R&D&i Management System in Distributed Manufacturing Systems

The R&D&i has become a key strategy to ensure competitiveness in a global market. New business models and Distributed Manufacturing Systems (DMS) arise as a form of adaptive response to new market situations. Although R&D&I is incorporated at the strategic level, a lack of information about the management of R&D&I in distributed centers, theirs activities or organizational structure is detected. The aim of this paper is to propose a methodology to implement the Management System (MS) of R&D&I in a Distributed Manufacturing System and enhance the knowledge in relation to this topic. In turn, the management of these activities may differ from the existing manufacturing and their Quality Management System (QMS) so the quality will be discussed in terms of research, development and innovation.Gobierno de Andalucía (PAIDI)Unión Europe

Serendipitous discovery of RR Lyrae stars in the Leo V ultra-faint galaxy

During the analysis of RR Lyrae stars discovered in the High cadence Transient Survey (HiTS) taken with the Dark Energy Camera at the 4-m telescope at Cerro Tololo Inter-American Observatory, we found a group of three very distant, fundamental mode pulsator RR Lyrae (type ab). The location of these stars agrees with them belonging to the Leo V ultra-faint satellite galaxy, for which no variable stars have been reported to date. The heliocentric distance derived for Leo V based on these stars is 173 +/- 5 kpc. The pulsational properties (amplitudes and periods) of these stars locate them within the locus of the Oosterhoff II group, similar to most other ultra-faint galaxies with known RR Lyrae stars. This serendipitous discovery shows that distant RR Lyrae stars may be used to search for unknown faint stellar systems in the outskirts of the Milky Way.Comment: Accepted in ApJ Letter

A New Nasal Restriction Device Called FeelBreathe(R)Improves Breathing Patterns in Chronic Obstructive Pulmonary Disease Patients during Exercise

A device called FeelBreathe (FB)(R)was designed, developed, and patented for inspiratory muscle training. The main aim was to determine the acute responses on lung ventilation, gas exchange, and heart rate during exercise in patients with chronic obstructive pulmonary disease (COPD) with and without the use of FB. In this study, a randomized cross-over trial was performed with 18 men diagnosed with COPD (FEV(1)between 30% and 70% of its predicted value). Each participant randomly conducted two trials with 30 min of rest between them with the same protocol on a treadmill for 10 min at a constant rate of 50% of VO2peak. Each test was performed randomly and in a crossover randomized design in two different conditions: (1) oronasal breathing; and (2) nasal breathing with FB (nasal ventilatory flow restriction device). It was observed that FB had positive effects on dynamic hyperinflation, breathing pattern, and breathing efficiency, with higher expiratory and inspiratory time. Despite these differences, blood oxygen saturation percentage, oxygen uptake, and heart rate showed a similar response for both conditions during exercise. The results suggest that exercise performed with FB improved ventilatory responses compared to the oronasal mode in COPD patients. This new tool could be used during most daily tasks and exercise programs

The Proteasomal Deubiquitinating Enzyme PSMD14 Regulates Macroautophagy by Controlling Golgi-to-ER Retrograde Transport

Ubiquitination regulates several biological processes, however the role of specific members of the ubiquitinome on intracellular membrane trafficking is not yet fully understood. Here, we search for ubiquitin-related genes implicated in protein membrane trafficking performing a High-Content siRNA Screening including 1187 genes of the human “ubiquitinome” using amyloid precursor protein (APP) as a reporter. We identified the deubiquitinating enzyme PSMD14, a subunit of the 19S regulatory particle of the proteasome, specific for K63-Ub chains in cells, as a novel regulator of Golgi-to-endoplasmic reticulum (ER) retrograde transport. Silencing or pharmacological inhibition of PSMD14 with Capzimin (CZM) caused a robust increase in APP levels at the Golgi apparatus and the swelling of this organelle. We showed that this phenotype is the result of rapid inhibition of Golgi-to-ER retrograde transport, a pathway implicated in the early steps of the autophagosomal formation. Indeed, we observed that inhibition of PSMD14 with CZM acts as a potent blocker of macroautophagy by a mechanism related to the retention of Atg9A and Rab1A at the Golgi apparatus. As pharmacological inhibition of the proteolytic core of the 20S proteasome did not recapitulate these effects, we concluded that PSMD14, and the K63-Ub chains, act as a crucial regulatory factor for macroautophagy by controlling Golgi-to-ER retrograde transport

Gene discovery for facioscapulohumeral muscular dystrophy by machine learning techniques

Facioscapulohumeral muscular dystrophy (FSHD) is a neuromuscular disorder that shows a preference for the facial, shoulder and upper arm muscles. FSHD affects about one in 20-400,000 people, and no effective therapeutic strategies are known to halt disease progression or reverse muscle weakness or atrophy. Many genes may be incorrectly regulated in affected muscle tissue, but the mechanisms responsible for the progressive muscle weakness remain largely unknown. Although machine learning (ML) has made significant inroads in biomedical disciplines such as cancer research, no reports have yet addressed FSHD analysis using ML techniques. This study explores a specific FSHD data set from a ML perspective. We report results showing a very promising small group of genes that clearly separates FSHD samples from healthy samples. In addition to numerical prediction figures, we show data visualizations and biological evidence illustrating the potential usefulness of these results.Peer ReviewedPostprint (published version

Allergic hypersensitivity to cannabis in patients with allergy and illicit drug users

Producción Científica: Cannabis is the illicit drug most widely used by young people in high-income countries. Allergy symptoms have only occasionally been reported as one of the adverse health effects of cannabis use. Objectives: To study IgE-mediated response to cannabis in drug users, atopic patients, and healthy controls. Methods: Asthmatic patients sensitised to pollen, and all patients sensitised to tobacco, tomato and latex, considered as cross-reacting allergens, were selected from a data base of 21,582 patients. Drug users attending a drug-rehabilitation clinic were also included. Controls were 200 non-atopic blood donors. Specific IgE determination, prick tests and specific challenge with cannabis extracts were performed in patients and controls

An X-ray study of the SNR G344.7-0.1 and the central object CXOU J170357.8-414302

Aims. We report results of an X-ray study of the supernova remnant (SNR) G344.7-0.1 and the point-like X-ray source located at the geometrical center of the SNR radio structure. Methods. The morphology and spectral properties of the remnant and the central X-ray point-like source were studied using data from the XMM-Newton and Chandra satellites. Archival radio data and infrared Spitzer observations at 8 and 24 μm were used to compare and study its multi-band properties at different wavelengths. Results. The XMM-Newton and Chandra observations reveal that the overall X-ray emission of G344.7-0.1 is extended and correlates very well with regions of bright radio and infrared emission. The X-ray spectrum is dominated by prominent atomic emission lines. These characteristics suggest that the X-ray emission originated in a thin thermal plasma, whose radiation is represented well by a plane-parallel shock plasma model (PSHOCK). Our study favors the scenario in which G344.7-0.1 is a 6 × 103 year old SNR expanding in a medium with a high density gradient and is most likely encountering a molecular cloud on the western side. In addition, we report the discovery of a soft point-like X-ray source located at the geometrical center of the radio SNR structure. The object presents some characteristics of the so-called compact central objects (CCO). However, its neutral hydrogen absorption column (NH) is inconsistent with that of the SNR. Coincident with the position of the source, we found infrared and optical objects with typical early-K star characteristics. The X-ray source may be a foreground star or the CCO associated with the SNR. If this latter possibility were confirmed, the point-like source would be the farthest CCO detected so far and the eighth member of the new population of isolated and weakly magnetized neutron stars.Facultad de Ciencias Astronómicas y Geofísica

Negative Modulation of Macroautophagy by Stabilized HERPUD1 is Counteracted by an Increased ER-Lysosomal Network With Impact in Drug-Induced Stress Cell Survival

Macroautophagy and the ubiquitin proteasome system work as an interconnected network in the maintenance of cellular homeostasis. Indeed, efficient activation of macroautophagy upon nutritional deprivation is sustained by degradation of preexisting proteins by the proteasome. However, the specific substrates that are degraded by the proteasome in order to activate macroautophagy are currently unknown. By quantitative proteomic analysis we identified several proteins downregulated in response to starvation independently of ATG5 expression. Among them, the most significant was HERPUD1, an ER membrane protein with low expression and known to be degraded by the proteasome under normal conditions. Contrary, under ER stress, levels of HERPUD1 increased rapidly due to a blockage in its proteasomal degradation. Thus, we explored whether HERPUD1 stability could work as a negative regulator of autophagy. In this work, we expressed a version of HERPUD1 with its ubiquitin-like domain (UBL) deleted, which is known to be crucial for its proteasome degradation. In comparison to HERPUD1-WT, we found the UBL-deleted version caused a negative role on basal and induced macroautophagy. Unexpectedly, we found stabilized HERPUD1 promotes ER remodeling independent of unfolded protein response activation observing an increase in stacked-tubular structures resembling previously described tubular ER rearrangements. Importantly, a phosphomimetic S59D mutation within the UBL mimics the phenotype observed with the UBL-deleted version including an increase in HERPUD1 stability and ER remodeling together with a negative role on autophagy. Moreover, we found UBL-deleted version and HERPUD1-S59D trigger an increase in cellular size, whereas HERPUD1-S59D also causes an increased in nuclear size. Interestingly, ER remodeling by the deletion of the UBL and the phosphomimetic S59D version led to an increase in the number and function of lysosomes. In addition, the UBL-deleted version and phosphomimetic S59D version established a tight ER-lysosomal network with the presence of extended patches of ER-lysosomal membrane-contact sites condition that reveals an increase of cell survival under stress conditions. Altogether, we propose stabilized HERPUD1 downregulates macroautophagy favoring instead a closed interplay between the ER and lysosomes with consequences in drug-cell stress survival

Perinatal depression in the Spanish context: consensus report from the general council of psychology of Spain

Background: Perinatal depression is a major public health problem, with an estimated prevalence of approximately 15% during the first postpartum year. Despite the high prevalence of postpartum depression, there is no consensus regarding assessment and treatment in the Spanish context. The General Council of Psychology of Spain convened a working group of experts in the field, including both academics and healthcare professionals, to review and propose recommendations based on evidence and best practices that could be applied in the Spanish context. Method: A literature search was completed in various databases (e.g., Medline, PsychInfo) including a combination of terms related to peripartum depression (PPD) assessment and diagnosis, prevention, treatment, and cost-effectiveness. A narrative synthesis of the literature has been conducted together with a critical overview of PPD with a special focus on the Spanish context. Results: In this consensus report, developing questions including prevalence and assessment tools, comparative effectiveness of preventive and treatment interventions, and cost-effectiveness of PPD management have been analyzed. Conclusions: The General Council of Psychology of Spain network advocates the establishment of compulsory screening protocols in all the autonomous regions. Also, it is necessary to promote the inclusion in maternal education of programs for the promotion of mental well-being and selective/indicated prevention carried out by a psychology professional with specialized training in the area. This consensus document also promotes the presence of a psychology professional with specialized training in the area. Antecedentes. La depresión perinatal es un importante problema de salud pública, con una prevalencia estimada de aproximadamente el 15% durante el primer año posparto. A pesar de la gran prevalencia de depresión posparto (DPP), no existe consenso sobre la evaluación y el tratamiento en el contexto español. El Consejo General de Psicología de España convocó a un grupo de trabajo de expertos en la materia, tanto académicos como profesionales sanitarios, para revisar y proponer recomendaciones basadas en evidencias y mejores prácticas que puedan aplicarse en el contexto español. Método. Se realizó una búsqueda bibliográfica en varias bases de datos (p. ej., Medline, PsychInfo) que incluía una combinación de términos relacionados con la evaluación y el diagnóstico de la DPP, prevención, tratamiento y coste-eficacia. Se ha realizado una síntesis narrativa de la literatura junto con una visión crítica de la DPP con un enfoque especial en el contexto español. Resultados. Las preguntas de desarrollo que incluyen prevalencia y herramientas de evaluación, la eficacia comparativa de las intervenciones preventivas y de tratamiento y la relación coste-efectividad de la gestión de la PPD se han analizado en este informe de consenso. Conclusiones. La red del Consejo General de Psicología de España aboga por el establecimiento de protocolos obligatorios de cribado en todas las Comunidades Autónomas. Asimismo, es necesario promover la inclusión en la educación materna de programas de promoción del bienestar mental y la prevención selectiva indicada llevadas a cabo por un profesional de la psicología con formación especializada en el área
