    Mild cognitive impairment (MCI) (amnestic or non-amnestic) has different clinical and neuropsychological characteristics, and its evolution is heterogeneous. Cardiovascular risk factors (CVRF), such as hypertension, diabetes, or dyslipidemia, and the presence of the Apolipoprotein E epsilon4 (ApoE epsilon4) polymorphism have been associated with an increased risk of developing Alzheimer's disease (AD) and other dementias but the relationship is inconsistent worldwide. We aimed to establish the association between the ApoE epsilon4 carrier status and CVRF on MCI subtypes (amnestic and non-amnestic) in Mexican older adults. Cross-sectional study including 137 older adults (n = 63 with normal cognition (NC), n = 24 with amnesic, and n = 50 with non-amnesic MCI). Multinomial logistic regression models were performed in order to determine the association between ApoE epsilon4 polymorphism carrier and CVRF on amnestic and non-amnestic-MCI. ApoE epsilon4 carrier status was present in 28.8% participants. The models showed that ApoE epsilon4 carrier status was not associated neither aMCI nor naMCI condition. The interaction term ApoE epsilon4 x CVRF was not statistically significant for both types of MCI. However, CVRF were associated with both types of MCI and the association remained statistically significant after adjustment by sex, age, and education level. The carrier status of the ApoE genotype does not contribute to this risk

    Se evaluó el efecto de recubrimientos comestibles (RC) de quitosano (Q) (1 y 2 %) con o sin la adición de aceite esencial de canela (AC) (0,03, 0,07 y 0,1 %) sobre los cambios en aceptabilidad, fenoles totales, capacidad antioxidante y población microbiana en fresas. Fresas sin recubrimiento se utilizaron como control. Frutos tratados fueron almacenados por 15 días a 5°C y se evaluaron cambios en la calidad a intervalos de 3 días. Fresas tratadas y control no mostraron diferencias en el contenido de fenoles totales y capacidad antioxidante. Todos los tratamientos redujeron significativamente la población microbiana con respecto al control. RC con Q 2 % + AC 0,1 % redujo en mayor magnitud el crecimiento microbiano (2 Log ufc/g) sin afectar la calidad después de 14 días a 5°C, seguido del RC de Q 1 % + AC 0,1 % con 1,5 Log ufc/g de reducción y vida de anaquel de 15 días. El control presentó 8 días de vida de anaquel; todos los recubrimientos presentaron la mayor aceptabilidad en comparación con el control. Estos resultados indican que los RC de quitosano con aceite de canela pueden prolongar la vida de anaquel de fresas por 15 días a 5ºC

    BACKGROUND: The Edinburgh Postnatal Depression Scale (EPDS) is a widely used instrument to measure postnatal depression. This study aimed to translate and to test the reliability and validity of the EPDS in Iran. METHODS: The English language version of the EPDS was translated into Persian (Iranian language) and was used in this study. The questionnaire was administered to a consecutive sample of 100 women with normal (n = 50) and caesarean section (n = 50) deliveries at two points in time: 6 to 8 weeks and 12 to 14 weeks after delivery. Statistical analysis was performed to test the reliability and validity of the EPDS. RESULTS: Overall 22% of women at time 1 and 18% at time 2 reported experiencing postpartum depression. In general, the Iranian version of the EPDS was found to be acceptable to almost all women. Cronbach's alpha coefficient (to test reliability) was found to be 0.77 at time 1 and 0.86 at time 2. In addition, test-rest reliability was performed and the intraclass correlation coefficient was found to be 0.80. Validity as performed using known groups comparison showed satisfactory results. The questionnaire discriminated well between sub-groups of women differing in mode of delivery in the expected direction. The factor analysis indicated a three-factor structure that jointly accounted for 58% of the variance. CONCLUSION: This preliminary validation study of the Iranian version of the EPDS proved that it is an acceptable, reliable and valid measure of postnatal depression. It seems that the EPDS not only measures postpartum depression but also may be measuring something more

    Medición de captura y almacenamiento de carbono. Proyecto Charco Bendito. Modelo estratégico de restauración de microcuenca Cajititlán

    El siguiente proyecto se realizó a partir del trabajo colaborativo realizado en el PAP Laboratorio de análisis de datos geoespaciales, el cual se centró en la identificación y análisis del carbono en el área de trabajo del proyecto “Charco Bendito” desarrollado por Red Bioterra SC. Se midieron los niveles de secuestro de carbono en el suelo del área trabajada por el equipo de Charco Bendito, esto con el propósito de conocer el secuestro antes del inicio del proyecto, tras haber limpiado la jarilla y plantar árboles endémicos. Además, se realizó una predicción a través de los datos adquiridos de cuál será el secuestro de carbono futuro del proyecto para el año 2028, y se analizará la cantidad de dólares ganados por la captura de carbono. Los objetivos anteriores se llevaron a cabo analizando las imágenes de satélite Sentinel-2 (teledetección) utilizando el software de código abierto QGIS. A partir de este trabajo, se realiza el modelado matemático del precio del carbono capturado, utilizando la herramienta de software libre InVEST, haciendo uso de sus tres modelos matemáticos y seleccionando aquel que otorgó mejores resultados. El motivo por el que se realiza el proyecto cuenta con aspectos tanto sociales como económicos. En el aspecto económico, se cuenta con las ganancias adquiridas de los bonos de carbono. El aspecto social, por su parte, en la mitigación del cambio climático a través de la restauración de los bosques. La dificultad se encuentra en la medición del carbono almacenado tanto en los bosques como suelos y demás flora con la que se cuenta. Para facilitar este procedimiento, se utilizarán las imágenes de satélite y algoritmos de análisis determinando la cantidad de carbono almacenado por pixel en las imágenes proporcionando un resultado más preciso a corto plazo y con mínimo costo. Se aplicó la metodología geoespacial recomendada para establecer el sistema de monitoreo, reporte y verificación por el (INECC-SEMARNAT, 2018) en el que la aportación de las ciencias geoespaciales contribuye con la representación espacial de los cambios en todos los periodos se hace en los mapas de cambio obtenidos a través de la sobreposición de mapas de vegetación. Cada uno alimenta una matriz de transición y con ellos se obtienen los datos de actividad para cada transición, en esencia así es como funciona el modelo InVEST. Los propósitos de este proyecto se enfocan en generar la información de interés para Red Bioterra con respecto al secuestro de carbono en su área de trabajo. Además de analizar las ganancias a adquirir de los bonos de carbono identificados, monetizados con el uso de datos de sistemas de comercio de emisiones.ITESO, A.C

    A proteomics approach to decipher the molecular nature of planarian stem cells

    Background In recent years, planaria have emerged as an important model system for research into stem cells and regeneration. Attention is focused on their unique stem cells, the neoblasts, which can differentiate into any cell type present in the adult organism. Sequencing of the Schmidtea mediterranea genome and some expressed sequence tag projects have generated extensive data on the genetic profile of these cells. However, little information is available on their protein dynamics. Results We developed a proteomic strategy to identify neoblast-specific proteins. Here we describe the method and discuss the results in comparison to the genomic high-throughput analyses carried out in planaria and to proteomic studies using other stem cell systems. We also show functional data for some of the candidate genes selected in our proteomic approach. Conclusions We have developed an accurate and reliable mass-spectra-based proteomics approach to complement previous genomic studies and to further achieve a more accurate understanding and description of the molecular and cellular processes related to the neoblasts

    Comparison of major depression diagnostic classification probability using the SCID, CIDI, and MINI diagnostic interviews among women in pregnancy or postpartum: An individual participant data meta-analysis

    Get PDF
    Objectives A previous individual participant data meta-analysis (IPDMA) identified differences in major depression classification rates between different diagnostic interviews, controlling for depressive symptoms on the basis of the Patient Health Questionnaire-9. We aimed to determine whether similar results would be seen in a different population, using studies that administered the Edinburgh Postnatal Depression Scale (EPDS) in pregnancy or postpartum. Methods Data accrued for an EPDS diagnostic accuracy IPDMA were analysed. Binomial generalised linear mixed models were fit to compare depression classification odds for the Mini International Neuropsychiatric Interview (MINI), Composite International Diagnostic Interview (CIDI), and Structured Clinical Interview for DSM (SCID), controlling for EPDS scores and participant characteristics. Results Among fully structured interviews, the MINI (15 studies, 2,532 participants, 342 major depression cases) classified depression more often than the CIDI (3 studies, 2,948 participants, 194 major depression cases; adjusted odds ratio [aOR] = 3.72, 95% confidence interval [CI] [1.21, 11.43]). Compared with the semistructured SCID (28 studies, 7,403 participants, 1,027 major depression cases), odds with the CIDI (interaction aOR = 0.88, 95% CI [0.85, 0.92]) and MINI (interaction aOR = 0.95, 95% CI [0.92, 0.99]) increased less as EPDS scores increased. Conclusion Different interviews may not classify major depression equivalently
