Effects of Asenapine and Paliperidone on Depression, Anxiety and Analgesy in Mice: Alterations in Brain Neurotrophic Factors, Neurogenesis, and Blood Enzyme Levels.

Schizophrenia, an important brain neurodevelopmental disorder, is observed in 1% of the global population. New-generation antipsychotics have been developed as alternatives to typical antipsychotics for more effective and safe therapy. Chronic administration of asenapine and paliperidone compared to haloperidol on depression, anxiety and analgesy in the forced swimming test (FST), elevated plus maze (EPM) and hot plate tests were examined in mice.

Exenatide upregulates gene expression of glucagon-like peptide-1 receptor and nerve growth factor in streptozotocin/nicotinamide-induced diabetic mice.

Glucagon-like peptide-1 (GLP-1) is an incretin hormone that has modulating effects on insulin release. GLP-1 and receptors for GLP-1 are widely expressed throughout the body including the brain. The expression of GLP-1 receptors is very specific to large neurons in hippocampus, neocortex, and cerebellum.

Effects of long-term treatment with haloperidol, clozapine and aripiprazole on mice isolated vas deferens.

Purpose: Sexual dysfunction is a common condition in patients taking antipsychotics and is the most bothersome symptom and adverse drug effect, resulting in a negative effect on treatment compliance. Pharmacology research into human ejeculatory disorders is limited to clinical studies with registered drugs affecting the ejaculation process; therefore, animal research has become the need. We aimed to investigate the effects of haloperidol, clozapine and aripiprazole on serotonin, noradrenaline, adenosine triphosphate (ATP) and potassium chloride (KCl)-induced contractions of the vas deferens in order to evaluate the effect of haloperidol, clozapine and aripiprazole on the contraction of the vas deferens.

Superior effects of quetiapine compared with aripiprazole and iloperidone on MK-801-induced olfactory memory impairment in female mice.

Cognitive dysfunction is commonly observed in schizophrenic patients and the administration of antipsychotic treatments results in different outcomes. Although the typical antipsychotic treatments, such as haloperidol, appear to be unable to improve cognition dysfunction, the atypical antipsychotic drugs (quetiapine, aripiprazole and iloperidone) exert a beneficial effect. The purpose of the current study was to investigate the effects of atypical antipsychotics on olfactory memory in mice, utilizing the social transmission of food preference (STFP) tests to evaluate the effects of drugs on MK-801-induced cognitive dysfunction.

Effects of Acute Administration of Adipokinetic Hormone on Depression, Anxiety, Pain, Locomotion and Memory in Mice.

The neurosecretory cells in the corpus cardiacum of insects synthesize a set of hormones that are called adipokinetic, hypertrehalosemic or hyperprolinemic depending on the insect in question. They are the Adipokinetic Hormone/Red Pigment-Concentrating Hormone (AKH/RPCH) family of peptides. The present study investigated the effects of acute administration of Locusta Migratoria (Locmi-AKHII) and Anax Imperator (Anaim-AKH) on depression, anxiety, pain (analgesy), locomotion and memory in mice in forced swimming (FST), elevated plus maze (EPM), hot plate, locomotor activity and passive avoidance tests.
