Melatonin plays important roles in various aspects of biological processes. However, it is less known on the effects and mechanism of melatonin on the postharvest physiological deterioration (PPD) process of cassava, which largely restricts the potential of cassava as a food and industrial crop. In this study, we found that exogenous application of melatonin significantly delayed PPD of cassava...

BACKGROUND Tart Montmorency cherries have been reported to contain high levels of phytochemicals including melatonin, a molecule critical in regulating the sleep-wake cycle in humans. PURPOSE The aim of our investigation was to ascertain whether ingestion of a tart cherry juice concentrate would increase the urinary melatonin levels in healthy adults and improve sleep quality. METHODS In a ...

BACKGROUND Delirium is characterized by disturbances in circadian rhythm. Melatonin regulates our circadian rhythm. Our aim was to compare preoperative cerebrospinal fluid (CSF) melatonin levels in patients with and without postoperative delirium. METHODS Prospective cohort study with hip fracture patients ≥ 65 years who were acutely admitted to the hospital for surgical treatment and receive...

Melatonin signals time of day and time of year in mammals by virtue of its pattern of secretion, which defines 'biological night.' It is supremely important for research on the physiology and pathology of the human biological clock. Light suppresses melatonin secretion at night using pathways involved in circadian photoreception. The melatonin rhythm (as evidenced by its profile in plasma, sali...

Melatonin is synthesized and released into the circulation by the pineal gland in a circadian rhythm. Melatonin has been demonstrated to differentially alter blood flow to assorted vascular beds by the activation of different melatonin receptors in animal models. The purpose of the present study was to determine the effect of melatonin on blood flow to various vascular beds in humans. Renal (Do...

Melatonin, an indoleamine molecule, regulates a wide range of physiological functions during the growth, morphogenesis, and response plants to abiotic stresses. We examined effect exogenous melatonin application (5, 10, 20 mg·L-1) on growth antioxidant enzyme activity Kimchi cabbage under high temperature (air 32/26°C) drought stress (soil moisture 20–24%) conditions. Application 10 mg·L-1 alle...

Salt and alkaline stress is one of the important problems restricting agricultural production afforestation projects. This kind will greatly limit growth development forest trees. Recently, melatonin has been gradually realized as a strong antioxidant due to its regulatory protective roles in process plant development. study takes Xin Lin 1 (Populus cathayana × canadansis ‘Xin 1’) research obje...
