It is difficult to design the Virtual Reality (VR) Environment which controls VR sickness and promotes presence. This is because the relationship between the user's susceptibility to VR sickness and a sense of presence, determined by velocity and visual angle of the visual information, involves a trade-off between the two. Then we propose the optimal value search system which computes efficient...

Objective: Neuroimmune factors contribute on the pathogenesis of sickness behaviors. Nigella sativa (NS) has anti-inflammatory, anti-anxiety and anti-depressive effects. In the present study, the effect of NS hydro-alcoholic extract on sickness behavior induced by lipopolysaccharide (LPS) was investigated. Materials and Methods: The rats were divided into five groups (n=10 in each): (1) control...

BACKGROUND Altitude illness results from hypobaric hypoxia at altitudes higher than 2500 meters above sea level. To determine whether vital signs can be used as predictors for severe acute mountain sickness, we carried out a prospective observational study. METHODS A cohort of 90 individuals (male/female ratio: 2; age: 13 - 65 years) in a mountain hotel's clinic at 3450 meters in Iran were st...

PURPOSE Breast cancer diagnosis and treatment are associated with increased inflammatory activity, which can induce sickness symptoms. We examined whether emotional acceptance moderates the association between proinflammatory cytokines and self-reported sickness symptoms in women recently diagnosed with breast cancer. METHODS Women (N=136) diagnosed with stage 0-III breast cancer within the p...

INTRODUCTION Zero-G parabolic flight reproduces the weightlessness of space for short periods. However, motion sickness may affect some fliers. The aim was to assess the extent of this problem and to find possible predictors and modifying factors. METHODS Airbus zero-G flights consist of 31 parabolas performed in blocks. Each parabola consisted of 20 s of 0 g sandwiched by 20 s of hypergravit...

BACKGROUND Sickness absence is an important economic problem, because of high costs and lost productivity. Determining factors associated with increased risk of sickness absence may lead to the development of preventive measures. AIMS To determine whether self-report questionnaires can identify those employees at risk of sickness absence METHODS Prospective study of 238 healthy administrati...

BACKGROUND Obesity is an increasing public health problem. A small number of studies have examined the relationship between obesity and sickness absence, with mixed results, particularly regarding short-term sickness absence. AIMS To determine if obesity is associated with short- and long-term sickness absence and to investigate the mechanisms that may underlie any association. METHODS Cros...

On 6th July 1899, Mrs R., a tall, fairly stout and healthy-looking young woman, consulted me about an abdominal swelling which she had first noticed six months previously, and which had grown steadily in size. She gave the following history:?Her mother died at the age of 61, and one of her sisters died at the age of 35, both of them, she understood, of ovarian tumours. Neither of them was opera...

Astigmatism is a very common refractive error in infants. The etiology of astigmatism is poorly understood although it may involve pregnant environmental factors. The aim of this study was to examine the association between pregnant nutrition and the risk of infant astigmatism in twins. Total 28 pairs of twins (11 monozygotic and 17 dizygotic), whose mothers had been involved in this study sinc...
