Discovery of key contributor to Alzheimer's disease process

Walter J. Lukiw, PhD, Associate Professor of Neuroscience and Ophthalmology at LSU Health Sciences Center New Orleans, is the lead author of a paper identifying, for the first time, a specific function of a fragment of ribonucleic acid (RNA), once thought to be no more than a byproduct, in regulating inflammation and the development of Alzheimer's disease.

Breakthrough in cell-type analysis offers new ways to study development and disease

Like skilled assassins, many diseases seem to know exactly what types of cells to attack. While decimating one cadre of cells, diseases will inexplicably spare a seemingly identical group of neighbors. What makes cells vulnerable or not depends largely on the kinds and amounts of proteins they produce - their 'translational profile,' in the lingo of molecular biology. For this reason, scientists have struggled to parse the subtle molecular differences among the hundreds of specialized cell types that are tangled together in tissues like the brain.

Researchers uncover beneficial mechanism of the helpful "Dr. Jekyll" side of the Cdk5 protein

Researchers at UT Southwestern Medical Center have uncovered new insights into the "Dr. Jekyll and Mr. Hyde" nature of a protein that stimulates stem-cell maturation in the brain but, paradoxically, can also lead to nerve-cell damage.

High-fat diet during pregnancy makes new cells in fetal brain that cause early onset obesity

A study in rats shows that exposure to a high-fat diet during pregnancy produces permanent changes in the offspring's brain that lead to overeating and obesity early in life, according to new research by Rockefeller University scientists.

General anesthesia for hernia surgery in children and risk of later developmental problems

Children under the age of three who had hernia surgery showed almost twice the risk of behavioral or developmental problems later compared to children who had not undergone the surgery, according to a study by researchers at Columbia University Mailman School of Public Health and the College of Physicians and Surgeons.

10 years of stem cells science

Ten years ago this month (Nov. 6, 1998), the publication in the journal Science of a short paper entitled "Embryonic Stem Cell Lines Derived from Human Blastocysts" rocked biology - and the world - as the all-purpose stem cell and its possibilities were ushered into the limelight.
