L'ofici de fuster a la Barcelona del set-cents : noves aportacions documentals, noves mirades

L'aproximació a l'ofici de fuster i la seva evolució com a art mecànica ha estat sempre realitzada en funció de l'artefacte resultant i bàsicament cenyint-se en la construcció de mobiliari. L'atenció per l'evolució estilística del mobiliari ha relegat a un segon terme l'interès per l'entramat d'accions i circumstàncies que configuraven l'activitat laboral en el món de les fusteries, tot menyspreant, fins i tot, l'apropament a unes altres produccions i activitats afins a dit ofici. En el present article, hi proposem una panoràmica que abordi la complexitat de la fusteria al llarg del segle XVIII a Barcelona, mostrant-ne i defensant-ne facetes fins ara poc conegudes. Es tracta de marcar un mapa que ens apropi a la diversitat de tallers existents, tot desgranant-ne els aspectes particulars més rellevants: la formació dels mestres fusters, la producció o fins i tot els plets amb altres gremis. I és en aquesta realitat on pretenem emmarcar i donar a conèixer per primera vegada el disseny de mobles emprats en l'agençament dels interiors benestants barcelonins. Ho farem a partir de l'anàlisi de les traces inèdites incloses, com a prova per intentar establir les competències professionals de cada un, en el llarg i destacat plet civil entre fusters i escultors que va tenir lloc a les darreries del segle XVIII.Discussions of the carpenter's trade and its evolution as a mechanical art have always revolved around the resulting artefact, centring, basically, on the construction of furniture. This emphasis on the stylistic evolution of furniture has relegated as a secondary consideration all interest in the weave of actions and circumstances that characterised working activity in the world of carpentry, to the point, even of eschewing all study of other activities and products with affinities to the trade. This article proposes a more general overview of the complexities of the carpentry trade in Barcelona in the 18th century, providing details about little-known aspects. The aim is to draw a map on which appear all the different workshops that existed in those times, whilst focusing on certain particularly important questions: how master carpenters were trained, what was produced and even disputes with other guilds. And it is within this framework, for the first time, that we seek to discuss the design of furniture used to decorate the homes of wealthy Barcelona families. Our analysis will be based on drawings of this furniture, seen here for the first time, in order to establish the professional fields of all those involved in the long, resounding civil dispute that took place between carpenters and sculptors towards the end of the 18th century

Descritpion of a double mutant strain of Drosophila melanogaster useful for genetic laboratory courses.

Many years ago, individuals showing drastically reduced eyes arose in our laboratory e (ebony) strain (Bridges and Morgan, 1923). We selected those flies presenting both traits and constituted a new double mutant strain e su (e, ebony; su, 'sense ulls', eyes drastically reduced). Both mutations were linked and located in the chromosome III. We used this strain in linkage analyses with our undergraduate students. [...

Productive traits in hybrid hens with Fayoumi maternal genotype

The productive performance during the first laying cycle of two experimental F1 populations of laying hens with Fayoumi maternal genotype and either Rhode Island Red or White Leghorn paternal genotype was evaluated. The Egyptian Fayoumi breed characterized by a low body weight was used to explore its usefulness as a parent stock to diminish maintenance costs of the progeny by reducing its mean body weight. Productive traits at sexual maturity, body weight and egg weight dynamics, form and shape of the egg, feed efficiency for egg production and major egg components were studied. No clear advantage of either of the two hybrids with Fayoumi genotype was evinced. The expectations of enhancing feed efficiency were not accomplished. Although F1 hens were lighter than both paternal lines, their voluntary feed consumption equaled that of the heaviest birds. This fact could be explained in terms of a behavioural response to environmental temperature as these birds, with a natural resistance to hot climates, showed a higher daily intake relative to their body weight when reared during the winter season in a temperate zone

Genomic analyses reveal FoxG as an upstream regulator of wnt1 required for posterior identity specification in planarians

Embryonic specification of the first body axis requires the formation of an Organizer, a group of cells with the ability to instruct fates in the surrounding tissue. The existence of organizing regions in adults, i.e. during regeneration, which also requires patterning of new tissues, remains unstudied. To that aim, we study regeneration in planarians, flatworms that can regenerate any missing structure, even the head, in a few days. In planarians, as described in embryonic models, the cWNT pathway specifies the anterior-posterior axis. During the first 12-24h after amputation both wnt1 and notum (a Wnt inhibitor) are expressed in any wound, but 48 hours later they become restricted to posterior or anterior facing wounds, forming the anterior and the posterior organizers, respectively. In this study we undertook a genomic approach to further understand the mechanism that triggers the early expression of wnt1 and the specification of the posterior identity. Through ATAC-sequencing and CHIPmentation techniques we uncovered Cis-Regulatory Elements of Schmidtea mediterranea genome and analyzed them in notum and wnt1 (RNAi) animals. The result shows that already at 12 hours after amputation the chromatin structure of the wounds has changed its conformation according to the polarity of the pre-existing tissue. Analysing the DNA binding motives present in the proximal regulatory regions of genes down-regulated after wnt1 (RNAi) we found a few genes containing a TCF binding site, which include posterior Homeobox genes and chromatin remodelling proteins, suggesting that those are direct targets of the cWNT pathway and the responsible to trigger the expression of the posterior effectors. Furthermore, we have identified FoxG as an up-stream regulator of wnt1 transcription, probably though binding to an enhancer found in its first intron. Silencing of foxG inhibits the early phase of wnt1 expression and phenocopies the wnt1 (RNAi) phenotype, indicating its early role in specifying posterior versus anterior identity. Moreover, we have created a new open platform to interpret all transcriptomic and genomic results obtained (https://compgen.bio.ub.edu/PlanNET/planexp)

Relevamiento de parásitos zoonóticos y no zoonóticos en materia fecal canina y su importancia para la salud pública en la comunidad de Santa Lucía, partido de San Pedro, Buenos Aires.

La contextualización en proyectos de extensión genera que los estudiantes universitarios deban trabajar con tareas auténticas y significativas culturalmente, y necesitan aprender a resolver problemas con sentido social. A través de esta estrategia pedagógica (aprendizaje-servicio) se analizaron uno de los datos obtenidos en el proyecto Ubanex “Colaboremos con Santa Lucía”. Introducción. La comunidad de Santa Lucia (Pdo. De San Pedro, Bs. As.), presenta una población canina estimada en 650 animales, una alta proporción sin propietario. Esta situación genera alta contaminación ambiental a través de materia fecal canina, incrementando la probabilidad de infestación por parásitos zoonótico. El objetivo del presente trabajo fue detectar parásitosis zoonóticas y tomar medidas sanitarias acorde a los resultados obtenidos a partir de las distintas muestras, las obtenidas en la vía pública y las recolectadas por el Proyecto de Extensión (UBANEX) que pertenecen a caninos con dueño. Materiales y métodos: Entre Agosto de 2011 y Abril del 2012 se realizaron 118 exámenes coproparasitológicos . Las muestras se procesaron mediante la técnica de flotación-sedimentación de Willis. Se calcularon las prevalencias de parásitos totales, los porcentajes por especie y los porcentajes de muestras monoparasitadas y poliparasitadas. Resultados: Los parásitos identificados fueron: Trichuris vulpis, Ancylostoma caninum, Toxoascaris leonina, Toxocara canis, ooquistes de coccidios, Giardias sp.y Dipylidium caninum. La prevalencia total de parásitos fue significativamente mayor en los animales muestrados pertenecientes a integrantes de la comunidad pueblerina. Siendo también superior el porcentaje de muestras poliparasitadas con respecto a las muestras monoparasitadas. Conclusiones. Los resultados de este estudio demuestran una alta prevalencia de enteroparásitos de importancia zoonótica. En base a estos resultados se distribuyeron antiparasitarios, donación de laboratorio “Vetanco” logrando tratar a 300 caninos. Se realizaron pequeñas jornadas técnicas en las escuelas medias, sobre “Zoonosis parasitarias encontradas en Santa Lucía”. Se genero un mapa catrastal de zoonosis diagnosticadas, y se entrego al Hospital Municipal de Santa Lucía, un informe técnico. A pedido de la Municipalidad se planifico un ciclo de conferencias técnicas a desarrollar en el corriente año, tres campañas antiparasitarias anuales en la población de referencia y en el marco de un nuevo proyecto de extensión el relevamiento de nuevas zoonosis que puedan estar presentes en dicha comunidad rural.

Considering and interpreting leisure: pastimes, entertainments, hobbies and addictions in the Barcelona of 1900

Coordinació: Teresa-M. SalaIn the throes of modernization, the Barcelona of 1900 was buzzing with energy and an unprecedented culture of leisure emerged. The city’s residents made full use of their free time, forging relationships with one another through a highly varied range of initiatives and activities, taking advantage of existing opportunities and creating new ones. In addition to the traditional celebration of civic festivals, popular meals and various types of processions, innovative new forms of cultural consumption sprang up to satisfy all tastes and budgets. Numerous cinemas opened, the first amusement parks threw open their gates and new theatres raised their curtains. Thanks to these developments, the vicinity around the avenue Paral·lel became the epicentre of Barcelona nightlife. This book offers a panoply of images of the diversions, entertainments and hobbies of that fascinating era of contrasts, the turn-of-the-century Barcelona of Modernisme
