Zero-order interfacial enzymatic degradation of phospholipid tubules

Melting of phospholipid tubules.

Ion-induced interfacial dynamics of phospholipid monolayers.

Ion-induced interfacial dynamics of phospholipid monolayers were studied by various electrochemical techniques. The lipid monolayers were constructed by using the mercapto derivatives of natural lipids that were self-assembled directly onto gold electrode surfaces in a tails-down fashion. The supported lipid assemblies appeared to act as rather effective electron-tunneling barriers with K3Fe(CN...

Rapid Enzymatic Degradation

The effect of plasma on degradation of human growth hormonereleasing hormone (GRH) was examined in vitro and in vivo using high performance liquid chromatography (HPLC), radioimmunoassay (RIA), and bioassay. When GRH(1-44)-NH2 was incubated with human plasma, the t1/2 of total GRH immunoreactivity was 63 min (RIA). However, HPLC revealed a more rapid disappearance (t1/2, 17 min) ofGRH(144)-NH2 ...

Cyclosporin and mitochondrial phospholipid degradation.

0, in Table 1 ), since mitochondrial superoxide production increases linearly with 0, tension [XI . Whereas O2 had no effect on A q development at low Ca'+, A q dissipation at high Ca? + was markedly potentiated. Thus oxidative stress acted in strict synergism with Ca? + (as observed previously with hydroperoxides [ 5 ] ) . The adverse effects of Ca" and oxidative stress were abolished by 5 mM-...
