A Minimal Model Explains Aging Regimes and Guides Intervention Strategies Open
Aging varies widely across species yet converges on uni-versal laws such as Gompertzian mortality. We propose a minimal framework that reduces this complexity to three macroscopic variables: the leading stress response ( z 0 ), cumulative …

High volume retrograde portography for better discrimination of the portal vein during TIPS procedure Open
Background: Imaging of the portal vein prior to puncture for TIPS is essential. Purpose: With this study, we examined a modified retrograde portography with regard to the reliable representation of the portal vein. Material and Methods: Pr…
