Approach to Identify Internal Best Practices in a Software Organization.

Current approaches to software process improvements (SPI) in software organizations is based on identifying gaps by comparing the way organizations work with respect to practices contained in the reference models. Later, these gaps will be targeted for establishing software process improvements. This paper presents an approach for identifying best practices within the organization. This is considered a key element in order to compare the way software organizations work with the reference models. After that, these practices will be complemented with practices contained in these models depending on the organization's business goals

IL-10-conditioned dendritic cells, decommissioned for recruitment of adaptive immunity, elicit innate inflammatory gene products in response to danger signals

Dendritic cells (DCs) are the professional APCs of the immune system, enabling T cells to perceive and respond appropriately to potentially dangerous microbes, while also being able to maintain T cell tolerance toward self. In part, such tolerance can be determined by IL-10 released from certain types of regulatory T cells. IL-10 has previously been shown to render DCs unable to activate T cells and it has been assumed that this process represents a general block in maturation. Using serial analysis of gene expression, we show that IL-10 pretreatment of murine bone marrow-derived DCs alone causes significant changes in gene expression. Furthermore, these cells retain the ability to respond to Toll-like receptor agonists, but in a manner skewed toward the selective induction of mediators known to enhance local inflammation and innate immunity, among which we highlight a novel CXCR2 ligand, DC inflammatory protein-1. These data suggest that, while the presence of a protolerogenic and purportedly anti-inflammatory agent such as IL-10 precludes DCs from acquiring their potential as initiators of adaptive immunity, their ability to act as initiators of innate immunity in response to Toll-like receptor signaling is enhanced

Identificacion de las mejores practicas de una organización de desarrollo software mediante la gestión de su conocimiento

En este artículo se describe un método para la identificación de las mejores prácticas de una organización de desarrollo de software, enfocándose en la disminución de la resistencia al cambio, a través de la gestión de su conocimiento. La importancia de la identificación de las mejores prácticas de una organización radica en que esta actividad permite conocer cómo trabaja una organización mediante la formalización, conservación y promoción de su conocimiento clave, lo cual, permitirá que las iniciativas de mejora de los procesos de la organización sean llevadas a cabo con éxito

Previous studies have suggested concordant DNA hypermethylation between tumor pairs. However, only a few methylation markers have been analyzed. This study was aimed at describing the epigenetic signature of multiple CRC using a genome-scale DNA methylation profiling. We analyzed 12 patients with synchronous CRC and 29 age-, sex-, and tumor location-paired patients with solitary tumors from the EPICOLON II cohort. DNA methylation profiling was performed using the Illumina Infinium HM27 DNA methylation assay. The most significant results were validated by Methylight. Tumors samples were also analyzed for the CpG Island Methylator Phenotype (CIMP); KRAS and BRAF mutations and mismatch repair deficiency status. Functional annotation clustering was performed. We identified 102 CpG sites that showed significant DNA hypermethylation in multiple tumors with respect to the solitary counterparts (difference in β value ≥0.1). Methylight assays validated the results for 4 selected genes (p = 0.0002). Eight out of 12(66.6%) multiple tumors were classified as CIMP-high, as compared to 5 out of 29(17.2%) solitary tumors (p = 0.004). Interestingly, 76 out of the 102 (74.5%) hypermethylated CpG sites found in multiple tumors were also seen in CIMP-high tumors. Functional analysis of hypermethylated genes found in multiple tumors showed enrichment of genes involved in different tumorigenic functions. In conclusion, multiple CRC are associated with a distinct methylation phenotype, with a close association between tumor multiplicity and CIMP-high. Our results may be important to unravel the underlying mechanism of tumor multiplicity.This work was supported by grants from the Hospital Clínic of Barcelona (Josep Font grant), Ministerio de Economí­a y Competitividad (SAF 2007-64873 and SAF2010-19273), Fundación Científica de la Asociación Española contra el Cáncer, and Instituto de Salud Carlos III (PI10/00384). “Cofinanciado por el Fondo Europeo de Desarrollo Regional (FEDER).

CARGO: a web portal to integrate customized biological information

There is a huge quantity of information generated in Life Sciences, and it is dispersed in many databases and repositories. Despite the broad availability of the information, there is a great demand for methods that are able to look for, gather and display distributed data in a standardized and friendly way. CARGO (Cancer And Related Genes Online) is a configurable biological web portal designed as a tool to facilitate, integrate and visualize results from Internet resources, independently of their native format or access method. Through the use of small agents, called widgets, supported by a Rich Internet Application (RIA) paradigm based on AJAX, CARGO provides pieces of minimal, relevant and descriptive biological information. The tool is designed to be used by experimental biologists with no training in bioinformatics. In the current state, the system presents a list of human cancer genes.
