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.

COVID-19 quarantine and depression in patients with congenital heart disease.

Am J Cardiovasc Dis 2021 15;11(1):80-86. Epub 2021 Feb 15.

Research Unit, Complejo Hospitalario Universitario Insular-Materno Infantil Las Palmas de Gran Canaria 35016, Spain.

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.

The Neural Network of Neuropeptide S (NPS): Implications in Food Intake and Gastrointestinal Functions.

Pharmaceuticals (Basel) 2021 Mar 26;14(4). Epub 2021 Mar 26.

School of Pharmacy, University of Camerino, via Madonna delle Carceri, 9, 62032 Camerino, Italy.

The Neuropeptide S (NPS), a 20 amino acids peptide, is recognized as the endogenous ligand of a previously orphan G protein-coupled receptor, now termed NPS receptor (NPSR). The limited distribution of the NPS-expressing neurons in few regions of the brainstem is in contrast with the extensive expression of NPSR in the rodent central nervous system, suggesting the involvement of this receptor in several brain functions. In particular, NPS promotes locomotor activity, behavioral arousal, wakefulness, and unexpectedly, at the same time, it exerts anxiolytic-like properties. Read More

The Effect of Vasopressin Antagonists on Maternal-Separation-Induced Ultrasonic Vocalization and Stress-Hormone Level Increase during the Early Postnatal Period.

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

Essential Oils: Pharmaceutical Applications and Encapsulation Strategies into Lipid-Based Delivery Systems.

Pharmaceutics 2021 Mar 3;13(3). Epub 2021 Mar 3.

Laboratory of Drug Delivery Technology, Department of Drug and Health Sciences, University of Catania, Viale A. Doria 6, 95125 Catania, Italy.

Essential oils are being studied for more than 60 years, but a growing interest has emerged in the recent decades due to a desire for a rediscovery of natural remedies. Essential oils are known for millennia and, already in prehistoric times, they were used for medicinal and ritual purposes due to their therapeutic properties. Using a variety of methods refined over the centuries, essential oils are extracted from plant raw materials: the choice of the extraction method is decisive, since it determines the type, quantity, and stereochemical structure of the essential oil molecules.

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

The association between generalized anxiety disorder and resting-state prefrontal cortex oxygenation is modified by self-reported physical activity: results from The Irish Longitudinal Study on Ageing.

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
