Nutritional Quality of the Mid-Afternoon Snack of Schooled Children between the Ages of 3 and 12 Years in Three Areas in Spain.

Background: The aim of this study was to analyze the nutritional quality of mid-afternoon snacks for schooled children aged 3 to 12 years in three areas of Catalonia (Spain).

Methods: A descriptive observational study collected information on habits and the mid-afternoon snack of 782 schooled children aged 3 to 12 years in three cities, Barcelona, Girona, and Lleida, located in Catalonia (Spain). The children's families voluntarily agreed to complete an online questionnaire that collected information about demographic data and snacking habits in the afternoon, as well as a record of mid-afternoon snack intake over three school days.

Shape Modulation of Plasmonic Nanostructures by Unconventional Lithographic Technique.

Conventional nano-sphere lithography techniques have been extended to the fabrication of highly periodic arrays of sub-wavelength nanoholes in a thin metal film. By combining the dry etching processes of self-assembled monolayers of polystyrene colloids with metal physical deposition, the complete transition from increasing size triangular nanoprism to hexagonally distributed nanoholes array onto thin metal film has been gradually explored. The investigated nano-structured materials exhibit interesting plasmonic properties which can be precisely modulated in a desired optical spectral region.

Self-Assembled Metal Nanohole Arrays with Tunable Plasmonic Properties for SERS Single-Molecule Detection.

Arrays of metal nano-holes have proved to be among of the most promising structures for applications in the field of nano-photonics and optoelectronics. Supporting both localized and propagating surface plasmons resonances, they are characterized by very high versatility thanks to the tunability of these modes, by means of the change of their periodicity, the size of the holes and metal composition. The interaction between different optical features can be exploited to modulate electromagnetic field distribution leading various hot-spots excitations on the metal surfaces.

Background & Objectives: Food-based dietary guidelines (FBDGs) have been developed to promote healthy diets and prevent chronic diseases. However, the methodological quality of Spanish FBDGs has not been systematically assessed yet. The objective of this review is to identify and assess the methodological quality of Spanish FBDGs, as well as to describe their food guides and key recommendations.

Short-range ordered 2D nanoholes: lattice-model and novel insight into the impact of coordination geometry and packing on their propagating-mode transmittance features.

Optically thin perforated gold films, fabricated using template colloidal masks self-assembled by following an elsewhere described simplified colloidal lithography protocol, are presented and discussed with the aim to develop a theory of short-range ordered nanoholes without straightforwardly extending concepts strictly related to periodic nanoholes. By Scanning Electron Microscopy (SEM) analysis of the evolution of nanohole short-range ordering and spatial coordination geometry under increasing interhole average spacing ( ), unprecedented differences in the spectroscopic response are pointed out with respect to periodic systems. First, the dependence of the wavelength of a propagating plasmon mode on is demonstrated to deviate from the linear relationship predicted by the grating-coupling picture developed for periodic arrays.

Gold nanoholes fabricated by colloidal lithography: novel insights into nanofabrication, short-range correlation and optical properties.

Colloidal lithography is widely used as a low cost and large-area deposition approach, alternative to the conventional small-area expensive lithographic techniques, for the fabrication of short-range ordered sub-wavelength metallic nanostructures. This paper contributes to the understanding of the impact of the fabrication protocol of a colloidal mask on the optical and sensing properties of short range-ordered nanohole (NH) distributions fabricated by colloidal lithography in optically thin (20 nm thick) gold films. We consider polystyrene nanospheres (PS-NSPs) with a nominal diameter of 80 nm, electrostatically adsorbed from a salt-free colloidal solution onto a polydiallyldimethylammonium (PDDA) countercharged monolayer.

Magneto-Optical properties of noble-metal nanostructures: functional nanomaterials for bio sensing.

Metallic nanostructures supporting Localized Surface Plasmon Resonances (LSPR) are characterized by their unique ability to control and manipulate light at the nanoscale. Noble metal nanostructures, such as gold nanostructures, are demonstrating to exhibit magneto-optic activity in the presence of modulated magnetic field of low intensity in transversal configuration (T-MOKE). Validation of experimental findings was achieved by numerical simulations based on Finite Element Method (FEM) techniques.

Interaction-tailored organization of large-area colloidal assemblies.

Colloidal lithography is an innovative fabrication technique employing spherical, nanoscale crystals as a lithographic mask for the low cost realization of nanoscale patterning. The features of the resulting nanostructures are related to the particle size, deposition conditions and interactions involved. In this work, we studied the absorption of polystyrene spheres onto a substrate and discuss the effect of particle-substrate and particle-particle interactions on their organization.

Posturography and dynamic pedobarography in lame dogs with elbow dysplasia and cranial cruciate ligament rupture.

Background: The usefulness of studying posture and its modifications due to locomotor deficiencies of multiple origins has been widely proven in humans. To assess its suitability in the canine species, static posturography and dynamic pedobarography were performed on lame dogs affected with unilateral elbow dysplasia and cranial cruciate ligament rupture by using a pressure platform. With this objective, statokinesiograms and stabilograms, the percentage of pressure distribution between limbs, paw area, mean pressure, and peak pressure, were obtained from lame and sound dogs.

Effect of leukocyte-reduced platelet-rich plasma on osteoarthritis caused by cranial cruciate ligament rupture: A canine gait analysis model.

The goal of this study was to objectively assess the effect of a platelet-rich plasma (PRP) derivate in English bulldogs with stifle degenerative joint disease secondary to cranial cruciate ligament rupture (CCLR). We used a force platform and affixed electrogoniometers to measure peak vertical force (PVF), vertical impulse (VI), stance time (ST), and angular range of motion (AROM), from 12 lame client-owned English bulldogs with post-CCLR stifle joint abnormalities. The 12 affected subjects were treated with 4 intra-articular injections of PRP, at 30-day intervals.

Static Posturography: A New Perspective in the Assessment of Lameness in a Canine Model.

The aim of this study was to assess the static posturography in dogs as a useful tool for diagnosis of lameness by means of the use of a pressure platform. For this purpose, a series of different parameters (pressure distribution, area of support, mean pressure, maximum pressure and statokinesiograms) were obtained from five lame dogs with unilateral elbow osteoarthritis treated with plasma rich in growth factors. Data were obtained before and 3 months after treatment, and results were compared with a control group of sound dogs of similar conformation.

Enhanced antibody recognition with a magneto-optic surface plasmon resonance (MO-SPR) sensor.

A comparison between sensing performance of traditional SPR (Surface Plasmon Resonance) and magneto-optic SPR (MOSPR) transducing techniques is presented in this work. MOSPR comes from an evolution of traditional SPR platform aiming at modulating Surface Plasmon wave by the application of an external magnetic field in transverse configuration. Previous work demonstrated that, when the Plasmon resonance is excited in these structures, the external magnetic field induces a modification of the coupling of the incident light with the Surface Plasmon Polaritons (SPP).

[Scientific evidence about the role of yogurt and other fermented milks in the healthy diet for the Spanish population].

Milk products contain proteins of high biologic value and digestibility; they also contain fat, carbohydrates, vitamins and minerals, specially calcium and phosphorus. Diversification of milk products consumption allows a high consumptiom of the above mentioned products, optimizing nutrient intake. In Spain, food consumption of milk products lower than the recommended amounts was observed in 20 to 40 % of the children and 30 to 45 % of the adults.

The Lombardy Rare Donor Programme.

Background: In 2005, the government of Lombardy, an Italian region with an ethnically varied population of approximately 9.8 million inhabitants including 250,000 blood donors, founded the Lombardy Rare Donor Programme, a regional network of 15 blood transfusion departments coordinated by the Immunohaematology Reference Laboratory of the Ca' Granda Ospedale Maggiore Policlinico in Milan. During 2005 to 2012, Lombardy funded LORD-P with 14.

Comparison of traditional methods and mitogen-stimulated direct antiglobulin test for detection of anti-red blood cell autoimmunity.

The diagnosis of autoimmune hemolytic anemia (AIHA) is based on a positive direct antiglobulin test (DAT), which is performed using various methods with different sensitivities. Recently, mitogen-stimulated (MS)-DAT was suggested to be able to identify latent anti-erythrocyte autoimmunity. Traditional methods (tube, microcolumn, and solid phase) and MS-DAT were compared in 54 consecutive cases of suspected AIHA, 28 idiopathic AIHA in clinical remission, and 12 difficult-to-diagnose cases of DAT-negative AIHA, and the results (all cases) were correlated with hematologic and hemolytic parameters.

Strategies for the transfusion of subjects with complex red cell immunisation: the Bank of rare blood donors of the Region of Lombardy.

Introduction: Selecting units of rare blood for transfusion to patients with complex immunisation is one of the most critical processes of a Transfusion Centre. In January 2005 the 'Rare Blood Components Bank - Reference Centre of the Region of Lombardy' w as established with the following goals: 1) identifying regional rare blood donors; 2) creating a regional registry of rare donors; 3) organising a regional bank of liquid and frozen rare blood units; 4) setting up a regional Immunohaematology Reference Laboratory (IRL) to type donors and resolve complex cases.

Methods: The key elements in establishing the Bank were periodic meetings organised by the directors and representatives of the regional Departments of Transfusion Medicine and Haematology (DTMH) and the institution of three working groups (informatics, regulations, finance).
