Recently, two proteins of the S100 protein family, the myeloid-related calcium-binding proteins MRP-8 and MRP-14 have been implicated in the Ca2+-induced activation of the neutrophil NADPH oxidase (NOX2) but the mechanism underlying this process remains unclear. In this study, the role of MRP-8/14 in the Ca2+-dependent regulation of NOX2 activity was characterized in neutrophil-like HL-60 cells using small interfering RNAs (siRNAs) to knock-down endogenous MRP-8 and/or MRP-14 expression. Real-time PCR and Western blot revealed that MRP-8 and MRP-14 expression was 20 times higher in dimethylsulfoxide-differentiated neutrophil-like HL-60 cells compared to quiescent HL-60 cells. Knock-down of MRP-8 and MRP-14 in differentiated HL-60 cells decreased protein levels by 30 and 45% respectively. The impact of the reduced MRP-8/14 protein expression on NOX2 activity was investigated by measuring fMLF-induced H2O2 production. In cells simultaneously transfected with MRP-8 and MRP14 siRNAs, H2O2 production was reduced by 50%, suggesting that both MRP-8 and MRP-14 are required for NOX2 activity; single knock-downs were inefficient. To elucidate the role of Ca2+ in MRP8/14, and consequently in NOX2 activation, siRNA-transfected cells were treated with the Ca2+ ionophore ionomycin prior to stimulation with PMA, a Ca2+-independent protein kinase C activator. PMA-induced H2O2 production was enhanced by ionomycin. This amplification of NOX2 activity was abolished by MRP8/14 knock-down, indicating that both MRP-8 and MRP-14 are necessary to regulate Ca2+-induced NOX2 activation. Taken together, our results suggest that the mechanism of MRPs activation is highly dependent on the increase of intracellular Ca2+ level for a full activation of NOX2. [less ▲]

In order to enter symbiosis with its legume partner, Sinorhizobium meliloti requires regulatory systems for the appropriate responses to its environment. For example, motility is required for the chemotactic movement of bacteria toward the compounds released by its host, and exopolysaccharides (EPS) are required for bacterial attachment to the root or for invasion of the infection thread. Previous research has shown that ExoR/ExoS/ChvI as well as the ExpR/Sin quorum-sensing system inversely regulate both motility and EPS production, although the regulation mechanisms were unknown. We were able to attribute the ExpR-mediated regulation of motility to the ability of ExpR to bind a DNA sequence upstream of visN when activated by N-acyl-homoserine lactone. Furthermore, MucR, previously characterized as a regulator of EPS production, also affected motility. MucR inhibited expression of rem encoding an activator of motility gene expression and, consequently, the expression of Rem-regulated genes such as flaF and flgG. Binding of MucR to the rem promoter region was demonstrated and a sequence motif similar to the previously identified MucR binding consensus was identified within this region. The swarming ability of S. meliloti Rm2011 was shown to depend on a functional ExpR/Sin quorum-sensing system and the production of both flagella and EPS. Finally, we propose a model for the coordination of motility and EPS synthesis in S. meliloti. [less ▲]

We report on the observation of real-time-resolved room temperature grain growth in nanocrystalline metals. We find that neither the time evolution of size can be modeled by standard growth theories nor are there any other systems aware to us that manifest a similar growth behaviour. We detect a transition from an initially self-similar slow growth to abnormal grain growth. Its onset seems to be associated with the simultaneous decrease of microstrain with increasing grain size. Abnormal grain growth is considered as a generic feature of nanocrystallinity but is a transient state since we observed in the late stage of coarsening, using orientational imaging microscopy, a monomodal grain size distribution. We empirically find a nonlinear-response-type of growth law which is in agreement with the observed coarsening kinetics. [less ▲]

In Zampunieris (2006) we proposed a new kind of learning management system, proactive LMS, designed to help users to better interact online by providing programmable, automatic, and continuous analyses of the users’ actions, augmented with appropriate actions initiated by the LMS itself. The proactive part of our LMS is based on a dynamic rules-based system. However, the main algorithm we proposed in order to implement the rules-running system suffers some efficiency problems. In this article, we propose a new version of the main rules-running algorithm that is based on lazy evaluation in order to avoid unnecessary and time-costly requests to the LMS database when a rule is not activated, that is, when its actions part will not be performed because preliminary check(s) failed.

Two areas in the human occipito-temporal cortex respond preferentially to faces: 'the fusiform face area' ('FFA') and the 'occipital face area' ('OFA'). However, it is unclear whether these areas have an exclusive role in processing faces, or if sub-maximal responses in other visual areas such as the lateral occipital complex (LOC) are also involved. To clarify this issue, we tested a brain-damaged patient (PS) presenting a face-selective impairment with functional magnetic resonance imaging (fMRI). The right hemisphere lesion of the prosopagnosic patient encompasses the 'OFA' but preserves the 'FFA' and LOC. Using fMRI-adaptation, we found a larger response to different faces than repeated faces in the ventral part of the LOC both for normals and the patient, next to her right hemisphere lesion. This observation indicates that following prosopagnosia, areas that do not respond preferentially to faces such as the ventral part of the LOC (vLOC) may still be recruited to subtend residual perception of individual faces.
