Human bertiellosis in Goiás, Brazil: a case report on human infection by Bertiella sp. (Cestoda: Anoplocephalidae)

The authors report on a new case of human Bertiellosis in a 2-year old female patient who was born in Goiânia-Goiás (Brazil) and has had history of permanent dwelling in an area frequently visited by simians in Mato Grosso (Brazil). At the time of diagnosis the patient showed inappetence, abdominal pain, and loss of weight. Eggs and proglottids were found in her stool and were identified as Bertiella sp. The objective of this report is to register the third case of human Bertiellosis in Brazil, characterizing one more case of helminthic zoonosis.

Cuerpos Intervenidos : Experiencias corporales diferenciadas de la feminidad y el cáncer de seno

Este proyecto de investigación se enfoca en estudiar la configuración de las feminidades en mujeres que han pasado por la experiencia del cáncer de seno. Teniendo en cuenta que cada una de ellas tiene una trayectoria social diferente que determina el desarrollo de la feminidad y de la experiencia de la enfermedad. La metodología que se utilizó dentro de la investigación fue de carácter etnográfico, ya que se pretendió dar cuentan de la experiencia de la enfermedad, la corporalidad y la subjetividad.

Morphometry and histochemistry of the Rectus abdominis muscle fibers of tufted capuchin monkeys (Cebus apella Linnaeus, 1758)

The phylogenetic proximity of primates to humans, along with their behavioral, biochemical, and anatomical similarities, make such animals more interesting experimental models for biomedical researches, as compared to classical laboratory animals. Another aspect that has called the attention of researchers is the differentiated quadrupedalism present in some primates. The tufted capuchin monkey uses the ground and tree branches as its support for locomotion, showing various postures while performing this task. On the basis of this information, we have decided to study the rectus abdominis muscle of the tufted capuchin monkey, with the following goals: the frequency and area of fiber types; its possible compartmentalization; and identify if this muscle is better adapted to phasic or postural activities. To do this, samples were removed from 4 regions of the rectus abdominis muscle of 6 adult male tufted capuchin monkeys, and were submitted to reaction with m-ATPase, (with alkaline and acid pre-incubation), NADH, and H.E.. Results showed: a statistically significant difference (P<0.05) for both frequency and area, between fiber types FG and FOG and FG and SO, but did not show a statistically significant difference between fibers FOG and SO, in all studied regions; similarity in frequency and area of a same fiber type (FG, FOG, and SO) among the studied regions. Based on these data, it was concluded that: the rectus abdominis muscle of the tufted capuchin monkey does not show fiber compartmentalization, since the distribution and size patterns of the different fiber types are similar in the studied regions; there is a predominance of fast twitch fibers (FG + FOG) over slow twitch fibers (SO), for frequency and area, which characterizes the muscle as being more dedicated to phasic than to postural activities. © 2006 Sociedad Chilena de Anatom.

Emergence of the ZNF91 Krüppel-associated box-containing zinc finger gene family in the last common ancestor of anthropoidea.

The ZNF91 gene family, a subset of the Krüppel-associated box (KRAB)-containing group of zinc finger genes, comprises more than 40 loci; most reside on human chromosome 19p12-p13.1. We have examined the emergence and evolutionary conservation of the ZNF91 family. ZNF91 family members were detected in all species of great apes, gibbons, Old World monkeys, and New World monkeys examined but were not found in prosimians or rodents. In each species containing the ZNF91 family, the genes were clustered at one major site, on the chromosome(s) syntenic to human chromosome 19. To identify a putative "founder" gene, > 20 murine KRAB-containing zinc finger protein (ZFP) cDNAs were randomly cloned, but none showed sequence similarity to the ZNF91 genes. These observations suggest that the ZNF91 gene cluster is a derived character specific to Anthropoidea, resulting from a duplication and amplification event some 55 million years ago in the common ancestor of simians. Although the ZNF91 gene cluster is present in all simian species, the sequences of the human ZNF91 gene that confer DNA-binding specificity were conserved only in great apes, suggesting that there is not a high selective pressure to maintain the DNA targets of these proteins during evolution.

Regional specialization in pyramidal cell structure in the visual cortex of the galago: An intracellular injection study of striate and extrastriate areas with comparative notes on New World and Old World monkeys

Recent studies have revealed marked differences in the basal dendritic structure of layer III pyramidal cells in the cerebral cortex of adult simian primates. In particular, there is a consistent trend for pyramidal cells of increasing complexity with anterior progression through occipitotemporal cortical visual areas. These differences in pyramidal cell structure, and their systematic nature, are believed to be important for specialized aspects of visual processing within, and between, cortical areas. However, it remains unknown whether this regional specialization in the pyramidal cell phenotype is unique to simians, is unique to primates in general or is widespread amongst mammalian species. In the present study we investigated pyramidal cell structure in the prosimian galago (Otolemur garnetti). We found, as in simians, that the basal dendritic arbors of pyramidal cells differed between cortical areas. More specifically, pyramidal cells became progressively more spinous through the primary (V1), second (V2), dorsolateral (DL) and inferotemporal ( IT) visual areas. Moreover, pyramidal neurons in V1 of the galago are remarkably similar to those in other primate species, in spite of large differences in the sizes of this area. In contrast, pyramidal cells in inferotemporal cortex are quite variable among primate species. These data suggest that regional specialization in pyramidal cell phenotype was a likely feature of cortex in a common ancestor of simian and prosimian primates, but the degree of specialization varies between species.

Difusión teatral del transformismo: El caso de "Les deux Jockos", 1825

Durante el siglo XIX el transformismo irrumpe en el panorama científico, una irrupción cuyas implicaciones filosóficas y sociales se traducen, entre otros, en obras teatrales en las que la temática refleja la difusión de estas nuevas ideas. Les deux Jockos, de 1825, ejemplifica ese grupo de representaciones que ponen en escena el debate transformista en una sociedad todavía dominada por los preceptos fijistas defendidos desde las instituciones y las élites sociales de la época. Así pues, el análisis de la obra permitirá desvelar aquellos elementos relacionados con el nuevo paradigma de naturaleza propuesto, al tiempo que evidencia la capacidad de influencia de la realidad histórica, social y cultural sobre el género teatral.

Colectivos sociales y ciborgs: hacia una lectura feminista de los drones

Este artículo analiza el papel de los drones en la emergencia de nuevas formas de participación política e impugnación del poder por parte de colectivos sociales. El artículo plantea una lectura feminista de los drones como ciborgs (humanos-máquinas) para explorar las agencias distribuidas entre actores humanos y no humanos con el propósito de visibilizar las relaciones de poder y analizar la configuración de contra-realidades. Se presentan ocho casos de colectivos sociales que, con la ayuda de un dron, disputan el poder de gobiernos, empresas transnacionales además de desempeñar innovadoras intervenciones públicas.

Digitizing dissent: cyborg politics and fluid networks in contemporary Cuban activism

Communication technologies shape how political activist networks are produced and maintain themselves. In Cuba, despite ideologically and physically oppressive practices by the state, a severe lack of Internet access, and extensive government surveillance, a small network of bloggers and cyberactivists has achieved international visibility and recognition for its critiques of the Cuban government. This qualitative study examines the blogger collective known as Voces Cubanas in Havana, Cuba in 2012, advancing a new approach to the study of transnational activism and the role of technology in the construction of political narrative. Voces Cubanas is analyzed as a network of connections between human and non-human actors that produces and sustains powerful political alliances. Voces Cubanas and its allies work collectively to co-produce contentious political discourses, confronting the dominant ideologies and knowledges produced by the Cuban state. Transnational alliances, the act of translation, and a host of unexpected and improvised technologies play central roles in the production of these narratives, indicating new breed of cyborg sociopolitical action reliant upon fluid and flexible networks and the act of writing. 

Configuración y dislocación de los espacios de trabajo

Esta tesis se presenta como el inicio de una larga reflexión que se pregunta por los espacios de trabajo, sus significados, las relaciones y decisiones que los configuran y a la vez ellos configuran, y la manera como se transforman, transgreden y superan a través de la adopción de las tecnologías. Los resultados que aquí se presentan parten del análisis de once (11) organizaciones ubicadas en Bogotá que acompañé durante el 2014 y 2015 en sus procesos de cambio de oficina.
