Recent advances in biologically based ecosystem models of the coupled terrestrial, hydrological, carbon, and nutrient cycles have provided new perspectives on the terrestrial biosphere's behavior globally, over a range of time scales. We used the terrestrial ecosystem model Century to examine relationships between carbon, nitrogen, and water dynamics. The model, run to a quasi-steady-state, shows strong correlations between carbon, water, and nitrogen fluxes that lead to equilibration of water/energy and nitrogen limitation of net primary productivity.

Plasminogen activator inhibitor-1 (PAI-1) is involved in the accumulation of extracellular matrix in various tissues. Since peritoneal interstitium is one of the resistance sites for transport during peritoneal dialysis (PD), the peritoneal PAI-1 level may have a significant effect on peritoneal transport. It was the purpose of this study to examine the associations between plasma or dialysate PAI-1 levels and the variables of peritoneal transport during peritoneal equilibration tests (PET) in 25 stable, adult PD patients.

Plasminogen activator inhibitor-1 (PAI-1) is an important regulator of plasminogen activators and has been shown to be involved in the accumulation of extracellular matrix (ECM) in various tissues. Since peritoneal interstitium is one of the main resistance sites of peritoneal transport, the level of PAI-1 in the peritoneum may have a significant effect on water and solute transport during peritoneal dialysis (PD) via its effect of peritoneal ECM. Therefore, we studied the associations between plasma or dialysate PAI-1 levels and the peritoneal transport during standard peritoneal equilibration test (PET) in 8 diabetic and 8 non-diabetic stable PD patients who were matched for their demographical data.

Objective: Plasminogen activator inhibitor-1 (PAI-1) is an important regulator of plasminogen activators and has been shown to be involved in the accumulation of extracellular matrix (ECM) in various tissues. Since peritoneal ECM is a resistance site for peritoneal transport, the production and release of PAI-1 in the peritoneum may affect the peritoneal transport of water and small solutes.
Design: The linear correlations between the dialysate PAI-1 levels and the variables of peritoneal transport during peritoneal equilibration tests (PET) were examined.
