Investigation of the 1-week effect of traffic light nutrition labeling on diet selection among Japanese university students: a randomized controlled trial.

Background: The method of displaying nutrition information labels on the front of food packaging (FOP: Front of Pack) has been implemented worldwide to prevent lifestyle-related diseases. This study aimed to investigate whether the use of the UK's Traffic Light Food (TLF) label, known as the FOP label, influences the dietary choices of Japanese youth and promotes healthy dietary choices.

Methods: Diet selection was performed for one week each during the baseline and intervention periods.

Evaluating the effectiveness of applying aroma seals to masks in reducing stress caused by wearing masks: A randomized controlled trial.

During the COVID-19 pandemic, face masks on patients and healthy people have been recommended to prevent airborne transmission of the virus. This increased the number of people who felt stressed while wearing masks. In this study, we investigated the stress-relieving effects of attaching aroma seals to masks.

Relieving psychological stress and improving sleep quality by bergamot essential oil use before bedtime and upon awakening: A randomized crossover trial.

Objectives: The COVID-19 pandemic increased psychological stress and decreased sleep quality, especially among young people. Aromatherapy alleviates psychological stress, and bergamot essential oil helps improve depression. This study aimed to verify whether bergamot essential oil use alleviates psychological stress due to the COVID-19 pandemic and improves sleep quality and morning wakefulness.

Effectiveness of Displaying Traffic Light Food Labels on the Front of Food Packages in Japanese University Students: A Randomized Controlled Trial.

Nutrition labeling on the front of food packages has been implemented worldwide to help improve public health awareness. In this randomized double-blind controlled trial, we used a Google Forms questionnaire to evaluate the effectiveness of nutrition labeling on food packages in university students. The questionnaire, ultimately completed by 247 students, included 15 dietary images from which they were asked to choose what they wanted to eat for breakfast, lunch, and dinner the following day.

Causes of anxiety among teachers giving face-to-face lessons after the reopening of schools during the COVID-19 pandemic: a cross-sectional study.

Background: Coronavirus infections are spreading rapidly worldwide, and primary and middle schools are closed in many countries. After the state of emergency was lifted in Japan, schools have reopened, and teachers are conducting face-to-face classes while maintaining safety precautions. This study aimed to assess the factors contributing to infection-related anxiety and educational anxiety among teachers conducting face-to-face classes during the COVID-19 pandemic after schools reopened.

Correction to: Laxative effect of repeated Daiokanzoto is attributable to decrease in aquaporin-3 expression in the colon.

The article Laxative effect of repeated Daiokanzoto is attributable to decrease in aquaporin-3 expression in the colon, written by Risako Kon, Miho Yamamura, Yukari Matsunaga, Hiroshi Kimura, Moe Minami, Saki Kato, Nobutomo Ikarashi, Kiyoshi Sugiyama, was originally published electronically on the publisher's internet portal (currently SpringerLink) on 27 January 2018 without open access.

Laxative effect of repeated Daiokanzoto is attributable to decrease in aquaporin-3 expression in the colon.

Daiokanzoto (DKT) exerts its laxative effect via colonic inflammation caused by sennoside A in Daio (rhubarb). Previously, we showed that the laxative effect of sennoside A is related to decreased aquaporin-3 (AQP3) expression in mucosal epithelial cells due to colonic inflammation. We also found that a combination of glycyrrhizin, an ingredient in Kanzo (glycyrrhiza), and sennoside A attenuates the inflammatory response induced by sennoside A and reduces its laxative effect.
