Overview of the Neuroprotective Effects of the MAO-Inhibiting Antidepressant Phenelzine.

Cell Mol Neurobiol 2021 Apr 10. Epub 2021 Apr 10.

Department of Psychiatry (Neurochemical Research Unit), University of Alberta, 12-105B Clinical Sciences Building, Edmonton, AB, T6G 2G3, Canada.

Phenelzine (PLZ) is a monoamine oxidase (MAO)-inhibiting antidepressant with anxiolytic properties. This multifaceted drug has a number of pharmacological and neurochemical effects in addition to inhibition of MAO, and findings on these effects have contributed to a body of evidence indicating that PLZ also has neuroprotective/neurorescue properties. These attributes are reviewed in this paper and include catabolism to the active metabolite β-phenylethylidenehydrazine (PEH) and effects of PLZ and PEH on the GABA-glutamate balance in brain, sequestration of reactive aldehydes, and inhibition of primary amine oxidase.

Disruption of model-based decision making by silencing of serotonin neurons in the dorsal raphe nucleus.

Curr Biol 2021 Mar 31. Epub 2021 Mar 31.

Department of Neuropharmacology, Faculty of Medicine and Graduate School of Medicine, Hokkaido University, N15 W7 Kita-ku, Sapporo 060-8638, Japan.

Adapting to changing environmental conditions requires a prospective inference of future actions and their consequences, a strategy also known as model-based decision making. In stable environments, extensive experience of actions and their consequences leads to a shift from a model-based to a model-free strategy, whereby behavioral selection is primarily governed by retrospective experiences of positive and negative outcomes. Human and animal studies, where subjects are required to speculate about implicit information and adjust behavioral responses over multiple sessions, point to a role for the central serotonergic system in model-based decision making.

Evaluating cannabidiol (CBD) expectancy effects on acute stress and anxiety in healthy adults: a randomized crossover study.

Psychopharmacology (Berl) 2021 Apr 4. Epub 2021 Apr 4.

Department of Psychology and Neuroscience, Dalhousie University, Life Sciences Centre, 1355 Oxford Street, PO Box 15000, Halifax, Nova Scotia, B3H 4R2, Canada.

Rationale: Cannabidiol (CBD) has been reported to attenuate stress and anxiety, but little is known about the extent to which such effects result from pharmacological versus expectancy factors.

Objectives: We evaluated whether CBD expectancy alone could influence stress, anxiety, and mood, and the extent to which beliefs regarding CBD effects predicted these responses.

Methods: In this randomized crossover study, 43 health adults (23 women) attended two experimental laboratory sessions, where they self-administered CBD-free hempseed oil sublingually. Read More

Brain Sci 2021 Mar 30;11(4). Epub 2021 Mar 30.

Institute of Experimental Medicine, 1085 Budapest, Hungary.

In adults, vasopressin exerts an anxiogenic effect, but less is known about the perinatal period. As a sign of distress, rat pups emit ultrasonic vocalizations when they are separated from their mothers, known as maternal separation-induced ultrasonic vocalization (MS-USV). Previously, reduced MS-USV was reported in 7-8-day-old genetically vasopressin-deficient Brattleboro rats. Read More

Testosterone works through androgen receptors to modulate neuronal response to anxiogenic stimuli.

Neurosci Lett 2021 Mar 27;753:135852. Epub 2021 Mar 27.

Psychology Department, 293 Farm Lane, Giltner Room 108, East Lansing, MI 48824, United States; Neuroscience Program, 293 Farm Lane, Giltner Room 108, East Lansing, MI 48824, United States.

Testosterone (T) exerts anxiolytic effects through functional androgen receptors (ARs) in rodents. T treatment of castrated mice reduces anxiety-like behavior in wild-type (WT) males, but not males with a spontaneous mutation that renders AR dysfunctional (testicular feminization mutation, Tfm). Using Cre-LoxP technology we created males carrying induced dysfunctional AR allele (induced TFM; iTfm) to determine the brain regions responsible for T-induced anxiolysis. Read More

J Gerontol A Biol Sci Med Sci 2021 Mar 29. Epub 2021 Mar 29.

The Irish Longitudinal Study on Ageing, Trinity College Dublin, Ireland.

Individuals with anxiety disorders exhibit lower intrinsic functional connectivity between prefrontal cortical areas and subcortical regions. The prefrontal cortex (PFC) is sensitive to the acute and chronic effects of physical activity (PA), while the anxiolytic effects of PA are well known. The current study examined the association of generalised anxiety disorder (GAD), and its interaction with PA, with resting-state left PFC oxygenation. Read More

Prospects for the Use of Cannabinoids in Psychiatric Disorders.

Front Psychiatry 2021 12;12:620073. Epub 2021 Mar 12.

Laboratory of Palliative Medicine, Department of Social Medicine and Public Health, Medical University of Warsaw, Warsaw, Poland.

Increasing evidence suggests an essential role of the endocannabinoid system in modulating cognitive abilities, mood, stress, and sleep. The psychoactive effects of cannabis are described as euphoric, calming, anxiolytic, and sleep-inducing and positively affect the mood, but can also adversely affect therapy. The responses to cannabinoid medications depend on the patient's endocannabinoid system activity, the proportion of phytocannabinoids, the terpenoid composition, and the dose used. Read More

A selanylimidazopyridine (3-SePh-IP) reverses the prodepressant- and anxiogenic-like effects of a high-fat/high-fructose diet in mice.

J Pharm Pharmacol 2021 Mar;73(5):673-681

Departamento de Ciências Fisiológicas, Universidade Federal de Santa Catarina, Florianópolis, SC, Brazil.

Objective: While chronic feeding with high-fat or high-sugar diets is known related to obesity and type 2 diabetes, later data have indicated that it is also related to depression and anxiety appearance. In this regard, multi-target drugs raise considerable interest as promising therapeutic solutions to complex diseases. Considering the pharmacological effects of the imidazopyridine-derivative moiety imidazo[1,2-a]pyridine and the organoselenium molecules, the combination of both could be a feasible strategy to develop efficient drugs to handle obesity and related comorbidities, for example dyslipidemia and mood disorders.

Transcutaneous Auricular Neurostimulation (tAN): A Novel Adjuvant Treatment in Neonatal Opioid Withdrawal Syndrome.

Front Hum Neurosci 2021 8;15:648556. Epub 2021 Mar 8.

Department of Psychiatry & Behavioral Sciences, Brain Stimulation Division, Medical University of South Carolina, Charleston, SC, United States.

Maternal opioid use during pregnancy is a growing national problem and can lead to newborns developing neonatal opioid withdrawal syndrome (NOWS) soon after birth. Recent data demonstrates that nearly every 15 min a baby is born in the United States suffering from NOWS. The primary treatment for NOWS is opioid replacement therapy, commonly oral morphine, which has neurotoxic effects on the developing brain. Read More

Synthesis and characterization of molecularly imprinted polymers for the selective extraction of oxazepam from complex environmental and biological samples.

Anal Bioanal Chem 2021 Mar 22. Epub 2021 Mar 22.

Laboratory of Analytical, Bioanalytical Sciences and Miniaturization, Chemistry, Biology and Innovation (CBI) UMR 8231, ESPCI Paris PSL, CNRS, PSL University, 75005, Paris, France.

Oxazepam, one of the most frequently prescribed anxiolytic drugs, is not completely removed from wastewater with conventional treatment processes. It can thus be found at trace levels in environmental water, with human urine constituting the major source of contamination. This study focused on the development and characterization of molecularly imprinted polymers (MIPs) for the selective solid-phase extraction of oxazepam at trace levels from environmental water and human urine samples.

The therapeutic potential of GLP-1 analogues for stress-related eating and role of GLP-1 in stress, emotion and mood: a review.

Prog Neuropsychopharmacol Biol Psychiatry 2021 Mar 16;110:110303. Epub 2021 Mar 16.

Department of Medicine (St Vincent's), University of Melbourne, Victoria, Australia; Dept. of Endocrinology, Austin Health, Victoria, Australia. Electronic address:

Stress and low mood are powerful triggers for compulsive overeating, a maladaptive form of eating leading to negative physical and mental health consequences. Stress-vulnerable individuals, such as people with obesity, are particularly prone to overconsumption of high energy foods and may use it as a coping mechanism for general life stressors. Recent advances in the treatment of obesity and related co-morbidities have focused on the therapeutic potential of anorexigenic gut hormones, such as glucagon-like peptide 1 (GLP-1), which acts both peripherally and centrally to reduce energy intake.
