Particles were characterized, and the inhibitory effects were studied on HeLa cells in vitro using cyclic voltammetry (CV). Voltammograms from the CV show that Fe3O4 NPs interaction with HeLa cells affected their electrochemical behavior. The nanoparticles formed with higher Fe3+/Fe2+ molar ratio (2.8  1) resulted in smaller crystallite sizes compared to those formed with lower Fe3+/Fe2+ molar ratio (1.4  1). The particles with the smallest crystallite size showed higher anodic peak currents, whereas the larger crystallite sizes resulted in lower anodic peak currents. The peak currents relate to cell inhibition and are confirmed by the half-maximum inhibitory concentration (IC50). The findings show that the particles have a different inhibitory mechanism on HeLa cells ion transfer and are promising to be further exploited for cancer treatment. The purpose of this study was to investigate the association between drinking habits and subjective symptoms of the oral cavity based on Japanese national statistical data. The subjects were 8,698 respondents of the Japan National Livelihood Survey 2013, in their 30s to 60s. The association between drinking habits and each survey item was investigated by contingency table analysis and binary logistic regression analysis. The proportion of people with drinking habits was 55.3% among men and 20.3% among women, and the proportion of men with drinking habits above the age of 40 years was high. Contingency table analysis indicated an association between drinking habits and the following items in men subjective symptoms ( < 0.01), chewing difficulty ( < 0.05), subjective impression of health ( < 0.01), smoking habit ( < 0.01), and income level ( < 0.01). Analysis indicated an association between drinking habits and hospital visits ( < 0.01) and smoking habits ( < 0.01) in woin the f
