Calcification is a marked pathological component in carotid artery plaque. Studies have suggested that calcification may induce regions of high stress concentrations therefore increasing the potential for rupture. However, the mechanical behaviour of the plaque under the influence of calcification is not fully understood. A method of accurately characterising the calcification coupled with the ...

Calcification in vitro of the hypertrophic epiphyseal cartilage has served as a useful indicator in the study of the “local factors” involved in calcification (12, 13, 25, 29-31, 34, 37, 38, 40, 44, 54). The appearance of new calcification depends on the functioning of the complete system essential for mineralization. The histological appearance of calcification in vitro of the hypertrophic epi...

OBJECTIVE Arterial hemodynamics and vascular calcification are associated with increased risk for cardiovascular disease, but their inter-relations remain unclear. We sought to examine the associations of arterial stiffness, pressure pulsatility, and wave reflection with arterial calcification in individuals free of prevalent cardiovascular disease. APPROACH AND RESULTS Framingham Heart Study...

The development of vascular calcification is an active, highly regulated process with similarities to bone formation. Osteocalcin (OC), a vitamin K-dependent protein expressed by osteoblasts, contains 3 gamma-carboxyglutamic acid residues derived from the vitamin K-dependent posttranslational modification of glutamic acid residues. Circulating undercarboxylated OC (ucOC) is increased in vitamin...

BACKGROUND Vascular calcification is a common complication associated with chronic kidney disease and the major cause of cardiovascular disease in patients with end-stage renal disease. The vascular calcification risk burden is still unknown in China. This study aims to investigate the prevalence of vascular calcification and assess the predictive value of vascular calcification in patients wit...

PURPOSE To analyze the incidence and patterns of calcification of papillary thyroid microcarcinoma (PTMC) on neck ultrasonography (NUS) and assess the clinical implications of calcification, especially for neck node metastasis. METHODS The clinical data of 379 patients with PTMC who underwent thyroidectomy between January and December 2011 were retrospectively analyzed. PTMC lesions were clas...

Dystrophic calcification in the skin occurs in association with a variety of disorders. To determine the association between subcutaneous calcification and chronic venous insufficiency, X-ray examinations were performed in 20 patients with chronic venous insufficiency and in 20 control subjects to detect latent calcification in their lower legs. Of the 20 patients, 13 (65%) had subcutaneous cal...

OBJECTIVE Calcification in atherosclerotic plaques is a novel marker of atherosclerosis and is related to cardiovascular disease. However, its relationship with cerebrovascular disease has not been investigated extensively. We investigated the relationship between calcification in various vessel beds outside the brain and imaging markers of vascular brain disease. METHODS AND RESULTS A total ...

OBJECTIVES The present study was designed to examine the associations of coronary calcification assessed by electron beam computed tomography (CT) with measures of extracoronary atherosclerosis. BACKGROUND Although measures of extracoronary atherosclerosis have been used to predict coronary events, it is not yet known to what extent those measures reflect coronary atherosclerosis. METHODS The R...

BACKGROUND Carotid artery atherosclerosis is an important risk factor for stroke. As such, quantitative imaging of carotid artery calcification, as a proxy of atherosclerosis, has become a cornerstone of current stroke research. Yet, population-based data comparing the computed tomography (CT) and cardiovascular magnetic resonance (CMR) for the detection and quantification of calcification rema...
