Low molecular weight (LMW) heparin has been compared to standard unfractionated (UF) heparin in hemodialysis/hemofiltration in a 12 month, randomized study. Seventy patients with end-stage chronic renal failure starting dialysis treatment were randomly assigned to one of two groups treated with either LMW or UF heparin. The LMW and UF heparin doses used(More)
Lipid peroxidation products, both lipid hydroperoxides and thiobarbituric acid reactive substances (TBARS) were determined in the plasma of 31 uremic patients treated with maintenance hemodialysis. Whereas patients had significantly elevated TBARS compared to 93 healthy controls (4.25 +/- 1.53 vs. 1.66 +/- 0.50 mumol/l; p < 0.01) lipid hydroperoxides were(More)
Fluid withdrawal in over-hydrated patients resistant to diuretics was obtained by means of a capillary haemofilter, using the arterio-venous pressure gradient for blood perfusion at a rate of 100 ml/min. The ultrafiltration rate was 200-600 ml/h and could be maintained as long as 48 h without changing the haemofilter. This method, which needs no technical(More)
Nearly ten years after its first presentation and five years after its first application to operating systems, the suitability of <i>Aspect-Oriented Programming (AOP)</i> for the development of operating system kernels is still highly in dispute. While the AOP advocacy emphasizes the benefits of AOP towards better configurability and maintainability of(More)
—Traditional operating systems differentiate between threads, which are managed by the kernel scheduler, and interrupt handlers, which are scheduled by the hardware. This approach is not only asymmetrical in its nature, but also introduces problems relevant to real-time systems because low-priority interrupt handlers can interrupt high-priority threads. We(More)
— System software strongly relies on the availability of static as well as dynamic adaptation techniques. With Aspect-Oriented Programming (AOP) it is now possible to adapt even policy-like crosscutting concerns in the implementation of system software. While this is straightforward in the static case, dynamic adaptation of crosscutting concerns requires an(More)
It may be concluded from our results to date, that arteriovenous hemofiltration is an accurate and reliable method for the management of fluid balance in patients resistant to diuretics. Early use of this method may improve the prognosis of intensive-care patients by decongestion or dehydration of lungs, reduction of cardiac pre-and after-load and(More)
