Health Literacy and Internet Use Among Japanese Older Adults: A Gender-Stratified Cross-Sectional Analysis of the Moderating Effects of Neighborhood Relationships.

: Internet use positively impacts mental health in older adults, with health literacy (HL) playing a key role. While social networks may complement individual HL, the role of neighborhood relationships in this association, particularly by gender, remains unclear. This study examined how the association between HL and Internet use among older adults was modified by neighborhood relationships.

The Development of a Selective Colorimetric Sensor for Cu and Zn in Mineral Supplement with Application of a Smartphone Paper-Based Assay of Cu in Water Samples.

Herein, we developed a colorimetric method for the determination of Cu and Zn using NBD-G as a novel selective metal sensor. NBD-G was easily synthesized by a nucleophilic substitution reaction between 4-chloro-7-nitro-2,1,3-benzoxadiazole (NBD-Cl) and Girard's Reagent P. The NBD-G solution is yellow, but when it reacts with Cu and Zn, its color changes selectively to red (510 nm) and orange (480 nm), respectively.

A Real-Time Web-Based Intervention with a Multicomponent Group-Based Program for Older Adults: Single-Arm Feasibility Study.

Frailty is a growing public health challenge in Japan's rapidly aging population, where 28.8% are aged ≥ 65. While multicomponent interventions have shown potential in preventing frailty, traditional face-to-face programs face accessibility challenges.

Impact of uterine displacement on T-weighted image quality in the female pelvic MRI.

Despite the importance of T-weighted image in clinical practice, artifacts can significantly degrade image quality and affect diagnosis. This study quantitatively analyzed uterine displacement and surveyed the relationship between the image quality of fast-spin-echo-T-weighted image of the female pelvis and quantitative value of uterine displacement. Overall, 147 women (mean age, 46.
