High-molecular-weight von Willebrand factor (vWf) multimers were separated from their smaller multimers by molecular-sieve chromatography and were measured by several sandwich enzyme-linked immunosorbent assays (ELISA) with monoclonal antibodies (moABs) against human vWf. The epitopes of these moABs
In order to investigate the mechanisms of increased plasma inactive renin in diabetics with microvascular complications, changes in active and inactive renin with the progress of diabetes mellitus were studied, and effects of standing on inactive renin release and the relationship between plasma
Advanced glycation end products (AGEs) and receptor RAGE interaction contribute to endothelial cell damage in diabetes. Several thrombogenic abnormalities are also involved in diabetic vascular complications. However, the pathological role of thrombin and protease-activated receptor-1 (PAR-1) system
There is increasing evidence that the complement system plays an important role in diabetes and the development of diabetic vascular complications. In particular, mannan-binding lectin (MBL) levels are elevated in diabetes patients, and diabetes patients with diabetic nephropathy have higher MBL
Cardiovascular complications are the leading cause of morbidity and mortality in diabetic patients. Endothelial dysfunction with impaired endothelial nitric oxide (NO) synthase (eNOS) activity is a widely accepted cause of diabetic vasculopathy. The mechanisms of endothelial dysfunction in diabetes
Diabetic micro- and macroangiopathies are leading causes of acquired blindness, end-stage renal failure and accelerated atherosclerosis, which could account for disabilities and high mortality rates in patients with diabetes. Recent large landmark clinical studies have shown that intensive control
Diabetic angiopathy may be due, in part, to increased growth in vascular cells. We have investigated serum growth factors in Type 2 (non-insulin-dependent) diabetic and healthy subjects and their effect on cultured human arterial smooth muscle cells and fibroblasts. Removal of the dialyzable serum
Thickening of the capillary basement membrane is the fundamental morphological alteration of diabetic microangiopathy. Leucocyte neutral proteases can degrade basement membrane in vivo. The activity of a purified neutral protease from granulocytes is inhibited by alpha2-macroglobulin. It is
Thrombomodulin (TM) is a constituent glycoprotein of endothelial cell membrane, and soluble TM is present also in plasma and urine. It was revealed by experiments using cultured HUVEC in vitro that TM is released from endothelial cell membrane not with monensin, thrombin, fibroblast growth factor,
Diabetes is associated with significant morbidity and mortality in the setting of acute coronary syndromes. Exists a progressive relationship between glucose levels and cardiovascular risk. Hyperglycemy in fact produces endothelial dysfunction recognised to be a key accessory to diabetic
A reasonable interpretation of the present evidence indicates that diabetes, when a complication of periodontitis, acts as a modifying and aggravating factor in the severity of periodontal infection. Diabetics with periodontitis who were young and poorly controlled, those who were long-duration
Mounting evidence indicates that adverse activation of the complement system plays a role in the development of diabetic vascular complications. Plasma levels of the complement proteins mannan-binding lectin (MBL) and its associated serine proteases (MASP-1 and MASP-2) are elevated in diabetes. We
Endothelial tight junctions (TJs) in the retina are potential therapeutic targets for diabetic complications such as retinopathy. TJs primarily determine the endothelial barrier, regulating vascular permeability to maintain tightly closed circulating homeostasis. Our recent study has demonstrated
