Derivation of Neural Precursors from Bovine Preimplantation Embryos
No full textInduction of neural differentiation from embryonic pluripotent stem cells (ES/EpiSc), both of mouse and primates, has been extensively published by several research teams. However, direct derivation of organized neuroectoderm in vitro from blastocyst stage embryos of rodents or primates has not been reported so far. Here we describe a method of direct neural differentiation from the inner cell mass cells of preimplantation bovine embryos, without the intermediate step of ES/EpiSc cells derivation (Lazzari et al., Stem cells 24:2514-2521, 2006). Proliferating neural precursors cells lines, and both central and peripheral nervous system derivatives, can be obtained providing a unique in vitro model of early neurulation events in mammals
Ramiro Guerra: caminante y testigo
No full textABSTRACT Introduction: The article presents an assessment of the figure of Ramiro Guerra y Sánchez given not only by its author but also by valuable intellectuals contemporary with Guerra such as Carlos Rafael Rodríguez, Raúl Roa, Medardo Vitier, Fernando Ortiz, Emilio Roig de Leuchsenring. Methods: In this study about Ramiro Guerra, a distinction of his intellectual productionis made along two main lines: the texts with pedagogical content and critical analysis to Cuban education and the historiographic essay. Results: Specifically, the author pauses in the analysis of two works considered «minor» within his historiographical task: Mudos Testigos (1948) and Por las veredas del Pasado (1957), which demonstrate the valuable contribution of Ramiro Guerra to the social, regional and rural family history in Cuba between the end of the 19.th century and the beginning of the 20.th century. Conclusions: The conclusions are aimed at placing Ramiro Guerra in a very important position within the Cuban intelligentsia of the 20.th century and to understand his validity in Cuban historical studies.RESUMEN: Introducción: En el artículo se presenta una valoración de la figura de Ramiro Guerra y Sánchez dada no solamente por el autor del trabajo sino por valiosos intelectuales contemporáneos con Guerra como Carlos Rafael Rodríguez, Raúl Roa, Medardo Vitier, Fernando Ortiz, Emilio Roig de Leuchsenring. Métodos: En este estudio de Ramiro Guerra se hace una distinción de su producción intelectual en dos grandes líneas: los textos de contenido pedagógico y análisis crítico de la educación cubana y el ensayo historiográfico. Resultados: De manera puntual, el autor se detiene en el análisis de dos obras consideradas «menores» dentro de su faena historiográfica: Mudos testigos (1948) y Por las veredas del pasado (1957), las que demuestran la valiosa contribución de Ramiro Guerra a la historia social, regional y de la familia rural cubana entre finales del siglo XIX e inicios del siglo XX. Conclusiones: Las conclusiones están encaminadas a situar a Ramiro Guerra en un lugar importantísimo dentro de la intelectualidad cubana del siglo XX y a comprender su vigencia en los estudios históricos cubanos

Exploration of biomaterials design space through combinatorial and high-throughput approaches: tyrosine-derived polycarbonates as a case study
No full textThe use of combinatorial and high-throughput approaches in the design and exploration of materials space has been gaining increasing acceptance in recent years. While these methods have been successfully employed in the development of materials for the fields of electronics and optics, only a few examples exist within the field of biomaterials science. While there is a clear need for complex polymer structures that can be tailored for specific applications, most current research is being done on the basis of "trial and error" approaches that simply cannot keep up with the demand for novel technologies.
As part of the work involved in this thesis, the number of viable biomaterial candidates was increased by varying the chemical composition of tyrosine-derived monomers in two positions, namely the backbone and pendent chain. The resulting monomers proved to have different physical and chemical properties, derived from small modifications to their chemical structure.
In order to effectively synthesize several compositions of tailored tyrosine-derived polycarbonates, automated synthetic procedures were created and evaluated in a modern robotic platform. The challenges involved in the automation of polycondensation reactions, such as liquid handling, dropwise addition, and toxic chemical handling, were addressed successfully. A considerable amount of time was saved in comparison to manual methods when generating large polymer libraries.
In order to study structure-property relationships, the mass-per-flexible-bond principle was used to quantitatively explain the large range of glass transitions observed in a library of polymers containing homo-, co-, and terpolymers. Within this context, the information gathered in this thesis is expected to be used as a guideline for the rational design of polymers for specific applications.
The information derived from this work made it possible to ascertain that future research can certainly benefit from the automated parallel synthesis methods developed during it, as well as from the linear relationships found. It is expected for the research done in this thesis to have a definite impact not only on the use of combinatorial and high-throughput approaches in polymer science, but also on the informatics aspect involved.Ph.D.Includes bibliographical references (p. 158-165)by Ramiro Rojas Escontrilla
Luis Ramiro Beltrán: pensador canónico de la Comunicación latinoamericana
No full textLuis Ramiro Beltrán Salmón, who died on July 11th, 2015, was the most important
Bolivian thinker of communication and the standard-bearer of the Latin American
utopia of communication for democratic development with social justice and sovereignty.
He began being a journalist when he was only 12 years old and at his 40 became
a reference point for the specialized critical thinking in the region which basis
helped to build with his intellectual work. His major concerns were communication
and development, communication and democracy, and finally communication research.
His proposals about National Communication Policies, Horizontal Communication
and the Communicology of Liberation are still valid, fact that makes
him into a classic author in the Communication field.Luis Ramiro Beltrán Salmón, fallecido el 11 de julio de 2015, fue el mayor pensador boliviano de la Comunicación y el abanderado de la utopía latinoamericana de la comunicación para el desarrollo democrático con justicia social y soberanía. Se hizo periodista a los 12 años de edad y a los 40 se convirtió en un referente del pensamiento crítico especializado de la región cuyas bases contribuyó a construir con su obra intelectual. Sus grandes preocupaciones fueron la comunicación y el desarrollo, la comunicación y la democracia y la investigación comunicacional. Sus propuestas relativas a las Políticas Nacionales de Comunicación, la Comunicación Horizontal y la Comunicología de Liberación tienen plena vigencia, lo que hace de él en un autor clásico del campo de la Comunicación
La defensoría del lector en Bolivia
No full textA few months ago a self-regulated institution of press activities emerged in Bolivia: the defender of the reader. The Bolivian Communication Specialist, Luis Ramiro Beltrán, talks profoundly about the issue in this presentation, read in public at his installation as defender of the reader in the Group of the Leading Press of his country. He makes us see in it the immense power of the media, that apparently has neither barriers nor brakes, except those that journalists might impose through ethics, a barrier which according to the author must be impervious to excesses and absurdities.Hace unos meses surgió en Bolivia una institución autorregulatoria de la actividad de la prensa escrita: la defensoría del lector, de la que nos habla en profundidad el comunicólogo boliviano Luis Ramiro Beltrán en esta ponencia, leída en el acto público de su iniciación como defensor del lector en el Grupo de Prensa Líder de su país. En ella nos hace ver el poder inmenso de los medios, que no tiene aparentemente barreras ni frenos, excepto los que pueden ponerles los periodistas a través de la ética, muralla que según el autor tiene que ser inexpugnable para los excesos y despropósitos

Análise sobre a obra Latifúndio, Escravidão e Dependência Econômica de Ramiro Guerra
No full textThis work aims to analyze the work of Ramiro Guerra (Latifundia, slavery and economic dependence), one of his main works dealing with the region of Barbados located in the Lesser Antilles in Central America. Thus, the analysis shows how Ramiro Guerra demystifies a whole theory regarding the substitution of the work of the small owner for the cheap labor of the slave. The same author emphasizes that this substitution was not due to a question of races or of climate or even of the superiority of the human will. But due to a purely social and economic cause: the destruction of small property by the sugar estates and the consequent emigration of a social class that would be expelled in a "voluntary" way due to lack of work. Thus, according to Guerra's analysis, the analysis emphasizes that it was not the Antillean climate that drove out the white servants but the capitalist sugar company that would settle in the region, annihilating the small property and eliminating the independent cultivator and converting the robust communities with their own lives in mere low-wage workshops, all for the benefit of metropolises. And also the consequences of this sugar trade in Cuba with the same consequences of the destruction of small-scale agriculture.
JEL Classification: Q1.Este trabalho tem como objetivo analisar a obra de Ramiro Guerra (Latifúndio, escravidão e dependência econômica), uma das suas principais obras que trata da região de Barbados localizada nas Pequenas Antilhas na América Central. Assim, a análise mostra como Ramiro Guerra desmistifica toda uma teoria em relação à substituição do trabalho do pequeno proprietário pela mão de obra barata do escravo. O mesmo autor ressalta que essa substituição não foi devido a uma questão de raças ou de clima ou até mesmo da superioridade da vontade humana. Mas sim, devido a uma causa puramente social e econômica: a destruição da pequena propriedade pelo latifúndio açucareiro e pela conseguinte emigração de uma classe social que seria expulsa de forma “voluntária” devido à falta de trabalho. Dessa forma, a análise de acordo com o pensamento de Guerra, enfatiza que não foi o clima antilhano que expulsou os servos brancos, mas sim a empresa açucareira capitalista que se instalaria na região, aniquilando a pequena propriedade e eliminando o cultivador independente e convertendo as comunidades robustas com vidas próprias em meras oficinas de trabalho com salários baixos, tudo em prol das metrópoles. E também as consequências desse comércio açucareiro em Cuba trazendo as mesmas consequências de destruição da pequena agricultura.

Late evaluation of patients with schistosomiasis, not previously submitted to surgical treatment, after eradication of bleeding esophageal varices by endoscopic sclerotherapy
No full textO autor avaliou, num periodo tardio, trinta e sete doentes com a forma hepatosplenica compensada da esquistossomose e antecedente de hemorragia varicosa, que nao haviam sido submetidos previamente ao tratamento cirurgico da hipertensao portal, e cujas varizes de esofago foram erradicadas por escleroterapia endoscopica, no setor de Endoscopia Digestiva da Disciplina de Gastroenteroiogia Cirurgica da UNIFESP, entre janeiro de 1986 e dezembro de 1994. Constituiram a casuistica 21 pacientes do sexo masculino e 16 do sexo feminino, com idade variando de 17 a 66 anos, sendo a mediana 36 anos. O periodo de acompanhamento apos a erradicacao das varizes variou de 36 a 126 meses, sendo a mediana 59 meses. A tecnica de escleroterapia empregada foi a de injecoes intravaricosas de oleato de monoetanolamina a 3 por cento , realizadas por diferentes examinadores. O numero de sessoes ate que o exame endoscopico evidenciasse a erradicacao das varizes variou de quatro a nove, com a mediana de seis sessoes. O periodo de tempo observado entre o inicio do tratamento endoscopico e a observacao do desaparecimento das varizes variou de tres a 17 meses, sendo a mediana de 7 meses. A hemorragia digestiva foi observada durante o tratamento endoscopico em oito pacientes (21,6 por cento ), sempre controlada com medidas clinicas e endoscopicas. Durante o periodo de acompanhamento apos a erradicacao 62,2 por cento dos pacientes apresentaram varizes esofagicas neoformadas necessitando de novas intervencoes endoscopicas. Na maior parte dos doentes esse diagnostico foi realizado efetivamente e nao determinou complicacoes. A ocorrencia de hemorragia digestiva apos a erradicacao das varizes foi observada em 18,9 por cento dos pacientes, sendo a maior parte causada por cordoesvaricosos neoformados, tambem controlados com medidas clinicas e endoscopicas. Os episodios hemorragicos foram observados apenas ate 0 59º mes apos a erradicacao, sendo todos de leve intensidade, sugerindo que apos esse periodo os pacientes que sao acompanhados com regularidade teriam menor risco de apresentarem novo sangramento. Nao houve nbenhum obito no periodo de acompanhamento e nenhum dos pacientes foi submetidos ao tratamento cirurgico da hipertensao portal. A avaliacao tardia deste grupo de doentes selecionados permitiu as seguintes conclusoes, validas para este grupo selecionado: 1) a maioria dos pacientes apresentou varizes esofagicas neoformadas num perio...(au)BV UNIFESP: Teses e dissertaçõe
