Sick worms help elucidate viral infections.

It's no secret that vascular health declines with age. Contributing to this decline is dysfunction of the endothelium, the inner lining of the blood vessels. Normally, a functional endothelium enables coagulation, platelet adhesion and immune activity. However, its dysfunction is associated with reduced anticoagulant properties and an inability of arteries and arterioles to dilate fully, which contribute to the development of various diseases, especially cardiovascular disease. Endothelial dysfunction also reduces exercise capacity with age.
