Background: While negative life events (NLEs) have been linked to an increased risk of sleep disturbance among adolescents, the mechanisms of this impact still lack further examination. The current study aimed to explore whether intolerance of uncertainty (IU), a dispositional transdiagnostic vulnerability factor for psychopathology, could act as a mediator and/or moderator in the link from NLEs to sleep disturbance.
Methods: A longitudinal nested subsample of 54,240 Chinese adolescents (aged 9-19) were surveyed at baseline (Timepoint 1) and six months later (Timepoint 2).

The aim of this study was to investigate L-arabinose, a unique functional sugar that improves insulin resistance and intestinal environment while promoting probiotic proliferation, for its potential in preventing obesity induced by a high-fat and high-sugar (HFHS) diet in mice.
Methods: The L-arabinose group was intragastrically administered with 0.
