In this paper we present, for the first time, a detailed account of electrophysiological effects of 2,4-diaminobutyric acid (2,4-DABA). 2,4-DABA is a neurotoxic non-protein amino acid produced by Cyanobacteria with a possible link to neurodegenerative disorders in animals and humans. Intracellular recordings were performed on Retzius nerve cells of the leech Haemopis sanguisuga using glass microelectrodes filled with 3 mol/L KCl. Our results show that 2,4-DABA is an excitatory amino acid, causing membrane depolarization in a concentration-dependent manner...

BACKGROUND: Neuroimaging studies have demonstrated gray matter (GM) volume abnormalities in substance users. While the majority of substance users are polysubstance users, very little is known about the relation between GM volume abnormalities and polysubstance use. METHODS: In this study we assessed the relation between GM volume, and the use of alcohol, tobacco, cocaine and cannabis as well as the total number of substances used, in a sample of 169 males: 15 non-substance users, 89 moderate drinkers, 27 moderate drinkers who also smoke tobacco, 13 moderate drinkers who also smoke tobacco and use cocaine, 10 heavy drinkers who smoke tobacco and use cocaine and 15 heavy drinkers who smoke tobacco, cannabis and use cocaine...

Colony stimulating factor-1 (CSF-1) is one of the most common proinflammatory cytokine responsible for various inflammatory disorders. It has a remarkable role in the development and progression of osteoarthritis, cancer and other autoimmune disease conditions. The CSF-1 acts by binding to the receptor, called colony stimulating factor-1 receptor (CSF-1R) also known as c-FMS resulting in the cascade of signalling pathway causing cell proliferation and differentiation. Interleukin-34 (IL-34), recently identified as another ligand for CSF-IR, is a cytokine protein...

BACKGROUND: Eveningness may be defined as the tendency to be most active and alert during the evening. Previous research has linked eveningness with maladaptive psychological outcomes, and recent evidence has highlighted circadian dysregulation as a novel factor in psychopathology, including obsessive-compulsive disorder (OCD). However, limited research has examined the unique relationship between eveningness and OC symptoms. Two studies were conducted to thoroughly examine the links between eveningness and OC symptoms, while also considering the role of depression symptoms and sleep-related factors...

Recognizing others' emotions is a fundamental social skill, widely impaired in psychiatric populations. These emotional dysfunctions are involved in the development and maintenance of alcohol-related disorders, but their differential intensity across emotions and their modifications during disease evolution remain underexplored. Affective prosody decoding was assessed through a vocalization task using six emotions, among 17 patients with severe alcohol use disorder, 16 Korsakoff syndrome patients (diagnosed following DSM-V criteria) and 19 controls...

Deficits in empathy seen in schizophrenia are thought to play a major role in the social dysfunction seen in the disorder. However, little work has investigated potential determinants of empathic deficits. This study aimed to fill that gap by examining the effects of two variables on empathy - distress tolerance and metacognitive self-reflectivity. Fifty-four people with schizophrenia-spectrum disorders receiving services at an urban VA or community mental health center were assessed for empathy, metacognition, and distress tolerance...

BACKGROUND: Endocrine treatment (ET) with an aromatase inhibitor (AI) is the treatment of choice in post-menopausal patients with hormone receptor-positive early breast cancer (EBC). However, adverse events (AEs) often lead to treatment discontinuation. This analysis aimed to identify side-effects that lead to patients failing to persist with letrozole treatment. PATIENTS AND METHODS: Post-menopausal hormone receptor-positive EBC patients starting ET with letrozole were enroled in EvAluate-TM, a non-interventional study...

BACKGROUND: Mindfulness-based relapse prevention (MBRP) is a method that combines cognitive behavioral relapse prevention with mindfulness practice. Research shows that MBRP can effectively reduce negative emotions and craving in people with substance use disorders (SUDs). An important part of MBRP is to practice mindfulness meditation to cope with high-risk situations for relapse, such as stimuli and situations associated with drug taking. Virtual reality cue exposure (VRCE) may be a complementary approach to MBRP as it allows for controlled and graded presentations of various high-risk situations with distal and proximal drug cues...

BACKGROUND: Compared with total gastrectomy, proximal gastrectomy (PG) has potential advantages from a nutritional perspective, such as anemia and postoperative loss of body weight. However, PG is associated with some postoperative functional disorders, such as reflux esophagus (13-31%) and anastomotic stenosis (3-29%).1 We therefore developed a new procedure for fundoplication during esophago-gastrostomy after robotic PG (RPG). METHODS: We performed RPG for early gastric cancer localized in the upper third of the stomach using the da Vinci Surgical System (Intuitive, Sunnyvale, CA)...

Individuals diagnosed with a depressive disorder have been found to show reduced reactions to emotional information consistent with the hypothesis of an emotional context insensitivity. However, there are contradictory findings of enhanced reactivity and mood-congruent processing. Electroencephalography (EEG) recordings of the late positive potential (LPP) can display such blunted or enhanced activity. Due to these contradictory findings, there is a need to clarify the role of the LPP in the emergence and presence of depressive disorders especially in children...

This paper aims to examine consumer perception toward celebrity diagnoses of major depressive disorder (MDD) in Hong Kong and to provide insights into the effect of various factors on the persuasive effectiveness of MDD communication. A total of thirty-five interviews were conducted in April 2015. Interviewees in general are aware of celebrity MDD diagnoses, but they do not deem MDD as a threat to themselves. Hence, they are not motivated to learn more about the symptoms. Responses to celebrity MDD diagnoses are mixed...

PURPOSE OF REVIEW: With a high signal-to-noise ratio, unparalleled spatial resolution, and improved contrasts, ultra-high field MR (≥ 7 T) has great potential in depicting the normal radiological anatomy of smaller structures in the brain and can also provide more information about morphological, quantitative, and metabolic changes associated with a wide range of brain disorders. By focusing attention on specific brain regions believed to be associated with early pathological change, or by more closely inspecting recognized foci of brain pathology, ultra-high field MR can improve the accuracy and sensitivity of neuroimaging...

It is unclear to what extent failure to recognize symptoms as potential sign of a mental illness is impeding service use, and how stigmatizing attitudes interfere with this process. In a prospective study, we followed a community sample of 188 currently untreated persons with mental illness (predominantly depression) over 6 months. We examined how lack of knowledge, prejudice and discrimination impacted on self-identification as having a mental illness, perceived need, intention to seek help, and help-seeking, both with respect to primary care (visiting a general practitioner, GP) and specialist care (seeing a mental health professional, MHP)...

We summarize evidence supporting contemporary pharmacological treatment of phases of BD, including: mania, depression, and long-term recurrences, emphasizing findings from randomized, controlled trials (RCTs). Effective treatment of acute or dysphoric mania is provided by modern antipsychotics, some anticonvulsants (divalproex and carbamazepine), and lithium salts. Treatment of BD-depression remains unsatisfactory but includes some modern antipsychotics (particularly lurasidone, olanzapine + fluoxetine, and quetiapine) and the anticonvulsant lamotrigine; value and safety of antidepressants remain controversial...

While both individual transcription factors and cis-acting sites have been studied in relation to psychiatric disorders, there is little knowledge of the relative contribution of trans-acting and cis-acting factors to gene transcription in the brain. Using an RNA-seq approach in mice bred from two evolutionary-distinct mice strains, we determined the contribution of cis and trans factors to gene expression in the prefrontal cortex and amygdala, two regions of the brain relevant to the stress response, and the contribution of cis and trans factors in the prefrontal cortex after Chronic Social Defeat (CSD) in mice...

INTRODUCTION: Delirium, which is prevalent in postcardiac surgical patients, is an acute brain dysfunction characterised by disturbances in attention, awareness and cognition not explained by a pre-existing neurocognitive disorder. The pathophysiology of delirium remains poorly understood. However, basic science and clinical studies suggest that sleep disturbance may be a modifiable risk factor for the development of delirium. Dexmedetomidine is a α-2A adrenergic receptor agonist medication that patterns the activity of various arousal nuclei similar to sleep...
