PURPOSE Activated protein C (APC) is the first anti-inflammatory drug to be approved for the treatment of severe sepsis. However, the underlying mechanisms are not completely elucidated. Therefore, the aim of our study was to evaluate the effects of APC on the microcirculation (mesenteric leukocyte-endothelial interaction, plasma extravasation) using(More)
Simulation replicates clinical experiences without patient risk; it remains uncommon in lower-income countries. We outline the creation of Rwanda's first centre for simulation and skills training. We secured funding for renovations, equipment and staff; curricula were developed, tested, and refined; local clinicians were trained to teach. In 13 months the(More)
BACKGROUND The eutectic mixture of local anaesthetics (EMLA) provides effective topical anaesthesia after a minimum of 60 to 90 min application. Since liposome-encapsulated tetracaine (LET) can provide rapid dermal penetration, the goal of this study was to compare the local anaesthetic effects of EMLA and LET in human volunteers after 60 min application.(More)
BACKGROUND Pulmonary administration of fentanyl solution can provide satisfactory but brief postoperative pain relief. Liposomes are microscopic phospholipid vesicles that can entrap drug molecules. Liposomal delivery of fentanyl has the potential to control the uptake of fentanyl by the lungs and thus provide sustained drug release. To demonstrate that(More)
INTRODUCTION Lectin-like oxidized low-density lipoprotein receptor-1 (LOX-1), the major endothelial receptor for oxidized low-density lipoprotein, is also involved in leukocyte recruitment. Systemic leukocyte activation in sepsis represents a crucial factor in the impairment of the microcirculation of different tissues, causing multiple organ failure and(More)
INTRODUCTION The brain is one of the first organs affected clinically in sepsis. Microcirculatory alterations are suggested to be a critical component in the pathophysiology of sepsis. The aim of this study was to investigate the effects of recombinant human activated protein C (rhAPC) on the pial microcirculation in experimental endotoxemia using(More)
This study investigated the effect of an intratracheal (i.t.) administration of a liposome-entrapped Delta9-tetrahydrocannabinol (LTHC) preparation on intraocular pressure (IOP) in nonanaesthetized Brown Norway rats. The ocular hypotensive effects of i.t. LTHC were compared to that of intraperitoneal (i.p.) LTHC administration. All i.t. LTHC doses >0.05(More)
INTRODUCTION Cannabinoid receptor 2 (CB2R) expression is upregulated during sepsis. However, there are conflicting results regarding the effects of CB2R modulation in the hyperinflammatory phase of the disease. The aim of this study was therefore to investigate the effects of CB2R manipulation on leukocyte activation within the intestinal microcirculation(More)
Co-activation of pro-coagulatory pathways in sepsis may result in disseminated intravascular coagulation and contributes to microvascular dysfunction. We investigated the effects of the direct thrombin inhibitor, argatroban (ARG), on the sepsis-induced impairment of the intestinal microcirculation (capillary perfusion, leukocyte adhesion) and the vascular(More)
KKP723 (KKP), a derivative of ampicillin, is a newly developed beta-lactam antibiotic. Using an experimental endotoxemia model, the intestinal microcirculation in four groups of animals were evaluated using intravital microscopy (IVM). The groups included were a control group, an endotoxemic group (15 mg/kg i.v. LPS from E. coli), an ampicillin (50 mg/kg(More)
