"Everyone collaborated and came together": The civic promise (and pitfalls) of yPAR for immigrant-origin students in an era of deportation.

OBJECTIVES: In recent years, increased anti-immigrant hostility has trickled into school settings creating toxic climates for immigrant-origin (I-O) students (Rogers, School and society in the age of trump, 2019, UCLA's Institute for Democracy, Education, and Access). Through youth participatory action research (yPAR), this study qualitatively examined how a class of Emerging Bilingual (EB) students aimed to promote more inclusive learning environments by designing, implementing, and evaluating a school-wide program. Here, we consider how the students experienced growth in their civic development as well as how they contended with resistances encountered during the project. METHODS: The current study took place at a majority I-O, northeastern high school and was led by an EB class (n = 20) and its teacher. Participants were as follows: on average 16.5 years; 60% female; and 65% Latinx, 30% Black, and 5% mixed-race (Black-Latino). Multiple data sources documenting the students' experiences were collected (including weekly student reflections and ethnographic field notes) and then thematically analyzed using open coding. RESULTS: Participating students demonstrated civic development as evidenced through: growing confidence that the program could generate positive change; enhanced sense of connection toward their classmates; and increased commitment to future civic engagement. Nonetheless, some participants demonstrated initial trepidation in both disclosing their migration stories as well as the potential efficacy of engaging in the project. Furthermore, others were disappointed by the disinterest displayed by some of their peers and teachers. CONCLUSIONS: Collaborative research can support I-O youths' civic development, though, the resistances encountered and engendered illuminate possible challenges to ensure its benefits.

Discrimination-related stress effects on the development of internalizing symptoms among Latino adolescents.

This three-wave longitudinal study of 173 Latino adolescents (M = 16.16 years, SD = 0.65) is designed to understand the role of discrimination-related stress in mental health trajectories during middle to late adolescence with attention to differences due to immigration status. The results of the growth curve analysis showed that anxious-depressed, withdrawn-depressed, and somatic complaints significantly decreased over time. Furthermore, although discrimination-related stress was found to be significantly related to the trajectories of three types of mental health symptoms, the results revealed that immigration status moderated these relations such that discrimination-related stress was significantly related to these outcomes for Latino youth whose parents were born in the United States, while this relation was not significant for Latino children of immigrants.

Actividad Citotóxica del Extracto Etanólico de Alternanthera Mexicana en las Líneas Celulares 3T3 y Hutu 80 / otoxic activity of alternanthera mexicana's ethanolic extract on 3T3 and Hutu 80 cell lines

Objetivos: Evaluar la actividad citotóxica del extracto etanólico de Alternanthera mexicana sobre las líneas celulares 3T3 y HUTU80. Materiales y métodos: Estudio experimental. Se empleó líneas celulares embrionarias de fibroblastos de ratón 3T3 y células de adenocarcinoma gástrico humano HUTU80. Para evaluar la citotoxicidad del extracto etanólico de Alternanthera mexicana se utilizó el método colorímetro SRB, y para establecer la concentración inhibitoria 50 (CI50) se realizó un análisis de regresión lineal. Se comparó el efecto del extracto etanólico de Alternanthera mexicana frente al 5-fluorouracilo (5FU). Resultados: La línea 3T3 que recibió Alternanthera mexicana creció ligeramente con un CI50 mayor de 500 mg/mL mientras que la que recibió 5-FU mostró una CI50 menor a 0,1 ug/mL. En la línea HUTU80, el CI50 del 5-FU y Alternanthera mexicana fue de 0,32 ug/ mL y 87,1 ug/mL, respectivamente. Alternanthera mexicana mostró un índice de selectividad >5,74 evidenciando mayor citotoxicidad en la línea celular tumoral (HUTU80), mientras que el 5-FU con un índice de selectividad menor que 0,31 nos indica que es más tóxico para las líneas normales. Conclusiones: Los resultados sugieren que el extracto etanólico de Alternanthera mexicana podría ser citotóxico en la línea celular HUTU80 más no en la 3T3.
