The effect of melatonin on endothelial dysfunction in patients after acute coronary syndrome: The MEFACS randomized clinical trial.

Endothelial dysfunction (ED) precedes acute coronary syndrome. Oxidative stress results in ED but is reversible. Melatonin is aside from being a circadian hormone, also an antioxidant.

Liraglutide Decreases Hepatic Inflammation and Injury in Advanced Lean Non-Alcoholic Steatohepatitis.

Although commonly associated with obesity, non-alcoholic fatty liver disease (NAFLD) is also present in the lean population representing a unique disease phenotype. Affecting 25% of the world's population, NAFLD is associated with increased mortality especially when progressed to non-alcoholic steatohepatitis (NASH). However, no approved pharmacological treatments exist.

Long term Westernized diet leads to region-specific changes in brain signaling mechanisms.

Western diets, high in fat and energy, are associated with cognitive deficits in humans and animal models, but the underlying mechanisms are not fully elucidated. This includes whether diet-induced dyslipidemia per se negatively impacts brain signaling. Here we investigate the effects of dyslipidemia induced by two high fat diets with or without high sucrose on hippocampal and frontal cortical oxidative stress, brain-derived neurotrophic factor (BDNF) and down-stream markers of synaptic plasticity, as well as alterations in monoaminergic neurotransmitter levels.

Effect of High Inspiratory Oxygen Fraction on Endothelial Function in Healthy Volunteers: A Randomized Controlled Crossover Pilot Study.

It has been suggested that high inspiratory oxygen concentrations during anesthesia may be associated with higher postoperative mortality due to endothelial dysfunction. A randomized controlled crossover study was conducted with 25 healthy male volunteers. They inhaled an oxygen concentration of 30% and 80%.
