Synthesis of environmentally friendly energetic cocrystal derived from commodity chemicals.

Ammonium nitrate (AN) is a green oxidizer in the field of energetic materials. However, hygroscopicity and phase transitions have prevented AN from being put into practical use. To address these two drawbacks, a cocrystallization technique was applied to AN in this study.

Changes in the frequency and amount of alcohol intake before and during the COVID-19 pandemic.

Objectives: Concerns have been raised regarding the impact of the COVID-19 pandemic on alcohol consumption patterns, which can have implications for public health. In this descriptive study, we aimed to show the change in the frequency and amount of alcohol consumption in Japan before and during the COVID-19 pandemic periods.

Methods: We analyzed data from annual health checkups among Japanese workers from April 2018 to March 2021.

Possible determinants of physical fitness in Japanese school children: A cross-sectional study.

Background: Physical fitness is one of the most important health indicators in children. Although appropriate body composition or certain lifestyle factors such as frequent physical activity are thought to improve physical fitness, results of previous studies are inconsistent, and most studies were from Western countries.

Objectives: We investigated associations of body composition and modifiable lifestyle factors such as physical activity, screen time, diet and sleep duration with physical fitness in Japanese primary school children.

Molecular-Resolution Imaging of Ionic Liquid/Alkali Halide Interfaces with Varied Surface Charge Densities via Atomic Force Microscopy.

When in contact with charged solid surfaces, ionic liquids (ILs) are known to form solvation structures consisting of alternating cation and anion layers. This phenomenon is considered to originate from the adsorption layer of counterions overcompensating the surface charge, so-called overscreening. However, the response of these layers to surfaces with near-zero or extremely high surface charge density (σ) remains inadequately understood.

Male germ cell-associated kinase is required for axoneme formation during ciliogenesis in zebrafish photoreceptors.

Vertebrate photoreceptors are highly specialized retinal neurons that have cilium-derived membrane organelles called outer segments, which function as platforms for phototransduction. Male germ cell-associated kinase (MAK) is a cilium-associated serine/threonine kinase, and its genetic mutation causes photoreceptor degeneration in mice and retinitis pigmentosa in humans. However, the role of MAK in photoreceptors is not fully understood.
