Jeremy I Webster, David N Harper, Susan Schenk
Studies that have attributed the discriminative stimulus effects of ±3,4-methylenedioxymethamphetamine (MDMA) to serotonergic mechanisms typically use a relatively low training dose of 1.5 mg/kg. The role of serotonin in the discriminative stimulus effects of higher doses of MDMA is, however, unknown. Separate groups of rats were trained to discriminate MDMA (1.5 or 3.0 mg/kg) from saline using a two-lever, food-reinforced drug-discrimination procedure. Generalization tests were carried out with a range of serotonin and dopamine ligands...

The use of a new class of hybrid materials, called restricted access molecularly imprinted polymers (RAMIPs) seems to present a good strategy for the sample preparation of complex matrices, since these materials combine good protein elimination capacity with high degree selectivity. Mass spectrometers (MS) have been successfully used for polar drug identification and quantification. In order to combine the advantages of both RAMIPs and mass spectrometry, we proposed a study that joins these properties in a single system, where we could analyse tricyclic antidepressants from human plasma, without offline extraction or chromatographic separation...

PURPOSE: The aim of this study was to evaluate the potential of hair analysis to monitor medication adherence in headache patients undergoing chronic therapy. For this purpose, the following parameters were analyzed: the detection rate of 23 therapeutic drugs in headache patients' hair, the degree of agreement between the self-reported drug and the drug found in hair, and whether the levels found in hair reflected the drug intake reported by the patients. METHODS: The study included 93 patients suffering from primary headaches declaring their daily intake of at least one of the following drugs during the 3 months before the hair sampling: alprazolam, amitriptyline, citalopram, clomipramine, clonazepam, delorazepam, diazepam, duloxetine, fluoxetine, flurazepam, levomepromazine, levosulpiride, lorazepam, lormetazepam, mirtazapine, paroxetine, quetiapine, sertraline, topiramate, trazodone, triazolam, venlafaxine, and zolpidem...

WHAT IS KNOWN AND OBJECTIVE: Polymorphisms in cytochrome P450 2D6 and 2C19 can lead to interindividual differences in drug plasma concentrations, affecting clomipramine efficacy. Pharmacokinetic and pharmacogenetic analyses may improve drug therapy. CASE SUMMARY: We report the case of a depressed woman requiring higher doses than standard of clomipramine. Identification of low plasma drug levels led to extensive pharmacogenetic analyses of all genes and major functional polymorphisms reported to affect clomipramine metabolism...

Serotonin syndrome (SS) is a potentially life-threatening condition associated with increased serotonergic activity in central nervous system and may occur during the use of serotonergic drugs. Although increasing frequency of serotonergic drug use in children, pediatricians, emergency medicine and pediatric intensive care specialists have not enough knowledge and experience about SS that is a potentially life-threatening condition. A 12-year-old girl patient was admitted to our emergency room with the history of involuntary contractions on her extremities and alteration of consciousness...

We have previously observed impairing effects of social defeat stress (CSDS) on inhibitory avoidance (IA) in mice. Given the similarity between changes produced by social stress in animals and symptoms of certain human psychopathologies such as depression and anxiety, the effects of the antidepressant clomipramine on IA impairment produced by CSDS were evaluated in the present study. Male CD1 mice were randomly assigned to the groups: non-stressed+saline, non-stressed+clomipramine, stressed+saline and stressed+clomipramine...

Clomipramine (CLO), a tricyclic antidepressant drug, has been used for the treatment of mice infected with Trypanosoma cruzi. In this work we evaluated the effectiveness of CLO treatment upon T. cruzi-infected mice in the chronic phase of the experimental infection using Quantitative polymerase chain reaction (qPCR) and recombinant ELISA. Sixty Swiss albino mice were inoculated with 50 trypomastigote forms of T. cruzi (Tulahuen strain). CLO treatment consisted of 5mg/kg/day during 60days by intraperitoneal injection, beginning on day 90 post infection (p...

Quinpirole (QNP) sensitization is one of the commonly used animal models of obsessive-compulsive disorder (OCD). We have previously shown that QNP-sensitized animals display a robust cognitive flexibility deficit in an active place avoidance task with reversal in Carousel maze. This is in line with numerous human studies showing deficits in cognitive flexibility in OCD patients. Here we explored the effect of clomipramine, an effective OCD drug that attenuates compulsive checking in QNP, on sensitized rats in acquisition and reversal performances in an active place avoidance task...

Breeding clouded leopards (Neofelis nebulosa) ex situ has been a challenge, primarily due to extreme and often fatal male aggression toward females. This study's aim was to determine the degree to which two possible mechanisms-serotonergic pathways and circulating testosterone levels-affect aggressive behavior. Male clouded leopard behavioral and hormonal data were collected during a series of behavior tests administered before and after treatment with either an anxiety-reducing tricyclic antidepressant (clomipramine) or a GnRH agonist (deslorelin)...

Leucocytozoon parasites infect many species of avian hosts, including domestic chicken, and can inflict heavy economic loss on the poultry industry. Two major species of Leucocytozoon parasites have been reported in China, L. sabrazesi and L. caulleryi, although L. sabrazesi appears to be more widespread than L. caulleryi in southern China. The traditional method for detecting Leucocytozoon infection is microscopic examination of blood smears for the presence of mature gametocytes in circulation, which may miss infections with low parasitemia (gametocytemia) or immature gametocytes...

The interrelation of depression and pain is increasingly coming under scrutiny. Although the lateral habenula (LHb) is widely implicated in the pathogenesis of depression and pain, its role in the interaction of depression and pain remains unknown. Thus, the aim of current study was to investigate the role of LHb in rat depression-pain comorbidity. Single extracellular firing recording and immunofluorescence methods were used to compare firing rates and c-Fos expression of the LHb neurons in normal and model rats...

INTRODUCTION: Many antidepressants are indicated for the treatment of major depression. Two network meta-analyses have provided the most comprehensive assessments to date, accounting for both direct and indirect comparisons; however, these reported conflicting interpretation of results. Here, we present a protocol for a systematic review and network meta-analysis aimed at updating the evidence base and comparing all second-generation as well as selected first-generation antidepressants in terms of efficacy and acceptability in the acute treatment of major depression...
