Transgresión moral y enfermedad en los países nórdicos en la temprana Edad Moderna
2009
This article seeks to understand how people in the early modern age interpreted the nature of illness and the role that morality played in these interpretations. From this point of view illnesses were not only psycho-physical states or subjects for medical diagnosis but they were also subjects for narratives or stories through which people tried to understand what had caused their illness, and why it was happening to them. Illnesses were understood as strictly connected with the patient's character and were regarded as possible consequences of his personality. On the other hand, the interpretations also emphasised the ambivalence of a healer. Personal experiences and an understanding of one…
Exploring the affordances of Numbas for mathematical learning: a case study
2020
International audience; The computer-based assessment system Numbas offers new learning possibilities in mathematics education by means of formative feedback. The paper proposes a theoretical framework that captures the affordances emerging from students' interactions with Numbas at the technological, mathematical, and assessment level. The aim of the paper is to explore the affordances that arise from these levels using the theoretical framework as a lens. Based on the results, preliminary conclusions and recommendations for future work are proposed.
The Big Five Traits and Their Ramifications
2020
This chapter focuses on the analysis of the Big Five traits, discussed in relation to the classical and modern views on the trait hierarchy. In the next section the socioaffective, cognitive and educational, as well as behavioural ramifications of each trait are outlined in order to create a general background for the analysis of the Big Five in the foreign language learning context. In the light of the above considerations, each trait appears to have beneficial, and also negative effects for the individual’s functioning. Finally, a discussion of age and gender differences in the Big Five, and their development across the lifespan is offered.
Subjective well-being key elements of Successful Aging: A study with Lifelong Learners older adults from Costa Rica and Spain.
2019
Abstract Subjective well-being is a major psychological construct in the research tradition. Along with literature, authors have distinguished between hedonic and eudaimonic well-being. The aim of this study is to determine the role of some psychosocial variables plays in the perceived well-being is conceived from a hedonic or a eudaimonic perspective. The sample consisted of 1016 people of 55 years and older in a Spanish sample and 277 people of 55 years old or older from a Costa Rican sample. Both samples were part of the Longitudinal Older Learners (LOL) study. A structural model with latent variables was estimated with Mplus. The results point out that, the traditional variables include…
miR-126-3p and miR-21-5p as Hallmarks of Bio-Positive Ageing; Correlation Analysis and Machine Learning Prediction in Young to Ultra-Centenarian Sici…
2022
Human ageing can be characterized by a profile of circulating microRNAs (miRNAs), which are potentially predictors of biological age. They can be used as a biomarker of risk for age-related inflammatory outcomes, and senescent endothelial cells (ECs) have emerged as a possible source of circulating miRNAs. In this paper, a panel of four circulating miRNAs including miR-146a-5p, miR-126-3p, miR-21-5p, and miR-181a-5p, involved in several pathways related to inflammation, and ECs senescence that seem to be characteristic of the healthy ageing phenotype. The circulating levels of these miRNAs were determined in 78 healthy subjects aged between 22 to 111 years. Contextually, extracellular miR-1…
Development and validation of prediction model to estimate 10-year risk of all-cause mortality using modern statistical learning methods: a large pop…
2021
Abstract Background In increasingly ageing populations, there is an emergent need to develop a robust prediction model for estimating an individual absolute risk for all-cause mortality, so that relevant assessments and interventions can be targeted appropriately. The objective of the study was to derive, evaluate and validate (internally and externally) a risk prediction model allowing rapid estimations of an absolute risk of all-cause mortality in the following 10 years. Methods For the model development, data came from English Longitudinal Study of Ageing study, which comprised 9154 population-representative individuals aged 50–75 years, 1240 (13.5%) of whom died during the 10-year follo…
Neuroprotective effects of behavioural training and nicotine on age-related deficits in spatial learning.
2006
Studies in humans and animals show a clear decline in spatial memory with age and several approaches have been adopted to alleviate this impairment. The purpose of our review is to assess the studies that have suggested the possible neuroprotective actions of behavioural training and nicotine-applied both independently and in conjunction-on age-related deficits in spatial learning. Both spatial pretraining and nonspatial experiences influence an animal's performance in spatial tasks. In aged rats, the experience of training in the water maze task increases the number of newly generated neurons in the hippocampus. The neuroprotective effects of nicotine have been demonstrated in both in-vitr…
Cannabinoid receptor 1 deficiency in a mouse model of Alzheimer's disease leads to enhanced cognitive impairment despite of a reduction in amyloid de…
2012
Alzheimer's disease (AD) is characterized by amyloid-beta deposition in amyloid plaques, neurofibrillary tangles, inflammation, neuronal loss, and cognitive deficits. Cannabinoids display neuromodulatory and neuroprotective effects and affect memory acquisition. Here, we studied the impact of cannabinoid receptor type 1 (CB1) deficiency on the development of AD pathology by breeding amyloid precursor protein (APP) Swedish mutant mice (APP23), an AD animal model, with CB1-deficient mice. In addition to the lower body weight of APP23/CB1(-/-) mice, most of these mice died at an age before typical AD-associated changes become apparent. The surviving mice showed a reduced amount of APP and its …
Anxiolytic-like effects of acute and chronic GABA transporter inhibition in rats.
2002
Acute GABA transporter inhibition can induce anxiolytic-like behaviors. The present analysis addressed whether chronic treatment (23 days via drinking water) with a GABA transporter inhibitor affects rat behavior similar to acute treatment and interferes with additional benzodiazepine-receptor agonistic treatment. Seventy-one rats divided into seven groups were acutely treated with either vehicle, diazepam (2 mg/kg), zolpidem (0.05 mg/kg), tiagabine (19 mg/kg) or chronically with tiagabine with or without acute diazepam or zolpidem. Animals were behaviorally characterized in an elevated plus-maze. None of the treatments induced changes in the activity of the animals. Acute and chronic treat…
Effects of pre- and postnatal exposure to 5-methoxytryptamine and early handling on an object-place association learning task in adolescent rat offsp…
2007
A reduction in 5-HT1A receptor response enhances learning and memory performance in rats. Pre- and postnatal treatment with 5-methoxytryptamine (5MT), a non-selective serotonergic agonist, and early handling, reduce the number of 5-HT1A receptors in neonatal and pre-pubertal rat progeny. The aim of this study was to investigate in adolescent male rats the consequences of pre- and postnatal treatment with 5MT and its interaction with early handling on an object-place association learning task, the "Can test", a motivated, non-aversive, spatial/object discrimination task. Results show that a single daily injection of 5MT from gestational days 12 to 21 (1 mg/kg s.c.) and from postnatal days 2 …
