Diabetes mellitus, dyslipidemia, hypertension, inflammation and hyperhomocyteinemia are major cardiovascular risk factors. Aim: to evaluate the effects of Icodextrin and amino acid peritoneal dialysis fluid (AAPDF) on these major cardiovascular risk factors looking for a more biocompatible PDF formula. Methods: 24 adult stable peritoneal dialysis patients were included in the study. 12 patients received 2L Icodextrin and other 12 patients received 2L AAPDF in their dialysis prescription for 8 weeks. Results: Icodextrin decreased fasting plasma glucose (p Conclusions: A biocompatible PDF should provide not only adequate dialysis and ultrafiltration but should also improve nutritional and metabolic status, blood pressure control and reduce inflammation and plasma homocyteine.展开更多

This approach faces no numerical difficulties as the thickness becomes very small. The solution of a fully clamped rectangular plate is presented using two different series solutions. The results of a square plate are compared with the results of the classical plate theory, Reissner- Mindlin theory and the three dimensional theory of elasticity for different aspect ratios. Two types of clamped boundary conditions are investigated. The obtained results show that Bergan-Wang approach gives good agreement for both very thin and moderately thick plates.展开更多
