Several pathologies, such as pain and inflammation, are modulated by different pathways, making it necessary to develop drugs capable of modulating different pathways. Based on that, we investigated the antinociceptive and anti-inflammatory effect of 3-(4-chlorophenylselanyl)-1-methyl-1H-indole (CMI), as well as the systems involved in these actions. This study evaluated the antinociceptive and anti-inflammatory effects of CMI [0.0001-10mg/kg administered intragastrically (i.g.)] in the formalin, glutamate, hot plate, ear edema induced by croton oil and paw edema induced by formalin tests...

The idea that gut-derived satiation signals influence food reward has recently gained traction, but this hypothesis is largely based on studies focused on neural circuitry, not the peripherally released signals. Here, we directly tested the hypothesis that intragastric (IG) nutrient infusion can suppress motivation for food. In a series of experiments, IG sucrose infusion (15 kcal) significantly and reliably reduced operant responding for a sucrose reward on a progressive ratio (PR) schedule. Moreover, food deprivation for 24 h before the test session did not prevent the suppressive effect of nutrients...

Anxiety disorders are one of the most common mental health problems worldwide, but the exact pathophysiology remains largely unknown. It has been demonstrated previously that administration of exogenous ketone supplement KSMCT (ketone salt/KS + medium chain triglyceride/MCT oil) by intragastric gavage for 7 days decreased the anxiety level in genetically absence epileptic Wistar Albino Glaxo/Rijswijk (WAG/Rij) rats. To investigate the potential role of the adenosinergic system in the pathomechanism of anxiety we tested whether the inhibition of adenosine A1 receptors (A1 Rs) influence the anxiolytic effect of the exogenous ketone supplement...

A 25-year-old obese woman experienced ischemic renal injury as a complication of intragastric balloon (IGB) insertion for weight reduction. Although IGB is associated with a low risk of renal injury in the form of acute renal failure, this presentation has never been reported. The patient responded well to treatment, with complete clinical and radiologic resolution after balloon removal. She did not have an apparent cause of renal ischemia other than a significant compression of the renal vessels by the balloon as seen on imaging...
