Sleep-time physiological recovery is associated with eating habits in distressed working-age Finns with overweight: secondary analysis of a randomise…
2021
Background Association of physiological recovery with nutrition has scarcely been studied. We investigated whether physiological recovery during sleep relates to eating habits, i.e., eating behaviour and diet quality. Methods Cross-sectional baseline analysis of psychologically distressed adults with overweight (N = 252) participating in a lifestyle intervention study in three Finnish cities. Recovery measures were based on sleep-time heart rate variability (HRV) measured for 3 consecutive nights. Measures derived from HRV were 1) RMSSD (Root Mean Square of the Successive Differences) indicating the parasympathetic activation of the autonomic nervous system and 2) Stress Balance (SB) indica…
Towards chemical communication between gated nanoparticles.
2014
The design of comparatively simple and modularly configurable artificial systems able to communicate through the exchange of chemical messengers is, to the best of our knowledge, an unexplored field. As a proof-of-concept, we present here a family of nanoparticles that have been designed to communicate with one another in a hierarchical manner. The concept involves the use of capped mesoporous silica supports in which the messenger delivered by a first type of gated nanoparticle is used to open a second type of nanoparticle, which delivers another messenger that opens a third group of gated nanoobjects.We believe that the conceptual idea that nanodevices can be designed to communicate with …
Optical chemosensors and reagents to detect explosives

[EN] This critical review is focused on examples reported from 1947 to 2010 related to the design of chromo-fluorogenic chemosensors and reagents for explosives (141 references). © 2012 The Royal Society of Chemistry.
Acetic acid compared with i-scan imaging for detecting Barrett's esophagus: a randomized, comparative trial.
2013
Background Traditional surveillance in patients with Barrett's esophagus (BE) has relied on random biopsies. Targeted biopsies that use advanced imaging modalities may significantly improve detection of specialized columnar epithelium (SCE). Objective We compared the efficacy of targeted biopsies that used i -scan or acetic acid to random biopsies in the detection of SCE. Design Patients with visible columnar lined epithelium or known BE were randomized at a 1:1 ratio to undergo acetic acid application or i -scan with targeted biopsies. Setting Targeted biopsies were performed based on surface architecture according to the Guelrud classification followed by 4-quadrant biopsies. Patients A t…
¿Se benefician de los programas de intervención que no tratan específicamente el consumo de alcohol los maltratadores con problemas de consumo abusiv…
2013
En el ámbito de la intervención con maltratadores y de la investigación en torno a la mejora de la efectividad de estas intervenciones el consumo abusivo de alcohol ha sido uno de los factores de riesgo que ha recibido especial atención. El objetivo de este trabajo es analizar la relación entre el consumo abusivo de alcohol, el proceso de cambio debido a la intervención y el abandono prematuro. Para ello se utilizó una muestra de 86 hombres consumidores de riesgo y 80 hombres no consumidores de riesgo, todos ellos condenados por violencia contra la mujer en las relaciones de pareja y participando en un programa de intervención en medio comunitario que no trata específicamente el problema de…

Análisis de la distribución del tamaño de parches de vegetación como indicador de degradación de los encinares mediterráneos
2019
[ES] La monitorización y la gestión de la Desertificación requieren de indicadores útiles y sencillos de aplicar que detecten a tiempo el momento crítico antes de que ésta sea irreversible. El presente trabajo analiza la universalidad de uno de estos indicadores, la relación entre número y tamaño de parches de vegetación, cuyo uso ha sido recomendado para monitorizar la desertificación, aplicándolo a encinares del Sistema Ibérico a lo largo de gradientes simultáneos de aridez y de uso.
Indicators and Landscape

The chapter provides criteria for the selection of environmental indicators and explores the question of landscape indicators, while also offering the potential batteries.
IANUS: Comparative analysis
2002
Jointly with the application of IANUS model in the selected facilities, in WP4 Ambiente Italia has to produce an evaluation and comparison between different facilities and core indicators. The aim of this paper is to show collected data, computed indicators and comparison facilities throuh suggested indicator evaluation system.
Screening of oxazepine indole enantiomers by means of high performance liquid chromatography with imprinted polymer stationary phase.
2004
Chromatographic enantiomer separations of different oxazepine indole derivatives were performed using a molecularly imprinted polymer. A 5aR,12R,13S-trans-6,6-dimethyl-12,13-dihydro-6H-5a, 1 3-methanoindolo[2,1-b][1,3]naphthoxazepine-12-carboxamide enantiomerderivative was used as a template and the resultant polymer has shown enantiomer recognition for series of template related compounds. The mechanistic description of the chiral discrimination process is scrutinised, comparing the discrimination between the different conformations and substituents of the oxazepine indoles.
