Few studies have reported an association between diversity in productive activities and life satisfaction; hence, this cross-sectional study conducted in Japan aimed to clarify this association. We assessed the life satisfaction of 4,498 Japanese community-dwelling older adults engaged in productive activities (e.g., paid work, volunteering, taking care of children, and supporting others) using the Life Satisfaction Scale. We took the sum of the number of engaging productive activities as the diversity in productive activities score. A dose-response relationship was observed for each additional productive activity on life satisfaction. Participants who engaged in one, two, three, or four productive activities were more likely to have higher life satisfaction than those who did not engage; the odds ratios (95 % confidence intervals) were 1.19 (1.02-1.39), 1.19 (1.00-1.42), 1.71 (1.37-2.13), and 2.27 (1.58-3.27), respectively. Diversity in productive activities may enhance higher life satisfaction likelihood among Japanese community-dwelling older adults.

Copper ions are essential elements in the human body and participate in various physiological activities in the bodies of organisms. Herein, an ultrasensitive electrochemical biosensor was developed for detection of copper ions (Cu) based on FeO@Au magnetic nanoparticles (FeO@Au MNPs) and a Cu-dependent DNAzyme assisted nicking endonuclease signal amplification (NESA) strategy. dsDNA is formed by a hybridization reaction between DNA S2 and S1 immobilized on the surface of FeO@Au MNPs.

Dispersing iridium onto high-specific-surface-area supports is a widely adopted strategy to maximize iridium utilization in anode catalysts of proton exchange membrane water electrolysis (PEMWE). However, here we demonstrate that the overall cell performance, including initial efficiency and long-term stability, does not benefit from the typical high specific surface area of catalyst supports. The conventional understanding that high iridium utilization on high-specific-surface-area supports increases activity holds only in aqueous electrolytes, while under the typical working conditions of PEMWE, the mass transport within the anode catalyst layers plays a more significant role in the overall performance.

Aims: The increasing antimicrobial resistance, particularly in Acinetobacter baumannii, complicates the treatment of infections, leading to higher morbidity, mortality, and economic costs. Herein, we aimed to determine the in vitro antimicrobial, synergistic, and antibiofilm activities of colistin (COL), meropenem, and ciprofloxacin antibiotics, and curcumin, punicalagin, geraniol (GER), and linalool (LIN) plant-active ingredients alone and in combination against 31 multidrug-resistant (MDR) A. baumannii clinical isolates.

Purpose: To evaluate the efficacy and underlying mechanism of advanced optimal pulse technology intense pulsed light (AOPT) in low-energy triple-pulse long-width mode (AOPT-LTL) for melasma treatment.
Methods: An in vivo guinea pig model of melasma was established through progesterone injection and ultraviolet B radiation. Three sessions of AOPT-LTL treatment were performed weekly.

Electrochemical nitrogen fixation-a sustainable pathway for converting abundant N into NH using renewable energy-holds transformative potential for revolutionizing artificial nitrogen cycles. Nevertheless, even the state-of-the-art catalytic systems also suffer from inadequate N adsorption capacity, which critically limits ammonia production rates and Faradaic efficiency (FE). To overcome this bottleneck, we strategically leveraged the antiferroelectric properties of SnO to establish dipole-dipole interactions with N molecules, synergistically enhancing both N adsorption and activation kinetics.
