Candidate superdeformed band in 28Si
2012
Recent antisymmetrized molecular dynamics (AMD) calculations for 28Si suggest the presence of a superdeformed (SD) band with a dominant 24Mg + α clustering for its configuration, with firm predictions for its location and associated moment of inertia. This motivates a review of the experimental results reported in the literature with a particular focus on 24Mg(α,γ ) studies, as well as on α-like heavy-ion transfer reactions such as 12C(20Ne,α) 28Si. Combining this information for the first time leads to a set of candidate SD states whose properties point to their α-cluster structure and strong associated deformation. Analysis of data from Gammasphere allows the electromagnetic decay of thes…
Amygdaloid projections to the ventral striatum in mice: direct and indirect chemosensory inputs to the brain reward system
2011
Rodents constitute good models for studying the neural basis of socio-sexual behaviour. Recent findings in mice have revealed the molecular identity of the some pheromonal molecules triggering intersexual attraction. However, the neural pathways mediating this basic socio-sexual behaviour remain elusive. Since previous work indicates that the dopaminergic tegmento-striatal pathway is not involved in pheromone reward, the present report explores alternative pathways linking the vomeronasal system with the tegmento-striatal system (the limbic basal ganglia) by means of tract-tracing experiments studying direct and indirect projections from the chemosensory amygdala to the ventral striato-pall…
Trans-Contextual Model Predicting Change in Out-of-School Physical Activity: A One-Year Longitudinal Study
2021
The aim of the current study was to test the long-term predictive validity of the trans-contextual model in accounting for variance in adolescents’ out-of-school physical activity measured by self-report and accelerometer based-devices over a one-year period. Secondary school students ( N = 265) aged 11 to 15 years completed a three-wave survey on two occasions in time, spanning a one-year interval, measuring perceived autonomy support in physical education (PE), peer and parent autonomy support in leisure-time, autonomous and controlled motivation in PE and leisure-time, attitude, subjective norms, perceived behavioural control, intention, and out-of-school physical activity both by sel…
Students’ physical activity intensity and sedentary behaviour by physical self-concept profiles : A latent profile analysis
2020
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, and high …
Estudio de las características psicológicas y sociales del cuidador principal de niños con enfermedades neurológicas dependientes de nutrición entera…
2013
El cuidado en el domicilio de un niño con una discapacidad portador de nutrición enteral domiciliaria a través de gastrostomía (NED-G) tiene una importante repercusión en la familia, especialmente en el cuidador principal que en la mayoría de los casos es la madre, ya que implica un impacto sobre sus aspiraciones personales, salud física, relaciones sociales y culturales, oportunidades profesionales y sus recursos económicos. La hipótesis de nuestro estudio fue que los cuidadores principales de niños con una enfermedad neurológica con NED-G pueden presentar alteraciones psicológicas (ansiedad, depresión, distrés psicológico y sensación de sobrecarga) que repercuten en su salud psicológica y…
Ultrasound and supercritical fluids as useful tools to recover nutrients and bioactive compounds from aquaculture and marine side streams
2021
Los productos provenientes de la acuacultura, así como de los subproductos marinos contienen una cantidad muy importante y diversa de compuestos con diferentes actividades biológicas, atrayendo así el interés de las industrias alimentaria, farmacéutica y cosmética, entre otras. Para beneficiarse de éstos, especialmente subproductos del pescado y microalgas, como fuente potencial de diversos compuestos antioxidantes, proteínas, carbohidratos, pigmentos, compuestos fenólicos, etc., la extracción en sí juega un papel crucial, fundamentalmente cuando se trata de tecnologías verdes y sostenibles. Las técnicas de extracción convencionales implican el uso de disolventes orgánicos y requieren tiemp…
Nuorten salibandypelaajien nuuskan käyttö ja siihen yhteydessä olevat tekijät
2017
Suomalaisten nuorten tupakointi on vähentynyt, kun taas nuuskakokeilut ja nuuskan käyttö ovat lisääntyneet. Aiempien tutkimusten mukaan nuuskan käyttö on yleistä myös urheilijoiden keskuudessa. Tässä tutkimuksessa tarkasteltiin nuorten salibandypelaajien nuuskakokeiluja ja nuuskan käyttöä sekä siihen yhteydessä olevia tekijöitä. Tutkimusaineisto kerättiin sähköisellä kyselylomakkeella joulukuun 2016 ja tammikuun 2017 välisellä ajalla. Kyselyyn vastasi 449 pelaajaa (poikia 302, tyttöjä 147, keski-ikä 16,7 vuotta). Aineiston analysoinnissa hyödynnettiin ristiintaulukointeja ja khiin neliö-testiä sekä logistista regressioanalyysia. Salibandya pelaavista 13–20-vuotiaista nuorista 39 prosenttia …
A common biological basis of obesity and nicotine addiction
2013
Contains fulltext : 128630.pdf (Publisher’s version ) (Open Access) Smoking influences body weight such that smokers weigh less than non-smokers and smoking cessation often leads to weight increase. The relationship between body weight and smoking is partly explained by the effect of nicotine on appetite and metabolism. However, the brain reward system is involved in the control of the intake of both food and tobacco. We evaluated the effect of single-nucleotide polymorphisms (SNPs) affecting body mass index (BMI) on smoking behavior, and tested the 32 SNPs identified in a meta-analysis for association with two smoking phenotypes, smoking initiation (SI) and the number of cigarettes smoked …
The association of cannabis use with fast-food consumption, overweight, and obesity among adolescents aged 12-15 years from 28 countries
2022
Background: Cannabis legalization and use have risen globally. However, the association between cannabis use, eating behaviors and body weight among adolescents is yet unexplored. Objectives: This study examined the association between cannabis use, fast-food consumption, overweight and obesity in 28 countries using data from the 2010–2016 Global School-Based Student Health Survey. Methods: Multivariable logistic regression and meta-analysis were performed among a sample of 83,726 adolescents (48.7% females) aged 12–15 years, mean (SD) age of 13.8 (0.9) years. Results: The overall prevalence of cannabis use (in past 30 days) and fast-food consumption (in past 7 days) were 2.8% and 57.3% res…
