Characterization of the genetic diversity, structure, and admixture of 7 Chilean chicken breeds.

The Mapuche fowl is an autochthonous breed raised in Chile and represents an important zoogenetic resource for the local economy. This study aimed at investigating the genetic diversity, relationship and population structure of 96 local Chilean chickens derived from 3 ecotype of Mapuche fowl (Kollonka, Ketro, and Kollonka de aretes), 2 ecotype Chilean (Trintre, Cogote pelado) and 2 breeds (Light Brahma and Barred Plymouth Rock) using 12 microsatellite markers. In total, 113 alleles were detected in all populations, with a mean of 7.6 alleles per population. In all population chicken breeds, the observed and expected heterozygosity ranged from 0.91 to 0.98 and from 0.69 to 0.79. Furthermore, all populations showed significant deviations from Hardy-Weinberg expectations. Across each population, the global heterozygosity deficit (FIT) was -0.174, population differentiation index (FST) was 0.073, and the global inbreeding of individuals within breed (FIS) was -0.267. The phylogenetic relationships of chickens were examined using neighbor-joining trees constructed at the level of population. The highest Nei's standard genetic distance value of 0.559 was observed between Barred Plymouth Rock and Light Brahma, whereas the minimum value (0.099) was found between Kollonka and Trintre. The neighbor-joining tree constructed at population level revealed 2 main clusters, with Light Brahma, Barred Plymouth Rock, Ketro and Kollonka de aretes in 1 cluster, and Kollonka, Trintre and Cogote pelado breeds in the second cluster. Based on the results of the STRUCTURE analysis, the most likely number of clustering of the population evaluated was at K = 3, with Light Brahma and Barred Plymouth Rock breeds forming their own distinct clusters, while Kollonka, Ketro, Kollonka de aretes, Trintre and Cogote pelado breeds clustered together. This study represents the first report of genetic diversity in these populations in Chile. These results can be used as baseline genetic information for genetic conservation program, for instance, to control inbreeding and to implement further genetic studies in local Chilean chickens.

The neoliberal multicultural state and the urban Indigenous associative model in Santiago de Chile.

This article argues that since the recovery of democracy in Chile in the early 1990s, the state has been reshaping the Indigenous socio-political landscape by adopting neoliberal multiculturalism as a governance model. By not posing significant challenges to the state's neoliberal political and economic priorities, Indigenous cultural activity has been carefully channelled to meet state expectations of what constitutes urban indigeneity. Drawing on the minority and multicultural studies literature and ongoing ethnographic fieldwork, this article analyses how Mapuche civil society navigates the complexities of two relational models of state/ethnic minority interaction: ethno-bureaucracy and strategic essentialism. Although Mapuche associations have tried to accommodate their interests within the limits of neoliberal multiculturalism, the article argues that this governance model has established incentives for inclusion and exclusion in the socio-political apparatus, resulting in a fragmentation of the Mapuche associative landscape in urban Chile.

Gallbladder Cancer Risk and Indigenous South American Mapuche Ancestry: Instrumental Variable Analysis Using Ancestry-Informative Markers.

A strong association between the proportion of indigenous South American Mapuche ancestry and the risk of gallbladder cancer (GBC) has been reported in observational studies. Chileans show the highest incidence of GBC worldwide, and the Mapuche are the largest indigenous people in Chile. We set out to assess the confounding-free effect of the individual proportion of Mapuche ancestry on GBC risk and to investigate the mediating effects of gallstone disease and body mass index (BMI) on this association. Genetic markers of Mapuche ancestry were selected based on the informativeness for assignment measure, and then used as instrumental variables in two-sample Mendelian randomization analyses and complementary sensitivity analyses. Results suggested a putatively causal effect of Mapuche ancestry on GBC risk (inverse variance-weighted (IVW) risk increase of 0.8% per 1% increase in Mapuche ancestry proportion, 95% CI 0.4% to 1.2%, p = 6.7 × 10-5) and also on gallstone disease (3.6% IVW risk increase, 95% CI 3.1% to 4.0%), pointing to a mediating effect of gallstones on the association between Mapuche ancestry and GBC. In contrast, the proportion of Mapuche ancestry showed a negative effect on BMI (IVW estimate -0.006 kg/m2, 95% CI -0.009 to -0.003). The results presented here may have significant implications for GBC prevention and are important for future admixture mapping studies. Given that the association between the individual proportion of Mapuche ancestry and GBC risk previously noted in observational studies appears to be free of confounding, primary and secondary prevention strategies that consider genetic ancestry could be particularly efficient.

Validation of an Abbreviated Scale of the CENVI Questionnaire to Evaluate the Perception of School Violence and Coexistence Management of Chilean Students: Differences between Pandemic and Post-Pandemic.

The objective of the study was to specify an abbreviated model of the school coexistence questionnaire for non-violence (CENVI) for students from 5th to 8th grade (9 to 14 years old), in order to determine the perception of violence and management of school coexistence, and the differences between Mapuche and non-Mapuche students. A total of 1870 students from schools in the city of Temuco (Chile) responded to the CENVI questionnaire. There were two samples: (1) Pandemic, with online, face-to-face and hybrid classes; and (2) Post-pandemic, with face-to-face classes. Sample 1 consisted of 848 students aged 9 to 15 years (M = 11.90; SD = 1.27). Sample 2 consisted of 1022 students aged 9 to 14 years (M = 11.46; SD = 1.14). The questionnaire was validated using expert inter-judgment and Confirmatory Factor Analysis. A good fit of the proposed model to the data and good internal consistency measured according to the composite reliability were found, and convergent validity was demonstrated. Mapuche students perceived more physical violence and social exclusion. Cut-off points were proposed for the interpretation of the results. In the data, the effect of Coexistence Management on School Violence was null. The discussion approaches the findings from the literature on education in spaces of socio-cultural diversity in a Mapuche context.

Towards an ethical and legal framework in archeogenomics: A local case in the Atlantic coast of central Patagonia.

Ethical discussions around ancient DNA (aDNA) research predate the technological breakthroughs that led to the accelerated generation of ancient genomic data, revealing a long-due need to address these aspects in the field. Given the diverse conflicts that genomics has raised towards the communities associated with the Non-living Human Ancestors under study, it has been suggested that the ethical and legal implications of genetically studying present-day and ancient human populations should be considered case-by-case. Nevertheless, the discussions have focused on US and European perspectives. To contribute from a local and Latin American position to the problem, we present the history of consensus and disagreement of the relationships between scientists and Indigenous communities of the Atlantic coast of the central Argentinian Patagonia. We describe how these relationships resulted in the approval of a groundbreaking provincial law that acknowledges the Indigenous community's right to be involved in decision-making concerning their Ancestors. In addition, we emphasize how these established relationships allowed the development of aDNA studies. With this background, we address the main ethical concerns of genomic studies of Ancestors identified in the reference literature and commit to applying some of the recommendations suggested in those ethical guidelines. Then, we reflect on possible negative consequences of ongoing research and propose some suggestions based on personal experiences that will contribute to moving the ethical field towards a more contextualized science with a local perspective.

Chemical Fingerprinting, Aorta Endothelium Relaxation Effect, and Enzymatic Inhibition of Canelo (Drimys winteri J. R. Forst. & G. Forst, (D.C) A. Gray, Family Winteraceae) Fruits.

Drimys winteri J.R. Forst. & G. Forst (D.C) G. Gray, var. chilensis (canelo) is an endemic tree from Chile. Since pre-Columbian times, it has produced a fruit known as the canelo pepper, (pimienta de canelo) or Foye pepper, which can be used as a spice. The chemical and biological analysis of canelo fruits is reported for the first time in this study, that is, its phenolic fingerprinting by UHPLC-PDA- Q-orbitrap MS, the antioxidant activity, the enzymatic inhibitory activity, and its relaxation effects on rat aorta. The proximal composition and the mineral content (Ca: 1.45 ± 0.03 mg/100 g; Mg: 7.72 ± 0.03 mg/100 g; Fe: 4.54 ± 0.21 mg/100 g; Zn: 2.99 ± 0.02 mg/100 g; Mn: 1.08 ± 0.03 mg/100 g; Cu: 0.82 ± 0.02 mg/100 g; K: 53.03 ± 0.20 mg/100 g; Na: 0.087 ± 0.00 mg/100 g) are also reported. The canelo fruits showed a total phenolic content of 57.33 ± 0.82 mg GAE/g dry weight. In addition, the total flavonoid content was 38.42 ± 1.32 mg equivalent of QE/g dry weight. The antioxidant activity was evaluated by employing DPPH and ABTS methods (IC50 of 6.65 ± 0.5 and 9.5 ± 0.05 µg/mL, respectively), ORAC (25.33 ± 1.2 µmol Trolox/g dry plant) and FRAP (45.56 ± 1.32 µmol Trolox/g dry plant). The enzymatic inhibition of acetylcholinesterase, butyrylcholinesterase, and tyrosinase (IC50: 1.94 ± 0.07, 2.73 ± 0.05, and 9.92 ± 0.05 µg extract/mL, respectively) is also reported. Canelo extract led to an 89% relaxation of rat aorta. Our results confirm that D. winteri fruits are a rich source of secondary metabolites and can inhibit enzymes associated with neurodegenerative diseases; the results also suggest that canelo may induce a potentially hypotensive effect in rat aorta. The study demonstrates the medicinal properties of canelo fruit and spice.

El pueblo indígena mapuche en argentina, 1992-2022: treinta años de revitalización de la identidad, movilizaciones e interpelación al estado

El pueblo mapuche es uno de los grupos originarios de mayor importancia y nivel de conocimiento público en los países del Cono Sur de América del Sur, tanto en Chile como en Argentina, con crecientes conflictos con propietarios privados y algunos niveles estatales. Nos proponemos abordar las movilizaciones y repercusiones públicas de este pueblo a partir del accionar de sus movimientos y comunidades asentados en la zona del Parque Nacional Nahuel Huapi y áreas aledañas, en la región cordillerana de las provincias de Neuquén y Río Negro, en la Patagonia argentina. Daremos cuenta del recorrido en este periodo de 1992 hasta el presente, en el cual el pueblo mapuche se va transformando en un sujeto social y político. Analizaremos estos aspectos a la luz de las diversas transformaciones socioeconómicas y los efectos de la aplicación de las diferentes políticas públicas y legislaciones.

The Mapuche people are one of the most important and publicly known indigenous groups in the Southern Cone countries of South America, both in Chile and Argentina, and they have increasingly taken part in conflicts with private landowners and some levels of government. This article addresses the mobilizations and public repercussions of the actions of the Mapuche people, looking into their movements and communities set in the Nahuel Huapi National Park and surrounding areas, in the mountainous region of the provinces of Neuquén and Río Negro, in Argentine Patagonia. We will account for the period between 1992 and the present, during which the Mapuche people become a social and political subject. We will analyze these aspects in the light of the various socioeconomic transformations and the effects of the application of different public policies and legislations.

After-school sports programmes and social inclusion processes in culturally diverse contexts: Results of an international multicase study.

This research aimed to understand the role of after-school sports programs in social inclusion processes in culturally diverse contexts through a multicase study within two locations. The first location was in Spain where immigrant and Spanish students were enrolled, and the other was in Chile with Mapuche-Huilliche students, immigrant and Chilean students. The implemented programs at both sites were similar in their educational focus on socio-educational values, and teaching models (hybridization of teaching games for understanding and cooperative learning) that enhance social inclusion. Using individual and group interviews with teachers, sports coordinators, parents, and students, a qualitative approach was used to identify the factors that facilitate or hinder the social inclusion processes. In addition, the researchers used qualitative observations of the programs over six months using "notes logbook" to record their impressions during the observation process. Results indicated that the implemented sports programs successfully facilitated social inclusion processes, enabling the development of interpersonal skills and relationships between students from different cultural backgrounds. The previous training and experiences of teachers in culturally diverse contexts, and incorporation of traditional sporting games from all cultures, seems to be an important facilitator factor for the inclusion potential of the implemented programs.

Prevalence of Cryptosporidium spp. in Horses from communities of the Mapuche native people, Araucanía Region, Chile.

BACKGROUND: There are no studies of potential zoonotic diseases in Mapuche communities' horses. OBJECTIVES: The objective of this study was to determine the prevalence of Cryptosporidium in horses of the Mapuche communities. STUDY DESIGN: This was a cross-sectional study. METHODS: Faecal samples from 100 randomly selected horses (n = 100) were taken from rural Mapuche communities from four municipalities from the Araucanía Region. These samples were processed with the modified Ziehl-Neelsen staining technique and grouped by sex, age and municipality. RESULTS: The general prevalence of Cryptosporidium spp. was 67.0% (n = 67). The prevalence was 51.0% (n = 51) in males and 49.0% (n = 49) in females, and there is no gender association to the presentation of Cryptosporidium spp. The prevalence by municipality was 60.0%, 80.0%, 64.0% and 64.0% in Curarrehue, Lonquimay, Padre las Casas and Teodoro Schmidt, respectively. The above shows no significant association between the sector and the presence of Cryptosporidium spp. The prevalence by age was 95.4% of horses tested positive for Cryptosporidium between birth and 6 years of age. About 27.3% of horses were tested positive in the age group between 7 and 10 years. There was no presence of Cryptosporidium spp. in the age group older than 11 years, showing a significant relationship between the age of the animal and the presence of Cryptosporidium (P Ë‚ 0.05). MAIN LIMITATIONS: The sample analysis did not specifically identify the type of Cryptosporidium, and it was not possible to evaluate the zoonotic risk in the Mapuche communities. CONCLUSIONS: Cryptosporidium spp. is present in working horses in Mapuche communities, with a 67.7% general prevalence, and there is a significant association between this parasite and the age of the horses, being higher in the age group between 0 and 6 years, with a prevalence of 95.4%. There may be a potential zoonotic risk in the Mapuche communities.

HISTORIAL: No hay estudios sobre enfermedades potencialmente zoonoticas en caballos de las comunidades Mapuche. OBJETIVOS: El objetivo de este estudio es determinar la prevalencia de Cryptosporidium en caballos de las comunidades Mapuche. DISEÑO DEL ESTUDIO: Estudio transversal. MÉTODOS: Muestras fecales de cien caballos (n = 100) seleccionados al azar, fueron recolectadas en comunidades Mapuche de cuatro municipalidades de la Región de la Araucanía. Estas muestras fueron procesadas con la técnica de tinción Ziehl-Neelzen modificada y agrupadas por sexo, edad y municipalidad. RESULTADOS: La prevalencia general de Cryptosporidium spp fue de 67.0% (n = 67). La prevalencia fue 51.0% (n = 51) en machos y 49.0% (n = 49) en hembras, y no hay asociación de genero con la presentación de Cryptosporidium spp. La prevalencia por municipalidad fue de 60.0%, 80.0%, 64.0%, 64.0% en Curarrehue, Lonquimay, Padre las Casas y Teodoro Schmidt respectivamente. Lo presentado arriba muestra ninguna asociación significativa entre el sector y la presencia de Cryptosporidium spp. La prevalencia por edad fue de 95.4% en caballos que resultaron ser positivos a Cryptosporidium entre nacimiento y seis años de edad. 27.3% resultaron ser positivos entre siete y diez años. No hubo presencia de Cryptosporidium spp en el grupo mas grande de caballos mayores a once años, mostrando una relación significativa entre la edad del animal y la presencia de Cryptosporidium (P < 0.05). LIMITACIONES PRINCIPALES: El análisis de muestras no fue especifico para poder identificar el tipo de Cryptosporidium, y no fue posible evaluar el riesgo zoonotico en la comunidades Mapuche. CONCLUSIONES: Los resultados de este estudio concluyeron que existe la presencia de Cryptosporidium spp en caballos de trabajo en las comunidades Mapuche; con un 67.0% de prevalencia, y que hay una asociación significativa entre este parasito y la edad de los caballos, siendo mayor en el grupo etario entre 0 y 6 años, con una prevalencia de 95.4%. Estos resultados pueden inferir que podría haber un riesgo zoonotico potencial en las comunidades Mapuche.

Escuchando a los abuelos: transdisciplina, aves y gente para cultivar la memoria biocultural / Listening to elders: transdisciplinarity, birds and people to cultivate biocultural memory / Ouvindo os avós: transdisciplina, pássaros e pessoas para cultivar a memória biocultural

Resumen (analítico) Presentamos una iniciativa y proponemos una metodología transdisciplinaria para cultivar la memoria biocultural, basada en los procesos de participación y materialización en comunidades de práctica (educativas). Presentamos el proyecto «Escuchando a los abuelos¼, que buscó facilitar diálogos intergeneracionales en tres escuelas mapuche (~ 90 niños y niñas) en Wallmapu, Chile. «Escuchando a los abuelos¼ utilizó a las aves como protagonistas de narrativas locales sobre el territorio. Cocreamos un ciclo de cinco pasos para promover la participación y la materialización. Los niños y niñas desarrollaron un ejercicio de abstracción para dar significado a las narrativas que ellos mismos recopilaron para crear memes positivos sobre las aves. Estos memes fueron comunicados dentro y más allá de sus comunidades. Concluimos que la experiencia de los abuelos debe ser honrada para contrarrestar la actual extinción de la experiencia biocultural.

Abstract (analytical) This article presents an initiative and proposes a transdisciplinary methodology to cultivate biocultural memory based on the processes of participation and materialization in (educational) communities-of-practice. We implemented the project "Listening to elders" that sought to facilitate intergenerational dialogues in three mapuche schools (with approximately 90 children) in Wallmapu, Chile. Listening to elders used birds as the basis of constructing local narratives about the territory. We co-created a 5-Step cycle to promote participation and materialization. The children participated in an abstraction exercise to give meaning to the narratives they constructed themselves to create positive memes involving birds. These memes were communicated within and beyond their communities. The authors conclude that the experiences of elders must be honored in communities to counter the current dynamic involving the extinction of biocultural experience.

Violencia estatal y movimientos sociales mapuche: pichikeche violentados, una rebelión incubada / State violence and Mapuche social movements: violence committed against pichikeche in an incubated rebellion / Violência estatal e movimentos sociais Mapuche: atacou pichikeche, uma rebelião incubada

Resumen (analítico) El Estado chileno ha ejercido violencia contra el pueblo mapuche por generaciones, promoviendo la construcción de imaginarios en pichikeche (niños y niñas), lo que impacta en la expresión política de los movimientos sociales. Para analizar dicho impacto se usó una metodología cualitativa con diseño etnográfico. Los datos se obtuvieron mediante observación participante, entrevistas y dibujos. Participaron pichikeche de 5 a 12 años de edad, pertenecientes a cinco familias mapuche, respaldados por loncos (dirigentes) de su comunidad. Los resultados muestran que los imaginarios de dolor e incomprensión frente a la violencia, racismo y crueldad por parte del Estado pueden promover la generación de movimientos sociales que incluyen respuestas similares en colectivos de personas que carecieron de estrategias para la contención y resignificación de tales eventos traumáticos. A esto se le denomina «rebelión incubada¼.

Abstract (analytical) The Chilean State has committed violence against the Mapuche people for generations, promoting Mapuche children's construction of imaginary realities. This situation has an impact on the political expression of social movements. A qualitative methodology based on an ethnographic design was used. Data generation techniques included participant observation, interviews and pichikeche's drawings. The participants in this study were pichikeche (children) between 5 and 12 years of age from five Mapuche families supported by loncos (leaders) from their community. The results suggest that imaginary pain and misunderstanding caused by excessive and unjustified violence, racism and cruelty carried out by the State against Mapuche communities has promoted the generation of social movements. This could provoke a similar response among people who lack strategies for the containment and defining of these traumatic events, which is known as an incubated rebellion.

Perception of School Violence: Indicators of Normalization in Mapuche and Non-Mapuche Students.

The current social and political scenario in Chile has opened up the debate on two centuries of usurpation and discrimination towards the Mapuche people. Educational centers are not oblivious to the social exclusion faced by indigenous children and young people, and this forms part of the phenomenon of school violence. This study explores the differences in perception between Mapuche and non-Mapuche students regarding school violence. The issue is the lack of knowledge regarding cultural variations in the perception of school violence in spaces of social and cultural diversity in the Mapuche context. This study describes the characteristics of school violence perceived by students in relation to differences based on ancestry and characterizes the variations in perception. A total of 1404 students participated from urban schools in the city of Temuco, Chile, aged 10 to 13 (M = 11.4; SD = 1.1) who completed the CENVI questionnaire. The confirmatory factor analysis (CFA) of the total sample and categories provides indexes that fit the proposed model. The omega coefficients provide internal reliability guarantees. This study tests configural, metric and scalar invariance for all the categories explored, and statistically significant differences are found between Mapuche and non-Mapuche students in the perception of physical and verbal violence, where the Mapuche student perceives more violence. Results are discussed based on existing research on education in spaces of social and cultural diversity in the Mapuche context, with research into elements that can help explain the findings.

Cultural labor and the defetishization of environments: connecting ethnographies of tourism in Venezuela and Chile.

This paper compares the development of the tourism industry in two different Latin American locations: a municipality of Chile's Araucanía and Venezuela's Gran Sabana. In both locations, part of the indigenous population shows interest in the development of this industry, which presents potential as a source of locally generated income. This comparison focuses on examining how property rights and relations shape and are reshaped by the expansion of tourist activities in these locations, shedding light on two additional questions: first, the socioeconomic conditions that help explain the increasing participation of the indigenous population in the expansion of tourism in these regions; second, a cultural phenomenon that this expansion stimulates: the circulation of discursive representations of local environments as permanently inscribed with a particular form of collective labor. This paper will conceptualize this labor as "cultural labor" and, drawing from theorizations of the fetishism of commodities, will argue that the widespread appeals to this labor constitute a (paradoxical) form of discursive defetishization that is fostered by the logic of the tourist industry. This form of defetishization discursively subverts the principle of concealment that pervades commodity fetishism as theorized by Marx, but it is nonetheless a functional part of a social process that reinscribes and rearticulates capital as a social relation among the populations of these regions.

Experiencias de salud mapuche en Atención Primaria de Salud desde trabajadores sanitarios y usuarios/as en zona urbana de Chile / Mapuche health experiences in Primary Health Care from health workers and users in urban Chile

Resumen Este estudio describe experiencias y percepciones sobre interculturalidad en Atención Primaria de Salud (APS) desde la perspectiva de trabajadores/as y usuarios/as de salud mapuche. Se realizó una sistematización cualitativa de experiencias de un Programa de Salud Intercultural en APS en una comuna urbana de Chile. Participaron 19 usuarios/as y 13 trabajadores/as en entrevistas individuales y tres entrevistas grupales, respectivamente. Se realizó un análisis de contenido semántico. Para los participantes, la salud mapuche es percibida positivamente, los/as usuarios/as la asimilan al concepto de interculturalidad, mientras que los/as trabajadores/as señalan que, si bien se respeta, no se promueve un trabajo integrado. Los/las participantes identifican como barreras aspectos administrativos, falta de integración y cuestionamientos científicos. Se requiere reconocimiento de la salud indígena y mayor formación de trabajadores/as sobre salud indígena e interculturalidad.

Abstract This study describes experiences and perceptions on interculturality in Primary Health Care (PHC) from the perspective of health workers and Mapuche health users. For this purpose, a qualitative systematization of these experiences was carried out in a PHC Intercultural Health Program at an urban commune in Chile. Data were collected by means of individual and group interviews, respectively, with 19 users and 13 professionals. The semantic content analysis was performed. While service users perceive Mapuche health positively, assimilating it to the concept of interculturality, health workers reported that Mapuche health is respected but no integrated work is promoted. As barriers, participants cited administrative aspects, lack of integration, and scientific issues. In conclusion, recognition of indigenous health and greater occupational training on indigenous health and interculturality is necessary.

El concepto cultural de bienestar en niñas y niños Mapuche: Perspectivas de sus cuidadores y autoridades ancestrales / The well-being concept of Mapuche children: Cultural perspectives of their caregivers and ancestral authorities

El concepto de salud y bienestar es cultural, social e históricamente dependiente, y al mismo tiempo obedece a diversos enfoques socio-políticos. Lo que se considera sano, enfermo, o en buenas condiciones generales de salud depende de los valores y expectativas que se tiene de las personas y sus cuerpos en las diversas culturas. En nuestro país la infancia mapuche se encuentra en una interfaz entre valores de la modernidad y aquellos propias del mundo mapuche; así sus cuidadores velan por la protección y traspaso de valores culturales esenciales. Este estudio, se propone indagar en los conceptos de salud, bienestar y enfermedad asociados al desarrollo y crianza de niños y niñas mapuche desde la perspectiva de sus cuidadores, familiares y autoridades ancestrales. Es un diseño cualitativo basado en Teoría Fundamentada; los datos se recolectaron mediante entrevistas en profundidad y observaciones dirigidas hacia el cuidado infantil en el propio ambiente familiar. El análisis se realizó en el programa Atlas ti.8, mediante segmentación, codificación y elaboración de categorías. Los resultados indican que salud y bienestar se traduce en el concepto küme mongen, küme felen (estar bien, en armonía con todo). Así, estar sano es crecer conforme al entorno, como una planta que se alimenta naturalmente, los niños/as tienen ganas de nutrirse, no tienen enfermedades y sus cuerpos son firmes y fuertes. Niños y niñas deben demostrar la adquisición de destrezas especialmente autonomía, caerse y levantarse sin llorar, no ser temerosos, ser activos, atentos a mirar y escuchar lo que ocurre a su alrededor e interesados en aprender.

The concept of health and well-being is culturally, socially and historically dependent, and at the same time is dependent of various socio-political approaches. What is considered healthy or sick, depends on the values and expectations that people have in different cultures. In our country, Mapuche childhood is at in the interface between the values of modernity and those of the Mapuche world. Thus, their caregivers ensure the protection and transfer of essential cultural values. This study aims to investigate the concepts of children health and well-being, from their caregivers, relatives, and ancestral authorities' perspectives. It is a qualitative design based on Grounded Theory; the data were collected through in-depth interviews and observations. The analysis was carried out in the Atlas ti.8 program, through segmentation, coding and categories construction. The results indicate that health and well-being correspond to the mapuche concept of küme mongen, küme felen (means to be well, being in harmony with everything). Thus, to be healthy is to grow according to the environment and spiritual context, like a plant that feeds naturally children want to nourish themselves, their bodies must be firm and strong. Boys and girls must demonstrate the acquisition of certain skills especially autonomy, for example, to be strong, active and attentive to look and listen to what is happening around them and interested in learning.

Phenolic composition, antioxidant capacity and α-glucosidase inhibitory activity of raw and boiled Chilean Araucaria araucana kernels.

The Araucaria araucana kernels are a traditional food in southern Chile and Argentina. The aim of this work was to determine the composition of the phenolic-enriched extracts (PEEs) of the boiled kernels as well as their antioxidant capacity, inhibitory activity on metabolic syndrome-associated enzymes and effect on postprandial oxidative stress in a simulated gastric digestion model. The PEEs composition was assessed by HPLC-DAD-MS/MS. The main PEEs constituents were catechin and epicatechin in the unbound form, while hydroxybenzoic acids occurred mainly in the bound form. The unbound phenolics from boiled kernels showed significant correlations with DPPH, FRAP, TEAC (Pearson's r of 0.481, 0.331 and 0.417, respectively) and lipid peroxidation (r = 0.381) and were more active than the bound phenolics. The extracts were highly active against α-glucosidase (IC50: 0.33-3.15 µg/mL) and reduced lipoperoxidation. Traditional processing increases the flavan-3-ol content. Our results suggest that this traditional food has potential health promoting properties.

Diferencias del somatotipo entre niños mapuche y no mapuche de 12 - 13 años de Malleco ­ Araucanía ­ Chile / Somatotype Differences Between Mapuche And Non-Mapuche Children Of 12 - 13 Years Old From Malleco - Araucania - Chile

Los estudios somatotípicos y su descripción de la configuración morfológica humana permitir apreciar impactos en hábitos alimentarios y sedentarismo. Este estudio determinó la diferencia somatotípica niños mapuche (NM) y no mapuche (NNM) de Malleco, Chile. Se evaluaron a través del protocolo ISAK, 160 niños con edad media de 12,5 años, talla 145,5 ± 3,5 cm y peso 43,7 ± 3 kg., Obteniendo las siguientes clasificaciones: Grupo 12 años, Mapuche; Meso-endomorfos. Grupo no mapuche 12 años; Endo-mesomorfo. Grupo 13 años, mapuche; Meso-endomorfos. Grupo no mapuche 13 años; Endo-mesomorfo. Los resultados indican que para la edad de 12 años, los NM presentan valores más bajos de endomorfía y valores más altos de mesomorfía (p≤0.01) que NNM. Los NM de 13 años presentaron valores más bajos de endomorfía y mesomorfía (p≤0.01) que NNM. En conclusión,

Somatotypic studies and their description of the human morphological configuration allow to appreciate impacts on eating habits and sedentary lifestyle. This study determined the somatotypic difference in Mapuche (NM) and non-Mapuche (NNM) children from Malleco, Chile. Through the ISAK protocol, 160 children with a mean age of 12.5 years, height 145.5 ± 3.5 cm and weight 43.7 ± 3 kg were evaluated, obtaining the following classifications: Group 12 years, Mapuche; mesoendomorphs. Non-Mapuche group 12 years; Endomesomorph. Group 13 years old, Mapuche; Mesoendomorphs. Non Mapuche group 13 years old; endomesomorph. The results indicate that for the age of 12 years, the NM presented lower values of endomorphy and higher values of mesomorphy (p≤0.01) than NNM. The 13-year-old NMs presented lower endomorphy and mesomorphy values (p≤0.01) than NNM. In conclusion, Mapuche schoolchildren present a mesomorphic predominance, however, NNM present a predominance of the endomorphic component.

Racismo y prejuicios encubiertos: Las luchas antirracistas de mujeres mapuche en Chile / Covert Racism and Prejudice: The Anti-Racist Struggles of Mapuche Women in Chile

La expresión de los prejuicios, en los últimos años, es más encubierta que manifiesta. Dicha expresión encubierta busca mantener las exclusiones sociales por razones de raza, clase y gé-nero. Algunas de las razones que las justifican responden a los contextos democráticos y a las sucesivas demandas por los derechos de los pueblos originarios en América Latina. En este con-texto, el objetivo que nos propusimos en este artículo fue analizar comprensivamente las expe-riencias de prejuicios manifiestos y sutiles de mujeres mapuche en Chile, a través de las cuales dichas mujeres crean luchas antiracistas, anticlasistas y antipatriarcales. Por medio de una et-nografía multisituada, con entrevistas en profundidad, damos cuenta de las experiencias de 20 mujeres de las regiones Metropolitana, Biobío, La Araucanía y Los Ríos. Los resultados nos muestran que el racismo manifiesto, y los prejuicios encubiertos, coexisten y varían de acuerdo a las condiciones sociales de las mujeres. (AU)

The expression of prejudice in recent years is more covert than overt. Such covert expression seeks to maintain social exclusions on the basis of race, class and gender. Some of the reasons that justify them respond to democratic contexts and the successive demands for the rights of native peoples in Latin America. In this context, the objective of this article is to comprehen-sively analyse the experiences of overt and subtle prejudices of mapuche women in Chile, through which these women create anti-racist, anti-classist and anti-patriarchal struggles. Through a multi-site ethnography, with in-depth interviews, we report on the experiences of 20 women from the Metropolitan, Biobío, La Araucanía and Los Ríos regions. The results show that overt racism and hidden prejudices coexist and vary according to women’s social conditions. (AU)

New and old knowledge aimed at decolonising mental health: reflections and proposals from Chile.

Assuming that coloniality and its expression in hegemonic medicine and conventional psychiatry are present in most Latin American countries, this article explores unknown dimensions of decolonisation: the subjective, but social process of decolonisation of the being in hegemonic groups as the physicians. Although in Chile there are new models and state programmes that promote collective mental health and interculturality, they generally fail because they are trapped in the colonial system of power/knowledge and life/being. Grounded on the perspective of critical interculturality, we need to rethink mental health from the colonial difference to propose a new epistemology of power/knowledge and life/being based on indigenous concepts as well-being. Considering structural transformation as a key issue, through a case study of a lived intercultural experience, we point out that the activation of the decolonisation process requires not only new models of mental health but also a profound epistemic subjective transformation of physicians as colonised subjects.

Genetics of Mexico Jamiltepec Oaxaca Mixtec Amerindians according to HLA genes.

Mexican Mixtec population from coastal Jamiltepec (Oaxaca) Amerindians was studied for its HLA profile. They show genetic characteristics close to Pacific Islanders and other Mexican Isthmus Amerindians (Mazatecans, Zapotecans and Mayas). Interestingly, this coastal Oaxaca Mixtec population is genetically closer to Mazatecans than to Oaxaca Mixtec from mountains according to HLA genes. Mixtec HLA frequent extended haplotype A*24:02-B*35:14-DRB1*16:02 has been also found in Jaidukama North Colombia forest Amerindians and in Guatemala Mayas; A*24:02, DRB1*04:03, DRB1*04:04 and DRB2*16:02 are frequent alleles also common to Pacific Inhabitants. Notwithstanding, Mixtecs show deep cultural and genetic roots with Mesoamerican Amerindians and all of them probably contributed to construct Monte Alban culture around an important Pyramid Complex close to Oaxaca City.
