, 2001 Melatonin yaklaşık 50 yıl önce keşfedilmiş olup ve son yıllarda önemi daha çok anlaşılmış pineal bezden salınan bir hormondur. Vücut sıvılarındaki düzeyi gece maksimum düzeyde artarken, gündüz düşer. Yüksek diffüzyon yeteneği ve lipofilik yapısından dolayı mükemmel bir antioksidan olup, bilinen diğer antioksidanlardan daha güçlüdür.

Automating AI Discovery for Biomedicine Through Knowledge Graphs and Large Language Models Agents
Advanced Intelligent Discovery, EarlyView.This work proposes a novel framework that automates biomedical discovery by integrating knowledge graphs with multiagent large language models. A biologically aligned graph exploration strategy identifies hidden pathways between biomedical entities, and specialized agents use this pathway to iteratively design AI predictors and wet‐lab validation ...

Antioxidants, 2022 Gibberellic acid (GA) was recently shown to induce melatonin synthesis in rice. Here, we examined whether brassinosteroids (BRs) also induce melatonin synthesis because BRs and GA show redundancy in many functions. Among several plant hormones, exogenous

Dialogues in Clinical Neuroscience, 2002 Melatonin (MEL) is a hormone synthesized and secreted by the pineal gland deep within the brain in response to photoperiodic cues relayed from the retina via an endogenous circadian oscillator within the suprachiasmatic nucleus in the hypothalamus. The circadian rhythm of melatonin production and release, characterized by nocturnal activity and daytime

Melatonin Levels in 89 Individuals With Smith Magenis Syndrome
American Journal of Medical Genetics Part A, EarlyView.ABSTRACT In patients with Smith–Magenis syndrome (SMS), an inverted circadian rhythm of melatonin (MT) contributes to the sleep disturbance. Standard treatment of sleep disturbance with MT often leads to extremely high daytime MT levels, resulting in even more sleep disorders. We therefore retrospectively evaluated the MT data of 89 SMS patients.

Melatonin, immune function and cancer [PDF]
, 2011 Melatonin is a natural substance ubiquitous in distribution and present in almost all species ranging from unicellular organisms to humans. In mammals, melatonin is synthesized not only in the pineal gland but also in many other parts of the body ...

American Journal of Medical Genetics Part A, EarlyView.ABSTRACT Smith–Magenis syndrome (SMS) results from either a recurrent 17p11.2 deletion or pathogenic variants in the retinoic acid induced 1 gene (RAI1). While neurodevelopmental impairment and behavioral dysregulation are well recognized, systematic genotype‐stratified analyses across psychiatric domains remain limited.
