Our paper presents the comparison of a machine-learnt and a manually constructed expert-rule-based biological event extraction system and some preliminary experiments to apply a negation and speculation detection system to further classify the extracted events. We report results on the BioNLP'09 Shared Task on Event Extraction evaluation datasets, and also(More)
STUDY QUESTION Are the quantitative and qualitative characteristics of semen samples of patients with testicular cancer (TC), prior to anticancer therapy, different from infertile oligozoospermic (IO) and normozoospermic (NZ) age-matched men? SUMMARY ANSWER Sperm concentration in TC patients was significantly decreased with no difference in estimated(More)
The effects of Alzheimer's disease-related beta-amyloid (Abeta) peptides on the N-methyl-D-aspartate (NMDA)-evoked cell firing rate were studied in hippocampal CA1 neurons of the rat. Extracellular single-unit recordings were combined with iontophoretic applications that allowed quantitative analyses of the interactions between Abeta peptides and NMDA(More)
The effects of orexin-monoaminergic compound interactions on vasopressin release were studied in 14-day neurohypophyseal cell cultures from adult rats, prepared by an enzymatic dissociation technique. The vasopressin contents of the supernatants were determined by radioimmunoassay. Following administration of either orexin-A or orexin-B in increasing doses,(More)
BACKGROUND Fluid challenges (FCs) are one of the most commonly used therapies in critically ill patients and represent the cornerstone of hemodynamic management in intensive care units. There are clear benefits and harms from fluid therapy. Limited data on the indication, type, amount and rate of an FC in critically ill patients exist in the literature. The(More)
INTRODUCTION Several single-center studies and meta-analyses have shown that perioperative goal-directed therapy may significantly improve outcomes in general surgical patients. We hypothesized that using a treatment algorithm based on pulse pressure variation, cardiac index trending by radial artery pulse contour analysis, and mean arterial pressure in a(More)
INTRODUCTION Postoperative care after oesophageal tumour resection holds a high risk of respiratory complications. We therefore aimed to determine the value of systemic inflammatory markers in predicting arterial hypoxaemia as the earliest sign of developing lung injury after oesophageal tumour resection. METHODS In a prospective observational study, 33(More)
OBJECTIVE The aim of this study was to investigate the short-term effect of fluid resuscitation with 4% modified fluid gelatine (GEL) versus 6% hydroxyethyl starch (HES) on haemodynamics and oxygenation in patients with septic shock and acute lung injury (ALI). DESIGN Prospective randomised clinical trial. SETTING Twenty-bed intensive care unit in a(More)
Monitoring hypovolemia is an everyday challenge in critical care, with no consensus on the best indicator or what is the clinically relevant level of hypovolemia. The aim of this experiment was to determine how central venous oxygen saturation (ScvO2) and central venous-to-arterial carbon dioxide difference (CO2 gap) reflect hypovolemia-caused changes in(More)
The effects of orexin-monoaminergic compound interactions on oxytocin release were studied in 14-day rat neurohypophyseal cell cultures prepared by an enzymatic dissociation technique. The oxytocin contents of the supernatants were determined by radioimmunoassay. Following the administration of orexin-A or orexin-B in increasing doses, significant changes(More)
