Myopia, Light and Circadian Rhythms
Myopia has been investigated scientifically for over a century but the search for an effective remedy has been manifestly unsuccessful. The prevalence of myopia in developed societies has now risen to about 30% in USA (Vitale, Sperduto et al. 2009) and up to 70% in some Asian centres (Lin, Shih et al. 2004). In addition to the socio-economic burden of providing optical corrections for myopia, c...
متن کاملNeuroimaging, cognition, light and circadian rhythms
In humans, sleep and wakefulness and the associated cognitive processes are regulated through interactions between sleep homeostasis and the circadian system. Chronic disruption of sleep and circadian rhythmicity is common in our society and there is a need for a better understanding of the brain mechanisms regulating sleep, wakefulness and associated cognitive processes. This review summarizes...
متن کاملLight, Sleep, and Circadian Rhythms: Together Again
The 24-hour (h) light–dark (LD) cycle is a fundamental characteristic of Earth’s environment and so its powerful influence on the behaviour and physiology of animals and humans that evolved on this planet is not surprising. In addition to influencing the perception of visual images, light coordinates the temporal rhythms of physiology and behaviour by sending signals to structures in the brain ...
متن کاملInfluence of N-Phthaloyl GABA on the Circadian Rhythms of Lipid Peroxidation and Antioxidants in Wistar Rats under Constant Light
N-Phthaloyl GABA was administrated daily (50 mg/Kg body weight-i.p) to Wistar rats for 21 days and circadian rhythms of thiobarbituric acid reactive substances (TBARS) and antioxidants such as reduced glutathione (GSH), catalase (CAT) and superoxide dismutase (SOD) were studied under constant light (LL) conditions. Delayed acrophase of TBARS and advanced acrophase of antioxidants (GSH, CAT and ...
متن کاملCircadian Rhythms: Influence of Light in Humans
Many aspects of human physiology and behavior are dominated by 24 h rhythms that have a major impact on our health and well-being. For example, sleep– wake cycles, alertness and performance patterns, core body temperature rhythms, and the production of hormones such as melatonin and cortisol are all regulated by an endogenous near-24 h oscillator in the suprachiasmatic nuclei (SCN) of the anter...
