Un applicativo Web con tecnologia single-page AJAX, servizi REST e grafica X3D, per la configurazione di modelli CAD tridimensionali

In questa tesi è stato realizzato un sistema web-based, per la configurazione di modelli meccanici tridimensionali. L’intero software è basato su architettura multi-tier. Il back-end espone servizi RESTful che permettono l’interrogazione di una base di dati contenente l’anagrafica dei modelli e l’interazione con il CAD 3D SolidWorks. Il front-end è rappresentato da due pagine HTML ideate come SPA (Single Page Application), una per l’amministratore e l’altra per l’utente finale; esse sono responsabili delle chiamate asincrone verso i servizi, dell’aggiornamento automatico dell’interfaccia e dell’interazione con immagini tridimensionali.

Desarrollo de un API RESTFUL en Symfony2 y un SDK isomorfo para dicho API en ECMAScript6

Resumen El documento que se desarrolla en los siguientes capítulos ha sido realizado como Proyecto de Fin de Grado para el Grado de Ingeniería del Software (Plan 2009) impartido por la Escuela Técnica Superior de Ingeniería de Sistemas Informáticos de la Universidad Politécnica de Madrid durante el curso académico 2014-2015 y bajo la tutela del Dr. Francisco Javier Gil Rubio, profesor del Departamento de Organización y Estructura de la Información (Actualmente DSI). La empresa Radmas Technologies pretende proporcionar con el producto Mejora Tu Ciudad —su solución para la gestión integral de Smart-Cities— un servicio REST interoperable y una capa de abstracción para el lenguaje Javascript. El presente proyecto se centra en la definición y creación de un API RESTFUL sobre la que los distintos clientes puedan interactuar con la plataforma independientemente de las herramientas de desarrollo utilizadas. Tras la definición del servicio se llevará a cabo la creación de un SDK1 válido en distintas plataformas basadas en Javascript, que facilite el acceso a aquellos clientes que utilicen dichas plataformas como punto de partida para iniciar otros desarrollos derivados. Con este pretexto nace un proyecto que pretende también cubrir todas las fases del ciclo de vida de un producto de software, ciertamente particular en este caso, ya que se trata de un ecosistema que comprende dos soluciones enfocadas hacia la interoperabilidad, una genérica y otra orientada a una única plataforma de destino, y que a su vez servirán como base para llevar a cabo futuros desarrollos. Por todo lo expuesto, el proyecto cubrirá las siguientes etapas:  Estudio de la problemática: se describe la situación en la que se encuentra la compañía y los motivos por los que se propone la creación de un API REST2 y más tarde la elaboración de un Kit de Desarrollo de Software (SDK) orientado exclusivamente a plataformas basadas en Javascript como solución a las necesidades de los potenciales clientes.  Estudio teórico de las distintas tecnologías y protocolos disponibles en los cuales se sustentarán los desarrollos que se lleven a cabo.  Estimación de tiempos, planificación y gestión de tareas mediante metodologías ágiles y desarrollo del producto.  Creación de una batería de pruebas y generación de un entorno para ejecutarlas que permita cubrir los distintos casos de uso requeridos por el usuario. También se hará uso, siempre que sea posible, de la metodología de trabajo conocida como TDD3 o Desarrollo Dirigido por las Pruebas.  Generación de documentación orientada a desarrolladores exponiendo las bondades y las técnicas de uso del ecosistema definido.  Creación de un conjunto de ejemplos que sirvan como punto de partida para llevar a cabo futuros desarrollos. Las fases anteriormente descritas se apoyan en los conocimientos recibidos en las distintas asignaturas que ofrece la titulación. Por tanto, haré frecuentes referencias a aquellas que tratan aspectos como los procesos de Ingeniería de Software (a través de un análisis y diseño coherentes de la estructura de la aplicación) y a la gestión de proyectos (haciendo especial hincapié en lo aprendido sobre metodologías ágiles), así como algunas de carácter más técnico que sin duda influirán en la generación de un código correcto y probado. Por todo ello este Trabajo de Fin de Grado pretende ser un desarrollo multidisciplinar en el que se obtenga como resultado un producto profesional, que haga uso de tecnologías y servicios de rabiosa actualidad y ejemplifique la realidad de los desarrollos de software modernos.

Sensitization Prevalence, Antibody Cross-Reactivity and Immunogenic Peptide Profile of Api g 2, the Non-Specific Lipid Transfer Protein 1 of Celery

Background: Celery (Apium graveolens) represents a relevant allergen source that can elicit severe reactions in the adult population. To investigate the sensitization prevalence and cross-reactivity of Api g 2 from celery stalks in a Mediterranean population and in a mouse model. Methodology: 786 non-randomized subjects from Italy were screened for IgE reactivity to rApi g 2, rArt v 3 (mugwort pollen LTP) and nPru p 3 (peach LTP) using an allergen microarray. Clinical data of 32 selected patients with reactivity to LTP under investigation were evaluated. Specific IgE titers and cross-inhibitions were performed in ELISA and allergen microarray. Balb/c mice were immunized with purified LTPs; IgG titers were determined in ELISA and mediator release was examined using RBL-2H3 cells. Simulated endolysosomal digestion was performed using microsomes obtained from human DCs. Results: IgE testing showed a sensitization prevalence of 25.6% to Api g 2, 18.6% to Art v 3, and 28.6% to Pru p 3 and frequent co-sensitization and correlating IgE-reactivity was observed. 10/32 patients suffering from LTP-related allergy reported symptoms upon consumption of celery stalks which mainly presented as OAS. Considerable IgE cross-reactivity was observed between Api g 2, Art v 3, and Pru p 3 with varying inhibition degrees of individual patients' sera. Simulating LTP mono-sensitization in a mouse model showed development of more congruent antibody specificities between Api g 2 and Art v 3. Notably, biologically relevant murine IgE cross-reactivity was restricted to the latter and diverse from Pru p 3 epitopes. Endolysosomal processing of LTP showed generation of similar clusters, which presumably represent T-cell peptides. Conclusions: Api g 2 represents a relevant celery stalk allergen in the LTP-sensitized population. The molecule displays common B cell epitopes and endolysosomal peptides that encompass T cell epitopes with pollen and plant-food derived LTP.

Rest energy expenditure is decreased during the acute as compared to the recovery phase of sepsis in newborns

Background: Little is known with respect to the metabolic response and the requirements of infected newborns. Moreover, the nutritional needs and particularly the energy metabolism of newborns with sepsis are controversial matter. In this investigation we aimed to evaluate the rest energy expenditure (REE) of newborns with bacterial sepsis during the acute and the recovery phases. Methods: We studied nineteen neonates (27.3 +/- 17.2 days old) with bacterial sepsis during the acute phase and recovery of their illness. REE was determined by indirect calorimetry and VO(2) and VCO(2) measured by gas chromatography. Results: REE significantly increased from 49.4 +/- 13.1 kcal/kg/day during the acute to 68.3 +/- 10.9 kcal/kg/day during recovery phase of sepsis (P < 0.01). Similarly, VO(2) (7.4 +/- 1.9 vs 10 +/- 1.5 ml/kg/min) and VCO(2) (5.1 +/- 1.7 vs 7.4 +/- 1.5 ml/kg/min) were also increased during the course of the disease (P < 0.01). Conclusion: REE was increased during recovery compared to the sepsis phase. REE of septic newborns should be calculated on individualized basis, bearing in mind their metabolic capabilities.

Comparison between constant and decreasing rest intervals: influence on maximal strength and hypertrophy

de Souza Jr, TP, Fleck, SJ, Simao, R, Dubas, JP, Pereira, B, de Brito Pacheco, EM, da Silva, AC, and de Oliveira, PR. Comparison between constant and decreasing rest intervals: influence on maximal strength and hypertrophy. J Strength Cond Res 24(7): 1843-1850, 2010-Most resistance training programs use constant rest period lengths between sets and exercises, but some programs use decreasing rest period lengths as training progresses. The aim of this study was to compare the effect on strength and hypertrophy of 8 weeks of resistance training using constant rest intervals (CIs) and decreasing rest intervals (DIs) between sets and exercises. Twenty young men recreationally trained in strength training were randomly assigned to either a CI or DI training group. During the first 2 weeks of training, 3 sets of 10-12 repetition maximum (RM) with 2-minute rest intervals between sets and exercises were performed by both groups. During the next 6 weeks of training, the CI group trained using 2 minutes between sets and exercises (4 sets of 8-10RM), and the DI group trained with DIs (2 minutes decreasing to 30 seconds) as the 6 weeks of training progressed (4 sets of 8-10RM). Total training volume of the bench press and squat were significantly lower for the DI compared to the CI group (bench press 9.4%, squat 13.9%) and weekly training volume of these same exercises was lower in the DI group from weeks 6 to 8 of training. Strength (1RM) in the bench press and squat, knee extensor and flexor isokinetic measures of peak torque, and muscle cross-sectional area (CSA) using magnetic resonance imaging were assessed pretraining and posttraining. No significant differences (p <= 0.05) were shown between the CI and DI training protocols for CSA (arm 13.8 vs. 14.5%, thigh 16.6 vs. 16.3%), 1RM (bench press 28 vs. 37%, squat 34 vs. 34%), and isokinetic peak torque. In conclusion, the results indicate that a training protocol with DI is just as effective as a CI protocol over short training periods (6 weeks) for increasing maximal strength and muscle CSA; thus, either type of program can be used over a short training period to cause strength and hypertrophy.

Manipulation of rest period length induces different causes of fatigue in vertical jumping

The aim of this study was to directly compare the causes of fatigue after a short- and a long-rest interval between consecutive stretch-shortening cycle exercises. Eleven healthy males jumped with different resting period lengths (short = 6.1 +/- 1 s, long = 8.6 +/- 0.9 s), performing countermovement jumps at 95% of their maximal jump height until they were unable to sustain the target height. After short- and long-rest, the maximal voluntary isometric contraction knee extension torque decreased (-7%; p = 0.04), comparing to values obtained before exercise protocols. No change was seen from pre- to post-exercise, for either short- or long-rest, in biceps femoris coactivation (-1%; p = 0.95), peak-to-peak amplitude (1%; p = 0.95) and duration (-8%; p = 0.92) of the compound muscle action potential of the vastus lateralis. Evoked peak twitch torque reduced after both exercise protocols (short = -26%, long = -32%; p = 0.003) indicating peripheral fatigue. However, central fatigue occurred only after short-rest evidenced by a reduction in voluntary activation of the quadriceps muscle (-14%; p = 0.013) measured using the interpolated twitch technique. In conclusion, after Stretch-shortening cycle exercise using short rest period length, the cause of fatigue was central and peripheral, while after using long rest period length, the cause of fatigue was peripheral.

Dipyridamole Stress and Rest Myocardial Perfusion by 64-Detector Row Computed Tomography in Patients With Suspected Coronary Artery Disease

Recently, stress myocardial computed tomographic perfusion (CTP) was shown to detect myocardial ischemia. Our main objective was to evaluate the feasibility of dipyridamole stress CTP and compare it to single-photon emission computed tomography (SPECT) to detect significant coronary stenosis using invasive conventional coronary angiography (CCA; stenosis >70%) as the reference method. Thirty-six patients (62 +/- 8 years old, 20 men) with previous positive results with SPECT (<2 months) as the primary inclusion criterion and suspected coronary artery disease underwent a customized multidetector-row CT protocol with myocardial perfusion evaluation at rest and during stress and coronary CT angiography (CTA). Multidetector-row computed tomography was performed in a 64-slice scanner with dipyridamole stress perfusion acquisition before a second perfusion/CT angiographic acquisition at rest. Independent blinded observers performed analysis of images from CTP, CTA, and CCA. All 36 patients completed the CT protocol with no adverse events (mean radiation dose 14.7 +/- 3.0 mSv) and with interpretable scans. CTP results were positive in 27 of 36 patients (75%). From the 9 (25%) disagreements, 6 patients had normal coronary arteries and 2 had no significant stenosis (8 false-positive results with SPECT, 22%). The remaining patient had an occluded artery with collateral flow confirmed by conventional coronary angiogram. Good agreement was demonstrated between CTP and SPECT on a per-patient analysis (kappa 0.53). In 26 patients using CCA as reference, sensitivity, specificity, and positive and negative predictive values were 88.0%, 79.3%, 66.7%, and 93.3% for CTP and 68.8, 76.1%, 66.7%, and 77.8%, for SPECT, respectively (p = NS). In conclusion, dipyridamole CT myocardial perfusion at rest and during stress is feasible and results are similar to single-photon emission CT scintigraphy. The anatomical-perfusion information provided by this combined CT protocol may allow identification of false-positive results by SPECT. (C) 2010 Elsevier Inc. All rights reserved.
