The protective effect of physical activity on mental health of middle school students at different stages during the COVID-19 outbreak.

This study aims to further understand the changes in physical activity level(PAL) and mental health among adolescents before and after the outbreak of COVID-19 and explore the protective role of physical activity (PA) on the mental health of adolescents during major disasters. A convenient sampling method was used to conduct a cross-sectional survey. The cross-sectional data from 2838 Chinese middle school students (mean age = 14.91 ± 1.71 years, 49.54% female) were used, of which 1,471 and 1,367 were in 2021 and 2022, respectively. The PAL was collected using the Physical Activity Questionnaire for Children (PAQ-CN), mental health status was collected using the Mental Health Inventory of Middle School Students (MMHI-60), sociodemographic information was collected using a self-reported questionnaire. Before and after the outbreak of COVID-19, the PAL of adolescents was 2.36 ± 0.74 and 2.50 ± 0.66, respectively, with a significant difference (p < 0.01, 95% CI: 0.09, 0.19). The mental health scores were 1.71 ± 0.60 and 1.86 ± 0.73, respectively, with a significant difference (p < 0.01, 95% CI: - 0.20, - 0.10). The detection rates of mental health problems were 27.50% and 35.50%, respectively. The rates of achieving PAL standards were 30.20% and 18.00% among adolescents, while the rates of not achieving PAL standards were 39.60% and 18.00%. PA is a protective factor for the mental health of adolescents during major disasters.

The Ending Effect in the Domain of Gambling: The Effect of Gain-Loss Status on Economic Decision-Making.

Previous studies have shown that people prefer risk-taking at the end of gambles, a phenomenon called the ending effect. By using the Guess Gambling Game, we investigated the impact of gain-loss status on the ending effect (Experiment 1) and whether and how this effect may be affected by time reference (Experiment 2) and gender (Experiment 1&2). In Experiment 1, we observed the ending effect only in the gain group. Furthermore, gender differences exist in the loss group behavior, females were more risk-averse than males, and males tend to investment more initially and then reduce their investment in a U-shaped pattern (Experiment 1&2). Next, in Experiment 2, the findings indicated that participants in the gain group made riskier decisions and were willing to allocate more money for additional decision opportunities, irrespective of the time conditions. Additionally, under time-limited condition, participants tended to make more decisions in the final round, aiming to maximize their choices times within the limited time. These results contribute to a better understanding of the boundary conditions surrounding the ending effect in risky decision-making and may offer a scientific basis for mitigating and intervening in irrational decision-making.

Nonbonding Electron Delocalization Stabilizes the Flexible N8 Molecular Assembly.

Electron delocalization has an important impact on the physical properties of condensed materials. However, the L-electron delocalization in inorganic, especially nitrogen, compounds needs exploitation to improve the energy efficiency, safety, and environmental sustainability of high-energy-density materials (HEDMs). This Letter presents an intriguing N8 molecule, ingeniously utilizing nitrogen's L-electron delocalization. The molecule, exhibiting a unique lollipop-shaped conformation, can fold at various angles with very low energy barriers, self-assembling into environmentally stable, all-nitrogen crystals. These crystals demonstrate unparalleled stability, high energy density, low mechanical sensitivity, and optimal electronic thermal conductivity, outperforming existing HEDMs. The remarkable properties of these designed materials are attributed to two distinct delocalized systems within nitrogen's L-shell: π- and lone pair σ-electrons, which not only stabilize the molecular structure but also facilitate interconnected 3D networks of intermolecular nonbonding interactions. This work might pave the way to the experimental synthesis of environmentally stable all-nitrogen solids.

Parental self-control facilitates adolescent psychological adjustment sequentially through parents' perceived stress/mindful parenting and adolescent self-control.

Adolescence is a unique developmental period marked with significant changes and challenges. As such, maintaining optimal psychological adjustment is crucial for young people, especially during the COVID-19 pandemic when their adjustment became more challenging. Self-control is a vital ability assisting individuals to navigate difficulties and stay well-adjusted during turbulent times. While the associations between adolescent self-control and adjustment have been well-documented, parental self-control has been considered to play a more fundamental role in adolescent adjustment. However, this consideration has received scant research. Drawing on the intergenerational transmission model of self-regulation, we examined an understudied yet plausible idea that parental self-control facilitates adolescent adjustment through parents' lower levels of perceived stress/better mindful parenting and adolescents' improved self-control. A two-wave survey study, spanning 1 year apart, was conducted among 426 Chinese adolescents (Mage = 11.6 years, 53.5% boys) and their parents. Parents rated their self-control, perceived stress, and mindful parenting at T1, while adolescents rated their self-control and adjustment (i.e., psychological difficulties and life satisfaction) at T1 and T2. The results of chain mediation model showed that after controlling for demographic covariates and baseline levels of adolescent self-control and adjustment, T1 paternal self-control facilitated T2 adolescent adjustment through fathers' lower levels of perceived stress and adolescents' improved self-control. By contrast, T1 maternal self-control facilitated T2 adolescent adjustment through mothers' better mindful parenting and adolescents' improved self-control. These findings advance our understanding of how self-control is transmitted from parents to offspring and clarify the processes of how parental self-control facilitates adolescent adjustment.

Construction of a model for adolescent physical and mental health promotion based on the multiple mediating effects of general self-efficacy and sleep duration.

We developed a model for promoting adolescent physical and mental health (MH) to investigate the integrated pathways of physical activity (PA), MH, general self-efficacy (GSE), and sleep duration (SD) promotion among adolescents in China. The research hypotheses were tested using questionnaires, descriptive statistics, and validated factor analysis. The mean age of the respondents was 14.94 ± 1.76 years, the PA level was 2.49 [95% confidence interval (CI): 2.46-2.53], the GSE score was 2.60 (95% CI: 2.57-2.64), the SD was 436.52 min/day (95% CI: 432.89-440.15), and the total mean MH score was 1.72 (95% CI: 1.69-1.76) (model fitness index: χ2/df = 1.295, comparative fit index = 0.999, Tucker-Lewis index = 0.997, root mean square error of approximation = 0.014, standardized root mean square residual = 0.007). The SD accounted for 46.85% of the mediating effect. The adolescents exhibited moderately low PA levels, severe SD deficits, and high rates of overall MH abnormalities. Consequently, the constructed model for promoting adolescent physical health and MH was confirmed to be reliable; GSE and SD are significant factors mediating MH promotion.

Preparation of High Water-Soluble Trichoderma Co-Culture Metabolite Powder and Its Effects on Seedling Emergence Rate and Growth of Crops.

Trichoderma spp. are widely used beneficial microbes in agricultural production; however, the improper carrier choice for Trichoderma agent preparation can alter the effectiveness of Trichoderma fungicides. In this study, the co-culture of four Trichoderma strains produced a large amount of free amino acids, with a content of 392.8414 ug/mL, and significantly improved the production level of γ-aminobutyric acid. A greenhouse experiment further showed that the co-culture of Trichoderma synergistically improved the female flower development and bacterial angular leaf spot resistance. The effects of ten kinds of carriers were compared in terms of water absorption and heat generation, as well as their effects on the seedling emergence rate and the plant growth promotion of maize, cucumber, and pakchoi cabbage. Each carrier was screened to mix with four strains of co-culture metabolites to prepare highly soluble and quality powders. The results showed that there were different effects of the carriers themselves and Trichoderma strain co-culture metabolite powder prepared with the carriers on seedling emergence rate and seedling growth. Β-cyclodextrin performed best in high solubility and low heat generation upon absorbing water and in easy drying in processing operations. Trichoderma strains co-culture metabolite powder with ß-cyclodextrin as a carrier provided the most obvious promotion effects on seedling emergence rate and seedling growth. Therefore, ß-cyclodextrin was determined to be an ideal carrier to prepare a highly water-soluble Trichoderma agent. Taken together, the study successfully developed a new type of highly soluble powder containing Trichoderma co-culture metabolites that is expected to benefit farming drip irrigation and spraying systems for the promotion of crop growth and disease control.

Hemolysis dictates monocyte differentiation via two distinct pathways in sickle cell disease vaso-occlusion.

Sickle cell disease (SCD) is a hereditary hemoglobinopathy characterized by painful vaso-occlusive crises (VOC) and chronic hemolysis. The mononuclear phagocyte system is pivotal to SCD pathophysiology, but the mechanisms governing monocyte/macrophage differentiation remain unknown. This study examined the influence of hemolysis on circulating monocyte trajectories in SCD. We discovered that hemolysis stimulated CSF-1 production, partly by endothelial cells via Nrf2, promoting classical monocyte (CMo) differentiation into blood patrolling monocytes (PMo) in SCD mice. However, hemolysis also upregulated CCL-2 through IFN-I, inducing CMo transmigration and differentiation into tissue monocyte-derived macrophages. Blocking CMo transmigration by anti-P selectin antibody in SCD mice increased circulating PMo, corroborating that CMo-to-tissue macrophage differentiation occurs at the expense of CMo-to-blood PMo differentiation. We observed a positive correlation between plasma CSF-1/CCL-2 ratios and blood PMo levels in patients with SCD, underscoring the clinical significance of these two opposing factors in monocyte differentiation. Combined treatment with CSF-1 and anti-P selectin antibody more effectively increased PMo numbers and reduced stasis compared with single-agent therapies in SCD mice. Altogether, these data indicate that monocyte fates are regulated by the balance between two heme pathways, Nrf2/CSF-1 and IFN-I/CCL-2, and suggest that the CSF-1/CCL-2 ratio may present a diagnostic and therapeutic target in SCD.

Changes in physical activity level of adolescents and its relationship with mental health during regular COVID-19 prevention and control.

PURPOSE: This study aimed to analyze the impact of regular prevention and control of COVID-19 on the physical activity level (PAL) of adolescents and the relationship between PAL and mental health. METHODS: Using the convenience sampling method, two stages of the on-site cross-sectional investigation were conducted in 11 middle schools in Guiyang City in China. There were 1132 participants who completed the Physical Activity Questionnaire for old children (PAQ-C) in October 2020, and 1503 participants who completed the PAQ-C and Mental Health Inventory of Middle-school students (MMHI-60) in October 2021. All participants reported their demographic data. Descriptive, quantitative statistics were used for data analysis. One-way ANOVA was used to explore associations between PAL and mental health. RESULTS: The results of statistical analysis showed a gradual yearly increase in the PAL of teenagers, and the PAL of male junior middle school students has a significant increase (p < .05); while that of adolescents in Grade 10 significantly decreased (p < .001). There is a statistically significant correlation between adolescents' mental health (except for anxiety) and PAL (p < .05). The overall abnormal rate of mental health was 27.9%; The PAL and the total mean score of mental health had a negative correlation (p < .001). There was a significant difference between mental health scores and corresponding PAL (p < .001). Furthermore, there are statistically significant differences in scores of mental health factors corresponding to varying PAL among junior high school students and male students (p < .05). CONCLUSIONS: The regular epidemic prevention and control measures had significant adverse effects on the PAL of girls and high school adolescents, especially Grade 10 adolescents. Improving adolescents' PAL can promote their mental health. Interventions based on PAL slightly lower than the level recommended in the physical activity guidelines can bring significant mental health effects.

Longitudinal association between interparental conflict and risk-taking behavior among Chinese adolescents: testing a moderated mediation model.

BACKGROUND: The interparental conflict has been associated with an increased adolescents' engagement in risk-taking behaviors. However, few studies have examined the potential mediation of deviant peer affiliation and the potential moderation of school climate. Grounded in the ecological system theory, this study aimed to explore the mediating role of deviant peer affiliation and the moderating role of school climate between the association of interparental conflict and risk-taking behavior. METHODS: This study conducted a longitudinal design (3 time points, 3 months apart) with the sample comprising 550 middle school students in southeastern China (52.91% males; mean age at Time 1 = 15.37). The performed measurements encompassed interparental conflict (T1), deviant peer affiliation (T2), school climate (T3), risk-taking behavior (T1/T2/T3), and demographic information. RESULTS: The moderated mediation model revealed that after controlling for T1/T2 risk-taking behavior, T1 interparental conflict was longitudinally and positively correlated with T3 risk-taking behavior through T2 deviant peer affiliation. Furthermore, moderated mediation analysis demonstrated that a positive school climate ameliorated the adverse impact of deviant peer affiliation on risk-taking behavior, thereby mitigating the indirect effect of interparental conflict on risk-taking behavior among adolescents. CONCLUSIONS: Our findings propose a nuanced explanation of the processing mechanisms between interparental conflict and risk-taking behaviors among Chinese adolescents. The theoretical and practical implications of the findings are discussed.

High-efficiency adsorption removal of CR and MG dyes using AlOOH fibers embedded with porous CoFe2O4 nanoparticles.

Owing to the toxicity and difficulty in degradation, how to the effective separation for the residual dyes in the aqueous solution is still an issue with great challenge in the area of environmental protection. Now, to high-efficiency removal of organic dyes from the aqueous solution, we design a unique AlOOH/CoFe2O4 adsorbent with porous CoFe2O4 nanoparticles embedded on the AlOOH fibers using a simple hydrothermal technique and calcination process. The structural properties and surface characteristics of the AlOOH/CoFe2O4 composites are detailedly analyzed by XRD, FTIR, XPS, TEM and SEM. Here, the high SBET and specific porous structure are beneficial to improve the adsorption performance of AlOOH/CoFe2O4 adsorbents. Especially, when the molar ratio of AlOOH to CoFe2O4 in the AlOOH/CoFe2O4 fibers is 1:1, an optimal performance on adsorbing anionic Congo red (CR) and cationic methyl green (MG) dyes can be obtained at pH = 6.29, where the corresponding maximum adsorption capacities reach up to 565.0 and 423.7 mg g-1, respectively. Factors leading to the change in the ability of adsorbing CR and MG dyes are systematically discussed, including contact time, temperature, initial concentrations, and pH values of the solutions. Meanwhile, the uptake of CR and MG dyes can best conform to Langmuir isotherm model and pseudo-second-order adsorption kinetics. The thermodynamic analysis verifies that the dye adsorption process is spontaneous and endothermic. Moreover, from the point view of practical application, the good reusability further makes the as-synthesized magnetic AlOOH/CoFe2O4 composite be a perfect adsorbent with efficiently removing both anionic and cationic dyes from aqueous solutions.

The Association between Peer Victimization and Risk-Taking Behavior among Chinese Adolescents: Testing a Moderated Mediation Model.

Peer victimization has been considered a main source of risk-taking behavior among adolescents, but little is known about the mechanisms underlying this association. Based on the social-cognitive theory and the person-environment interactions model, the current study built a moderated mediation model to explore whether self-control mediated the link between peer victimization and adolescent risk-taking behavior and whether positive parenting moderated this link. We used a 2-time longitudinal design (6 months apart) to investigate 488 adolescents (Mage = 15.63 years, SD = 1.64) from 3 middle schools in Guangzhou. The results were as follows: (1) There were significant correlations among peer victimization, adolescent risk-taking behavior, self-control, and positive parenting when controlling for demographic variables. (2) Peer victimization not only influenced risk-taking behavior directly, but also indirectly through self-control. (3) Positive parenting moderated the influence of self-control on risk-taking behavior. In other words, positive parenting could enhance the inhibitory effect of self-control on risk-taking behavior. The results help reveal the mechanism by which adolescent risk-taking behavior forms and may help inform interventions against adolescent risk-taking behavior.

Longitudinal association between parental involvement and internet gaming disorder among Chinese adolescents: Consideration of future consequences as a mediator and peer victimization as a moderator.

Background and aims: Internet gaming disorder (IGD) in adolescents is a concerning issue. Positive parenting has been found to protect against adolescent IGD, but the underlying mechanisms await further investigation. As such, this study examined the longitudinal association between parental involvement (PI) - a specific type of positive parenting understudied in the literature of adolescent gaming disorder - and IGD. Moreover, this study also tested consideration of future consequences (CFC) as a mediator and peer victimization (PV) as a moderator. Methods: A two-wave longitudinal research spanning 6 months apart was conducted. Participants were Chinese adolescents (final N = 434; 222 females; Mage = 14.44 years, SD = 1.56). They provided ratings on PI, PV, and IGD at Wave 1, and CFC-immediate, CFC-future, and IGD at Wave 2. Results: Descriptive statistics showed that the prevalence rate of IGD was 10.81% and 9.45% at Waves 1 and 2, respectively. Moreover, results of moderated mediation model found that after controlling for Wave 1 IGD and covariates, Wave 1 PI was associated with Wave 2 IGD via preventing adolescents who had higher levels of PV from developing a tendence of CFC-immediate and via promoting adolescents who had lower levels of PV to develop a tendence of CFC-future. Discussion and Conclusions: Altogether, these results suggest that facilitative ecological systems (e.g., positive parenting and good relationships with peers) and personal strengths (e.g., positive future orientation) jointly contribute to the mitigation of adolescent IGD.

Linking Self-Control to Negative Risk-Taking Behavior among Chinese Late Adolescents: A Moderated Mediation Model.

Negative risk-taking behaviors refer to voluntary behaviors that lead to more harm than good. Low self-control is a crucial predictor of adolescents' negative risk-taking behavior, but its internal mechanisms require further exploration. To reveal the working process underlying the association between self-control and adolescents' negative risk-taking behaviors, we investigated the mediation of regulatory focus and the moderation of sense of power. A total of 2018 students (37.6% males) from two universities in Guangzhou, China, participated in a survey that investigated their self-control, negative risk-taking behavior, regulatory focus and sense of power. The results revealed that after controlling for the adolescents' sex and their parents' educational level, prevention focus partially mediated the association between self-control and negative risk-taking behavior. Moreover, sense of power moderated the association between self-control and prevention focus. Furthermore, the association between self-control and negative risk-taking behavior through prevention focus was stronger among adolescents with a high sense of power than among those with a low sense of power. Therefore, our findings suggest that regulatory focus and sense of power might be the mechanisms that explain how self-control is related to negative risk-taking behavior. These results thus provide a foundation for the prevention of and intervention in adolescents' negative risk-taking behavior.

The Interpretation of the Role of a Polyketide Synthase ClPKS18 in the Pathogenicity of Curvularia lunata.

Plant pathogenic fungus Curvularia lunata (Wakker) Boedijn causes leaf spot diseases in several plants such as Oryza sativa, Sorghum bicolor (L.) Moench, and Capsicum frutescens. It has been spread worldwide, specifically in maize-growing regions. The polyketide synthase (PKS) plays a significant role in secondary metabolite production and its effect on virulence. The Clpks18 of C. lunata strongly correlated with its pathogenicity. The role of Clpks18 gene on the pathogenic activity of C. lunata remains unclear. Hence, in this study, we analyzed the importance of Clpks18 gene on the hyphae and conidial melanization and on the sporulation and hyphal growth. The deletion of Clpks18 gene reduced the production of methyl 5-(hydroxymethyl)furan-2-carboxylate toxin. The virulence of ΔClpks18 mutant was significantly reduced compared with the wild type. The metabolomics data revealed that (R)-(-)-mellein was a vital factor in the virulence of C. lunata. The (R)-(-)-mellein and the toxin produced by C. lunata were detected in the maize leaves during its infestation. In addition, the metabolomic analysis showed that the Clpks18 gene influences glycerolipid, non-ribosomal peptide biosynthesis, and its metabolism. This study demonstrates that the Clpks18 gene is important for the pathogenicity of C. lunata by influencing the complex metabolic network.

Theory of planned behavior explains males' and females' intention to receive COVID-19 vaccines differently.

Uptake of COVID-19 vaccines is an important measure to curb the transmission of the coronavirus. Before the vaccines were available, numerous studies found that people had a moderate-to-high intention to receive the vaccines. Several studies have also used the theory of planned behavior (TPB) to predict people's COVID-19 vaccination intention with three elements (i.e. attitudes, subjective norms, and perceived behavioral control) . However, the vaccination rate falters after the vaccines became available, and there were few updated data documenting people's vaccination intention and how well TPB can explain their intention. In addition, studies investigating other outcomes found that the predictive utilities of TPB often varied across gender, but such gender differences received little consideration in the literature of COVID-19 vaccination intention. To help fill these gaps, we examined the associations between TPB elements and people's intention to receive COVID-19 vaccines and the moderation of gender in the context of vaccination campaign. Participants were 405 Chinese citizens. They reported on the three TPB elements and intention to receive vaccines in the coming months. Descriptive results showed that participants' vaccination intention was moderate. Results of path analysis showed that subjective norms and perceived behavioral control were positively related to vaccination intention for the whole sample. Furthermore, results of multigroup path analysis showed that attitudes were only related to males', while subjective norms were only related to females', intention. These findings enhance the utility of TPB in explaining people's COVID-19 vaccination intention and inform gender-specific strategies to boost males' and females' vaccination intention.

Longitudinal association between poor parental supervision and risk-taking behavior: The role of self-control and school climate.

INTRODUCTION: Although poor parental supervision has been associated with an increased adolescents' propensity for risk-taking behavior, few researchers have investigated nuanced mechanisms of how and for whom from the perspective of "family × school." Inspired by ecological system theory and self-control theory, this study aimed to investigate the mediating role of self-control and the moderating role of school climate between the link between poor parental supervision and risk-taking behavior. METHODS: Four hundred and ninety-one Chinese adolescents (231 females, Mage = 15.39 ± 1.36) were recruited to participate in a three-wave longitudinal study (3 months apart) and complete questionnaires regarding poor parental supervision (W1), school climate (W1), self-control (W2), and risk-taking behavior (W1/W3). RESULTS: After controlling for W1 risk-taking behavior, our moderated mediation model indicated that W1 poor parental supervision was positively related to W3 risk-taking behavior by restraining the development of W2 self-control. Additionally, a high level of school climate as a protective factor buffered the negative impact of poor parental supervision on adolescents' self-control, further reducing risk-taking behavior. CONCLUSION: Our findings shed light on the processing mechanisms between poor parental supervision and risk-taking behavior among Chinese adolescents and underscore the importance of effective preventions and interventions to facilitate adolescents' healthy development.

Profiles of positive changes in life outcomes over the COVID-19 pandemic in Chinese adolescents: the role of resilience and mental health consequence.

BACKGROUND: The 2019 coronavirus (COVID-19) has caused enormous negative impacts on adolescents' routines, social interaction, interpersonal relationships, psychosocial well-being, and physical health. Nevertheless, theories suggest that individuals also often seek out solutions that may facilitate positive changes when they are faced with uncertainty and crisis. However, the existing literature has disproportionately focused on the negative effect of COVID-19 on adolescents, and scant research has examined to what extent and in what aspects adolescents would experience positive changes in times of the pandemic. This pre-registered research aims to bridge said gaps by: (1) exploring different profiles of positive changes in various life outcomes in Chinese adolescents over the COVID-19 pandemic; (2) examining the role of resilience in differentiating different profiles; (3) comparing adolescents' mental health across profiles. METHOD: Participants were 2,567 adolescents aged 12 to 24 recruited from 32 provinces in mainland China (66.89% females; Mage = 19.87 years, SD = 2.02). Through an online survey, participants rated how much their lives of different domains had experienced positive changes since the outbreak of the pandemic. They also answered standardized questionnaires that measured their resilience and mental health. RESULTS: Results of latent profile analysis revealed three profiles: limited positive changes (33.3%), partial positive changes (49.5%), and overall strong positive changes (17.2%). Moreover, adolescents with a higher level of resilience were more likely to be categorized into the partial positive changes profile compared to the limited positive changes profile and categorized into the overall strong positive changes profile compared to the other two profiles, after controlling for multiple covariates. Adolescents in the overall strong positive changes profile had better mental health than their counterparts of the other two profiles. CONCLUSION: Chinese adolescents appear to experience positive changes in various life outcomes during the COVID-19 pandemic, especially for those with high levels of resilience. Such positive changes have important implications on adolescents' mental health.

Pharmacological treatments for psychotic symptoms in dementia: A systematic review with pairwise and network meta-analysis.

Psychotic symptoms of dementia are highly prevalent and lead to poor medical outcomes and substantial dysfunction. To date, which drug to use remains controversial without a summary of all direct or indirect comparisons of pharmacotherapy. Therefore, we conducted a systematic review with pairwise and network meta-analysis to examine efficacy and tolerability outcomes of pharmacological treatments in dementia patients. MEDLINE, Cochrane Library, EMBASE, and PubMed were searched systematically up to August 31, 2020. We included trials of cholinesterase inhibitors (ChEIs), memantine, antipsychotics, antidepressants, and mood stabilizers, with final approval from the U.S. Food and Drug Administration. We ranked the comparative effects of all drugs against placebo with surface under the cumulative ranking (SUCRA) probabilities. This analysis is based on 34 trials, which included 10,415 patients randomly assigned to 15 commonly used drug regimens. Donepezil (standardized mean difference [SMD] -0.30, 95% credible interval [CrI] -0.50 to -0.12; SUCRA, 0.85), memantine (SMD -0.20, 95%CrI -0.34 to -0.07; SUCRA, 0.68) and aripiprazole (SMD -0.17, 95% CrI -0.32 to -0.02; SUCRA, 0.62) showed greater benefit than placebo, and with relatively good tolerability in network meta-analyses. Risperidone was also found to be more efficacious than placebo (SMD -0.16, 95% CrI -0.28 to -0.05; SUCRA, 0.60), but with poor tolerability (odds ratios [OR] 1.50, 95% CrI 1.06-2.26). Donepezil, memantine, haloperidol, aripiprazole and risperidone were more efficacious than quetiapine (SMDs ranged from -0.36 to -0.22). Besides, donepezil, memantine and mirtazapine were more efficacious than sertraline (SMDs ranged from -0.47 to -0.36). Most of the results were rated as "low" to "very low". Several effective treatment choices for psychotic symptoms are available across drug classes. Donepezil, memantine and aripiprazole are probably the appropriate options to consider when a pharmacological treatment is indicated. Given the limitations of the meta-analytic approach and the low methodological quality of the majority of studies, our results should be cautiously interpreted.

Chinese public's panic buying at the beginning of COVID-19 outbreak: The contribution of perceived risk, social media use, and connection with close others.

Panic buying is a globally witnessed behavior during the outbreak of COVID-19. This consumer behavior is related to many undesirable consequences, ranging from disrupting economic stability to hindering timely provision of supplies to those in dire need. As such, to understand the causes and underlying mechanisms of panic buying is crucial. Based on terror management theory, this study examined the contribution of perceived risk, social media use, and connection with close others to panic buying. Data were collected through an online survey from 972 Chinese citizens (65.9% female, M age = 33.69 years) at the beginning period of COVID-19 in early February 2020. The results found that individuals with a higher level of perceived risk were more prone to engage in panic buying, but this link was mitigated by connection with close others when individuals less used social media. Theoretically, this study advances the understandings of the psychological processes of panic buying during health crisis. Practically, alleviating individuals' perceived risk, establishing a healthy habit of social media use, and strengthening social ties are important to circumventing panic buying in times of COVID-19.

3D porous coral-like Co1.29Ni1.71O4 microspheres embedded into reduced graphene oxide aerogels with lightweight and broadband microwave absorption.

In this work, three-dimensional (3D) porous coral-like Co1.29Ni1.71O4 microspheres were successfully combined with reduced graphene oxide (rGO) to form Co1.29Ni1.71O4/rGO aerogels as an efficient microwave absorber by a facile calcination and hydrothermal method. The elemental composition, microstructure, and morphology of the as-synthesized composites were characterized, and the electromagnetic wave absorption performance were analyzed in the frequency range of 2.0-18.0 GHz. The results show that adjusting the mass ratio of Co1.29Ni1.71O4 microspheres and rGO in the composites can effectively tune the electromagnetic parameters, which in turn improves their microwave absorption performance. Here, the minimum reflection loss (RLmin) of the Co1.29Ni1.71O4/rGO aerogels is -51.76 dB with an effective absorption bandwidth (RL < -10 dB) of 7.04 GHz (10.96-18 GHZ) at the thickness of 2.66 mm and a low filling ratio of 15 wt%. It can be demonstrated that the superior microwave absorption performance is attributed to the synergistic effect of impedance matching and dielectric loss, the unique 3D porous structure as well as the abundant interface of the composites. In brief, this study provides a new strategy for the design of magnetic/dielectric high-performance microwave absorbing materials.
