Ecobiology of helminth parasites of finfishes and shellfishes of Cochin waters with special reference to Digenetic trematodes

The great number of parasitic species of marine and brackishwater animals that have been described indicates that parasites play an important part in the ecology of the oceans and brackishwaters. Jnspite of their importance, marine and brackish parasites are probably the least known group of organisms. Considering the large number of marine and brackishwater hosts, especially in the tropics, it is no exaggeration to say that the description of marine and brackishwater parasites has hardly begun (Rohde, 1982). With this view in mind, an attempt has been made to study the ecobiology of the helminth parasites of finfishes and shellfishes of eochin waters with special reference to digenetic trematodes. The work is broadly divided into three chapters, Chapter 1 consists of a description of the study area, prevalence of infection and concurrent infections with helminth parasites, seasonal variation, host specificity> and zoogeography of digenetic trematodes; Chapter II deals with the systematics of digenetic trematodes; and Chapter III deals with studies on larval trematodes from molluscs and crustacea, adult from a molluscan host, life-cycle, biology and histopathology

Dickens, Hogarth and artistic perception: the case of Nicholas Nickleby

This essay considers the interest shared by William Hogarth and Charles Dickens on the idea of instrumentality in the art of realism. Taking his cue from eighteenth-century epistemological philosophy, Hogarth developed an idea of beauty and realism as insisting upon the need for human subjectivity or perspective. Naïve realism was a style that troubled both Hogarth and Dickens and both men developed forms in which caricature, melodrama and exaggeration is crucial to the development of verisimilitude. Considering the progress pieces and the writings of Hogarth as a preface to the style of Dickens, I argue that Nicholas Nickleby developed an extraordinary self-reflexivity. Both Nicholas and his uncle Ralph form part of a narrative study of the implications of filtering perception through the distorting lens of the individual.

Políticas públicas de atendimento à criança: desafio da ação articulada no Projeto Belém Criança (2001-2004)

Public politics of Service to the Child: The Challenge of the Action Articulated in the Project Belém Criança (2001-2004) if it constitutes in a study on the politics directed toward the children of 0 the 6 years. It has as objective to analyze the configuration of the politics of integral attention to the child, evidencing the form as the same ones they had been redimensioned by the neoliberal ideas and by the lines of direction of the international organisms. The work has like empiric reference the project Belém Criança, developed by county of Belém from a partnership with the Deep of United Nations for Infancy (UNICEF), in the period of 2001 and 2004. The project intends to develop an articulated action among the several county departments which offer assistance to the children looking for to rationalize the resources and to optimize the services. Amongst the methodological procedures that materialized the research distinguished: The bibliographical review and documental allowed to analyze the contextualization of the public politics and, between them, the social politics of attendance to the child; the historical revolution this attendance; the paper of the UNICEF how articulator of the politics in municipal scope; and the paper of county how executer these politics. Still it was utilized, the half-structuralized interview, Having like subjects: the representative of the UNICEF in Belém, the municipal co-managers and actors of community in which the project was implemented. The result of the analyzes review that, historically, the politics destined to the child they had been being dimensioned having like support the fight of social movements vindictive for publics politic which guarantee the fundamentals rights these citizen. Although legal dimension of current politics of attendance to the child, to assume a vision of completeness and the guarantee of the rights, it still has a great exaggeration between the speech and the practical one. Actually, the same one are elaborate inside the neoliberal optics, with ruled actions by the beginning in combat to the poverty, implanted with low costs and with practice which to lead to the excessive fragmentation, generating inadequate actions and punctual programs which don t guarantee the social quality of the attendance. This perspective was evidenced to the most of the actors which the Project Belém Criança don t constitute itself a real public politic toward the child of 0 the 6 years, although present innovating aspects, how the mobilization and participation. It was demonstrated yet, in the participant s depositions of the research, that the bureau had numberless of difficulty to develop the action preview in the project, it has seen the great complexity of articulation between the several organism responsible by politics of attendance

Frenético e melodrama: os vampiros de Polidori e Nodier

Charles Nodier foi um dos grandes responsáveis pela divulgação do romance gótico ou roman noir na França, o qual passou a denominar “frenético”, remetendo ao exagero que caracterizaria esse tipo de literatura. No início do século XIX, no romantismo francês, uma intensa circulação estabelece-se entre o frenético e o melodrama em um intercâmbio de autores, motivos e procedimentos literários. A partir de 1820, o melodrama instala-se no sobrenatural, sobretudo com Le vampire de Nodier, composto em colaboração com Jouffroy e Carmouche; esse melodrama, adaptado do texto de Polidori, The vampire, publicado em 1819, harmoniza-se com o retorno de popularidade por que passa o gothic novel. Essa união do frenético ao melodrama deixa ver duas tendências literárias bastante fecundas no romantismo francês, que se irmanam ainda no sentido em que respondem aos anseios de um público fatigado por séculos de racionalismo e ávido por toda a espécie de sensações e sentimentos.

O Recuo Brutalista

Em conformidade com a dúvida de seu título, o difundido livro The New Brutalism: Ethic or Aesthetic? de Reyner Banham não é possível explicar o Brutalismo como manifestação artística coesa, dotada de consistência e reprodutibilidade formal. A citação de arquitetos famosos, porém divergentes, parece associar e comparar obras ásperas com a pretensão de reerguer uma arquitetura moderna considerada ascética, monótona e insuficiente e gera um teoricismo da aparência crua e do moralismo dos objetos. Discurso que oculta, ou desvia a atenção do retorno artístico à sublimidade e construção artesanal. O Brutalismo é aceito como evolução natural dos estágios modernos anteriores e sanciona artefatos toscos, pesados e inacabados como se fossem filiados ao processo moderno desinfestado. Esconde contradições e disfarça seu rompimento com o moderno para prolongar a expressão Movimento moderno. Mas o objeto claro, econômico e preciso é repudiado pelo consumidor e, por ser pouco representativo, o artista faz sua maquiagem com episódios contrastantes e monumentais na informalidade das cidades espontâneas. No entanto, parece possível suspender a noção positiva e corretiva do Brutalismo para entendê-lo como um recuo artístico vulgarizador que despreza aperfeiçoamento e afronta a atitude moderna com banalização conceptiva, exagero, figuralidade, musculação estrutural, grandeza tectônica, rudimento e rudeza. Assim, moralismo, retorno rústico e originalidade desqualificam a expressão International Style entendida como a culminação da arquitetura moderna do pós-guerra, ao depreciá-la como decadente, como produto imobiliário, comercial e corporativo a serviço do capital. Essa interpretação desvela uma crítica anti-industrial, portanto antimodernista e diversa da pós-modernidade, porém contestadora e realista para fornecer imagens à cultura e aos insensíveis à estrutura da forma moderna. Diverso da pós-modernidade pela dependência ao moderno e ausência de apelo popular. Tornada insignificante a configuração oportuna do artefato, o arquiteto tenta reter sua notabilidade artística, ou o prestígio que parece enfraquecer na aparência símile da especificação de catálogo, no rigor modular. Indispõe-se e repudia componentes, Standards e acabamentos impessoais da indústria da construção para insistir em autoria e inspiração, mas repete cacoetes estilísticos de época e o inexplicável uso intensivo de concreto bruto e aparente para sentir-se engajado e atualizado. Porém, é necessário distinguir obras de aparência severa concebidas pela atitude moderna mais autêntica das de concreto aparente em tipos ou configurações aberrantes. Para avançar na discussão do Brutalismo propõe-se entender este fenômeno com a substituição do juízo estético moderno de sentido visual postulado por Immanuel Kant (1724-1804) por um sentimento estético fácil e relacionado com a sensação da empatia, com a Einfühlung de Robert Vischer (1847-1933). Na época da cultura de massas, admite-se o rebaixamento das exigências no artefato e a adaptação brutalista com a transfiguração dos processos de arquitetura moderna. Assim, a forma é substituída pela figura ou pelo resumo material; a estrutura formal subjacente pelo ritmo e exposição da estrutura física; o reconhecimento visual pelo entusiasmo psicológico ou pelo impulso dionisíaco; a concepção substituída pelo partido, ou, ainda, pelo conceito; a sistematização e a ordem pela moldagem e a organização; a abstração e síntese pela originalidade e essencialidade, o sentido construtivo pela honestidade material; a identidade das partes pela fundição ou pela unicidade objetal e a residência pela cabana primitiva.

Influence of reported study design characteristics on intervention effect estimates from randomized, controlled trials

Published evidence suggests that aspects of trial design lead to biased intervention effect estimates, but findings from different studies are inconsistent. This study combined data from 7 meta-epidemiologic studies and removed overlaps to derive a final data set of 234 unique meta-analyses containing 1973 trials. Outcome measures were classified as "mortality," "other objective," "or subjective," and Bayesian hierarchical models were used to estimate associations of trial characteristics with average bias and between-trial heterogeneity. Intervention effect estimates seemed to be exaggerated in trials with inadequate or unclear (vs. adequate) random-sequence generation (ratio of odds ratios, 0.89 [95% credible interval {CrI}, 0.82 to 0.96]) and with inadequate or unclear (vs. adequate) allocation concealment (ratio of odds ratios, 0.93 [CrI, 0.87 to 0.99]). Lack of or unclear double-blinding (vs. double-blinding) was associated with an average of 13% exaggeration of intervention effects (ratio of odds ratios, 0.87 [CrI, 0.79 to 0.96]), and between-trial heterogeneity was increased for such studies (SD increase in heterogeneity, 0.14 [CrI, 0.02 to 0.30]). For each characteristic, average bias and increases in between-trial heterogeneity were driven primarily by trials with subjective outcomes, with little evidence of bias in trials with objective and mortality outcomes. This study is limited by incomplete trial reporting, and findings may be confounded by other study design characteristics. Bias associated with study design characteristics may lead to exaggeration of intervention effect estimates and increases in between-trial heterogeneity in trials reporting subjectively assessed outcomes.

Genetic analysis of factors regulating mesenchymal cell fates

Formation of cartilage and bone involves sequential processes in which undifferentiated mesenchyme aggregates into primordial condensations which subsequently grow and differentiate, resulting in morphogenesis of the adult skeleton. While much has been learned about the structural molecules which comprise cartilage and bone, little is known about the nuclear factors which regulate chondrogenesis and osteogenesis. MHox is a homeobox-containing gene which is expressed in the mesenchyme of facial, limb, and vertebral skeletal precursors during mouse embryogenesis. MHox expression has been shown to require epithelial-derived signals, suggesting that MHox may regulate the epithelial-mesenchymal interactions required for skeletal organogenesis. To determine the functions of MHox, we generated a loss-of-function mutation in the MHox gene. Mice homozygous for a mutant MHox allele exhibit defects of skeletogenesis, involving the loss or malformation of craniofacial, limb and vertebral skeletal structures. The affected skeletal elements are derived from the cranial neural crest, as well as somitic and lateral mesoderm. Analysis of the mutant phenotype during ontogeny demonstrated a defect in the formation or growth of chondrogenic and osteogenic precursors. These findings provide evidence that MHox regulates the formation of preskeletal condensations from undifferentiated mesenchyme. In addition, generation of mice doubly mutant for the MHox and S8 homeobox genes reveal that these two genes interact to control formation of the limb and craniofacial skeleton. Mice carrying mutant alleles for S8 and MHox exhibit an exaggeration of the craniofacial and limb phenotypes observed in the MHox mutant mouse. Thus, MHox and S8 are components of a combinatorial genetic code controlling generation of the skeleton of the skull and limbs. ^

Improving Cervical Cancer Nodal Boost Radiation Therapy by Quantifying Uncertainties and Exploring Advanced Radiation Therapy Modalities

Radiation therapy for patients with intact cervical cancer is frequently delivered using primary external beam radiation therapy (EBRT) followed by two fractions of intracavitary brachytherapy (ICBT). Although the tumor is the primary radiation target, controlling microscopic disease in the lymph nodes is just as critical to patient treatment outcome. In patients where gross lymphadenopathy is discovered, an extra EBRT boost course is delivered between the two ICBT fractions. Since the nodal boost is an addendum to primary EBRT and ICBT, the prescription and delivery must be performed considering previously delivered dose. This project aims to address the major issues of this complex process for the purpose of improving treatment accuracy while increasing dose sparing to the surrounding normal tissues. Because external beam boosts to involved lymph nodes are given prior to the completion of ICBT, assumptions must be made about dose to positive lymph nodes from future implants. The first aim of this project was to quantify differences in nodal dose contribution between independent ICBT fractions. We retrospectively evaluated differences in the ICBT dose contribution to positive pelvic nodes for ten patients who had previously received external beam nodal boost. Our results indicate that the mean dose to the pelvic nodes differed by up to 1.9 Gy between independent ICBT fractions. The second aim is to develop and validate a volumetric method for summing dose of the normal tissues during prescription of nodal boost. The traditional method of dose summation uses the maximum point dose from each modality, which often only represents the worst case scenario. However, the worst case is often an exaggeration when highly conformal therapy methods such as intensity modulated radiation therapy (IMRT) are used. We used deformable image registration algorithms to volumetrically sum dose for the bladder and rectum and created a voxel-by-voxel validation method. The mean error in deformable image registration results of all voxels within the bladder and rectum were 5 and 6 mm, respectively. Finally, the third aim explored the potential use of proton therapy to reduce normal tissue dose. A major physical advantage of protons over photons is that protons stop after delivering dose in the tumor. Although theoretically superior to photons, proton beams are more sensitive to uncertainties caused by interfractional anatomical variations, and must be accounted for during treatment planning to ensure complete target coverage. We have demonstrated a systematic approach to determine population-based anatomical margin requirements for proton therapy. The observed optimal treatment angles for common iliac nodes were 90° (left lateral) and 180° (posterior-anterior [PA]) with additional 0.8 cm and 0.9 cm margins, respectively. For external iliac nodes, lateral and PA beams required additional 0.4 cm and 0.9 cm margins, respectively. Through this project, we have provided radiation oncologists with additional information about potential differences in nodal dose between independent ICBT insertions and volumetric total dose distribution in the bladder and rectum. We have also determined the margins needed for safe delivery of proton therapy when delivering nodal boosts to patients with cervical cancer.

¿Le temía Claudio a la muerte? (Suetonio, Claudio 43-46)

Todas las fuentes antiguas presentan el ascenso al poder de Claudio como un evento fortuito. De acuerdo con ellas, Claudio fue emperador por casualidad y todo su imperio se caracterizó por la inseguridad y la inestabilidad. Tan gran inestabilidad caracterizó todo su gobierno que era natural que él sintiera miedo. Pero este defecto, el temor, aparece notablemente exagerado por Suetonio, quien dedica varios capítulos a su descripción. Sin embargo, cuando llega el momento de narrar la muerte de Claudio y su decisión de favorecer a su hijo Británico en su ascenso al trono y el coraje que esta decisión implicó, Suetonio presenta una narración de los hechos simple y reducida. Suetonio ha disminuido intencionalmente la importancia de este último acto de Claudio, narrándolo de una manera muy simple y concisa, sin comentarios, sin interpretación, a la vez que ha enfatizado y exagerado los defectos del emperador, el miedo y la crueldad. El propósito de este artículo es, por lo tanto, mostrar la tendenciosidad del relato de Suetonio y rescatar la imagen del emperador injustamente vilipendiado

"Contra toda forma de opresión" : Sexo, política y clases medias juveniles en las revistas de humor de los primeros '70

Este artículo explora cómo las revistas de humor político-cultural de los primeros '70 devinieron una fuente de autorreflexión para un público, o espacio social, que se constituyó en torno a ellas. A partir del análisis de la más importante de esas publicaciones, Satiricón, es posible aseverar que en términos socio-demográficos ese espacio social se componía de segmentos juveniles de los sectores medios intelectualizados que podían a la vez reírse y hacer reír, en especial cuando se remarcaban incongruencias en sus experiencias sexuales y políticas. Las revistas de humor elaboraron múltiples incongruencias: los llamados a una educación sexual imbricados con la persistencia de viejas creencias sexuales; el lenguaje "psi" domesticando, antes que ayudando a liberar, las represiones sexuales; los varones temiendo por el fin de privilegios ante la afirmación sexual de las mujeres; y, más en general, la militancia política como forma de opresión. Las incongruencias eran la base de lo risible, mientras que en su centro estaban los y las jóvenes de los sectores medios, a quienes se convocaba a un tipo de reflexión que, en ese contexto político, quizá era solo viable a partir de la exageración y del humor
