Mathematical Proof of Genomic Amino Acid Composition Homogeneity Based on Putative Small Units

The amino acid composition calculated from a gene assembly coding more than 3,000-7,000 amino acid residues represents the species specific amino acid composition based on the complete genome. In the present mathematical study, the 17 amino acid composition based on the sample size, 3,000-7,000, represents an amino acid composition with 95% level simultaneous confidence intervals for all amino acid probabilities in the sample. A genomic structure is constructed homogeneously with putative small units coding similar amino acid compositions under a mathematical rule

Similarity of Amino Acid Composition Based on Gene Assembly and Different Gene - size Distributions among the 11 Chromosomes in Encephalitozoon cuniculi

The amino acid composition and the gene-size distribution based on the complete genome of Encephalitozoon cuniculi were analyzed. The amino acid compositions based on the 11 chromosomes of Encephalitozoon cuniculi were almost identical, whereas the distribution patterns of gene-size among the chromosomes slightly differed. Thus, the genome is constructed with gene assemblies which show similar amino acid compositions, and which do not have the restricted boundaries

1998年に,中国・遼寧省の瀋陽市において,大気汚染データを収集し,市内の20小学校の学童1年と6年の男児3,961人,女児3,948人,計7,909人について,呼吸器症状,家庭環境因子などに関する調査を行い,その資料について検討を加えた.瀋陽市の大気汚染物質濃度は, S0_2とTSP,S0_2とN0_2, N0_2とTSPとの間に有意な相関が認められ,瀋陽市での大気汚染は, S0_2とTSPの他, NO_2汚染が加わっていると考えられた.学童の呼吸器症状有症率には,男女差は認められなかった.学年別では1学年の「せき」「喘鳴」の有症率が有意に高かった.汚染区分別には,対照区,清潔区,中汚染区,汚染区の順に呼吸器症状有症率が高くなる傾向があった.呼吸器症状有症率と「生活に及ぼす影響」および「アレルギー素因」との関係では,それぞれ「あり」のものは,呼吸器症状有症率が有意に高かった.気管支喘息の学童におけるアレルギー性疾患の合併は,アレルギー性皮膚炎が14.5%,アレルギー性鼻炎が13.8%にみられ,アレルギー疾患の合併率も,気管支喘息なしのものに比べて有意に高かった.Among 7,909 school children (3,961 males and 3,948 females) between 6 and 12 years of age in Shenyang, the capital city of Liaoning province in China, we investigated the prevalence of respiratory diseases such as bronchial asthma and wheeze, in addition to home and environmental factors such as air pollution during the winter in 19138, and evaluated the relationship between the prevalence of respiratory diseases and home and environmental factors, including air pollution. Correlation analysis of the air pollutant concentration in Shenyang showed significantly correlations between S0_2 and TSP, S0_2 and N0_2, and between N0_2 and TSP, suggesting the involvement of S0_2, TSP, and N0_2 in air pollution in Shenyang. Although the prevalence of respiratory diseases did not significantly differ between boys and girls, the prevalence of coughing and wheeze was significantly higher in first grade pupils. The highest prevalence of respiratory diseases was noted in a markedly polluted district, followed in order by respiratory diseases in a moderately polluted district, non-polluted district, and the control district. The prevalence of respiratory diseases was significantly higher in school children showing a positive relationship between respiratory symptoms and the influence on their daily life, and between respiratory symptoms and the presence of allergic predisposition than those who did not show such relationships. The percentage of asthmatic children who were complicated by allergic dermatitis was high (14.5%), followed in order by the percentage of such children complicated by allergic rhinitis (13.8%), pollen allergy, and allergic conjunctivitis
