By collecting data continuously over 24 hours, accelerometers and other wearable devices can provide novel insights into circadian rhythms and their relationship to human health. Existing approaches for analyzing diurnal patterns using thes...
The Drosophila apterous 56f mutation impairs circadian locomotor activity [0.03%]

We investigated effects of apterous mutation ap56f on circadian locomotor activity, eclosion rhythms, and transcript levels of period and timeless in Drosophila. We investigated circadian locomotor activity and eclosion rhythms in ap 56fand...
Haloperidol, but not olanzapine, may affect expression of PER1 and CRY1 genes in human glioblastoma cell line [0.03%]
氟哌啶醇而非奥氮平可能影响人类胶质母细胞瘤细胞系的PER1和CRY1基因表达

Łukasz Mokros et al.
Background: There is barely any evidence of antipsychotic drugs affecting the molecular clockwork in human, yet it is suggested that clock genes are associated with dopaminergic transmission, i.e. the main target of this therapeutics. We de...

This article reviews various procedures used in the analysis of circadian rhythms at the populational, organismal, cellular and molecular levels. The procedures range from visual inspection of time plots and actograms to several mathematica...
Circadian expressions of cardiac ion channel genes in mouse might be associated with the central clock in the SCN but not the peripheral clock in the heart [0.03%]
小鼠心脏离子通道基因的昼夜表达可能与SCN中的中央时钟相关而非心脏中的外周时钟

Maoqing Tong et al.
Significant circadian variations exist in the frequency of cardiac arrhythmia, but few studies have examined the relation between cardiac ion channels genes and biological clocks. We investigated this relation using suprachiasmatic nuclei l...

Bright light in the blue-green range, administered in the early morning hours (prior to waking) may be particularly effective in shifting circadian rhythms and may increase gonadotropin production. Accordingly, we tested the feasibility and...
Daily oscillation of glutathione redox cycle is dampened in the nutritional vitamin A deficiency [0.03%]
营养性维生素A缺乏会削弱谷胱甘肽红ox的日常波动

Examples of hormonal phase-shifting of circadian gene expression began to emerge a few years ago. Vitamin A fulfills a hormonal function by binding of retinoic acid to its nuclear receptors, RARs and RXRs. We found retinoid- as well as cloc...
The Effects of 24-hour Sleep Deprivation on the Exploration-Exploitation Trade-off [0.03%]
24小时睡眠剥夺对探索与开发的权衡的影响

Sleep deprivation has a complex set of neurological effects that go beyond a mere slowing of mental processes. While cognitive and perceptual impairments in sleep deprived individuals are widespread, some abilities remain intact. In an effo...
A procedure of multiple period searching in unequally spaced time-series with the Lomb-Scargle method [0.03%]
用于不等时间序列的Lomb-Scargle方法多周期搜索程序

H P Van Dongen et al.
Periodogram analysis of unequally spaced time-series, as part of many biological rhythm investigations, is complicated. The mathematical framework is scattered over the literature, and the interpretation of results is often debatable. In th...

With respect to the first example in Schimmel (2001), Van Dongen et al. (2001) conclude from their Lomb-Scargle analysis that the noise I used 'contains new periodicities that are added to the signal (these periodicities by themselves resem...
