RESUMO
Five eyes of four patients were studied to analyze the structure of the inner wall of optic and chorioretinal colobomas using swept-source optical coherence tomography (SS-OCT). The colobomatous cavities and their relationship with adjacent structures were examined. SS-OCT permitted the study of the colobomatous cavities in all cases. In four of those cases, a Y-shaped intercalary membrane (ICM) was identified, with an origin in the retinal nerve fiber layer (RNFL), which covered the coloboma and in one case the coloboma was in contact with the vitreous cavity. Vitreous adhesion to the internal wall of the coloboma was found in three cases. No clinical or tomographic maculopathy was observed in any patient. High-resolution deep penetration SS-OCT allows in vivo study of optic and chorioretinal colobomas, identifying the RNFL as the main component of the ICM overlying the colobomatous cavities.
RESUMO
The aim of this study was to evaluate the survival of a probiotic microorganism microencapsulated in cellulose acetate phthalate, added to acerola nectar. The changes in pH, Brix, organic acid content and color of the product during its shelf-life were evaluated. A total of 3 processing runs were carried out on a semi-industrial scale, each consisting of a 15-liter batch of acerola nectar with added prebiotics and a microencapsulated probiotic culture. The physicochemical characteristics of the samples remained stable throughout storage. After 30 days storage the acerola nectar samples containing microencapsulated probiotic microorganisms exhibited counts above 8 log CFU per 200 mL, within the limits set by the Brazilian regulation for functional foods. On the other hand, the samples containing...(AU)

La influenza es una enfermedad aguda viral en las vías respiratorias altas capaz de provocar complicaciones potencialmente letales en pacientes ancianos. La vacunación anual es la intervención de salud más importante para reducir el impacto de la influenza. Existen diversos factores que influyen para la aceptación o rechazo de la aplicación de la vacuna. EI propósito de este estudio fue determinar las características de la población que acepta la vacuna de la influenza e identificar grupos de población que presentan riesgo, especialmente de no vacunarse en la comunidad de San Luis Tlaxialtemalco. EI estudio fue descriptivo y transversal. Con una muestra no probabilística y conformada por 48 personas de 60 y más años de edad. Se aplicó una encuesta estructurada de 25 preguntas y diferentes escalas. En cuanto a los resultados, el 84.48% aceptó la aplicación de la vacuna de la influenza. EI 81 .3% desconoce la enfermedad de la influenza, el 77.1 % cree que la influenza es grave, el 64.6% desconocía la vacuna contra la influenza, el 97.9% cree que previene la influenza y el 85.4% cree que la vacuna no le ocasionara problemas. Los factores que influyeron para la aceptación de la vacuna y en cuanto a quien se la recomendó el 31.3% refieren que fue la Enfermera y al 43.8% nadie.
Influenza is a high respitatory tract viral accute disease able to bring about potentially fatal complications in elderly patients. Theannual vaccination is the most important health intervention for decreasing the flu impact. There are several factors influencing the vaccine aplication acceptance or rejection. This study aims determining characteristics of the population that accepts the influenza vaccine and identifying in-risk population groups in the event they don´t receive it within San Luis Tlaxialtemalco area. It was a descriptive transversal study witha no-probalistic sample including 48 people, 60or more years old. A strctured survey with 25 questions and different scales. Regarding outcomes, 84.48% accepted the influenza vaccine application. The 81.3% are not familiar with influenza disease, 77.1% believes the flu is grave, 64.6% is not familiar with the influenza vaccine, 97.9% believes they are taking preventive actions for the influenza, and 85.4% thinks the influenza caccine will not cause them any problems, which is influencing on the vaccine acceptance. Regarding the person who recommended them the influenza vaccine, 31.3% said was the nurse and 43.8% said nobody did.

A study was conducted on calcium chloride treatment of canned okra acidified by adding either acetic, lactic, malic or tartaric acids or by lactic fermentation. The quality of the processed okra was determined by physical, chemical, microbiological and sensory analyses after a two month storage period at room temperature. The results indicated the possibility of processing high quality okra by small canneries, with low cost equipment and low energy requirements. The acidification procedures ensure minimal risk of botulism

La benzoilmercaptoacetiltriglicina (MAG,) se sintetizó de acuerdo con el método de A.R.Fritzberg y colaboradores. Se comprobó su pureza por punto de fusión, composición centesimal, cromatografía líquida de alta presión y resonancia magnética nuclear. Se realizaron estudios farmacológicos, esterilidad, apirogenicidad, toxicidad aguda y distribución biológica en animales. El producto (MAG,) marcado con tecnecio 99m, según la técnica de J.R.Coveney y M.S.Roblins, se controló por cromatografía en papel. Posteriormente, se inyectó en seres humanos (2,5-3 ,Ci) en normales y con patología renal (39 casos totales) realizándose el estudio comparativo con hipurán
