This paper deals with the emergence of perceived age discrimination climate on the company level and its performance consequences. In this new approach to the field of diversity research, we investigated (a) the effect of organizational-level age diversity on collective perceptions of age discrimination climate that (b) in turn should influence the(More)
INTRODUCTION Non-invasive assessment of steatosis and fibrosis is of growing relevance in non-alcoholic fatty liver disease (NAFLD). 1H-Magnetic resonance spectroscopy (1H-MRS) and the ultrasound-based controlled attenuation parameter (CAP) correlate with biopsy proven steatosis, but have not been correlated with each other so far. We therefore performed a(More)
UNLABELLED In patients with chronic hepatitis C virus (HCV) infection, several variants of the interleukin-28B (IL28B) gene have been shown to correlate significantly with a sustained virologic response (SVR). Recent evidence shows that determination of one single IL28B polymorphism, rs12979860, is sufficient for predicting treatment outcome. We examined(More)
BACKGROUND Resection as the only potential cure for colorectal liver metastasis is limited by the size and the intrahepatic localization of lesions. Radiofrequency ablation (RFA) may extend the limitations of surgery. PATIENTS AND METHODS 23 consecutive patients suffering from a total of 128 colorectal liver metastases were treated by resection and(More)
Our objective was to investigate the levels of chemokines (MIP1-alpha, MCP-1, and Gro-alpha), Interleukin-18 (IL-18), and Interleukin (IL-6) in bronchoalveolar lavage (BAL) fluid and serum at the onset and ongoing states of sepsis as defined by the American College of Chest Physicians/Society of Critical Care Medicine in septic surgical ICU patients. Our(More)
This paper seeks to advance the diversity literature by investigating organizational performance consequences of age diversity. Drawing from social-identity and socialcategorization theory, we theoretically argue that, in age-diverse companies, age-based subgrouping processes occur, favouring a shared perception of a negative age-discrimination climate.(More)
Low levels of insulin-like growth factor I (IGF-I) in critical illness are observed despite increased or normal levels of growth hormone (GH). The mechanisms for this apparent GH resistance have not been elucidated. As many of the acute inflammatory responses in critical illness are mediated by the proinflammatory cytokines interleukin 1 beta (IL-1 beta)(More)
BACKGROUND The epidemiology and morbidity of Epstein-Barr virus (EBV) infection in pediatric renal transplant recipients have been characterized insufficiently. METHODS In a prospective, multicenter study among 106 pediatric kidney allograft recipients aged 11.4 ± 5.9 years, we investigated the epidemiology of EBV infection and the relationship between(More)
The effect of acetyl - tyrosyl-valyl-alanyl-aspartyl - chloromethylketone (ac-YVAD-cmk), an irreversible caspase-1 (IL-1beta converting enzyme, ICE) inhibitor on mortality, leukocyte and platelet counts and cytokine levels was investigated in a double-blind rat model of endotoxaemia. Intravenous (i.v.) bolus administration of lipopolysaccharide (LPS) (25-75(More)
Epstein-Barr virus (EBV) primary infection constitutes a serious risk for pediatric transplant recipients, particularly as regards the development of EBV-related post-transplant lymphoproliferative disease (PTLD). Currently, there is no established prophylactic regimen. We investigated the association between chemoprophylaxis with valganciclovir (VGCV) or(More)
