endocrine tumors of the pancreas (islet-cell tumors) are rare with neuroendocrine origin. the patient was a 41- year- old man, admitted with chief complains of epigastric mass feeling, dull abdominal pain, lack of appetite and weight loss up to 2-3 kg since 6 months ago. in physical examination, a mass was detected in epigaster and left upper quadrant (luq). in abdominal x-ray, a calcified mass...

Abstract Funding Acknowledgements Type of funding sources: Foundation. Main source(s): The Russian Science Foundation Introduction Aortic valve stenosis due to calcification cusps is the most common disease in world today. main feature this condition a progressive mineralization tissue. mechanisms underlying process still unknown, but recent years it has become clear that pathological heart and...

background/objective: hyperphosphatemia is the consequence of end stage renal failure. inadequate control of serum phosphorus results in elevated ca × p product with subsequent soft tissue deposition in the form of conjunctival and corneal calcification.  in this study, we evaluated the relationship of conjunctival and corneal calcification with secondary hyperparathyroidism in hemodialysis pat...

Objective To assess the computed tomography (CT) and magnetic resonance (MR) imaging characteristics of soft tissue rhabdoid tumors (RT) compare them with those rhabdomyosarcoma (RMS). Methods We conducted a retrospective analysis 49 pediatric patients from 2011 to 2022, comprising 16 RT 33 RMS who underwent CT or MRI scans. Key features, as well clinical pathological data, were compared betwee...

In this case an aneurysm of the right posterior communicating artery developed 11 months after an infundibular dilation of this artery had been angiographycally and surgically demonstrated. In the best of the authors' knowledge, there are only eleven such cases reported in the literature. This report brings about diagnostic and therapeutic questions regarding arterial infundibula and the need o...

BACKGROUND Anterior and posterior circulation atherosclerosis differ in vascular risk factors and stroke mechanisms. However, few studies have compared the pathological features between these lesions. Using a series of intracranial artery specimens, we characterized the intracranial atherosclerotic lesions and compared pathological features among different arteries of the intracranial vasculatu...

Objective(s): Vascular calcification is one the major characteristics in patients with various types of chronic inflammatory disorders. MiRNAs have been shown to be involved in many normal biological functions as well as diseases; however, their role in vascular calcification has not received much attention. Materials and Methods: In the current study, we built a vascular calcification rat mode...

Recent reports have suggested that calcium supplements have not been effective in reducing skeletal fractures in older adults. In addition, several other current articles have not been able to demonstrate that calcium supplements or high total calcium intakes are related to coronary artery calcification, although other reports disagree. Yet, other manuscripts have linked high calcium intakes to...

PURPOSE OF REVIEW Among the myriad of players in the calcification of cartilage, ANK is a relatively new entrant. It is a multipass transmembrane protein that regulates the transport of inorganic pyrophosphate between the cell and the extracellular space. Mutations in ANK result in two distinct calcification disorders: craniometaphyseal dysplasia and familial calcium pyrophosphate dihydrate dep...
