The interplay between subclinical psychotic, negative, and affective symptoms has gained increased attention regarding the etiology of psychosis spectrum and other mental disorders. Importantly, research has tended to not differentiate between different subtypes of psychotic-like experiences (PLE) although they may not have the same significance for mental health. In order to gain information on the subclinical interplay between specific PLE and other symptoms as well as the significance of PLE for mental health, we investigated their specific associations in 206 healthy individuals (20-60 years, 73 females) using correlational and linear regression analyses...

REVIEW
Ro J Robotham, Randi Starrfelt
Face and word recognition have traditionally been thought to rely on highly specialised and relatively independent cognitive processes. Some of the strongest evidence for this has come from patients with seemingly category-specific visual perceptual deficits such as pure prosopagnosia, a selective face recognition deficit, and pure alexia, a selective word recognition deficit. Together, the patterns of impaired reading with preserved face recognition and impaired face recognition with preserved reading constitute a double dissociation...

Recently, the N-methyl-d-aspartate-receptor (NMDAR) antagonist ketamine has emerged as a fast-onset mechanism to achieve antidepressant activity, whereas its psychomimetic, dissociative and amnestic effects have been well documented to pharmacologically model schizophrenia features in rodents. Sleep-wake architecture, neuronal oscillations and network connectivity are key mechanisms supporting brain plasticity and cognition, which are disrupted in mood disorders such as depression and schizophrenia. In rats, we investigated the dynamic effects of acute and chronic subcutaneous administration of ketamine (2...

BACKGROUND: Infantile esotropia is a convergent strabismus presenting before 6 months of age and is the most common strabismus disorder presenting in the ophthalmology OPD. The dilemma of whether to go for early surgery and how early has been a matter of research for the last 50 years. We describe our results of surgery in infantile esotropia at variable age groups, as well as with different reoperation rates and compare with the results in western literature. METHODS: A prospective study was carried out through a review of 113 cases operated for infantile esotropia between February 2013 and August 2014...

The high comorbidity among neuropsychiatric disorders suggests a possible common neurobiological phenotype. Resting-state regional cerebral blood flow (CBF) can be measured noninvasively with magnetic resonance imaging (MRI) and abnormalities in regional CBF are present in many neuropsychiatric disorders. Regional CBF may also provide a useful biological marker across different types of psychopathology. To investigate CBF changes common across psychiatric disorders, we capitalized upon a sample of 1042 youths (ages 11-23 years) who completed cross-sectional imaging as part of the Philadelphia Neurodevelopmental Cohort...

Patients receiving ketamine for refractory depression and anxiety report dissociative symptoms in the first 60 min post-dose. The most commonly used instrument to assess this is the Clinician-Administered Dissociative States Scale (CADSS), developed based on the assessment of patients with dissociative symptoms. Its psychometric properties for ketamine-induced dissociation have not been reported. We evaluated these from a study using 0.25-1 mg/kg ketamine and midazolam (as an active control) in 18 patients with treatment-resistant anxiety...

Oxygen and sulfur co-doped semicrystalline graphitic carbon nitride (HGCNOS) was synthesized by a one-pot hydrothermal method and applied in visible-light photocatalytic nitrogen fixation. Remarkably, HGCNOS exhibited a higher photocatalytic activity than pristine graphitic carbon nitride (GCN). Oxygen doping caused semicrystalline structure, making exciton dissociated at the order-disorder interfaces of HGCNOS and releasing more electrons and holes. Furthermore, the conduction band position of HGCNOS was elevated by sulfur doping, promoting the reduction ability of HGCNOS...

This study examined the roles of posttraumatic stress (PTS) symptoms and dissociation in the relationship between childhood trauma and two different types of psychosis-like experience, including persecutory ideation and aberrant experience, in non-psychotic psychiatric patients. From August 2015 to August 2016, among psychiatric out patients seeking treatment at the Department of Psychiatry at a major teaching medical hospital in Seoul, Korea, 169 patients who had never been diagnosed with a psychotic disorder, including schizophrenia spectrum disorder, bipolar disorder, and/or depressive disorder with psychotic features, completed the Korean Childhood Trauma Questionnaire, the Korean version of the Impact of Event Scale-Revised, the modified Korean version of the Peritraumatic Dissociation Experiences Questionnaire, and the Korean Minnesota Multiphasic Personality Inventory-2 (MMPI-2)...

In mammals, STAT3 (Signal transducer and activator of transcription 3) plays an important role in growth, multiplication, differentiation and participates in inflammation, tumorigenesis, metabolic disorders and immune response. STAT3 is a protein that shuttles between the nucleus and cytoplasm. Compared to the STAT3 in cell nucleus, we did not know the function of STAT3 in cytoplasm for a long time. Some recent studies have shown that cytoplasmic STAT3 regulates autophagy through the interaction with the double-stranded RNA-activated protein kinase (PKR), which plays an important role in cellular antiviral response...

This study examined shame and responses to it in adult dissociative disorder (DD; n = 24) and comparison psychiatric (n = 14) samples. To investigate how helpful different therapeutic responses are after shame disclosures in therapy, participants heard two vignettes from "mock" patients disclosing a) shame and b) surprise. Participants rated the helpfulness of five potential responses. Interventions covered withdrawing from the affect (withdrawal focused) to feeling it (feeling focused), with other interventions on cognitions (cognitive focused), management strategies (management focused), and previous experiences (history focused)...

BACKGROUND: The vestibular system integrates multisensory information to monitor one's bodily orientation in space, and is influenced by interoceptive awareness. Post-traumatic stress disorder (PTSD) involves typically alterations in interoceptive and bodily self-awareness evidenced by symptoms of hyperarousal, as well as of emotional detachment, including emotional numbing, depersonalization, and derealization. These alterations may disrupt vestibular multisensory integration between the brainstem (vestibular nuclei) and key vestibular cortical regions (parieto-insular vestibular cortex, prefrontal cortex)...

Performance deficits on the Wisconsin Card Sorting Test (WCST) in patients with prefrontal cortex (PFC) lesions are traditionally interpreted as evidence for a role of the PFC in cognitive flexibility. However, WCST deficits do not occur exclusively after PFC lesions, but also in various neurological and psychiatric disorders. We propose a multi-component approach that can accommodate this pattern of omnipresent WCST deficits: the WCST is not a pure test of cognitive flexibility, but relies on the effective functioning of multiple dissociable cognitive components...

Interoception has been defined as the sensing of the physiological condition of the body, with interoceptive sensibility (IS) characterizing an individual's self-reported awareness of internal sensation. IS is a multidimensional construct including not only the tendency to be aware of sensation but also how sensations are interpreted, regulated, and used to inform behavior, with different dimensions relating to different aspects of health and disease. Here we investigated neural mechanisms of interoception when healthy individuals attended to their heartbeat and skin temperature, and examined the relationship between neural activity during interoception and individual differences in self-reported IS using the Multidimensional Scale of Interoceptive Awareness (MAIA)...

The ability to adaptively regulate responses to the proximity of potential danger is critical to survival and imbalance in this system may contribute to psychopathology. The bed nucleus of the stria terminalis (BNST) is implicated in defensive responding during uncertain threat anticipation whereas the amygdala may drive responding upon more acute danger. This functional dissociation between the BNST and amygdala is however controversial, and human evidence scarce. Here we utilized data from two independent functional magnetic resonance imaging studies (N=108 males & N=70 (45 females)) to probe how coordination between the BNST and amygdala may regulate responses during shock anticipation and actual shock confrontation...

MED26 is a subunit of Mediator, a large complex central to the regulation of gene transcription by RNA Polymerase II (RNA Pol II). MED26 plays a role in the switch between the initiation and elongation phases of RNA Pol II-mediated transcription process. Regulation of these steps requires successive binding of MED26 N-Terminal domain (NTD) to TBP-associated factor 7 (TAF7) and EAF1 (Eleven-nineteen lysine-rich in leukemia-Associated Factor 1). In order to investigate the mechanism of regulation by MED26, MED26-NTD structure was solved by nuclear magnetic resonance spectroscopy (NMR), revealing a 4-helix bundle...

Disruption of oxidant/anti-oxidant ratio as well as endoplasmic reticulum (ER) stress are thought to be involved in the pathophysiology of schizophrenia. These stresses can lead to impairments in brain functions progressively leading to neuronal inflammation followed by neuronal cell death. Moreover, the cellular stresses are interlinked leading us to the conclusion that protein misfolding, oxidative stress and apoptosis are intricately intertwined events requiring further research into their mechanistic and physiological pathways...

Adverse childhood experiences (ACE) substantially increase the risk of later psychiatric and somatic pathology. While neurobiological factors are likely to play a mediating role, specific insights are lacking. The scarce neuroimaging studies in traumatised pediatric populations have provided inconsistent results, potentially due to the inclusion of different types of trauma. To further improve our understanding of the neurobiology of pediatric psychotrauma, this study seeks to investigate abnormalities in grey matter volume (GMV) in a homogeneous group of adolescents with posttraumatic stress disorder (PTSD) due to childhood sexual abuse (CSA) and the relationship between GMV and symptom severity...
