Virtual discovery of melatonin receptor ligands to modulate circadian rhythms.
The neuromodulator melatonin synchronizes circadian rhythms and related physiological functions via actions at two G protein-coupled receptors: MT1 and MT2.

Hypothermia Plus Melatonin in Asphyctic Newborns: A Randomized-Controlled Pilot Study.
To investigate the effect of adding melatonin to hypothermia treatment on neurodevelopmental outcomes in asphyctic newborns.

Melatonin a Promising Candidate for DNA Double-Stranded Breaks Reduction in Patients Undergoing Abdomen-Pelvis Computed Tomography Examinations.
Cancer incidence is 24% greater in children and young adults exposed to Computed Tomography (CT) scans than those unexposed. Non-repair of ionizing radiation-induced DNA double-Strand Breaks (DSBs) can initiate carcinogenesis. In the present study, we aimed to investigate the radioprotective potential of melatonin against DSBs in peripheral blood lymphocytes of patients undergoing the abdomen-pelvis CT…

Effectiveness of Complementary and Alternative Medicine Interventions for Sleep Quality in Adult Intensive Care Patients: A Systematic Review.
Pharmacological interventions for sleep (analgesic, sedative and hypnotic agents) can both disrupt and induce sleep and have many negative side effects within the intensive care population. The use of complementary and alternative medicine therapies to assist with sleep has been studied but given the variety of modalities and methodological limitations no reliable conclusions have been…

Daytime melatonin levels in saliva are associated with inflammatory markers and anxiety disorders.
The bidirectional interaction between melatonin and the immune system has largely gone unexplored in a clinical context and especially in a psychiatric population. This study explored the association between melatonin during the day and inflammatory cytokines in young adult patients seeking psychiatric care.

Short Sleep Is Associated With Low Bone Mineral Density and Osteoporosis in the Women’s Health Initiative.
Short sleep duration, recognized as a public health epidemic, is associated with adverse health conditions, yet little is known about the association between sleep and bone health. We tested the associations of usual sleep behavior and bone mineral density (BMD) and osteoporosis.

Circadian rhythm and its association with birth and infant outcomes: research protocol of a prospective cohort study.
Circadian rhythm plays an important role as our internal body's clock that synchronizes behavior and physiology according to the external 24-h light-dark cycle. Past studies have associated disrupted circadian rhythm with higher risk of miscarriages, preterm birth and low birth weights. This paper described the protocol of a prospective cohort study which aims to determine…

Effect of Melatonin Supplementation in Combination With Neoadjuvant Chemotherapy to miR-210 and CD44 Expression and Clinical Response Improvement in Locally Advanced Oral Squamous Cell Carcinoma: A Randomized Controlled Trial.
Squamous cell carcinoma of the oral cavity (OSCC) is the sixth most common malignancy. Surgery is mainstay treatment for oral cancers. Surgery in locally advanced OSCC presents many challenges primarily because the head and neck have critical structures that can be damaged by tumor or treatment.

Melatonin in the treatment of fibromyalgia symptoms: A systematic review.
The available pharmacological modalities for the treatment of fibromyalgia (FM) are associated with a variety of adverse effects and limited benefits. In this study, we systematically reviewed the impact of melatonin in the treatment of FM.

Melatonin and Parkinson Disease: Current Status and Future Perspectives for Molecular Mechanisms.
Parkinson disease (PD) is a chronic and neurodegenerative disease with motor and nonmotor symptoms. Multiple pathways are involved in the pathophysiology of PD, including apoptosis, autophagy, oxidative stress, inflammation, α-synuclein aggregation, and changes in the neurotransmitters.

Influence of Dietary Sources of Melatonin on Sleep Quality: A Review.
Sleep is an essential biological phenomenon, being a physiological and behavioral process necessary for quality of life. Melatonin is a circadian hormone produced at night by the pineal gland, regulated by the light/dark cycle, under the control of the suprachiasmatic nucleus. Melatonin is an indoleamine, synthesized from the essential amino acid tryptophan via serotonin. Melatonin…

New awakenings: current understanding of sleep dysfunction and its treatment in Parkinson’s disease.
The non-motor features of Parkinson's disease (PD) are increasingly being recognised. This review deals with the spectrum of sleep disorders associated with PD, which have a multifactorial aetiology and can significantly have an impact on the quality of life of patients and their carers.

Impact of Sleep Disorder as a Risk Factor for Dementia in Men and Women.
Sleep is an essential physiological process, especially for proper brain function through the formation of new pathways and processing information and cognition. Therefore, when sleep is insufficient, this can result in pathophysiologic conditions.
