Abstract: Se determinó la osmolalidad de bebidas de consumo frecuente por los ni os y adolescentes debido a la escasa información existente en nuestro país. Las muestras se agruparon en leches, bebidas refrescantes, con base en frutas, hortalizas, cereales y tubérculos; deportivas, energéticas, soluciones de rehidratación oral, reconstituidas e infusiones. Se utilizó un osmómetro digital de presión de vapor, analizando cinco muestras de cada bebida, lotes diferentes. A cada muestra se le hicieron cuatro determinaciones de osmolalidad calculando el promedio de dichos valores. Cuando el coeficiente de variación de las medidas de osmolalidad de las cinco muestras fue superior a 10%, se analizaron 5 muestras adicionales. Con la leche materna se utilizaron las muestras que fueron posibles recolectar durante el estudio. Se calcularon promedios de osmolalidad, desviación estándar e intervalo de confianza de los valores de osmolalidad (95% confiabilidad). La osmolalidad (mmol/kg) de la leche materna y de vaca estuvieron entre 273 y 389; las bebidas refrescantes, colas blancas, negras, sabores y maltas oscilaron entre 479-811 y la soda y bebidas light: 44-62; bebidas de frutas naturales y comerciales (coco, durazno, manzana, naranja, pera, pi a, uva, ciruela, tamarindo): 257-1152 y los jugos light: 274; bebidas deportivas: 367; bebidas energéticas: 740; bebidas basadas en hortalizas y cereales: 213-516; soluciones de rehidratación oral: 236-397; bebidas reconstituidas: 145; infusiones: 25. Las bebidas con osmolalidad en rango adecuado para los ni os fueron: leches, refrescos light, soda, jugos naturales y light, bebidas de rehidratación oral, de soya, reconstituidas e infusiones.

Abstract: Se determinó la osmolalidad de fórmulas y productos para la terapia nutricional disponibles en Venezuela. Las muestras se agruparon en fórmulas infantiles de inicio, neonatos de bajo peso, infantiles de continuación, 1 a 4 a os, a base de soya, sin lactosa, antirreflujo, hipoalergénicas, dietas con nutrientes intactos basadas en leche (DNIBL), fórmulas poliméricas, semielementales, módulos calóricos y proteicos. Se utilizó un osmómetro digital de presión de vapor, analizando cinco muestras por producto, preparadas por medida y por peso, de lotes diferentes. Cuando el coeficiente de variación de las medidas de osmolalidad fue mayor a 10%, se analizaron 5 muestras adicionales. Se calcularon promedios, desviación estándar y coeficiente de variación de los valores de osmolalidad (95% confiabilidad). La osmolalidad (mmol/kg) de las fórmulas de inicio y de neonatos de bajo peso estuvieron entre 258 y 309; las de continuación: 256-390; de ni os de 1 a 4 a os: 343-399; a base de soya: 155-252; sin lactosa: 163-248; antirreflujo: 230-292; hipoalergénica: 220-335; DNIBL: 205-454; poliméricas: 247-588; semielementales: 238-289; módulo calórico: 89-99; y proteico: 30-60. Se encontró que generalmente las fórmulas preparadas con medidor tenían mayor osmolalidad y variabilidad que las preparadas según el peso. Algunas fórmulas de continuación, poliméricas, fórmulas para ni os de 1 a 4 a os y con nutrientes intactos basadas en leche tuvieron osmolalidades elevadas por lo que no deben ser administradas a lactantes, y con precaución a ni os y adolescentes cuando el tracto gastrointestinal esté comprometido.

Abstract: inolder to estimate the prevalence of vitamin a deficiency in children with malnutrition, plasma retinol concentration was measured by hplc, and the relative dose response test (rdr) was applied to 124 children of both sexes and under 10 years of age attended at the centro de atención nutricional infantil antímano. after a night of fasting, a blood sample was taken from each child. the medical evaluation emphasized the detection of clinical signs of vitamin a deficiency and recent respiratory and infections history or diarrhea. the adequacy of dietary vitamin a intake was determined by a 24 hour intake recall. the mean of plasma retinal concentration was 28.6 μg/dl; 10.4% had plasma retinol under 20 μg/dl; also, 10.6% of the sample showed rdr values higher than 20%. a higher prevalence was observed in children under 2 years of age (21.2%, p<0.05). in these children, ocular clinical signs of vitamin a deficiency code absent there was a significant relation between a pneumonia history and plasma retinol concentration, but there was no relation between diarrhea and plasma retinal concentration. the mean of vitamin a adequacy intake was 121.2%. these results pointed to the existence of subclinic vitamin a deficiency in the population studied. the severity of the deficiency was higher in children under 2 years of age and requires special attention. this problem did not require vitamin a supplementation, but should be resolved by the nutritional education of the population.

Abstract: The binding affinity of p53 for the MG promoter was assessed by DNA-affinity chromatography with the extended α2-macroglobulin (MG) gene promoter (-852/+12) and immunoblot analysis. During the increased MG gene transcription observed in the fetus and the acute-phase (AP) response in both the fetus and the adult, p53 exhibited increased binding to the MG promoter. This increase was accompanied by decreased O-linked N-acetyl glucosamine glycosylation of p53. We suggest that the enzymatic removal of sugar moieties in vivo serves to activate the MG gene promoter binding potential of p53 and its participation in upregulated MG gene transcription.
