All living cells routinely expel Na(+) ions, maintaining lower concentration of Na(+) in the cytoplasm than in the surrounding milieu. In the vast majority of bacteria, as well as in mitochondria and chloroplasts, export of Na(+) occurs at the expense of the proton-motive force. Some bacteria, however, possess primary generators of the transmembrane electrochemical gradient of Na(+) (sodium-mot...

Galactose transport was studied in membrane vesicles, prepared by fusion of plasma membranes from the yeast Kluyveromyces marxianus with proteoliposomes containing beef heart cytochrome c oxidase as a proton-motive force-generating system. Sugar transport studies performed under nonenergized conditions revealed that, even at high protein to phospholipid ratios, not all vesicles contained a D-ga...

Infections with Mycobacterium tuberculosis are substantially increasing on a worldwide scale and new antibiotics are urgently needed to combat concomitantly emerging drug-resistant mycobacterial strains. The diarylquinoline TMC207 is a highly promising drug candidate for treatment of tuberculosis. This compound kills M. tuberculosis by binding to a new target, mycobacterial ATP synthase. In thi...

If you ask most medical school deans if they have a course, program, or center doing bioethics, they will enthusiastically assure you that they do. And their enthusiasm for bioethics grows exponentially in proportion to their interest in showing that they are doing something about managing research ethics issues at their institutions. The same can be said about the entire biomedical research es...

Implicit motive research has shown that implicit motives are important predictors of behavior and well-being. However, little is known about the interrelationship between the different implicit motives measures frequently applied. We aimed to shed light on the convergent validity of three implicit motive measures and wanted to test their assumed statistical independence from three explicit moti...

We have integrated the basic psychological needs approach from self-determination theory with motive disposition theory in order to enhance the prediction of flow experience in sports. We hypothesize that an environment that enables people to fulfill their basic psychological needs for competence and social relatedness results in flow.Additionally,we assume that the effect of competence need sa...

All picture stimuli described in this chapter are available upon request from the authors. Measuring implicit motives 2 Measuring implicit motives Over the past ten years, the field of personality psychology has seen a resurgence of interest in implicit motives, nonconscious motivational needs that orient, select, and energize behavior (McClelland, 1987). This renewed interest has led to signif...

The motive associated to the second Symanzik polynomial of double-box two-loop Feynman graph with generic masses and momenta is shown be an elliptic curve.

X k=1 z 0k A0;k(z M)Mi01(z M): (41) This formula makes transparent exactly what happens in a recursive computation of the correlation functions. At every stage i, we have the Z-transform at points M 0i n of the appropriate function. In going to the (i + 1)st stage, the rst term Mi01(z M) ensures that values at the previous stage are retained at the even points, while the second term interpolate...
