Objectives: Radioactive marking can be a valuable extension to minimally invasive surgery. The technique has been clinically applied in procedures involving sentinel lymph nodes, parathyroidectomy as well as interventions in thoracic surgery. Improvements in equipment and techniques allow one to improve the limits.

Background: Aortic occlusion causes ischemia/reperfusion injury, kidney and spinal cord being the most vulnerable organs. Erythropoietin improved ischemia/reperfusion injury in rodents, which, however, better tolerate ischemia/reperfusion than larger species. Therefore, we investigated whether erythropoietin attenuates porcine aortic occlusion ischemia/reperfusion injury.

Objective: It is well-established that poly(ADP)ribose-polymerase (PARP) assumes major importance during ischemic brain damage, and the selective PARP-1 inhibitor PJ34 reduced spinal cord damage in murine aortic occlusion-induced ischemia/reperfusion injury. We investigated the effect of the PARP-1 inhibitor INO1001 on aortic-occlusion-related porcine spinal cord injury.

Design And Setting: Prospective, randomized, controlled experimental study in an animal laboratory.

Objective: We previously reported in healthy volunteers that a cantaloupe melon extract chemically combined with wheat gliadin (melon extract/gliadin) and containing SOD, catalase and residual glutathione peroxidase (GPx), protected against DNA strand-break damage induced by hyperbaric oxygen (HBO), a well-established model of DNA damage resulting from oxidative stress. Aortic cross-clamping is a typical example of ischemia/reperfusion injury-related oxidative stress, and therefore we investigated whether this melon extract/gliadin would also reduce DNA damage after aortic cross-clamping and reperfusion.

Design: Prospective, randomized, controlled experimental study.

Inhibition of poly (ADP-ribose) polymerase 1 (PARP-1) improved hemodynamics and organ function in various shock models induced by sepsis or ischemia/reperfusion. PARP-1, however, is also referred to play a pivotal role for the maintenance of genomic integrity. Therefore, we investigated the effect of the PARP-1 blocker INO-1001 on hemodynamics, kidney function, and DNA damage and repair during porcine thoracic aortic cross-clamping.

Objective: To investigate the hemodynamic and metabolic effects of the peroxisome proliferator-activated receptor (PPAR)-gamma ligand and nuclear-factor (NF)-kappa B inhibitor 15-deoxy-Delta12,14-prostaglandin-J2 (15d-PGJ2) during long-term, hyperdynamic porcine endotoxemia.

Design: Prospective, randomized, controlled experimental study with repeated measures.
