Aging is associated with an earlier timing of circadian rhythms and a shorter phase angle between wake time and the timing of melatonin secretion or the core body temperature nadir. Light has a phase-dependent effect on the circadian pacema...
Time-dependent effects of dim light at night on re-entrainment and masking of hamster activity rhythms [0.03%]

Bright light has been established as the most ubiquitous environmental cue that entrains circadian timing systems under natural conditions. Light equivalent in intensity to moonlight (
Clock gene expression during chronic inflammation induced by infection with Trypanosoma brucei brucei in rats [0.03%]

African sleeping sickness is characterized by alterations in rhythmic functions. It is not known if the disease affects the expression of clock genes, which are the molecular basis for rhythm generation. We used a chronic rat model of exper...
Differential regulation of kiss1 expression by melatonin and gonadal hormones in male and female Syrian hamsters [0.03%]
促性腺激素和松果体激素通过性别依赖的表观遗传机制调控叙利亚仓鼠Kiss1基因表达的不同模式

In seasonal breeders, reproduction is synchronized to seasons by day length via the pineal hormone melatonin. Recently, we have demonstrated that Kiss1, a key activator of the reproductive function, is down-regulated in sexually inactive ha...
Effects of prd circadian clock mutations on FRQ-less rhythms in Neurospora [0.03%]

Rhythmic conidiation (spore formation) in Neurospora crassa provides a model system for investigating the molecular mechanisms of circadian rhythmicity. A feedback loop involving the frq, wc-1, and wc-2 gene products (FRQ/ WCC) is an import...
Circadian locomotor rhythms are normal in Ts65Dn "Down syndrome" mice and unaffected by pentylenetetrazole [0.03%]
“唐氏综合征”Ts65Dn鼠的昼夜运动节律正常且不受戊四氮的影响

Norman F Ruby et al.
Ts65Dn mice are used extensively as a model for Down syndrome. Recent studies have reported conflicting evidence as to whether these mice express circadian rhythms. The authors therefore recorded locomotor activity patterns from these anima...

Relations between common nightmares and chronobiological factors remain poorly understood. The possibility that nightmare frequency and distress are associated with chronotype ("morningness-eveningness") was investigated in a sample of resp...

Activity patterns are the product of interactions between an internal circadian clock and direct responses to photic and nonphotic features of the environment that are said to "mask" the influence of that clock. Evolutionary transitions bet...

Arrhythmic rats after SCN lesions and constant light differ in short time scale regulation of locomotor activity [0.03%]
下丘脑视交叉上核损伤和恒定光照引起的无节律大鼠在运动活动短期调节方面存在差异

Circadian rhythm disruption (i.e., arrhythmicity) in motor activity is an abnormal behavioral pattern. In rats, it can be caused by the lesion of the hypothalamic suprachiasmatic nucleus (SCN) and by prolonged exposure to constant light (LL...

Glutamate and GABA neurotransmission from the paraventricular thalamus to the suprachiasmatic nuclei in the rat [0.03%]

The anterior paraventricular thalamus (aPVT) projects to the SCN, and a lesion of the aPVT leads to phase delays of circadian rhythms, instead of advances, produced by light pulses at CT23. As a first step to understanding the underlying me...
