    Abstract: Sequential sorption of bovine serum albumin (BSA)–humic acid (HA)–BSA on weakly ferromagnetic maghemite nanoparticles has achieved the formation of amyloid scaffold-controlled self-assembly (B2-GFeNPs) at pH 4. Unlike BSA-modified maghemite (B1-GFeNPs), which has stronger magnetic dipolar interaction-mediated random aggregation, the liquid crystalline nature and nanoconfinement effects of the amyloid scaffold controlled the growth of highly ordered colloidal assemblies of B2-GFeNPs. These assembled structures undergo topotactic transformations due to Helfrich membrane bending when the suspension pH is increased from 4 to 7. In the presence of an external magnetic field, and at pH 4 these self-assembled structures underwent screw dislocation-driven growth; for example, nanowires and helicoidal and disc-like colloidal crystals. The formations of micropipe-like open core screw defects with a higher magnitude of the Burgers vector of the colloidal clusters were also observed. The interaction of Pb 2+ (0–100 μg L −1 ) within the amyloid backbone of B2-GFeNP clusters at pH 4 produced an FCC-like geometry and resulted in moderate to severe plastic deformation, including slip, with increasing concentrations of heavy metal ions. The signatures of plastic deformation, including dislocation dipoles, prismatic loops, stacking fault tetrahedra, and twin boundaries were observed. At pH 7, the topological transformation of B2-GFeNPs and Pb 2+ -induced elastic strain caused a dislocation pile-up, which represented the zincblende {111} face. The dislocation reactions produced from the mutual interactions between the Shockley partials (which evolved from the stacking faults) with Burgers vectors and that moved along {111} planes resulted in the formation of a Lomer–Cottrell (LC) barrier with a stair-rod geometry. Therefore, Fe–NOM coprecipitate interactions with heavy metal ions or soil colloids isolated from metal-contaminated soils may provide the morphological signatures of elastic strain-mediated geometries.

    Abstract: A novel hypothesis in cancer biology proposes that cancer growth is driven by cancer stem-like cells (CSLCs), also called tumor-initiating cells, which can self-renew and differentiate into multilineage progeny in a fashion similar to stem cells. However, the impact and underlying mechanisms of this process in lung adenocarcinoma (LAC) remain to be elucidated. Here, we report that microRNA-214 (miR-214) contributes to cell self-renewal by directly targeting catenin beta interacting protein 1 (CTNNBIP1), a member of the Wnt signaling pathway. We demonstrate that miR-214 overexpression enhances stem-like properties in LAC cells and that miR-214 shows increased expression in CSLCs derived from primary tumor tissue and from two LAC cell lines (A549 and NCI-H1650). Strikingly, downregulation of miR-214 expression in CSLCs resulted in a significant decrease in spheroid formation and the expression of the stem-cell markers Nanog, Oct-4, and Sox-2. Finally, CTNNBIP1 was identified as a target of miR-214. miR-214 expression in LAC was negatively correlated with CTNNBIP1 expression and positively correlated with differentiated cellular states. Moreover, CTNNBIP1 expression correlated with longer overall survival in LAC patients. This study reveals that miR-214 plays a critical role in CSLC self-renewal and stemness by targeting CTNNBIP1. The identification of this functional miR-214-CTNNBIP1 interaction that regulates self-renewal in CSLCs has the potential to direct the development of novel therapeutic strategies for LAC.

    Abstract: Dopamine-β-hydroxylase (DβH) is an enzyme converting dopamine to norepinephrine, a key neurotransmitter in mood disorders, such as major depressive disorder (MDD) and bipolar disorder (BD). Due to overlapping symptomology of unipolar and bipolar depression, the present study attempted to explorer if the plasma DβH activity could discriminate the depressive episodes of BD from MDD. The aim of this study was to compare the plasma DβH activity among MDD patients ( n = 104), BD patients ( n = 101), and healthy controls ( n = 160). Clinical characteristics and cognitive function were assessed using the Young Mania Rating Scale (YMRS), Hamilton Depression Scale (HAM-D), Hamilton Anxiety Scale (HAM-A), Patient Health Questionnaire-9 (PHQ-9), and Repeatable Battery for the Assessment of Neuropsychological Status (RBANS). Our data showed a lower plasma DβH activity in patients with BD, not MDD, than that in controls. For the BD patients, the plasma DβH activities were negatively correlated with HAM-D scores and HAM-A scores. However, there was no significant correlation between plasma DβH activity and severity of depressive symptoms in MDD patients. No significant correlation between DβH activities and cognitive assessments neither in BD nor in MDD patients. The present study provides evidence that BD is associated with decreased circulating DβH activity.

    Abstract: Our previous studies documented that interleukin-15 receptor α (IL-15Rα) knockout (KO) mice exhibited hyperactivity, memory impairment, and desperate behavior, which are core features of schizophrenia and depression. Due to the overlapping symptomology and pathogenesis observed for schizophrenia and depression, the present study attempted to determine whether IL-15Rα was associated with the risk of schizophrenia or depression. One hundred fifty-six participants, including 63 schizophrenia patients, 29 depressive patients, and 64 age-matched healthy controls, were enrolled in the study. We investigated the circulating levels of soluble IL-15Rα and analyzed potential links between the IL-15Rα levels and clinical symptoms present in schizophrenia or depressive patients. We observed reduced serum IL-15Rα levels in schizophrenia patients, but not depressive patients compared with controls. Moreover, a significant negative association was observed between the circulating IL-15Rα levels and excited phenotypes in the schizophrenia patients. The IL-15Rα KO mice displayed pronounced pre-pulse inhibition impairment, which was a typical symptom of schizophrenia. Interestingly, the IL-15Rα KO mice exhibited a remarkable elevation in the startle amplitude in the startle reflex test compared to wild type mice. These results demonstrated that serum levels of soluble IL-15Rα were reduced in schizophrenia and highlighted the relationship of IL-15Rα and the excited phenotype in schizophrenia patients and mice.

    Abstract: Schizophrenia is an unexplained, complex and serious mental illness. Blonanserin (BNS) is a new antipsychotic drug widely used in the treatment of schizophrenia. However, large-scale clinical studies have not been conducted in China. A multi-center, prospective, open-label, 12-week surveillance was carried out to evaluate the safety and effectiveness of BNS in patients with schizophrenia in China. Safety assessments included adverse drug reactions (ADRs), extrapyramidal symptoms (EPS), akathisia, concomitant medications for EPS by the end of treatment, and the changes in body weight from baseline by the end of treatment. The effectiveness was evaluated by the Brief Psychiatric Rating Scale (BPRS). From September 2018 to May 2020, of the 1,060 patients enrolled, 1,018 were included in the full analysis set (FAS) and safety set (SS), respectively. ADRs were developed in 205 patients among the included, the incidence being 20.1%. ADRs of EPS occurred in 169 patients, the incidence being 16.6%, ADRs of akathisia occurred in 90 patients, the incidence being 8.8%; concomitant therapeutic and prophylactic agents for EPS accounts for 19.2%; 4.0% of patients had a ≥7% increase in body weight from baseline at 12 weeks after initiating treatment. Using the last-observation-carried-forward (LOCF) method, the changes in total BPRS scores were −11.2 ± 10.17 ( N = 1,018), −16.8 ± 12.69 ( N = 1,018) and −20.6 ± 13.99 ( N = 1,018) after 2/4, 6/8, or 12 weeks, respectively. 53.5% (545/1,018) patients showed response to blonanserin treatment in week 12. The post-marketing surveillance results of BNS demonstrates safety profile and effectiveness of the drug.

    Abstract: It is reported that prepulse inhibition (PPI) deficiency of startle reflex in schizophrenia is associated with positive symptoms and is hereditary. In this study, the perceived spatial separation (PSS) induced-prepulse inhibition paradigm based on the priority effect effectively was used to explore PPI levels of genetically high-risk (GHR) of schizophrenia and clinical high risk (CHR) without family history of psychosis Methods We examined startle magnitude and PPI in38 CHR (No family history of psychosis), 28 GHR (Siblings or children of schizophrenia), and 44 healthy controls (HC). Modified acoustic PPI paradigm included PSS-PPI and perceived spatial co-location PPI (PSC-PPI) with inter-stimulus interval (ISI) of 60 or 120ms. The Structured Interview for Psychosis risk Syndromes (SIPS) and MATRICS Consensus Cognitive Battery (MCCB) was used to measure psychotic symptom and neuropsychological state of individuals Results Using gender, age, and smoking as covariates, Covariance analysis for modified PPI level results revealed that there were significant differences in PSSPPI60 (F = 6.25, p = 0.03) and PSSPI120 (F = 6.57, p = 0.03) paradigm between the three groups. Compared with HC, PSSPPI paradigm detected PPI defects of CHR individuals at 60ms ISI (F = 14.25, p <0.001) and 120ms ISI (F = 14.01, p <0.001). PPI deficiency was not detected in GHR individuals. PPI level in both groups were unrelated to demographics, clinical characteristics, and cognition. Using GLM analysis, the interaction between grouping and experimental paradigm had no significant effect on PPI level at 60ms (F = 1.88, P = 0.16) and 120ms (Z = 1.66, P = 0.19). Discussion It seems that mere heritability of psychosis is not enough to produce PPI defects, which may be related to the progression of psychosis

    Abstract: Many robust studies on prepulse inhibition (PPI) were conducted in patients with schizophrenia, and, increasingly, evidence has indicated individuals who are at clinical high risk for psychosis (CHR). The specificity of the PPI is insufficient with the classic paradigm. The current study investigated an improved perceived spatial separation PPI (PSSPPI) paradigm in CHR individuals, compared with patients of first-episode schizophrenia (FES) and healthy controls (HC), and the relationship between PPI, demographics, clinical characteristics, and cognitive performance. Methods We included 53 FESs, 55 CHR individuals, and 53 HCs. CHRs were rated on the Structured Interview for Prodromal Syndromes (SIPS). The prepulse inhibition measures of perceived spatial co-location PPI (PSCPPI) and PSSPPI paradigms were applied using 60- and 120-ms lead intervals. The MATRICS Consensus Cognitive Battery (MCCB) was used to assess neurocognitive functions. Results Compared with HC, the CHR group had lower PSSPPI level (ISI=60 ms, P & lt;0.001; ISI=120 ms, P & lt;.001). PSSPPI showed a large effect size (ES) between CHR and HC (ISI=60 ms, ES=0.91; ISI=120 ms, ES=0.98); on PSSPPI using 60-ms lead interval, ES ranged from small to large from CHR to FES. PPI deficits in CHR were unrelated to demographics, clinical characteristics, and cognition. Discussion CHR individuals show a sensorimotor gating deficit similar to FES patients on PSSPPI of the startle response, with greater sensitivity than the classic PPI paradigm. PSSPPI appears a promising objective approach for identifying individuals at clinical high risk for psychosis related to a high risk of transition to schizophrenia.

    Abstract: Many robust studies have investigated prepulse inhibition (PPI) in patients with schizophrenia. Recent evidence indicates that PPI may help identify individuals who are at clinical high risk for psychosis (CHR). Selective attention to prepulse stimulus can specifically enhance PPI in healthy subjects; however, this enhancement effect is not observed in patients with schizophrenia. Modified PPI measurement with selective attentional modulation using perceived spatial separation (PSS) condition may be a more robust and sensitive index of PPI impairment in CHR individuals. The current study investigated an improved PSSPPI condition in CHR individuals compared with patients with first-episode schizophrenia (FES) and healthy controls (HC) and evaluated the accuracy of PPI in predicting CHR from HC. We included 53 FESs, 55 CHR individuals, and 53 HCs. CHRs were rated on the Structured Interview for Prodromal Syndromes. The measures of perceived spatial co-location PPI (PSCPPI) and PSSPPI conditions were applied using 60- and 120-ms lead intervals. Compared with HC, the CHR group had lower PSSPPI level (Inter-stimulus interval [ISI] = 60 ms, P & lt; .001; ISI = 120 ms, P & lt; .001). PSSPPI showed an effect size (ES) between CHR and HC (ISI = 60 ms, Cohen’s d = 0.91; ISI = 120 ms, Cohen’s d = 0.98); on PSSPPI using 60-ms lead interval, ES grade increased from CHR to FES. The area under the receiver operating characteristic curve for PSSPPI was greater than that for PSCPPI. CHR individuals showed a PSSPPI deficit similar to FES, with greater ES and sensitivity. PSSPPI appears a promising objective approach for preliminary identification of CHR individuals.
