Breathing and Relaxation Exercises Help Improving Fear of COVID-19, Anxiety, and Sleep Quality: A Randomized Controlled Trial.

To investigate the effects of breathing and relaxation exercises performed via telerehabilitation on fear, anxiety, sleep quality, and quality of life of individuals without coronavirus disease 2019 (COVID-19) during the ongoing pandemic. A prospective, randomized, controlled single-blind study. Fifty participants who had not been exposed to the COVID-19 virus earlier were randomly divided into experimental ( = 25) and control groups ( = 25).

Evaluation of tyrosol and farnesol as inducer in pigment production by Monascus purpureus ATCC16365.

This study focused on investigating the effect of exogenously applied two quorum sensing molecules (tyrosol and farnesol) on the synthesis of bioactive metabolites (pigments, lactic acid, ethanol, and citric acid) in Monascus purpureus ATCC16365. None of the tested concentrations (62.5, 125, 250, and 500 µl/L) of farnesol affected the synthesis of metabolites as well as cell growth.
