Owing to our lack of understanding of the factors that constitute protective immunity during natural infection with Mycobacterium tuberculosis (Mtb), there is an urgent need to identify host biomarkers that predict long-term outcome of infection in the absence of therapy. Moreover, the identification of host biomarkers that predict (in)adequate response to(More)
Hypotheses tests in bioinformatics can often be set in a tree structure in a very natural way, e.g. when tests are performed at probe, gene, and chromosome level. Exploiting this graph structure in a multiple testing procedure may result in a gain in power or increased interpretability of the results.We present the inheritance procedure, a method of(More)
Cajal Bodies are one of many specialised organelles contained in the eukaryotic cell nucleus, and are involved in a number of functions, including regulation of replication-dependent histone gene transcription. In normal diploid cells their number varies between 0 and 4 depending on the cell cycle phase, although in cancer cell lines their number is(More)
OBJECTIVE In the past years, the canonical Wnt/β-catenin signaling pathway has emerged as a critical regulator of cartilage development and homeostasis. In this pathway, glycogen synthase kinase-3β (GSK3β) down-regulates transduction of the canonical Wnt signal by promoting degradation of β-catenin. In this study we wanted to further investigate the role of(More)
We propose a multiple testing procedure controlling the false discovery rate. The procedure is based on a possibly data driven ordering of the hypotheses, which are tested at the uncorrected level q until a suitable number is not rejected. When the order is data driven, larger effect sizes are considered first, therefore selecting more interesting(More)
Female hormones are very important in regulating bone homeostasis; the drop of estrogen levels occurring at menopause is linked to a dramatic prevalence of bone resorption on formation. Only a small number of studies investigated the relationship between changes in circulating female sex hormones and the markers and mediators of bone homeostasis and they(More)
Anthropogenic emissions of carbon dioxide are leading to decreases in pH and changes in the carbonate chemistry of seawater. Ocean acidification may negatively affect the ability of marine organisms to produce calcareous structures while also influencing their physiological responses and growth. The aim of this study was to evaluate the effects of reduced(More)
Gaze shifts and fixations appear to be proactive in both action execution and observation. We investigated a dependency of anticipatory gaze behaviour by using a block stacking task. Blocks were rectangles depicted on a computer screen and the stacking movements were controlled via computer mouse. Subjects either had to execute the task or had to observe it(More)
Water acidification, temperature increases and changes in seawater salinity are predicted to occur in the near future. In such a global climate change (GCC) scenario, there is growing concern for the health status of both wild and farmed organisms. Bivalve molluscs, an important component of coastal marine ecosystems, are at risk. At the immunological(More)
Previous studies showed that using tools modifies the agent's body and space representation. However, it is still not clear which rules govern those remapping processes. Here, we studied the differential role played by the morpho-functional characteristics of a tool and the sensori-motor constraints that a tool imposes on the hand. To do so, we asked a(More)
