Institutions and business customer experience: the role of interfunctional coordination and service co-design.

This paper contributes to a better understanding of the complex phenomenon of institutions and the moderation of the main antecedents of business customer experience. Following a combination of literature review and three fieldworks, the main antecedents of business customer experience have emerged: interfunctional coordination, customer engagement and participation in the co-design of services. The role of institutions (level of formalisation) has also been considered as a possible moderator. Consequently, a conceptual framework has been developed which includes seven research propositions. The first four research propositions are related to the main elements of the model and suggest new relationships among constructs. The other three research propositions are suggested and empirically examined using Fuzzy-Set Qualitative Comparative Analysis to find causal configurations and to identify pathways that lead to business customer experience. Necessity and sufficiency of conditions that lead to a positive business customer experience are discussed for both scenarios of high and low formalisation of institutions

Un acercamiento a la comprensión de la psicología del deporte en espana. Análisis de la revista de psicología del deporte 1992-1999

En este trabajo abordamos la trayectoria científica de la Revista de Psicología del Deporte desde sus orígenes en el año 1992. Su análisis resulta de especial relevancia dado que en nuestro país esta disciplina aún mantiene un desarrollo creciente por su juventud y, sobre todo, porque tras unas pocas décadas de trabajo intenso, las perspectivas de futuro son las de una consolidación cada vez más clara de los tópicos científicos que aborda. Desde este planteamiento se ha realizado un análisis bibliométrico de diferentes aspectos, que nos ayudarán a comprender mejor el desarrollo mencionado. Para ello hemos descrito aspectos esenciales en cualquier análisis de este tipo, como son los autores más productivos, las instituciones donde se genera mayor producción científica, y las temáticas fundamentales de estudio, entre otros. Los resultados apoyan la primera afirmación de que efectivamente la consolidación de esta disciplina es un hecho.In the present work we approach the scientistic trayectory of the Revista de Psicología del Deporte (Journal of the Psychology of Sport) from its origins in the year of 1992. It research becomes to special outstanding because in our country this discipline still keeps its growing development due to its youth and, specially, because after a few decades of intense work, the future perspectives are a more consolidation of the scientistic topics approached. From this view it has been made an bibliometic analysis of different sides, that will help to a better understanding of the mentioned development. For this aim it has been described the essential aspects in every kind of analysis, as the most productive authors, the institutions where the major scientistic production is made, the fundamental subjects of study, among others. The results are supporting the first confirmation that, in fact, the consolidation of this discipline is real

Pomegranate Extract Improves Maximal Performance of Trained Cyclists after an Exhausting Endurance Trial: A Randomised Controlled Trial

The efficacy of pomegranate (Punica granatum) extract (PE) for improving performance and post-exercise recovery in an active population was equivocal in previous studies. In this study, a randomised, double-blinded, placebo-controlled, balanced, cross-over trial with two arms was conducted. Eligibility criteria for participants were as follows: male, amateur cyclist, with a training routine of 2 to 4 sessions per week (at least one hour per session). The cyclists (n = 26) were divided into treatment (PE) and placebo (PLA) groups for a period of 15 days. After physical tests, the groups were exchanged after a 14-day washout period. Exercise tests consisted of endurance bouts (square-wave endurance exercise test followed by an incremental exercise test to exhaustion) and an eccentric exercise drill. The objective was to assess the efficacy of PE in performance outcomes and post-exercise muscular recovery and force restoration after a prolonged submaximal effort. Twenty-six participants were included for statistical analysis. There was a statistically significant difference in total time to exhaustion (TTE)(17.66–170.94 s, p < 0.02) and the time to reach ventilatory threshold 2 (VT2)(26.98–82.55 s, p < 0.001), with greater values for the PE compared to the PLA group. No significant results were obtained for force restoration in the isokinetic unilateral low limb test. PE, after a prolonged submaximal effort, may be effective in improving performance outcomes at maximal effort and might help to restore force in the damaged muscles.Actividad Física y Deport

Endoglin Protein Interactome Profiling Identifies TRIM21 and Galectin-3 as New Binding Partners

This article belongs to the Special Issue TGF-beta/BMP Signaling PathwayEndoglin is a 180-kDa glycoprotein receptor primarily expressed by the vascular endothelium and involved in cardiovascular disease and cancer. Heterozygous mutations in the endoglin gene (ENG) cause hereditary hemorrhagic telangiectasia type 1, a vascular disease that presents with nasal and gastrointestinal bleeding, skin and mucosa telangiectases, and arteriovenous malformations in internal organs. A circulating form of endoglin (alias soluble endoglin, sEng), proteolytically released from the membrane-bound protein, has been observed in several inflammation-related pathological conditions and appears to contribute to endothelial dysfunction and cancer development through unknown mechanisms. Membrane-bound endoglin is an auxiliary component of the TGF-ß receptor complex and the extracellular region of endoglin has been shown to interact with types I and II TGF-ß receptors, as well as with BMP9 and BMP10 ligands, both members of the TGF-ß family. To search for novel protein interactors, we screened a microarray containing over 9000 unique human proteins using recombinant sEng as bait. We find that sEng binds with high affinity, at least, to 22 new proteins. Among these, we validated the interaction of endoglin with galectin-3, a secreted member of the lectin family with capacity to bind membrane glycoproteins, and with tripartite motif-containing protein 21 (TRIM21), an E3 ubiquitin-protein ligase. Using human endothelial cells and Chinese hamster ovary cells, we showed that endoglin co-immunoprecipitates and co-localizes with galectin-3 or TRIM21. These results open new research avenues on endoglin function and regulation.This work was supported by grants from Ministerio de Ciencia, Innovación y Universidades of Spain (SAF2013-43421-R to CB and SAF2017-84183-R to MQ), Centro de Investigación Biomédica en Red de Enfermedades Raras (CIBERER; ISCIII-CB06/07/0038 to CB and contract CNV-234-PRF-360 to LR-L) and Consejo Superior de Investigaciones Científicas (CSIC; 201920E022 to CB).

The potential role of the adipokine HMGB1 in obesity and insulin resistance. Novel effects on adipose tissue biology

Discovery of the adipose tissue as a major source of signaling molecules almost three decades ago set a novel physiological paradigm that paved the way for the identification of metabolic organs as endocrine organs. Adipocytes, the main adipose tissue cell type, do not only represent the principal site of energy storage in form of triglycerides, but also produce a variety of molecules for short and long distance intercellular communication, named adipokines, which coordinate systemic responses. Although the best known adipokines identified and characterized hitherto are leptin and adiponectin, novel adipokines are continuously being described, what have significantly helped to elucidate the role of adipocyte biology in obesity and associated comorbidities. One of these novel adipokines is high-mobility group box 1 (HMGB1), a ubiquitous nuclear protein that has been recently reported to be dysregulated in obese dysfunctional adipocytes. Although the classical function of HMGB1 is related to inflammation and immunity, acting as an alarmin, novel advances evidence an active implication of HMGB1 in tissue remodeling and fibrosis. This review summarizes the current evidence on the mechanisms controlling HMGB1 release, as well as its role as a regulator of adipocyte function and extracellular matrix remodeling, with special emphasis on the potential of this novel adipokine as a target in the obesity treatment

Ozarowski (NHMFL) for his EPR software SPIN.A new CoII2YIII2 complex with the formula [{Co(u-L)Y(NO3)}2(u-CO3)2]·2CH3OH·2H2O (where H2L = N,N’,N”-trimethyl-N,N”-bis(2-hydroxy-3-methoxy-5-methylbenzyl) diethylenetriamine) has been prepared and its structure solved by single-crystal X-Ray diffraction. The tetranuclear structure is formed by the connection of two [Co(μ-L)Y(NO3)] dinuclear units through two carbonate bridging ligands, which exhibit a tetradentate coordination mode. The CoII ion exhibits a slightly distorted octahedral CoN3O3 coordination environment. From direct-current magnetic data a large and positive axial anisotropy parameter was extracted (D = +82.62 cm-1) and its sign unambiguously confirmed by HFEPR spectra and ab initio calculations. The extracted D value is rather larger than those previously reported for the analogous CoIIYIII dinuclear complexes, which agrees with the fact that the CoII ion in the CoII2YIII2 complex exhibits the lower distortion from the octahedral geometry in this family of CoIInYIIIn complexes. Dynamic ac magnetic measurements show that the reported compound presents field-induced slow relaxation for magnetization reversal, through a combination of direct and Raman processes. Magnetic measurements on the diluted magnetic counterpart (Zn/Co = 10/1) show the persistence of these processes, pointing out their single-ion origin. The Raman relaxation process for the Co2Y2 complex is faster that those observed for the CoY dinuclear counterparts. This fact and the existence of the persistent direct process at low temperature could be because the former molecule is larger and flexible than the latter ones.Maria de Maeztu grant MDM-2017-0767Ministerio de Educación, Cultura y Deporte PGC2018-093863-B-C21, PGC2018-102052-B-C21Junta de Andalucía FQM-195, P11-FQM-7756University of GranadaMinisterio de Economía y Competitividad CTQ2014-56312-P, IJCI-2014-19485Generalitat de Catalunya SGR2017-1289, 2017 BP 00080National Science Foundation DMR 115749

Plant catalases as NO and H2S targets

Catalase is a powerful antioxidant metalloenzyme located in peroxisomes which also plays a central role in signaling processes under physiological and adverse situations. Whereas animals contain a single catalase gene, in plants this enzyme is encoded by a multigene family providing multiple isoenzymes whose number varies depending on the species, and their expression is regulated according to their tissue/organ distribution and the environmental conditions. This enzyme can be modulated by reactive oxygen and nitrogen species (ROS/RNS) as well as by hydrogen sulfide (H2S). Catalase is the major protein undergoing Tyr-nitration [post-translational modification (PTM) promoted by RNS] during fruit ripening, but the enzyme from diverse sources is also susceptible to undergo other activity-modifying PTMs. Data on S-nitrosation and persulfidation of catalase from different plant origins are given and compared here with results from obese children where S-nitrosation of catalase occurs. The cysteine residues prone to be S-nitrosated in catalase from plants and from bovine liver have been identified. These evidences assign to peroxisomes a crucial statement in the signaling crossroads among relevant molecules (NO and H2S), since catalase is allocated in these organelles. This review depicts a scenario where the regulation of catalase through PTMs, especially S-nitrosation and persulfidation, is highlighted

La interpretación geomorfológica en la cartografía de peligro de inundación

La interpretación geomorfológica de los procesos fluviales resulta fundamental para la elaboración de cartografía de peligro de inundación. Los ríos se comportan de una manera dinámica y pueden variar su topografía de una crecida a otra. Por ello, una cartografía de peligrosidad, excesivamente dependiente de modelos hidráulicos e hidrológicos, puede resultar ineficaz y quedarse obsoleta tras un suceso de alta energía. Conocer los elementos de geomorfología fluvial, así como sus procesos asociados permite una previsión a más largo plazo y una aproximación más realista al riesgo. En este trabajo se presentan ejemplos de interpretación geomorfológica de formas y procesos fluviales, en clave de peligro de inundación. Se han seleccionado tres cuencas de diferentes entornos morfoclimáticos que, a distintas escalas, permiten ilustrar algunos puntos donde la geomorfología propicia un determinado proceso y, en consecuencia, condiciona el tipo de peligro de la zona. La interpretación geomorfológica se ha llevado a cabo mediante trabajo de campo, de laboratorio y a partir de imágenes de satélite (RADARSAT e Ikonos)
