La relación entre la sociedad y la religión se hace patente en las múltiples manifestaciones de las personas. La forma particular de vivir la religiosidad en Andalucía, sobre todo en Sevilla y en su área de influencia, hace que todo el año esté marcado por la existencia de ritos públicos que van a ir dejando huellas en el paisaje lingüístico de las ciudades. En este trabajo se analizan los tipos de textos que suelen aparecer en el paisaje lingüístico de temática religiosa en una localidad andaluza, destacando las características propias de este tipo de textos. Para ello, se parte de una contextualización de la zona de estudio y se presenta el corpus de textos. El corpus se analiza siguiendo los criterios de clasificación de PLANEO, para después proponer unos criterios clasificatorios de este tipo de textos según su finalidad.

Fold-fold singularities are critical points or singularities in piecewise smooth dynamical systems (PWS) where both the stability and the structure of the system change. These singularities are of great importance in the study of specific dynamics, such as those in markets, as they indicate significant transformations in their evolution, including sudden variability in prices or changes in the behavior of offers and demand. Despite the substantial increase in the use of mathematical and computational tools applied to market dynamics, the current literature does not thoroughly address the study of the existence of fold-fold singularities in piecewise smooth systems within this context. Therefore, due to the importance of markets as economic activities, this paper proves the existence of such a singularity in a mathematical model that describes the dynamics of a stockless market, which is represented by a system of ordinary differential equations defined with piecewise smooth functions.

Tras los tradicionales altos crecimientos de la economía china en los años anteriores a la pandemia de la COVID-19, aun cuando estos no eran ya de dos dígitos, el ritmo cayó significativamente en 2020. Parecía que, en 2021, se iba a recuperar, cuando se extendió al 8 por ciento; sin embargo, la incidencia de la pandemia, junto a dificultades internas y del contexto internacional, hicieron que el incremento fuera nuevamente bajo en 2022. Todo ello ha venido a reforzar juicios negativos que abundan en la literatura acerca de la capacidad y las perspectivas de la economía china, los cuales, sin dejar de abordar hechos ciertos, en ocasiones exageran u ofrecen un enfoque sesgado. A pesar de la situación menos favorable que enfrentó la economía china en 2022, en comparación con periodos anteriores, esta debe mantener su liderazgo en el escenario mundial, reafirmándose como la segunda mayor economía después de Estados Unidos, principal exportadora, segunda importadora de bienes, con un papel ascendente en las finanzas internacionales y una mejoría en los indicadores sociales, todo lo cual confirma su intención de elevar continuamente el nivel de vida de su población.

In food analysis, conventional one‐dimensional liquid chromatography methods sometimes lack sufficient separation power due to the complexity and heterogeneity of the analyzed matrices. Therefore, the use of two‐dimensional liquid chromatography (2D‐LC) turns out to be a powerful tool to consider, especially when coupled to mass spectrometry (MS). This review presents the most remarkable 2D‐LC–MS food applications reported in the last 10 years, including a critical discussion of the multiple approaches, modulation strategies as well as the importance of the optimization of the different analytical aspects that will condition the 2D‐LC–MS performance. The presence of contaminants in food (food safety), the food quality, and authenticity or the relationship between the beneficial effects of food and human health are some of the fields in which most of the 2D‐LC–MS applications are mainly focused. Both heart‐cutting and comprehensive applications are described and discussed in this review, highlighting the potential of 2D‐LC–MS for the analysis of such complex samples. [ABSTRACT FROM AUTHOR]

Postcricoid vascular alterations are infrequent entities in otorhinolaryngology. Most Postcricoid vascular alterations correspond to anatomical variations of the vascular plexuses that depend on changes in abdominal pressure. CLINICAL CASE: Infant consultation for recurring upper respiratory infections associated with dysphonia and stridor while crying. Physical examination: nasal and oral cavity without pathological findings. Flexible endoscopy: vascularized tumor in postcricoid region, variable with crying. Neck MRI: Hyperintense linear postcricoid image in T2 and STIR sequences. Patient was managed cautiously, evolving with regression of symptoms and progressive regression of vascular tumor. DISCUSSION: Postcricoid vascular anomalies are venous proliferations that resemble a variable vascularized mass with changes in abdominal pressure. These alterations would be secondary to hypopharyngeal venous “cushions” or plexuses that regress with age. The symptoms vary and can present in infants with stridor, dysphonia, apneas, dysphagia, and even slow weight gain. These lesions are identifiable by awake flexible laryngoscopy and are not evidenced by rigid laryngoscopy or imaging under anesthesia unless Valsalva or Trendelenburg maneuvers are used. It is recommended to rule out synchronous lesions in the aerodigestive tract. Differential diagnoses are congenital laryngeal vascular anomalies and postcricoid hemangiomas, which are not altered with pressure changes. Treatment will depend on the severity of the symptoms. CONCLUSIONS: Hypopharyngeal venous plexuses are entities that are not much described in literature. They can cause a variety of symptoms and should always be considered in infants with aerodigestive symptoms and postcricoid abnormalities.

Introducción: La vacunación es una herramienta esencial en la prevención de enfermedades altamente contagiosas. Actualmente, dicho procedimiento comienza a ser menos empleado debido, entre otros, a diversos factores económicos y sociales, que han promovido la reaparición de patologías que estaban prácticamente desaparecidas. Objetivos: Definir el estado inmunitario de los trabajadores sanitarios del Hospital de Poniente de la provincia de Almería y observar la eficacia de las vacunas administradas por el Servicio de Prevención en el personal sanitario no inmunizado. Metodología: Estudio descriptivo en el que se evalúa mediante serología, la inmunidad frente al sarampión, la rubéola, la parotiditis, la varicela y la hepatitis B previa y posterior a la administración de vacunas en el personal sanitario (n = 923). Resultados: Se observa un alto porcentaje de la población trabajadora sanitaria con anticuerpos protectores frente a los microorganismos del estudio, ya sea por una correcta pauta vacunal en la infancia como por la posterior vacunación por parte del Servicio de Prevención (alta tasa de seroconversión). Conclusión: El estudio señala la importancia de la vacunación como medida preventiva contra las enfermedades estudiadas, por lo que justifica la necesidad de poner en marcha campañas informativas que refuercen su uso.

El café es una de las bebidas más consumidas en el mundo, y Colombia tiene cualidades excepcionales para su cultivo, producción e industrialización. El objetivo de este trabajo fue evaluar mediante catación, la calidad en taza de cuatro variedades de café, de origen colombiano (exactamente del Departamento del Quindío), de la especie Coffea arabica L. Se realizó un estudio de tipo cualitativo- y descriptivo, apoyado en un diseño experimental de dos factores, para el cual se escogieron las variedades: Geisha, Bourbon rosado, Moka y Castillo, los tres primeros son cafés especiales y el último es una variedad de porte medio, cuya calidad en taza es comparable con las otras. Para la evaluación en taza, se realizaron tres niveles de tostión; se encontró que la variedad Geisha obtuvo la mayor puntuación en sus tres niveles de tostión, y entre éstos, el nivel de tostión bajo resaltó más sus cualidades. Finalmente, se concluye que la variedad del café es uno de los factores que influye en la calidad de taza.

The current COVID-19 pandemic has generated a series of changes in the daily routines of people, including children and teenagers, in an unprecedented way, which constitutes a global challenge in public health. Social isolation has been a prophylactic measure to prevent the spread of the virus; however, it has generated negative impacts on the physical and emotional health of parents, caregivers, children and teenagers around the world. The objective of the present study was to evaluate the effects of confinement caused by the COVID-19 pandemic at the level of nutritional status, dietary and behavioural patterns of elementary school children and teenagers in a small town of Colombia. Anthropometric parameters such as BMI Z-score, waist circumference and waist/height ratio were evaluated in 266 school children and teenagers. A questionnaire with socio-demographic, clinical and lifestyle characteristics and the KIDMED were applied to learn about nutritional aspects. A total of 102 students (38⋅3 %) were classified as having altered nutritional status, being 39 (14⋅7 %) classified as overweight and 36 (13⋅5 %) with obesity. The prevalence of high adherence to the Mediterranean diet was 12 %, 95 % CI (0⋅08, 0⋅16). Overweight was more prevalent in women (26/39, 66⋅7 %; P = 0⋅0439), and obesity was discreetly more frequent in men (19/36, 52⋅7 %; P = 0⋅7193). We observed a worrying nutritional, dietary and behavioural situation in the children and teenagers studied during the confinement associated with the COVID-19 pandemic. This unveils the need to establish strategies and/or public policies in our town that help to promote an adequate biopsychosocial development of the paediatric patient and their family group.

Nitro-fatty acids (NO2-FAs) are novel molecules resulting from the interaction of unsaturated fatty acids and nitric oxide (NO) or NO-related molecules. In plants, it has recently been described that NO2-FAs trigger an antioxidant and a defence response against stressful situations. Among the properties of NO2-FAs highlight the ability to release NO therefore modulating specific protein targets through post-translational modifications (NO-PTMs). Thus, based on the capacity of NO2-FAs to act as physiological NO donors and using high-accuracy mass-spectrometric approaches, herein, we show that endogenous nitro-linolenic acid (NO2-Ln) can modulate S-nitrosoglutathione (GSNO) biosynthesis in Arabidopsis. The incubation of NO2-Ln with GSH was analyzed by LC-MS/MS and the in vitro synthesis of GSNO was noted. The in vivo confirmation of this behavior was carried out by incubating Arabidopsis plants with 15N-labeled NO2-Ln throughout the roots, and 15N-labeled GSNO (GS15NO) was detected in the leaves. With the aim to go in depth in the relation of NO2-FA and GSNO in plants, Arabidopsis alkenal reductase mutants (aer mutants) which modulate NO2-FAs levels were used. Our results constitute the first evidence of the modulation of a key NO biological reservoir in plants (GSNO) by these novel NO2-FAs, increasing knowledge about S-nitrosothiols and GSNO-signaling pathways in plants.
