Effect of an electric field on a floating lipid bilayer: A neutron reflectivity study.

We present here a neutron reflectivity study of the influence of an alternative electric field on a supported phospholipid double bilayer. We report for the first time a reproducible increase of the fluctuation amplitude leading to the complete unbinding of the floating bilayer. Results are in good agreement with a semi-quantitative interpretation in terms of negative electrostatic surface tension.

[Emphysematous pyelonephritis].

Pyelonephritis is a frequent infection of variable severity. Mortality is low since the era of antibiotics. Emphysematous pyelonephritis is however a rare but life threatening form of kidney infection, which affect more frequently diabetic subjects, characterized by gas producing bacteria. These gaseous lesions can be localized in the renal parenchyma or in the perirenal or retroperitoneal space. Diagnosis became easier with the advent of CT scan. Treatment usually requires surgery and antibiotics. We report a case of emphysematous pyelonephritis in a diabetic patient. The CT scan strongly suggested the diagnosis which was confirmed per-operatively. Proteus mirabilis is exceptionally described in emphysematous pyelonephritis.
