A short (S) variant, compared to a long (L) variant, of the promoter region of the serotonin transporter gene-linked polymorphic region (5HTTLPR) has been related to emotional hyper-reactivity. We tested whether the 5HTTLPR could modulate acute stress responses in the brain and, the cardiovascular and neuroendocrine systems. Ten Japanese male participants carrying double copies of the S alleles and 10 Japanese males carrying S and L alleles conducted a mental arithmetic task, and their regional cerebral blood flow by <SU15</SUO positron emission tomography and cardiovascular and neuroendocrine parameters were measured. During the acute stress task, the participants with the SS alleles showed stronger reactivity in blood pressure and secretion of epinephrine, compared to the participants with the SL and LL alleles. Furthermore, the SS carriers showed greater activation in stress-related brain regions such as the hypothalamus, cerebellum, midbrain, and pulvinar compared to the SL and LL carriers during the acute stress task. The present findings indicated that the S allele of the 5HTTLPR is associated with greater brain and physiological reactivity to acute stress in Japanese men.</.

Two types of focusing strategies on body information have been proposed. One is maladaptive focusing, involving suppressing one's own body sensations and evaluating one's own performance, and the other is adaptive, involving focusing on one's own body sensations without suppressing or evaluating them. The present study revealed that the maladaptive focusing strategy decreased parasympathetic activity and enhanced following negative emotion. Additionally, we investigated the influence of a serotonin transporter gene polymorphism on the two types of emotion regulation. As a result, participants with SS alleles of the serotonin transporter gene showed more negative emotions in the maladaptive than in the adaptive focusing manipulation associated with reducing parasympathetic activity. In contrast, although participants with L alleles showed reduced parasympathetic activity in the maladaptive condition, no such differences were observed in subjective emotions between the conditions. These results are consistent with the evidence of greater emotion regulation ability in individuals with L alleles compared to those with S alleles.

The change in hormonal and immune state of university male students who were engaged in his graduation examination was investigated as a behavioral medicine study targeting on chronic stress. With regard to biomarkers of human hormonal and immune state, salivary secretory substances, Immunoglobulin A (IgA), Cortisol, Chromogranin (CgA), and dehydroepiandrosterone (DHEA), were assayed about a week before and 2 weeks after the day of oral defense of the graduation examination for 20 male students. As a result, the salivary immune substance, IgA, significantly decreased (p<0.001), while other biomarkers showed no significant change. In conclusion, it was suggested that IgA can be a promising candidate for a chronic stress marker.

Change blindness studies using explicit behavioral measures have revealed that humans are remarkably poor at explicitly detecting changes between two successive visual images until focused attention is drawn to the changes, which supports the notion that outside the range of focused attention, our mental representations of the visual world are so volatile as to be unable to support detection of changes. However, change blindness studies using implicit behavioral measures have revealed that changes outside the range of focused attention might be detected even in the absence of awareness, which supports the possibility that our mental representations are not so volatile as has been suggested. The purpose of the present study was to provide further evidence for implicit change detection using event-related brain potentials (ERPs). For this purpose, we compared ERPs elicited on trials where color changes were present but participants failed to report the presence of changes (Change blindness trials) and ERPs on trials where changes were absent and participants correctly did not report the presence of changes (No-change trials). The result showed that compared to No-change trials, Change blindness trials elicited a frontal/central positivity at around 160-180 ms, which is highly consistent with the result of Fernandez-Duque et al. [D. Fernandez-Duque, G. Grossi, I.M. Thornton, H.J. Neville, Representation of change: separate electrophysiolocal markers of attention, awareness, and implicit processing, J. Cogn. Neurosci. 15 (2003) 491-507] who firstly reported an ERP correlate of implicit change detection. This result provides further evidence for implicit change detection, which supports the notion that even outside the range of focused attention, our mental representations of the visual world are robust at least enough to support implicit detection of changes. © 2008 Elsevier Ireland Ltd.

Recent studies demonstrated that an acute psychological stressor elicited transient changes in lymphocyte redistribution. Earlier studies had established that CD3-CD16+CD56+ natural killer cells (NK cells) increased remarkably in peripheral blood circulation and that the amount of lymphocyte redistribution in NK cells was dependent on the CD62L expression density.
Specifically, CD62L- cells were mobilized more pronouncedly than were CD62L+ cells. These results led us to hypothesize that such different reactivity causes different temporal characteristics between CD62L+ and CD62L- lymphocyte subsets.
The present study was conducted to examine this issue. Ten female participants experienced a 10-minute baseline period and performed a 10-minute mental arithmetic task as an acute psychological stressor. Blood samples for measuring the proportions of CD62L+ or CD62L- NK cells and CD62L+ or CD62L- T cells were obtained immediately after each period and every 2 min during the task. As expected, CD62L+ and CD62L- NK cells showed different reactivity in response to the stressor and showed different temporal characteristics. That is, the elevation of CD62L- NK cells reached a significant level at I min after the initiation of the stressor, while CD62L+ NK cells took 8 min to show a tendency of elevation. Although CD3+ T cells showed different reactivity between CD62L cell types, they did not show different temporal characteristics. These findings suggest that the expression of CD62L modulates not only the amount of redistribution but also the temporal characteristics of the redistribution of NK cells. (C) 2008 Elsevier B.V.
