Abstract Spinal muscular atrophy (SMA) is considered one of the most common autosomal recessive disorders, with an estimated incidence of 1 in 10,000 live births. Testing for SMA has been recommended for inclusion in neonatal screening (NBS) panels since there are several therapies available and there is evidence of greater efficacy when introduced in the pre/early symptomatic phases. In Brazil, the National Neonatal Screening Program tests for six diseases, with a new law issued in 2021 stating that it should incorporate more diseases, including SMA. In the present study, dried blood spot (DBS) samples collected by the Reference Services of Neonatal Screening of RS and SP, to perform the conventional test were also screened for SMA, using real-time PCR, with SALSA MC002 technique. A total of 40,000 samples were analyzed, enabling the identification of four positive cases of SMA, that were confirmed by MLPA. Considering our sampling, Brazil seems to have an incidence comparable to the described in other regions. This work demonstrated that the use of the MC002 technique in samples routinely collected for the conventional NBS program is suitable to screen for SMA in our conditions and can be included in the expansion of the neonatal screening programs.

Abstract This study estimated the potential effects of climate change on peripheral plant diversity by predicting the distribution of species from Cerrado of Northern Brazil. Ecological niche modeling was used to provide present and future projections of responses in terms of occurrence of ten woody species based on four algorithms and four future climate change scenarios for the year 2050. Potential refuge areas for conservation actions were identified, and evidence of the vulnerability of the flora was demonstrated based on the disparity between potential areas of climate stability amid current protected areas. The results suggested a lack of pattern between the scenarios and an idiosyncratic response of the species, indicating different impacts on plant communities and the existence of unequal stable alternative conditions, which could bring consequences to the ecological relationships and functionality of the floras. Even in the most pessimistic scenarios, most species presented an expansion of potential occurrence areas, suppressing or cohabiting with species of adjacent biomes. Typically marginal plants were the most sensitive. Overlapping adequate habitats are concentrated in the NBC. The analysis of habitats in relation to anthropized areas and PAs demonstrate low future effectiveness in the protection of these savannas.

Abstract Introduction: We investigated the clinical course and outcomes of patients submitted to cardiovascular surgery in Brazil and who had developed symptoms/signs of coronavirus disease 2019 (COVID-19) in the perioperative period. Methods: A retrospective multicenter study including 104 patients who were allocated in three groups according to time of positive real time reverse transcriptase-polymerase chain reaction (RT-PCR) for the SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2): group 1, patients who underwent cardiac surgery > 10 days after positive RT-PCR; group 2, patients with a positive RT-PCR within 10 days before or after surgery; group 3, patients who presented positive RT-PCR > 10 days after surgery. The primary outcome was mortality and secondary outcomes were postoperative complications, intensive care unit (ICU) length of stay, and postoperative days of hospitalization. Results: The three groups were similar with respect to age, the European System of Cardiac Operative Risk Evaluation score, and comorbidities, except hypertension. Postoperative complications and death were significantly higher in groups 2 and 3 than in group 1, and no significant difference between groups 2 and 3 was seen. Group 2 showed a high prevalence of surgery performed as an urgent procedure. Although no significant differences were observed in ICU length of stay, total postoperative hospitalization time was significantly higher in group 3 than in groups 1 and 2. Conclusion: COVID-19 affecting the postoperative period of patients who underwent cardiovascular surgery is associated with a higher rate of morbidity and mortality. Delaying procedures in RT-PCR-positive patients may help reduce risks of perioperative complications and death.

RESUMO INTRODUÇÃO: A tuberculose pulmonar causada por Mycobacterium tuberculosis é um grave problema de saúde pública que afeta mundialmente milhões de indivíduos. O desenvolvimento de métodos de diagnóstico fáceis e de baixo custo é essencial para o controle da doença nas áreas rurais remotas e de pobreza e entre os grupos vulneráveis. OBJETIVO: Avaliar a acurácia dos métodos laboratoriais para o diagnóstico de tuberculose pulmonar. MATERIAL E MÉTODOS: As amostras de escarro de pacientes com sinais e sintomas clínicos foram analisadas por microscopia após tratamento químico e sedimentação espontânea e comparadas com métodos empregados rotineiramente: baciloscopia direta do escarro, cultura e GeneXpert® MTB/RIF. RESULTADOS: Das amostras analisadas, 16% foram positivas por microscopia nas amostras processadas; 18%, por cultura e Xpert® MTB/RIF; e 13%, por microscopia direta. As amostras processadas apresentaram um aumento de 31% de positividade (57 amostras) em relação à microscopia direta convencional. Na análise dos métodos avaliados, todos os resultados foram estatisticamente significativos, comprovando que não eram positivos ou negativos aleatoriamente e confirmando que há uma tendência para esses resultados. CONCLUSÃO: O tratamento químico e a sedimentação espontânea das amostras de escarro representam uma ferramenta diagnóstica eficaz nas situações em que tecnologias mais avançadas não são viáveis. Além da maior precisão e maior detecção de casos positivos em relação ao esfregaço direto, o procedimento reforça a biossegurança, diminuindo os riscos de contaminação aérea por Mycobacterium tuberculosis para profissionais de laboratório

ABSTRACT INTRODUCTION: Pulmonary tuberculosis caused by Mycobacterium tuberculosis is a serious public health problem affecting millions of people worldwide. The development of easy and low-cost diagnostic methods is crucial for disease control in rural remote and poverty areas and among vulnerable groups. OBJECTIVE: To evaluate the accuracy of laboratory methods for the diagnosis of Pulmonary tuberculosis. MATERIAL AND METHODS: Sputum samples from patients with clinical signs and symptoms were analyzed by microscopy after chemical treatment and spontaneous sedimentation and compared with methods employed routinely: direct sputum smear microscopy, culture, and GeneXpert®MTB/RIF. RESULTS: From the samples analyzed, 16% were positive by microscopy in the processed samples, 18% by both culture and Xpert®MTB/RIF, while 13% in the direct microscopy. The processed samples showed a 31% increase in positivity (57 samples) compared to conventional direct microscopy. In the analysis of the accuracy of the evaluated methods, all the results were statistically significant proving that they were not randomly positive or negative and confirming that there is a tendency for these results. CONCLUSION: Chemical treatment and spontaneous sedimentation of the sputum samples procedure represent an effective diagnostic tool in situations where more advanced technologies are not feasible. Besides the higher accuracy and greater detection of positive cases regarding the direct smear, the procedure strengthens biosafety by decreasing the risks of aerial contamination by Mycobacterium tuberculosis for laboratory professionals.

Resumo Os produtores de calcário e cal inadvertidamente geram uma quantidade considerável de material fino durante o processamento, tornando-se um grande passivo ambiental. Quanto ao processo de calcinação, a indústria ressente-se de dados experimentais da lei de Arrhenius, como fator de frequência aparente e energia de ativação, referentes aos calcários brasileiros. O conhecimento desses parâmetros termocinéticos pode diminuir o consumo energético durante o processo de calcinação industrial, além de permitir o uso de finos de calcário em outras aplicações industriais. Este trabalho teve como objetivo caracterizar três calcários brasileiros, concentrando-se em sua calcinação em escala laboratorial, usando método quase isotérmico e dinâmico (termogravimétrico) para estimar seus parâmetros cinéticos. O método dinâmico permitiu estimar a energia de ativação de cada calcário através das regiões de alta taxa de calcinação. Porém, os parâmetros cinéticos estimados pelo método quase isotérmico resultaram em valores mais baixos, indicando a necessidade de controlar a atmosfera do reator.

Abstract Limestone and lime producers inadvertently generate a considerable amount of fine material during their processing, consequently becoming a great environmental liability. As far as the industrial calcination process is concerned, there is still a need for an experimental survey on Arrhenius law parameters, as apparent frequency factor and activation energy, referring to Brazilian limestones. The knowledge of these thermokinetic parameters may contribute to energy saving during the industrial calcination process, as well as for allowing the use of limestone fines in other industrial applications. This study aimed to characterize three Brazilian limestones by focusing on their laboratory-scale calcination using both quasi-isothermal and non-isothermal methods to estimate their kinetic parameters. The non-isothermal method (by thermogravimetric analyses) allowed estimating the activation energy for each limestone through the high calcination rate ranges. However, the kinetic parameters estimated by the quasi-isothermal method turned out in lower values, indicating the need to control the reactor atmosphere.

Abstract The continuous spectrum of a quantum mechanical (QM) system contains important information on the system. However, the normalization of wave functions of the continuous spectrum is often difficult and therefore is often omitted from the books on QM. We discuss this problem and show how we can overcome this problem technically, with some examples.

Abstract Most books on Thermodynamics explain what thermodynamic potentials are and how conveniently they describe the properties of physical systems. Certain books add that, to be useful, the thermodynamic potentials must be expressed in their “natural variables”. Here we show that, given a set of physical variables, an appropriate thermodynamic potential can always be defined, which contains all the thermodynamic information about the system. We adopt various perspectives to discuss this point, which to the best of our knowledge has not been clearly presented in the literature.

Abstract: En | Text: En | PDF: En

Ocimum gratissimum oil is used for various medicinal, food and cosmetic applications due to its high chemical variability. Local businesses have considered the economic exploitation of this plant. A specimen sampled at São Luís, MA, Brazil, with thymol and derivatives oil, was subjected to seasonal and circadian study, and to antifungal and antioxidant assays. It was possible to observe that the weather conditions showed a direct influence on the oil yield and variation of its constituents, mainly oxygenated monoterpenes and monoterpene hydrocarbons, with the predominance of thymol, γ-terpinene, and p-cymene. Principal component analysis (PCA) was able to justify the oil chemical variability of the seasonal (70%) and circadian (86%) study. Oil displayed inhibition for the fungus Corynespora cassiicola at a concentration above 0.3 µL mL-1, and it showed a more significant activity by comparison to thymol. Using 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical assay, the oil antioxidant activity was about 75% of thymol.

Resumo Macroinvertebrados fragmentadores consomem folhas preferencialmente condicionadas por fungos e bactérias que lhes oferece uma maior palatabilidade. Nas espécies do cerrado esse condicionamento está também associado às altas concentrações de elementos químicos limitantes à palatabilidade como alto teor de lignina e celulose, que tornam as folhas menos atrativas para os fragmentadores. O trabalho teve como objetivo avaliar a preferência alimentar de macroinvertebrados fragmentador ( Phylloicus sp.) por material vegetal de dois diferentes biomas (Cerrado e Mata Atlântica), após condicionamento em riacho de Mata Atlântica, observando suas características físicas e químicas. Foram coletadas folhas senescentes do aporte vegetal (AV) de espécies nativas da vegetação ripária nesses dois biomas, com periodicidade mensal em um trecho de 500 m de um córrego em cada bioma. O experimento foi delineado com dois tratamentos. O primeiro (T1) compreendeu discos de folhas do Cerrado (Chrysophyllum oliviforme) mais discos de folhas da Mata Atlântica (Miconia chartacea) que foram condicionadas em córrego de Mata Atlântica. O segundo tratamento (T2) envolveu discos de folhas da Mata Atlântica condicionadas em córrego da Mata Atlântica mais discos de folhas da Mata Atlântica condicionadas em córrego do Cerrado. Os dois testes apontaram diferenças significativas entre os dois tratamentos (T1 e T2). Para T1 houve consumo de discos de folha de M. chartacea por Phylloicus sp, mas não houve consumo dos discos de C. oliviforme , de Cerrado. Para T2, houve o consumo, porém a preferência pelas folhas de M. chartaceae condicionadas no córrego da Mata Atlantica foi consideravelmete maior. Os resultados apontam que Phylloicus sp, apresentou preferência alimentar pelo detrito de bioma de Mata Atlântica e rejeição pelo detrito do bioma Cerrado.

Abstract Macroinvertebrate shredders consume preferably leaves conditioned by fungi and bacteria which offer greater palatability to them. Plant species in Cerrado present high concentration of chemical elements such as lignin and cellulose, phenols and tanins thus making them less attractive for shredders consumption and limiting the palatability. This study aimed to evaluate the feeding preference of a macroinvertebrate shredder of the genus Phylloicus for plant material from two different biomes (Cerrado and Mata Atlântica), after conditioning in a stream of Mata Atlântica and observing their physical and chemical characteristics. Senescent leaves were collected, monthly from the litterfall of riparian vegetation in a 500 m stretch of a stream in each biome from August 2014 to January 201. The most abundant species in each stream was selected for the experiment. The experimental design consisted in with two treatments. The first (T1) comprised leaf discs from Chrysophyllum oliviforme (Cerrado species) together with leaf discs of Miconia chartacea (Atlantic Forest species) which were conditioned in the Atlantic Forest stream. The second treatment (T2) involved leaf discs of Miconia chartacea conditioned in Mata Altlântica and Cerrado streams. Both tests had showed significant differences between the two treatments (T1 and T2). For T1, there was consumption of M. chartacea leaf discs by Phylloicus sp., but there was no consumption of C. oliviforme discs. For T2, there was preference for M. chartaceae leaves conditioned in a stream of Mata Atlântica than in Cerrado stream. The results showed that Phylloicus sp., had presented preference for food detritus of the Mata Antlântica biome and rejection to the one from Cerrado biome.

Abstract: En | Text: En | PDF: En

Crude oils containing large quantities of waxes, and in situations where sudden temperature drops occur, a crystalline network can be formed, generating flow difficulties in production, transfer and offloading lines. Despite the scientific and economic importance of this phenomenon, correlations between the behavior of petroleum in relation to its pour point are scarce in the literature. In this work, nine crude oil samples were characterized regarding density, water content, wax fraction (one- and two-dimensional chromatography), pour point, yield stress and wax appearance temperature. The results showed that the storage conditions and oil characteristics had a strong influence on the pour point. Yield stress was influenced by initial temperature of the sample, cooling rate and shear rate during cooling. Finally, the content of aromatic compounds in oil with low concentration of n-alkanes can contribute to increase the pour point.

ABSTRACT Parasites are important components of communities and constitute great part of the biological diversity found in ecosystems, providing valuable information about their hosts and the environment in which they live. However, despite its importance, parasitic diversity is still not well known in some regions of Brazil, especially with respect to fish parasites in the Northeast Region. The present study aims to perform the survey of gill parasites of fish from two tropical estuaries located in northeastern Brazil: Paraíba and Mamanguape rivers. Two collections were made in each estuary, one during the dry period (November / 2013) and the other during the rainy season (July / 2014). The fish were caught using a beach seine net, dragged along the main channel margin. After the identification, biometry and necropsy of the fish, their parasites were collected, stored and identified. For each species of parasite, the values of prevalence, mean intensity and mean abundance were calculated. Of the 882 examined fish, belonging to four species, 145 were parasitized by at least one species of parasite. In total, 18 taxa of parasites of the groups Monogenea, Digenea, Nematoda, Copepoda and Isopoda were recorded, being the copepod Acusicola brasiliensis the most abundant species of parasite.

Resumo Este trabalho tem por objetivo avaliar o efeito da incorporação de cinza de resíduo sólido urbano nas propriedades físicas e mecânicas da cerâmica vermelha. Foram preparados corpos de prova por prensagem uniaxial a 20 MPa para queima a 750 °C, com incorporações de resíduo (70% de cinza de fundo e 30% de cinza volante) de até 20% em massa em argila caulinítica da região de Campos dos Goytacazes, RJ. As matérias-primas foram submetidas à análise química, mineralógica, física e morfológica. As propriedades físicas e mecânicas avaliadas nos corpos de prova foram: absorção de água, retração linear e tensão de ruptura à flexão. Os resultados sugerem a incorporação de quantidades em torno de 5% em massa de cinzas na argila para não prejudicar o comportamento mecânico da cerâmica, bem como evitar o aparecimento de porosidade aberta excessiva, podendo ser esta uma destinação final ambientalmente adequada para as cinzas de resíduo sólido urbano.

Abstract This study aims to evaluate the effect of the incorporation of municipal solid waste incineration (MSWI) ash in the physical and mechanical properties of red ceramic. Specimens were prepared by uniaxial mold-press at 20 MPa followed by firing at 750 °C, with residue incorporation (70 wt% of bottom ash and 30 wt% of fly ash) of up to 20 wt% in kaolinitic clay of Campos dos Goytacazes, RJ. Raw materials were subjected to chemical, mineralogical, physical and morphological analysis. The physical and mechanical properties evaluated were: water absorption, linear shrinkage, and flexural rupture strength. The results suggest the incorporation of amounts around 5 wt% of ash in clay to avoid damaging the mechanical behavior of ceramic and avoid the appearance of excessive porosity, and this may be a final destination environmentally suitable for the MSWI ashes.

Resumo O estudo dos invertebrados em substrato artificial com diferentes revestimentos antiincrustantes foi realizado com o intuito de responder as seguintes questões 1) Há menor acumulação de material orgânico nos substratos com revestimentos antiincrustantes? 2) A colonização de invertebrados é afetada pela liberação de biocidas dos revestimentos antiincrustantes? 3) A colonização dos invertebrados aquáticos é facilitada por material acumulado sobre a superfície do substrato? 4) A composição da assembléia é similar entre os diferentes revestimentos? Para realização deste estudo, quatro estruturas foram instaladas em 01 de fevereiro de 2007 no rio Baía. Em cada estrutura foram colocadas sete placas de madeira: cinco placas com aplicação de um tipo de revestimentos antiincrustantes (T1, T2, T3, T4 e T5), uma placa apenas com a aplicação do primer (Pr) e a outra placa permaneceu sem aplicação de nenhum revestimento (Cn). Ao final dos 365 dias em que os substratos ficaram submersos observou-se maior acumulação de material orgânico nos substratos dos revestimentos T2 e T3. Limnoperna fortunei foi registrada em todos os revestimentos testados, com maiores densidades encontradas no controle, primer, T2 e T3. A colonização de Chironomidae e Naididae sobre os substratos foi influenciada pela densidade de L. fortunei. A ordenação (NMDS) evidenciou a separação da assembléia de invertebrados entre os revestimentos. Os revestimentos T2 e T3 foram os mais similares ao controle e ao primer. Os resultados obtidos sugerem que revestimentos antiicrustantes aplicados sobre substratos dificultam a colonização de invertebrados, reduzindo a densidade e riqueza de invertebrados.

Abstract We conducted a study about invertebrates on artificial substrates with different antifouling paints in order to answer the following questions 1) is there lower accumulation of organic matter on substrates with antifouling paints, 2) is invertebrate colonization influenced by the release of biocides from antifouling paints, 3) is the colonization of aquatic invertebrates positively influenced by the material accumulated upon the substrate surface and 4) is the assemblage composition of invertebrates similar among the different antifouling paints? To answer these questions, four structures were installed in the Baía River in February 1st, 2007. Each structure was composed of 7 wood boards: 5 boards painted with each type of antifouling paints (T1, T2, T3, T4 and T5), one painted only with the primer (Pr) and the other without any paint (Cn). After 365 days, we observed a greater accumulation of organic matter in the substrates with T2 and T3 paint coatings. Limnoperna fortunei was recorded in all tested paints, with higher densities in the control, primer, T2 and T3. The colonization of Chironomidae and Naididae on the substrate was positively influenced by L. fortunei density. The non-metric multidimensional scaling (NMDS) of the invertebrate community provided evidence of the clear distinction of invertebrate assemblages among the paints. Paints T2 and T3 were the most similar to the control and primer. Our results suggest that antifouling paints applied on substrates hinder invertebrate colonization by decreasing the density and richness of invertebrates.
