There is a growing body of evidence from randomized controlled trials which indicates that consumption of berries has a positive effect upon the cognitive function of healthy adults. It has been recommended that studies combining cognitive and physiological measures be undertaken in order to strengthen the evidence base for the putative effects of flavonoid consumption on cognitive outcomes. This pilot study utilized a randomized, double-blind and placebo controlled crossover design to assess the influence of the acute administration of anthocyanin-rich blackcurrant juice, standardized at 500 mg of polyphenols, on mood and attention...

Nociceptin /Orphanin FQ Peptide" receptor (NOPr) is a G-protein-coupled receptor with the nociceptin/orphanin FQ peptide (N/OFQ) as endogenous agonist. It is expressed in the nervous system as well as in some non-neural tissues. Its activation has pronociceptive effect at the supraspinal level, whereas at the spinal level it produces nociceptive effects at low doses and antinociceptive effects at higher doses. NOPr is also involved in mood and blood pressure regulation, immunoregulation, airway constriction, feeding, urination, bowel motility, learning and memory...

Context • Pathological anxiety, which affects approximately one-third of the world population, is an inadequate, irrational reaction of an organism to the environment and to a potential threat. Despite advancements in pharmacotherapy for anxiety disorders, further studies are still necessary to search for new substances possessing the desired anxiolytic effects, with as few unwanted effects as possible. Objective • This study intended to examine the characteristics of medicinal plant materials that exhibit anxiolytic properties, with a special emphasis on the mechanisms of action of their active ingredients on the systems involved in the pathophysiology of anxiety...

The consumption of a high-fat diet (HFD) and obesity have been associated not only with metabolic diseases but also with neuropsychiatric diseases, such as depression and anxiety. However, results on the effects of an HFD on anxiety are controversial, since both anxiogenic and anxiolytic effects have been reported. In this study, we evaluated the effects of both short- and long-term intake of an HFD on anxiety-like behaviors. To explore the impact of time on the association between an HFD and anxiety, mice were fed with an HFD for 4 weeks or 12 weeks...

Emerging evidence indicates that loss of inhibitory tone in amygdala with its subsequent overactivation contributes to the development of multiple mental disorders such as anxiety disorders and post-traumatic stress disorder (PTSD). Harmine is a member of natural β-carboline alkaloids which can readily cross the blood brain barrier and displays significant antidepressant and anxiolytic effects in rodents. However, the underlying neurobiological mechanisms are largely unknown. Here, by using whole-cell patch clamp recordings in in vitro amygdala slices, we examined the effect of harmine on glutamatergic and GABAergic transmission onto basal amygdala (BA) projection neurons (PNs)...

OBJECTIVE Awake craniotomies have become a feasible tool over time to treat brain tumors located in eloquent regions. Different techniques have been applied in neurooncology centers. Both "asleep-awake-asleep" (asleep) and "conscious sedation" were used subsequently at the authors' neurosurgical department. Since 2013, the authors have only performed conscious sedation surgeries, predominantly using the α2-receptor agonist dexmedetomidine as the anesthetic drug. The aim of this study was to compare both mentioned techniques and evaluate the clinical use of dexmedetomidine in the setting of awake craniotomies for glioma surgery...

Binge alcohol-drinking elicits symptoms of negative affect such as anxiety upon cessation, which is a source of negative reinforcement for perpetuating this pattern of alcohol abuse. Binge-induced anxiety during early (24 h) withdrawal is associated with increased expression of metabotropic glutamate receptor 5 (mGlu5) within the nucleus accumbens shell (AcbSh) of adult male mice, but was unchanged in anxiety-resilient adolescents. Herein, we determined the role of mGlu5 signaling in withdrawal-induced anxiety via pharmacological manipulation using the mGlu5 negative allosteric modulator MTEP and the positive allosteric modulator CDPPB...

Anxiolytic activity has been associated with GABAA α2 and α3 subunits. Several target compounds were identified and required in C-14 labeled form to enable a better understanding of their DMPK properties. AZD7325 is a selective GABAA α2 and α3 receptor modulator intended for the treatment of anxiety through oral administration. A great number of AZD7325 metabolites were observed across species in vivo, whose identification was aided by [14 C]AZD7325. An interesting metabolic cyclization and aromatization pathway leading to the tricyclic core of M9 and the oxidative pathways to M10 and M42 are presented...

Agmatine is a polyamine endogenously synthesized from arginine and is considered to be a new neurotransmitter. Agmatine has been implicated in the pathophysiology of several diseases such as anxiety disorder, depression, and schizophrenia. Agmatine also possesses anticonvulsant, neuroprotective, antiapoptotic, antioxidant, anxiolytic, and antidepressant effects. Furthermore, agmatine inhibits the nitric oxide synthase enzyme and exerts antagonist effects on NMDA, alpha-2, and imidazoline receptors. Considering these characteristics, the present study investigated whether agmatine plays a role in the pathogenesis of autistic spectrum disorders (ASDs)...

The spice saffron is made from the dried stigmas of the plant Crocus sativus L. The main use of saffron is in cooking, due to its ability to impart colour, flavour and aroma to foods and beverages. However, from time immemorial it has also been considered a medicinal plant because it possesses therapeutic properties, as illustrated in paintings found on the island of Santorini, dated 1627 BC. It is included in Catalogues of Medicinal Plants and in the European Pharmacopoeias, being part of a great number of compounded formulas from the 16th to the 20th centuries...

Although the current treatment for anxiety is effective, it promotes a number of adverse reactions and medical interactions. Inhaled essential oils have a prominent action on the central nervous system, with minimal systemic effects, primarily because of reduced systemic bioavailability. The effects of drugs on the consolidation of fear conditioning reflects its clinical efficacy in preventing a vicious cycle of anticipatory anxiety leading to fearful cognition and anxiety symptoms. In this study, we investigated the effects of inhaled Lavandula angustifolia essential oil on the consolidation of aversive memories and its influence on c-Fos expression...
