The growth of MoO<sub>3</sub> hierarchical plates was obtained by direct resistive heating of molybdenum foil at ambient pressure in absence of any catalysts and templates. Plates synthesized after 60 min resistive heating typically growth in an single-crystalline orthorhombic structure that develop preferentially in [001] direction, as characterized by HRTEM, SAD and Raman-scattering measurements. They are about 100-200nm in thickness and a few tens micrometers in length. As heating time proceeds to 80 min, plates of α-MoO<sub>3</sub> form a branched structure...

Anxiety and depression diagnoses are associated with suicidal thoughts and behaviours. However, a categorical understanding of these associations limits insight into identifying dimensional mechanisms of suicide risk. This study investigated anxious and depressive features through a lens of suicide risk, independent of diagnosis. Latent class analysis of 97 depression, anxiety, and suicidality-related items among 616 psychiatric outpatients indicated a 3-class solution, specifically: (1) a higher suicide-risk class uniquely differentiated from both other classes by high reported levels of depression and anxious arousal; (2) a lower suicide-risk class that reported levels of anxiety sensitivity and generalised worry comparable to Class 1, but lower levels of depression and anxious arousal; and (3) a low to non-suicidal class that reported relatively low levels across all depression and anxiety measures...

BACKGROUND: The ability to recognize emotional expression is essential for social interactions, adapting to the environment and quality of life. Emotion recognition is impaired in people with Alzheimer's disease (AD), thus rehabilitation of these skills has the potential to elicit significant benefits. OBJECTIVE: This study sought to establish whether emotion recognition capacity could be rehabilitated in people with AD. METHODS: Thirty-six participants with AD were assigned to one of three conditions: an experimental group (EG) that received 20 sessions of rehabilitation of emotion recognition and 20 sessions of cognitive stimulation therapy (CST), a control group (CG) that received 40 sessions of CST, and a treatment as usual group (TAU)...

Activation of efflux systems and the formation of biofilm are majorly adapted by microbes to resist antimicrobial agents. PPEF (bisbenzimidazole) targeting topoisomerase IA is observed to be an effective bactericidal agent against both Gram-positive and Gram-negative bacterial strains and thus can be developed as potent broad-spectrum antibiotic against MDR strains. PPEF treatment did not cause target specific mutation instead it leads to up-regulation of efflux gene in E. coli K12 as a mechanism of resistance...

BACKGROUND: There is debate about whether the difficulties that children with different degrees of oppositionality (ODD) and callous-unemotional traits (CU) have in processing emotions are global or specific. The aim of this study is to identify difficulties in recognizing emotion (happiness, anger, sadness and fear) through a go/no-go task in children with different levels of ODD and CU traits. METHOD: A total of 320 8-year-old children were assessed through questionnaires filled out by teachers about oppositional defiant symptoms and CU traits and were then distributed into four groups: LowCU-HighODD, HighCU-LowODD, HighCU-HighODD and a comparison group (LowCU-LowODD)...

While the deterioration of insulin-glucose metabolism (IGM), impaired redox homeostasis (IRH), β-amyloid accumulation was reported in Sporadic Alzheimer's Disease (SAD) model, aforementioned factors related to lipoic acid administration and anthropometric indexes (AIs) are not yet studied with integrative approach. β-amyloid accumulation, redox homeostasis biomarkers and AIs are investigated in SAD model. Streptozotocin-induced inhibition of insulin-signaling cascade but not GLUT-2 and GLUT-3 transporters takes a role in β-amyloid accumulation...

Biofilm formation of Staphylococcus aureus is one of the mechanisms of its drug resistance. Anti-biofilm screening of 106 compounds from marine-derived fungi displayed that 12 compounds inhibited S. aureus biofilm formation by > 50% at the concentration of 100 μg/ml, and only secalonic acid D (SAD) and B inhibited by > 90% at 6.25 μg/ml without inhibiting cell growth after 24-hour incubation. Meanwhile, it was found that the double bond between C-1 and C-10 of citrinin derivatives and the C-C connection position of two chromone monomers may be important for their anti-biofilm activities...

Cognitive therapy for social anxiety disorder (SAD) based on the Clark and Wells model emphasizes negative beliefs about the social self and self-consciousness as central causal factors. However, Wells' metacognitive model proposes that metacognitive beliefs are central to pathology universally. The relative importance of cognitive and metacognitive beliefs in the treatment of SAD is therefore an important research question. This study examined change in negative cognitive and negative metacognitive beliefs as independent correlates of symptom improvement in 46 SAD patients undergoing evidence-based treatments...

Functional magnetic resonance imaging (fMRI) studies have shown altered brain dynamic functional connectivity (DFC) in mental disorders. Here, we aim to explore DFC across a spectrum of symptomatically-related disorders including bipolar disorder with psychosis (BPP), schizoaffective disorder (SAD), and schizophrenia (SZ). We introduce a group information guided independent component analysis procedure to estimate both group-level and subject-specific connectivity states from DFC. Using resting-state fMRI data of 238 healthy controls (HCs), 140 BPP, 132 SAD, and 113 SZ patients, we identified measures differentiating groups from the whole-brain DFC and traditional static functional connectivity (SFC), separately...

BACKGROUND: Generalized anxiety disorder (GAD) and social anxiety disorder (SAD) are co-morbid and associated with similar neural disruptions during emotion regulation. In contrast, the lack of optimism examined here may be specific to GAD and could prove an important biomarker for that disorder. METHOD: Unmedicated individuals with GAD (n = 18) and age-, intelligence quotient- and gender-matched SAD (n = 18) and healthy (n = 18) comparison individuals were scanned while contemplating likelihoods of high- and low-impact negative (e...

Poor mental health in adolescents has shown associations with engagement in other risk behaviours. However, evidence of this association in Sub-Saharan Africa, particularly South Africa, is lacking. This study examines the associations between pertinent risk behaviours and feelings of sadness or hopelessness amongst a nationally representative sample of South African school going adolescents. Data was analysed from the South African Youth Risk Behaviour Survey 2011 (n=10,997), a cross-sectional national survey among grades 8-11 school learners...

Medical research is moving toward prevention strategies during prodromal states. Postpartum blues (PPB) is often a prodromal state for postpartum depression (PPD), with severe PPB strongly associated with an elevated risk for PPD. The most common complication of childbearing, PPD has a prevalence of 13%, but there are no widespread prevention strategies, and no nutraceutical interventions have been developed. To counter the effects of the 40% increase in monoamine oxidase A (MAO-A) levels that occurs during PPB, a dietary supplement kit consisting of monoamine precursor amino acids and dietary antioxidants was created...

BACKGROUND: Despite growing evidence for manualized psychodynamic treatments, there is a lack of studies on their transfer to routine practice. This is the first study to examine the effects of an additional training in manualized Short Term Psychodynamic Psychotherapy (STPP) on the outcome in routine psychotherapy for social anxiety disorder (SAD). The study is an extension to a large RCT comparing STPP to Cognitive-Behavioral Therapy of SAD. METHODS: The manualized treatment was designed for a time limited approach with 25 individual sessions of STPP over 6 months...

Adults are capable of predicting their emotional reactions to possible future events. Nevertheless, they systematically overestimate the intensity of their future emotional reactions relative to how they feel when these events actually occur. The developmental origin of this "intensity bias" has not yet been examined. Two studies were conducted to test the intensity bias in preschool children. In the first study, 5-year-olds (N=30) predicted how they would feel if they won or lost various games. Comparisons with subsequent self-reported feelings indicated that participants overestimated how sad they would feel to lose the games but did not overestimate their happiness from winning...

OBJECTIVE: Emotion processing is known to be mediated by a complex network of cortical and subcortical regions with evidence of specialized hemispheric lateralization within the brain. In light of prior evidence indicating that lateralization of cognitive functions (such as language) may depend on normal visual development, we investigated whether the lack of prior visual experience would have an impact on the development of specialized hemispheric lateralization in emotional processing...

Metastasis, the spread and growth of malignant cells at secondary sites within a patient's body, accounts for > 90% of cancer-related mortality. Recently, impressive advances in novel therapies have dramatically prolonged survival and improved quality of life for many cancer patients. Sadly, incidence of brain metastatic recurrences is fast rising, and all current therapies are merely palliative. Hence, good experimental animal models are urgently needed to facilitate in-depth studies of the disease biology and to assess novel therapeutic regimens for preclinical evaluation...

We investigated the role of self-focused attention (SFA) in social anxiety (disorder) in an ecologically valid way. In Experiment 1 high (n = 26) versus low (n = 25) socially anxious single women between 18 and 30 years had a video ("Skype") conversation with an attractive male confederate, while seeing themselves and the confederate on-screen. The conversation was divided in four phases: (I) warm-up, (II) positive (confederate was friendly to the participant), (III) critical (confederate was critical to the participant), and (IV) active (participant was instructed to ask questions to the confederate)...

The worldwide fascination of da Vinci's Mona Lisa has been dedicated to the emotional ambiguity of her face expression. In the present study we manipulated Mona Lisa's mouth curvature as one potential source of ambiguity and studied how a range of happier and sadder face variants influences perception. In two experimental conditions we presented different stimulus ranges with different step sizes between stimuli along the happy-sad axis of emotional face expressions. Stimuli were presented in random order and participants indicated the perceived emotional face expression (first task) and the confidence of their response (second task)...
