Reverb (short for reverberation) is the acoustic environment that surrounds a sound. Natural reverb exists everywhere. Whether the space being described is a bathroom or a gymnasium, the essential characteristics remain the same. Reverb is composed of a series of tightly-spaced echoes. The number of echoes and the way that they decay play a major role in shaping the sound that you hear. Many other factors influence the sound of a reverberant space.
Vascular calcification (VC) is a predictor of cardiovascular morbidity and mortality. Hemodialysis (HD) patients suffer from severe vascular calcifications. Matrix Gla protein (MGP) is a central calcification inhibitor of the arterial wall and its activity depends on vitamin K-dependent Î³-glutamate carboxylation. Noncarboxylated MGP, formed as a result of vitamin K deficiency, is associated with cardiovascular disease.
Cartilage matrix is an amorphous gel that contains large amounts of proteoglycans. Distributed throughout this gel are collagen fibrils (Type II) that are too small to be seen with the light microscope. Both the collagen and the proteoglycans are produced by the chondrocytes.
