Identification of viral infections in the prostate and evaluation of their association with cancer

<p>Abstract</p> <p>Background</p> <p>Several viruses with known oncogenic potential infect prostate tissue, among these are the polyomaviruses BKV, JCV, and SV40; human papillomaviruses (HPVs), and human cytomegalovirus (HCMV) infections. Recently, the Xenotropic Murine Leukemia Virus-related gammaretrovirus (XMRV) was identified in prostate tissue with a high prevalence observed in prostate cancer (PC) patients homozygous for the glutamine variant of the RNASEL protein (462Q/Q). Association studies with the R462Q allele and non-XMRV viruses have not been reported. We assessed associations between prostate cancer, prostate viral infections, and the RNASEL 462Q allele in Mexican cancer patients and controls.</p> <p>Methods</p> <p>130 subjects (55 prostate cancer cases and 75 controls) were enrolled in the study. DNA and RNA isolated from prostate tissues were screened for the presence of viral genomes. Genotyping of the RNASEL R462Q variant was performed by Taqman method.</p> <p>Results</p> <p>R/R, R/Q, and Q/Q frequencies for R462Q were 0.62, 0.38, and 0.0 for PC cases and 0.69, 0.24, and 0.07 for controls, respectively. HPV sequences were detected in 11 (20.0%) cases and 4 (5.3%) controls. XMRV and HCMV infections were detected in one and six control samples, respectively. The risk of PC was significantly increased (Odds Ratio = 3.98; 95% CI: 1.17-13.56, p = 0.027) by infection of the prostatic tissue with HPV. BKV, JCV, and SV40 sequences were not detected in any of the tissue samples examined.</p> <p>Conclusions</p> <p>We report a positive association between PC and HPV infection. The 462Q/Q RNASEL genotype was not represented in our PC cases; thus, its interaction with prostate viral infections and cancer could not be evaluated.</p

Descripción: El curso Introducción a los Negocios Internacionales, es el primer curso de línea en la carrera de Administración y Negocios Internacionales de carácter teórico-práctico dirigido a los estudiantes del primer ciclo con el objetivo de brindar una visión global y actual del mundo y de los negocios internacionales. Propósito: El curso Introducción a los Negocios Internacionales es relevante porque busca desarrollar en el estudiante la capacidad de ser consciente que los NNII en la actualidad se desenvuelven dentro del contexto dinámico de las tecnologías de la información y la creciente globalización; así como desarrollar su visión comercial, a partir del conocimiento de los entornos con variables endógenas, en los que se presentan las diferentes fuerzas internas que si son controlables y los entornos con variables exógenas, en los que se presentan las fuerzas no controlables o externas. El curso desarrolla las competencias generales Pensamiento Innovador y Comunicación Oral, en el nivel de logro 1 y la competencia específica Evaluación de Oportunidades Internacionales en el nivel de logro

Introducción a los Negocios Internacionales - AN78 - 202102

Descripción: Es el primer curso de línea en la carrera de Administración y Negocios Internacionales y responde a un enfoque moderno de la administración estratégica, así como a una visión global del mundo comercial de hoy. Un elemento clave que se busca desarrollar en el estudiante es la conciencia y visión comercial internacional de los negocios a partir de la globalización y el desarrollo de las tecnologías de la información que se viene dando en el mundo. Propósito: El curso tiene como propósito asegurar un sólido fundamento teórico - práctico del amplio panorama de los negocios internacionales, los cuales se realizan bajo diferentes modalidades. Así mismo, brinda al estudiante la oportunidad de familiarizarse con las principales fuerzas internas que enfrenta una empresa en su entorno nacional para poder hacer frente a todas aquellas fuerzas externas que le resultan incontrolables pero que debe entenderlas y buscar formas de enfrentarlas cuando se quiere ingresar a mercados externos. El curso desarrolla las competencias generales Pensamiento Innovador y Comunicación Oral, en el nivel de logro 1 y la competencia específica Evaluación de Oportunidades Internacionales en el nivel de logro 1. El curso no tiene pre requisitos

A global metagenomic map of urban microbiomes and antimicrobial resistance

We present a global atlas of 4,728 metagenomic samples from mass-transit systems in 60 cities over 3 years, representing the first systematic, worldwide catalog of the urban microbial ecosystem. This atlas provides an annotated, geospatial profile of microbial strains, functional characteristics, antimicrobial resistance (AMR) markers, and genetic elements, including 10,928 viruses, 1,302 bacteria, 2 archaea, and 838,532 CRISPR arrays not found in reference databases. We identified 4,246 known species of urban microorganisms and a consistent set of 31 species found in 97% of samples that were distinct from human commensal organisms. Profiles of AMR genes varied widely in type and density across cities. Cities showed distinct microbial taxonomic signatures that were driven by climate and geographic differences. These results constitute a high-resolution global metagenomic atlas that enables discovery of organisms and genes, highlights potential public health and forensic applications, and provides a culture-independent view of AMR burden in cities.Funding: the Tri-I Program in Computational Biology and Medicine (CBM) funded by NIH grant 1T32GM083937; GitHub; Philip Blood and the Extreme Science and Engineering Discovery Environment (XSEDE), supported by NSF grant number ACI-1548562 and NSF award number ACI-1445606; NASA (NNX14AH50G, NNX17AB26G), the NIH (R01AI151059, R25EB020393, R21AI129851, R35GM138152, U01DA053941); STARR Foundation (I13- 0052); LLS (MCL7001-18, LLS 9238-16, LLS-MCL7001-18); the NSF (1840275); the Bill and Melinda Gates Foundation (OPP1151054); the Alfred P.
