Efecto de una restricción alimenticia después del destete sobre la mortalidad y los rendimientos productivos de conejos en cebo

En este trabajo se ha estudiado el efecto de una restricción alimenticia moderada 15 y gradual después del destete (alrededor de 35 d de edad) sobre los rendimientos 16 productivos y la eficiencia alimenticia global del cebo. La restricción consistió en 17 suministrar una cantidad limitada de alimento (80, 100 y 120 g/d) en las tres semanas 18 siguientes al destete. Se han realizado seis ensayos, con 480 animales cada uno, 19 utilizando seis piensos comerciales que diferían en el tipo de medicación. En estos 20 ensayos se controlaron los parámetros de crecimiento, eficacia alimenticia global y 21 mortalidad durante el periodo de restricción y en el conjunto del cebo (destete a 63-67 d 22 de edad). El número de ooquistes y de Clostridium perfringens en heces duras fue 23 también evaluado en cada tratamiento. En ninguno de los ensayos se detectaron 24 problemas de elevada mortalidad causada por ERE. En estas condiciones, la mortalidad 25 de los gazapos restringidos se redujo un 33% (P=0,02) en el periodo de restricción y 26 tendió a disminuir en el conjunto del periodo de cebo. Los resultados obtenidos 27 muestran además que una restricción alimenticia moderada mejora en un 4% (Pmenor que0,001) 28 la eficiencia alimenticia global del cebo, sin afectar al peso total de animales enviado a 29 matadero. Además, la adopción de medidas que disminuyan la proliferación de 30 coccidios y C. perfringens en el contenido digestivo pueden resultar útiles para reducir 31 la mortalidad de conejos durante el ceb

Theatre cartographies in Spain: interpretation essay

[Resumen] Descubrir la ciudad en el teatro y el teatro en la ciudad a partir de la observación del mapa es el objetivo principal de este trabajo. A lo largo de la historia, la relación del teatro, de los teatros, y en sentido amplio de los espacios escénicos con la ciudad, ha adoptado formas diversas que una cartografía puede reflejar y ayudar a interpretar. Este artículo se centra en el estudio del papel de los edificios dedicados a las artes escénicas en las transformaciones de las ciudades de España. Nuestro enfoque abre un amplio panorama en el que se integran la ciudad, la arquitectura y el teatro, y en el que se observa con un grado de aproximación diverso el dónde, el qué, el cómo y el cuándo del hecho teatral. El espacio y el tiempo constituyen el trasfondo de nuestro análisis.[Abstract] Discovering the city in the theatre and the theatre in the city from the observation of the urban map is the main objective of this work. Throughout history, the relationship of the theatre, of the theatres, and in a broad sense of the scenic spaces with the city, has taken various forms that a cartography can reflect and help to interpret. This article focuses on the study of the role of the buildings dedicated to the performing arts in the transformations of the Spanish cities. Our approach opens up a wide panorama in which the city, architecture and theatre are integrated, and in which the where, what, how and when of the theatrical event are observed with a different degree of approximation. Space and Time constitute the background of our analysis

Golden Standard: a complete standard, portable, and interoperative MoClo tool for model and non-model proteobacteria

16 p.-8 fig.-1 tab.-1 graph.abst.Modular cloning has become a benchmark technology in synthetic biology. However, a notable disparity exists between its remarkable development and the need for standardization to facilitate seamless interoperability among systems. The field is thus impeded by an overwhelming proliferation of organism-specific systems that frequently lack compatibility. To overcome these issues, we present Golden Standard (GS), a Type IIS assembly method underpinned by the Standard European Vector Architecture. GS unlocks modular cloning applications for most bacteria, and delivers combinatorial multi-part assembly to create genetic circuits of up to twenty transcription units (TUs). Reliance on MoClo syntax renders GS fully compatible with many existing tools and it sets the path towards efficient reusability of available part libraries and assembled TUs. GS was validated in terms of DNA assembly, portability, interoperability and phenotype engineering in α-, β-, γ- and δ-proteobacteria. Furthermore, we provide a computational pipeline for parts characterization that was used to assess the performance of GS parts. To promote community-driven development of GS, we provide a dedicated web-portal including a repository of parts, vectors, and Wizard and Setup tools that guide users in designing constructs. Overall, GS establishes an open, standardized framework propelling the progress of synthetic biology as a whole.European Union's Horizon 2020 research and innovation program [814650 (Synbio4Flav), 633962 (P4SB), 814418 (SinFonia), 870294 (MixUp)]; Spanish Ministry of Science and Innovation for the RobExplode project PID2019‐108458RB‐I00 [AEI /10.13039/501100011033], BIO2017-83448-R and PID2020-112766RB-C21, and CSIC’s Interdisciplinary Platform for Sustainable Plastics towards a Circular Economy+ (PTI-SusPlast+); A.G.L. was funded by ‘Fondo Social Europeo’ and ‘Iniciativa de Empleo Juvenil (YEI)’ [PEJ-2020-AI/BIO-18028] and S.S. by a FPU (Ayuda para la formación de profesorado universitario) fellowship [FPU17/03978] from the Spanish Ministry of Universities.

SEVA 4.0: an update of the Standard European Vector Architecture database for advanced analysis and programming of bacterial phenotypes

10 Pág.The SEVA platform (https://seva-plasmids.com) was launched one decade ago, both as a database (DB) and as a physical repository of plasmid vectors for genetic analysis and engineering of Gram-negative bacteria with a structure and nomenclature that follows a strict, fixed architecture of functional DNA segments. While the current update keeps the basic features of earlier versions, the platform has been upgraded not only with many more ready-to-use plasmids but also with features that expand the range of target species, harmonize DNA assembly methods and enable new applications. In particular, SEVA 4.0 includes (i) a sub-collection of plasmids for easing the composition of multiple DNA segments with MoClo/Golden Gate technology, (ii) vectors for Gram-positive bacteria and yeast and [iii] off-the-shelf constructs with built-in functionalities. A growing collection of plasmids that capture part of the standard-but not its entirety-has been compiled also into the DB and repository as a separate corpus (SEVAsib) because of its value as a resource for constructing and deploying phenotypes of interest. Maintenance and curation of the DB were accompanied by dedicated diffusion and communication channels that make the SEVA platform a popular resource for genetic analyses, genome editing and bioengineering of a large number of microorganisms.The SEVA repository has been developed and maintained with funds of the SYCOLIM [ERA-COBIOTECH 2018-PCI2019-111859-2] Project of the Spanish Ministry of Science and Innovation, SYNBIO4FLAV [H2020-NMBP-TR-IND/H2020-NMBP-BIO-2018-814650]; MIX-UP [MIX-UP H2020-BIO-CN-2019-870294] Contracts of the European Union; BIOSINT-CM [Y2020/TCS-6555] Project of the Comunidad de Madrid-European Structural and Investment Funds (FSE, FECER); P.I.N. acknowledges financial support by the Novo Nordisk Foundation [NNF20CC0035580, TARGET (NNF21OC0067996]; European Union's Horizon 2020 Research and Innovation Programme [814418 (SinFonia)]; M.H.H.N. acknowledges funding by the Novo Nordisk Foundation [NNF20CC0035580]; P.D. was funded by Czech Science Foundation Project 22-12505S; A.G.M. was supported by the Grants BioSinT-CM [Y2020/TCS-6555]; CONTEXT (Atracción de Talento Program) [2019-T1/BIO-14053] Projects of the Comunidad de Madrid, MULTI-SYSBIO [PID2020-117205GA-I00]; Severo Ochoa Program for Centres of Excellence in R&D [CEX2020-000999-S] funded by MCIN/AEI/10.13039/501100011033 and the ECCO (ERC-2021-COG-101044360) Contract of the EU.

Pancreatic metastases from renal cell carcinoma. Postoperative outcome after surgical treatment in a Spanish multicenter study (PANMEKID)

Background: Renal Cell Carcinoma (RCC) occasionally spreads to the pancreas. The purpose of our study is to evaluate the short and long-term results of a multicenter series in order to determine the effect of surgical treatment on the prognosis of these patients. Methods: Multicenter retrospective study of patients undergoing surgery for RCC pancreatic metastases, from January 2010 to May 2020. Variables related to the primary tumor, demographics, clinical characteristics of metastasis, location in the pancreas, type of pancreatic resection performed and data on short and long-term evolution after pancreatic resection were collected. Results: The study included 116 patients. The mean time between nephrectomy and pancreatic metastases' resection was 87.35 months (ICR: 1.51-332.55). Distal pancreatectomy was the most performed technique employed (50 %). Postoperative morbidity was observed in 60.9 % of cases (Clavien-Dindo greater than IIIa in 14 %). The median follow-up time was 43 months (13-78). Overall survival (OS) rates at 1, 3, and 5 years were 96 %, 88 %, and 83 %, respectively. The disease-free survival (DFS) rate at 1, 3, and 5 years was 73 %, 49 %, and 35 %, respectively. Significant prognostic factors of relapse were a disease free interval of less than 10 years (2.05 [1.13-3.72], p 0.02) and a history of previous extrapancreatic metastasis (2.44 [1.22-4.86], p 0.01). Conclusions: Pancreatic resection if metastatic RCC is found in the pancreas is warranted to achieve higher overall survival and disease-free survival, even if extrapancreatic metastases were previously removed. The existence of intrapancreatic multifocal compromise does not always warrant the performance of a total pancreatectomy in order to improve survival. (C) 2021 The Authors. Published by Elsevier Ltd

Repeated pancreatic resection for pancreatic metastases from renal cell Carcinoma: A Spanish multicenter study (PANMEKID)

Background and objectives: Recurrent isolated pancreatic metastasis from Renal Cell Carcinoma (RCC) after pancreatic resection is rare. The purpose of our study is to describe a series of cases of relapse of pancreatic metastasis from renal cancer in the pancreatic remnant and its surgical treatment with a repeated pancreatic resection, and to analyse the results of both overall and disease -free survival. Methods: Multicenter retrospective study of patients undergoing pancreatic resection for RCC pancreatic metastases, from January 2010 to May 2020. Patients were grouped into two groups depending on whether they received a single pancreatic resection (SPS) or iterative pancreatic resection. Data on short and long-term outcome after pancreatic resection were collected. Results: The study included 131 pancreatic resections performed in 116 patients. Thus, iterative pancreatic surgery (IPS) was performed in 15 patients. The mean length of time between the first pancreatic surgery and the second was 48.9 months (95 % CI: 22.2-56.9). There were no differences in the rate of postoperative complications. The DFS rates at 1, 3 and 5 years were 86 %, 78 % and 78 % vs 75 %, 50 % and 37 % in the IPS and SPS group respectively (p = 0.179). OS rates at 1, 3, 5 and 7 years were 100 %, 100 %, 100 % and 75 % in the IPS group vs 95 %, 85 %, 80 % and 68 % in the SPS group (p = 0.895). Conclusion: Repeated pancreatic resection in case of relapse of pancreatic metastasis of RCC in the pancreatic remnant is justified, since it achieves OS results similar to those obtained after the first resection

Burnout among surgeons before and during the SARS-CoV-2 pandemic: an international survey

Background: SARS-CoV-2 pandemic has had many significant impacts within the surgical realm, and surgeons have been obligated to reconsider almost every aspect of daily clinical practice. Methods: This is a cross-sectional study reported in compliance with the CHERRIES guidelines and conducted through an online platform from June 14th to July 15th, 2020. The primary outcome was the burden of burnout during the pandemic indicated by the validated Shirom-Melamed Burnout Measure. Results: Nine hundred fifty-four surgeons completed the survey. The median length of practice was 10 years; 78.2% included were male with a median age of 37 years old, 39.5% were consultants, 68.9% were general surgeons, and 55.7% were affiliated with an academic institution. Overall, there was a significant increase in the mean burnout score during the pandemic; longer years of practice and older age were significantly associated with less burnout. There were significant reductions in the median number of outpatient visits, operated cases, on-call hours, emergency visits, and research work, so, 48.2% of respondents felt that the training resources were insufficient. The majority (81.3%) of respondents reported that their hospitals were included in the management of COVID-19, 66.5% felt their roles had been minimized; 41% were asked to assist in non-surgical medical practices, and 37.6% of respondents were included in COVID-19 management. Conclusions: There was a significant burnout among trainees. Almost all aspects of clinical and research activities were affected with a significant reduction in the volume of research, outpatient clinic visits, surgical procedures, on-call hours, and emergency cases hindering the training. Trial registration: The study was registered on clicaltrials.gov "NCT04433286" on 16/06/2020
