Um género sui generis : o Teatro de Aforismos de Vicente Sanches
No full textEsta tese descreve aquilo que o dramaturgo português Vicente Sanches designa por Teatro de Aforismos. O Teatro de Aforismos, segundo o seu autor, é uma forma teatral, uma espécie de género ou estilo literário. Contudo, as peças que integram este teatro apresentam formas muito distintas, que sugerem uma constante modificação deste estilo. Alguns destes textos não se assemelham ao que habitualmente reconhecemos como peças de teatro, e o uso de palavras como “aforismo”, “teatro”, “personagem” ou “didascália” é muitas vezes estranho.
Nestas peças de aforismos “sui generis” expõem-se essencialmente ideias, uma vez que é isso que mais interessa, em detrimento da acção e de personagens concretas. A descrição que apresento do Teatro de Aforismos centra-se na forma como Sanches utiliza esta espécie de teatro para pensar sobre Deus, sobre a morte e a loucura e, especialmente, como é que esta forma teatral representa a concepção que o dramaturgo tem da sua obra e da arte que pratica. Esta última ideia, no fundo, reflecte a proibição que Sanches impôs à encenação dos seus textos e a importância da leitura e da imaginação em detrimento do espectáculo e da acção.This thesis describes the Theatre of Aphorisms, as labeled by the Portuguese playwright Vicente Sanches. According to its author, the Theatre of Aphorisms is a theatrical form, a kind of literary genre or style. However, the plays within this theatre manifest very diverse forms, suggesting a constant modification of this style. Some of these texts do not resemble what is commonly recognized as plays, and words such as “aphorism”, “theatre”, “character”, or “stage direction” are often employed unconventionally.
In this “sui generis” aphorism plays, the primary focus is on showcasing ideas, as that is what matters most, often to the detriment of both action and concrete characters. This description of the Theatre of Aphorisms centres on Sanches’s way to use theatre to contemplate God, death, and madness, and, especially, how this theatrical form represents the playwright’s conception of his work and the art he practices. This last idea ultimately reflects Sanches’ prohibition on staging his texts and underscores the importance of reading and imagination over spectacle and action

Computational tools for the structural and functional study of dermatophytes genes potentially involved in pathogenicity
No full textDermatófitos são fungos filamentosos que infectam substratos queratinizados como pele, unha e cabelo em busca de nutrientes para se desenvolverem e permanecerem no hospedeiro. Pertencem aos gêneros Epidermophyton, Microsporum ou Trichophyton, os quais, dependendo de seu habitat natural, são classificados em espécies geofílicas, zoofílicas ou antropofílicas. O uso indiscriminado de antifúngicos levou à seleção de cepas resistentes, e o comportamento invasivo desses patógenos em pacientes imunodeprimidos aumentou nos últimos anos, dificultando o tratamento das dermatofitoses. Há, portanto, a necessidade de estudos para um melhor entendimento da biologia dos dermatófitos devido as suas importâncias médica e/ou veterinária e o escasso conhecimento da interação destes patógenos com os hospedeiros. No presente trabalho, analisamos oito espécies de dermatófitos: Arthroderma benhamiae, Microsporum canis, Microsporum gypseum, Trichophyton interdigitale, Trichophyton equinum, Trichophyton rubrum, Trichophyton tonsurans e Trichophyton verrucosum. Análises de genômica comparativa e de expressão de genes potencialmente envolvidos na degradação de queratina foram realizadas. Além disso, efetuamos o sequenciamento genômico em larga escala de uma das linhagens. A estrutura dos genes sub3, sub5 e sub7, que codificam serina endopeptidases com atividade queratinolítica, mep3 e mep4, que codificam proteínas pertencentes ao grupo das metaloendopeptidases, dppV, lap1 e lap2, que codificam exopeptidases, foi analisada por meio de ferramentas computacionais. Essas análises revelaram que os genes que codificam proteases possuem alto grau de conservação em suas estruturas, que é menor quando comparadas apenas suas regiões não codificadoras. As análises permitiram também a identificação em regiões promotoras de consensos específicos a gêneros de dermatófitos. Observamos que o acúmulo de transcritos destes genes, avaliados durante o cultivo em queratina, mimetizando o processo infeccioso, não está correlacionado à similaridade das sequências gênicas entre as espécies. Não encontramos correlação entre o nicho preferencial dos dermatófitos e suas sequências gênicas ou níveis transcricionais. Observamos que, na grande maioria das vezes, genes que codificam endo e exopeptidases, possuem acúmulo de transcritos em períodos iniciais de degradação de queratina. Nossos resultados sugerem que diferenças pontuais na sequencia gênica, diferenças em regiões promotoras ou, até mesmo, expressão variável destes genes que codificam um conjunto proteico com funções sinérgicas e provavelmente compensatórias, contribuam para os diferentes graus de reações inflamatórias no hospedeiro, bem como para a especificidade patógeno-hospedeiro.Dermatophytes are filamentous fungi that infect keratinized substrates such as skin, nail and hair, searching for nutrients for their development and permanence in the host. They belong to the genera Epidermophyton, Microsporum or Trichophyton, and, depending on their natural habitat, are classified into geophilics, zoophilics or anthropophilics species. The indiscriminate use of antifungals has led to the selection of resistant strains, and the invasive behaviour of these pathogens in immunocompromised patients increased in the last years, hampering the treatment of the dermatophytoses. Therefore, there is a need of studies for a better understanding of the biology of the dermatophytes due to their medical and/or veterinary importance and the scarce knowledge about the interaction of these pathogens with their hosts. In this work, we analyzed eight species of dermatophytes: Arthroderma benhamiae, Microsporum canis, Microsporum gypseum, Trichophyton interdigitale, Trichophyton equinum, Trichophyton rubrum, Trichophyton tonsurans, and Trichophyton verrucosum. Comparative genomics and gene expression analyses of genes potentially involved in keratin degradation were performed. Moreover, we performed a large-scale genome sequencing of one of the strains. The structure of the genes sub3, sub5, and sub7, which encode serine endopeptidases with keratinolytic activity, mep3, and mep4, which encode proteins belonging to the group of the metalloendopeptidases, dppV, lap1, and lap2, encoding exopeptidases, were analyzed by computational tools. These analyses revealed that the genes encoding proteases possesses high degree of conservation in their structures, which are lower when their non-coding regions are compared. The analyses also allowed the identification of consensus in promoter regions, specific of dermatophytes genera. We observed that the transcripts accumulation of these genes, evaluated during the cultivation in keratin, mimicking the infection process, is not correlated to the gene sequence similarities among the species. We have not found any correlation between the preferential niche of dermatophytes and their gene sequences or transcription levels. Most of the times, we observed that genes encoding endo and exopeptidases accumulated transcripts at the beginning of keratin degradation. Our results suggest that specific differences in the genic sequencing, differences in promoter regions, or even variable expression of these genes encoding a set of proteins with synergic and probably compensatory functions, contribute to different levels of inflammatory reactions in the host, as well as to the host-pathogen specificity
Responsabilidade civil pelo abandono afetivo nas relações paterno-filiais
No full textTCC(graduação) - Universidade Federal de Santa Catarina. Centro de Ciências Jurídicas. Direito.Diante da complexidade atinente às relações familiares, em especial às relações paterno-filiais, e da premente necessidade de tutelar o direito de toda criança e adolescente ao seu pleno desenvolvimento para a vida em sociedade, visa o presente trabalho a consagrar a aplicação dos institutos da responsabilidade civil pelo não cumprimento dos deveres parentais perante sua prole, vista sob um prisma que lhe é peculiar. Por meio deste trabalho monográfico, buscar-se-á arrolar todo um arcabouço normativo e principiológico existente para garantir à criança e ao adolescente, enquanto sujeitos de direitos e seres em desenvolvimento, o direito à prestação afetiva e ao convívio familiar, tão essenciais à sua criação quanto o próprio alimento que lhe sustenta. Visualizar-se-ão as normas atinentes à configuração da responsabilidade civil por danos extrapatrimoniais, seus elementos, pressupostos e excludentes, tendo por escopo demonstrar que é legalmente permitida a condenação de genitores omissos quanto às suas obrigações perante os filhos, desde que observadas essas regras. Ao cabo, perquirir-se-á a aplicação fática dos institutos estudados quando submetidos ao crivo do Poder Judiciário de Santa Catarina e o atual ponto de vista do Superior Tribunal de Justiça acerca do assunto. Observando que não se faz cediço o entendimento pelos aplicadores do direito sobre o tema proposto, pretende-se, ainda, tecer algumas considerações sobre as dificuldades percebidas para a uniformização da compreensão em torno do assunto e sua consequente aplicação nas cortes brasileiras
Differential expression of multidrug-resistance genes in Trichophyton rubrum: DOI: 10.5584/jiomics.v9i2.304
No full textTreatment of dermatophytosis is generally a long and challenging process, deeply affected by drug resistance owing to efflux-mediated activity. These drug-pumping mechanisms involve overexpression of transporter proteins with the ability to extrude a wide variety of structurally and functionally unrelated compounds. The ATP-binding cassette transporter and the major facilitator are the two largest superfamilies of transporters, expressed ubiquitously in all living organisms. Here, we examined the transcription modulation of both families of transporter genes in the dermatophyte Trichophyton rubrum upon challenge with sub-lethal doses of undecanoic acid or acriflavine. Data derived from RNA sequencing revealed transporters functioning in specific patterns according to the stressing condition, suggesting that each drug recruits specific physiological pathways. Synergistic transport activity may be acting to overcome drug toxicity, demonstrating that multidrug resistance transporters cooperate to induce drug resistance and fungal survival in an unpredictable manner

Fourth abdominal tergite entirely smooth, except for basigastral costulae. Basigastral costulae short; in dorsal view, its length about a third of postpetiole length. SETAE. Cephalic and mesosomal ground-setae spatulate (Fig. 2A). Metasomal setae elongate-spatulate to remiform. Apicoscrobal setae absent (Fig. 2A). Pair of erect setae on cephalic dorsum close to occipital margin present. Anterior margin of scape with one or more spatulate setae curved towards antennal insertion. Humeral setae absent and mesonotal setae present (but see Comments below). HEAD. Masticatory margin of mandible with three to five denticles between apicodorsal tooth and submedian tooth, with two to four denticles proximal of submedian tooth (Fig. 2A). Apex of mandible with unknown number of intercalary denticles (but see Fig. 2A and Comments section for variation). Anterior clypeal margin, in dorsal view, slightly angular and projecting anteriorly. Eye, in lateral view, with four to five ommatidia in longest row. Eye on anterior half of head. In dorsal view, scape narrows basally; anterior margin expanded and almost lobate near subbasal bend. Third flagellomere smaller than fourth flagellomere; length of former only a third of length of latter. MESOSOMA. Humerus with small angular projection. Dorsum of mesonotum, in lateral view, slightly higher than dorsum of pronotum. Metanotal groove weakly impressed. Propodeal spine relatively long and triangular, linked to propodeal lobe by narrow lamella that extends throughout propodeal declivity. Femoral bulla ovate and located distally on dorsal margin of sclerite. METASOMA. Petiolar node, in dorsal view, slightly wider than long; in lateral view, anterior margin slightly longer than dorsal margin. Postpetiole, in lateral view, swollen and globular.Anterior margin of postpetiole, in dorsal view, medially concave. Ventral spongiform process of petiole absent. Ventral spongiform lobe of postpetiole minute to absent (Fig. 2B). Lateral spongiform lobe of postpetiole reduced to a narrow lamella (Fig. 2B). Ventral basigastral spongiform pad (= specialized setae on fourth abdominal sternite) small. Comments Bolton (2000) considered S. crassicornis as a member of the crassicornis complex (i.e., a cluster of species in the gundlachi species group), along with Strumigenys aethegenys (Bolton, 2000), S. auctidens (Bolton, 2000), S. brevicornis Mann, 1922, S. crementa (Bolton, 2000), S. metopia (Brown, 1959), S. myllorhapha (Brown, 1959), S. pasisops (Bolton, 2000), S. stenotes (Bolton, 2000), and S. zeteki (Brown, 1959). Members of the crassicornis complex are defined by the following traits (Bolton 2000): (i) inner margin of mandible with a submedian tooth or denticle near midlength; (ii) inner margin of mandible with smaller teeth between apicodorsal tooth and submedian tooth; (iii) three to five intercalary teeth; (iv) labral lobes long and slender; and (v) setae on apices of labral lobes short (i.e., with the same size or shorter than the labral lobes). According to Bolton (2000), different series of this species show slight variation in setae and sculpture, although maintaining the diagnostic traits for the species. He mentioned that some specimens possibly have short filiform humeral setae, although this condition was not observed in the type specimen and a few other individuals observed in this study. Additionally, a pair of mesonotal erect simple setae, which was not mentioned by Mayr (1887) nor Bolton (2000) in their descriptions, was also observed in the lectotype and a few other specimens. Humeral and mesonotal setae are apparently lost during the lifetime of the ants, since many specimens, otherwise well preserved, did not have those setae and most of the ones which did have them appear to be young adults by the appearance of their cuticle. Also, some specimens had an extremely reduced lateral spongiform lobe in the postpetiole, appearing vestigial, agreeing with the description made by Bolton (2000). In Bolton’s (2000) description, the author mentions that S. crassicornis have three to four minute intercalary teeth. Since we did not had access to the physical lectotype specimen, we could not confirm this condition. However, while studying other non-type specimens, we observed that the intercalary dentition consists of up to six to seven teeth. Interestingly, these intercalary teeth count does not agree with the diagnosis proposed by Bolton (2000) for the crassicornis complex. In specimens collected in Orleans and Tunas do Paraná (cf. list of examined materials), the katepisternum appears entirely reticulate-punctate, without smooth patches whatsoever. Different specimens collected in the same square meter (from Winkler leaf-litter samples) possess both reticulate-punctate katepisternum and various degrees of smoothness. One specimen from Viçosa (Minas Gerais State) and one specimen from the Reserva Biólogica Augusto Ruschi (Espírito Santo State) also have an entirely reticulate-punctate katepisternum. In Viçosa, all the other specimens examined matched the lectotype in having a smooth katepisternum. The morphological variability in this particular character, summed with the higher intercalary teeth count found in some non-type specimens observed, reinforces the need for a reevaluation of the boundaries of this species. In the Amazonian region, non-type specimens identified as S. crassicornis tend to depart further from the lectotype, differing in one or more traits, and do not entirely match the species’ diagnosis. One specimen from Primavera (Pará State) has shallow reticulation on fourth abdominal tergite. A couple of specimens from Amazonas state (vicinities of Manaus; cf. additional material examined ZF-02) have an almost entirely reticulate-punctate katepisternum and shallow reticulation on fourth abdominal tergite. A specimen from Canarana (Mato Grosso State) has shallow reticulation on fourth abdominal tergite and humeral and mesonotal setae which are not simple, but slightly flattened and subflagellate. A couple of specimens, also from Primavera, have shallow reticulation on fourth abdominal tergite, basigastral costulae absent, spongiform process on postpetiole absent, and smaller and less abundant metasomal erect setae. Finally, one specimen from “Jaci Novo’’ (Rondônia State) is much larger than all examined specimens, has both humeral and mesonotal setae flattened and subflagellate, and a comparatively larger postpetiole, with shallow reticulation on fourth abdominal tergite.Published as part of Silva, Thiago Sanches Ranzani Da, Chaul, Júlio Cezar Mário & Feitosa, Rodrigo Machado, 2022, Lectotype designation and redescription of four commonly collected Neotropical species of Strumigenys (Hymenoptera: Formicidae), pp. 103-126 in European Journal of Taxonomy 798 (1) on pages 106-111, DOI: 10.5852/ejt.2022.798.1673, http://zenodo.org/record/634210

Fourth abdominal tergite superficially reticulate-punctate near base. Length of basigastral costulae, in dorsal view, more or less equal to length of postpetiole. SETAE. Cephalic ground-setae remiform (Fig. 4A). Two pairs of remiform erect setae on cephalic dorsum; one pair near medial region of head, other near occipital margin. Apicoscrobal setae flagellate (Fig. 4A). Anterior margin of scape with one or more remiform setae curved towards antennal insertion. Humeral setae flagellate (Fig. 4B).

Apex of mandible with two minute intercalary denticles (Fig. 4A). Anterior clypeal margin, in dorsal view, convex medially. Eye, in lateral view, with three to four ommatidia along longest row. Eye on anterior half of head. In dorsal view, scape cylindrical. Third flagellomere smaller than fourth flagellomere; length of former only one-third of length of latter. MESOSOMA. Humerus with small angular projection. Dorsum of mesonotum, in lateral view, convex, confluent with dorsum of pronotum. Metanotal groove weakly impressed, almost absent in lateral view. Propodeal spine relatively long and triangular, linked to propodeal lobe by narrow carina that extends throughout propodeal declivity. Femoral bulla small, ovate and located distally on dorsal margin of sclerite. METASOMA. Petiolar node, in dorsal view, slightly wider than long, almost as long as wide; in lateral view, anterior margin almost as long as dorsal margin. Anterior margin of postpetiole, in dorsal view, concave. Lateral and ventral spongiform processes of petiole absent. Ventral spongiform lobe of postpetiole minute (Fig. 4B).

Comments Bolton (2000) considered S. denticulata as a member of the gundlachi complex (i.e., a cluster of species under the gundlachi species group), along with Strumigenys connectens Kempf, 1958, S. decipula (Bolton, 2000), S. eggersi Emery, 1890, S. enopla (Bolton, 2000), S. gemella Kempf, 1975, S. gundlachi (Roger, 1862), S. jamaicensis Brown, 1959, S. laevipleura Kempf, 1958, S. lalassa (Bolton, 2000), S. nubila Lattke & Goitía, 1997, S. subedentata Mayr, 1887, S. trieces Brown, 1960, S. vartana (Bolton, 2000), and S. xenognatha Kempf, 1958. Members of the gundlachi complex are defined by the following traits (Bolton 2000): (i) inner margin of mandible without a submedian tooth or denticle near midlength; (ii) inner margin of mandible with several teeth of different sizes posterior to the apicodorsal tooth; (iii) two (rarely three) intercalary teeth; (iv) labral lobes short; and (v) setae on apices of labral lobes long (i.e., longer than the labral lobes). According to Bolton (2000), specimens belonging to S. denticulata have a wide range of mandibular length variation, with individuals collected in a single leaf litter sample presenting MIs ranging from 72 to 85. It is important to notice that the MI of the lectotype falls near the maximum value established by Bolton (i.e., MI 84.9). On the other hand, ML and HL measurements fall well within the range proposed by the same author as diagnosable for the species (i.e., ML 0.355 and HL 0.418). According to Bolton (2000), some specimens identified as S. denticulata have the katepisternum entirely reticulate-punctate, while all specimens observed in this study (cf. examined material) have a smooth patch in the katepisternum, including the lectotype. All specimens observed had the fourth abdominal tergite mostly smooth, only with the base of the sclerite with reticulate-punctate sculpture. One of the paralectotypes (BMNH(E)1013551) is missing the postpetiole and gaster, rendering it impossible to evaluate morphological variability of those body regions in this particular individual.Published as part of Silva, Thiago Sanches Ranzani Da, Chaul, Júlio Cezar Mário & Feitosa, Rodrigo Machado, 2022, Lectotype designation and redescription of four commonly collected Neotropical species of Strumigenys (Hymenoptera: Formicidae), pp. 103-126 in European Journal of Taxonomy 798 (1) on pages 111-116, DOI: 10.5852/ejt.2022.798.1673, http://zenodo.org/record/634210
