The present studies show for the first time that demineralized bone re-calcifies rapidly when incubated at 37 °C in rat serum: re-calcification can be demonstrated by Alizarin Red and von Kossa stains, by depletion of serum calcium, and by uptake of calcium and phosphate by bone matrix. Re-calcification is specific for the type I collagen matrix structures that were calcified in the original bo...

introdouction:the styloid process(sp) has the potential for calcification and ossification. the aim of this study was to investigate the prevalence of different patterns of elongation and calcification of the sp. materials and methods: in this cross-sectional study, 400 digital panoramic radiographs taken for routine dental examination in the dental school of shiraz university were evaluated fo...

conclusion statistical analysis of susceptibilities of ms patients versus healthy subjects found no excess deposition of calcium content in deep gray matter of ms patients. calcification may not be considered as a biomarker of prognosis in ms. results magnetic susceptibility(x) of calcium content was assessed by number of pixels induced by gp and put in ms patients as well as healthy subjects. ...

a case of multiple pulp stones, a supernumerary tooth and a congenitally missed tooth accompanied by several developmental dental anomalies concurrently affect- ing the upper and lower anterior teeth in an iranian healthy girl is reported. devel- opmental tooth abnormalities are usually found in conjunction with certain diseases or conditions. in the present case, although the patient had consa...

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...
