Making: the invisible visible

In this book essay I argue that modern and contemporary works of art (i.e. paintings, photographs, films, and videos) really ought to retrieve something of their auratic-character, which turns the physical toward the metaphysical, the material toward the immaterial, the visible toward the invisible - making artworks, ‘things among things, something other than [a] thing’ (Theodor W. Adorno, Aesthetic Theory, 86). There is, perhaps, an aura to art or art is a medium or a conduit or a technology for rediscovering and reproducing aura, which makes it something other than a mere thing. Such works of art are constitutively enigmatic, a certain form of magic making: they (re-)distribute the visible and the invisible, they (re-)configure appearance and disappearance. Such works of art may become visual events, which begin an education in and through (dis-)appearances. To achieve this end, I detail Theodor W. Adorno’s and Walter Benjamin’s respective theories of (art’s) aura in the age of technological reproducibility, which I relate to Jacques Rancière’s more recent discussion of the ‘pensive image,’ and I focus my reading on a number of works by Susan Hiller (photographs), John Constable (paintings), Alfred Stieglitz (photographs), and Tacita Dean (photograph and 16mm film).

Amor intellectualis diaboli

An essay on love and liberty in the writings of Gillian Rose, Marquis de Sade, Max Horkheimer and Theodor W. Adorno, written in response to the following provocation: "Encore un effort. A banderole publicitaire carries the breathless descriptions of the new fashions for 1968, when anything goes and details place the accent on this or that part of the body and its adornment: a pair of shoes that come off in a struggle, for example, the heel of one snapped off; a striking checked shirt, with two buttons undone; a light-coloured trench coat (perfect for a May day); a blouson-style jacket that allows easy freedom of movement; place casual slacks worn with an ankle boot. Beauty is in the streets as fashion becomes democratic (or so say the houses of haute couture), while the philosopher of the boudoir extorts us once again to make an effort if we wish to be republicans. Here, to an assembled crowd of sensitive men and women, which petit-maitre or dangerous man of principles would suggest that the only moral system to reinforce political revolution is that of libertinage, the revenge of nature's course against the aberrations of society?"

NEUREGULINS 1-ALPHA AND 1-BETA ON THE REGENERATION THE PERIPHERAL NERVES

Objective: To evaluate the effect of the neuregulins 1-alpha and 1-beta on the regeneration the sciatic nerves of male adult C57BL/6J mice, using the tubulization technique. Methods: Eighteen animals were used, divided into three groups. A polyethylene prosthesis was implanted in a 4.0 mm defect of the left sciatic nerve, as follows: group 1 containing only purified collagen (Vitrogen (R)); group 2, collagen with neuregulin 1-alpha; group 3, collagen with neuregulin 1-beta. The control group consisted of six segments of right sciatic nerves. After four weeks, the animals were sacrificed. A segment from the midpoint of the nerve regenerated inside the prostheses was extracted; histological sections were standardized, and slides were made up for histomorphometric analysis. Results: the results were statistically compared using the Tukey multiple comparisons test and The Student`s t test. The animals treated with neuregulins had greater numbers of myelinized axons, with a statistically significant difference in relation to the collagen-only group. There was no statistical difference between the neuregulin 1-alpha and 1-beta groups. Conclusion: The addition of neuregulins provided a significant increase in the number of myelinized fibers.

Morangos mofados, de Caio Fernando Abreu : melancolia e crítica social

Este trabalho consiste em uma leitura da obra Morangos mofados, de Caio Fernando Abreu, publicada em 1982. O objetivo da pesquisa é desenvolver uma leitura crítica de contos da antologia que englobe uma articulação entre forma literária e conteúdo social. O estudo parte de uma recuperação dos textos críticos sobre a produção do autor e em seguida apresenta um caminho de leitura para os contos do livro a partir das relações entre literatura, história e sociedade. Em sua segunda parte, a investigação enfoca elementos teóricos sobre a fragmentação formal da narrativa e sobre a melancolia. Entre os autores consultados para fundamentação estão Theodor Adorno, Walter Benjamin, Sigmund Freud e Julia Kristeva. A terceira parte constitui-se da análise de textos de Caio Fernando Abreu, a qual é elaborada a partir da observação à fragmentação formal dos contos e à perspectiva melancólica que transparece nas narrativas, pois esses são elementos que configuram a crítica social da produção literária investigada e a relação da obra com o seu contexto de produção. Os contos selecionados para essa leitura são “Os sobreviventes”, “Pêra, uva ou maçã?”, “Aqueles Dois” e “Morangos mofados”. O trabalho também contempla uma reflexão acerca dos estudos críticos sobre o escritor e a sua obra, apontando a necessidade de se desenvolver uma leitura do texto a partir da articulação entre forma literária e conteúdo social.

A educação vista pelo olhar do filósofo Adorno

Adorno que foi um filósofo alemão do século passado propõe uma reflexão dos educadores sobre a possibilidade de uma reincidência de Auschwitz, que foi um dos principais campos de concentração na Segunda Guerra Mundial. Para ele a educação deveria estabelecer práticas que combatessem a possibilidade da volta de um clima cultural favorável aos campos de concentração. É nesse sentido, que para Adorno aquele professor que tem uma posição autoritária de modo que os alunos não se sintam estimulados a intervir sala de aula, cria uma situação em que o aluno pode passar a odiar o professor, ou seja, essa ideia de que os professores precisam ser rígidos para formar o caráter dos alunos é uma posição errada, pois acaba propiciando ao ódio e ao ressentimento. Outro ponto trabalhado por Adorno no livro Educação após Auschwitz é como, cada vez mais, as pessoas tendem a sentir mais afeto pelas coisas do que por outras pessoas, o que ele vai chamar de consciência coisificada.

A ideologia da encenação: uma análise dos aspectos cênico/ideológicos da encenação produzida pela indústria cultural

The research that led to this dissertation adopted a set of scenic/ideological aspects inherent to the productions of the Culture Industry as its object of research. The intellectual output of Theodor W. Adorno and Max Horkheimer underscored the approaches on this subject, since it provides the same set of scenic/ideological features to be explored because, according to the authors, scenes produced by the culture industry are linked to the dominant ideology, since they act in favor of maintaining the status quo. The first objective was the definition this set of features inherent to the scene produced by the culture industry, through the exploration of literature produced by Adorno and Horkheimer, so it was possible to define a set composed of nine elements: Construction of characters as characteristic types; Stereotypes; Naturalization of Stereotyped language; Simplistic playwriting; Reuse dramatic formula; Love and sexuality as themes of plots; Utilization of tragic element; Objetive representation; Approximation of fiction and reality. The second goal was the analysis of scene produced by the culture industry nowadays, so that it was possible to verify if any scenic/ideological aspects indicated by Adorno and Horkheimer in the mid-twentieth century were present among the productions from this beginning of the twenty-first century. Through the analysis of three soap operas produced in Brazil in 2012, it was found that the nine scenic/ideological aspects as indicated by Adorno and Horkheimer appeared in the observed productions. Additionally, a new scenic/ideological feature, not indicated by Adorno and Horkheimer is present: the merchandising

Indústria cultural e forró eletrônico no Rio Grande do Norte

The present study aimed to understand how and to what extent the electronic forró, currently hegemonic in the music market in the state of Rio Grande do Norte, establishes and maintains relations of domination in the social contexts in which it is produced, transmitted and received. Based, in significant form-content, on the writings of the first generation of theorists of the so-called Frankfurt School (Critical Theory), particularly with Theodor W. Adorno, and systematically using the contributions of the Cultural Studies (from the Centre for Contemporary Cultural Studies of Birmingham) and of the sociology of Pierre Bourdieu, this study aimed to perform, in the fertile intersection of these references, a critical possibility of interpretation of the electronic forró predominantly spread in the state of Rio Grande do Norte. To this end, aiming at a better apprehension of the so-called capital circuits/culture circuits , this study resulted from a qualitative investment of research, based on structured interviews with musicians, entrepreneurs of the sector and music consumers, as well as on the analysis of the themes contained in the official discography of the electronic forró band called Garota Safada (Shameless Girl). As a general empirical conclusion, it was possible to infer that far from the significant presence of domination or mere prevalence of oppositions, there is a relational pluralism of forms of domination and ways of resistances present in the production and consumption of electronic forró, regardless of gender, age, income, education or place of residence. However, the artifices of the cultural industry has been shown to be efficient: from large-scale businessmen to small producers enabled by the so-called open markets . The currentness of the concept of cultural industry is based on the idea that its products are offered systematically (the systematic insistence of everything to everyone) and on the notion that its production primarily meets the administrative criteria of control over the effects on the receiver (capacity of prescription of desires). Thus, the Adornian reflection on the pseudo-individualization leads to the inference that even in some of the most apparent ways of negotiation and/or refusal regarding the consumption of forró, certain behaviors of the cultural industry still prevail both in the very (re)interpretation of the forró and in the choice of other music genres also standardized, rationalized and massified. Therefore, despite the absence of cause-effect relation and the recognition of the popular capacity of re-elaboration and contestation of the media consumption, some world views prevailing in relation to the electronic forró establish or, at least, support some hegemonic ideologies, especially those concerning the life style, consumption and genre relations (fun by all means). Therefore, due the massification of certain songs, some ways of dissemination of values, beliefs and feelings are potentially experienced from the electronic forró. So, it is presumable that in the current advance of the process of semiformation (Halbbildung), the habitus of a part of the youth from the state of Rio Grande do Norte reinforces and is reinforced by the centrality of the trinomial fun, love and sex present in the songs, emphasized in some constructive practices of sense and in certain flows of social significance

Ultrastructural Study of the Neuromuscular Junctions of Extensor Digitorum Longus Muscle (M. extensor digitorum longus) of the Mice

The neuromuscular junction of the extensor digitorum longus muscle of fingers was analyzed in 21 young (three months) and old (from six to 25 months) mice, from both genders. Morphologic changes were found throughout the mouse life, being more frequent and visible with aging. According with the data described in the literature consulted and the observations taken in this research, it becomes clear that a continuous process of morphological remodeling occurs in all neuromuscular ultrastructural junctions of the extensor digitorum longus muscle of fingers, during the life of the animal. Theses changes are characterized by figures of myelin in the cytoplasm of Schwann cells, pleomorphic and multivesiclar bodies, mitochondrias with morphologically altered crests in the axon terminal and degenerated junction folders. Coated vesicles are common in older animals and rare in young animals.

Das cinzas aos mafuás: infância e morte na lírica de Manuel Bandeira

Cet article étudie la poésie de l'enfance et de la mort de Manuel Bandeira, à partir de la relation entre l'expérience, le langage et le sens, afin de mettre en place une nouvelle perspective sur ce thème, qui sert de guide et structure son Estrela da vida inteira (1966). Pour cela, il faut introduire la notion de lyrique, discutée par Theodor Adorno, pendant la conférence Lírica e sociedade (1958), à promouvoir la compréhension du poète, comme c'est le cas de Bandeira, implique son art par le biais de la dimension négative face à une situation de fétichisation des choses, afin d'appréhender des expériences qui constituent la substance de la vie et l'essence de la poésie. À cette perspective de lyrique s ajoutent les concepts de l'enfance et de la mort, exploités par Giorgio Agamben, dans les oeuvres Infância e história (2005) et A linguagem e a morte (2006), étant largement favorables à la compréhension de la poétique de l'enfance chez Manuel Bandeira, comme une sorte de discours qui récupère l'idée d'expérience dans l actualité, en marquant la limite entre une expérience muette et une expérience de la langue, de même, la mort apporte des implications relatives à la négativité, comme une brèche par laquelle l'auteur explore la signification de sa lyrique et la«dénoue» des incrustations du monde réifié, pour être dans la défense du langage non contaminé par le clôturée qui entravent la conservation de la créature et la donnée originaire des choses . Cela culmine l aboutissement de la thèse, la conclusion d être la négativité la voie qui explicite, dans l oeuvre bandeirienne, la culture brésilienne non comme une totalité positivée dans une ethnie, classe ou nation, mais comme un langage qui reconstruit, avec lyrisme, le coloré mosaïque qui est le Brésil

Leprosy patients: neurotrophic factors and axonal markers in skin lesions

Neurotrofinas são fatores de crescimento com papel fundamental na fisiopatologia neural. Esses mediadores modulam funcionalmente fibras nociceptivas. Mudanças em sua expressão têm sido relacionadas à perda precoce da nocicepção na hanseníase. Este estudo investigou a expressão de NGF, BDNF e NT3 em nervos dérmicos de pacientes hansenianos. A caracterização de fibras nervosas não mielinizadas foi feita por p75NTR e marcadores axonais NF-L e PGP 9.5. Os parâmetros clínicos de dano neural foram avaliados por monofilamentos Semmes-Wenstein. Nossos achados demonstram diminuição de NGF nos pacientes dimorfos em comparação aos controles. Resultados similares foram observados para PGP 9.5 (dimorfos: p<0,001; virchowianos: p<0,05) e NF-L (virchowianos: p<0.05), sugerindo degeneração avançada das terminações nervosas na hanseníase multibacilar. Foi observada correlação positiva entre p75NTR e PGP 9.5, indicando associação entre células de Schwann e axônios em fibras nervosas não mielinizadas. Os resultados indicam que o desequilíbrio na expressão das neurotrofinas pode participar do dano neural periférico.

Caracterização de um modelo experimental de neuropatia em ratos diabéticos induzidos pela aloxana

Cem ratos norvégicus, machos, com aproximadamente 3 meses de idade foram distribuídos por sorteio em 2 grupos experimentais: Grupo Controle (GC): com 50 ratos sadios, não diabéticos e Grupo Diabético (GD): com 50 ratos diabéticos, induzidos pela aloxana, sem qualquer tratamento. Cada grupo foi dividido em 5 subgrupos com 10 ratos cada e sacrificados com 1, 3, 6, 9 e 12 meses de seguimento, respectivamente. Parâmetros clínicos (peso, ingestão hídrica e alimentar, e diurese) e laboratoriais (glicemia, glicose urinária e insulina) foram documentados em todos os momentos de avaliação. Um segmento do nervo ciático foi obtido de cada animal, em ambos os grupos, para estudo à MO. e ME. Alterações clínicas e laboratoriais significativas (P<0,01), compatíveis com diabetes grave, foram observadas em todos os animais do GD a partir do 4o dia após a indução. Ratos de ambos os grupos apresentaram alterações no número de fibras mielínicas e nos depósitos intraaxonais de glicogênio que não diferiram, estatisticamente, aos 1, 3 e 6 meses de seguimento. Entretanto, aos 9 e 12 meses, ratos do GD apresentaram diminuição significativa no número de fibras mielínicas, com aumento do número de fibras mielínicas de menor calibre, quando comparados com ratos do GC (P<0,05). Grânulos de glicogênio intraaxonais também foram mais acentuados em ratos do GD no 9o e 12o mês de seguimento. Não foram observadas diferenças na densidade de fibras amielínicas ou alterações ultraestruturais significativas entre os dois grupos, em relação aos espaços intraaxonais e endoneurais, bainhas de mielina e células de Schwann durante todo o estudo.

Apontamentos sobre ética e individualidade a partir da Mínima Moralia

O artigo reflete sobre os conceitos de ética e de individualidade a partir da Mínima Moralia de T. W. Adorno para pensar as dimensões ética e normativa da Psicologia. Para isso recupera alguns elementos históricos do conceito de ética segundo Aristóteles, Hobbes, Rousseau e Kant para esclarecer a reflexão adorniana. A partir desta faz-se uma crítica as noções de individualidade e de autonomia no âmbito da Psicologia.

Neurofibromin: a general outlook

Neurofibromin is a cytoplasmic protein that is predominantly expressed in neurons, Schwann cells, oligodendrocytes, astrocytes and leukocytes. It is encoded by the gene NF1, located on chromosome 17, at q11.2, and has different biochemical functions, including association to microtubules and participation in several signaling pathways. Alterations in this protein are responsible for a phacomatosis named neurofibromatosis type 1.
