Resumo: A má nutrição afeta bilhões de indivíduos em todo o mundo e representa um desafio de saúde global. Este estudo teve como objetivo determinar a prevalência de má nutrição (desnutrição ou excesso de peso) entre díades mãe-filho em crianças menores de cinco anos no Brasil em 2019 e estimar as mudanças nessa prevalência de 2006 a 2019. Foram analisados dados individuais do Estudo Nacional de Alimentação e Nutrição Infantil (ENANI-2019) e da Pesquisa Nacional de Demografia e Saúde da Criança e da Mulher realizada em 2006 (PNDS 2006). Os desfechos de má nutrição incluíram mãe e filho com excesso de peso, mãe e filho desnutridos e a dupla carga de má nutrição, ou seja, mãe com excesso de peso e filho com qualquer forma de desnutrição (défict de crescimento, magreza ou baixo peso). Foram estimadas a prevalência e os intervalos de 95% de confiança (IC95%). A maioria das mulheres (58,2%) e 9,7% das crianças estavam acima do peso, 6,9% apresentaram déficit de crescimento e 3,1% das mães e 2,9% das crianças estavam abaixo do peso. A prevalência de excesso de peso na díade mãe-filho foi de 7,8% e foi estatisticamente maior no Sul do Brasil (9,7%; IC95%: 7,5; 11,9) do que no Centro-oeste (5,4%; IC95%: 4,3; 6,6). A prevalência de mãe com sobrepeso e filho com déficit de crescimento foi de 3,5%, com uma diferença estatisticamente significante entre os extremos de escolaridade materna [(0-7 vs. ≥ 12 anos de estudo), 4,8% (IC95%: 3,2; 6,5) and 2,1% (IC95%: 1,2; 3,0), respectivamente]. O excesso de peso na díade aumentou de 5,2% para 7,8% e a dupla carga de má nutrição aumentou de 2,7% para 5,2% desde 2006. A má nutrição nas díades mãe-filho brasileiras parece ser um problema crescente, sendo as mais vulneráveis aquelas com menor escolaridade e maior idade materna e residentes na Região Sul do Brasil.

Se analizaron datos individuales del Estudio Nacional de Alimentación y Nutrición Infantil (ENANI-2019) y de la Encuesta Nacional de Demografía y Salud del Niño y de la Mujer de 2006 (PNDS 2006). Los resultados de la malnutrición incluyeron a madre e hijo con sobrepeso, madre e hijo desnutridos y la doble carga de mala nutrición, es decir, madre con sobrepeso e hijo con cualquier forma de desnutrición (retardo en el crecimiento, emaciación o bajo peso). Se calcularon prevalencias y los intervalos de 95% de confianza (IC95%). La mayoría de las mujeres (58,2%) y el 9,7% de los niños tenían sobrepeso, el 6,9% de los niños presentaban retraso en el crecimiento, y el 3,1% de las madres y el 2,9% de los niños, bajo peso. La prevalencia de sobrepeso en la díada madre-hijo fue del 7,8%, estadísticamente mayor en el Sur de Brasil (9,7%; IC95%: 7,5; 11,9) que en el Centro-Oeste (5,4%; IC95%: 4,3; 6,6). La prevalencia de madres con sobrepeso y de niños con retraso del crecimiento fue del 3,5%, con una diferencia estadísticamente significativa entre los extremos de nivel educativo de la madre [(0-7 vs. ≥ 12 años de nivel educativo), 4,8% (IC95%: 3,2; 6,5) y 2,1% (IC95%: 1,2; 3,0), respectivamente]. El sobrepeso en la díada tuvo un aumento del 5,2% al 7,8%, y la doble carga de mala nutrición aumentó del 2,7% al 5,2% desde 2006. La malnutrición en la díada madre-hijo brasileña resulta ser un problema creciente, siendo las más vulnerables aquellas con menor escolaridad y mayor edad materna y residentes en la Región Sur de Brasil.
Abstract: Malnutrition affects billions of individuals worldwide and represents a global health challenge. This study aimed to determine the prevalence of malnutrition (undernutrition or overweight) among mother-child dyads in children under 5 years old in Brazil in 2019 and to estimate changes in this prevalence from 2006 to 2019. Individual-level data from the Brazilian National Survey on Child Nutrition (ENANI-2019) and the Brazilian National Survey of Demography and Health of Women and Children carried out in 2006 (PNDS 2006) were analyzed. Malnutrition outcomes in mother-child dyads included overweight mother and child, undernourished mother and child, and the double burden of malnutrition, i.e., overweight mother and child having any form of undernourishment (stunting, wasting, or underweight). Prevalence and 95% confidence intervals (95%CI) were estimated. Most women (58.2%) and 9.7% of the children were overweight, 6.9% were stunted, and 3.1% of mothers and 2.9% of the children were underweight. The prevalence of overweight in the mother-child dyad was 7.8% and was statistically higher in Southern Brazil (9.7%; 95%CI: 7.5; 11.9) than in the Central-West (5.4%; 95%CI: 4.3; 6.6). The prevalence of overweight mother and stunted child was 3.5%, with statistically significant difference between the extremes of the mother’s education [0-7 vs. ≥ 12 years, 4.8% (95%CI: 3.2; 6.5) and 2.1%, (95%CI: 1.2; 3.0), respectively]. Overweight in the dyad increased from 5.2% to 7.8%, and the double burden of malnutrition increased from 2.7% to 5.2% since 2006. Malnutrition in Brazilian mother-child dyads seems to be a growing problem, and dyads with lower formal education, higher maternal age, and from the South Region of Brazil were more vulnerable.

Abstract Several phytogeographic regions (Cerrado, Pantanal, Atlantic Forest, Gran Chaco, and Chiquitano Dry Forests) converge in the state of Mato Grosso do Sul, Brazil, and influence regional biodiversity. Despite a list of birds in the state of Mato Grosso do Sul being published by Nunes et al. (2017), it is necessary to update and critically review avifauna records. In this study, we gathered the results of several records obtained from species lists and online data platforms of the 336 sites in this state over the last decades and grouped them into Main (Primary and Secondary) and Tertiary Lists. The avifauna of Mato Grosso do Sul is composed of 678 species, of which 643 (95%) have records proving their occurrence (Primary List), whereas 34 still lack documentation (Secondary List). The number of related species for Mato Grosso do Sul represents 34% of the Brazilian avifauna. Some species stand out for their unique occurrence in Mato Grosso do Sul, such as Melanerpes cactorum, Celeus lugubris, Phaethornis subochraceus, and Cantorchilus guarayanus, reflecting the influence of different phytogeographic regions of the Chaco and Chiquitano Dry Forests. Migrants represent 20% of the bird community occurring in the state, of which 93 species correspond to migrants from various regions of South America (south and west) and 40 to boreal migrants. Thirty-three species perform nomadic movements across the Pantanal Plain and other regions of the state. Thirty-one species are included in some conservation-threatened categories of global and/or national endangered species lists. Other 30 species are included in the near-threatened category at the global level and 23 at the national level. In addition, species typical of dry forests (in Serra da Bodoquena and Maciço do Urucum) and those from the Atlantic Forest in the south of the state deserve attention due to their restricted distribution and the high anthropogenic pressure on their habitat.

Abstract Background: The VI Brazilian Consensus on Autoantibodies against HEp-2 cells for determination of autoantibodies against cellular constituents on HEp-2 cells was held on September, 2019, in Fortaleza (CE, Brazil). The guidelines in this edition were formulated by the group of Brazilian experts discussing the classification of complex patterns, the classification of the nuclear discrete dots (few and multiple), the identification of the discrete fine speckled pattern (AC-4a) and improvements on the ANA report. Mainbody: Sixteen Brazilian researchers and experts from universities and clinical laboratories representing the various geographical regions of Brazil participated in the meeting. Four main topics were discussed: (1) How to classify patterns with fluorescence in more than one cell compartment considering three relevant categoris: composite patterns, mixed patterns and multiple patterns; (2) The splitting of the discrete nuclear dots pattern into the multiple discrete nuclear dots (AC-6) and few discrete nuclear dots (AC-7) patterns, respectively; (3) Inclusion of a novel nuclear pattern characterized by discrete fine speckled pattern highly associated with antibodies to SS-A/Ro60, classified as AC-4a. In addition, adjustments on the Brazilian Consensus nomenclature were implemented aiming to harmonize the designation of some patterns with the International Consensus on ANA Patterns (ICAP). Furthermore, the designations of the PCNA-like pattern (AC-13), CENP-F-like pattern (AC-14) and Topo I-like pattern (AC-29) were adjusted in accordance to ICAP. Finally, there was a recommendation for adjustment in the test report in order to address the status of nuclear envelope staining. For all topics, the aim was to establish specific guidelines for laboratories and clinicians. All recommendations were based on consensus among participants. All recommendations from the V Consensus were maintained and there was relevant progress in the BCA/HEp-2 guidelines and further harmonization with ICAP. Conclusion: The VI BCA/HEp-2 edition was successful in establishing important recommendations regarding the classification of complex patterns, in supporting the identification of a novel pattern within the AC-4 group and in the harmonization process with the ICAP terminology.

RESUMO Objetivo: Descrever as práticas de ressuscitação volêmica em unidades de terapia intensiva brasileiras e compará-las com as de outros países participantes do estudo Fluid-TRIPS. Métodos: Este foi um estudo observacional transversal, prospectivo e internacional, de uma amostra de conveniência de unidades de terapia intensiva de 27 países (inclusive o Brasil), com utilização da base de dados Fluid-TRIPS compilada em 2014. Descrevemos os padrões de ressuscitação volêmica utilizados no Brasil em comparação com os de outros países e identificamos os fatores associados com a escolha dos fluidos. Resultados: No dia do estudo, foram incluídos 3.214 pacientes do Brasil e 3.493 pacientes de outros países, dos quais, respectivamente, 16,1% e 26,8% (p < 0,001) receberam fluidos. A principal indicação para ressuscitação volêmica foi comprometimento da perfusão e/ou baixo débito cardíaco (Brasil 71,7% versus outros países 56,4%; p < 0,001). No Brasil, a percentagem de pacientes que receberam soluções cristaloides foi mais elevada (97,7% versus 76,8%; p < 0,001), e solução de cloreto de sódio a 0,9% foi o cristaloide mais comumente utilizado (62,5% versus 27,1%; p < 0,001). A análise multivariada sugeriu que os níveis de albumina se associaram com o uso tanto de cristaloides quanto de coloides, enquanto o tipo de prescritor dos fluidos se associou apenas com o uso de cristaloides. Conclusão: Nossos resultados sugerem que cristaloides são usados mais frequentemente do que coloides para ressuscitação no Brasil, e essa discrepância, em termos de frequências, é mais elevada do que em outros países. A solução de cloreto de sódio 0,9% foi o cristaloide mais frequentemente prescrito. Os níveis de albumina sérica e o tipo de prescritor de fluidos foram os fatores associados com a escolha de cristaloides ou coloides para a prescrição de fluidos.
Abstract Objective: To describe fluid resuscitation practices in Brazilian intensive care units and to compare them with those of other countries participating in the Fluid-TRIPS. Methods: This was a prospective, international, cross-sectional, observational study in a convenience sample of intensive care units in 27 countries (including Brazil) using the Fluid-TRIPS database compiled in 2014. We described the patterns of fluid resuscitation use in Brazil compared with those in other countries and identified the factors associated with fluid choice. Results: On the study day, 3,214 patients in Brazil and 3,493 patients in other countries were included, of whom 16.1% and 26.8% (p < 0.001) received fluids, respectively. The main indication for fluid resuscitation was impaired perfusion and/or low cardiac output (Brazil: 71.7% versus other countries: 56.4%, p < 0.001). In Brazil, the percentage of patients receiving crystalloid solutions was higher (97.7% versus 76.8%, p < 0.001), and 0.9% sodium chloride was the most commonly used crystalloid (62.5% versus 27.1%, p < 0.001). The multivariable analysis suggested that the albumin levels were associated with the use of both crystalloids and colloids, whereas the type of fluid prescriber was associated with crystalloid use only. Conclusion: Our results suggest that crystalloids are more frequently used than colloids for fluid resuscitation in Brazil, and this discrepancy in frequencies is higher than that in other countries. Sodium chloride (0.9%) was the crystalloid most commonly prescribed. Serum albumin levels and the type of fluid prescriber were the factors associated with the choice of crystalloids or colloids for fluid resuscitation.

Abstract The Program for Biodiversity Research (PPBio) is an innovative program designed to integrate all biodiversity research stakeholders. Operating since 2004, it has installed long-term ecological research sites throughout Brazil and its logic has been applied in some other southern-hemisphere countries. The program supports all aspects of research necessary to understand biodiversity and the processes that affect it. There are presently 161 sampling sites (see some of them at Supplementary Appendix), most of which use a standardized methodology that allows comparisons across biomes and through time. To date, there are about 1200 publications associated with PPBio that cover topics ranging from natural history to genetics and species distributions. Most of the field data and metadata are available through PPBio web sites or DataONE. Metadata is available for researchers that intend to explore the different faces of Brazilian biodiversity spatio-temporal variation, as well as for managers intending to improve conservation strategies. The Program also fostered, directly and indirectly, local technical capacity building, and supported the training of hundreds of undergraduate and graduate students. The main challenge is maintaining the long-term funding necessary to understand biodiversity patterns and processes under pressure from global environmental changes.

Resumo Neste trabalho, um fotorreator contínuo foi projetado e montado, usando peças recicláveis e de baixo custo, para desenvolver tratamentos químicos, baseados em processos oxidativos avançados (AOP), de efluentes têxteis altamente coloridos por azo-compostos. A fim de avaliar a eficiência deste sistema reacional sustentável, foi investigada a performance de três tratamentos destrutivos (UV/H2O2, Fenton e foto-Fenton) sobre a remoção de cor de soluções aquosas do corante denominado Reactive Black 5 (RB5). O efeito da concentração de oxidante (H2O2) e da carga inicial de corante sobre a taxa de remoção de cor foi também analisado. Os resultados mostraram que, independentemente das condições operacionais iniciais, o processo foto-Fenton alcançou as taxas mais elevadas de degradação, especialmente quando a maior razão entre as concentrações do oxidante e do corante foi empregada ([H2O2]: [RB5] = 24.5 mg L-1: 25 mg L-1), com a completa remoção de cor em apenas 10 minutos de experimento. Usando-se as mesmas condições iniciais, os processos Fenton e UV/H2O2 foram também capazes de descolorir completamente o poluente têxtil, entretanto precisando de 25 minutos e 45 minutos de reação, respectivamente. O efeito do pH sobre a descoloração pelo processo foto-Fenton foi também investigado, mostrando a mesma elevada performance nos pHs 3 e 4. O perfil de degradação obtido no tratamento foto-Fenton foi devidamente modelado pela cinética de pseudo-primeira ordem. O fotorreator contínuo de baixo custo mostrou-se bastante útil na degradação do corante RB5, principalmente quando o processo foto-Fenton foi empregado.
Abstract In this work, a flow photoreactor was designed and set up using low-cost and recyclable parts to develop chemical treatments based on advanced oxidation processes (AOP) of highly colored textile wastewater. To evaluate this sustainable system´s efficiency, we investigated and compared the performance of three types of destructive methods (UV/H2O2, Fenton, and photo-Fenton) on the decolorization of aqueous solutions of Reactive Black 5 dye (RB5). We also analyzed the effect of the oxidant and dye concentrations on the rate of color removal in each one of the three methods. The results showed that, regardless of the initial operating conditions, the photo-Fenton process achieved the highest degradation rates, particularly when the highest ratio between the oxidant and dye concentrations was used ([H2O2]: [RB5] = 24.5 mg L-1: 25 mg L-1), leading to complete color removal within only 10 minutes of reaction. With the same initial condition, the Fenton and UV/H2O2 processes were also capable of removing the color entirely, even though they demanded more extended runs of 25 min. and 45 min., respectively. The effect of pH on the decolorization by the photo-Fenton process was also investigated, showing the same high performance at pHs 3 and 4. The degradation profile achieved by the photo-Fenton treatment was appropriately fitted by a pseudo-first-order kinetic. The non-expensive photoreactor proved to be quite useful for the degradation of the RB5, mainly when this azo dye underwent the photo-Fenton process.

RESUMO O estudo analisou como incentivos político-eleitoreiros influenciam a gestão fiscal dos municípios brasileiros e seus desdobramentos nos resultados eleitorais. Nas estimações realizadas dois achados se sobressaem. O primeiro é que apesar de existir um aumento nos investimentos, visíveis à população e associados pela literatura a resultados eleitorais favoráveis, os partidos reconduzidos também possuem uma estrutura de pessoal mais sustentável e melhores condições de liquidez no curto prazo, com desempenhos alavancados em períodos estratégicos, como em anos eleitorais. O segundo é que, apesar dos partidos com recondução sinalizarem melhores níveis na condição fiscal nos três ciclos políticos, no período pós-eleitoral as médias se retraem para patamares inferiores ao alcançado pela gestão no início do primeiro mandato. Portanto, embora indiquem melhores condições fiscais em anos eleitorais, o efeito da sinalização se inverte no ano seguinte. Como o impacto das decisões da gestão não estará disponível para o eleitorado imediatamente no período eleitoral, os políticos podem utilizar de estratégias fiscais para evitar que o equilíbrio fiscal seja prejudicado nos momentos estratégicos e postergar o desembolso para o ano pós-eleitoral, decisão que não prejudicaria a gestão fiscal atual e o recebimento de votos.
ABSTRACT The study analyzed how political-electoral incentives influence the fiscal management of Brazilian municipalities and their effects on electoral results. Two findings stand out, the first is that although there is an increase in investments, visible to the population and associated in the literature with favorable electoral results, the re-elected parties also have a more sustainable personnel structure and better liquidity conditions in the short-term with leveraged performance in strategic periods, such as in electoral years. The second is that despite the fact that the newly elected parties sign higher levels of fiscal condition in the three political cycles, in the post-election period the averages shrink to levels lower than those achieved by management at the beginning of the first-term. Therefore, despite indicating better fiscal conditions in electoral years, the effect of signaling is reversed in the following year. As the impact of management decisions will not be available to the electorate immediately during the election period, politicians can use fiscal strategies to avoid fiscal balance being impaired in strategic periods and postpone disbursement for the post-election year, a decision that would not hurt the current fiscal management and the receipt of votes.

Abstract This study aimed to evaluate the effect of two Embryo Manipulation Solutions (EMS and EMS supplemented) in maintenance of the viability of embryos, initially using structures derived from mice (first phase). Next, the efficiency of these solutions in routines of bovine embryo transfer was evaluated (second stage). Mice embryos were used in the stages of early blastocyst, and compact morula grades I and II. These embryos were initially randomly distributed and maintained for four hours in three solutions: Modified phosphate buffered saline (PBS; Control); EMS (treatment 1), and EMS supplemented (treatment 2). Subsequently, they were cultured in TCM 199 medium and evaluated in terms of total number of cells, morphometric characteristics, ultra structural aspects, detection of cell apoptosis, and quantification of Hsp70.3 gene expression. In the second phase, these same solutions were tested in the transfer of quality I and II bovine embryos (excellent and good). These embryos were transferred fresh to 58 recipients. The results showed that the total number of cells in embryos expanded blastocyst (ExB), the number of apoptotic cells, the cell, nuclear, nucleolar diameter and the nucleus/nucleolus ratio was similar among the treatments. The pregnancy rate shown on second phase was also similar. However, the EMS supplemented expressed more Hsp70.3 than EMS. The expression of Hsp70.3 was also greater for embryos in EMS than that of EMS supplemented. The McII embryos, EMS and EMS supplemented samples also expressed more Hsp70.3 compared to control embryos. In conclusion, the tested solutions can be used in routine embryo transfer techniques, replacing modified PBS solution as an effective media in maintaining embryo viability.

Abstract Background: The V Brazilian Consensus for determination of autoantibodies against cellular constituents on HEp-2 cells, held in Brasilia (DF, Brazil) on August 27, 2016, discussed the harmonization between the Brazilian Consensus on ANA (BCA) guidelines and the International Consensus on ANA Patterns (ICAP) recommendations (www.anapatterns.org). Initial guidelines were formulated by the group of Brazilian experts with the purpose of guiding and enabling Brazilian clinical laboratories to adopt recommendations and to provide a common standard for national and international consensuses. Mainbody: Twenty Brazilian researchers and experts from universities and clinical laboratories representing the various geographical regions of the country participated in the meeting. Three main topics were discussed, namely the harmonization between the BCA guidelines and latest recommendations of the ICAP initiative, the adjustment of the terminology and report on HEp-2 patterns, and a reassessment of quality assurance parameters. For the three topics, our aim was to establish specific guidelines. All recommendations were based on consensus among participants. There was concrete progress in the adjustment of the BCA guidelines to match the ICAP guidelines. To a certain extent, this derives from the fact that ICAP recommendations were largely based on the algorithm and recommendations of the IV Brazilian ANA Consensus, as consistently recognized in the ICAP publications and presentations. However, although there is great overlap between the two Consensuses, there are some point divergences. These specific items were individually and extensively discussed, and it was acknowledged that in several points ICAP improved recommendations previously issued by the Brazilian ANA Consensus and these changes were readily implemented. Regarding some specific topics, the BCA panel of experts felt that the previously issued recommendations remained relevant and possibly will require further discussion with ICAP. The term anti-cell antibodies was adopted as the recommended designation, recognizing that the assay addresses antibodies against antigens in the nucleus and in other cell compartments. However, the acronym ANA HEp-2 was maintained due to historical and regulatory reasons. It was also signalized that the latest trend in ICAP is to adopt the term Indirect Immunofluorescent Assay on HEp-2 cell substrate (HEp-2 IIFA). In addition, the quality assurance strategies previously presented were ratified and emphasized. Conclusion: The V BCA edition was successful in establishing an overall harmonization with the ICAP recommendations for interpretation of the HEp-2 IIFA test, pinpointing the perspectives in filling the remaining gaps between both initiatives.

Abstract Over the last few decades, the systematics and evolution of carcharodontosaurids, a group of large predatory dinosaurs, from North Africa have been better understood mainly due the discovery of new species. We review this record here and discuss its importance for understanding the evolution and ecology of these dinosaurs. North Africa has one of the best records of carcharodontosaurid species. These species show dietary specializations and paleogeographic distributions similar to other top predatory theropods such as Abelisauridae and Spinosauridae. However, carcharodontosaurids have a wider distribution than other large theropods. The middle Cretaceous of North Africa was characterized by the niche overlap between large predators. This evidence increases our understanding of the evolution of Carcharodontosauridae in a highly competitive region, a conjuncture rarely reported for large top predators.

RESUMO: Erwinia psidii é o agente causal da seca dos ponteiros da goiabeira ( Psidium guajava ), uma importante doença dessa cultura no Brasil. O patógeno afeta folhas, frutos, ramos e brotações, reduzindo significativamente a produtividade da cultura. A disseminação do patógeno ocorre por meio de material propagativo contaminado, porém assintomático. Os objetivos do trabalho foram avaliar o uso da BIO-PCR e da PCR convencional para detectar E. psidii em plantas inoculadas em casa de vegetação e em plantas sintomáticas e assintomáticas em pomares de goiabeira. A estirpe IBSBF 1576 de E. psidii foi inoculada (107UFC mL-1) em brotações novas de mudas de goiabeira e o tecido foi analisado nos tempos 0, 5, 10, e 15 dias após a inoculação. Sintomas foram observados após 5 dias e todas as plantas inoculadas foram positivas por PCR em todos os tempos avaliados, pelos dois métodos (BIO-PCR e PCR convencional). Sob condições de infecção natural em campo, três pomares foram avaliados por BIO-PCR. De cada pomar, foram coletadas 40 amostras, sendo 20 com e 20 sem sintomas. PCR foi positiva para 58 das 60 amostras sintomáticas (96,7%) e para 6,7% das amostras assintomáticas, demonstrando que o método pode ser usado para detectar o patógeno nos estágios iniciais da infecção. Este método poderá ser útil como uma ferramenta para a diagnose e para monitorar a sobrevivência e disseminação da bactéria e, consequentemente, novos focos da doença.
ABSTRACT: Erwinia psidii causes bacterial blight of guava ( Psidium guajava ), an important disease of this crop in Brazil. The pathogen affects branches and twigs of guava trees, reducing yield significantly. Bacterial dissemination often occurs through contaminated but asymptomatic propagating plant material. The objectives of this research were to evaluate the use of BIO-PCR and conventional PCR to detect E. psidii in inoculated guava plants grown in a greenhouse and in symptomatic and asymptomatic trees from guava orchards. Erwinia psidii strain IBSBF 1576 was inoculated (107CFU mL-1) into young guava shoots and plant tissue was analysed at 0, 5, 10, and 15 days after inoculation. Symptoms were observed after 5 days and all inoculated shoots were PCR positive at all times, by both BIO-PCR and conventional PCR. Under natural infection conditions, 40 samples were tested by BIO-PCR from each of three guava orchards, 20 showing symptoms and 20 asymptomatic. PCR was positive for 58 out of 60 symptomatic samples (96.7%) and for 6.7% of asymptomatic samples, showing that the method can be used to detect the pathogen at early stages of infection. This PCR method may be used as a diagnostic tool to assess bacterial survival, dissemination and disease outbreaks.

Abstract JC virus (JCV) is a member of the Polyomaviridae family and is associated to a severe disease known as progressive multifocal leukoencephalopathy, PML, which is gradually increasing in incidence as an opportunistic infection among AIDS patients. The present study aimed to investigate the occurrence of JCV among HIV-1 carriers including their types and molecular subtypes and the possible association with disease. Urine samples from 66 HIV-1 infected subjects were investigated for the presence of the virus by amplifying VP1 (215 bp) and IG (610 bp) regions using the polymerase chain reaction. JCV was detected in 32% of the samples. The results confirmed the occurrence of type B (subtype Af2); in addition, another polyomavirus, BKV, was also detected in 1.5% of samples of the HIV-1 infected subjects. Apparently, there was no significant difference between mono- (HIV-1 only) and co-infected (HIV-1/JCV) subjects regarding their TCD4+/TCD8+ lymphocyte counts or HIV-1 plasma viral load. Self admitted seizures, hearing and visual loses were not significantly different between the two groups.

ABSTRACT: Highland environments favor accumulation and preservation of soil organic matter (SOM) due to low temperatures, leading to the formation of Histosols. The Itatiaia National Park (INP), Rio de Janeiro, Brazil, offers conditions for preservation of SOM deposited over time, which has led to the formation of these soils. The objective of this study was to characterize Histosols in this environment, with the premise that it may provide evidence of changes in vegetation. Organossolos (Histosols) were sampled, characterized, described, and analyzed for their properties, stable isotopes of 12C and 13 14 15 14 C, N and N, and dating of organic matter through C. The soils were classified in the Brazilian Soil Classification System as Organossolo Háplico Hêmico típico - RJ-01 (Haplohemists) and Organossolo Fólico Sáprico cambissólico - RJ-02 (Udifolists). The morphological properties, degree of transformation, and chemical fractioning of SOM were consistent with hemic and sapric materials. The δ13C and δ15N isotopic analyses showed a difference in the contribution of plant materials. In RJ-01, there was previous influence of algae, due to poor drainage, and depletion of δ13C, suggesting a mix of C3 and C4 plants. RJ-02 showed influence of C3 type plants. The 14C dating for RJ-01 was 3280±80 years, and for RJ-02, 2005±5 years (modern age).
