Abstract Metastatic colorectal cancer is the fourth most common cause of death. Current options in palliation such as hyperthermic intraperitoneal chemotherapy (HIPEC) present severe side effects. Recent research efforts suggested therapeutic use oxidant-enriched liquid using cold physical plasma. To investigate a clinically accepted treatment regimen, we assessed antitumor capacity plasma-treated saline solution. In response to liquid, CT26 murine colon cells were readily oxidized and...

Gas plasma technology generates reactive oxygen and nitrogen species (ROS/RNS), inducing lethal oxidative damage in tumor cells. The transfer of gas plasma–derived ROS/RNS into liquids has been proposed as an innovative anti-cancer strategy targeting peritoneal carcinomatosis (PC). However, the mechanism action is under debate. To this end, we compared plasma–oxidized medical-grade sodium chloride (oxNaCl) with a concentration-matched control (cmc) NaCl enriched equivalent concentrations H 2...

In a search for functions of transforming growth factor-beta during early embryonic development we used two different experimental approaches. the first made use stem (ES) cells. ES cells in culture differentiate to derivatives all three germ layers and mimic some aspects organogenesis when grown as aggregates suspension form embryoid bodies. Differentiation proceeds further bodies attach suitable substrates. Muscle neuronal are among most readily identified cell types then formed. We...
