Students’ physical activity intensity and sedentary behaviour by physical self-concept profiles: A latent profile analysis. [Intensidad de la activid…
2020
Abstract Aims of this study were to identify student clusters in physical appearance, sport competence, global physical self-concept and self-esteem, and to examine whether different physical self-concept groups differ in their moderate-to-vigorous physical activity (MVPA) and sedentary behaviour. Participants of the study were 211 boys and 183 girls aged 13-16 years. MVPA and sedentary behaviour were monitored by GT3X accelerometers during seven days. Participants’ physical self-concept was measured by the short Physical Self-Description Questionnaire. Latent profile analyses revealed a four-cluster solution: 1) “low sport competence, moderate global physical self-concept and self-esteem, …
An undergraduate thesis training course for faculty reduces variability in student evaluations
2020
Abstract Background The undergraduate thesis evaluation process is one of the most prevalent weak points in universities; the literature indicates the need to orient undergraduate thesis evaluators through specific training initiatives. Objectives The aim of this study was to analyze the discrepancies between the grades awarded by undergraduate thesis supervisors and by the panel of faculty examiners, and the effect of training targeted to faculty members. Design and methods A cross-sectional study was performed during the 2015–2016 academic year in a Spanish Nursing School. Settings and participants We analyzed the mean grades from undergraduate thesis evaluation rubrics and the effects of…
Photosensitive Alternative Splicing of the Circadian Clock Gene timeless Is Population Specific in a Cold-Adapted Fly, Drosophila montana.
2018
To function properly, organisms must adjust their physiology, behavior and metabolism in response to a suite of varying environmental conditions. One of the central regulators of these changes is organisms' internal circadian clock, and recent evidence has suggested that the clock genes are also important in the regulation of seasonal adjustments. In particular, thermosensitive splicing of the core clock gene <i>timeless</i> in a cosmopolitan fly, <i>Drosophila melanogaster</i> , has implicated this gene to be involved in thermal adaptation. To further investigate this link we examined the splicing of <i>timeless</i> in a northern malt fly species, <i&…
Acute in vivo administration of a fish oil-containing emulsion improves post-ischemic cardiac function in n-3-depleted rats
2006
International audience; A novel i.v. lipid preparation (MCT:FO) containing 80% medium chain-triacylglycerols and 20% fish oil was recently developed to rapidly replenish cell membrane phospholipids with omega 3 (n-3) polyunsaturated fatty acids (PUFA). In regard of this property, we investigated the effect of a single i.v. administration of MCT:FO on the recovery of cardiac function after ischemia in control and n-3-depleted rats. Results were compared with those obtained either with a control preparation, where FO was replaced by triolein (MCT:OO), or with saline. Saline (1 ml) or lipid preparation (also 1 ml) was injected as a bolus via the left saphenous vein. After 60 min the heart was …
Resilience as a predictor of Quality of Life in participants with borderline personality disorder before and after treatment.
2021
Abstract Background Studies have suggested that psychotherapy improves the Quality of Life (QoL) of participants with Borderline Personality Disorder (BPD). However, there are no studies on the differential efficacy of treatments on the QoL of participants with BPD. Moreover, the relationship between QoL and resilience has rarely been studied in participants with BPD. Objectives: a) to examine whether people with BPD have worse QoL than the non-clinical population; b) to examine whether there are statistically significant differences between Dialectical Behavioural Therapy (DBT), Systems Training for Emotional Predictability and Problem Solving (STEPPS), or Cognitive Behavioural Therapy-Tre…
Sensitivity to change of two depression rating scales for stroke patients.
2010
Objective: To assess the sensitivity to change of two depression scales for stroke patients: the Aphasic Depression Rating Scale (ADRS), which is a 9-item external assessment, and the Visual Analog Mood Scale (VAMS), which is a visual self-assessment scale. Patients: Forty-nine stroke patients admitted to two rehabilitation units. Methods: Symptoms of depression were assessed twice at a one-month interval (D0—D30) using the ADRS, the VAMS, and by a trained psychologist (PSY). Sensitivity to change was assessed by effect size and standardized response mean. A one-way ANOVA on ranks was performed to determine if the scales distinguished between deteriorated, stable and improved patient statu…
Memory for time intervals is impaired in left hemi-Parkinson patients.
2004
The basal ganglia have been proposed as one of the neural correlates of timekeeping functions. Both encoding and memory retrieval components for time perception are impaired in Parkinson's disease (PD). The aim of our study was to investigate in hemi-Parkinsonian patients the existence of a specific alteration in memory for time depending on the affected side, to better understand the contribution of the left or right basal ganglia circuits in different components of time perception. Right and left hemi-PD patients performed a time reproduction task in which they were required to reproduce in the same session short (5 s) and long (15 s) time intervals, in off- and on-therapy condition. Whil…
Behaviour-change interventions in primary care: Influence on nutrition and on the metabolic syndrome definers
2011
The purpose of this paper was to examine whether interventions influenced patients' (i) consumption of fish; whole grain products; fruits and vegetables; (ii) overall nutrition, that is, the three former as an index; and (iii) clinical outcomes in terms of metabolic syndrome definers. A questionnaire was delivered to adult patients entering the nine health centres on November 2006 (n = 1211). During the year the ward personnel conducted intervention on patients with unhealthy habits. The 12-month follow up was conducted by mailings. Also clinical data of pre- and post-intervention values of metabolic syndrome definers were collected. For the analyses, intervention was divided into brief (≤ …
Carotenoid trade-off between parasitic resistance and sexual display: an experimental study in the blackbird (Turdus merula).
2008
Many parasites depress the expression of the carotenoid-based colour displays of their hosts, and it has been hypothesized that animals face a trade-off in carotenoid allocation between immune functions and ‘degree of ornamentation’. While numerous correlative studies suggest that parasite infection decreases the intensity of carotenoid-based colour displays, the existence of this trade-off has never been demonstrated experimentally in a host–parasite model. In this study, we used the blackbird ( Turdus merula ) and Isospora (an intestinal parasite) to assess whether this trade-off does indeed exist. Blackbirds were supplemented with carotenoids while simultaneously being exposed to parasi…
Long-term effects on motor cortical excitability induced by repeated muscle vibration during contraction in healthy subjects
2008
article i nfo Objective: The effects of a novel repeated muscle vibration intervention (rMV; 100 Hz, 90 min over 3 consecutive days) on corticomotor excitability were studied in healthy subjects. Methods: rMV was applied over the flexor carpi radialis (FCR) during voluntary contraction (experiment 1), during relaxation and during contraction without vibration (experiment 2). Focal transcranial magnetic stimulation (TMS) was applied before rMV and one hour, and one, two and three weeks after the last muscle vibration intervention. At each of these time points, we assessed the motor map area and volume in the FCR, extensor digitorum communis (EDC) and abductor digiti minimi (ADM). Short-inter…
