La literatura científica constata que el ocio intergeneracional reporta múltiples beneficios, en concreto, a los más mayores, a quienes proporciona vitalidad, motivación, bienestar emocional e ilusión, lo que apunta a que estas experiencias poseen el potencial de incrementar los niveles de satisfacción en el colectivo de personas mayores. El objetivo de este estudio fue examinar la satisfacción percibida por los abuelos con el ocio que comparten con sus nietos adolescentes, y vincularla con la tipología de actividades. Se utilizó un cuestionario ad hoc administrado a 91 abuelos, y se llevó a cabo un estudio descriptivo y un análisis inferencial de los datos. El nivel de satisfacción transmitido con respecto al ocio compartido es, en general, muy elevado, pues la práctica totalidad de los abuelos presenta un alto grado de satisfacción con el ocio que comparten con sus nietos adolescentes, siendo muy escasas las diferencias en la satisfacción en función de las distintas actividades de ocio. Existen algunas diferencias sobre la forma en la que les gustaría compartir ocio en un futuro con los adolescentes. En general, quienes comparten ocio cultural estarían más dispuestos a cambiar la forma en la que comparten el ocio con sus nietos, pues se sienten menos satisfechos con el disfrute del ocio mediante entornos culturales. Sin embargo, escuchar música se descuelga de las actividades culturales al relacionarse con una satisfacción significativamente superior. Destacan tres actividades culturales (escuchar música, ir al cine y a museos, galerías y exposiciones) por asociarse con una mayor disposición a seguir practicando ocio junto a sus nietos tal y como lo vienen haciendo. Por otro lado, en general, los abuelos que comparten experiencias ambientales y ecológicas, así como actividades festivas y celebraciones, manifiestan claramente una mayor disposición a repetir la forma en la que compartirían su ocio en el futuro que quienes no comparten este tipo de actividades, especialmente a la hora de viajar, ir de excursión, cuidar plantas, salir a tomar algo e ir a fiestas tradicionales. Las conclusiones de este estudio ayudan a la comprensión de la etapa previa a la juventud, ofreciendo claves susceptibles de optimizar el bienestar personal e intergeneracional. Se discute si la excepcionalidad de la situación que sobrevino por el COVID-19, ha provocado alteraciones importantes en la relación abuelos-nietos, con la consiguiente necesidad de continuar esta línea de investigación.
A vueltas con Suárez, Locke y el concepto moderno de propiedad privada.
Authors: Utrera García Juan Carlos 
Published: December 2024

Este trabajo realiza una revisión crítica de la influencia de la doctrina de Francisco Suárez acerca del dominio sobre la teoría de la propiedad privada en John Locke. A fin de explicitar las claves del pensamiento del jesuita, se pone de manifiesto su esencial continuidad con la tradición escolástica y con los fundamentos de su reflexión económica, para a continuación mostrar hasta qué punto Locke realiza una utilización parcial y sesgada de la obra de Suárez. De ahí se concluye que, pese a las coincidencias incidentales señaladas en recientes estudios, sendos autores conciben la propiedad privada de manera esencialmente antitética y responden a un proyecto distinto de modernidad.
Canticum canticorum, de la interpetación literal y espiritual de Fray Luis de León a la traducción pictórica de Tomás Luis de Victoria
Authors: Vela González Marta 
Published: December 2024

El Cantar de los Cantares suscitó un gran interés artístico durante la Contrarreforma en España, tras el Concilio de Trento. Las interpretaciones literal y spiritual Fray Luis de León (1527-1591) –que le acarrearon prisión entre 1572 y 1576– representan su voluntad de explicar el texto salomónico, mientras que la obra musical de Tomás Luis de Victoria (1548?-1611) contiene también numerosas alusiones, donde se observa una intensa fusión de distintas ramas artísticas. De este modo, las imágenes explicadas por Fray Luis encuentran su réplica en distintos motetes de Victoria, hasta cinco, entre 1572 y 1583, punto de encuentro entre texto, sonido e imagen. @font-face {font-family:SimSun; panose-1:2 1 6 0 3 1 1 1 1 1; mso-font-alt:宋体; mso-font-charset:134; mso-generic-font-family:auto; mso-font-pitch:variable; mso-font-signature:3 680460288 22 0 262145 0;}@font-face {font-family:"Cambria Math"; panose-1:2 4 5 3 5 4 6 3 2 4; mso-font-charset:0; mso-generic-font-family:roman; mso-font-pitch:variable; mso-font-signature:-536870145 1107305727 0 0 415 0;}@font-face {font-family:"Lucida Sans"; panose-1:2 11 6 2 3 5 4 2 2 4; mso-font-charset:77; mso-generic-font-family:swiss; mso-font-pitch:variable; mso-font-signature:3 0 0 0 1 0;}@font-face {font-family:"\@SimSun"; panose-1:2 1 6 0 3 1 1 1 1 1; mso-font-charset:134; mso-generic-font-family:auto; mso-font-pitch:variable; mso-font-signature:3 680460288 22 0 262145 0;}p.MsoNormal, li.MsoNormal, div.MsoNormal {mso-style-unhide:no; mso-style-qformat:yes; mso-style-parent:""; margin:0cm; mso-pagination:none; mso-hyphenate:none; text-autospace:ideograph-other; font-size:12.0pt; font-family:"Times New Roman",serif; mso-fareast-font-family:SimSun; mso-bidi-font-family:"Lucida Sans"; mso-font-kerning:1.5pt; mso-fareast-language:ZH-CN; mso-bidi-language:HI;}p.Standard, li.Standard, div.Standard {mso-style-name:Standard; mso-style-unhide:no; mso-style-parent:""; margin:0cm; mso-pagination:none; mso-hyphenate:none; text-autospace:ideograph-other; font-size:12.0pt; font-family:"Times New Roman",serif; mso-fareast-font-family:SimSun; mso-bidi-font-family:"Lucida Sans"; mso-font-kerning:1.5pt; mso-fareast-language:ZH-CN; mso-bidi-language:HI;}.MsoChpDefault {mso-style-type:export-only; mso-default-props:yes; mso-fareast-font-family:SimSun; mso-bidi-font-family:"Lucida Sans"; mso-font-kerning:1.5pt; mso-fareast-language:ZH-CN; mso-bidi-language:HI;}.MsoPapDefault {mso-style-type:export-only; mso-pagination:none; mso-hyphenate:none; text-autospace:ideograph-other;}div.WordSection1 {page:WordSection1;}

Exploring the association between age-related macular degeneration and 25-hydroxy vitamin D level: A causal connection
Authors: Jabeen Asma , Qayum Shazia 
Published: December 2024

Age-related macular degeneration, or AMD, is a common cause of permanent loss of vision that mostly affects elderly population. Complex interplay between genetic and environmental variables are part of the pathogenesis. Vitamin D, namely 25-hydroxyvitamin D [25(OH)D], has drawn interest because of its anti-inflammatory and protective characteristics, which may contribute to AMD. Given the current situation of its increasing incidence and the possible significance of vitamin D for retinal health, the purpose of this research was to examine the relationship between blood 25(OH) D levels and AMD severity in the Indian population. : As per the criteria outlined in Age-Related Eye Disease Study (AREDS), 112 patients in a cohort study were divided into three AMD severity groups at the Eye Department of ASCOMS Medical College in India. Clinical evaluations, the gathering of demographic data, and biochemical studies of serum 25(OH) D levels were carried out. Descriptive statistics, correlation analyses, logistic regression, subgroup analysis, and comparisons with other research conducted internationally were among the statistical analyses performed. The study showed a substantial correlation between serum 25(OH) D levels and the severity of AMD compared to early-stage instances (Group 1: mean = 30.5 ng/mL, SD = 4.1), patients with advanced-stage AMD (Group 3) had lower 25(OH) D levels (mean = 25.3 ng/mL, SD = 4.7). In line with previous research, two important risk factors for AMD were found: a history of smoking and a family history of the disease.: In summary, this study provides important new information on the relationship between the severity of AMD and serum 25(OH)D levels in the Indian population. This is consistent with the data that is now available, which indicates that the retina and retinal pigment epithelium have vitamin D receptors. Despite being observational, the results encourage further research into the underlying processes and the causal link. The risk factors that have been found highlight how crucial it is for public health efforts to focus on modifiable variables like smoking. In summary, this study establishes the groundwork for further investigation, which might lead to the development of innovative approaches for managing and preventing AMD.

Diabetes mellitus causes several ophthalmic complications including retinopathy, cataract, and damage to the anterior chamber of the eye including various layers of the cornea. To compare endothelial cell loss after phacoemulsification surgery for cataracts among diabetics and non-diabetic patients. A single-centre, hospital-based, prospective, comparative, 1:1 observational study enrolling participants a total of 200 participants were enrolled (100 diabetic and non-diabetic) and were followed up from the preoperative period to 3 months after surgery. The data pertaining to endothelial cell density, coefficient of variance, endothelial cell hexagonality and central corneal thickness were recorded using specular microscopy before, 1-, 7-, 30-, and 90 days after cataract surgery. There was a significant difference (p&#60;0.05) in the endothelial cell density, coefficient of variance, endothelial cell hexagonality, and central corneal thickness among the diabetic and non-diabetic patients at each follow-up visit after surgery. The ECD was comparatively lowest among the participants with &#62;10 years of diabetes and highest among patients with &#60; 5 years of diabetes. The percentage change in ECD on days 1-, 7-, 30-, and 90 days of cataract surgery among the diabetic patients was 8.8%, 11.7%, 12.9% and 18.7%, respectively. The mean ECH among the patients with &#60; 5 years, 5-10 years, and &#62; 10 years of diabetes was 65.7%, 62.5% and 57.5%, respectively. In comparison to non-diabetic patients, there was a considerable loss of endothelial cell function among diabetic individuals following cataract surgery. Furthermore, a slower and poorer healing response was seen in patients with diabetes.

Published: December 2024

Lipemia retinalis is a condition where the retinal blood vessels appear salmon pink to creamy white in color. It typically happens in individuals with either primary or secondary hyperlipidemia. This distinct appearance is caused by the presence of circulating chylomicrons in the blood.A 56-year-old female presented with dense, yellowish hypopigmented patches on the upper eyelids of both eyes. She was a known case of hypertension and hyperlipidaemia on irregular medication. The examination revealed lipemia retinalis with creamy coloured vessels. The patient was started on lipid lowering drugs.

O Brasil é um país de dimensões continentais. A sua superfície é cortada por dois paralelos dos principais círculos de latitude: o Equador e o Trópico de Capricórnio. Neste ambiente, educadores têm reproduzido o clássico Experimento de Eratóstenes que permite estimar o valor da circunferência do planeta Terra. Há alguns anos a ação mundial faz parte do projeto organizado pelo Research and Development Department of Ellinogermaniki Agogi - Grécia, com o apoio da International Astronomical Union (IAU). Nesse sentido, a interação entre educadores de ciências de quatro instituições localizadas em diferentes regiões do Brasil permitiu reproduzir, simultaneamente, o Experimento de Eratóstenes com toda a atividade experimental transmitida de forma online com o uso da plataforma YouTube, e participação de docentes e estudantes visando contribuir o aprendizado e com o propósito de agregar mais conhecimento junto a comunidade. Os dados foram coletados nas cidades de Macapá (AP), Imperatriz (MA), Jataí (GO) e Itapetininga (SP) cujas longitudes são muito próximas. O Experimento foi desenvolvido nos anos de 2020 e 2022, durante o solstício de verão e equinócio da primavera no Hemisfério Sul. Os resultados obtidos com este trabalho de engajamento virtual são discutidos em detalhes.

Este artigo descreve a criação e os objetivos da animação intitulada “Você sabe o que é limpo e sujo? Nós vamos te contar: percepções das crianças pequenas em uma visão antropológica” como parte integrante do projeto de mestrado profissional do Programa de Pós-Graduação em ensino das Ciências da UNIGRANRIO. A animação tem como propósito principal abordar o tema higiene a partir de uma perspectiva de Educação Antropológica, para compreender como as crianças pequenas (3 e 4 anos de idade) entendem o conceito de limpo e sujo em um contexto coletivo educativo, partindo do princípio de que o desconhecimento desses conceitos impactam de forma concreta na saúde de seus corpos, possibilitando o surgimento de novas doenças. A criação da animação correlaciona o discurso coletivo após coleta e análise dos dados de pesquisa atrelados aos conteúdos considerados relevantes para o coletivo das profissionais da unidade infantil, lócus da pesquisa. A animação poderá ser incorporada ao planejamento pedagógico nas unidades infantis de todo o país como ponto de partida para desenvolverem suas próprias animações a respeito dos conceitos de limpo e sujo imbuídas das percepções de suas crianças pequenas. As educadoras poderão agregar novas descobertas na busca por essas percepções e refletir a respeito de suas estratégias pedagógicas. Acredita-se que por meio deste movimento de Educação Antropológica em um movimento inverso a projetos assistencialistas na educação infantil quando se fala em higiene, haverá a facilidade de compreensão dos conceitos também pela animação produzida e linguagem direcionada às crianças pequenas. A animação, apesar de se encontrar em fase prototípica, tem repercutido de maneira positiva entre as profissionais da Educação participantes da pesquisa que colaboraram para a idealização desse Produto Educacional. O projeto tem se revelado uma evocação convidativa para outros pares caminharem rumo à direção de práticas significativas e libertadoras na Educação Infantil.

Introduction: As individual grow older, the likelihood of developing cardiovascular diseases increases significantly. Currently, high-intensity interval training (HIIT) is regarded as a strategy for exercise to improve heart disease. Consequently, the aim of this research was to investigate the impact of eight weeks of HIIT on the levels of PINK1 and PARKIN proteins in the left ventricle of aged rats.
Methods: The present research was of an experimental type and involved twelve male rats, each 20 months old, with an average weight of 400 ± 30 grams. The rats were randomly divided into HIIT and control groups (each group had 6 rats).
The HIIT program consisted of high-intensity bouts of 85-95% of maximum speed (m/min) and active rest periods with an intensity of 40-55% of maximum speed (m/min) during each weekly session. Following a 48-hour period post the most recent training session, the rats were subjected to anaesthesia through the administration of Ketamine and Xylazine. Subsequently, the left ventricle of the heart was excised, and the various parameters were measured utilizing the western blot laboratory technique. Data were analysed using the Shapiro-Wilk test and independent t-test conducted within SPSS16. A significance threshold of P≥0.05 was considered for this analysis.
Results: Eight weeks of HIIT caused a significant increase in PINK1 (P=0.02) and PARKIN (P=0.004) protein levels in the left ventricle of aged rats, in comparison to the control group.
Conclusion: It seems that HIIT may influence the quality of mitochondria within the left ventricle of the hearts of aged rats, indicating potential implications for health-related applications.

Introduction: Given the widespread issue of methamphetamine addiction and its damaging effects, coupled with the crucial role of the kidneys in maintaining bodily equilibrium, we chose to undertake this study.
Methods: Forty rats were randomly divided into five equal groups: control, methamphetamine, methamphetamine with exercise, methamphetamine with berberine hydrochloride, and methamphetamine with both exercise and berberine hydrochloride. The administration of methamphetamine at a dose of 15 mg/kg intraperitoneally for a duration of 4 days every 12 hours and berberine hydrochloride 100 mg/kg intraperitoneally for a duration of 4 weeks daily has been conducted. Aerobic exercise was performed in the form of running on a rodent treadmill for 8 weeks with moderate intensity. Twenty-four hours following the final exercise and administration of berberine hydrochloride, kidney tissue was extracted and examined under a light microscope, in accordance with the ethics committee's guidelines.
Results: In the methamphetamine group, the glomerulus diameter decreased, hyperemia and tissue disorganization occurred, and the cells of the proximal and distal convoluted tubules were atrophied. In the methamphetamine group, with exercise, there was a decrease in diameter in some glomeruli and changes in hyperemia and an increase in the diameter of blood vessels. In the group treated with methamphetamine and berberine hydrochloride, there was a noted shrinkage of glomeruli and an increase in urinary space. In the group receiving methamphetamine, exercise, and berberine hydrochloride, the quantity and size of glomeruli as well as the spaces between them, were normal and without irregularities.
Conclusion: This research demonstrated that both aerobic exercise and berberine hydrochloride can mitigate the damaging histopathological impacts of methamphetamine on the kidney, indicating that their simultaneous use may offer enhanced protective benefits. effect
The Effect of Mach and Reynolds Numbers on the Aerodynamic Characteristics of the Nozzle Cascade of a Gas Turbine
Authors: Lapuzin Alexander , Subotovich Valery , Yudin Yuriy , Naumenko Svetlana 
Published: December 2024

The data of experimental studies of a circular nozzle cascade for a small-sized gas turbine with a medium ratio of the diameter to the blade height as part of a turbine stage, as well as in conditions of joint operation with a radial diffuser have been presented. In the presence of an impeller, the Mach number varied in the range of 0.3 to 0.85, and in static conditions it varied in the range of 0.3 to 1.4. The flow rate coefficient was determined by the integral method using drains, and the loss coefficients and averaged flow angles were determined based on the data of detailed measurements of the flow parameters behind the cascade using pneumometric probes. The aerodynamic efficiency of the nozzle cascade is at a very high level and in the calculated transonic mode the kinetic energy loss coefficient is 0.052, and the total loss coefficient is 0.09. For modes, where the Mach number is equal to 0.6, a very strong effect of the boundary conditions behind the nozzle cascade on its aerodynamic characteristics is recorded and it is indicative of the drawbacks of experiments without an impeller. It is established that the impeller can be abandoned if the Mach number exceeds 0.85. It is also established that for a Mach number above 1.15, the Reynolds number of 10,5×105 is self-similar for the flow rate coefficient. When the Mach number is increased to 1.25, the nozzle cascade is completely closed, and the flow coefficient in the self-similarity zone reaches a maximum in terms of the Reynolds number. For the thermal calculations of the stage, the averaged angle of the flow exit from the nozzle cascade and its total loss coefficient that takes into account not only kinetic energy losses, but also kinematic losses should be used.
