PURPOSE: To determine hippocampal subfields volume loss in depression, which was simulated by a rat chronic unpredictable mild stress (CUMS) model. As different cellular and molecular characteristics in hippocampal subfields, these subfields are regarded as differentially vulnerable to processes associated with stress. MATERIALS AND METHODS: Twenty male Wistar rats were exposed to various stressors until the model was successfully established. The effects of physical exercise on recovery of hippocampal volume in depressed rats were simulated using the wheel running test (WRT)...

Deidre J Smith, Jerome Sarris, Nathan Dowling, Manjula O'Connor, Chee H Ng
OVERVIEW: Whilst the majority of evidence supports the adjunctive use of eicosapentaenoic acid (EPA) in improving mood, to date no study exists using low-dose docosahexaenoic acid (DHA) alone as an adjunctive treatment in patients with mild to moderate major depressive disorder (MDD). METHODS: A naturalistic 8-week open-label pilot trial of low-dose DHA, (260 mg or 520 mg/day) in 28 patients with MDD who were non-responsive to medication or psychotherapy, with a Hamilton Depression Rating Scale (HAM-D) score of greater than 17, was conducted...

REVIEW
D A Slattery, J F Cryan
RATIONALE: Despite substantial research efforts the aetiology of major depressive disorder (MDD) remains poorly understood, which is due in part to the heterogeneity of the disorder and the complexity of designing appropriate animal models. However, in the last few decades, a focus on the development of novel stress-based paradigms and a focus on using hedonic/anhedonic behaviour have led to renewed optimism in the use of animal models to assess aspects of MDD. OBJECTIVES: Therefore, in this review article, dedicated to Athina Markou, we summarise the use of stress-based animal models for studying MDD in rodents and how reward-related readouts can be used to validate/assess the model and/or treatment...

Finasteride has proved to be relatively safe and effective in the therapeutic management of male androgenic alopecia. However, literature data report several endocrine imbalances inducing various adverse effects, which often persist after treatment cessation in the form of post-finasteride syndrome. Here we present the case of a 52-year-old man receiving finasteride (1 mg/day) who developed an uncommon adverse effect represented by generalized vitiligo 2 months after finasteride discontinuation. Associated adverse effects encountered were represented by mild sexual dysfunction (as determined by the International Index of Erectile Function, IIEF) and moderate depressive symptoms (according to DSM-V criteria), all of these manifestations aggregating within/as a possible post-finasteride syndrome...

The increasing cases of depression has made the searches for new drugs and understanding of the underligning neurobiology of this psychiatric disorder a necessity. Here, we modified the structure of salvinorin A (a known halucinogen) and investigated antidepressant-like activity of its four derivatives; 22-methylsulfanylsalvinorin A(SA1), 2-O-cinnamoylsalvinorin B (CSB), 22-azidosalvinorin A (SA2), and 2-O-(4(')-azidophenylsulfonyl)salvinorin B (SA3). Prior to behavioural tests (Irwin test, open field test - OFT, forced swimming test - FST and tail suspension test - TST), SA1 was prepared by reacting salvinorin B and methylthioacetic acid with 89% yield; CSB was obtained from the reaction of salvinorin B and cinnamic acid with 92% yield; SA2 was obtained from the reaction of salvinorin B and azidoacetic acid with 81% yield; and SA3 was prepared by reacting salvinorin B with 4-azidophenylsulfonyl chloride with 80% yield...

Surgical re-implantation of the left coronary artery (LCA) is the treatment of choice in anomalous origin of left coronary artery from pulmonary artery (ALCAPA). Despite normalization of left ventricular function after surgery, residual coronary lesions or myocardial fibrosis may be found. The aim of this study was to detect regional left ventricular dysfunction predictive of coronary lesions or residual myocardial fibrosis using speckle tracking. We enrolled ten patients treated with surgical re-implantation of LCA for ALCAPA...

Ferulic acid is a hydroxycinnamic acid that widely presents in plant cell wall components. It has been demonstrated that ferulic acid can attenuate depressive-like behaviors in both forced swimming test and tail suspension test. Considering that depression is an inflammatory related mental disease, our present study was aimed to investigate the role of ferulic acid in the regulation of microglia activation, pro-inflammatory cytokines, nuclear factor kappa B (NF-κB) and nucleotide binding and oligomerization domain-like receptor family pyrin domain-containing 3 (NLRP3) inflammasome in mice exposed to chronic unpredictable mild stress (CUMS)...

Many US veterans of Afghanistan and Iraq have multiple physical and psychiatric problems. A major focus of research has been on determining the effects of mild Traumatic Brain Injury (mTBI), but mTBI is rarely diagnosed in the absence of co-occurring conditions such as blast exposure, post-traumatic stress disorder (PTSD), depression, substance abuse, etc. These potentially interactive psychological and physical conditions produce complex patterns of cognitive, psychological, and physical symptoms that impede civilian reintegration and complicate efficient and effective treatment planning...

The aim of this study was to determine the effects and underlying mechanism of aripiprazole (APZ) augmentation for cilostazol (CLS)-treated post-ischemic stroke mice that were exposed to chronic mild stress (CMS). Compared to treatment with either APZ or CLS alone, the combined treatment resulted in a greater reduction in depressive behaviors, including anhedonia, despair-like behaviors, and memory impairments. This treatment also significantly reduced atrophic changes in the striatum, cortex, and midbrain of CMS-treated ischemic mice, and inhibited neuronal cell apoptosis, particularly in the striatum and the dentate gyrus of the hippocampus...
