INTRODUCTION Although pilomatrixomas are frequently encountered by dermatologists and pathologists in the differential diagnosis of head and neck lesions, this is not usually the case among head and neck surgeons. A pilomatrixoma (calcifying epithelioma of Malherbe) is a benign tumour of the hair matrix cells. Histologically it is characterised by the presence of ghost cells, basophilic cells a...
OBJECTIVE To evaluate the suitability of citrate-coated very small superparamagnetic iron oxide particles (VSOP) as a contrast agent for identifying inflammation in atherosclerotic lesions using magnetic resonance imaging (MRI). METHODS AND RESULTS VSOP, which have already been evaluated as a blood pool contrast agent for MR angiography in human clinical trials, were investigated in Watanabe ...
BACKGROUND Vascular calcification is an indicator of elevated cardiovascular risk. Vascular smooth muscle cells (VSMCs), the predominant cell type involved in medial vascular calcification, can undergo phenotypic transition to both osteoblastic and chondrocytic cells within a calcifying environment. METHODOLOGY/PRINCIPAL FINDINGS In the present study, using in vitro VSMC calcification studies...
Relationships between six calcifying plankton groups and pH are explored in a highly biologically productive and data-rich area of the central North Sea using time-series datasets. The long-term trends show that abundances of foraminiferans, coccolithophores, and echinoderm larvae have risen over the last few decades while the abundances of bivalves and pteropods have declined. Despite good cov...
PURPOSE The purpose of this study was to describe the clinical and sonographic features of calcifying epitheliomas (pilomatrixomas). METHODS We retrospectively reviewed the clinical data and sonographic appearances of 59 cases of calcifying epitheliomas in 58 patients that were confirmed pathologically. RESULTS The mean age of the patients was 26 years (range, 5-69 years) and the female-to-...
Peripheral Calcifying Odontogenic Cyst (PCOC) is the extraosseous form of calcifying odontogenic cyst that limited to peripheral soft tissue without bony involvement. This case report presents a PCOC manifested as progressive growth gingival mass in young male treated with excisional biopsy. Histological examination confirmed diagnosis presence characteristic ghost cells and sporadic calcificat...
Background & Objective: Calcifying Odontogenic Cyst (COC) (Gorlin) is an uncommon odontogenic lesion. In new classification was named as cystic calcifying odontogenic tumor. Thus, COC which is associated with odontoma is uncommon. There is little information combined lesion, therefore, a case of COC with complex odontomawas reported here. Case Report: The patient was a 39 year old male whic...
Received on: Feb 3, 2012 – Accepted on: Aug 3, 2012 ABSTRACT The calcifying cystic odontogenic tumor normally presents as a painless, slow-growing mass, involving both maxilla and mandible, primarily the anterior segment (incisor/canine area). It generally affects young adults in the third to fourth decades, with no gender predilection. Computerized tomography images revealed important characte...
It has been shown that vesicles play a key role in the onset mechanism of aortic calcification related to cholesterol-induced atherosclerosis. This study using a rabbit model was conducted to determine whether cholesterol exerts a direct effect on vesicle's calcifiability. Inclusion of cholesterol in calcifying media stimulated ATP-initiated deposition of calcium in a dose-dependent manner by v...
Vascular calcification is a complex and dynamic process occurring in various physiological conditions such as aging and exercise or in acquired metabolic disorders like diabetes or chronic renal insufficiency. Arterial calcifications are also observed in several genetic diseases revealing the important role of unbalanced or defective anti- or pro-calcifying factors. Pseudoxanthoma elasticum (PX...
