Viagra and Levitra ED drugs shown to allow more chemo to reach brain tumors

In a study using laboratory animals, researchers found that medications commonly prescribed for erectile dysfunction opened a mechanism called the blood-brain tumor barrier and increased delivery of cancer-fighting drugs to malignant brain tumors.

Hydrogen sulfide significantly improves survival after extreme blood loss

For the first time, researchers have demonstrated that the administration of minute amounts of inhaled or intravenous hydrogen sulfide, or H2S - the molecule that gives rotten eggs their sulfurous stench - significantly improves survival from extreme blood loss in rats.

CSL Behring study shows extended half-life recombinant VIIa leads to longer biologic activity

CSL Behring today presented results of a pre-clinical study that not only demonstrates the feasibility of genetically fusing factor VIIa to human albumin, but that this therapeutic protein with a prolonged half-life can lead to a longer biologic effect.

Cancer drug shows promise as treatment for pulmonary hypertension

A drug developed to fight cancer is showing early promise as a treatment for pulmonary hypertension, researchers from the University of Chicago Medical Center report May 19 at the American Thoracic Society International Conference in Toronto, Canada.

Regenerative medicine offers hope in spinal cord injury

Spinal cord injury (SCI) can be a catastrophic event for the individual. Traditionally, such injuries were viewed as permanent, irreversible neurological dysfunction, but over time research has shown some neuroplastic capability of the injured adult mammalian spinal cord. However, spontaneous functional recovery post-SCI is very modest.

Potential drug target identified for diabetes by studying novel gut-brain-liver circuit

Scientists at the Toronto General Hospital Research Institute have discovered a novel signaling pathway between three organs - the gut, the brain, and the liver - which lowers blood sugar when activated.

Treatment with an anti-psychotic drug found to cause changes in metabolism earlier than expected

Schizophrenia is a complex type of psychotic mental illness characterized by thoughts that are uncoupled from reality.

Beta-blockers heal the heart via the brain when administered during heart failure

Up to now, it was thought that beta-blockers work directly on the heart, but the new study shows that the drugs may also act via the brain, suggesting that future therapies to treat cardiovascular disease could be targeting the central nervous system.

Diltiazem reduces cocaine cravings in a rat model

Researchers from Boston University School of Medicine and Harvard Medical School have found that diltiazem, a drug used in the treatment of high blood pressure, reduces cocaine cravings in a rat model.

Researchers engineer first system of human nerve-cell tissue

Researchers at the University of Pennsylvania School of Medicine have demonstrated that living human nerve cells can be engineered into a network that could one day be used for transplants to repair damaged to the nervous system.

Gene therapy - immune system discovery may lead to effective treatment for glioblastoma multiforme

A new gene therapy approach that attracts and "trains" immune system cells to destroy deadly brain cancer cells also provides long-term immunity, produces no significant adverse effects and -- in the process of destroying the tumor -- promotes the return of normal brain function and behavioral skills, according to a study conducted by researchers at Cedars-Sinai Medical Center's Board of Governors Gene Therapeutics Research Institute.

Nausea from chemotherapy explained

A new study from the Monell Center increases understanding of the biological mechanisms responsible for the nausea and vomiting that often afflict patients undergoing chemotherapy.

Telmisartan potent against stroke

Telmisartan, a drug widely used to help control blood pressure, may have uniquely potent activity in preventing stroke, according to a new study conducted in an animal model.

Stem cell therapy rescues motor neurons in ALS model

In a study that demonstrates the promise of cell-based therapies for diseases that have proved intractable to modern medicine, a team of scientists from the University of Wisconsin-Madison has shown it is possible to rescue the dying neurons characteristic of amyotrophic lateral sclerosis (ALS), a fatal neuromuscular disorder also known as Lou Gehrig's disease.
