From the perspective of unesco, which highlights education as a pillar for peace, inclusion, and sustainability, Service-Learning (sll) is presented as an educational methodology that integrates academic learning with community participation, promoting critical and engaged citizenship through the formation of bonds and networks of solidarity and collaborative work. This article analyzes the genesis of sll, detailing its methodology and its inherent link with citizenship education, and explores its global implementation, highlighting the work of school, university, and civil society networks in diverse contexts. The article also reflects on the Mexican Service-Learning Network, examining its structure, achievements, and challenges ahead to consolidate its impact within the educational policy contained in the New Mexican School (nem) project. Finally, a critical reflection is offered on the role of this network in promoting active citizenship, considering its contributions and areas for improvement. We conclude that SL fosters meaningful learning and strengthens the social fabric, paving the way for a more just and equitable society. Its consolidation requires a shared commitment across institutions and communities

Despite the richness of theoretical debates on global citizenship, especially in the global north, there remains a notable lack of studies from the global south that promote experiences of Global Citizenship Education (gce) through critical-decolonial approaches and participa-tory methodological proposals. This article seeks to address the following question: How can we promote gce through a Participatory Action Research (par) experience in a Latin American university? The par experience discussed in this article took place in 2023 and was developed using a reflective dialogic pedagogy in a class aimed at student teachers. The par experience included the identifying global/local problems, researching these issues, constructing collective actions and conducting semi-structured interviews with participants. The findings indicate that the par experience enhanced students’ critical thinking, sense of global belonging, and empathy with others. The article concludes by identifying challenges for future gce experiences in the university context, emphasizing the importance of more closely connecting gce efforts with social, community and political processes.

What is the relationship between academic and official discourses on citizenship education at the high school level? In which spaces, and through what means, are certain practices of citizenship shaped among Mexican students in upper secondary education? This paper seeks to address these questions by analyzing the interplay between these discourses and examining student practices. Our aim is to evaluate research conducted during the early decades of the twenty-first century while presenting data gathered through a question-naire administered in four Mexican states. This questionnaire explored some participatory behaviors related to citizenship. Our findings suggest that there is a certain conceptual tension between academic and official discourses on citizenship education. However, we also observe increasing convergence between the two, particularly following the implemen-tation of the 2019 high school reform; also, we highlight the tendency to overlook student practices associated with citizenship learning, both within and beyond school settings.

In the present research, the objective was to obtain the reliability and evidence of validity of the Abbreviated Multidimensional Perfectionism Scale in the Mexican population. To achieve this objective, an instrumental study was carried out through the application of the Abbreviated Multidimensional Perfectionism Scale to a population of 539 participants from the state of Durango, in Mexico. The results indicate an adequate level of reliability and a three-factor structure that coincides with the original and was derived from the Exploratory Factor Analysis; This structure, when subjected to Confirmatory Factor Analysis, shows eight adequate fit indices, with the exception of the ECVI, PNFI and p values of the chi square, which would generally indicate an adequate fit of the model. It is concluded that further studies are needed in this regard.

In the Neotropics, butterfly diversity is threatened by the loss and transformation of natural habitats, mainly due to deforestation and the expansion of human activities. Diurnal butterflies, recognized as bioindicators of habitat quality, allow for the evaluation of ecosystem conditions. The objective of this article was to determine the diversity of diurnal butterflies in the RNCE Uruki–El Manantial, located in the municipality of Florencia, Caquetá, to provide useful information for their conservation. Sampling was conducted over 15 days in December 2022, across 10 stations. At each station, a Van Someren-Rydon trap was installed, alternately baited with fermented fruit and decomposing fish, and complemented by active searching with an entomological net. A total of 1,210 specimens were collected, belonging to six families, 17 subfamilies, and 95 species. The family Nymphalidae was the most diverse (47.3%). Species richness varied with vegetation cover, being higher at forest edges and pastures, whereas conserved forests harbored a more specialized composition. A total of 54.7% of the species recorded were rare or uncommon. The most representative were Hermeuptychia hermes (28.4%), Eurema daira, and Anartia jatrophae (8.5% each), associated with habitats under anthropogenic pressure. Additionally, species indicative of well-preserved environments were recorded, including Callicore cynosura, Kolana ligurina, Bungalotis milleri, Morpho achilles, and Archaeoprepona demophon (7%). These results highlight the importance of implementing conservation strategies that integrate the biocultural and ecotourism value of butterflies in the Colombian Amazon.

Occupational exposure to BTX compounds (benzene, toluene, and xylene) continues to pose significant health risks, especially in industrial settings where these solvents are widely used in the manufacturing of rubber, paints, and plastics. Benzene, classified as a Group one carcinogen by the IARC, has been linked to severe genotoxic effects, including DNA damage in bone marrow cells, increasing the risk of leukemia and aplastic anemia. Toluene and xylene, although less toxic, also present significant health concerns, particularly affecting vital organs and the central nervous system. This narrative review examines key biomarkers used to assess genotoxic damage in exposed workers, such as 8-oxoguanine, micronucleus assays, and gene expression analysis. Biomonitoring is emphasized as a critical strategy for early disease detection and the development of effective preventive measures. The review presents the strengths and limitations of these biomarkers and highlights their potential role in shaping future occupational health monitoring programs. By providing a comprehensive overview of current research, this work aims to support the implementation of policies that protect workers from hazardous chemical exposure and improve overall workplace safety.

The genus Phlebovirus is considered a medically important group of viruses due to the pathogenic behavior of some species. In the Americas, several species of this genus have been identified, most of which are found in Panamá. However, the lack of knowledge about the circulation of phleboviruses in Colombia led us to ask several questions, including the distribution of this pathogen in the Americas, especially in Caribbean coastal areas where ideal conditions for phlebovirus vectors exist. Here, we report the first detection of the genus Phlebovirus in phlebotomine sandfly communities from the Caribbean coast of Colombia. Sandflies were collected and pooled for ribonucleic acid (RNA) extraction and retrotranscription, all pools were tested for 18S ribosomal RNA and screened for phleboviruses by nested reverse transcription-polymerase chain reaction (RT-PCR). Positive products for the RNA-dependent RNA polymerase (RdRp) detection were sequenced. Four pools of 58 were positive for viruses belonging to the Punta Toro complex, Aguacate complex, Old-World viruses, and one related to sloth phleboviruses. This is the first evidence of phleboviruses in the Caribbean region of Colombia, especially of species related to the Punta Toro and Aguacate complex.

Glioblastoma Multiforme (GBM) represents tumors that develop in the Central Nervous System (CNS) with the highest malignancy, incidence and prevalence. Flavonoid therapy has been gaining strength as an alternative adjuvant that counteracts the appearance and development of various cancers, including GBM. The objective of this review is to analyze the use of flavonoids in GBM therapy in a ten-year window (2013-2023). Fifty-one articles were reviewed, including original articles and bibliographic reviews. Flavonoids have been tested in different GBM in vitro models, decreasing proliferation and angiogenesis, activating signaling pathways and redirecting cell activity to alternative pathways that promote apoptosis and cell repair.

High levels of species diversity and endemism in developing countries contrast with a dramatic expansion of human populations and urban development. This poses a challenge for wildlife and their ability to adapt to transformed and fragmented habitats. In the Neotropics, tamarins and marmosets (Primates: Callitrichidae) have established populations in urbanized areas, including the White-footed tamarin in north-western Colombia, where it is prone to metabolic syndrome presumably due to nutritional issues and reduced physical activity. We conducted an exploratory analysis of habitat use and activity budget of a group of the White-footed tamarin established in an isolated forest patch in Medellín, Colombia over a 12-month period. We applied multiple linear regressions to assess 1) the seasonal variation of diet and 2) the role of landscape features on the use of the available habitat. Resting was the most dominant behavior. The diet comprised a range of animal and plant items as well as a smaller proportion of anthropogenic food. The diet diversity showed an inverse relationship with the within-month humidity variation, indicating an adaptation to seasonal changes. The use of available area was associated with tree density and abundance of key plant species that are either consumed or used as part of corridors. Our results suggest that seasonal plasticity and generalist diet habits may be favored in species adapted to urbanized areas, but food oversupply may lead to sedentarism and compromise the health of urban fauna. Strategic planting of key tree species that provide food sources and facilitate dispersal is recommended.
