Sleep disturbances and sensory sensitivities are common disabling features of autism, but their underlying causes are not clear. We hypothesize that both of these difficulties reflect disrupted communication between a deep brain structure, the thalamus, and the brain's outer layer, the cortex. This communication is mediated by the thalamic reticular nucleus (TRN). Due to its small size and location deep in the brain, we cannot assess TRN function without invasive techniques. Fortunately, sleep spindles, a specific brain rhythm provide a noninvasive read-out of TRN function. In Aim 1 we will ex…

People who have insomnia typically co-occur with mental disorders, especially anxiety and depression. It has been documented that the melatonin phase in the depressed patients was reached with a delay. Melatonin plays a crucial role in regulation of circadian-clock-related gene expression.

Sleep problems can lead to a bad quality of life and a raise of morbidity, also in dialysis patients. Sleep problems can be caused by a disturbance of circadian rhythms in our body. For a good regulation of these circadian rhythms a uniform external synchronisation is necessary. This is the synchronisation of the biological clock of our body by light and other influences. In case of a disturbance of the external synchronisation, due to for example naps during the day or wake periods at night, internal rhythms can be unlinked. As a result a weakened melatonin rhythm and a problematic sleep-wake…

Our long term hypothesis is that giving premature infants breast milk that was pumped during the night and has high concentration of melatonin will improve outcome of several clinical conditions related to premature infants. Prior to testing this, we need to learn the pharmacokinetics of melatonin in vitro. In this preliminary research we would like to check the levels of melatonin in breast milk pumped during the night, and evaluate the rate of degradation of the melatonin to determine the half life of melatonin in pumped breast milk (in vitro).

The circadian rhythm, the sleep-wake cycle, is mainly regulated by melatonin. The synthesis of melatonin is stimulated by the absence of light, leading to peak serum levels before bedtime. In humans, this endogenous "signaling" neurohormone induces sleep. Exogenous melatonin can be beneficial in different sleep disturbances including delayed sleep phase insomnia, melatonin- deficiency-related insomnia (especially in elderly) and shift work sleep disorder. Melatonin is known for its low and variable bioavailability in humans due to a high first pass effect and variable pharmacokinetics and shor…

RATIONALE: Radiation therapy uses high-energy x-rays to damage tumor cells. Drugs such as melatonin may make tumor cells more sensitive to radiation therapy and may protect normal cells from the side effects of radiation therapy. PURPOSE: Randomized phase II trial to determine the effectiveness of combining melatonin with radiation therapy in treating patients who have brain metastases.

This protocol is a multicenter clinical trial of melatonin for sleep disturbances associated with Alzheimer's disease (AD). Frequent nocturnal awakening is a common behavioral symptom of AD. Nighttime wandering and agitated behavior may result in injuries and sleep disruption for caregivers. Alternatives are sorely needed to the currently available sleep medications that have marginal efficacy and serious side effects. Melatonin is a naturally occurring hormone secreted by the pineal gland. It has soporific effects with oral administration and is well tolerated. It enhances sleep in normal old…

The subjects will be stratified according to treatment duration (less than 3 weeks; equal to or greater than 3 weeks) and prior chemotherapy.

Neurocognitive sequelae observed in preterm represent a major health problem for which there is no preventive treatment approved to date. These effects are the result of a multifactorial brain damage occurring in developing prenatal and perinatal period. Melatonin, the principal hormone secreted by the pineal gland has neuroprotective properties in various experimental animal models of perinatal brain damage level. This hormone readily crosses the placental barrier, its antenatal administration would have a neuroprotective effect in the case of preventive preterm birth before 28 weeks of ameno…

Delirium in older patients is associated with increased mortality and health care costs. And delirium is frequent in intensive care unit (ICU). Circadian rhythm alteration is one of the most important risk factor for developing delirium.

Randomly selected patients of the melatonin group are given 5mg of melatonin in the evening from the day before surgery to the the 5th postoperation day. In contrast, patients in the control group are given placebo. Prima…

During the birth process certain conditions can cause oxygen delivery and/or blood flow to the baby's brain to become interrupted. This can cause permanent brain damage. Brain damage occurs in two phases. The first occurs at the time of injury when brain cells in the affected area 'die'. There is nothing that can be done about this. The second phase of injury occurs over the next few days. This second phase is caused by inflammation and release of toxic chemicals from the injured site. Cooling the baby to a temperature of 92.5° F, for 3 days has been shown to reduce the second phase of injury …

Treatment of disseminated melanoma is still a difficult issue. Obvious achievements of recent years proves efficacy of immunologic approachees in this field. The ability of melatonin and metformin to decrease metabolic immunosuppression was shown in many experimental studies. Some literature data confirm the possibility of increasing efficacy of melatonin with dacarbazine (DTIC) and metformin with DTIC combinations. We hypothesized that this combinations could be more effective than DTIC monotherapy in terms of response rate and time to progression.

Background: Experimental studies have documented the beneficial effects of the endogenously produced antioxidant, melatonin, in reducing tissue damage and limiting cardiac pathophysiology in models of experimental ischemia-reperfusion. Melatonin confers cardioprotection against ischemia-reperfusion injury most likely through its direct free radical scavenging activities and its indirect actions in stimulating antioxidant enzymes. These actions of melatonin permit it to reduce molecular damage and limit infarct size in experimental models of transient ischemia and subsequent reperfusion. Study…

During each session, MEL (5mg) , MEL (8mg) or placebo were ingested, in a randomized order, before nocturnal sleep. The next morning (08:00h), participants performed the following psycho-cognitive and physical tests: Hooper's index, reaction time, vigilance, handgrip strength , s…

Lennox-Gastaut syndrome is a severe epileptic encephalopathy of childhood. In that syndrome, various type of seizure occur, mainly tonic seizures, atonic seizures and atypical absences. The tonic seizure occur mostly at night. The hypothesis is that the melatonin could have a positive effect in that syndrome, by reducing the epileptic activity (assessed in the polysomnographic record by counting the number of interictal and ictal discharges) and stabilizing the structure of sleep. The study is double blind, randomised, cross-over designed.

The purpose of this study is to investigate the effect of 6 mg melatonin daily for 1 week preoperatively to 12 weeks postoperatively on depressive symptoms, anxiety, cognitive function and sleep disturbances in breast cancer patients.

Therefore, the present study aims at investigating whether inositol and melatonin are able to improve the number of oocytes obtained after ovarian stimulation with Recombinant Follicle Stimula…

Ulcerative colitis is an inflammatory bowel disease that afflicts up to one million people in the U.S. Symptoms include rectal urgency, bloody diarrhea, moderate to severe abdominal pain, fever, and fatigue. Melatonin is a hormone that is associated with sleep and other body functions that may be related to health. Melatonin is produced in the pineal gland and, in fact, it is produced in even greater amounts in the gut. Melatonin appears to be important in gastrointestinal tract physiology and health, and data from cell and animal experiments, and some studies in humans, suggest that supplemen…

The primary aim of this proposal is to present a novel, multimodal treatment strategy for increasing lean body mass in individuals with cancer who experience cachexia between baseline and day 29 (+/- 3 days). The strategy includes graded resistance training and aerobic exercise, targeted nutrient supplementation and pharmacologic intervention (melatonin). We postulate that this strategy, together with the simultaneous management of symptoms that decrease appetite (e.g. depression, pain, and nausea), will also accomplish our secondary objectives of improving clinical outcomes such as strength …

The primary focus of this five-year study will be to optimize the melatonin dosing regimen for synchronizing the body clocks of elderly blind individuals to the 24-hour day.

In many mammals, the duration of the nocturnal melatonin elevation regulates seasonal changes in reproductive hormones such as luteinizing hormone (LH). Melatonin's effects on human reproductive endocrinology are uncertain. It is thought that the same hypothalamic pulse generator may both trigger the pulsatile release of GnRH and LH and also cause hot flashes. Thus, if melatonin suppressed this pulse generator in postmenopausal women, it might moderate hot flashes. This clinical trial tested the hypothesis that melatonin could suppress LH and relieve hot flashes.

Primary Objective: To evaluate the impact of postoperative exogenous nocturnal melatonin supplementation on the early regulation of the sleep-wake cycle and its clinical impact (subjective improvement of the quality of sleep and reduction of cardiopulmonary events) during the first postoperative week following anesthesia and surgery in older breast cancer patients receiving a unilateral segmental mastectomy with or without intraoperative lymph node mapping, sentinel node biopsy and axillary node dissection. Secondary Objective: To collect data and validate the Postoperative Srejic Sleep SAT…

Oxidative stress is one of the main mechanisms causing harm in severe infection with septic shock, ischemia-reperfusion injury in resuscitated cardiac arrest and ischemic and hemorrhagic stroke. Melatonin is a potent scavenger of the mediators of oxidative stress, oxygen and nitrogen-reactive species, which directly injure cell structures like walls and DNA and thus cause organ dysfunction. In a previous study we have observed that high-dose oral bedtime melatonin (OBM) is associated with improved organ function in severe Covid-19 patients

Oral Melatonin is a commercially available product available alone and as a constituent in a number of supplements. Previous research suggests that short-term supplementation with oral melatonin may amplify the recovery response to damaging resistance exercise via modulation of subsequent immune and inflammatory responses. However the effects of oral melatonin on neutrophil and monocyte invasion/migration, a critical step in the resolution of skeletal muscle tissue homeostasis, has not been examined. An oral melatonin supplement (5mg) will be provided three times daily beginning 24-hours befor…

Melatonin has been shown to prevent cellular damage produced by oxidative stress or in situations of ischaemia, inhibiting the synthesis of oxidants and pro inflammatory factors such as pro-inflammatory cytokines, substances which are present in pressure ulcers and can affect the healing process, slowing it down. Melatonin gel has also been shown to prevent ulcers in the oral mucosa due to radiotherapy. Therefore, the hypothesis for this study is that the melatonin cream provides greater ulcer area reduction than standard pressure ulcer treatment.

Treatment with melatonin is often initiated on an insufficient basis as it has not been established prior to starting the treatment whether or not the child had delayed release of endogenous melatonin. At the clinic, it has furthermore been observed that the length of time a child experiences an effect of melatonin treatment varies substantially. In a clinical context, treatment with melatonin is used increasingly (www.Medstat.dk). However, there is no tradition in Denmark for measuring the endogenous melatonin level before initiating such treatment. Hence there is no way of knowing to what e…
