Los Amantes de Teruel: De la leyenda al teatro español de los siglos XVIII y XIX

Este trabajo de investigación abarca el desarrollo de la leyenda “Los Amantes de Teruel” en el teatro español de los siglos XVIII y XIX empezando con los primeros textos escritos. El desarrollo de la leyenda se analiza haciendo una comparación de los textos según las características del género. Las versiones que se estudian son los melodramas de Francisco Mariano Nifo, y Francisco Comella, la tragedia anónima, los dos dramas de Hartzenbusch que se escribieron en las diferentes fechas (1836-1849) y el drama lírico de Tomás Bretón.

Resting metabolic rate and protein turnover in apparently healthy elderly Gambian men.

Body composition, resting energy expenditure (REE), and whole body protein metabolism were studied in 26 young and 28 elderly Gambian men matched for body mass index during the dry season in a rural village in The Gambia. REE was measured by indirect calorimetry (hood system) in the fasting state and after five successive meals. Rates of whole body nitrogen flux, protein synthesis, and protein breakdown were determined in the fed state from the level of isotopic enrichment of urinary ammonia over a period of 12 h after a single oral dose of [15N]glycine. Expressed in absolute value, REE was significantly lower in the elderly compared with the young group (3.21 +/- 0.07 vs. 4.04 +/- 0.07 kJ/min, P < 0.001) and when adjusted to body weight (3.29 +/- 0.05 vs. 3.96 +/- 0.05 kJ/min, P < 0.0001) and fat-free mass (FFM; 3.38 +/- 0.01 vs. 3.87 +/- 0.01 kJ/min, P < 0.0001). The rate of protein synthesis averaged 207 +/- 13 g protein/day in the elderly and 230 +/- 13 g protein/day in the young group, whereas protein breakdown averaged 184 +/- 13 g protein/day in the elderly and 203 +/- 13 g protein/day in the young group (nonsignificant). When values were adjusted for body weight or FFM, they did not reveal any difference between the two groups. It is concluded that the reduced REE adjusted for body composition observed in elderly Gambian men is not explained by a decrease in protein turnover.

Effects of hyperglycemia on glucose metabolism before and after oral glucose ingestion in normal men.

The plasma glucose excursion may influence the metabolic responses after oral glucose ingestion. Although previous studies addressed the effects of hyperglycemia in conditions of hyperinsulinemia, it has not been evaluated whether the route of glucose administration (oral vs. intravenous) plays a role. Our aim was to determine the effects of moderately controlled hyperglycemia on glucose metabolism before and after oral glucose ingestion. Eight normal men underwent two oral glucose clamps at 6 and 10 mmol/l plasma glucose. Glucose turnover and cycling rates were measured by infusion of [2H7]glucose. The oral glucose load was labeled by D-[6,6-2H2]glucose to monitor exogenous glucose appearance, and respiratory exchanges were measured by indirect calorimetry. Sixty percent of the oral glucose load appeared in the systemic circulation during both the 6 and 10 mmol/l plasma glucose tests, although less endogenous glucose appeared during the 10 mmol/l tests before glucose ingestion (P &lt; 0.05). This inhibitory effect of hyperglycemia was not detectable after oral glucose ingestion, although glucose utilization was increased (+28%, P &lt; 0.05) due to increased nonoxidative glucose disposal [10 vs. 6 mmol/l: +20%, not significant (NS) before oral glucose ingestion; +40%, P &lt; 0.05 after oral glucose ingestion]. Glucose cycling rates were increased by hyperglycemia (+13% before oral glucose ingestion, P &lt; 0.001; +31% after oral glucose ingestion, P &lt; 0.05) and oral glucose ingestion during both the 6 (+10%, P &lt; 0.05) and 10 mmol/l (+26%, P &lt; 0.005) tests. A moderate hyperglycemia inhibits endogenous glucose production and contributes to glucose tolerance by enhancing nonoxidative glucose disposal. Hyperglycemia and oral glucose ingestion both stimulate glucose cycling.

Enteral versus parenteral nutrition: comparison of energy metabolism in healthy subjects.

Continuous respiratory exchange measurements were performed on 10 healthy young women for 1 h before, 3 h during, and 3 h after either parenteral (iv) or intragastric (ig) administration of a nutrient mixture (52% glucose, 18% amino acid, and 30% lipid energy) infused at twice the postabsorptive resting energy expenditure (REE). REE rose from 0.98 +/- 0.02 (iv) and 0.99 +/- 0.02 kcal/min (ig) postabsorptively to 1.13 +/- 0.03 (iv) and 1.13 +/- 0.02 kcal/min (ig), resulting in nutrient-induced thermogenesis of 10 +/- 0.6 and 9.3 +/- 0.9%, respectively, when related to the metabolizable energy. The respiratory quotient rose from preinfusion values of 0.81 +/- 0.02 (iv) and 0.80 +/- 0.01 (ig) to 0.86 +/- 0.01 (iv) and 0.85 +/- 0.01 (ig). After nutrient administration the respiratory quotient fell significantly to below the preinfusion values. Plasma glucose and insulin concentrations rose during nutrient administration but were higher during the intravenous route. It is concluded that, although the response time to intragastric administration was delayed, the thermic effects and overall substrate oxidations were comparable during intravenous or intragastric administration, albeit, at lower plasma glucose and insulin concentrations via the intragastric route.

Effects of infused amino acids on glucose production and utilization in healthy human subjects.

Amino acids have been reported to increase endogenous glucose production in normal human subjects during hyperinsulinemia: however, controversy exists as to whether insulin-mediated glucose disposal is inhibited under these conditions. The effect of an amino acid infusion on glucose oxidation rate has so far not been determined. Substrate oxidation rates, endogenous glucose production, and [13C]glucose synthesis from [13C]bicarbonate were measured in six normal human subjects during sequential infusions of exogenous glucose and exogenous glucose with (n = 5) or without (n = 5) exogenous amino acids. Amino acids increased endogenous glucose production by 84% and [13C]glucose synthesis by 235%. Glucose oxidation estimated from indirect calorimetry decreased slightly after amino acids, but glucose oxidation estimated from [13C]glucose-13CO2 data was increased by 14%. It is concluded that gluconeogenesis is the major pathway of amino acid degradation. During amino acid administration, indirect calorimetry underestimates the true rate of glucose oxidation, whereas glucose oxidation calculated from the 13C enrichment of expired CO2 during [U-13C]glucose infusion does not. A slight stimulation of glucose oxidation during amino acid infusion, concomitant with an increased plasma insulin concentration, indicates that amino acids do not inhibit glucose oxidation.

On the morphology of Laevapex vazi n. sp. from Brazil (Mollusca: Pulmonata: Basommatophora: Ancylidae)

A description of Laevapex vazi n. sp. based on 8 specimens collectec in Ourinhos, state of São Paulo, is presented. Shell thin, diaphanous, with a light brown periostracum and moderately elliptical opening. Apex not pointed, smooth, situated on the right posterior region of the shell, inclined to the right often reaching the edge of the shell or extending beyond it. Concentric lines clearly visible; radial striation not visible or when perceptible very thin, here and there. Ratios: shell width/shell lenght = 0,60 - 0,67 (mean = 0,63); shell height/shell length = 0,50 - 0,61 (mean = 0,55); shell height/shell width = 0,33 - 0,40 (mean = 0,35). Body of normal ancylid type; mantle pigmentation concentrated on the left side; three muscles are seen: a round posterior one on the left side, an elliptical muscle on the right anterior side and an almost almond-shaped one on the left anterior side. Tentacles with a medium core of black pigment. Pseudobranch two-lobed and folded, the dorsal lobe smaller than the vetral one. Ovotestis with 20 unbranched diverticula, around a short collecting canal. Ovispermiduct with an enlargement with several round outpocketings constituting the seminal vesicle. Carrefour as a round sac. Albumen gland almost cylindrical with several acinous diverticula. Elongated nidamental gland continous with the galndular wall of the uterus; uterus flattened and thin-walled. Spermathecal body almost rounded. Pear-shaped prostate without diverticula. Penial complex without flagellum but with well-developed ultra-penis and penis. Jaw horseshoe shaped. Radular forma 20.1.20; raquidian tooth quadricuspid, asymmetrical. The genus Laevapex Walker, 1903 is recorded for the first time in Brazil. It is easily distinguished from South American Gundlachia Pfeiffer, 1849 by its penial complex. Laevapex vazi is dedicated to Dr. Jorge Faria Vaz, from SUCEN-SP, who have been sent to me the specimens.

Art i església a la Mallorca del segle XVI a través de les visites pastorals del bisbe Joan Vic i Manrique (1573-1604)

Aquest treball de recerca del doctorand Bartomeu Martínez Oliver titulat Art i Església a la Mallorca del segle XVI a través de les visites pastorals del bisbe Joan Vic i Manrique (1573-1604) és innovador pel tema, però també per l’enfocament metodològic, ja que obre noves vies per conèixer millor l’art eclesiàstic, en el seu cas de Mallorca al tombant del segle XVII, mitjançant l’anàlisi rigorós de les visites pastorals del bisbe Joan Vic i Manrique conservades a l’arxiu diocesà de Mallorca. Bartomeu Martínez Oliver centra l’interés en la personalitat d’un prelat extraordinari que governà la diòcesi de mallorquina durant més de trenta anys. A més de l’enèrgica aplicació dels principis reformadors del Concili de Trento (1545-1563), aquest bisbe valencià (que gaudia d’una conspícua cultura, no debades era nét de Jeroni Vich i Vallterra, ambaixador de Ferran el Catòlic a Roma i important col•leccionista de pintura renaixentista) va ser l’introductor de noves devocions a l’illa, per exemple la Immaculada Concepció, i va afavorir els intercanvis artístics entre Mallorca i València. Finalment, dins la novetat del tema a Mallorca, cal dir que la investigació de Bartomeu Martínez connecta amb les investigacions sobre el pontificat immediatament anterior del bisbe Diego de Arnedo (1562-1572) i també, amb els treballs que s’han fet en altres diòcesis de l’Estat espanyol, i específicament a Catalunya. En aquest sentit, aquell treball de recerca ampliarà el coneixement real de l’aplicació conciliar que ha suscitat molts de tòpics dins la historiografia

Effects of infused fructose on endogenous glucose production, gluconeogenesis, and glycogen metabolism.

To determine the mechanisms that prevent an increase in gluconeogenesis from increasing hepatic glucose output, six healthy women were infused with [1-13C]fructose (22 mumol.kg-1.min-1), somatostatin, insulin, and glucagon. In control experiment, non-13C-enriched fructose was infused at the same rate without somatostatin, and [U-13C]glucose was infused to measure specifically plasma glucose oxidation. Endogenous glucose production (EGP, [6,6-2H]glucose), net carbohydrate oxidation (CHOox, indirect calorimetry), and fructose oxidation (13CO2) were measured. EGP rate did not increase after fructose infusion with (13.1 +/- 1.2 vs. 12.9 +/- 0.3 mumol.kg-1.min-1) and without (10.3 +/- 0.5 vs. 9.7 +/- 0.5 mumol.kg-1.min-1) somatostatin, despite the fact that gluconeogenesis increased. Nonoxidative fructose disposal, corresponding mainly to glycogen synthesis, was threefold net glycogen deposition, the latter calculated as fructose infusion minus CHOox (14.8 +/- 1.1 and 4.3 +/- 2.0 mumol.kg-1.min-1). It is concluded that 1) the mechanism by which EGP remains constant when gluconeogenesis from fructose increases is independent of changes in insulin and 2) simultaneous breakdown and synthesis of glycogen occurred during fructose infusion.

Interespecific competition between Peckia chrysostoma and Adiscochaeta ingens (Diptera: Sarcophagidae) larvae reared in laboratory

Groups of 10 and 20 first instar larvae of Peckia chrysostoma (Wiedemann, 1830) were combined in a proteic source media with groups of the same number of first instar larvae of Adiscochaeta ingens (Walker, 1849) under the environmental conditions of Rio de Janeiro, RJ, Brasil. P. chrysostoma and A. ingens obtained average competitive potentials of 94.0 ± 2.0% and 31.0 ± 5.0% respectively. In the second experiment, larvae of P. chrysostoma were introduced approximately 15 hr after the introduction of A. ingens larvae (whose majority had already passed to the second instar) in the media. The corresponding average competitive potential of P. chrysostoma (82.0 ± 2.0%) was decreased when compared to the first experiment, but still greater than that of A. ingens (64.5 ± 9.5%). The competitive potential of A. ingens, however, increased significatively, demonstrating the influence of its previous colonization in the media for achieving a higher viability. In both experiments the competitive potential of P. chrysostoma was greater and similar to observations cited in the literature. Control-groups of each species were observed, individually, for the comparison. The mean value obtained for P. chrysostoma was 94.0 ± 3.7% (0.0% [experiment 1] and only 12.8% [experiment 2] greater than the average competitive factor). For A. ingens the average was 86.0 ± 7.3% (64.0% [experiment 1] and 25.0% [experiment 2] greater than average competitive factor).

Strindberg a Barcelona (1903-1936)

Recepció del teatre d’August Strindberg (1849-1912) a Barcelona tant de la representació de les seves obres com de la publicació dels seus textos des de la darrera dècada del segle XIX fins a l’esclat de la Guerra Civil. El treball s’estructura en dues parts clarament diferenciades i desiguals quant a l’extensió. En la primera part, s’ofereix una aproximació sumària a l’obra de Strindberg en el marc del teatre europeu, a cavall del Naturalisme i la seva possible identificació com a precedent de l’Expressionisme sorgit a Alemanya en el període d’entreguerres. En aquest bloc es realitza també un recorregut per l’obra dramàtica de l’autor suec, tot destacant-ne algunes de les seves aportacions més significatives. El gruix de la investigació es concentra en la segona part sobre la recepció de Strindberg a Barcelona. Es tracta de plantejar-se si les obres de Strindberg van ser representades amb certa regularitat a la capital catalana entre finals del XIX i el primer terç de segle XX.

Neotropical planorbid snails with apertural lamellae: I. Biomphalaria helophila (Orbigny, 1835)

A definition of Biomphalaria helophila (Orbigny, 1835) is presented, based on examination of the shell and reproductive system of topotypic specimens and extended to a number of samples from other localities. The following nominal species and subspecies, collected from type localities, proved junior synonyms of B. helophila: Planorbis albicans Pfeiffer, 1839; Planorbis dentatus Gould, 1844; Planorbis dentiferus CB Adams, 1845; Planorbis dentiferus edentatus CB Adams, 1851; Planorbis dentiens Morelet, 1849; Planorbula dentiens edentula Fischer & Crosse, 1880; Planorbis stagnicola Morelet, 1851; and Tropicorbis shimeki FC Baker, 1945. B. helophila was also identified in samples from Costa Rica, Guatemala, Haiti, Dominican Republic, Puerto Rico and Barbados.

Whole body protein metabolism and resting energy expenditure in pregnant Gambian women.

Whole body protein metabolism and resting energy expenditure (REE) were measured at 11, 23, and 33 wk of pregnancy in nine pregnant (not malnourished) Gambian women and in eight matched nonpregnant nonlactating (NPNL) matched controls. Rates of whole body nitrogen flux, protein synthesis, and protein breakdown were determined in the fed state from the level of isotope enrichment of urinary urea and ammonia during a period of 9 h after a single oral dose of [15N]glycine. At regular intervals, REE was measured by indirect calorimetry (hood system). Based on the arithmetic end-product average of values obtained with urea and ammonia, a significant increase in whole body protein synthesis was observed during the second trimester (5.8 +/- 0.4 g.kg-1.day-1) relative to values obtained both for the NPNL controls (4.5 +/- 0.3 g.kg-1.day-1) and those during the first trimester (4.7 +/- 0.3 g.kg-1.day-1). There was a significant rise in REE during the third trimester both in the preprandial and postprandial states. No correlation was found between REE after meal ingestion and the rate of whole body protein synthesis.

Resultados a largo plazo en el tratamiento del osteosarcoma: experiencia de 20 años

Hem analitzat de manera retrospectiva una sèrie de 58 pacients diagnosticats d’un osteosarcoma no metastàsic a l’Hospital Universitari La Fe de València entre els anys 1985 i 2005. La supervivència global obtinguda als 5 i 10 anys va ser del 57 i del 50 % respectivament. Hem identificat com a factors pronòstic independents la grandària tumoral i la localització axial. Un 50% dels pacients van morir com a conseqüència d’una recidiva sistèmica malgrat haver estat tractats, la majoria, amb cirurgia amb conservació de membre i quimioteràpia tant pre com postoperatòria. El rescat quirúrgic de la recidiva proporciona supervivències prolongades d’una manera significativa.

Estudio descriptivo del Síndrome de Distrés Respiratorio del Adulto en el Paciente Politraumatizado.

La síndrome de distrés respiratori agut es caracteritza per hipoxemia, infiltrats bilaterals en la radiografia de tórax en absència de signes d'insuficiència cardíaca. Les teràpies destinades al tractament no han tingut resultats esperançadors per la impossibilitat de detectar precoçment la població en risc. El nostre objectiu és fer una anàlisi descriptiva i prospectiu dels pacients politraumatizats que van ingressar en la Fe de València durant 2009. Analitzant diverses variables: APACHE, pH, Làctic, etc; mesurant-les a l'ingrés, a les 12, 24 i 48h. Concloent que els únics factors amb significació estadística van ser l'A. Làctic i el pH a les 12h
