Hepatocellular carcinoma (HCC) is one of the most frequent visceral neoplasms worldwide. Using RT-PCR, ELISA, microdissection and immunohistochemistry, we investigated the expression profiles of CCL19, CCL20, CCL21 and CXCL12 and their receptors in tumourous and tumour neighbouring tissues from patients with HCC and in nonmalignant liver lesions,(More)
BACKGROUND The application of iloprost, a stable prostacyclin analogue, by inhalation has been shown to improve hemodynamic variables in patients with primary pulmonary hypertension. However, repetitive inhalations are required due to its short-term effects. One potential approach to prolong and increase the vasorelaxant effects of aerosolized iloprost(More)
Psychological data from 560 male survivors of acute myocardial infarction (AMI) were documented in the third week after onset of AMI. The psychodiagnostic assessment was designed to detect different forms of depression as well as hyperactive behaviour. A complete follow-up of these patients, which covers a period of 6 months, is available. Our findings(More)
OBJECT The goal of this study was to determine whether in meningiomas cytogenetic findings are suitable as a predictive parameter relevant to prognosis. METHODS Between 1992 and 1998 at the Department of Neurosurgery, Saarland University, 198 patients underwent surgery to resect meningiomas. The meningiomas were investigated cytogenetically and the(More)
BACKGROUND The pulmonary circulation is an important site for the production and clearance of endothelin (ET)-1, a potent vasoactive and mitogenic peptide. In healthy individuals, 40% to 50% of circulating ET-1 is removed on each passage through the lungs resulting in an arteriovenous ratio of <1, whereas many patients with pulmonary arterial hypertension(More)
Glioblastoma multiforme (GBM), a malignant astrocytic tumour, represents the most frequent tumour of the human brain. Nevertheless, its molecular pathology is not well understood. We utilized the immune system, which contributes to cancer protection, to help identify new GBM-related genes. By screening a human GBM cDNA library with autologous patient serum(More)
PURPOSE Transanal endoscopic microsurgery (TEM) is a technique that has found its place in routine practice due to its minimal invasive character and associated low morbidity. The purpose of this study was to assess the influence of anatomical variables of rectal neoplasms as well as surgeon experience on postoperative complications in patients undergoing(More)
OBJECTIVE Complete arterial coronary artery bypass grafting with 2 grafts can be achieved even in triple vessel disease by use of a T configuration. There is still uncertainty whether the coronary flow reserve in the main stem of the left internal thoracic artery is sufficient to supply more than 1 anastomosed coronary vessel. METHODS Between March 1996(More)
BACKGROUND Hematopoietic stem-cell transplantation is a well-established treatment in various hematologic malignancies, but the outcome depends on disease relapse, infections, and the development and severity of acute and chronic graft-versus-host disease. Some evidence has revealed an important role for the nonclassical major histocompatibility complex(More)
The aim of our study was to observe the effects on gait parameters induced by STN stimulation and levodopa medication in patients with advanced Parkinson's disease in order to determine different or additive effects. Therefore we examined 12 patients with advanced Parkinson disease after bilateral implantation of DBS into the STN. We assessed the motor(More)
