ABSTRACT Supplementation with bioproducts (BP) can be an efficient alternative for the crop management, especially in those that are managed with low applications of mineral fertilizers. The objective of this study was to evaluate the complementary application of the bioproducts ME-50 and FitoMas-E (FE) in the increase of the common bean productivity. An experiment was carried out under field conditions with the common bean cultivar Bat-304. Treatments were distributed in a randomized block design, in a factorial scheme (2 × 2). Two levels of mineral fertilization (0 and 50 kg ha-1) and the application of the bioproducts ME-50 (100 mL L-1) and FE (2 L ha-1), with five repetitions were studied. At 40 days after the emergence, the average of trifoliate leaves per plant was determined and in the harvest the number of pods per plant, grains per plant, grains per pod, mass of 100 grains (g) and yield (kg ha-1) were evaluated. The results showed that application of the ME-50 and FE bioproducts increased the morphophysiological and productive parameters of the bean, with the consequent increase in yield in the presence of mineral fertilization. The results indicated that the ME-50 bioproduct was superior to the FE in both culture conditions. This study suggests that the use of both bioproducts constitutes an important contribution to the productive management of the species which improved the productive component and consequently the yield.

RESUMEN La suplementación con bioproductos (BP) puede constituir una alternativa eficiente para el manejo de los cultivos, sobre todo en aquellos que se utilicen bajas aplicaciones de fertilizantes minerales. El objetivo de este estudio fue evaluar la aplicación complementaria de los bioproductos ME-50® y FitoMas-E® (FE) en el aumento de la productividad del frijol común. Se realizó un experimento en condiciones de campo con el cultivar ʻBat-304ʼ de frijol común. Los tratamientos se distribuyeron en un diseño en bloques al azar, en esquema factorial 2×2. Fueron estudiados dos niveles de fertilización mineral (0 y 50 kg ha-1) y la aplicación de los bioproductos ME-50 (100 mL L-1) y FE (2 L ha-1), con cinco repeticiones. A los 40 días después de la emergencia fue determinado el promedio de hojas trifoliadas por planta y en la cosecha fueron evaluados el número de vainas por planta, granos por planta, granos por vaina, la masa de 100 granos y el rendimiento. Los resultados mostraron que la aplicación de los bioproductos ME-50 y FitoMas-E incrementaronlos parámetros morfofisiológicos y productivos del frijol, con el consecuente incremento del rendimiento en presencia de la fertilización mineral. Los resultados indicaron que el bioproducto ME-50 fue superior al FitoMas-E en ambas condiciones de cultivo. Este estudio sugiere que la utilización de ambos bioproductos constituye una contribución importante al manejo productivo de la especie porque mejora los componentes productivos y consecuentemente el rendimiento.

Abstract Laron’s syndrome (LS) is a rare genetic disorder characterized by insensitivity to growth hormone (GH). Up to the present time, over 70 mutations of GH receptor (GHR) gene have been identified leading to GH/insulin-like growth factor type 1 (IGF1) signaling pathway defect. The number of LS patients worldwide is unknown, as many are probably undiagnosed. We report two sibs from a consanguineous family from Minas Gerais, southeastern Brazil. The parents have three children. The older, a 4-years-old girl was 80.2 cm tall (-5.7 SDS height/age), and the youngest sister, aged 3 years, was 73.2 cm tall (-5.82 SDS height/age). Their clinical and biochemical features are typical of LS patients, such as high serum level of GH and low IGF1 concentrations. A homozygous c.1A>T nucleotide substitution in GHR exon 2 in the probands’ samples was identified. Their parents and healthy sister are heterozygous for the same variant that abolishes the translation initiation codon of GHR. This mutation has not been reported in Brazilian patients and was previously associated with an LS phenotype in a single 29-year-old Spanish man. In addition to this case report, we summarize the main characteristics and molecular data of the 21 LS Brazilian patients who have been published to date.

Se determinó la variación espacio temporal de las plantas vasculares acuáticas en las ciénagas de María Arriba, San Sebastián, Purísima y Momil del complejo cenagoso del bajo Sinú (CCBS), en el departamento de Córdoba (Colombia), abarcando los periodos hidrológicos ocurridos durante el año 2011. El área de estudio se dividió en cuatro sectores y mediante el método de intercepción en línea se determinó la abundancia y frecuencia de las hidrófitas. Se registraron 39659 individuos distribuidos en 24 familias, 30 géneros y 35 especies. La mayor abundancia de especies se presentó en Momil con 18582 individuos, siendo la familia Lemnaceae la más representativa. El análisis de varianza (ANOVA) indica que no existen diferencias estadísticas significativas en la abundancia de la especies de plantas acuáticas de los meses de muestreo (F = 1,04; GL = 11; p = 0,083), sin embargo, se evidenció la incidencia del período hidrológico sobre la dinámica de crecimiento de las plantas, algunas especies desaparecen en época seca, otras sobreviven un periodo corto de tiempo, mientras que otras como Lemna minor L y Salvinia auriculata Aubl aumentan en época de lluvia.

The space-time variation of vascular aquatic vegetation was studied in Maria Arriba, San Sebastian, Purísima and Momil swamps of the lower Sinú swamp complex, located in the department of Córdoba (Colombia), covering hydrological periods occurred in one year. The area of study was divided in four sectors and by the linear intercept method it was determined the abundance and frequency of the hydrophytes. They were recorded 39659 individuals distributed in 24 families, 30 genus and 35 species. The highest abundance of species was presented in Momil with 18582 individuals being the family Lemnaceae the most representative. The analysis of variance (ANOVA) shows that not exist statistically significantly different in the abundance of the species of aquatic plants from sampling months (F = 1,04; GL = 11; p = 0,083), however, it has demonstrated the incidence of a hydrological period on the plants dynamic growth, some species disappear in dry season, others survive for a short period of time, while others like Lemna minor L. y Salvinia auriculata Aubl. increase in the rainy season.
