Abstract It is repeatedly stressed the need to characterize the extant biodiversity in tropical ecosystems. However, inventory studies are still progressing slowly in dry ecosystems, leading to the underestimation of their true biodiversity and hindering conservation efforts. In this study, we present primary and secondary data, along with an updated list of amphibians and reptiles from two localities in the São Francisco-Gurguéia region in Piauí. Additionally, we compare the species composition between nine areas within the Caatinga, which were sampled using standardized methods over the past ten years, to examine broader spatial patterns of community composition. To survey reptiles and amphibians, we employed similar methods and sampling efforts in two areas within the Serra das Confusões National Park (SCNP) region. Our surveys recorded a total of 73 species of amphibians and reptiles, of which 24 are new distribution records for the SCNP region. Consequently, our findings increase the known herpetofauna in the region to 94 species. Despite their proximity, the two sites in the SCNP region exhibited only 42% similarity in species composition, and they differed significantly from other areas within the Caatinga. Furthermore, even the closer Caatinga areas presented differences in species composition, highlighting the necessity to evaluate biodiversity across the landscape and contribute to understanding biogeographic patterns.
Resumo É repetidamente enfatizada a necessidade de caracterizar a biodiversidade vivente em ecossistemas tropicais. No entanto, os estudos de inventário ainda estão progredindo lentamente em ecossistemas secos, levando à subestimação de sua verdadeira biodiversidade e dificultando os esforços de conservação. Neste estudo, apresentamos dados primários e secundários, juntamente com uma lista atualizada de anfíbios e répteis de duas localidades na região de São Francisco-Gurguéia, do Piauí. Além disso, comparamos a composição de espécies entre nove áreas dentro da Caatinga, que foram amostradas usando métodos padronizados nos últimos dez anos, para examinar padrões espaciais mais amplos de composição da comunidade. Para estudar répteis e anfíbios, utilizamos métodos e esforços de amostragem semelhantes em duas áreas na região do Parque Nacional da Serra das Confusões (PNSC). Nossos levantamentos registraram um total de 73 espécies de anfíbios e répteis, das quais 24 são novos registros de distribuição para a região do PNSC. Consequentemente, nossos resultados aumentam a herpetofauna conhecida na região para 94 espécies. Apesar da proximidade, os dois locais na região do PNSC exibiram apenas 42% de similaridade na composição de espécies e diferiram significativamente de outras áreas dentro da Caatinga. Mesmo áreas mais próximas da Caatinga apresentaram diferenças na composição de espécies, destacando a necessidade de avaliar a biodiversidade em toda a paisagem e contribuir para a compreensão de padrões biogeográficos.

The dielectric barrier discharge ionization detector (BID) is one of the most modern detectors commercially available for gas chromatography (GC). Its technology based on the sample ionization through the energy released from the helium plasma generation process gives it the ability to act as a universal detector and a greater response to various types of compounds compared to the well-established flame ionization detector (FID). In this study, polycyclic aromatic hydrocarbons (PAHs), organophosphates (OPPs) and organochlorines pesticides (OCPs) were investigated. The parameters that could explain the performance of the BID and FID detectors were: structural factors, ionization energy (IE) and energy of the highest occupied molecular orbital (EHOMO), which were obtained by density functional theory (DFT). The relative (BID/FID) responses to PAHs and pesticides were about 1.8 and 3.0 times greater than FID, respectively. Less structural dependence of the BID signal compared to the FID signal was observed. Among the parameters calculated by DFT, the IE was the one that most seemed to have influenced the response of the two detectors studied. The theoretical data proved to be quite consistent to explain the trends observed experimentally, especially to the BID.

For billions of years, the phenomena of life and biocatalysis have been intertwined. If in the beginning biocatalysis was fundamental for the origin of life, currently it is very important for the cleaner production of pharmaceuticals and fine chemical intermediates. There is no doubt that drugs have brought great benefits to humanity, but currently, the expectations of modern society are focused on drugs with greater safety, less environmental impact, more sustainable practices, and less energy use. This review intends to show how the challenges for the production of some low molecular weight drugs produced by synthetic routes that involve at least one biotechnological step using microorganisms or enzymes were faced. These biotechnological drug production routes are more sustainable than conventional synthetic routes, as they produce a much smaller amount of waste, use moderate reaction conditions, have lower energy consumption, and have lower metal consumption, in addition to being more selective. Additionally, many natural products have structures too complex to be produced exclusively by chemical routes. The large-scale and economical production of these drugs is of great importance for fighting cancer as well as inflammatory, infectious, autoimmune, metabolic, hormonal, cardiovascular, and neurological diseases, among others.

OBJECTIVES: To prospectively evaluate demographic, anthropometric and health-related quality of life (HRQoL) in pediatric patients with laboratory-confirmed coronavirus disease 2019 (COVID-19) METHODS: This was a longitudinal observational study of surviving pediatric post-COVID-19 patients (n=53) and pediatric subjects without laboratory-confirmed COVID-19 included as controls (n=52) was performed. RESULTS: The median duration between COVID-19 diagnosis (n=53) and follow-up was 4.4 months (0.8-10.7). Twenty-three of 53 (43%) patients reported at least one persistent symptom at the longitudinal follow-up visit and 12/53 (23%) had long COVID-19, with at least one symptom lasting for >12 weeks. The most frequently reported symptoms at the longitudinal follow-up visit were headache (19%), severe recurrent headache (9%), tiredness (9%), dyspnea (8%), and concentration difficulty (4%). At the longitudinal follow-up visit, the frequencies of anemia (11% versus 0%, p=0.030), lymphopenia (42% versus 18%, p=0.020), C-reactive protein level of >30 mg/L (35% versus 0%, p=0.0001), and D-dimer level of >1000 ng/mL (43% versus 6%, p=0.0004) significantly reduced compared with baseline values. Chest X-ray abnormalities (11% versus 2%, p=0.178) and cardiac alterations on echocardiogram (33% versus 22%, p=0.462) were similar at both visits. Comparison of characteristic data between patients with COVID-19 at the longitudinal follow-up visit and controls showed similar age (p=0.962), proportion of male sex (p=0.907), ethnicity (p=0.566), family minimum monthly wage (p=0.664), body mass index (p=0.601), and pediatric pre-existing chronic conditions (p=1.000). The Pediatric Quality of Live Inventory 4.0 scores, median physical score (69 [0-100] versus 81 [34-100], p=0.012), and school score (60 [15-100] versus 70 [15-95], p=0.028) were significantly lower in pediatric patients with COVID-19 at the longitudinal follow-up visit than in controls. CONCLUSIONS: Pediatric patients with COVID-19 showed a longitudinal impact on HRQoL parameters, particularly in physical/school domains, reinforcing the need for a prospective multidisciplinary approach for these patients. These data highlight the importance of closer monitoring of children and adolescents by the clinical team after COVID-19.

Exercising prior to experimental infarction may have beneficial effects on the heart. The objective of this study was to analyze studies on animals that had exercised prior to myocardial infarction and to examine any benefits through a systematic review and meta-analysis. The databases MEDLINE, Google Scholar, and Cochrane were consulted. We analyzed articles published between January 1978 and November 2018. From a total of 858 articles, 13 manuscripts were selected in this review. When animals exercised before experimental infarction, there was a reduction in mortality, a reduction in infarct size, improvements in cardiac function, and a better molecular balance between genes and proteins that exhibit cardiac protective effects. Analyzing heart weight/body weight, we observed the following results - Mean difference 95% CI - -0.02 [-0.61,0.57]. Meta-analysis of the infarct size (% of the left ventricle) revealed a statistically significant decrease in the size of the infarction in animals that exercised before myocardial infarction, in comparison with the sedentary animals -5.05 [-7.68, -2.40]. Analysis of the ejection fraction, measured by echo (%), revealed that animals that exercised before myocardial infarction exhibited higher and statistically significant measures, compared with sedentary animals 8.77 [3.87,13.66]. We conclude that exercise performed prior to experimental myocardial infarction confers cardiac benefits to animals.

Abstract Background: Neuromuscular electrical stimulation seems to be a promising option to intensify the rehabilitation and improve the exercise capacity of patients in the immediate postoperative period of cardiac surgery. Objective: This study aimed to evaluate the hemodynamic (heart rate, systolic blood pressure, diastolic blood pressure, and mean blood pressure) and respiratory (respiratory rate and oxygen saturation) responses to neuromuscular electrical stimulation in the immediate postoperative period in patients submitted to cardiac surgery and to verify its feasibility and safety. Methods: This is a pilot randomized controlled trial, wherein critical patients in the immediate postoperative period of cardiac surgery were randomly assigned to a control group, using sham neuromuscular electrical stimulation, or an experimental group, submitted to neuromuscular electrical stimulation sessions (FES), for 60 min, with a 50-Hz frequency, 200-µs pulse duration, time on: 3 s, and time off: 9 s. Data distribution was evaluated by the Shapiro-Wilk test. The analysis of variance was used and a p-value < 0.05 was considered significant. Results: Thirty patients were included in the study. The neuromuscular electrical stimulation was applied within the first 23.13 ± 5.24 h after cardiac surgery, and no changes were found regarding the hemodynamic and respiratory variables between the patients who underwent neuromuscular electrical stimulation, and those in the control group. Conclusions: In the present study, neuromuscular electrical stimulation did not promote changes in hemodynamic and respiratory responses of patients in the immediate postoperative period of cardiac surgery.

Abstract: The West Indian (Trichechus manatus) and Amazonian (T. inunguis) manatees have a sympatric occurrence at the mouth of the Amazon River. A result of this interspecific encounter is the occurrence of hybrids, which are frequently found along the coasts of Amapá state in Brazil, French Guiana and Guyana. Here we present new genetic evidence indicating the occurrence of a hybrid swarm along the Guianas Shield coastline, which is an interspecific hybrid zone that also separates T. manatus populations located east (Brazil) and west (Caribbean, Gulf of Mexico, Florida and Antilles). In addition, we suggest that this hybrid population occupies a peculiar mangrove-rich environment under strong influence of the Amazon River plume, which requires an independent management and should be considered a special conservation area.

RESUMO: O setor sementeiro está cada vez mais dinâmico e por isso demanda rápidas tomadas de decisões. O teste de tetrazólio é um teste rápido que determina a viabilidade das sementes, principalmente de espécies que apresentam germinação lenta ou dormência. A metodologia contida nas Regras para Análise de Sementes para a espécie Stylosanthes sp. não se aplica efetivamente para a espécie Stylosanthes capitata Vogel. Para adequar a metodologia de condução do teste de tetrazólio, foram utilizados três lotes de sementes de S. capitata com níveis de qualidade distintos. Na determinação da qualidade fisiológica das sementes, foram realizados os testes de germinação, primeira contagem da germinação, índice de velocidade de emergência, estandes inicial e final, condutividade elétrica, atividade respiratória e grau de umidade, além da curva de embebição para estabelecimento dos períodos de pré-embebição das sementes para a condução do teste de tetrazólio. Foram testados os períodos de pré-embebição e coloração, de 6, 12 e 18 h e, 3, 6, 12 e 24 h, nas concentrações de 0,075%, 0,1% e 0,5% da solução de tetrazólio. Concluiu-se que o período de 12 h de pré-embebição e 6 h de coloração na solução de tetrazólio a 0,1% é o ideal para a avalição da viabilidade de sementes de S. capitata.
Abstract: The seed sector is increasingly dynamic and therefore demands rapid decision-making. The tetrazolium test is a rapid test that determines the viability of seeds, especially from species that show slow germination or dormancy. The methodology described in the Rules for Seed Testing for Stylosanthes sp. is not applied effectively to the Stylosanthes capitata Vogel species. Three seed lots of S. capitata seeds with different quality levels were used to fit the tetrazolium test methodology. In order to determine the physiological quality of seeds, the tests of germination, first count germination, emergence speed index, initial and final seedling emergence percentage, electrical conductivity, respiratory activity and seed moisture content were performed, besides the imbibition curve for the establishment of pre-imbibition periods of the seeds to perform the tetrazolium test. The pre-imbibition and staining periods of 6, 12 and 18 h, and 3, 6, 12 and 24 h at concentrations of 0.075%, 0.1% and 0.5% tetrazolium solution were tested. It was concluded that the 12-h pre-imbibition period and 6-h staining at the 0.1% tetrazolium solution is ideal for evaluating the viability of S. capitata seeds.

RESUMO: As doenças dos cascos são as principais causas de claudicação em pequenos ruminantes, causando grande impacto no bem-estar dos animais e provocando sérias perdas econômicas com depreciação e abate de animais afetados. O objetivo do presente estudo foi determinar a ocorrência e caracterizar as doenças podais encontradas em oito rebanhos de ovinos com histórico de doenças podais pertencentes a oito municípios do estado da Bahia. Em cada visita, foram realizadas inspeções do rebanho, aplicação de um questionário de pesquisa e caracterização das doenças. No total, 600 ovinos foram inspecionados, realizando exame do casco em animais doentes para caracterizar as lesões, registrar a quantidade de doenças presentes por animal, o casco afetado e a quantidade de membros afetados. A ocorrência de doença de casco foi de 23,3% (140/600) variando de 12,8 a 55,5% por fazenda. Duzentos e vinte casos envolvendo nove doenças foram registrados. A pododermatite infecciosa foi a doença mais comum com 51,3% dos casos (113/220), 70% correspondente aos estágios avançados e terminais. A dermatite interdigital representou 27,7% dos casos; crescimento excessivo dos cascos 8,6%; doença da linha branca 3,2%; sola dupla 3,2%; granuloma do dígito 2,3%; hiperplasia interdigital 2,3%; úlcera de sola 0,9% e 0,4% de abcesso de pé. Os principais fatores predisponentes envolvidos na ocorrência das doenças foram a alta precipitação pluviométrica, condições de umidade do solo, currais e pastagens, manejo sanitário deficiente e falta de medidas preventivas (pedilúvio, quarentena, isolamento e vacinação), falhas de tratamento e baixa infra-estrutura da maioria das propriedades.
ABSTRACT: Foot diseases are the main causes of lameness in small ruminants, causing great impact on animal welfare and important economic losses due to depreciation and culling of affected animals. The aim of the present study was to characterize foot diseases found in eight flocks of sheep with a history of the ailment, that belonged to eight municipalities in the state of Bahia. At each visit, inspection of the flock, survey questionnaire, and characterization of diseases were performed. Altogether 600 sheep were inspected through foot examination in sick animals to characterize the injuries and record the diseases present per animal, as affected hooves and the number of affected limbs. The occurrence of foot disease was 23.3% (140/600) ranging from 12.8 to 55.5% per farm. Two hundred and twenty cases involving nine diseases were recorded. Foot rot was the most common disease with 51.3% of cases (113/220), 70% corresponding to advanced and terminal stages. Interdigital dermatitis represented 27.7% of the cases, excessive hoof growth 8.6%, white line disease 3.2%, double soles 3.2%, toe granuloma 2.3%, interdigital hyperplasia 2.3%, sole ulcers 0.9% and 0.4% foot abscess. The main predisposing factors involved in the genesis of diseases were the high rainfall precipitation, soil moisture conditions, pens and pastures, poor sanitary management and lack of preventive measures (footbath, quarantine, isolation and vaccination), treatment failures and low infrastructure of most properties.

The structures of two methoxylated chalcones, namely (E)-1-(4-methoxyphenyl)-3-(3,4,5-trimethoxyphenyl)prop-2-en-1-one and (E)-3-(4-ethoxyphenyl)-1-(4-methoxyphenyl)prop-2-en-1-one, reveal the effect of the inclusion of the methoxyl and ethoxyl substituents of the conformation on methoxy-chalcone. Structural comparative study between two chalcones was done in this work and some effects on geometric parameters, such as planarity and dihedral angles, were described. In addition, intermolecular interactions responsible for crystalline packaging were investigated by Hirshfeld surfaces and the values of those interactions were analysed by comparing experimental and theoretical models. The molecular stability was expressed in terms of softness and hardness, both obtained from frontier molecular orbitals. Finally, there is a good agreement between calculated and experimental infrared spectrum, which allowed the assignment of the normal vibrational modes.

RESUMO Inclui-se a doença de Ménétrier (DM) no grupo das gastropatias hipertóficas, sendo uma hiperplasia gástrica rara que acomete adultos e crianças, com comportamento distinto entre esses grupos. Sabemos que sua etiologia relaciona-se com alérgenos e coinfecções. Caracteriza-se pela hipertrofia das pregas gástricas, com aspecto de circunvoluções cerebrais à endoscopia digestiva alta (EDA) e, histologicamente, pelo alargamento da mucosa às custas de hiperplasia foveolar e hipotrofia das glândulas em corpo e fundo gástrico. A EDA, junto à biópsia gástrica, confirma o diagnóstico. O que nos intriga no caso a seguir é o tempo evolução arrastado da paciente, cerca de oito anos.
ABSTRACT Ménétrier's disease (MD) is included in the group of hypertrophic gastropathy; is a rare gastric hyperplasia that affects adults and children, with different behavior between these groups. We know that its etiology is related to allergens and co-infections. It's characterized by the hypertrophy of the gastric folds, with the appearance of cerebral convolutions on Upper Gastrointestinal Endoscopy (UGE) and, histologically, by the mucosal hypertrophy at the expense of foveolar hyperplasia and atrophy of the glands in body and fundus of the stomach. The UGE together with the gastric tissue biopsy confirms the diagnosis. What concerns us in the following case, however, is patient's long-lasting evolution, about eight years.

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.

A magnitude comparison deficit has been frequently observed in velocardiofacial syndrome (Del22q11.2). We hypothesized that this deficit extends to impairments in the acuity of the approximate number system (ANS). Three groups of children aged 8-14 years were investigated: Del22q11.2 children (n = 12), low cognitive ability children (LCA; n = 12), and matched typically developing children (TD; n = 28). All children were assessed with a simple reaction time task and symbolic and nonsymbolic number comparison tasks. To estimate the acuity of the ANS, the Weber fraction (w) was calculated from the nonsymbolic comparison task. The Del22q11.2 group exhibited a significantly higher w compared with the other groups. Importantly, no significant differences were found in w between the TD and LCA groups. The performance pattern of the Del22q11.2 group was similar to the TD group in the symbolic comparison task, and both of these groups had better performance than the LCA group. The impairment of ANS acuity observed in individuals with Del22q11.2 cannot be explained by deficits in general processing speed because no significant group differences were found in the simple reaction time task. These results suggest that lower acuity of the ANS should be added to the behavioral phenotype of Del22q11.2. The absence of impaired ANS acuity in the LCA group is consistent with the hypothesis that number sense is a relatively specific and autonomous domain. Investigations of low ANS acuity in mathematics learning difficulties and Del22q11.2 should be intensified.

Neste artigo realizou-se a avaliação de ovinos mestiços Santa Inês com pododermatite infecciosa, verificando as alterações no leucograma e proteínas de fase aguda. No primeiro experimento, 70 fêmeas foram separadas em três grupos de acordo com o seu escore podal: Grupo controle (G1) com escore 0; Dermatite interdigital (G2) com escore 1 ou 2 e Pododermatite necrosante (G3) com escore 3, 4 ou 5. Durante dois meses observou-se a evolução clínica e efeitos no leucograma em cinco momentos: M1 (dia 0), M2 (dia 15), M3 (dia 30), M4 (dia 45) e M5 (dia 60). A intensidade do resultado do leucograma foi de baixa magnitude, observando-se alterações significativas (p<0,05) como uma leve leucocitose (G3, M4), atribuída a neutrofilia e um discreto aumento no número total de monócitos (G3, M2 e M3) apesar do extenso dano e necrose tecidual existentes na última fase da doença. No segundo experimento, utilizaram-se 105 animais de sete propriedades com objetivo de isolar o agente etiológico e avaliar os efeitos da doença sobre proteína plasmática total e proteínas de fase aguda. Os animais também foram separados em três grupos: controle, dermatite interdigital e pododermatite necrosante. Em todas as propriedades foi realizado o isolamento de Dichelobacter nodosus. Não houve correlação significativa (p<0,05) das diferentes fases da doença sobre as proteínas estudadas, porém a haptoglobina dos grupos com animais doentes apresentou médias superiores ao grupo controle. De acordo com a metodologia utilizada e resultados obtidos, conclui-se que as proteínas de fase aguda estudadas não foram eficientes na caracterização das fases da pododermatite infecciosa ovina e que a resposta leucocitária foi branda, tornando difícil sua utilização para este fim.
In this paper, Santa Inês crossbred sheep with footrot were evaluated, checking the changes on leukogram and the acute phase proteins. In the first experiment, 70 females were divided into three groups according to their podal scores: a control group (G1) with score 0, scald group (G2) with score 1 or 2 and a footrot group (G3) with score 3, 4 or 5. During two months, the clinical course and its effect on leukogram were observed at five moments: M1 (day 0), M2 (day 15), M3 (day 30), M4 (day 45) and M5 (day 60). The intensity of the white blood cell count was low magnitude, observing significant changes (p <0.05) as a mild leukocytosis (G3, M4), attributed to neutrophilia and a slight increase in the total number of monocytes (G3, M2 and M3) despite the extensive damage and tissue necrosis existed during the final stage of the disease. In the second experiment, 105 animals from seven farms were used with the objective of isolating the causative agent and to evaluate the effect of disease on total plasma protein and acute phase proteins. The animals were also divided into three groups: control, scald and footrot. In all farms, the isolation of Dichelobacter nodosus was regarded. For the different stages of the disease on the proteins studied there was no significant correlation (p<0.05) but the haptoglobin in scald and footrot groups showed higher average than the control group. Based on these results, we conclude that the acute phase proteins studied were not efficient in the characterization of the phases of the disease and the leukocyte response was mild, making it difficult to use for this purpose.
