EMPREGO DA SERAPILHEIRA EM COPRODUTOS DE MINERAÇÃO E CRESCIMENTO INICIAL DA CATINGUEIRA (Poincianella pyramidalis (Tul.) LP Queiroz)

The mining activity causes several impacts on nature and one of the main mining activities carried out in the state of Paraíba and the extraction of vermiculite that generates a large amount of vermiculite co-product. The objective of this work was to evaluate the contribution of the Caatinga litter in the initial growth of catingueira in coproducts of the mining. The work was carried out in the Forest Nursery of the Forestry Engineering academic unit of the Federal University of Campina Grande. The treatments consisted of 5 doses of litter (0, 5, 10, 20 and 40%), added to a vermiculite co-product, and sowing of catingueira. Each treatment consisted of 3 replications totaling 15 plots. The analyzed variables were height, number of leaves and diameter collected 60 days after emergence. The parameters evaluated were root dry mass (MSR), dry shoot mass (MSPA), total dry mass (MST). It was observed that in the parameters, dry mass of the aerial part, dry mass of the root and total dry mass there was a positive linear relation (p <0,05).La actividad minera causa diversos impactos en la naturaleza y una de las principales actividades de minería realizada en el estado de la paraíba y la extracción de vermiculita que genera una gran cantidad de coproducto de vermiculita.

Presence of antibodies against Leishmania chagasi in haemodialysed patients

SOUZA,Roberto Mascarenhas et al.Presence of antibodies against Leishmania chagasi in haemodialysed patients.Transactions of the Royal Society of Tropical Medicine and Hygiene,v. 103, p.749-751, 2009.In the last decades there has been an increase in cases of visceral leishmaniasis complicating the post-transplant phase, mainly following kidney transplantation. The aim of this study was to evaluate the reactivity of haemodialysed patients using IFAT. Blood samples of 310 individuals from Natal, RN, Brazil, were collected and analysed. Data regarding blood transfusion, cause of end-stage renal disease and duration of haemodialysis were also analysed. In total, 69 patients (22.3%) were positive by IFAT. This study suggests that antibody detection should be performed in this group of patients since they are possible candidates for kidney transplantatio

Entre silêncios, nódoas e cobiça: homossexualidades masculinas, dominação e transgressão em O Barão de Lavos, de Abel Botelho e Bom-Crioulo, de Adolfo Caminha

Along our study we discuss the construction of the protagonists of two narratives: O Barão de Lavos (1891), by the Portuguese writer Abel Botelho, and Bom-Crioulo (1895), by the Brazilian writer Adolfo Caminha. In both narratives, male homosexuality and hibridity are negatively portrayed through the naturalist perspective, being classified as abnormal and dangerous since they oppose the objectives of the civilizing project that would be implemented in Brazil and in Portugal. Thus, comparative readings of both novels allow us to recognize the way socially rejected masculinities as well as hybridity were integrated to the optic of colonial desire proposed by the civilizing project of the 19th century. In this way, in both narratives homosexuality appears attached to the (hybrid) baron of Lavos and to the (black) Bom Crioulo as marks of rejection and marginalization generally imputed to any sexuality or race opposed to the heterosexual model. Even the genetic formation of both characters made it impossible for them to participate of the future republican project desired by Portugal and Brazil. The very negative markers that were imputed on these two literary figures because of social, cultural and political reasons, masqueraded as genetic heritage, were the reasons for the development of our alternative reading of these narratives, an analysis that used cultural studies and gender studies as its theoretical foundations. In respect to the heterocentrist and white model recognized in several naturalist narratives, which here aimed, through the voice of narrators, to identify the Baron and Bom-Crioulo as transgressors, in our study we indicate the possibility of diverse expressions of subjectivity, showing how different these can be from the narrow limits offered by the imposed hegemonic culture. This space for a different reading came through the oscillations and ambiguities present in voice of naturalist narrator.Coordenação de Aperfeiçoamento de Pessoal de Nível Superior - CAPESNeste trabalho discutimos como são moldados os protagonistas das narrativas O Barão de Lavos, do português Abel Botelho, e Bom-Crioulo, do brasileiro Adolfo Caminha. Nestas, as homossexualidades masculinas e a hibridização aparecem negativamente marcadas pelo olhar naturalista dos narradores, que as adjetivam de anormais e perigosas por serem antagônicas aos objetivos do processo civilizatório que deveriam ser implantados em Portugal e no Brasil do século XIX. Assim, a leitura dos respectivos romances pelo viés comparativo, permite que reconheçamos de que forma as masculinidades socialmente rejeitadas e a mistura racial estavam integradas à ótica do desejo colonial proposto. Deste modo, nas duas narrativas, as homossexualidades do híbrido Barão e do negro Bom-Crioulo, lhes são atribuídas como forma de rejeição e marginalização por serem manifestações contrárias à heterossexualidade compulsória. As respectivas formações genéticas destes personagens retiravam deles o direito de participar dos futuros projetos republicanos objetivados para Portugal e Brasil. Os marcadores negativos imputados a estas personagens literárias por questões sociais, culturais e políticas, mascaradas como herança genética, provocaram o desencadear de nossa análise, que se apoiou nos estudos culturais e de gênero. Assim, em relação ao reconhecido modelo heterocentrista e branco marcadamente presente nas narrativas naturalistas, que pretendeu, através de seus narradores, enquadrar o Barão e Bom- Crioulo como transgressores, indicamos em nosso estudo as diversas possibilidades de manifestação das subjetividades e como essas podem ir além das fronteiras da cultura imposta pela perspectiva do dominante, especificamente pela oscilação ou ambiguidade sempre possível na voz narrativa naturalista

Dengue Virus Serotype 2 Intrahost Diversity in Patients with Different Clinical Outcomes

Intrahost genetic diversity is thought to facilitate arbovirus adaptation to changing environments and hosts, and it might also be linked to viral pathogenesis. Dengue virus serotype 2 (DENV-2) has circulated in Brazil since 1990 and is associated with severe disease and explosive outbreaks. Intending to shed light on the viral determinants for severe dengue pathogenesis, we sought to analyze the DENV-2 intrahost genetic diversity in 68 patient cases clinically classified as dengue fever (n = 31), dengue with warning signs (n = 19), and severe dengue (n = 18). Unlike previous DENV intrahost diversity studies whose approaches employed PCR, here we performed viral whole-genome deep sequencing from clinical samples with an amplicon-free approach, representing the real intrahost diversity scenario. Striking differences were detected in the viral population structure between the three clinical categories, which appear to be driven mainly by different infection times and selection pressures, rather than being linked with the clinical outcome itself. Diversity in the NS2B gene, however, showed to be constrained, irrespective of clinical outcome and infection time. Finally, 385 non-synonymous intrahost single-nucleotide variants located along the viral polyprotein, plus variants located in the untranslated regions, were consistently identified among the samples. Of them, 124 were exclusively or highly detected among cases with warning signs and among severe cases. However, there was no variant that by itself appeared to characterize the cases of greater severity, either due to its low intrahost frequency or the conservative effect on amino acid substitution. Although further studies are necessary to determine their real effect on viral proteins, this heightens the possibility of epistatic interactions. The present analysis represents an initial effort to correlate DENV-2 genetic diversity to its pathogenic potential and thus contribute to understanding the virus’s dynamics within its human host
