BACKGROUND Antibiotic resistance among microbes urgently necessitates the development of novel antimicrobial agents. Since ancient times, honey has been used successfully for treatment of infected wounds, because of its antibacterial activity. However, large variations in the in vitro antibacterial activity of various honeys have been reported and hamper(More)
Induced hypothermia after cardiopulmonary resuscitation provides organ protection and is currently considered standard of care in clinical practice. An increasing number of reports indicate that induced hypothermia is also beneficial in other conditions of hypoxia-induced organ injury, including brain injury, intestinal ischaemia-reperfusion injury and(More)
Acute lung injury is characterized by an exaggerated inflammatory response and a high metabolic demand. Mechanical ventilation can contribute to lung injury, resulting in ventilator-induced lung injury (VILI). A suspended-animation-like state induced by hydrogen sulfide (H2S) protects against hypoxia-induced organ injury. We hypothesized that suspended(More)
Organ failure is associated with increased mortality and morbidity in patients with systemic inflammatory response syndrome. Previously, we showed that a short course of infusion of a hydrogen sulfide (H(2)S) donor reduced metabolism with concurrent reduction of lung injury. Here, we hypothesize that prolonged H(2)S infusion is more protective than a short(More)
BACKGROUND Critically ill patients frequently develop acute lung injury (ALI). Disturbed alveolar fibrin turnover, a characteristic feature of ALI, is the result of both activation of coagulation and inhibition of fibrinolysis. Nebulized fibrinolytic agents could exert lung-protective effects, via promotion of fibrinolysis as well as anti-inflammation. (More)
Mechanical ventilation has the potential to cause lung injury, and the role of complement activation herein is uncertain. We hypothesized that inhibition of the complement cascade by administration of plasma-derived human C1-esterase inhibitor (C1-INH) prevents ventilation-induced pulmonary complement activation, and as such attenuates lung inflammation and(More)
A suspended animation-like state has been induced in rodents with the use of hydrogen sulfide, resulting in hypothermia with a concomitant reduction in metabolic rate. Also oxygen demand was reduced, thereby protecting against hypoxia. Several therapeutic applications of induction of a hibernation-like state have been suggested, including(More)
Sepsis is characterized by a generalized inflammatory response and organ failure, associated with mitochondrial dysfunction. Hydrogen sulfide donor NaHS has anti-inflammatory properties, is able to reduce metabolism and can preserve mitochondrial morphology and function. Rats were challenged with live Streptococcus pneumonia or saline and infused with NaHS(More)
BACKGROUND The innate immune response is important in ventilator-induced lung injury (VILI) but the exact pathways involved are not elucidated. The authors studied the role of the intracellular danger sensor NLRP3 inflammasome. METHODS NLRP3 inflammasome gene expression was analyzed in respiratory epithelial cells and alveolar macrophages obtained from(More)
In the era of lung-protective mechanical ventilation using limited tidal volumes, higher respiratory rates are applied to maintain adequate minute volume ventilation. However, higher respiratory rates may contribute to ventilator-induced lung injury (VILI). Induced hypothermia reduces carbon dioxide production and might allow for lower respiratory rates(More)
