ArticleAntioxidant Potential of Artichoke and Broccoli Leaf Extracts in Oil-in-Water Emulsions Through Different Delivery Systems: Direct Addition, Alginate Films, and Alginate Beads(Springer Science + Business Media, 2026-08-08) Muñoz-Núñez, M.; Codina-Torrella, Idoia; Metón Teijeiro, Isidoro; Almajano Pablos, Ma. Pilar (María Pilar)This study evaluates the antioxidant effectiveness of broccoli and artichoke leaf extracts delivered through different strategies(direct addition, alginate films, and alginate beads) in oil-in-water emulsions as natural antioxidants to prevent lipid oxidation.Leaf extract total polyphenol content (TPC) was determined, with artichoke leaf extract showing higher values (0.89 mgGAE/mL) than broccoli leaf extract (0.47 mg GAE/mL). The extracts were characterized by UHPLC-ESI–MS/MS; broccolileaf extracts were mainly characterized by glucosinolates (glucoiberin and glucoraphanin) together with kaempferol andquercetin derivatives, whereas artichoke extracts were richer in less glycosylated phenolics, including luteolin, apigenin,and hydroxycinnamic acids. Films and beads were analyzed for mechanical properties, morphology, and polyphenol releasekinetics. Beads showed a higher release of the TPC (54.7–78.6%) compared with films (22.6–44% released). Lipid oxidationand semiquantitative distribution of TPC between emulsion phases were also determined. Results showed that artichokesystems exhibited higher antioxidant activity, with lower primary (38.79 meq hydroperoxide/kg emulsion for artichokeleaf extracts at 10%, AL10%) and, also, secondary lipid oxidation. Alginate films and beads incorporating extracts showedsimilar effectiveness to 10% leaf extracts directly added. The highest partition coefficient (ratio of polyphenol in oil phaseand in water phase) was found in emulsions with artichoke leaf extracts (3.7 for AL3.3%) due to its lower polarity nature and,therefore, favoring localization in oil phase and enhancing oxidative protection. Our findings highlight the strong potentialof broccoli and artichoke leaf extracts and alginate systems as natural antioxidants for preventing the lipid oxidation inemulsified food systems.- ArticleEvaluation of chemotherapy-induced nausea and vomiting in low, moderate, and highly emetogenic schemes between sexes(Springer Verlag, 2025-03-10) Albanell Fernández, Marta; Rodríguez Mues, Ma Carmen; Figueras, Carolina; Monge Escartín, Inés; Riu Viladoms, Gisela; Corominas Bosch, Mª Lourdes; Gaba García, Lydia; Altamirano, Mariana; Carcelero San Martin, EstherPurpose Sex influences chemotherapy-induced nausea and vomiting (CINV). However, in clinical practice, males and females receive the same antiemetic prophylaxis. We compared CINV between sexes in patients with different emetic risk schemes and evaluated the predisposing factors and main adverse effects caused by antiemetics. Methods Prospective observational study conducted in a tertiary-care hospital from February 2023 to May 2024 in patients starting chemotherapy or a new treatment line. CINV was evaluated using MASCC antiemetic tool, in acute (< 24 h) and delayed phases (24–120 h). Results were analyzed using χ2 test or Fisher’s exact test. The primary endpoint was complete response (CR) rate, defined as no CINV and no use of rescue medication. Univariate and multivariate logistic regressions were used to identify patient-related risk factors associated with non-CR. Results A total of 176 completed questionnaires (CQ): 94 for males and 82 for females were collected. The proportion of males who remained emesis-free was superior to females in the acute phase (100% versus 92.7%, p = 0.009). Likewise, a higher proportion of males remained nausea-free in the acute (91.5% versus 79.3%, p = 0.021) and delayed phase (90.4% versus 79.3%, p = 0.037). In females, young age (< 60 years) and previous nausea and vomiting during pregnancy may contribute to non-CR. A high proportion of patients reported adverse events like constipation and insomnia. Females suffered more constipation than males (52.4% versus 37.2%, p = 0.043). Conclusion Females experienced more CINV than males, with the consequences that entail. Antiemetic prophylaxis should be personalized, considering sex and age and not only the chemotherapy emetic potential.
- Bachelor thesisEL ACORAZADO POTEMKIN. REVOLUCIÓN, PROPAGANDA Y CENSURA(2026-09-01) González Echevarría, Cristina; Lluís i Falcó, JosepEste trabajo examina la obra de Serguéi M. Eisenstein no solo como referente del cine soviético, sino como pieza catalizadora en la evolución de la historia del arte contemporáneo. El objetivo principal es analizar la recepción crítica y social de El acorazado Potemkin en España, explorando cómo el film desafió las estructuras estéticas y políticas del siglo XX. La metodología combina el análisis formal de la ruptura mediante el montaje intelectual y la estructura dramática de sus cinco actos, con una investigación historiográfica sobre la cultura de masas y el papel de la censura. Los resultados más importantes documentan que, pese a las prohibiciones de la dictadura de Primo de Rivera, Barcelona se consolidó como el epicentro del cine-clubismo y la crítica de vanguardia. La cinta alcanzó un estatus mítico a través de proyecciones semiclandestinas en círculos intelectuales vinculados a la revista Mirador, desafiando el control oficial. Finalmente, el estudio concluye que el film ejemplifica un símbolo de revolución que, aunque restringido inicialmente a una élite, terminó impregnando la estética constructivista y la producción documental nacional. Esta influencia persiste como una paradoja estética frente a una censura oficial que, debido al régimen franquista, se prolongó de forma efectiva hasta 1977, consolidando la obra como un pilar de la resistencia cultural.
- Bachelor thesisSant Esteve als retaules gòtics de Catalunya. Aspectes llegendaris i populars(2026-09-01) Vendrell Herreros, Aina V.; Macías, Guadaira[cat] Aquest treball de final de grau aborda la llegenda de sant Esteve, incloses les seves particularitats en el context medieval de Catalunya, i com aquesta és plasmada en els retaules gòtics catalans, especialment en tres retaules del darrer període gòtic que presenten estretes relacions estilístiques i iconogràfiques entre ells: el retaule de Sant Esteve dels freners, el de Sant Esteve de Granollers i el de Sant Esteve de la Doma. Al llarg del treball s’han revisat tant les fonts textuals que narren la vida de sant Esteve com les aportacions bibliogràfiques al coneixement d’aquests tres conjunts. A través de l’estudi de les tres obres, s’exploren les especificitats de la llegenda, fent èmfasi en la seva vessant més fantasiosa i popular, interrelacionada amb la religiositat i la devoció de la societat catalana de l’època. [eng]This Final Degree Project examines the legend of Saint Stephen including its particularities within the medieval Catalan context, as well as how it is represented in Catalan Gothic altarpieces, with particular emphasis on three altarpieces from the late Gothic period that display close stylistic and iconographic relationships: the altarpiece of Saint Stephen of the Guild of Bridle-Makers, the altarpiece Saint Stephen of Granollers, and the altarpiece of Saint Stephen of La Doma. Throughout this study, both the textual sources recounting the life of Saint Stephen and the existing scholarly literature on these three works have been reviewed. By analysing these three works, the thesis explores the distinctive aspects of the legend, placing particular emphasis on its more imaginative and popular dimension, closely intertwined with the religiosity and devotional practices of Catalan society during the period.
