    La producción de carne aviar en sistemas de manejo semi-intensivo es una modalidad ecológica que contempla aspectos vinculados con el bienestar animal. El pollo Campero es un ave con menor velocidad de crecimiento que los parrilleros comerciales, destinado a la producción de carne. El esquema tradicional de alimentación incluye la utilización de tres tipos de alimentos especialmente formulados a tal fin (iniciador, crecimiento y terminador), lo cual introduce complicaciones en el manejo, particularmente en lo referido a la disponibilidad del alimento “crecimiento” para los pequeños productores. Una alternativa que facilitaría el manejo de estas aves es un esquema basado en sólo dos tipos de alimentos: iniciador y terminador. El objetivo de este trabajo fue evaluar el efecto del cambio del manejo tradicional de la alimentación por uno alternativo reemplazando el alimento “crecimiento” por una mezcla de iniciador y terminador, en dos genotipos de pollo Campero con diferente velocidad de crecimiento: el híbrido experimental de tres vías Campero Casilda y el híbrido simple Campero INTA. La evidencia indicó que el cambio en el manejo de la alimentación no afectó el crecimiento, la relación de conversión ni los caracteres a la faena. Ambos grupos genéticos se comportaron de manera equivalente, pudiendo obviarse la inclusión de la categoría “crecimiento” si se la reemplaza por una mezcla de iniciador y terminador.Poultry meat production in semi-intensive management systems is an ecological modality that takes into account aspects related to animal welfare. Campero chicken is a bird with a slower growth rate than commercial broilers destined to the production of meat in this type of systems. The traditional feeding scheme includes the use of three types of food specially formulated for this purpose (starter, grower and finisher) which introduces management complications, particularly in relation to the availability of grower food for small producers. An alternative that would facilitate feeding management is a scheme based on only two types of food: starter and finisher. The aim of this work was to evaluate the effect of changing the traditional feeding scheme by an alternative one, replacing grower food with a mix of starter and finisher, in two genotypes of chicken with a different growth rate: the experimental three-way cross Campero Casilda and the two-way cross Campero INTA. The evidence indicates that the proposed change in the traditional feeding management does not affect body growth, feed conversion ratio and productive traits at slaughter, and that both genetic groups behave similarly, when grower diet is replaced by a mix of starter and finisher.EEA PergaminoFil: Dottavio, Ana M.

    BACKGROUND: Bovine herpesvirus type 1 (BoHV-1) is the causative agent of respiratory and genital tract infections; causing a high economic loss in all continents. Use of marker vaccines in IBR eradication programs is widely accepted since it allows for protection of the animals against the disease while adding the possibility of differentiating vaccinated from infected animals.The aim of the present study was the development and evaluation of safety and efficacy of a glycoprotein E-deleted (gE-) BoHV-1 marker vaccine strain (BoHV-1ΔgEβgal) generated by homologous recombination, replacing the viral gE gene with the β-galactosidase (βgal) gene. RESULTS: In vitro growth kinetics of the BoHV-1ΔgEβgal virus was similar to BoHV-1 LA. The immune response triggered by the new recombinant strain in cattle was characterized both as live attenuated vaccine (LAV) and as an inactivated vaccine. BoHV-1ΔgEβgal was highly immunogenic in both formulations, inducing specific humoral and cellular immune responses. Antibody titers found in animals vaccinated with the inactivated vaccine based on BoHV-1ΔgEβgal was similar to the titers found for the control vaccine (BoHV-1 LA). In the same way, titers of inactivated vaccine groups were significantly higher than any of the LAV immunized groups, independently of the inoculation route (p < 0.001). Levels of IFN-γ were significantly higher (p < 0.001) in those animals that received the LAV compared to those that received the inactivated vaccine. BoHV-1ΔgEβgal exhibited an evident attenuation when administered as a LAV; no virus was detected in nasal secretions of vaccinated or sentinel animals during the post-vaccination period. BoHV-1ΔgEβgal, when used in either formulation, elicited an efficient immune response that protected animals against challenge with virulent wild-type BoHV-1. Also, the deletion of the gE gene served as an immunological marker to differentiate vaccinated animals from infected animals. All animals vaccinated with the BoHV-1ΔgE βgal strain were protected against disease after challenge and shed significantly less virus than control calves, regardless of the route and formulation they were inoculated. CONCLUSIONS: Based on its attenuation, immunogenicity and protective effect after challenge, BoHV-1ΔgEβgal virus is an efficient and safe vaccine candidate when used either as inactivated or as live attenuated forms.Fil: Romera, Sonia.

    Relapse of unusual localization of classic seminoma with post-chemotherapy transformation

    Get PDF
    Germ cell tumor is the most common cancer among males in the 20–39 year-old age range, representing 21% of invasive cancer diagnose. The vast majority of testicular tumors in this age range are germ cell tumors. There are two types of malignant tumors, the pure seminoma cell and non-seminomatous germinal cell tumors (NGCT). We present the case of a patient who underwent a testicular tumor surgery, classic seminoma stage I, receiving two cycles of adjuvant carboplatin chemotherapy. During the follow up, an elevation on the alpha-fetoprotein level was observed, thus the final diagnosis was adenopatic recurrence of the Yolk Sac tumor.-----------------------------------------------------------------Cite this article as: Urena MD, Legeren M, Galvez F, Villaescusa A, Aparicio J, Jurado JM, Blancas I, Sanchez MJ, Romera AL, Martinez AP, Quiñonez E, Dulcey I, Puche JL.

    The relevance of personality traits in impulsivity-related disorders: from substance use disorders and gambling disorder to bulimia nervosa

    Get PDF
    Background and aims: the main aim of this study was to analyze and describe the clinical characteristics and shared personality traits in different impulsivity-compulsivity spectrum disorders: substance use disorders (SUD), gambling disorder (GD), and bulimia nervosa (BN). The specific aims were to compare personality differences among individuals with pure SUD, BN with and without SUD, and GD with and without SUD. In addition, we assessed the differential predictive capacity of clinical and personality variables in relation to diagnostic subtype. Methods: the sample comprised 998 subjects diagnosed according to DSM-IV-TR criteria: 101 patients were diagnosed with SUD, 482 with GD, 359 with BN, 11 with GD + SUD, and 45 patients with BN + SUD. Various assessment instruments were administered, as well as other clinical measures, to evaluate their predictive capacity. Results: marked differences in personality traits were observed between groups. Novelty seeking, harm avoidance, self-directedness, cooperation, and self-transcendence best differentiated the groups. Notably, novelty seeking was significantly higher in the two dual pathology subgroups. Patients with dual pathology showed the most dysfunctional personality profiles. Discussion and conclusion: our results indicate the existence of shared dysfunctional personality traits among the groups studied, especially in novelty seeking and self-directedness

    Background and aims: recent technological developments have brought about notable changes in the way people gamble. The widespread use of mobile Internet devices and gambling websites has led to a significant leap in the number of people who recreationally gamble. However, for some, gambling can turn into a psychiatric disorder resembling substance addiction. At present, there is a shortage of studies examining differences between adults with gambling disorder (GD) who exclusively make sports bets online, GD patients that are non-sports Internet gamblers, and offline gamblers. Therefore, this study was undertaken to determine the differences between these three groups, considering sociodemographic, personality, and clinical characteristics. Methods: the sample consisted of 2,743 treatment-seeking male patients from the Pathological Gambling Unit at a university hospital. All patients met DSM-5 criteria for GD. Results: we found that gamblers who exclusively engaged in non-sports Internet gambling activities were younger than offline gamblers and online sports gamblers. Non-sports Internet gamblers were also more likely to have greater levels of debt compared with offline gamblers. In terms of personality characteristics, our sample displayed low levels of self-directedness and cooperativeness and high levels of novelty seeking. In addition, online sports gamblers obtained higher scores in persistence than non-sports Internet gamblers and offline gamblers. Discussion and conclusion: although differences if terms of gambling severity were not identified between groups, GD patients who exclusively bet online appear to possess distinct personality characteristics and higher debt levels compared with offline gamblers

    Una encuesta transversal ad hoc se llevó a cabo en veintitrés majadas caprinas correspondientes a unidades productivas (UP) familiares extensivos (UPF, n=19) y semiintensivas (UPL, n=4) dedicadas a la producción de leche en los valles templados de Salta y Jujuy con el objetivo de describir la presencia de enfermedades en sus majadas. Se recabaron datos del manejo general y sanitario en particular. Se procesaron sueros para el diagnóstico de brucelosis por las pruebas tamiz del antígeno bufferado en placa y confirmadas por polarización fluorescente. Paraparatuberculosis, herpesvirus caprino tipo 1 (CaHV-1), neosporosis y toxoplasmosis se utilizó ELISA indirecto y para leptospirosis microaglutinación. Se determinaron los valores de Cu2+, Zn2+, Mg2+ y Ca2+ sérico por espectrofotometría de absorción atómica. En heces, se realizó el recuento de huevos de helmintos por gramo (hpg) y la diferenciación de géneros por coprocultivo. Las UP muestreadas crían en promedio 48,4 ±30,7 (UPF) y 221,3 ±78,7 (UPL) caprinos respectivamente, sin contar los cabritos menores a los 45 días de edad. La cría de las UPF fue extensiva con encierre nocturno y la alimentación sobre pastizal natural mientras que las UPL combinaban pasturas bajo riego con suplementación en base de concentrados. Existen dos períodos de pariciones al año; el principal donde pare casi la totalidad de la majada se localiza desde fines de marzo a fines de septiembre y el segundo período donde pare una menor proporción de cabras se ubica desde septiembre a diciembre. El 94,7% de los productores desparasitaba en forma rutinaria toda la majada y el 75% trataban los piojos. En un 41,2% de las UP se inyectaba mineralizantes-vitamínicos a toda la majada y en solo un 15% vacunaba contra enfermedades Clostridiales. El promedio de la tasa de mortalidad anual fue del 20,1±9,8% y 7,8±3,0% respectivamente en UPF y UPL. En el 100% de las UPF se registró la ocurrencia de abortos, y de estos el 25% presentó retención de placenta. El promedio intramajada de abortos comunicados fue del 14,5 ±11,6%. El 58,8% de las UP declaró tener casos de ectima contagioso. Se registraron un 26,7% cuadros de muertes agudas probablemente por infecciones Clostridiales. En el 93,3% de las UPF se registraron problemas de mastitis. El porcentaje de UP con seroprevalencia positiva a brucelosis, leptospirosis, paratuberculosis, toxoplasmosis, neosporosis y CpHV-1 fue respectivamente de 0%, 0%, 0%, 73,3%, 40% y 87,5%. Los promedios de los hpg de invierno – primavera y los de verano-otoño fueron respectivamente de 965 y 2859 hpg, con Haemonchus y Trichostrongylus y en menor medida Teladorsagia como nematodes predominantes. En el 31,6% de las UP se diagnosticó Fasciolosis. El 66,7% de las UP describió la presencia, a la faena, de quistes hidatídicos. En un 58% de las majadas se describió bocio. Los promedios por UP de cobre, zinc, magnesio y calcio séricos fueron respectivamente 0,59±0,10 ppm, 0,67±0,05 ppm, 2,30±0,29mg/dl y 8,42±1,92 mg/dl. Sin embargo, para el cobre y el calcio los valores promedios difieren (p<0,05) entre las UPF (0,66±0,08 ppm y 9,36 ±1,85 mg/dl) y las UPL (0,54±0,06 ppm y 7,02±0,76 mg/dl). Un 63,6% de las UP dijo tener intoxicación con cegadera (Heterophyllaea pustulata) y de muertes (50%) en animales jóvenes atribuidas al romerillo (Baccharis coridifolia) y en menor medida a la hediondilla (Cestrum parqui). Un 58,8% de los propietarios declararon tener problemas de pérdidas de animales principalmente por pumas. Estos primeros resultados muestran la importancia de llevar a cabo estudios más específicos respecto de la salud de las majadas para incrementar la producción y el bienestar general de las familias productoras.A cross-sectional survey was performed in 23 goat flocks (UP) of family extensive farming units (UPF) and semi-intensive farming units (UPL) from the temperate valleys of Jujuy and Salta provinces, with the aim of describing disease occurrence in goat flocks. Farmers were subjected to an ad hoc survey to gather data on general management and specific health issues. Sera were processed to diagnose brucellosis using the BPA screening test and positive sera were confirmed by FPA test. Paratuberculosis, caprine herpesvirus 1, toxoplasmosis and neosporosis were tested by indirect ELISA, and leptospirosis by microagglutination test. Serum Cu2+, Zn2+, Mg2+ and Ca2+ were determined by atomic absorption spectrophotometer. Fecal samples were taken for eggs counts per gram of feaces (epg) and identifying genera by coproculture. UP had on average 48,4 ±30,7 (UPF) y 221,3 ±78,7 (UPL) goats (not including kids). UPF animals are extensively bred, with nocturnal enclosure, and flock feeding is based on grazing the hills and UPL combined pastures under irrigation with concentrate-based supplementation. Kidding is concentrated in two periods: from late March to late September, when almost all the flock kids, and a second minor kid period that was from September to December. Farmers (94,7%) routinely treat all the flock against parasites and the 71,8% treat against lice. The 41,2% of UP provide all the flock with mineral-vitamin mixtures and only the 15, % vaccinated against clostridium diseases. Mean annual mortality rate per flock was 20,1±9,8% and 7,8±3,0% respectively for UPF and UPL. Abortions were recorded in 100% of the UP, 25% with retained placenta. Mean within-flock reported abortions were 14,5 ±11,6%. Contagious echtyma (orf) was detected in 58,8% of the UP and acute deaths probably due to clostridial infections were recorded in 26,7% of the UP. Mastitis-associated problems were recorded in 93,3% of UP. Positive seroprevalence of brucellosis, leptospirosis, paratuberculosis, toxoplasmosis, neosporosis and CpHV-1, in UP was 0%, 25%, 50%, 42,8%, 88,8%, 85,7%, 12,5% and 0% respectively. Mean epg were 965 and 2859 for winter-spring and summer-autumn respectively, with Haemonchus and Trichostrongylus and secondly Teladorsagia being the prevailing nematodes. Fasciola infections were recorded in 31,6% of the UP. The presence of hydatid cysts in slaughtered animals were indicated by 66,7% of UP. Signs of goiter were described in 58% of the flocks. Mean serum cooper, zinc, magnesium and calcium per UP were 0,59±0,10 ppm, 0,67±0,05 ppm, 2,30±0,29mg/dl and 8,42±1,92 mg/dl respectively. However cooper and calcium was different (p<0,05) between UPF (0,66±0,08 ppm and 9,36±1,85 mg/dl) and UPL (0,54±0,06 ppm and 7,02±0,76 mg/dl). A 63,6% of the UP reported cases of intoxication by cegadera (Heterophyllaea pustulata) and death (50%) were reported and attributed by farmers to the ingestion of romerillo (Baccharis coridifolia) and secondly of hediondilla (Cestrum parqui) by young animals. Some farmers (58.8%) indicated loss of animals mostly due to the attack by pumas. These first results regarding show the importance of conducting specific studies about the health of flocks in order to increase competitiveness in goat production and the welfare of farming families.Fil: Suarez, Víctor Humberto.

    The Marboré Symphony: music for the deglaciation and Holocene in the central Pyrenees

    Get PDF
    20th Congress of the International Union for Quaternary Research (INQUA), Dublín, 2019Geological sequences have been used as the main basis for musical pieces both as inspiration for musicians and as raw materials (geochemical data, stratigraphic logs, cycles and frequencies) for compositions produced by computer programs. Telling our stories of Quaternary changes with music presents an opportunity to reach a wider audience and to integrate art and science. Here we present an example of how to compose music from Quaternary lake sequences and illustrate in a new way the main changes in the Pyrenean landscapes since deglaciation. The creation of this music was undertaken within the framework of the REPLIM project, an INTERREG- POCTEFA – project aimed to create a network of climate change observatories on lakes and wetlands in the Pyrenees. Based on the sediment sequence from Marboré Lake (42°41′44.27″N, 0° 2′24.07″E, 2612 m a.s.l), we have selected lithological, compositional and pollen data (Leunda et al, 2017; Oliva et al., 2018) to represent the main changes in the lake and the region during the last 15000 years. To transform the geological data into musical notes, we have used a similar approach than in previous experiences (Simon et al, 2015) but in this case, notes were assigned to compositional range intervals and the tempos were defined using sediment accumulation rates. Different melodies and instruments were assigned at each data set: TOC and Br/Ti as lake bioproductivity, selected pollen data for vegetation dynamics in the valleys, Si/Ti as sediment influx and Pb/Ti as anthropogenic impact. An electronic version of the Marbore Symphony was created by computer software based on the raw data. The music group O’Carolan (http://www.ocarolanfolk.com) transformed the electronic version into a six minutes long acoustic version. The Symphony premiered in the town of Bielsa on December 14th, 2018. The Marboré music project has served to increase citizenship awareness about climate change in the Pyrenees and provided a new tool to better communicate past and future changes in the landscapesInstituto Pirenaico de Ecología, EspañaUniversidad de Zaragoza, EspañaGrupo O´Carolan, EspañaInstituto Geológico y Minero de España, EspañaUniversidad Autonoma de Madrid, EspañaUniversidad del Pais Vasco, Españ
