Association between osteocalcin and cognitive performance in healthy older adults.
2016
INTRODUCTION: cognitive deterioration and reductions of bone health coincide with increasing age. We examine the relationship between bone composition and plasma markers of bone remodelling with measures of cognitive performance in healthy adults.METHODS: this cross-sectional study included 225 old (52% women, mean age: 74.4 ± 3.3 years) and 134 young (52% women, mean age: 23.4 ± 2.7 years) adult participants from the MyoAge project. Whole body bone mineral density was measured by dual-energy X-ray absorptiometry. Blood analyses included a panel of bone-related peptides (dickkopf-1, osteoprotegerin, osteocalcin (OC), osteopontin, sclerostin, parathyroid hormone and fibroblast growth factor …
La conformità dei prodotti agli standard tecnici tra tutela del consumatore e limiti alla responsabilità del fabbricante
2022
La crescente rilevanza assunta dalla normazione tecnica nell’ambito della disciplina della sicurezza dei prodotti si riflette su plurimi profili che investono sia la responsabilità del fabbricante per i danni cagionati da un prodotto non conforme, e quindi difettoso, sia la più complessa questione concernente la responsabilità per i danni derivanti dall’utilizzo di un prodotto conforme agli standard legislativi, ma nondimeno pericoloso. Proprio nell’ambito di questa peculiare questione si riscontra un rinnovato interesse per il severo regime di responsabilità contemplato dall’art. 2050 c.c. che da una parte fornisce una maggiore tutela al consumatore, ma, dall’altra, costituisce un ostacolo…

Study que Stion What are the long term trends in the total (live births, fetal deaths, and terminations of pregnancy for fetal anomaly) and live birth prevalence of neural tube defects (NTD) in Europe, where many countries have issued recommendations for folic acid supplementation but a policy for mandatory folic acid fortification of food does not exist? Method S This was a population based, observational study using data on 11 353 cases of NTD not associated with chromosomal anomalies, including 4162 cases of anencephaly and 5776 cases of spina bifida from 28 EUROCAT (European Surveillance of Congenital Anomalies) registries covering approximately 12.5 million births in 19 countries betwe…

Enhancing the luminescence efficiency of silicon-nanocrystals by interaction with H+ions
2018
The emission of silicon nanocrystals (Si-NCs), synthesized by pulsed laser ablation in water, was investigated on varying the pH of the solution. These samples emit μs decaying orange photoluminescence (PL) associated with radiative recombination of quantum-confined excitons. Time-resolved spectra reveal that both the PL intensity and the lifetime increase by a factor of ∼20 when the pH decreases from 10 to 1 thus indicating that the emission quantum efficiency increases by inhibiting nonradiative decay rates. Infrared (IR) absorption and electron paramagnetic resonance (EPR) experiments allow addressing the origin of defects on which the excitons nonradiatively recombine. The linear correl…

La responsabilidad transfronteriza por productos defectuosos en la Unión Europea
2015
Liability for defective products meets a modern legal framework applicable to cases which have an international nature in the European Union. However, the new regulatory developments have not solved the existing coordination problems and offer an unjustified complexity, so there is a certain risk that the objectives pursued by the European legislator in this strategic sector for the EU internal market are not going to be fulfilled. The objective of this study is to analyze the solutions contained in Regulation (EC) 442001, relating to jurisdiction, the recognition and enforcement of judgments in civil and commercial matters and Regulation (EC) 8642007, concerning the law applicable to non-c…

Resumen En este articulo se expone el proceso de evaluacion e intervencion realizado en un caso clinico de dispraxia verbal asociada a trastorno por deficit de atencion con hiperactividad (TDAH), subtipo combinado. En el TDAH se producen deficit en el control inhibitorio comportamental que inciden en el control, la fluencia y la sintaxis de la ejecucion de secuencias motoras complejas, como las de la articulacion del habla. Durante el desarrollo del lenguaje es probable que las caracteristicas del TDAH no favorezcan el control propioceptivo articulatorio y, en ocasiones, contribuyen a perfilar un cuadro sintomatologico de dispraxia verbal. La dispraxia verbal comporta una dificultad para cr…
Tailoring oxide properties: An impact on adsorption characteristics of molecules and metals
2014
Abstract Both density functional theory calculations and numerous experimental studies demonstrate a variety of unique features in metal supported oxide films and transition metal doped simple oxides, which are markedly different from their unmodified counterparts. This review highlights, from the computational perspective, recent literature on the properties of the above mentioned surfaces and how they adsorb and activate different species, support metal aggregates, and even catalyse reactions. The adsorption of Au atoms and clusters on metal-supported MgO films are reviewed together with the cluster׳s theoretically predicted ability to activate and dissociate O 2 at the Au–MgO(100)/Ag(100…
Mortalidad por defectos del tubo neural en México, 1980-1997
2003
Objetivo. Describir la mortalidad en México por defectos del tubo neural, durante el periodo 1980-1997. Material y métodos. Las tasas anuales de mortalidad estatales y nacionales, por defectos del tubo neural, se calcularon por 10 000 nacidos vivos. La tendencia temporal fue evaluada por el porcentaje de cambio anual obtenido mediante un modelo de regresión de Poisson. Se calculó la razón de mortalidad, tomando la media nacional como referencia. Las tasas y las razones se representaron gráficamente en mapas. Resultados. Durante el periodo la tasa bruta de mortalidad por defectos del tubo neural fue de 5.8 por 10 000 nacidos vivos. La anencefalia fue el tipo de defecto más frecuente (37.7%),…
