Die beiden untersuchten Texte, Sophokles' Antigone und Gorgias von Platon, wurden in dieser Arbeit als Momentaufnahmen für verschiedene Formen, Gerechtigkeit im 5. und 4. Jahrhundert v. u. Z. zu denken, interpretiert, um so einen möglichst authentischen Eindruck von Gerechtigkeit zu jener Zeit zu erhalten. Die Methode der Begriffsgeschichte hatte vorgegeben, dass beide Texte zunächst unabhängig von einander untersucht und die Ergebnisse anschließend zusammengeführt werden sollten. In der Analyse fächerten die Quellen zunächst jeweils in sich ein breites Spektrum unterschiedlicher Auffassungen von Gerechtigkeit auf, die Verbindung beider Betrachtungen machte darüber hinaus Strukturen von Ähnlichkeit und Differenz sichtbar. Daraus ergab sich ein Schema, das die sehr unterschiedlichen Aspekte als verschiedene Eckpunkte eines Prozesses verstehbar machte, der vor dem Hintergrund des in der Einleitung gegebenen historischen Kontextes interpretiert werden konnte. In der Einführung wurde bald deutlich, dass die verschiedenen Vorstellungen von Gerechtigkeit immer auch die Themenkomplexe von Ethik und Moral, von Wahrheit und Wirklichkeit mit einschließen mussten. Mit Victor Ehrenberg ließ sich die Überlegung zu Gerechtigkeit in dem größeren Kontext des Bedeutungswandels von Themis über Dike zu Nomos verstehen. Diese erste Begriffsgeschichte des Konzepts „Gerechtigkeit“ bereitete die Analyse von Gerechtigkeit in den Quellen vor. Das Untersuchungsfeld konnte damit für den Zeitraum der Quellen auf den Begriff des „Nomos“ eingrenzt werden. Dass das besondere Spannungsverhältnis von Nomos und Physis bis in die unterschiedlichen in den Quellen vertretenen Positionen der Gerechtigkeit hineinwirken musste, zeigte sich dann später in der Quellenanalyse. ...
In the past, the genetically diabetic-obese diabetes/diabetes (db/db) and obese/obese (ob/ob) mouse strains were used to investigate mechanisms of diabetes-impaired wound healing. Here we determined patterns of skin repair in genetically normal C57Bl/6J mice that were fed using a high fat diet (HFD) to induce a diabetes-obesity syndrome. Wound closure was markedly delayed in HFD-fed mice compared to mice which had received a standard chow diet (CD). Impaired wound tissue of HFD mice showed a marked prolongation of wound inflammation. Expression of vascular endothelial growth factor (VEGF) was delayed and associated with the disturbed formation of wound margin epithelia and an impaired angiogenesis in the reduced granulation tissue. Normal wound contraction was retarded and disordered. Wound disorders in obese C57Bl/6J mice were paralleled by a prominent degradation of the inhibitor of NFκB (IκB-α) in the absence of an Akt activation. By contrast to impaired wound conditions in ob/ob mice, late wounds of HFD mice did not develop a chronic inflammatory state and were epithelialized after 11 days of repair. Thus, only genetically obese and diabetic ob/ob mice finally developed chronic wounds and therefore represent a better suited experimental model to investigate diabetes-induced wound healing disorders.
Cells can respond to stress in various ways ranging from the activation of survival pathways to the initiation of cell death that eventually eliminates damaged cells. Whether cells mount a protective or destructive stress response depends to a large extent on the nature and duration of the stress as well as the cell type. Also, there is often the interplay between these responses that ultimately determines the fate of the stressed cell. The mechanism by which a cell dies (i.e., apoptosis, necrosis, pyroptosis, or autophagic cell death) depends on various exogenous factors as well as the cell's ability to handle the stress to which it is exposed. The implications of cellular stress responses to human physiology and diseases are manifold and will be discussed in this review in the context of some major world health issues such as diabetes, Parkinson's disease, myocardial infarction, and cancer.
One of the hallmarks of human cancers is the intrinsic or acquired resistance to apoptosis. Evasion of apoptosis can be part of a cellular stress response to ensure the cell's survival upon exposure to stressful stimuli. Apoptosis resistance may contribute to carcinogenesis, tumor progression, and also treatment resistance, since most current anticancer therapies including chemotherapy as well as radio- and immunotherapies primarily act by activating cell death pathways including apoptosis in cancer cells. Hence, a better understanding of the molecular mechanisms regarding how cellular stress stimuli trigger antiapoptotic mechanisms and how this contributes to tumor resistance to apoptotic cell death is expected to provide the basis for a rational approach to overcome apoptosis resistance mechanisms in cancers.
Cell stress and cell death
(2010)
Editorial: This special issue on Cell Stress and Cell Death is aimed at bringing together recent developments in the fields of cellular stress and cell death and, in particular, the interplay between cell stress responses and cell death. The special issue opens with a review by S. Fulda et al. which provides an overview of how cells can respond to stress in a variety of ways ranging from the activation of survival pathways to the initiation of cell death that eventually eliminates damaged cells. Whether cells mount a protective response or succumb to death depends to a large extent on the nature and duration of the stress as well as the cell type. For example, milder stresses can lead to protection through activation of the heat shock response or the unfolded protein response (UPR). This review also describes several types of cell death (e.g., apoptosis, necrosis, pyroptosis, or autophagic cell death) and the mechanism by which a cell dies often depends on various exogenous factors as well as the cell’s ability to handle the stress to which it is exposed. The implications of cellular stress responses for human physiology and disease are multifold and are discussed in this review in the context of some major world health issues such as diabetes, Parkinson’s disease, myocardial infarction, and cancer. ...
Generationen der Liebe
(2010)
Rezension zu: Holger Herma: Liebe und Authentizität. Generationswandel in Paarbeziehungen. Wiesbaden: VS Verlag für Sozialwissenschaften 2009. 286 Seiten, ISBN 978-3-531-16552-3, € 34,90
Abstract: Holger Herma untersucht den Wandel der gesellschaftlichen Liebenssemantik in der westdeutschen Nachkriegsgeschichte. Dabei ist sein besonderes Anliegen, den Einfluss generationsspezifischer Erfahrungsräume auf die Vorstellungen von Liebe und Partnerschaft empirisch nachzuvollziehen. In der qualitativen Interviewstudie steht das bisweilen spannungsvolle Verhältnis von Liebessemantik und Lebenspraxis, aber auch das Wechselspiel mit anderen gesellschaftlichen Diskursen und Transformationsprozessen, etwa im Geschlechterverhältnis im Mittelpunkt.
European pea crabs - taxonomy, morphology, and host-ecology (Crustacea: Brachyura: Pinnotheridae)
(2010)
Pinnotherids are small crabs symbiotic to a variety of invertebrates. The European species infest bivalves and sea squirts. Their way of life is parasitic and poses a threat to commercially exploited bivalves. While juveniles of both sexes still look very similar - being agile swimmers and partially free living - a metamorphosis takes place in the female after mating and results in a conspicuous sexual dimorphism. Thereafter, the female settles in its host definitely and is morphologically strongly adapted to the parasitic life phase. A very high reproductive output was demonstrated among several pea crab species infesting bivalves. Despite from that, hardly any information is present in the literature on the pinnotherids’ reproductive biology and the underlying morphology.
Due to their cryptic way of life, the sexual dimorphism, and the different morphotypes of the female, the taxonomy of the Pinnotheridae is a serious challenge. Two widely accepted species are recognized on European coasts: Pinnotheres pisum and Nepinnotheres pinnotheres. Pinnotheres pectunculi was so far only known from the bivalve Glycymeris glycymeris in its type locality Roscoff (France), while Pinnotheres ascidicola and Pinnotheres marioni were described as living exclusively in ascidians without careful comparison with the previously described species. In order to produce standardized comparative descriptions, pea crabs were collected and studied from different hosts and localities in the Northeast Atlantic and in the Mediterranean. Nepinnotheres pinnotheres and Pinnotheres pisum were redescribed with consideration to characters of female and male. According to our morphological analysis, Pinnotheres ascidicola and Pinnotheres marioni are junior synonyms of Nepinnotheres pinnotheres, whereas the status of Pinnotheres pectunculi as a valid species was ascertained. Important characters are the mouthparts, the male gonopods, and especially chelipeds that showed consistent characteristics among different crab stages of both sexes.
Based on our sampling, we estimated the host-range of the European species. Nepinnotheres pinnotheres lives in ascidians and in the pen shell Pinna nobilis. Pinnotheres pisum infests numerous bivalve species - Pinna nobilis included. For Pinnotheres pectunculi novel host records are presented, all from the bivalve family Veneridae. Furthermore, feeding of the Pinnotheres-species was observed. They use a setae comb ventrally on the claw to brush mucus (and the accumulated food particles) from the bivalve gills. Feeding strategies and host-ecology will be thoroughly discussed in consideration to other Pinnotheridae.
We investigated the reproductive systems of European pinnotherids by histological methods, scanning and transmission electron microscopy, and confocal laser scanning microscopy.
The Eubrachyura have internal fertilization: paired vaginas enlarge into storage structures, the spermathecae, which are connected to the ovaries by oviducts. Sperm is stored until the oocytes are mature and transported into the spermathecae, where fertilization takes place. In the investigated pinnotherids, the vagina is of the ‘concave pattern’. Musculature is attached alongside flexible parts of the vagina-wall to control the dimension of its lumen. The genital opening is closed by a muscular mobile operculum.
The spermatheca can be divided into two distinct regions by function and morphology. The ventral part includes the connection with vagina and oviduct and is regarded as the zone where fertilization takes place. It is lined with cuticle except where the oviduct enters the spermatheca by the ‘holocrine transfer tissue’. At ovulation, the oocytes have to pass through this multi-layered glandular epithelium, which has a holocrine mode secretion. The dorsal part of the spermatheca is lined by a highly secretory apocrine glandular epithelium, which was to date only found in fiddler crabs of the genus Uca.
The male internal reproductive system consists of paired testes and corresponding vasa deferentia. The sperm morphology of pinnotherids conforms to other thoracotremes, with slight differences between Nepinnotheres pinnotheres and Pinnotheres pisum. Spermatozoa become enveloped into spermatophores in the secretory proximal vas deferens. The medial vas deferens is strongly enlarged and stores spermatophores embedded in seminal plasma. The distal vas deferens holds tubular appendices, which extend into the ventral cephalothorax and slightly into the pleon. These appendices produce and store vast quantities of seminal plasma. The copulatory system of the Brachyura is formed by paired penes and two pairs of gonopods, which function in sperm transfer. In pinnotherids, the long first gonopods transfers the sperm mass to the female. It holds the ejaculatory canal inside, which opens proximally and distally. The second gonopod is solid, short and conical. During copulation, the penis and the second gonopod are inserted into the base of the tubular first gonopod. The second gonopod functions in the transport of the sperm mass inside the ejaculatory canal towards its distal opening. The specific shape of the second gonopod is strongly adapted for a sealing of the tubular first gonopod with longitudinal cuticle foldings that interlock inside the first gonopod. The presented results are discussed concerning their function in reproduction and in respect of the systematic account.
The role of secretion in sperm transfer, storage and fertilization among the Brachyura is still under debate. It is notable that structure and function of secretion are more complex in pinnotherids and probably more efficient than in other brachyuran crabs, which will be discussed, in view of the parasitic way of life and the high fecundity of pinnotherids.
An information system is more than just the information technology; it is the system that emerges from the complex interactions and relationships between the information technology and the organization. However, what impact information technology has on an organization and how organizational structures and organizational change influence information technology remains an open question. We propose a theory to explain how communication structures emerge and adapt to environmental changes. We operationalize the interplay of information technology and organization as language communities whose members use and develop domain-specific languages for communication. Our theory is anchored in the philosophy of language. In developing it as an emergent perspective, we argue that information systems are self-organizing and that control of this ability is disseminated throughout the system itself, to the members of the language community. Information technology influences the dynamics of this adaptation process as a fundamental constraint leading to perturbations for the information system. We demonstrate how this view is separated from the entanglement in practice perspective and show that this understanding has far-reaching consequences for developing, managing, and examining information systems.
Theory building is not only underdeveloped in IT services management research, but in
general in IS. Given the paradigm shift that comes from the development away from a
networked economy towards a network economy, the lack of spending enough attention to
theorizing in IS becomes even more obvious. In the light of other "megatrends" in IS
research, such as the increasing professionalization and use of statistical methods and the
exploitation of extremely large sets of data (often harvested from social media sites), we
might lose interest in theorizing in the presence of the tremendous amount of available
empirical data. In this position paper, the author advocates that services science researchers
should focus on rigor and relevance in their research approaches.
Um olhar rápido sobre os títulos constantes da sua biblioteca particular torna claro que Pessoa lia os autores alemães em traduções inglesas e francesas. Contudo, um escrutínio mais atento da sua biblioteca e dos seus apontamentos revela que o acompanharam ao longo da sua vida não só uma vontade mas também algumas tentativas concretas de enveredar pelo estudo da língua alemã, no intuito de fazer justiça à sua própria imposição formulada por volta do ano de 1912:
"Um grande poeta retórico ou epigramático pode ser lido em tradução, sendo ela boa; quem não sabe a língua, escusa, havendo essa boa tradução, de por tão pouco a estudar. Mas quem quiser ler um poeta lírico não pode aceitar tradução nenhuma, por fiel que seja à alma do poeta. Tem de aprender a língua em que a poesia foi escrita. [...]"
Sabendo-se que Fernando Pessoa nunca dominou a língua alemã, pretende-se, neste estudo, delinear o percurso da sua relação com esta língua e o modo como ela se liga à sua leitura de um autor que, embora em muito menor escala que Goethe, emerge nalguns pontos da actividade de Pessoa enquanto leitor crítico: Friedrich Schiller.
Ao apelo da Universidade de Coimbra para que, no âmbito da sua semana Cultural, as Faculdades e outros organismos que nela se acolhem glosem o tema da “Imaginação”, responde o Instituto de Estudos Alemães com o colóquio Imaginação do mesmo: a diferença na repetição. No texto que enquadra o conjunto de contributos que hoje aqui se apresentam, se afirma, a dado passo, que “Há inovação e transformação não na impossível invenção de uma origem, mas sim na capacidade de articulação produtiva”. Pode esta ser uma boa síntese daquilo que a moderna descendência da espécie homo leva a cabo, enquanto homo sapiens (sapiens) e, portanto, homo loquens, no exercício da faculdade que é, a um tempo, o seu mais poderoso instrumento de cognição e o mais eficaz e económico veículo de comunicação – competição e cooperação são, recordo, os principais pilares em que assenta o processo da sua sobrevivência enquanto espécie.
Criadas as línguas, de que espaço de manobra dispõe o “homem que fala”, que é também um homo socialis, para as recriar, reinventar, adaptando-as às sempre renovadas coordenadas sociológicas em que se situa e de que ele próprio é o arquitecto?
Zarathustra in den Tropen : der Text als Spirale der Wiederholung in Nietzsche und Robert Müller
(2010)
Der Einfluss Nietzsches auf die Autoren des Fin-de-Siècle und des so genannten „Expressionistischen Jahrzehnts“ wird unumstritten von der Kritik akzeptiert. Jedoch beschränkt sich diese Einschätzung auch in den jüngsten Abhandlungen (Ester 2001) aufgrund von Thesen aus den 70er Jahren (zum Beispiel die des kanonischen Bandes von Martens von 1971) auf den Parameter des Vitalismus. Die Untersuchungen zur Rezeption Nietzsches in dieser Zeit konzentrieren sich größtenteils auf 'Also sprach Zarathustra' und ignorieren oder unterschätzen somit andere philosophische Texte des Autors. Auf jeden Fall kann man den deutlichen Einfluss Nietzsches auf den deutschsprachigen Modernismus weder auf den 'Zarathustra' und sein vorherrschendes Thema den Übermenschen, noch auf die metaphysische Dimension seiner Philosophie beschränken, ein Umstand, den auch das fiktionale und essayistische Werk des Wiener Autors Robert Müller (1887-1924) musterhaft unter Beweis stellt. 'Der Mythos der Reise. Urkunden eines deutschen Ingenieurs' (1915) ist ein Beispiel für einen essayistischen Roman, der nicht nur direkt von der Philosophie Nietzsches, sondern auch gerade von der jeweiligen begrifflichen und diskursiven Methodologie sowie dem jeweiligen textuellen Konzept profitiert. Es handelt sich damit um Faktoren, die auch unter dem Zeichen des Essayismus gesehen werden müssen.
Navigare necesse est : de Magalhães a Vespúcio ; três navegadores reinventados por Stefan Zweig
(2010)
"Navigare necesse est" [...] Ao longo dos tempos, esta expressão de ousadia conservou-se no discurso literário da cultura ocidental. No século XX, serviram-se dela, por exemplo, dois autores indelevelmente inscritos na memória cultural da língua portuguesa: o poeta Fernando Pessoa, como vimos, e ainda o cantautor Caetano Veloso. […] Nesta linha de apropriação se situa também o escritor austríaco Stefan Zweig quando, em 1937, intitula “Navigare necesse est” o capítulo introdutório da biografia “Magellan. Der Mann und seine Tat”. Ao contrário dos autores de língua portuguesa acima mencionados, Zweig adopta apenas o primeiro segmento do axioma, pois no fenómeno de intertextualidade [...]. Zweig aproveita a expressão no enquadramento semântico original – as navegações –, para a aplicar à linhagem de bravos homens do mar e de eruditos cosmógrafos que tornaram possível a era dos Descobrimentos. Nesse capítulo inicial da narração biográfica, a voz autoral traça uma panorâmica da primeira fase das Descobertas, mostrando como o móbil económico, que desencadeou todo o processo, acabou por trazer à Humanidade ganhos de outra natureza. Assim, os Descobrimentos não terão permitido apenas chegar à Índia e às tão desejadas especiarias: a demanda corajosa e continuada ter-se-á justificado principalmente por desafiar os mitos do oceano, afastar os medos do mar e alargar a nossa dimensão do mundo.
Passaram já mais de vinte anos sobre a apresentação no Centro Pompidou, em Paris, da exposição 'Vienne, 1880-1938, naissance d'un siècle'. Tratou-se, como alguns se recordarão, de um acontecimento de grande repercussão em toda a Europa. A definitiva consolidação do mito cultural da “Viena de 1900” está estreitamente associada a este acontecimento. A ressonância do evento, contudo, não poderá ser cabalmente entendida se não se tiver presente que, em meados dos anos oitenta a controvérsia sobre o pós-modernismo estava no auge. A verdade é que o comissário da exposição, Jean Clair, programou-a expressamente como uma espécie de manifesto pós-moderno, à luz de uma interpretação da modernidade vienense como um sítio arqueológico maior da pós-modernidade. […] É evidente que esta afirmação distintamente pós-histórica e pós-filosófica se baseia numa imagem da 'Wiener Moderne' como lugar de uma critica implícita à narrativa do progresso como perpétua inovação. A actualidade da Viena de 1900 reside, aos olhos de Jean Clair, justamente, numa específica noção de temporalidade que é hostil à ideia do novo como ruptura irreversível […]. É este, de facto, o núcleo da “hipótese vienense”, para usar a expressão proposta na época por Paolo Portoghesi, um dos mais influentes teóricos da arquitectura pós-modernista nos anos oitenta (Portoghesi 1984). Não vou ocupar-me aqui dos equívocos, por vezes grotescos, gerados em torno dessa hipótese no âmbito da teoria do pós-modernismo. Vou, simplesmente, concentrar-me no conceito de repetição e nas suas consequências para um entendimento mais lato do paradigma modernista, já que, na verdade, a “hipótese vienense”, as lições literalmente excêntricas da 'Wiener Moderne', representam, no fundamental, a percepção do carácter aberto e plural das respostas modernistas à condição moderna.
O romance em apreço poderá […] ser compreendido com o resultado desta duplicidade identitária e interpretado como uma metáfora da amnésia social generalizada que o autor observa na sociedade onde actua. Neste texto é sua intenção criticar a ausência de altruísmo, a indiferença, o preconceito e as generalizações a que muitas das personagens do romance são sujeitas. Enquanto algumas destas figuras, especialmente as que pertencem a minorias negligenciadas, aspiram à sua integridade pessoal e ao reconhecimento social, as restantes figuras personificam a incapacidade de relembrar da qual a sociedade civil genericamente parece sofrer. Na visão de Rabinovici, devido a este esquecimento colectivo a sociedade incorre nos mesmos erros do passado, do passado nacional-socialista, na medida em que, adoptando o papel de mera espectadora, continua passivamente a ignorar a necessidade de legitimação e de aceitação de um conjunto de indivíduos.
Die Eigenheit der letzteren Welle von literarischen Texten mit dem Hintergrund der Flucht und Vertreibung – unter anderen Günter Grass 'Im Krebsgang' (2002), Tanja Dückers 'Himmelskörper' (2003), Christoph Heins 'Landnahme' (2004) – liegt nicht in der Thematik per se (seit dem Nachkrieg wurde die Flucht und Vertreibung von Schriftstellern aus verschiedenen ideologischen Hintergründen thematisiert und fiktionalisiert), sondern in der Problematik der transgenerationellen Übertragung dieser traumatischen Erfahrungen. Schwerpunkt dieser Werke ist nicht darzustellen, wie die Kriegsgeneration den Zusammenbruch des Dritten Reichs erlebte, sondern die Überlieferung und die Verarbeitung dieser Ereignisse im Familienkreis, d.h. die Vermittlung der Wirkung solcher Erlebnisse auf die folgenden Generationen (Kinder, Enkelkinder). […] Viele dieser Werke weisen auf die Massenvergewaltigungen (oder zumindest auf die Panik davor) im Kontext von Flucht und Vertreibung hin, widmen aber der sexuellen Gewalt keine besondere Aufmerksamkeit im Text. Ausnahmen sind Hans-Ulrich Treichels (BRD, 1952) 'Der Verlorene' (1998) und Reinhard Jirgls (DDR, 1953) 'Die Unvollendeten' (2003). Für die Mütter der Erzähler dieser Texte waren die deutsche Niederlage und der Heimatverlust eng mit sexuellem Missbrauch verbunden. Als unbewältigte Schatten auf dem Familienleben müssen solche Erfahrungen bei der Analyse der intrafamiliären und intergenerationellen Beziehungen unbedingt berücksichtigt werden. Ziel dieses Referats ist es, zu untersuchen, welche Strategien beide Texte für die Repräsentation der Vergewaltigung bevorzugen, welche Rolle die sexuelle Gewalt als Chiffre der deutschen Niederlage in ihnen spielt, und inwieweit diese traumatische Erfahrung als Trope für die Nachkriegsrealitäten der beiden deutschen Staaten und der Integration der Vertriebenen fungiert.
This paper is part of a broader research project, which involves the Brazilian Portuguese translation, with notes and commentaries, of the 'Gesammelte Schriften über Musik und Musiker' (On Music and Musicians) by the German composer Robert Schumann (1810-1856). In such a study, located on the border of language, literature, and music, methodology gains a double significance: firstly, the nature and extent of the incursions through fields which are autonomous in themselves, but connected in the document to be translated, not only requires unity, but also reveals the gaps the translator is exposed to; and secondly, the methodology not only defines the scientific premises of the work, but also brings to light its ethical dimension. With this in mind I have chosen a methodological approach which works in two complementary ways, with the act of translating always being the point of departure and arrival: (1) from the experience of translation and the identification of gaps and problems, followed by the registration of the first notes and comments, through systematic research in connected areas; and (2) the opposite way: from the research in related fields back to the translation and to the editing of notes and comments. Each step of the process is carefully registered, as well as the different versions of the translated text. Allowing methodology to take precedence is therefore an act of self-exposure and defense: on the one hand, it is a means of assuring visibility for the translator; on the other hand, it secures concrete parameters for judgment both by readers and critics.
Vor mehr als zehn Jahren beschrieb ich bereits Theorie und Praxis des Deutschunterrichts an der Universidade Aberta, ein Studienbereich, der 1996 auf Initiative von Maria Laura Bettencourt Pires (Direktorin des Bereichs der Fernstudien do Ensino a Distância) entstanden war. Doch sollte die Umsetzung des Regelwerks von Bologna an unserer Institution noch bis 2007 dauern. Portugal hatte diesen Vorgaben, die einen gemeinsamen europäischen Hochschulraum ermöglichen sollten, bereits 1999 zugestimmt. Sie werden im geänderten Hochschulrahmengesetz von 2005 berücksichtigt. Ihre Einführung an der Universidade Aberta fiel sowohl mit der Methode des E-learnings als auch mit der Einbettung der Germanistik in ein neues Kurssystem zusammen, die u.a. die Semestralisierung der Lehrfächer zur Vorraussetzung hatte. Diese Semestralisierung bedeutete die Verdoppelung der zu unterrichtenden Fächer, sowie ein Vielfaches der bisherigen Anzahl der Examen. Außerdem galt es zu berücksichtigen, dass der Lehrstoff der Literaturfächer (franz. und dt. Literatur) bis zu den Anfängen der jeweiligen nationalen Literaturen ausgedehnt werden sollte. Bis zu jenem Zeitpunkt wurde an der Universidade Aberta das Fach ‚Neuere deutsche Literaturgeschichte vom 18. Jh. (Aufklärung) bis zur Gegenwartsliteratur‘ gelehrt. Für unsere Germanistikabteilung war ich in einer Arbeitsgruppe dafür zuständig, Vorschläge zur Umstrukturierung (inkl. Semestralisierung) und Anpassung der ‚Línguas e Literaturas Modernas‘ (LLM) an das Regelwerk von Bologna auszuarbeiten.
Der Diskusprolaps und die damit verbundene Schmerzsymptomatik stellen ein
bedeutsames und zunehmendes Gesundheitsproblem dar. Nach Ausschöpfung der
Möglichkeiten einer konservativen Therapie ist die Möglichkeit einer Ozon/Sauerstoff-
Injektion in die Bandscheibe als Therapiealternative zur konventionell offen
chirurgischen Therapie in Erwägung zu ziehen. Das farblose und scharf riechende,
instabile Gas Ozon hat eine hohe Wasserbindungskapazität und vermag
Schmerzmediatoren vor Ort über mehrere Monate zu hemmen, wirkt
antiinflammatorisch und durchblutungsfördernd. Ozon wandelt sich im Körper in
Sauerstoff um und besitzt eine geringe Allergenität. Bislang konnte in Studien keine
Überlegenheit der anderen minimalinvasiven Verfahren gezeigt werden.
In unserer Studie untersuchten wir die Wirksamkeit und Sicherheit der Ozon/Sauerstoff-
Injektion an 34 Patienten. Es wurden keine Komplikationen bei der Anwendung der
Intervention festgestellt.
Ziel unserer Studie war es, bei den Patienten die Schmerzen nach einem
Bandscheibenvorfall zu verringern, bzw. Schmerzfreiheit zu erreichen. Außerdem sollte
evaluiert werden, ob sich das gemessene Volumen der lumbalen Bandscheibe
signifikant verringerte.
Das Bandscheibenvolumen wurde vor und nach der Intervention gemessen. Hierbei
ergab sich eine signifikante Volumenreduktion nach 1 Monat, sowie 3 und 6 Monate
nach der Intervention. 82,4 Prozent der Patienten verspürten eine Schmerzreduktion
oder Schmerzfreiheit 6 Monate nach der Ozon/Sauerstoff-Injektion. Somit ist das
Ergebnis der Ozon/Sauerstoff-Injektion als konkurrenzfähig zu anderen
minimalinvasiven Methoden zur Behandlung des lumbalen Bandscheibenvorfalls zu
sehen.
