Heterotrophy is known to stimulate calcification of scleractinian corals, possibly through enhanced organic matrix synthesis and photosynthesis, and increased supply of metabolic DIC. In contrast to the positive long-term effects of heterotrophy, inhibition of calcification has been observed during feeding, which may be explained by a temporal oxygen limitation in coral tissue. To test this hyp...

OBJECTIVES We sought to determine clinical and laboratory correlates of calcification of the coronary arteries (CAs), aorta and mitral and aortic valves in adult subjects with end-stage renal disease (ESRD) receiving hemodialysis. BACKGROUND Vascular calcification is known to be a risk factor for ischemic heart disease in non-uremic individuals. Patients with ESRD experience accelerated vascu...

BACKGROUND Cardiovascular disease is common in older adults with end-stage renal disease who are undergoing regular dialysis, but little is known about the prevalence and extent of cardiovascular disease in children and young adults with end-stage renal disease. METHODS We used electron-beam computed tomography (CT) to screen for coronary-artery calcification in 39 young patients with end-sta...

Background: Although the radial artery (RA) is mostly selected for the creating of arterio-venous fistula (AVF) in end-stage renal disease patients (ESRDP), it still represents a suitable site to simply assess systemic calcification. Our goal of this study was to research the RA before the arteriovenous fistula creation in ESRDP and evaluate the risk factor determinants. Material and Methods: T...

Experiments were carried out to investigate rat aortic allograft calcification using valved abdominal aortic allografts. Results indicated that this was a potentially useful model for investigating fresh allograft calcification, as well as mineralization of glutaraldehyde-crosslinked valved allografts. Valve cusp results, however, were not comparable to those noted in large animal or human stud...

BACKGROUND AND AIM: This study was performed to evaluate and compare the calcification patterns of the stylohyoid ligament in Eagle’s syndrome (ES) patients, and asymptomatic patients with elongated styloid process (SP) via cone-beam computed tomography (CBCT).METHODS: A total of 52 CBCT images in two symptomatic (ES) and asymptomatic groups (n = 26 per group) were assessed. The mean length an...

The present experiments were carried out to test the hypothesis that arterial calcification is linked to bone resorption by determining whether the selective inhibition of bone resorption with osteoprotegerin will inhibit arterial calcification. In the first test, arterial calcification was induced by treating 22-day-old male rats with warfarin, a procedure that inhibits the gamma-carboxylation...

BACKGROUND AND AIM Arterial calcification is often detected on ultrasound examination but its diagnostic accuracy is not well validated. The aim of this study was to determine the accuracy of carotid ultrasound B mode findings in detecting atherosclerotic calcification quantified by cone beam computed tomography (CBCT). METHODS We analyzed 94 carotid arteries, from 88 patients (mean age 70 ± ...

Background: Thymic epithelial tumors (TETs) are the most common located in anterior mediastinum. Calcification is sometimes observed thymomas, especially and has been reported to be an indicator of invasive behavior thymomas. However, whether or not all calcification indicates unclear. The present study therefore analyzed location, size, patterns thymoma relationships between clinicopathologica...

Recessive mutations in the NTE5 gene were recently described in lower-extremity vascular calcification. ENPP1 mutations were previously described in a severe disorder of vascular calcification in infancy. Together these data support that extracellular adenosine and pyrophosphate are essential components of the pathways in vascular disease. Arterial calcification by impairing blood flow and redu...
