Zinc and vitamin C supplementation of the body is important for CNS functioning. Zinc ions are involved in the neurotransmission (signal transmission from acetylcholine, catecholamine, serotonin, prostaglandin receptors) and in ubiquitin-related protein degradation. Zinc deficits are associated with Alzheimer's disease and depression. Zinc supplementation (10-30 mg daily) improves neurologic recovery rate in patients with stroke and brain injury, has a positive impact on memory and reduces hyperactivity in children...

The combined infusion of Banisteriopsis caapi stem and Psychotria viridis leaves, known as ayahuasca, has been used for centuries by indigenous tribes. The infusion is rich in N, N-dimethyltryptamine (DMT) and monoamine oxidase inhibitors, with properties similar to those of serotonin. Despite substantial progress in the development of new drugs to treat anxiety and depression, current treatments have several limitations. Alternative drugs, such as ayahuasca, may shed light on these disorders. Here, we present time-course behavioral changes induced by ayahuasca in zebrafish, as first step toward establishing an ideal concentration for pre-clinical evaluations...

We studied the effects of the multi-modal antidepressant, vortioxetine and the SSRI, paroxetine on pineal melatonin and monoamine synthesis in a sub-chronic tryptophan (TRP) depletion model of depression based on a low TRP diet. Female Sprague-Dawley rats were randomised to groups a) control, b) low TRP diet, c) low TRP diet+paroxetine and d) low TRP diet+vortioxetine. Vortioxetine was administered via the diet (0.76mg/kg of food weight) and paroxetine via drinking water (10mg/kg/day) for 14days. Both drugs resulted in SERT occupancies >90%...

BACKGROUND: Recently, depression has been envisioned as more than an alteration in neurotransmitters centered around receptor signaling pathways. Consequently, the precise mechanisms of selective serotonin reuptake inhibitor (SSRI) antidepressant drugs such as fluoxetine are being revisited. Zinc is a trace element that has been long implicated in the psychopathology and therapy of depression. Zinc has been found to be sequestered and dispensed during stress and inflammation through a family of proteins called metallothioneins (MTs)...

Major Depressive Disorder (MDD) is a serious psychiatric condition. Its treatment remains a challenge nowadays. Vortioxetine is a novel antidepressant with a unique profile, as it acts as a multimodal serotoninergic agent. Its efficacy in MDD has been established in many short- and long-term studies, with 7 positive, 4 negative and 1 failed randomized controlled trials. Moreover, its ability to modulate a wide range of neurotransmitters (serotonin, dopamine, norepinephrine, histamine, glutamate or GABA) confers vortioxetine pro-cognitive effects...

Tryptophan (Trp) is an amino acid and an essential component of the human diet. It plays a crucial role in many metabolic functions. Clinicians can use Trp levels in the course of diagnosing various metabolic disorders and the symptoms associated with those diseases. Furthermore, supplementation with this amino acid is considered in the treatment of depression and sleep disorders, mainly due to the Trp relationship with the synthesis of serotonin (5-HT) and melatonin. It is also used in helping to resolve cognitive disorders, anxiety, or neurodegenerative diseases...

Antidepressants are widely prescribed among women to treat depression and anxiety disorders, but studies of their effects on gynecological cancer risk are sparse. We assessed associations between various antidepressants and risk of epithelial ovarian cancer. By using Danish nationwide registers, we identified all women (cases) aged 30 to 84 years with incident epithelial (serous, endometrioid, clear cell or mucinous) ovarian cancer during 2000-2011 (n= 4,103) and matched each case to 20 population controls (n=58,706) by risk-set matching...

AIMS: There is evidence of association between bruxism and the increasingly common central nervous system stimulants prescribed for attention deficit hyperactivity disorder (ADHD), as well as the selective serotonin reuptake inhibitors (SSRIs) often prescribed for depression or anxiety. However, the evidence is not clear on whether these medications inducing bruxism are directly associated with temporomandibular joint disorder (TMD). The aim of this work is to evaluate whether these medications are associated with TMD symptoms...

In the clinic selective serotonin reuptake inhibitors (SSRIs), like Fluoxetine, remain the primary treatment for major depression. It has been suggested that miR-16 regulates serotonin transporters (SERT) via raphe nuclei and hippocampal responses to antidepressants. However, the underlying mechanism and regulatory pathways are still obtuse. Here, a chronic unpredicted mild stress (CUMS) depression model in rats was established, and then raphe nuclei miR-16 and intragastric Fluoxetine injections were administered for a duration of 3 weeks...

The serotonin syndrome is a serioius medical condition due due to an intensive stimulation of setonin receptors. It is a rare, but severe, consequence of interaction between serotomimetic agents. This is a report of a 70-year-old woman steadily in therapy with venlafaxine and rizatriptan for migraine and major depressive syndrome. She was admitted to neurology unit for decreased light reflex with miotic pupils, global hyperreflexia, tremor, anxiety, ataxia and incoordination. The patient was diagnosed as a probable case of serotonin syndrome due to a pharmacological interaction between venlafaxine and rizatriptan trigged by opioid intake...

Obstetrician-gynecologists (ob-gyns) are well-positioned to detect symptoms of perinatal depression; however, little is known about how ob-gyns respond. The purpose of this study was to evaluate ob-gyns' beliefs and practices related to prenatal depression screening and antidepressant prescription during pregnancy. A larger survey on prenatal medication was developed at the American College of Obstetricians and Gynecologists (ACOG) and distributed to a sample of 1000 Fellows. The overall response rate was 37...

Group-housed male mice exhibit aggressive behaviour towards their cage mates and form a social hierarchy. Here, we describe how social hierarchy in standard group-housed conditions affects behaviour and gene expression in male mice. Four male C57BL/6 mice were kept in each cage used in the study, and the social hierarchy was determined from observation of video recordings of aggressive behaviour. After formation of a social hierarchy, the behaviour and hippocampal gene expression were analysed in the mice. Higher anxiety- and depression-like behaviours and elevated gene expression of hypothalamic corticotropin-releasing hormone and hippocampal serotonin receptor subtypes were observed in subordinate mice compared with those of dominant mice...

Fatigue and low energy are cardinal symptoms of major depressive disorder (MDD) that have an impact on work functioning. Antidepressants with noradrenergic activity have been hypothesized to improve symptoms of fatigue and low energy. We examined the impact of these symptoms on work functioning in patients with MDD treated with the serotonin and noradrenaline reuptake inhibitor, desvenlafaxine. A secondary analysis was carried out from a study of employed adult outpatients (n=35) with MDD and subjective cognitive complaints treated with desvenlafaxine 50-100 mg/day for 8 weeks...

Ginsenoside Rg3 (Rg3), a major active ingredient enriched in red ginseng, possesses well-confirmed immunoregulatory effects. Immune disturbance is a common trigger and aggravating factor of depression. The aim of this study was to explore the effects of Rg3 on lipopolysaccharide (LPS)-induced depression-like behavior in mice and the involvement of immune regulation. Pretreatment with Rg3 (i.g., 20 and 40 mg/kg) effectively ameliorated LPS (i.p., 0.83 mg/kg) induced body weight loss, anorexia, and immobility time in both the tail suspension test and the forced swimming test...

The prevalence of neuropsychiatric disorders following traumatic brain injury (TBI) is 20%-50%, and disorders of mood and cognition may remain even after recovery of neurologic function is achieved. Selective serotonin reuptake inhibitors (SSRI) block the reuptake of serotonin in presynaptic cells to lead to increased serotonergic activity in the synaptic cleft, constituting first-line treatment for a variety of neurocognitive and neuropsychiatric disorders. This review investigates the utility of SSRIs in treating post-TBI disorders...

The serotonin transporter (5-HTT) regulates serotonin homeostasis and has been used as a target for different drugs in depression treatment. Although the serotonergic system has received a lot of attention, little is known about the effects of these drugs over serotonin transporters. In this work, we investigated the expression pattern of 5-HTT during development of the visual system and the influence of fluoxetine on different signaling pathways. Our data showed that the expression of 5-HTT has a gradual increase from postnatal day 0 until 42 and decrease afterwards...

In healthy humans, both childhood trauma and the short form of the serotonin promoter transporter genotype (5-HTTLPR) are associated with lower levels of brain-derived neurotrophic factor (BDNF). In subjects with bipolar disorder (BD), lower levels of BDNF and a higher degree of childhood trauma were observed compared with healthy controls. However, is still unknown if the functional 5-HTTLPR polymorphisms exerts an effect on both abnormalities. In 40 inpatients affected by a major depressive episode in the course of BD, we genotyped 5-HTTLPR, measured serum BDNF with ELISA, and assessed early adversities by the childhood trauma questionnaire (CTQ)...

Various neurological and psychiatric diseases lead to alterations in cortical serotonergic activity as one of their underlying processes. However, the electrophysiological implication of changes in serotonergic activity remains a matter of investigation. In this study, we investigated whether brain serotonergic activity influences the excitability-related phenomenon known as cortical spreading depression (CSD). CSD parameters (propagation velocity, and amplitude and duration of the DC-shift) was evaluated in rats that received two treatments that increased cortical serotonergic activity, electrical stimulation of the raphe nuclei and subcutaneous injection of a selective serotonin reuptake inhibitor, sumatriptan...
