Blood tests are necessary, easy-to-perform and low-cost alternatives for monitoring of oncolytic virotherapy and other biological therapies in translational research. Here we assessed three candidate proteins with the potential to be used as biomarkers in biological fluids: two glucuronidases from E. coli (GusA) and Staphylococcus sp. RLH1 (GusPlus), and(More)
Oncolytic virotherapy is safe and clinically active in solid tumors, however its efficacy in hematologic malignancies as well as in combination with checkpoint inhibitors and radiation is unexplored. To simulate advanced lymphoma, A20 cells were injected subcutaneously on bilateral flanks of BALB/c mice and treatment initiated on day 17 to only the right(More)
The abnormal colonization of gastrointestinal tract (GIT), the loss of the intestinal barrier function, the bacterial translocation (BT) are signs of intestinal insufficiency which are supposed to be involved in the pathogenesis of MODS. This worsens the condition or leads to lethal outcome in patients after major abdominal surgery in ICU. The goal of this(More)
BACKGROUND Recent reports emphasize the important role of oxidative stress in the genesis of many syndromes and diseases. The ICU patients have prerequisites for activation of oxidative stress process: activation of the neutrophils, macrophages, and other cells which are capable of producing reactive oxygen species (ROS). The traditional opinion was that(More)
BACKGROUND Abdominal compartment syndrome (ACS) manifests with increase of intra abdominal pressure (IAP) and organ dysfunction resulting in multiple organ failure. ACS presents with respiratory failure, hemodynamic changes, and impaired renal function. ACS is most often observed in critically ill patients with peritonitis, gastric dilatation, intestinal(More)
Recently the endoscopic surgery enters widely in clinical practice. Laparoscopic surgery has gained rapid acceptance in the anaethesiological community, mainly due to its advantages to patients in postoperative period. Recognition of pathophysiological changes in hemodynamic, respiration associated with pneumoperitoneum helps to prevention of possibly fatal(More)
Oncolytic vaccinia virus (VACV) therapy is an alternative cancer treatment modality that mediates targeted tumor destruction through a tumor-selective replication and an induction of anti-tumor immunity. We developed a humanized tumor mouse model with subcutaneous human tumors to analyze the interactions of VACV with the developing tumors and human immune(More)
The authors reveal the formation of free radicals in biologic objects stressing upon the influence of Propofol (Diprivan; Zeneca; London, UK) as an intravenous agent during laparoscopic cholecystectomy (LCCE) lipid peroxidation. Some LCCE surgical details help this process resulting in free radical synthesis. The antioxidant effect of Propofol in vitro(More)
