Purpose: This cross-sectional study examined the gut microbiota species associated with skeletal muscle mass reduction in a community-based sample of older Japanese adults.
Methods: The study included 744 participants (320 men and 424 women) aged 65-89 years (mean age: 73 years) with no history of treatment for colorectal, chronic kidney, or liver diseases. Bioelectrical impedance analysis was performed to estimate the appendicular skeletal muscle mass (ASM) of each participant.
Central blood pressure (BP) is more strongly associated with cardiovascular events than brachial BP. Few studies have described age-related changes in central BP in the general Japanese population. This study aimed to provide reference values for central BP parameters according to the age and sex, using data from 2964 participants aged 40-89 years (mean age: 60 years) who had no history of overt cardiovascular or chronic kidney disease and had not received antihypertensive, lipid-lowering, or hypoglycemic treatments.

- The investigation focused on the local structure of the two-dimensional layered material BiRhSe, which exhibits both superconducting and charge-density wave states.
- The study utilized X-ray fluorescence holography to analyze the crystal structure at temperatures of 300 K and 200 K, revealing significant changes in atomic arrangement around the critical temperature of 240 K.
- The results suggest a supercell structure for BiRhSe below the CDW transition, providing crucial insights into the relationship between the superconducting and charge-density wave states.
Article Synopsis
- The study focused on the structural and superconducting properties of the Bi-based superconductor BiRh(SeS) under varying pressure conditions.
- BiRhSe shows superconductivity with a transition temperature below 1.0 K and a charge density wave transition at 240 K, whereas BiRhS does not exhibit superconductivity but has a structural transition at 165 K.
- Researchers created samples of BiRh(SeS) and examined how its superconducting properties and phase transitions change with different ratios of Se to S, aiming to understand the relationship between these materials and their phase behavior under pressure.
Article Synopsis
- - The study compared the accuracy of impressions taken of hypermobile teeth in partially edentulous dental arches using digital and conventional methods, assessing a mandibular model with three target teeth.
- - Results showed that digital impressions significantly outperformed hydrocolloid impressions for two of the three teeth tested, while the accuracy of digital and silicone impressions was similar.
- - The research concluded that using an intraoral scanner (digital method) is preferable for minimizing hypermobile tooth deviations compared to hydrocolloid impressions, with the accuracy varying based on the specific tooth's location.
