Magnetic resonance imaging is a radiation-free alternative to x-ray with excellent soft tissue contrast in arbitrary slice orientation. Here, we assessed real-time MRI-guided coronary interventions from femoral access using newly designed MRI technologies.

One donor-associated risk factor with negative affect of transplantation outcome is brain death (BD). Many rat models for BD and KTx have been developed in the last decade, but no surgical guidelines have been developed for these models.

Background: The noble gas helium induces cardio- and neuroprotection by pre- and post-conditioning. We investigated the effects of helium pre- and post-conditioning on the brain and heart in a rat resuscitation model.
Methods: After approval by the Animal Care Committee, 96 Wistar rats underwent cardiac arrest for 6 min induced by ventricular fibrillation.
Background: Brain death (BD) is a donor-associated risk factor that negatively affects transplantation outcome. The inflammation associated with BD appears to have a negative effect on organ quality. Complement activation, apoptosis, and pro-inflammatory cytokine and chemokine expression are significantly increased after BD.

We evaluated a tape removal test with regard to detection of sensorimotor deficit, comparing it to the Neurological Deficit Score (NDS) in an established model of global cerebral ischaemia after CA in rats.
Methods: Rats were subjected to either 6 min of CA followed by cardiopulmonary resuscitation (CPR) or a sham operation.
Background: Global cerebral ischemia is associated with delayed neuronal death. Given the role of caspases in apoptosis, caspase inhibitors may provide neuronal protection after cardiac arrest. To this end, the authors generated a transgenic rat line expressing baculovirus p35, a broad-spectrum caspase inhibitor, in central neurons.

Therefore, a protective action of BDNF against the delayed degeneration of vulnerable neurons has been suggested. We have investigated the neuroprotective action of BDNF in global ischemia induced by a four-vessel occlusion in the rat.

We first report on the development of a model of reversible cardiocirculatory arrest in mice and the consequences of such an insult to neuronal degeneration and expression of immediate early genes (IEG) in the hippocampus. Cardiocirculatory arrest of 5 min duration was induced via ventricular fibrillation in mechanically ventilated NMRI mice.
