Calcification can be deposited throughout the vasculature in several forms of calcium phosphate, including calcium hydroxyapatite (CHA). Calcium accumulation in arteries by mineralization and calcium loss from bone by osteoporosis often coexist, and vascular calcification may share common mechanisms with bone remodeling. Deposition of calcification in valves and arteries diminishes the valvular...

BACKGROUND Calcification of the thoracic aorta is associated with atherosclerotic risk factors, yet its pathogenesis and clinical implications are not yet elucidated. The goal of the present study was to assess whether thoracic aorta calcification is associated with an increased risk of cardiovascular events and death in patients with stable angina pectoris. METHODS AND RESULTS A prospective ...

Ectopic calcification is characterized by inappropriate deposition of hydroxyapatite in non-skeletal connective tissues and can cause significant morbidity mortality, particularly when it affects the cardiovascular system. Identification metabolic genetic determinants ectopic could help distinguish individuals at greatest risk developing these pathological calcifications guide development medic...

The role of orbital computed tomography (CT) in the management of retinoblastoma is reviewed. All 21 patients with retinoblastoma studied with high-resolution computed tomography had intraocular calcification demonstrable in at least one eye. 83% of tumours showed evidence of calcification on CT scan. The degree of calcification appeared to depend on tumour size; only small tumours were devoid ...

AIMS We evaluated the relationship between the mitral inflow velocities by pulsed Doppler echocardiography and mitral annular motion velocities by pulsed Doppler tissue imaging in patients with mitral annular calcification. METHODS AND RESULTS Fifty-three patients with mitral annular calcification were divided into two groups: severe mitral annular calcification (n=15, mitral annular calcific...

Aim: Carotid artery calcification can results in important vascular obstruction. It is reported that the combination of risk factors such as periodontitis, pulp stones contribute to carotid artery calcification. However in the literature, no study has yet investigated carotid artery calcification with respect to tonsillolith. The objective of this study was to investigate whether carotid artery...

chronic total occlusion (cto) intervention is still a challenging problem. the aim of this study is to determine factors that affect pci results.the study was conducted on 72 patients in two centers. cto angioplasty was done by the antegrade approach from the femoral and/or radial approach. the role of age, gender, anatomical variations such as calcification, length of the lesion, proximal bend...

Large benthic foraminifera are significant contributors to sediment formation on coral reefs, yet they are vulnerable to ocean acidification. Here, we assessed the biochemical and morphological impacts of acidification on the calcification of Amphistegina lessonii and Marginopora vertebralis exposed to different pH conditions. We measured growth rates (surface area and buoyant weight) and Ca-AT...

This study examines the properties of calcifying human costal cartilage and adjacent rib bone using qualitative and quantitative micro-computed tomography analysis. Calcifications are categorized with respect to location, microstructure, shape, and contiguity using a novel classification scheme and quantified in terms of mineral density, volume fraction, and length of infiltration from the cost...

Calcification of the vascular tree is common in physiologic and pathologic conditions, i.e., aging, diabetes, dyslipidemia, genetic diseases, and diseases with disturbances of calcium metabolism. In chronic kidney disease, vascular calcification is even more common, develops early, and contributes to the markedly increased cardiovascular risk in this particular population. Pathomorphologically,...
