De novo transcriptomic analyses revealed some detoxification genes and related pathways responsive to noposion yihaogong® 5% EC (Lambda-Cyhalothrin 5%) exposure in spodoptera frugiperda third-instar larvae

The fall armyworm, Spodoptera frugiperda (J.E. Smith) (Lepidoptera: Noctuidae), is a polyphagous, invasive insect pest which causes significant losses in important crops wherever it has spread. The use of pesticides in agriculture is a key tool in the management of many important crop pests, including S. frugiperda, but continued use of insecticides has selected for various types of resistance, including enzyme systems that provide enhanced mechanisms of detoxification. In the present study, we analyzed the de novo transcriptome of S. frugiperda larvae exposed to Noposion Yihaogong® 5% emulsifiable concentrate (EC) insecticide focusing on detoxification genes and related pathways. Results showed that a total of 1819 differentially expressed genes (DEGs) were identified in larvae after being treated with Noposion Yihaogong® 5% EC insecticide, of which 863 were up- and 956 down-regulated. Majority of these differentially expressed genes were identified in numerous Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways, including metabolism of xenobiotics and drug metabolism. Furthermore, many of S. frugiperda genes involved in detoxification pathways influenced by lambda-cyhalothrin stress support their predicted role by further co-expression network analysis. Our RT-qPCR results were consistent with the DEG’s data of transcriptome analysis. The comprehensive transcriptome sequence resource attained through this study enriches the genomic platform of S. frugiperda, and the identified DEGs may enable greater molecular underpinnings behind the insecticide-resistance mechanism caused by lambda-cyhalothrin

Explorando la adopción de ERP con el modelo Business Process Change (BPC): Tres casos de estudio en Chile

Si bien existen numerosos estudios enfocados en determinar factores críticos de éxito en la adopción de ERP, mayoritariamente no se basan en teoría y se realizan en países desarrollados. Basada en el modelo Business Process Change (BPC), el objetivo de este trabajo es explorar el proceso de implementación de ERP de tres importantes empresas Chilenas, con el fin de identificar los factores que favorecen o inhiben una implementación exitosa. Los resultados obtenidos confirman muchos de los factores críticos de éxito encontrados en la literatura y ratifican la importancia del modelo BPC como base en el estudio de este fenómeno

Demystifying the growth of superconducting Sr2RuO4 thin films

We report the growth of superconducting Sr2RuO4 thin films by molecular-beam epitaxy on (110) NdGaO3 substrates with transition temperatures of up to 1.8 K. We calculate and experimentally validate a thermodynamic growth window for the adsorption-controlled growth of superconducting Sr2RuO4 epitaxial thin films. The growth window for achieving superconducting Sr2RuO4 thin films is narrow in growth temperature, oxidant pressure, and ruthenium-to-strontium flux ratio
