Palinologia e taxonomia dos gêneros Elephantopus L., Orthopappus Gleason e Pseudelephantopus Rohr. (Subtribo Elephantopinae, Vernonieae- Asteraceae) ocorrentes no Brasil

A subtribo Elephantopinae tem sido alvo de poucos estudos taxonômicos e palinológicos, necessitando de uma reavaliação em seus limites. Assim, o presente estudo teve como proposta atualizar e ampliar o conhecimento de 13 espécies de Elephantopinae ocorrentes no Brasil através de um acurado estudo palinológico, da anatomia foliar e taxonômico, promovendo a delimitação das espécies dos gêneros Elephantopus (10 espécies) Orthopappus (uma espécie) e Pseudelephantopus (duas espécies)além de oferecer subsídios para posteriores análises filogenéticas. O material botânico utilizado foi obtido através de exsicatas depositadas nos herbários brasileiros e de material coletado em campo. Os grãos de pólen foram tratados pelo método acetolítico, sendo posteriormente mensurados, descritos, e analisados sob microscopia de luz e eletrônica de varredura. As eletromicrografias foram obtidas de grãos de pólen não acetolisados, as análises taxonômicas baseiam-se na metodologia clássica. A anatomia foliar deu-se através da metodologia usual. Os resultados mostram grãos de pólen médios, 3-porados, de exina equinolofada com malhas poligonais organizadas ou não em Elephantopus e Pseudelephantopus, podendo apresentar interrupção na malha poral em Elephantopus. Em Orthopapus os grãos de pólen são 3-colporados, de sexina subequinolofada. A anatomia foliar possibilitou a separação de E. hirtiflorus e E. riparius através da forma ou contorno da nervura principal (planoconvexo), nas demais espécies o contorno é biconvexo. As espécies apresentaram tricomas capitados bisseriados com 8 células, tricomas filamentosos 3-4 celulares, bem como filamentosos de célula distal globosa ou ovóide em E. biflorus, E. micropappus, E. tomentous e Orthopappus angustifolius. Registrou-se variação na ornamentação da cutícula podendo ser lisa ou estriada entre as espécies, bem como a presença de substâncias pécticas na epiderme e drusas nos parênquimas. Em relação aos microcaracteres florais, foram considerados de importância diagnóstica os lóbulos da corola, que variaram entre glandular, glabro e penicilado, este ultimo apenas em E. hirtiflorus, os ápices das anteras que variaram entre obtuso, retuso em E. hirtiflorus e apiculado, lancelolado em E. mollis e E. racemosus, a base da antera variou entre sagitada, caudada lisa em E. riparius e E. tomentosus e caudada em E. riparius. Os macrocaracteres que apresentaram maior valor taxonômico foram a cipsela e o papus, a organização das coflorescências, o número de flores por capítulo e limbo foliar. Neste trabalho aceitou-se a segregação dos três gêneros, com base nos caracteres analisados

'False, fleeting, perjured Clarence': pseudonymity and criminality in the writings of James Clarence Mangan

This article explores the significance of the adopted partial pseudonym “Clarence” to James Clarence Mangan (1803-1849), who is increasingly regarded as the most important Irish poet before W. B. Yeats. Tracing the literary history of “Clarence” from Shakespeare to Maria Edgeworth, this essay argues that the intriguing adoption exposes a preoccupation with themes of unlawful textual copying that is at the centre of Mangan’s imagination. These tropes assume singular significance when appreciated alongside Mangan’s profession as a scrivener. While literary criticism has separated Mangan the poet from Mangan the legal scribe, his hitherto under-explored assumption of “Clarence” provides a clue to their close and crucial connection. These themes of pseudonymity, copying, and criminality combine with particular resonance in his quasi-translation “The Man in the Cloak” (1838) to open up new perspectives on Mangan’s writing and its participation in wider European cultural contexts and concerns. The essay will conclude with a salient comparison of Mangan’s story with Nikolay Gogol’s seminal story “The Overcoat”, or, “The Cloak” (1842).

Gleason Upgrading with Time in a Large Prostate Cancer Active Surveillance Cohort

PURPOSE: We report the percentage of patients on active surveillance who had disease pathologically upgraded and factors that predict for upgrading on surveillance biopsies.

MATERIALS AND METHODS: Patients in our active surveillance database with at least 1 repeat prostate biopsy were included. Histological upgrading was defined as any increase in primary or secondary Gleason grade on repeat biopsy. Multivariate analysis was used to determine baseline and dynamic factors associated with Gleason upgrading. This information was used to develop a nomogram to predict for upgrading or treatment in patients electing for active surveillance.

RESULTS: Of 862 patients in our cohort 592 had 2 or more biopsies. Median followup was 6.4 years. Of the patients 20% were intermediate risk, 0.3% were high risk and all others were low risk. During active surveillance 31.3% of cases were upgraded. On multivariate analysis clinical stage T2, higher prostate specific antigen and higher percentage of cores involved with disease at the time of diagnosis predicted for upgrading. A total of 27 cases (15% of those upgraded) were Gleason 8 or higher at upgrading, and 62% of all 114 upgraded cases went on to have active treatment. The nomogram incorporated clinical stage, age, prostate specific antigen, core positivity and Gleason score. The concordance index was 0.61.

CONCLUSIONS: In this large re-biopsy cohort with medium-term followup, most cases have not been pathologically upgraded to date. A model predicting for upgrading or radical treatment was developed which could be useful in counseling patients considering active surveillance for prostate cancer.

Essays on James Clarence Mangan: The Man in the Cloak

This volume explores the extraordinary literary achievement of James Clarence Mangan (1803-1849), increasingly recognised as one of the most important Irish writers of the nineteenth century and a crucial influence on later writers such as W.B. Yeats and James Joyce. It is the first collection of essays to focus on Mangan, and features articles by leading scholars in the field (including Jacques Chuto and David Lloyd) as well as contributions from acclaimed contemporary writers, Paul Muldoon and Ciaran Carson. The collection expands existing fields of debate--translation, the supernatural, intertextuality, nationalism, romanticism-- and introduces new ones: Mangan's afterlife in the English literary canon, cosmopolitanism and Weltliteratur, antiquity and futurity, nineteenth-century spiritualism and magical thinking. 'The man in the cloak', one of Mangan's favourite pseudonyms, is still a a resonant soubriquet for a writer who has eluded sustained critical attention, and this volumes restores him to his proper place in European and British, as well as Irish literary history.
