Outcomes from elective colorectal cancer surgery during the SARS-CoV-2 pandemic

This study aimed to describe the change in surgical practice and the impact of SARS-CoV-2 on mortality after surgical resection of colorectal cancer during the initial phases of the SARS-CoV-2 pandemic

Evolutionary Selection of a Set of Association Rules Considering Biological Constraints Describing the Prevalent Elements in Bacterial Vaginosis

Bacterial Vaginosis is a common disease and recurring public health problem. Additionally, this infection can trigger other sexually transmitted diseases. In the medical field, not all possible combinations among the pathogens of a possible case of Bacterial Vaginosis are known to allow a diagnosis at the onset of the disease. It is important to contribute to this line of research, so this study uses a dataset with information from sexually active women between 18 and 50 years old, including 17 numerical attributes of microorganisms and bacteria with positive and negative results for BV. These values were semantically categorized for the Apriori algorithm to create the association rules, using support, confidence, and lift as statistical metrics to evaluate the quality of the rules, and incorporate those results in the objective function of the DE algorithm. To guide the evolutionary process we also incorporated the knowledge of a human expert represented as a set of biologically meaningful constraints. Thus, we were able to compare the performance of the rand/1/bin and best/1/bin versions from Differential Evolution to analyze the results of 30 independent executions. Therefore the experimental results allowed a reduced subset of biologically meaningful association rules by their executions, dimension, and DE version to be selected

Data from: Connecting genomic patterns of local adaptation and niche suitability in teosintes

The central-abundance hypothesis predicts that local adaptation is a function of the distance to the center of a species’ geographic range. To test this hypothesis, we gathered genomic diversity data from 49 populations, 646 individuals and 33,464 SNPs of two wild relatives of maize, the teosintes Zea mays ssp. parviglumis and Zea. mays. ssp. mexicana. We examined the association between the distance to their climatic and geographic centroids and the enrichment of SNPs bearing signals of adaptation. We identified candidate adaptive SNPs in each population by combining neutrality tests and cline analyzes. By applying linear regression models, we found that the number of candidate SNPs is positively associated with niche suitability, while genetic diversity is reduced at the limits of the geographic distribution. Our results suggest that overall, populations located at the limit of the species’ niches are adapting locally. We argue that local adaptation to this limit could initiate ecological speciation processes and facilitate adaptation to global change

SNPdata_Aguirre_Liguori_etal_SNPdata

The SNPdata_Aguirre_Liguori_etal.txt file contains the genotypes exported from GenomeStudio. SNPs were genotyped using the Illumina MaizeSNP50 Genotyping BeadChip. Loci are in rows and individuals are in columns. Each column is named as the population and individual separated by “_”. For example “Mochitlan_Mochitlan_9” indicates that the individual comes from the site Mochitlan in the Mochitlan “Municipio” and corresponds to the 9th individual. Sample information (Population, coordinates and the subspecies) is found in the sample_information_Aguirre_Liguori_etal.txt file and in the manuscript. Genotypes downloaded from Pyhäjärvi et al. (2013) can be found in the following link http://datadryad.org/resource/doi:10.5061/dryad.8m648/

Memoria del tercer simposium sobre Historia, sociedad y cultura de México y América Latina

Esta Memoria del Tercer Simposium sobre Historia, Sociedad y Cultura de México y América Latina no sólo reúne 38 trabajos presentados durante el evento celebrado del 9 al 11 de octubre de 2007, sino que es constancia del interés de los investigadores y de las instituciones participantes por abordar temas que preocupan a la sociedad latinoamericana actual.El objetivo principal de este trabajo es doble. En el primer apartado, “Democracia y autoritarismo”, se establecen y comentan sendas definiciones de democracia y autoritarismo que, en principio, se podrían aplicar a cualquier sistema político de la historia de la humanidad. En el segundo apartado, “Aspectos por considerar en estudios de caso sobre cualquier tipo de democracia”, se mencionan algunos tópicos concretos involucrados en la concepción de democracia expuesta en el apartado anterior, con la finalidad de proporcionar elementos de análisis a quienes deseen aplicarlos a estudios de caso
