Estilos de ingesta, ver la televisión y picar comida en niños preadolescentes
2012
Introduction: Television viewing is considered to be a risk factor for overweight in children because of its association with reduced physical activity and increased calorie intake. Objective: The aim of the present study is to examine whether eating styles affect the relationship between television viewing (TV-viewing) and snacking. Method: In a sample of 962 pre-adolescents, selfreported television viewing and snacking were assessed in relation to dietary restraint, external eating and emotional eating, as measured with the child version of the Dutch Eating Behavior Questionnaire. With regression analyses we assessed the possible moderating role of emotional, external and restrained eatin…
Anti-inflammatory and antioxidant effects of muscarinic acetylcholine receptor (mAChR) activation in the rat hippocampus
2019
AbstractRecently we found that acute treatment with Oxotremorine (Oxo), a non-selective mAChRs agonist, up-regulates heat shock proteins and activates their transcription factor heat shock factor 1 in the rat hippocampus. Here we aimed to investigate: a) if acute treatment with Oxo may regulate pro-inflammatory or anti-inflammatory cytokines and oxidative stress in the rat hippocampus; b) if chronic restraint stress (CRS) induces inflammatory or oxidative alterations in the hippocampus and whether such alterations may be affected by chronic treatment with Oxo. In the acute experiment, rats were injected with single dose of Oxo (0.4 mg/kg) and sacrificed at 24 h, 48 h and 72 h. In the CRS ex…
Exercise promotes IL-6 release from legs in older men with minor response to unilateral immobilization
2015
Physical inactivity is a major contributor to low-grade systemic inflammation. Most of the studies characterizing interleukin-6 (IL-6) and tumour necrosis factor-α (TNF-α) release from exercising legs have been done in young, healthy men, but studies on inactivity in older people are lacking. The impact of 14 days of one-leg immobilization (IM) on IL-6 and TNF-α release during exercise in comparison to the contralateral control (CON) leg was investigated. Fifteen healthy men (age 68.1 ± 1.1 year (mean ± SEM); BMI 27.0 ± 0.4 kg·m(2); VO2max 33.3 ± 1.6 ml·kg(‒1)·min(‒1)) performed 45 min of two-leg dynamic knee extensor exercise at 19.5 ± 0.9 W. Arterial and femoral venous blood samples from …
Parental Perceptions of the Use of Coercive Measures on Children with Developmental Disabilities
2016
Background Children with developmental disabilities who exhibit challenging behaviour are potentially subject to the use of coercive interventions. The aim of the study was to investigate the prevalence of the use of coercive measures by authorities, according to parents’ reports. Materials and Methods A postal survey was distributed, as a total population study, to 946 Finnish parents of children with developmental disabilities, between the ages of 5 and 15, and who were entitled to the highest disability allowance. Results Of the respondents, 54 (22%) answered ‘yes’ when asked whether their child had been subjected to coercive procedures by authorities. The parents had seldom approved the…
Novel sequential stress model for functional dyspepsia: Efficacy of the herbal preparation STW5
2015
Abstract Background Many screening procedures for agents with potential usefulness in functional dyspepsia (FD) rely on animals exposed to stress early in life (neonatal maternal separation, NMS) or in adulthood (restraint stress, RS). Purpose Since many clinical cases of FD have been associated with stress in early life followed by stress in adulthood, a sequential model simulating the clinical situation is described. To explore the validity of the model, the efficacy of STW5, a multicomponent herbal preparation of proven usefulness in FD, was tested. Study design/methods A sequential stress model established where rats are exposed to NMS after birth followed later by RS in adulthood. Stre…
Brain-Derived Neurotrophic Factor But Not Forced Arm Use Improves Long-Term Outcome After Photothrombotic Stroke and Transiently Upregulates Binding …
2008
Background and Purpose— Both application of neurotrophic factors like brain-derived neurotrophic factor (BDNF) and constraint-induced movement therapy like forced arm use have been shown to potentially improve outcome after stroke. The aim of the present study was to check whether postischemic long-term outcome correlates to specific modifications in the abundance of various neurotransmitter receptors. Methods— Adult male Wistar rats were subjected to photothrombotic ischemia and assigned to various treatment groups (n=5 each) with end points at 3 and 6 weeks: (1) ischemic control (saline); (2) BDNF (ischemia, 20 μg BDNF); (3) forced arm use (ischemia, saline, and ipsilateral plaster cast …
Influence of trait anxiety on the effects of acute stress on learning and retention of the passive avoidance task in male and female mice
2013
The influence of anxiety on the effects of acute stress for the acquisition and retention of passive avoidance conditioned task was evaluated in male and female mice. Animals were categorized as high-, medium-, and low-anxiety according to their performance in the elevated plus-maze test. Subsequently, half of the mice in each group were exposed to an acute stressor and assayed in an aversive conditioning test two days later. Exposure to restraint stress before inhibitory avoidance conditioning had a differential impact on the conditioned response of males and females according to their trait anxiety. The acute stressor significantly altered the conditioned response of mice with a high-anxi…
c-fos expression, behavioural, endocrine and autonomic responses to acute social stress in male rats after chronic restraint: modulation by serotonin
2000
The effects in male rats of serotonin depletion (using the neurotoxin 5,7-dihydroxytryptamine) on the cross-sensitization of an acute social stress (defeat by a larger resident male) by previous repeated restraint stress (10 days, 60 min per day) was studied. Previous restraint increased freezing responses during social defeat in sham-operated rats, but this was not observed in those with depleted serotonin (83% or more in different regions of the brain). In contrast, neither heart rate (tachycardia) nor core temperature responses (hyperthermia) were accentuated in previously restrained rats (i.e. neither showed heterotypical sensitization), and neither adapted to repeated restraint (there …
Impaired hippocampal neuroligin-2 function by chronic stress or synthetic peptide treatment is linked to social deficits and increased aggression.
2014
Neuroligins (NLGNs) are cell adhesion molecules that are important for proper synaptic formation and functioning, and are critical regulators of the balance between neural excitation/inhibition (E/I). Mutations in NLGNs have been linked to psychiatric disorders in humans involving social dysfunction and are related to similar abnormalities in animal models. Chronic stress increases the likelihood for affective disorders and has been shown to induce changes in neural structure and function in different brain regions, with the hippocampus being highly vulnerable to stress. Previous studies have shown evidence of chronic stress-induced changes in the neural E/I balance in the hippocampus. Ther…
Effectiveness of constraint-induced movement therapy on activity and participation after stroke: a systematic review and meta-analysis of randomized …
2011
Objective: To examine the effect of constraint-induced movement therapy and modified constraint-induced movement therapy on activity and participation of patients with stroke (i.e. the effect of different treatment durations and frequency) by reviewing the results of randomized controlled trials. Data sources: A systematic literature search was conducted in MEDLINE, CINAHL, EMBASE, PEDro, OTSeeker, CENTRAL and by manual search. Review methods: Randomized controlled trials for patients over 18 years old with stroke and published in Finnish, Swedish, English or German were included. Studies were collected up to the first week in May 2011. The evidence was high, moderate, low or no evidence a…
