For the extension of high level languages by data types of mode relation, three language constructs are proposed and discussed: a repetition statement controlled by relations, predicates as a generalization of Boolean expressions, and a constructor for relations using predicates. The language constructs are developed step by step starting with a set of(More)
Scoping, naming and binding are central concepts in the deenition and understanding of programming languages. With the introduction of sophisticated data models, these issues become important for query languages as well. Additionally, the goal of integrating query and programming languages requires a common basis for their operational semantics. We ooer(More)
PURPOSE Perioperative regional anesthesia with consecutive reduction of intra- and postoperative systemic opioid requirements in order to improve oncological result after cancer surgery has only been addressed by a few reports. This hypothesis has never been proved in esophageal cancer with a long-term follow-up of more than 5 years. Therefore, we addressed(More)
Objectives: The relation of procalcitonin (PCT) plasma concentrations compared with C-reactive protein (CRP) was analyzed in patients with different severity of multiple organ dysfunction syndrome (MODS) and systemic inflammation. II score and survival were evaluated in 40 patients with systemic inflammation and consecutive MODS over a period of 15 days.(More)
For successful systemic stem cell therapy, mesenchymal stem cells (MSCs) must transmigrate across the endothelium and invade their target tissue. To date, most of the underlying mechanisms of transmigration and invasion remain to be elucidated. Improving our knowledge on these core processes might elevate the efficiency of stem cell therapy. Our aim was(More)
The renin-angiotensin system contributes to atherogenesis. Matrix metalloproteinases (MMP) are thought to participate in plaque destabilization through degradation of extracellular matrix. This study tested whether angiotensin II (ANG II) induces MMP in human vascular smooth muscle cells (SMC). ANG II induced expression of MMP-1, -3, and -9, but not of(More)
A Three-Facet Information D ealing with change is one of the most fundamental challenges facing IS professionals today. Business process restructuring, shifting alliances and new competitors , deregulation and globalization , legacy system migration, and new technology adoption, are but a few of the economical, organizational , and technological forces(More)
OBJECTIVE AND DESIGN Several studies report immuno-modulatory effects of endogenous IL-10 after trauma. This study investigates the effect of IL-10 administration on systemic and pulmonary inflammation in hemorrhagic shock. MATERIAL AND METHODS Male C57/BL6 mice (4-6 animals per group) were subjected to volume controlled hemorrhagic shock for 3 hrs(More)
BACKGROUND AND GOAL Postoperative loss of vision is a rare, but devastating complication after non-ocular surgery. It can occur partially or completely and may involve one or both eyes. Since its etiology has not yet been solved, the purpose of this review was to extract potential causes from the case collections reported to propose prophylactic measures.(More)
