Bases hormonals de la conducta prosocial: una revisió de la literatura
2016
Resumen: En los últimos años se ha intensificado el estudio de las conductas prosociales, incluyendo una mayor atención a los aspectos neuropsicobiológicos implicados en tales conductas, para entender su funcionamiento, así como para fomentarlas. Las investigaciones también pueden proporcionar una aproximación a la búsqueda de tratamientos más acertados a aquellas enfermedades en las que la cognición social se ve alterada. El objetivo principal del presente trabajo es establecer el estado actual de la cuestión, revisando la literatura publicada sobre las hormonas que influyen a la conducta prosocial, tanto en animales como en humanos. Los resultados de la investigación apuntan a la oxitocin…
Influence of cultivation techniques and use of two nutritive solution with different electrical conductivity on the production and quality of cucumbe…
2009
The most suitable techniques and use of F1 hybrids enable greenhouse production to achieve high yields, with crops all year round. In Sicily, greenhouse production of cucumber is for fresh use (slicers), producing large fruit. The cultivation technique most suited to greenhouses is the vertical single stem. However, an innovative technique being proposed is of cultivation on a trellis, eliminating lower branches, and training the remaining branches upwards (vertical shoot positioning, VSP). Cucumbers in the south of Italy are grown as the main crop or as a catch crop between 2 main crops. The crop should be rotated on the same soil only after 3-4 years with another crop, unless the land is …
Plagiarism and predatory journals: A threat to scientific integrity
2018
This article presents an analysis of the concept of plagiarism in order to show the wide spectrum of manifestations that can be considered as such when committing a transgression of intellectual property, carried out with the intention of deceiving the authors’ true contribution and the originality and novelty of the information. It describes the different circumstances in which intentional plagiarism has occurred, and the damage that this misconduct causes in the credibility of the scientific system, in which authorship credit is the foundation of the academic career, of the prestige of the author in the scientific community, and the basis for financing research. Some circumstances are fav…
Looking into the eyes of a conductor performing Lerdahl's “Time after Time”
2010
The eye movements of a conductor were tracked during a performance of Lerdahl's “Time after time”. The analysis of the data revealed that, for most of the time, the conductor was looking at the score, rather than the performers. Most of the score-reading was in anticipation of the music to be played. Micro- and macro-anticipations could be defined, the former being between 2 to 5 seconds in advance, the later being more than 5 seconds in advance. The largest visual anticipations were as long as 10 seconds. The longer anticipations were found to correspond to the occurrence of those thematic cells the conductor considered to be of expressive importance for the piece. This suggests that the …
Trait driving anger and driving styles among Colombian professional drivers
2019
Abstract This study analyzes the association between trait driving anger and driving styles in a sample of Colombian professional drivers. Additionally, the internal and external validity of the Deffenbacher's Driving Anger Scale (DAS-14) was examined in the study population. The DAS-14 and the Spanish Version of the Multidimensional Driving Style Inventory (S-MDSI) were administered to 492 urban bus and taxi operators. Average trait driving anger scores in the study population were similar to those reported in previous validation studies from Spain, Argentina, China, and Malaysia. After deleting three cross-loaded items, confirmatory factor analyses revealed a three-dimensional latent stru…
Quantum memories with zero-energy Majorana modes and experimental constraints
2016
In this work we address the problem of realizing a reliable quantum memory based on zero-energy Majorana modes in the presence of experimental constraints on the operations aimed at recovering the information. In particular, we characterize the best recovery operation acting only on the zero-energy Majorana modes and the memory fidelity that can be therewith achieved. In order to understand the effect of such restriction, we discuss two examples of noise models acting on the topological system and compare the amount of information that can be recovered by accessing either the whole system, or the zero-modes only, with particular attention to the scaling with the size of the system and the e…
Emotional lability in children and adolescents with attention deficit/hyperactivity disorder (ADHD): clinical correlates and familial prevalence
2010
Background: The goal of this study was to investigate the occurrence, severity and clinical correlates of emotional lability (EL) in children with attention deficit/hyperactivity disorder (ADHD), and to examine factors contributing to EL and familiality of EL in youth with ADHD. Methods: One thousand, one hundred and eighty-six children with ADHD combined type and 1827 siblings (aged 6–18 years) were assessed for symptoms of EL, ADHD, associated psychopathology and comorbid psychiatric disorders with a structured diagnostic interview (PACS) as well as parent and teacher ratings of psychopathology (SDQ; CPRS-R:L; CTRS-R:L). Analyses of variance, regression analyses, ?2-tests or loglinear mod…
Cisplatin-induced peripheral neuropathy: neuroprotection by erythropoietin without affecting tumour growth
2007
This study examined the dose-dependent efficacy of erythropoietin (EPO) for preventing and/or treating cisplatin (CDDP) induced peripheral neurotoxicity (CINP), and its influence on tumour treatment and growth. Rats received eight intraperitoneal (ip) injections of 2 mg/kg CDDP twice weekly. EPO co-administered (50 or 10 microg/kg ip, three times/week) had a dose-dependent effect, partially preventing CINP, but 0.5 microg/kg ip was not effective. The neuroprotective effect lasted at least 5 weeks after the last dose of EPO and CDDP. In addition, EPO (50 microg/kg ip three times/week) after the last injection of CDDP still induced a significant recovery of CINP. In a separate experiment in r…
Dofetilide effects on the inhibition by trains of subthreshold conditioning stimuli.
2004
We investigated the electrophysiological actions of dofetilide upon the ventricular myocardium to determine whether the drug modifies the inhibitory effects of subthreshold stimuli trains upon ventricular refractoriness. In nine Langendorff perfused rabbit hearts, ventricular epicardial electrodes were used to determine the following parameters at baseline and during dofetilide perfusion (0.5 micromolar): effective (ERP) and functional (FRP) refractory periods, conduction velocity (CV), wavelength (WL), and ERP prolongation (inhibitory effect) induced by subthreshold stimuli trains (STr) at pulse frequencies of 100, 300, and 600 Hz. Dofetilide significantly prolongs ventricular refractorine…
