Abstract
Light in the external environment might affect cardiovascular function. The light disruption seems to be related to changes in cardiovascular physiological functions, and disturbing light may be a risk factor for cardiovascular diseases. Prior studies have found that light disruption after myocardial infarction (MI) exacerbates cardiac remodeling, and the brain-heart sympathetic nervous system may be one of the key mechanisms. However, how to improve light-disrupted cardiac remodeling remains unclear. Melatonin is an indoleamine secreted by the pineal gland and controlled by endogenous circadian oscillators within the suprachiasmatic nucleus, which is closely associated with light/dark cycle. This study aimed to explore whether melatonin could improve light-disrupted cardiac remodeling and modulate the brain-heart sympathetic nervous system. Our study revealed that light disruption reduced serum melatonin levels, aggravated cardiac sympathetic remodeling, caused overactivation of the brain-heart sympathetic nervous system, exacerbated cardiac dysfunction, and increased cardiac fibrosis after MI, while melatonin treatment improved light disruption-exacerbated cardiac remodeling and brain-heart sympathetic hyperactivation after MI. Furthermore, RNA-Seq results revealed the significant changes at the cardiac transcription level. In conclusion, melatonin may be a potential therapy for light-disrupted cardiac remodeling.

Abstract
INTRODUCTION Melatonin synchronizes circadian rhythms with light/dark period and it was demonstrated to correct chronodisruption. Several melatonin receptor agonists with improved pharmacokinetics or increased receptor affinity are being developed, three of them are already in clinical use. However, the actions of melatonin extend beyond chronobiology to cardiovascular and metabolic systems as well. Given the high prevalence of cardiovascular disease and their common occurrence with chronodisruption, it is of utmost importance to classify the cardiometabolic effects of the newly approved and putative melatoninergic drugs. AREAS COVERED In the present review, the available (although very sparse) data on such effects, in particular by the approved (circadin, ramelteon, agomelatine) or clinically advanced (tasimelteon, piromelatine = Neu-P11, TIK-301) compounds are summarized. The authors have searched for an association with blood pressure, vascular reactivity, ischemia, myocardial and vascular remodeling and metabolic syndrome. EXPERT OPINION The data suggest that cardiovascular effects of melatonin are at least partly mediated via MT(1)/MT(2) receptors and associated with its chronobiotic action. Therefore, despite the sparse direct evidence, it is believed that these effects will be shared by melatonin analogs as well. With the expected approval of novel melatoninergic compounds, it is suggested that the investigation of their cardiovascular effects should no longer be neglected.

Abstract
AIM To evaluate the effect of phototherapy on gastrointestinal smooth muscle activity and oxidative stress. METHODS Wistar albino rats (n = 18, in the first 7 days of life) weighing 7 ± 2 g with both sexes were included in the study. The animals were randomized into three groups. In control group (CG), median laparotomy was performed to obtain 1 cm of jejunum, terminal ileum and colonic segments. In the phototherapy group (PTG), led phototherapy with a wave density of 40 μw/cm(2)/nm were used (Bilitron 3006, Fanem, Brasil). The efficacy surface of phototherapy was 30-40 cm and the exposure distance was 30 cm. The duration of phototherapy was 24 h. Sham group (SG) received white light with the same wave density and exposure distance. The oxidative stress markers and contraction responses were investigated from intestinal segments obtained from experiments. RESULTS The jejunum segments showed significantly lowered contraction response to carbachol in SG when compared to CG and PTG (p < 0.05). Decreased contractile response to KCl was detected in both SG and PTG in terminal ileum segments. MDA levels showed no difference between groups (p > 0.05). Total sulfhydryl (T-SH) levels were found significantly increased in PTG when compared to CG and SG (p < 0.05). When NO levels were evaluated, NO levels were found decreased in PTG and SG with respect to CG (p < 0.05). CONCLUSION PT may cause various alterations in oxidant/antioxidant system in intestinal segments. Unlike to clinical findings, decreased contractile responses were detected in rat gastrointestinal smooth muscles after PT.
