Study provides insight into effective treatments for autism spectrum disorder, seizures

Roughly 25-35% of individuals with autism eventually develop seizures and many of the remainder have subclinical seizure-like brain activity. However, little is known about which traditional epilepsy treatments and commonly used non-traditional alternative treatments are effective for treating seizures or epilepsy in children and adults with autism spectrum disorder.

Hyperion HPN-100 phase III pivotal study for urea cycle disorders meets primary endpoint

Hyperion Therapeutics, Inc. today announced that the Company's phase III pivotal study of glycerol phenylbutyrate (HPN-100), an investigational drug for the treatment of urea cycle disorders (UCDs), met its primary endpoint. The non-inferiority study, conducted under a Special Protocol Assessment (SPA) granted by the U.S. Food and Drug Administration (FDA) in June 2009, evaluated the ammonia control of glycerol phenylbutyrate as compared to sodium phenylbutyrate (BUPHENYL®).

Matchmaker function may help cardiologists understand the natural repair process after heart attacks

Heart muscle cells do not normally replicate in adult tissue, but multiply with abandoned during development. This is why the loss of heart muscle after a heart attack is so dire-you can't grow enough new heart muscle to make up for the loss.

Study examines effects of AEDs on nicotine metabolite levels in smokers

UMDNJ-Robert Wood Johnson Medical School researchers have determined that carbamazepine and oxycarbamazepine, medications commonly used to treat neurologic and psychiatric conditions, increase nicotine metabolism in smokers. As nicotine metabolism increases, cravings for nicotine return more quickly which could lead to more frequent cigarette consumption among individuals who also take these medications.

Valproic acid halts vision loss in patients with retinitis pigmentosa

Researchers at the University of Massachusetts Medical School believe they may have found a new treatment for retinitis pigmentosa, a severe neurodegenerative disease of the retina that ultimately results in blindness. One of the more common retinal degenerative diseases, RP is caused by the death of photoreceptor cells and affects 1 in 4,000 people in the United States. RP typically manifests in young adulthood as night blindness or a loss of peripheral vision and in many cases progresses to legal blindness by age 40.

Embryonic stem cells raise hope of cellular replacement therapy for liver failure

Embryonic stem (ES) cells, known for their capacity to proliferate indefinitely and differentiate into almost all types of cells including hepatocytes, have raised the hope of cellular replacement therapy for liver failure. There have been several protocols available for hepatic fate specification from ES cells, however, most of the protocols currently used result in low yield or purity of functional hepatocytes. Valproic acid (VPA), a histone deacetylase inhibitor, has been demonstrated to facilitate the hepatic differentiation of mesenchymal stem cells. However, little is know about whether VPA could induce the hepatic differentiation of ES cells.

Hyperion Therapeutics enrolls first patient in HPN-100 phase III clinical trial for urea cycle disorders

Hyperion Therapeutics today announced that the first patient has been enrolled in its pivotal phase III clinical trial of investigational compound HPN-100 (glycerol phenylbutyrate). The 4-week, multi-center, randomized, double-blind, cross-over study is designed to evaluate the non-inferiority of glycerol phenylbutyrate to BUPHENYL® (sodium phenylbutyrate) Tablets and Powder in adults with urea cycle disorders.

Blocking folic acid action during early pregnancy leads to increased risk of abnormalities in growing baby

Using medication that reduces or blocks the actions of folic acid during the first trimester of pregnancy (weeks 1-12), increases the risk that the growing baby will develop abnormalities. This conclusion was reached by a team of Epidemiologists, Paediatricians, Clinical Pharmacologists, Obstetricians and Gynaecologists who examined birth and abortion data collected in Israel between 1998 and 2007.

Medications to reduce folic acid during pregnancy increase the risk of abnormalities in fetus

Pregnant women are advised to take vitamin supplements containing folic acid as part of their routine pre-natal care. Now, a new study warns that taking medications that reduce or block the actions of folic acid during the first trimester of pregnancy increase the risk that the growing baby will develop abnormalities.

People with manic depression have a distinct chemical signature in their brains

People with manic depression have a distinct chemical signature in their brains, according to a new study.

Enzyme important in fetal heart-cell failure - findings provide new targets for treatment

In almost all forms of heart failure, the heart begins to express genes that are normally only expressed in the fetal heart. Researchers have known for years that this fetal-gene reactivation happens, yet not what regulates it.
