Latino children are diagnosed with autism spectrum disorder later in life, usually with more severe symptoms, and lower IQs, compared with non-Latino children. Possible reasons for such disparities could be due to lower levels of parent education, lower socioeconomic status, limited knowledge of parents about autism spectrum disorder, and diminished health-care knowledge. The goal of the study was to describe the age of parental concerns and at first autism spectrum disorder diagnosis, and factors associated with age at the first diagnosis in a sample of Venezuelan children. Diagnostic and demographic data were collected from 103 children between 2 and 7 years of age. Although the mean age of first concerns was 17 months, the age of diagnosis varied from 53.03 months for the Pervasive Developmental Disorders-Not Otherwise specified group to 54.38 months for the autism group. Although parents were aware of developmental difficulties before the second year of life, their children were diagnosed 36 months later. In Latin cultures, behavior problems are usually attributed to poor parenting skills, so parents might take longer to seek professional help. A better understanding of cultural influences on age of diagnosis will translate to quicker use of services independent of ethnicity.
El análisis de la planificación financiera en empresas cementeras del Estado Zulia-Venezuela, fundamenta el objetivo del presente artículo. Desde la perspectiva metodológica, se establece una investigación analítica descriptiva, diseño no experimental, transeccional, y cuyas bases teóricas se fundamentan en la planificación financiera, la investigación se tipifica como descriptiva, método cualitativo. La selección de la técnica permitió el desarrollo de un cuestionario estructurado cuyos resultados determinan que según aplicación de la planificación financiera, se determinan los elementos que intervienen en la planificación fundamentada en la perspectiva organizacional lo cual incide en la elaboración de presupuestos y a su vez son determinantes en las decisiones de financiamiento, las herramientas de control financiero lo que permite la comparación de índices financieros y análisis de las desviaciones.
The mechanisms of cholinergic activation of carbohydrate metabolism were investigated in isolated rabbit gastric glands. Carbachol stimulated the rate of glucose oxidation in a dose-dependent fashion with a half-maximal effect occurring at approximately 9 microM. Atropine and omeprazole, but not cimetidine, completely blocked the stimulation induced by carbachol. Direct activation of the H(+)-K(+)-adenosinetriphosphatase by NH+4 caused a significant stimulation of glucose oxidation that was totally abolished by oligomycin and by the mitochondrial uncouplers dinitrophenol and carbonyl cyanide p-trifluoromethoxyphenylhydrazone. These latter agents did not abolish the stimulating effect of carbachol on glucose oxidation. Ionomycin increased the rate of glucose oxidation in a dose-dependent manner, and this effect was not blocked by oligomycin. The metabolic effect of ionomycin was reduced but not abolished by omeprazole. 1,2-Bis(2-aminophenoxy)ethane-N,N,N',N'-tetraacetic acid acetoxymethyl ester eliminated the carbachol-induced stimulation of glucose oxidation and partially inhibited the effect of NH+4. The mitochondrial enzymes pyruvate dehydrogenase and oxoglutarate dehydrogenase were activated by physiological concentrations of calcium in the isolated mitochondria. This effect was blocked by incubation with ruthenium red.(ABSTRACT TRUNCATED AT 250 WORDS)
