The rock-wallaby genus Petrogale comprises a group of habitat-specialist macropodids endemic to Australia. Their restriction to rocky outcrops, with infrequent interpopulation dispersal, has been suggested as the cause of their recent and rapid diversification. Molecular phylogenetic relationships within and among species of Petrogale were analysed using mitochondrial (cytochrome oxidase c subunit 1, cytochrome b. NADH dehydrogenase subunit 2) and nuclear (omega-globin intron, breast and ovarian cancer susceptibility gene) sequence data with representatives that encompassed the morphological and chromosomal variation within the genus, including for the first time both Petrogale concinna and Petrogale purpureicollis. Four distinct lineages were identified, (1) the brachyotis group, (2) Petrogale persephone, (3) Petrogale xanthopus and (4) the lateralis-penicillata group. Three of these lineages include taxa with the ancestral karyotype (2n = 22). Paraphyletic relationships within the brachyotis group indicate the need for a focused phylogeographic study. There was support for P. purpureicollis being reinstated as a full species and P. concinna being placed within Petrogale rather than in the monotypic genus Peradorcas. Bayesian analyses of divergence times suggest that episodes of diversification commenced in the late Miocene-Pliocene and continued throughout the Pleistocene. Ancestral state reconstructions suggest that Petrogale originated in a mesic environment and dispersed into more arid environments, events that correlate with the timing of radiations in other arid zone vertebrate taxa across Australia.

[ES]Este trabajo estudia la obra poética que dedica la autora feminista y anglo-francesa Michèle Roberts al mito de Deméter y Perséfone. A través de seis poemas presentados correlativamente, Roberts recorre la historia mitológica de dos mujeres simbólicas para reescribir y reinterpretar distintas percepciones del mito que engloba a las heroínas. Pasado y presente se corresponden, así como las valoraciones de la alegoría ficticia y la cultura contemporánea. En los poemas de Roberts, las narrativas en primera y tercera persona se entrelazan para tratar diversos temas como la relación entre madre e hija, el matrimonio, el ataque sexual, la identidad de las protagonistas, el inconsciente, el nacimiento y la muerte.

This essay analyzes the story and the culture of Italian American women, in particular how they are treated in the novel "Umbertina" by Helen Barolini. The essay first introduces briefly the causes of the great migration and the conditions of immigrants in the US. Then the focus moves on the analysis of the main themes that belong to the genre of Italian American literature. After having shortly treated the biography of Helen Barolini and a general presentation of her novel Umbertina, the essay goes on with the description of its three Italian American female characters and, in particular, of what it meant to be both immigrants and women, together with all the interior and generational conflicts they had to face in order to accept their new hybrid identity. An analysis of some meaningful metaphorical objects in the novel, such as the tin heart and the bedspread, the metaphor of Persephone and of the threshold conclude the essay. Through the analysis of the story of Umbertina, this essay wants to show how migration can lead to a displacement and the kind of journey people had to undertake in order to overcome the conflicts deriving from their belonging to an in-between culture and to accept their hybrid identity.

Orfeo aparece en múltiples fuentes como fundador de las teletai, esto es, del tipo de ritos a los que pertenecen claramente los Eleusinios, y como autor de poesía religiosa relacionada con ellos. Sin embargo, nadie a´Çü rma que los Misterios Eleusinos sean "ór´Çücos". Por otra parte, varias fuentes consideran a Eumolpo el fundador de los ritos. El artículo trata de explicar esta contradicción. Para ello se examinan los testimonios que relacionan a Orfeo con Eleusis o las teletai en general y los restos de la poesía ór´Çü ca sobre Deméter y Perséfone. Puede concluirse que había dos puntos de vista que coexistían sin solaparse: desde el punto de vista Eleusinio, Eumolpo aparece destacado y los Eumólpidas tienen el privilegio exclusivo de ser hierofantes. Desde el punto de vista ateniense, el prestigio de Orfeo es más "internacional" y sirve mucho mejor sus intereses políticos.

Predictive models of peptide-Major Histocompatibility Complex (MHC) binding affinity are important components of modern computational immunovaccinology. Here, we describe the development and deployment of a reliable peptide-binding prediction method for a previously poorly-characterized human MHC class I allele, HLA-Cw*0102.

CD8+ cytotoxic T lymphocytes (CTLs) play an important role in containment of virus replication in primary human immunodeficiency virus (HIV) infection. HIV's ability to mutate to escape from CTL pressure is increasingly recognized; but comprehensive studies of escape from the CD8 T cell response in primary HIV infection are currently lacking. Here, we have fully characterized the primary CTL response to autologous virus Env, Gag, and Tat proteins in three patients, and investigated the extent, kinetics, and mechanisms of viral escape from epitope-specific components of the response. In all three individuals, we observed variation beginning within weeks of infection at epitope-containing sites in the viral quasispecies, which conferred escape by mechanisms including altered peptide presentation/recognition and altered antigen processing. The number of epitope-containing regions exhibiting evidence of early CTL escape ranged from 1 out of 21 in a subject who controlled viral replication effectively to 5 out of 7 in a subject who did not. Evaluation of the extent and kinetics of HIV-1 escape from >40 different epitope-specific CD8 T cell responses enabled analysis of factors determining escape and suggested that escape is restricted by costs to intrinsic viral fitness and by broad, codominant distribution of CTL-mediated pressure on viral replication.
