Central fat mass versus peripheral fat and lean mass: Opposite (adverse versus favorable) associations with arterial stiffness? The Amsterdam growth and health longitudinal study

Ferreira, I. (author), Snijder, M.B. (author), Twisk, J.W.R. (author), van Mechelen, W. (author), Kemper, H.C.G. (author), Seidell, J.C. (author), Stehouwer, C.D.A. (author), TNO Arbeid (author)

Central and peripheral fatness seem to confer opposite (i.e. adverse vs. protective) effects on cardiovascular risk, but how this occurs is not clear. In addition, the role of peripheral lean mass needs to be elucidated. We therefore investigated, in 336 (175 women) 36-yr-old and apparently healthy adults, the relationship between trunk fat,...

Heterogeneous nature of microalbuminuria in NIDDM: Studies of endothelial function and renal structure

Fioretto, P. (author), Stehouwer, C.D.A. (author), Mauer, M. (author), Chiesura-Corona, M. (author), Brocco, E. (author), Carraro, A. (author), Bortoloso, E. (author), van Hinsbergh, V.W.M. (author), Crepaldi, G. (author), Nosadini, R. (author), Gaubius Instituut TNO (author)

Microalbuminuria (MA) is associated with microangiopathy (renal and retinal lesions) in insulin-dependent diabetic (IDDM) patients. In contrast MA does not reflect microvascular damage in a substantial number of non- insulin-dependent diabetic (NIDDM) patients. MA predicts cardiovascular disease in NIDDM patients with increased von Willebrand...

Dysfunction of the vascular endothelium is considered an early step in the development of diabetic angiopathy. Hyperglycaemia results in endothelial dysfunction, both through direct effects of glucose and through formation of advanced glycosylation end-products (AGEs). We hypothesized that the effects of glucose and AGEs on endothelial function...
