Reliable detection of circadian phase in humans using noninvasive ambulatory measurements in real-life conditions is challenging and still an unsolved problem. The masking effects of everyday behavior and environmental input such as physica...
Seasonal and diel variation of hormone metabolites in European stonechats: on the importance of high signal-to-noise ratios in noninvasive hormone studies [0.03%]
信号强度对非损伤性激素研究的重要性——欧洲石雀激素代谢物的季节和昼夜变化模式分析

Most vertebrates living in seasonal environments show seasonal reproductive cycles and diel rhythms. The rhythmicity in behavior and morphology is accompanied by diel and seasonal patterns of hormone secretions. In small animals, the invest...
Synchronized circadian bioluminescence in cave-dwelling Arachnocampa tasmaniensis (Glowworms) [0.03%]
洞穴居住的发光虫(Arachnocampsatasmaniensis)同步的昼夜生物荧光现象

David J Merritt
Larvae of the genus Arachnocampa, known as glowworms, are bioluminescent predatory insects that use light to attract prey. One species, Arachnocampa flava, is known to possess true circadian regulation of bioluminescence: light:dark cycles ...
Feeding time synchronizes clock gene rhythmic expression in brain and liver of goldfish (Carassius auratus) [0.03%]

Little is known about the feeding time dependence of clock gene expression in fish. The aim of the present study was to investigate whether a scheduled feeding time can entrain the rhythmic expression of several clock genes (period and cryp...
Temperature entrainment of the circadian cuticle deposition rhythm in Drosophila melanogaster [0.03%]

The cuticle deposition rhythm, which is observed in the apodeme of the furca in the thorax, is controlled by a peripheral circadian clock in the epidermal cells and entrained to light-dark (LD) cycles via CRYPTOCHROME (CRY) in Drosophila me...
Pigment-dispersing factor affects nocturnal activity rhythms, photic entrainment, and the free-running period of the circadian clock in the cricket gryllus bimaculatus [0.03%]
色素分散因子影响蟋蟀昼夜节律行为、光周期同步和自由运转周期中的视黄醇时钟功能

Pigment-dispersing factor (PDF) is a neuropeptide widely distributed in insect brains and plays important roles in the circadian system. In this study, we used RNA interference to study the role of the pigment-dispersing factor (pdf) gene i...
Partial sleep deprivation reduces phase advances to light in humans [0.03%]
睡眠不足会减小光照下的相位提前现象（对人体生物钟的影响）

Partial sleep deprivation is increasingly common in modern society. This study examined for the first time if partial sleep deprivation alters circadian phase shifts to bright light in humans. Thirteen young healthy subjects participated in...
Novel wheel running blocks the preovulatory luteinizing hormone surge and advances the hamster circadian pacemaker [0.03%]
跑步轮跑新抑制大仓鼠排卵黄体生成素激增并提前大仓鼠昼夜节律起搏器
S J Legan,K M Franklin,X-L Peng et al.
S J Legan et al.
In rodents, the preovulatory luteinizing hormone (LH) surge is timed by a circadian rhythm. We recently reported that a phenobarbital-induced delay of the estrous cycle in Syrian hamsters is associated with an approximately 2-h phase advanc...

Although overt diurnal rhythms of behavior do not begin until well after birth, molecular studies suggest that the circadian clock may begin much earlier at a cellular level: mouse embryonic fibroblasts, for example, already possess robust ...

In mammals, a pacemaker in the suprachiasmatic nucleus (SCN) is thought to be required for behavioral, physiological, and molecular circadian rhythms. However, there is considerable evidence that temporal food restriction (restricted feedis...
