..We examined the effects of a human-type communication robot on cognitive function in elderly women living alone...

..Impaired high-level information processing such as that required for conflict-controlling selective attention in the central nervous system may be a characteristic feature of moderate- to long-term fatigue...

..However, there have been no reports examining the effects of a pellet stove on recovery from mental fatigue. The purpose of this study was to examine the effects of a pellet stove on recovery from mental fatigue...

..Thus, in order to clarify the mechanisms underlying mental fatigue, we examined the association between mental fatigue and autonomic functions...

..Fatigue is a common symptom in both sick and healthy people. We examined autonomic nervous alterations associated with fatigue to clarify the mechanisms underlying fatigue...

..The reliability (alpha) and construct validity of the Japanese version of the scale among healthy students in Japan were satisfactory for research studies among healthy school students...

..The results suggest that stress and the coping style are correlated with fatigue in medical students...

..We tested the hypothesis that daidzein may reduce myocardial damage by both inhibiting the release of cytokines and limiting the nuclear translocation of NF-kappaB...

..Fatigue is a common symptom in modern society. In order to clarify the mechanisms underlying fatigue, we examined the association between central nervous system fatigue and autonomic nerve activity...

..In addition, this theory will likely contribute to a better understanding of the pathophysiology of chronic fatigue syndrome...

..The temperament dimension of Harm Avoidance and the character dimension of Self-directedness were both associated with Fatigue in medical students...

..However, in our daily lives, combined fatigue, which is the combination of physical and mental fatigue, is most often experienced. In this study, the effects of (-)-epigallocatechin gallate (EGCg) on combined fatigue were assessed...

..These results suggest that the ipsilateral sensorimotor and prefrontal areas are brain regions associated with compensation mechanisms to support motor output under the condition of physical fatigue...

..To determine whether abnormal EKG findings could be predictive factors for death after a stroke event...

..Although the neural mechanism of chronic fatigue syndrome has been investigated by a number of researchers, it remains poorly understood...

..We identified neural evidence of the central inhibition and showed that the visual feedback system is involved in the central mechanism regulating motor output...

..In this study, the relationships between personality traits and intrinsic academic motivation were examined in medical students...

..Administration of ascorbic acid did not change in MV from the 30-minute to the 210-minute test on males or females. These results suggest that daily administration of crocetin may attenuate physical fatigue in men...

..These results suggest that it is desirable to consider social support, quality of sleep, and effort-reward imbalance when managing fatigue in school children...

..We examined the effects of administering two different candidate antifatigue substances, caffeine and D-ribose, on mental fatigue...

..The daily level of fatigue was related to VEF intensity after the acute mental fatigue loads. Our findings provide new perspectives to evaluate our daily level of fatigue as well as to clarify the neural mechanisms underlying it...

..We aimed to identify changes in amino acid levels in the plasma, skeletal muscle, liver, and brain in an animal model of complex fatigue...

..These results indicate that TTFD exerts anti-fatigue effects by improving energy metabolism during physical fatigue...

..To confirm fatigue-related biochemical alterations, we measured various parameters just before and after relaxation and fatigue-inducing mental or physical sessions...

..However, no studies have identified cognitive predictors of fatigue. Therefore, we attempted to determine independent cognitive predictors of fatigue in these students...

..This study examined the effects of coenzyme Q10 administration on physical fatigue...

..Since grade-dependent development of cognitive functions also influences academic performance by these students, we examined whether cognitive functions are related to the prevalence of decrease in intrinsic academic motivation...

..However, the changes in cognitive functions during this transitional period have rarely been studied...

..Since grade-dependent development of cognitive functions also influences academic performance, we attempted to determine whether cognitive functions were associated with the prevalence of fatigue...

..81). With our protocol, when anesthesia was started 40 min after the FDG injection, the glucose metabolism was almost the same as that in the conscious rat brain...

..In contrast, when 0.5 mM 4-CIN was applied to the normal glucose solution, [18F]FDG uptake rate increased. These results suggest that exogenous and endogenous lactate can substitute for glucose in the brain...

..We conclude that the putamen is critical for motivation in different domains and the extent of activity of the putamen may be pivotal to the motivation that drives academic achievement and thus academic successes...

..However, there have been few reports examining the effects of bathing on recovery from mental fatigue. The purpose of this study was to examine the effects of mild-stream bathing on recovery from mental fatigue...

..These results strongly demonstrated the value of measuring glucose utilization in the brains of conscious rats...

..Although this level of increase in the plasma concentration of ALA may not induce fatigue, increase in plasma and urinary ALA levels can be biomarkers of fatigue...

..The present study also suggests that prolonged hyperactivation of endocrine cells could lead to disorder of secretion mechanisms and eventual degeneration...

..The PCC is the brain region activated by viewing others expressing fatigue, suggesting existence of the shared neural substrates of felt and observed fatigue...

..These data suggest that improvement of glucose uptake and increased serotonergic and dopaminergic neuronal activities are associated with recovery from central fatigue...

..While no association was observed between the scores of PFS-J and Body Mass Index, the scores were higher in women than in men. Characteristics of the appetitive motives in Japan might be different from those in western countries...

..We examined the effects of Applephenon and ascorbic acid administration on physical fatigue...

..Our data suggest that decreased glucose uptake and insufficient serotonin and dopamine turnover introduced by deprivation of rest were correlated with central fatigue...

..These data suggest that decreased energy utilization in the brain is a feature of fatigue...
