A biosignal measurement device is proposed which can improve measurement accuracy without forcing an excessive burden on subjects.A biosignal measurement device used for measurement of a biosignal in a head includes a support that can support the head, and an electrode provided to the support. The electrode has a plurality of teeth each including an annular portion in which a pair of linear members having conductivity are formed in an annular shape, and a rod-like portion in which the pair of linear members are wound in opposite directions and formed in a rod-like shape. The rod-like portion in each of the plurality of teeth is directly or indirectly fixed at one end to the support.

Disclosed herein is a method and apparatus for determining the base sequence of a nucleic acid molecule by cleaving a nucleic acid molecule of interest while controlling the cleavage site, measuring the change in mass which occurs in the nucleic acid molecule after the cleavage step, and acquiring the base information of the cleaved nucleic acid molecule from the data about the change in mass. The method and apparatus are based on the principle which is entirely different from that used for the conventional technique.

An object of the present invention is to clarify unelucidated aspects in the control mechanism of circadian rhythms. The present inventors have newly found that RORα (retinoic acid binding-receptor alpha; the same shall apply hereinafter) stimulates an induction of Bmal1 expression and also that the induction of Bmal1 expression is promoted under hypoxia. These findings strongly suggest the existence of a control mechanism of circadian rhythms that, when RORα expression is promoted under hypoxia or the like, an induction of Bmal1 expression is stimulated and, when the induction of Bmal1 expression is stimulated, binding between BMAL1 and CLOCK is stimulated and an induction of Per gene or Cry gene expression is stimulated. The present invention, therefore, has applicability as jet-lag regulating agents and anticancer agents.
摘要:
There is provided a method that achieves the prediction of a biological rhythm with high precision while minimizing the number of times a biological specimen is collected from a subject. There is also provided a method for predicting a biological rhythm of a subject on the basis of time series expression level data obtained by measuring expression levels of two clock genes in biological specimens collected from the subject three times within 24 hours, the clock genes having different phases of circadian cycles of a change in expression levels. In this method for predicting a biological rhythm, a biological rhythm can be predicted with particularly high precision by collecting a biological specimen from a subject three times within 24 hours at eight-hour intervals.

摘要:
The molecular reaction mechanism that associates the clock gene with stress is elucidated based on the finding that stress is accompanied by an increase in the expression level of Per1 gene in peripheral tissues, stress response does not change the circadian rhythm in peripheral tissues, and Per1 gene increases in its expression level dependently on the responsive element of glucocorticoid existing in its promoter region. This finding is used for stress evaluation. That is, stress can be evaluated for its presence or absence or degree by detection and determination of an increase in the transcript (mRNA) of Per1 gene in peripheral tissues (an increase in the protein coded by Per1 gene).
