BACKGROUND: Posterior inferior cerebellar artery (PICA) aneurysms are an uncommon, heterogeneous group of aneurysms with poorer neurological outcomes compared to other intracranial aneurysms. At first, as part A, we conducted a systematic review of the literature to evaluate the safety and efficacy of treatment strategies for PICA-aneurysms. Subsequently, as part B, we performed a multicenter retrospective study to analyze the outcome in a large series of patients treated with contemporary microsurgical and endovascular techniques. METHODS: For the meta-analysis, a systematic search of Medline, EMBASE, Scopus and Web of Science was done for studies published through November 2015. We included studies that described treatment of PICA-aneurysms with ≥10 patients. Random-effects meta-analysis was used to pool the following outcomes: complete occlusion, technical success, periprocedural morbidity/mortality, stroke rates, aneurysm recurrence/rebleed, CN-palsies rates, and long-term neurological morbidity/mortality. As the second part, aiming to report the current trends and results in treatment strategies for PICA-aneurysms, records of 94 patients treated for PICA-aneurysms between 2000 and 2015 at 3 large referral neurovascular centers were retrospectively reviewed. RESULTS: In the meta-analysis, we...

Most commercial crops show photosynthetic mechanisms C3 and C4, which set different carbon isotopes C12 or C13. Through isotopic analysis can determine the origin and prevalence of type of carbon that make up the soil organic matter (SOM) in a given area. Depending on the chemical fractionation MOS can also be divided into fractions FAF, FAH and FHU, these fractions have specific characteristics depending on their origin training and ambient conditions. The objective of this study was to evaluate the influence of plant origin C3 or C4 in the formation of the chemical and molecular structure of humic substances extracted from four areas with different vegetation cover, but submitted to agroecological management. To investigate this influence were extracted humic substances (HS) of these soils, being held chemical fractionation and chemical characterization by NMR analysis, FTIR, quantification and ?13C e ?15N isotopes in the AH fraction, 13 C-CP / MAS NMR and elemental determination. From the results obtained from these analyzes it was concluded that the plant does not influence qualitative differences, but in quantitative between the chemical components of humic substances (HS), the type of photosynthetic cycle does not seem to be a determining factor in the formation and incorporation of the types of structures in HA, but rather the quantities of these structures and their humic organizational distribution. The chemometric theoretical analyzes indicate that the development and preservation of humic these soils may be possible in intensive management systems such as rotation upon application of exogenous sources of stabilized SH, as well as favoring the humidification process in less managed systems as pasture and SAF. In this study it was demonstrated by characterization and chemometrics applied to AH of an agro-ecological system, the current state of MOS in terms of stability and structural enrichment and being proposed possible avenues for recovery and preservation of SH in mineral soils that may contribute to the increase in conditions fertility and thus agricultural production. / A mat?ria org?nica do solo pode ser oriunda da decomposi??o de animais ou vegetais. A maioria das culturas comerciais apresentam mecanismos fotossint?ticos C3 ou C4, que fixam diferentes is?topos de carbono C12 ou C13. Atrav?s de an?lises isot?picas ? poss?vel determinar a origem e predomin?ncia do tipo de carbono que comp?em a mat?ria org?nica do solo (MOS) em determinada ?rea. Em fun??o do fracionamento qu?mico a MOS ainda pode ser dividida nas fra??es FAF, FAH e FHU, estas fra??es apresentam caracter?sticas especificas em fun??o da sua origem de forma??o e condi??es ambientes. O objetivo deste trabalho foi avaliar a influ?ncia da origem vegetal C3 ou C4 na forma??o da estrutura qu?mica e molecular das substancias h?micas extra?das de quatro ?reas com cobertura diferentes vegetais, por?m submetidas ao manejo agroecol?gico. Para averiguar esta influ?ncia foram extra?das as substancias h?micas (SH) destes solos, sendo realizado o fracionamento qu?mico e caracteriza??o qu?mica atrav?s de an?lises de RMN, FTIR, quantifica??o de is?topos ?13C e?15N na fra??o de AH, 13C-CP/MAS NMR e a determina??o elementar. A partir dos resultados obtidos a partir dessas an?lises foi poss?vel concluir que a origem vegetal n?o influencia em diferen?as qualitativas e sim em quantitativas entre os componentes qu?micos das substancias h?micas (SH), o tipo de ciclo fotossint?tico n?o parece ser um fator determinante na forma??o e incorpora??o dos tipos de estruturas nos AH, mas sim nas quantidades destas estruturas e na sua distribui??o organizacional h?mica. As an?lises te?ricas quimiom?tricas indicam que a incorpora??o e preserva??o de MO humificada nestes solos pode ser poss?vel em sistemas de manejo intensivo como a rota??o, mediante aplica??es de fontes ex?genas de SH estabilizada, assim como tamb?m o favorecimento dos processos de humifica??o em sistemas menos manejados como pastagem e SAF. Neste estudo foi comprovado mediante carateriza??o e quimiometria aplicadas aos AH de um sistema agroecol?gico, o estado atual da MOS em termos de estabilidade e enriquecimento estrutural e sendo propostas poss?veis vias para a recupera??o e preserva??o das SH em solos minerais que possam contribuir ao aumento das condi??es de fertilidade e consequentemente da produ??o agr?cola.

Here we assess how population dynamics of two butterfly species (Heliconius erato and Heliconius mepomene) respond to environmental and seasonal variations. A mark-release-recapture study carried out in an Atlantic forest reserve, 15 Km from Natal, Rio Grande do Norte, Brazil, for 3 years, during the dry and rainy season, with three visits weekly done. Information such as species, wing lenght, site of capture, pollen load and phenotype (number of spots) (in H. erato only) were noted for each capture. Seasonal variation exists in capture rates of the two species, with great capture rates during the rainy season. Despite finding differences in the mean density of individuals of the two species among the different collection areas, this difference was only significant between floodplain and central areas, and no influence of seasonality was observed in the mean density between the areas. Seasonality in wing size was only observed for H. erato, with larger wings during the rainy season. Females carried larger pollen loads than males both species, but species were similar. Only males differed seasonally, with larger pollen loads during the rainy season. The distribution of the number of wing spots did not vary between the dry and rainy seasons, and the number of spots in males and females was similar. Therefore, we conclude that there was a strong influence of seasonal variation in the population dynamic of the two Heliconius species, as well as in several aspects of their biology / Ambientes tropicais, assim como temperados, costumam se deparar com fortes varia??es sazonais em seus regimes clim?ticos, manifestadas atrav?s de per?odos alternados de seca e chuva, que podem ter pronunciada influ?ncia em diversos aspectos da vida dos organismos que neles habitam. O presente estudo teve como objetivo avaliar como a din?mica populacional de duas esp?cies de borboleta (Heliconius erato e Heliconius melpomene) responde ?s varia??es ambientais sazonais por elas enfrentadas. Um trabalho de marca??o e recaptura das esp?cies foi realizado em uma reserva de mata Atl?ntica localizada cerca de 15 km da cidade de Natal (RN), durante um per?odo de tr?s anos, nos meses mais secos e chuvosos do ano, com tr?s visitas semanais. Informa??es como esp?cie, comprimento alar, local de captura, idade, tamanho da carga pol?nica coletada e fen?tipo (n?mero de manchas na por??o ventral das asas anteriores) em H. erato foram obtidas para cada captura. Observou-se varia??o sazonal nas taxas de captura das duas esp?cies, com maior incid?ncia nos per?odos mais chuvosos, e baixa taxa de recaptura, principalmente nos per?odos mais secos. Apesar de encontrada diferen?a na densidade m?dia de indiv?duos das duas esp?cies entre as diferentes ?reas de coleta, esta foi significativa somente entre as ?reas de v?rzea e central, e n?o foi observada influ?ncia da sazonalidade na densidade m?dia entre as ?reas. O efeito da sazonalidade sobre o comprimento alar somente foi observado para H. erato, com indiv?duos coletados nos per?odos de chuva apresentando tamanhos superiores. F?meas coletaram maiores cargas pol?nicas do que machos nas duas esp?cies, mas n?o houve diferen?a quando comparadas as esp?cies entre si. Quando analisada a influ?ncia sazonal na obten??o de p?len, somente os machos apresentaram diverg?ncias entre as esta??es, com indiv?duos capturados nos per?odos mais chuvosos coletando maiores cargas pol?nicas. Quanto ? varia??o fenot?pica em H. erato, a distribui??o do n?mero de manchas n?o variou entre as esta??es seca e chuvosa, assim como n?o houve diferen?a no n?mero de manchas entre machos e f?meas. Podemos ent?o concluir que houve forte influ?ncia da varia??o sazonal na din?mica populacional das duas esp?cies de Heliconius, bem como em v?rios aspectos de sua biologia

Gobiidae family is the most specious in the marine environment. Among its representatives, many species are part of a cryptic fauna little noticed and studied, a wide distribution with behavioral and reproductive characteristics, that make them conducive to the action of biogeographical barriers. Morphologically this family presents reduced body structures through simplification and regressions. Despite their importance in evolutionary inferences, cytogenetics data are incipient facing their species diversity, especially with western Atlantic species. In order to estimate the evolutionary diversity in Gobiidae, it were developed cytogenetic analysis and the standards body, through geometric morphometrics in five species on the Brazilian coast, Coryphopterus glaucofraenum, Bathygobius mystacium, B. soporator, Ctenogobius smaragdus e C. Boleosoma. The data show significant karyotype and morphological diversity among the species. The pericentric inversions and mergers play an important role in chromosomal evolution of this family, causing karyotypic structural and numerical differences in all species. Karyotypic and morphological comparisons among geographic samples of B. soporator from the coast of Maranh?o, Rio Grande do Norte and Bahia showed cytogenetics patterns commons, but different morphological patterns. A sample from the Atol das Rocas revealed conspicuous morphological and karyotypic differentiation of another continental populations, confirming the presence of a new island species. The approaches done reveal diversification consistent with characteristics of a group of low vagile and largely able to environmental selection due from peculiar ecological requirements / Os peixes da ordem Perciformes caracterizam-se como um modelo importante para o entendimento da estrutura gen?tica de popula??es marinhas, pois apresentam tanto exemplos de conserva??o cromoss?mica como de diversifica??o cariot?pica para alguns grupos.

Entre seus representantes, muitas esp?cies fazem parte de uma fauna cr?ptica pouco percebida e estudada, apresentando ampla distribui??o com caracter?sticas comportamentais e reprodutivas que as tornam prop?cias ? a??o de barreiras biogeogr?ficas. Morfologicamente esta fam?lia apresenta estruturas corporais reduzidas atrav?s de simplifica??es e regress?es. Dados citogen?ticos, apesar da import?ncia em infer?ncias evolutivas, s?o incipientes frente sua diversidade de esp?cies, sobretudo para esp?cies do Atl?ntico Ocidental. Visando estimar a diversidade evolutiva em Gobiidae foram desenvolvidas an?lises citogen?ticas e dos padr?es corporais, atrav?s de morfometria geom?trica, em cinco esp?cies presentes no litoral brasileiro, Coryphopterus glaucofraenum, Bathygobius mystacium, B. soporator, Ctenogobius smaragdus e C. Boleosoma. Os dados obtidos demonstram marcante diversidade cariot?pica e morfol?gica entre as esp?cies. As invers?es peric?ntricas e fus?es desempenham papel importante na evolu??o cromoss?mica desta fam?lia, ocasionando diferen?as cariot?picas estruturais e num?ricas em todas as esp?cies. Compara??es cariot?picas e morfol?gicas entre amostras geogr?ficas de B. soporator provenientes do litoral do Maranh?o, Rio Grande do Norte e Bahia evidenciaram padr?es citogen?ticos comuns, mas padr?es morfol?gicos diferentes. Uma amostra proveniente do Atol das Rocas revelou consp?cua diferencia??o cariot?pica e morfol?gica das demais popula??es continentais, confirmando a presen?a de uma nova esp?cie insular. As abordagens empregadas revelam diversifica??es compat?veis com um grupo com caracter?sticas de baixa vagilidade e amplamente sujeito a sele??o ambiental decorrente de exig?ncias ecol?gicas peculiares

For this reason, many scientific researches is currently focused on the study of materials at ever smaller scales, in order to understand and better control the properties of nanoscale systems, i.e. with dimensions of the order of nanometers, such as thin film ferromagnetic. In this work, we analyze the structural and magnetic properties and magnetoresistance effect in Permalloy-ferromagnetic thin films produced by magnetron sputtering. In this case, since the magnetoresistance effect dependent interfaces of thin films, this work is devoted to the study of the magnetoresistance in samples of Permalloy in nominal settings of: Ta[4nm]/Py[16nm]/Ta[4nm], Ta[4nm]/Py[16nm]/O2/Ta[4nm], Ta[4nm]/O2/Py[16nm]/Ta[4nm], Ta[4nm]/O2/Py[16n m]/O2/Ta[4nm], as made and subjected to heat treatment at temperatures of 160?C, 360?C e 460?C, in order to verify the influence of the insertion of the oxygen in the layer structure of samples and thermal treatments carried out after production of the samples.

Para compreender o comportamento desses sistemas, v?rios modelos na ?rea de Redes Complexas foram propostos. Barab?si e Albert propuseram um modelo que inclu?a dois mecanismos b?sicos (crescimento e liga??o preferencial), reproduzindo um comportamento caracter?stico de alguns sistemas reais: a distribui??o de conectividade em lei de pot?ncia.

This occupation contributes to the destruction of both the ecological and environmental structure of the city. One of the strategies to minimize these effects is to consider the legislation, concerning the urban land use and the preservation / conservation of vegetation, as well as the preparation of the Environmental Zoning. The main objective was, to propose an Environmental Zoning based on the analysis of urban sprawl and its impact on the environment, the distribution of vegetation over a period of 17 years (1997-2014) and the legislation to contribute with elements that inform and enable the development of urban and environmental planning in the municipality of Matola. Three satellite images from TM / Landsat 5 and OLI / Landsat 8 orbital sensor, SRTM data, population data and digital database of the city/country were utilized as input data. It was employed visual interpretation, images segmentations digital classification and geoprocessing technics. Results, indicated that urban area increased about 180.964m2, corresponding to 254.91% between 1997 and 2014. The area of vegetation cover reduced to 118.74m2 (52.62%) in 17 years. The Vegetation Cover Index (VCI) for total mapped area, reduced from, 61.25% in 1997, to 39.65% in 2007 and 29.02% in 2014. However, the detailed study of the VCI to different neighborhoods of Matola, showed a very uneven spatial distribution. The Environmental Zoning proposed, was made by integrating several information?s plans (thematic maps) and features five zones, namely: (i) Total Conservation Zone; (ii) Sustainable Use Conservation Zone; (iii) Expansion Urban Zone; (iv) Environmental Control Zone and (v) Recovery Zone. Has also proposed the creation of three protected areas located in the Total Conservation Zone: (i) Integral Natural Reserve, (ii) Natural Monument and (iii) Permanent Protection Green Area. This research will be important to municipal management and will serve as a basis for preparing the next general and partial urbanization plans and Matola Master Plan 2019/2020, achieving the objectives of the Environmental Strategy for Sustainable Development of Mozambique (2007 - 2017) and the objectives of Agenda 2030 of the UN. / A expans?o da macha urbana no Munic?pio da Matola em Mo?ambique tem sido significante nas ?ltimas d?cadas e ? feita de forma n?o estruturada. Esta forma de ocupa??o do espa?o contribui para a destrui??o da sua estrutura ecol?gica e ambiental. Uma das estrat?gias para minimizar esses efeitos ? levar em considera??o a legisla??o, concernente ? ocupa??o do solo urbano e ? preserva??o/conserva??o da cobertura vegetal, assim como a elabora??o do Zoneamento Ambiental. A pesquisa tem como objetivo elaborar uma proposta de Zoneamento Ambiental a partir da an?lise da expans?o urbana, da distribui??o da cobertura vegetal em um per?odo de 17 anos (1997 - 2014) e da legisla??o, de forma a contribuir com elementos que informem ou possibilitem a elabora??o dos planejamentos urbano e ambiental do Munic?pio da Matola. Foram usadas tr?s imagens dos sensores orbitais TM/Landsat 5 e OLI/Landsat 8, dados SRTM, dados populacionais e a base de dados cartogr?fica digital do Munic?pio/Pa?s. Empregaram-se t?cnicas de interpreta??o visual, de segmenta??o, de classifica??o de imagens e de geoprocessamento. Dos resultados, a ?rea urbana aumentou cerca de 180,964m2, o que corresponde a 254,91% em rela??o ao ano de 1997. A ?rea da cobertura vegetal reduziu 118,74m2 (52,62%) em 17 anos. Verificou-se redu??o do ?ndice de Cobertura Vegetal (ICV) da totalidade na ?rea mapeada ao longo do tempo, sendo 61,25% em 1997, 39,65% em 2007 e 29,02% em 2014. No entanto, o estudo detalhado do ICV tendo como recorte espacial os bairros, mostrou distribui??o espacial bastante desigual. O Zoneamento Ambiental proposto, foi elaborado a partir da integra??o de diferentes planos de informa??o (mapas tem?ticos) e apresenta cinco zonas: (i) Zona de Conserva??o Total; (ii) Zona de Conserva??o de Uso Sustent?vel; (iii) Zona de Expans?o Urbana; (iv) Zona de Controle Ambiental e (v) Zona de Recupera??o. Foi tamb?m proposto a cria??o de tr?s Unidades de Conserva??o localizadas na Zona de Conserva??o Total: (i) Reserva Natural Integral, (ii) Monumento Natural e (iii) ?rea Verde de Prote??o Permanente. O trabalho ser? de grande valia para a gest?o municipal e servir? de base para, a elabora??o dos pr?ximos planos gerais e parciais de urbaniza??o e o Plano de Estrutura Urbana da Cidade da Matola de 2019/2020, alcan?ar os objetivos da Estrat?gia Ambiental para o Desenvolvimento Sustent?vel de Mo?ambique (2007 - 2017) e os objetivos da Agenda 2030 da ONU.

Objective: Little epidemiological evidence exists on rumination disorder behavior (RB) and pica behavior (PB). We examined prevalence of RB and PB and presence of comorbid feeding/eating disorder symptoms among school-aged children. Methods: In elementary schools in Switzerland, 1,430 children (54.0% female) ages seven to 13 completed Eating Disorder Examination-Questionnaire for children (ChEDE-Q) and Eating Disturbances in Youth Questionnaire (EDY-Q). Results: EDY-Q data behavior frequency showed 9.7% reported RB only, 10.0% reported PB only, and 3.1% reported RB+PB (≥1 on 0-6 Likert scale). At a clinical cut-off score of ≥4 (at least “often true”), 1.7% had RB only, 3.8% had PB only, and 1.1% had RB+PB. Avoidant/restrictive food intake disorder symptoms were most common in those with RB+PB, and more common in those with RB or PB than those without. Degree of eating disorder symptoms (by ChEDE-Q) over the past 28 days were similar among those with RB, PB, or RB+PB, but less common in those without RB or PB. Discussion: RB and PB were commonly reported in our sample of school-aged children, even at a potential clinically significant cut-off. Our findings also suggest that degree of eating disorder symptom comorbidity is similar between those with RB and PB.

Methods: In elementary schools in Switzerland, 1,430 children (54.0% female) ages seven to 13 completed Eating Disorder Examination-Questionnaire for children (ChEDE-Q) and Eating Disturbances in Youth Questionnaire (EDY-Q). Results: EDY-Q data behavior frequency showed 9.7% reported RB only, 10.0% reported PB only, and 3.1% reported RB+PB (≥1 on 0-6 Likert scale). At a clinical cut-off score of ≥4 (at least “often true”), 1.7% had RB only, 3.8% had PB only, and 1.1% had RB+PB. Avoidant/restrictive food intake disorder symptoms were most common in those with RB+PB, and more common in those with RB or PB than those without. Degree of eating disorder symptoms (by ChEDE-Q) over the past 28 days were similar among those with RB, PB, or RB+PB, but less common in those without RB or PB. Discussion: RB and PB were commonly reported in our sample of school-aged children, even at a potential clinically significant cut-off. Our findings also suggest that degree of eating disorder symptom comorbidity is similar between those with RB and PB.
