Neuropathic pain impacts approximately 3-4.5% of the global population and remains an unresolved health problem. The management of neuropathic pain has two distinct goals-prevention of development and control of established neuropathic pain. We examined the impact of both prophylactic and therapeutic treatments with the tricyclic antidepressant desipramine on the development and maintenance of toxic neuropathic pain induced by the chemotherapeutic agent paclitaxel. We also investigated the involvement of endogenous analgesic (i...

7,8-Dihydroxyflavone (7,8-DHF) is a naturally-occurring flavone which possesses good bioavailability. Due to its ability to cross the blood-brain barrier, previous studies have demonstrated that 7,8-DHF was a potent tropomyosin-related kinase B (TrkB) agonist, and produced antidepressant-like effects in mouse forced swimming test and tail suspension test. However, it has not been evaluated in chronic mild stress (CMS), a classical depression model modulating the processes of major depression in human. In the present study, we not only evaluated the depressive-like behaviors, but also measured the key proteins of TrkB signaling in mice exposed to CMS...

BACKGROUND: Hyponatremia may occur after initiation of a second-generation antidepressant drug. However, the magnitude of this risk among older adults in routine care is not well characterized. STUDY DESIGN: Retrospective, population-based, matched-cohort study. SETTING & PARTICIPANTS: In Ontario, Canada, 2003 to 2012, we compared older adults with a mood or anxiety disorder who were dispensed 1 of 9 second-generation antidepressant drugs with matched adults with comparable indicators of baseline health who were not dispensed an antidepressant drug (n=138,246 per group)...

OBJECTIVE: Major depressive disorder is characterized by reduced reward-related striatal activation and dysfunctional reward learning, putatively reflecting decreased dopaminergic signaling. The goal of this study was to test whether a pharmacological challenge designed to facilitate dopaminergic transmission can enhance striatal responses to reward and improve reward learning in depressed individuals. METHOD: In a double-blind placebo-controlled design, 46 unmedicated depressed participants and 43 healthy control participants were randomly assigned to receive either placebo or a single low dose (50 mg) of the D2/D3 receptor antagonist amisulpride, which is believed to increase dopamine signaling through presynaptic autoreceptor blockade...

BACKGROUND/AIMS: To investigate the potential inhibitory effects of 18 clinically available antidepressants on acetylcholine (ACh)-induced contractions in guinea pig urinary bladder smooth muscle (UBSM) in order to predict whether they may induce voiding impairment. METHODS: Concentration-response curves for ACh-induced contractions in guinea pig UBSM strips were obtained in the absence or presence of selected antidepressants. When inhibitory effects indicated competitive antagonism, pA2 values against ACh were calculated and compared to plausible antidepressant blood concentrations...

CB1 and TRPV1 receptors may have opposite roles in modulating neural activity and, consequently, in regulating the stress response. These receptors are widely expressed in several brain structures, including the ventral medial pre-frontal cortex (vmPFC). The functional consequences of the interaction between CB1 and TRPV1, however, have scarcely been explored. Therefore, we investigated if CB1 and TRPV1 receptors located in the vmPFC would be involved in the behavioral changes induced by the stress of the forced swim test (FST)...

BACKGROUND AND PURPOSE: Since GABAergic dysfunction underlies a variety of neurological and psychiatric disorders, numerous strategies leading to the augmentation of GABAergic neurotransmission have been introduced. One of them is the inhibition of GABA reuptake from the synaptic cleft mediated by four plasma membrane GABA transporters (GAT1-4). GAT1 which is exclusively expressed in the brain is an interesting target for centrally acting drugs. In this research, pharmacological properties of a novel, highly potent and selective inhibitor of GAT1, the guvacine derivative named DDPM-2571, were assessed in vivo...

BACKGROUND: Low back pain is a major clinical and public health problem, with limited evidence-based treatments. Low-dose antidepressants are commonly used to treat pain in chronic low back pain. However, their efficacy is unproven. The aim of this pragmatic, double-blind, randomised, placebo-controlled trial is to determine whether low-dose amitriptyline (an antidepressant) is more effective than placebo in reducing pain in individuals with chronic low back pain. METHODS/DESIGN: One hundred and fifty individuals with chronic low back pain will be recruited through hospital and private medical and allied health clinics, advertising in local media and posting of flyers in community locations...

Extracts from the husk fiber of Cocos nucifera are used in folk medicine, but their actions on the central nervous system have not been studied. Here, the anxiolytic and antidepressant effects of the standardized hydroalcoholic extract of C. nucifera husk fiber (HECN) were evaluated. Male Swiss mice were treated with HECN (50, 100, or 200 mg/kg) 60 min before experiments involving the plus maze test, hole-board test, tail suspension test, and forced swimming test (FST). HECN was administered orally (p.o.) in acute and repeated-dose treatments...

An accumulating body of evidence has demonstrated that inflammation is associated with the pathology of depression. We recently found that psychological stress induces inflammation in the hippocampus of the rat brain through the inflammasome, a component of the innate immune system. Microglia, the resident macrophages in the brain, play a central role in the innate immune system and express inflammasomes; thus, we hypothesized that hippocampal microglia would be key mediators in the development of depression via stress-induced inflammation...

We studied the interaction between mGlu7 and α1-adrenergic receptors in heterologous expression systems, brain slices, and living animals. L-2-Amino-4-phosphonobutanoate (L-AP4), and l-serine-O-phosphate (L-SOP), which activate group III mGlu receptors, restrained the stimulation of polyphosphoinositide (PI) hydrolysis induced by the α1-adrenergic receptor agonist, phenylephrine, in HEK 293 cells co-expressing α1-adrenergic and mGlu7 receptors. The inibitory action of L-AP4 was abrogated by (i) the mGlu7 receptor antagonist, XAP044; (ii) the C-terminal portion of type-2 G protein coupled receptor kinase; and (iii) the MAP kinase inhibitors, UO126 and PD98059...

Depression and pain comorbidity represent a neuropsychiatric condition with substantial socioeconomic impact to society. The commonly used antidepressants and analgesics to treat this comorbidity have shown restricted clinical efficacy. In this way, the aim of this study was to investigate the behavioral, biochemical and neurochemical effects of a p,p'-methoxyl-diphenyl diselenide (OMePhSe)2 supplemented diet on pain-depression dyad induced by reserpine in rats. Adult Wistar rats were fed with 10mg (MeOPhSe)2 per kg of rat chow supplemented diet for 30 days...

INTRODUCTION: Considering that estradiol (E2) and n-3 polyunsaturated fatty acids (PUFAs) have roles in neurogenesis and in neurotransmission, we examined whether the association of PUFAs with incident depressive symptoms in postmenopausal women is modified by hormone therapy (HT) use or estrogen status. METHODS: Women (N=1616) free of depressive symptoms at baseline (2000-2002) in the Multi-Ethnic Study of Atherosclerosis were classified by HT usage and quartiles of dietary eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA), and the sum EPA+DHA...

Electroconvulsive therapy (ECT) is considered an effective treatment for major depression with melancholic features. However, neurocognitive side-effects such as anterograde amnesia still regularly occur. The present study aims to evaluate the severity and course of anterograde amnesia in severely depressed patients undergoing ECT. In a prospective naturalistic study, anterograde memory function was assessed among inpatients who underwent ECT (n = 11). Subjects met DSM-IV criteria for major depressive disorder...

Repetitive transcranial magnetic stimulation (rTMS) is an emerging non-pharmacological approach to treating many brain-based disorders. rTMS uses electromagnetic coils to stimulate areas of the brain non-invasively. Deep transcranial magnetic stimulation (dTMS) with the Brainsway H1-coil system specifically is a type of rTMS indicated for treating patients with major depressive disorder (MDD) who are resistant to medication. The unique H1-coil design of this device is able to stimulate neuronal pathways that lie deeper in the targeted brain areas than those reached by conventional rTMS coils...
