No evidence that melatonin is effective in treating jet lag
There is no evidence that melatonin is effective in treating secondary sleep disorders or preventing jet lag, finds a study published online by the BMJ today. view more (2006-02-10)
Salivary melatonin may decrease periodontal disease severity according to new study findings
Salivary melatonin may play an important role in maintaining periodontal health, according to a new study published in the Journal of Periodontology. view more (2006-09-13)
Use public funds to test jet lag drug, say researchers
The hormone melatonin has long been used to prevent and treat jet lag, but in many countries it cannot be sold because it is not licensed. Researchers in this week's BMJ argue that if use of the drug is in the public interest, then public funds should be used to get it adequately tested to be licensed. Jet lag is caused by the disturbance of... view more... (2003-02-05)
Melatonin may save eyesight in inflammatory disease
Current research suggests that melatonin therapy may help treat uveitis, a common inflammatory eye disease. The related report by Sande et al., "Therapeutic Effect of Melatonin in Experimental Uveitis," appears in the December issue of The American Journal of Pathology. view more (2008-11-24)
Hormone irregularities linked to chronic migraine
Hormonal irregularities may explain why migraine becomes chronic, shows research in the Journal of Neurology Neurosurgery and Psychiatry. Around 3 per cent of the population are chronic migraineurs, suffering pounding headaches for around 15 days a month. Hourly blood samples were taken from 17 chronic migraine sufferers, three of whom were men.... view more... (2001-11-23)
Melatonin may be served as a potential anti-fibrotic drug
In China, the incidence of liver cirrhosis is still high. Liver cirrhosis results from fibrosis. If treated properly at fibrosis stage, cirrhosis can be prevented. view more (2009-03-31)
What effect does melatonin have in colitis?
In rats with experimental colitis, the marked increase in bacterial translocation in postcolitis rats has been reversed by melatonin administration. This is due to melatonin's anti-inflammatory and anti-apoptotic effects. view more (2008-03-18)
Hormone treatment eases post-surgery distress in children
A scary unknown for many children, the prospect of surgery can cause intense preoperative anxiety. view more (2009-07-02)
Melatonin improves mood in winter depression
Researchers at Oregon Health & Science University(OHSU) have found that melatonin, a naturally occurring brain substance, can relieve the doldrums of winter depression, also known as seasonal affective disorder, or SAD. view more (2006-05-02)
Melatonin is an effective treatment for sleep problems in children with autism
A study in the April 15 issue of the Journal of Clinical Sleep Medicine determined that over-the-counter melatonin medication can shorted the length of time it takes for children with autistic spectrum disorder (ASD), Fragile X Syndrome (FXS), or both to fall asleep at the beginning of the night. view more (2009-04-15)
IVF women more fertile in lighter months
Researchers have found that pregnancy from IVF is more likely between May and September, probably due to biological programming that we have inherited from our primate origins. The British Fertility Society hear today how investigators from IVF clinics in Liverpool and Chester discovered that not only were significantly less drugs required to... view more... (2004-03-31)
Cicardian system suffers and protects from prenatal cocaine exposure
Researchers from Boston University School of Medicine (BUSM) have shown that prenatal cocaine exposure in zebrafish (which share the majority of the same genes with humans) can alter neuronal development and acutely dysregulate the expression of circadian genes and those affecting melatonin signaling, growth and neurotransmission. view more (2007-07-11)
Genes, brain chemistry may dictate nicotine cravings, says CU-Boulder study
Individual brain chemistry and genes could be key to understanding why some people become addicted to nicotine and why the chemical compound's effects appear to diminish at night. view more (2007-11-07)
Melatonin Most Effective For Sleep When Taken For Off-Hour Sleeping
Researchers from the Divisions of Sleep Medicine at Brigham and Women's Hospital and Harvard Medical School have found in a double-blind placebo-controlled clinical study, that melatonin, taken orally during non-typical sleep times, significantly improves an individual's ability to sleep. view more (2006-05-01)
Discovery of new gene associated with diabetes risk suggests link with body clock
A connection between the body clock and abnormalities in metabolism and diabetes has been suggested in new research by an international team involving the University of Oxford, the Wellcome Trust Sanger Institute and the MRC Epidemiology Unit in Cambridge. view more (2008-12-08)
Study demonstrates role of exercise in modifying melatonin levels
Moderate physical activity, which is believed to help reduce the risk of breast cancer, may do so because it increases production of a hormone believed to have protective effects against the disease, a Canadian research team has learned. view more (2005-12-02)
The hormone of darkness: melatonin could hurt memory formation at night
What do you do when a naturally occurring hormone in your body turns against you? What do you do when that same hormone - melatonin - is a popular supplement you take to help you sleep? A University of Houston professor and his team of researchers may have some answers. view more (2007-11-16)
New synthetic compounds appear to prevent brain cell death
Spanish chemists have developed a promising set of synthetic compounds that one day could help slow or perhaps halt the progression of Alzheimer's disease and other neurological disorders. view more (2005-12-21)
Increase in childhood leukaemia may be part due to increased light at night
London, UK: International experts will (Wednesday 8 September) consider the evidence for a link between the rise in childhood leukaemia and increased light at night at an international scientific conference in London. The incidence of childhood leukaemia increased dramatically in the twentieth century. The increase has mainly affected the under... view more... (2004-09-06)
