Similar Subgraph Retrieving for Japanese Historical Document Search System
Hiroaki Nagaoka,Mitsuru Nakata,Qi-Wei Ge,Makoto Yoshimura 대한전자공학회 2015 ITC-CSCC :International Technical Conference on Ci Vol.2015 No.6
In this paper, we propose a retrieval method of similar subgraphs in order to obtain similar partial images used in Japanese historical documents image retrieval system. In our system, the structure of characters is represented by a feature graph, and the structure of a string of each line of Japanese historical documents is stored as a feature graph which is called “document graph”. The structure of a string to be searched is specified as a feature graph that is called “search graph”. A search graph contains an “essential graph”, which shows an indispensable structure included in search results. The processes to search similar partial images are as follows: (1) get subgraphs of document graphs that are isomorphic to the essential graph, and construct candidates of search result from these subgraphs; (2) remove improper candidates based on some conditions; (3) calculate the similarities between remaining candidates and the search graph (these remaining candidates are called “similar subgraph”); (4) clip the partial areas as the search results, which correspond to similar subgraphs with high similarity from Japanese historical document images.

We examined the reactivity of the N-hydroxyamino derivative of a carcinogenic heterocyclic amine, 2-amino-1-methyl-6-phenylimidazo[4,5-b]pyridine (PhIP), after its O-acetylation with four 2'-deoxyribonucleoside 3'-monophosphates. ^32P-Postlabeling analysis demonstrated that the levels of adducts with 2'-deoxyguanosine 3'-monophosphate were much higher than those with the other three nucleotides. ^IH-NMR, mass spectral and UV absorption spectral analyses of the major adducts formed by N-acetoxy-PhIP with 2'-deoxyguanosine and with its phosphate esters indicated that PhIP bound at the C-8 position of guanine, as previously demonstrated with other heterocyclic amines.

BACKGROUND/OBJECTIVES: Recent studies have reported an association of the angiotensin II type 2 receptor (AT2R) 3123Cytosine/Adenine (3123C/A) polymorphism with essential hypertension and cardiovascular diseases. The purpose of the study was to investigate whether the AT2R 3123C/A polymorphism affects blood pressure for free-living hypertensive men during a 5-month intervention period. SUBJECTS/METHODS: The subjects were free-living hypertensive Japanese men aged 40 to 75 years who agreed to intervention in the period from 2004 to 2011. Detection of the AT2R 3123C/A polymorphism was determined by polymerase chain reaction. The dietary intervention was designed to decrease salt level and to increase potassium level through cooking instructions and self-monitoring of the diet. The exercise session consisted of activities such as stretching, resistance training, and walking. Blood pressure, urinary sodium and potassium excretion, dietary and lifestyle data, and non-fasting venous blood sample were collected at baseline and after the intervention period. RESULTS: Thirty nine subjects were eligible for participation and the follow-up rate was 97.4%. The C allele proportion was 57.9%. AT2R 3123C/A polymorphism was X-chromosome-linked, therefore we analyzed the C and A genotypes. At baseline, no significant differences were observed between the genotype groups. After the intervention, there were no significant differences in lifestyle habit between the groups. Nevertheless, the estimated salt excretion (g/day) was significantly decreased only in the C genotype (13.0-10.3, P = 0.031). No significant change was observed in systolic blood pressure (SBP) (mmHg) in the A genotype, but a significant decrease was observed in the C genotype (150.0-141.5, P = 0.024). CONCLUSTIONS: In the C genotype, it might be easy to improve SBP through lifestyle intervention in free-living hypertensive Japanese men, however generalization could not be achieved by the small sample size.
