Published: July 1988

A quantitative gas chromatographic assay for the determination of phenelzine in plasma or other fluids is presented. A stable derivative is formed by cyclization with acetylacetone, and the derivative is separated, purified, and concentrated by liquid-liquid solvent extraction. Analysis of the extracts is by capillary gas chromatography with nitrogen specific detection. Detection limits of less than 1 ng/mL and CVs of 5% at the 10-ng/mL level are attainable with a 2-mL sample and benzylhydrazine as the internal standard.

Background: Monoamine oxidase inhibitors (MAOIs) are considered third-line treatments for treatment resistant depression; however, they are underused in clinical practice.

Aims: This study aimed to assess the efficacy, tolerability, and acceptability of MAOIs for the treatment of depression in comparison with other antidepressant treatments.

Methods: A systematic review and network meta-analysis of randomised clinical trials was performed to compare the efficacy, tolerability and acceptability between MAOIs and other antidepressant treatments for the treatment of depressive episodes.

Objective: The main purpose was to evaluate the efficacy and tolerability of different medications used to treat bulimia nervosa (BN).

Methods: Randomized controlled trials (RCTs) were identified from published sources through searches in PubMed, Cochrane Library, Web of Science, and Embase from inception to November 2022. Primary outcomes were changes in the frequency of binge eating episodes and vomiting episodes from baseline to endpoint.

Although the neurotoxicity of the common chemical bisphenol A (BPA) to the mouse hippocampus has been often reported, the mechanism underlying BPA-induced depression-like behavior in mice remains unclear. We evaluated BPA's role in inducing depressive-like behavior by exposing male mice to different BPA concentrations (0, 0.01, 0.
