Evening melatonin and bright light administration induce additive phase shifts in dim light melatonin onset.
In healthy young men, administration of a single light pulse (5000 lux for 3 hr) or a single melatonin pill (5 mg) at 20:40 hr under controlled constant routine conditions of <10 lux, yielded a phase delay and a phase advance, respectively, in the circadian marker of dim light melatonin onset 24 hr later. Phase shifts after combining the two interventions were additive. Melatonin suppression is...
متن کاملIs the Alternative Healthy Eating Index (AHEI) Associated with Depression and Anxiety?
Anxiety and depression are among the mental disorders that are highly prevalent in advanced and developing societies. Statistics show that one in five people, especially women, suffer from these disorders at some point in their lives. In Iran, the prevalence of anxiety is 15.6% and depression is 12.7% (Khademian et al., 2021, Mohammadi et al., 2019)
متن کاملEmotional Eating Phenotype is Associated with Central Dopamine D2 Receptor Binding Independent of Body Mass Index
PET studies have provided mixed evidence regarding central D2/D3 dopamine receptor binding and its relationship with obesity as measured by body mass index (BMI). Other aspects of obesity may be more tightly coupled to the dopaminergic system. We characterized obesity-associated behaviors and determined if these related to central D2 receptor (D2R) specific binding independent of BMI. Twenty-tw...
متن کاملThe hockey-stick method to estimate evening dim light melatonin onset (DLMO) in humans.
The onset of melatonin secretion in the evening is the most reliable and most widely used index of circadian timing in humans. Saliva (or plasma) is usually sampled every 0.5-1 hours under dim-light conditions in the evening 5-6 hours before usual bedtime to assess the dim-light melatonin onset (DLMO). For many years, attempts have been made to find a reliable objective determination of melaton...
متن کاملEffects of light exposure and sleep displacement on dim light melatonin onset.
The purpose of the study was to induce in two different ways, a phase-angle difference between the circadian pacemaker and the imposed sleep-wake cycle in humans, we intended to: (i) shift the circadian pacemaker by exposure to bright light and keep the timing of the sleep-wake cycle fixed; and (ii) keep the timing of the circadian pacemaker fixed by a constant light-dark cycle and displace sle...
