For fats, longer may not be better
Researchers have uncovered why some dietary fats, specifically long-chain fats, such as oleic acid (found in olive oil), are more prone to induce inflammation. Long-chain fats, it turns out, promote increased intestinal absorption of pro-inflammatory bacterial molecules called lipopolysaccharides (LPS). This study appears in the January issue of JLR.
Growth of new brain cells requires 'epigenetic' switch
New cells are born every day in the brain's hippocampus, but what controls this birth has remained a mystery. Reporting in the January 1 issue of Science, neuroscientists at the Johns Hopkins University School of Medicine have discovered that the birth of new cells, which depends on brain activity, also depends on a protein that is involved in changing epigenetic marks in the cell's genetic material. more
‘Stroke belt’ deaths tied to non-traditional risk factors
Southerners die from stroke more than in any other U.S. region, but exactly why that happens is unknown. A new report by researchers at the University of Alabama at Birmingham (UAB) and the University of Vermont underscores that geographic and racial differences are not the sole reasons behind the South's higher stroke death rate. more
Obesity starts in the head? Six newly discovered genes for obesity have a neural effect
Obesity is known to increase the risk of chronic disorders, such as diabetes (type 2). An international team of scientists with German participation through the Helmholtz Zentrum München identified six new obesity genes. Gene expression analyses have shown that all six genes are active in brain cells. more
Study shows California's autism increase not due to better counting, diagnosis
A study by researchers at the UC Davis M.I.N.D. Institute has found that the seven- to eight-fold increase in the number children born in California with autism since 1990 cannot be explained by either changes in how the condition is diagnosed or counted — and the trend shows no sign of abating.
McGill researchers discover gene that increases susceptibility to Crohn's disease
Researchers at McGill University, the Research Institute of the McGill University Health Centre (RI MUHC) and the McGill University and Génome Québec Innovation Centre, along with colleagues at other Canadian and Belgian institutions, have discovered DNA variations in a gene that increases susceptibility to developing Crohn's disease. Their study was published in the January issue of the journal Nature Genetics. more
OHSU School of Dentistry team discovers new molecule in blood-pressure control system
Researchers at Oregon Health & Science University's School of Dentistry have discovered that the nerve cells controlling heart rate and blood pressure synthesize a molecule known to be critically important for proper nervous system growth. The finding could someday play a significant role in the prevention of Sudden Infant Death Syndrome (SIDS) and high blood pressure. more
