Improved In vivo imaging of atherosclerotic plaque development ... read more
September 28, 2018
Researchers have developed a method for quantitatively assessing atherosclerotic plaque buildup in mice. They transplanted X-ray-irradiated low-density-lipoprotein-knockout mice with bone marrow cells expressing near-infrared fluorescent protein, which subsequently developed into fluorescent macrophages. These macrophages congregated specifically in atherosclerotic plaques that arose after feeding on a high-cholesterol diet. In vivo imaging detected the amount of aortic plaque formed and its change over time, which could help in assessing the efficacy of anti-atherosclerotic drugs.

September 25, 2018
When assessing whether preschoolers are overweight, health professionals should use other measures such as waist-to-height ratio in addition to the body mass index (BMI). A study shows that this is because measuring the BMI of younger children often fails to identify those with excess stomach fat and possible associated health problems.
