Genetic variability among cassava accessions based on SSR markers
Ribeiro, Márcia de Nazaré Oliveira;Carvalho, Samuel Pereira de;Santos, Jo?o Bosco dos;Antonio, Rafaela Priscila;
Crop Breeding and Applied Biotechnology , 2011, DOI: 10.1590/S1984-70332011000300009
Abstract: the aim of this study was to characterize and estimate the genetic similarity among 93 cassava accessions. the dna amplification was performed with 14 microsatellite primers. the amplification products were separated by a polyacrylamide gel electrophoresis, showing a polymorphism formation, through which the accessions were discriminated against. the genetic similarity among accessions of cassava was estimated by the dice coefficient. cluster analysis was carried out using the upgma method. the polymorphic primers amplified a total of 26 alleles with 2-4 alleles per loci. the genetic similarity ranged from 0.16 to 0.96. the average values for observed and expected heterozygosity were 0.18 and 0.46, respectively. twenty genetic similarity clusters were determined, demonstrating diversity among accessions, suggesting the possibility of heterotic hybrid generation.

Flávia Fernandes Carneiro,Jo?o Bosco dos Santos,Paulo Roberto Carvalho Gon?alves,Rafaela Priscila Antonio
Crop Breeding and Applied Biotechnology , 2011,
Abstract: The objective of the research was to investigate the nature and magnitude of the genetic factors involved in theresistance of the common bean to white mold. The lines G122 (resistant) and M20 (susceptible) were crossed to yield F1 and F2generations and F2:3 progenies. The experiment was set up using the random block design with two replications, each of which wasevaluated twice with fungal inoculations being performed on 28 and 38 day-old plants using the straw test method. Six to eight daysafter inoculation evaluations were conducted on individual plants and at the level of means of progenies using a diagrammatic scaleranging from 1 to 9. The additive-dominance model adopted was efficient, and the genetic control of resistance was predominantlydue additive effects. Estimates of broad-sense heritability indicated that selection would be more efficient when based on the meansof progenies and when successive inoculations are employed.

Silva, Paulo Sérgio Lima e;Antonio, Rafaela Priscila;Mariguele, Keny Henrique;Silva, Kathia Maria Barbosa e;Lima, Lidiane Kely de;Silva, Júlio César do Vale;
Revista Brasileira de Fruticultura , 2007, DOI: 10.1590/S0100-29452007000300027
Abstract: apparently, there are no custard apple cultivars defined for the northeastern region of brazil. the establishment of breeding programs aimed at the selection of types from productive locations for later cloning is desirable. this work's objective was to evaluate the yield (during the first three crops) and quality (first crop) of fruits from 20 half-sibling custard apple tree progenies, selected from home orchards. an additional objective was to estimate genetic parameters for the traits evaluated. a micro sprinkling-irrigated experiment was conducted in mossoró-rn, brazil, as random blocks with five replications. in characteristics evaluated for periods longer than a year (diameter, height and mean weight of fruits, number of fruits ha-1 and fruit yield (kg ha-1), and a split-plot design was adopted, with progenies considered as plots and annual cropping seasons as subplots. the best progenies in terms of fruit yield (a3 and a4) are not necessarily the best for fruit dimensions and fruit mean weight (a2, fe4, jg1, jg2, sm1, sm7, and sm8). these progenies show great potential to be used in future studies on crosses or on vegetative propagation. in this regard, progeny jg2 should be highlighted as promising in terms of yield and fruit size. the progenies are not different with regard to percentages (in relation to mean fruit mass) of pericarp, endocarp, seeds, and receptacle, in the fruit, and fruit volume, number of seeds/fruit, and total soluble solids content in the fruit pulp, but progeny fe4 presents higher total titratable acidity in the fruit pulp. narrow-sense heritability estimates were relatively high for all characteristics in which there was variability between progenies, with higher values for number of fruits ha-1 (80 %) and fruit yield (78 %). relatively high coefficients of genotypic variation (around 20%) were observed for number of fruits ha-1 and fruit yield, with lower values for the other characteristics. there were positive genotypic and phenoty

Journal of Cancer Therapy (JCT) , 2013, DOI: 10.4236/jct.2013.47A009
Abstract:

Cancer is a leading cause of death worldwide, and is estimated to be the cause of 13.1 million deaths in 2030. Breast cancer is the second cancer in the global mortality ranking, considering both sexes. Due to the burden of breast cancer worldwide, this paper aims to present an overview of the main R&D efforts focusing on breast cancer treatment. Patents were retrieved from the Derwent Innovations Index?, which has a specific code for pharmaceuticals related to breast cancer. A total of 423 patent documents filed in recent years were identified, of which 126 are exclusively for breast cancer, 169 for breast cancer and other cancers, and 128 are inventions related to the treatment of cancer and other diseases. The patent documents were classified into two large groups, the first of which had a predominance of claims for antibodies, proteins and polypeptides for use in medication production, while the second focuses on gene therapy, nucleotides and RNA. The country with the majority of priority patent applications was found to be the United States, followed by China and Japan.

Abstract: Lack of time these days makes leisure moments increasingly valuable. While movies are an important entertainment option in big cities recently there have been changes in theaters around the world and many adaptations have been made to attract and retain viewers. This article addresses key attributes and motivations with respect to movies and theaters that influence moviegoers in Porto Alegre. Data analyzed reveals that the main moviegoer motivation is leisurely entertainment. Seating comfort and cleanliness are the most important attributes for motion picture theaters while cast and script rate highest for motion pictures. This information may influence more of a focus on actions for customer preferences in the endeavor to attract more viewers. La creciente falta de tiempo de las personas en los tiempos actuales ha dejado los momentos de ocio cada vez más valorados. La ida al cine es una de las principales opciones de entretenimiento de la población en las grandes ciudades.

A cultura da atividade e o trabalho com idosos
Priscila Zazyki Marques,Sergio Antonio Carlos
Revista Brasileira de Ciências do Envelhecimento Humano , 2006,
Abstract: Este artigo discute a valoriza o e a dissemina o da cultura do envelhecimento saudável, amplamente difundido nos trabalhos realizados com idosos e conseguido principalmente por meio da atividade física. A partir do entendimento das teorias do desengajamento e da atividade em trabalhos do campo da gerontologia, observamos que a teoria da atividade é usada como referência primeira para grande parte dos trabalhos com esta popula o no cenário atual. Tal perspectiva estimula uma “reprivatiza o da velhice”, como apontou Debert, e favorece a instala o de uma “cultura da atividade” (cultura segundo Clifford Geertz). Finalmente, a “teoria da vara” é usada a fim de tentar entender como o cenário do trabalho com idosos pode modificar-se daqui para frente com vistas à adequa o à heterogeneidade que marca essa faixa da popula o.
Aplicación de los requerimientos ambientales de ley en el desarrollo de los programas sísmicos en Sismopetrol S.A.
Pereira Poveda Vietnam Rafaela,Pinilla Agudelo Gabriel Antonio
Acta Biológica Colombiana , 2007,
Abstract: El manejo ambiental en una compa ía de sísmica se divide en dos campos diferentes: los trabajos en campo, que implican la generación de impactos ambientales directos y que contemplan da os potenciales mayores; y la gestión ambiental sobre las actividades de oficina y de almacenamiento de elementos. En los trabajos de campo, que corresponden al desarrollo de los programas sísmicos, el manejo ambiental debe sujetarse a lo estipulado en la Guía Básica Ambiental para Programas de Exploración Sísmica Terrestre (MAVDT, Res 1023/2005); documento en el cual se discriminan las actividades de manejo ambiental según las etapas del programa sísmico, a saber: Planificación del Programa; Fase Pre-Operativa; Desarrollo del Programa (Adecuación de campamentos, Trocha y topografía, Perforación y cargado de pozos, Regado de cables, Registro); Desmantelamiento y Restauración y Abandono del área. Todas estas fases generan información sobre el manejo ambiental y sobre la dinámica específica de cada área en la que se desarrollan los procesos. Dicha información se articulaba a los reportes de los otros departamentos para generar un informe que documente la totalidad del proceso. Para las actividades de oficina y de almacenamiento de elementos en la sede administrativa principal (la Base SP-300), ubicada en Bogotá; se cuenta con el PACA (Plan de Acción y Cumplimiento Ambiental), que detalla los programas y cada una de las actividades que se adelantan dentro SGA (Sistema de Gestión Ambiental), y que está dise ado acorde a las necesidades de la organización y en concordancia con la legislación nacional y local vigente. El PACA para Bogotá consta de cuatro programas que se desarrollan de manera simultánea en todas las dependencias y a todos los niveles de la organización: Manejo de Residuos; Orden, Aseo y Manejo de Recursos; Manejo de Emergencias, que contiene su respectivo Plan de Contingencia; Cumplimiento de la Normatividad Ambiental Vigente; Programa de Evaluación, Capacitación y Seguimiento al Personal; y Seguimiento a procesos/actividades. Todas las actividades tienen un seguimiento, para verificar el correcto manejo de cada una. Para avalar el buen manejo de todas las actividades, en los programas se invita a la autoridad ambiental competente a que realice al menos una visita. En este artículo se ocumentan las labores que implica la gestión ambiental en este tipo de actividades económicas y se discute sobre algunas posibilidades de mejora. Se analiza también el papel del Biólogo en este tipo de actividades.
