Single-wall carbon nanotubes (SWCNTs) with excellent physicochemical properties are considered a promising candidate for the electrical and mechanical reinforcements of polymers. However, the poor dispersion of SWCNTs in plastics seriously limits their application and their achieved performance enhancement. Here, we coat a freestanding, highly conductive SWCNT film onto the surface of a polyethylene terephthalate (PET) film by a hot-pressing method.

Schizophrenia is a severe and debilitating psychiatric disorder of unknown etiology, and its diagnosis is essentially based on clinical symptoms. Despite growing evidence on the relation of altered expression of miRNAs and schizophrenia, most patients with schizophrenia usually had an extensive antipsychotic treatment history before miRNA expression profile analysis, and the pharmacological effects on miRNA expression are largely unknown. To overcome these impediments, miRNA microarray analysis was performed in peripheral blood mononuclear cells (PBMCs) obtained from patients with schizophrenia who were not on antipsychotic medication and healthy controls.

This study investigated the correlation between the level of microRNA expression in peripheral blood mononuclear cells (PBMCs) and symptomatology in patients with generalized anxiety disorder (GAD). MicroRNA array was performed in peripheral blood mononuclear cells (PBMCs) obtained from GAD patients with gender, age, ethnicity-matched healthy controls. Then real-time quantitative reverse transcription polymerase chain reaction (qRT-PCR) was used to verify the top 7 miRNAs with the highest fold-change values in 76 GAD patients and 39 healthy controls.

This study aimed to develop a Chinese Mental Resilience Scale. A total of 2500 healthy participants, in two representative samples of the Chinese population, were administered the scale. Exploratory factor analysis, confirmatory factor analysis, and correlation analysis were used to obtain the relevant coefficients and verify the reliability and validity of the scale.

This study aimed to investigate the maladjustment of Asian (Bangladeshi, Pakistani) and African (Nigerian, Namibian, Ghanaian) peacekeepers and its major influence factors. By random cluster sampling, 300 Asian peacekeepers and 271 African peacekeepers were administered the military psychological maladjustment scale (MPMS) and risk factors questionnaire. Investigation at Day 7 and Day 120 into the peacekeeping deployment period indicated that MPMS total score and factor scores of the Asian peacekeepers were significantly lower than those of the African peacekeepers (p < .

Objective: This study aimed to explore the scene-trait coping style of military rescuers in Wenchuan earthquake in an effort to provide scientific evidences for mental intervention program for Chinese military personnel.

Methods: By cluster sampling, a total of 151 military rescuers and 331 control servicemen were administered the military personnel scene-trait coping style scale (MPSTCSS).

Results: All active coping factor scores, and passive coping factor scores of affection, health and economy in the rescuer group were significantly higher than those in control group (P < 0.

This study aimed to investigate the effects of sleep deprivation on serum cortisol level and mental health and explore the correlations between them in servicemen. A total of 149 out of the 207 Chinese servicemen were randomly selected to go through 24hour sleep deprivation, leaving the rest (58) as the control group, before and after which their blood samples were drawn for cortisol measurement. Following the procedure, all the participants were administered the Military Personnel Mental Disorder Prediction Scale, taking the military norm as baseline.

This study aimed to identify the difference of microRNA-7 (miR-7) expression levels between schizophrenia patients and healthy controls and to investigate the regulatory effects of miR-7 on the SHANK3 gene in schizophrenia. miR-7 levels in plasma were detected by quantitative polymerase chain reactions (qPCR) in 50 schizophrenia patients and 50 healthy controls. The hippocampal neuron cell line, HT22, was transfected with lentiviral vector overexpressing or knocking-down miR-7, and the expression levels of SHANK3 mRNA and Shank3 protein were measured by qPCR and immunofluorescence.

Background: Sleep disorder induced by acute stress has always been an important topic for study among the general population. However, the mediating effect of social support between acute stress and sleep disorder has rarely been reported before.

Methods: A total of 2,411 grass-root military personnel were randomly selected by cluster sampling, and administered the Chinese Military Personnel Sleep Disorder Scale, Military Acute Stress Scale and Social Support Rating Scale.

Schizophrenia (SZ) is a debilitating psychotic disorder of unknown etiology, and the diagnosis is essentially based on clinical symptoms. So it is urgent to find an objective and feasible clinical diagnostic index for SZ. MicroRNA array was performed in peripheral blood mononuclear cells (PBMCs) obtained from young SZ patients and gender-, age-, and ethnicity-matched healthy controls.

MicroRNAs (miRNA, miR) have been implicated as promising blood-based biomarkers for schizophrenia patients. This study aimed to clinically validate miRNA as potential schizophrenia biomarkers. Plasma levels of 10 miRNAs were analyzed using qPCR in a cohort of 61 schizophrenia patients and 62 normal controls, as well as 25 patients particularly selected for a six-week antipsychotic treatment course.

Findings from multiple studies on microRNA (miRNA) expression profiling in schizophrenia patients have produced conflicting results. In order to investigate miRNA as specific biomarkers in the peripheral plasma and peripheral blood mononuclear cells (PBMC) of schizophrenia patients, expression levels of the nine most frequently reported schizophrenia-associated miRNA (miR-30e, miR-34a, miR-181b, miR-195, miR-346, miR-432, miR-7, miR-132 and miR-212) were examined in the peripheral plasma and PBMC in 25 schizophrenia patients and 13 healthy controls using quantitative real-time reverse transcription polymerase chain reaction. We observed significantly increased expressions of miR-132, miR-195, miR-30e and miR-7 in plasma samples (p<0.

Currently, diagnosis and treatment of major depressive disorder (MDD) are based on the patients' description of symptoms, mental status examinations, and clinical behavioral observations, which increases the chance of misdiagnosis. There is a serious need to find a practical biomarker for the proper diagnosis of MDD. This study aimed to explore the possibility of microRNA (miRNA) in peripheral blood mononuclear cells (PBMCs) as specific blood-based biomarker for MDD patients.

Background: Decreased P300 amplitude is one of the most consistent findings in patients with schizophrenia. However, whether prolonged P300 latency occurs in patients with schizophrenia, especially first-episode schizophrenia (FES) patients, remains controversial.

Methods: A meta-analyses of P300 aberration in FES patients and healthy control(HC) group was conducted.

Despite the growing evidences on the relation of altered expression of miRNAs and schizophrenia, most schizophrenia subjects have an extensive antipsychotic treatment history and the pharmacological effects on miRNA expression are largely unknown. This study aimed to investigate the change of plasma microRNA-181b level and improvement of symptomatology before and after six-week antipsychotic treatment in schizophrenia patients, and explore their association. A total of 20 schizophrenia patients absent of antipsychotics and 20 age-and gender-matched normal controls were enrolled, and tested for 9 schizophrenia-associated microRNA (miR-30e, miR-34a, miR-181b, miR-195, miR-346, miR-432, miR-7, miR-132 and miR-212) expression levels in plasma using quantitative RT-PCR and for symptomatology improvement using Positive And Negative Syndrome Scale (PANSS) before and after treatment (olanzapine, quetiapine, ziprasidone and risperidone) for the patients only.
