Pelvimetria radiográfica em tamanduá-mirim (Tamanduá tetradactyla) para fins reprodutivos e clínicos.

CAPESTamandua tetradactyla é um mamífero de médio porte, encontrado em diversos biomas da América do Sul, o qual possui incursões literárias, principalmente correlatas ao manejo e comportamento em geral, no entanto, pouco se sabe sobre questões referentes a clínica médica, cirúrgica e imaginologia. Diante disso, com o intuito de determinar valores pelvimétricos que permitam auxiliar no manejo clínico e reprodutivo de animais criados em cativeiro, avaliou-se imagens radiográficas da pelve, em projeções ventrodorsal e latero lateral direita de 13 cadáveres, sendo cinco machos e oito fêmeas, jovens e adultos; e um espécime vivo macho, com o objetivo de descobrir a viabilidade desta técnica. As mensurações realizadas foram referentes aos diâmetros: biilíaco superior (DBIS), biilíaco inferior (DBII), biilíaco médio (DBIM), diagonal direito (DDD), diagonal esquerdo (DDE), conjugado verdadeiro (DCV), conjugado diagonal (DCD), vertical (DV), sacral (DSA) e sagital (DSG), áreas de entrada (AEP) e saída da pelve (ASP), além da biometria corporal externa, obtendo-se valores semelhantes entre os indivíduos avaliados, os quais foram calculados os respectivos coeficientes de correlação de Pearson para todas as combinações possíveis entre os parâmetros estudados - significativas quando p < 0,05 e altamente significativas quando p < 0,01. A pelvimetria radiográfica além de possibilitar a classificação anatômica destes animais como dolicopélvica, tornar-se ainda um auxílio diagnóstico importante na rotina clínica do Médico Veterinário.Tamandua tetradactyla is a medium-sized mammal found in several South American biomes, which has literary forays, mainly correlated with general management and behavior, however, little is known about issues related to medical practice, surgery and imaging. Therefore, in order to determine pelvimetric values to assist in the clinical and reproductive management of captive-bred animals, radiographic images of the pelvis were evaluated, in ventral-dorsal and right latero-lateral projections of 13 cadavers, five males and eight females, young and adults; and a live male specimen, aiming to discover the viability of this technique. The measurements performed were related as follows: bi-iliac upper (BIUD), bi-iliac lower (BILD), bi-iliac middle (BIMD), right diagonal (RDD), left diagonal (LDD), true conjugate (TCD), diagonal conjugate (DCD), vertical (VD), sacral (SD) and sagittal (SGD) diameters, in addition to the pelvic inlet (PIA) and pelvic outlet (POA) areas, as well as external body biometrics. Similar values were obtained between the evaluated individuals, and the respective Pearson correlation coefficients were calculated for all possible combinations between the studied parameters - significant when p < 0.05 and highly significant when p < 0.01. Radiographic pelvimetry, in addition to allowing the anatomical classification of these animals as dolichopelvic, is still an important diagnostic aid in the clinical routine of the veterinarians

EQUILIBRIUM MOISTURE IN THERMAL RECTIFICATION WOOD OF CUPIÚBA IN THE AMAZON REGION

O tratamento térmico promove menor umidade de equilíbrio em madeiras, trazendo melhorias em suas propriedades físicas e tecnológicas, bem como reduzindo a higroscopicidade e melhorando sua estabilidade dimensional. O objetivo deste estudo foi analisar a curva de ganho de umidade e o teor de equilíbrio higroscópico sofrido entre as amostras de madeira termorretificadas da espécie Goupia glabra Aubl. (cupiúba). Foram testadas temperaturas de 140 °C, 160 °C e 180 °C durante três horas de tempo, em corpos-de-prova de dimensões de 2x3x5cm, estabeleceu-se 15 corpos-de-prova para cada tratamento. Antes da termorretificação as amostras foram submetidas à sala climatizada calibrada em 12% de umidade de equilíbrio higroscópico, após termorretificadas as amostras retornaram à sala com calibração de 18% de equilíbrio higroscópico para fins de ganho de umidade. Observou-se curva de ganho de umidade crescente na condição de 18% de equilíbrio higroscópico após o processo de termorretificação, sendo que as testemunhas absorveram menos umidade dos que as amostras termo tratadas, porém as amostras submetidas a 180°C absorveram menos umidade do que as de 160 e 140°C, por conta da perda de constituintes hidrófilos. Na mesma condição observou-se que a umidade de equilíbrio dos corpos-de-prova foi maior nas testemunhas, seguidas das temperaturas de 140, 160 e 180 °C respectivamente. Contudo o experimento demonstra que o teor de equilíbrio higroscópico e curva de ganho de umidade influenciaram na redução da higroscopicidade do material madeireiro analisado.Palavras-chave: tratamento térmico, higroscopicidade, dessorção, adsorção.The heat treatment promotes low equilibrium moisture content of wood, bringing improvements in its physical and technological properties, as well as reducing the hygroscopicity and improving the dimensional stability. The objective of this study was to analyze the gain curve of moisture and hygroscopic equilibrium content after thermal rectification of samples Goupia glabra Aubl. (cupiúba). Were applied temperatures of 140 °C , 160 °C and 180 °, for time three hours, in body-of-proves dimensions 2x3x5cm, settled 15 body-of-proves for each treatment. Before the thermal rectification the samples were calibrated temperature-controlled room at 12% moisture of hygroscopic equilibrium after thermal rectification samples returned to the room again and calibration with a 18% hygroscopic equilibrium moisture for the purpose of moisture gain. There was growing moisture gain curve provided of 18 % hygroscopic equilibrium moisture after the thermal rectification, the witnesses absorbed less moisture that the samples underwent thermal rectification, but the samples subjected to 180 ° C absorbed less moisture of which 160 and 140 °C, as a consequence of loss of hydrophilic components. In the same condition it was observed that the equilibrium moisture content of the body-of-proves was larger in witnesses, followed by temperatures of 140, 160 and 180 °C respectively. However, the experiment evidence that the equilibrium moisture content and gain curve moisture influenced the reduction of hygroscopicity of wood material analyzed.Keywords: heat treatment; hygroscopicity; desorption; adsorption

DIAGNOSIS OF DIOCTOPHYMA RENALE USING ULTRASONOGRAPHY AND MICROSCOPY - A CASE REPORT

Dioctophyma renale is classified as a cosmopolitan zoonotic helminth, belonging to Nematoda class and Dioctophymoidea superfamily. Dogs are considered definitive hosts, suffering with large kidney damage, and the disease diagnosis can be done through ultrasound, x-ray and light microscopy. The aim in this paper was to report the sonographic and microscopic aspects of a canine affected by Dioctophyma renale. Dark colored urine evolving to hematuria and abdominal pain was the main symptoms observed in the animal. Performing urinalysis it was verified D. renale eggs. Ultrasonography could observe total destruction of the right renal parenchyma, hyperechoic structures of cylindrical and rounded shape bounded by the renal capsule, suggesting the presence of the parasite, while the left kidney had normal size. The animal was submitted to nephrectomy, confirming the worm presence, measuring 31.8 cm long. It can be stated that ultrasound and light microscopy are highly effective to establish a definitive diagnosis of Dioctophyma renale

O objetivo deste trabalho foi avaliar o acúmulo e a liberação de nutrientes (N, P, K, Ca, Mg e S) de resíduos culturais de plantas de cobertura na entressafra, em condições de Cerrado. O experimento foi conduzido em um Latossolo Vermelho distroférrico com textura argilosa. As plantas de cobertura avaliadas foram: amaranto (Amaranthus cruentus L.), milheto (Pennisetum glaucum L.) e capim-pé-de-galinha (Eleusine coracana (L.) Gaertn.). O delineamento experimental utilizado foi o de blocos ao acaso, no esquema de parcelas subdivididas, com quatro repetições. Na fase de florescimento das espécies, foi avaliada a produção de matéria seca e o acúmulo de nutrientes. A fim de avaliar a liberação de nutrientes dos resíduos culturais, o material vegetal de cada espécie foi acondicionado em sacolas de náilon, as quais foram dispostas sobre o solo e seu conteúdo analisado em intervalos de 30 dias, até 240 dias após sua instalação. As maiores quantidades de nutrientes acumulados na fitomassa das plantas de cobertura foram observadas no milheto e no capim-pé-de-galinha. O potássio foi o nutriente acumulado em maior quantidade, chegando a atingir 416,9 kg ha-1 no milheto. As maiores taxas de liberação de nutrientes foram observadas nos resíduos culturais do amaranto.The objective of this work was to evaluate the accumulation and the liberation of nutrients (N, P, K, Ca, Mg and S) of cultural residues by three species of cover crops, in off-season. Tested cover crops were amaranthus (Amaranthus cruentus L.), pearl millet (Pennisetum glaucum L.) and finger millet (Eleusine coracana (L.) Gaertn.). The experiment was carried out in a Typic Haplorthox clay texture soil. A randomized block desing in a split-plot array in time, with four replications, was used. At the flowering of the species, the production of dry matter and the accumulation of nutrients were evaluated. Proportional samples of dry matter of each cover crop species were placed in litter bags, which were distributed on the field plots surface, collected and weighed every 30 days, until 240 days after installation of the bags. The largest amounts of accumulated nutrients in the dry matter of the cover crops were observed with the pearl millet and the finger millet. The potassium was the nutrient accumulated in larger amount, reaching 416.9 kg ha-1, in pearl millet. The largest rates of nutrient liberation were observed in the cultural residues of the amaranthus

Pododermatite associada à piometra em coelho doméstico (Oryctolagus cuniculus): relato de caso

Este trabalho tem como objetivo relatar um caso de pododermatite bacteriana em coelho doméstico com quadro concomitante de piometra. Foi atendido no ambulatório de animais selvagens anexo ao Hospital Veterinário Professor Mário Dias Teixeira da Universidade Federal Rural da Amazônia, um coelho doméstico (Oryctolagus cuniculus) fêmea, adulta, da raça Nova Zelândia, pesando 2,248kg, tendo como queixas principais diarreia, disúria, emagrecimento, secreção vaginal e presença de abscessos nos quatro membros. Após realização de exame ultrassonográfico, foi diagnosticada com piometra, sendo indicada ovariosalpingohisterectomia terapêutica e drenagem dos abscessos podais. Durante o transoperatório, foi coletado material do interior dos abscessos para análise microbiológica e realização de antibiograma, sendo identificada a presença da bactéria Staphylococcus sp. Posteriormente, foi indicado tratamento com antibiótico e anti-inflamatório sistêmicos, ambos por via oral, além de tratamento tópico com pomada antibiótica e cicatrizante, porém, o animal foi a óbito cinco dias após o procedimento. Este relato ilustra que as condições inadequadas de manejo podem resultar em diversas patologias, a exemplo da pododermatite. Além disso, neste caso, o prognóstico era reservado, especialmente pela condição clínica da paciente, agravada pela presença de piometra e, possivelmente, instalação de septicemia

Geographic patterns of tree dispersal modes in Amazonia and their ecological correlates

Aim: To investigate the geographic patterns and ecological correlates in the geographic distribution of the most common tree dispersal modes in Amazonia (endozoochory, synzoochory, anemochory and hydrochory). We examined if the proportional abundance of these dispersal modes could be explained by the availability of dispersal agents (disperser-availability hypothesis) and/or the availability of resources for constructing zoochorous fruits (resource-availability hypothesis). Time period: Tree-inventory plots established between 1934 and 2019. Major taxa studied: Trees with a diameter at breast height (DBH) ≥ 9.55 cm. Location: Amazonia, here defined as the lowland rain forests of the Amazon River basin and the Guiana Shield. Methods: We assigned dispersal modes to a total of 5433 species and morphospecies within 1877 tree-inventory plots across terra-firme, seasonally flooded, and permanently flooded forests. We investigated geographic patterns in the proportional abundance of dispersal modes. We performed an abundance-weighted mean pairwise distance (MPD) test and fit generalized linear models (GLMs) to explain the geographic distribution of dispersal modes. Results: Anemochory was significantly, positively associated with mean annual wind speed, and hydrochory was significantly higher in flooded forests. Dispersal modes did not consistently show significant associations with the availability of resources for constructing zoochorous fruits. A lower dissimilarity in dispersal modes, resulting from a higher dominance of endozoochory, occurred in terra-firme forests (excluding podzols) compared to flooded forests. Main conclusions: The disperser-availability hypothesis was well supported for abiotic dispersal modes (anemochory and hydrochory). The availability of resources for constructing zoochorous fruits seems an unlikely explanation for the distribution of dispersal modes in Amazonia. The association between frugivores and the proportional abundance of zoochory requires further research, as tree recruitment not only depends on dispersal vectors but also on conditions that favour or limit seedling recruitment across forest types

Geography and ecology shape the phylogenetic composition of Amazonian tree communities

AimAmazonia hosts more tree species from numerous evolutionary lineages, both young and ancient, than any other biogeographic region. Previous studies have shown that tree lineages colonized multiple edaphic environments and dispersed widely across Amazonia, leading to a hypothesis, which we test, that lineages should not be strongly associated with either geographic regions or edaphic forest types.LocationAmazonia.TaxonAngiosperms (Magnoliids; Monocots; Eudicots).MethodsData for the abundance of 5082 tree species in 1989 plots were combined with a mega-phylogeny. We applied evolutionary ordination to assess how phylogenetic composition varies across Amazonia. We used variation partitioning and Moran's eigenvector maps (MEM) to test and quantify the separate and joint contributions of spatial and environmental variables to explain the phylogenetic composition of plots. We tested the indicator value of lineages for geographic regions and edaphic forest types and mapped associations onto the phylogeny.ResultsIn the terra firme and várzea forest types, the phylogenetic composition varies by geographic region, but the igapó and white-sand forest types retain a unique evolutionary signature regardless of region. Overall, we find that soil chemistry, climate and topography explain 24% of the variation in phylogenetic composition, with 79% of that variation being spatially structured (R2 = 19% overall for combined spatial/environmental effects). The phylogenetic composition also shows substantial spatial patterns not related to the environmental variables we quantified (R2 = 28%). A greater number of lineages were significant indicators of geographic regions than forest types.Main ConclusionNumerous tree lineages, including some ancient ones (&gt;66 Ma), show strong associations with geographic regions and edaphic forest types of Amazonia. This shows that specialization in specific edaphic environments has played a long-standing role in the evolutionary assembly of Amazonian forests. Furthermore, many lineages, even those that have dispersed across Amazonia, dominate within a specific region, likely because of phylogenetically conserved niches for environmental conditions that are prevalent within regions

Overall, we find that soil chemistry, climate and topography explain 24% of the variation in phylogenetic composition, with 79% of that variation being spatially structured (R$^{2}$ = 19% overall for combined spatial/environmental effects). The phylogenetic composition also shows substantial spatial patterns not related to the environmental variables we quantified (R$^{2}$ = 28%). A greater number of lineages were significant indicators of geographic regions than forest types.
