O Grito das Imagens em Corpos que Sangram
No full text O objeto discursivo tomado em análise neste artigo configura-se por um fragmento cênico-artístico do longa-metragem O som ao redor (2012), de Kleber Mendonça Filho, pela mobilização do dispositivo analítico, tecido nos entremeios de Pêcheux, Lacan e Didi-Huberman, que toma o artístico como rasgadura da imagem (Lara, 2022, 2023a). Tal como uma tela artística viva, esse fragmento vai sendo pintado e descolorido na própria movência da imagem material que retorna tantas outras nos entrecruzamos da memória (Pêcheux, 2007), da memória social e da memória do corpo (Leandro-Ferreira, 2013), por fissuras/rasgaduras (Didi-Huberman, 2013) tecidas pelo artístico. O gesto de olhar para as minúcias nesse trabalho do artístico como materialização do jogo poético-político é o que possibilita analisar o grito enodado ao silêncio no funcionamento discursivo das imagens fílmicas, nas quais o esquecimento emerge como estilhaços que fissuram a memória na atualização do dizer. Como o grito retorna imagens que gritam e fazem gritar imagens mudas/mutadas no enodar de corpos (des)encontrados? No movimento da imagem histórico-bíblica do “Lavar as mãos.... (Mãos) sujas de sangue...” em funcionamento no corpus de análise, o efeito metafórico do jorrar água que verte sangue tensiona o social em suas contradições. Assim a imagem “visível” se abre à “imagem opaca e muda” (Pêcheux, 2007, p. 55) pelo trabalho do artístico como rasgadura, sendo (des)manchada por corpos que sangram. A mobilização desse dispositivo analítico, como gesto do analista, dá a ver que o artístico é estruturante da arte, logo, aberto à deriva, à alteridade, na inscrição material do real do discurso como resistência.
Palavras-chave: Artístico como rasgadura. Imagem opaca. Esquecimento na memória.

Redox-Responsive Nanocapsules for the Spatiotemporal Release of Miltefosine in Lysosome: Protection against Leishmania
No full textLeishmaniasis, a vector-borne disease, is caused by intracellular parasite Leishmania donovani. Unlike most intracellular pathogens, Leishmania donovani are lodged in parasitophorous vacuoles and replicate within the phagolysosomes in macrophages. Effective vaccines against this disease are still under development, while the efficacy of the available drugs is being questioned owing to the toxicity for nonspecific distribution in human physiology and the reported drug-resistance developed by Leishmania donovani. Thus, a stimuli-responsive nanocarrier that allows specific localization and release of the drug in the lysosome has been highly sought after for addressing two crucial issues, lower drug toxicity and a higher drug efficacy. We report here a unique lysosome targeting polymeric nanocapsules, formed via inverse mini-emulsion technique, for stimuli-responsive release of the drug miltefosine in the lysosome of macrophage RAW 264.7 cell line. A benign polymeric backbone, with a disulfide bonding susceptible to an oxidative cleavage, is utilized for the organelle-specific release of miltefosine. Oxidative rupture of the disulfide bond is induced by intracellular glutathione (GSH) as an endogenous stimulus. Such a stimuli-responsive release of the drug miltefosine in the lysosome of macrophage RAW 264.7 cell line over a few hours helped in achieving an improved drug efficacy by 200 times as compared to pure miltefosine. Such a drug formulation could contribute to a new line of treatment for leishmaniasis.A.

Do sangue que escrevivemos: epistemologias negro-femininas em “Só as mulheres sangram” de Lia Vieira
No full textFrom the reading and analysis of the book of short stories Only women Sangram, by Lia Vieira
(2011), using as a key to reading, concept and methodological path, writing, a concept by author
Conceição Evaristo (2008), this work proposes the concept I write with ẹ̀
jẹ̀
, ancestral blood that
runs through the veins, the bodies, the lives of black women in a very specific way. The study
is developed from the analysis of self-representation in black-female literature in the work. I
propose here, in a black ancestral understanding that we women are many, and our experiences
are many, however, beyond our crossings and subjectivities, the intersectional understanding
that our common experiences also occur socially brings us the perspective of this collective
agency, of that shared blood that is also black as the color of our skin, in our very specific ways
of bleeding. Lia Vieira brings a commitment to racial issues and shows this in her works by
proposing new ways of existing, rethinking existence and proposing new perspectives. Based
on this understanding, we will think of writing with 'jẹ̀ as an epistemological category of
Ancestrality, which disallows the signs that were imposed on us as epistemic violence, as Nilma
Lino Gomes (2010) brings us. Ancestry that is beyond what is traditionally understood as time,
because it does not follow a straight line, crosses the counts, meets and disperses at its
crossroads, it is time through time, here and yesterday crossed, spinning in a spiral, as Leda
Maria Martins (2002) brings us. Time, blood, life written in black and female are ancestral, as
must be our references, our epistemologies; and black-female literature is an extremely
important tool to collaborate in the dissemination of this awareness, of this life that is, as
Conceição Evaristo teaches us, committed to writing.A partir das leitura e análise do livro de contos Só as mulheres Sangram, da autora Lia Vieira
(2011), utilizando como chave de leitura, conceito e caminho metodológico a escrevivência,
conceito da autora Conceição Evaristo (2008), este trabalho propõe o conceito Escreviver com

jẹ̀
, sangue ancestral que perpassa de modo muito específico as veias, os corpos, as vidas de
mulheres negras. O estudo está desenvolve-se a partir da análise da autorrepresentação na
literatura negro-feminina na obra. Proponho, aqui, num entendimento ancestral preto de que
nós mulheres somos muitas, e muitas são as nossas vivências, porém, para além de nossos
atravessamentos e subjetividades, o entendimento interseccional de que nossas experiências em
comum também se dão socialmente nos trazem a perspectiva desse agenciamento coletivo,
desse sangue compartilhado que é também preto como a cor de nossa pele, nas nossas formas
muito específicas de sangrar. Lia Vieira traz um compromisso com questões raciais e mostra
isso em suas obras propondo novas formas de existir, repensando as existências e propondo
novos olhares. A partir desta compreensão, pensaremos escreviver com ẹ̀
jẹ̀ enquanto categoria
epistemológica de Ancestralidade, que desautoriza os signos que nos foram impostos como
violência epistêmica, como nos traz Nilma Lino Gomes (2010). Ancestralidade que está além
do que se entende tradicionalmente como tempo, porque não segue em linha reta, atravessa as
contagens, encontra-se e dispersa em suas encruzilhadas, é o tempo através dos tempos, o aqui
e o ontem atravessados, girando em espiral, como nos traz Leda Maria Martins (2002). O tempo,
o sangue, a vida que se escrevive feminina e preta são ancestrais, assim como precisam ser as
nossas referências, nossas epistemologias; e a literatura negro-feminina é uma ferramenta
importantíssima para colaborar na disseminação dessa consciência, dessa vida que está, como
nos ensina Conceição Evaristo, comprometida com a escrit

Die Türkei und das andere Europa : Phantasmen der Identität im Beitrittsdiskurs /
No full textDiese Studie analysiert das dialogische Zusammenspiel zwischen den europäischen und türkischen Diskursen um den möglichen EU-Beitritt der Türkei. Die Differenzen stellen in der Perspektive postkolonialer Theorien ein ambivalentes und formatives Moment für die Bildung einer europäischen Identität dar: Die Europäer nehmen die Beitrittsverhandlungen zum Anlass, über ihr Selbstverständnis zu reflektieren, wobei diverse Ost-West-Repräsentationen kommuniziert und strukturiert werden. Die muslimischen Migranten in Europa und die Minderheiten in der Türkei fungieren dabei als interne Symptome, die die Unvollständigkeit der europäischen bzw. türkischen Identitäten sichtbar machen.Diese Studie analysiert das dialogische Zusammenspiel zwischen den europäischen und türkischen Diskursen um den möglichen EU-Beitritt der Türkei.

As mulheres sangram : processos de industrialização e urbanização em Aracaju e as relações de trabalho entre 1940–1950
No full textThis article presents a historical analysis of the process of industrialization and urbanization in Aracaju between the 1940s and 1950s, with a focus on the rights of women formally inserted into the labor market during this period. Based on labor lawsuits, the Consolidation of Labor Laws (CLT), and previous legislation, we examine how women claimed their rights. The phrase “women bleed” is used metaphorically to illustrate how they were exploited through low wages, exhausting work hours, and employer strategies that weakened legal protections. Drawing from court cases and records of the Regional Labor Court (TRT) of the 20th Region of Sergipe, we demonstrate that, despite labor protection laws — and later the CLT — employers often circumvented them, forcing workers into costly and unequal legal battles. These challenges disproportionately affected women due to the specific exclusions and rights violations they faced because of their gender.Neste artigo, propomos uma análise histórica do processo de industrialização e urbanização em Aracaju entre os anos de 1940 e 1950, com destaque nos direitos das mulheres inseridas formalmente no mercado de trabalho nesse período. A partir de processos trabalhistas e da Consolidação das Leis do Trabalho (CLT) e leis anteriores, verificamos como as mulheres reivindicavam seus direitos. O termo "as mulheres sangram” aqui é atribuído de forma metáfora e significa que as mulheres eram exploradas com baixos salários, jornadas exaustivas de trabalho e estratégias dos empregadores que diminuía a proteção legal. Com base nos processos judiciais e registro do Tribunal Regional do Trabalho (TRT) da 20ª Região de Sergipe, demonstraremos que, apesar das leis de proteção ao trabalhador e posteriormente a CLT, os empregadores frequentemente a contornavam, tendo que o empregado se submeter a uma batalha custosa e desigual. Fatores que atingiam ainda mais as mulheres dado as especificidades das exclusões e violações de direitos das quais estavam submetidas por serem mulheres.São Cristóvão, S
Climate and anthropogenic change in aquatic environments: A cross ecosystem perspective
No full textThe chapter, "Climate and anthropogenic change in aquatic environments: A cross ecosystem perspective" was written by the listed authors including Jessica L. Clasen (Douglas College Faculty). The Ecological Dissertations in the Aquatic Sciences (Eco-DAS) symposia bring together 35-40 recent PhD recipients for one week in alternate years. Eco-DAS VIII was held in 2008. Eco-DAS is sponsored by the Center for Microbial Oceanography: Research and Education (C-MORE), the University of Hawai`i School of Ocean and Earth Science and Technology (SOEST) and its Department of Oceanography, and the Association for the Sciences of Limnology and Oceanography (ASLO). The Proceedings of Eco-DAS VIII includes nine chapters published in open access.
In an effort to foster collaboration among researchers across diverse ecosystems, a group of early career scientists whose interests span the aquatic sciences, convened at the University of Hawai’i to participate in the 2008 Eco-DAS symposium. During a break out session of the symposium in which participants were charged with discussing how to best approach mitigation of climate and anthropogenic threats to aquatic ecosystems, participants concluded that effective mitigation will depend upon prioritizing threats across ecosystems. These priorities were documented using a thought experiment in which participants defined their ecosystem of expertise, and then ranked the highest-priority threats to them. Results revealed that marine (open ocean, deep sea, coastal oceans, and rocky intertidal) researchers ranked climate-related impacts (i.e., temperature and ocean acidification) as the highest priority threats whereas estuarine, marsh, wetland, stream, and lake/reservoir researchers ranked the direct anthropogenic impacts of land-use change and nutrient inputs (eutrophication) highest. With such a diverse group, it became apparent that working across ecosystems is limited by issues rang- ing from a lack of large-scale, long-term monitoring to provide baseline data, to broader questions of how changes in one ecosystem cascade across interconnected ecosystems. Here we summarize the discussions, offer insight into the rankings for specific ecosystems, and propose ideas of how past, current, and future research can be used to support a cross-ecosystem perspective on climate and anthropogenic change.book chapterPublished
The vulnerability of ecosystem trophic dynamics to anthropogenically induced environmental change: A comparative approach
No full textThe chapter, "The vulnerability of ecosystem trophic dynamics to anthropogenically induced environmental change: A comparative approach" was written by the listed authors including Jessica L. Clasen (Douglas College Faculty).
The Ecological Dissertations in the Aquatic Sciences (Eco-DAS) symposia bring together 35-40 recent PhD recipients for one week in alternate years. Eco-DAS VIII was held in 2008. Eco-DAS is sponsored by the Center for Microbial Oceanography: Research and Education (C-MORE), the University of Hawai`i School of Ocean and Earth Science and Technology (SOEST) and its Department of Oceanography, and the Association for the Sciences of Limnology and Oceanography (ASLO). The Proceedings of Eco-DAS VIII includes nine chapters published in open access.
We employed a comparative approach to review the vulnerability of the trophic interactions within aquatic systems to global threats associated with anthropogenic activities. The goal of this chapter was to identify and characterize mechanisms by which human-mediated environmental threats may modulate trophic dynamics across aquatic ecosystems. Trophic dynamics include some of the most obvious and pervasive factors influencing ecosystems and were used as a metric because of their importance and commonality across all aquatic environments. Our use of trophic dynamics proved to be insightful, illustrating that the flow of energy through aquatic food webs will be (or already has been) altered by invasive species, land-use change, nutrient loading, exposure to ultraviolet radiation, overharvesting, acidification, and increasing global temperatures. The response of trophic dynamics to these threats was often similar across oceans, estuaries, lakes, and rivers. This similarity proved to be interesting given the differences in both the level of concern expressed by scientists and the predicted variability in environment-specific responses. As the trophic interactions of an ecosystem are at the root of its function and structure, examining trophic dynamics could be an informative method for evaluating the response of aquatic environments to global threats. If future analyses validate the use of trophic dynamics as a metric, it is our hope that trophic dynamics can be used by scientists and politicians to mitigate the effects of human actions.book chapterPublished
