Extracorporeal Detoxification Methods in the Treatment of Destructive Pancreatitis
Published 2015-07-01“…The investigation showed the necessity and efficiency the early use of albumin dialysis, hemodiafiltration in the combination treatment of sepsis and septic shock in destructive pancreatitis, leading to a significant reduction in mortality rates. The maximum detoxification potential of albumin dialysis in sepsis complicating the course of destructive pancreatitis is achieved by a combination of different mechanisms for elimination of toxic substances, such as convection, sorption, and diffusion, in the extracorporeal circuit.Conclusion. …”

Speckle-Based Transmission and Dark-Field Imaging for Material Analysis with a Laboratory X-Ray Source
Published 2025-04-01“…The results showed that the CNR of T and DF images increases with larger analysis windows, while linear absorption and diffusion coefficients remain constant. The CNR of T images decreases with increasing ODD due to noise, whereas the CNR of DF images exhibits more complex behaviour, due to the material-dependent reduction in DF signal with increasing ODD. …”
