Genome-wide analysis of uncapped mRNAs under heat stress in Arabidopsis
No full textAbstractRecently, we have showed that Tudor Staphylococcal Nuclease (TSN or Tudor-SN) proteins (TSN1 and TSN2) are localized in cytoplasmic messenger ribonucleoprotein (mRNP) complexes called stress granules (SG) and processing bodies (PB) under heat stress in Arabidopsis. One of the primary functions of these mRNP complexes is mRNA decay, which generates uncapped mRNAs by the action of endonucleases and decapping enzymes (Thomas et al., 2011) [1]. In order to figure out whether TSN proteins could be implicated in mRNA decay, we isolated uncapped and total mRNAs of Wild type (WT; Col and Ler) and TSN double knock-out (tsn1tsn2) seedlings grown under heat stress (39°C for 40min) and control (23°C) conditions. Here, we provide the experimental procedure to reproduce the results (NCBI GEO accession number GSE63522) published by Gutierrez-Beltran et al. (2015) in The Plant Cell [2]

ROBERT E. PARK: Sociología, comunidad y sociedad (Presentación: Emilio M. Martínez Gutierrez)
No full textRobert Park’s institutional and scientific works are part of the most suggestive periods of sociological research. He completed the empirical turn that the department of Sociology at University of Chicago started, especially in William Thomas’ perspective, and this contribution improved the scientific statute of sociology. His development of human (and urban) ecology proposes new theoretical and methodological frameworks of analysing social and territorial processes 174 emilio martínez gutiérrez la investigación ecológica… EMPIRIA.

Moreover, his approach has improved different particular techniques and procedures (widespread at present) as, for instance, ecological cartography (morphological level) and qualitative techniques that study social interactions (cultural or moral level).Los trabajos cientificos e institucionales de Robert Park marcan uno de los periodos mas sugerentes de la investigacion sociologica. Park completa el giro empirico iniciado por la primera generacion del departamento de sociologia de la Universidad de Chicago, sobre todo con William Thomas, contribuyendo notablemente al reconocimiento del estatuto cientifico de la sociologia. Con el desarrollo de la ecologia urbana propone un marco global, teorico-metodologico, de interpretacion y analisis de los procesos sociales y territoriales de las comunidades locales que desemboca en procedimientos tecnicos particulares, de amplia difusion en la actualidad, desde la cartografia ecologica —en el plano morfologico— a las tecnicas cualitativas de estudio de las interacciones sociales —en el plano cultural.

La obra poetica de Vicenta Maturana de Gutierrez
No full textThe reason for studying Vicenta Maturana de Gutierrez (1793-1859) is to recuperate the poetry of a totally ignored woman writer whose literary activity was intense during the first half of the 19th century.Vicenta Maturana de Gutierrez published both poetry and prose, which ranged in style from Neoclassic to Romantic. Although she was the author of two romantic novels, Teodoro o el huerfano agradecido (1825) and Sofia y Enrique (1829), it is her poetic compositions, Ensayos poeticos, which are the subject of this study. Her Ensayos poeticos were published in three different editions in 1828, 1841, and 1859; they favor pastoral themes and deal with such topics as nature, friendship, and social criticism. Her poetry indicates a clear preference for the neoclassic poetic style; however, it was also influenced by a romantic subjectivity in so far as it expresses feelings such as melancholy and pain. In addition, her poetry displays a feminine consciousness, one that adds a distinctive feature to her work which was written at a time when few women writers dared to voice their rights as women.The main focus of the dissertation is to present an outline of the life and works of Vicenta Maturana de Gutierrez; to analyze the poems of the three editions of Ensayos poeticos; and to discuss in depth her collection of poetic prose, Himno a la luna, published in 1838. The dissertation consists of an introduction, four chapters, and a conclusion. Chapter One gives an account of the life and works of the poet, and it discusses her attitudes toward poetic creation. Chapter Two defines the characteristics and major themes of her poetry. Chapter Three discusses Himno a la luna and provides an account of the influence it received from the French writer Reyrac, author of the prose-poem Hymne au soleil. Chapter Four analyzes Vicenta Maturana de Gutierrez' style and versification. A conclusion argues that Vicenta Maturana de Gutierrez deserves attention for her early feminism and for the fact that she bridges the gap between neoclassic and romantic Spanish poetry.Made available in DSpace on 2011-05-07T13:07:59Z (GMT).
