ABSTRACT We characterized the surf-zone fish assemblage structure of an ocean beach on the central coast of Brazil (Guriri Beach, Espírito Santo) and assessed its diel variability. Like the entire Espírito Santo coast, Guriri Beach was also affected by ore tailings from the Fundão dam, which collapsed on November 5, 2015. Monthly samplings were carried out before the dam collapse along a year cycle (May 2013-April 2014), during the day and night in the neap tide, using a beach seine. A total of 2217 specimens were caught (1017 during the day and 1200 at night), distributed in 36 fish species and 20 families. Juveniles of the kingcroaker Menticirrhus spp., great pompano Trachinotus goodei, Florida pompano Trachinotus carolinus, littlescale threadfin Polydactylus oligodon, and Atlantic sabretooth anchovy Lycengraulis grossidens dominated the fish fauna, accounting for 84% of the total capture. The fish assemblage structure changed irregularly between day and night throughout the year. P. oligodon and Menticirrhus spp. were more abundant at night, whereas T. carolinus and L. grossidens were more abundant during the day. In most cases, no significant change was detected in fish abundance and richness between the day and night; when significant differences were detected, abundance and richness were higher at night. Our findings could support a monitoring program of the local surf-zone fish fauna and serve as before-impact data, allowing more accurate quantification of the ore tailings' impacts on the local fish biodiversity.

SUMMARY: The study on cadavers, although considered fundamental in the teaching of human anatomy, is limited in several universities, mainly due to the acquisition and manipulation of cadaveric material. Throughout history, several artificial anatomical models have been used to complement the real anatomical pieces. The present study offers a new alternative: the making of three-dimensional models from Computed Tomography (3D-CT) patient image acquisition. CT images from the USP University Hospital database were used. Patients underwent examinations for reasons other than the present study and were anonymized to maintain confidentiality. The CT slices obtained in thin cross-sections (approximately 1.0 mm thick) were converted into three-dimensional images by a technique named Volume Rendering for visualization of soft tissue and bone. The reconstructions were then converted to an STL (Standard Triangle Language) model and printed through two printers (LONGER LK4 Pro® and Sethi S3®), using PLA and ABS filaments. The 3D impressions of the thigh and leg muscles obtained better visual quality, being able to readily identify the local musculature. The images of the face, heart, and head bones, although easily identifiable, although seemed to present lower quality aesthetic results. This pilot study may be one of the first to perform 3D impressions of images from CT to visualize the musculature in Brazil and may become an additional tool for teaching.

RESUMEN: El estudio en cadáveres, a pesar de considerarse un aspecto fundamental en la enseñanza de la anatomía humana, se encuentra limitado en varias universidades, principalmente por la adquisición y manipulación de material cadavérico. A lo largo de la historia se han utilizado varios modelos anatómicos artificiales para complementar las piezas anatómicas reales. El presente estudio ofrece una nueva alternativa: la elaboración de modelos tridimensionales a partir de la adquisición de imágenes de pacientes por Tomografía Computarizada (3D-CT). Se utilizaron imágenes de TC de la base de datos del Hospital Universitario de la USP. Los pacientes se sometieron a exámenes por razones distintas al presente estudio y fueron anonimizados para mantener la confidencialidad. Los cortes de TC obtenidos en secciones transversales delgadas (aproximadamente 1,0 mm de grosor) se convirtieron en imágenes tridimensionales mediante una técnica denominada Volume Rendering para la visualización de tejido blando y hueso. Luego, las reconstrucciones se convirtieron a un modelo STL (Standard Triangle Language) y se imprimieron a través de dos impresoras (LONGER LK4 Pro® y Sethi S3®), utilizando filamentos PLA y ABS. Se obtuvo una mejor calidad visual de las impresiones 3D de los músculos del muslo y la pierna, pudiendo identificar fácilmente la musculatura local. Las imágenes de la cara, el corazón y los huesos de la cabeza, aunque fácilmente identificables, parecían presentar resultados estéticos de menor calidad. Este estudio piloto puede ser uno de los primeros en realizar impresiones 3D de imágenes de TC para visualizar la musculatura y podría ser en una herramienta adicional para la enseñanza.

ABSTRACT Podzols are highly sandy soils, in which elements, such as potassium, needed by crops, are easily leached. Studies have indicated that biochar can contribute to increasing cation exchange capacity of the soil, which can improve the retention of bases. This study aimed to evaluate the effect of the poultry litter biochar combined or not with increasing doses of KCl, on leaching and soil base content, on the production of green manure biomass, and on the distribution of K in the soil-water-plant system. A 2 × 3 factorial experiment was conducted in randomized blocks with 6 repetitions: without and with biochar (1% v / v, produced from poultry litter) × without K, with 53.65 and 107.30 mg dm-3 of K (as KCl). The experiment was carried out in four steps: Step 1) Soil incubation with the treatments (for 20 days) followed by chemical analysis of the soil; Step 2) First leaching: the containers (made with PVC with 0.30 m high) received the newly incubated soil in the surface layer and soil without treatment in the subsurface layer. The containers received water until saturation plus 50 % of the total pore volume and the leached water was collected and analyzed; Step 3) Cultivation of green manure (Mucuna aterrima) in the containers of Step 2 and harvest within 40 days (evaluation of biomass and K content); Step 4) after the mucuna harvest, the containers were subjected to second leaching. The leaching solution and the soil from the surface and subsurface layers were collected for chemical analysis. Biochar increased the pH, cationic exchange capacity, P, K, Ca, and Mg levels in the newly incubated soil, in the surface and subsurface layer. The increasing doses of KCl proportionally increased biomass production and K accumulation in green manure, and the biochar increased this response and reduces the need for potassium fertilization by 50 %. With biochar, the accumulation of total K in the soil-plant-water system increases by 125 % and, in the soil-plant system, by 145 %. Biochar changes the K ratio in the soil-plant-water system. With biochar, proportionally, the highest accumulated percentage of K occurred mainly in the soil surface and subsurface layer, and did not result in higher percentages of K in the leached water. Biochar produced from poultry litter can be used as a good alternative to improve the chemical properties of Podzols and reduce nutrient losses.

Abstract Introduction The treatment of cholesteatoma is generally surgical, and the major obstacle is the high prevalence of recidivism. The endoscopic ear surgery technique is proposed to minimize this problem. Objectives To utilize endoscopes to visualize and manipulate cholesteatoma residues after microscopic removal Methods Cross-sectional study. Thirty-two patients with cholesteatoma underwent microscopic wall-up mastoidectomy combined with the endoscopic approach. The subjects were assessed for the presence and location of covert disease. Results Of the 32 cases, 17 (53.12%) had residual cholesteatoma in the endoscopic phase. Minimal disease was found, usually fragments of the cholesteatoma matrix. Pars tensa cholesteatomas had more covert disease than pars flaccida cholesteatomas (62.50% vs 43.75%). Posterior recesses (47.05%) and tegmen tympani (41.17%) were the locations with more covert disease (p< 0.05). Conclusion Cholesteatomas of the pars tensa presented more residual disease and were significantly more common in the posterior recesses and tegmen tympani.

Resumen Introducción: la fibrosis pulmonar idiopática (FPI) es una enfermedad pulmonar intersticial (EPID) de mal pronóstico, considerada huérfana en Colombia. Un diagnóstico correcto tiene implicaciones para el paciente y los costos de atención. Los grupos de discusión multidisciplinaria (GDM) se consideran el estándar de oro en el diagnóstico. No hay estudios previos en Colombia de la experiencia de un GDM. Objetivos: evaluar el impacto de un GDM en una institución de cuarto nivel en Bogotá en cambio de diagnóstico de pacientes con EPID y la concordancia entre el diagnóstico inicial y final de FPI. Material y métodos: pacientes con EPID evaluados entre 2015-2018 por el GDM conformado por neumólogos, radiólogo, patólogo y reumatólogos. Criterios ATS/ERS/JRS/ALAT de diagnóstico de FPI. Descripción del cambio en el diagnóstico y concordancia entre el diagnóstico inicial y del GDM en FPI. Resultados: de 165 pacientes con EPID se cambió el diagnóstico en 35.2%. En 77.3% pacientes con diagnóstico inicial de FPI y en 6.7% con diagnóstico inicial diferente a FPI el GDM confirmó FPI. Al descartar FPI, los principales diagnósticos fueron neumonitis de hipersensibilidad en fase crónica (29.4%) y neumonía intersticial no específica (23.5%). El índice kappa entre el diagnóstico inicial y final de FPI fue 0.71 (0.60-0.82). Conclusiones: el GDM en EPID tuvo un importante impacto clínico demostrado por un alto porcentaje de cambió del diagnóstico de remisión. Se descartó el diagnóstico inicial de FPI en un porcentaje significativo de pacientes y se ratificó en un grupo menor sin esta sospecha clínica inicial. (Acta Med Colomb 2022; 47.

Abstract Introduction: idiopathic pulmonary fibrosis (IPF) is an interstitial lung disease (ILD) with a poor prognosis, considered an orphan disease in Colombia. An accurate diagnosis has implications for the patient and healthcare costs. Multidisciplinary discussion groups (MDGs) are considered the gold standard for diagnosis. There are no prior studies in Colombia on the experience of an MDG. Objectives: to evaluate the impact of an MDG in a quaternary care institution in Bogotá on the change in the diagnosis of patients with ILD and the concordance between the initial and final diagnosis of IPF. Materials and methods: patents with ILD evaluated from 2015-2018 by the MDG made up of pulmonologists, a radiologist, a pathologist and rheumatologists. The ATS/ERS/JRS/ALAT diagnostic criteria for IPF. A description of changes in the diagnosis and the agreement between the initial diagnosis and the MDG diagnosis of IPF. Results: out of 165 patients with ILD, the diagnosis was changed in 32.5%. The MDG confirmed IPF in 77.3% of patients with an initial diagnosis of ILD and 6.7% of those with a different initial diagnosis. When IPF was ruled out, the main diagnoses were chronic hypersensitivity pneumonitis (24.8%) and nonspecific interstitial pneumonia (23.5%). The Kappa index between the initial and final IPF diagnoses was 0.71 (0.60-0.82). Conclusions: the MDG on ILD had a significant clinical impact evidenced by a high percentage of change in the referral diagnosis. The initial diagnosis of IPF was ruled out in a significant percentage of patients and confirmed in a smaller group which did not have this initial clinical suspicion. (Acta Med Colomb 2022; 47.

BACKGROUND: There exist many psychosocial sequelae associated with mobility impairment, especially in low-resource settings where access to mobility assistive devices is limited OBJECTIVES: This study aims to (1) define the burden and presenting aetiologies of mobility impairment in the rural Northern Region of Malawi and (2) assess the relationship between physical disability, life satisfaction and access to mobility aids METHODS: At mobility device donation clinics throughout the Northern Region of Malawi, adults living with mobility impairment were surveyed with a demographic questionnaire and a series of validated surveys to assess their physical activity levels (Global Physical Activity Questionnaire [GPAQ]), degree of mobility impairment (Washington Group Extended Set Questions on Disability) and life satisfaction (patient-reported outcomes measurement information systems satisfaction with participation in social roles and general life satisfaction RESULTS: There were 251 participants who qualified for inclusion, of which 193 completed all surveys. Higher physical activity scores were positively correlated with increased life satisfaction: (1) satisfaction with participation in social roles (0.481, p < 0.0001) and (2) general life satisfaction (0.230, p < 0.001). Respondents who had previously used a formal mobility device reported 235.5% higher physical activity levels ([139.0%, 333.0%], p = 0.006), significantly higher satisfaction with participation in social roles ([0.21, 6.67], p = 0.037) and equivocally higher general life satisfaction ([−1.77, 3.84], p = 0.470 CONCLUSION: Disability and mental health do not exist in isolation from one another. Given the positive correlations between formal mobility device usage and both physical activity and life satisfaction, interventions that increase access to mobility-assistive devices in undertreated populations are imperative CONTRIBUTION: This study contributes to the understanding of the complex relationship between physical disability, access to mobility aids, and life satisfaction. Results from this study suggest the potential benefit that increasing access to mobility aids may have in improving the quality of life of mobility impaired persons in resource-limited settings, such as the Northern Region of Malawi

Resumo As ilhas costeiras do Grande Rio, ao sul das cidades do Rio de Janeiro e Maricá, têm sofrido múltiplos impactos antrópicos. Apesar destes problemas, esses sistemas insulares abrigam uma grande diversidade de espécies de peixes. Os peixes recifais são componentes essenciais das comunidades costeiras marinhas tropicais, fornecendo alimento e fonte de renda para milhões de pessoas em todo o mundo. Neste trabalho, geramos uma lista de verificação atualizada do Monumento Natural das Ilhas Cagarras e áreas do entorno com base em dados de pesca, registros da literatura e múltiplas técnicas de amostragem, incluindo a técnica de vídeo rotacional subaquático usada pela primeira vez no Brasil. Apresentamos um inventário de 282 espécies de peixes representando 91 famílias, com 21 novos registros para área de estudo, incluindo uma espécie não nativa (Heniochus acuminatus). Além disso, nossos resultados mostram um nível de endemismo moderado da província brasileira (aproximadamente 6,0%), sendo 10,5% das espécies classificadas em uma das categorias ameaçadas da IUCN. Nossos esforços mostram o cenário da biodiversidade de peixes e sua distribuição nas ilhas costeiras mais de 10 anos após o estabelecimento do Monumento Natural das Ilhas Cagarras, reforçando a importância de programas de pesquisa de monitoramento para a gestão desta Área Marinha Protegida e suas águas adjacentes, que desempenham papel fundamental para a pesca artesanal.

Abstract Coastal islands of Grande Rio, located south Rio de Janeiro and Maricá cities have been under multiple anthropogenic impacts. Despite these problems, these insular systems shelter a high diversity of fish species. Reef fishes are essential components of tropical marine coastal communities, also providing food and income for millions of people around the world. In this work, we generated an updated checklist from Cagarras Islands Natural Monument and surrounding areas based on fisheries data, literature records and multiple sampling techniques, including the Submersible Rotating Video technique, used for the first time in Brazil. We present an inventory of 282 fish species representing 91 different families, with 21 new records for the study area, including a non-native species (Heniochus acuminatus). In addition, our results show a moderate endemism level for the Brazilian province (approximately 6.0%), while 10.5% of species are assigned to one of IUCN’s threatened categories. Our efforts show the fish biodiversity scenario and their distribution on coastal islands more than 10 years after the Cagarras Islands Natural Monument establishment, reinforcing the importance of monitoring research programs for the management of this Marine Protected Area and surrounding waters, that play a key role for artisanal fisheries.

Abstract The ovulation mechanism is one of the fascinating physiological processes in reproductive biology in mammals. From the reproductive point of view, the species have been classified as spontaneous or induced ovulators. Although the release of GnRH followed by the preovulatory LH surge is shared between both types of ovulation, the stimulus to initiate GnRH release varies between both categories. In spontaneous ovulators, ovulation depends on the systemic concentration of ovarian steroids, however, in induced ovulators, different stimuli such as copulation, environmental, and social cues can facilitate or induce ovulation regardless of the increases in systemic estradiol concentration. In this review, we document evidence that a male-derived protein is the main factor responsible for inducing ovulation and also modulating the ovarian function in the domestic South American camelid, the llama. The neurotrophin beta-Nerve Growth Factor (β-NGF) is the principal factor present in the semen of llamas responsible for inducing ovulation in this species. After the intrauterine deposit of semen during mating, β-NGF is absorbed through the endometrium to reach the circulatory system, where it reaches the hypothalamus and stimulates GnRH release. The potential site of action of this neurotrophin at the brain has not been elucidated, however, hypotheses are raised that the factor may cross the blood-brain barrier and stimulate upstream neuronal networks that lead to the stimulation of GnRH-secreting neurons. It is possible that β-NGF could be sensed at the median eminence without crossing the blood-brain barrier. Finally, it has been observed that this factor is not only a powerful stimulator of ovulation but also has a luteotrophic effect, resulting in the development of a corpus luteum capable of secreting more progesterone when compared to other ovulation-stimulating analogues. mammals view ovulators categories steroids however copulation environmental review malederived male derived camelid llama betaNerve beta Nerve βNGF β NGF (β-NGF mating system elucidated bloodbrain blood GnRHsecreting neurons Finally effect ovulationstimulating stimulating analogues

Resumo: A lagosta vermelha tem um importante papel comercial no Brasil, porém, uma tendência de queda na produção de lagostas devido a sobrepesca tem sido observada e há também uma desvalorização do produto no mercado internacional devido à instabilidade no comprimento das lagostas comercializadas. Aqui no Brasil, detectamos dois problemas em relação à lagosta vermelha: (1) De acordo com estudos recentes, existem diferenças genéticas e morfológicas entre as populações caribenha e brasileira e; (2) Atualmente a legislação não considera os múltiplos estoques prováveis da espécie. Desta forma, os períodos de defeso sazonais não consideram os diferentes estoques, o que tem implicações diretas no manejo e na conservação. Logo, o reconhecimento da lagosta vermelha do Brasil como Panulirus meripurpuratus e investimentos em pesquisas biológicas e populacionais são fundamentais pra facilitar seu manejo considerando diferenças regionais nos seus estoques.

Abstract: The Spiny Red Lobster has an important commercial role in Brazil. However, a downward trend in the production of lobsters due to overfishing has been observed and there is also a devaluation of the product in the international market due to the instability in the size pattern of lobsters commercialized. Here in Brazil we detected two issues regarding the Spiny Red Lobster: (1) According to recent studies, there are genetic and morphological differences between Caribbean and Brazilian populations, which may be considered different species and; (2) Current legislation, such as seasonal closures, does not consider the multiple probable stocks of the species, which have direct implications in management and conservation. Thus, the recognition of the Spiny Red Lobster from Brazil as Panulirus meripurpuratus and investments on population and biological research are essential to improve its management considering regional stock differences.

Abstract In order to contribute to the management of small-scale trawling fishing of the Xiphopenaeus kroyeri shrimp, the aim of this study was to evaluate the local ecological knowledge (LEK) and the conservationist attitudes of artisanal fishers in four fishing communities along the central Brazilian coast. This study was based on 80 ethnographic interviews conducted in two communities are in the state of Bahia (Santa Cruz Cabrália and Barra de Caravelas) and two communities in the state of Espírito Santo (Barra Nova and Anchieta). The fishers present knowledge compliance with literature, except in aspects reproductive of the shrimp and are willing to exchange knowledge with researchers. The mean attitude index of the fishers was 0.65. Education activities should focus on the reproductive biology of shrimp to include fishing communities in the drafting of legislation about closed season period, as this issue is directly related to possible divergences between fishers do not adhere to them. The results suggest that, dialogue and knowledge exchange is necessary among the stakeholders, including the fishers, scientists and managers, who are responsible for the elaboration of management measures.

Abstract The tribe Xyleborini (Curculionidae: Scolytinae) is an important group of ambrosia beetles. In recent years, it has generated considerable interest around the world due to the economic importance of some of its species. In the case of Mexico, there is a need to develop relevant tools for their correct identification. Here we provide a series of illustrated keys for females of genera and species of the tribe Xyleborini present in Mexico. We include keys for females of 9 genera and 56 species of Xyleborini, as well as a brief diagnosis, current distribution in the Mexican states and a photographic guide with the most important characters of each species. Twenty species of the genus Xyleborus Eichhoff are included, with X. torquatus Eichhoff and X. vagabundus Schedl considered as distinct species from X. volvulus (Fabricius). Xyleborus discretus Eggers is transferred to the genus Euwallacea Hopkins.

Abstract: This article aims to establish a dialogue between notions of development and recognition. The epistemic foundation of this discussion is framed in Ricoeur consideration that bets on the individual's condition as a capable man or "I can", with the power to speak, act and impute actions, basic conditions to face the path to recognition of himself. However, these individual capacities to act, on the collective level, extend to social practices of mutual recognition based on an ethical principle, from which, it is possible to identify three imperatives dialoguing with the notion of development: to tend towards the good life, in and with others, and with just institutions. It concludes by affirming that the crisis regarding the notion of development proper to modernity has given it the possibility of resignifying the approaches that exalt human capacities in the search for subjective well-being that are oriented towards the path of mutual recognition.

Resumen: El presente artículo se propone establecer un dialogo entre las nociones de desarrollo y de reconocimiento. La fundamentación epistémica de esta discusión se enmarca en la consideración de Ricoeur que apuesta a la condición del individuo como un hombre capaz o “un yo puedo”, con el poder de hablar, actuar e imputarse acciones, condiciones básicas para enfrentar el camino hacia el reconocimiento de sí mismo. Ahora bien, dichas capacidades individuales de obrar, en el plano colectivo se extienden hacia prácticas sociales de reconocimiento mutuo sustentadas bajo un principio ético, desde el cual, es posible identificar tres imperativos dialogantes con la noción de desarrollo: tender hacia la vida buena, en y con el otro y con instituciones justas. Se concluye afirmando que la crisis respecto de la noción de desarrollo propia de la modernidad ha dado a la misma la posibilidad de resignificar los enfoques que exaltan las capacidades humanas en la búsqueda de un bienestar subjetivo que se orienten hacia el camino del reconocimiento mutuo.

ABSTRACT A large number of fish species use the mangrove mainly due to food availability and protection against predators. The knowledge of temporal and spatial dynamics of ichthyofauna allows us to identify patterns of occupation of this ecosystem and to support the assessment and preservation of local biodiversity. In this sense, samplings were conducted in 1988 at five areas of the Itacorubi River estuary, Santa Catarina Island. A total of 3,883 specimens were collected, distributed in 21 families and 41 species with the predominance of Cetengraulis edentulus, Mugil liza, Mugil curema, Genidens genidens, Mugil gaimardianus, Eucinostomus gula, Micropogonias furnieri, Pomatomus saltatrix and Sphoeroides testudineus. On average, abundances differed between seasons and sampled areas. Differences were detected between the fish faunas of fall and winter compared to summer and spring and between sampling sites. This study identified a fish assemblage in the mangrove of the Itacorubi River with a similar structure to other estuaries of southern Brazil.

ABSTRACT Streamprocessing platforms allow processing and analyzing realtime data. A recognized system for this purpose is the so-called Storm platform, an open-source system for distributed computing, which is a scalable, fast and, fault-tolerant. The Storm platform may be deployed on a large number of processors. However, determining the proper number of processors that are suitable to execute a given Storm based software application is a challenging task, especially if the application is intended to serve a very large user community. One way of solving this is by employing a simulation model that allows the evaluation of its performance under different workload scenarios. In this paper, a simulation model of a Storm application using the DEVS formalism is presented, then, an equivalent model is described using Timed Automata (TA). Throughout a procedure called "Bisimulation", it is checked that both models are effectively equivalent. Finally, the model defined using TA is formally verified evaluating its properties, proving that the simulation model has the same behavior as the real applications.

RESUMEN Las plataformas de procesamiento de permiten la manipulación y análisis de datos en tiempo real. Un sistema reconocido para este propósito es la llamada plataforma Storm, que es un sistema para computación distribuida, de código abierto, escalable, rápido y tolerante a fallos. La plataforma Storm puede ser desplegada sobre sobre un gran número de procesadores. Sin embargo, la determinación del número apropiado de procesadores que son necesarios para ejecutar adecuadamente aplicaciones de software para Storm no es una tarea fácil ni simple, especialmente si la aplicación está diseñada para ser usada por un gran número de usuarios. Una forma de resolver este problema es mediante un modelo de simulación que permita evaluar su rendimiento usando diferentes escenarios de cargas de trabajo. En este artículo, se presenta un modelo de simulación de una aplicación Storm usando el formalismo DEVS, posteriormente se define un modelo equivalente usando Autómatas Temporizados (AT). Mediante un proceso denominado "bisimulación" se comprueba que ambos modelos sean efectivamente equivalentes. Finalmente, el modelo descrito usando AT es verificado formalmente evaluando sus propiedades, demostrando que el modelo de simulación posee el mismo comportamiento que la aplicación real.

Resumo Este artigo discute a relação entre corpo e limite na obra de Michel Foucault, notadamente em textos que figuram às margens de sua interpretação canônica. A discussão sobre o corpo está presente em diversos momentos de sua obra e ganha destaque no final da década de 1970, quando a análise dos processos de subjetivação predomina em seu pensamento. A noção de limite, por sua vez, pode ser compreendida de diferentes maneiras dentro de sua obra. Em nossa análise, trataremos da utilização específica do termo “experiência-limite” em dois textos fora do “cânone”, confrontando-os com uma das abordagens mais diretas sobre o corpo que pode ser encontrada na obra foucaultiana: a rádioconferência O corpo utópico, de 1966.

Abstract This paper discusses the relation between body and limit in some texts from Michel Foucault´s work, especially those that appear on the margins of its canonical interpretation. The discussion about body is present in many moments of his work, and becomes an important element, especially in the analysis of the processes of subjectivity that prevailed in his thought at the end of the 1970´s. The notion of limit, in turn, can be understood in different ways in his work. In our approach, we will discuss the specific use of the term “limit-experience” in two texts that appears out of the canon, confronting them with one of the most direct approaches on body that can be found in Foucault’s work: a radio conference called Utopian body, issued in 1966.
