The current study aimed to develop a biodegradable three-dimensional drug-loaded scaffold with the core-shell structured fibrils using coaxial wet-electrospinning for neural tissue engineering application. Poly lactic acid was wet-electrospun as the core, whereas cellulose acetate was fabricated into the fibril's shell. The scaffold then was coated with citalopram-loaded gelatin nanocarriers (CGNs) produced by nanoprecipitation. Scanning electron microscope observation revealed that the fibrils formed a nonwoven structure with the average diameter of ∼950nm...

BACKGROUND AND PURPOSE: It has recently been suggested that 5-HT3 receptor blockade enhances selective serotonin reuptake inhibitor (SSRI) antidepressants efficacy and may reverse stress-induced deficits in rodents. EXPERIMENTAL APPROACH: To further explore this hypothesis, we used mice lacking the 5-HT3 receptor (Htr3a KO) and their wild-type (WT) controls to assess their response in behavioural paradigms relevant to anxiety and depression. Mice were studied under basal, antidepressant treatments and chronic social defeat stress (CSDS) conditions...

BACKGROUND: Residual symptoms are detrimental to prognosis in major depressive disorder (MDD); however, little is known about the contribution of each residual symptom in predicting outcomes. The objective of this analysis was to identify which individual symptoms, based on self-report and clinician interview, could predict subsequent relapse. METHODS: The data of 1133 outpatients with nonpsychotic MDD who entered a 12-month naturalistic follow-up phase after achieving remission with level 1 treatment (i...

Selective serotonin reuptake inhibitors (SSRI) are common antidepressants which cytotoxicity has been assessed in cancers notably colorectal carcinomas and glioma cell lines. We assessed and compared the cytotoxicity of 2 SSRI, citalopram and escitalopram, on neuroblastoma cell lines. The study was performed on 2 non-MYCN amplified cell lines (rat B104 and human SH-SY5Y) and 2 human MYCN amplified cell lines (IMR32 and Kelly). Citalopram and escitalopram showed concentration-dependent cytotoxicity on all cell lines...

Objective: Human induced pluripotent stem cell-derived cardiomyocytes (hiPSC-CM) may serve as a new assay for drug testing in a human context, but their validity particularly for the evaluation of inotropic drug effects remains unclear. In this blinded analysis, we compared the effects of 10 indicator compounds with known inotropic effects in electrically stimulated (1.5 Hz) hiPSC-CM-derived 3 dimensional engineered heart tissue (EHT) and human atrial trabeculae (hAT). Methods and results: Human EHTs were prepared from iCell® hiPSC-CM, hAT obtained at routine heart surgery...

REVIEW
T W Robbins
This Review advances the case that bidirectional, cross-species translation of findings from experimental animals to and from humans is an important strategy for drug discovery. Animal models of mental disorders require appropriate behavioural or cognitive outcome variables that can be generalized cross-species. One example is the treatment of impulsive behaviour in attention deficit hyperactivity disorder (ADHD) with stimulant drugs. Performance on the stop signal reaction task as an index of impulsivity is improved both in healthy human volunteers and in patients with adult ADHD by stimulant drugs and also by the selective noradrenergic reuptake blocker atomoxetine...

BACKGROUND: Citalopram hydrobromide (CTL) has been shown to cause sexual dysfunction; however, its reproductive toxicity potential has not been sufficiently elucidated in men. Therefore, we aimed to clarify the toxic effects of CTL on the reproductive system of male rats. METHODS: For this purpose, CTL was administered at 5, 10, and 20 mg/kg/day to rats orally for 28 days. Sperm concentration, motility, and morphology were investigated using a computer-assisted sperm analysis system, and sperm DNA damage was detected using a Comet assay...

Citalopram, mirtazapine and risperidone are frequently prescribed for psychiatric illnesses such as depression and psychosis or for aggressive behavior in elderly patients with dementia. The plasma concentrations vary greatly between patients, especially in elderly patients. Thus, therapeutic drug monitoring (TDM) increases the safety of antipsychotic treatment and a more rapid response to treatment may be achieved. To facilitate TDM, the objectives of this study were to develop and validate a reliable dried blood spot method to simultaneously quantify citalopram, mirtazapine and risperidone including its active metabolite 9-hydroxyrisperidone...

Aims and method To discern changes in body mass index (BMI) in patients on long-term antidepressant treatment in a general practice population and establish BMI changes in patients with and without a diagnosis of diabetes. We used a retrospective observational method and identified patients on four antidepressants of interest. We excluded those who did not have start and current BMI readings within the past 3 years and noted whether or not patients had a diagnosis of diabetes. Results Long-term treatment with citalopram, fluoxetine, mirtazapine and sertraline was associated with increased BMI in two-thirds of patients...

The serotonin transporter (SERT) mediates Na(+)-dependent high-affinity serotonin uptake and plays a key role in regulating extracellular serotonin concentration in the brain and periphery. To gain novel insight into SERT regulation, we conducted a comprehensive proteomics screen to identify components of SERT-associated protein complexes in the brain by employing three independent approaches. In vivo SERT complexes were purified from rat brain using an immobilized high-affinity SERT ligand, amino-methyl citalopram...

Background: Patients on the selective serotonergic re-uptake inhibitors (SSRI) like citalopram report emotional blunting. We have shown previously that citalopram reduces resting-state functional connectivity (RSFC) in healthy volunteers in a number of brain regions including the dorso-medial prefrontal cortex, which may be related to its clinical effects. Bupropion is a dopaminergic and noradrenergic re-uptake inhibitor (DNRI) and is not reported to cause emotional blunting. However how bupropion affects RSFC in healthy controls remains unknown...
