Dissociative Oxygen Adsorption and Incorporation in CoO-Dispersed BaZrScO for PCFC Cathode.

The development of air electrodes with superior surface oxygen exchange properties at intermediate temperatures is crucial for improving the efficiency of protonic ceramic fuel cells. This study evaluated the surface exchange properties of CoO dispersed protonic conductors, BaZrScO. Although CoO is widely acknowledged as superior dissociative adsorption catalysts, there is still ambiguity regarding the enhancement mechanisms of their surface exchange properties by CoO, as well as their optimal composition to achieve high catalytic activity.

Application of Piezoelectric PLLA Braided Cord as Wearable Sensor to Realize Monitoring System for Indoor Dogs with Less Physical or Mental Stress.

We attempted to realize a prototype system that monitors the living condition of indoor dogs without physical or mental burden by using a piezoelectric poly--lactic acid (PLLA) braided cord as a wearable sensor. First, to achieve flexibility and durability of the piezoelectric PLLA braided cord used as a sensor for indoor dogs, the process of manufacturing the piezoelectric PLLA fiber for the piezoelectric braided cord was studied in detail and improved to achieve the required performance. Piezoelectric PLLA braided cords were fabricated from the developed PLLA fibers, and the finite element method was used to realize an e-textile that can effectively function as a monitoring sensor.

Factors related to among older residents participating in hillside residential community-based activities in Nagasaki City, Japan.

The present study aims to investigate the factors related to self-rated (purpose in life) among older residents participating in hillside residential community-based activities in Nagasaki City. A self-administered anonymous questionnaire survey was carried out with older residents participating in two hillside residential community-based activities in Nagasaki City, Japan. The questionnaire included questions on sociodemographic information (age, sex, family structure, education, and self-rated economic satisfaction), self-rated health, mental health status measured using Geriatric Depression Scale-15 (GDS-15), and self-rated ikigai score that was estimated using a visual analog scale.

Inhibition of an Allergen-Antibody Reaction Related to Japanese Cedar Pollinosis Using DNA Aptamers Against the Cry j 2 Allergen.

Japanese cedar pollinosis is one of the most prevalent allergies in Japan. Reducing the allergen content of pollen plays a major role in the alleviation of allergy symptoms. Aptamers, oligonucleotides with an affinity for specific molecules, have great potential for reducing allergic activity.

CDH13 Polymorphisms are Associated with Adiponectin Levels and Metabolic Syndrome Traits Independently of Visceral Fat Mass.

Aim: Visceral fat accumulation contributes to the development of metabolic syndrome. As visceral fat accumulation increases, adiponectin levels decrease; therefore, adiponectin provides a link between visceral fat accumulation and metabolic disorders. Genome-wide association studies (GWASs) have identified genetic variations in the cadherin 13 (CDH13) gene that are associated with adiponectin levels.
