Complete replacement of corn by white or red sorghum in japanese quail feeds

This study aimed at evaluating the total replacement of corn by white or red sorghum and the inclusion or not of pigment in the diet on the performance and yolk color of Japanese quail eggs. In the trial, 210 Japanese quails were distributed according to a completely randomized experimental design consisting of five treatments with six replicates of seven birds each. Treatments consisted of Corn-based diet (C), white sorghum-based diet (WS), white sorghum-based diet + pigment (WSP), red sorghum-based diet (RS), and red sorghum-based diet + pigment (RSP). Feed intake, feed conversion ratio, egg production, and egg mass were no influenced by the treatments. However, paler egg yolks were produced when corn was replaced by sorghum. When red and white sorghum varieties were compared, there were no differences in yolk color or response to pigment dietary inclusion. It was concluded that the total replacement of corn by sorghum in the feed did not influence the performance of Japanese quails and that yolk color response is not affected by the inclusion of pigments in diets containing sorghum, independently of its variety.

Marcadores séricos en preeclampsia / Serum markers in pre-eclampsia

INTRODUCCIÓN La preeclampsia es una patología del embarazo, etiología desconocida con morbimortalidad materno-perinatal. OBJETIVOS Evaluar los marcadores moleculares Activina A, PAPP-A, PP13 e Inhibina A. Detectar precozmente cuáles son las mujeres con alto riesgo de desarrollar preeclampsia, generar un banco de muestras de sangre, determinar los marcadores en los tres trimestres y establecer si son predictivos y se relacionan con la enfermedad. MÉTODOS Se incorporó a mujeres con embarazo normal y no embarazadas. Se tomaron muestras de sangre entre las semanas 10-12 y 17-20 del embarazo y en el parto. Las muestras fueron alicuotadas y almacenadas a -80 ºC hasta su utilización. Se dosificaron los marcadores por técnica ELISA con kits comerciales. RESULTADOS La concentración de Activina A se incrementó en el primer trimestre en las pacientes con preeclampsia leve. Se observó una disminución en la concentración de PAPP-A en el primer trimestre en las pacientes con desarrollo de preeclampsia, una disminución de PP13 en el primer y el segundo trimestres en las pacientes con preeclampsia leve estadísticamente significativa en el primer trimestre (p=0,038) y una disminución de Inhibina A en el tercer trimestre en las pacientes con preeclampsia severa (p=0,014). DISCUSIÓN La determinación de PP13 en el primer trimestre del embarazo es útil para la predicción de preeclampsia leve. Los resultados hallados son discordantes con los de otros autores que también encuentran diferencias significativas en las concentraciones de los marcadores Activina A, PAPP-A e Inhibina A.
