    Abstract Lipids are essential for cellular function and are tightly controlled at the transcriptional and post-transcriptional levels. Dysregulation of these pathways is associated with vascular diseases, diabetes, cancer, and several inherited metabolic disorders. MicroRNAs (miRNAs), in particular, are a family of post-transcriptional gene repressors associated with the regulation of many genes that encode proteins involved in multiple lipid metabolism pathways, thereby influencing their homeostasis. Thus, this class of non-coding RNAs (ncRNAs) has emerged as a promising therapeutic target for the treatment of lipid-related metabolic alterations. Most of these miRNAs act at an intracellular level, but in the past few years, a role for miRNAs as intercellular signaling molecules has also been uncovered since they can be transported in bodily fluids and used as potential biomarkers of lipid metabolic alterations. In this review, we point out the current knowledge on the miRNA signature in a lysosomal storage disorder associated with lipid dysfunction, Niemann-Pick type C, and discuss the potential use of miRNAs as biomarkers and therapeutic targets for RNA-based therapies.

    Abstract El presente estudio tuvo el objetivo de determinar la eficacia del programa educativo ¡Qué importante es tributar! orientado a desarrollar conocimientos y actitudes favorables sobre cultura tributaria en estudiantes de secundaria de una institución educativa privada de Juliaca. La investigación se enmarca en un diseño cuasi-experimental con evaluación pre y post intervención, en el cual los participantes fueron distribuidos en dos grupos: experimental (GE = 30) y control (GC = 30). En este caso, fue el GE quien recibió un total de 10 sesiones educativas distribuidas en 3 módulos: conocimientos, percepción y actitudes. Para determinar la eficacia del programa se aplicó un cuestionario que medía la cultura tributaria utilizada en una investigación similar y validada por expertos en educación financiera. Los resultados indican que antes de la intervención seis participantes del GE (20%) demostraron conocimientos sobre cultura tributaria a nivel bajo, 19 a nivel moderado (63.3%) y cinco a nivel alto (16.7%); luego de la intervención, ninguno demostró un nivel bajo, 19 un nivel moderado (63.3%) y 11 un nivel alto. Según la prueba de hipótesis, el estadístico t de student reveló diferencias significativas entre los puntajes hallados antes y después de la intervención (t = -7.509, p < .05), mientras que las diferencias en el grupo control fueron porcentuales mas no significativas (t = .648, p > .05). Se concluye que el programa educativo incrementó positivamente conocimientos, percepciones y actitudes favorables hacia la cultura tributaria en adolescentes, a fin de promover el cumplimiento ético de las obligaciones tributarias.

    Abstract Despite extensive research, the links between the accumulation of glycosaminoglycans (GAGs) and the clinical features seen in patients suffering from various forms of mucopolysaccharidoses (MPSs) have yet to be further elucidated. This is particularly true for the neuropathology of these disorders; the neurological symptoms are currently incurable, even in the cases where a disease-specific therapeutic approach does exist. One of the best ways to get insights on the molecular mechanisms driving that pathogenesis is the analysis of patient-derived cells. Yet, not every patient-derived cell recapitulates relevant disease features. For the neuronopathic forms of MPSs, for example, this is particularly evident because of the obvious inability to access live neurons. This scenario changed significantly with the advent of induced pluripotent stem cell (iPSC) technologies. From then on, a series of differentiation protocols to generate neurons from iPSC was developed and extensively used for disease modeling. Currently, human iPSC and iPSC-derived cell models have been generated for several MPSs and numerous lessons were learnt from their analysis. Here we review most of those studies, not only listing the currently available MPS iPSC lines and their derived models, but also summarizing how they were generated and the major information different groups have gathered from their analyses. Finally, and taking into account that iPSC generation is a laborious/expensive protocol that holds significant limitations, we also hypothesize on a tempting alternative to establish MPS patient-derived neuronal cells in a much more expedite way, by taking advantage of the existence of a population of multipotent stem cells in human dental pulp to establish mixed neuronal and glial cultures.

    Abstract Background: Life satisfaction as well as job satisfaction of teachers has a significant impact on educational outcomes.
    Objective: To evaluate a model of factors predicting life satisfaction through the mediating role of job satisfaction.
    Methods: This was a cross-sectional study, with a sample of 300 primary school teachers of both sexes (68% female, 32% male) and with a mean age of 42.52 years (SD = 10.04). They were administered the General Self-Efficacy Scale, the Satisfaction with Life Scale (SWLS), the Workload Scale (ECT), the Generic Job Satisfaction Scale, and the Organizational Commitment Questionnaire (OCQ). Structural equation modeling (SEM) was used for data analysis.
    Results: The SEM analysis found significant goodness-of-fit indices: (χ2 = 13.739; df = 5;
    Conclusion: The results confirm the importance of self-efficacy, organizational commitment, and workload in job satisfaction and overall life satisfaction of elementary education teachers. Job satisfaction acts as a mediator in this relationship. It is important to reduce workload and promote self-efficacy and organizational commitment to improve the well-being and satisfaction of teachers.

    Abstract Among the many lysosomal storage disorders (LSDs) that would benefit from the establishment of novel cell models, either patient-derived or genetically engineered, is mucopolysaccharidosis type II (MPS II). Here, we present our results on the establishment and characterization of two MPS II patient-derived stem cell line(s) from deciduous baby teeth. To the best of our knowledge, this is the first time a stem cell population has been isolated from LSD patient samples obtained from the dental pulp. Taking into account our results on the molecular and biochemical characterization of those cells and the fact that they exhibit visible and measurable disease phenotypes, we consider these cells may qualify as a valuable disease model, which may be useful for both pathophysiological assessments and in vitro screenings. Ultimately, we believe that patient-derived dental pulp stem cells (DPSCs), particularly those isolated from human exfoliated deciduous teeth (SHEDs), may represent a feasible alternative to induced pluripotent stem cells (iPSCs) in many labs with standard cell culture conditions and limited (human and economic) resources.

    Abstract Introduction: When it comes to disease modeling, countless models are available for Lysosomal Storage Diseases (LSD). Historically, two major approaches are well-established: in vitro assessments are performed in patient fibroblasts, while in vivo pre-clinical studies are performed in mouse models. Still, both platforms have a series of drawbacks. Thus, we implemented two alternative and innovative protocols to mimic a particular sub-group of LSDs, the Mucopolysaccharidoses both in vitro and in vivo.
    Methods: The first one relies on a non-invasive approach using dental pulp stem cells from deciduous teeth (SHEDs). SHEDs are multipotent neuronal precursors that can easily be collected. The second uses a state-of-the-art gene editing technology (CRISPR/Cas9) to generate zebrafish disease models.
    Results: Even though this is an ongoing project, we have already established and characterized two MPS II and one MPS VI SHED cell models. These cells self-maintain through several passages and can give rise to a variety of cells including neurons. Furthermore, all MPS-associated sub-cellular phenotypes we have assessed so far are easily observable in these cells. Regarding our zebrafish models, we have successfully knocked down both naglu and hgsnat and the first results we got from the behavioral analysis are promising ones, as we can observe altered activity and sleep patterns in the genetically modified fish. For this particular approach we chose MPS III forms as our target disorders, since their neurological features (hyperactivity, seizures and motor impairment) and lifespan decrease would be easily recognizable in zebrafish.
    Conclusion: Now that these methods are well-established in our lab, their potential is immense. On one hand, the newly developed models will be of ultimate value to understand the mechanisms underlying MPS sub-cellular pathology, which have to be further elucidated. On the other hand, they will constitute an optimal platform for drug testing in house. Also noteworthy, our models will be published as lab resources and made available for the whole LSD community.

    Abstract Background: The prevalence of childhood asthma has increased, although the rate of hospitalization for asthma seems to decrease. In Norway, the rate of hospital admission for childhood asthma from 1984 to 2000 increased. The aim of this study was to assess further trends in hospital admissions for childhood asthma up to 2010.
    Methods: A population-based study including children 1-13 yrs of age hospitalized for asthma during six periods from 1984/1985 to 2009/2010 in Rogaland, Norway, was performed. Medical records from 1536 admissions (1050 children) were studied; and gender, age, number of admissions, length of hospital stay, medications and symptoms were recorded.
    Results: For all age groups, the rate of admissions per 10.000 increased from 20.1 in 1984/85 to 33.7 in 1989/90, but declined to 14.4 in 2009/2010. Rates were highest in boys (OR 1.87; 95% CI: 1.69, 2.09), younger age groups (OR 2.51; 2.38, 2.64) and decreased from 1984 to 2010 (OR 0.92; 0.88, 0.94). The rates of readmissions were higher than for primary admissions (OR 1.33; 1.19, 1.47). From 1984 to 2010, there was an increased use of inhaled corticosteroids prior to admission (6 to 51%) and started at discharge (7 to 37%), and systemic steroids given during admission (19 to 83%).
    Conclusion: There has been a substantial decline in the rate of hospital admissions for childhood asthma after 1989/1990, with major differences between age groups and genders. The decline could be due to improved care of children with asthma or a real reduction in asthma exacerbations.
