Intensity-dependent associations of physical activity and cardiorespiratory fitness with hair cortisol concentrations in the context of lifetime air pollution exposure.

Stress

Small cross-sectional observational study with a single biomarker endpoint and unexpected directional finding (vigorous activity associated with higher cortisol) that requires mechanistic clarification and replication before clinical interpretation.

Identification of genes and pathways associated with chronic restraint stress-induced anxiodepressive-like behaviors in female mice by transcriptomic and genome-wide DNA methylation combinational-analysis.

Stress

Mechanistic study in animal model identifying putative epigenetic pathways associated with stress-induced behavior; does not test a therapeutic intervention or establish causal mechanisms in humans.

The association between pubertal timing and diurnal cortisol activity in middle adolescence.

Stress

Prospective cohort study with adequate sample size showing a specific association between early menarche and cortisol awakening response in girls, but limited by cross-sectional cortisol measurement, modest effect size, and no effect in boys.

Antidepressant-like effects of valproic acid in rodents go back to the 1980s: a comment to enrich the reviewed evidence by Goudarzi et al. (2026) "Valproic acid effects on stress-induced depression-like behavior in rodent models: a systematic review and meta-analysis".

Stress

Historical commentary confirming antidepressant-like effects of valproic acid in rodent models first demonstrated in the 1980s, supporting recent meta-analytic findings but not providing new primary evidence.
