ABSTRACT: Laminitis is a disease that affects the dermis and epidermis of the bovine hoof, generating changes in the hoof capsule. This study evaluated the effects of clinical laminitis diagnosed after the adaptation phase to confinement on the morphology, density, and mineral composition of the hoof of Nellore cattle after finishing. The animals were separated in the first weeks of confinement into a sick group (SG), with clinical laminitis, and a healthy group (HG). SG animals had higher heel length, dorsal wall length, toe height, and diagonal hoof length (p<0.05) than healthy animals. The dermal laminae had similar measurements for thickness, length, and spacing between them between SG and HG. Animals with laminitis showed congestion, hemorrhage, and basement membrane irregularities on histology. Computed microtomography (μCT) revealed that the hoof density of sick animals is lower than healthy ones. According to the mineral composition by energy-dispersive X-ray fluorescence (ED-XRF) spectrometry, the hooves of animals with laminitis (SG) and healthy ones (HG) were not biochemically different. Therefore, the occurrence of clinical laminitis in Nellore cattle in the first weeks of confinement causes an increase in the morphometric parameters of the hoof capsule and a reduction in the density of the abaxial hoof wall evaluated after the finishing period. This disease does not promote changes in the histomorphometric parameters of the dermal laminae and the percentage of minerals in the abaxial hoof wall.

RESUMO: A laminite é uma doença que afeta a derme e epiderme do casco de bovinos gerando alterações no estojo córneo. O estudo avaliou os efeitos da laminite clínica diagnosticada após a fase de adaptação ao confinamento na morfologia, densidade e composição mineral do casco de bovinos da raça Nelore após terminação. Nas primeiras semanas de confinamento, os animais foram separados em um grupo doente (GD) com laminite clínica e em um grupo saudável (GS). Os animais do GD apresentaram maior comprimento de talão, comprimento da parede dorsal, altura da pinça e comprimento diagonal do casco (p<0,05) do que os saudáveis. As lâminas dérmicas tiveram medidas semelhantes para espessura, comprimento e espaçamento entre elas entre GD e GS. Animais doentes apresentaram congestão, hemorragia e irregularidades da membrana basal na histologia. A microtomografia computadorizada (μCT) revelou que a densidade do casco de animais doentes é menor do que o saudável. Para a composição mineral por meio da espectrometria de fluorescência de raio-X por dispersão de energia (ED-XRF), o casco dos animais doentes (GD) e dos saudáveis (GS), não se mostraram diferentes bioquimicamente. Conclui-se que a ocorrência de laminite clínica em bovinos da raça Nelore nas primeiras semanas de confinamento ocasiona aumento de parâmetros morfométricos do estojo córneo e redução da densidade da parede abaxial do casco, avaliados após o período de terminação. Essa enfermidade não promove modificações nos parâmetros histomorfométricos das lâminas dérmicas e na porcentagem de minerais da parede abaxial do casco.

SUMMARY We report a rare case of Cushing’s syndrome in a 37-year-old female who initially presented with localized acinic cell carcinoma of the parotid gland. In January 2014, she underwent a right parotidectomy with facial nerve preservation and adjuvant radiotherapy. In August 2018, she presented a histologically-proven local regional relapse. The patient was considered for salvage surgery with facial nerve sacrifice and remained with no evidence of disease. One year later the patient developed pulmonary dissemination and started to gain weight and developed facial plethora and acne on the face and upper trunk. In a physical examination, the patient presented moon face, buffalo hump, acne and stage 2 hypertension. Biochemical evaluation confirmed ACTH-dependent Cushing’s syndrome. IHC for ACTH in the lung biopsy revealed strong positive staining for ACTH confirming a diagnosis of ectopic ACTH secretion by a metastatic parotid acinic cell carcinoma. Ketoconazole (600 mg/d) was started to treat the CS. In addition, as chemotherapy was initiated to treat the metastatic disease. After the fifth cycle of chemotherapy, ketoconazole was suspended and the patient remained in remission of CS for four months, when CS recurred. A unique feature of this case is related to the clinical CS relapse associated with disease progression, which needed prompt treatment with ketoconazole, resulting in a significant improvement in the patient’s condition. Although rare, should be attentive for possible CS features in patients with high-grade salivary gland carcinomas, since the diagnosis of ectopic secretion of ACTH may significantly impact their management and outcomes.

ABSTRACT The Atlantic Forest is made up of different vegetation types over extensive latitude. Most of its remnants are in mountain ranges, which are responsible for the maintenance of most endemic and threatened species in this domain. Here we present the floristic composition of the Área de Proteção Ambiental Mestre Álvaro (APAMA), a coastal massif at Espírito Santo State with expressive altitudinal amplitude (100-800 a.s.l.) containing remnants never floristically studied. Knowing the composition of this protected area is important because it includes an altitudinal range not yet evaluated in floristic comparisons involving highland and lowland forests between the latitudes 18-21° S. We found 493 species (in 292 genera and 91 families): ten are regional endemic species, nine are new records of occurrence for the state, and 52 are under some degree of threat of extinction. Our results indicate the presence of flora elements' typical of both highland and lowland forests, which makes the APAMA essential in a scenario extremely fragmented. Finally, our data provide an unprecedented floristic list for regional forest restoration projects, as well as an invaluable source of data for biogeographic studies that seek to understand the effect caused by neighboring vegetation types on the composition of lowland forests.

ABSTRACT. Fig tree (Ficus carica L., Moraceae), which originated in the Mediterranean Basin, is one of the many fruit trees grown in Brazil, with ‘Roxo-de-Valinhos’ being the exclusively used cultivar. In this context, research aimed at the improvement of this species to develop highly resistant and adaptable cultivars is paramount. Thus, the present study aimed to maintain fig accessions in an in vivo active germplasm bank (AGB) at the Faculty of Engineering of Ilha Solteira (FEIS), São Paulo State University (UNESP), as well as to characterize the agronomic traits of these accessions based on quantitative descriptors of genetic parameters and observe gains with the selection of specific genotypes to illustrate the AGB in terms of genetic variability. A total of 36 F. carica genotypes were evaluated in the field at the Teaching, Research and Extension Farm (FEPE) of the FEIS, UNESP. Qualitative traits, fruit parameters (e.g., insertion of the first fruit, fruit stalk length, fruit length, fruit diameter, and average fruit mass), and accumulated plant dry mass were measured. In addition, genetic parameters, variance components, and descriptive statistics, including genetic and environmental variances, heritability and average heritability of clones, coefficients of genotypic and environmental variation and their ratio (CV g %/Cv e %), general average, and selection gain, were evaluated. The selected fig tree accessions showed genetic variability in the assessed traits, exhibiting good heritability and achieving selection gains. For instance, the first 10 classified clones exhibited a heritability of 80.2% and achieved a selection gain of 98% for accumulated plant dry mass. Therefore, the maintenance of in vivo AGBs allows agronomic studies, offering promising results for continuing the breeding programs and preserving the genetic variability of species.

Abstract This study aims to evaluate the in silico genomic characteristics of Streptococcus infantarius subsp. infantarius, isolated from Coalho cheese from Paraíba, Brazil, with a view to application in lactic fermentations. rRNA sequences from the 16S ribosomal region were used as input to GenBank, in the search for patterns that could reveal a non-pathogenic behavior of S. infantarius subsp. infantarius, comparing mobile genetic elements, antibiotic resistance genes, pan-genome analysis and multi-genome alignment among related species. S. infantarius subsp. infantarius CJ18 was the only complete genome reported by BLAST/NCBI with high similarity and after comparative genetics with complete genomes of Streptococcus agalactiae (SAG153, NJ1606) and Streptococcus thermophilus (ST106, CS18, IDCC2201, APC151) revealed that CJ18 showed a low number of transposases and integrases, infection by phage bacteria of the Streptococcus genus, absence of antibiotic resistance genes and presence of bacteriocin, folate and riboflavin producing genes. The genome alignment revealed that the collinear blocks of S. thermophilus ST106 and S. agalactiae SAG153 have inverted blocks when compared to the CJ18 genome due to gene positioning, insertions and deletions. Therefore, the strains of S. infantarius subsp. infantarius isolated from Coalho cheese from Paraíba showed genomic similarity with CJ18 and the mobility of genes analyzed in silico showed absence of pathogenicity throughout the genome of CJ18, indicating the potential of these strains for the dairy industry.

Resumo A variabilidade dos organismos em uma determinada área constitui o que se denomina biodiversidade, uma das propriedades fundamentais da natureza, responsável pelo equilíbrio e estabilidade dos ecossistemas. A perda da biodiversidade tem sido uma grande preocupação para os cientistas, principalmente pelo papel desempenhado pelas atividades humanas, com potencial para desencadear circunstâncias irreversíveis. A Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP) desempenha um papel importante no apoio às pesquisas nos mais diversos ramos da ciência. No final da década de 1990, a FAPESP lançou um grande programa de fomento à pesquisa em biodiversidade, denominado BIOTA/FAPESP. Até o momento, este programa financiou a realização de 26 projetos, envolvendo atividades na maior parte do Brasil, embora tenham como foco principal o estado de São Paulo. Esses projetos geraram cerca de 1.140 publicações em periódicos de alto impacto, fornecendo informações relevantes que incluem a descrição original de 1.187 espécies e 76 gêneros e a descrição complementar de 350 espécies, além de diversos trabalhos de inventário, estudos biológicos etc. O programa também tem sido fundamental para o estabelecimento ou adequação de instalações de pesquisa científica e o treinamento de novos taxonomistas. Os grupos de invertebrados terrestres mais estudados incluem os Insecta das ordens Hymenoptera, Lepidoptera e Diptera, e os Arachnida das subclasses Araneae e Acari. Projetos distintos também têm contribuído para a detecção de organismos potencialmente úteis como agentes de controle biológico e na determinação de mapas de áreas preferenciais para o estabelecimento de políticas públicas. No futuro, os grupos prioritários de estudo devem incluir os Annelida e os Nematoda, pelo potencial que ambos têm como organismos benéficos, ou pelo potencial que alguns Nematoda têm como organismos prejudiciais a plantas e animais.

Abstract The variability of the organisms living in a given area constitute what is referred to as biodiversity, one of nature’s fundamental properties, responsible for the balance and stability of ecosystems. The loss of biodiversity has been of great concern to scientists, especially because of the role played by human activities in this regard, able to lead to irreversible circumstances. The São Paulo Research Foundation (Fundação de Amparo à Pesquisa do Estado de São Paulo, FAPESP) plays a major role in supporting research efforts in the most diverse branches of science. In the late 1990´s, FAPESP launched a major program to promote research on biodiversity, named BIOTA/FAPESP. So far, this program has financed the conduction of 26 projects, involving research activities in most of Brazil, while focusing mainly the State of São Paulo. These projects have generated about 1140 publications in peer-reviewed journals of high standard, providing relevant information, including the original description of 1187 species and 76 genera, the complementary description of 350 species, as well as a number of inventory works, biological studies, etc. The program has also been instrumental in the establishment or adequacy of research facilities and training of new taxonomists. Most extensively studied groups of terrestrial invertebrates include Insecta of the orders Hymenoptera, Lepidoptera and Diptera, and Arachnida of the subclasses Araneae and Acari. Distinct projects have also contributed to the detection of organisms potentially useful as biological control agents and in the determination of maps of major interest for the establishment of public policies. In the future, priority groups for study should include the Annelida and the Nematoda, for the potential both have as beneficial organisms, or for the potential some Nematoda have as organisms harmful to plants and animals.

Abstract The software-defined radio has been allowing engineers the possibility of implementing operations on software that were previously only possible to be performed through hardware. With the continuous increase in the processing capacity of computers, it is possible to modify in real time the operating parameters of new radios called Software Defined Radios (SDR) or use commercial devices for other purposes, in addition to those established in their design. By using a low-cost device RTL-SDR R820T2, controlled by a Raspberry Pi 3, with a free software, the present work proposes a characterization procedure in order to collect power levels measurements in a given frequency range with greater accuracy, acting as a spectrum analyzer. Preliminary measures were performed with the device embarked on a drone.

Resumo A expansão da agricultura na área de transição Amazônia-Savana diminuiu muito a cobertura florestal, influenciando a estrutura e o funcionamento dos sistemas de riachos. Avaliamos o efeito da perda de cobertura florestal na integridade dos riachos avaliando as condições físicas do ambiente e a diversidade taxonômica e funcional das assembleias de peixes nesta área de transição. Nossa hipótese é que a baixa cobertura florestal, especialmente adjacente ao riacho, resulta em más condições físicas (por exemplo, temperaturas mais quentes, e menos estrutura física) o que por sua vez diminuirá os valores da diversidade taxonômica e funcional das assembleias de peixes. Detectamos que a perda de cobertura florestal afeta negativamente as condições naturais e reduz a diversidade funcional das assembleias de peixes, mas não encontramos um efeito para a diversidade taxonômica. Predadores de emboscada e espreita, catadores de superfície diurnos, pastores, catadores e navegadores foram os grupos funcionais que tiveram a relação mais forte com ambientes alterados. Esses grupos podem explorar diferentes nichos, tanto com características naturais quanto alterados pela ação antrópica. Nossos resultados sugerem a preservação da zona ripária a fim de evitar a perda de espécies especializadas das assembleias de peixes de riachos.

Abstract The expansion of agriculture in the southeast Amazon-Savanah transitional area has greatly decreased forest cover and influenced stream structure and functioning. We assessed the effects of forest cover loss on the integrity of streams by assessing stream physical conditions and the taxonomic and functional diversity of fish assemblages in this transitional area. We hypothesize that low forest cover, especially adjacent to streams, results in poor physical conditions (e.g., warmer temperatures, less physical structure, etc.), which in turn will decrease the taxonomic and functional diversity of fish assemblages. We detected that loss of forest cover negatively affects natural stream conditions and reduces the functional diversity of fish assemblages, but we did not find a strong effect on taxonomic diversity. Ambush and stalking predators, diurnal surface pickers (groups that exhibit opportunistic life history strategies), grazers, pickers, and browsers (groups that exhibit equilibrium life history strategies) were the functional groups with the strongest relation to altered environments. These groups can explore different niches, both with natural characteristics or altered by human activities. Our results suggest that the preservation of riparian zones can minimize the loss of specialized fish species in assemblages of Amazon-Savannah stream systems.

Abstract The use of native species’ stem cuttings in riparian forests disturbed by silting could be a promising low-tech alternative for restoration practitioners in riverscape rehabilitation. In this study, we evaluated the vegetative propagation of Amazonian native plants (Buchenavia parviflora, Euterpe oleracea, Ficus insipida and Socratea exorrhiza) with the addition of a bio-fertilizer, and humic and fulvic acids in soil disturbed by human-induced silting. We found that F. insipida and B. parviflora were able to grow and showed high survival percentage with the development of leaves, buds, and roots; even in nutrient deficient and clayey soils. We also found that the frequency of application and the concentration of the organic additives did not show significant influence on plants’ development. Thus, advance in situ tests with both species could be an interesting step to contribute to riverine ecosystems restoration practices.

RESUMEN Determinamos la composición química y exploramos la hipótesis de que el aceite esencial de los frutos de Pimenta dioica inhibe el desarrollo micelial de los hongos Fusarium oxysporum f. sp. lycopersici, F. oxysporum f. sp. passiflorae, F. subglutinans f. sp. ananas, F. oxysporum f. sp. vasinfectum e F. oxysporum f. sp. Cubense. Para hacer esto, extrajimos el aceite por hidrodestilación, identificamos sus componentes por cromatografía de gases acoplada a espectrometría de masas (GC-EM) y determinamos la actividad fúngica contra cinco formas especiales de especies de Fusarium. Los resultados mostraron que el aceite tenía 76,88% de eugenol e inhibió el desarrollo micelial de hongos hasta 97,78% en un promedio de 7,2 días. Por lo tanto, el aceite es un potencial fungicida natural.

SUMMARY We determined the chemical composition and explored the hypothesis that the essential oil of the fruits of Pimenta dioica inhibits the mycelial development of fungi Fusarium oxysporum f. sp. lycopersici, F. oxysporum f. sp. passiflorae, F. subglutinans f. sp. ananas, F. oxysporum f. sp. vasinfectum e F. oxysporum f. sp. Cubense. To do this, we extracted the oil by hydrodistillation, identified its components by gas chromatography coupled to mass spectrometry (GC-MS) and determined the fungal activity against five special forms of Fusarium species. The results showed that the oil had 76.88% of eugenol and inhibited the mycelial development of fungi up to 97.78% in an average of 7.2 days. Therefore, oil is a potential natural fungicide.

Objective: Parkinson’s disease (PD) is often accompanied by stigma, which could contribute to a worse prognosis. The objective of this study is to identify the variables associated with stigma in PD patients who are candidates for deep brain stimulation (DBS). Methods: We investigated sociodemographic and clinical variables associated with stigma in a sample of 54 PD patients indicated for DBS. The independent variables were motor symptoms assessed by the Movement Disorder Society‐sponsored revision of the Unified Parkinson Disease Rating Scale (MDS-UPDRS III), depressive symptoms measured by the Hospital Anxiety and Depression Scale, age, disease duration and the presence of a general medical condition. The Mobility, Activities of daily living and Emotional well-being domains of the 39-item Parkinson’s Disease Questionnaire (PDQ-39) were also investigated as independent variables, and the Stigma domain of the PDQ-39 scale was considered the outcome variable. Results: After multiple linear regression analysis, activities of daily living remained associated with the Stigma domain (B = 0.42 [95%CI 0.003-0.83], p = 0.048). The full model accounted for 15% of the variance in the Stigma domain (p = 0.03). Conclusions: Although causal assumptions are not appropriate for cross-sectional studies, the results suggest that ADL difficulties could contribute to greater stigma in PD patients with refractory motor symptoms who are candidates for DBS.

RESUMO O Sistema de Drenagens do Norte do Pará abrange os afluentes da margem esquerda do Rio Amazonas, na região sul do Escudo das Guianas no estado do Pará, Brasil. Cinco das áreas estaduais protegidas da região são consideradas estratégicas para a conservação da biodiversidade. No presente estudo, nós acessamos a ictiofauna das cinco áreas de proteção estadual do Sistema de Drenagens do Norte do Pará. Sete expedições foram realizadas entre os meses de janeiro de 2008 e janeiro de 2009, amostrando trechos das bacias dos rios Cuminá, Cuminapanema, Curuá, Jari, Mapuera, Nhamundá e Paru. As expedições resultaram em 286 espécies pertencentes a 38 famílias e oito ordens, incluindo sete novos registros de peixes para o Brasil, seis deles também representando novos registros para a bacia Amazônica. Nossos resultados fornecem uma base sólida para futuros programas de pesquisa e conservação nas áreas de proteção da região.

ABSTRACT The Northern Pará Drainage System encompasses the left-bank tributaries of the Amazonas River in the southern Guiana Shield region of Pará state, Brazil. Five of the region’s state protected areas are considered strategic for the conservation of its biodiversity. In the present study, we assessed the ichthyofauna of the five state protected areas of the Northern Pará Drainage System. Seven expeditions were conducted between January 2008 and January 2009, which surveyed stretches of the Cuminá, Cuminapanema, Curuá, Jari, Mapuera, Nhamundá, and Paru rivers. These surveys yielded 286 species belonging to 38 families and eight orders, including seven new records of fish species for Brazil, six of which are also new records for the Amazon basin. Our results provide a valuable database for future research and conservation programs in the protected areas of the region.

RESUMO Objetivou-se com esta pesquisa, determinar o coeficiente duplo de cultivo de uma cultivar de soja de ciclo precoce para o município de Tangará da Serra, MT, utilizando lisímetros de pesagem de alta precisão. O método utilizado foi o do coeficiente de cultivo dual (Kc dual) do Boletim 56 da FAO, constituido pelo coeficiente de evaporação do solo (Ke), determinado por microlisímetros e pelo coeficiente basal da cultura (Kcb), determinado por lisímetros de pesagem. Para o cálculo da evapotranspiração de referência (ETo) utilizou a equação de Penman-Monteith. A semeadura e a colheita da soja foram realizadas na safra 2015/16 com espaçamento entre fileiras de 0,45 m. A evapotranspiração de referência (ETo) estimada para o período de cultivo foi de 267,06 mm; a evapotranspiração da cultura foi de 323,61 mm durante todo seu ciclo. O valor de Kcb determinado por lisímetros para o cultivo da soja foi de 0,47, 1,15 e 0,89 para a fase inicial, intermediária e final, respectivamente; para o Ke, nas fases inicial, intermediária e final foi de 0,94, 0,14 e 0,44, respectivamente.

ABSTRACT The objective of this study was to determine the dual crop coefficient of an early-cycle soybean cultivar for the city of Tangará da Serra, MT, Brazil, using high-precision lysimeters. The method used was the dual crop coefficient (dual Kc) of FAO Bulletin 56, constitued by soil evaporation coefficient (Ke), determined by microlysimeters, and by basal crop coefficient (Kcb), determined by weighing lysimeters. Reference evapotranspiration (ETo) was calculated using the Penman-Monteith equation. Soybean sowing and harvesting were performed in the 2015/16 season with spacing of 0.45 m between rows. The reference evapotranspiration (ETo) estimated for the cultivation period was 267.06 mm; the crop evapotranspiration was 323.61 mm throughout its cycle. The Kcb values determined by lysimeters for soybean cultivation were 0.47, 1.15 and 0.89 for the initial, intermediate and final stages, respectively; Ke values at the initial, intermediate and final stages were 0.94, 0.14 and 0.44, respectively.

Resumo O presente artigo traz uma revisão da principal literatura produzida pelo Grupo de Estudos Arqueométricos do Instituto de Pesquisas Energéticas e Nucleares, Comissão Nacional de Energia Nuclear, de São Paulo (IPEN-CNEN/SP), criado em 1997, como consequência de uma iniciativa internacional para motivar o uso de técnicas nucleares para caracterização de materiais arqueológicos. Desde aquele momento, e até hoje, o grupo tem desenvolvido parcerias com pesquisadores/as de diferentes regiões do Brasil e de outros países para oferecer subsídios à compreensão interdisciplinar das cadeias operatórias de produção da cerâmica. Além disso, também vem aportando dados para o estudo multielementar e mineralógico de depósitos arqueológicos. Ao descrever brevemente os princípios das técnicas empregadas e a síntese dos resultados obtidos para cada estudo de caso, o objetivo foi demonstrar a contribuição das análises físico-químicas para questões relacionadas a aspectos culturais, como escolhas tecnológicas compartilhadas, redes de trocas e interações sociais em diferentes períodos do passado.

Abstract The present paper brings together key literature produced by the Group of Archaeometric Studies of the Nuclear and Energy Research Institute, IPEN – National Nuclear Energy Commission (São Paulo, Brazil). This group was founded in 1997, as a result of an international initiative to encourage the use of nuclear techniques for the characterization of archaeological materials. Since then, the Group has developed interdisciplinary partnerships with researchers from Brazil and other countries to offer analytical tools for unraveling ceramic chaîne opératoires in different contexts. Such studies have contributed towards wider cultural interpretations regarding shared technological choices and artifact exchange networks in different social groups. Recently, the Group has also used multi-elemental and mineralogical techniques to tackle questions over the formation of archaeological deposits. This paper briefly explains the analytical principles of the employed techniques, and emphasizes how the results of each case study contribute to the interpretation of specific archaeological problems.
