ABSTRACT The investigation aims to analyze the technical viability of addition the waste from the filter-press from the mineral coal treatment process (TFP) and bottom ash from a thermoelectric (CP), in ceramic paste on the laboratory scale. Physical-chemical characterization and waste classification tests were carried out. Subsequently, ten formulations were developed through the mixture design (DoE), incorporating these residues into a standard clay ceramic paste (STD). The samples were formed by extrusion without vacuum and subjected to heat treatment in an oven and fired in a muffle at 900 °C. The evaluated technological properties were: shrinkage of drying and firing, water absorption and mechanical resistance and, finally, efflorescence tests and phytotoxicological analysis were performed. The results of solid waste classification, indicated these as not being dangerous (Class II-B - inert). The technical analysis of the samples show that compared to the clay ceramic standard formulation (STD), the other mixtures obtained results within the technical parameters, which can later be carried out in an industrial scale test. Although the mechanical tests with waste incorporation were below the standard formulation (STD), a test on an industrial scale is not discarded. In the efflorescence test, it was observed that there was no presence of soluble salts. And finally, in the phyto-toxicological test, with Allium cepa L. of a formulation with aggregation of all raw materials, it presented a result marginally similar to the standard, proving itself capable of reproduction on an industrial scale.

RESUMO A investigação teve por objetivo analisar a viabilidade técnica de incorporação do resíduo proveniente do filtro prensa do processo de beneficiamento do carvão mineral (TFP) e de cinzas pesadas (CP) advindos de uma termoelétrica, em massa cerâmica na escala laboratorial. Foram realizados ensaios de caracterização físico-química e de classificação dos resíduos. Posteriormente foram desenvolvidas dez formulações através de planejamento experimental por delineamento de misturas simplex centroide, incorporando esses resíduos a uma massa padrão de cerâmica vermelha. Os corpos-de-prova foram conformados por extrusão sem vácuo e submetidos a tratamento térmico em estufa e queima em forno mufla a 900 °C. As propriedades tecnológicas avaliadas foram: retração térmica linear de secagem e de queima, absorção de água e resistência mecânica à compressão e por fim, foram realizados testes de eflorescência e análise fitotoxicológica. Os resultados de classificação dos resíduos, indicaram esses como não sendo perigoso – Classe II-B – inerte. Os testes físicos dos corpos-de-prova mostram que comparados a formulação base de cerâmica vermelha (STD), as demais formulações obtiveram resultados dentro dos parâmetros técnicos, que podem ser posteriormente realizados em um ensaio de escala industrial. Embora os ensaios mecânicos das provas com incorporação de resíduo ficaram abaixo da formulação base (STD), não se descarta uma prova em escala similar a industrial. No ensaio de eflorescência, observou-se que não houve presença de sais solúveis. E por fim, no ensaio fitotoxicológico, com Allium cepa L. de uma formulação com agregação de todas matérias-primas juntas, apresentou um resultado próximos ao padrão, se mostrando apto a reprodução em escala industrial.

ABSTRACT Histoplasmosis is a systemic mycosis prevalent in the Americas. Humans become infected via the respiratory route by inhaling aerosols from soil contaminated with bird and bat excretions. Acute pulmonary histoplasmosis is usually asymptomatic and is more often a self-limiting illness. We report a series of seven acute pulmonary cases in adults during an outbreak in Nova Friburgo city, Rio de Janeiro State, Brazil, in a group of volunteers who were cleaning an old, abandoned house without using personal protective equipment. The patients had a favorable evolution after suitable treatment, but all required hospitalization.

ABSTRACT. The aim of this study was to evaluate the inclusion of 50% broken rice (BR) in diets for meat quail from 1 to 35 days old, starting at different ages. A total of 875 mixed quail were allocated to five treatments in a completely randomized design with five replicates of 35 birds. The treatments consisted of a maize- and soybean meal-based control diet and four other similar diets in which the inclusion of 50% BR was started at different ages, namely, 1st, 8th, 15th and 22nd days. Feed intake, weight gain, feed conversion and mortality rate were evaluated weekly. At 35 days, 10 quail per plot were weighed and selected to be slaughtered for evaluations of live weight, carcass yield and gizzard yield. Lastly, a study of economic viability was carried out. No significant difference (p > 0.05) was detected for the performance parameters, live weight or carcass yield, but a higher gizzard yield was found (p < 0.05) in the treatment without BR. The inclusion of BR from the first day of life provided better economic viability. Diets with a maximum inclusion of 50% BR can be formulated for meat quail at any age.

Obesity is a chronic inflammatory disease that affects millions of people worldwide. Most studies observe the effects of a high-fat diet (HFD) in 10-12 weeks. This work investigated the effects induced by a HFD administered for 6 weeks on the nutritional status of mice and some aspects of the inflammatory response in mouse peritoneal macrophages. Male Swiss Webster mice, 2-3 months of age, were fed a control diet or HFD for 6 weeks. After this period, the mice were euthanized, and peritoneal macrophages were collected for immunoassays and assessment of biochemical parameters. A HFD was associated with increased cholesterol, insulin resistance, C-reactive protein (CRP), leptin, and serum resistin levels. Lipopolysaccharide (LPS)- stimulated adipocyte cultures of animals subjected to a HFD showed increased production of proinflammatory cytokines such as tumor necrosis factor alpha (TNF-α), interleukin-1 (IL-1), and interleukin-6 (IL-6). However, peritoneal macrophages of the HFD group showed no changes in the levels of these cytokines. LPS-stimulated peritoneal macrophages from HFD-treated animals showed a reduction in mRNA expression of TNF-α and IL-6, as well as a decrease in expression of the transcription factor nuclear factor-kappa B (NF-kB). In conclusion, HFD treatment for 6 weeks induces similar signs to metabolic syndrome and decreases the capacity of peritoneal macrophages to develop an appropriate inflammatory response to a bacterial component.

ABSTRACT Clozapine is an antipsychotic that produces serious withdrawal effects in schizophrenic patients. Olfactory deficits are well known as part of negative symptoms, but it is not known whether antipsychotic use and/or withdrawal are implicated. Then, we tested clozapine withdrawal in association with two widely used schizophrenia models: Neonatal immune challenge by Polycitidilic-polyinosinic acid (polyI:C) and ketamine. PolyI:C (or saline) was injected subcutaneously in neonatal period, dose of 5 mg/kg from 2 to 6 Post Natal Days, and ketamine or saline at the dose 25mg/kg intraperitoneally (i.p.), daily for 7 days from 53 to 60 post natal day. Clozapine 10mg/kg (or saline) was administered i.p. from 46 to 60 post natal day. Olfactory discrimination test (sensorial and cognitive deficit) was performed at 61 post natal day, 24h after the last injections. The association of PolyI:C, ketamine and clozapine disrupted Olfactory Discrimination, equating time in familiar and non-familiar compartments. PolyI:C plus ketamine increased crossings between compartments. It was produced, for the first time, an olfactory deficit induced by clozapine withdrawal in Wistar rats subjected to schizophrenia animal models.

ABSTRACT The objective of this study was to identify eucalyptus clones for the production of sawed timber based on dendrometric variables and longitudinal residual deformation (LRD), analyzing the correlation between these characteristics. 20 Eucalyptus grandis x Eucalyptus urophylla clones with 13 years of age were analyzed. The crown size, diameter at breast height (DBH) and bark thickness were measured. There was a significant difference between the clones for DBH, LRD and bark thickness. There was no significant correlation between DBH and DRL. The correlation was significant between DBH and crown size, its being possible to affirm that crown size affects the diametrical growth of trees. DBH and bark thickness were also significantly correlated, in so far as trees with a wider diameter possess thicker bark. It was possible to select clones with better potential for sawed timber production, that is to say, elevated DBH with a reduced LRD.

PURPOSE: To investigate the effect of vibration therapy on the bone callus of fractured femurs and the bone quality of intact femurs in ovariectomized rats. METHODS: Fifty-six rats aged seven weeks were divided into four groups: control with femoral fracture (CON, n=14), ovariectomized with femoral fracture (OVX, n=14), control with femoral fracture plus vibration therapy (CON+VT, n=14), and ovariectomized with femoral fracture plus vibration therapy (OVX+VT, n=14). Three months after ovariectomy or sham surgery, a complete fracture was produced at the femoral mid-diaphysis and stabilized with a 1-mm-diameter intramedullary Kirschner wire. X-rays confirmed the fracture alignment and fixation. Three days later, the VT groups underwent vibration therapy (1 mm, 60 Hz for 20 minutes, three times per week for 14 or 28 days). The bone and callus quality were assessed by densitometry, three-dimensional microstructure, and mechanical test. RESULTS : Ovariectomized rats exhibited a substantial loss of bone mass and severe impairment in bone microarchitecture, both in the non-fractured femur and the bone callus. Whole-body vibration therapy exerted an important role in ameliorating the bone and fracture callus parameters in the osteoporotic bone. CONCLUSION: Vibration therapy improved bone quality and the quality of the fracture bone callus in ovariectomized rats.

Este estudo avaliou a difusão de íons hidroxila de diferentes pastas de hidróxido de cálcio contendo Aloe vera através dos túbulos dentinários. Foram utilizados 60 dentes bovinos unirradiculares. As coroas dos dentes foram removidas, os canais radiculares foram instrumentados e divididos em 4 grupos (n=15) de acordo com a medicação intracanal: Grupo HC/SF - pasta de hidróxido de cálcio e soro fisiológico; Grupo HC/P - pasta de hidróxido de cálcio e propilenoglicol; Grupo HC/A - pasta de hidróxido de cálcio e Aloe vera gel; Grupo HC/A/P - pasta de hidróxido de cálcio, propilenoglicol e Aloe vera. Após o preenchimento dos canais radiculares com as respectivas pastas, os dentes foram selados coronalmente e na região do ápice radicular com adesivo epóxi. Os dentes foram colocados em frascos identificados contendo água deionizada e armazenados em estufa, com 100% de umidade, a 37°C. Após 3h, 24h, 72h, 7 dias, 15 dias e 30 dias, a água deionizada dos frascos foi coletada e realizada a medição do pH com auxílio de um pHmetro. Os dados obtidos foram submetidos à análise estatística, com grau de significância de 5%. Os resultados mostraram que todas as pastas estudadas promoveram a difusão dos íons hidroxila através dos túbulos dentinários. A associação do Aloe vera ao HC (grupo HC/A) resultou em uma liberação de forma constante de íons cálcio. O grupo HC/A/P mostrou o pH mais elevado que as demais pastas em 24 e 72 horas. Concluiu-se que as pastas experimentais contendo Aloe vera foram capazes de permitir a difusão de íons hidroxila através dos túbulos dentinários.

This study evaluated the diffusion through the dentinal tubules of hydroxyl ions from different calcium hydroxide (CH) pastes containing Aloe vera. Sixty single-rooted bovine teeth were used. The tooth crowns were removed, the root canals were instrumented and the specimens were assigned to 4 groups (n=15) according to the intracanal medication: Group CH/S - CH powder and saline paste; Group CH/P - CH powder and propylene glycol paste; Group CH/A - calcium hydroxide powder and Aloe vera gel paste; Group CH/A/P - CH powder, Aloe vera powder and propylene glycol paste. After placement of the root canal dressings, the teeth were sealed coronally and apically with a two-step epoxy adhesive. The teeth were placed in identified flasks containing deionized water and stored in an oven with 100% humidity at 37 °C. After 3 h, 24 h, 72 h, 7 days, 15 days and 30 days, the deionized water in the flasks was collected and its pH was measured by a pH meter. The obtained data were subjected to statistical analysis at a significance level of 5%. The results demonstrated that all pastes provided diffusion of hydroxyl ions through the dentinal tubules. The combination of Aloe vera and CH (group CH/A) provided a constant release of calcium ions. Group CH/A/P showed the highest pH at 24 and 72 h. In conclusion, the experimental pastes containing Aloe vera were able to enable the diffusion of hydroxyl ions through the dentinal tubules.

Objetivo : Determinar a prevalência de doenças sexualmente transmissíveis em mulheres atletas. Métodos : Estudo observacional, de corte transversal, que incluiu 50 mulheres atletas com idade média de 20±3 anos. Realizaram-se colposcopia, coleta de colpocitologia oncótica cérvico-vaginal e pesquisa para Chlamydia trachomatis, papilomavírus humano e Neisseria gonorrhoeae, pelo método do reação de cadeia de polimerase. Amostras de sangue foram obtidas para pesquisa de vírus da imunodeficiência humana, sífilis, hepatite B e C. As atletas que apresentaram doenças clínicas ou laboratorialmente identificáveis receberam tratamento e acompanhamento no serviço. Resultados : Dentre as participantes, 46% relataram desconhecimento acerca das doenças sexualmente transmissíveis. A frequência de doenças sexualmente transmissíveis nas atletas foi de 48% (24 casos). Isoladamente, o papilomavírus humano foi o agente mais frequente (44%). Considerando o tipo de genótipo do papilomavírus humano, o subtipo 16 foi o mais prevalente (53%), seguido do 6-11 (22%) e do 18 (13%). Duas atletas tiveram resultado positivo para C. trachomatis. Não foi diagnosticado nenhum caso de infecção por N. gonorrhoeae, sífilis, hepatite B, hepatite C e vírus da imunodeficiência humana. Contudo, somente 26 atletas haviam sido vacinadas para hepatite B. Conclusão : A prevalência de doenças sexualmente transmissíveis em mulheres atletas foi elevada. Medidas de prevenção primária (vacinação para hepatite B e papilomavírus humano) e secundária (sorologias e colpocitologia) devem ser fornecidas a esse grupo específico de mulheres. O assunto deve ser abordado no meio desportivo.

Objective : To determine the prevalence of sexually transmitted diseases in female athletes. Methods : An observational, cross-sectional study was conducted including 50 female athletes with mean age of 20±3 years. Colposcopy, pap smear, and polymerase chain reaction for Chlamydia trachomatis, human papillomavirus and Neisseria gonorrhoeae were performed. Blood samples were collected to test for the human immunodeficiency virus, syphilis, hepatitis B and C. The athletes presenting clinical diseases or conditions identifiable by laboratory tests were treated and followed up in the unit. Results : Forty-six percent of the participants were unaware of sexually transmitted diseases. The prevalence of sexually transmitted diseases among athletes was 48% (24 cases). Human papillomavirus was the most frequent agent (44%). Considering the human papillomavirus genotypes, subtype 16 was the most prevalent (53%), followed by 11-6 (22%) and 18 (13%). Two athletes tested positive for C. trachomatis. There were no cases diagnosed of infection by N. gonorrhoeae, syphilis, hepatitis B, hepatitis C and human immunodeficiency virus. However, only 26 athletes had been vaccinated for hepatitis B. Conclusion : The prevalence of sexually transmitted diseases in female athletes was high. Primary prevention measures (hepatitis B and human papillomavirus vaccination) and secondary (serology, pap smears) must be offered to this specific group of women. The matter should be further approached in sports.

RESUMO O objetivo deste trabalho foi analisar o desempenho operacional do desdobro de Eucalyptus grandis W.Hill ex Maiden com motosserra, no contexto da utilização em pequena escala, utilizando-se como ferramentas de avaliação operacional do desdobro com motosserra foi satisfatório, com rendimento e eficiência operacional médios de 58,5% e diamétricas: 20,0-25,9 cm, 26,0-28,9 cm, 29,0-31,9 cm, 32,0-34,9 cm e 35,0-41,0 cm. O desempenho operacional do desdobro com motosserra foi satisfatório, com rendimento e eficiência médios de 58,5% e 0,55 m³/operário/h, respectivamente. No entanto, a viabilidade dessa técnica está restrita a sua utilização em pequena escala e ao padrão de qualidade exigido, da maneira como tem sido utilizada atualmente por pequenos produtores rurais. A classe diamétrica 3 (29,0-31,9 cm) apresentou o melhor rendimento, de 66,6%, pois foi aquela em que houve a melhor adequação do modelo de corte, ou seja, melhor relação entre diâmetro das toras e produtos gerados. Sugere-se para pesquisas futuras o desenvolvimento de modelos de corte específicos para cada classe diamétrica, além da redução da amplitude das classes, visando-se aumentar o rendimento em madeira serrada. De modo geral, o aumento do diâmetro das toras resulta em aumento da eficiência operacional. O tempo médio gasto por operação foi o mesmo para as classes 3, 4 e 5, demonstrando que a última apresentou a melhor eficiência operacional (0,82 m³/operador/h.).

ABSTRACT The aim of this work was to analyze the operational performance of Eucalyptus grandis W.Hill ex Maiden logs breakdown with chainsaw, taking into account small scale use, e.g., in small farms, using yield and operational efficiency as evaluation tools. The specific aim was to analyze the behavior of yield and operational efficiency in five diametric classes: 20.0-25.9cm, 26.0-28.9 cm, 29.0-31.9 cm, 32.0-34.9 cm and 35.0-41.0 cm. According to the results obtained, the chainsaw log breakdown had a satisfactory operational behavior, with average yield and operational efficiency of 58,5% and 0.55 m³/operator/h, respectively. However, the feasibility of such technique is restricted to small scale use. Diametric class 3 (29.0-31.9 cm) presented the best yield (66.6%) because it was the one that presented the best adequacy between log diameter and products. It is suggested for further researches the development of specific sawing patterns by diametric class, in addition to the reduction of class ranges, aiming the yield increase. The average breakdown time spent by log was the same for classes 3, 4 and 5, resulting that the latter presented the best operational efficiency (0.82 m³/operator/h).
