New genetic loci link adipose and insulin biology to body fat distribution.

Body fat distribution is a heritable trait and a well-established predictor of adverse metabolic outcomes, independent of overall adiposity. To increase our understanding of the genetic basis of body fat distribution and its molecular links to cardiometabolic traits, here we conduct genome-wide association meta-analyses of traits related to waist and hip circumferences in up to 224,459 individuals. We identify 49 loci (33 new) associated with waist-to-hip ratio adjusted for body mass index (BMI), and an additional 19 loci newly associated with related waist and hip circumference measures (P < 5 × 10(-8)). In total, 20 of the 49 waist-to-hip ratio adjusted for BMI loci show significant sexual dimorphism, 19 of which display a stronger effect in women. The identified loci were enriched for genes expressed in adipose tissue and for putative regulatory elements in adipocytes. Pathway analyses implicated adipogenesis, angiogenesis, transcriptional regulation and insulin resistance as processes affecting fat distribution, providing insight into potential pathophysiological mechanisms.

La llengua de l'enemic com a llengua pròpia: cultures translatives del paisatge indígena nord-americà

This research paper seeks to bring into view the present-day situation of Native-American narrative in English. It is divided into four chapters. The first deals with the emergence of what we might call a Native-American narrative style and its evolution from 1900 up until its particularly forceful expression in 1968 with the appearance of N. Scott Momaday’s novel House Made of Dawn. To trace this evolution, we follow the chronology set forth by Paula Gunn Allen in her anthology Voice of the Turtle: American Indian Literature 1900-1970. In the second chapter we hear various voices from contemporary Native-American literary production as we follow Simon J. Ortiz’s anthology Speaking for the Generations: Native Writers on Writing. Noteworthy among these are Leslie Marmon Silko and Gloria Bird, alongside new voices such as those of Esther G. Belin and Daniel David Moses, and closing with Guatemalan-Mayan Victor D. Montejo, exiled in the United States. These writers’ contributions gravitate around two fundamental notions: the interdependence between human beings and the surrounding landscape, and the struggle for survival, which of necessity involves the deconstruction of the (post-)colonial subject. The third chapter deals with an anthology of short stories and poems by present-day Native-American women writers, edited by Joy Harjo and Gloria Bird and entitled Reinventing the Enemy’s Language: Contemporary Native Women’s Writings of North America. It too exemplifies personal and cultural reaffirmation on a landscape rich in ancestral elements, but also where one’s own voice takes shape in the language which, historically, is that of the enemy. In the final chapter we see how translation studies provide a critical perspective and fruitful reflection on the literary production of Native-American translative cultures, where a wide range of writers struggle to bring about the affirmative deconstruction of the colonialised subject. Thus there comes a turnaround in the function of the “enemy’s language,” giving rise also to the question of cultural incommensurability.

Gauge transformations in Einstein-Yang-Mills theories

We discuss the relation between spacetime diffeomorphisms and gauge transformations in theories of the YangMills type coupled with Einsteins general relativity. We show that local symmetries of the Hamiltonian and Lagrangian formalisms of these generally covariant gauge systems are equivalent when gauge transformations are required to induce transformations which are projectable under the Legendre map. Although pure YangMills gauge transformations are projectable by themselves, diffeomorphisms are not. Instead, the projectable symmetry group arises from infinitesimal diffeomorphism-inducing transformations which must depend on the lapse function and shift vector of the spacetime metric plus associated gauge transformations. Our results are generalizations of earlier results by ourselves and by Salisbury and Sundermeyer. 2000 American Institute of Physics.

Aarskog-Scott syndrome: clinical update and report of nine novel mutations of the FGD1 gene.

Mutations in the FGD1 gene have been shown to cause Aarskog-Scott syndrome (AAS), or facio-digito-genital dysplasia (OMIM#305400), an X-linked disorder characterized by distinctive genital and skeletal developmental abnormalities with a broad spectrum of clinical phenotypes. To date, 20 distinct mutations have been reported, but little phenotypic data are available on patients with molecularly confirmed AAS. In the present study, we report on our experience of screening for mutations in the FGD1 gene in a cohort of 60 European patients with a clinically suspected diagnosis of AAS. We identified nine novel mutations in 11 patients (detection rate of 18.33%), including three missense mutations (p.R402Q; p.S558W; p.K748E), four truncating mutations (p.Y530X; p.R656X; c.806delC; c.1620delC), one in-frame deletion (c.2020_2022delGAG) and the first reported splice site mutation (c.1935+3A>C). A recurrent mutation (p.R656X) was detected in three independent families. We did not find any evidence for phenotype-genotype correlations between type and position of mutations and clinical features. In addition to the well-established phenotypic features of AAS, other clinical features are also reported and discussed.

Avaliação da fertilidade dos solos de sistemas agroflorestais com cafeeiro (Coffea arabica L.) em Lavras-MG

Com o objetivo de avaliar a fertilidade dos solos em um sistema agroflorestal composto por cafeeiros (Coffea arábica L. - Mundo Novo), ingazeiros (Inga vera Willd) e grevíleas (Grevilea robusta A. Cunn), situado em Lavras, Minas Gerais, foi instalado o presente experimento. Usou-se um delineamento experimental inteiramente casualizado com três tratamentos e sete repetições. Os tratamentos foram: a) cafeeiros a pleno sol, b) cafeeiros consorciados com ingazeiros e c) cafeeiros consociados com grevílea. Os espaçamentos dos cafeeiros nos três sistemas foi 4 x 1 m, para o ingazeiro 8 m x 15 m e para a grevílea 12 m x 10 m. Aos 15 anos de idade do cafeeiro e do ingazeiro e aos 9 anos da grevílea foram avaliadas as seguintes características dos solos, pH, acidez potencial (H+Al), alumínio trocável (Al+3), bases trocáveis (Ca+2 e Mg+2), potássio disponível (K+), fósforo disponível(P), enxofre (S), CTC efetiva (T), soma de bases (SB), saturação de bases (V) e matéria orgânica (MO). Os resultados foram submetidos à analise de variância e as médias, comparadas pelo teste de Scott-Knott. Após a análise dos dados, concluiu-se que, embora tenha havido diferenças entre alguns elementos estudados, as características químicas dos solos nos três sistemas não foram severamente afetadas.

Efeito do espaçamento e da idade sobre variáveis de povoamentos de Pinus Taeda L.

O objetivo deste estudo foi analisar os dados de um experimento sobre espaçamento inicial, implantado em povoamentos de Pinus taeda L. não-desbastados pertencentes à empresa IGARAS, localizados no Planalto Serrano do Estado de Santa Catarina, no Sul do Brasil. O experimento consistiu em um delineamento em blocos casualizados com três repetições e nove tratamentos (espaçamentos 1,5 x 1,0; 2,0 x 1,0; 2,5 x 1,0; 1,5 x 2,0; 2,0 x 2,0; 1,5 x 3,0; 2,5 x 2,0; 2,0 x 3,0; e 2,5 x 3,0 m). As medições foram realizadas nas idades de 4 a 14 anos. O efeito dos espaçamentos e da idade sobre as variáveis do povoamento foi analisado por meio do teste de Scott-Knot e de análise de regressão. Os resultados apontaram que os espaçamentos influenciam a tendência de crescimento em altura total, em área basal por ha, em diâmetro quadrático, em volume por árvore e em volume por ha. Os resultados permitiram confirmar que o espaçamento possui pouco efeito sobre as estimativas de altura total e que, aos 14 anos, os maiores espaçamentos proporcionam maiores estimativas de diâmetro quadrático, de volume por árvore e de sobrevivência e menores estimativas de área basal por ha e de volume por ha.

Assessment of silver-stained AFLP markers for studying DNA polymorphism in proso millet (Panicum miliaceum L.)

Proso millet (Panicum miliaceum L.) is a serious weed in North America. A high number of wild proso millet biotypes are known but the genetic basis of its phenotypic variation is poorly understood. In the present study, a non-radioactive silver staining method for PCR-Amplified Fragment Length Polymorphism (AFLP) was evaluated for studying genetic polymorphism in American proso millet biotypes. Twelve biotypes and eight primer combinations with two/three and three/three selective nucleotides were used. Pair of primers with two/three selective nucleotides produced the highest number of amplified DNA fragments, while pair of primers with three/three selective nucleotides were more effective for revealing more polymorphic DNA fragments. The two better primer combinations were EcoR-AAC/Mse-CTT and EcoR-ACT/Mse-CAA with seven and eleven polymorphic DNA fragments, respectively. In a total of 450 amplified fragments, at least 339 appeared well separated in a silver stained acrylamide gel and 39 polymorphic DNA bands were scored. The level of polymorphic DNA (11.5%) using only eight pairs of primers were effective for grouping proso millet biotypes in two clusters but insufficient for separating hybrid biotypes from wild and crop. Nevertheless, the present result indicates that silver stained AFLP markers could be a cheap and important tool for studying genetic relationships in proso millet.

Potencial fisiol��gico em sementes de cultivares de feijão crioulo (Phaseolus vulgaris L.)

O trabalho foi realizado com o objetivo de caracterizar genótipos crioulos quanto ao potencial fisiol��gico das sementes. As sementes foram obtidas na safra 2007/2008, com 26 genótipos, no município de Lages - SC. Para analisar a qualidade das sementes, determinou-se o porcentual de germinação inicial e após o envelhecimento acelerado, massa de 100 sementes, condutividade el��trica, comprimento da raiz primária e emergência a campo. Os genótipos foram separados em classes com base no teste Scott-Knott e os genótipos crioulos também foram comparados com a testemunha (cultivares comerciais) pelo teste de Dunnett, os quais permitiram, com base em todos os parâmetros avaliados, indicar os genótipos BAFs 36, 55, 75, 102 como os de elevado potencial fisiol��gico. Particularmente nas condições de emergência a campo, a maioria dos genótipos apresenta ampla adaptação ambiental, com exceção dos BAFs 4, 7, 23. Pelo estudo de correlação, observou-se uma associação positiva entre o porcentual de germinação inicial com o comprimento de raiz primária e negativa com a massa de 100 sementes. Esta associação foi devido ao genótipo, o que permite indicar que os genótipos com menor massa de 100 sementes foram os mais vigorosos.

D'objet de risée à symbole de l'Amérique : la tél��vision à travers le cinéma américain (1970 à 1999)

Cette analyse dresse le portrait des différentes représentations de la tél��vision à travers le cinéma américain de 1970 à 1999. Ce travail porte sur un corpus de quatorze films et s’intéresse à quatre dimensions de la tél��vision : l���appareil électrique, le tél��spectateur, le contenu et l���univers professionnel. Les hypothèses soulevées sont que la tél��vision est majoritairement présentée de façon négative, que les représentations s’inscrivent dans un contexte culturel précis et qu’il y a un consensus entre les écrits universitaires et les cinéastes au sujet de l���écran cathodique. Bien que certaines critiques soient récurrentes d’une décennie à l���autre, il y a une évolution des représentations. Dans les années 1970, la tél��vision est un objet de risée. Son contenu est caricaturé et les professionnels qui travaillent pour la tél��vision sont personnifiés comme des êtres incompétents. Dans les années 1980, le petit écran est montré comme un objet dangereux. Sa très grande popularité en ferait un puissant diffuseur idéologique qui transforme tout en spectacle même la mort. Cette même popularité servira de prétexte aux cinéastes des années 1990 pour utiliser la tél��vision comme symbole de l���Amérique. Le portrait est peu flatteur : une Amérique corrompue, violente et en manque d’idéaux. Cette analyse montre également qu’au fil des décennies, les mêmes idées circulent entre cinéastes et penseurs américains. Enfin, cette attitude par rapport à la tél��vision est d’ailleurs symptomatique d’un mépris de l���élite intellectuel envers l���art populaire.
