RADES axion search results with a high-temperature superconducting cavity in an 11.7 T magnet
Full text linkWe describe the results of a haloscope axion search performed with an 11.7 T dipole magnet at CERN. The search used a custom-made radio-frequency cavity coated with high-temperature superconducting tape. A set of 27 h of data at a resonant frequency of around 8.84 GHz was analysed. In the range of axion mass 36.5676 μeV to 36.5699 μeV, corresponding to a width of 554 kHz, no signal excess hinting at an axion-like particle was found. Correspondingly, in this mass range, a limit on the axion to photon coupling-strength was set in the range between gaγ ≳ 6.3 × 10−13 GeV−1 and gaγ ≳ 1.59 × 10−13 GeV−1 with a 95% confidence level
Evaluation of the antimicrobial effect of a nanoemulsified D-limonene washing solution for cherry tomatoes against Staphylococcus aureus and Meyerozyma guilliermondii – Impact on consumer protection
Full text linkAlthough a washing step is essential for the safety of fresh vegetables, chlorine-based solutions may have negative effects on workers and consumers. This study evaluates an alternative washing solution based on nanoemulsified D-limonene against Staphylococcus aures (a relevant pathogen) and Meyerozyma guilliermondii (a model spoilage yeast) on cherry tomato surface. The antimicrobial effect depended on both the EO concentration (1 mM–200 mM) and different exposure time (0.5–15 min). The EO washing solution caused up to 1.7 ± 0.2 log-reductions in M. guilliermondii, being even more effective than the commercial one (1.3 ± 0.1 log-reductions). As the effect of the EO solution on S. aureus was lower (1.4 ± 0.3 vs. 1.7 ± 0.2 log-reductions), consumer protection was evaluated using a QMRA. Although exposure would be higher due to the slightly lower antimicrobial effect, this would not impact consumer protection (median estimate of 0 cases per 1,000,000 servings, with 90th percentile of 1.9·10−7 in both cases). Therefore, despite further research being needed to ensure the commercial viability of these alternative washing solutions, our results emphasize their great promise as an alternative food safety control system
Relating to a new body: understanding the influence of body compassion and metacognition on body image in breast cancer survivors
Full text linkBody compassion is a multidimensional construct related to body image and self-compassion and refers to one’s dispositional attitude towards oneself. Although the overall protective role of body compassion on body image issues, there is a lack of understanding in the oncological field. This exploratory study assesses the impact of body compassion, and metacognition on body image in breast cancer survivors, and how it is affected by cognitive and emotional issues. 79 breast cancer survivors filled in socio-demographic data and standardized online questionnaires. Results evidenced that body compassion has a significant effect on body image. Defusion and acceptance subscales negatively impact body image distress, while negative beliefs about worry as metacognition subscales positively predict body image distress. Indeed, promoting body compassion and decreasing a metacognition tendency can be a therapeutic target to promote a better body image in breast cancer survivors
Valorization of Solanum melongena L. crop by-products: Phenolic composition and in vitro antioxidant, antidiabetic, anti-inflammatory, cytotoxic, and antimicrobial properties
Full text linkThis study explored the valorization of post-harvest eggplant aerial parts as a sustainable source of value-added ingredients by investigating their phenolic composition and in vitro bioactive properties. HPLC-DAD-ESI/MSn analysis identified chlorogenic acid derivatives as the predominant phenolic compounds (53 % of the phenolic fraction), followed by O-glycosylated kaempferol and quercetin. The extract displayed antioxidant activity in physiologically relevant cell-based assays and significant α-glucosidase inhibitory capacity that far exceeded that of the standard drug acarbose. It also inhibited the formation of advanced glycation end-products (AGEs), suggesting its potential to mitigate diabetes-related complications. Furthermore, the extract showed a modest pancreatic lipase inhibitory effect and capacity to suppress interleukin 6 production. Selective cytotoxicity against human gastric and colon adenocarcinoma cell lines and strong antimicrobial activity against foodborne pathogens were observed. Given the growing demand for natural alternatives to synthetic drugs, these findings position eggplant crop biomass as a promising, sustainable source of active compounds with potential applications in food, nutraceutical, and pharmaceutical formulations for managing type 2 diabetes and other oxidative stress-mediated conditions. This study not only contributes to the valorization of agricultural waste but also expands the research on by-products of Solanaceae crops, offering a pathway for sustainable resource utilization
“For Better, for Worse”: The Role of Siblings in Survival and Biological Well-Being in Rural Aragón (Spain) in the Twentieth Century
Full text linkThis article examines the evolution of the role played by the number and gender of siblings in the survival and biological well-being of individuals in rural Spain during the twentieth century. Our aim is to test how two fundamental theories – the cooperative breeding hypotheis and the resource dilution hypothesis – about how the number of siblings affect the individual come together in this area of study during a period of economic, health, and social transformation. We used a sample of 19,331 individuals born between 1900 and 1979 from 14 rural villages, for whom data on sibling count and various family and environmental variables are available. Using these data, we ran several statistical models to discover the effects of siblings on survival. In addition, we studied the long-term effect of siblings on height using height data from 2,783 male conscripts. Our results show that the number of siblings positively influenced survival, either through the cooperation of older siblings in the care of their younger brothers and sisters or through parents exhibiting higher offspring survival abilities. However, increased reproductive success may come with a disadvantage. The biological well-being, as measured by height, of male conscripts was significantly lower among individuals with more siblings in the early decades of the study. Conversely, in the later decades, the negative relationship between sibship size and height was not statistically significant when the number of living siblings was fewer than five
Exequátur sobre incapacidad y privación de derechos en materia electoral. Un estudio desde la perspectiva del DIPr y del Derecho comparado, a la luz de la sentencia de la Corte Suprema de Chile emitida en el Rol nº 87.878-2023
Full text linkEste trabajo se centra en el estudio de un exequátur sobre incapacidad y privación de derechos en materia electoral. En concreto, se analiza una sentencia de la Corte Suprema de Chile, dictada en el Rol Nº 87.878-2023, que reconoce y ejecuta una sentencia española, anterior a la entrada en vigor de la Ley 8/2021, que declaró la incapacidad total de una persona y decretó la privación de su derecho de sufragio. Dado el interés suscitado por la citada sentencia chilena, tanto desde la perspectiva del Derecho Internacional privado como del Derecho civil comparado, se confrontan los elementos internacionales y materiales que vinculan en este caso a los ordenamientos jurídicos español y chileno. A tal efecto, en forma previa, y en relación con la materia que aquí interesa, se abordan algunas disposiciones de la Convención sobre los Derechos de las Personas con Discapacidad, el Convenio de La Haya, de 13 de enero de 2000, sobre Protección Internacional de los Adultos, la Ley de Cooperación Jurídica Internacional en materia civil, la Ley Orgánica 2/2018 y la Ley 8/2021
New iterative methods for fixed point approximation: application to the numerical solution of Fredholm integral equations
Full text linkThis paper provides new insights to the search and approximation of fixed points of non-contractive operators. It analyzes the role of the concepts of demiclosedness and demicompactness in the existence of critical points, giving sufficient conditions for their existence. Both notions are related to the construction of approximation sequences of the fixed points, that provide iterative algorithms for the resolution of equations of all kinds. In this paper, two different algorithms are proposed, and their convergence is studied in the framework of normed and quasi-normed spaces. The sequences are composed of weighted averages of the variable and its image by the operator. They aim to be an alternative to Picard’s method, when this procedure does not converge. These algorithms are applied to the numerical solution of a Fredholm integral equation of second kind, that appears in a great number of problems of physics, engineering and applied mathematics. The methods are checked in a particular case of Fredholm integral equation with exact solution, in order to compute the errors committed by the different approximations, and illustrate the convergence of the iterations to the real solution
Las obras escultóricas de los Talleres de Arte Granda de Madrid para los pueblos de colonización de la cuenca del Ebro en la posguerra
Full text linkEl objetivo de este texto es analizar las obras escultóricas realizadas por la empresa madrileña Talleres de Arte Granda para los pueblos creados por el Instituto Nacional de Coloniza-ción en la cuenca del Ebro, principalmente en las provincias de Zaragoza, Huesca, Teruel, Lérida y Navarra. Estas esculturas, fechadas en el periodo de la posguerra, está datadas en los años ‘60 y 70’. Granda, que se constituye como la empresa que mayor número de obras artísticas suministró a estos nuevos núcleos, contó para ello con una importante nómina de artistas, aunque la mayoría de estas piezas fueron remitidas como procedentes de los citados talleres, sin concretar su autoría. No obstante, en algunas de ellas se ha atribuido la ejecución de los modelos originales, como es el caso de los escultores José Capuz o Lorenzo Frechilla.
The aim of this text is to analyze the sculptural works carried out by the Madrid com-pany Talleres de Arte Granda for the towns created by the National Institute of Colonization in the Ebro basin, mainly in the provinces of Zaragoza, Huesca, Teruel, Lérida and Navarra. These sculp-tures, dated to the post-war period, date back to the 1960s and 1970s. Granda, which is the com-pany that supplied the largest number of artistic works to these new towns, had a significant list of artists to do so, although the majority of these pieces were sent as coming from the aforementioned workshops, without specifying their authorship. However, in some of them the authorship of the original models has been attributed, as is the case of the sculptors José Capuz or Lorenzo Frechilla
Double dehiscence (Superior semicircular canal and tegmen tympani) in the epicampaniform period (Arboli type)
Full text linkPurpose
Although the superior semicircular canal dehiscence syndrome was described at the end of the 20th century, we want to check if it is a pathology that has existed since ancient times, through the anthropological study of bone remains.
Methods
We have carried out an anthropological and radiological study (CT scan) of 8 skulls found in caves, as secondary burials of the Arbolí type epicampaniform culture (1800 − 1700 BC) on the Iberian Peninsula.
Results
The 8 skulls (16 temporal bones) show a grade 4 degree of pneumatisation or hyperpneumatization. One of these skulls, belonging to a male subject of around 25–30 years of age, shows a double dehiscence (superior semicircular canal and tegmen tympani) on the right side, and a possible congenital muscular torticollis on the same side.
Conclusion
Superior semicircular canal dehiscence syndrome already existed in an inhabitant from 1800 − 1700 BC (Iberian Peninsula). This is the first case in which the association of both dehiscences (superior semicircular canal and tegmen tympani) has been demonstrated
Pretransplant Physical Activity and Cardiovascular Risk Factors in Kidney Transplant Candidates: A Cross-Sectional Study
Full text linkBackground/Objectives: Individuals with chronic kidney disease often face significant physical and clinical challenges, such as muscle weakness, fatigue, and reduced cardiorespiratory capacity, that impact their quality of life. Physical activity has emerged as an effective intervention to counteract these effects, with clinical guidelines recommending exercise as a standard treatment for kidney transplant recipients. The aim of this study was to assess pretransplant physical activity levels in a cohort of transplant patients and analyze their relationships with cardiovascular risk factors. Methods: A cross-sectional, analytical, and correlational study was conducted from September 2020 to June 2022 with a sample of 122 kidney transplant recipients assessed before kidney transplantation. Sociodemographic data, anthropometric data, comorbidities, renal replacement therapy types, and clinical and analytical data were collected from the patients’ clinical records. Physical activity was assessed via the International Physical Activity Questionnaire. Results: The average time spent waiting for transplantation was 423 ± 405 days, which was longer (387 ± 524) in the group of those under 65 years than in those over 65 years (194 ± 256) (p = 0.010). The median energy expenditure was 1742 (IQR = 1719) METs. In addition, 15.6% of the participants reported inactivity. Men reported higher physical activity levels (median: 2076 METs/week; IQR: 2037) than women did (median: 1386 METs/week; IQR: 1238). A higher level of physical activity was found in non-dialysis patients, overweight patients, and those with a history of stroke. A significant positive correlation was found between physical activity levels and serum urea. Conclusions: Increased physical activity levels were observed in men and in participants under 65 years of age. Patients with cardiovascular risk factors, such as hypertension, diabetes mellitus, dyslipidemia, overweight and obesity, reported lower activity levels, whereas those with a prior history of cerebrovascular accidents engaged in more physical activity. This study highlights the importance of assessing physical activity and promoting exercise for chronic kidney disease patients awaiting kidney transplantation. Further research is needed to explore the evolution of physical activity in this population and its impact post-transplantation
