CARACTERÍSTICAS DE CARCAÇA E BIOMETRIA TESTICULAR DE MACHOS BOVINOS SUPERJOVENS NÃO CASTRADOS DE DIFERENTES GRUPOS GENÉTICOS
The objective of this work was to evaluate carcass characteristics and testicular biometry of non-castrated Hereford (H), 3/4H 1/4 Nellore (N), 5/8H 3/8N and 3/4 Charolais (C) 1/4 N males, slaughtered at fourteen months of age. No statistical difference occurred among genetic groups for final and carcasses weights and dressing percentages. The sawcut yield was higher in 3/4CN than other genotypes. Ribcut yield was higher for 5/8HN in relation to 3/4HN and 3/4CN. Longissimus dorsi area was higher for 3/4CN (71.5 cm2) animals in relation to Hereford (63.5 cm2). Hereford animals also showed lower leg length than all other groups. The 3/4CN males showed lower (2.6 mm) subcutaneous fat thickness than Hereford (5.0 mm), 5/8HN (4.1 mm) and 3/4HN (4.1 mm) ones. In conclusion, all genetic groups get compatible carcass characteristics for young cattle market. Besides, muscular development related characteristics, such as conformation and sawcut yield, were better in Charolais crossbred genotype, while characteristics related to fat deposition, such as fat thickness and ribcut yield, were better in Hereford and crossbred Hereford genotypes
Cinema, autoritarismo e política de meios na Argentina: o Festival de Mar del Plata de 1968
Objetivo/contexto: El artículo analiza el proceso de organización del IX Festival Internacional de Cine de Mar del Plata de 1968 y su desarrollo. Se reconstruyen los objetivos que la dictadura del general Juan Carlos Onganía persiguió con la realización de este Festival, hasta entonces organizado por entidades privadas, y también se elaboran las tensiones generadas dentro de la alianza del Gobierno y con grupos del campo cinematográfico. Originalidad: Hasta el momento, la historiografía ha hecho énfasis en la fuerte represión cultural de la dictadura de Onganía. Sin negar esta perspectiva, el análisis de esta experiencia de apertura selectiva aporta nuevas ideas para pensar las políticas culturales y de medios de las dictaduras como estrategia de construcción de consenso interno y legitimación del gobierno en el ámbito de las relaciones internacionales, así como su reverso, el campo cultural como territorio de disputas políticas en el marco de gobiernos autoritarios. Metodología: La investigación fue realizada principalmente a partir del análisis de múltiples publicaciones impresas de la época. Conclusiones: El trabajo propone entender esta experiencia cultural como un proceso de apertura selectivo y restringido, orientado a mejorar la imagen en el exterior del Gobierno a través de la cinematografía. Sin embargo, se trató de una experiencia fallida, porque desde el momento en que se desplegó ese objetivo el Festival se politizó y se presentó como un terreno de disputas entre distintas facciones dentro del Gobierno y del Gobierno con el mundo del cine.Objective/context: The article analyzes the organizational process and execution of the IX Mar del Plata International Film Festival of 1968. It outlines the objectives that General Juan Carlos Onganía’s dictatorship pursued with this festival, which had, until 1968, been organized by private entities. The tensions that arose between the government alliance and cinematographic groups is also discussed. Originality: Until now, historiography has emphasized the strong cultural repression of the Onganía dictatorship. Without denying this perspective, the analysis of this selective opening experience at the film festival brings to the fore new perspectives on how dictatorships used cultural and media policies as an internal consensus building strategy and as a tactic to legitimize the government internationally. Conversely, the cultural arena is seen as a territory for political disputes within the framework of authoritarian governments. Methodology: The research was conducted mainly from the analysis of multiple printed publications of the time. Conclusions: This paper proposes understanding this cultural experience as a process aimed at improving the image of the government abroad through cinematography. However, this attempt by the dictatorship failed because, from the moment that the strategy was launched, the festival became politicized and it was transformed into a terrain of disputes between different factions within the government as well as between the government and the world of cinema.Objetivo/contexto: O artigo analisa o processo de organização do IX Festival Internacional de Cinema de Mar del Plata de 1968 e seu desenvolvimento.

Diversity and ethics in trauma and acute care surgery teams: results from an international survey
Background Investigating the context of trauma and acute care surgery, the article aims at understanding the factors that can enhance some ethical aspects, namely the importance of patient consent, the perceptiveness of the ethical role of the trauma leader, and the perceived importance of ethics as an educational subject. Methods The article employs an international questionnaire promoted by the World Society of Emergency Surgery. Results Through the analysis of 402 fully filled questionnaires by surgeons from 72 different countries, the three main ethical topics are investigated through the lens of gender, membership of an academic or non-academic institution, an official trauma team, and a diverse group. In general terms, results highlight greater attention paid by surgeons belonging to academic institutions, official trauma teams, and diverse groups. Conclusions Our results underline that some organizational factors (e.g., the fact that the team belongs to a university context or is more diverse) might lead to the development of a higher sensibility on ethical matters. Embracing cultural diversity forces trauma teams to deal with different mindsets. Organizations should, therefore, consider those elements in defining their organizational procedures. Level of evidence Trauma and acute care teams work under tremendous pressure and complex circumstances, with their members needing to make ethical decisions quickly. The international survey allowed to shed light on how team assembly decisions might represent an opportunity to coordinate team member actions and increase performance
30-50-70 : conformación, crisis y renovación del cine industrial argentino y latinoamericano
Cátedra de Historia del cine latinoamericano y argentino. El volumen es el resultado de un trabajo realizado por los docentes e investigadores de esta cátedra, junto a especialistas invitados de otros ámbitos universitarios. Nuestro enfoque propone revisitar la historia del cine latinoamericano, con énfasis en el cine argentino, focalizando en las décadas de los 30, 50 y 70. Mientras que en los 30 observaremos las bases de la constitución del modelo industrial, en los 50 analizaremos la paulatina crisis y cuestionamiento del mismo sistema. Llegaremos entonces a los 70, cuando en el resurgimiento del cine industrial confluyan las políticas de autor y las preocupaciones del cine militante de la década previa, en una síntesis que retoma las formas populares, genéricas y comerciales del espectáculo.Libros de Cátedr
Pest control treatments with phosphine and controlled atmospheres in silo bags with different airtightness conditions
La tecnología de bolsas de silo ha sido ampliamente utilizada en Argentina para almacenar granos (por ejemplo, trigo, maíz, cebada, girasol y soja, entre otros) desde mediados de los años noventa. Bolsa de silo son ampliamente considerados
Hermético en el que la fumigación con PH3 se implementa con frecuencia para el control de plagas. Sin embargo,no hay suficiente información sobre la posible hermeticidad de las bolsas de silo y cómo podría afectar el desempeño de los tratamientos de fumigación y atmósfera controlada. En este estudio, una prueba de decaimiento de presión (PDT) para caracterizar el nivel de hermeticidad de las bolsas de silo establecidas siguiendo diversos procedimientosThe silo bag technology has been extensively used in Argentina for storing grains (e.g. wheat, corn, barley, sunflower and soybean among others) since the mid-1990s. Silo bag are widely considered a hermetic storage system in which PH3 fumigation is frequently implemented for pest control. However, there is insufficient information regarding the potential airtightness of silo bags and how it could affect the performance of fumigation and controlled atmosphere treatments. In this study, a pressure decay test (PDT) was implemented to characterize airtightness level of silo bags set up following various procedures. PH3 fumigation treatments with different dosages and hermeticity levels were conducted, and fumigant concentration was monitored. Controlled atmosphere treatments with carbon dioxide were also implemented in silo bags with different hermeticity levels. Results showed that less than half of the bags tested in the field had a PDT indicated for fumigation (90 s), and that when a bag without thermo sealing was used for fumigation, this treatment failed. However, it was demonstrated that with simple and inexpensive practices silo bags can achieve high enough airtightness conditions to implement successful PH3 fumigation (5 days above 200 ppm with a dosage of 1 g of PH3/m3) and even controlled atmosphere treatments (more than 18 days with CO2 concentration above 70%). This study shows that silo bags could be used as a cost competitive hermetic storage technology for performing controlled atmosphere treatments.EEA BalcarceFil: Carpaneto, Barbara Bettina.

Long-term safety and efficacy of subcutaneous pasireotide in patients with Cushing\u27s disease: interim results from a long-term real-world evidence study.
PURPOSE: Clinical trials have demonstrated the favorable efficacy/safety profile of pasireotide in patients with Cushing\u27s disease (CD). We report interim long-term results of an ongoing real-world evidence study of subcutaneous pasireotide in patients with CD.
METHODS: Adults with CD receiving pasireotide, initiated before (prior-use) or at study entry (new-use), were monitored for ≤ 3 years during a multicenter observational study ( http://clinicaltrials.gov identifier NCT02310269). Primary objective was to assess long-term safety of pasireotide alone or with other CD therapies.
RESULTS: At the time of this interim analysis, 127 patients had received pasireotide (new-use, n = 31; prior-use, n = 96). Eight patients had completed the 3-year observation period, 53 were ongoing, and 66 had discontinued. Among 31 new-use and 92 prior-use patients with ≥ 1 safety assessment, respectively: 24 (77%) and 37 (40%) had drug-related adverse events (AEs); 7 (23%) and 10 (11%) had serious drug-related AEs. Most common drug-related AEs were nausea (14%), hyperglycemia (11%) and diarrhea (11%); these were more frequently reported in new users and mostly of mild-to-moderate severity. 14 (45%) new-use and 15 (16%) prior-use patients experienced hyperglycemia-related AEs. Mean urinary free cortisol (mUFC) was within normal range at baseline and months 1, 12 and 24, respectively, in: 1/16 (6%), 9/18 (50%), 1/3 (33%) and 0/0 new users; 28/43 (65%), 15/27 (56%), 27/33 (82%) and 12/19 (63%) prior users.
CONCLUSIONS: Pasireotide is well tolerated and provides sustained reductions in mUFC during real-world treatment of CD. The lower rate of hyperglycemia-related AEs in prior users suggests that hyperglycemia tends not to deteriorate if effectively managed soon after onset.

Generalized biomass equations for Stone pine (Pinus pinea L.) across the Mediterranean basin
Accurate estimates of tree biomass are strongly required for forest carbon budget estimates and to understand ecosystem dynamics for a sustainable management. Existing biomass equations for Mediterranean species are scarce, stand- and site-specific and therefore are not suitable for large scale application.
In this study, biomass allometric equations were developed for stone pine (Pinus pinea L.), a Mediterranean tree species with relevant ecologic and economic interest. A dataset of 283 harvested trees was compiled with above- and belowground biomass from 16 sites in three countries (Italy, Spain, Portugal) representative of the species’ geographical Mediterranean distribution. A preliminary approach comparing the ordinary least squares method and the mixed model approach was performed in order to evaluate the most appropriate method for nested data in the absence of calibration data. To quantify the sources of error associated with applying biomass equations beyond the geographical range of the data used to develop them, a residual analysis was conducted.
The allometric analysis showed low intra-specific variability in aboveground biomass relationships, which was relatively insensitive to the stand and site conditions. Significant differences were found for the crown components (needles and branches), which may be attributed to local geographical adaptation, site conditions and stand management. The root biomass was highly correlated with diameter at breast height irrespective of the geographical origin. Biased estimates were found when using site-specific equations outside the geographical range from where they were developed.
The new biomass equations improved the accuracy of biomass estimates, particularly for the aboveground components of higher dimension trees and for the root component, being highly suitable for use in regional and national biomass forest calculations. It is, up to the present, the most complete database of harvested stone pine trees worldwide
