Abstract Capillaria Zeder, 1800, parasitizes the organs and tissues of several hosts, including the domestic duck Cairina moschata (Linnaeus). This article describes a new species of Capillaria in domestic ducks identified based on morphological studies and molecular analyses of the ribosomal RNA gene. Thirty-eight specimens of C. moschata from the municipality of Soure, Marajó Island, Pará, Brazil. The organs of the birds' digestive tract were analyzed under a stereomicroscope to confirm the parasitic infection, after which the collected nematodes were identified by light microscopy, scanning electron microscopy, and molecular analysis. Capillariids parasitized the intestine and cecum of the examined birds. These parasites had three bacillary bands and a pair of elongated precloacal papillae on the tail. Phylogenetic analysis indicated that the new species formed a sister clade with Capillaria spinulosa (Linstow, 1890), as described in Indonesia and Japan. Based on morphological distinctions and molecular data, Capillaria cairina n. sp. can be considered a new parasite species of C. moschata in the Brazilian Amazon.

Resumo Capillaria Zeder, 1800 parasitam órgãos e tecidos de diversos hospedeiros, incluindo o pato doméstico Cairina moschata (Linnaeus). Este artigo descreve uma nova espécie de Capillaria em patos domésticos, identificada com base em estudos morfológicos e análises moleculares do gene do RNA ribossomal. Trinta e oito espécimes de C. moschata oriundo dos no município de Soure, Ilha de Marajó, Pará, Brasil. Os órgãos do aparelho digestivo das aves foram analisados em estereomicroscópio para confirmar a infecção parasitária. Após, os nematódeos coletados foram identificados por microscopia de luz, microscopia eletrônica de varredura e análises moleculares. Os capilarídeos parasitaram intestino e ceco das aves examinadas. Esses parasitas apresentaram três bandas bacilares e um par de papilas pré-cloacais alongadas na cauda. A análise filogenética indicou que a nova espécie formou um clado irmão com Capillaria spinulosa (Linstow, 1890), conforme descrito na Indonésia e no Japão. Com base na distinção morfológica e dados moleculares, Capillaria cairina n. sp. pode ser considerada uma nova espécie de parasita de C. moschata na Amazonia brasileira.

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 quantificar os teores de C nos reservatórios da biomassa vegetal de diferentes espécies da Caatinga, floresta tropical seca do Nordeste do Brasil. Foi realizado um estudo florístico e fitossociológico prévio e selecionadas nove espécies de maior densidade absoluta, que representou 87% do fragmento. Foram amostradas biomassa dos compartimentos folhas e lenho de cada uma das espécies para determinação do teor de C. Como resultado, houve diferença nos teores foliares de C entre as espécies. O teor de C foliar das espécies variou entre 448,0 e 454,3 g C por kg de biomassa seca e o teor de C do lenho das espécies variou entre 451,4 e 453,1 g C por kg de biomassa seca. Esses resultados sugerem a utilização de fator de conversão de biomassa para carbono específico por espécie em Caatinga, como alternativa ao fator genérico de 50% recomendado pelo IPCC. Esta pesquisa revela que o uso do fator recomendado pelo IPCC superestima estoques de C em Caatinga. Mais estudos são encorajados para confirmar esse resultado.

ABSTRACT This study aimed to quantify the carbon contents in biomass reservoirs of different species in a Tropical Dry Forest located in Northeast, Brazil. We developed a previous floristic and phytosociological study and selected the nine highest absolute density (AD) species of the fragment, representing 87% of the fragment AD. We sampled the leaves and stem tissues of each species for carbon content determination. As result, the leaf C content differed between the species. The C leaf content ranged between 448.0 and 454.3 g C per kg of dry biomass. The C stem content varied between the species from 451.4 to 453.1 g C per kg of dry biomass. Our results suggest the use of a species-specific biomass-carbon conversion factor in Caatinga, as an alternative to the 50% factor recommended by the IPCC. This research reveals that the use of the factor recommended by the IPCC overestimates C stocks in Caatinga. Further studies are encouraged to confirm this result.

Resumo O baiacu amazônico Colomesus psittacus é um peixe de importância comercial para a aquariofilia, além de ser capturado como bycacth e descartado morto no ambiente nas pescarias artesanais que ocorrem nos estuários da região Norte do Brasil. Nesse sentido, objetivou-se identificar e descrever nematódeos do gênero Huffmanela em baiacus oriundos da ilha de Marajó, bem como as alterações histopatológicas causadas por eles. Cinquenta e cinco peixes foram analisados, e trinta e cinco espécimes apresentaram o parasita nas branquias. Características morfológicas sugerem tratar-se de uma nova espécie do gênero Huffmanela, e os exames histopatológicos demonstraram uma inflamação edematosa na lamela secundária e presença de ovos desse nematódeo. Esse fato se torna o primeiro registro desse gênero parasito em C. psittacus no Brasil.

Abstract The puffer fish Colomesus psittacus, is not commercialized on Marajó Island. They are captured as bycacth and discarded dead in the environment in artisanal fisheries that occur in the estuaries of northern Brazil. In this sense, the objective was to identify the parasites present in the gills and to evaluate the histopathological alterations caused by these nematodes of the genus Huffmanela. Fifty-five fish were analyzed, and thirty-five specimens showed the parasite in the gills. Morphological characteristics suggest that it is a new species of the genus Huffmanela, and the histopathological exams showed an edematous inflammation in the secondary lamella and the presence of eggs of this nematode, which is the first record of this parasite in C. psittacus in Brazil.

An infection of the fungus Moniliophthora perniciosa in cocoa trees reduces productivity of the plant. In this study, the concentrations of mineral nutrients in healthy leaves and in leaves of vegetative broom of the cocoa plant were determined, and the relationship between the disease and the nutritional composition of the leaves was assessed. The samples were analyzed using the wet digestion method and the concentrations were determined by inductively coupled plasma optical emission spectrometry and the Kjeldahl method. Results indicate that leaves of vegetative broom have lower concentrations of Ca, Mg, S, Fe, Mn, and Ni than healthy leaves. Concentrations of P and Cu were lower in healthy leaves and higher in leaves of vegetative broom. In contrast, concentrations of K, N, and Zn were the same for both types of leaves. In short, plant-fungal interaction was reflected in the nutritional composition of the leaves, demonstrated by the differences in nutrient concentrations between healthy and infected leaf tissue.

RESUMEN Ofiofagia es un hábito alimenticio común en serpientes, sin embargo, hay pocos registros de este comportamiento para el género Bothrops. En el presente trabajo reportamos el primer caso de depredación de Bothrops moojeni en Amerotyphlops brongersmianus. Nuestro registro refuerza el conocimiento del hábito generalista de Bothrops moojeni e indica una dieta oportunista de esta especie.

ABSTRACT Ophyophagy is a common feeding habit in snakes; however, there are few records of this behavior for the genus Bothrops. Here, we report the first case of predation of Bothrops moojeni upon Amerotyphlops brongersmianus. Our record reinforces the known generalist habit of Bothrops moojeni and indicates an opportunistic diet.

RESUMO O cementoblastoma é um tumor odontogênico mesenquimal benigno, de crescimento lento e ilimitado. Devido à sua raridade, relatamos o caso de uma mulher de 24 anos, que apresentou queixas álgicas e aumento de volume na região mandibular esquerda. Os exames de imagem identificaram lesão hiperdensa com halo hipodenso, associada às raízes dos elementos 35, 36 e 37. O exame histopatológico foi importante para o diagnóstico de cementoblastoma. O tratamento proposto consistiu na enucleação da massa tumoral junto à exodontia dos dentes envolvidos e à osteotomia do remanescente ósseo. A paciente encontra-se em acompanhamento há um ano, sem sinais de recidiva.

ABSTRACT Cementoblastoma is a benign, slow-growing, and unlimited mesenchymal dental tumor. Due to its rarity, we aimed to report the case of a 24-year-old female patient who presented pain complaints and increased volume in the left mandibular region. Imaging tests showed a hyperdense lesion with hypodense halo, associated with the roots of elements 35, 36, and 37. Histopathology revealed diagnosis of cementoblastoma. The proposed treatment consisted of the enucleation of the tumor mass together with the exodontia of the teeth involved and osteotomy of the bone remnant. The patient has been under follow-up for one year with no signs of recurrence.

Abstract We present postmortem evidence of invasive pulmonary aspergillosis (IPA) in a patient with severe COVID-19. Autopsies of COVID-19 confirmed cases were performed. The patient died despite antimicrobials, mechanical ventilation, and vasopressor support. Histopathology and peripheral blood galactomannan antigen testing confirmed IPA. Aspergillus penicillioides infection was confirmed by nucleotide sequencing and BLAST analysis. Further reports are needed to assess the occurrence and frequency of IPA in SARS-CoV-2 infections, and how they interact clinically.

Resumo Este estudo investigou a sensibilidade de modelos acoplados oceano-atmosfera do CMIP3 e do CMIP5 para o período de 1979-1999 em simular a magnitude do gradiente meridional de anomalias de Temperaturas da Superfície do Mar (TSM) no Atlântico Tropical. Nos resultados são apresentadas análises comparativas para este gradiente meridional de anomalias de TSM de dois períodos sazonais (verão e outono austrais). Os resultados mostraram a evolução dos modelos em simular as variações das anomalias de TSM desse gradiente do CMIP3 para o CMIP5. Para o CMIP3 os modelos não tiveram um bom desempenho em ambas as estações. Para o CMIP5 o verão apresentou o maior número de modelos com índice de desempenho de Willmott (igual ou acima de mediano ID ≥ 0,6).

Abstract This study investigated the sensitivity models coupled ocean-atmosphere of CMIP3 and CMIP5 for the period of 1979-1999 to simulate the magnitude of the meridional gradient of sea surface temperature anomalies (SST) in Atlantic Tropical. In the results are presented to comparative analyses for this meridional gradient of SST anomalies of two seasonal seasons (summer and autumn autrais). The results showed the evolution of the models in simulating the variations of SST anomalies of this gradient from CMIP3 to CMIP5. For CMIP3 the models did not good perform in both seasons. For the CMIP5 the summer presented the highest number of models with Willmott performance index (equal to or above the median ID ≥ 0.6).

ABSTRACT Objective To verify the presence of variants in HNF1B in a sample of the Brazilian population selected according to the presence of renal cysts associated with hyperglycemia. Subjects and methods We evaluated 28 unrelated patients with clinical suspicion of HNF1B mutation because of the concomitant presence of diabetes mellitus (DM) or prediabetes and renal cysts. Genotyping was accomplished using Sanger sequencing or multiplex ligation-dependent probe amplification (MLPA). In positive cases, available relatives were recruited. Results We found two patients with HNF1B mutations. The first presented the variant p.Pro328Leufs*48(c.983delC) and had DM, renal cysts, and hypomagnesemia. The second presented a heterozygous whole gene deletion in HNF1B, DM, renal cysts, body and tail pancreatic agenesis, and hypomagnesemia; this alteration was also found in his two siblings and his father. Conclusion The recruitment of suspected cases of HNF1B gene mutations in Brazilians due to hyperglycemia and renal cysts presents two positive cases. Our cases contribute to the annotation of clinical and biochemical phenotypes of this rare form of maturity-onset diabetes of the young (MODY).

Abstract. Cercospora agavicola, causal agent of the gray spot of blue agave (Agave tequilana), is a regulated fungus under official control in states under the Denomination of Origin of Tequila (DOT). This work was carried out in Jalisco, Mexico, the main DOT region, to determine the spatial-temporal epidemic inductivity of the fungus and to develop stochastic models to forecast the gray spot in order to support regional preventive programs. Monthly, from October 2016 to December 2017 the severity, incidence and number of diseased plants were evaluated in 41 plots established in commercial agave plantations of 3-4 years of age selected with weighted risk criteria in Los Altos (20), Valleys (11) and South (10). The regional epidemic inductivity of C. agavicola was heterogeneous with a greater risk for at least nine counties of Los Altos. However, low epidemic rates (0.0008-0.006 units week-1), strong restriction spread (1-4 plants), reduced annual increment of incidence (0-32 plants / 0.5 ha) and no spore capture evidenced the low parasitic fitness and reduced fungus epidemic potential. Consequently, limited predictive capacity was found even with the best goodness of fit models (R2 adj 0.51-0.60). The favorable hours (HFav) of January-April, with respect to infection, was consistent among models, so it can be used as preventive algorithm in SIVEA (www.sivea.org.mx). The regional losses were estimated between 237 thousand US dollars and 98.01 MDD. Cercosporin, a toxin associated with Cercospora genus, may be involved in atypical linear temporal progress and should be integrated in future research.

Resumen. Cercospora agavicola, agente causal de la mancha gris del agave azul (Agave tequilana), es un hongo reglamentado bajo control oficial en estados bajo Denominación de Origen del Tequila (DOT). Este trabajo se desarrolló en Jalisco, México, principal región DOT, para determinar la inductividad epidémica espacio-temporal del hongo y desarrollar modelos estocásticos de pronóstico de la mancha gris con el fin de sustentar acciones preventivas regionales. De octubre 2016 a diciembre 2017 se evaluó mensualmente la severidad, incidencia y número de plantas enfermas en 41 parcelas establecidas en plantaciones comerciales de agave de 3-4 años de edad seleccionadas con criterios ponderados de riesgo en Los Altos (20), Valles (11) y Sur (10). La inductividad epidémica regional de C. agavicola fue heterogénea con mayor riesgo para al menos nueve municipios de Los Altos. Sin embargo, bajas tasas epidémicas (0.0008-0.006 unidades semana-1), fuerte restricción de contagio (1-4 plantas), reducido incremento anual de incidencia (0-32 plantas/0.5 ha) y nula captura de esporas evidenciaron la baja aptitud parasítica y epidémica del hongo. Consecuentemente, se encontró limitada capacidad predictiva aun con los mejores modelos generados (R2 adj 0.51-0.60). Las horas favorables (HFav) de enero-abril, respecto a la infección, fue consistente entre modelos por lo que puede integrarse como algoritmo preventivo en SIVEA (www.sivea.org.mx). Las pérdidas regionales establecidas se estimaron entre 237 mil dólares americanos y 98.01 MDD. La cercosporina, toxina asociada al género Cercospora, puede estar implicada en el progreso temporal lineal atípico y debe integrarse en futuras investigaciones.

ABSTRACT Diabetes mellitus is a syndrome that reaches more than 382 million people worldwide. It interferes with the metabolism of carbohydrates, causing chronic hyperglycemia. The objective of this study was to evaluate the effect of the Copaifera duckei, Dwyer, Fabaceae, oleoresin on streptozotocin-induced (STZ) diabetic rats. This study was based on the induction of diabetes mellitus by streptozotocin (55 mg/kg, i.p.) in Wistar rats and treated with doses of C. duckei oleoresin (250 and 500 mg/kg, p.o.). Subsequently, the clinical, biochemical and histopathological of the pancreas parameters were evaluated. Gas chromatographic analysis indicated that β-bisabolene (22.29%), β-caryophyllene (21.25%) and α-farnesene (15.58%) sesquiterpenes were the major components of the C. duckei oleoresin. In streptozotocin-induced diabetes mellitus, it was possible to observe that the C. duckei oleoresin treatment had a significant effect (p < 0.001) on the clinical parameters, and that there was a positive improvement. This was attenuated by the urea, creatinine, and transaminases alterations (p < 0.001) observed in animals with diabetes mellitus, as well as the significantly reduced (p < 0.001) values of total cholesterol, triacylglycerides, and glucose. In the histopathological analyses of the pancreas, it was observed that the C. duckei oleoresin was able to restore β-cells and to significantly increase the quantity and diameter of the Langerhans islets (p < 0.05), when compared to the diabetic group. The treatment with C. duckei oleoresin, employed under the conditions of this study, presented antidiabetic activity and can improve the complications found in this syndrome.

ABSTRACT The profile of volatile organic compounds, the glandular and non-glandular trichomes of Plectranthus ornatus, obtained by in vitro cultivation, was evaluated in plants grown in Murashide and Skoog medium supplemented with benylaminopurine at 4.5, 9.0, and 18.0 µM + naphthaleneacetic acid at 5.37 µM, kinetin at 4.7, 9.3 and 18.5 µM + naphthaleneacetic acid (5.37 µM) or Murashide and Skoog 0 medium (as a control). Scanning Electron Microscopy was performed on samples of the third leaf node of the 90 days old plants obtained from treatment with 4.5 or 9.0 µM benylaminopurine, and 4.7 or 9.3 µM kinetin. Headspace Solid Phase Micro-Extraction of the 30, 60 and 90 days old in vitro plants permitted to determinate by GC/MS the composition comprised of 62 compounds. The data were analyzed using Principal Component Analysis and Hierarchical Clustering Analysis and, the major constituents of these oils after treatment and aging were monoterpenes and sesquiterpenes. Morphoanatomical analysis of trichomes, by Scanning Electron Microscopy, enabled the identification of non-glandular trichomes and four types of glandular trichomes, which comprised capitate and peltate glandular trichomes that were distributed on both sides of the leaf. We observed that the regulators influenced qualitative and quantitative profiles of the volatile organic compounds and the number and distribution of hairs on the leaf surface.
