Min studie syftar till att, utifrån Werner G. Jeanronds teologiska förståelse av kärlek undersöka den kärlek som kommer till uttryck i Ingmar Bergmans serien Scener ur ett äktenskap. Uppsatsens huvudsakliga frågeställning lyder; Hur framträder kärleksbegreppet i Ingmar Bergmans serie Scener ur ett äktenskap belyst genom Werner G. Jeanronds teologi om kärlek i boken Kärlekens teologi? Utifrån denna analys undersöker uppsatsen slutligen även följande frågeställning; Hur framträder Jeanronds teologi om kärlek i boken Kärlekens teologi belyst genom Bergmans serie Scener ur ett äktenskap?

Denna uppsats har som syfte att undersöka de teologiska aspekterna av människans sexuella begär. Genom en poetisk-filosofisk analys av Alina Reyes erotiska novell Slaktaren och 1300-tals mystikern Julian av Norwichs bok Uppenbarelser av den gudomliga kärleken ämnar uppsatsen belysa relevanta teologiska teman och frågeställningar gällande sexualitetens koppling till teologin och talet om eros som begärets gudomliga ursprung. Studien syftar också till att utforska hur de teman om sexuellt begär som framträder genom denna analys kan anses korrelera med de samtida teologerna Carter Heyward och Ola Sigurdsons syn på sexualiteten. Som ett teoretiskt ramverk används fem hypoteser gällande sexualitet som är hämtade från Mark D. Jordans resonemang i boken The Ethics of Sex. / The purpose of this essay is to examine the theological aspects of human sexual desire. Through a poetic-philosophical analysis of Alina Reye's erotic novel The Butcher and 14th Century Mystic Julian of Norwich's book Revelations of the Divine Love, the essay aims to shed light on relevant theological themes and issues concerning sexuality's connection to theology and the talk of eros as the divine origin of desire. The study also aims to explore how the themes of sexual desire that emerge through this analysis can be considered to correlate with the contemporary theologians Carter Heyward and Ola Sigurdson's views on sexuality. As a theoretical framework, five hypotheses regarding sexuality are used, which are taken from Mark D. Jordan's reasoning in the book The Ethics of Sex.

Mémoire en recherche / Cette étude s’intéresse à l‘impact de l’adaptation cinématographique et à l’évolution du récit écrit par Marguerite Yourcenar, Le Coup de grâce, publié en mai 1939, au sujet de trois jeunes êtres qui se ressemblent et qui s’aiment dans un triangle relationnel compliqué dans le cadre de la guerre civile balte au lendemain de la fin de la Première Guerre mondiale. La présente étude se centre sur l’évolution des dimensions de la représentation du système des personnages, de l’éros, des genres (la masculinité dont les frontières évoluent dans le temps et l’espace) et de la guerre (une force thanatique) lors de l’adaptation cinématographique faite par Volker Schlöndorff en 1976, bref à l’impact du nouveau média sur l’histoire originale et les aspects initiaux imaginés par Marguerite Yourcenar en 1938 dans son roman Le Coup de grâce, où les mythes gréco-romains étaient une constante dans ses motifs d’inspiration pendant cette période des années 1930, où ces écrits réfutaient les pressions rigoristes qui perduraient dans cette décennie. Éric, le narrateur homodiégétique du roman était à la recherche d’une certaine liberté sexuelle et il faisait son récit un peu sur le ton de la confession intimiste, tel un journal de guerre. Rémy Poignault considère Le Coup de grâce comme une réécriture moderne, un palimpseste donc de « Patrocle ou le destin » de Feux avec des personnages appartenant à l’époque moderne. Le passage au film en 1976 déplace l’accent mis sur Éric dans le roman vers la dualité entre lui et Sophie dans le récit filmé, où les personnages perdent de leur profondeur, réduisant Éric à un être insensible, et ce, en limitant les scènes de camaraderie militaire avec Conrad. L’absence de prologue dans le film ne permet pas non plus d’évoquer les souvenirs heureux vécus à Kratovicé. Dans le film, la grande histoire prend le pas sur la petite histoire contrairement à ce qu’entendait Marguerite Yourcenar qui mettait l’accent sur le drame humain dans la préface de son roman. Le film priorise plutôt l’affirmation 5 d’une femme par rapport à son milieu dans la lignée d’autres films de Volker Schlöndorff comme L’honneur perdu de Katharina Blum. Le film est en somme un film féministe à l’image de Margarethe von Trotta qui était un des chantres du féminisme dans les années 1970 et qui collabora au scénario dudit film. Il s’agit donc d’une adaptation libre avec certains retranchements ou modifications par rapport à l’oeuvre originale. En enlevant de nombreuses scènes de camaraderie militaire entre les deux principaux personnages, le mythe grec ancien d’Achille et Patrocle présent en filigrane dans le roman est évacué dans le film. Tant le roman que le film se sont inspirés d’un certain académisme qui engendra une atmosphère limitant les émotions des personnages. / That research concerns the analysis of the evolution of the written narrative of Marguerite Yourcenar about three young characters who look like each other and who loves each other in relational triangle within the background context of the Baltic Civil War just after The First World War of 1914-18 and in its adaptation in film by Volker Schlöndorff in 1976. This study concentrates about representation of character’s system, dynamic of eros, represensation of gender for instance the masculinity and the war during the adaptation for the cinema by Volker Schlöndorff. Briefly, to the impact of the new media on the original themes which were developed in the original novel of Marguerite Yourcenar in 1939, Le Coup de grâce. Our study presents itself in a chronological order for making some conclusions about representations of the themes of desire and death, gender and war in the time from the story written 1939 and the film in 1976 We can conclude after analysis of both media for the narrative that Mythical figures as Thanatos and Eros present in this novel received a different treatment in the film adaptation where the emphasis moved to the dualistic relation between Eric and the women Sophie. The movie has become a feministic which puts emphasis on a woman against her social middle and diminish the impact of the mythical military friendship related to the mythic military myth of Achille and Patrocle which was underlined but present in the novel with the death of one main characters on the battlefied of the story. In taking off most of the scenes of military friendship between the two men charaters, the mythical part of the novel, is evacuated. The film adaptation is a free adaptation according to the classification of adaptation film of Esther Pelletier with retranchments and changes from the novel.

This dissertation is a collection of poems preceded by a critical preface. The preface considers emotional immediacy—or the idea of enacting in readers an emotional drama that appears genuine and simultaneous with the speaker's experience—and furthermore argues against the common criticism that accessibility means simplicity, ultimately reifying the importance of accessibility in contemporary poetry. The preface is divided into an introduction and three sections, each of which explores a different technique for creating immediacy, exemplified by Robert Lowell’s "Waking in the Blue,” Sylvia Plath's "Lady Lazarus,” and Louise Gluck's "Eros." The first section examines "Waking in the Blue,” and the poem's systematic inflation and deflation of persona as a means of revealing complexity a ambiguity. The second section engages in a close reading of "Lady Lazarus,” arguing that the poem's initially deliberately false erodes into sincerity, creating immediacy. The third section considers the continued importance of persona beyond confessionalism, and argues that in "Eros," it is the apparent lack of drama, and the focus on the cognitive process, that facilitates emotional immediacy.

Mit der Behauptung, dass seine eigene Philosophie als »umgedrehter Platonismus« verstanden werden soll, stellt Nietzsche seine Beziehung zum platonischen System dar. Dieses Forschungsprojekt sucht nach einer neuen Variation dieser Darstellung, um die philosophischen Analogien beider Autoren aufzuspüren. Das erste Kapitel beschäftigt sich mit einer Erläuterung des Begriffes „umgedrehter Platonismus“, womit die Differenz zwischen diesen beiden Systemen definiert wird. Diese Diskrepanz ist spürbar in vier verschiedene Bereichen: metaphysisch, axiologisch, gnoseologisch und ästhetisch. Das zweite Kapitel behandelt die Rolle des Apollinischen und des Dionysischen in der nietzscheschen Theorie. Die beiden Konzepte werden mit dem des platonischen Eros verglichen, da diese es dem Menschen ermöglichen, die sinnliche Welt zu verlassen und eine Ur-Realität kennenzulernen. Das dritte Kapitel analysiert die Verurteilung der Kunst in Platon’s „Staat“. Der griechische Philosoph strebt die wahre Kenntnis an und verbindet seine ästhetischen Überlegungen mit der Idee der Wahrheit. Nietzsche bearbeitet diese Verbindung zwischen Ästhetik und Erkenntnistheorie unter dem Begriff »amor fati«. Das vierte Kapitel ist der Physiologie der Liebe gewidmet. Nietzsche verwandelt der Erkenntnisprozess in eine leidenschaftliche Liebe. Die Erkenntnis nimmt die Form einer Passion an und kristallisiert sich allmählich und nach einem langen Prozess mit Höhen und Tiefen in »amor fati«. »Amor fati« schafft eine Ästhetisierung der Erkenntnis und Epistemologiesierung der Ästhetik. Somit liegt Nietzsches Erkenntnistheorie parallel zu jener Platons. / By claiming that his philosophy should be understood as “inverted Platonism” Nietzsche defined his relationship to the Platonic system. This research project aims to articulate a new understanding of this relationship by analyzing philosophical similarities between the two authors'' respective philosophies. The first chapter is dedicated to the explanation of the term “inverted Platonism” and articulates the differences between Plato''s and Nietzsche''s systems. These discrepancies are manifested in four main areas: the metaphysical, the axiological, the gnosiological and the aesthetic. The second chapter deals with the roles of the Apollonian and the Dionysian in Nietzschean theory. Both concepts are compared with the Platonic Eros, as they invite man to abandon the sensual world and instead to commune with the very origin of reality. The third chapter analyzes Plato´s denunciation of art in “The Republic”. The Greek philosopher seeks true knowledge and connects his aesthetic concerns with the idea of Truth. Nietzsche refers to the cynosure between aesthetics and cognitive theory as “amor fati”. The fourth chapter is dedicated to the physiology of love. Nietzsche transforms the cognitive process into a passionate love. Cognition assumes the shape of passion, slowly crystallizing over time, with many twists and turns, into “amor fati”. “Amor fati” aestheticizes cognition and epistemologizes aesthetics. Therefore Nietzsche''s cognitive theory is actually equivalent to that of Plato.

Extra-marital affairs are the main reason for divorce in western society. Pastoral therapists usually operate within a modernistic theology and use their 'expert' knowledge of theological ethics to confront the unfaithful spouse - a pastoral therapeutic approach that neither delivers the desired results, nor honours the client's expertise and freedom. This study endeavoured to socially construct pastoral therapy using the principles of postmodernistic social construction discourse with couples/spouses where one spouse is or was engaged in an extramarital affair. The relation between a modernistic epistemology and a postmodernistic epistemology, and how this relation affects theology, practical theology and pastoral therapy were explored. The propium of pastoral therapy in a postmodemistic paradigm and the implications of a narrative approach in pastoral therapy for theological ethics were reflected upon. A narrative description of extra-marital affairs was constructed and some of the cultural discourses which co-constitute extra-marital affairs were discussed. The pastoral therapist and clients were simultaneously in conversation with ethical discourses and relational, personal and emotional discourses, thus co-constructing new alternatives and possibilities. During these multiple reflexive conversations, some of the cultural discourses (eros; self-fulfilment; extra-marital sex and hedonism) which co-constitute extra-marital affairs were deconstructed. In the light of the usual limitations of the life-span of an extra-marital affair, the pastoral therapist and faithful spouses socially constructed alternatives and possibilities for their lives to enable them to outstay the extra-marital affair of the unfaithful spouse. Multiple reflexive conversations with (un)faithful spouses co-constructed, with relational and ethical discourses, a narrative approach in pastoral therapy. The use of externalisation and ritualisation in a narrative approach in pastoral therapy concerning extra-marital affairs was explored. A sense of guilt and secrets were also themes in multiple reflexive conversations with unfaithful spouses. This prompted reflection on the use of Scripture in a narrative approach in pastoral therapy. The relation between the biological-psychological aspects of extra-marital affairs and narrative therapy are also briefly explored. / Philosophy, Practical & Systematic Theology / D. Th.

Cette étude traite des représentations littéraires du « démon de la fornication » et des notions avoisinantes du tabou et de la transgression dans la société tardo-antique de l’Orient chrétien à travers la lecture des Vies de saints. Elle focalise sur les « Vies de saintes prostituées » et celles « de saintes adultères », qui concrétisent les perceptions de l’homme tardo-antique autour de la question de la transgression des tabous sexuels. Mais à côté de la représentation littéraire de la transgression réelle (d’ordre principalement sexuelle) de normes sociales, nous serons étonnés de trouver d’autres formes de transgression, tantôt imaginaire tantôt réelle. Pour cette raison nous avons examiné d’autres cas « marginaux » de saints, dont les Vies nous fournissent des indices précieux sur toute la gamme de normes sociales et de prescriptions taboues de la société tardo-antique : la fuite du mariage, le refus du travail, l’homosexualité, la contestation du pouvoir (paternel et politique), la mendicité, le vagabondage, la folie et le rire n’étant que les plus importants. Pourtant, la seule énumération de ces sujets pose un autre problème éminemment plus important que la représentation littéraire, celui de la place des marginaux dans cette société. Quelle était la place, alors, de tous ceux qui étaient considérés comme des « rejetés » sociaux dans la société de l’Antiquité tardive, quelle était la place des prostituées, des adultères, des homosexuels, des fous, des clochards, des chômeurs, des vagabonds et quelles étaient les attitudes vis-à-vis d’eux et quelles répercussions sociales et psychologiques affrontaient-ils ? En essayant de répondre, nous avons essayé de mettre en avant l’hypothèse de l’existence d’une catégorie particulière de Vies de saints qui traiterait toutes ces questions taboues : les « Vies de saints populaires » dont les principales caractéristiques nous avons essayé d’établir et d’interpréter dans une synthèse historique qui conclue cette étude. / This study treats the literary representations of the “demon of fornication” and the adjacent notions of taboo and transgression in the late-antique society of Christian East through a close reading of the Lives of Saints. It focuses on the “Lives of Holy Harlots” and those of “Holy Adulteresses”, which materialize the late-antique man’s perceptions about the question of the transgression of the sexual taboos. But just along with the literary representations of social norms’ real transgression, mostly sexual, we can also find other forms of transgression, either real or imaginary. For this reason we have examined other cases of “border-line” saints, whose Lives provide us with precious indications about the whole range of social norms and the taboo limitations of the late-antique society: the denial of marriage and work, the homosexuality, the contesting of the paternal and political power, the begging, the wandering, the madness and the laughter, only being the most important. However, the simple enumeration of such subjects evokes the question of the position of the outcasts in this society. Which was the place of all those who were considered as social “rejections” in the late-antique society, which was the place of prostitutes, of adulteresses, of homosexuals, of foolish people, of the wandering or begging workless people, and which were the attitudes towards them or the social and psychological repercussions that they were obliged to confront? Upon trying to answer to these questions, we’ve stumbled upon the existence of a distinct category of Lives of Saints which treats all those taboo subjects: the “Lives of popular Saints” (or the “Popular Lives of Saints”), whose main characteristics we have tried to establish and to interpret in an historical synthesis that concludes this study.

As plantas, assim como outros organismos, possuem a capacidade de se defenderem contra ataque de patógenos. Uma das respostas desencadeadas pelo reconhecimento do patógeno pelas células vegetais é a reação de hipersensibilidade (RH), que envolve a morte imediata das células do sítio primário de infecção, oferecendo resistência ao crescimento do patógeno. Muitas evidências sugerem a participação da mitocôndria neste processo de morte celular programa. O nim (Azadirachta indica) é conhecido devido as suas propriedades medicinais e inseticidas, sendo que os estudos sobre a ação inseticida dessa planta restringem-se a análise de seus mecanismos de ação sobre insetos e também de seus efeitos sobre trabalhadores rurais que fazem uso de produtos a base de nim. Entretanto não há na literatura pesquisada, trabalhos de seus impactos sobre o sistema vegetal. A partir dos resultados previamente obtidos em nosso laboratório e com as análises dos dados da literatura, consideramos de grande importância dar continuidade a esse estudo do efeito do nim como elicitor, avaliando quais mecanismos que levam ao fenômeno de resistência vegetal. O extrato de nim (EB) foi preparado a partir das sementes, sendo caracterizado bioquimicamente pela quantificação de compostos fenólicos, açúcares e proteínas. A atividade antioxidante foi avaliada sendo possível observar que o extrato das sementes de nim possui forte atividade antioxidante de maneira dose-dependente com IC50 de 14,85 mg/mL. Para os ensaios biológicos foi utilizado EB nas concentrações de 0,1 a 5 mg/mL isolado ou em associação com AS a 1 µmol/L ou 1 mmol/L. Para determinação da morte celular foi observado o efeito do EB nas concentrações de 5 e 0,1 mg/mL isolado ou em associação com AS 1 µmol/L nos tempos de 0 a 8 horas. Diante dos resultados foi observado que o EB na concentração de 0,1 mg/mL isolado ou em associação com AS 1 µmol/L foi capaz de causar morte celular em células de Rubus fruticosus de forma mais significativa do que o EB isolado ou em associação com AS na concentração de 5 mg/mL. No tempo de 8 horas, foi observado uma porcentagem de morte celular de 64 % para células elicitadas com EB 0,1 mg/mL isolado e 71 % para células elicitadas com EB 0,1 mg/mL em associação com AS. A diminuição da produção de EROs e da produção de AS endógeno bem como o aumento da produção de compostos fenólicos foi observado em células intactas elicitadas com EB isolado. No entanto quando a células foram elicitadas com EB em associação com AS observamos uma diminuição da produção de compostos fenólicos com o aumento da produção de AS endógeno. Em mitocôndrias isoladas foi avaliado o consumo de oxigênio, o potencial de membrana e a produção de EROs com o EB isolado e sua associação com AS 1 mmol/L. Foi observado que o EB isolado ou em associação com AS foi capaz de diminuir a velocidade de consumo de oxigênio pela cadeia respiratória sendo este efeito mais acentuado quando o nim foi administrado juntamente com AS, onde a porcentagem de inibição da velocidade de consumo de oxigênio pela cadeia respiratória na presença de EB em associação com AS foi de 79 % no estado 3 da respiração e 62 % no estado 4. Sobre o potencial de membrana observamos que o EB isolado ou em associação com AS foi capaz de diminuir o potencial de membrana, porém de forma pouco significativa. Para a produção de EROs observamos que o EB isolado foi capaz de diminuir a produção de EROs em mitocôndrias isoladas em cerca de 55 a 20 % na presença de antimicina A e 39 a 10 % na presença de rotenona, porém quando o EB foi administrado juntamente com AS observamos uma diminuição da produção de EROs somente para o EB nas concentrações de 0,5; 1 e 5 mg/mL. Com os resultados apresentados neste trabalho e os resultados obtidos anteriormente em nosso laboratório é possível sugerir que o extrato das sementes de nim possui um efeito protetor sobre células de Rubus fruticosus. / Plants, like other organisms, have the capacity to defend themselves against attack by pathogens. One of the responses triggered by pathogen recognition by plant cells is the hypersensitive response (HR), which involves the immediate death of cells in the primary site of infection, providing resistance to the pathogen growth. In this regard, it has been well established that mitochondria are involved in cell death. The neem tree (Azadirachta indica) is known due to its medicinal and insecticidal properties; studies on the insecticidal action of this plant had been restricted to the analysis of their action mechanisms on insects and their effects on rural workers who use neem-based products. However, its impact on plant systems has not been addressed. Considering previous results from our laboratory and literature data we assessed the effects of neem as elicitor, particularly the mechanisms leading to the phenomenon of plant resistance. The neem extract (EB) was prepared from the seeds, characterized biochemically by quantification of phenolic compounds, sugars and proteins. The extract showed strong dose-dependent antioxidant activity (IC50 of 14.85 mg/mL). EB concentrations of 0.1-5 mg/mL, alone or in association with 1 mol/L or 1 mmol/L SA (salicylic acid), were used for the biological assays. For cell death assays, EB was employed in concentrations of 0.1 and 5.0 mg/mL, alone or in association with 1 mol/L SA, during 0-8 hours. EB (0.1 mg/mL), alone or in association with 1 mol/L SA, induced Rubus fruticosus cell death more efficiently than EB alone or in association with 5 mg/mL SA. After 8 hours, a 64% of death of cells elicited with 0.1 mg/mL EB and 71% of death of cells elicited with 0.1 mg/mL EB in association with SA, was observed. Decrease in ROS generation and production of endogenous SA, as well as increased production of phenolic compounds, was observed in intact cells elicited with EB alone. However, when cells were elicited with EB in association with SA, a decreased production of phenolic compounds and an increased production of endogenous SA, was observed. In isolated mitochondria, it was measured oxygen consumption, membrane potential and ROS production for EB alone or in association with 1 mmol/L SA. In either conditions, EB decreased oxygen consumption by the respiratory chain, an effect more pronounced in association with SA: ~79 % inhibition for state 3 and ~ 62 % for state 4 respiration. Also, either neem alone or in association with SA decreased mitochondrial membrane potential, as well as ROS generation to an extent of 55-20% in the presence of antimycin A and 39-10% in the presence of rotenone; in association with SA, EB decreased ROS at 5, 1 and 0.5 mg/mL. Together with our previous study, these results suggest that neem seeds extract has a protective effect on Rubus fruticosus cells by scavenging, via phenolic compounds, reactive oxygen species generated by SA, thereby decreasing its action as cell death inducer.

Como os outros organismos, as plantas têm a habilidade de se defenderem através do reconhecimento de patógenos (resposta de hipersensibilidade - RH), causando a morte imediata das células no sítio primário da infecção, desta maneira oferecendo resistência ao seu crescimento. A RH é caracterizada pela necrose dos tecidos neste local, através de muitos sinais ainda não completamente elucidados, como a formação de radicais livres, incluindo o peróxido de hidrogênio (H2O2), e o reforço da parede celular. O objetivo deste estudo foi estabelecer a relação entre esses sinais em cultura de células de amora-preta (Rubus fruticosus). As condições experimentais para a análise da parede celular, das espécies reativas de oxigênio (EROs) e do H2O2 foram padronizadas. O polissacarídeo ácido (ramnoglucuronogalactana, F-I), o ácido salicílico (AS), e o metil jasmonato (MeJA), bem estabelecidos efetores da resposta da defesa, foram usados como elicitores. A produção das EROs e do H2O2 foram ativadas por F-I e pelo AS, seguidos da liberação de fragmentos de dissacarídeos da parede celular, aparentemente devido a sua degradação. Por outro lado, uma produção pequena de EROs e de H2O2 foram observadas na presença de MeJA, assim como um aumento de fragmentos de massa molecular mais elevada, que podem funcionar como sinais para o reforço da parede celular, indução de enzimas e para a produção de outra moléculas de defesa. Quando da elicitação, concomitante, com dois elicitores, AS + MeJA, houve a inibição da produção de EROs causada pelo MeJA e foi mantida a liberação de compostos extracelulares de massa molecular mais elevada. / Like the other organisms, plants have the ability to self-defend through recognition of pathogens (hypersensitive response - HR), causing immediate cell death at the primary infection site, thus offering resistance to their grown. The HR is characterized by necrosis of tissues in this site via many signals still not completely elucidated, like formation of free radicals including H2O2 and reinforcement of cell wall. The aim of this study was to establish the relationship between these signals in blackberry-black cell culture (Rubus fruticosus). The experimental conditions for analysis of cell wall, reactive oxygen species (ROS) and H2O2, were established. Acid polysaccharide (rhamnoglucuronogalactan, F-I), salicylic acid (SA), and methyl jasmonate (MeJA), well established effectors of the defense response, were used as elicitors. ROS and H2O2 production was activated by F-I and SA, followed by release of fragments like disaccharides from the cell wall, apparently due to its degradation. By contrast, a small production of ROS and H2O2 was observed in presence of MeJA, as well as an increase of high molecular weight fragments, that may function as signals for reinforcement of cell wall, enzyme induction and production of others defense molecules. Together, the two elicitors SA and MeJA inhibited the ROS production, caused by MeJA, while sustaining release of the extra cellular compounds of high molecular weight.

A produção intracelular e ativação do oxigênio molecular em suas espécies reativas é uma constante ameaça aos organismos fotossintéticos, uma vez que os cloroplastos, juntamente com as mitocôndrias, são compartimentos celulares altamente susceptíveis ao estresse oxidativo. Em condições normais, a geração das EROs nestas organelas é lenta e controlada, embora possa ser exacerbada pela exposição a agentes poluentes, tais como metais e poluentes orgânicos. A contaminação por metais é uma importante fonte de estresse oxidativo em sistemas biológicos, a resistência dos organismos fotossintéticos ao estresse metálico deve-se a adaptações bioquímicas que previnam o desequilíbrio oxidativo. Nesta dissertação investigamos os efeitos dos íons Cd2+ na microalga Minutocelluspolymorphus. A microalga mostrou-se sensível ao Cd2+ devido a um aumento significativo na mortalidade celular quando sob exposição. Através de várias exposições, o valor da IC50 do Cd2+ para a microalga foi de 0,14 mmol.L-1. As respostas dos principais sistemas antioxidantes enzimáticos e não enzimáticos também foram avaliadas. Após 48 horas de exposição a Cd2+, as células apresentaram aumentos de atividade das enzimas SOD, CAT e GST em 3,5, 6,2 e 2 vezes respectivamente. Esta exposição também provocou a redução da atividade da enzima GR em 28 %. Neste sentido, os níveis de GSH também foram alterados, apresentando uma redução de 60 % quando sob exposição ao metal. Contudo, não houve alteração na atividade da enzima GPx. A partir das informações obtidas neste trabalho, conclui-se que Cd2+ é tóxico à M. polymorphus, sendo forte indutor do estresse oxidativo às suas estruturas celulares da microalga, causando alteração em seu perfil antioxidante, podendo ser utilizadas como biomarcadores para exposição de Cd2+ em condições controladas. O presente trabalho contribui, portanto, para uma maior elucidação dos componentes bioquímicos e moleculares de processos adaptativos em microalgas marinhas. / The intracellular production and activation of molecular oxygen to reactive species is a constantly threat to photosynthetic organisms once chloroplasts and mitochondria are cellular compartments highly liable to oxidative stress. In normal conditions the generation of ROS on this organelles is slow and controlled although can be exacerbated by the exposure to pollutants agents as metals and organic pollutants. Contamination by metals is an important source of oxidative stress in biological systems, the resistance of the photosynthetic organisms to this stress due to biochemical adaptations that prevent oxidative imbalance. In this work, we investigated the effects of Cd2+ ions on microalgae Minutocellus polymorphus. The microalge showed sensible to Cd2+ effects due to significant increase on cellular death when exposed. Through several exposures, the value of IC50 was determined as 0.14 mmol.L-1. The responses of major antioxidant systems both enzymatic and non-enzymatic were also evaluated. After 48 hours of exposition to Cd2+, the cells showed increases of antioxidant enzymes SOD, CAT and GST in 3.5, 6.2 and 2 times respectively. This exposure also significantly decreased enzyme GR activity by 28 %. In this way, GSH levels were also changed, with a reduction of 60% when under exposure to metal. However, there was no change in the activity of GPx enzyme. From the information obtained in this work, we conclude that Cd2+ is toxic to M. polymorphus, being strong inducer of oxidative stress to their cellular structures, causing the consequent change in antioxidant profile that can be used as biomarkers that can be used as biomarkers of Cd2+ exposure on controlled conditions. This study therefore contributes to a further elucidation of the biochemical and molecular components of adaptive processes in marine microalgae.
