Análise faunística de coleópteros em sistema silvipastoril

The aim of this study was to conduct a survey of beetles (Coleoptera) in a silvicultural-pastoral system, estimating constancy, abundance, richness, diversity of families and seasonality, from July 2006 to June 2008. The study was carried out at the Embrapa Dairy Cattle station, in Coronel Pacheco, Minas Gerais, Brazil. The beetles were collected in Malaise traps, every two weeks, and taken to the laboratory for analysis. A total of 26 families, 294 morphospecies and 1,606 specimens were found. The Elateridae, Mordelidae, Chrysomelidae, Coccinellidae and Curculionidae families were the most abundant, rich and diverse. The Scarabaeidae and Scolytidae families were also among the most abundant, and the Cerambycidae family was among the richest, while the Bruchidae and Carabidae families presented high diversity.  The largest number of individuals and morphospecies sampled occurred during the period of rain. November 2007 presented the most (n = 535 specimens) captures of any month, followed by October 2006, September 2007, March and April of 2008.O objetivo deste trabalho foi realizar o levantamento da fauna coleóptera em sistema silvipastoril, com intuito de se obter a constância, abundância, riqueza e diversidade das famílias, tal como a sazonalidade de julho de 2006 a junho de 2008.

To be or not to be a tibial comb: A discussion on the (past) use of tibial armature in tribal/subtribal organization in Cholevinae (Coleoptera: Leiodidae)

Detailed studies of microstructure has recently been shown to provide phylogenetic signals at several supraspecific levels within leiodid coleopterans, as well as in other insects. The tribe Ptomaphagini (Leiodidae: Cholevinae), with a Holarctic-Neotropical-Oriental distribution, has been characterized, among other things, by having a comb of equal-sized, flat spines around the apex of the tibiae of all legs, with a row of spines extending along the outer edge of the protibiae in the subtribes Baryodirina and Ptomaphaginina (but not in Ptomaphagina). A pattern similar to the one in Ptomaphaginina also occurs in the Neotropical cholevine tribe Eucatopini, and this has been used to indicate a phylogenetic relationship between the two tribes (but recent phylogenetic studies have not supported such a close relationship). We here review and revise the presence and structure of periapical (here called an ‘apical crown’) and marginal (here called an ‘external comb’) combs of spines on tibiae in Ptomaphagini, using other cholevines (with and without apical tibial combs) for comparison. We find a phylogenetic signal in an apical crown of tibial spines not interrupted at the outer spur, which seems to be an additional synapomorphy of Ptomaphagini, differing from the pattern in Eucatopini and remaining cholevines with an apical comb of spines, in which the comb is interrupted. We highlight differences not previously noticed between the apical protibial armature of Ptomaphaginina and Eucatopini

Flutuação populacional de cigarrinhas-das-pastagens em braquiária e capim-elefante

The objective of this work was to evaluate the fluctuation of spittlebug population in Brachiaria brizantha, Brachiaria decumbens and Pennisetum purpureum. The evaluations were conducted in field conditions, between September 2005 and March 2007. Spittlebug nymphs and adults were counted on B. brizantha cultivars Marandu, Xaraés and Arapoti, subjected to alternating grazing; on B. decumbens in a silvipastoral system and on 78 genotypes of P. purpureum. The Deois schach population density was greater on the Arapoti cultivar than on the Xaraés and Marandu cultivars. On B. decumbens, the number of spittlebugs was four times greater than on B. brizantha. No significant differences were observed in the number of spittlebugs infesting the different genotypes of P. purpureum.O objetivo deste trabalho foi avaliar a flutuação populacional de cigarrinhas-das-pastagens em Brachiaria brizantha, Brachiaria decumbens e Pennisetum purpureum.

Fatores de risco para o desenvolvimento de pseudoartrose: uma revisão integrativa

Introduction: Pseudarthrosis is a complication that occurs in the process of consolidation of the fractured bone, being caused, above all, by mechanical instability, deficient vascularization and inadequate or late treatment. Therefore, the objective of this study was to discuss the risk factors that permeate this clinical scenario, in order to aim for an improvement in patient’s quality of life and prevent such situation. Methodology: This is an integrative literature review. The Health Sciences Descriptors platform (DeCS/MeSH) was used, using the descriptors “pseudoarthrosis” and “risk factors” in both Portuguese and English. Therefore, a search was carried out in the databases: Pubmed, Lilacs and Scielo. A total of 363 articles were obtained. The inclusion criteria are articles from the last 5 years that answer the research question and are in Portuguese, English or Spanish, with 14 articles being included to build this research. Results: An increase in cases of pseudarthrosis was observed when related to infections, and social determinants were relevant in the complications of cases. Comorbidities proved to be possible post-surgical complications and there was a relationship between spinal deformity in adults, pseudarthrosis and nail fracture. There were also interferences from surgical techniques and the possibility of a pseudarthrosis outcome. Conclusion: Therefore, it was possible to realize that there are several risk factors for pseudarthrosis. Faced with multifactorial causes, it is necessary to understand each patient's condition, seeking to improve quality of life, in order to mitigate factors that predispose to the development of pseudarthrosis.Introdução: A pseudoartrose é uma complicação que ocorre no processo de consolidação do osso fraturado, sendo causada, sobretudo, por instabilidade mecânica, vascularização deficiente e tratamento inadequado ou tardio. Portanto, o objetivo deste estudo foi discutir os fatores de risco que permeiam tal cenário clínico, a fim de almejar melhora na qualidade de vida dos pacientes e prevenir tal quadro. Metodologia: Trata-se de uma revisão integrativa de literatura. Foi utilizada a plataforma de Descritores em Ciências da Saúde (DeCS/MeSH), utilizando os descritores “pseudoartrose” e “fatores de risco” tanto na língua portuguesa, quanto na língua inglesa. Assim, foi feita uma pesquisa nas bases de dados: Pubmed, Lilacs e Scielo.Foram obtidos um total de 363 artigos. Os critérios de inclusão são os artigos dos últimos 5 anos que respondem à pergunta de pesquisa e são de língua portuguesa, inglesa ou espanhola, sendo incluídos 14 artigos para construir essa pesquisa. Resultados: Observou-se aumento dos casos de pseudoartrose quando relacionados a infecções, bem como os determinantes sociais mostraram-se relevantes nas complicações dos casos.  As comorbidades se mostraram como possíveis complicadores no pós-cirúrgico e houve relação entre deformidade da coluna vertebral em adultos, pseudoartrose e a fratura de haste. Verificou-se também, interferências das técnicas cirúrgicas e possibilidade de desfecho em pseudoartrose. Conclusão: Logo, foi possível perceber que existem diversos fatores de risco para a pseudoartrose. Diante de causas multifatoriais, é necessário entender o quadro de cada paciente, buscando melhora da qualidade de vida, a fim de mitigar fatores que predisponham ao desenvolvimento da pseudoartrose

Otoliths-composed gelatin/sodium alginate scaffolds for bone regeneration

Evidence that otoliths, mineral-rich limestone concrescences present in the inner ear of bone fishes, can accelerate bone formation in vivo has been previously reported. The goal of this work was the development, characterization, and evaluation of the cytocompatibility of otoliths-incorporated sodium alginate and gelatin scaffolds. Cynoscion acoupaderived otoliths were characterized by X-ray fluorescence spectrometry (FRX), particle size, free lime, and weight loss by calcination. Furthermore, otoliths were incorporated into sodium alginate (ALG/OTL-s) or gelatin (GEL/OTL-s) scaffolds, previously developed by freeze-drying. Then, the scaffolds were characterized by thermogravimetric analysis (TGA/DTG), differential scanning calorimetry (DSC), infrared spectroscopy with Fourier transform (FTIR), swelling tests, and scanning electron microscopy (SEM). Cytotoxicity assays were run against J774.G8 macrophages and MC3T3-E1 osteoblasts. Data obtained from TGA/DTG, DSC, and FTIR analyses confirmed the interaction between otoliths and the polymeric scaffolds. SEM showed the homogeneous porous 3D structure rich in otolith micro-fragments in both scaffolds. Swelling of the GEL/OTL-s (63.54±3.0%) was greater than of ALG/OTL-s (13.36±9.9%) (p0.05) and significantly higher than that treated with Triton-X (p0.05). However, by 48 h, only ALG/OTL-s showed growth similar to control (p>0.05), whereas GEL/OTL showed a significantly lower growth index (p<0.05). In conclusion, the physicochemical profiles suggest proper interaction between the otoliths and the two developed polymeric 3D scaffolds. Moreover, both materials showed cytocompatibility with J774.G8 macrophages but the growth of MC3T3-E1 osteoblasts was higher when exposed to ALG/OTL-s. These data suggest that sodium alginate/otoliths scaffolds are potential biomaterials to be used in bone regeneration applications.We would like to thank the National Council for Scientific and Technological Development (CNPq) and the Foundation for Research and Technological Innovation Support of the State of Sergipe for the financial support in this study.

Juxtaposing BTE and ATE – on the role of the European insurance industry in funding civil litigation

One of the ways in which legal services are financed, and indeed shaped, is through private insurance arrangement. Two contrasting types of legal expenses insurance contracts (LEI) seem to dominate in Europe: before the event (BTE) and after the event (ATE) legal expenses insurance. Notwithstanding institutional differences between different legal systems, BTE and ATE insurance arrangements may be instrumental if government policy is geared towards strengthening a market-oriented system of financing access to justice for individuals and business. At the same time, emphasizing the role of a private industry as a keeper of the gates to justice raises issues of accountability and transparency, not readily reconcilable with demands of competition. Moreover, multiple actors (clients, lawyers, courts, insurers) are involved, causing behavioural dynamics which are not easily predicted or influenced. Against this background, this paper looks into BTE and ATE arrangements by analysing the particularities of BTE and ATE arrangements currently available in some European jurisdictions and by painting a picture of their respective markets and legal contexts. This allows for some reflection on the performance of BTE and ATE providers as both financiers and keepers. Two issues emerge from the analysis that are worthy of some further reflection. Firstly, there is the problematic long-term sustainability of some ATE products. Secondly, the challenges faced by policymakers that would like to nudge consumers into voluntarily taking out BTE LEI

Search for stop and higgsino production using diphoton Higgs boson decays

Results are presented of a search for a "natural" supersymmetry scenario with gauge mediated symmetry breaking. It is assumed that only the supersymmetric partners of the top-quark (stop) and the Higgs boson (higgsino) are accessible. Events are examined in which there are two photons forming a Higgs boson candidate, and at least two b-quark jets. In 19.7 inverse femtobarns of proton-proton collision data at sqrt(s) = 8 TeV, recorded in the CMS experiment, no evidence of a signal is found and lower limits at the 95% confidence level are set, excluding the stop mass below 360 to 410 GeV, depending on the higgsino mass

Severe early onset preeclampsia: short and long term clinical, psychosocial and biochemical aspects

Preeclampsia is a pregnancy specific disorder commonly defined as de novo hypertension and proteinuria after 20 weeks gestational age. It occurs in approximately 3-5% of pregnancies and it is still a major cause of both foetal and maternal morbidity and mortality worldwide1. As extensive research has not yet elucidated the aetiology of preeclampsia, there are no rational preventive or therapeutic interventions available. The only rational treatment is delivery, which benefits the mother but is not in the interest of the foetus, if remote from term. Early onset preeclampsia (<32 weeks’ gestational age) occurs in less than 1% of pregnancies. It is, however often associated with maternal morbidity as the risk of progression to severe maternal disease is inversely related with gestational age at onset2. Resulting prematurity is therefore the main cause of neonatal mortality and morbidity in patients with severe preeclampsia3. Although the discussion is ongoing, perinatal survival is suggested to be increased in patients with preterm preeclampsia by expectant, non-interventional management. This temporising treatment option to lengthen pregnancy includes the use of antihypertensive medication to control hypertension, magnesium sulphate to prevent eclampsia and corticosteroids to enhance foetal lung maturity4. With optimal maternal haemodynamic status and reassuring foetal condition this results on average in an extension of 2 weeks. Prolongation of these pregnancies is a great challenge for clinicians to balance between potential maternal risks on one the eve hand and possible foetal benefits on the other. Clinical controversies regarding prolongation of preterm preeclamptic pregnancies still exist – also taking into account that preeclampsia is the leading cause of maternal mortality in the Netherlands5 - a debate which is even more pronounced in very preterm pregnancies with questionable foetal viability6-9. Do maternal risks of prolongation of these very early pregnancies outweigh the chances of neonatal survival? Counselling of women with very early onset preeclampsia not only comprises of knowledge of the outcome of those particular pregnancies, but also knowledge of outcomes of future pregnancies of these women is of major clinical importance. This thesis opens with a review of the literature on identifiable risk factors of preeclampsia
