Positive new data have been released on a drug candidate, RPC1063, for relapsing multiple sclerosis. According to the results from a six-month Phase 2 study of 258 multiple sclerosis patients, the drug candidate reduced the annualized relapse rate of participants with multiple sclerosis by up to 53 percent, compared with placebo. The potential therapy also decreased the emergence of new brain damage seen by MRI by more than 90 percent.

The link between a protein typically associated with Alzheimer’s disease and its impact on memory and cognition may not be as clear as once thought, according to a new study. Researchers looked at the role of the brain protein amyloid-beta in adults living with Down syndrome, a genetic condition that leaves people more susceptible to developing Alzheimer’s.

A new microscopy technique yields resolution an order of magnitude better than previously possible. Through this new technique, the researchers showed that dystrophin was responsible for regulating tiny molecular fluctuations in calcium channels while muscles are in use. The discovery suggests that a lack of functional dystrophin alters the dynamics of ion channels -- helping to cause the defective mechanical responses and the calcium imbalance that impair normal muscle activity in patients with muscular dystrophy.

Positron emission tomography/computed tomography (PET-CT) is more accurate than conventional CT scanning in measuring response to treatment and predicting survival in patients with follicular lymphoma, and should be used routinely in clinical practice, according to new research.

To diagnose painful kidney stones in hospital emergency rooms, CT scans are no better than less-often-used ultrasound exams, according to a clinical study conducted at 15 medical centers. "Ultrasound is the right place to start," researchers said. "Radiation exposure is avoided, without any increase in any category of adverse events, and with no increase in cost."

A new molecular imaging approach could revolutionize doctors’ ability to see tumors that have metastasized to other sites in the body, including the bones. Preclinical animal models of metastatic prostate cancer helped to pave the way for this new development, which uses bioluminescence, nanoparticles, gene manipulation as components of the exciting new approach to imaging local and metastatic tumors.

In a novel brain-imaging study among trauma victims, researchers have linked an opioid receptor in the brain -- associated with emotions -- to a narrow cluster of trauma symptoms, including sadness, emotional detachment and listlessness. The study holds important implications for targeted, personalized treatment of post-traumatic stress disorder, or PTSD, a psychiatric condition affecting more than 8 million Americans that can cause a wide range of debilitating psychiatric symptoms.

Excess weight causes important alterations in an organism, one of which affects liver function. Fat accumulates in the liver producing hepatic steatosis which can cause inflammation, fibrosis and cirrhosis. To date, the most reliable method for determining hepatic fat has been hepatic biopsy. Imaging techniques such as abdominal ecography detect, but are less precise for determining the quantity of fat. Now a study has shown that magnetic resonance is a good method -- better still than hepatic biopsy -- for detecting fats in the liver and for quantifying them.
