Fatigue is an indispensable bioalarm to avoid exhaustive state caused by overwork or stresses. It is necessary to elucidate the neural mechanism of fatigue sensation for managing fatigue properly. We performed H(2) ( 15)O positron emission tomography scans to indicate neural activations while subjects were performing 35-min fatigue-inducing task trials(More)
BACKGROUND Numerous associations between brain-reactive antibodies and neurological or psychiatric symptoms have been proposed. Serum autoantibody against the muscarinic cholinergic receptor (mAChR) was increased in some patients with chronic fatigue syndrome (CFS) or psychiatric disease. We examined whether serum autoantibody against mAChR affected the(More)
BACKGROUND Using the Temperament and Character Inventory (TCI), we examined personality characteristics in patients with chronic fatigue syndrome (CFS) compared with healthy control subjects, and CFS patients with and without psychiatric diseases. There have been no previous reports assessing personality in CFS patients using the TCI. METHODS A total of(More)
AIMS 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. MAIN METHODS The study group consisted of 20 healthy subjects. They performed the 2-back test for 30 min to induce fatigue. Just before and after the(More)
AIMS Chronic fatigue syndrome patients often have comorbid psychiatric disorders such as major depressive disorders and anxiety disorders. However, the outcomes of chronic fatigue syndrome and the comorbid psychiatric disorders and the interactions between them are unknown. Therefore, a two-year prospective follow-up study was carried out on chronic fatigue(More)
Fatigue is defined as a condition or phenomenon of decreased ability and efficiency of mental and/or physical activities, caused by excessive mental or physical activities, diseases, or syndromes. It is often accompanied by a peculiar sense of discomfort, a desire to rest, and reduced motivation, referred to as fatigue sensation. Acute fatigue is a normal(More)
Chronic fatigue syndrome (CFS) is a persistent and unexplained pathological state characterized by exertional and severely debilitating fatigue, with/without infectious or neuropsychiatric symptoms, lasting at least 6 consecutive months. Its pathogenesis remains incompletely understood. Here, we performed comprehensive metabolomic analyses of 133 plasma(More)

The deformities of the lip and nose in cleft lip patients are intimately inter-related and their repair should not be independent procedures. The reconstruction should be dynamic, taking into account the different functions of the groups of the perioral musculature. For the lip repair, attenuation of the musculus nasalis of the sound side and the formation(More)
A case is reported of Apert's syndrome with severe bilateral balloonings of the temporal region in addition to other typical craniofacial deformities. He had had three previous strip craniectomies. His mentality and intelligence were normal. In order to improve his deformities, the following steps were carried out: 1. 1.5 cm frontal advancement with(More)
