NLX-101, a 5-HT receptor-biased agonist, improves pattern separation and stimulates neuroplasticity in aged rats.

5-HT serotonin receptors may play a role in cognitive function changes related to advanced age. Here, we investigated the effects of acute and repeated treatment with NLX-101 (F15599), a postsynaptic 5-HT receptor-biased agonist, and F13714, a presynaptic 5-HT receptor-biased agonist on spatial object pattern separation (OPS) in aged (22-24 months) rats. Neuroplasticity markers including brain-derived neurotrophic factor, PSD95, synaptophysin, and doublecortin were evaluated in the hippocampus.

Activation of 5-HT postsynaptic receptors by NLX-101 results in functional recovery and an increase in neuroplasticity in mice with brain ischemia.

Pharmacological interventions that selectively activate serotonin 5-hydroxytryptramine-1A (5-HT) heteroreceptors may prevent or attenuate the consequences of brain ischemic episodes. The present study investigated whether the preferential 5-HT postsynaptic receptor agonist NLX-101 (a.k.

Protective Effect of Cymbopogon citratus Essential Oil in Experimental Model of Acetaminophen-Induced Liver Injury.

To investigate the hepatoprotective effect of Cymbopogon citratus or lemongrass essential oil (LGO), it was used in an animal model of acute liver injury induced by acetaminophen (APAP). Swiss mice were pretreated with LGO (125, 250 and 500[Formula: see text]mg/kg) and SLM (standard drug, 200[Formula: see text]mg/kg) for a duration of seven days, followed by the induction of hepatotoxicity of APAP (single dose, 250[Formula: see text]mg/kg). The liver function markers alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP) and gamma-glutamyl transferase were determined to evaluate the hepatoprotective effects of the LGO.

Effect of patchouli (Pogostemon cablin) essential oil on in vitro and in vivo leukocytes behavior in acute inflammatory response.

Purpose: The aim of this study was to evaluate the effect of Pogostemon cablin essential oil (PEO) on leukocyte behavior in the inflammatory response.

Methods And Results: PEO was analyzed using Gas Chromatography/Mass Spectrometry (GC/SM) and Nuclear Magnetic Resonance Spectroscopy (NMR) methods and showed predominance of patchoulol (38.50%), α-bulnesene (20.

Anti-inflammatory and antioxidant properties of a novel resveratrol-salicylate hybrid analog.

Resveratrol is a natural compound with a plethora of activities as well as limitations. We recently reported a series of resveratrol-salicylate analogs with potential chemopreventive activity. Herein, we report the anti-inflammatory and antioxidant properties of these resveratrol derivatives.

Hepatoprotective Effect of Pretreatment with Thymus vulgaris Essential Oil in Experimental Model of Acetaminophen-Induced Injury.

Acute liver damage caused by acetaminophen overdose is a significant clinical problem and could benefit from new therapeutic strategies. Objective. This study investigated the hepatoprotective effect of Thymus vulgaris essential oil (TEO), which is used popularly for various beneficial effects, such as its antiseptic, carminative, and antimicrobial effects.
