Complete response with oblimersen combination improves survival of CLL patients

Relapsed chronic lymphocytic leukemia (CLL) patients who had a complete response to combination therapy that included the drug oblimersen survived significantly longer than patients treated with chemotherapy alone, a team led by researchers at The University of Texas M. D. Anderson Cancer Center reports at the 49th Annual Meeting of the American Society of Hematology.

Discovery of potential "getting drunk" gene

A variant of a gene involved in communication among brain cells has a direct influence on alcohol consumption in mice, according to a new study by scientists supported by the National Institute on Alcohol Abuse and Alcoholism (NIAAA), part of the National Institutes of Health (NIH), and the U.S. Army.

Missing brain protein may be one of the culprits behind autism and other brain disorders

The protein helps synapses develop. Synapses--through which neurons communicate with one other-underlie our ability to learn and remember. Now Li-Huei Tsai, Picower Professor of Neuroscience at MIT, has uncovered an enzyme that is key to that protein's activity.

Implanting embryonic cardiac cells prevents arrhythmias

When researchers at Cornell, the University of Bonn and the University of Pittsburgh transplanted living embryonic heart cells into cardiac tissue of mice that had suffered heart attacks, the mice became resistant to cardiac arrhythmias, thereby avoiding one of the most dangerous and fatal consequences of heart attacks.

Positive results from trial of investigational anti-epilepsy drug Brivaracetam

UCB has announced data demonstrating that anti-epileptic drug (AED) brivaracetam, with the proposed trade name Rikelta, administered as an adjunctive treatment in adults with refractory epilepsy with partial onset seizures, significantly reduced seizure frequency and had a side-effect profile comparable to placebo.

Re-engineered Gleevec reduces heart risks

Using a new bottom-up approach for rational drug design, researchers at Rice University and the University of Texas M. D. Anderson Cancer Center have reengineered the powerful anticancer drug imatinib - best known by its brand name Gleevec - to more specifically target one type of cancer while potentially curbing a rare life-threatening cardiotoxic side effect.

sLRP1-alpha provides relief from neuropathic pain

Injury to peripheral nerves (the causes of which include shingles, HIV-AIDS, toxins, alcoholism, repetitive motion disorders, surgery, and cancer) causes neuropathic pain, which differs from ordinary pain and is usually perceived as a steady burning, pins and needles, electric shock sensations, and/or tickling.
