RESUMO
El deterioro del medio ambiente ha acelerado el cambio climático (CC) afectando mútiples escenarios, el aumento de la temperatura ha conllevado a la proliferación de diversas enfermedades trasmitidas por vectores de importancia a nivel de salud pública. Como objetivo, se propuso determinar la cultura ecosaludable ante el cambio climático en estudiantes del Área Ciencias de la Educación, Universidad Nacional Experimental Rómulo Gallegos (UNERG), Calabozo, Venezuela 2022. El estudio fue cuantitativo exploratorio no experimental de corte transversal con una muestra de 180 estudiantes. Para la recolección de datos se aplicó el Cuestionario de Dimensiones Ambientales (CDA) compuesto de 75 ítems distribuidos en tres dimensiones; conocimientos, actitudes, emociones y comportamientos. El análisis de los datos fue por estadística descriptiva con porcentajes a través del programa Epidat 3.0. Como resultado, 63% indicó la importancia atribuida de los elementos de ecosalud afectados sobre el agua y 55% al calentamiento global. No obstante, solo 12% indicó la educación como un elemento de ecosalud afectado por el cambio climático, así mismo, en la dimensión de conocimientos se encontró 54,50% a CSN, 6,50% a CPR y 39,50% a CEA, en la dimensión de actitudes y emociones se encontró 55,50% a la subcategoria TD, 44,00% a CVA y 36,50% a E, finalmente, en la dimensión de comportamiento, se evidenció 36,50% a la subategoria de PC, 29,00% a IC y 20,00% a PI. Se debe evitar el daño ambiental a través del cambio de comportamiento individual que debe ser enseñado desde los recintos universitarios(AU)
The deterioration of the environment has accelerated climate change (CC) affecting multiple scenarios, the increase in temperature has led to the proliferation of various diseases transmitted by vectors of importance at the public health level. As an objective, it was proposed to determine the eco-healthy culture in the face of climate change in students of the Educational Sciences Area, Rómulo Gallegos National Experimental University (UNERG), Calabozo, Venezuela 2022. The study was quantitative, exploratory, non-experimental, cross-sectional with a sample of 180 students. For data collection, the Environmental Dimensions Questionnaire (CDA) was applied, consisting of 75 items distributed in three dimensions; knowledge, attitudes and emotions and behaviors. Data analysis was by descriptive statistics with percentages through the Epidat 3.0 program. As a result, 63% indicated the importance attributed to the affected ecohealth elements on water and 55% on global warming. However, only 12% indicated education as an element of ecohealth affected by climate change, likewise, in the knowledge dimension, 54.50% were found to CSN, 6.50% to CPR and 39.50% to CEA, in the dimension of attitudes and emotions, 55.50% were found in the TD subcategory, 44.00% in CVA and 36.50% in E, finally, in the behavior dimension, 36.50% were found in the subcategory of PC, 29.00% to IC and 20.00% to PI. Environmental damage must be avoided through individual behavior change that must be taught from university campuses(AU)

La gestión ambiental universitaria es un proceso que comprende un conjunto de elementos para el manejo y solución de los problemas ambientales dentro de la instalación educativa. El objetivo del estudio fue identificar la relación existente entre la gestión ambiental universitaria y la actitud frente al cambio climático en docentes. La investigación se enmarcó dentro del enfoque cuantitativo, de tipo descriptivo correlacional, diseño no experimental de corte trasversal. Se tomó como muestra 58 docentes de las carreras educación integral y educación mención computación, de una universidad pública venezolana, a quienes se les aplicó dos cuestionarios administrados vía online. En los resultados se encontró que existe una moderada y baja gestión ambiental universitaria, asimismo, una moderada y baja actitud frente al cambio climático en los docentes de ambas carreras, siendo la actitud predominante la conductual, seguida de la afectiva y por última la cognitiva. Se identificó la relación de las variables, gestión ambiental universitaria y actitud frente al cambio climático debido a que estadísticamente se encuentran relacionadas. Se concluye que existe la necesidad generar una gestión ambiental universitaria para cambiar actitudes y responder de manera oportuna a los cambios climáticos presentes, generando una nueva cultura ambiental en los actores educativos(AU)
University environmental management is a process that includes a set of elements for the management and solution of environmental problems within the educational facility. The objective of the study was to identify the relationship between university environmental management and the attitude towards climate change in teachers. The research was framed within the quantitative approach, correlational descriptive type, non-experimental cross-sectional design. A sample was taken of 58 teachers from the comprehensive education and computer education majors, from a Venezuelan public university, to whom two questionnaires administered online were applied. In the results, it was found that there is a moderate and low university environmental management, as well as a moderate and low attitude towards climate change in the teachers of both careers, the predominant attitude being behavioral, followed by affective and finally cognitive. The relationship of the variables, university environmental management and attitude towards climate change was identified because they are statistically related. It is concluded that there is a need to generate university environmental management to change attitudes and respond in a timely manner to current climate changes, generating a new environmental culture in educational actors(AU)

Edible and medicinal mushrooms contain bioactive compounds with promising effects on several cardiovascular risk biomarkers. However, strains of Ganoderma lucidum of Mexican origin have not yet been studied. Standardized extracts of G. lucidum (Gl) were given to C57BL/6 mice fed a high-cholesterol diet compared with the drug simvastatin. The effects of the extracts on serum biochemical parameters, liver lipid content, cholesterol metabolism, and the composition of gut microbiota were assessed. Acetylsalicylic acid (10 mM) added to the cultivation substrate modulated properties of Gl extracts obtained from mature basidiomata. Compared to the high-cholesterol diet group, the consumption of Gl extracts significantly reduced total serum cholesterol (by 19.2% to 27.1%), LDL-C (by 4.5% to 35.1%), triglyceride concentration (by 16.3% to 46.6%), hepatic cholesterol (by 28.7% to 52%) and hepatic triglycerides (by 43.8% to 56.6%). These effects were associated with a significant reduction in the expression of lipogenic genes (Hmgcr, Srebp1c, Fasn, and Acaca) and genes involved in reverse cholesterol transport (Abcg5 and Abcg8), as well as an increase in Ldlr gene expression in the liver. No significant changes were observed in the gene expression of Srebp2, Abca1 or Cyp7a1. In several cases, Gl-1 or Gl-2 extracts showed better effects on lipid metabolism than the drug simvastatin. A proposed mechanism of action for the reduction in cholesterol levels is mediated by α-glucans and ß-glucans from Gl, which promoted decreased absorption of cholesterol in the gut, as well as greater excretion of fecal bile acids and cholesterol. The prebiotic effects of Gl-1 and Gl-2 extracts modulated the composition of gut microbiota and produced an increase in the Lactobacillaceae family and Lactobacillus genus level compared to the control group, high-cholesterol diet group and group supplemented with simvastatin. Mexican genetic resources of Gl represent a new source of bioactive compounds showing hypocholesterolemic properties and prebiotic effects.
