We have obtained the magnetic field dependence of static ferromagnetic correlations in nanocrystalline electrodeposited Co and Ni by means of the correlation function of the spin misalignment, determined from small-angle neutron scattering data. The approach yields a correlation length lC, which is a measure for the spatial extent of inhomogeneities in the magnetization distribution. The correlation length depends strongly on the applied magnetic field with values ranging from 94 nm in nanocrystalline Co at low fields to about 15 nm at saturation. The results for lC indicate that in Co the main source of nonuniformity in the spin system is the anisotropy field of each individual crystallite, whereas in nanocrystalline Ni the main sources of spin disorder originate from twin faults or from the defect cores of grain boundaries.

The phosphatidylinositol 3-kinase/Akt pathway plays an important role in the signaling of insulin and other growth factors, which reportedly attenuate the interleukin-6 (IL-6)-mediated stimulation of acute phase plasma protein genes. We investigated the effect of the protein kinase Akt on IL-6-mediated transcriptional activation. The transient expression of constitutively active Akt inhibited the IL-6-dependent activity of the alpha(2)-macroglobulin promoter in HepG2 cells, whereas expression of an inactive mutant of phosphatidylinositol-dependent kinase 1 had the opposite effect. Since Akt is known to regulate gene expression through inactivation of the transcription factor FKHR (forkhead in rhabdomyosarcoma), we examined the effect of FKHR on STAT3-mediated transcriptional regulation. Indeed, the overexpression of FKHR specifically enhanced the activity of STAT3-dependent promoters but not that of a STAT5-responsive promoter. The effect of FKHR required the presence of functional STAT3 and was abrogated by the expression of dominant negative STAT3 mutants. Furthermore, FKHR and STAT3 were shown to coimmunoprecipitate and to colocalize in the nuclear regions of IL-6-treated HepG2 cells. Our results indicate that FKHR can modulate the IL-6-induced transcriptional activity by acting as a coactivator of STAT3. [less ▲]

The paper analyzes the mechanisms by which policies aiming at downsizing the labour force (like early retirement policies) may in fact lead to lower employment levels, even though the equilibrium unemployment rate is decreased. Numerical examples suggest that job losses may be potentially important, even in the case where early retirements are concentrated among groups with high unemployment levels (low-skilled workers). The model takes into account the effects coming from imperfect competition and wage negotiations, as well as those coming from frictions and matching difficulties in an economy with continuous job creations and destructions. Reducing the labour force by promoting early retirement induces in the long run an increase in labour costs, either directly through the effect of unemployment on wages, or indirectly via the effect of unemployment on hiring difficulties.

We urgently need animal models to study infectious disease. Mice are susceptible to a similar range of microbial infections as humans. Marked differences between inbred strains of mice in their response to pathogen infection can be exploited to analyse the genetic basis of infections. In addition, the genetic tools that are available in the laboratory mouse, and new techniques to monitor the expression of bacterial genes in vivo, make it the principal experimental animal model for studying mechanisms of infection and immunity.

Signal transduction through cytokine receptors is mediated mainly by non-covalently associated Jak tyrosine kinases. By confocal microscopy, the cytokine receptor gp130 and Jak1, fused with either yellow (YFP) or cyan (CFP) fluorescent protein, were found to be colocalized predominantly at intracellular vesicular structures and at the plasma membrane. Quantitative fluorescence recovery after photobleaching (FRAP) analysis at the plasma membrane revealed equal mobilities for gp130-YFP and Jak1-YFP. Thus, Jak1-YFP diffuses like a transmembrane protein indicating that membrane-bound Jak1 does not exchange rapidly with cytosolic Jaks. Applying a novel dual-color FRAP approach we found that immobilization of gp130-CFP by a pair of monoclonal antibodies led to a corresponding immobilization of co-transfected Jak1-YFP. We conclude from these findings that Jak1, once bound to a gp130 molecule, does not exchange between different receptors at the plasma membrane neither via the cytoplasmic compartment nor via a membrane-associated state.

We present a variational Expectation-Maximization algorithm to learn probabilistic mixture models. The algorithm is similar to Kohonen's Self-Organizing Map algorithm and not limited to Gaussian mixtures. We maximize the variational free-energy that sums data log-likelihood and Kullback-Leibler divergence between a normalized neighborhood function and the posterior distribution on the components, given data. We illustrate the algorithm with an application on word clustering. [less ▲]
