Abstract:
Circadian regulation of kidney function is involved in maintaining whole body homeostasis, and dysfunctional circadian rhythm can potentially be involved in disease development. Magnetic resonance imaging (MRI) provides reliable and reproducible repetitive estimates of kidney function noninvasively without the risk of adverse events associated with contrast agents and ionizing radiation. The purpose of this study was to estimate circadian variations in kidney function in healthy human subjects with MRI and to relate the findings to urinary excretions of electrolytes and markers of kidney funct

Abstract:
Background: Circadian regulation of sleep, cognition, and metabolic state is driven by a central clock, which is in turn entrained by environmental signals. Understanding the circadian regulation of mood, which is vital for coping with day-to-day needs, requires large datasets and has classically utilised subjective reporting. Methods: In this study, we use a massive dataset of over 800 million Twitter messages collected over 4 years in the United Kingdom. We extract robust signals of the changes that happened during the course of the day in the collective expression of emotions and fatigue. W

Abstract:
CRYPTOCHROMES (CRYs) are structurally related to ultraviolet (UV)/blue-sensitive DNA repair enzymes called photolyases but lack the ability to repair pyrimidine dimers generated by UV exposure. First identified in plants, CRYs have proven to be involved in light detection and various light-dependent processes in a broad range of organisms. In Drosophila, CRY’s best understood role is the cell-autonomous synchronization of circadian clocks. However, CRY also contributes to the amplitude of circadian oscillations in a light-independent manner, controls arousal and UV avoidance, influences visual

Abstract:
The human sleep-wake cycle is generated by a circadian process, originating from the suprachiasmatic nuclei, in interaction with a separate oscillatory process: the sleep homeostat. The sleep-wake cycle is normally timed to occur at a specific phase relative to the external cycle of light-dark exposure. It is also timed at a specific phase relative to internal circadian rhythms, such as the pineal melatonin rhythm, the circadian sleep-wake propensity rhythm, and the rhythm of responsiveness of the circadian pacemaker to light. Variations in these internal and external phase relationships, such

Abstract:
AbstractCircadian rhythms are the changes in biological processes that occur on a daily basis. Among these processes are reactions involved in metabolic homeostasis. Circadian rhythms are structured by the central clock in the suprachiasmatic nucleus of the hypothalamus via the control of melatonin expression. Circadian rhythms are also controlled by the peripheral clocks, which are intracellular mechanisms composed of the clock genes, whose expression follows a circadian pattern. Circadian rhythms are impacted by signals from the environment called zeitgebers, or time givers, which include li

Abstract:
Over the past decades, decision making under risk has garnered a great amount of attention both in the field of economics and psychology. Although state-dependent variabilities of risk taking are well-documented, little is known about the effects of a person’s preferred time of day, or chronotype, in risky decision making. Under circumstances of circadian mismatch (e.g., when an “early bird” makes decisions in the evening), research suggests that decision making may reflect a greater reliance on heuristics, such as using stereotypes in social judgments. However, the effects of circadian mismat

Abstract:
The genetic architecture of placental abruption (PA) remains poorly understood. We examined variations in SNPs of circadian clock-related genes in placenta with PA risk. We also explored placental and maternal genomic contributions to PA risk. Placental genomic DNA samples were isolated from 280 PA cases and 244 controls. Genotyping was performed using the Illumina Cardio-MetaboChip. We examined 116 SNPs in 13 genes known to moderate circadian rhythms. Logistic regression models were fit to estimate odds ratios (ORs). The combined effect of multiple SNPs on PA risk was estimated using a weight

Abstract:
Circadian rhythms are daily internal predictive biological cycles. Numerous studies have associated human circadian gene polymorphisms with phenotypic changes and multiple disease risks. Subsequent replications have often been negative in other populations, possibly due to poor linkage disequilibrium (LD) between the reported single nucleotide polymorphisms (SNPs) and underlying phenomena, or differing LD across populations. Alternatively, non-human circadian studies have reported population- specific effects, often expressed as latitudinal dines. Genome-wide genotyping results can produce dis

Abstract:
Although there is strong evidence for a genetic contribution to inter-individual variations in sleep, the underlying factors and their interaction remain largely elusive. Much effort has been expended in studying genetic variations contributing to circadian and sleep phenotypes, the individual pattern of the human sleep EEG, reactions to sleep loss, and the pathophysiology of sleep-related disorders. Certain sleep-related diseases may be caused by single genes, while the etiology of others seems to be variable and complex. This is especially the case when the immune system is involved. This ch

The majority of molecular, physiological, and behavioural processes undergo substantial variations across a 24 h period. The health implications of such fluctuations, whether they are expressions of an intrinsic circadian rhythmicity or are secondary to changes in physical activity, posture, and/or sleep, are increasingly recognized. Similar to other biological functions, the cardiovascular system exhibits a prominent day–night profile, with profound haemodynamic, autonomic, and hormonal oscillations occurring during the sleep period.
