OBJECTIVE Both pregnancy and diabetes are thought to predispose to the impairment of oral health. As saliva contributes to oral homeostasis, we have characterised its properties and flow rate in pregnant women with or without diabetes. DESIGN Unstimulated whole mixed saliva was collected from 63 women in the first trimester of pregnancy and analysed for(More)
Vascular endothelial growth factor (VEGF) and transforming growth factor-β1 (TGF-β1) are key mediators of adverse peritoneal membrane remodeling in peritoneal dialysis eventually leading to ultrafiltration failure. Both are pleiotropic growth factors with cell type-dependent regulation of expression and biological effects. Here we studied regulation of(More)
Serum has been considered an unsuitable medium for measurements of circulating vascular endothelial growth factor (VEGF) since platelets release significant quantities of VEGF during clotting. Nevertheless, the assessment of platelet-derived VEGF may be important in patients with acute coronary syndromes characterized by intraluminal thrombosis. The present(More)
Percutaneous coronary intervention (PCI) became standard treatment modality for coronary revascularization. However, it is associated with endothelial cell denudation, which may predispose to in-stent thrombosis and restenosis. Since statins may inhibit vascular cell proliferation, one may fear that their early administration will delay post-PCI(More)
Peritonitis is characterized by a coordinated influx of various leukocyte subpopulations. The pattern of leukocyte recruitment is controlled by chemokines secreted primarily by peritoneal mesothelial cells and macrophages. We have previously demonstrated that some chemokines may be also produced by human peritoneal fibroblasts (HPFB). Aim of our study was(More)
Peritoneal inflammation and fibrosis are responses to the uremic milieu and exposure to hyperosmolar dialysis fluids in patients on peritoneal dialysis. Cells respond to high osmolarity via the transcription factor nuclear factor of activated T cells (NFAT5). In the present study, the response of human peritoneal fibroblasts to glucose was analyzed in(More)
Uraemia and long-term peritoneal dialysis (PD) can lead to fibrotic thickening of the peritoneal membrane, which may limit its dialytic function. Peritoneal fibrosis is associated with the appearance of myofibroblasts and expansion of extracellular matrix. The extent of contribution of resident peritoneal fibroblasts to these changes is a matter of debate.(More)
Percutaneous coronary intervention is increasingly performed in elderly patients. Because the procedure is associated with endothelial cell (EC) denudation, we compared recovery of young and old ECs from scratch injuries inflicted in culture. Although senescent ECs displayed markedly reduced potential to proliferate and migrate, they repopulated the wounds(More)
1. Accumulation and distribution of lead in tissues of Eisenia foetida (Oligochaeta) living in soils with different concentrations PbO2 was studied histochemically and with the use of the dithizione method. 2. The earthworms absorb lead from the soil through the alimentary canal as well as through the body wall. this leads to considerable accumulation of(More)
Fibrotic thickening of the peritoneum develops in patients receiving peritoneal dialysis (PD) for renal failure. For unknown reasons, however, in some patients it progresses to extensive fibrosis that compromises dialysis capacity of the peritoneum. It is increasingly clear that fibroblasts display large heterogeneity not only between but also within(More)
