During exposure to chronic stress, some individuals engage in active coping behaviors that promote resiliency to stress. Other individuals engage in passive coping that is associated with vulnerability to stress and with anxiety and depression. In an effort to identify novel molecular mechanisms that underlie vulnerability or resilience to stress, we used nonbiased analyses of microRNAs in the ventral hippocampus (vHPC) to identify those miRNAs differentially expressed in active (long-latency (LL)/resilient) or passive (short-latency (SL)/vulnerable) rats following chronic social defeat...

BACKGROUND: Impaired cognition is one of the most common core symptoms of depressive disorder. Eye movement testing mainly reflects patients' cognitive functions, such as cognition, memory, attention, recognition, and recall. This type of testing has great potential to improve theories related to cognitive functioning in depressive episodes as well as potential in its clinical application. AIMS: This study investigated whether eye movement indices of patients with unmedicated depressive disorder were abnormal or not, as well as the relationship between these indices and mental symptoms...

LH-21 is a triazol derivative that has been described as a low-permeant neutral CB1 antagonist, though its pharmacology is still unclear. It has been associated with anti-obesity actions in obese rats. However, its role in preventing type 2 diabetes (T2D) onset have not been studied yet. Given CB1 receptors remain as potential pharmacological targets to fight against obesity and T2D, we wanted to explore the metabolic impact of this compound in an animal model of obesity and pre-diabetes as well as the lack of relevant actions in related central processes such as anxiety...

A recent article by Farrell et al. characterizes the phenomenon, mechanisms, and treatment of a local and severe hypoperfusion/hypoxia event that occurs in brain regions following a focal seizure. Given the well-established role of cerebral ischemia/hypoxia in brain damage and behavioral dysfunction in other clinical settings (e.g., stroke, cerebral vasospasm), we put forward a new theory: postictal hypoperfusion/hypoxia is responsible for the negative consequences associated with seizures. Fortunately, inhibition of two separate molecular targets, cyclooxygenase-2 (COX-2) and l-type calcium channels, can prevent the expression of postictal hypoperfusion/hypoxia...

Glyoxalase 1 (Glo1) is the first enzyme involved in glutathione-dependent detoxification of methylglyoxal, eventually generating d-lactate by the second enzyme glyoxalase 2 (Glo2). An accumulation of intracellular glyoxal and methylglyoxal leads to protein malfunction and mutation via formation of the advanced glycation end products (AGEs). Studies on mouse behavior suggest that methylglyoxal has anxiolytic properties. In this report, we generated and characterized a mouse knockout for Glo1. The knockout mice were viable without a pronounced phenotypic defect...

The article discusses the pathogenetic mechanisms of anxiety in different psychiatric disorders. The influence of anxiety on the course, pharmacotherapeutic treatment with respect to the pathogenesis and the possible neurochemical imbalance in the definite type of anxiety are discussed. An anti-anxiety effect in the action of psychotropic drugs is described. It is proposed that neurochemical disturbances are not the same with the various types of anxiety, which requires using drugs from various groups to achieve treatment of the symptom on the pathogenetic level...

Systemic lupus erythematosus (SLE) is an incurable autoimmune disease characterized by autoantibody deposition in tissues such as kidney, skin and lungs. Notably, up to 75% of patients with SLE experience neuropsychiatric symptoms that range from anxiety, depression and cognitive impairment to seizures and, in rare cases, psychosis-collectively this is referred to as central nervous system (CNS) lupus. In some cases, certain autoantibodies, such as anti-NMDAR or anti-phospholipid antibodies, promote CNS lupus...

BACKGROUND: Current treatments of panic disorder (PD) are limited by adverse effects, poor efficacy, and need for chronic administration. The established safety profile of subanesthetic concentrations of xenon gas, which is known to act as a glutamate subtype NMDA receptor antagonist, coupled with preclinical studies demonstrating its effects in other anxiety related conditions, prompted us to evaluate its feasibility and efficacy in treatment of patients with PD. METHODS: An open-label clinical trial of xenon-oxygen mixture was conducted in 81 patients with PD; group 1 consisting of patients only with PD (N = 42); and group 2 patients with PD and other comorbidities (N = 39)...

Post-traumatic stress disorder (PTSD) is a chronic psychiatric disorder, characterized by intense fear, and increased arousal and avoidance of traumatic events. The current available treatments for PTSD have limited therapeutic value. Genistein, a natural isoflavone, modulates a variety of cell functions. In this study, we tested anti-anxiety activity and underlying mechanisms of genistein in a PTSD rat model. The rats were trained to associate a tone with foot shock delivery on day 0, then fear conditioning was performed on day 7, 14 and 21...

Ribosomal s6 kinase 2 is a growth factor activated serine/threonine kinase and member of the ERK signaling pathway. Mutations in the Rsk2 gene cause Coffin-Lowry syndrome, a rare syndromic form of intellectual disability. The Rsk2 KO mouse model was shown to have learning and memory defects. We focused on the investigation of the emotional behavioral phenotype of Rsk2 KO mice mainly in the IntelliCage. They exhibited an anti-depressive, sucrose reward seeking phenotype and showed reduced anxiety. Spontaneous activity was increased in some conventional tests...

BACKGROUND: Adiponectin is an anti-inflammatory, insulin-sensitizing and energy-regulating adipocytokine. Consequently, the link between psychosocial stress and inflammatory diseases like the metabolic syndrome might be partially explained by lower adiponectin levels in stress. Nevertheless, the stress-adiponectin association has seldom been tested and no clarity exists about the directionality. METHODS: In the Belgian ChiBS study, serum adiponectin and stress levels were measured in 348 children (5-10y) at baseline and in 168 of them after 2-year follow-up...

Theanine, an amino acid in tea, has significant anti-stress effects on animals and humans. However, the effect of theanine was blocked by caffeine and gallate-type catechins, which are the main components in tea. We examined the anti-stress effect of green tea with lowered caffeine, low-caffeine green tea, on humans. The study design was a single-blind group comparison and participants (n=20) were randomly assigned to low-caffeine or placebo tea groups. These teas (≥500 mL/d), which were eluted with room temperature water, were taken from 1 week prior to pharmacy practice and continued for 10 d in the practice period...

Depressive symptoms are common in multiple sclerosis (MS), and both depression and MS have been associated with a poor vitamin D status. As cytokine-mediated inflammatory processes play a role in the pathogenesis of both disorders, we hypothesized that vitamin D3 supplementation reduces depressive symptoms in MS via its immunomodulatory properties. In this randomized pilot study relapsing remitting (RR) MS patients received either vitamin D3 supplementation (n=20; 14.000IU/day) or placebo (n=20) during 48weeks...

Alzheimer's disease (AD) is an age-related neurodegenerative disorder characterized by a progressive cognitive impairments and chronic inflammation that affects over 30 million people all over the world. Most of Alzheimer's patients also suffer from psychosis, aggression, agitation, depression, anxiety, and many other behavioral and psychological symptoms of dementia. Unfortunately, currently available anti-AD drugs provide modest symptomatic relief, and do not reverse the neurodegeneration. Consequently, the average life expectancy after diagnosis is between six to ten years...
