BACKGROUND Atherosclerosis is a major complication of diabetes, but the mechanisms by which diabetes promotes macrovascular disease have not been fully delineated. Although several animal studies have demonstrated that inhibition of ACE results in a decrease in the development of atherosclerotic lesions, information about the potential benefits of these(More)
Impulsivity was contrasted between 32 subjects with a history of drug-dependence (DRUG+) and 26 subjects with no drug use history (DRUG-) using both behavioral and self-report measures. The hypothesis was that the DRUG+ group would be more impulsive than the DRUG- group. Subjects in the DRUG+ group self-reported more of a tendency toward impulsivity than(More)
The interrelationships of sodium and volume status, atrial natriuretic peptide (ANP), plasma renin activity (PRA), insulinlike growth factor I (IGF-I), and kidney weight and their influence on glomerular filtration rate (GFR) were investigated in rats during the first 4 wk of streptozocin-induced diabetes (STZ-D). In each of three experiments, untreated(More)
Streptozotocin-induced pancreatic injury is commonly used for creating rodent models of type 1 diabetes which develop renal injury with similarities to human diabetic nephropathy. This model can be established in genetically modified rodents for investigating the role of molecular mechanisms and genetic susceptibility in the development of diabetic(More)
To evaluate the role of nitric oxide (NO) in diabetic hyperfiltration, renal hemodynamic changes and changes in urinary excretion of NO2/NO3 in response to the NO inhibitor nitro-L-arginine methyl ester (L-NAME) and the NO-donating agent glyceryl trinitrate (GTN) were investigated in conscious streptozocin-induced diabetic (D) and age-matched control (C)(More)
Advanced glycation end product (AGE) formation may contribute to the progression of atherosclerosis, particularly in diabetes. The present study explored atherosclerosis in streptozotocin-induced diabetic apolipoprotein E-deficient (apoE-/-) mice that were randomized (n = 20) to receive for 20 weeks no treatment, the AGE cross-link breaker ALT-711, or the(More)
In the diabetic kidney, clinical as well as experimental observations have shown an upregulation of growth factors such as PDGF. These studies, however, were not designed to address whether upregulation of PDGF is merely a manifestation of diabetic renal injury or whether PDGF plays an active role in the pathophysiology of diabetic nephropathy. The(More)
There is convincing evidence that the endothelin system contributes to diabetic nephropathy and cardiovascular disease. This study aimed to assess the effects of the non-peptidergic endothelin receptor A (ETA) antagonist avosentan in a mouse model of accelerated diabetic nephropathy and atherosclerosis in comparison with the ACE inhibitor, quinapril.(More)
OBJECTIVE Diabetes is associated with accelerated atherosclerosis, the major factor contributing to increased mortality and morbidity in the diabetic population. The molecular mechanisms by which diabetes promotes atherosclerosis are not fully understood. Platelet-derived growth factor has been shown to play a major role in the pathology of vascular(More)
BACKGROUND It remains controversial whether specific blockade of the renin-angiotensin system confers superior antiatherosclerotic effects over other antihypertensive agents in diabetes. Therefore, the aim of this study was to compare equihypotensive doses of the angiotensin II subtype 1 (AT1) receptor blocker irbesartan with the calcium antagonist(More)
