In natura heart rate variability predicts subsequent alcohol use in individuals in early recovery from alcohol use disorder.

Impairment in autonomic self-regulatory functioning reflected by reduced heart rate variability (HRV) is a common feature of alcohol use disorder (AUD) and is believed to heighten AUD relapse risk. However, to date, no study has explored associations between in natura HRV and subsequent alcohol use among individuals seeking AUD recovery. In this study, 42 adults in the first year of a current AUD recovery attempt were monitored for 4 days using ambulatory electrocardiogram, followed by 90 days of alcohol use monitoring using timeline follow-back.

Cotranslational folding allows misfolding-prone proteins to circumvent deep kinetic traps.

Many large proteins suffer from slow or inefficient folding in vitro. It has long been known that this problem can be alleviated in vivo if proteins start folding cotranslationally. However, the molecular mechanisms underlying this improvement have not been well established.
