Dietary Patterns and Their Association with Body Composition and Cardiometabolic Markers in Children and Adolescents: Genobox Cohort
Diet is a key factor for obesity development; however, limited data are available on
dietary cluster analysis in children with obesity. We aimed to assess the associations between dietary
patterns and obesity and several cardiometabolic markers. Anthropometry, bioelectrical impedance,
blood pressure and plasma biomarkers of oxidative stress, inflammation and endothelial damage
were determined in 674 Caucasian children, aged 5–16, with normal or excess weight. Using a food
frequency questionnaire and cluster analysis, two consistent dietary patterns were shown, labeled as
health conscious (HC) and sweet and processed (SP). The HC pattern included a greater proportion of
participants with overweight/obesity than the SP cluster (80.1% vs. 63.8%). However, children with
obesity within the HC cluster, showed less abdominal fat, through waist to hip (0.93 vs. 0.94) and
waist to height (0.61 vs. 0.63) indexes (p < 0.01). Univariate general models showed several additional
di erences in cardiometabolic risk biomarkers in the global and stratified analyses, with a healthier
profile being observed mainly in the HC cluster. However, multivariate models questioned these
findings and pointed out the need for further studies in this field. Anyhow, our findings support the
benefits of a healthy diet and highlight the importance of dietary patterns in the cardiometabolic risk
assessment of children with overweight/obesity, beyond weight control.Plan Nacional de Investigacion Cientifica, Desarrollo e Innovacion Tecnologica (I+D+I), Instituto de Salud Carlos III-Health Research Funding (FONDOS FEDER)

Evaluación de algunos aspectos de la biocompatibilidad de biomateriales in vitro
Los biomateriales para uso médico se han ido desarrollando de acuerdo a los avances en los
campos de la medicina, bioquímica, farmacia y las ciencias de los materiales. Estos deben ser
biocompatibles, por eso es necesario desarrollar un grupo de ensayos biológicos encaminados a
este fin.
Las pruebas de citotoxicidad in vitro tienen aplicabilidad general y uso extensamente difundido
en la evaluación de un amplio rango de materiales. Se ha encontrado cierta relación entre la
citotoxicidad no específica del biomaterial in vitro y su efecto irritante in vivo.
En nuestro laboratorio se aplicó el método descrito por Stanley HR (1985) para la evaluación
toxicológica de biomateriales, habiéndose evaluado hasta la fecha diferentes materiales obtenidos
en el Centro de Biomateriales de la Universidad de La Habana, entre ellos: el obturante dental
Obtudent Fotocurado (FC), el sellante dental Cubridem Autocurado (AC), el adhesivo tisular
Tisuacryl y los cementos óseos Biograft-G y Apafill-G.
El Obtudent FC resultó citotóxico, sin embargo su citotoxicidad se encontró en el rango de la de
sus análogos comerciales. La citotoxicidad del Cubridem AC y del Tisuacryl no se diferenció
significativamente de los niveles encontrados para sus controles comerciales, al igual que el
Biograft-G, aunque en este caso el resultado fue ligeramente citotóxico según la clasificación de
Stanley. El Apafill-G no resultó citotóxico.Peer Reviewe
Transmission electron microscopy study of vertical quantum dots molecules grown by droplet epitaxy
3 páginas, 3 figuras.-- Progress in Applied Surface, Interface and Thin Film Science - SURFINT SREN II.-- PACS codes: 68.37.Lp; 81.05.Ea; 81.15.HiThe compositional distribution of InAs quantum dots grown by molecular beam epitaxy on GaAs capped InAs quantum dots has been studied in this work. Upper quantum dots are nucleated preferentially on top of the quantum dots underneath, which have been nucleated by droplet epitaxy. The growth process of these nanostructures, which are usually called as quantum dots molecules, has been explained. In order to understand this growth process, the analysis of the strain has been carried out from a 3D model of the nanostructure built from transmission electron microscopy images sensitive to the composition.This work was supported by the Spanish MCI (TEC2008-06756-C03-02/TEC), CONSOLIDER CSD2009-00013, and the Junta de Andalucia (PAI research groups TEP-120 and TIC-145, project

The Role of a Double Molecular Anchor on the Mobility and Self-Assembly of Thiols on Au(111): The Case of Mercaptobenzoic Acid
The dynamics of the self-assembly process of thiol molecules on Au(111) is affected by the interplay between molecule–substrate and molecule–molecule interactions. Therefore, it is interesting to explore the effect of a second anchor to the gold surface, in addition to the S atom, on both the order and the feasibility of phase transitions in self-assembled monolayers. To assess the role of an additional O anchor, we have compared the adsorption of two mercaptobenzoic acid isomers, 2-mercaptobenzoic acid (2-MBA) and 4-mercaptobenzoic acid (4-MBA), on Au(111). Results from scanning tunneling microscopy, X-ray photoelectron spectroscopy, electrochemical techniques, and density functional theory calculations show that the additional O anchor in 2-MBA hinders surface mobility, reducing domain size and impeding the molecular reorganization involved in phase transition to denser phases on the Au(111) substrates. This knowledge can help to predict the range order and molecular density of the thiol SAM depending on the chemical structure of the adsorbate.Instituto de Investigaciones Fisicoquímicas Teóricas y Aplicada
Numerical models of planetary nebulae with different episodes of mass ejection: the particular case of HuBi 1
We have studied the evolution of HuBi 1-like planetary nebulae, considering
several stages of mass injection. We have carried out numerical ionization+1D
hydrodynamics+atomic/ionic rate models with our code Coral 1D to reproduce
planetary nebulae that present multiple shells produced by different ejection
events around the ionizing source. Furthermore, we are interested in comparing
numerical simulations with H and [NII]6584 emission structures
and the position-velocity diagrams observed in HuBi 1. This object also has a
phase where it has drastically decreased the injection of ionized photons
ejected from the source. The result of these different stages of ejection is a
nebula with intense [NII] line emission in the inner part of the planetary
nebula and an extended HII recombination line emission around the central zone.
The model for HuBi 1 shows the capability of our code to explain the
hydrodynamical and photoionization evolution in ionization nebulae. This is our
first step with a 1D code to study these two physical phenomena at the same
time.Comment: accepte
