Electrochemotherapy intralesional treatment in a captive peregrine falcon (Falco peregrinus) with dermal squamous cell carcinoma
(MDPI, 2025) Peña, Sara; Ferrer, Otilia; Balañá, Beatriz; Lima, Mariana; Ordeix, Laura; Alomar, Jaume
Captive birds of prey often exceed their wild counterparts’ lifespan, as seen in bald eagles (Haliaeetus leucocephalus, ~20 years wild vs. ~40 years captive), golden eagles (Aquila chrysaetos, ~32 years wild vs. ~46 years captive), and Andean condors (Vultur gryphus, ~50 years wild vs. ~79 years captive), highlighting the impact of controlled environments on longevity. However, recent evidence suggests a rising incidence of neoplastic processes in these species. While previous studies have indicated a higher-than-expected prevalence of neoplasia in raptors, comprehensive research on this topic remains scarce. Squamous cell carcinoma (SCC), a frequently reported neoplasm in pet birds, has been documented in birds of prey, though the literature on its prevalence and management is limited. Retrospective studies have identified SCC cases in peregrine falcons (Falco peregrinus), primarily affecting the flank or thigh, with locally invasive behavior and rare distant metastasis. Complete surgical excision is the preferred treatment for SCCs, yet its feasibility is often constrained by tumor invasiveness and anatomical limitations. Electrochemotherapy (ECT) has emerged as a promising alternative, utilizing electroporation to enhance intracellular drug uptake while minimizing systemic toxicity. Bleomycin and cisplatin have been successfully used in avian intralesional chemotherapy, offering a potentially safer and effective treatment approach. ECT has demonstrated efficacy in various exotic species, yet its application in raptors remains largely unexplored. This case report describes the use of electrochemotherapy with bleomycin in a peregrine falcon diagnosed with SCC, contributing to the growing body of evidence supporting its clinical utility in avian oncology.

Investing in a New Financial Instrument: The First Buyers of Urban Debt in Catalonia (Mid. 14th Century)
(De Gruyter Oldenbourg, 2025-04-03) Miquel Milian, Laura; Reixach Sala, Albert; Verdés Pijuan, Pere
This article consists of a systematic analysis of a large sample of the first purchasers of annuities issued by the urban governments of Catalonia between the years 1313 and 1367. Based on preliminary literature on the subject, it gathers, describes, and contextualizes, both from the point of view of the fiscal and financial development of the Crown of Aragon as a whole and from a more local perspective, unpublished references to operations of this type from the beginning of the 14th century. In the second part, it analyses a sample, based on unedited data as well as specific studies, of 1,399 annuities sold by eight urban centres between the years 1330 and 1367 (the settlements are in different parts of Catalonia, ranging from big cities like Barcelona or Girona to small towns). These operations are examined according to their chronology, features of contracts and interest rates. Moreover, their buyers are also studied in light of their gender, socioeconomic status, and place of residence. The first purchasers of public debt in Catalonia appear to have been speculative investors, attracted by a financial product that, while lacking complete security, offered high interest rates and the theoretical promise of recovering the capital upon repayment of the credit.

Projecte executiu de dues sales blanques per l'Hospital Universitaro Santa Maria
(2025-03) Campi Aragon, David
Aquest projecte té com a objectiu la implantació de dues sales blanques localitzades a l’Hospital Universitari Santa Maria, de Lleida. Es realitzarà una descripció, disseny i dimensionat de la instal·lació per tal de fer-la el més adient possible. A partir d’uns requeriments establerts per part de la GSS (Gestió de Serveis Sanitaris), empresa pública que gestiona el funcionament de l'Hospital Santa Maria de Lleida, i d’un projecte d’amidaments realitzats prèviament, l’objectiu és poder calcular, dissenyar i construir les instal·lacions assegurant el correcte funcionament de les sales blanques. Per tant, s’analitzarà i es calcularà les instal·lacions de ventilació, clima, fontaneria i electricitat. D’aquesta manera, i considerant els requeriments i les necessitats específiques d’aquest tipus d’instal·lacions, es duran a terme els càlculs necessaris per garantir el confort, la seguretat i la lluminositat, complint amb els requeriments establerts per la normativa vigent. Finalment es plantejaran totes les instal·lacions esmenades en un seguit de plànols per tal de conèixer les dimensions i mesures reals, facilitant la creació d’un pressupost final amb les correctes mesures finals de cada element.

¿Puede el agua cambiar estructuras e identidades sociales y culturales? L'estany d'Ivars (Lleida)
(Universidad de Jaén, 2025-04-10) Tahull Fort, Joan
L'Estany d'Ivars (comarca del Pla d'Urgell, en la provincia de Lleida) se recuperó para los vecinos y la población en general después de ser desecado en 1951. El estanque modificó el ecosistema, el paisaje, la fauna, la flora y también la identidad de los vecinos. El Pla d'Urgell pasó de no tener turismo (antes de la recuperación del estanque) a ser lugar de atracción turística por su especial y singular paisaje. El agua transformó la comarca. Se presenta información obtenida mediante observación participante y se han realizado 10 entrevistas a técnicos responsables del Consorci, vecinos y visitantes. Según la información proporcionada por los entrevistados; el estanque cambió la identidad de los vecinos de los pueblos cercanos y han adquirido una identidad más positiva y empoderada; se sienten más orgullos y satisfechos de su lugar de residencia.

Climbing up through Self-Regulated Learning (SRL): a comparative analysis of SRL processes among pre-service an in-service schoolteachers
(Asociación Universitaria de Formación del Profesorado, 2025-04-18) Rodríguez Gómez, David; Flores i Alarcia, Òscar; Muñoz Moreno, José Luís; Ion, Georgeta
The quality of our educational systems depends, among many other factors, on the involvement, autonomy and professional development of teachers. Self-regulation capacity and, specifically, the self-regulation of learning is one of the key factors contributing to the academic and professional development of teachers. The purpose of this study is to delve into the understanding of pre-service and in-service schoolteachers' self-regulated learning processes, as part of their professional competencies' development. Through a qualitative methodology, semi-structured interviews, designed ad-hoc for the study, were conducted with eleven pre-service and twelve in-service schoolteachers. The interviews addressed aspects associated to the planning, the monitoring, andthe reflection of their learning processes and professional development. Results show that self-regulated learning is an ability that is learned during their initial training, and which is continuously developed and defined during their professional practice, which shifts from the individual to the collective, and which is regulated through motivation. The study leads us to conclude that without a doubt, the development of self-regulation of learning processes improves and completes the professional practice of teachers. Therefore, it is necessary to incorporate self-regulated learning in the study plansof schoolteacher's training and the school's strategic plan, as a key competency that must to be developed in an intentional, planned, and conscious manner.
