Reaction centers of the phototrophic bacterium Rhodopseudomonas palustris were introduced as proton motive force-generating systems in membrane vesicles of two anaerobic bacteria. Liposomes containing reaction center-light-harvesting complex I pigment protein complexes were fused with membrane vesicles of Streptococcus cremoris or Clostridium acetobutylicum by freeze-thawing and sonication. Ill...

Using a dual-task paradigm, two experiments tested whether aroused implicit motives would moderate the exertion of self-control in motive-related tasks. In Study 1, 67 participants first watched a power dialogue and were then asked to either enact the dialogue or simply reproduce it by writing it down. In Study 2, 74 participants performed either the frustrating or the simple version of an achi...

OBJECTIVE Previous research has shown that motive congruence, as observed in convergingly high or low scores on implicit and explicit motive measures, promotes well-being and health. Extending this individual perspective to the realm of couple relationships, the present investigation examined intra- and interpersonal effects of communal motive (in)congruence on relationship satisfaction and sta...

Susceptibility testing with a variety of structurally unrelated compounds showed that hefC in Helicobacter pylori is involved in multidrug efflux. This efflux was shown to depend on the proton motive force, as demonstrated by ethidium bromide accumulation experiments. Thus, H. pylori contains an active multidrug efflux mechanism.
