The Intersection of Cultural Characteristics and Genetics on the Prevalence of Delayed Sleep Phase Syndrome in Brazilian and Japanese Adults

Apr 2020 DOI 10.14302/issn.2574-4518.jsdr-20-3161
Karim SedkyCorresponding author

Delayed sleep phase syndrome (DSPS) is a circadian rhythm disorder where individuals experience difficulty modifying the time they go to sleep and wake up in response to environmental changes. The circadian rhythm itself is regulated by a variety of clock genes, and various other genes (e.g., AA-NAT…

The Pineal Hypothesis for Drug Dependence

Dec 2018 DOI 10.14302/issn.2578-8590.ipj-18-2524
Francesco CrespiCorresponding author

The pineal gland constitutes a major neuroendocrine organ in the brain. By mean of its neurohormone melatonin it transduces exogenous signals such as circadian and seasonal variations of light and temperature into proper hormonal changes which adjust and adapt internal endocrine functions. Alteratio…

The Effects of Physical Activity on Sleep among Adolescents and Adults: A Narrative Review

May 2018 DOI 10.14302/issn.2574-4518.jsdr-18-2065
Sophie DesjardinsCorresponding author

Objective: Examining the correlation between physical activity measures and sleep in normal adolescents and adult population.

Diurnal Variation in the Core Interthreshold Zone in Women and its Sex Difference

Apr 2018 DOI 10.14302/issn.2578-8590.ipj-18-2078
Naoshi KakitsubaCorresponding author

Background: The core interthreshold zone (CIZ) is defined as the range between core temperature (Tc) at the onset of shivering and the Tc at the onset of sweating under consistent mean skin temperatures of 28°C to 30°C. A previous study demonstrated a diurnal change in the CIZ for male subjects and…

Evaluating Circadian Oscillators in Cancer Stem Cells

Jun 2015 DOI 10.14302/issn.2574-4372.jesr-14-607
Michael E. GeuszCorresponding author

Cancer is influenced by the ability of cells to maintain circadian rhythms in molecular and metabolic processes. Disturbance of the underlying circadian timing mechanism in circadian clock cells leads to a higher frequency and more rapid progression of cancer. Cancer stem cells with properties of em…
