It grows on foothill slopes, in <i>cerrado</i> vegetation (savanna) in reddish sandy soil. According to the IUCN Red List criterion B (IUCN 2012, 2019), <i>Lychnophora goiana</i> can be considered Critically Endangered (CR), since it is known from a single location. In addition, the sandy soil, very susceptible to erosion, and the proximity to agricultural lands considerably increase the threat of extinction for this species.</p> <p> <b>Etymology:</b> —The species epithet refers to the state of Goiás, where this new species is endemic. We maintain the same epithet originally chosen by Semir (1991), although this species is likely to also occur in the state of Bahia, as it was found near the border of these two states.</p> <p> <b>Additional specimens examined (paratypes):</b> — BRAZIL.

It is the fourth species of this complex, which also contains <i>L. granmogolensis</i>, <i>L. nanuzae</i> Semir in Semir <i>et al.</i> (2014: 989) and <i>L. rupestris</i> Semir in Semir <i>et al.</i> (2014: 988). <i>Lychnophora goiana</i> differs from the other three species by its outer pappus series as long as the cypsela, sometimes even longer, with the upper part of the setae frequently twisted. It is similar to <i>L. rupestris</i> by its leaf insertions with a sparse tuft of small trichomes, midrib winged and flattened on the abaxial surface, but differs by the never glaucous leaves with adaxially impressed midrib (vs. frequently glaucous and carinate midrib) and obscurely costate cypsela (vs. conspicuously). <i>Lychnophora goiana</i> shares with <i>L. granmogolensis</i> the leaves with adaxially impressed midvein, but the latter has leaf insertion with a dense tuft of long trichomes, adaxially glabrescent midvein (vs. glabrate), abaxially rounded midvein and conspicuously costate cypsela. <i>Lychnophora nanuzae</i> is easily distinguishable from the new species by the leaves with revolute margins touching each other abaxially, forming flattened cylinders (vs. margins not touching), rounded leaf base (vs. cordate to auriculate) and heads with three florets (vs. one) (Table 2). Each species of the complex has a distinct distribution: <i>L. rupestris</i> is endemic to Serra do Cipó (state of Minas Gerais), <i>L. nanuzae</i> to Diamantina Plateau and Itacambira (state of Minas Gerais), <i>L. granmogolensis</i> occurs from Diamantina Plateau to Chapada Diamantina in the state of Bahia. All these localities are in the Espinhaço mountain range, whereas <i>L. goiana</i> is restricted to Serra Geral de Goiás (state of Goiás), a mountain range that divides two major river basins, the São Francisco and Tocantins rivers (Fig. 6) (Semir 1991, Semir <i>et al.</i> 2014, Loeuille <i>et al.</i> 2019).</p>Published as part of <i>Loeuille, Benoît, Bringel Jr, João Bernardo De A., Faria Jr, Jair E.

The APAGCV links continuous protected areas that differ in management regulations and governmental institution in charge but share the conservation purpose (UNESCO 2003). Nevertheless, these protected areas are surrounded by urban occupation, which can affect environmental quality (UNESCO 2003, Aguiar 2015). There are two locations of occurrence of <i>L. planaltina</i>, with the first collection dating to more than 40 years ago (1968), made in a farm that belongs to the local public university (FAL - Fazenda Água Limpa, Universidade de Brasília); ca. 22.09 km 2 of the 42.31 km 2 of the farm are determined as environmental protection area by the Brazilian law (Aguiar 2015) (Fig. 9). Although more than half of the area of the farm is destined to environmental conservation, we cannot verify that this population is still preserved due to the lack of a precise description of the collection location in the label of this first <i>L. planaltina</i> specimen.</p> <p> The most recent collections are from one single location in the Jardim Botânico de Brasília (Brasília Botanic Garden) ecological station (Estação Ecológica Jardim Botânico de Brasília - EEJBB), which shares a boundary with FAL. Less than five individuals were found in this second location.Although we could not precisely calculate the EOO and AOO for <i>L. planaltina</i>, we believe it has an extremely reduced population, covering a very restricted area, which is surrounded by the urban occupation of Brasília. Therefore, we considered it Critically Endangered.</p> <p> <b>Etymology:</b> —The species epithet refers to the geographic distribution, as in Portuguese <i>planaltina</i> means that who inhabits the Brazilian Central Plateau.</p> <p> <b>Additional specimens examined (paratypes):</b> — BRAZIL.

A.</i> <i>Soares</i> 10169 (UB).</p> <p> <b>Discussion:</b> — <i>Lychnophora planaltina</i> is morphologically closely related to <i>L. crispa</i> Mattfeld (1923: 429) by its adaxially bullate leaves with an inconspicuous mucro, and cylindrical involucre with deciduous weakly imbricate phyllaries. However, it differs from the latter by its glaucous, linear, very narrow elliptic, or rarely lanceolate leaves (vs. greenish, ovate to lanceolate), solitary syncephalium (vs. subcorymb, rarely solitary) and sparsely sericeous cypsela (vs. glabrous). The two species do not occur in sympatry: <i>L. crispa</i> is found in the Espinhaço mountain range in the states of Bahia (Chapada Diamantina) and northern Minas Gerais, whereas <i>L. planaltina</i> is restricted to the Brasília area in the Distrito Federal.An interesting feature of <i>L. planaltina</i> is the cypselae connated in pairs in some individuals, a phenomenon that has been observed in <i>L. pinaster</i> Martius (1822: 152) and <i>Lychnocephalus jolyanus</i> Semir ex Gomes & Loeuille (2021: 483).</p> <p> The <i>Lychnophora planaltina</i> specimen cited above, <i>Menezes 2</i> (SP108141), was included in a study of the leaf anatomy of several Asteraceae from campos rupestres (Handro <i>et al.</i> 1970), but was then identified as <i>L. reticulata</i> Gardner (1846: 233) [= <i>Eremanthus reticulatus</i> (Gardner) Loeuille <i>et al.</i> (2019: 43)]. This is the same specimen that João Semir described in his unpublished Ph.D. thesis (Semir 1991), in which he placed <i>L. planaltina</i> in a species complex with <i>L. crispa</i> and <i>L. reticulata</i>, but a phylogenetic analysis of Lychnophorinae (Loeuille <i>et al.</i> 2015) showed that <i>L. reticulata</i> belongs to the genus <i>Eremanthus</i> and not in <i>Lychnophora.</i></p>Published as part of <i>Loeuille, Benoît, Bringel Jr, João Bernardo De A., Faria Jr, Jair E.

Pappus coroniform, apex laciniate, pale yellow, 0.2–0.4 mm long, hispidulous. Fig. 3. Comments:—Although a description of Wedelia monantha was absent from the first edition of FF of 1829, published only in 1881, its plate was published in 1831. That plate includes elements that may be clearly recognized as analysis, according the ICN Art. 38.7, 38.8 and 38.9 (Turland et al. 2018). The pistillate ray flowers, coroniform pappus, isolated heads with a long peduncle, together with the lanceolate, with distinct petiole are diagnostic for the species illustrated in the Aster monanthus plate. This species is currently treated as W. subvelutina by Alves & Bringel Jr. (2020). However, the older name, Aster monanthus, validly published in a plate from 1831, has priority over it. Another remarkable feature of W. monantha, and also of the majority of the other species of this genus, is the trinervate leaves. Although it is not possible to clearly recognize the trinervate leaves in the plate from Vellozo (1831), the pattern of venation drawn is similar to the pattern found in some specimens from Rio de Janeiro (Glaziou 5615, Warming 663) and Minas Gerais (Nunes 186), in which the perimarginal veins are not as thick as the primary one, rather a slight perimarginal vein can be recognized, resembling a brochidodromous pattern. We believe that the age of the leaf and habitat conditions are responsible for this variation. Vellozo (1881) described the original habitat of A. monanthus as “ habitat campis apricis mediterraneis transalpinis ”, interpreted by Pastore et al. (2021) as originated in the municipality of Cunha (São Paulo state). Since the original specimens are considered lost (Carauta 1973; Bediaga & Lima 2015; Pastore et al. 2021), the only set of original material is the plates preserved in the National Archive of Torre do Tombo (Lisbon) and the National Library of Brazil (Rio de Janeiro) Biblioteca Nacional (Rio de Janeiro). Therefore, an epitype has been accordingly designated on the basis of a modern specimen collected along the Estrada Real in Cunha. Although the illustration of Aster monanthus is sufficient for identification of the species by specialists, the illustrations in the Flora Fluminensis cannot be considered complete in all of the species representative features. Therefore an epitype was assigned based on a modern specimen collected along the Estrada Real in Cunha in order to provide a full detailed specimen, and so, accurately supporting application of the name according to Art. 9.9 (Turland et al. 2018). Habitat, distribution and phenology: — Wedelia monantha occurs for the most part in the Atlantic Forest domain, but also in the ecotone regions with patches of the savanna vegetation (cerrado sensu lato). It is usually found on the margin of forests, more rarely in open marshy fields. The species occurs in the Brazilian states of Minas Gerais, Rio de Janeiro, São Paulo, and Paraná (Fig. 4) flowering from October to April. Curiously, in the Checklist of the Spermatophyta of the State of São Paulo no species of the genus Wedelia is mentioned (Wanderley et al. 2011).

No full textEste artículo se propone discutir las disputas de sentido por los imaginarios del desarrollo en América Latina a través de la tensión entre autonomía/emancipación y adhesión/adaptación al desarrollo capitalista. El objetivo es analizar cómo estos imaginarios son creados, resignificados y contestados en diferentes momentos históricos a partir de irrupciones teórico-discursivas, pero también práctico-políticas.Depto. de Relaciones Internacionales e Historia GlobalFac. de Ciencias Políticas y SociologíaTRUEpu
Prevalence of human papillomavirus in HIV positive patients and associated factors.
No full textO Papilomavírus Humano (HPV) é o agente etiológico de uma das mais frequentes doenças sexualmente transmissíveis, o qual vem apresentando crescente incidência na sociedade, sobretudo em pacientes infectados pelo Vírus da Imunodeficiência Humana (HIV). Por ser considerado um dos maiores cofatores do câncer do colo do útero, o HPV configura-se na atualidade como um importante problema de saúde pública. É urgente a necessidade de compreender a evolução, a prevenção e a detecção precoce do HPV e das suas lesões precursoras, bem como sua relação com o HIV. O objetivo geral deste trabalho foi avaliar a prevalência de infecção pelo HPV em mulheres HIV positivo. Trata-se de uma pesquisa de estudo transversal, realizada no Complexo Hospitalar Clementino Fraga (CHCF), no município de João Pessoa-PB, com amostra composta por 824 prontuários de mulheres com confirmação diagnóstica de infecção pelo HIV. Para a coleta de dados, utilizou-se um questionário para a obtenção dos dados sociodemográficos, comportamentais, imunológicos e terapêuticos relacionados à infecção pelo HIV e HPV. A análise de dados foi subsidiada pelos programas STATA e SPSS, com hipóteses testadas por meio do Qui-quadrado de Pearson e o Teste Exato de Fisher, sendo o p-valor considerado de 0,05 e a análise múltipla feita por meio de regressão de Poisson. Os resultados evidenciaram que 20,1% das mulheres HIV positivo, que foram ao ginecologista, apresentaram também a infecção pelo HPV. Na análise múltipla, observou-se associação positiva entre carga viral detectável e a infecção por HPV. As mulheres com carga viral detectável demonstram quase cinco vezes mais chance de ter HPV (95% de intervalo de confiança: 1,8;12,3) e razão de prevalência de 4,76. A elevada contagem de células CD4 foi identificada como fator de proteção para infecção na análise simples, com razão de prevalência de 0,54 (intervalo de confiança de 95%; 0,3; 0,9). O aumento do risco da população, aliado ao baixo conhecimento sobre o HIV e HPV, indica a necessidade de mais educação sobre essas DST, como também, necessita-se de estudos futuros que devem aprofundar o conhecimento dos diferentes perfis da coinfecção HIV-HPV em cenários de atenção às Infecções Sexualmente Transmissíveis.The Human Papillomavirus (HPV) is the etiological agent of one of the most frequent sexually transmissible diseases, which has been showing an increasing incidence in society, especially in patients infected with human immunodeficiency virus (HIV). Since it is considered one of the major co-factors of cervical cancer, HPV is nowadays an serious public health problem. There is an urgent need to understand the evolution, prevention and early detection of HPV and its precursor lesions, as well as its relationship with HIV. The aim of this study is to evaluate the prevalence of HPV infection in HIV positive women. This is a cross-sectional study carried out in the Clementino Fraga, Hospital Complex in the city of João Pessoa, with a sample composed of 824 medical records of women with diagnostic confirmation of HIV infection. In order to collect information, a questionnaire was used to obtain sociodemographic, behavioral, immunological and therapeutic data related to HIV and HPV infection. Data analysis was subsidized by the STATA and SPSS programs, with hypotheses tested using the Pearson's Chi-square and the Fisher's Exact Test, with a p-value of 0.05 and multiple analysis performed using Poisson regression. The results showed that 20.1% of HIV-positive women, who consulted a gynecologist, also had HPV infection. In the multiple analysis, a positive association between detectable viral load and HPV infection was observed. Women with detectable viral load demonstrate approximately five times more chances of having HPV (95% of de IC:1,8;12,3) and a reason prevalence of 4,7. The high of CD4 cell counts has been identified as a protective factor for infection in the simple analysis, with a reason prevalence of 0,54 (95% of IC:0,3;0,9). The increased risk of the population, coupled with low knowledge about HIV and HPV, indicates the need for more education about these STDs, as well as future studies that need to deepen the knowledge of the different profiles of HIV-HPV coinfection in scenarios of attention to Sexually Transmitted Infections
Competition between collective and non collective excitation modes at high spin in 124Ba
No full textHigh-spin states in124Ba were investigated in two experiments using the 64Ni(64Ni,4n)124Ba reaction at three different beam energies. In-beam γ-ray coincidences were measured with the Euroball and Gammasphere detector arrays. In the experiment with Euroball, the CsI detector array Diamant was employed to discriminate against charged-particle channels. Six new rotational bands were observed in 124Ba, and previously known bands were extended to higher spins. One of the bands shows a transition from collective to non collective behaviour at high spins. Configuration assignments are suggested on the basis of comparison with cranked shell model and cranked Nilsson-Strutinsky calculations
Re-Evaluation of Praxelis (Asteraceae, Eupatorieae) in Brazil and Description of Praxelis scaturicola, an Unusual Riverine Species
No full textPraxelis scaturicola, a new Cerrado biome species, is described and illustrated. The main morphological features of this new species are: i) capitula usually isolated; ii) vinaceous involucral bracts; iii) reduced glabrous leaves well-spaced on the stem. This study also presents informa-tion on aspects of the new species? habitat, as well as field images and illustrations. Praxelis scaturicola is known only from the Parauna municipality in Goias state, Brazil. A key and comments on the Brazilian species of Praxelis are also presented with a special note on the status of P. grandiflora.Additionally, the synonymy of P. macrocarpa under P. capillaris is proposed.Fil: Neves Ribeiro, Rogério.

Imaginarios sobre el desarrollo en América Latina: entre la emancipación y la adaptación al capitalismo
No full textAmérica Latina es autora de un prolífico pensamiento crítico sobre el desarrollo, que cuestiona las premisas de este concepto y reconoce la heterogeneidad y especificidades de la región. A lo largo del siglo XX, América Latina produjo interpretaciones originales como la Teoría de la Dependencia, que cayó en desuso en la "década perdida". No obstante, a pesar de las dificultades, tras los fracasos del neoliberalismo, el pensamiento crítico se revitalizó y dio lugar a propuestas heterogéneas que hoy contienden sus sentidos y significados, ofreciendo muchas veces alternativas para superar el sustrato capitalista y colonial del desarrollo. Este libro explora algunas de las contribuciones contemporáneas más importantes del pensamiento crítico latinoamericano sobre el desarrollo, como aquellas formuladas desde el postdesarrollo, el buen vivir, la crítica decolonial y el pensamiento feminista. A su vez, presenta la riqueza de las aportaciones formuladas desde la economía y la teoría del comercio internacional, la educación, los estudios migratorios, la ciencia y la tecnología, la salud y el medioambiente. La pluralidad de visiones reunidas y su enfoque innovador hacen de este libro una herramienta imprescindible para los estudios del desarrollo y las ciencias sociales en América Latina.Depto. de Relaciones Internacionales e Historia GlobalFac. de Ciencias Políticas y SociologíaTRUEpu
