RESUMO A brucelose é uma importante zoonose de proporções mundiais. Os testes sorológicos utilizados no Brasil, antígeno acidificado tamponado (RBT), soroaglutinação lenta/2-mercaptoetanol (2-ME), polarização fluorescente (FPA) e fixação de complemento (FC), são baseados no antígeno lipopolissacarídeo liso (S-LPS) da Brucella abortus. O objetivo deste estudo foi avaliar uma proteína BP26 recombinante utilizada como antígeno em um teste rápido imunocromatográfico de fluxo lateral (rBP26-LFIA) para o diagnóstico sorológico da brucelose bovina. As características de desempenho analítico foram avaliadas em amostras de soro bovino positivas e negativas previamente caracterizadas pelos testes RBT e 2-ME. As estimativas da sensibilidade e especificidade analíticas foram de 73,91% e 97,14%, respectivamente. Soros bovinos reagentes à Neospora, Trypanossoma vivax e Leptospira foram utilizados para avaliação de especificidade, em razão de essas doenças serem causas frequentes de aborto em bovinos, além de ser possível reação cruzada induzida por vacinas comerciais contra Leptospira, em testes sorológicos para a brucelose bovina que utilizam S-LPS como antígeno. Como conclusão, o teste rBP26-LFIA, com sua atual padronização, apresentou um bom desempenho analítico. Contudo, uma futura avaliação do desempenho diagnóstico do teste rBP26-LFIA com amostras provenientes de regiões com prevalência conhecidas é necessária para sua recomendação de uso no programa brasileiro de controle e erradicação da brucelose bovina. mundiais Brasil RBT, , (RBT) lenta/2mercaptoetanol lenta2mercaptoetanol lentamercaptoetanol lenta/2 mercaptoetanol lenta 2 2ME, 2ME ME (2-ME) FPA (FPA FC, FC (FC) SLPS S LPS (S-LPS abortus BP BP2 rBP26LFIA rBPLFIA rBP26 LFIA rBP (rBP26-LFIA 2ME.

ABSTRACT Brucellosis is an important bacterial disease of global distribution with zoonotic potencial. Serological tests used in Brazil for diagnosis of bovine brucellosis, including the Rose Bengal test (RBT), 2-mercaptoethanol (2-ME), fluorescent polarization (FPA), and complement fixation (FC), are based on the smooth lipopolysaccharide antigen (S-LPS) of Brucella abortus. The aim of this study was to evaluate a recombinant BP26 protein used as antigen in a rapid lateral flow immunochromatographic assay (rBP26-LFIA) for serological diagnosis of bovine brucellosis. Analytical performance of rBP26-LFIA was evaluated in positive and negative bovine serum samples previously characterized by RBT and 2-ME. Estimates of analytical sensitivity and specificity were 73.91% and 97.14%, respectively. Bovine sera reactive to Neospora, Trypanosoma vivax or Leptospira were used to assess specificity because these diseases are commonly associated with abortion in cattle. In addition to a possible cross-reaction induced by commercial vaccines against Leptospira in serological tests for bovine brucellosis using S-LPS as an antigen. In conclusion, rBP26-LFIA, with its current standardization, had good analytical performance. However, a future evaluation of diagnostic performance by rBP26-LFIA with samples from regions with known prevalence is necessary for its recommendation for use in the Brazilian program for the control and eradication of bovine brucellosis. potencial RBT, , (RBT) 2mercaptoethanol mercaptoethanol 2 2ME, 2ME ME (2-ME) FPA, FPA (FPA) FC, FC (FC) SLPS S LPS (S-LPS abortus BP BP2 rBP26LFIA rBPLFIA rBP26 LFIA rBP (rBP26-LFIA 2ME.

ABSTRACT The limited temporal completeness and taxonomic accuracy of species lists, made available in a traditional manner in scientific publications, has always represented a problem. These lists are invariably limited to a few taxonomic groups and do not represent up-to-date knowledge of all species and classifications. In this context, the Brazilian megadiverse fauna is no exception, and the Catálogo Taxonômico da Fauna do Brasil (CTFB) (http://fauna.jbrj.gov.br/), made public in 2015, represents a database on biodiversity anchored on a list of valid and expertly recognized scientific names of animals in Brazil. The CTFB is updated in near real time by a team of more than 800 specialists. By January 1, 2024, the CTFB compiled 133,691 nominal species, with 125,138 that were considered valid. Most of the valid species were arthropods (82.3%, with more than 102,000 species) and chordates (7.69%, with over 11,000 species). These taxa were followed by a cluster composed of Mollusca (3,567 species), Platyhelminthes (2,292 species), Annelida (1,833 species), and Nematoda (1,447 species). All remaining groups had less than 1,000 species reported in Brazil, with Cnidaria (831 species), Porifera (628 species), Rotifera (606 species), and Bryozoa (520 species) representing those with more than 500 species. Analysis of the CTFB database can facilitate and direct efforts towards the discovery of new species in Brazil, but it is also fundamental in providing the best available list of valid nominal species to users, including those in science, health, conservation efforts, and any initiative involving animals. The importance of the CTFB is evidenced by the elevated number of citations in the scientific literature in diverse areas of biology, law, anthropology, education, forensic science, and veterinary science, among others. publications problem uptodate up date classifications context exception (CTFB http//fauna.jbrj.gov.br/, httpfaunajbrjgovbr http //fauna.jbrj.gov.br/ , jbrj gov br (http://fauna.jbrj.gov.br/) 2015 Brazil 80 specialists 1 2024 133691 133 691 133,69 125138 125 138 125,13 82.3%, 823 82 3 (82.3% 102000 102 000 102,00 7.69%, 769 7 69 (7.69% 11000 11 11,00 . 3,567 3567 567 (3,56 2,292 2292 2 292 (2,29 1,833 1833 833 (1,83 1,447 1447 447 (1,44 1000 1,00 831 (83 628 (62 606 (60 520 (52 50 users science health biology law anthropology education others http//fauna.jbrj.gov.br/ faunajbrjgovbr //fauna.jbrj.gov.br (http://fauna.jbrj.gov.br/ 201 8 202 13369 13 133,6 12513 12 125,1 82.3% (82.3 10200 10 00 102,0 7.69% 76 6 (7.69 1100 11,0 3,56 356 56 (3,5 2,29 229 29 (2,2 1,83 183 83 (1,8 1,44 144 44 (1,4 100 1,0 (8 62 (6 60 52 (5 5 http//fauna.jbrj.gov.br (http://fauna.jbrj.gov.br 20 1336 133, 1251 125, 82.3 (82. 1020 0 102, 7.69 (7.6 110 11, 3,5 35 (3, 2,2 22 (2, 1,8 18 (1, 1,4 14 4 ( 82.

ABSTRACT The expression ‘you need to know to conserve’ is a well-known cliche among biologists. Documenting the richness of a group of organisms is the first step towards understanding biodiversity and preparing efficient conservation plans. In this context, many efforts have been made to quantify the number of species on Earth and estimate the number of species still unknown to science. A few countries have complete and integrated databases estimating the approximate number of species recorded for their territory, particularly in the Global South. In Brazil, a country of continental dimensions, revealing the richness of the second most diverse clade of invertebrates (=Mollusca) has been a goal of taxonomists. Recently, in an unprecedented, collective, and integrated effort among Brazilian malacologists, it was possible to estimate how many valid species of molluscs are there in Brazil. In this effort, more than 30 mollusc experts joined together to update the Taxonomic Catalogue of the Brazilian Fauna (TCBF), a governmental website that allows a quick and real-time updating of all Metazoan. So far, more than 5,000 updates have been made in TCBF, indicating the presence of 3,552 valid species of molluscs in Brazil, distributed among the main clades as follows: Caudofoveata (10 spp.), Solenogastres (6 spp.), Polyplacophora (35 spp.), Scaphopoda (43 spp.), Cephalopoda (92 spp.), Bivalvia (629 spp.) and Gastropoda (2,737 spp.). The present study, in addition to demonstrating for the first time the richness of Brazilian molluscs, also presents the state of the art of this important phylum of invertebrates highlighting its most representative and neglected groups. you conserve wellknown well known biologists plans context science territory South Brazil dimensions =Mollusca Mollusca (=Mollusca taxonomists Recently unprecedented collective malacologists 3 TCBF , (TCBF) realtime real Metazoan far 5000 5 000 5,00 3552 552 3,55 follows 10 (1 spp., spp spp. 6 ( 35 (3 43 (4 92 (9 629 (62 2,737 2737 2 737 (2,73 spp.. . study groups (TCBF 500 00 5,0 355 55 3,5 1 4 9 62 2,73 273 73 (2,7 50 0 5, 3, 2,7 27 7 (2, 2, (2

RESUMO Um tigre-siberiano (Panthera tigris altaica) de cativeiro, macho, de 15 anos de idade, apresentou hipermetria dos membros pélvicos nos últimos 10 anos, e recentemente, foi observado um nódulo preto e ulcerado caudalmente à orelha direita. O animal foi submetido à cirurgia para remoção do nódulo e morreu durante a recuperação anestésica. À necropsia, outro nódulo infiltrativo, foi detectado caudalmente a orelha direita. Histologicamente, ambos os nódulos correspondiam à neoplasia melanocítica, com células variando de fortemente pigmentadas a amelanóticas, com metástase para linfonodos mediastinais, baço e pulmão. Havia lipofucsinose e corpora amilácea no sistema nervoso central. Os achados macroscópicos e histológicos confirmam o diagnóstico de melanoma cutâneo metastático em um tigre-siberiano adulto de cativeiro.
ABSTRACT A male 15-year-old captive Siberian tiger (Panthera tigris altaica) developed pelvic limb hypermetry over the past 10 years. Recently, an ulcerated black nodule located caudally to the right ear was observed. The animal was submitted to surgery for removing the tumor, but died during anesthetic recovery. At necropsy, another infiltrative nodule was observed caudally to the right ear. Histologically, both nodules corresponded to melanocytic neoplasia, varying from heavily pigmented to amelanotic, with metastasis to mediastinal lymph nodes, spleen and lung. Lipofuscinosis and corpora amylacea were histologically observed in the central nervous system. Macroscopic and histologic findings confirmed the diagnosis of skin metastatic melanoma in a captive adult Siberian tiger.

Abstract: Due to the increasing search for renewable resources, plant fibers have become an alternative when creating new products. Studies demonstrate the potential use of pineapple fibers in composites. The objective of this work was to evaluate the genetic diversity and verify any association between ISSR (Inter Simple Sequence Repeats) bands and quality of pineapple fibers for use in cements in the civil construction. The study analyzed the genetic variability of 11 pineapple genotypes, as well as the possible association of 131 bands from 16 ISSR markers with fiber quality characteristics. Eleven bands were selected based on their high correlations (0.64578* to 0.72457*) with three fiber quality variables. Of these, two bands were purified, sequenced, and blasted against sequences in GenBank at NCBI. These markers can be used in marker assisted selection to genetically improve the quality of pineapple fiber. Bands that returned no hits in the NCBI BLAST search can be deposited as new sequences in the GenBank. Therefore, the SCAR markers, once validated, can be useful in pineapple genetic breeding programs worldwide by using molecular marker assisted selection for fiber resistance, which could subsidize the development of more promising genotypes for industrial use and contribute to the sustainability of this new production sector.

RESUMO O objetivo deste estudo foi caracterizar as doenças dos gatos domésticos provenientes dos casos de necropsia e histopatologia do Hospital Veterinário da Universidade Federal de Minas Gerais (HV/UFMG), de 2005 a 2014. Foram analisados 408 exames de necropsia e 197 de biópsias, segundo o sexo, a faixa etária e a raça. Os diagnósticos mais frequentes incluíram doenças infecciosas/inflamatórias ou parasitárias (22,5%), agentes físicos (18,1%), doenças proliferativas (15,2%) e degenerativas (13,5%). Politraumatismo (10,8%) foi responsável pelo maior número de mortes em felinos, sendo as chances três vezes maiores em animais com até 24 meses de idade (P=0,005 OR 3,47 [IC 95%: 1,40-8,57]). Neoplasias epiteliais corresponderam a 26 diagnósticos, sendo 20 (4,9%) casos de malignidade. A ocorrência de carcinoma e seus subtipos foi 18 vezes maior em gatos idosos (P<0,01 OR 18,15 [IC 95%: 7,41-44,45]). A insuficiência renal crônica foi mais frequente em gatos com mais de 120 meses (P=0,01). Machos apresentaram nove vezes mais chances de desenvolver doenças do trato urinário inferior quando comparados às fêmeas (P=0,001 OR 9,50 [IC 95%: 2,78-32,48]). Em relação às biópsias, animais adultos a idosos foram 10 vezes mais representados (P<0,001 OR 10,8 [IC 95%: 3,22-36,79]).
ABSTRACT The aim of this study was to characterize the diseases of domestic cats based on necropsy and histopathological examinations at the Veterinary Hospital of the Universidade Federal de Minas Gerais (HV/UFMG) from 2005 to 2014. A total of 408 necropsy and 197 biopsy samples were analyzed according to gender, age, and breed. The most frequent diagnoses included infectious/inflammatory or parasitic diseases (22.5%), physical agents (18.1%), proliferative (15.2%), and degenerative (13.5%) diseases. Polytrauma (10.8%) was responsible for the highest number of feline deaths, with the odds three times higher in animals up to 24 months of age (P= 0.005 OR 3.47 [95% CI: 1.40-8.57]). Epithelial neoplasms corresponded to 26 diagnoses, with 20 (4.9%) malignant cases. The occurrence of carcinoma and its subtypes was 18-fold higher in older cats (P< 0.01 OR 18.15 [95% CI: 7.41-44.45]). Chronic renal failure was more frequent in cats over 120 months (P= 0.01). Males were nine times more likely to develop lower urinary tract diseases when compared to females (P= 0.001 OR 9.50 [95% CI: 2.78-32.48]). Regarding the biopsies, adult to elderly animals were ten times more represented (P< 0.001 OR 10.8 [95% CI: 3.22-36.79]).

ABSTRACT The organic extracts from stems, roots and leaves of Tephrosia egregia Sandwith, Fabaceae, provided a new flavone, 5-hydroxy-8-(1",2"-epoxy-3"-hydroxy-3"-methylbutyl)-7-methoxyflavone (1), in addition to eleven known compounds: pongaflavone (2), praecansone B (3), 12a-hydroxyrotenone (4), praecansone A, 2',6'-dimethoxy-4',5'-(2",2"-dimethyl)-pyranochalcone, pongachalcone, maackiain, β-sistosterol and its glucoside, p-cumaric acid and cinnamic acid. The structures of all compounds were established on the basis of spectroscopic methods, mainly 1D and 2D NMR and HRESIMS, involving comparison with literature data. Cytotoxicity of compounds 1–4 was evaluated against AGP-01 (cancerous ascitic fluid), HCT-116 (colon adenocarcinoma), HL-60 (leukemia), PC-3 (prostate carcinoma), SF-295 (glioblastoma) and SKMEL 28 (melanoma) cell lines.

RESUMO O objetivo deste relato é descrever um caso de metaplasia óssea em placenta equina, associada a aborto. Uma égua da raça Campolina, com aproximadamente 19 anos de idade, após múltiplas gestações e sem histórico de alterações reprodutivas, abortou feto com idade aproximada de seis meses. Não foram observadas alterações macroscópicas no feto e na placenta. Microscopicamente, havia substituição do mesênquima de vilosidades coriônicas por tecido ósseo bem diferenciado e parcialmente mineralizado (confirmada pela coloração de von Kossa). Para caracterização do componente colagenoso, foram realizadas colorações de tricrômico de Masson e picrosirius red. O tecido ósseo tinha predominância de colágeno do tipo I. Este é o primeiro relato de metaplasia óssea na placenta equina, associada a aborto no terço médio da gestação, presumivelmente devido à insuficiência placentária.
ABSTRACT The aim of this report is to describe a case of marked osseous metaplasia in the placenta associated with abortion in a mare. A 19-year-old Campolina mare with a history of multiple parturitions and absence of reproductive failure, aborted a fetus with approximately six months of gestation. There were no gross changes in the fetus and the placenta. Microscopically, there was multifocal replacement of fetal connective mesenchyme of the chorionic villi with well differentiated and partially mineralized osseous tissue (confirmed by von Kossa staining). To further characterize the collagenous component of the lesion, sections of the placenta were stained with Masson’s trichrome and Picrosirius red. Osseous tissue deposition had abundance of type I collagen. To the best of our knowledge, this is the first report of osseous metaplasia in the placenta of a mare associated with abortion at mid gestation, presumably due to placentary insufficiency.

The relaxation of coronary arteries by estrogens in the coronary vascular beds of naive and hypertensive rats has been well described. However, little is known about this action in gonadectomized rats. We investigated the effect of 17-ß-estradiol (E2) in coronary arteries from gonadectomized rats, as well as the contributions of endothelium-derived factors and potassium channels. Eight-week-old female and male Wistar rats weighing 220-300 g were divided into sham-operated and gonadectomized groups (n=9−12 animals per group). The baseline coronary perfusion pressure (CPP) was determined, and the vasoactive effects of 10 μM E2 were assessed by bolus administration before and after endothelium denudation or by perfusion with NG-nitro-L-arginine methyl ester (L-NAME), indomethacin, clotrimazole, L-NAME plus indomethacin, L-NAME plus clotrimazole or tetraethylammonium (TEA). The CPP differed significantly between the female and sham-operated male animals. Gonadectomy reduced the CPP only in female rats. Differences in E2-induced relaxation were observed between the female and male animals, but male castration did not alter this response. For both sexes, the relaxation response to E2 was, at least partly, endothelium-dependent. The response to E2 was reduced only in the sham-operated female rats treated with L-NAME. However, in the presence of indomethacin, clotrimazole, L-NAME plus indomethacin or L-NAME plus clotrimazole, or TEA, the E2 response was significantly reduced in all groups. These results highlight the importance of prostacyclin, endothelium-derived hyperpolarizing factor, and potassium channels in the relaxation response of coronary arteries to E2 in all groups, whereas nitric oxide may have had an important role only in the sham-operated female group.

Objetivou-se determinar o melhor nível de inclusão e de substituição das tortas de dendê e amendoim, respectivamente, em dietas para cabritos 1/2 sangue Boer, por meio da avaliação histomorfométrica das papilas ruminais. Foram utilizados 40 cabritos 1/2 sangue Boer, para cada período experimental, machos, não castrados, com idade aproximada de três meses e com peso inicial de 15,01±1,76kg. Os períodos experimentais constaram de 75 dias e 72 dias. As dietas consistiram de volumoso feno de Tifton-85 e de ração em mistura completa, contendo níveis de inclusão da torta de dendê nas proporções de 0,0; 7,0; 14,0; e 21,0% com base na matéria seca; e de mistura completa, contendo níveis de substituição do farelo de soja pela torta de amendoim nas proporções de 0,0; 33,0; 66,0; e 100%, constituindo-se os tratamentos. No epitélio do rúmen, foram avaliadas altura e largura das papilas, assim como densidade papilar e espessura da parede muscular do rúmen. Entre estas, a altura das papilas, no experimento com torta de amendoim, foi a única a sofrer efeito linear decrescente (P<0,0014); as demais variáveis, tanto dos animais alimentados com torta de amendoim quanto daqueles alimentados com torta de dendê, não foram afetadas pela dieta. As médias de altura encontradas foram de 2,6 e 2,3mm para as tortas de amendoim e dendê, respectivamente. Portanto, a inclusão de até 21% de torta de dendê e a substituição de 100% de torta de amendoim no concentrado de cabritos não alteraram a morfometria das papilas ruminais.
The aim of this study was to determine the best level of pies and replacement of palm oil and peanut, respectively, in diets of 1/2 blood Bôer goats from the histomorphometry of the rumen papillae. A total of 40 1/2 blood male, unneutered, aged approximately three months and initial weight of 15.01±1.76kg Bôer goats were used in each experimental period. The experimental periods consisted of 75 days and 72 days. The diets consisted of roughage hay Tifton-85 and total mixed ration containing levels of inclusion of palm kernel cake in the proportions of 0.0, 7.0, 14.0 and 21.0% based on dry matter; and the second experiment consisted of a complete mixture containing substitution levels of soybean meal by groundnut cake in the proportions of 0.0, 33.0, 66.0 and 100%. Epithelial cells were evaluated in the rumen height and width of the papillae, and density and thickness of the papillary muscle of the rumen. Among these, the height of the papillae in the experiment with peanut butter pie was the only one to suffer a negative linear effect (P<0.0014), the other variables, both in animals fed groundnut cake and palm oil, were not affected by the diet. The average heights found were 2.6 and 2.3, for pies, peanut and palm oil, respectively. Therefore, the inclusion of up to 21% palm kernel cake and replacement of 100% peanut cake in the concentrate of kids did not alter the morphology of the rumen papillae.

O estado do Espírito Santo (Brasil) é possui uma extensão litorânea (~ 410 km) com 15 municípios costeiros onde existe atividade pesqueira marinha. Quanto à aquicultura, ela foi introduzida na década de 1980, e desde então houve um grande desenvolvimento dessa atividade. Os primeiros passos, em 1987, foram dados de forma experimental no município de Piúma. Já nos últimos 17 anos, a atividade desenvolveu-se com fins comerciais em outros cinco municípios por meio de projetos com objetivos similares, mas com estratégias diferentes. Em face desse cenário, o presente estudo se mostrou oportuno e possibilita apontar um conjunto de informações dos aspectos econômicos e sociais da pesca e da maricultura no Estado. Essas informações podem contribuir para a definição de áreas estratégicas para o desenvolvimento das atividades de pesca e maricultura de forma sustentável, subsidiando a formulação de políticas de ordenamento do território e orientando as esferas governamentais na tomada de decisões sobre políticas públicas. Como resultado, verificou-se que, além das potencialidades já existentes, há necessidade que o poder público dos municípios e do Estado, estabeleçam políticas de incentivo permanente a maricultura e pesca, como linhas de credito compatíveis com o perfil do pescador tradicional que precisa incrementar a sua renda, tendo em vista a pesca em declínio. Além disso, o acompanhamento das atividades é fundamental para o sucesso das mesmas. Fortalecer o associativismo, identificar gargalos e propor mudanças devem ser os principais itens de pauta da parceria maricultores/pescadores e governo, propiciando o real desenvolvimento da atividade e a redução das desigualdades sociais.
Espírito Santo State (Southeast Brazil) has 15 municipalities in its coastal zone (~140km). Aquaculture was introduced in the 1980s and during this period there was a major development of the activity. Since its beginnings in 1987 activities were experimental, as in Piúma District. In the last 17 years the activity has developed into commercial projects in five other cities. Although projects have similar goals, they diverge in strategies. This study points out a set of information regarding the economic and social aspects of fisheries and aquaculture in the state. Such information can contribute to the definition of strategic areas for the development of fisheries and aquaculture activities in a sustainable manner, supporting the formulation of public policies. Our main result was to identify the need for public institutions of the state and municipalities to establish incentive permanent policies for fishing and aquaculture, with lines of credit consistent with the profile of the traditional fisherman. Moreover, monitoring the activity will be fundamental for its success. Strengthening of the association fishers-government, identification of constrains and adaptation should be the main agenda to enable the development of fisheries/aquaculture sustainability and the reduction of social inequities.

Aiming to evaluate the potential of by-products coming from the production of biodiesel (palm oil, peanuts and sunflower cakes) replacing soybean meal, were evaluated the feeding behavior and bioclimatology of Holstein-Zebu steers fed diets with this byproducts. Were used four rumen canulated Holstein-Zebu steers, kept in individual pens and distributed in a 4 x 4 Latin square with repeated measures on the time. The experiment lasted 88 days and the animals were fed Tifton-85 hay and concentrate ration with soybean meal or one of the following cake: palm kernel, peanuts or sunflower, which constituted the four treatments. Ingestive behavior was assessed by observation and recording of daily time spent on eating, ruminating and idle. The bioclimatological behavior of the animals was evaluated through the following measurements: respiratory frequency (RF), heart frequency (FH) and rectal temperature (RT). The time spent for ingestion and rumination did not differ (p>0.05) between diets, however, animals fed the diet with palm kernel meal, spent more time in idle (p<0.05). There was difference for the physiological parameters only for heart rate (HR), and the diet without additional cake that provided the greatest value. The substitution of soybean meal with palm kernel meal coming from the production of biodiesel in the diet of steers affected the ingestive animal behavior.
Com o objetivo de avaliar o potencial de tortas oriundas da produção de biodiesel (dendê, amendoim e girassol) em substituição ao farelo de soja, avaliou-se o comportamento ingestivo e parâmetros fisiológicos de novilhos Holandês x Zebu submetidos a dietas contendo estes subprodutos. Foram utilizados quatro novilhos Holandês x Zebu, fistulados no rúmen, mantidos em baias individuais e dispostos em um quadrado latino 4 x 4 repetido no tempo. O experimento teve duração de 88 dias e os animais foram alimentados com feno de Tifton-85 e mistura concentrada com farelo de soja, tortas de dendê, amendoim e girassol, que constituíram os quatro tratamentos. O comportamento ingestivo foi avaliado por observação e registro dos tempos diários despendidos com alimentação, ruminação e ócio. O comportamento bioclimatológico dos animais foi avaliado por intermédio das seguintes medições: frequência respiratória (FR), frequência cardíaca (FC) e temperatura retal (TR). Não houve diferença entre as dietas para o tempo despendido tanto na ingestão, como na ruminação (p>0,05), entretanto, os animais que consumiram a dieta com torta de dendê despenderam mais tempo em ócio (p<0,05). Nos parâmetros fisológicos, ocorreu diferença apenas para frequência cardíaca (FC), sendo a dieta sem torta adicional a que proporcionou o maior valor. A substituição do farelo de soja pela torta de dendê oriunda da produção do biodiesel na dieta de novilhos afetou o comportamento ingestivo dos animais.

This work introduces a new data transmission system in which the main blocks, coding, modulation and channel are designed on a Riemannian manifolds. An intrinsic algebraic structure to the manifolds (surface), the homology group will be used to compose an error corrector code, a partition on the surface extracted from the embedding of a graph, which will compose the modulation design, and the channel design is the result of an association rule applied to the embedded graph. Mathematical subject classification: Primary: 06B10; Secondary: 06D05.

The first epidemiologic inquiry to Brucella abortus (B. abortus) and Brucella ovis (B. ovis) was carried out in sheep from Uberlândia county, MG. A total of 334 blood serum samples of sheep from both sexes and different ages and breeds were collected in 12 farms. An epidemiologic questionnaire was applied for each farm. Tests for B. abortus and B. ovis antibodies were Buffered Acidified Antigen and Complement Fixation, respectively. None of the sheep was reactive to B. abortus and B. ovis; however, the adoption of sanitary measures is important to avoid the introduction of infections caused by these bacteria.

Avaliou-se a regeneração óssea de auto-enxerto, considerado "padrão ouro" da crista ilíaca associado à terapia celular da medula óssea em coelhos. Foi criado um defeito ósseo de 10x5x5mm na mandíbula de 28 coelhos, distribuídos em grupo-controle com, 14 animais, reparados com auto-enxerto de crista ilíaca, e grupo experimental com, 14 animais, em que o auto-enxerto foi associado a células mononucleares da medula óssea autógena do fêmur. Foram realizadas radiografias semanais da região operada e análise histológica em sete animais de cada grupo aos 15 e em sete de cada grupo aos 30 dias do pós-operatório. Houve aumento gradativo da densidade óssea, e 85,7% (6/7) dos animais do grupo experimental e 42,8% (3/7) do grupo-controle apresentaram formação de ponte óssea 28 dias após a cirurgia. Na análise histopatológica aos 15 dias, os enxertos foram facilmente visualizados e a atividade das células fagocitárias foi intensa. Já aos 30 dias, a visualização foi mais difícil e, quando possível, apenas um resquício foi visualizado. Os resultados sugerem que a adição de células mononucleares da medula óssea favorece a regeneração do auto-enxerto em defeitos mandibulares de coelhos.
The objective of this study was to investigate the bone regeneration of a "gold standard" (autograft) from iliac crest associated with cellular therapy in rabbits. A bone defect was created with 10x5x5mm in 28 rabbit mandibles. The control group animals (n=14) were repaired with autograft of iliac crest and the experimental group animals (n=14) received iliac crest autograft in association with mononuclear cells from the bone marrow of the femur. Weekly radiographs were taken of the surgery region and histological analyses was performed in seven animals in each group at 15 days and in seven animals of each group at 30 days after the surgery. A gradual increase of bone density was observed and the experimental animals presented the bone bridge in 85.7% (6/7) of the cases, while only 42.8% (3/7) of the animals in the control group presented this structure 28 days after the surgery. The histopathological parameters analyzed did not show any statistical difference between the control and experimental group in 15 and 30 days of analysis. The results suggest that the mononuclear cells from the marrow bone can better support the autograft regeneration in mandible defects in rabbits.
