Melatonin News and Research RSS Feed - Melatonin News and Research

Melatonin, also known chemically as N-acetyl-5-methoxytryptamine, is a naturally occurring compound found in animals, plants, and microbes. In animals, circulating levels of the hormone melatonin vary in a daily cycle, thereby allowing the entrainment of the circadian rhythms of several biological functions.

Scientists study how artificial light influences biological clock

Scientists study how artificial light influences biological clock

Researchers at Inserm, led by Claude Gronfier (Inserm Unit 846: Stem Cell and Brain Institute), have, for the first time, conducted a study under real conditions on the body clocks of members of the international polar research station Concordia. [More]
Melatonin has protective effects on traumatic brain injury-induced cerebral cortex

Melatonin has protective effects on traumatic brain injury-induced cerebral cortex

Traumatic brain injury can cause post-traumatic neurodegenerations with an increase in reactive oxygen species and reactive oxygen species-mediated lipid peroxidation. Melatonin, a non-enzymatic antioxidant and neuroprotective agent, has been shown to counteract oxidative stress-induced pathophysiologic conditions like cerebral ischemia/reperfusion injury, neuronal excitotoxicity and chronic inflammation.

Exposure to light at night renders breast cancer completely resistant to drug

Exposure to light at night, which shuts off nighttime production of the hormone melatonin, renders breast cancer completely resistant to tamoxifen, a widely used breast cancer drug, says a new study by Tulane University School of Medicine cancer researchers. [More]

Study investigates possible links between sleep and omega-3 DHA fatty acid status in healthy children

A randomised placebo-controlled study by the University of Oxford suggests that higher levels of omega-3 DHA, the group of long-chain fatty acids found in algae and seafood, are associated with better sleep. [More]
Tips to ease daylight saving time transition

Tips to ease daylight saving time transition

Daylight saving time begins at 2 a.m. on Sunday, March 9, bringing more sunshine in the evenings at the price of an hour of sleep. Vanderbilt Sleep Disorders Center specialist Kelly Brown, M.D., says a little extra planning can alleviate that groggy feeling that often accompanies the time change. [More]
