Plasma and bronchoalveolar lavage fluid oxylipin levels in experimental porcine lung injury.

Inflammatory signaling pathways involving eicosanoids and other regulatory lipid mediators are a subject of intensive study, and a role for these in acute lung injury is not yet well understood. We hypothesized that oxylipin release from lung injury could be detected in bronchoalveolar lavage fluid and in plasma. In a porcine model of surfactant depletion, ventilation with hyperinflation was assessed.

Targeted delivery of antisense oligonucleotides to pancreatic β-cells.

Antisense oligonucleotide (ASO) silencing of the expression of disease-associated genes is an attractive novel therapeutic approach, but treatments are limited by the ability to deliver ASOs to cells and tissues. Following systemic administration, ASOs preferentially accumulate in liver and kidney. Among the cell types refractory to ASO uptake is the pancreatic insulin-secreting β-cell.

Scandinavian clinical practice guideline on fluid and drug therapy in adults with acute respiratory distress syndrome.

Background: The objective of the Scandinavian Society of Anaesthesiology and Intensive Care Medicine (SSAI) task force on fluid and drug therapy in adults with acute respiratory distress syndrome (ARDS) was to provide clinically relevant, evidence-based treatment recommendations according to standards for trustworthy guidelines.

Methods: The guideline was developed according to standards for trustworthy guidelines, including a systematic review of the literature and use of the GRADE methodology for assessment of the quality of evidence and for moving from evidence to recommendations.

Results: A total of seven ARDS interventions were assessed.

Optimisation of a simple method to transiently transfect a CHO cell line in high-throughput and at large scale.

Transient expression of heterologous proteins in mammalian systems is a powerful way to generate protein reagents quickly. However, it has historically suffered from poor yields in comparison to methods where the recombinant gene is stably integrated into the genome and high expressing clones isolated. Transient methods have been well described for HEK-based systems.

Percutaneously inserted long-term central venous catheters in pigs of different sizes.

Pigs are used for long-term biomedical experiments requiring repeated injections, infusions and collections of blood samples. Thus, it is necessary for vascular catheters to be indwelling to avoid undue stress to the animals and the use of restraints. We propose a refined model of percutaneous insertion of long-term central venous catheters to minimize the surgical trauma and postoperative complications associated with catheter insertion.
