Serotonin, acting in a specific brain region, promotes sleep in fruit flies
Researchers have found that the neurotransmitter serotonin, known to affect many behaviors, also appears to promote lasting, quality sleep in an animal model for understanding how sleep is regulated. While central to the lives of most animals, the proper regulation sleep remains a largely enigmatic process. The findings are reported by Quan Yuan, William Joiner, and Amita Sehgal at the Un...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. The study is publishing online this week in the Proceedings of the National Academy of Science. The study was led by Alfred Lewy, M.D., Ph.D., an internationally recogn...Plutonium or greenhouse gases? Weighing the energy options
Can nuclear energy save us from global warming? Perhaps, but the tradeoffs involved are sobering: thousands of metric tons of nuclear waste generated each year and a greatly increased risk of nuclear weapons proliferation or diversion of nuclear material into terrorists' hands. So concludes University of Michigan professor Rodney Ewing, who has analyzed just how much nuclear power would n...Low levels of neurotransmitter serotonin may perpetuate child abuse across generations
Infant abuse may be perpetuated between generations by changes in the brain induced by early experience, research shows at the University of Chicago shows. A research team found that when baby rhesus monkeys endured high rates of maternal rejection and mild abuse in their first month of life, their brains often produced less serotonin, a chemical that transmits impulses in the brain. Low...To sleep, perchance to dream: New insight into melatonin production
In the April 1 issue of G&D, a Korean research team led by Dr. Kyong-Tai Kim (Pohang University) describes how melatonin production is coordinated with the body's natural sleep/wake cycles. Melatonin is a hormone produced by the pineal gland in the brain, which helps to regulate our bodies' circadian rhythm (the roughly-24-hour cycle around which basic physiological processes proceed)....PROTEINEER sp: Automated Spot Picker from Bruker Daltonics

According to a new study the use of serotonin-raising drugs like antidepressants and slimming pills in combination may trigger a stroke. In common the mecahnism of durgs is by increasing the levels of serotonin, a natural chemical with many different roles in the body.// Examples include diet pills, anti-migraine drugs and some of the newer antidepressants.

The report on the scientific evidence to date for the benefits of melatonin supplements used for disorders due to sleep schedule alterations and primary and secondary sleep disorders were reviwed.// Disorders due to sleep schedule alterations can stem from flying across time zones or working night shifts. Primary sleep disorders, which include insomnia, can be caused by factors such as st...Walnuts a source of the Anti –oxidant Hormone Melatoni
New research has shown that consumption of walnuts can boost blood levels of melatonin and antioxidants in rats. Melatonin is a hormone that is naturally produced in humans by the pineal gland. It is most commonly associated with // inducing and regulating sleep, since it is produced during the hours of darkness. Researchers investigated whether melatonin is present in walnuts, and whe...Calcitonin EIA Bone and Mineral Metabolism 021-SDX017

Description:Calcitonin is synthesized in the parafollicular C-cells of the thyroid gland and is packaged in secretory granules. The major action of calcitonin is to lower plasma calcium concentrations, by inhibiting osteoclast activity, resulting in decreased mobilization of calcium from bone [1]. This effect is most evident in conditions associated with high levels of bone remodeling (e.g. in Pagets disease...Alterations in Intestinal Serotonin in Irritable Bowel Syndrome and Dyspepsia
