Concreto com utilização de agregado graúdo sintético produzido a partir da lama vermelha: estudos de dosagem, propriedades e microestrutura

Atualmente questões relacionadas à sustentabilidade tem ganhado destaque no cenário mundial nos mais variados setores da sociedade. Diversos pesquisadores (LIMA, 2006; HILDEBRANDO, 1998; SOUZA, J., 2010; ROSSI, 2009, etc.) têm tentado propor uma interação entre a indústria da construção civil e aquelas que desenvolvem atividades de beneficiamento e produção mineral, como por exemplo,as de beneficiamento de bauxita. Neste contexto, encontrar uma viabilidade para o aproveitamento de um resíduo gerado em grandes quantidades e sem nenhuma utilidade seria contribuir com a preservação do meio ambiente, na medida em que se reduziria o consumo de recursos provenientes de fontes naturais e aumentaria a oferta de insumos no mercado da construção. Neste trabalho será abordada a viabilidade de produção de um concreto, que apresente características que o torne próprio ao uso como insumo na indústria da construção civil, por meio da utilização de um agregado sintético obtido a partir da lama vermelha (resíduo do beneficiamento da bauxita). De acordo com o programa experimental executado, os agregados, bem como, os concretos produzidos tiveram suas propriedades analisadas, objetivando estudar o processo de produção e dosagem respectivamente. Nos agregados foram realizadas análises de: porosidade aparente, absorção de água, massa específica aparente e abrasão Los Ángeles e nos concretos, trabalhabilidade, massa específica no estado fresco e no endurecido, resistência à compressão axial, resistência à tração por compressão diametral, tração na flexão, absorção de água e módulo de elasticidade. Ressalta-se que foi dada significativa importância à zona de transição pasta/agregado, por meio de análise da microestrutura dos concretos produzidos. Análise esta realizada por meio dos ensaios de: Porosimetria por Intrusão de Mercúrio (PIM) e Microscopia Eletrônica de Varredura (MEV). Os resultados das análises dos agregados sintéticos e dos concretos produzidos apresentaram resultados satisfatórios, demonstrando que estes apresentam potencial para uso na indústria da construção civil.

Hemoglobin D-Punjab: origin, distribution and laboratory diagnosis

This review discusses hemoglobin D-Punjab, also known as hemoglobin D-Los Angeles, one of the most common hemoglobin variants worldwide. It is derived from a point mutation in the beta-globin gene (HBB: c.364G>C; rs33946267) prevalent in the Punjab region, Northwestern Indian. Hemoglobin D-Punjab can be inherited in heterozygosis with hemoglobin A causing no clinical or hematological alterations, or in homozygosis, the rarest form of inheritance, a condition that is commonly not related to clinical symptomatology. Moreover, this variant can exist in association with other hemoglobinopathies, such as thalassemias; the most noticeable clinical alterations occur when hemoglobin D-Punjab is associated to hemoglobin S. The clinical manifestations of this association can be similar to homozygosis for hemoglobin S. Although hemoglobin D-Punjab is a common variant globally with clinical importance especially in cases of double heterozygosis, hemoglobin S/D-Punjab is still understudied. In Brazil, for example, hemoglobin D-Punjab is the third most common hemoglobin variant. Thus, this paper summarizes information about the origin, geographic distribution, characterization and occurrence of hemoglobin D-Punjab haplotypes to try to improve our knowledge of this variant. Moreover, a list of the main techniques used in its identification is provided emphasizing the importance of complementary molecular analysis for accurate diagnosis.

Comparative analysis of the replication of bovine herpesvirus 1 (BHV1) and BHV5 in bovine derived-neuron-like cells

Members of the subfamily Alphaherpesvirinae use the epithelium of the upper respiratory and/or genital tract as preferential sites for primary replication. However, bovine herpesvirus 5 (BoHV5) is neurotropic and neuroinvasive and responsible for meningoencephalitis in cattle and in animal models. A related virus, BoHV1 has also been occasionally implicated in natural cases of neurological infection and disease in cattle. The aim of the present study was to assess the in vitro effects of BoHV1 and BoHV5 replication in neuron-like cells. Overall, cytopathic effects, consisting of floating rounded cells, giant cells and monolayer lysis, induced by both viruses at 48 h postinfection (p.i.) resulted in a loss of cell viability and high virus titres (r = 0.978). The BoHV1 Cooper strain produced the lowest titres in neuron-like cells, although viral DNA was detected in infected cells during all experiments. Virus replication in infected cells was demonstrated by immunocytochemistry, flow cytometry and qPCR assays. BoHV antigens were better visualized at 48 h p.i. and flow cytometry analysis showed that SV56/90 and Los Angeles antigens were present at higher levels. In spite of the fact that BoHV titres dropped at 48 h p.i, viral DNA remained detectable until 120 h p.i. Sensitive TUNEL (terminal deoxynucleotidyltransferase-mediated dUTP-biotin nick end labeling) and annexin V assays were used to identify apoptosis. BoHV5 induced death in approximately 50 % of cells within 24 h p.i., similar to what has been observed for BoHV1 Los Angeles. Infection with the BoHV1 Cooper strain resulted in 26.37 % of cells being in the early stages of apoptosis; 63.69 % of infected cells were considered viable. Modulation of mitochondrial function, as measured by mitochondrial membrane depolarization, was synchronous with the virus replication cycle, cell viability and virus titres at 48 h p.i. Our results indicate that apoptosis plays an important role in preventing neuronal death and provides a bovine-derived in vitro system to study herpesvirus-neuron interactions.

Respiratory syncytial virus (RSV) pneumonia in a southern muriqui (Brachyteles arachnoides)

Background An adult male Brachyteles arachanoides, kept in captivity since 1990, was found dead without apparent clinical evidence. Methods Necropsy report, histopathology, immunohistochemistry, and ultrastructural examination were conducted. Results Pulmonary syncytial cells were positive for respiratory syncytial virus (RSV), and ultrastructural examination revealed viral particles inside macrophages compatible with the Paramyxoviridae family. Conclusions Muriquis are susceptible to RSV pneumonia followed by respiratory distress syndrome and death.

Low levels of adherence with proton pump inhibitor therapy contribute to therapeutic failure in gastroesophageal reflux disease

To assess adherence to proton pump inhibitor (PPI) treatment and associated variables in patients with gastroesophageal reflux disease (GERD). Cross-sectional and prospective comprising 240 consecutive adult patients, diagnosed with GERD for whom continuous use of standard or double dose of omeprazole had been prescribed. Patients were ranked as ne-GERD (162: 67.5%) or e-GERD classified according to the Los Angeles classification as A (48:20.0%), B (21:8.6%), C (1:0.5%), D (1:0.5%), and Barrett's esophagus (7:2.9%). The Morisky questionnaire was applied to assess adherence to therapy and a GERD questionnaire to assess symptoms and their impact. Adherence was correlated with demographics, cotherapies, comorbidities, treatment duration, symptoms scores, endoscopic findings, and patient awareness of their disease. 126 patients (52.5%) exhibited high level of adherence and 114 (47.5%) low level. Youngers (P= 0.002) or married (O.R. 2.41, P= 0.03 vs. widowers) patients had lower levels of adherence; symptomatic patients exhibited lower adherence (P= 0.02). All other variables studied had no influence on adherence. Patients with GERD attending a tertiary referral hospital in Sao Paulo exhibited a high rate of low adherence to the prescribed PPI therapy that may play a role in the therapy failure. Age <60 years, marital status and being symptomatic were risk factors for low adherence.

Too Big to Ignore: Global Partnership on Small-Scale Fisheries Research - the Latin America and Caribbean network

Too Big to Ignore (TBTI; www.toobigtoignore.net) is a research network and knowledge mobilization partnership established to elevate the profile of small-scale fisheries (SSF), to argue against their marginalization in national and international policies, and to develop research and governance capacity to address global fisheries challenges. Network participants and partners are conducting global and comparative analyses, as well as in-depth studies of SSF in the context of local complexity and dynamics, along with a thorough examination of governance challenges, to encourage careful consideration of this sector in local, regional and global policy arenas. Comprising 15 partners and 62 researchers from 27 countries, TBTI conducts activities in five regions of the world. In Latin America and the Caribbean (LAC) region, we are taking a participative approach to investigate and promote stewardship and self-governance in SSF, seeking best practices and success stories that could be replicated elsewhere. As well, the region will focus to promote sustainable livelihoods of coastal communities. Key activities include workshops and stakeholder meetings, facilitation of policy dialogue and networking, as well as assessing local capacity needs and training. Currently, LAC members are putting together publications that examine key issues concerning SSF in the region and best practices, with a first focus on ecosystem stewardship. Other planned deliverables include comparative analysis, a regional profile on the top research issues on SSF, and a synthesis of SSF knowledge in LAC

Effect of photodynamic therapy with different formulations of methylene blue in teeth contaminated by Enterococcus faecalis

The aim of this study was to compare the disinfection of dentine using photodynamic therapy with methylene blue in different formulations. Thirty bovine teeth roots were autoclaved and incubated with a suspension of Enterococcus faecalis. The specimen were randomly divided into three groups: G1, the roots were filled with 10 mM methylene blue dissolved in water; G2, the roots were filled with 10 mM methylene blue dissolved in a mixture of glycerol: ethanol: water; G3, roots filled with 100 mM methylene blue dissolved in water. The groups were irradiated with a 660 nm diode laser with an output power of 100 mW for 4 min, energy density of 850 J/cm2 and after this procedure, the sensitizer was removed and microbial samples were collected from within the root canals. The samples were plated on mEnterococcus to count the colony-forming units (CFU/mL). The means were: Group 1=513×103, Group 2=1431×103 and Group 3=2.96×103. The statistical analysis detected higher disinfection achieved by G3 when compared with groups G1 and G2, and no significant difference between the groups G1 and G2 (P>0.05). The increase of the concentration of methylene blue dye achieved higher disinfection in photodynamic therapy.

Hydroxocobalamin quantification in human plasma by high-performance liquid chromatography coupled with electrospray tandem mass spectrometry in a pharmacokinetic study

A rapid, sensitive and specific method for quantifying hydroxocobalamin in human plasma using paracetamol as the internal standard (IS) is described. The analyte and the IS were extracted from plasma by liquid-liquid extraction using an organic solvent (ethanol 100%; -20°C). The extracts were analyzed by high performance liquid chromatography coupled with electrospray tandem mass spectrometry (HPLC-MS-MS). Chromatography was performed on Prevail C8 3 μm, analytical column (2.1×100 mm i.d.). The method had a chromatographic run time of 3.4 min and a linear calibration curve over the range 5-400 ng.mL-1 (r>0.9983). The limit of quantification was 5 ng.mL-1. The method was also validated without the use of the internal standard. The precision in the intra-batch validation with IS was 9.6%, 8.9%, 1.0% and 2.8% whereas without IS was 9.2%, 8.2%, 1.8% and 1.5% for 5, 15, 80 and 320 ng/mL, respectively. The accuracy in intra-batch validation with IS was 108.9%, 99.9%, 98.9% and 99.0% whereas without IS was 101.1%, 99.3%, 97.5% and 92.5% for 5, 15, 80 and 320 ng/mL, respectively. The precision in the inter-batch validation with IS was 9.4%, 6.9%, 4.6% and 5.5% whereas without IS was 10.9%, 6.4%, 5.0% and 6.2% for 5, 15, 80 and 320 ng/mL, respectively. The accuracy in inter-batch validation with IS was 101.9%, 104.1%, 103.2% and 99.7% whereas without IS was 94.4%, 101.2%, 101.6% and 96.0% for 5, 15, 80 and 320 ng/mL, respectively. This HPLC-MS-MS procedure was used to assess the pharmacokinetics of Hydroxo cobalamin following intramuscular injection 5000 μg in healthy volunteers of both sexes (10 males and 10 females). The volunteers had the following clinical characteristics (according to gender and expressed as mean ± SD [range]): males: age: 32.40 ± 8.00 y [23.00-46.00], height: 1.73 ± 0.07 m [1.62-1.85], body weight: 72.48 ± 10.22 Kg [60.20- 88.00]; females: age: 28.60 ± 9.54 y [18.00-44.00], height: 1.60 ± 0.05 m [1.54-1.70], body weight: 58.64 ± 6.09 Kg [51.70- 66.70]. The following pharmacokinetic parameters were obtained from the hydroxocobalamin plasma concentration vs. time curves: AUClast, T1/2, Tmax, Vd, Cl, Cmax and Clast. The pharmacokinetic parameters were 120 (± 25) ng/mL for Cmax, 2044 (± 641) ng.h/mL for AUClast, 8 (± 3.2) ng.mL-1 for Clast, 38 (± 15.8) hr for T1/2 and 2.5 (range 1-6) hr for Tmax. Female volunteers presented significant (p=0.0136) lower AUC (1706 ± 704) ng.h/mL) and larger (p=0.0205) clearance (2.91 ± 1.41 L/hr), as compared to male 2383 ± 343 ng.h/mL and 1.76 ± 0.23 L/hr, respectively. These pharmacokinetic differences could explain the higher prevalence of vitamin B12 deficiency in female patients. The method described validated well without the use of the internal standard and this approach should be investigated in other HPLC-MS-MS methods.

El seudónimo masculino y la androginización de la mujer escritora

[ES] Mediante la adopción del seudónimo masculino, algunas escritoras del siglo XIX y de la primera mitad del XX pudieron introducirse en un ámbito controlado absolutamente por hombres: el de la literatura. La sustitución de su nombre legal por otro ficticio les permitió ganarse el respeto de un elevado porcentaje de lectores que se mostraban todavía reticentes a valorar positivamente las obras escritas por una mujer, consideradas frívolas, sensibleras e intrascendentes. La necesidad de llevar puesta una máscara para alcanzar semejantes objetivos demuestra, no obstante, que las autoras de entonces en cierto modo seguían sometidas a los dictámenes de la sociedad patriarcal, cuyos prejuicios hubieron de asumir si querían que sus textos vieran la luz y fuesen tomados en serio. Con el seudónimo varonil ‒unido ocasionalmente también al travestismo físico, como ejemplifica el caso de George Sand‒, las escritoras forjaron de sí mismas unas imágenes descentradas, ambiguas, andróginas. Al mismo tiempo, la estrategia del cambio de género autoral presuponía el reconocimiento de una «condición masculina» inherente a la escritura.
