Crucial role for Nox2 and sleep deprivation in aircraft noise-induced vascular and cerebral oxidative stress, inflammation, and gene regulation
2018
Abstract Aims Aircraft noise causes endothelial dysfunction, oxidative stress, and inflammation. Transportation noise increases the incidence of coronary artery disease, hypertension, and stroke. The underlying mechanisms are not well understood. Herein, we investigated effects of phagocyte-type NADPH oxidase (Nox2) knockout and different noise protocols (around-the-clock, sleep/awake phase noise) on vascular and cerebral complications in mice. Methods and results C57BL/6j and Nox2 −/− (gp91phox −/−) mice were exposed to aircraft noise (maximum sound level of 85 dB(A), average sound pressure level of 72 dB(A)) around-the-clock or during sleep/awake phases for 1, 2, and 4 days. Adverse effec…
The sensory and nutritional experience of parents guide offsprings' feeding behavior
2016
Le comportement alimentaire est régulé par des facteurs physiologiques intrinsèques et est largement influencé par l’environnement culturel. Une prise alimentaire excessive et un mode de vie trop sédentaire sont les principales raisons de l’épidémie mondiale d’obésité. Si l’influence du contexte familial sur les habitudes alimentaires ne fait aucun doute, le fait que l’état nutritionnel, métabolique et hormonal des parents avant la conception, puis de la mère pendant la gestation et l’allaitement puisse influencer le comportement alimentaire futur de l’enfant est un concept novateur qui ouvre la voie à des mesures de prévention. Au cours des dernières décennies, des travaux sur des cohortes…
Type of surgery is associated with pain and walking difficulties among older people with previous hip fracture
2015
Aim The aim was to assess the level of lower body pain among people with previous femoral neck fracture, and whether the type of surgery was associated with pain and physical function a mean of 2 years after surgery. Methods The study included 115 community-dwelling older adults aged 60 years and older with previous femoral neck fracture, and 31 reference subjects without previous lower limb injuries. A total of 30 patients had internal fixation surgery, 70 had hemiarthroplasty and 15 had total hip replacement. All patients had surgery in the same hospital and received typical inpatient rehabilitation. From 1.6 months to 7.5 years after the fracture, the patients underwent examination inclu…
Uses of change-over designs and repeated measurements in sensory and consumer studies
1993
Abstract The paper illustrates two statistical methods, the design and analysis of sensory experiments taking into account the effects of serving order and previously assessed treatment and the analysis of experiments with time repeated measurements. Change-over design experiments balance both presentation order and carry-over effects. The proper analysis of variance allows the testing of these effects and the estimation of product means adjusted for carry-over effect. Repeated measurements occur when groups are being compared over time. Either a corrected split-plot or a multivariate analysis of variance (MANOVA) with measurements at different times forming the variable should be adopted t…
Adolescents’ physical, emotional and social balance: a concept of pedagogical assistance and social rehabilitation
2017
The paper summarizes research findings from two scientific fields (pedagogical and medical), which confirm that there are substantial discrepancies in an individuals’ biological, psychological and social development in the period of adolescence leading to a developmental imbalance mainly related to learning. The article offers for discussion a possible conceptual approach and practice-grounded changes of pedagogical provisions to improve teenagers’ physical, psycho-emotional balance and social rehabilitation culminating in overall well-being.
Enhancement of Anticipatory Postural Adjustments by Virtual Reality in Older Adults with Cognitive and Motor Deficits: A Randomised Trial.
2021
Background: Postural activities involved in balance control integrate the anticipatory postural adjustments (APA) that stabilize balance and posture, facilitating arm movements and walking initiation and allowing an optimal coordination between posture and movement. Several studies reported the significant benefits of virtual reality (VR) exercises in frail older adults to decrease the anxiety of falling and to induce improvements in behavioural and cognitive abilities in rehabilitation processes. The aim of this study was thus to test the efficiency of a VR system on the enhancement of the APA period, compared to the use of a Nintendo Wii system. Methods: Frail older adults (n = 37) were i…
Rate of concurrent augmented auditory feedback in postural control learning in adolescents
2020
Introduction: The main objective of this study was to determine the rate of auditory concurrent feedback that best enhanced the learning of a continuous postural task in adolescents. Material and methods: A sample of thirty adolescents (13 to 14-years old) was used, who were assigned to three groups: i) control group (CG); ii) 100% auditory feedback group and iii) 67% auditory feedback group. The subjects performed a pre-test, practice, post-test and a retention (24 hours after the practice). In the postural control task subjects were instructed to remain on a seesaw (unstable in anteroposterior position) and keeping it as level as possible. Results: The results demonstrated that concurrent…
Balance Perturbations as a Measurement Tool for Trunk Impairment in Cross-Country Sit Skiing
2018
In cross-country sit-skiing, the trunk plays a crucial role in propulsion generation and balance maintenance. Trunk stability is evaluated by automatic responses to unpredictable perturbations; however, electromyography is challenging. The aim of this study was to identify a measure to group sit-skiers according to their ability to control the trunk. Seated in their competitive sit-ski, 10 male and 5 female Paralympic sit-skiers received 6 forward and 6 backward unpredictable perturbations in random order. k-means clustered trunk position at rest, delay to invert the trunk motion, and trunk range of motion significantly into 2 groups. In conclusion, unpredictable perturbations might quantif…
Long-term home-based physiotherapy for persons with signs of frailty–RCT (NCT02305433)
2018
Introduction/Background Frailty is a multidimensional condition, which can lead to disability. To postpone long-term care, one alternative is home-based physiotherapy. We study the effects of a 12-month home-based physiotherapy program on functional capacity, and applying successive 12-month register follow-up, on the use and costs of social and health care services, and on the duration of living at home during 24 months (the primary outcome). Here we report about feasibility of the intervention and baseline characteristics. Material and method Three hundred home-dwelling persons (>65 y) with signs of frailty were recruited by September, 2016. Frailty was screened by Morley's FRAIL question…
