PURPOSE Calcification is an important prognostic factor in aortic valve stenosis. However, there is no ultrasound (US) method available to accurately quantify calcification in this setting to date. We aimed to validate a new US method for measuring the amount of calcium in an in vitro model, and compare it to computed tomography (CT), the current imaging gold standard. MATERIALS AND METHODS A...

purpose : to report clinical and pathological features of three cases of opacification with hydrophilic acrylic intraocular lenses (iols) case reports : in this interventional case report, we introduce the surgical and laboratory information about three hydrophilic acrylic iols which calcified after implantation for these patients with cataract. these lenses were explanted and analyzed with opt...

Vascular calcification, long thought to result from passive degeneration, involves a complex, regulated process of biomineralization resembling osteogenesis. Evidence indicates that proteins controlling bone mineralization are also involved in the regulation of vascular calcification. Artery wall cells grown in culture are induced to become osteogenic by inflammatory and atherogenic stimuli. Fu...

The control of serum phosphorus (P) and calcium-phosphate (Ca x P) product is critical to the prevention of ectopic calcification in chronic renal failure (CRF). Whereas calcium (Ca) salts, the most commonly used phosphate binders, markedly increase serum Ca and positive Ca balance, the new calcium- and aluminum-free phosphate binder, sevelamer hydrochloride (RenaGel), reduces serum P without a...

conclusions the relationship between calcification of tooth and maturation of cervical bones was significant. this suggested that tooth calcification stages from panoramic radiographs might be clinically useful as a maturity indicator. results all correlation values obtained were statistically significant (p < 0.001). correlations between dental development and skeletal maturity stage due to cv...

Coralline algae are important components in a large variety of ecosystems. Among them, rhodoliths group free-living coralline red that cover extensive coastal areas, from tropical to polar regions. In contrast other ecosystem engineers, limited research efforts preclude our understanding their physiology, underlying mechanisms, drivers and potential differences related species under varying env...

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...

objective: the aim of this study is to measure the effect of different condensation pressure on the microleakage of mineral trioxide aggregate (mta).  methods: this study was an invitro study. a total of 55 single rooted straight-canal human extracted sound teeth free of cracks or calcification were selected. teeth were sectioned from cej region at 3 mm above the root apex. remaining specimens ...
