Termos novos, tais como stress oxidativo, produtos anti-oxidantes ou risco pro-oxidante, estão se tornando mais comuns, e o aumento no número de conferências científicas internacionais e a publicação de milhares de artigos científicos é uma indicação do crescente interesse no assunto. O exemplo mais conhecido é o Paradoxo Francês, baseado na aparente compatibilidade de uma dieta rica em gordura...

Introduction :Down syndrome is the most prevalent abnormal chromosomal disorder in human and the best known genetic cause of mental retardation which lays the foundations for physical and congenital defects and abnormalities. Abnormal behaviors of children with Down syndrome impair their mother's self-efficacy. The present study was conducted to investigate the effect of reality therapy on gene...

Some clinicians have suggested using virtual reality environments to deliver psychological interventions to treat anxiety disorders. However, given a significant body of work on cybersickness symptoms which may arise in virtual environments - especially those involving simulated motion - we tested (a) whether being exposed to a virtual reality environment alone causes anxiety to increase, and (...

People experience different levels of presence (e.g. Krijn et al., 2004; Walshe, Lewis, Kim, O'Sullivan, & Wiederhold, 2003), and different levels of cybersickness (Sharples, Cobb, Moody, & Wilson, 2008) even though they are immersed in the same virtual environment setting. In the current study, we raised the question how differences in individual characteristics might relate to differences in ...

Virtual Reality (VR) is successfully employed for a real huge variety of applications because it can furnish major improvement and can be really effective in fields such as engineering, medicine, design, architecture and construction, education and training, arts, entertainment, business, communication, marketing, military, exploration, and so on. Therefore great efforts have been paid over tim...

One possible alternative to standard in vivo exposure may be virtual reality exposure. Virtual reality integrates real-time computer graphics, body tracking devices, visual displays, and other sensory input devices to immerse a participant in a computer-generated virtual environment. Virtual reality exposure (VRE) is potentially an efficient and cost-effective treatment of anxiety disorders. VR...

Objective. Chronic pain conditions such as phantom limb pain and complex regional pain syndrome are difficult to treat, and traditional pharmacological treatment and invasive neural block are not always effective. Plasticity in the central nervous system occurs in these conditions and may be associated with pain. Mirror visual feedback therapy aims to restore normal cortical organization and is...
