The Effects of Discontinuation of Vitamin K Antagonists on the Rate of Elastin Degradation

Background: Elastin is a unique protein providing elasticity, resilience and deformability to dynamic tissues, such as lungs and vasculature. Elastin fibers are characterized by their high affinity for calcium. However, calcified elastin is more prone to the degrading effects of proteases and, in turn, partially degraded elastin has an even ...

Effects of Vitamin D Supplementation During a Non-surgical Treatment of Generalized Chronic Periodontitis

It is likely that a chronically low intake of vitamin D and calcium may lead to a negative calcium balance, thus causing a secondary increase in calcium removal from bone, including the alveolar bone. Such bone loss may contribute to weakening of the tooth-attachment apparatus. In addition to its action ...
