Glioblastoma multiforme (GBM) is the most frequent and aggressive primary brain tumor. GBM is formed by a very heterogeneous astrocyte population, neurons, neovascularization and infiltrating myeloid cells (microglia and monocyte derived macrophages). The IQGAP1 scaffold protein interacts with components of the cytoskeleton, cell adhesion molecules, and several signaling molecules to regulate cell morphology and motility, cell cycle and other cellular functions. IQGAP1 overexpression and delocalization has been observed in several tumors, suggesting a role for this protein in cell proliferation, transformation and invasion...

Infectious bursal disease virus (IBDV), a member of the Birnaviridae family, is responsible for a devastating immunosuppressive disease affecting juvenile domestic chickens. IBDV particles are naked icosahedrons enclosing a bipartite double-stranded RNA genome harboring three open reading frames (ORF). One of these ORFs codes for VP5, a non-structural polypeptide dispensable for virus replication in tissue culture but essential for IBDV pathogenesis. Using two previously described recombinant viruses, whose genomes differ in a single nucleotide, expressing or not the VP5 polypeptide, we have analyzed the role of this polypeptide during the IBDV replication process...

Cronobacter sakazakii is a foodborne pathogen that has been associated with severe infections mainly in neonates. The binding of this bacterium to host cell surfaces represents the first step in the pathogenesis of disease. An ELISA-based assay has been developed using a polyclonal antiserum against C. sakazakii to determine its adhesion to Caco-2 cells. The antiserum used recognised many of the outer membrane proteins of C. sakazakii. A positive correlation was found between the absorbance values obtained by ELISA and the number of bacteria adhered to cells determined by plate counting...

The importance of juvenile hormone regulating insect oogenesis suggests looking for genes whose expression is regulated by this hormone. SPARC is a calcium-binding glycoprotein that forms part of the extracellular membranes, which in vertebrates participates in bones mineralization or regulating cell proliferation in some cancer types. This large number of functions described for SPARC in different species might be related to the significant differences in its structure observed when comparing different species-groups...

BACKGROUND: Egg oral immunotherapy is effective but time consuming. OBJECTIVE: To assess the efficacy and safety of egg rush oral immunotherapy (ROIT) with a targeted dose equivalent to a raw egg white. METHODS: Thirty-three persistent egg allergic children confirmed by double-blind, placebo-controlled food challenge (DBPCFC) were randomized to receive egg ROIT immediately after randomization (ROIT1 group), or to continue an egg avoidance diet for 5 months after randomization (control group [CG])...

BACKGROUND: The objective of the study was to describe the baseline health-related quality of life (HRQOL) in a cohort of children and adolescents with type 1 diabetes mellitus (T1DM), and analyze its associated clinical and sociodemographic factors, assessing HRQOL through internet. METHODS: This was a descriptive study of 136 patients with T1DM from 5 hospitals in Catalonia, Spain (72 girls, mean age 13.4 years (range 8-19). Inclusion criteria were more than 6 months from diagnosis, more than 8 years old and without cognitive problems...

Upon TCR stimulation, CD4+ T lymphocytes release extracellular vesicles (EVs) containing microRNAs. However, no data are available on whether human CD4+ T cell subsets release EVs containing different pattern of microRNAs. The present work aimed at filling this gap by assessing the microRNA content in EVs released upon in vitro TCR stimulation of Th1, Th17 and T regulatory (Treg) cells. Our results indicate that EVs released by Treg cells are significantly different compared to those released by the other subsets...

INTRODUCTION: Patient safety aims to achieve healthcare free of damage. The World Health Organization indicates that this objective is achieved through communication, analysis, and prevention of adverse events in patients. Organizational culture has been identified as one of the main factors for interventions aimed to reduce medical errors; and an essential component of safety culture is the attitude of health professionals towards medical error. Attitudes can be improved through appropriate education in biomedical careers but its inclusion in Argentina is scarce...

BACKGROUND: Studies evaluating the relationship between soluble transferrin receptor (sTfR), a biomarker inversely related to body iron stores, and risk of type 2 diabetes mellitus (T2DM) are scarce and inconclusive. Furthermore, sTfR concentrations have been observed to be significantly higher in obese than in non-obese individuals. Therefore, the aim of the present study was to assess the relationship between sTfR and the risk of T2DM in obese and non-obese subjects. DESIGN: A nested case-control study of 153 cases of newly diagnosed diabetic subjects, 73 obese and 80 non-obese, and 306 individually matched-controls, 138 obese and 166 non-obese, who did not develop T2DM for a median 6-year follow-up (interquartile range: 3...

BACKGROUND: Refractory chronic migraine affects approximately 4% of the population worldwide and results in severe pain, lifestyle limitations, and decreased quality of life. Occipital nerve stimulation (ONS) refers to the electric stimulation of the distal branches of greater and lesser occipital nerves; the surgical technique has previously been described and has demonstrated efficacy in the treatment of a wide variety of headache disorders. OBJECTIVES: The aim of this study is to evaluate the long-term efficacy and tolerability of ONS for medically intractable chronic migraine...

The old-for-old allocation policy used for kidney transplantation (KT) has confirmed the survival benefit compared to remaining listed on dialysis. Shortage of standard donors has stimulated the development of strategies aimed to expand acceptance criteria, particularly of kidneys from elderly donors. We have systematically reviewed the literature on those different strategies. In addition to the review of outcomes of expanded criteria donor (ECD) or advanced age kidneys, we assessed the value of the Kidney Donor Profile Index (KDPI) policy, preimplantation biopsy, dual KT, machine perfusion and special immunosuppressive protocols...

Little is known about the metabolome fingerprint of pulse consumption. The study of robust and accurate biomarkers for pulse dietary assessment has great value for nutritional epidemiology regarding health benefits and their mechanisms. To characterize the fingerprinting of dietary pulses (chickpeas, lentils and beans), spot urine samples from a subcohort from the PREDIMED study were stratified, using a validated food frequency questionnaire. Non-pulse consumers (≤ 4 g/day of pulse intake) and habitual pulse consumers (≥ 25 g/day of pulse intake) were analysed using a 1H-NMR metabolomics approach combined with multi- and univariate data analysis...

Hospital discharge criteria for the pre-term newborn are mainly based on physiological competences (thermoregulation, respiratory stability, and feeding skills), although family support and ability to care for the baby, as well as a well-planned discharge are also cornerstones to ensure a successful discharge. In this article, the Committee of Standards of the Spanish Society of Neonatology reviews the current hospital discharge criteria in order for it to be useful as a clinical guide in Spanish neonatal units...

Symmetrical thalamic calcification or bilateral symmetrical thalamic gliosis presents at delivery with hypertonia, fixed flexion contractures and prominent bulbar signs, without preceding perinatal asphyxia. At post-mortem, there is evidence of bilateral symmetrical selective thalamic neuronal encrustation and gliosis. To date, 27 cases are published with no underlying diagnosis identified. Two affected children from singleton pregnancies were reported and therefore, a genetic cause proposed. No previous reports have performed genetic testing to confirm or reject this hypothesis...
