简要总结
This research aims to determine if melatonin supplementation, through improvements in sleep quality, increases the ability to repair oxidative DNA damage and reduce lipid peroxidation levels among nightshift workers.
详细描述
Administering a 3 mg melatonin supplement to nightshift workers prior to day sleep may significantly improve their oxidative DNA damage repair capacity and reduce the occurrence of lipid peroxidation [measured as increased excretion of urinary 8-hydroxydeoxyguanosine (8-OH-dG) and decreased excretion of urinary 8-isoprostane, respectively] through improvements in sleep quality (measured via actigraphy) and melatonin's direct antioxidative properties.
