Emerging evidence implicates impaired self-regulation of the hypothalamic-pituitary-adrenal (HPA) axis and inflammation as important and closely related components of the pathophysiology of major depression. Antidepressants show anti-inflammatory effects and are suggested to enhance glucocorticoid feedback inhibition of the HPA axis. HPA axis activity is also negatively self-regulated by the adrenocorticotropic hormone (ACTH), a potent anti-inflammatory peptide activating five subtypes of melanocortin receptors (MCRs)...

Studies suggest that the blockade of 5-HT1A, 5-HT7, and 5-HT3 receptor may increase the speed of antidepressant response. 1-[(2,6-Dimethylphenoxy)ethoxyethyl]-4-(2-methoxyphenyl)piperazine hydrochloride (HBK-14) and 1-[(2-chloro-6-methylphenoxy)ethoxyethyl]-4-(2-methoxyphenyl)piperazine hydrochloride (HBK-15), dual 5-HT1A and 5-HT7 antagonists, showed significant antidepressant- and anxiolytic-like properties in our previous tests in rodents. In this study, we aimed to investigate their antidepressant potential using mouse model of corticosterone-induced depression...

RATIONALE: The recruitment of the stress circuitry contributes to a shift from positive to negative reinforcement mechanisms sustaining long-term cocaine addiction. The kappa opioid receptor (KOPr) signaling is upregulated by stress and chronic cocaine exposure. While KOPr agonists induce anhedonia and dysphoria, KOPr antagonists display antidepressant and anxiolytic properties. Most of the knowledge on KOPr antagonism is based on drugs with unusual pharmacokinetic and pharmacodynamic properties, complicating interpretation of results...

This research investigates the psychological well-being and usage of medical treatments by Asian and Hispanic immigrant descendants. Using data from all four waves of Add Health study, this paper focuses on two outcomes: (1) depression and (2) levels of antidepressant use by race/ethnicity, immigrant generation, and linguistic acculturation levels during adulthood. Findings reveal that depression is prevalent among Mexican Americans, other Hispanics, and Asian Americans. Furthermore, Mexican Americans and Asian Americans have reported a lower level of antidepressant use than whites, with Asian Americans attaining the lowest level when immigrant generation, language acculturation levels, and other socioeconomic factors are held constant...

Long-term exposure to stress plays a key role in the pathogenesis of major depression. Recently, the ventrolateral orbital cortex (VLO) has received considerable attention for its role in the antidepressant response. However, the mechanisms underlying stress response in the VLO remain largely elusive. MiR-101 has been implicated in regulating multiple neurological processes. The present study used the chronic unpredictable mild stress (CUMS) rat model to investigate the expression of miR-101 in the VLOs of rat brains and the possible relevance of miR-101 to depression...

Parkinson's disease (PD) is also associated with cognitive impairment and reduced extrinsic supply of dopamine (DA) to the prefrontal cortex (PFC). In the present study, we looked at whether exposure to early life stress reduces DA and serotonin (5-HT) concentration in the PFC thus leading to enhanced cognitive impairment in a Parkinsonian rat model. Maternal separation was the stressor used to develop an animal model for early life stress that has chronic effects on brain and behavior. Sprague-Dawley rats were treated with the antidepressant Fluvoxamine maleate (FM) prior to a unilateral 6-hydroxydopamine (6-OHDA) lesion to model motor deficits in rats...

Psoriasis is a chronic, inflammatory scaling dermatosis. The marked visible appearance of the lesions have a negative impact on body image that leads to decreased self-esteem, hence seriously compromising the patient's quality of life. The clinical picture critically affects the social well-being of the patient since the disease is commonly misunderstood and feared by the social environment as being contagious. The patient feels stigmatized and this further intensifies their lack of self-confidence and self-esteem...

Stigma and mental health literacy affect access to and quality of treatment of major depression. Though mental health professionals seem better able to recognize major depression than the general public, they often hold similarly stigmatizing attitudes towards people suffering from the disorder. These attitudes are shaped jointly by the public stigma attached to mental illnesses as well as by the content and delivery of mental health professionals' undergraduate training. In line with this, the present study aimed to explore psychology students' ability to recognize major depression, their attitudes towards the disorder, and their views surrounding helpfulness of various interventions...

The authors review current advances in the therapy of diabetic neuropathy. The role of glycaemic control and management of cardiovascular risk factors in the prevention and treatment of neuropathic complications are discussed. As further options of pathogenetic ally oriented treatment, recent knowledge on benfotiamine and alpha-lipoic acid is comprehensively reviewed. Alpha-lipoic acid is a powerful antioxidant and clinical trials have proven its efficacy in ameliorating neuropathic signs and symptoms. Benfotiamine acts via the activation of transketolase and thereby inhibits alternative pathways triggered by uncontrolled glucose influx in the cells comprising polyol, hexosamine, protein-kinase-C pathways and formation of advanced glycation end products...

The rapidly-acting antidepressant properties of ketamine are a trend topic in psychiatry. Despite its robust effects, these are ephemeral and can lead to certain adverse events. For this reason, there is still a general concern around the off-label use of ketamine in clinical practice settings. Nonetheless, for refractory depression, it should be an indication to consider. We report the case of a female patient admitted for several months due to a treatment-resistant depressive bipolar episode with chronic suicidal behaviour...
