Vascular calcification is associated with cardiovascular disease in hemodialysis (HD) patients. Some reports have previously shown that simple assessment of aortic calcification using plain radiography is associated with cardiovascular (CV) events; however, these studies simply assessed whether aortic calcification was present or absent only, without considering its extent. Here, we ...

Because previous studies have not distinguished between intimal (atherosclerotic) and medial vascular calcification, the prevalence and clinical significance of either condition in chronic or end-stage kidney disease (CKD or ESKD) are unknown. We hypothesized that breast arterial calcification (BAC) is exclusively medial and that mammography can serve as a useful ...

Vascular calcification is very common in end-stage renal disease, especially in hemodialysis patients. Vascular calcification is associated with poor prognosis in hemodialysis patients. The transformation of vascular smooth muscle cells into osteoblast-like cells seems to be a key element in the pathogenesis of vascular calcification. In addition to traditional risk ...

The internal thoracic artery (ITA) and inferior epigastric artery (IEA) may be used as conduits for myocardial revascularization. Harvesting the ITAs and IEAs can lead to clinically significant ischemia of the anterior abdominal wall. We created a registry with data from 108 patients receiving myocardial revascularization with 1 or greater ...

The cramoll 1,4 is a well-studied lectin. However, few studies about its biodistribution have been done before. In this study, we radiolabeled the cramol 1,4 with Tc-99m and analyzed the biodistribution. The results showed that the cramol has an abnormal uptake by the bowel with reflections on its clearance mechanism.
