Resumen
Objective: Although the clinical and biological importance of calcification is well recognized for the extracerebral vasculature, its role in cerebral vascular disease, particularly, intracranial aneurysms (IAs), remains poorly understood. Extracerebrally, 2 distinct mechanisms drive calcification, a nonatherosclerotic, rapid mineralization in the media and a slower, inflammation driven, atherosclerotic mechanism in the intima. This study aims to determine the prevalence, distribution, and type (atherosclerotic, nonatherosclerotic) of calcification in IAs and assess differences in occurrence b

Resumen
Calcification exists in atherosclerotic plaques in the form of nanomineral aggregates and is closely related to the development of atherosclerosis. Spheroidal and massive calcification are two major types of calcification found in atherosclerotic tissue. However, the exact difference between these two types of calcification is still not clear. Samples composed entirely of spheroidal calcifications and massive calcifications were isolated from aortic atherosclerotic plaques and tested using both bulk and microscopic analysis techniques.

<p>Vascular calcification involves the crystallization of calcium/phosphate in the form of hydroxyapatoite in the extracellular matrix of the arterial wall. Vascular calcification is categorized into 3 main etiologies: (1) inflammatory/atherosclerotic (mostly intimal), (2) metabolic (mostly medial), and (3) genetic background (mostly medial). Several overlapping mechanisms trigger all three types of calcifications.

It is generally acknowledged that rupture of an abdominal aortic aneurysm (AAA) occurs when the stress acting on the wall over the cardiac cycle exceeds the strength of the wall. Peak wall stress computations appear to give a more accurate rupture risk assessment than AAA diameter, which is currently used for a diagnose. Despite the numerous studies utilizing patient-specific wall stress modeling of AAAs, none investigated the effect of wall calcifications on wall stress.

Abstract Calcification is a common complication in cardiovascular disease and may affect both arteries and heart valves. Matrix γ-carboxyglutamic acid (Gla) protein (MGP) is a potent inhibitor of vascular calcification, the activity of which is regulated by vitamin K. In animal models, vitamin K antagonists (oral anticoagulants [OACs]) were shown to induce arterial calcification. To investigate whether long-term OAC treatment may induce calcification in humans also, we have measured the grade of aortic valve calcification in patients with and without preoperative OAC treatment.

Mitral valve annular calcification-related valvular disease is increasingly common due to the rising prevalence of age-related mitral annular calcifications. Mitral annular calcification alters the structure and function of the mitral valve annulus, which in turn causes mitral valve regurgitation, stenosis, or both. As it frequently coexists with comorbid conditions and overlapping symptoms, mitral annular calcification-related valvular disease poses significant diagnostic and therapeutic challenges.

Brain computed tomography performed on admission revealed multiple high-intensity lesions in both basal ganglia, both cerebellar hemispheres, and the left frontal lobe. In contrast, brain magnetic resonance imaging (MRI) showed no prominent lesions on T2- and T1-weighted images, and there was no contrast en

Resumen
Neurological signs associated with intracerebral calcifications require a complex management of calcium, phosphate and parathormone levels and search of a series of general and cerebral disease too. The mechanisms of intracerebral calcification in hypoparathyroidism are not completely known. Neurological signs associated with intracerebral calcification are very rarely the presenting symptoms of hypoparathyroidism. We present 2 cases in which the diagnosis of hypoparathyroidism was brought on by several neurological signs and widespread intracerebral calcification.

Resumen
Arterial calcification, which involves calcium deposits in the arterial walls, can be categorized into intimal and medial types. Intimal calcification is often linked to atherosclerotic plaques, while medial calcification is associ-ated with aging and hypercalcemia. This case involves a 52-year-old male with severe chronic kidney disease, who is undergoing dialysis treatment. Panoramic radiography revealed arterial calcifications in common carotid, external carotid, internal carotid, lingual, facial, superior labial, and maxillary arteries, bilaterally.

Resumen
Identifying calcification of arteries in the head and neck region may aid in the diagnosis of advanced systemic conditions. In contrast, failure to recognize them can result in incorrect diagnoses and ineffective treatments. Radiographic analyses can be used to detect such calcifications. This report focuses on calcifications discovered in the facial, lingual, and infraorbital arteries following a routine dental care panoramic radiograph. This report is particularly notable because it is the second in the literature to highlight the calcification of all three arteries.

Resumen
In vascular calcification, as a physiological process, intimal arterial calcification (IAC) associated with increased cardiovascular risk is distinguished from medial arterial calcification (MAC) localized mainly in the lamina elatica interna, which are not only based on different pathophysiological mechanisms. They also lead to different cardiovascular diseases. While intimal arterial calcification involves inflammation and lipid accumulation, a calcification process similar to desmal ossification plays the main role in medial arterial calcification.

Nodular calcification is sometimes detected in the native coronary artery. However, it is very rare to find in a saphenous vein graft (SVG). We herein report a rare case of stable angina pectoris (AP) due to nodular calcification. A 75-year-old man who had previously undergone coronary artery bypass grafting was admitted to our hospital due to stable AP. On angiography, significant stenosis was detected in the proximal SVG. Based on the findings of coronary angiography and optical coherence tomography, a red thrombus was suspected at the culprit lesion. However, nodular calcification was also

We report two cases with long-standing systemic lupus erythematosus (SLE) who developed widespread calcification in subcutaneous tissue and peri-articular structures. To our knowledge only 26 case reports have appeared concerning this abnormality in SLE. However, there has been no report of calcification in an SLE patient in the literature of orthopaedic surgery. The calcifications of the forearm were marginally removed because of pain surrounding them. X-ray analysis revealed that the calcification was made of pure calcium phosphate.

Resumen
Inorganic phosphate (Pi) is a critical determinant of calcification, and its concentration is regulated by alkaline phosphatase (ALP) and Pit1. ALP is a key regulator of osteogenic calcification and acts by modulating local inorganic phosphate (Pi) concentrations through hydrolyzing pyrophosphate in the extracellular matrix (ECM). Pit1, a sodium-dependent phosphate transporter, regulates calcification via facilitating phosphate uptake within the cells. To investigate whether zinc differentially regulates osteoblastic and vascular calcifications, we examined ALP activity and Pit1 in osteoblasti

Abstract Vascular calcification is a marker of increased cardiovascular risk. Vitamin K–dependent matrix Gla protein (MGP) is important in inhibiting calcification. Because MGP activation is vitamin K dependent, we performed a cross-sectional study investigating the relationship between the use of vitamin K antagonists and extracoronary vascular calcification. From the Dutch thrombosis services we selected 19 patients younger than 55 years who had no other cardiovascular risk factors and who had used coumarins for more than 10 years, and compared these to 18 matched healthy controls.

Calcification is a prominent feature of late-stage atherosclerosis, but the mechanisms driving this process are unclear. Using a biobank of carotid endarterectomies, we recently showed that Proteoglycan 4 (PRG4) is a key molecular signature of calcified plaques, expressed in smooth muscle cell (SMC) rich regions. Here, we aimed to unravel the PRG4 role in vascular remodeling and intimal calcification. PRG4 expression in human carotid endarterectomies correlated with calcification assessed by preoperative computed tomographies. PRG4 localized to SMCs in early intimal thickening, while in advanc
