Hepatocellular carcinoma (HCC) is the second leading cause of death by cancer worldwide. Resection and liver transplantation are the gold standards, but only a minority of people are eligible. Percutaneous ablation therapies, such as microwave ablation (MWA), have consequently been developed. There is a lack of guidelines regarding the treatment of HCCs in end-stage renal disease (ESRD) patients. Here, we report the case of a 67-year-old patient who was undergoing peritoneal dialysis (PD) for chronic congestive heart failure and who presented with an HCC while undergoing PD...

Microwave ablation (MWA) has been proposed to suffer less from the heat sink effect compared to radiofrequency ablation but has been reported to cause extension of the ablation zone along intrahepatic vessels in clinical practice. To study this effect in detail, eight fresh porcine livers were perfused in an ex-vivo organ perfusion system. Livers were perfused with oxygenated, O-positive human blood at 37°C. Perfusion was discontinued immediately before ablation in the non-perfused group (n = 4) whilst in the perfused group (n = 4) perfusion was maintained during MWA (140W X 2min)...

Amorphous oxide semiconductor-based thin film transistors (TFTs) have been considered as excellent switching elements for driving active-matrix organic light-emitting diodes (AMOLED) owing to their high mobility and process compatibility. However, oxide semiconductors have inherent defects, causing fast transient charge trapping and device instability. For the next-generation displays such as flexible, wearable, or transparent displays, an active semiconductor layer with ultrahigh mobility and high reliability at low deposition temperature is required...
