Persistence of < em > clock < /em > gene expression in peripheral blood in dogs maintained under different photoperiod schedules
Chronobiol Int. 2024 Feb 7:1-9. doi: 10.1080/07420528.2024.2315217. Online ahead of print.ABSTRACTDogs are the common pets adopted by humans, and their circadian behavior and physiology are influenced by human habits. In many families, there is a change of lifestyle with respect to the natural daylight (NDL) cycle. Exposure to constant light disrupts some central and peripheral circadian rhythms. The aim of the present study was to improve the knowledge about the circadian changes of clock components in the peripheral blood in dogs housed under NDL and constant light (LL) conditions. Blood samples were collected on five fe...

Circadian modulation of the time course of automatic and controlled semantic processing
Chronobiol Int. 2024 Feb 5:1-15. doi: 10.1080/07420528.2024.2312806. Online ahead of print.ABSTRACTWe investigated whether chronotype and time-of-day modulate the time course of automatic and controlled semantic processing. Participants performed a category semantic priming task at either the optimal or non-optimal time of day. We varied the prime-target onset asynchrony (100-, 450-, 650-, and 850-ms SOAs) and kept the percentage of unrelated targets constant at 80%. Automatic processing was expected with the short SOA, and controlled processing with longer SOAs. Intermediate-types (Experiment 1) verified that our task was...

Early chronotype favors appetite and reduced later day caloric intake among adults with obesity
Chronobiol Int. 2024 Feb 5:1-12. doi: 10.1080/07420528.2024.2313643. Online ahead of print.ABSTRACTLate chronotype (LC) is related to obesity and altered food intake throughout the day. But whether appetite perception and gut hormones differ among chronotypes is unclear. Thus, we examined if early chronotype (EC) have different appetite responses in relation to food intake than LC. Adults with obesity were categorized using the Morningness-Eveningness Questionnaire (MEQ) as either EC (n = 21, 18F, MEQ = 63.9 ± 1.0, 53.7 ± 1.2 yr, 36.2 ± 1.1 kg/m2) and LC (n = 28, 24F, MEQ = 47.2 ± 1.5, 55.7 ± 1.4 yr, 37.1 ± 1.0 kg/m2...

The role of social support in the relation between chronotype and mental health in a cohort of women from the American Heart Association Go Red for Women Strategically Focused Research Network
This study evaluates cross-sectional associations between chronotype and mental health, while assessing the mediating role of social support among women from diverse racial/ethnic backgrounds. Women from the American Heart Association Go Red for Women Research Network were included (N = 506, mean age = 37 ± 15.7, 61% racial/ethnic minority). Chronotype, depression, perceived stress, health-related quality of life, and social support were assessed at baseline using validated self-reported questionnaires. Linear regression and causal mediation analyses were performed. Depression and negative emotionality were higher among w...

Hemodialysis-induced chronodisruption and chronotype distribution in patients with chronic kidney disease
This study aimed to investigate the existence of hemodialysis-induced chronodisruption, the chronotype distribution, and their association with sleep quality and quality of life (QoL). This was a cross-sectional study that enrolled 165 patients (mean age: 51.1 ± 12.5 y, 60.6% male) undergoing hemodialysis from three local units. The following instruments were used: the Morning-Eveningness Questionnaire (MEQ); a modified version of the Munich Chronotype Questionnaire (MCQT) to estimate hemodialysis-induced chronodisruption (HIC); the Kidney Disease QoL Short Form (KDQOL-SF); the Epworth Sleepiness Scale (ESS); the Pittsbur...

Lighting the way: Exploring diurnal physical performance differences in school-aged visually impaired children and adolescents
This study aimed to explore the influence of disturbed circadian rhythms on short-term maximal physical performance in children and adolescents with visual impairment. Forty-five volunteers participated in this study, comprising 17 blind, 13 visually impaired, and 15 sighted participants. The participants underwent a series of tests assessing maximal isometric strength performance across two days. To mitigate the influence of morning session fatigue on the evening results, each participant group performed in two separate testing sessions (i.e. in the morning (7:00 h) and in the evening (17:00 h)) on non-consecutive days in...

A pilot study on the expression of circadian clock genes in the alveolar bone of mice with periodontitis
In conclusion, the mRNA transcriptional level of Bmal1, Per2, and Cry1 in alveolar bone of normal mice has circadian rhythm, but the rhythm disappears under the condition of periodontitis, and the cause of its occurrence may be related to inflammatory cytokines.PMID:38275089 | DOI:10.1080/07420528.2024.2305212 (Source: Chronobiology International)

Administration of blue light in the morning and no blue-ray light in the evening improves the circadian functions of non-24-hour shift workers
In this study, we investigate the effects of a simulated non-24-hour military shift work schedule on daily rhythms and sleep, and establish an intervention measure to restore the circadian functions of non-24-hour shift workers. The three stages of experiments were conducted. The stage-one experiment was to establish a comprehensive evaluation index of the circadian rhythms and sleep for all 60 participants by analyzing wristwatch-recorded physiological parameters and sleep. The stage-two experiment evaluated the effects of an intervention strategy on physiological rhythms and sleep. The stage-three experiment was to exami...

Diurnal rhythm of temporal reproduction in the visual field
In this study, we examined the diurnal variations in temporal reproduction around 2-3 seconds with different stimulus eccentricities. Eighteen female participants completed a visual temporal reproduction task at nine time points throughout the day. The results showed significant interactions between clock time and duration, implying diurnal rhythmic variations in temporal reproduction. The reproduction of shorter duration (1500 ms) was overestimated with its highest accuracy in the morning, while the reproduction of longer duration (4500 ms) was underestimated with an approximate 3-hour advancement in acrophase than the sh...

Effects of high and low temperatures on the rhythmic patterns in pit-building behavior of antlion larvae
Chronobiol Int. 2024 Jan 14:1-11. doi: 10.1080/07420528.2024.2303977. Online ahead of print.ABSTRACTTemperature influences the survival, growth, and development of insects including the antlion. In the present study, we examined the 24-h rhythm in the pit-building behavior of the antlion larvae at three different temperature conditions, high (37°C), low (17°C), and room temperature (Control: 25.9 ± 0.2°C). We recorded pit-building activities by monitoring two variables: the Time Lag for the Initiation of Pit Reconstruction (TLIPR) after the demolition of the pit, and the Total Time for Pit Construction (TTPC).

The associations between different types of infections and circadian preference and shift work
In conclusion, neither circadian preference nor shift work seemed to be strongly associated with risk of infections, except for venereal disease (more common in evening types) and influenza-like illness (more common in night workers).
