Artemether (AM) is one of the most effective antimalarial drugs. The elimination half-life of AM is very short, and it shows large interindividual variability in pharmacokinetic parameters. The aim of this study was to identify cytochrome P450 (P450) isozymes responsible for the demethylation of AM and to evaluate functional differences between 26 CYP2B6(More)
We investigated the effects of dynamic information on decoding facial expressions. A dynamic face entailed a change from a neutral to a full-blown expression, whereas a static face included only the full-blown expression. Sixty-eight participants were divided into two groups, the dynamic condition and the static condition. The facial stimuli expressed eight(More)
It has been demonstrated that stress conditions for babies such as a brief mother-infant separation cause the nasal skin temperature to drop. Changes in skin temperature may be taken as a representative sample of bodily reaction correlated with emotional changes. The purpose of this study is to investigate nasal skin temperature changes under loud noise(More)
The suggestion that dynamic facial expressions of emotion induce more evident facial mimicry than static ones remains controversial. We investigated this issue by recording EMG from the corrugator supercilii and zygomatic major. Dynamic and static facial expressions of anger and happiness were presented. Dynamic presentations of angry expressions induced(More)
Many studies have indicated that recognition of facial expression is geometrically represented in terms of two underlying bipolar dimensions, pleasure-displeasure and the intensity of arousal. A psychological space defined by these two dimensions has been found under particular conditions using prototype faces: however, the question arises whether this(More)
Transparency perception is recognized as one of the important phenomena to understand the computational mechanism of early visual system. Transparency perception indicates that a simple theory reconstructing a single-valued field of a visual attribute, such as an optical-flow field, cannot model the neural mechanism for the human visual system and raises a(More)
Observers in Canada (n = 50), Greece (n = 38), and Japan (n = 50) were shown seven of Matsumoto and Ekman's (1988) photographs reported to show universally recognizable facial expressions of basic emotions. Observers were asked to name the emotion expressed with any single emotion label they wanted. Across cultures., recognition (percentage of observers(More)
In this study, we investigated the effect of an indoor plant on task performance and on mood. Three room arrangements were used as independent variables: a room with (1) a plant, or (2) a magazine rack with magazines placed in front of the participants, or (3) a room with neither of these objects. Undergraduate students (M= 35, F= 55) performed a task of(More)
This study investigated whether the underlying structure of responses to facial expressions of emotion would emerge when the exposure time was increased. 25 participants judged facial photographs presented for varying durations of exposure, ranging from 4 msec. to 64 msec. in 4-msec. steps. A dual scaling method was carried out to analyze possible response(More)
BACKGROUND The relationships between facial mimicry and subsequent psychological processes remain unclear. We hypothesized that the congruent facial muscle activity would elicit emotional experiences and that the experienced emotion would induce emotion recognition. METHODOLOGY/PRINCIPAL FINDINGS To test this hypothesis, we re-analyzed data collected in(More)
