Abstract Brazil is renowned for its extensive plant biodiversity, with emphasis on Cymbopogon, C. citratus and C. nardus, with broad antimicrobial potential. Candidemias caused by Candida albicans are highly prevalent in immunosuppressed individuals and are associated with infections by biofilms on medical devices. The aim of this study was to evaluate the antimicrobial potential of essential oils C. citratus and C. nardus against C. albicans in planktonic and biofilm forms. Essential oils were obtained by hydrodistillation and chemical composition evaluated by GC-FID and GC-MS. The minimum inhibitory concentration was determined by the broth microdilution method and the synergy effect of essential oils and amphotericin B were evaluated by the checkerboard test. Biofilm activity was determined by the XTT assay. Cytotoxicity assays performed with VERO cells and molecular docking were performed to predict the effect of oil interaction on the SAP-5 enzyme site. The results showed activity of essential oils against planktonic cells and biofilm of C. albicans. Furthermore, the oils had a synergistic effect, and low cytotoxicity. Molecular docking showed interaction between Cadinene, Caryophyllen oxide, Germacrene D with SAP-5. The results indicate that Cymbopogon spp. studied are anti-Candida, with potential for further application in therapy against infections caused by C. albicans. biodiversity C devices forms GCFID GC FID GCMS.

Abstract Although biofloc technology is already recognized as advantageous and practical for aquaculture for the effects of maintaining water quality and improving the health status and resistance of cultivated animals against pathogens, little is known about the way of action involved. This study aimed to evaluate the performance of bacterial groups as inducers in the formation of flocs compared to a system with spontaneous formation. Therefore, three microsystems were built in 3L tanks with constant aeration to induce the biofloc aggregation with addition of bacterial consortiuns with differentiated functions. It was used a control, without addition of bacterial consortium; B1 with addition of probiotic bacteria consortium; and B2, with adding nitrifying bacteria consortium. During the experimental period were evaluated physicochemical variables and quantifications of bacterial cultivable groups: Heterotrophic Bacteria and Vibrio. Also was the microscopic characterization of the flakes and tests of antimicrobial activity against pathogenic bacteria. Systems B1 and B2 showed promising results in relation to control (spontaneous bioflocs), showing more homogeneous flake formation, antimicrobial activity against the tested pathogens and greater biological diversity in the systems. The bacteria used in these tests were able to optimize the formation of microbial aggregates, showing potential for application in cultivation systems, in order to obtain improvements in productivity. involved Therefore L functions consortium B Vibrio bioflocs, bioflocs , bioflocs) systems aggregates productivity

Abstract: This study presents the first record of Elops smithi for northern Brazil. The evidence suggests this species is being misidentified incorrectly as Elops saurus in estuaries of the Western Atlantic Ocean. Here, morphological, molecular, and cytogenetic evidence identified all ladyfish specimens from one estuary in the region as E. smithi. Thus, at least Elops smithi occurs in the northern coast of Brazil and it is recommended that specimens from this region identified as E. saurus be further investigated with genetic and cytogenetic tools in order to assure a correct species identification.

RESUMO Objetivou-se verificar os efeitos de diferentes protocolos anestésicos usados durante a eletroejaculação (EEJ) em tatus-peba (Euphractus sexcinctus). Quatro animais sexualmente maduros foram contidos fisicamente e submetidos à coleta de sêmen por EEJ, seguindo três tratamentos: o grupo controle consistiu do não uso de anestesia; nos outros, foram administradas combinações anestésicas de xilazina/cetamina/propofol, ou butorfanol/cetamina/propofol. Para cada grupo, foram conduzidos 12 procedimentos de EEJ. O sêmen foi avaliado para volume, cor, aspecto, motilidade, concentração de espermatozoides, morfologia, viabilidade e integridade funcional da membrana. A mais alta eficiência (100% de ejaculados) foi alcançada quando o grupo controle foi utilizado; a associação de cetamina/xilazina/propofol forneceu apenas 11 ejaculados de um total de 12 tentativas (de eficiência 91,6%), enquanto apenas quatro ejaculados (eficiência de 33%) foram obtidos com butorfanol/cetamina/propofol (P < 0,05). Ambos os protocolos forneceram rápida indução e relaxamento suficientes para executar a EEJ. Na utilização de butorfanol/cetamina/propofol, os animais se recuperaram em 16,5±1,5min, um tempo mais curto do que no uso de xilazina/cetamina/protocolo de propofol, 20,7±1,0min (P>0,05). O volume de sêmen e a concentração espermática obtidos no uso da associação xilazina/cetamina/propofol foram significativamente maiores do que os verificados para o protocolo butorfanol/cetamina/propofol. Em conclusão, a associação de cetamina/xilazina/propofol é indicada para anestesia de tatus-peba submetidos à EEJ.

ABSTRACT The aim was to verify the effects of different anesthetic protocols used during electroejaculation (EEJ) in six-banded armadillos (Euphractus sexcinctus). Four sexually matured animals were physically restrained and subjected to semen collection by the EEJ following three treatments: The control group consisted of no use of anesthesia; in the others, the anesthetic combinations xylazine/ketamine/propofol or butorphanol/ ketamine/propofol were administered. For each group, twelve procedures were conducted for EEJ. Semen was evaluated for volume, color, aspect, motility, sperm concentration, morphology, viability, and functional membrane integrity. The highest efficiency (100% ejaculates) was achieved when the control group was used; the xylazine/ketamine/propofol association provided only 11 ejaculates from a total of 12 attempts (91.6% efficiency), while only 4 ejaculates (33% efficiency) were obtained with butorphanol/ketamine/propofol (P<0.05). Both protocols provided rapid induction and relaxation enough to perform the EEJ. In the use of butorphanol/ketamine/propofol, the animals recovered at 16.5±1.5min, a time shorter than in the use of xylazine/ketamine/propofol protocol, 20.7±1.0min (P>0.05). The semen volume and sperm concentration obtained in the use of xylazine/ketamine/propofol association were significantly higher than those verified for butorphanol/ketamine/propofol protocol. In conclusion, the xylazine/ketamine/propofol association is indicated for anesthesia of six-banded armadillos submitted to EEJ.

Celtis iguanaea (Jacq.) Sargent (Cannabaceae) é uma das espécies nativas do cerrado brasileiro, sendo amplamente utilizada na medicina popular para o tratamento de dispepsia. O objetivo do presente trabalho foi avaliar o efeito gastroprotetor do extrato hexânico das folhas de Celtis iguanaea (Jacq.) Sargent (EH) em modelos de secreção e de lesões gástricas. A atividade antisecretória do extrato hexânico das folhas de Celtis iguanaea (EH) foi avaliada no modelo de mucosa isolada de Rana catesbeiana e pelo modelo de ligadura pilórica em camundongos. A avaliação da atividade anti-ulcerogênica do EH foi determinada no modelo de úlceras gástricas induzidas por indometacina e ligadura pilórica. Quando a mucosa de Rana catesbeiana isolada foi incubada com o EH, a secreção de H+ foi reduzida em comparação com o valor basal (15,58 ± 1,99 µEq H+/g/15 min). O tratamento com o EH reduziu o índice de lesões na úlcera induzida por indometacina e ligadura pilórica. O EH também reduziu o volume de secreção, a acidez total, e aumentou o pH gástrico. A administração intraduodenal reduziu a secreção gástrica produzida por betanecol ou histamina. A eficácia anti-ulcerogênica e antisecretória do EH neste estudo, sugere um mecanismo anticolinérgico e antihistaminérgico ou interrupção de eventos intracelulares que estão ligados à secreção ácida.

The Celtis iguanaea (Jacq.) Sargent (Cannabaceae) is one of the native species of the Cerrado region of Brazil widely used in folk medicine to treat dyspepsia. The objective of the present study was to evaluate the gastroprotective effect of the Celtis iguanaea (Jacq.) Sargent (HE) hexane leaf extract in the lesion and gastric secretion models.Antiulcerogenic activity of the Celtis iguanaea (HE) hexane leaf extract was observed with the experimental models, such as indomethacin and pyloric ligation-induced gastric ulcers. In order to evaluate the antisecretory activity of this extract, isolated Rana catesbeiana mucosa and pyloric ligation in mice were used. The HE treatment reduced the lesion index of indomethacin and pyloric ligation-induced ulcer. This extract also reduced the gastric acid secretion and total acidity (increasing the gastric pH) in mice. The secretion of H+ was reduced in the basal values (15.58 ± 1.99 µEq H+/g/15 min) when isolated Rana catesbeiana mucosa was incubated with HE. Intraduodenal administration of HE reduced the gastric secretion produced by bethanecol or histamine. The antiulcerogenic and antisecretory efficacy of HE in this study suggest anticholinergic and antihistaminergic mechanism or interruption of intracellular events that are linked to acid secretion.

Nas últimas décadas, as proteínas de fase aguda (PFAs) tornaram-se biomarcadores de escolha em medicina humana para identificação e monitoração de doenças. Não há razão para imaginar que tais pesquisas clínicas não sejam igualmente úteis na medicina veterinária. Com o objetivo de verificar a importância das PFAs como biomarcadores de doenças inflamatórias em bovinos, determinou-se o proteinograma sérico, por meio da técnica de eletroforese SDS-PAGE, com interesse especial nas PFAs. Foram utilizados 30 animais, distribuídos em dois grupos: 15 bovinos sadios e 15 bovinos doentes (cinco com mastite estafilocócica, cinco com fotossensibilização e cinco com onfaloflebite). Os animais foram submetidos a colheitas diárias de sangue durante sete dias, enquanto internados no Hospital Veterinário da Unesp, Campus de Jaboticabal. Ceruloplasmina e haptoglobina apresentaram elevação significativa em animais acometidos por mastite, fotossensibilização e onfaloflebite (275,17% e 343,71%; 175,17% e 230,19%; 114,47% e 144,47%, respectivamente). A α1-glicoproteína ácida foi um bom biomarcador apenas em animais com mastite e fotossensibilização, elevando, respectivamente, suas concentrações séricas em 198,14% e 145,89%. Fibrinogênio mostrou-se um indicador confiável apenas em bovinos com mastite, com elevação de 146,5% em relação ao grupo sadio. Ficou clara a diferença na responsividade de distintas PFAs frente a diferentes estímulos inflamatórios. Ceruloplasmina e haptoglobina foram biomarcadores mais sensíveis e, portanto, mais confiáveis entre as PFAs estudadas nessa espécie.

Over the last few decades acute phase proteins (APP) have become the biomarkers of choice in human medicine to identify and monitor inflammation and infection. There is no reason to suppose that clinical investigations in veterinary medicine would not be equally assisted by APP assays. Aiming to verify the importance of APPs as biomarkers of inflammatory diseases in domestic cattle, serum protein profiles, especially APPs, were determined through the SDS-PAGE electrophoresis technique. Thirty animals were allotted in two groups: 15 healthy cattle and 15 clinically ill cattle (5 with staphylococcal mastitis, 5 with photosensitization and 5 with onphalophlebitis). All animals were submitted to daily blood sampling during 7 days, while interned in the Veterinarian Hospital from UNESP, Jaboticabal campus. Ceruloplasmin and haptoglobin were significantly elevated in animals with mastitis, photosensitization and onphalophlebitis (275.17% and 343.71%; 175.17% and 230.19%; 114.47% and 144.47%, respectively). α1-acid glycoprotein behaved as a good biomarker only in animals with mastitis and photosensitization, elevating respectively 198.14% and 145.89% of their serum levels. Fibrinogen was a reliable indicator only in animals undergoing mastitis, with a raise of 146.5%. The diverse responsiveness of different APP under distinct inflammatory stimuli was clear. Ceruloplasmin and haptoglobin were more sensible and, therefore, reliable biomarkers to the diseases studied in this species.

Soluções hiposmóticas com diferentes concentrações (0, 50, 100, 150, 200mOsm/L) foram testadas para a avaliação funcional da membrana espermática de catetos (n=13). Foi verificado que o número de espermatozoides reagidos diminuía (P<0,05) de acordo com o aumento da osmolaridade do meio. A maior porcentagem (71,8%) de espermatozoides reagidos, bem como a menor variação nas respostas osmóticas, foi detectada com o uso de água destilada (0mOsm/L) (P<0,05), a qual também apresentou a menor variação nos resultados, de acordo com os erros padrão verificados. Em conclusão, a água destilada aparenta ser uma solução adequada para o uso no teste hiposmótico para sêmen de catetos.

O presente estudo objetivou analisar os efeitos do treinamento funcional com cargas (TFC) na composição corporal de mulheres fisicamente inativas. Vinte mulheres (25.70 ± 4.20 anos) foram designadas aleatoriamente para os grupos experimental (GE, n = 10) e controle (GC, n = 10), tendo o GE realizado 12 semanas de TFC, enquanto o GC não recebeu qualquer intervenção. As variáveis antropométricas avaliadas em ambos os grupos foram: massa corporal (MC), estatura, índice de massa corporal (IMC), massa de gordura absoluta, massa corporal magra (MCM) e percentual de gordura (%G). Os testes t de Student independente e pareado foram utilizados para a comparação das médias inter e intra-grupos experimental e controle (p < .05). O GE apresentou reduções significativas nos valores de %G (p < .001), enquanto o GC aumentou seus níveis de MCM (p < .001), IMC (p < .001) e MC (p = .021). Os resultados indicaram que após de 12 semanas o TFC reduz os níveis de gordura corporal, mas não promove aumentos de MCM em mulheres fisicamente inativas.

This study aimed to analyze the effects of the functional strength training (FST) on body composition of physically inactive women. Twenty women aged between 19 and 34 years old (25.70 ± 4.20 yr.) were randomly assigned to experimental (EG, n = 10) and control group (CG, n = 10). The EG performed 12 weeks of FST, while CG did not receive any intervention. The anthropometric variables evaluated in both groups were: body mass (BM), height, body mass index (BMI), absolute fat mass (AFM), lean body mass (LBM) and fat percent (%F). The paired and independent samples t tests were used to identify modifications between and within experimental and control groups (p < .05). The EG decreased %F values (p < .001), while CG increased the LBM (p < .001), BMI (p < .001) and BM (p = .021). Results showed that after 12 weeks FST can be useful to reduce body fat mass, but it doesn’t promote increases on LBM of physically inactive women.
