Runx2 and Vascular Calcification
Complications arising from vascular calcification, the inappropriate deposition of calcium phosphate crystals in the vasculature, have become more evident in recent years as human longevity has increased. Arterial calcification is frequently categorized as two types, depending on where it occurs: …

Bioprosthetic heart valves : ultrastructure and calcification
… of these valves proved most resistant to all anticalcification treatments, aortic wall tissue stood in the centre of our analyses. 2) Subsequently, three main determinants of the fixation process namely: delay, temperature and fixative-concentration were varied with the goal of significantly …

THE ROLE OF ENDOTHELIAL CELLS IN VASCULAR CALCIFICATION
… cardiovascular risk, mostly due to vascular calcification (VC). By now, it’s quite clear how, in vitro and in vivo, vascular smooth muscle cells (VSMCs) actively participate to VC. In contrast to the wide studies on VSMCs, the role of endothelial cells (ECs) has been poorly investigated. It’s …

Coronary Artery Calcification and Its Progression in Cancer Patients
Research over the last several decades has demonstrated that cancer and its corresponding therapies are associated with an increased risk of ischemic heart disease in cancer survivors as compared to the general population. Though several mechanisms have been proposed, the reasons for this …

Establishing the Physical Basis for Calcification by Amorphous Pathways
The scientific community is undergoing a paradigm shift with the realization that the formation of carbonate minerals with diverse compositions and textures can be understood within the framework of multiple pathways to mineralization. A variety of common minerals can form via an amorphous pathway, …

Arterial Calcification and the Clinical Implications on Stent Function
… in a specific arterial setting. Arterial calcification, observed clinically with mild to severe levels, was investigated to determine the impact on stent performance. The analysis demonstrated that arterial calcification does significantly affect stent function, resulting in a 60% increase …

The Relation of Temperature to Calcification in MONTIPORA VERRUCOSA
<p>A method for quantitatively comparing calcification rates in coral was used to find an optimum growth temperature for <em>Montipora verrueosa.</em> This method is based on the uptake of the radioactive isotope ca<sup>45</sup>. By supplying the water the corals are growing i·n with a known amount …

Molecular Regulation of Vascular Calcification In Murine Models of Atherosclerosis
<p><strong>Background</strong>: Calcification occurs often in the atherosclerotic lesions of patients with coronary heart disease and animals with hypercholesterolemia, such as apolipoprotein-E deficient (ApoE-/-) mice. However, the mechanism(s) underlying the development of calcification in …

Coronary Artery Calcification and Waist-Height Ratio in Adult Men
비만은 고혈압, 당뇨병, 고지혈증과 연관이 있으며 심혈관계 질환을 증가시킨다. 이러한 비만을 보는 지표 중 허리둘레/키 비가 다른 지표에 비해 실용적이고 유용하다는 연구들이 있었다. 또한 관상동맥 석회화는 심혈관 질환의 위험인자로 대사증후군과 비만이 연관이 있다는 것은 알려져 있으며, 관상동맥 석회화 수치는 이러한 관상동맥 석회화를 정량적으로 본 수치이다. 이에 관상동맥 석회화 수치와 허리둘레/키 비와의 연관성을 알아보고자 하였다. 이 연구는 2004년 7월부터 2009년 12월까지 수원시 소재 일개 대학병원 검진센터에서 …

The role of lipoproteins in vascular calcification and plaque stabilisation
Vascular calcification (VC) is a feature of atherosclerotic plaques and is associated with co-morbidities such as diabetes and chronic kidney disease. While its presence is used by cardiologists to identify higher risk patients, increasing data suggests that the morphology of calcification is also …

Uraemic vascular damage and calcification in children with chronic kidney disease
… functional vascular abnormalities and arterial calcification begins early in the course of renal decline and can be found even in children, contributing to their high mortality risk. Through clinical and laboratory studies, this thesis sought to investigate the causes of uraemic vascular damage …

Coral calcification : insights from inorganic experiments and coral responses to environmental variables
Coral calcification is examined using a laboratory model and living corals. In the laboratory model, abiogenic aragonite formed at high saturation state (Ω>~20) had a granular appearance and was enriched in trace elements, similar to centers of calcification and dark bands in corals. Abiogenic …

Developing an Inducible Osteoclast System as a Cell Therapy for Ectopic Calcification
Ectopic calcification (EC) is a complex disease in which mineral develops in abnormal locations. It can develop in a variety of locations throughout the body, including the vasculature, heart valves, and in orthopedic settings where it is more commonly referred to as heterotopic ossification (HO). …

Molecular imaging of calcification and inflammation in aortic valve disease and atherosclerosis
… PET/CT correlated with tissue markers of active calcification and predicted the genesis of new areas of calcification within the aortic valve. 18F-fluoride uptake was associated with disease progression and clinical events. In the coronary cohort, 80 volunteers were recruited. In patients with …

Mechanisms of Coral Calcification: a Geochemical and Computational Approach to Understanding Biomineralisation
… grow. The more robust our understanding of coral calcification, the better we will be able to constrain our estimates of past environmental change and predict how coral calcification will be impacted in the future. This thesis uses geochemical and computational approaches to understand the …

Coral calcification : insights from inorganic experiments and coral responses to environmental variables
… are examined using a laboratory model for coral calcification and the growth of living corals under different environmental conditions. Abiogenic aragonite was precipitated from seawater over a range of saturation states (Chapter 1). Abiogenic aragonite formed at high saturation state …
