Research suggests new contributor to heart disease

Medical professionals have long known that the buildup of plaque in arteries can cause them to narrow and harden, potentially leading to a whole host of health problems — including heart attack, heart disease and stroke. While high blood pressure and artery stiffness are often associated with plaque buildup, new research from engineers at Washington University in St. Louis shows they are not the direct causes. Their findings suggest a new culprit: elastic fibers in the arterial wall.
Persistent childhood asthma sets stage for COPD

Persistent childhood asthma sets stage for COPD

Children with mild to moderate persistent asthma are at greater risk of developing chronic lung disease as young adults and, therefore, may require lifelong treatment even if their asthma symptoms subside for extended periods, according to a major national study co-led by researchers at the School of Medicine.
Brain imaging links Alzheimer’s decline to tau protein

Brain imaging links Alzheimer’s decline to tau protein

Using a new imaging agent that binds to tau protein and makes it visible in positron emission tomography (PET) scans, scientists at Washington University School of Medicine in St. Louis have shown that measures of tau are better markers of the cognitive decline characteristic of Alzheimer’s than measures of amyloid beta seen in PET scans.
Making everyday decisions

Making everyday decisions

Researchers at Washington University School of Medicine in St. Louis have found that some neurons in the orbitofrontal cortex assign value to options in everyday decision-making. The area’s neurons then can re-map to make different decisions when circumstances change.
