    The problem of substance abuse impacts the Hispanic/Latino youth population. In some cases, subpopulations of the Hispanic/Latino population suffer higher rates of substance use than do other groups. While the science of prevention in the general population and the rigorous study of substances abuse prevention programs have flourished over the past few decades, there continues to be a limited body of knowledge regarding substance abuse prevention that is culturally specific or tailored to Hispanic/Latinos. One promising area is the study of risk and protective factors which finds that acculturation stress, among others, plays a key role in the development of substance use and other behavioral problems among youth. Stress experiences related to discrimination, immigration, parent–child cultural differences all play a role in disrupting normative development and subsequent risk-taking behavior. Culturally focused prevention models such as Familia Adelante show promise in helping reduce acculturation-based risk and increasing individual and family resilience. This chapter will address many of the aforementioned issues and will provide direction for future prevention research for Hispanic/Latinos

    Integrative OMICS Data-Driven Procedure Using a Derivatized Meta-Analysis Approach

    The wealth of high-throughput data has opened up new opportunities to analyze and describe biological processes at higher resolution, ultimately leading to a significant acceleration of scientific output using high-throughput data from the different omics layers and the generation of databases to store and report raw datasets. The great variability among the techniques and the heterogeneous methodologies used to produce this data have placed meta-analysis methods as one of the approaches of choice to correlate the resultant large-scale datasets from different research groups. Through multi-study meta-analyses, it is possible to generate results with greater statistical power compared to individual analyses. Gene signatures, biomarkers and pathways that provide new insights of a phenotype of interest have been identified by the analysis of large-scale datasets in several fields of science. However, despite all the efforts, a standardized regulation to report large-scale data and to identify the molecular targets and signaling networks is still lacking. Integrative analyses have also been introduced as complementation and augmentation for meta-analysis methodologies to generate novel hypotheses. Currently, there is no universal method established and the different methods available follow different purposes. Herein we describe a new unifying, scalable and straightforward methodology to meta-analyze different omics outputs, but also to integrate the significant outcomes into novel pathways describing biological processes of interest. The significance of using proper molecular identifiers is highlighted as well as the potential to further correlate molecules from different regulatory levels. To show the methodology's potential, a set of transcriptomic datasets are meta-analyzed as an example

    El presente trabajo se desarrolló con la finalidad de investigar la relación de la variable clima organizacional con la variable satisfacción laboral de los docentes de las Instituciones Educativas del Nivel secundario de la RED 4 UGEL 03, asimismo el tiempo empleado en total para el proceso de investigación fue de cuatro meses, desde agosto hasta diciembre del 2019. El método utilizado fue el cuantitativo y se aplicó el diseño no experimental, transversal, descriptivo y correlacional. La muestra estuvo conformada por un total de 90 docentes. Los instrumentos de investigación empleados fuerondos listas de cotejo, los cuales fueron previamente validados y sometidos a análisis dee fiabilidad; los resultados se procesaron con estadística descriptiva e inferencia en un paquete estadístico y se concluyó que que existe relación directa, baja y significativa entre clima organizacional y satisfacción laboral (r = ,250 y sig = ,017) de los docentes de las instituciones educativas nivel secundario de la RED 04 de la UGEL 03

    Modelling liver cancer microenvironment using a novel 3D culture system

    Full text link
    The tumor microenvironment and its contribution to tumorigenesis has been a focal highlight in recent years. A two-way communication between the tumor and the surrounding microenvironment sustains and contributes to the growth and metastasis of tumors. Progression and metastasis of hepatocellular carcinoma (HCC) have been reported to be exceedingly influenced by diverse microenvironmental cues. In this study, we present a 3D-culture model of liver cancer to better mimic in vivo tumor settings. By creating novel 3D co-culture model that combines free-floating and scaffold-based 3D-culture techniques of liver cancer cells and fibroblasts, we aimed to establish a simple albeit reproducible ex vivo cancer microenvironment model that captures tumor-stroma interactions. The model presented herein exhibited unique gene expression and protein expression profiles when compared to 2D and 3D mono-cultures of liver cancer cells. Our results showed that in vivo like conditions cannot be mimicked by simply growing cancer cells as spheroids, but by co-culturing them with 3D fibroblast with which they were able to crosstalk. This was evident by the upregulation of several pathways involved in HCC, and the increase in secreted factors by co-cultured cancer cells, many of which are also involved in tumor-stroma interactions. Compared to the conventional 2D culture, the proposed model exhibits an increase in the expression of genes associated with development, progression, and poor prognosis of HCC. Our results correlated with an aggressive outcome that better mirrors in vivo HCC, and therefore, a more reliable platform for molecular understanding of HCC
