Los límites éticos y normativos de la libertad de expresión pública del juez
(Dykinson, 2025-04-23) CARRETERO SÁNCHEZ , SANTIAGO
Esta obra colectiva busca crear un espacio de debate y reflexión serena sobre el derecho a la libertad de expresión de los jueces, reconocido constitucionalmente, a la luz de la ética judicial, con el objetivo de aumentar la confianza de la ciudadanía en la Administración de Justicia. A través de un estudio profundo realizado por numerosos juristas desde diversas perspectivas, se enfatiza que cuando la actividad profesional requiere excelencia, el mero cumplimiento de las normas jurídicas es insuficiente. Sin ética, el Derecho se convierte en un entramado inerte, carente de alma.
“The 15 Players' Tantrum” Social Networks and Women's Football through the Documentary #SeAcabó: Diario de las campeonas
(VisualCOM Scientific Publications, 2025-04-12) Dueñas Mohedas, Sonia; Martínez Pérez, Natalia; Cuenca Orellana, Nerea
The non-consensual kiss between the former president of the RFEF, Luis Rubiales, and the footballer Jennifer Hermoso during the World Cup'23 triggered the #SeAcabó movement on social networks, thereby bringing to light the influence peddling and sexist practices hidden behind women's sport. The impact of these events was subsequently covered by both national and international media. From the perspective of cultural and gender studies, this article analyses the documentary #SeAcabó: Diario de las campeonas (Joanna Pardos, 2024) to study the obstacles and prejudices faced by women in the world of football during their professionalisation.
El beso no consentido entre el expresidente de la RFEF, Luis Rubiales, y la futbolista Jennifer Hermoso durante la Copa Mundial’23 activó el movimiento #SeAcabó en las redes sociales. Esto acabó destapando el tráfico de influencias y prácticas sexistas que se esconden tras el deporte femenino y cuyo impacto fue recogido por los medios de comunicación nacionales e internacionales. Desde los estudios culturales y de género, este artículo analiza el documental #SeAcabó: Diario de las campeonas (Joanna Pardos, 2024) para estudiar los obstáculos y prejuicios a los que se enfrentan las mujeres en el mundo del fútbol en su profesionalización.

Spherical C18-functionalized ordered mesoporous silica packed on micro-solid phase extraction cartridges for simultaneous determination of twenty-three alkaloids in flower extract supplements

A spherical ordered mesoporous silica functionalized with octadecylsilane ligand (SM-C18) was successfully synthesized and characterized, showing 647 m2/g of surface area, 45 Å of pore size, 4–6 μm of particle diameter and 0.37 mmol/g of functionalization degree. 1.5 mg of SM-C18 were packed into EPREP micro-solid phase extraction (μSPEed) cartridges for use with a handheld programmable digital analytical syringe (digiVOL®) to develop a sample preparation protocol for the analysis of two tropane (TAs) and twenty-one pyrrolizidine (PAs) alkaloids. The SM-C18 demonstrated greater retention capacity compared with commercial C18/hydrophilic amorphous silica sorbent. The optimized extraction conditions were as follows: 100 μL of methanol (2 cycles) and 100 μL of H2O (2 cycles) for conditioning, 100 μL of H2O-reconstituted sample (10 cycles), for a total of 1 mL of sample loaded, and 100 μL of methanol (2 cycles) for elution, followed by subsequent analysis by UHPLC-MS/MS. The method was successfully validated, showing good recoveries ranging between 91 and 97 %, low quantification limits and absence of matrix effect for the twenty-tree alkaloids. Additionally, cartridges packed with SM-C18 material allow for better reusability compared to the commercial material, as it has been demonstrated that they can be used for at least 75 extractions. This significantly enhances the method’s sustainability. Finally, it was applied to 25 samples of flower extract supplements (FES). In two different batches of the sample obtained from Convolvulus arvensis flowers (FES4a and FES4b), atropine and scopolamine were quantified.
Edible Flowers in Modern Gastronomy: A Study of Their Volatilomic Fingerprint and Potential Health Benefits
(MDPI, 2025-04-17) Fernández-Pintor, Begoña; Perestelo, Rosa; Morante-Zarcero, Sonia; Sierra, Isabel; Câmara, José S.
Given the transformation that gastronomy has undergone in recent years, there is a need to characterize some new foods that are being incorporated into the modern diet. Among them, edible flowers stand out, which are used today not only to enhance the organoleptic properties of gourmet dishes but also for some of the beneficial properties they provide to human health. In this study, the volatilomic fingerprint of seven edible flowers that are used daily in Michelin-starred restaurants on Madeira Island was established. For this purpose, the extraction of volatile organic metabolites (VOMs) was carried out using the headspace solid-phase microextraction (HS-SPME) technique followed by gas chromatography coupled to mass spectrometry (GC-MS). The results showed a wide variability among the analyzed flowers. While fewer VOMs were detected in some flowers, other flowers, such as Viola tricolor and Rosa spp., exhibited a greater number of these compounds. Acmella oleracea had the highest number of detected VOMs. Each of these VOMs contributes to the characteristic aroma representative of the respective flower, highlighting their potential health benefits, as some are known for their anti-inflammatory, antimicrobial, and even anticancer properties.
