Diversidad de frijoles nativos de diferentes regiones del estado de Puebla Native beans diversity of different regions from state of Puebla
Ana Rosa Ramírez-Pérez,Ramón Díaz-Ruiz,Carmen Jacinto-Hernández,Juan Alberto Paredes-Sánchez
Revista mexicana de ciencias agrícolas , 2012,
Abstract: El frijol común representa un cultivo básico en México con una gran variabilidad en sus características morfológicas. En estudios sobre la diversidad genética se han usado marcadores moleculares, entre los que se encuentran los RAPD. El presente trabajo tuvo como objetivo caracterizar mediante caracteres morfológicos, agronómicos, de calidad y marcadores RAPD, variedades de frijoles nativos cultivadas en diferentes comunidades del estado de Puebla. La extracción de ADN se realizó en una muestra de hojas jóvenes de las variedades sembradas bajo invernadero. Se utilizaron 7 iniciadores RAPDs de la serie OPERON Technologies. Las bandas polimórficas se codificaron por presencia y ausencia. Con el programa NTSYS pc 2.2 se generó un dendograma empleando el índice de similitud de Dice, con nivel de corte a un valor de 0.48, donde se definieron 13 grupos. Seis grupos estuvieron integrados por una variedad, 4 grupos por 2 variedades, 2 grupos por 3 variedades y un grupo formado por 7 variedades. Los grupos definidos se integraron por colores de grano distintos y coincidieron en otras características morfológicas como días a floración, tiempo de cocción y contenido de proteína. Common bean is basic crop in Mexico with great variability in its morphological characteristics. RAPD is among molecular markers, which have been used in studies about genetic diversity. The aim of this work was to characterize by morphological, agronomical, quality characters and RAPD markers the varieties harvested in different localities from state of Puebla. DNA extraction was made from sample of young leaves of varieties planted under greenhouse. 7 RAPDs starters from OPERON Technologies were used. Polymorphical bands were coded by presence and absence. With NTSYS pc 2.2 software dendrogram was created using Dice's similarity index, with cut level at value of 0.48 where 13 groups were defined. Six groups were comprised by single variety, 4 groups by 2 varieties, 2 groups by 3 varieties and one group by 7 varieties. The defined groups were comprised by different grain colors and coincided in other morphological characteristics like days to flowering, cooking time and protein content.

Elio Cruz Manzano,Eslhey Sánchez Domínguez,María del Carmen Paredes Pérez,Dayne álvarez Ramírez
Revista Cubana de Salud Pública , 2003,
Abstract: El objetivo de este trabajo fue evaluar el estado nutricional de adultos mayores con respecto a algunos micronutrientes, en un consultorio médico de familia. Se estudiaron 24 hombres y 28 mujeres con edades comprendidas entre 60 y 91 a os, mediante indicadores dietéticos y bioquímicos. La evaluación dietética se realizó mediante una encuesta semicuantitativa de frecuencia de consumo de alimentos. En el suero sanguíneo se determinó la concentración de las vitaminas A, E, C, del betacaroteno y del cinc. El estado de las vitaminas A y E, así como del betacaroteno, no mostró problemas; sin embargo, solo el 28,5 % de los individuos tuvo valores adecuados de vitamina C y el 46 % estaba en hipocincemia. Se hacen recomendaciones para orientar una educación alimentaria y nutricional Consumption and serum levels of micronutrients in older adults from a family physician's office. This paper was aimed at evaluating the nutritional status of older adults in relation to certain micronutrients at a family physician's office. 24 men and 28 women aged 60-91 were studied by using dietetic and biochemical indicators. Diet evaluation was made through a semiquantitative survey on food consumption frequency. The concentration of vitamins A, E. C, betacarotene and zinc in blood serum were determined. The state of vitamins A, E and C and of betacarotene had no problems; however, only 28.5 % of the individuals had adequate values of vitamin C and 46 % had low levels of zinc in blood. Recommendations were made to establish a food and nutritional education

Revista Cubana de Investigaciones Biom??dicas , 2004,
Abstract: twenty four men and twenty eight females aged 60 to 91 years were studied to evaluate the antioxidant status and the oxidative damage indicators of an elderly population in las tunas province. concentration in blood serum of non enzymatic antioxidants such as vitamin a, b carotene, vitamin e, vitamin c, and zinc; the activity of antioxidant enzymes superoxide dismutase and catalase as well as concentration of indicators of oxidative damage, malondialdehyde and oxidized proteins were determined. except for vitamin c and zinc for the whole population and the females respectively, the rest of antioxidant indicators are within the reported normal ranges. the states of vitamin c and zinc are deficient in a high percentage of individuals whereas the activity of antioxidant enzymes is higher in older adults. however, the concentration of oxidative damage indicators are within the normal limits, which may indicate compensated oxidative stress
Restricciones funcionales en la elisión del Marcador de Plural en el Espa?ol de Caracas
Ruiz Sánchez,Carmen;
Boletin de Linguistica , 2005,
Abstract: this work analyzes and explains the functional factors constraining the deletion of plural /-s/ in caracas spanish. regarding the codification and analysis of the data, the study follows poplack?s approach (1980) with the aim of demonstrating that the deletion of the plural marker depends on the complex combination of morphological, semantic and syntactic factors, supporting a new interpretation of kiparsky?s functional hypothesis (1972), in which the importance of contextual elements is taken into account. the results show a tendency to retain /-s/ in the first element of the np and in the nps in which the only indication of plurality is the phonetic realization of the plural morpheme, and to delete it when there is additional information of plurality in the sentence. it is also argued that a more general functional approach can explain the behavior of plural /-s/ in a more consistent and clear manner than a purely functionalist one at the np level or than one based on the effect of parallelism in the np (pereira scherre 2001).
Las copas tipo Cástulo en la Península Ibérica
Sánchez, Carmen
Trabajos de Prehistoria , 1992,
Abstract: The Castulo cup is one of the most common black glaze Attic forms in the Iberian Peninsula from the Atlantic coast to Ampurias. Their date in the Iberian Peninsula is some years later than that proposed for Athens. They did not appear till some years after the second half of the 5th c. B.C. Their production probably continued until the first quarter of the 4th century B.C. They are almost fixed in their form for about a century, but some differences in the outside decoration and the underside of the foot can be pointed out. Two main types are proposed for the second half of the 5th century and the first quarter of the 4th century B.C. The differences in date compared with those found at Athens can be explained as an adaptation of the workshops to the demands of Iberian customers. Athen's artisans continued making Castulo cups for export at a time when in Athens they did not use them any more, because the stemless cup had been replaced by the popular kantharoi and cup-kantharoi. La copa Cástulo es una de las formas áticas de barniz negro más abundante en los yacimientos peninsulares desde la costa atlántica hasta Ampurias. Su cronología es en la Península Ibérica algo posterior a la propuesta para Atenas. No aparecen hasta algo después de mediados del siglo V y probablemente se continúan fabricando hasta el primer cuarto del IV a. C. No experimentan durante casi un siglo de producción ninguna variación formal, sin embargo sí se pueden ver diferencias en el tratamiento de la decoración exterior y del fondo externo. Se proponen aquí fundamentalmente dos tipos de la segunda mitad del siglo V y primer cuarto del IV a. C. La diferencia cronológica con las halladas en Atenas se explica como una adaptación de los talleres áticos a la demanda de los clientes ibéricos. Los artesanos atenienses continúan fabricando copas Cástulo para la exportación cuando en Atenas se han dejado ya de utilizar las copas de pie bajo al ser sustituidas por una forma muy popular en Atenas y que sin embargo en muchos yacimientos ibéricos peninsulares casi no aparece: los cántaros.
Cartas al Papa : modelos epistolares en los manuales de correspondencia de los siglos XVI-XVII
Carmen Serrano Sánchez
Via Spiritus : Revista de História da Espiritualidade e do Sentimento Religioso , 2011,
Abstract: The spreading of letter-writing and its social implication during the Modern Age resulted in the appearance of books in vernacular languages to learn how to write a letter correctly from the mid-Sixteenth century in Spain, as well as the rest of Europe. Among the varied examples offered to the readers to adapt their correspondence to the customs and conventions of this time, it’s possible to find some letters directed to the Pope, who certainly had to be one of the most demanding addressees. In these treatises the Pontiff not only appears as the absent to whom the missives are written, but he also sometimes takes the quill. This collection of model letters makes up a imaginary correspondence that must be studied from the perspective of the epistolary theory, analyzing the typologies of letters proposed, the epistolary topics and themes allowed – the matters that could be discussed directly with the Pope, and those other ones that required intermediaries –, the authorized senders and their self-representative strategies on the paper.
Antibióticos, ayer, hoy y ma ana ?
Carmen Sánchez de Rivas
Química Viva , 2006,
Abstract: Los antibióticos (AB) son compuestos relativamente sencillos, producidos por bacterias u hongos que atacan específicamente a las bacterias. Interfieren en algún paso del metabolismo donde encuentran un blanco adecuado. Desde el descubrimiento de la penicilina, se han descubierto una docena de nuevos tipos de AB y optimizado o sintetizado cerca de una centena. Sin embargo, su eficacia se ha visto alterada por su uso excesivo o incorrecto, que conduce a la aparición y diseminación de bacterias resistentes (ABR). Estas ABR actúan impidiendo el ingreso, modificando o inactivando la droga, modificando al blanco, o activando los sistemas de enflujo. La gran capacidad de las bacterias de mutar y transferir genes, y la presencia de genes de resistencia esencialmente en plásmidos y transposones, contribuyen a su diseminación tanto entre bacterias emparentadas y/o patógenas como hacia bacterias no patógenas que son los reservorios de ABR. La sensación de haber perdido la batalla o de que las ganancias a futuro no son tan importantes, han disminuido el interés de los laboratorios farmacéuticos por buscar nuevos compuestos. Sin embargo desde la investigación básica aparecen nuevas alternativas ya sea utilizando la genómica como material de análisis de nuevos blancos, las defensas naturales del organismo huésped, u otros agentes olvidados como las bacterias predadoras y los fagos, ambos capaces de destruir bacterias.
Medicine and health information in Galician daily press. The health news in the main Galician newspapers
Lic. Carmen Costa Sánchez
Revista Latina de Comunicación Social , 2008,
Abstract: The aim of this paper is to study the health and medicine information published during a week in the four newspapers more spreaded in Galicia. The journalism has the responsibility of informing about health with quality criterions, instead of considering health a superficial, anecdotic and secondary subject. The appearance of the specific sections and the incorporation of the journalists specialized in health to the editorial staffs of the Spanish main generalist newspapers are beginning a process in depth in this way. But what is happening with the press of the autonomous regions? Which is the informative processing of medicine and health information in Galician daily press?, we asked. Descriptive, quantitative and content analysis will make possible to think about the information coverage of this kind of facts for making a diagnostic of the situation and for proposing its necessary improvement.
