Hypertrophic scarring occurs after deep dermal wounds. Our understanding of the etiology is poor; one reason is the lack of an animal model. In 1972, Silverstein described scarring in the Duroc pig but the model was never confirmed nor disproved. Another reason, as we previously suggested, is that hypertrophic scarring only occurs within regions of human(More)
A genomic DNA library of Bifidobacterium longum ATCC15707 was transfected into an Escherichia coli strain deficient in both HU and IHF, the growth of which is cold-sensitive because of the deficiency in these proteins. Cold-resistant colonies were selected and the DNA was cloned and sequenced. A polypeptide consisted of 93 amino acids, a predicted molecular(More)
Keloid is a clinically intractable disease that causes disfigurement, itching, and pain due to abnormal proliferation of fibroblasts and production of collagen. Pirfenidone is a novel anti-fibrotic agent that inhibits the progression of fibrosis occurring in the keloid lesions of the lung and kidney. In order to examine whether pirfenidone has a therapeutic(More)
The anatomy of the intermuscular septum (IMS) of the lower leg has been studied in 10 legs of 10 cadavers. The IMS was well developed in the distal half of the lower leg and its vascular supply from the posterior tibial artery was frequently seen at 60mm proximal from the tip of the medial malleolus. We advocate that these anatomical features contribute to(More)
The ABLS course sponsored by the ABA has not yet been made available in Japan, although it is strongly desired. During the 3 years between 2006 and 2008, authorized ABLS provider courses were given once a year in Japan as part of preparations to reach an agreement between the ABA and the JSBI for the continuation of ABLS provider courses in Japan. These(More)
Participatory sensing produces incomplete sensor data. Thus, we have to fill in the gaps of any missing values in the sensor data in order to provide sensor-based services. We propose a method to estimate a missing value of incomplete sensor data. It accurately estimates a missing value by repeating two processes: selecting sensors locally correlated with(More)
