Filter by:Rationale: The investigators hypothesize that EPO protects against apoptosis after acute ischemia in man and that it is detectable using the annexin-A5 model. Objective: Does infusion of a single dose of Epoetin Alfa, a short-acting EPO, protect against apoptosis in man after acute ischemia? Study design: A double blinded randomised cross-over study. Study population: 12 Healthy male volunteers, between 18 and 40 years old. Intervention: All 12 volunteers will receive a single dose of EPO and placebo in a randomized order. A six week wash-out period is obtained in order to avoid interference of both treatments. Main study parameters/endpoints: The percentage of difference between radioactivity (quantified as counts per pixel) of the experimental and control thenar muscle at one and four hours after reperfusion.
The evaluation of the efficacy of an intraportal infusion with Tacrolimus, at the time of liver graft implantation, compared to a control group without immunosuppressive intraportal infusion (Placebo: Saline solution 0.9%) with respect to the initial liver function measured by the parameters of the liver function (LFP): AST (U/L), ALT (U/L), total Bilirubin (mg/dL) and the coagulation factors: NT (%), PTT (s), INR.
Ischemic injury to muscular tissue is common in cardiovascular medicine. The most effective treatment to avoid ischemic damage is the rapid re-establishment of reperfusion. However, reperfusion itself can result in additional damage to ischemic tissue. This phenomenon is called ischemia - reperfusion (IR) injury and is caused by different pathologic mechanisms. Therapies are required which can be administered after the onset of an ischemic event to protect the tissue against IR injury. Therefore, a promising strategy to reduce IR injury is post-conditioning. Likewise, pharmacological therapies administered after the onset of reperfusion might prevent tissue injury. We have recently shown that high concentrations of exogenous vitamin C abrogate experimental IR injury of the forearm vasculature in patients with peripheral artery disease and in healthy subjects. Study hypothesis We hypothesize that the administration of mechanical post-conditioning or of high-dose vitamin C may protect skeletal muscle against IR injury. This shall be studied employing MR spectroscopy of the leg, which is an established model to assess muscle aerobic energy metabolism. Design Three periods, three way cross over study in 10 volunteers. One screening visit, three one-day study days with two washout periods of >3 days in between are scheduled for each participant. The order of experimental days will be randomized. After the last treatment a final follow-up examination will be performed within one week.
Sevoflurane preconditioning and cardiovascular protection against ischemia/reperfusion injury. Study hypothesis: The volatile anesthetic sevoflurane at subanesthetic concentrations achieves endothelial protection against ischemia/reperfusion injury and reduces inflammatory markers in the circulation
Does caffeine reduce rosuvastatin induced protection against ischemia reperfusion injury?
This study is performed to determine whether a seven day treatment with dipyridamole (slow release, 200mg twice daily) can induce a protective effect against ischemia-reperfusion injury, after ischemic exercise of the non-dominant forearm in healthy volunteers.
To adjust our forearm model for ischemia reperfusion injury, in order to used it for assessment of ischemia reperfusion damage in elderly and patients. To test the effect of ischemic postconditioning on ischemia reperfusion injury in healthy volunteers, using Annexin binding after repetitive handgripping.
To study the impact of 3 day exposure to atorvastatin 80mg on Annexin A5 targeting after ischemic exercise in the non-dominant forearm.
The purpose of this project is to explore the interaction between caffeine and dipyridamole on ischemia-reperfusion injury in the forearm.
Cardiovascular disease is the leading cause of death in diabetic patients due to both a high event rate and a worse outcome. A pharmacological intervention that reduces ischemia-reperfusion-injury would improve the outcome of diabetic patients after a cardiovascular event. In the present study, we will use annexinA5 scintigraphy to address the following hypothesis: Rosiglitazone reduces ischemia-reperfusion-injury in humans with insulin resistance.
