Magnetic resonance imaging (MRI) measurements of atrophy in an important area of the brain are an accurate predictor of multiple sclerosis (MS), according to a new study published online in the journal Radiology. According to the researchers, these atrophy measurements offer an improvement over current methods for evaluating patients at risk for MS.

The Parkinson's Progression Markers Initiative (PPMI), a landmark biomarker clinical study, has completed enrollment of its initial 600-member cohort of Parkinson's patients and controls, and will launch additional study cohorts to leverage the existing PPMI infrastructure and evaluate multiple potential biomarkers for Parkinson's disease (PD). The first of these new cohorts launches today and will investigate risk factors for PD that may enable diagnosis before the onset of motor symptoms.

Dr. Tom Hudson, President and Scientific Director of the Ontario Institute for Cancer Research (OICR) recently announced a collaboration with Janssen Inc. to find and test new biomarkers to identify patients with hormone resistant prostate cancer at high risk for disease progression and biomarkers of response to therapy. These biomarkers could lead to more personalized treatments and fewer side effects for prostate cancer patients.

Elevated levels of bilirubin in the blood get attention in the clinic because they often indicate that something has gone wrong with the liver. Now researchers have found that male smokers with low levels of the yellow-tinged chemical are at higher risk for lung cancer and dying from the disease.

A team led by researchers at The University of Texas MD Anderson Cancer Center reported its findings in a late-breaking abstract at the AACR Annual Meeting 2013 in Washington, D.C.

Australian scientists are much closer to developing a screening test for the early detection of Alzheimer's disease. They identified blood-based biological markers that are associated with the build up of a toxic protein in the brain which occurs years before symptoms appear and irreversible brain damage has occurred.

In a study using mice, researchers from the University of North Carolina School of Medicine found that a hormone, adrenomedullin, plays a crucial role in preventing the pregnancy complication preeclampsia. Surprisingly, this hormone protects women from preeclampsia when emitted by the fetus, not the mother, during the most critical times in pregnancy.
