Effect of the oxygen potential
-
The objective of this work is to experimentally investigate the effect of the oxygen potential on the fuel and FP chemical behaviour in conditions representative of a severe accident. More specifically, the speciation of Cs, Mo and Ba is investigated.

This paper reports the results obtained using the osmotic stress method applied to the purified cathodic and anodic hemoglobins (Hbs) from the catfishHoplosternum littorale, a species that displays facultative accessorial air oxygen-ation. We demonstrate that water potential affects the oxy-gen affinity ofH. littoraleHbs in the presence of an inert solute (sucrose). Oxygen affinity increases when water activity increases, indicating that water molecules stabilize thehigh-affinitystateof theHb.

3,3¢-Dipropyl-2,2¢-thiadicarbocyanine iodide [DiS-C3 (5)], often used as a tracer dye to assess the mitochondrial mem-brane potential, was investigated in detail regarding its effects on the structure and function of isolated mitochon-dria. As reported previously, DiS-C3(5) had an inhibitory effect on NADH-driven mitochondrial electron transfer. On the contrary, in the presence of inorganic phosphate, DiS-C3(5) showed dose-dependent biphasic effects on mito-chondria energized by succinate. At higher concentrations, such as 50lM,DiS-C3(5) acceleratedmitochondrial oxygen consumption. ...

Inhibition of the mitochondrial adenine nucleotide translocator (ANT) by long-chain acyl-CoA esters has been proposed to contribute to cellular dys-function in obesity and type 2 diabetes by increasing formation of reactive oxygen species and adenosine via effects on the coenzyme Q redox state, mitochondrial membrane potential (Dw) and cytosolic ATP concentrations.
