Under most circumstances the complexity of such nonequilibrium systems requires a number of approximations to make theoretical descriptions tractable. In particular, it is often assumed that spatially separated components of a system thermalize with their immediate surroundings, although the global state of the system is out of equilibrium. This powerful assumption reduces the complexity of nonequilibrium systems to the local application of well-founded equilibrium concepts. While this technique appears to be consistent for the description of some phenomena, we show that it fails for quantum friction by underestimating by approximately 80\% the magnitude of the drag force. Our results show that the correlations among the components of driven, but steady-state, quantum systems invalidate the assumption of local thermal equilibrium, calling for a critical reexamination of this approach for describing the physics of nonequilibrium systems.}, language = {en} } @article{IntravaiaBehuninHenkeletal.2016, author = {Intravaia, F. and Behunin, R.

Using general theoretical arguments, we show that the Markov approximation can lead to erroneous predictions of such phenomena with regard to both strength and functional dependencies on system parameters. In particular, we show that the long-time power-law tails of two-time dipole correlations and their corresponding low-frequency behavior, neglected in the Markovian limit, affect the prediction of the force. Our findings highlight the importance of non-Markovian effects in dispersion interactions.}, language = {en} } @article{HoieMorgensternGruenwaldetal.2005, author = {Hoie, Lars H. and Morgenstern, E.

It has not been conclusively answered, whether and to what extent other soy constituents may also contribute to this effect. Objective To investigate the change in blood lipid levels after application of two soy-based supplements containing soy protein either without (SuproSoy(R)) or with (Abacor(R)) soy fiber and phospholipids in a randomized placebo-controlled triple-armed study. Methods 121 hypercholesterolemic adults ( 66 females, 55 males) were recruited and randomly assigned to one of three treatments. Over 8 weeks they received daily either 25 g soy protein ( as a component of the supplements Abacor(R) or SuproSoy(R)) or 25 g milk protein ( as a component of placebo). Serum lipids were measured at baseline and after 4, 6 and 8 weeks. Results After 8 weeks of supplementation total cholesterol levels were reduced by 8.0 +/- 9.6\% (Abacor(R)) and 3.4 +/- 8.3\% (SuproSoy(R)); LDL cholesterol levels by 9.7 +/- 11.7\% ( Abacor(R)) and 5.4 +/- 11.6\% ( SuproSoy(R)); and Apolipoprotein B levels by 6.9 +/- 14.6\% (Abacor(R)) and 4.0 +/- 12.4 \% (SuproSoy(R)). Serum levels of HDL cholesterol and triglycerides remained unchanged. Conclusions A preparation combining isolated soy protein with soy fibers and phospholipids showed twice the lipid-lowering effect of a preparation containing isolated soy protein alone. Therefore, such soy-based supplements can be useful in reducing the cardiovascular risk}, language = {en} } @article{KressJarrinThuroffetal.2004, author = {Kress, H. and Jarrin, A. and Thuroff, E. and Saunders, R. and Weise, C. and Schmidt am Busch, Marcel and Knapp, E.

The Kil-1 gene is expressed exclusively in prepupal salivary glands. Using a size mutant of the KIL-1 protein and MALDI-TOF analysis, we demonstrate that during pupation this protein is released from the prepupal salivary glands into the pupation fluid covering the surface of the pupa. 3-D- structure predictions are consistent with the known crystal structure of the human Kunitz type protease inhibitor 2KNT. This is the first experimental proof for the extra-corporal presence of a distinct Drosophila prepupal salivary gland protein. Possible functions of KIL-1 in the context of the control of proteolytic activities in the pupation fluid are discussed. (C) 2004 Elsevier Ltd.

The comparison group (CG) included 92 asthmatic children and adolescents receiving standard medical treatments. Patients were aged between 8 and 16 years and were predominantly male. The health-related quality of life was measured with the German version of the "Paediatric Asthma Quality of Life Questionnaire." Interviews were carried out for IG 2 weeks before the commencement of their inpatient stay and 1 year after their stay ended. The same time schedule was carried out for CG. All patients reported a mild to moderate impairment of their quality of life. Girls described a slightly lower quality of life than boys. With increasing asthma severity, quality of life decreased. Inpatients described a lower quality of life than CG at enrollment. Inpatient rehabilitation resulted in a greater improvement of quality of life over time for IG than for CG. Gender and severity status had no effect on this time course. The only modestly affected quality of life may reflect the good adaptation to the disease and medical treatment. Children and adolescents in the IG recorded improvements in their quality of life. Differences in quality of life based on gender and disease severity were not shown to influence the improvements. In summary, inpatient rehabilitation results in an improvement of health-related quality of life.
