Published: May 2016

Aims: Like most European countries, Norway has refrained from mandatory food fortification with folic acid to reduce the number of neural tube defects. We explored the role of folic acid and multivitamin supplements in the prevention of neural tube defects among newborn infants. Methods: We used data from the Medical Birth Registry of Norway, 1999–2013. A total of 528,220 women had 880,568 pregnancies resulting in 896,674 live- and stillborn infants, of whom 270 had neural tube defects. Relative risks were estimated with log-binomial regression. Results: From 1999 to 2013, intake of folic acid supplements increased from 4.8% to 27.4%. Vitamin supplement use was more frequent in older, married or cohabiting women and those with lower parity, as well as women who did not smoke during pregnancy. The overall adjusted relative risk of infant neural tube defects associated with maternal vitamin intake before pregnancy relative to no intake was 0.76 (95% confidence interval: 0.53–1.10). When we divided our study period in two (1999–2005 and 2006–2013), we found a significantly reduced risk of neural tube defects overall by vitamin use in the second time period, but not in the first: adjusted relative risk 0.54 (95% confidence interval: 0.31–0.91) and 1.02 (95% confidence interval: 0.63–1.65), respectively. Conclusions:Over the full study period, we found no statistically significant association between vitamin use and neural tube defects overall. However, vitamin use was associated with a significantly lower risk of neural tube defects in the second half of the study period, 2006–2013.

Objetivou-se descrever o perfil biosociodemográfico de mães de filhos a termo e prematuros, conhecer a percepção das mães com relação às diferenças de filhos a termo e prematuros em domicílio e averiguar se existem dificuldades encontradas pelas mães durante desenvolvimento dos filhos prematuros no domicílio. Pesquisa qualitativa, exploratória e descritiva, com uso da entrevista semiestruturada para coleta de dados, desenvolvida nas clínicas de fisioterapia, no município de Jequié-BA. Participaram oito mães de filhos prematuros e a termos. Para análise dos dados utilizou-se a análise de Conteúdo de Bardin. Os resultados apontaram para 03 categorias: As diferenças existentes acerca da evolução motora dos dois filhos; Empecilhos domiciliares para o desenvolvimento motor; e Evoluções do desenvolvimento motor com base no tratamento fisioterapêutico dos filhos prematuros. O estudo evidenciou que algumas mães diferenciam seus filhos com base no desenvolvimento motor e cognitivo e que a preparação da casa não é feita para a chegada de um filho prematuro.
A TALE OF TWO NARROW-LINE REGIONS: IONIZATION, KINEMATICS, AND SPECTRAL ENERGY DISTRIBUTIONS FOR A LOCAL PAIR OF MERGING OBSCURED ACTIVE GALAXIES

Published: May 2016

We explore the gas ionization and kinematics, as well as the optical-IR spectral energy distributions for UGC 11185, a nearby pair of merging galaxies hosting obscured active galactic nuclei (AGNs), also known as SDSS J181611.72+423941.6 and J181609.37+423923.0 (J1816NE and J1816SW, z ≈ 0.04). Due to the wide separation between these interacting galaxies (∼23 kpc), observations of these objects provide a rare glimpse of the concurrent growth of supermassive black holes at an early merger stage. We use BPT line diagnostics to show that the full extent of the narrow-line emission in both galaxies is photoionized by an AGN, and confirm the existence of a 10 kpc-scale ionization cone in J1816NE, while in J1816SW the AGN narrow-line region is much more compact (1–2 kpc) and relatively undisturbed. Our observations also reveal the presence of ionized gas that nearly spans the entire distance between the galaxies, which is likely in a merger-induced tidal stream. In addition, we carry out a spectral analysis of the X-ray emission using data from XMM-Newton. These galaxies represent a useful pair to explore how the [O iii] luminosity of an AGN is dependent on the size of the region used to explore the extended emission. Given the growing evidence for AGN “flickering” over short timescales, we speculate that the appearances and impacts of these AGNs may change multiple times over the course of the galaxy merger, which is especially important given that these objects are likely the progenitors of the types of systems commonly classified as “dual AGNs.”
TAXA DE POBREZA E POPULAÇÃO RURAL NO BRASIL: ANÁLISE ESPACIAL DOS PERÍODOS 2000 E 2010

Published: May 2016

O objetivo do presente artigo é analisar a distribuição espacial da pobreza rural nos municípios brasileiros e a relação entre população rural e taxa de pobreza nos anos de 2000 e 2010. O trabalho utiliza a Análise Exploratória dos Dados Espaciais para identificar o coeficiente bivariado I de Moran, o gráfico de dispersão, o mapa de significância e finalmente o mapa de cluster das variáveis dos municípios. Os dados são coletados no Instituto Brasileiro de Geografia e Estatística (IBGE) através dos censos de 2000 e 2010. Verificou-se que entre 2000 e 2010 ocorreu um aumento pouco expressivo da autocorrelação espacial positiva entre o percentual da população rural e taxa de pobreza para os municípios brasileiros. A conclusão do estudo é que, as cidades nas quais se concentram uma grande população rural continuam apresentando uma alta taxa de pobreza, confirmando a hipótese de que a população rural tem dificuldade em usufruir de políticas de combate à pobreza devido à dificuldade do acesso a essas informações e pelo distanciamento físico. Por outro lado, há indícios que o PRONAF surge como uma política que pode contribuir para minimizar os seus efeitos, mesmo que lentamente reduzir a pobreza rural.
Genetic and morphological diversity in Stachys lavandulifolia (Lamiaceae) populations

Published: May 2016

Stachys lavandulifolia Vahl. (Lamiaceae) is an important medicinal plant that grows in different parts of Iran and forms many geographical populations. We have no information on its population genetic structure, genetic diversity, and morphological variability in Iran. Therefore, we planned a genetic and morphological investigation in St. lavandulifolia geographical populations in Iran. The obtained data are important for conservation and germplasm management of this medicinal plant species. Seventy-four plants were randomly collected from 14 geographical populations and studied for genetic diversity (ISSR molecular markers) and morphological variability. The  highest value for gene diversity occurred in populations 1 and 4 (0.133 and 0.129, respectively). The  latitude and altitude were positively correlated with gene diversity and genetic polymorphism while longitude was negatively correlated with them. The Mantel test showed correlation between genetic distance and geographical distance. AMOVA revealed a significant genetic difference among populations and showed that 58% of total genetic variation was due to within-population diversity. The STRUCTURE analysis and K-Means clustering identified two gene pools for St. lavandulifolia. The  consensus tree of both molecular and morphological data identified divergent populations.
Pacific‐Atlantic Circumpolar Deep Water coupling during the last 500 ka

Published: May 2016

Investigating the interbasin deepwater exchange between the Pacific and Atlantic Oceans over glacial‐interglacial climate cycles is important for understanding circum‐Antarctic Southern Ocean circulation changes and their impact on the global Meridional Overturning Circulation. We use benthic foraminiferal δ13C records from the southern East Pacific Rise to characterize the δ13C composition of Circumpolar Deep Water in the South Pacific, prior to its transit through the Drake Passage into the South Atlantic. A comparison with published South Atlantic deepwater records from the northern Cape Basin suggests a continuous water mass exchange throughout the past 500 ka. Almost identical glacial‐interglacial δ13C variations imply a common deepwater evolution in both basins suggesting persistent Circumpolar Deep Water exchange and homogenization. By contrast, deeper abyssal waters occupying the more southern Cape Basin and the southernmost South Atlantic have lower δ13C values during most, but not all, stadial periods. We conclude that these values represent the influence of a more southern water mass, perhaps Antarctic Bottom Water (AABW). During many interglacials and some glacial periods, the gradient between Circumpolar Deep Water and the deeper southern Cape Basin bottom water disappears suggesting either no presence of AABW or indistinguishable δ13C values of both water masses.
