Rounded atelectasis after exposure to refractory ceramic fibres (RCF).

Background: Refractory Ceramic fibres (RCF) are man-made mineral fibres used in high performance thermal insulation applications. Analogous to asbestos fibres, RCF are respirable, show a pleural drift and can persist in human lung tissue for more than 20 years after exposure. Pleural changes such as localised or diffuse pleural thickening as well as pleural calcification were reported.

Efficacy of an extracorporeal endotoxin adsorber system during hyperdynamic porcine endotoxemia.

Background: Endotoxemia is a crucial factor in the pathogenesis of sepsis. Elimination of endotoxin is aimed at the reduction of sepsis-related morbidity and lethality. The objective of this study was to examine the impact of an endotoxin adsorber on hemodynamics, O(2) exchange and metabolism during resuscitated porcine endotoxemia.

Pathogen specific cytokine release reveals an effect of TLR2 Arg753Gln during Candida sepsis in humans.

Toll-like receptors (TLRs) are crucial pattern-recognition receptors (PRRs) for activation of innate and adapted immunity. TLR2 heterodimerizes with TLR1 or TLR6 to recognize multiple pathogen-associated molecular patterns (PAMPs) of fungi, Gram-positive pathogens, and mycobacteria. Receptor activation culminates in monocyte, T-helper (Th)1, and Th2 cytokine release.

The role of C5a in the innate immune response after experimental blunt chest trauma.

The inflammatory response after severe blunt chest trauma often leads to acute lung injury and acute respiratory distress syndrome which are associated with high mortality rates. Whereas the role of innate immunity in acute lung injury has been broadly investigated, the immune response after blunt chest trauma is still poorly understood. Therefore, the role of complement and neutrophils was determined in bilateral lung injury induced by a single blast wave.
