Respiratory distress syndrome caused by influenza H1N1 in a patient with a simultaneous pancreas-kidney transplantation.

Adult respiratory distress syndrome is a severe respiratory failure due to noncardiogenic pulmonary edema with high mortality rates (50-70%). The most common etiology of respiratory distress is sepsis, but it may also be caused by several of the immunosuppressants prescribed in transplantation. In the last year, influenza H1N1 virus infection has become more relevant.

Drug uptake, lipid rafts, and vesicle trafficking modulate resistance to an anticancer lysophosphatidylcholine analogue in yeast.

The ether-phospholipid edelfosine, a prototype antitumor lipid (ATL), kills yeast cells and selectively kills several cancer cell types. To gain insight into its mechanism of action, we performed chemogenomic screens in the Saccharomyces cerevisiae gene-deletion strain collection, identifying edelfosine-resistant mutants. LEM3, AGP2, and DOC1 genes were required for drug uptake.

Encephalopathy caused by lanthanum carbonate.

Lanthanum carbonate is a nonaluminum, noncalcium phosphate-binding agent, which is widely used in patients with end-stage chronic kidney disease. Until now, no significant side-effects have been described for the clinical use of lanthanum carbonate, and there are no available clinical data regarding its tissue stores. Here we report the case of a 59-year-old patient who was admitted with confusional syndrome.

Cytotoxicity of an anti-cancer lysophospholipid through selective modification of lipid raft composition.

Edelfosine is a prototypical member of the alkylphosphocholine class of antitumor drugs. Saccharomyces cerevisiae was used to screen for genes that modulate edelfosine cytotoxicity and identified sterol and sphingolipid pathways as relevant regulators. Edelfosine addition to yeast resulted in the selective partitioning of the essential plasma membrane protein Pma1p out of lipid rafts.
