning.

- Study reveals how the brain generates the human tendency for optimism
10-24-2007 · EurekAlert!
A neural network that may generate the human tendency to be optimistic has been identified by researchers at New York University. As humans, we expect to live longer and be more successful than average, and we underestimate our likelihood of getting a divorce or having cancer. The results, reported in the most recent issue of Nature, link the optimism bias to the same brain regions that show irregularities in depression.

- New inhibitor has potential as cancer drug
10-22-2007 · EurekAlert!
Laboratory experiments have previously shown that cancer cells overproduce an enzyme, heparanase, which splits the body's own polysaccharide heparan sulfate into shorter fragments. The amount of enzyme is related to the degree of malignancy. Today a study is being published in the journal Nature Chemical Biology in which Uppsala University researchers show, on the basis of animal models, that an inhibitor for heparanase would be extremely interesting as a drug candidate.

- Waste not, want not: Role for caveolin-3 in muscular dystrophy
10-12-2006 · EurekAlert!
Muscular dystrophies are characterized by skeletal muscle weakness due to muscle fiber wasting and loss. Kawasaki Medical School researchers now show in the JCI that mice lacking caveolin-3 -- a protein that helps form a scaffold onto which other signaling molecules assemble at the cell plasma membrane -- increases the intracellular activity of myostatin, an inhibitor of muscle growth, and leads to muscle wasting. Myostatin inhibition may have potential as a therapy for certain muscular dystrophies.

- Jefferson scientists identify protein key to breast cancer spread, potential new drug target
04-09-2007 · EurekAlert!
Researchers at the Kimmel Cancer Center at Jefferson have identified a protein that they say is key to helping a quarter of all breast cancers spread. The finding, reported online the week of April 9, 2007, in the journal Proceedings of the National Academy of Sciences, could be a potential target for new drugs aimed at stopping or slowing the growth and progression of breast cancer.

- Researchers call for investigation into links between khat use and psychiatric disorders
06-04-2007 · EurekAlert!
Researchers investigating the evidence for a potential causal link between khat use and mental illness have called for improved research on the stimulant plant, and its possible association with psychiatric disorders. The researchers suggest that only by improving the quality of future research, and integrating social, medical and pharmacological studies, can a more incisive understanding of the psychological and social impact of khat on individuals and communities be gained.

- Scientists take next step in understanding potential target for Ovarian cancer treatment
07-16-2007 · EurekAlert!
A traffic cop protein in the cell may have an even more important role: transporting a messenger protein that tells components in the nucleus to stop cell growth. Scientists are studying the normal function of a protein called 'km23', the traffic cop protein, because the team previously found altered forms of the protein in 42 percent of tumor tissue samples taken from women with Ovarian cancer. The discovery of this additional role may lead to diagnostic tools and earlier treatments for Ovarian cancer.
