Cross-sectional study on university students' mental health during the COVID-19 pandemic: Exploring the influence of adverse and positive childhood experiences.

Aim: This study examined the psychological impact of the COVID-19 pandemic on university students, focusing on how adverse childhood experiences (ACEs) and positive childhood experiences (PCEs) influence mental health.

Methods: A web-based survey was administered to 3000 university students from October 26 to 31, 2022, following the peak of the COVID-19 pandemic. Mental health assessments included the Japanese version of the Kessler Psychological Distress 6-Item Scale (K6) for depressive/anxiety symptoms, the Impact of Event Scale-Revised (IES-R-J) for distress, fear of COVID-19, and a three-item loneliness scale.

Association between work environment changes due to the COVID-19 pandemic and post-traumatic stress disorder in Japanese workers during the emergency declaration.

Aim: This study investigated the association between COVID-19 pandemic-related work environment changes and suspected post-traumatic stress disorder (PTSD) in Japanese workers.

Methods: A web survey of 1104 workers was conducted in Japan between February 24 and March 2, 2021. The Japanese version of the Impact of Event Scale-Revised and questions regarding work environments and COVID-19 pandemic-related lifestyle changes were used.

Nucleoprotein-enriched diet enhances protein synthesis pathway and satellite cell activation via ERK1/2 phosphorylation in unloaded rat muscles.

New Findings: What is the central question of this study? The purpose of this study was to determine whether the nucleotides in a nucleoprotein-enriched diet could ameliorate the unloading-associated decrease in soleus muscle mass and fibre size. What is the main finding and its importance? The results indicate that the nucleotides in the nucleoprotein-enriched diet could ameliorate the unloading-associated decrease in type I fibre size and muscle mass, most probably owing to the activation of protein synthesis pathways and satellite cell proliferation and differentiation via ERK1/2 phosphorylation. Thus, nucleotide supplementation appears to be an effective countermeasure for muscle atrophy.

A mechanical plant defense defines the opening of a phenological window for gall induction by Asphondylia aucubae (Cecidomyiidae: Diptera).

Many insect herbivores can only use hosts during a specific phenological stage, i.e., a phenological window.
