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 Anaplasma marginale é uma bactéria Gram-negativa intracelular obrigatória de eritrócitos de ruminantes e responsável pela anaplasmose bovina. A diversidade genética de A. marginale tem sido caracterizada com base nas sequências das principais proteínas de superfície (MSPs), como a MSP1α. O objetivo deste estudo foi investigar a diversidade genética de A. marginale em bovinos no estado do Maranhão, Nordeste do Brasil. Dessa forma, 343 amostras de sangue foram submetidas ao ensaio iELISA, utilizando-se a proteína recombinante MSP5. Das 343 amostras de sangue, 235 (68,5%) foram escolhidas aleatoriamente e submetidas à extração de DNA, qPCR e PCR convencional para gene msp1α, para determinação das sequências de aminoácidos e classificação dos genótipos. Os resultados do iELISA mostraram 81,34% de soropositividade (279/343), enquanto qPCR revelou 224 amostras positivas (95,32%). Dentre estas na qPCR, 67,4% (151/224) mostraram-se positivas no PCR convencional. Das 50 sequências obtidas, 21 cepas não haviam sido relatadas anteriormente. Em relação aos genótipos, H (26/50) e E (18/50) foram os mais frequentes, enquanto os genótipos F e C foram identificados apenas duas vezes cada, e B e G uma vez cada. Em conclusão, alta prevalência e marcante diversidade genética de A. marginale foram observadas em rebanhos leiteiros no estado do Maranhão.
Abstract Anaplasma marginale is an obligate intracellular Gram-negative bacterium found in ruminants’ erythrocytes and is the etiological agent of bovine anaplasmosis. The bacterium’s genetic diversity has been characterized based on sequences of major surface proteins (MSPs), such as MSP1α. The aim of the present study was to investigate the genetic diversity of A. marginale in cattle in the state of Maranhão, northeastern Brazil. To this end, 343 blood samples were harvested and subjected to iELISA assays using the recombinant surface protein MSP5. Out of 343 blood samples, 235 (68.5%) were randomly chosen and submitted to DNA extraction, qPCR and conventional PCR targeting the msp1α gene to determine amino acid sequences and classify the genotypes. The iELISA results showed 81.34% seropositivity (279/343), whereas qPCR revealed 224 positive samples (95.32%). Among these qPCR-positive samples, 67.4% (151/224) were also positive in the cPCR. Among the 50 obtained sequences, 21 strains had not been previously reported. Regarding the genotypes, H (26/50) and E (18/50) were identified most often, while genotypes F and C were only identified twice each and B and G once each. In conclusion, high prevalence and genetic diversity for A. marginale were observed in dairy cattle herds in the state of Maranhão.

Resumo Objetivo: Descrever as características clínicas de crianças e adolescentes internados em unidade de terapia intensiva com COVID-19 confirmada. Método: Estudo prospectivo, multicêntrico, observacional, em 19 unidades de terapia intensiva pediátrica. Foram incluídos pacientes entre um mês e 19 anos, admitidos consecutivamente (março a maio de 2020). As características demográficas, clínico-epidemiológicas, o tratamento e os resultados foram coletados. Os subgrupos foram comparados de acordo com as comorbidades, idade < 1 ano e necessidade de ventilação mecânica invasiva. Um modelo de regressão logística multivariável foi utilizado para preditores de gravidade. Resultados: Setenta e nove pacientes foram incluídos (10 com síndrome inflamatória multi-ssistêmica). Mediana de idade, quatro anos; 54% eram do sexo masculino (síndrome inflamatória multissistêmica, 80%); 41% tinham comorbidades (síndrome inflamatória multissistêmica, 20%). Febre (76%), tosse (51%) e taquipneia (50%) foram comuns nos dois grupos. Sintomas graves egastrointestinais e marcadores inflamatórios mais elevados foram mais frequentes na presença de síndrome inflamatória multissistêmica. Infiltrados intersticiais pulmonares foram comuns em ambos os grupos, mas o derrame pleural foi mais prevalente no grupo com síndrome inflamatória multissistêmica (43% vs. 14%). A ventilação mecânica invasiva foi utilizada em 18% (mediana 7,5 dias); antibióticos, oseltamivir e corticosteroides foram utilizados em 76%, 43% e 23%, respectivamente, mas não a hidroxicloroquina. A mediana do tempo de permanência na unidade de terapia intensiva pediátrica foi de 5 dias; duas mortes ocorreram (3%) no grupo não- síndrome inflamatória multissistêmica. Os pacientes com comorbidades eram mais velhos, e as comorbidades foram independentemente associadas à necessidade de ventilação mecânica invasiva(OR 5,5; IC95%, 1,43-21,12; P 0,01). Conclusões: Nas unidades de terapia intensiva pediátrica brasileiras, a COVID-19 apresentou baixa mortalidade, a idade inferior a um ano não foi associada a um pior prognóstico, os pacientes com síndrome inflamatória multissistêmica apresentaram sintomas mais graves, biomarcadores inflamatórios mais elevados e uma grande predominância no sexo masculino, mas apenas a presença de comorbidades e doenças crônicas foi um preditor independente de gravidade.
Abstract Objective: To describe the clinical characteristics of children and adolescents admitted to intensive care with confirmed COVID-19. Method: Prospective, multicenter, observational study, in 19 pediatric intensive care units. Patients aged 1 month to 19 years admitted consecutively (March-May 2020) were included. Demographic, clinical-epidemiological features, treatment, and outcomes were collected. Subgroups were compared according to comorbidities, age < 1 year, and need for invasive mechanical ventilation. A multivariable logistic regression model was used for predictors of severity. Results: Seventy-nine patients were included (ten with multisystemic inflammatory syndrome). Median age 4 years; 54% male (multisystemic inflammatory syndrome, 80%); 41% had comorbidities (multisystemic inflammatory syndrome, 20%). Fever (76%), cough (51%), and tachypnea (50%) were common in both groups. Severe symptoms, gastrointestinal symptoms, and higher inflammatory markers were more frequent in multisystemic inflammatory syndrome. Interstitial lung infiltrates were common in both groups, but pleural effusion was more prevalent in the multisystemic inflammatory syndrome group (43% vs. 14%). Invasive mechanical ventilation was used in 18% (median 7.5 days); antibiotics, oseltamivir, and corticosteroids were used in 76%, 43%, and 23%, respectively, but not hydroxychloroquine. The median pediatric intensive care unit length-of-stay was five days; there were two deaths (3%) in the non- multisystemic inflammatory syndrome group. Patients with comorbidities were older and comorbidities were independently associated with the need for invasive mechanical ventilation (OR 5.5; 95% CI, 1.43-21.12; p = 0.01). Conclusions: In Brazilian pediatric intensive care units, COVID-19 had low mortality, age less than 1 year was not associated with a worse prognosis, and patients with multisystemic inflammatory syndrome had more severe symptoms, higher inflammatory biomarkers, and a greater predominance of males, but only comorbidities and chronic diseases were independent predictors of severity.

Cancer is one of the most prevalent diseases worldwide and the natural products could be a source of bioactive compounds. Passiflora mucronata (PM) belongs to a very known vegetal genus, although, there are no studies about cytotoxic activity or isolated compounds. Different extracts from PM were obtained by liquid-liquid partition (P), Soxhlet (Sox) and supercritical fluid (SFE1-5) extraction techniques, being compared concerning their yields, chemical profile and cytotoxicity. The Sox extracts showed the highest yields (6.03%: hexane; 2.51%: dichloromethane) followed by SFE (from 4.34 to 1.63%) and partitions (1.06 and 2.26%). The hexane partition (HP) showed the best cytotoxic activity against K562 cell line (IC50 = 18.72 µg.mL-1). From HP, the following compounds were identified and analysed its cytotoxic activities: β-amyrin (IC50 = 3.92 µg.mL-1), β-sitosterol (IC50 = 3.37 µg.mL-1), stigmasterol (IC50 = 3.31 µg.mL-1) and oleanolic acid. Stigmasterol induced about 75% of K562 total apoptosis. The compounds were tested against MA-104 cell line and the selective index (SI) attributed (SI >10 for all compounds). This indicates good selectivity to K562 cell line at the expense of MA-104. This is the first time, identifying those compounds to PM .

An analytical method for the determination of Al, Ca, Cd, Cr, Cu, Fe, Hg, K, Mg, Na and Zn in breast of conventional, country and Christmas chicken and turkey samples using microwave induced plasma optical emission spectrometry (MIP-OES) technique was developed. Samples were decomposed in a digester block with a reflux system under conditions optimized using a central composite design as it follows: 2 g of sample, in 7.5 mL of HNO3 during 180 min at 160 °C. The accuracy was evaluated by the analysis of standard reference material SRM 1546 meat homogenate (94 to 108%) and also by addition and recovery tests (80 to 121%). The highest concentrations, in mg kg-1, of Al (2.77), Ca (88.3), Cu (1.99), Fe (3.65), K (3236), Mg (292.62) and Na (312.03) were found in the breast of conventional chicken sample. Zinc presented high value in the breast of turkey sample (10.6 mg kg-1). However, the found concentrations were lower than the daily consumption limit established by supervisory agencies and reference limits from Brazilian legislation. Cadmium, Cr and Hg presented values below limit of quantification. In this way, it is evident that chicken breast should be consumed in a complementary way in a healthy diet.

ABSTRACT Stingless bee products such as honey, pollen, propolis, and geopropolis have been used for centuries in traditional medicine for the treatment of several illnesses. Investigation of the biological activity of stingless bee products, especially propolis and geopropolis, has revealed promising therapeutic properties. About 20% of total Neotropical stingless bees can be found in Brazil. Despite the species diversity, studies on their biological activity are scarce. The present review focuses on the antioxidant and antimicrobial activities of propolis and geopropolis from Brazilian stingless bees. In addition, the toxicity of these natural products was addressed. In order to provide new evidences for the toxic potential of propolis and geopropolis components, an in silico analysis was performed using the ADMET PredictorTM software. We observed that most of studies evaluated only crude ethanol extracts of a limited number of stingless bees species. Propolis and geopropolis displayed antioxidant capacity and antimicrobial activity. Concerning the toxic potential, the extracts of stingless bees propolis and geopropolis were considered safe. Nonetheless, in vitro and in vivo toxicological studies are still necessary.

RESUMO Austropuccinia psidii é o agente etiológico de uma das principais doenças do jambeiro-do-pará: a ferrugem-amarela. Em uma ocorrência dessa doença foi constatada a ação de um fungo hiperparasito sobre uredossoro de A. psidii. A partir de folhas lesionadas, dois isolados de Fusarium foram caracterizados por análise morfológica e molecular. Os resultados revelaram que esses organismos pertencem a dois complexos de espécies: Fusarium fujikuroi (FFSC) e Fusarium solani (FSSC). A ocorrência desses fungos micoparasitas é uma forma de controle biológico natural para esta ferrugem e o seu estudo contribuirá para o manejo da ferrugem amarela.
ABSTRACT Austropuccinia psidii is the etiologic agent of one of the major diseases affecting “jambeiro-do-pará”: yellow rust. During the incidence of yellow rust, the action of a hyperparasitc fungus on uredosore of A. psidii was observed. From injured leaves, two Fusarium isolates were characterized based on morphological and molecular analysis. Results evidenced that these organisms belong to two species complexes: Fusarium fujikuroi (FFSC) and Fusarium solani (FSSC). Occurrence of these mycoparasite fungi is a form of natural biological control for this rust and the study of these fungi will contribute to the management of yellow rust.

Abstract Annona leptopetala (R.E.Fr.) H. Rainer, Annonaceae, is used in folk medicine like antitumor and anti-inflammatory. The aim of this study was to determine chemical composition, toxicity and antitumor activity of A. leptopetala leaves volatile oil. Fresh leaves were hydrodistilled and then the volatile oil chemical composition was assessed by gas chromatography and mass spectrometry. Toxicity was assessed using haemolysis, micronucleus and acute toxicity protocols. Antitumor effects were determined in vitro and in vivo, using sulforhodamine B assay and sarcoma 180 murine tumor model, respectively. Spathulenol was the major component identified (12.56%). The volatile oil showed in vitro antitumor activity mainly in leukemia cell line (K-562), with Total growth inhibit (TGI) (concentration producing TGI) of 0.64 µg/ml. In other hand, the volatile oil <250 µg/ml did not inhibit HaCat non-tumor cell line growth. The concentration that produced 50% haemolysis was 372.8 µg/ml. The 50% lethal dose in mice was approximately 447.2 mg/kg intraperitoneally. Sarcoma 180 tumor growth inhibition rates were 59.29% and 58.77% at 100 and 150 mg/kg intraperitoneally, respectively. The volatile oil presented moderate gastrointestinal toxicity and no genotoxicity was observed at 350 mg/kg. Thus, the volatile oil shows antitumor activity with moderate toxicity.

Objective to describe the compliance of obstetric nursing care practices with the technical recommendations for normal birth. Methods cross-sectional study of records of normal birth care delivered by nurse-midwifes from two public maternity hospitals. The compliance assessment was based on the World Health Organization recommendations. The two-tailed Z-test was applied. Results Appropriate compliance was found for all practices assessed at maternity hospital A. At maternity hospital B, the timely clamping of the umbilical cord obtained partial compliance (70.9%). Prescriptions were found for a null diet, 85.7% and 59.8%; oxytocin during labor, 38.7% and 48.4%; and peri-parturient tocodynamometry, 30.5% and 47.2%, at maternity hospitals A and B, respectively. Conclusion the presence of the companion; use of the partogram; non-pharmacological care; intermittent auscultation of fetal heart beat; non-supinal maternal position during child birth; and postpartum application of intramuscular oxytocin obtain appropriate compliance, although inappropriate conducts were observed, such as prescriptions for a null diet, oxytocin and intrapartum tocodynamometry.

RESUMO: Para avaliar o efeito tóxico de formulações comerciais de óleo de neem, Azadirachta indica A. Juss, pré-pupas (PP), pupas jovens (PJ) e pupas velhas (PV) da Diatraea saccharalis F. (Lepidoptera: Crambidae) foram pulverizadas com o extrato diluído em água destilada, em concentrações de 0,0, 0,3, 0,5, 1,0 e 2,0%. O neem provocou diferentes efeitos sobre a mortalidade de pupas, dependendo da concentração. As pupas que não conseguiram emergir em adultos apresentaram anormalidades múltiplas. Quanto às pupas que emergiram em adultos (grupos PJ e PV), foi calculada a sua longevidade, que não diferiu da do grupo controle. As anormalidades encontradas em adultos estão relacionadas com a mortalidade em todos os tratamentos com exceção da concentração de 1,0%. A fecundidade foi avaliada de acordo com a oviposição de adultos fêmeas do grupo PJ, que não apresentaram anormalidades; dentro dos ovos depositados foi avaliado o número de ovos não desenvolvidos. Os resultados demonstraram redução no número de ovos depositados e aumento na porcentagem de ovos não desenvolvidos. Esses resultados mostraram que o óleo de neem tem elevado potencial para o controle do estágio mais resistente da broca da cana-de-açúcar, além de reduzir o aparecimento das fases subsequentes. Portanto, formulações comerciais de óleo de neem apresentam um efeito tóxico em pupas e adultos de D. Saccharalis.
ABSTRACT: To evaluate the toxic effect of commercial formulations of neem oil, Azadirachta indica A. Juss, pre-pupae (PP), young pupae (YP) and old pupae (OP) of Diatraea saccharalis F. (Lepidoptera: Crambidae) were sprayed with the diluted extract in distilled water at concentrations of 0.0, 0.3, 0.5, 1.0 and 2.0%. The neem extract caused concentration-dependent effects on mortality of pupae, and the pupae that failed to emerge in adults had multiple abnormalities. The longevity of pupae that emerged in adults (YP and OP group) did not differ from the control group. The abnormalities found in adults were related to mortality in all treatments, except at the concentration of 1.0%. Fertility was assessed according to the oviposition of adult females from the YP group that showed no abnormalities, through the evaluation of the number of deposited eggs and the rate of undeveloped eggs. The results showed a reduction in the number of eggs laid and an increase in the percentage of undeveloped eggs. These results show that neem oil has a high potential to control the toughest stage of the sugarcane borer and also reduces the further development. Therefore, commercial formulations of neem oil have a toxic effect on pupae and adults of D. saccharalis.

Resumo Um levantamento atualizado das plantas com sementes e análises relevantes acerca desta biodiversidade são apresentados. Este trabalho se iniciou em 2010 com a publicação do Catálogo de Plantas e Fungos e, desde então vem sendo atualizado por mais de 430 especialistas trabalhando online. O Brasil abriga atualmente 32.086 espécies nativas de Angiospermas e 23 espécies nativas de Gimnospermas e estes novos dados mostram um aumento de 3% da riqueza em relação a 2010. A Amazônia é o Domínio Fitogeográfico com o maior número de espécies de Gimnospermas, enquanto que a Floresta Atlântica possui a maior riqueza de Angiospermas. Houve um crescimento considerável no número de espécies e nas taxas de endemismo para a maioria dos Domínios (Caatinga, Cerrado, Floresta Atlântica, Pampa e Pantanal), com exceção da Amazônia que apresentou uma diminuição de 2,5% de endemicidade. Entretanto, a maior parte das plantas com sementes que ocorrem no Brasil (57,4%) é endêmica deste território. A proporção de formas de vida varia de acordo com os diferentes Domínios: árvores são mais expressivas na Amazônia e Floresta Atlântica do que nos outros biomas, ervas são dominantes no Pampa e as lianas apresentam riqueza expressiva na Amazônia, Floresta Atlântica e Pantanal. Este trabalho não só quantifica a biodiversidade brasileira, mas também indica as lacunas de conhecimento e o desafio a ser enfrentado para a conservação desta flora.
Abstract An updated inventory of Brazilian seed plants is presented and offers important insights into the country's biodiversity. This work started in 2010, with the publication of the Plants and Fungi Catalogue, and has been updated since by more than 430 specialists working online. Brazil is home to 32,086 native Angiosperms and 23 native Gymnosperms, showing an increase of 3% in its species richness in relation to 2010. The Amazon Rainforest is the richest Brazilian biome for Gymnosperms, while the Atlantic Rainforest is the richest one for Angiosperms. There was a considerable increment in the number of species and endemism rates for biomes, except for the Amazon that showed a decrease of 2.5% of recorded endemics. However, well over half of Brazillian seed plant species (57.4%) is endemic to this territory. The proportion of life-forms varies among different biomes: trees are more expressive in the Amazon and Atlantic Rainforest biomes while herbs predominate in the Pampa, and lianas are more expressive in the Amazon, Atlantic Rainforest, and Pantanal. This compilation serves not only to quantify Brazilian biodiversity, but also to highlight areas where there information is lacking and to provide a framework for the challenge faced in conserving Brazil's unique and diverse flora.

Neurofibromatoses (NF) constituem um grupo de doenças genéticas com predisposição ao crescimento de múltiplos tumores: tipo 1 (NF1), tipo 2 (NF2) e schwannomatose (SCH). Estas doenças têm em comum a origem neural dos tumores e os sinais cutâneos. Afetam cerca de 80 mil brasileiros. O maior conhecimento científico sobre as NF tem permitido melhor manejo clínico, redução da morbidade das complicações e melhor qualidade de vida. Na maioria dos casos, os especialistas em neurologia, dermatologia, genética clínica, oncologia e medicina interna estão capacitados a realizar o diagnóstico diferencial e identificar suas principais complicações. Devido à sua variabilidade fenotípica, curso progressivo, multiplicidade de órgãos acometidos e evolução imprevisível, as NF frequentemente necessitam de especialistas em NF para o acompanhamento. A Parte 1 deste texto oferece orientações para o diagnóstico de cada tipo de NF e discute os diagnósticos diferenciais com outras doenças. A Parte 2 oferecerá orientações em relação ao manejo clínico das NF.
Neurofibromatoses (NF) are a group of genetic multiple tumor growing predisposition diseases: neurofibromatosis type 1 (NF1), neurofibromatosis type 2 (NF2) and schwannomatosis (SCH), which have in common the neural origin of tumors and cutaneous signs. They affect nearly 80 thousand of Brazilians. In recent years, the increased scientific knowledge on NF has allowed better clinical management and reduced complication morbidity, resulting in higher quality of life for NF patients. In most cases, neurology, psychiatry, dermatology, clinical geneticists, oncology and internal medicine specialists are able to make the differential diagnosis between NF and other diseases and to identify major NF complications. Nevertheless, due to its great variability in phenotype expression, progressive course, multiple organs involvement and unpredictable natural evolution, NF often requires the support of neurofibromatoses specialists for proper treatment and genetic counseling. This Part 1 offers step-by-step guidelines for NF differential diagnosis. Part 2 will present the NF clinical management.

Methylcellulose was produced from the fibers of Mangifera indica L. Ubá mango seeds. MCD and MCI methylcellulose samples were made by heterogeneous methylation, using dimethyl sulfate and iodomethane as alkylating agents, respectively. The materials produced were characterized for their thermal properties (DSC and TGA), crystallinity (XRD) and Degree of Substitution (DS) in the chemical route. The cellulose derivatives were employed as mortar additive in order to improve mortar workability and adhesion to the substrate. These properties were evaluated by means of the consistency index (CI) and bond tensile strength (TS) tests. The methylcellulose (MCD and MCI) samples had CI increased by 27.75 and 71.54% and TS increased by 23.33 and 29.78%, respectively, in comparison to the reference sample. Therefore, the polymers can be used to produce adhesive mortars.

A estruturação do Sistema Nacional de Vigilância Epidemiológica do Brasil, em 1975, tornou obrigatória a notificação de algumas doenças transmissíveis com o objetivo de reduzir a carga destes eventos no país. Entretanto, as alterações no perfil epidemiológico destas doenças, associadas a características da sociedade contemporânea, determinam a constante adequação das atividades de vigilância a este cenário. Neste manuscrito, são descritos epidemiologia, tendências e diagnóstico diferencial das seguintes doenças dermatológicas de notificação compulsória no Brasil: aids, dengue, hanseníase, leishmaniose tegumentar americana, sarampo, rubéola e síndrome da rubéola congênita e sífilis. Também são apresentados os principais desafios atuais para o controle e prevenção para cada uma dessas doenças no Brasil
The development of a Brazilian National Surveillance System in 1975 led to a compulsory reporting of selected infectious diseases aiming to reduce the burden of these events in the country. However, shifts in the epidemiology of these diseases associated with modern life style, demand constant revision of surveillance activities. In this manuscript we present the epidemiology, trends and differential diagnosis of the following compulsory notifiable diseases in Brazil: Aids, dengue fever, hanseniasis, American tegumentary leishmaniasis, measles, rubella and congenital rubella syndrome and syphilis. Additionally, the current challenges for control and prevention of each disease are presented
