University “Health Café” for the Community-Dwelling Elderly: Effect of Continuous Health Interventions on Motivation and Consciousness of Life

A health intervention called a “health café” was held by the university to provide lectures and support for elderly residents in the nearby community. We clarified its effect and verified the possibility of the university becoming a place to support the community of elderly people living in the area. Seven “health cafés” were held from July 2017 to March 2018, and they included activities such as cooking and exercise classes. A questionnaire survey on dietary habits, health consciousness, and body composition of 35 community-dwelling elderly (average age, 70 years; average BMI, 22.6) was conducted in the first and sixth sessions. Participants also regularly measured the amounts of activities for six months and their lifestyle changes were analyzed. Their eating habits were good, their health consciousness was higher than the average obtained from the Japanese national survey, and they actively participated in the health cafés. After six months, the participantsʼ motivation and consciousness of dietary habits and exercise increased, suggesting that the university has a role to play in supporting the elderly in the community. Further, similar programs and the accumulation of such motivated and energetic elderly data could contribute to the realization of a healthy society for the prevention of daily dysfunction.本研究の一部は JSPS 科研費基盤研究（C）（一般）課題番号 JP17K00789の助成を受けて実施した

Synthesis, Structure, and Thermal Stability of Silver(I) Coordination Polymers with Bis(pyridyl) Ligands Linked by an Aromatic Sulfonamide: One-Dimensional-Straight Chain, One-Dimensional-Columnar with Helical Components, and Two-Dimensional-Layer Network Structures

Three different types of coordination polymers, one-dimensional (1D) straight chain, 1D-columnar structure, and two-dimensional (2D) layer structure, have been prepared by the complexation of Ag­(I) ions with bis­(pyridyl) ligands linked by an aromatic sulfonamides and structurally characterized by single-crystal X-ray diffraction and thermogravimetric analysis. Structural analyses showed that the complexation of the 3-pyridyl ligand with AgOTf and the complexation of the 4-pyridyl ligand with AgBF₄ in CHCl₃/CH₃CN resulted in the formation of 1D straight-chain polymers. In the complexation of the 3-pyridyl ligand with AgBF₄ in CHCl₃/CH₃CN, the resulting continuous 1D columnar coordination polymers were formed containing a racemic mixture of left- and right-handed helices. Furthermore, the 2D-layer structure was constructed by the complexation of a 4-pyridyl ligand with AgSbF₆ in CHCl₃/MeOH

Frequency change-induced alternative potential waveform dependence of membrane damage to cells cultured on an electrode surface

In the present study, alternative potential stimulation with rectangular pulse, sine and triangular waveforms at 10 and 100 Hz was applied to cells cultured on an ITO electrode. As a result, we found that the alternating potential waveform dependence induced by the frequency on membrane damage of cells cultured on an electrode surface. The cell membrane damage was promoted by a rectangular pulse wave in comparison with sine and triangular waves, when alternating electrical potentials of 0 to +1.0 V at 100 Hz were loaded. In contrast, this waveform dependence was not observed when the frequency was 10 Hz. Furthermore, it was found that cell membrane damage was induced at positive potentials more than +0.8 V under the present experimental conditions
