In this paper, a method for real-time tracking of moving objects is proposed. We applied Kalman particle filter (KPF) to color-based tracking. This KPF is a particle filter including the principle of Kalman filter, and it was adopted to the object contour tracking. We modified this KPF for color-based tracking. This modified KPF can approximate the(More)
Utrophin is a widely expressed paralogue of dystrophin, the protein responsible for Duchenne muscular dystrophy. Utrophin is a large spectrin-like protein whose C-terminal domain mediates anchorage to a laminin receptor, dystroglycan (DG). The rod domain, composed of 22 spectrin-like repeats, connects the N-terminal actin-binding domain and the C-terminal(More)
We examined the relationship between the distribution of Legionella bacteria and various physicochemical characteristics of hot springs in Japan. Legionella bacteria were isolated from 52 (49.5%) out of 105 water samples, particularly from outdoor hot springs (67.3%). The bacterial count in the water samples positive for Legionella (86.5%) ranged from 10(1)(More)
Using a neonatal mouse model of Cryptosporidium parvum infection, we investigated whether apoptosis of epithelial cells was induced in the small intestine. At the time when the number of C. parvum oocysts in the ileum was maximal, columnar goblet cells and absorptive cells showed a decrease in the ileal epithelium that was accompanied by a significant(More)
Overexpression of atypical protein kinase Cλ/ι (aPKCλ/ι), a regulator of cell polarity, is frequently associated with the poor prognoses of several cancers, including gastric cancer. Recent studies revealed a molecular link between aPKC and KIBRA, an upstream regulator of tumor suppressor Hippo pathway that regulates cell proliferation and apoptosis.(More)
In this paper, a method for real-time tracking of moving objects or pedestrians is proposed. Especially, we tackled to track an object whose part was temporally occluded or which traversed in front of the cluttered background. Furthermore, we tried to obtain the accurate trajectory of the center of it stably even then. For the problems, we present a(More)
Killing of Legionella pneumophila by an antimicrobial ceramic was evaluated during culture in nine kinds of hot spring water at 40 degrees C. After 24 hours, the efficacy against L. pneumophila varied, depended on water quality. The strongest antibacterial effect was seen in chloride hot spring water from Wakayama and in deionized water. In four hot spring(More)
To evaluate the efficacy of an antimicrobial ceramic for killing Legionella strains in vitro, bacteria were exposed to the ceramic soaked in PBS at 25 degrees C or 42 degrees C. The number of L. pneumophila began to decrease significantly after 4 h of exposure at 25 degrees C and reached < 10 log cfu/ml after 12 h. A similar significant decrease was also(More)
