Teacher training in the state of Chihuahua: Between the health challenge and teacher resilience

Evangelina Cervantes Holguín Pavel Roel Gutiérrez Sandoval Cely Celene Ronquillo Chávez (2023, [Artículo, Artículo])

The article proposes to recover the response of the Teacher Training and Updating Institutions in the state of Chihuahua regarding the various challenges imposed by the Coronavirus Disease (COVID-19). The qualitative exercise analyzes the experience of 10 institutions based on the voice of their students, teachers, and principals regarding changes in academic, administrative, and organizational processes. It is concluded that the pandemic has affected each institution in different ways and with diverse intensity. Despite the achievements, the experience analyzed reveals the relative success of the using virtual platforms in the face of three basic conditions: connectivity, technological competencies, and socio-emotional skills of the teaching staff. It highlights the importance of implementing tutoring, resilience, or awareness actions of teachers and students' needs, feelings, and sufferings. It is opportune to recover the experiences of other institutions and to question especially students, thesis students and graduates.

THE RIGHT TO THE CITY AND URBAN-RURAL LINKAGES. COMMUNITY PARTICIPATION IN THE METROPOLITAN AREA OF TUXTLA GUTIERREZ, CHIAPAS.

Briseida Corzo Rivera Gabriel Castañeda Nolasco (2023, [Artículo, Artículo])

Access to water is a common struggle of the communities in the state of Chiapas, with the effects of urban expansion these struggles increase and with them the challenges that these populations already face, having a greater impact on the rural environment. The struggles to satisfy this basic need are a factor that has triggered processes that promote community participation. Based on a qualitative analysis, this paper compares two existing forms of participation in the rural communities of the Metropolitan Area of Tuxtla Gutierrez that allow the population to manage actions to improve their quality of life. The objective is to analyze how these processes promote or restrict the empowerment of the community and allow progress, not only in the population's access to water, but also in the construction of the right to the city. From the urban-rural linkages, the right to the city is discussed beyond the city, addressing other territories. The study identifies factors that show changes in the participation of the populations and strengthen the community, as well as factors in the relationships of the community and of the community with other actors that limit the scope of the processes.

Estudio de biomarcadores metabólicos en la piel relacionados con el envejecimiento en una población del noroeste de México

Study of metabolic biomarkers in the skin related to aging in a population from northwest Mexico

JHORDAN OJEDA GONZALEZ (2023, [Tesis de maestría])

La piel, siendo el órgano más grande, es fácilmente accesible para la obtención de muestras no invasivas. Esto convierte a la piel en una valiosa fuente de datos biológicos para la evaluación del estado de salud de los individuos. Sin embargo, la edad desempeña un papel central en casi todos los procesos humanos, y si no se tiene en cuenta adecuadamente, podría introducir sesgos al evaluar la condición de la piel. Por lo tanto, comprender cómo la edad afecta el metabolismo de la piel es crucial para crear perfiles del tipo y abundancia de metabolitos en diferentes etapas del desarrollo humano. Este estudio tuvo como objetivo identificar las diferencias metabólicas en la piel entre sujetos mexicanos de diferentes grupos de edad. Para lograrlo, se recolectaron muestras superficiales de piel (obtenidas mediante hisopos de algodón) de 75 pacientes con edades comprendidas entre 3 y 74 años. Los datos metabolómicos se obtuvieron a través de cromatografía líquida-espectrometría de masas en tándem (LC-MS2), mientras que la identificación de metabolitos y los análisis estadísticos se realizaron utilizando programas informáticos exhaustivos y complementarios (GNPS, Sirius, MZmine, Metaboanalyst, entre otros). Después de un extenso uso de herramientas quimioinformáticas, se identificaron de manera putativa 2,193 metabolitos (peptídicos y no peptídicos) de diversas clases químicas, como ácidos carboxílicos y sus derivados, acilos grasos, benceno y sus derivados sustituidos, compuestos organooxigenados, entre otros. Algunos metabolitos se cree que son sintetizados por bacterias. A través de un análisis de regresión logística con ajuste de covariables, identificamos varios metabolitos asociados positiva y negativamente con la edad, algunos de los cuales eran específicos para cada género. Los hallazgos de este trabajo incluyen la identificación de potenciales biomarcadores del envejecimiento como ciclo(Leu-Pro), destiobiotina, entre muchos otros, y también se proponen las principales clases químicas afectadas, como son azoles, diazinas y polipéptidos. En general, hemos contribuido a iluminar el panorama químico de la piel humana en una población mexicana, sugiriendo metabolitos que podrían funcionar potencialmente como biomarcadores de envejecimiento y enfermedades. No obstante, para validar nuestros hallazgos, se requieren estudios más amplios con grupos étnicos diversos y tamaños de muestra más grandes.

The skin, being the largest organ, is readily accessible for non-invasive sampling, making it a valuable source of biological data that could facilitate the assessment of individuals health status. However, age exerts a central role in nearly all human processes, and if not appropriately accounted for, it could introduce biases when assessing skin condition. Therefore, understanding how age affects skin metabolism is crucial for creating profiles of the types and abundances of metabolites across different stages of human development. This study aimed to uncover metabolic differences in the skin among Mexican subjects of different age groups. To achieve this, surface skin samples (collected via cotton swabs) were gathered from 75 patients spanning ages 3 to 74. Metabolomic data was obtained through liquid chromatography-tandem mass spectrometry (LC-MS2), while metabolite identification and statistical analyses were performed using comprehensive yet complementary software (GNPS, Sirius, MZmine, Metaboanalyst, among others). After an exhaustive use of comprehensive chemoinformatic tools, a total of 2,529 metabolites (peptidic and non-peptidic) were putatively identified covering diverse chemical classes, such as carboxylic acids and derivatives, fatty acyls, benzene and substituted derivatives, organooxygen compounds, among others. Some metabolites are thought to be synthesized by bacteria. Through logistic regression analysis and covariate adjustment, we identified several metabolites positively and negatively associated with age, some of which were gender specific. The findings of this study include the identification of potential aging biomarkers such as cyclo(Leu-Pro), dethiobiotin, among many others, and the proposal of the major affected chemical classes, including azoles, diazines, and polypeptides. Overall, we have contributed to illuminating the chemical landscape of human skin within a Mexican population, hinting at metabolites that could potentially function as aging and disease biomarkers. Nonetheless, to validate our findings, broader studies involving diverse ethnic groups and larger sample sizes are required.

Pablo Palacio en la vanguardia

ANTONIO VLADIMIRO RIVAS ITURRALDE (2019, [Artículo])

Artículo número 9 de la Sección Tema. 14 páginas. tyvllii

Pablo Palacio (Loja, Ecuador, 1906-1947) es uno de los grandes escritores de la vanguardia en Hispanoamérica. Poco conocido hace años, las ediciones de su obra y los estudios sobre ella han ido creciendo en forma exponencial desde la década del 70. En medio del realismo social de la narrativa ecuatoriana y latinoamericana de los años veinte y treinta, Palacio se atrevió a crear una narrativa ambigua, diferente, de gran audacia formal, vanguardista. Descubrió por su propia cuenta el monólogo interior y escribió quizás la primera novela collage de la literatura hispanoamericana. Reivindicado, entre otros, por críticos como Jorge Ruffinelli, Antonio Cornejo Polar, José Miguel Oviedo y Julio Ortega, ha merecido ya la edición crítica de Archivos del Fondo en colaboración con la unesco.

Pablo Palacio (Loja, Ecuador, 1906-1947) is one of the great vanguardist writers of Latin America. Although little known a few years ago, his popularity has increased because of the growing editions of his works and the numerous studies dedicated to him. During the period of the social realism, Palacio dared a different, ambiguous, formally audacious, and vanguardist narrative. He discovered by his own the inner monologue and wrote the first collage novel in Latin American literature. Many foremost critics have vindicated his work, such as Jorge Ruffinelli, Antonio Cornejo Polar, José Miguel Oviedo and Julio Ortega, among others, and has been edited critically by Archivos del Fondo in collaboration with the UNESCO.

Rapid effects of marine reserves via larval dispersal

Richard Cudney Bueno (2009, [Artículo])

Marine reserves have been advocated worldwide as conservation and fishery management tools. It is argued that they can protect ecosystems and also benefit fisheries via density-dependent spillover of adults and enhanced larval dispersal into fishing areas. However, while evidence has shown that marine reserves can meet conservation targets, their effects on fisheries are less understood. In particular, the basic question of if and over what temporal and spatial scales reserves can benefit fished populations via larval dispersal remains unanswered. We tested predictions of a larval transport model for a marine reserve network in the Gulf of California, Mexico, via field oceanography and repeated density counts of recently settled juvenile commercial mollusks before and after reserve establishment. We show that local retention of larvae within a reserve network can take place with enhanced, but spatially-explicit, recruitment to local fisheries. Enhancement occurred rapidly (2 yrs), with up to a three-fold increase in density of juveniles found in fished areas at the downstream edge of the reserve network, but other fishing areas within the network were unaffected. These findings were consistent with our model predictions. Our findings underscore the potential benefits of protecting larval sources and show that enhancement in recruitment can be manifested rapidly. However, benefits can be markedly variable within a local seascape. Hence, effects of marine reserve networks, positive or negative, may be overlooked when only focusing on overall responses and not considering finer spatially-explicit responses within a reserve network and its adjacent fishing grounds. Our results therefore call for future research on marine reserves that addresses this variability in order to help frame appropriate scenarios for the spatial management scales of interest. © 2009 Cudney-Bueno et al.
