    Abstract: ... por la Comisión Nacional Forestal y el municipio de Taxco en los bienes comunales de San Pedro y San Felipe ...

    Abstract La investigación analiza los resultados obtenidos en un estudio de percepción social sobre el impacto socioeconómico del Pago por Servicios Ambientales Hidrológicos de Fondos Concurrentes implementado por la Comisión Nacional Forestal y el municipio de Taxco en los bienes comunales de San Pedro y San Felipe Chichila durante el periodo 2009-2012. A partir de una encuesta estadísticamente representativa, se muestra que desde la perspectiva del núcleo agrario el pago influye muy poco en la mejora de sus ingresos; sin embargo, ha propiciado un cambio en la valoración que tienen sobre el uso del bosque para un manejo más sustentable. La tradición organizativa y política de la comunidad es clave para entender la adopción de diferentes instrumentos favorables para la conservación de sus recursos forestales.

    Abstract Oocyte activation via dual inhibition of protein synthesis and phosphorylation has improved in vitro embryo production in different mammalian species. In this study, we evaluated the effects of the combination of cycloheximide (CHX), dimethyl amino purine (DMAP), and anisomycin (ANY) on the activation of bovine oocytes, particularly on dynamics of MPF and MAPKs, embryonic developmental potential, and quality. The results showed that the cleavage and blastocyst rates, as well as levels of CCNB1, CDK1, p-CDK1

    Abstract Helicobacter pylori is a Gram-negative bacterium that causes chronic gastric inflammation, which can lead to gastric neoplasia. Therefore, early diagnosis of H. pylori infection is crucial for effective treatment and prevention of complications. The aim of this study was to compare the sensitivity and specificity of the STANDARD™ F H. pylori Ag FIA stool antigen test (SD Biosensor) with the LIAISON® Meridian H. pylori SA for the diagnosis of H. pylori infection. A total of 133 stool samples from patients with suspected H. pylori infection were compared using the STANDARD™ F H. pylori Ag FIA stool antigen test (SD Biosensor), based on lateral flow assay, with the LIAISON® Meridian H. pylori SA. Of the 45 positive samples with LIAISON, 44 were also positive while 1 was negative in the STANDARD™ antigen test. However, this discrepant sample showed a chemiluminescence index of 1.18, very close to the cut-off point of 1. On the other hand, of 88 negative samples obtained with LIAISON, 83 were negative and 5 were positive in the STANDARD™ antigen test. Moreover, STANDARD™ F H. pylori Ag FIA assay has shown a sensitivity of 97.8% (95% CI: 88.2-99.9), a specificity of 94.3% (95% CI: 87.2-98.1), a PPV of 83.9% (95% CI: 68.9-92.4) and a NPV of 99.3% ((95% CI: 95.3-99.9). In conclusion, the STANDARD™ F H. pylori Ag FIA (SD Biosensor) on the STANDARD™ F2400 analyser is a highly sensitive, specific and suitable assay for the detection of H. pylori in stool samples.

    Abstract Oocyte activation via dual inhibition of protein synthesis and phosphorylation has improved in vitro embryo production in different mammalian species. In this study, we evaluated the effects of the combination of cycloheximide (CHX), dimethyl amino purine (DMAP), and anisomycin (ANY) on the activation of bovine oocytes, particularly on dynamics of MPF and MAPKs, embryonic developmental potential, and quality. The results showed that the cleavage and blastocyst rates, as well as levels of CCNB1, CDK1, p-CDK1 Thr161 , and p-CDK1 Thr14-Tyr15 , were similar among groups; ANY and ANY + CHX reduced the expression of ERK1/2 compared to DMAP-combinations ( p < 0.05), whereas ANY + DMAP, CHX + DMAP, and ANY + CHX + DMAP reduced p-ERK1/2 compared to ANY and ANY + CHX treatments ( p < 0.05). The quality of blastocysts in terms of cell counts, their allocation, and the numbers of TUNEL-positive cells did not differ among groups. However, transcript levels of POU5F1 were higher in embryos derived from ANY + CHX + DMAP treatment compared to other groups, while expression levels of CDX2 did not show differences. In addition, the BCL2A1/BAX ratio of the ANY + CHX + DMAP treatment was significantly low compared to the ANY treatment ( p < 0.05) and did not differ significantly from the other treatments. In conclusion, oocyte activation by dual inhibition of protein synthesis and phosphorylation induces MPF inactivation without degradation of CCNB1, while MAPK inactivation occurs differentially between these inhibitors. Thus, although the combined use of these inhibitors does not affect early developmental competence in vitro, it positively impacts the expression of transcripts associated with embryonic quality.
