Abstract The cardiovascular disease is the main cause of worldwide death. This profile is potentialized by the increased severity of infections in people with obesity, type 2 diabetes and hypertension. Children and adolescents are target groups for the prevention of non-communicable diseases. The Developmental Origins of Health and Disease concept points that perinatal conditions are an important risk factor to development of non-communicable disease in adulthood. In this context, the present review identifies perinatal factor that induces precocious cardiovascular risk factors, related with cardiometabolic syndrome. The low or high birth weight and caesarean delivery are risk factors that induce increased occurrence of cardiovascular risk biomarkers in children and adolescents, while the breast feeding or feeding with breast milk from the birth until two years-old is a protector strategy. Evaluation of perinatal conditions associated with precocious identification of cardiovascular risk factors in children and adolescents is an efficient strategy to prevent and control cardiovascular mortality; through interventions, as lifestyle changes during vulnerable windows of development, able to set up the risk to cardiometabolic disease. death obesity hypertension noncommunicable non communicable diseases adulthood context syndrome yearsold years old mortality interventions

RESUMO Entre outubro de 2016 e outubro de 2017, 63 urólitos felinos foram analisados na Universidade Federal de Goiás (UFG), usando-se tanto análise química quanto espectroscopia por energia dispersiva (EDS). O tipo de mineral mais encontrado foi o estruvita (53,9%), seguido pelo urato (39,7%), oxalato de cálcio (30,1%) e fosfato de cálcio (25,3%). Cálculos contendo xantina, cistina e sílica não foram observados. Urólitos classificados como simples comprometeram um total de 34/63. Entre os 42 animais presentes no estudo, 26 eram machos e 16 eram fêmeas. Dos animais comprometidos, 14,4% eram de raças puras, sendo observadas as raças Persa, Himalaio, Siamês e Angorá. Gatos com idade entre 25-72 meses foram mais frequentemente diagnosticados com urólitos. Os sinais clínicos variaram entre sinais sistêmicos e urinários, sendo anorexia, vômito, hematúria e disúria os mais encontrados. Todos os pacientes eram castrados, e 34 deles não tinham acesso à rua. Histórico familiar era desconhecido em quase 100% dos casos. Os resultados observados no presente estudo servem como base para comparações futuras relacionadas à epidemiologia da litíase urinária no Brasil, especialmente em espécies felinas.

ABSTRACT Between October 2016 and October 2017, 63 feline uroliths were analyzed at Universidade Federal de Goiás (UFG) by using both chemical analysis and energy dispersive spectroscopy (EDS). The most frequent mineral type found was struvite (53.9%), followed by urate (39.7%), calcium oxalate (30.1%) and calcium phosphate (25.3%). Calculus containing xanthine, cystine and silica were not observed. Uroliths classified as simple, comprised a total of 34/63. Amongst the 42 animals present in the study, 26 were male and 16 were female. Pure breed animals comprised 14.4% of the total, and the breeds observed within the study were the Persian, Himalayan, Siamese, and Angora. Cats between 25-72 months old were more frequently diagnosed with uroliths. The clinical signs varied between systemic and urinary signs and the most found were anorexia, vomiting, hematuria and dysuria. All patients were either spayed or neutered and 34 patients had no outdoor access. Familial information was unknown in almost 100% of the cases. The results observed in the present study serve as a basis for future comparisons related to the epidemiology of urinary lithiasis in Brazil, especially for the feline species.

Abstract This work aimed to compare the production of collagenolytic proteases produced by M. subtilissimus UCP1262 in submerged fermentation (SF) and solid-state fermentation (SSF) as well as extracting in aqueous two-phase system (ATPS). Collagenolytic protease production was performed in using MS-2 culture medium (SF) and soybean bran as substrate (SSF). Subsequently, the fermented liquid from both fermentations were used for the extraction of enzyme by ATPS, it was verified the influence of different variables from a factorial design 23. In SSF the highest protease and collagenolytic activities were achieved with 362.66 U/mL and 179.81 U/mL, respectively. When compared with SF (26.33 and 18.70 U/mL) higher values were obtained in the activities. The protease partitioning from SF and SSF in ATPS showed a similar profile showing higher affinity for the polymer rich phase. The highest value for the response variable purification factor (3.49) was obtained in the system using SSF. Thus, SSF shows promise as a bioprocess for extracellular production of collagenolytic proteases, using of soybean bran as substrate had used sustainable raw material, aiming application this possible enzyme in the treatment of burns and postoperative scarring.

Abstract: En | Text: En | PDF: En

The scientific publication landscape is changing quickly, with an enormous increase in options and models. Articles can be published in a complex variety of journals that differ in their presentation format (online-only or in-print), editorial organizations that maintain them (commercial and/or society-based), editorial handling (academic or professional editors), editorial board composition (academic or professional), payment options to cover editorial costs (open access or pay-to-read), indexation, visibility, branding, and other aspects. Additionally, online submissions of non-revised versions of manuscripts prior to seeking publication in a peer-reviewed journal (a practice known as pre-printing) are a growing trend in biological sciences. In this changing landscape, researchers in biochemistry and molecular biology must re-think their priorities in terms of scientific output dissemination. The evaluation processes and institutional funding for scientific publications should also be revised accordingly. This article presents the results of discussions within the Department of Biochemistry, University of São Paulo, on this subject.

RESUMO O estudo teve como objetivo avaliar o enraizamento e alguns caracteres fisiológicos em estacas de Lantana camara L. (Verbenaceae) em diferentes concentrações de ácido indolbutírico (AIB) e sua associa- ção com os fungos micorrízicos arbusculares (FMA) Claroideoglomus etunicatum (W.N. Becker & Gerd.) C. Walker & A. Schüssler e Gigaspora albida N.C. Schenck & G.S. Sm. Utilizou-se o delineamento experimental inteiramente casualizado em esquema fatorial 3 × 3 com três repetições, sendo o primeiro fator composto pelos FMA e o segundo fator pelas doses de AIB (0; 1,0 e 1,5 mg.mL-1). Os resultados mostraram que a presença de FMA no substrato, assim como o AIB, isolados ou de forma interativa estimulam o enraizamento e alguns caracteres fisiológicos de estacas de L. camara.

ABSTRACT The objective of this study was to evaluate the rooting and some physiological characteristics of Lantana camara L. (Verbenaceae) stakes in different concentrations of indolebutyric acid (IBA) and its association with the arbuscular mycorrhizal fungi (AMF) Claroideoglomus etunicatum (W.N. Becker & Gerd.) C. Walker & A. Schüssler e Gigaspora albida N.C. Schenck & G.S. Sm. The experimental design was completely randomized in a 3x3 factorial scheme with three replicates, where the first factor was the AMF and the second factor by doses of IBA (0; 1.0 and 1.5 mg .mL-1). The results showed that the presence of AMF in the substrate, as well as the IBA, isolated or in association stimulates the rooting and some physiological characters of L. camara cuttings.

RESUMO Objetivou-se com este trabalho comparar biomecanicamente os posicionamentos dorsal e medial da placa bloqueada na artrodese do carpo em cães. Para isso, foram utilizados sete pares de membros torácicos de cães eutanasiados por razões não relacionadas ao estudo, em que sete membros foram estabilizados com placa dorsal, e seus respectivos pares com placa em posicionamento medial. Os membros com as articulações radiocarpometacarpianas estabilizadas cirurgicamente foram submetidos a ensaio de compressão axial em máquina universal de ensaios de materiais, e os dados de limite de elasticidade, rigidez estrutural, carga máxima e carga no momento da fratura dos posicionamentos foram comparados por meio do teste de Student-Newman-Keuls, a um nível de significância de 5%. Todos os membros foram fraturados no terço distal do terceiro metacarpo; nos membros com placa dorsal, a fratura ocorreu distal ao orifício distal e, nos membros com placa medial, a fratura ocorreu no último orifício dos metacarpos dois e três. Não houve dobra ou quebra de placas e parafusos e não houve diferença significativa entre os posicionamentos dorsal e medial dos implantes quanto aos parâmetros avaliados.

ABSTRACT The aim of this study was to compare biomechanically the dorsal and medial positions of the locking plates on carpal arthrodesis in dogs. For this, seven pairs of thoracic limbs of dogs were used, in which seven limbs were stabilized with dorsal plate and seven limbs with plate in medial positioning. The members with the surgically stabilized radiocarpal-metacarpal joints were submitted to axial compression testing in a universal testing machine and the yield load, structural rigidity, maximum load and ultimate load of the positioning were compared by Student-Newman-Keuls test at a significance level of 5%. All members fractured in the distal third of the third metacarpal, in the limbs with dorsal plate the fracture occurred distal to the distal hole and in the members with medial plate the fracture occurred in the last hole of the metacarpals two and three. There was no bending or broken implants. There was no significant biomechanical differencebetween the dorsal and medial positions of the implants.

ABSTRACT The Pantaneira breed is in danger of extinction. Due to the lack of scientific information on the Pantanal milk potential, this work had the objective of determining the lactation period and a physical-chemical composition of the milk of cows in second order of parturition. The animals were managed in a pasture system rotated in mombaça grass (Panicum maximum) and individually supplemented with concentrate. The milking was performed mechanically twice a day and the milk weighed daily. The physical-chemical characteristics of the milk were evaluated by the ultrasound method and the lactation curves were estimated using the univariate parameter. The average milk yield was 5.34kg/milk/ day and the fat, protein, lactose and total non-fat solids contents were 5.3, 3.7, 6.0 and 10.7%, respectively. Lactation of the cows in second order of calving ended naturally at 180 days and the peak of milk production was reached between 51 and 60 days. Furthermore, there was no difference in milk composition in the different lactation periods.

RESUMO A acropostite-fimose é um processo inflamatório da extremidade do prepúcio, diagnosticada com frequência em touros. O presente estudo objetivou avaliar o exame ultrassonográfico na definição da viabilidade do folheto prepucial interno (FPI) e na evolução clínica do pós-operatório, após o emprego de fios de categute ou poliglactina na hemostasia e de algodão ou poliglactina na confecção de sutura padrão Donatti empregada para fixar o FPI à pele prepucial no transoperatório da acropostite-fimose em touros. A sutura utilizada foi captonada ou não captonada, e os animais submetidos ao procedimento cirúrgico apresentavam no mínimo dois terços do FPI viável. Os touros foram alocados, aleatoriamente, em quatro grupos contendo nove animais cada, de acordo com o fio empregado na hemostasia e na confecção da sutura padrão Donatti. O exame ultrassonográfico mostrou-se importante na indicação ou não do tratamento cirúrgico da acropostite-fimose e possibilitou localizar lesões, mensurar a área de reação tecidual e identificar lesões profundas e pontos de estreitamento do FPI. Os animais de GII apresentaram edema mais discreto, observando-se diferença significativa (P<0,05) entre GII e os grupos GI, GIII e GIV. A ocorrência de hiperemia no sétimo dia de pós-operatório também foi menor nos touros do grupo GII, ocorrendo diferença significativa (P<0,05) entre GII e os grupos GI e GIII. A sutura empregando o dispositivo de látex (cápton) e o emprego do fio de poliglactina apresentaram-se como medidas benéficas, resultando em menor número de complicações pós-operatórias.

ABSTRACT Acropostitis-Phimosis is an inflammatory process of the extremity of the prepuce, frequently diagnosed in bulls. The present study aimed to evaluate ultrassound exams in the definition of viability of the internal layer of prepuce and the postoperative clinical evolution. This evaluation is after the employment of catgut or poliglactin threads in homeostasis, and cloth or polyglactin threads in confection of the standard suture, Donatti, used to fix the internal layer of prepuce to the preputial in the postoperative of acropostitis-phimosis in bulls. The suture was captonated and non-captonated and the animals conducted to the surgical procedure showed at least 2/3 of viability of the internal layer of prepuce. The bulls were randomly allocated in four groups, each one containing nine animals, according to the thread used in homeostasis and confection of the Donatti standard suture. Ultrassound was shown to be important in the indication or not of the surgical treatment of acropostitis-phimosis and allowed the identification of lesions, measurement of areas of tissue reaction and locate deep lesions and narrowing points of internal layer of prepuce. The employment of latex device (capton) in suture and the employment of polyglactin thread 910 were shown as beneficial measures, resulting in a lower number of postoperative complications.

RESUMO: A análise hematológica fornece informação confiável sobre a saúde dos animais. É uma variável importante na avaliação da capacidade adaptativa e produtiva das raças sob condições ambientais desfavoráveis. É uma avaliação que aliada a outros fatores genéticos, ambientais e de manejo pode se tornar cada vez mais útil para a sustentabilidade futura da agricultura convencional em um ambiente quente. A capacidade adaptativa é afetada por alguns fatores como raça, gestação e lactação. Portanto, o perfil hematológico é um indicador importante da saúde e produção animal. O objetivo deste estudo foi realizar a análise hematológica comparativa de ovelhas Morada Nova e Santa Inês (ovelhas nativas do Brasil) em todos os estágios reprodutivos. Foram utilizadas 20 ovelhas Santa Inês e 20 Morada Nova distribuídas em um delineamento inteiramente casualizado, em parcelas subdivididas e medidas repetidas no tempo. Para a análise do sangue, foram coletadas amostras por venopunção jugular a cada 14 dias, sempre colhidas pela manhã, antes que os animais fossem soltos no pasto. A raça Morada Nova apresentou maior teor de hemoglobina e contagem total de leucócitos que a raça Santa Inês. Em relação à influência da gestação e do puerpério sobre o eritrograma, observou-se que houve um incremento dos valores da contagem dos eritrócitos, hematócrito e hemoglobina até o terço médio da gestação, reduzindo no final da gestação e restabelecendo novamente no período puerperal. Foi verificado um aumento na relação neutrófilo/linfócito indicando que ovelhas no final da gestação, no pós-parto e puerpério estavam sob condição de estresse comparado com os outros estágios reprodutivos. As proteínas plasmáticas totais também aumentaram durante o período gestacional para compensar os altos requisitos nutricionais do feto, e estes níveis permaneceram elevados até ao final da fase de puerpério quando os cordeiros foram desmamados. A gestação e o puerpério influenciaram todos os índices eritrocitários com alteração da contagem total de leucócitos.

ABSTRACT: Hematologic analysis provides reliable information on the health status of animals. It is an important variable in the assessment of adaptive and productive capacity of breeds under unfavorable environmental conditions. It is an assessment that combined with other genetic and environmental factors and management can become useful for the future sustainability of mainstream agriculture in a hot environment. Adaptive capacity is affected by some factors such as breed, pregnancy and lactation. Therefore, hematological profile is an important indicator of animal health and production. The objective of this study was to perform the comparative hematological analysis of Santa Inês and Morada Nova breeds (native ewes from Brazil) in all different reproductive stages. Twenty Santa Ines and 20 Morada Nova sheep distributed in a completely randomized design in a split-plot arrangement over time were used. To obtain blood counts, blood samples were collected by jugular venipuncture every 14 days, always in the morning, before the animals were released into the pasture. The Morada Nova breed had higher hemoglobin and total leukocyte count than Santa Inês breed. Regarding the influence of pregnancy and puerperium on the eritrogram, there was an increment in red blood cell, hemoglobin and packed cell volume of both breeds in middle pregnancy. However, had a reduction in late pregnancy. There were a reestablishment of the blood cell counts during the puerperium period. It was verified an increase on neutrophil: lymphocyte ratio indicated that ewes in the late pregnancy, postpartum and puerperium were under stress conditions compared to others reproductive stages. The total plasma proteins also increased during this period to compensate for the high nutritional requirements of the fetus, and these levels remained high until the end of the puerperal phase, when the lambs were weaned. The pregnancy and puerperium influenced all erythrocyte indices and changed the total leukocyte count.

ABSTRACT Parasitic isopods of fishes usually show wide distribution and low host specificity. This study investigated the occurrence of gill parasites in 120 specimens of spotted goatfish Pseudupeneus maculatus, marine fish of great economic importance for fishery community. The fish were captured monthly in the Coast of Pernambuco State, Northeast Brazil, between October 2012 and September 2013. Eleven isopods were found and identified as Rocinela signata. We observed lower infections in the gills of P. maculatus (prevalence 8.3%, mean intensity 1.6±0.3 and mean abundance 0.1±0.3) when compared to other studies of different host fishes from geographically close locations. This parasite has been reported from a wide variety of fish species, not only in Brazil, but also in the eastern Atlantic and the Pacific oceans. This is the first report of R. signata in spotted goatfish.

ABSTRACT Neoleucinodes elegantalis is an important tomato pest in Brazil, occurring throughout the country and resulting in economic losses in agriculture. In several species, biogeographic studies in Brazil indicate the structuring of populations, following the refuge model, with a split between the populations of the northeast and the southeast regions of Brazil. The objective of this work was to analyze the phylogeography of N. elegantalis in Brazil, understanding its population structure and the demographic patterns. Larvae were collected from eight locations throughout Brazil, and the mitochondrial cytochrome c oxidase subunit 1 gene was analyzed. A total of 628 bp in 51 individuals were obtained, showing 12 haplotypes with a haplotype diversity of 0.836. Spatial analysis of molecular variance (SAMOVA) and cluster analysis showed two populations, indicating population structuring between individuals from the northeast (population 1) and southeast (population 2) regions of Brazil. Phylogenetic analysis indicated that the clades corresponding to the groups defined by SAMOVA have a divergence time of 0.2–0.5 million years, suggesting isolation during climatic events and a separation of the two populations coinciding with the predicted refuges to the Atlantic forest.

Os efeitos de fontes de lipídios na dieta de poedeiras sobre o desempenho produtivo e a qualidade do ovo foram verificados em dois experimentos. Foram utilizados quatro tratamentos, definidos de acordo com a fonte lipídica adicionada nas rações: óleo de soja, óleo de girassol, óleo de linhaça e ração controle (sem adição de óleo). Os experimentos foram realizados com poedeiras de 20 e 54 semanas de idade, respectivamente, com duração de oito semanas. Avaliaram-se os parâmetros produtivos - consumo de ração, conversão alimentar, produção e peso dos ovos - e de qualidade do ovo - porcentagens de gema, albúmen e casca, sólidos da gema, unidades Haugh, pH do albúmen, e cor da gema. Somente o peso do ovo de poedeiras jovens foi afetado pela inclusão de óleos vegetais na ração. Esses ovos apresentaram maior peso e maior porcentagem de gema que os produzidos pelas poedeiras jovens alimentadas com ração-controle. Concluiu-se que a utilização de diferentes fontes de lipídios na ração de poedeiras não altera o desempenho produtivo e a qualidade interna dos ovos, com exceção do peso do ovo de poedeiras novas, que aumenta com a utilização de óleos vegetais.

The effects of different sources of fat in the diet of layer hens on performance and egg quality were recorded in two experiments. Four treatments were defined by the lipid source added to the diets: soybean oil, sunflower oil, linseed oil and control diet (without oil added). The experiments were carried out with layers from 20 to 54 weeks of age, respectively, for eight weeks. Production parameters (feed intake, feed conversion, egg production, and egg weight) and quality of eggs (percentages of yolk, albumen, and shell; total solids of yolk; Haugh units; pH of albumen; and yolk color) were evaluated. Among the parameters of production and quality of the eggs, only the weight of eggs and percentage of yolk of young hens were affected by the inclusion of vegetable oils in the diet. These eggs were significantly heavier and had higher percentage when compared with the eggs of hens fed the control diet. It was concluded that the utilization of different sources of oils in layers diet did not change performance and egg quality , except egg weigh of young layers, that increased with the utilization of vegetables oils.

RESUMO O gorgulho do eucalipto Gonipterus scutellatus Gyllenhal foi encontrado no Estado do Espírito Santo atacando plantações clonais de Eucalyptus urophylla x E. grandis (híbrido “urograndis”). Essa espécie de gorgulho é conhecida no Brasil desde 1979, tendo sua distribuição geográfica restrita aos estados da região Sul e São Paulo. A introdução do inseto no Estado do Espírito Santo foi provavelmente acidental e sua ocorrência tem se limitado à região central do Estado. Nos levantamentos de campo não foi detectado o parasitóide de ovos Anaphes nitens (Hymenoptera: Mymaridae), que é o principal inimigo natural do gorgulho do eucalipto.

ABSTRACT The eucalyptus snout beetle Gonipterus scutellatus Gyllenhal was found in Espirito Santo State, Brazil, attacking clonal plantations of Eucalyptus urophylla x E. grandis (hybrid “urograndis”). The presence of this species in Brazil has been known since 1979, with a geographical distribution restricted to Brazil’s South and São Paulo State. The pest’s introduction to the state of Espírito Santo was probably accidental and its occurrence has been limited to the central region of the state. Field surveys did not detect the egg parasitoid Anaphes nitens (Hymenoptera: Mymaridae), which is the main natural enemy of G. scutellatus.
