Dendritic cells are involved in the initiation of both innate and adaptive immunity. To systematically explore how dendritic cells modulate the immune system in response to different pathogens, we used oligonucleotide microarrays to measure gene expression profiles of dendritic cells in response to Escherichia coli, Candida albicans, and influenza virus as(More)
Hardly anything is known about translational control of plant mitochondrial gene expression. Here, we provide evidence for differential translation of mitochondrial transcripts in Arabidopsis thaliana. We found that silencing of the nuclear RPS10 gene encoding mitochondrial ribosomal protein S10 disturbs the ratio between the small and large subunits of(More)
Various developments have taken place in GARFIELD over the last 2 years: the limitation to analytic potentials and 2-dimensional geometries is being lifted via interfaces with finite element programs such as [1]; detailed calculations of the electrostatic wire movements have been added; cluster generation has been enhanced considerably thanks to an(More)
Commercial interest is growing in biomimetic methods that employ self assembled mono-layers (SAMs) to produce biocompatible HA coatings on Ti-based orthopedic implants. Recently, separate studies have considered HA formation for various SAM surface functional groups. However, these have often neglected to verify crystallinity of the HA coating, which is(More)
Neutrophil extracellular traps (NETs), web-like DNA structures, provide efficient means of eliminating invading microorganisms but can also present a potential threat to its host because it is a likely source of autoantigens or by promoting bystander tissue damage. Therefore, it is important to identify mechanisms that inhibit NET formation. Neutrophil(More)
Most of text categorization research exploit bag-of-words text representation. However, such representation makes it very hard to capture semantic similarity between text documents that share very little or even no vocabulary. In this paper we present preliminary results obtained with a novel approach that combines well established kernel text classifiers(More)
Immune cells regulate cell surface receptor expression during their maturation, activation, and motility. Although many of these receptors are regulated largely at the level of expression, protease-mediated ectodomain shedding represents an alternative means of refashioning the surface of immune cells. Shedding is largely attributed to a family of a(More)
In this paper, a new definition of a right inverse of nonsquare parameter matrices is derived from MVC-related inverses of nonsquare polynomial matrices. The new definition is employed in a stabilizing state-space perfect control law for nonsquare LTI MIMO systems. A simulation example shows that the new inverse outperforms the classical minimum-norm right(More)
Secretory leukocyte protease inhibitor (SLPI), a ∼12kDa nonglycosylated cationic protein, is emerging as an important regulator of innate and adaptive immunity and as a component of tissue regenerative programs. First described as an inhibitor of serine proteases such as neutrophil elastase, this protein is increasingly recognized as a molecule that(More)
