[Acute respiratory distress due to Influenza A (H1N1) S-OIV and extracorporeal oxygenation: the benefit of a multidisciplinary care network].

Between August and September 2009, on Reunion Island, our Intensive Care Unit (ICU) treated several severe Influenza A (H1N1) S-OIV cases. We report the following case: a 23-year-old female patient with no prior medical history presented a severe respiratory distress that required high frequency oscillation ventilation and finally Extracorporeal Membrane Oxygenation (ECMO). She was hospitalized in the ICU for 41 days.

Treatment in hypertensive cardiac hypertrophy, II. Postreceptor events.

We investigated the effect of pharmacological treatment with captopril, nitrendipine, and captopril plus nitrendipine on myocardial heterologous adenylyl cyclase desensitization and the underlying postreceptor defects in spontaneously hypertensive rats (SHR). In myocardial membranes from SHR, stimulation of adenylyl cyclase with guanylylimido-diphosphate (P < .001) and forskolin (P < .

Treatment in hypertensive cardiac hypertrophy, I. Neuropeptide Y and beta-adrenoceptors.

In the present study, we investigated serum and myocardial neuropeptide Y concentrations as measures of sympathetic activity as well as myocardial beta-adrenoceptors and beta-adrenoceptor-stimulated adenylyl cyclase activity in spontaneously hypertensive rats (SHR). SHR and control rats at 10 weeks of age were kept on oral treatment with captopril, nitrendipine, or both for 20 weeks. Treatment only slightly reduced but did not normalize blood pressure and cardiac hypertrophy in SHR.

C-terminal modifications of pertussis toxin-sensitive G-protein alpha-subunits differentially affect immunoreactivity. Evidence against endogenous ADP-ribosylation in human heart, lung, thrombocytes and adipose tissue.

Immunochemical detection of pertussis toxin-sensitive guanine-nucleotide binding proteins has been suggested to represent the most direct approach to quantitate the protein than pertussis toxin-catalysed [32P]ADP-ribosylation. The latter technique is potentially hampered by pre-existing covalent modification of the C-terminus. However, limited data exist as to whether and in what way modifications of the C-terminus affect immunoreactivity of Gi alpha (alpha-subunit of the inhibitory G-protein of adenylyl cyclase).
