Accurate identification of cell nuclei and their tracking using three dimensional (3D) microscopic images is a demanding task in many biological studies. Manual identification of nuclei centroids from images is an error-prone task, sometimes impossible to accomplish due to low contrast and the presence of noise. Nonetheless, only a few methods are available(More)
Remyelination is an important aspect of nerve regeneration after nerve injury, but the underlying mechanisms are not fully understood. Here, we show that meltrin-beta (ADAM19), a member of the ADAM (a disintegrin and metalloprotease) family, plays crucial roles in nerve regeneration after a crush injury to the sciatic nerves. The expression of meltrin-beta(More)
Based on the recently developed Gitaigo personality scale (Komatsu, Sakai, Nishioka, & Mukoyama, 2012), we investigated the relationship between perceived personality and leading/following roles in close friend dyads. Primary participants rated their own and one of their close friend's personality with Gitaigo personality scale. They also described who(More)
The objective of this study was to determine the concentration of serum l-arginine in healthy pregnant women and infant cord blood and to compare them with those in patients with pregnancy-induced hypertension (PIH). The serum concentration of l-arginine in normal pregnant women at early gestation (n = 186) was determined and analyzed based on maternal(More)
Gitaigo is a subtype of mimetic words (onomatopoeia) in the Japanese language, which can be regarded as words that imitate actions or states. This study develops a personality scale, with six subscales, using 60 gitaigo words as items for rating the personality of the self and others. We asked 1 054 participants to rate their own personality and 905(More)
Kinesiologic analysis of gait disorders, postural instabilities and abnormal movements is quite difficult to assess objectively by clinical observation, such as by specific scale and video recordings. In this study, we reported one of the aspects of the usefulness of three-dimensional motion analysis (Vicon Systems, Oxford, United Kingdom), which can(More)
This study investigated Japanese mimetic words "Gitai-go" that can describe personality, through classification based on factor analysis and correlation analysis with the Five Factor Personality Questionnaire (FFPQ). Japanese participants, mostly undergraduates (344 men and 702 women), were asked to rate themselves on a five point scale on each of 120(More)
