Few studies have been carried out to examine the relation between postural stability and subjective reports or feelings of motion sickness. Two views seem to exist on the relation between immersion in a virtual reality (VR) environment and subjective feelings of motion sickness. One predicts that the immersion induces both postural instability and motion sickness. Another view is that preimmers...

BACKGROUND Exposure to shift work has been associated with negative health consequences, although the association between shift work and sickness absence remains unclear. The aim of this study is to investigate associations between cumulative exposure to shift work and sickness absence among ground staff employees of an airline company. METHODS This study used data from the MORE (Monitoring O...

The radioprotective activity of Nigella sativa extract (NSE) was ascertained by administering mice orally with 25, 50, 100, 150, 200, 400 or 500 mg/kg b. wt. of NSE, once daily for five consecutive days prior to 10 Gy γ-irradiation. One hour after the last administration of NSE on fifth day, the animals were whole body exposed to 10 Gy radiation. The exposure of animals to 10 Gy irradiation res...

Serum sickness is an immune-complex-mediated systemic illness that can occur after treatment with monoclonal or polyclonal antibodies such as Rituxan (Rituximab) or antithymocyte globulin (Thymoglobulin), respectively. Since Rituximab is now being used as an adjuvant treatment for acute humoral rejection and its prevalence to cause serum sickness is comparable to Thymoglobulin-associated serum ...

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 Observation of physiological changes during motion sickness is required to quantify the degree of sickness. The review of the literature does not show unifying results. An objective symptom of motion sickness is facial pallor. It reflects changes in skin microcirculation which have not been measured so far. METHODS Eleven healthy volunteers susceptible to motion sickness were subje...

The A-bomb blast released a huge amount of energy: thermal radiation (35%), blast energy (50%), and nuclear radiation (15%). Of the 15%, 5% was initial radiation released within 30 s and 10% was residual radiation, the majority of which was fallout. Exposure doses of hibakusha (A-bomb survivors) were estimated solely on the basis of the initial radiation. The effects of the residual radiation o...

Virtual environment induces simulator sickness effect for some users. The purpose of this research is to compare the simulation sickness relative with parallax affect in one-screen and three-screen HoloStage system, measured by Simulation Sickness Questionnaire (SSQ). The results show the subjects tested in three-screen has less sickness than one-screen and effect from the Oculomotor (O) more t...

INTRODUCTION Increased sickness absence in recent years has been a trouble making issue in industrial society. Identify the causes of sickness absence and its influencing factors, is an important step to control and reduce its associated complications and costs. The aim of this study was to evaluate main factors associated with the incidence of sickness absence. PROCEDURE In 2012, a cross-sec...

Mounting a sickness response is an energetically expensive task and requires precise balancing of energy allocation to ensure pathogen clearance while avoiding compromising energy reserves. Sickness intensity has previously been shown to be modulated by food restriction, body mass, and hormonal signals of energy. In the current study, we tested the hypothesis that sickness intensity is modulate...
