ABSTRACT The objective of this study was to evaluate the effect of irrigation with low- and high-salinity water on the increment of salts in the soil, the production components of sour passion fruit and the leaching of salts by rainfall and by leaching fraction of 10%. The treatments were arranged in randomized blocks, in a split-plot scheme, corresponding to three irrigation management practices [evaluation of soil chemical attributes before irrigation; and after irrigation with water of low electrical conductivity (0.35 dS m-1), and high electrical conductivity (4.00 dS m-1) in the main plot], and in the subplot two soil depths of evaluation (0-20 and 20-40 cm) and three soil sampling times (at 115 days after transplanting of seedlings (DAT) - beginning of flowering; at 199 DAT - end of the dry season; and at 379 DAT - end of the rainy season). Irrigation increased the electrical conductivity of the soil saturation extract, with higher values in the surface layer and at the end of the dry season. Rainfall during the rainy season reduced the saline character of soil from moderately saline and strongly saline, in treatments irrigated with water of low and high electrical conductivity, to non-saline and slightly saline, respectively. Irrigation with high-electrical conductivity water negatively affected the production components and yield of sour passion fruit.
RESUMO O objetivo deste estudo foi avaliar o efeito da irrigação com água de baixa e alta salinidade sobre o incremento de sais no solo, os componentes de produção do maracujazeiro azedo e a lixiviação dos sais pela precipitação pluviométrica e pela fração de lixiviação de 10%. Os tratamentos foram dispostos em blocos ao acaso, em esquema de parcelas subdivididas, correspondendo a três práticas de manejo de irrigação [avaliação dos atributos químicos do solo antes da irrigação; e após irrigação com água de baixa (0,35 dS m-1) e alta condutividade elétrica (4,00 dS m-1) na parcela principal], e na subparcela duas profundidades de avaliação dos atributos químicos do solo (0-20 e 20-40 cm) e três épocas de amostragem de solo (aos 115 dias após o transplantio das mudas (DAT) - início do florescimento das plantas; aos 199 DAT - final do período de estiagem; e aos 379 DAT - final do período chuvoso). A irrigação elevou a condutividade elétrica do extrato de saturação do solo, com superioridade na camada superficial e no final do período seco. A precipitação pluviométrica durante a estação chuvosa reduziu o caráter salino do solo de medianamente e fortemente salino, nos tratamentos irrigados com água de baixa e alta condutividade elétrica, para não salino e ligeiramente salino, respectivamente. A irrigação com água de alta condutividade elétrica afetou negativamente os componentes de produção e produtividade do maracujazeiro azedo.

Abstract Low density sugarcane plantation (LDSP) has been implemented by some sugarcane producers in Brazil, aiming to save seeds and operational costs. The study was carried out in the municipality of Areia, Paraíba, Brazil. Five planting densities were used, varying from 5 to 25 m-2 of buds arranged in randomized blocks, with four replications. Data were measured annually over three cultivation cycles (2017 to 2020), during which the field was fertilized with NPK and the harvests were carried out manually without prior burning. The lower planting density presents higher productivity only in the cane plant (101.03 t ha-1) due to the higher plant height (2.37 m) and the higher number of stalks (11 stalks m-2), suggesting that these variables are due to the greater availability of light, water and photosynthate. However, there is a drastic reduction in sugarcane yield for this lower population in the 2nd ratoon by up to 65.62%, which is correlated with number of stalks per meter. We demonstrate the agronomic viability of LDSP in the population of 10 buds m-2 in relation to conventional planting of sugarcane until the 2nd ratoon. Data are important for future studies to present additional considerations for other production factors, such as the effects of mechanized harvesting and the management of nutrients and water, assessing the sustainability of this large-scale planting system.
Resumo O método de plantio de cana-de-açúcar de baixa densidade (LDSP) vem sendo implementado por alguns produtores de cana-de-açúcar no Brasil, visando economia de sementes e custos operacionais. O estudo foi realizado no município de Areia, Paraíba, Brasil. Utilizou-se cinco densidades de plantio, variando de 5 a 25 m-2 de gemas dispostas em blocos casualizados, com quatro repetições. Os dados foram medidos anualmente ao longo de três ciclos de cultivo (2017 a 2020). Menor densidade de plantio mostrou maior produtividade (101,03 t ha-1) devido à maior altura de planta (2,37 m) e ao maior número de hastes (NS) (11 hastes m-2), sugerindo que essas variáveis são devido à maior disponibilidade de luz, água e fotoassimilados. No entanto, houve redução drástica na produtividade da cana-de-açúcar para esta população menor na 2ª soca em 65,62%, estando correlacionado com o número de colmos por metro. Demonstramos a viabilidade agronômica do LDSP em uma população de 10 gemas m-2 em relação ao plantio convencional de cana-de-açúcar até a 2ª soca. Os dados são importantes para que estudos futuros apresentem considerações adicionais sobre outros fatores de produção, como os efeitos da colheita mecanizada e do manejo de nutrientes e água, avaliando a sustentabilidade desse sistema de plantio em larga escala.

ABSTRACT Objectives: Currently, not much is known about the interactions between voice and growth hormone (GH). We have described large kindred with isolated GH deficiency (IGHD) due to a GHRH receptor mutation, resulting in severe short stature and high-pitched voice. These IGHD individuals have little interest in GH treatment, as they consider themselves “short long-lived people”, rather than patients. Interestingly, they report normal general quality of life, but they rate their Voice-Related Quality of Life (V-RQOL) as low. Here, we assessed the social and auditory-perceptual impacts of artistic-intervention voice therapy with semioccluded vocal tract exercises (SOVTE) and choral singing, on their voices. Material and methods: Seventeen GH-naïve adult IGHD individuals were enrolled in a single-arm interventional pre-post study with 13 weekly sessions of choir singing over 90 days. Outcome measures were V-RQOL scores, self-assessment of voice, and auditory-perceptual analysis (GRBAS scale, G: grade of the severity of dysphonia; R: roughness; B: breathiness; A: asthenia; and S: strain). Results: Marked improvements in total (p = 0.0001), physical (p = 0.0002), and socioemotional (p = 0.0001) V-RQOL scores and in self-assessment of voice (p = 0.004) were found. The general grades of vocal deviation (p = 0.0001), roughness (p = 0.0001), breathiness (p = 0.0001) and strain (p = 0.0001) exhibited accentuated reductions. Conclusions: Voice therapy with semioccluded vocal tract exercises and choral training improved social impact and perceptual voice assessments in IGHD subjects and markedly improved their voice-related quality of life. This is particularly important in a setting where GH replacement therapy is not widely accepted.

RESUMO Objetivou-se avaliar os parâmetros bioquímicos de caprinos submetidos ou não a castração e recebendo ou não suplementação com vitamina E. Um total de 24 caprinos, machos não castrados (12 unidades experimentais) e machos castrados (12 unidades experimentais), com peso corporal médio de 17,6 kg ± 2,67 kg, foram distribuídos em delineamento inteiramente casualizado em arranjo fatorial 2 x 2, sendo duas condições animais (macho castrado e não castrado) e suplementação com vitamina E (com e sem suplementação), com seis repetições. Houve efeito dos tratamentos (P<0,05) ao longo do tempo para todas as variáveis estudadas. Houve efeito da suplementação vitamínica (P<0,05) para fósforo, ferro, proteína, glicose, aspartato aminotransferase (AST), alanina aminotransferase (ALP) e gama-glutamiltransferase (GGT). A suplementação vitamínica elevou os níveis de glicose, creatinina e GTT ao longo do tempo, e reduziu os níveis de fósforo, ferro, proteína, albumina, AST e ALP. Concluímos que a vitamina E influenciou nos parâmetros bioquímicos estudados, porém a castração não alterou o perfil bioquímico de caprinos, independentemente de estarem suplementados ou não com a vitamina E.
ABSTRACT The objective of this study was to evaluate the biochemical parameters of goats submitted to castration or not and receiving supplementation with vitamin E or not. A total of 24 goats, uncastrated (12 experimental units) and castrated males (12 experimental units), with average body weight weighing 17.6 kg ± 2.67 kg, were distributed in a completely randomized design in a 2 x 2 factorial arrangement, with two animal conditions (castrated and uncastrated male) and vitamin E supplementation (with and without supplementation), with six replications. There was an effect of treatments (P<0.05) over time for all studied variables. There was an effect of vitamin supplementation (P<0.05) for phosphorus, iron, protein, glucose, aspartate aminotransferase (AST), alanine aminotransferase (ALP) and gamma-glutamyltransferase (GGT). Vitamin supplementation increased glucose, creatinine and GTT levels over time, and reduced levels of phosphorus, iron, protein, albumin, AST and ALP. We conclude that vitamin E influenced the biochemical parameters studied, but castration did not change the biochemical profile of goats, regardless of whether they were supplemented with vitamin E or not.

Abstract This work reports the evaluation of the microstructure, morphology, and catalytic behavior of α-Al2O3 synthesized via combustion method for esterification reaction of oleic acid in soybean oil with ethanol to produce biodiesel. The reaction was evaluated with 2 wt% of catalyst at 160 °C for 3 h when the molar ratio of fatty acid:ethanol was 1:12. To enhance the catalytic performance of α-Al2O3, its sulfation was done by a different method using mechanical milling. The microcatalysts were characterized by X-ray diffraction, Fourie transform infrared spectroscopy, granulometric analysis, and scanning electron microscopy. Results showed α-Al2O3 as the major phase, presence of SO4 2- groups, the contribution of the sulfation process to morphology with reduction of agglomerates, and particle size from 18.98 to 15.30 mm. The yield of ester was enhanced from 80% (α-Al2O3 as a catalyst) to 93% (SO4 2-/α-Al2O3 as a catalyst), which showed the milling as a fast method for synthesis of a highly efficient acid catalyst to produce biodiesel.

RESUMO A baixa fertilidade do solo associada à falta de manejo adequado da irrigação são fatores que mais limitam a produção das culturas. Diante disso, objetivou-se avaliar os atributos químicos de um Oxisol e a produtividade da goiabeira ‘Paluma’ sob irrigação com água salina e adubada com fósforo, esterco bovino e boro. Os tratamentos foram distribuídos em blocos ao acaso, com quatro repetições e duas plantas por parcela, incluindo bordaduras nas laterais da área útil experimental, utilizando um esquema fatorial de (5 × 2) + 1, referentes a cinco doses de fósforo (0, 0.08, 0.16, 0.24 e 0.32 kg de P2O5 planta-1), duas doses de esterco bovino, 0 e 30 kg por planta e um tratamento adicional composto por 0.16 kg de P2O5 mais 30 kg de esterco bovino e 1.0 g de boro, utilizando como fonte o bórax. No solo avaliaram-se pH, fósforo, potássio, cálcio, magnésio e a capacidade de troca catiônica nas camadas de 0-20 cm e de 20-40 cm. Nas plantas, estimou-se a produtividade média por hectare em duas safras. O pH diminuiu com as doses de fósforo sem esterco bovino e no tratamento com boro na camada de 20-40 cm. A capacidade de troca catiônica aumentou com aplicação das doses de fósforo associadas ao esterco e diminuiu nas duas camadas do solo com a presença do boro. Os macronutrientes avaliados não foram influenciados pelo boro. As doses de fósforo associadas ao esterco bovino aumentaram a produtividade superando a média de 50 t ha-1 ano-1 determinada para a goiabeira ‘Paluma’, enquanto que o boro não aumentou a produtividade.
ABSTRACT The low soil fertility associated with the lack of adequate irrigation management are factors that most limit crop production. Therefore, the study aimed to evaluate the chemical attributes of an Oxisol and the yield of ‘Paluma’ guava under irrigation with saline water and fertilized with phosphorus, cattle manure, and boron. The treatments were distributed in randomized blocks, with four repetitions and two plants per plot, including borders on the sides of the useful experimental area, arranged in a factorial scheme (5 × 2) + 1, referring to five phosphorus doses (0, 0.08, 0.16, 0.24 and 0.32 kg of P2O5 plant-1), two doses of cattle manure, 0 and 30 kg per plant and an additional treatment consisting of 0.16 kg of P2O5 plus 30 kg of cattle manure and 1.0 g of boron, using as source the borax. In the soil, pH, phosphorus, potassium, calcium, magnesium, and the cation exchange capacity were evaluated in the 0-20 cm and 20-40 cm layers. In plants, the average yield per hectare in two harvests was estimated. The pH decreased with phosphorus doses without cattle manure and in the treatment with boron in the 20-40 cm layer. The cation exchange capacity increased with the application of phosphorus doses associated with manure and decreased in both soil layers with boron. The macronutrients evaluated were not influenced by boron. Phosphorus doses associated with cattle manure increased yield, exceeding the average of 50 t ha-1 year-1 determined for ‘Paluma’ guava. In contrast, boron did not increased the yield.

Visceral adipose tissue (VAT) is associated with various metabolic disorders, and adipokines, secreted by adipose tissue, are involved in their pathogenesis. This study investigated associations between VAT/subcutaneous adipose tissue (SAT) ratio, inflammatory markers, and cardiovascular (CV) risk-score in adults. Plasma levels of adipokines, plasma lipid profile, blood pressure, and body composition (using dual-emission x-ray absorptiometry) were determined. CV risk-score based on the American College of Cardiology and the American Heart Association (ACC/AHA) score was calculated in a sample of 309 Brazilian civil servants aged <60 years. Participants' VAT/SAT ratio were categorized into quartiles. Among males, plasma leptin (2.8 ng/mL) and C reactive protein (CRP) (0.2 mg/dL) (P<0.05) levels were higher at P75 and P50 than P5, and the highest calculated CV risk-score was observed at P75 (7.1%). Among females, higher plasma adiponectin levels were observed at P25 (54.3 ng/mL) compared with P75 (36 ng/mL) (P<0.05). Higher plasma CRP levels were observed at P75 (0.4 mg/dL) compared with P5 (0.1 mg/dL) (P<0.05). Higher CV risk-score was observed at P75 (2.0%) compared with P5 (0.7%). In both sexes, VAT and VAT/SAT ratio were directly associated with plasma leptin, CRP, and CV risk-score, and inversely associated with adiponectin; SAT was directly associated with plasma leptin and CRP (P<0.01); interleukin (IL)-10 and CRP were directly associated with adiponectin and leptin, respectively (P<0.05). Among men only, IL-10 (inversely) and CRP (directly) were associated with CV risk-score (P=0.02). Our results strengthened the relevance of the VAT/SAT ratio in cardiovascular risk.

Abstract Carbapenem-resistant P. aeruginosa (CRPA) has become a serious public health problem and the biofilm formation aggravates this problem. The study aimed to evaluate the occurrence of β-lactamases and quorum sensing (QS) genes in CRPA isolates, analyze production of biofilm, evaluate the response against meropenem (MPM) and∕or polymyxin B (POL B) and its association with azythromicin (AZT) using quantum dots (QDs) and proteomic analysis. Six CRPA isolates were analyzed. β-lactamases and QS genes were search using specific PCRs and were tested for biofilm production by quantitative technique. A CRPA isolate, containing blaKPC gene and biofilm-producing, was selected to assess its response to therapy using QDs and the MALDI-TOF. The β-lactamase detected was blaKPC in 66.7% of the isolates. All isolates were biofilm producers and carriers of the QS genes. QDs-MPM conjugates triggered the formation of biofilm and the association with AZT inhibited this effect. Proteomics analysis showed that treatments with MPM or POL B suppressed the expression of the transglycosylase protein, while combined therapy with AZT induced expression of the RpoN protein. Thus, this study shows that the use of fluorescence combined with the proteomics analysis was promising to understand how a CRPA strain reacts to antimicrobial treatment.

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.

Objective: To evaluate body dissatisfaction and distorted body self-image in women with prolactinoma. Methods: Body dissatisfaction and distorted body self-image were evaluated in 80 women with prolactinoma. All patients were in menacme, 34% had normal body mass index (BMI), and 66% were overweight. Most patients (56.2%) had normal prolactin (PRL) levels and no hyperprolactinemia symptoms (52.5%). The Body Shape Questionnaire (BSQ) was used to assess the patients’ dissatisfaction with and concern about their physical form, and the Stunkard Figure Rating Scale (FRS) was used to assess body dissatisfaction and distorted body self-image. The patients were divided according to PRL level (normal vs. elevated) and the presence or absence of prolactinoma symptoms. Results: The normal and elevated PRL groups had similar incidences of body dissatisfaction and distorted body self-image. However, symptomatic patients reported a higher incidence of dissatisfaction than asymptomatic patients. Distorted body self-image was less common among symptomatic patients. Conclusion: Symptomatic patients showed higher body dissatisfaction, but lower body self-image distortion. The presence of symptoms may have been responsible for increased body awareness. The perception of body shape could have triggered feelings of dissatisfaction compared to an ideal lean body. Therefore, a distorted body self-image might not necessarily result in body dissatisfaction in women with prolactinomas.

Objetivou-se avaliar o efeito protetor do óxido nítrico durante a germinação e vigor de sementes e desenvolvimento de plântulas de Eucalyptus urophylla sob condições de estresse salino. O delineamento foi inteiramente casualizado, com cinco repetições, em esquema fatorial 3 x 3 + 1, sendo três condicionantes (água, nitroprussiato de sódio - SNP e nitrato de potássio), três condições de germinação (água destilada, e os potenciais de -0,6 e -1,2 MPa), tendo como tratamento adicional, o controle (semente não condicionada). Determinou-se: contagem da germinação aos sete e quatorze dias, índice de velocidade de germinação, comprimento da raiz primária, de parte aérea e total. O SNP protege as sementes possibilitando maior porcentagem de germinação, assim como promove maior crescimento de raiz e tamanho total de plântula, já o KNO3 não é eficaz protegendo as sementes, as quais sofrem com estresse salino, o que afeta suas características fisiológicas e morfológicas. Sementes de E. urophylla são sensíveis ao estresse salino e o condicionamento fisiológico com SNP promove o aumento da porcentagem de germinação, vigor e desenvolvimento de plântulas sob condições de salinidade.
Abstract: The germination response of seeds under artificial stress conditions is a tool for better understanding of the survival and adaptation ability of species under natural stress conditions. The aims of this study were to evaluate the protective effect of nitric oxide during germination as well as seed vigor and seedling development of Eucalyptus urophylla under salt stress conditions. The experimental design was completely randomized, with five replications, in a 3 × 3 + 1 factorial arrangement, with three priming factors [water, sodium nitroprusside (SNP), and potassium nitrate (KNO3)], three germination conditions (distilled water, and the water potentials of -0.6 and -1.2 MPa), and an additional control treatment (unprimed seeds). The following determinations were made: germination count at seven and fourteen days, germination speed index, primary root length, shoot length, and total length. SNP protects seeds, leading to a higher percentage of germination, as well as greater root growth and total seedling size, whereas KNO3 is not effective in protecting seeds that suffer from salt stress, which affects their physiological and morphological characteristics. E. urophylla seeds are sensitive to salt stress, and physiological priming with SNP leads to an increase in the percentage of germination, vigor, and seedling development under salinity conditions.

Abstract The anatomy of wood and charcoal was analyzed by scanning electron microscopy in three radial positions of E. urophylla and E. Grandis in different diameter classes at six years. The carbonization process was given in the muffle with an average rate of 0.5 °C increment per minute, using initial temperature of 150 °C and maximum of 450 °C. It was observed that the pore diameter presented higher values in the samples obtained in the internal position. The diameter classes of the trees almost did not influence the characteristics of the fibers. In the external position (close to the shell) fibers with higher values of cell wall thickness and smaller values of lumen diameter and width were identified. The fiber lumen diameter was not affected by the wood carbonization process, whereas the cell wall thickness and fiber width were reduced.

RESUMO O açaizeiro solteiro vem sendo demandado devido às características funcionais dos frutos e, por isso, seu plantio tem sido incentivado. Todavia, não há informações acerca do sistema de produção da muda, bem como não estão definidos o ambiente adequado e nem a quantidade de adubo que possa compor o substrato, a fim de formar uma muda sadia e vigorosa. Objetivou-se avaliar o efeito de ambientes e doses de fertilizante de liberação lenta na produção de mudas de açaizeiro. Utilizou-se delineamento em blocos casualizados, com três repetições e dez plantas por parcela. Os tratamentos foram arranjados em esquema fatorial 4 x 5, sendo quatro ambientes (20 %, 30 %, 50 % e 75 % de sombra) e cinco doses de fertilizante de liberação lenta (0,0 kg m-3; 2,5 kg m-3; 5,0 kg m-3; 7,5 kg m-3; e 10,0 kg m-3 de substrato). Foram analisados a altura da muda; diâmetro do coleto; número de folhas; massa seca das folhas, do estipe, das raízes e total; e o índice de qualidade de mudas. Houve interação significativa entre os ambientes de sombra e as doses de adubo de liberação lenta para todas as variáveis analisadas. O ambiente com 75 % de sombra proporciona mudas de melhor qualidade. O fertilizante de liberação lenta pode ser utilizado para a produção de mudas de açaizeiro solteiro em ambientes com 50 % e 75 % de sombra, sendo as doses de 4,60 kg m-3 e 8 kg m-3, respectivamente, as mais indicadas.
ABSTRACT Euterpe precatoria Mart. has been demanded due to the functional characteristics of its fruits and, therefore, its planting has been encouraged. However, there is a lack of information about the seedling production system of this palm tree. Neither a favorable environment nor the amount of fertilizer in the substrate have been defined for the production of healthy and vigorous seedlings. This study aimed to evaluate the effect of environments and doses of a slow-release fertilizer on the production of E. precatoria seedlings. The experiment was conducted in a randomized block design, with three replications and ten plants per plot. The treatments were arranged in a 4 x 5 factorial scheme, with four environments (under shading levels of 20 %, 30 %, 50 % and 75 %) and five doses of a slow-release fertilizer (0.0 kg m-3, 2.5 kg m-3, 5.0 kg m-3, 7.5 kg m-3 and 10.0 kg m-3 of substrate). The seedling height; root collar diameter; number of leaves; leaf, shoot, root and total dry mass; and the Dickson quality index were analyzed. There were significant interactions between the shaded environments and slow-release fertilizer doses for all the analyzed variables. The 75 %-shaded environment yielded better quality seedlings. The slow-release fertilizer can be used to produce E. precatoria seedlings in environments under shading levels of 50 % and 75 %, being the 4.60 kg m-3 and 8 kg m-3 doses, respectively, the most recommended ones.

Resumo A diarreia neonatal determina alterações significativas na conversão alimentar, resultando na queda da produtividade de caprinos. A resistência antimicrobiana em bactérias caracteriza-se como importante problema de saúde pública, assim, a Escherichia coli pode ser caracterizada como importante patógeno por expressar mecanismos de virulência responsáveis por significativas afecções clínicas em seres humanos e animais. O presente estudo avaliou a presença de E. coli em 117 amostras fecais de caprinos e analisou a resistência antimicrobiana dos isolados. Colônias sugestivas foram submetidas a testes bioquímicos, seguido de determinação do grupo genotípico e análise filogenética; posteriormente foram submetidas à prova de suscetibilidade a antimicrobianos. Foram identificados isolados de E. coli, Salmonella spp, Shigella sonnei e Enterobacter aerogenes. Isolados de E. coli foram classificados filogeneticamente em B2 (9/39), D (19/39), B1 (7/39) e A (4/29). Os fatores de virulência identificados foram K99 (04/39) e Stx (02/39). À prova de suscetibilidade antimicrobiana, os isolados foram sensíveis a Cloranfenicol, Estreptomicina, Amoxicilina e Ciprofloxacina, sendo todos resistentes à Lincomicina, Vancomicina e Penicilina. Os resultados reforçam a necessidade de estabelecimento de protocolos criteriosos para o uso de antimicrobianos, medida fundamental para o aprimoramento da sanidade dos rebanhos caprinos brasileiros.
Abstract Neonatal diarrhea determines significant changes in feed conversion, causing productivity loss in caprine herds. The antimicrobial resistance in bacteria is characterized as an important public health issue; therefore, Escherichia coli may be characterized as an important pathogen due to expressing virulence mechanisms responsible for significant clinical conditions in humans and animals. The present study evaluated the presence of E. coli among 117 caprine fecal samples and analyzed the isolates for antimicrobial resistance. Suggestive colonies were submitted to biochemical screening followed by genotypic group determination and phylogenetic analysis; further, the samples were submitted to antimicrobials susceptibility test. E. coli, Salmonella spp, Shigella sonnei and Enterobacter aerogenes were identified. E. coli isolates were phylogenetically classified as B2 (9/39), D (19/39), B1 (7/39) e A (4/29) groups. The analysis of the isolates also revealed the presence of K99 (04/39) and Stx (02/39) virulence factors. Antimicrobial susceptibility test revealed sensitive isolates to Chloramphenicol, Streptomycin, Amoxicillin and Ciprofloxacin, being all resistant to Lincomycin, Vancomycin and Penicillin. The results support the need of establishing restricted protocols for antimicrobial use, a fundamental procedure for health improvement in Brazilian caprine herds.

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.
