Effects of different monochromatic light on growth performance and liver circadian rhythm of Yangzhou geese by Yingqing Xu, Yi Tang, Yiyi Cheng, Wen Yang, Jie Liu, Binbin Guo, Gang Luo, Huanxi Zhu

“…However, monochromatic light significantly down-regulated the gene expression, peak and amplitude of retinoic acid receptor-related orphan receptor α (RORα), as well as advancing or delaying the phase of the circadian rhythm. Among them, GL significantly up-regulated the gene expression of the melatonin receptors 1C (MEL1C); blue light (BL) significantly increased plasma melatonin concentration and IGF-1 concentration and significantly decreased the peak and amplitude of period 3 gene (PER3), resulting in almost no difference in the expression of PER3 at the six times; and red light (RL) significantly down-regulated the expression and the peak of MEL1C as well as the peaks and amplitudes of the seven liver clock genes, especially circadian locomotor output cycles kaput factor (CLOCK). …”

Organic Light-Emitting Diode with Color Tunable between Bluish-White Daylight and Orange-White Dusk Hue by Shih-Yun Liao, Sudhir Kumar, Hui-Huan Yu, Chih-Chia An, Ya-Chi Wang, Jhong-Wei Lin, Yung-Lee Wang, Yung-Chun Liu, Chun-Long Wu, Jwo-Huei Jou

“…The varying color of sunlight diurnally exhibits an important effect on circadian rhythm of living organisms. The bluish-white daylight that is suitable for work shows a color temperature as high as 9,000 K, while the homey orange-white dusk hue is as low as 2,000 K. …”
