We address the specific role of cytoplasmic Ca(2+) overload as a cell death trigger by expressing a receptor-operated specific Ca(2+) channel, vanilloid receptor subtype 1 (VR1), in Jurkat cells. Ca(2+) uptake through the VR1 channel, but not capacitative Ca(2+) influx stimulated by the muscarinic type 1 receptor, induced sustained intracellular [Ca(2+)](More)
Citrus genus includes some of the most important cultivated fruit trees worldwide. Despite being extensively studied because of its commercial relevance, the origin of cultivated citrus species and the history of its domestication still remain an open question. Here, we present a phylogenetic analysis of the chloroplast genomes of 34 citrus genotypes which(More)
In this paper an optimal solution to the problem of determining both vehicle attitude and position using line-of-sight measurements is presented. The new algorithm is derived from a generalized predictive filter for nonlinear systems. This uses a one time-step ahead approach to propagate a simple kinematics model for attitude and position determination. The(More)
The massive use of Next-Generation Sequencing (NGS) technologies is uncovering an unexpected amount of variability. The functional characterization of such variability, particularly in the most common form of variation found, the Single Nucleotide Variants (SNVs), has become a priority that needs to be addressed in a systematic way. VARIANT (VARIant ANalyis(More)
Genomic experiments (e.g. differential gene expression, single-nucleotide polymorphism association) typically produce ranked list of genes. We present a simple but powerful approach which uses protein-protein interaction data to detect sub-networks within such ranked lists of genes or proteins. We performed an exhaustive study of network parameters that(More)
The molecular epidemiology of HIV-1 is constantly changing, mainly as a result of human migratory flows and the high adaptive ability of the virus. In recent years, Spain has become one of Europe's main destinations for immigrants and one of the western European countries with the highest rates of HIV-positive patients. Using a phylogeographic approach, we(More)
We studied 75 patients with non-hematological conditions from whom Aspergillus spp. were recovered from clinical specimens during the period March 2003 to August 2006. The patients were classified according to EORTC criteria and the presence of galactomannan (Platelia Aspergillus) in their sera was evaluated. Ten of these patients (13.3%) had proven or(More)
OBJECTIVES Microbiological strategies are necessary to help clinicians discontinue empirical antifungal therapy in patients with suspected invasive candidiasis. Culture methods and biomarkers each show low sensitivity. We analysed the value of combining different biomarkers as a decision-making tool for discontinuing empirical antifungal treatment. (More)
Patients with candidemia may have transient or catheter-related infections without involvement of deep tissues or deep-seated candidiasis. Clinical differentiation of these entities may not be evident with conventional microbiological and imaging methods. Our aim was to determine if the detection of Candida albicans germ tube-specific antibody (CAGTA) in(More)
Fas ligand (FasL) mediates both apoptotic and inflammatory responses in the immune system. FasL function critically depends on the different forms of FasL; soluble Fas ligand lacking the transmembrane and cytoplasmic domains is a poor mediator of apoptosis, whereas full-length, membrane-associated FasL (mFasL) is pro-apoptotic. mFasL can be released from T(More)
