The term masking refers to immediate responses to stimuli that override the influence of the circadian timekeeping system on behavior and physiology. Masking by light and darkness plays an important role in shaping an organism's daily patte...
Dissociation of ultradian and circadian phenotypes in female and male Siberian hamsters [0.03%]
Siberian仓鼠雄性和雌性超日周期和生物钟周期表型的分离

Three experiments addressed whether pronounced alterations in the circadian system yielded concomitant changes in ultradian timing. Female Siberian hamsters were housed in a 16L:8D photoperiod after being subjected to a disruptive phase-shi...

In insects, the role of circadian clocks in the temporal regulation of adult emergence rhythm under natural conditions has not previously been reported. Here we present the results of a study aimed at examining the time course and waveform ...
Large ventral lateral neurons determine the phase of evening activity peak across photoperiods in Drosophila melanogaster [0.03%]

The dual-oscillator model, originally proposed as a mechanism for how vertebrates adapt to seasonal changes, has been invoked to explain circadian entrainment in Drosophila melanogaster. Distinct subsets of neurons have been designated as "...
Does pupil constriction under blue and green monochromatic light exposure change with age? [0.03%]

Many nonvisual functions are regulated by light through a photoreceptive system involving melanopsin-expressing retinal ganglion cells that are maximally sensitive to blue light. Several studies have suggested that the ability of light to m...
Enhancement and suppression of ultradian and circadian rhythms across the female hamster reproductive cycle [0.03%]

The impact of ovarian hormones on hamster ultradian rhythms (URs) is unknown. We concurrently monitored URs and circadian rhythms (CRs) of home cage locomotor activity during the estrous cycle, pregnancy, and lactation of Syrian hamsters. U...

Fully mature enamel is about 98% mineral by weight. While mineral crystals appear very early during its formative phase, the newly secreted enamel is a soft gel-like matrix containing several enamel matrix proteins of which the most abundan...
Light acts on the zebrafish circadian clock to suppress rhythmic mitosis and cell proliferation [0.03%]

A fundamental role of the circadian clock is to control biochemical and physiological processes such that they occur an optimal time of day. One of the most significant clock outputs from a clinical as well as basic biological standpoint is...
The colony environment, but not direct contact with conspecifics, influences the development of circadian rhythms in honey bees [0.03%]
群体环境而不是与同种个体的直接接触影响蜜蜂昼夜节律的形成

Honey bee (Apis mellifera) workers emerge from the pupae with no circadian rhythms in behavior or brain clock gene expression but show strong rhythms later in life. This postembryonic development of circadian rhythms is reminiscent of that ...
Is the sex communication of two pyralid moths, Plodia interpunctella and Ephestia kuehniella, under circadian clock regulation? [0.03%]
害虫谷蠹和印度谷螟的求偶通讯受生物钟调节吗?

Females of the Indian meal moth, Plodia interpunctella, and females of the Mediterranean flour month, Ephestia kuehniella (both Lepidoptera: Pyralidae), exhibit daily rhythms in calling behavior. The peak in P. interpunctella calling occurs...
