The purpose of this study was to examine the relationship between the family relationships recognized by children and mental health after becoming adults, with emphasis on the forms of recognition from the viewpoint of children. It consisted of an anonymous questionnaire survey using a multiple-choice and fill-in-the-answer format among 451 university students as the subjects. The questionnaire included an investigation into the gender, family relationship from the higher grades of elementary school to secondary school, self-esteem, self-efficacy, and the tendency towards depression and anxiety of the subjects. The results of this study suggested that the more balanced the psychological distance between family members, the lower the score showing a tendency towards anxiety, and vice versa. The results also suggested that the more balanced the psychological distance between family members, the lower the score showing a tendency towards depression, and vice versa. Therefore, it is assumed that the balance of the psychological distance between each member has a stronger impact on the tendency towards anxiety and depression than the length of the psychological distance. In terms of gender, there were no differences in self-esteem, self-efficacy, or the tendency of depression and anxiety. In conclusion, this study partially revealed how the family relationships recognized by children impact personality formation in the process of becoming adults.

Differences in dinucleotide frequencies of thermophilic genes encoding water soluble and membrane proteins

引用

Journal of Zhejiang University-Science B(Biomedicine & Biotechnology) 2011年第6期12卷 419-427页

作者： Hiroshi NAKASHIMA yuka KURODA Department of Clinical Laboratory Science Graduate Course of Medical Science and TechnologySchool of Health SciencesKanazawa University

The occurrence frequencies of the dinucleotides of genes of three thermophilic and three mesophilic species from both archaea and eubacteria were investigated in this study. The genes encoding water soluble proteins were rich in the dinucleotides of purine dimers, whereas the genes encoding membrane proteins were rich in pyrimidine dimers. The dinucleotides of purine dimers are the counterparts of pyrimidine dimers in a double-stranded DNA. The purine/pyrimidine dimers were favored in the thermophiles but not in the mesophiles, based on comparisons of observed and expected frequencies. This finding is in agreement with our previous study which showed that purine/pyrimidine dimers are positive factors that increase the thermal stability of DNA. The dinucleotides AA, AG, and GA are components of the codons of charged residues of Glu, Asp, Lys, and Arg, and the dinucleotides TT, CT, and TC are components of the codons of hydrophobic residues of Leu, Ile, and Phe. This is consistent with the suitabilities of the different amino acid residues for water soluble and membrane proteins. Our analysis provides a picture of how thermophilic species produce water soluble and membrane proteins with distinctive characters: the genes encoding water soluble proteins use DNA sequences rich in purine dimers, and the genes encoding membrane proteins use DNA sequences rich in pyrimidine dimers on the opposite strand.

Identification of sources of lead in the atmosphere by chemical speciation using X-ray absorption near-edge structure(XANES) spectroscopy

引用

Journal of Environmental Sciences 2014年第2期26卷 343-352页

作者： Kohei Sakata Aya Sakaguchi Masaharu Tanimizu Yuichi Takaku yuka Yokoyama Yoshio Takahashi Department of Earth and Planetary Systems Science Hiroshima University Kochi Institute for Core Sample Research Japan Agency for Marine-Earth Science and Technology Institute for Environmental Sciences

Sources of Pb pollution in the local atmosphere together with Pb species, major ions, and heavy metal concentrations in a size-fractionated aerosol sample from Higashi-Hiroshima （Japan） have been determined by X-ray absorption near-edge structure （XANES） spectroscopy, ion chromatography, and ICP-MS/AES, respectively. About 80% of total Pb was concentrated in fine aerosol particles. Lead species in the coarse aerosol particles were PbC204, 2PbCO3-Pb（OH）2, and Pb（NO3）2, whereas Pb species in the fine aerosol particles were PbC204, PbSO4, and Pb（NO3）2. Chemical speciation and abundance data suggested that the source of Pb in the fine aerosol particles was different from that of the coarse ones. The dominant sources of Pb in the fine aerosol particles were judged to be fly ash from a municipal solid waste incinerator and heavy oil combustion. For the coarse aerosol particles, road dust was considered to be the main Pb source. In addition to Pb species, elemental concentrations in the aerosols were also determined. The results suggested that Pb species in size-fractionated aerosols can be used to identify the origin of aerosol particles in the atmosphere as an alternative to Pb isotope ratio measurement.

Porphyromonas gingivalis,a periodontal pathogen,impairs post-infarcted myocardium by inhibiting autophagosome–lysosome fusion

引用

International Journal of Oral Science 2023年第4期15卷 626-639页

作者： yuka Shiheido-Watanabe Yasuhiro Maejima Shun Nakagama Qintao Fan Natsuko Tamura Tetsuo Sasano Department of Cardiovascular Medicine Graduate School of Medical and Dental SciencesTokyo Medical and Dental UniversityTokyoJapan

While several previous studies have indicated the link between periodontal disease (PD) and myocardial infarction (MI), theunderlying mechanisms remain unclear. Autophagy, a cellular quality control process that is activated in several diseases, includingheart failure, can be suppressed by Porphyromonas gingivalis (P.g.). However, it is uncertain whether autophagy impairment byperiodontal pathogens stimulates the development of cardiac dysfunction after MI. Thus, this study aimed to investigate therelationship between PD and the development of MI while focusing on the role of autophagy. Neonatal rat cardiomyocytes(NRCMs) and MI model mice were inoculated with wild-type P.g. or gingipain-deficient P.g. to assess the effect of autophagyinhibition by P.g. Wild-type P.g.-inoculated NRCMs had lower cell viability than those inoculated with gingipain-deficient P.g. Thisstudy also revealed that gingipains can cleave vesicle-associated membrane protein 8 (VAMP8), a protein involved in lysosomalsensitive factor attachment protein receptors (SNAREs), at the 47th lysine residue, thereby inhibiting autophagy. Wild-type P.g.-inoculated MI model mice were more susceptible to cardiac rupture, with lower survival rates and autophagy activity thangingipain-deficient P.g.-inoculated MI model mice. After inoculating genetically modified MI model mice (VAMP8-K47A) with wildtype P.g., they exhibited significantly increased autophagy activation compared with the MI model mice inoculated with wild-typeP.g., which suppressed cardiac rupture and enhanced overall survival rates. These findings suggest that gingipains, which arevirulence factors of P.g., impair the infarcted myocardium by cleaving VAMP8 and disrupting autophagy. This study confirms thestrong association between PD and MI and provides new insights into the potential role of autophagy in this relationship.

Fourteen patients were diagnosed as definitive, and 2 and 5 patients were probable and possible IgG4-ROD, respectively. Eyelid swelling was an initial symptom in 11 patients（52%） who did not show systemic involvements at a diagnosis. Fifteen patients received systemic corticosteroid administration, and all showed remission of inflammation. Among them, 10 patients did not recur, whereas 5 patients（33%） recurred during tapering. There were no significant difference between patients with or without recurrence in clinicopathological ***： In this study, female patients are more predominant in IgG4-ROD. While inflammation recurs in one-third of patients, this study do not identify factors associated with recurrence after systemic corticosteroid administration.
