The representation of entrepreneurship in people with disabilities: a discourse analysis
No full textThe aim of this paper is to identify the main moderating aspects of entrepreneurship
in people with disabilities in Spain in relation to the main explanatory theories on the
subject via a discourse analysis of a group of entrepreneurs and qualified witnesses. Several
key elements were identified in this analysis: physical, accessible, and familial. Attention
to these aspects will contribute to the empowerment of a group at a clear disadvantage
compared to others without disabilities in the entrepreneurial processes. This research
proposes the acquisition, stimulation, and development of a set of knowledge, skills, and
abilities (competencies) together with a greater commitment on the part of the Public
Administration and awareness of society in order to reverse the current starting conditions
of this group
Influence of age and sex on platelet count: implications for optimizing growth factor-rich plasma preparation
No full textBackground: Growth factor-rich plasma (GFRP) is a biomedical procedure used to promote tissue regeneration.
Platelet-rich plasma (PRP) contains higher-than-average platelet concentrations and includes platelet-derived
growth factors. As an autologous blood derivative, it is widely used to enhance healing and tissue regeneration . In
dentistry, GFRP accelerates soft tissue healing and bone regeneration in procedures such as complex extractions,
bone grafts, cyst treatments, and to improve dental implant osseointegration.
Objective: To assess the potential influence of age and sex on platelet count, with the aim of optimizing the standardization
of therapies involving growth factors.
Material and Methods: A cross-sectional, observational, and comparative study was conducted, including a total
of 384 patients. Participants were stratified into six groups based on age. From their medical records, the platelet
counts obtained from analyses meeting the established inclusion criteria were recorded. Subsequently, the distribution
of platelet levels was analyzed according to age groups and sex. Additionally, the potential correlation between
platelet count and age was evaluated.
Results: The mean platelet count was higher in women (260.9 ± 65.9 x10³/μL) than in men (250.4 ± 62.0 x10³/μL),
although the difference was not statistically significant (p = 0.113). A statistically significant negative correlation
was found between age and platelet count (r = -0.175; p < 0.01), indicating that platelet count decreases with age,
although the correlation coefficient was low.
Conclusions: Platelet count varies across the population; therefore, blood extraction for PRP preparation should be
adjusted based on age group and sex
Analysis of Palestinian armed actions in Italy through the Spanish press (1973-1985)
No full textEste artículo analiza cómo la prensa española representó las acciones armadas palestinas llevadas a cabo en Italia entre 1973 y 1985, centrándose en atenta-dos clave como los de Fiumicino, el ataque a la sinagoga de Roma, el secuestro del Achille Lauro y la crisis de Sigonella. El objetivo principal es examinar el papel de los medios como constructores de discurso político en torno al terrorismo internacional, observando cómo se configuró la imagen del militante palestino y qué narrativas dominaron la cobertura. La metodología combina el examen crítico del discurso (van Dijk) con enfoques transnacionales (Saunier, Clavin) y reflexiones sobre memoria y representación mediática (Ricoeur, Zelizer, Assmann). Se estudian artículos de periódicos como ABC, El País, La Vanguardia Española y Diario de Las Palmas, comparando enfoques ideológicos y recursos retóricos. El artículo se organiza en secciones temáticas dedicadas a cada evento, ofreciendo un recorrido cronológico que permite identificar patrones narrativos, cambios de tono y silencios estratégicos en la cobertura periodística española.This article analyzes how the Spanish press represented Palestinian armed actions carried out in Italy between 1973 and 1985, focusing on key incidents such as the Fiumicino attacks, the assault on the Rome synagogue, the Achille Lauro hijacking, and the Sigonella crisis.

This document is the Published version of a Published Work that appeared in final form in Archives of Medical Research. To access the final edited and published work see https://doi.org/10.1016/j.arcmed.2025.103260The increasing prevalence of attention deficit hyperactivity disorder (ADHD) in children has prompted more research on both genetic and environmental risk factors, including endocrine-disrupting chemicals (EDCs) such as bisphenol A (BPA) and polychlorinated biphenyls (PCBs). This review focuses on studies published between
2013 and December 2023 that explore the potential impact of BPA and PCBs on ADHD. The review draws from databases such as WOS, PubMed, and Scopus. BPA, a chemical commonly used in plastics and resins, has raised concerns due to its potential neurodevelopmental effects, particularly when exposure occurs prenatally. Multiple studies have suggested an association between prenatal BPA exposure and an increased risk of ADHD in offspring, though more research is needed. Similarly, PCBs, which are persistent environmental pollutants primarily found in contaminated food sources, have been linked to cognitive and behavioral issues, including attention deficits and hyperactivity. Both BPA and PCBs have been shown to disrupt neurodevelopment,
underscoring the importance of regulating these chemicals to safeguard children’s health. While these findings highlight a potential risk, further studies are required to clarify the underlying mechanisms and the precise role these EDCs play in the development of ADHD and other neurobehavioral disorders
Preferentially Expressed Antigen in Melanoma (PRAME) as a diagnostic and predictive marker in melanocytic tumors: An updated narrative review
No full textMelanocytic neoplasms range from benign nevi to malignant melanomas, and accurate differen-tiation between these lesions is crucial for effective treatment. Among the various immuno-histochemical markers available, PRAME (Preferentially Expressed Antigen in Melanoma) has emerged as a significant diagnostic tool in the evaluation of melanocytic lesions due to its high sensitivity and specificity, particularly in distinguishing malignant melanomas from benign nevi. PRAME is strongly expressed in malignant melanomas, including cutaneous, uveal, and mucosal variants, while its expression is minimal or absent in benign and dysplastic nevi. Its utility extends to identifying metastases, especially in difficult-to-diagnose cases such as metastatic melanoma, where it aids in differentiating melanoma from other malignancies. Additionally, the presence of PRAME is associated with poor prognosis, as higher expression levels correlate with increased metastatic risk. Despite its effectiveness, the use of PRAME in immunohistochemistry is not without limitations. It is not exclusive to melanoma, as its expression can be seen in some non-melanocytic tumors, which may reduce its specificity in certain cases. Nevertheless, PRAME remains a valuable tool in the diagnostic and prognostic evaluation of melanocytic lesions, particularly when histological features are unclear or ambiguous. Further research is needed to refine its role in different melanoma subtypes and to explore its potential as a target for immunotherapy
Imagined and imaginary ethnicities: Herodotus, author of the Persika.
No full textEn el presente trabajo intentamos justificar por qué debemos ver también a Heródoto como a un autor de Persiká. El historiador de Halicarnaso se valió en sus Historias de las mismas técnicas narrativas, de los mismos tropos, de las mismas temáticas y de los mismos clichés orientalistas en su construcción de la etnicidad persa, una etnicidad imaginada e imaginaria sobre la alteridad que ayudara en la definición de la propia etnicidad griega.Abstract: In this paper we try to justify why we should also see Herodotus as an author of Persiká. In his Histories, the historian of Halicarnassus made use of the same narrative techniques, the same tropes, the same themes and the same orientalist clichés in his construction of Persian ethnicity, an imagined and imagined ethnicity of otherness that helped in the definition of Greek ethnicity itself

Dynastic Exaltation in the Compositions of Juan Interián de Ayala on the Birth of Prince Luis Fernando de Borbón
No full textJuan Interián de Ayala compuso un poema en latín dedicado al nacimiento del príncipe Luis Fernando de Borbón, hijo de Felipe V. El texto se publicó en la Relación de las demostraciones de acción de gracias y regocijo que la Universidad de Salamanca editó con motivo del nacimiento del príncipe en 1707, y en Humaniores atque amoeniores ad Musas excursus: sive Opuscula poetica, obra editada por Francisco de Ribera en 1729, que recoge la poesía de Interián de Ayala. El argumento del poema es tanto la victoria del rey Felipe V en la guerra de Sucesión como las festividades por el nacimiento del príncipe. El contenido sobrepasa el marco de un poema genethlíaco y la composición funciona como testimonio de lealtad al rey, quedando patente el apoyo de Interián de Ayala a la nueva dinastía de los Borbones instaurada en España. ---------Juan Interián de Ayala composed a poem in Latin dedicated to the birth of Prince Luis Fernando de Borbón, son of Felipe V. The text was published in the Relación de las demostraciones de acción de gracias y regocijo that the University of Salamanca published on the occasion of the birth of the prince in 1707 and in Humaniores atque amoeniores ad Musas excursus: sive Opuscula poetica (1729), a work that collects the poetry of Interián de Ayala. The plot is both the victory of King Philip V in the War of Succession and the festivities for the birth of the prince. The content goes beyond the framework of a Genethlian poem and the composition functions as a testimony of loyalty to the king, making clear Interián de Ayala’s support for the new Bourbon dynasty established in Spain
