There have been several studies which have tried to clarify the neural mechanisms of fatigue sensation; however fatigue sensation has multiple aspects. We hypothesized that past experience related to fatigue sensation is an important factor which contributes to future formation of fatigue sensation through the transfer to memories that are located within specific brain structures. Therefore, we...

OBJECTIVE To measure the levels of fatigue in the general population, and to examine how disease and sociodemographic factors influence fatigue. DESIGN Cross sectional questionnaire study in the Danish general population. SUBJECTS A random, age stratified sample of 1608 people aged 20-77 with an equal gender distribution (response rate 67%). MAIN OUTCOME MEASURES Five fatigue scales from ...

when stretcher came to unit and i was put in my bed, nursing personnel of surgical ward said to me hello. i had seen their face from yesterday night when they were transferring patients from emergency ward to this unit.  in that time, i had the role of emergency ward assistant manager. today, i am a weak patient that even is unable for smallest movement. cause of my admission to hospital is mus...

background: fatigue is a common side effect in cancer patients undergoing radiation therapy (rt). radiation-induced fatigue affects the quality of life, but there is no definitive treatment option. in this study, the weight-loaded forced swim test was performed to assess the effect of coenzyme q10 (coq10) on radiation-induced fatigue. materials and methods: a total of 60 rats were divided rando...

The nature of fatigue is very complex and involves physiological, psychological and social phenomena at the same time, and the mechanisms leading to occurrence and severity of fatigue are still poorly understood. The condition of chronic inflammation associated with psoriatic arthritis can be regarded as a potential factor affecting development of fatigue. Only a few studies so far have focused...

In the present work, we investigate the effect of "fatigue" on the fatigue behavior and atomic structure of Zr-based BMGs. Fatigue experiments on the failed-by-fatigue samples indicate that the remnants generally have similar or longer fatigue life than the as-cast samples. Meanwhile, the pair-distribution-function (PDF) analysis of the as-cast and post-fatigue samples showed very small changes...

original article   mental fatigue (mf) is considered as a contributor factor in incident, even catastrophic one. electroencephalography measurement has been the most acceptable method to assess mf by neurologists. however, this method could be hardly feasible in real work setting. flicker fusion device, by contrast, is more usable at work setting. the purpose of this study was to compare the cr...

the crankshaft is one of the most critically loaded components as it experiences cyclic loads in the form of bending and torsion during its service life. its failure will cause serious damage to the engine so it’s important at the time of design to verify fatigue strength. more challenges in crankshaft design due to increasing vehicle payloads, lower weight requirement, higher efficiency and lo...

objective: optimal dentin bonding is not always obtained in clinical practice due to func-tional forces. these forces may provide stresses throughout the tooth and restorative sys-tem, which in turn may affect the adhesive bond. this experimental study evaluated the effect of load cycling on bond strength of self-etch systems. materials and methods: one third of the coronal portions of 48 intac...
