Corticosterone levels and behavioral changes induced by simultaneous exposure to chronic social stress and enriched environments in NMRI male mice
2016
Environmental enrichment (EE) is an experimental model which is believed to counteract some of the effects induced by stressors, although few studies have exposed rodents simultaneously to EE and stress. Our aim was to compare the short- and long-term effects of different housing conditions in mice submitted to chronic stress. 128 NMRI male mice arrived at our laboratory on postnatal day (PND) 21. During Phase I (PND 28), animals were randomly assigned to four experimental conditions: 1) EE+STRESS: mice housed in EE and submitted to social stress (n=32); 2) EE+NO STRESS: mice housed in EE without stress (n=32); 3) SE+STRESS: mice maintained in standard conditions (SE) and submitted to socia…
Physical activity and environmental enrichment: Behavioural effects of exposure to different housing conditions in mice.
2020
Enriched environments and exercise provide complex environmental stimulation that can induce emotional and cognitive changes; however, few studies have evaluated the effects of these two components on other behaviours, such as novelty seeking or pain sensitivity. The aim of the present study was to investigate the influence of voluntary physical activity provided through different housing conditions on anxiety, locomotor activity, pain sensitivity, and exploration. Male mice at postnatal day (PND) 21 and were randomly assigned to one of four different conditions on PND 28: Marlau cages (MC), a standardized cage designed to provide a complex environment; physical exercise in large groups (PE…
Cuidado de pacientes oncológicos: una revisión sobre el impacto de la situación de estrés crónico y su relación con la personalidad del cuidador y ot…
1970
Objetivo: La incidencia y prevalencia de enfermedades de larga duración como el cáncer se ha incrementado en los últimos años. En este contexto, nuestro principal objetivo será el análisis de las principales consecuencias que la exposición a una situación de estrés crónico, como es el cuidado de un paciente oncológico, tiene sobre la salud psicosocial y la función cognitiva del cuidador informal y su relación con variables moduladoras. Método: Se realizó una revisión bibliográfica en las bases de datos PubMed y PsychINFO sobre las consecuencias de la situación de cuidado en pacientes crónicos. Resultados: Diversos estudios sugieren que la condición de cuidador de un paciente oncológico pued…
Behavioral effects of different enriched environments in mice treated with the cholinergic agonist PNU-282987.
2013
Abstract Environmental enrichment is an experimental model in which rodents are housed in complex environments that favor lower levels of anxiety-like behavior. PNU-282987 (PNU) is a α7 nicotinic acetylcholine receptor agonist with beneficial effects on learning though its effects on anxiety are unclear. Our main aim was to carry out a study of its effects in NMRI ( n = 96) mice reared in different environments: environmental enrichment (EE), Marlau™ cages (MC) and standard environment (SE). After a 4-month period, mice received acute treatment of PNU (2.5, 5 and 10 mg/kg) and were evaluated in the elevated plus-maze (EPM) and hole-board (HB). In the EPM, both EE and MC reared mice showed …
The Mediational Role of Burden and Perceived Stress in Subjective Memory Complaints in Informal Cancer Caregivers.
2020
The role of informal caregiver of cancer patients is considered a situation of chronic stress that could have impact on cognitive functioning. Our aim was to evaluate differences in perceived stress, subjective memory complaints, self-esteem, and resilience between caregivers and non-caregivers, as well as the possible mediational role of burden in caregivers. The sample was composed of 60 participants divided into two groups: (1) Primary informal caregivers of a relative with cancer (CCG) (n = 34)
Enriched Environments for Rodents and their Interaction with Nicotine Administration
2012
An active lifestyle throughout the life cycle seems to delay cognitive aging and dementia and has also been evaluated as an intervention against addiction to cocaine and other drugs of abuse. In epidemiological studies with humans, it has proved difficult to separate the cognitive, social and physical components from other variables that influence lifestyle. Studies in animal models are useful for evaluating the impact of each of these factors and for uncovering the underlying mechanisms of the benefits of complex environments. Preclinical studies have employed the Environmental Enrichment paradigm (EE) which has been proposed as a preclinical model of positive life experiences in humans. E…
Behavioral impact of experience based on environmental enrichment: Influence of age and duration of exposure in male NMRI mice
2020
Prior studies have suggested that short periods of exposure to environmental enrichment (EE) in rodents induce physiological and behavioral effects. In the present study, our aim was to evaluate if the impact of experiences based on EE could be modulated by the age of onset and the developmental period of exposure. NMRI male mice (n = 64) were exposed to EE or standard environment (SE) and behavioral changes (anxiety, exploration, memory and social interaction) were evaluated. Groups compared were: (a) SE: exposure to SE on post-natal day (PND) 28 and lasting 6 months; (b) EE-6: exposure to EE on PND 28 and lasting 6 months; (c) EE-4: exposure to EE on PND 91 and lasting 4 months; (d) EE-2:…
Mindfulness y duelo: programa MADED, mindfulness para la aceptación del dolor, las emociones y el duelo
2020
Objective: to design a psychological intervention protocol for the accompaniment of pain and emotions in the grieving process based on attention and compassion. Method: mourners over 18 years of age, who have lost their family member at least 6 months ago, who are in phase 2 or 3 of the grieving process and who have no previous mental health problems, will be included. They will be evaluated after signing the informed consent, by means of: the Mindfulness Questionnaire, the Life Satisfaction Questionnaire, the Vitality Questionnaire, the Hospital Anxiety and Depression Scale, the Positive and Negative Affect Scale and the Complicated Grief Inventory. Descriptive statistics, Cohen’s t-test f…
