Problematic internet use prior to and during the COVID-19 pandemic

2021

The health and socio-economic challenges arising from the COVID-19 pandemic have led to greater reliance on the internet to meet basic needs and responsibilities. Greater engagement in online activities may have negative mental and physical health consequences for some vulnerable individuals, particularly under mandatory self-isolation or ‘lockdown’ conditions. The present study investigated whether changes in levels of involvement in online activities during the COVID-19 pandemic (i.e., watching TV series,online sexual activities, video games, social networks, gambling, online shopping, and instant messaging) were associated with problematic internet use, as well as whether certain psychol…

Sports and Community Well-Being

2017

This chapter explores the relationship between sports and community well-being, taking into account factors such as social bonds, social and cultural integration, health, improved quality of life, and the enhancement of personal and community well-being. Well-being is a concept with a long history and development. Originally used in the field of philosophy, it then spread to psychology. Community well-being is a relatively recent, little-explored term, which builds on the concepts of well-being and quality of life. This chapter provides a theoretical assessment based on the concepts of well-being, community well-being, and sports, distinguishing the latter from mere physical activity. Final…

A model study for the progressive disruption of CA1 firing properties during Alzheimer’s disease

2011

Several independent studies show that β-Amyloid (Aβ) peptides accumulation, one of the characteristic hallmark of Alzheimer’s Disease (AD), can affect the normal neuronal activity in different ways causing an increase or a decrease in neuronal membrane excitability. For example, experimental evidence for a negative impact on neuronal membrane in animal models of AD has been obtained in dual patch recordings in rat hippocampal tissue slices, in which Aβ blocked K channels in pyramidal cell dendrites, causing an increase in dendritic membrane excitability. The resulting increased Ca2+ influx and excitoxicity may lead to dendritic degeneration. However, further experimental evidence suggests t…

Can specific pre-workout meals reduce bone resorption in young gymnasts?

2021

The pre-adolescence in woman is a key stage to obtain adequate bone mineral content and to decrease the risk of osteoporosis in adulthood. Exercise and adequate nutrition can influence the bone growth process. The aim of this paper was to verify if a different pre-exercise meal can change exercise-induced bone resorption in female child artistic gymnasts. Twenty-eight preadolescent female were requited for this study. Training was preceded by high-carbohydrate meal (HCM; 300 kcal, 88% carbohydrates, 9% protein, 3% fat) or high protein meal (HPM; 300 kcal, 55% carbohydrates, 31% protein, 13% fat) ninety minutes before the start of the training session. Bone resorption biomarker, C-terminal t…

Heat Shock Proteins in Multiple Sclerosis Pathogenesis: Friend or Foe?

2015

Multiple Sclerosis is a complex chronic inflammatory, neurodegenerative disease conditioned by genetic, epigenetic and environmental factors. Main pathological features of MS include areas of focal demyelination of white matter characterized by gliosis, neuron and oligodendrocyte loss. Neurodegenerative as well as immune-mediated processes play a role in the pathogenesis of this disease. One of these immunogenic factors could be represented by the heat shock proteins. HSP exhibit cytoprotective and cytostimulatory effects due to their molecular chaperones role, in many brain model misfolding diseases such as Alzheimer’s and Parkinson’s diseases, whereas still no unambiguous results have bee…

Health-related correlates of psychological well-being among girls and boys 6-8 years of age: The Physical Activity and Nutrition in Children study

2018

AIM Due to limited knowledge on the differences in the correlates of psychological well-being (PSWB) between girls and boys, we compared the correlates of PSWB between primary school girls and boys. METHODS A population sample of 412 children participated in the Physical Activity and Nutrition in Children study. Parents completed a questionnaire that included 19 questions on the components of PSWB, and a PSWB score was computed. We assessed correlates of PSWB, including physical activity, sedentary behaviour, cardiorespiratory fitness, diet quality, body fat content, sleep duration, sleep disordered breathing, prevalent diseases and parental characteristics. We used logistic regression to a…

The Diffusion of the Activity-Based Costing Method: A Comparison between France and China

2011

In France, like in the USA, the Activity-based Costing method (ABC) was considered as a remedy for the crisis of management accounting. Now, the level of diffusion in France is as important as in the Anglo-Saxon countries. Not surprisingly, the ABC method is more developed in western countries than in China. Chinese scholars began to do researches on ABC in the 1990s and at the beginnings of the 21st century, we can observe some ABC implementations in Chinese manufacturing enterprises and then in the service industries. But, we can also find a similarity between the Chinese and French situations. In France, we have observed some resistances to the Anglo-Saxon way of manage firms and at the …
