Effect of somatostatin on duodenal glucose absorption in man.

OBJECTIVE: The hyperglycemic hyperinsulinemic clamp technique using intraduodenally infused glucose is an attractive tool for studying postprandial glucose metabolism under strictly controlled conditions. Because it requires the use of somatostatin (SST), we examined, in this study, the effect of SST on intestinal glucose absorption. CONTEXT: Twenty-six normal volunteers were given a constant 3-h intraduodenal infusion of glucose (6 mg.kg(-1).min(-1)) labeled with [2-(3)H]glucose for glucose absorption measurement. During glucose infusion, 19 subjects received iv SST at doses of 10-100 ng.kg(-1).min(-1) plus insulin and glucagon, and seven subjects were studied under control conditions. In the controls, glucose was absorbed at a rate that, after a 20-min lag period, equaled the infusion rate. RESULTS: With all the doses of SST tested, absorption was considerably delayed but equaled the rate of infusion after 3 h. At that time, only 5 +/- 2% of the total amount of infused glucose was unabsorbed in the control subjects vs. 36 +/- 2% (P < 0.001) in the SST-infused subjects. In the latter, the intraluminal residue was almost totally absorbed within 40 min of the cessation of SST infusion. At the lowest dose of SST tested (10 ng.kg(-1).min(-1)), suppression of insulin secretion was incomplete. CONCLUSION: These properties of SST hamper the use of intraduodenal hyperglycemic hyperinsulinemic clamps as a tool for exploring postprandial glucose metabolism.

Política pública en Francia: prohibición general o parcial del velo integral en el territorio nacional: Proyecto de ley del martes 11 de mayo de 2010

La República francesa se ofende por los burkas y de los niqab deambulando por las calles. Ve a sus principios rectores de Liberté, Égalité, Fraternité mofados, a su democracia desafiada, a su convivencia arriesgada. Por ello, el Gobierno francés ha impulsado desde hace un año una política pública que persigue la prohibición del velo integral -llámese burka o niqab- en el conjunto del espacio público. Años atrás, Francia, país que tanto aprecia los debates, se vio inmersa en la cuestión más general de la identidad nacional desde las reacciones de las banlieues en el 2005. Y por ello, Nicolas Sarkosy, en su programa electoral camino de las presidenciales en el 2007, ya incluía como una prioridad el tema de los valores y principios genuinamente franceses y europeos. Y en esta perspectiva, el Ministerio de Inmigración añadió sus calificativos de Integración e Identidad Nacional. El burka en el espacio público ha asaltado los medios de comunicación y la sociedad en su conjunto, especialmente desde hace dos o tres años. Es un problema sin precedentes en las democracias asentadas -aunque podríamos recordar el motín de Esquilache en 1766 bajo el reinado de Carlos III- sin una Jurisprudencia asentada al respecto, ni un marco normativo que lo prevea directamente. Y por ello, la élite política se divide estos días entre los prudentes y los atrevidos, los que se conforman con una prohibición parcial y los que persiguen una prohibición absoluta. Se trata de una política pública atípica, pues los bienes afectados son en realidad valores, principios y conceptos abstractos. Es la República francesa y la cohesión social los que se ven desafiados. Veremos en un primer momento, la etapa de identificación como problema público y su inclusión en la agenda política, por ende desde un punto de vista técnico, analizaremos brevemente esta política pública Top down limitada, y en el último apartado compararemos los argumentos de las dos alternativas que dispone actualmente el Parlamento para aprobar o no una ley al respecto. Por su parte, la Comisión Parlamentaria alegará principios de índole más filosófica que pragmática, mientras que el Consejo de Estado se centrará exclusivamente en los términos jurídicos y en la Jurisprudencia reduciendo en gran medida el impulso inicial del Gobierno. Quedará por ver estos días de debate en l’Assemblée Nationale1 si la prohibición será total o parcial.

Homolonto: generating homology relationships by pairwise alignment of ontologies and application to vertebrate anatomy.

MOTIVATION: The anatomy of model species is described in ontologies, which are used to standardize the annotations of experimental data, such as gene expression patterns. To compare such data between species, we need to establish relations between ontologies describing different species. RESULTS: We present a new algorithm, and its implementation in the software Homolonto, to create new relationships between anatomical ontologies, based on the homology concept. Homolonto uses a supervised ontology alignment approach. Several alignments can be merged, forming homology groups. We also present an algorithm to generate relationships between these homology groups. This has been used to build a multi-species ontology, for the database of gene expression evolution Bgee.

Expérimentation générique et dialogisme intertextuel. Perrault, La Fontaine, Apulée, Straparola, Basile

EXPERIMENTATION GENERIQUE ET DIALOGISME INTERTEXTUEL: PERRAULT, LA FONTAINE, APULEIUS, STRAPAROLA AND BASILE. Les contes en vers et en prose de Perrault relèvent, selon l'hypothèse présentée dans cette étude, d'un dialogisme intertextuel très complexe avec les formes génériques du conte déjà existantes dans les littératures européennes. L'académicien s'adonne à une véritable «expérimentation générique » au cours de laquelle il crée de nouvelles formes génériques, de nouvelles intrigues et de nouvelles figures à partir de la fabella de Psyché enchâssée dans les Métamorphoses d'Apulée, et de sa récriture galante par La Fontaine dans Les Amours de Psiché et de Cupidon en 1669. Ce double dialogue intertextuel est encore sous-tendu par le recours aux favole de Straparola (Le Piacevole notti) et aux cunti (Lo cunto de li cunti) de Basile, célèbres narrateurs italiens, qui avaient déjà reconfiguré de façon originale certains épisodes et personnages de la fabella de Psyché. Ce processus dialogique complexe est ici mis en évidence par l'analyse (inter)textuelle successive des trois premiers contes en prose, La Belle au bois dormant, Le Petit Chaperon rouge et La Barbe bleue. L'analyse comparative montre que Perrault les invente à partir des trois moments successifs de l'épreuve la plus difficile que Vénus inflige à Psyché, celle de la descente aux Enfers. En introduisant des différences significatives par rapport aux textes latins, italiens et français, l'académicien parvient à créer une nouvelle variation générique : le conte pseudo-naïf doté d'un sens crypté qui se découvre « plus ou moins selon le degré de pénétration de ceux qui les lisent ».GENERIC EXPERIMENTATION AND INTERTEXTUAL DIALOGISM: PERRAULT, LA FONTAINE, APULEIUS, STRAPAROLA AND BASILEAccording to Ute Heidmann, Perrault's tales have very complex inter- textual relations with other generic forms which already existed in other European literatures. Heidmann demonstrates here how Perrault experi- ments "generically" with the fairy tale and how he creates new generic forms from other tales by Apuleus, Straparola, Basile, or La Fontaine. This dialogic process is here underlined by the analysis of three particular fairy tales, Sleeping Beauty in the Woods, Little Red Riding Hood and Blue Beard. Heidmann shows how, by introducing key differences with the Latin, Italian and French models, Perrault succeeds in creating a new generic variation of the fairy tale: "the pseudo-naïve fairy tale".

Les Variacions Goldberg

L’Ària amb diverses variacions BWV 988, quarta part dels Clavier-übung, de Johann Sebastian Bach, és una obra que ha estat objecte de molts estudis. La seva extrema bellesa, el sobrenom amb què avui la coneixem, Variacions Goldberg -a partir de la llegenda que explica Forkel sobre un comte que patia insomni i el seu clavecinista Goldberg- i la seva estructura interna tan perfectament calculada, alhora que generadora de grans preguntes complexes de respondre, fan d’aquesta obra un mite indiscutible de la literatura per a teclat que, des de fa més 250 anys, ens continua fascinant i la fa immortal. Aquest treball és una humil aproximació a aquests aspectes, que ens faran acostar-nos al món interior d’aquesta obra.

Age-specific incidence of all neoplasms after colorectal cancer.

PURPOSE: Patients diagnosed with a specific neoplasm tend to have a subsequent excess risk of the same neoplasm. The age incidence of a second neoplasm at the same site is approximately constant with age, and consequently the relative risk is greater at younger age. It is unclear whether such a line of reasoning can be extended from a specific neoplasm to the incidence of all neoplasms in subjects diagnosed with a defined neoplasm. METHODS: We considered the age-specific incidence of all non-hormone-related epithelial neoplasms after a first primary colorectal cancer (n = 9542) in the Vaud Cancer Registry data set. RESULTS: In subjects with a previous colorectal cancer, the incidence rate of all other epithelial non-hormone-related cancers was stable around 800 per 100,000 between age 30 and 60 years, and rose only about twofold to reach 1685 at age 70 to 79 years and 1826 per 100,000 at age 80 years or older. After excluding synchronous cancers, the rise was only about 1.5-fold, that is, from about 700 to 1000. In the general population, the incidence rate of all epithelial non-hormone-related cancers was 29 per 100,000 at age 30 to 39 years, and rose 30-fold to 883 per 100,000 at age 70 to 79 years. Excluding colorectal cancers, the rise of all non-hormone-related cancers was from 360 per 100,000 at age 40 to 49 years to 940 at age 70 to 79 years after colorectal cancer, and from 90 to 636 per 100,000 in the general population (i.e., 2.6- vs. 7.1-fold). CONCLUSIONS: The rise of incidence with age of all epithelial non-hormone-related second cancers after colorectal cancer is much smaller than in the general population. This can possibly be related to the occurrence of a single mutational event in a population of susceptible individuals, although alternative models are plausible within the complexity of the process of carcinogenesis.

Temperament in Bach’s Well-tempered clavier: a historical survey and a new evaluation according to dissonance theory

After a historical survey of temperament in Bach’s Well-Tempered Clavier by Johann Sebastian Bach, an analysis of the work has been made by applying a number of historical good temperaments as well as some recent proposals. The results obtained show that the global dissonance for all preludes and fugues in major keys can be minimized using the Kirnberger II temperament. The method of analysis used for this research is based on the mathematical theories of sensory dissonance, which have been developed by authors such as Hermann Ludwig Ferdinand von Helmholtz, Harry Partch, Reinier Plomp, Willem J. M. Levelt and William A. Sethares

Pathology and first report of natural infections of the eye trematode Philophthalmus lachrymosus Braun, 1902 (Digenea, Philophthalmidae) in a non-human mammalian host

The avian eye trematode Philophthalmus lachrymosus Braun, 1902 is for the first time referred naturally occurring in a non-human mammalian host. Previously, natural infections with P. lachrymosus and other species of Philophthalmus have been occasionally reported from man, with few data on experimental infections of non-human mammals. Results presented here are related to the report of two cases of philophthalmosis due to natural infections of wild Brazilian capybaras, Hydrochaeris hydrochaeris L., 1766 with P. lachrymosus and associated pathology. Clinical signs, gross and microscopic lesions as well as new morphometric data on the parasite are presented.

In Vivo Systematic Analysis of Candida albicans Zn2-Cys6 Transcription Factors Mutants for Mice Organ Colonization.

The incidence of fungal infections in immuno-compromised patients increased considerably over the last 30 years. New treatments are therefore needed against pathogenic fungi. With Candida albicans as a model, study of host-fungal pathogen interactions might reveal new sources of therapies. Transcription factors (TF) are of interest since they integrate signals from the host environment and participate in an adapted microbial response. TFs of the Zn2-Cys6 class are specific to fungi and are important regulators of fungal metabolism. This work analyzed the importance of the C. albicans Zn2-Cys6 TF for mice kidney colonization. For this purpose, 77 Zn2-Cys6 TF mutants were screened in a systemic mice model of infection by pools of 10 mutants. We developed a simple barcoding strategy to specifically detect each mutant DNA from mice kidney by quantitative PCR. Among the 77 TF mutant strains tested, eight showed a decreased colonization including mutants for orf19.3405, orf19.255, orf19.5133, RGT1, UGA3, orf19.6182, SEF1 and orf19.2646, and four an increased colonization including mutants for orf19.4166, ZFU2, orf19.1685 and UPC2 as compared to the isogenic wild type strain. Our approach was validated by comparable results obtained with the same animal model using a single mutant and the revertant for an ORF (orf19.2646) with still unknown functions. In an attempt to identify putative involvement of such TFs in already known C. albicans virulence mechanisms, we determined their in vitro susceptibility to pH, heat and oxidative stresses, as well as ability to produce hyphae and invade agar. A poor correlation was found between in vitro and in vivo assays, thus suggesting that TFs needed for mice kidney colonization may involve still unknown mechanisms. This large-scale analysis of mice organ colonization by C. albicans can now be extended to other mutant libraries since our in vivo screening strategy can be adapted to any preexisting mutants.
