Central and Metabolic Effects of High Fructose Consumption: Evidence from Animal and Human Studies

Fructose consumption has increased dramatically in the last 40 years, and its role in the pathogenesis of the metabolic syndrome has been implicated by many studies. It is most often encountered in the diet as sucrose (glucose and fructose) or high-fructose corn syrup (55% fructose). At high levels, dietary exposure to fructose triggers a series of metabolic changes originating in the liver, le...

Study of the role of CREB, BDNF, and VGF neuropeptide in long term antidepressant activity of crocin in the rat cerebellum

Antidepressant activity of crocin, saffron main component, has been established before. Based on previous study, it is suggested that elevation in the levels of BDNF (brain-derived neurotrophic factor), CREB (cAMP response element binding) and VGF neuropeptide could be considered as one probable molecular mechanisms involved in antidepressant activity of long term crocin administration in the r...

Cannabinoid CB1 Receptors Mediate the Gastroprotective Effect of Neurotensin

Objective(s) Several lines of evidence indicate that neuropeptides exhibit protective properties against gastroduodenal ulcers. Neurotensin, a gut-brain neuropeptide, is implicated in a number of physiological processes in the central nervous system and peripheral tissues including gastrointestinal tract. In the present study, we aimed to investigate the gastroprotective potential of either p...

Evaluation of changes in testosterone concentration of the rat central nervous system following progesterone administration

Neurosteroids are steroids that are produced in the central nervous system (CNS). While progesterone and dehydroepiandostendione (the precursors of testosterone) are among the identified neurosteroids, it is not clear that testosterone could be considered as a neurosteroid. The testosterone synthesis has been demonstrated in the brain of castrated frog, but not in the rat brain. In the present ...
