Publikováno v: Hormone and Metabolic Research. 43:223-225

The male reproductive tract has been identified as a target tissue for vitamin D, and previous data suggest an association of 25-hydroxyvitamin D [25(OH)D] with testosterone levels in men. We therefore aimed to evaluate whether vitamin D supplementat

Diffusion-weighted magnetic resonance imaging for the detection of ischemic brain lesions in coronary artery bypass graft surgery: relation to extracorporeal circulation and heparinization

Autor: N, Mirow, A, Zittermann, H, Körperich, J, Börgermann, H, Koertke, H, Knobl, J, Gieseke, B, Ostertun, T, Coskun, K, Kleesiek, W, Burchert, J F, Gummert

Publikováno v: The Journal of cardiovascular surgery. 52(1)

Cognitive decline is a well recognized complication after on-pump coronary artery bypass graft (CABG) surgery. We investigated whether the design of extracorporeal circulation (ECC) and the extent of perioperative heparinization have an impact on neu

Heparin-coated extracorporeal circulation in combination with low dose systemic heparinization reduces early postoperative blood loss in cardiac surgery

Autor: N, Mirow, A, Zittermann, H, Koertke, A, Maleszka, H, Knobl, T, Coskun, K, Kleesiek, R, Koerfer

Publikováno v: The Journal of cardiovascular surgery. 49(2)

According to a recently performed meta-analysis, heparin-bonded circuits do not reduce blood loss in cardiac surgery patients compared to nonheparin-bonded circuits within the first 24 h postoperatively. We investigated the effects of heparin-coated

Publikováno v: The Journal of cardiovascular surgery. 41(6)

The aim of this study was to observe the changes in left-ventricular morphology, the improvement in hemodynamics and the survival curves (according to Kaplan-Meier) of patients following transaortic myectomy.From November 1985 to August 1997, transao
