A technique was developed to measure water exchange in the endometrical canal (uterine cavity). This type of determination should provide information necessary to understanding intrauterine pharmacokinetics. In the study described, measurements were performed on one cynomologus and four rhesus monkeys. Endometrial fluid in the uterine cavity was replaced with a 3H2O solution of known specific radioactivity (dpm/ml). Radioactivity remaining in the cavity at measured intervals of approximately 0.5, 1, 2, and 3 min following replacement was determined by flushing out the cavity. By extrapolating the 3H2O disappearance curve versus time to t = 0 (zero time), the apparent cavity volume (aVc) was derived. Values for aVc and t 1/2 3H2O were used to calculate endometrial fluid-water turnover rate. Mean values determined in four rhesus monkeys were as follows: aVc, 0.032 ml; t 1/2 H2O, 1.17 min; 24-h H2O turnover, 19.5 ml. In general, this value for H2O turnover was considerably higher than values of endometrial fluid production quantitated by other techniques. Water measurements in human uteri similar to those reported here appear feasible and are anticipated in future work.
The role of parenting in the development of children’s learning constitutes, at present, part of the discussion in the psychoeducational field. Although parental competences (pc) and executive functions (ef) have been investigated by psychology and neuropsychology, their relationship with academic competences remains to be fully studied. The aim of this investigation was to analyze the effect of pc perceived by parents on behavioral ef and performance-based measures of reading and mathematical competences in children. We worked with 131 school children of both sexes, between 9 and 11 years old, and their respective parents. Multivariate Analysis of Variance (manova) and structural equation model (sem) were used. The results indicate that parental skills from the parents’ perspective have a significant effect on ef, reading, and mathematical skills. However, the best fit model indicates that efs mediate the relationship between parenting skills and reading and math skills.
El objetivo de este trabajo es aportar un material teórico que acompañe los procesos de enseñanza de la técnica La pareja educativa, dentro del proceso diagnóstico psicopedagógico. Se procura sistematizar aportes respecto al test de la pareja educativa y proponer un dispositivo de análisis que nos permita inferir rasgos de la modalidad de aprendizaje del sujeto. Para ello, organizamos la presentación en tres apartados. El primero trata del origen y la creación del test. El segundo apartado es una revisión del uso de esta técnica en trabajos de investigación y su versión como técnica proyectiva psicopedagógica. Finalmente, se hace foco en la pareja educativa como técnica psicopedagógica incluida en el diagnóstico psicopedagógico. Se revisan los conceptos de asimilación y acomodación, modalidad de aprendizaje y, en último lugar, se propone un modo de analizar los indicios recogidos por la técnica que permita valorar el vínculo educativo e inferir rasgos de la modalidad de aprendizaje.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
