Blue light at 405, 420, and 450 nm produced wavelength- and dose-dependent inactivation of multiple food-related bacteria. At the same dose, lower wavelengths achieved greater reductions; 405 nm showed the highest inactivation overall (e.g., ~7.5 log CFU/mL r…
Ambient visible light or controlled-intensity visible-spectrum LED induced an effector gene in non-neuronal tissues via bZIP transcription factors ZIP-2 and CEBP-2, with stronger induction at shorter wavelengths and independence from known blue light receptor…
Embryos incubated under different light spectra showed a significant increase in telomere length across early development independent of spectrum. Red light and darkness were described as potent stressors (proteotoxic stress and energy imbalance), while green…
Primary human gingival fibroblasts showed minor reductions in viability after 457 nm blue light across 3–90 J/cm2, while keratinocyte proliferation and metabolic activity were enhanced. Violet light (415 nm) produced significant cytotoxic effects. Blue light …
In 61 participants (32 with T2D; 29 without), dynamic structural equation modelling identified 18 significant within-person associations between smartphone-derived sleep/movement behaviours and subsequent daily mood; 17 associations indicated a positive effec…
In a within-subjects comparison of short breaks with smartphone use versus sitting quietly, there were no significant differences in mind wandering during breaks, subsequent 2-back task performance, or mind wandering during the subsequent task. Participants r…
Among 408 adolescents (204 males, 204 females), postural assessment showed head anteriorization and pelvic misalignment, with females having greater head and pelvic angular deviations. No significant associations were found between cell phone use and cervical…
In 502 participants with recurrent MDD, between-person higher step count and higher screen time were positively associated with performance-based cognitive assessments, while sleep duration showed a quadratic negative association; no within-person effects wer…
