Future-oriented temporal perspective promotes wise reasoning.

OBJECTIVE: Across three experiments (N = 622), we investigated the effect of the future temporal perspective on wise reasoning within the context of interpersonal conflicts. METHOD: Studies 1 and 2 applied two heterogeneous measurements of wise reasoning: self-report and open-ended measurements. Participants reasoned about their recent interpersonal conflicts from a future (i.e., 1 year from now) or a present perspective. Similarly, Study 3 tested the relationship between various future temporal distances (i.e., 1 week, 1 year, 10 years, 30 years from now) and wise reasoning. RESULTS: The future temporal perspective significantly promoted wise reasoning compared to the present perspective, especially when the focus was 30 years in the future. Moreover, reasoning about a conflict event from a future perspective first might cause a carry-over effect on reasoning from the present perspective later. CONCLUSION: Future-oriented temporal perspective significantly improves wise reasoning.

Separation of m-cresol and p-cresol by NaZSM-5 with different Si/Al ratios.

m-Cresol and p-cresol are widely used in medicine and pesticides as important chemical intermediates. They are generally produced as a mixture in industry and are difficult to separate due to the similarities in both chemical structures and physical properties. The adsorption behaviours of m-cresol and p-cresol on zeolites (NaZSM-5 and HZSM-5) with different Si/Al ratios have been compared by static experiments. Selectivity on NaZSM-5(Si/Al = 80) could be greater than 6.0. Adsorption kinetics and isotherms were investigated in detail. The kinetic data was correlated by PFO, PSO, and ID models, the NRMSE of which were 14.03%, 9.41%, and 21.11%, respectively. In the meanwhile, according to the NRMSE of Langmuir (6.01%), Freundlich (57.80%), D-R (1.1%), and Temkin (0.56%) isotherms, adsorption on NaZSM-5(Si/Al = 80) was mainly a monolayer and chemical adsorption process. It was endothermic for m-cresol and exothermic for p-cresol. The Gibbs free energy, entropy, and enthalpy were calculated accordingly. The adsorption of cresol isomers on NaZSM-5(Si/Al = 80) were both spontaneous, and it was exothermic (ΔH = -37.11kJ/mol) for p-cresol while endothermic (ΔH = 52.30kJ/mol) for m-cresol. Additionally, ΔS were respectively -0.05 and 0.20 kJ·mol-1·K-1for p-cresol and m-cresol, which were both close to zero. The adsorption was mainly driven by enthalpy. The result of breakthrough further demonstrated m-cresol and p-cresol could be separated effectively by NaZSM-5(Si/Al = 80). Additionally, the selectivity increased from 7.53 to 14.72 after four cycles regeneration with 9.95% and 53.96% decreases in the adsorption amounts for m-cresol and p-cresol, respectively. In conclusion, NaZSM-5(Si/Al = 80) could be a feasible adsorbent for the separation of m-cresol and p-cresol.

Judging a book by its cover: Cultural differences in inference of the inner state based on the outward appearance.

The world can be represented by two layers of information: How it appears on the outside (outward appearance) and what it is on the inside (inner state). To what extent an outward appearance is assumed to reflect the inner state is fundamental to social inference and judgments. Conceptualizing inference in terms of the relationship between the outward appearance and the inner state generates an integrative interpretation for a wide range of phenomena. We showed that Chinese were more likely than Euro-Canadians to make inference of inner state that deviated from outward appearance, whereas Euro-Canadians were more likely than Chinese to infer a convergence between outward appearance and inner state (Studies 1-5). We observed these cross-cultural patterns in various contexts involving people or physical structures. Individual differences in correspondence bias or response bias did not explain these patterns. The lay belief that outward appearance can be misleading mediated the cultural effects (Study 4). To probe the underlying process, two additional experiments showed that highlighting the misleading nature of appearance, but not highlighting the power of the situation, reduced Americans' beliefs (Study 6) and inference (Study 7) that the outward appearance reflects the inner state. By focusing on the assumed relationship between the outward appearance and inner state, these findings provide a unique angle for understanding cross-cultural phenomena and have practical implications in daily life.

The Impact of Culture and Social Distance on Humor Appreciation, Sharing, and Production.

Building on the benign violation theory and self-construal theory, we conducted four studies to examine how culture and social distance would influence humor appreciation, sharing, and production. Study 1 found that Chinese participants appreciated and intended to share a joke involving distant others more than that involving close others. They also generated funnier titles for a joke involving distant others than close others. Studies 2a and 2b compared Chinese and Americans using various types of jokes, replicating the social distance effect among Chinese but finding little effect of social distance among Americans. In Study 3, interdependence-primed participants generated more humorous titles for a joke involving distant than close others, whereas independence-primed participants showed no effect of social distance. The research provides further support to the benign violation theory from a cultural perspective and has important implications for cross-cultural communications.

Preparation and characterization of a self-crosslinking sodium alginate-bioactive glass sponge.

In this research, bioactive glass particles prepared by the reactive flash nanoprecipitation method (RFNP-BG particles) are used to crosslink sodium alginate to prepare biological sponges (SA-BG sponges) by freeze-drying. An experiment for the cross-linking mechanism confirms that the continuous release of Ca2+ from RFNP-BG is promoted by the crosslinking reaction and in turn leads to the gelation process of SA. Bioactive glass particles not only provide Ca2+ for the crosslinking of sodium alginate, but also enhance the mechanical properties of the SA-BG sponges. The results show that the elastic modulus of the SA-BG sponges increases from 0.026 MPa to 0.641 MPa, and the resistance to external force deformation is greatly improved; the thermal decomposition temperature increases from 105°C to 166°C; compared with a pure SA sponge, the water resistance is significantly improved. In vitro cell experiments show that the SA-BG sponges have a certain adverse effect on cell proliferation, but it is in an acceptable range. qPCR results show that the SA-BG sponges have a certain beneficial effect on promoting osteogenic gene expression. The SA-BG sponges have great application potential in the fields of medicine, hemostasis, and wound closure.

Schisandrin B protects against LPS-induced inflammatory lung injury by targeting MyD88.

BACKGROUND: Acute lung injury (ALI) is a challenging clinical syndrome that manifests as an acute inflammatory response. Schisandrin B (Sch B), a bioactive lignan from Schisandra genus plants, has been shown to suppress inflammatory responses and oxidative stress. However, the underlying molecular mechanisms have remained elusive. HYPOTHESIS/PURPOSE: This study performed an in-depth investigation of the anti-inflammatory mechanism of Sch B in macrophages and in an animal model of ALI. METHODS: qPCR array was used to probe the differential effects and potential target of Sch B. ALI was induced by intratracheal administration of LPS in experimental mice with or without Sch B treatment. RESULTS: Our studies show that Sch B differentially modulates inflammatory factor induction by LPS in macrophages by directly binding myeloid differentiation response factor-88 (MyD88), an essential adaptor protein in the toll-like receptor-4 (TLR4) pathway. Sch B spares non-MyD88-pathways downstream of TLR4. Such inhibition suppressed key signaling mediators such as TAK1, MAPKs, and NF-κB, and pro-inflammatory factor induction. Pull down assay using biotinylated-Sch B validate the direct interaction between Sch B and MyD88 in macrophages. Treatment of mice with Sch B prior to LPS challenge reduced inflammatory cell infiltration in lungs, induction of MyD88-pathway signaling proteins, and prevented inflammatory cytokine induction. CONCLUSION: In summary, our studies have identified MyD88 as a direct target of Sch B for its anti-inflammatory activity, and suggest that Sch B may have therapeutic value for acute lung injury and other MyD88-dependent inflammatory diseases.

Religiosity and the Naturalness Bias in Drug and Vaccine Choices.

Research reveals a bias for natural versus synthetic drugs. We sought to determine if this bias is associated with religiosity. Three cross-sectional studies (N = 1399 U.S. participants) were conducted to examine the impact of religiosity on the naturalness bias in the drug and vaccine domains. We assessed measures of religiosity, preferences for natural versus synthetic drugs and vaccines in hypothetical scenarios, and a health-related behavior (COVID-19 vaccination status). The results revealed that participants high versus low in religiosity had stronger preferences for natural versus synthetic drugs and vaccines. Furthermore, participants high versus low in religiosity were less likely to have taken the COVID-19 vaccine, and the natural drug bias was a mediator of this effect. Overall, participants higher in religiosity had a stronger preference for natural versus synthetic drugs and vaccines, and this preference had implications for health behavior.

The Naturalness Bias Influences Drug and Vaccine Decisions across Cultures.

HIGHLIGHTS: The naturalness bias - preferring natural to synthetic drugs or vaccines - occurred across cultures (Americans, Canadians, and Chinese).Chinese participants showed a stronger naturalness bias than Americans did when the medical context was focused on vaccination, and safety concerns mediated this effect.The naturalness bias may influence medical decision making across cultures, but Chinese participants may be more sensitive to naturalness in a vaccine context.

Amino acid profiles in the tissue and serum of patients with liver cancer.

Most patients with liver cancer were found late and lost the chance of surgery. Liquid biopsy can monitor the risk of tumor recurrence and metastasis, quickly evaluate the curative effect of tumor treatment, and is conducive to early screening and auxiliary diagnosis of high-risk groups. Amino acid (AA) profiling has been used to the diagnosis and the prognosis for cancers. However, little was known about the profiles of AA of liver cancer. In this study, we used tRNA in Cancer database to analyze the AA levels in liver cancer tissues. Blood samples of patients with liver cancer were collected and analyzed using the automatic AA analyzer. We found that valine, isoleucine, and leucine were decreased significantly both in the plasma and the tumor tissues of patients with liver cancer. However, upregulation of methionine was observed in tissues and plasma of patients with liver cancer. Interestingly, tyrosine, and phenylalanine were decreased in tumor tissue but increased in the plasma of patients with liver cancer. This is the first report provided an overview of AA profile in both plasma and tissue for patients with liver cancer. AA levels can be used as diagnostic and prognostic markers of patients with liver cancer.

Culture, Aging, Self-Continuity, and Life Satisfaction.

The present work examines how culture and age interact to influence self-continuity and life satisfaction. Specifically, we compared Canadian and Chinese young (17-26 years old) and older adults (60-88 years old) in their sense of self-continuity and life satisfaction (N = 424). Consistent with past research, older adults reported greater self-continuity compared to their young counterparts, while cross-cultural comparisons showed that young Chinese reported greater self-continuity than young Canadians. In terms of life satisfaction, older adults again scored higher than younger adults, while cross-cultural comparisons indicated that, this time, young Canadians reported higher life satisfaction than young Chinese. Although the data were cross-sectional, indirect effects analyses showed that self-continuity mediated the effect of age on life satisfaction in both cultural groups, with the indirect effect stronger among Canadians than among Chinese. These findings highlight the importance of considering culture and age when examining psychological outcomes, and the potential of self-continuity as a mechanism to enhance overall life satisfaction.

Interfacial Self-assembly of Organics/MXene Hybrid Cathodes Toward High-Rate-Performance Sodium Ion Batteries.

Conjugated quinones are promising cathode materials for sodium-ion batteries. However, the contemporary primary conjugated quinones cathodes still hold to limited capacity, poor rate performance and low cyclability, due to the poor electronic and ionic conductivity. Herein, a series of high-performance conjugated-quinones@MXene hybrid cathodes is constructed by an in situ polymerization-assembly strategy based on the hydrogen bond and S-Ti interaction. The PAQS@Ti3C2Tx MXene hybrid, as a typical example, exhibits sandwiched structure with intimate PAQS@MXene contact, resulting in efficient interfacial mass transfer. The assembled MXene is able to build interconnected conductive channels in the hybrid cathodes for continuous and fast electrons/ions transport, which is verified by both the experimental results and density functional theory (DFT) calculations. As a result, the optimal PAQS@MXene hybrid electrode delivers excellent electrochemical performances with high capacity (∼242 mA h g-1 at 100 mA g-1), superior fast-charge/discharge ability (∼148 and 121 mA h g-1 at 5 and 10 A g-1, respectively), and ultralong cycle life (capacity as high as 57 mA h g-1 after 9000 cycles at 5 A g-1), which are more superior to that of the pure PAQS electrodes. Besides, the analogous PPTS@Ti3C2Tx MXene hybrid cathode also shows better performances compared to the pure materials.

Age Differences in Leadership Positions Across Cultures.

In most countries around the world, the population is rapidly aging. A by-product of these demographic shifts is that older adults will likely occupy more positions of power and influence in our societies than ever before. Further, cultural differences might shape how these transitions unfold around the globe. Across two studies, we investigated whether business and political leaders differed in age across various cultures. Study 1 (N = 1,034) showed that business leaders were significantly older in Eastern (e.g., China, India, and Japan) cultures than Western (e.g., United States, Sweden, and United Kingdom) cultures, even while controlling for population structure (e.g., percentage of elderly in the society), gross domestic product (GDP), and wealth distribution across the population (GINI). Study 2 (N = 1,268) conceptually replicated these findings by showing that political leaders were once again older in Eastern vs. Western cultures. Furthermore, cultural tightness mediated the relationship between culture and older leadership. These findings highlight how cultural differences impact not only our preferences, but also important outcomes in consequential domains such as business and politics. Potential explanations for why cultural tightness may be related to differences in leader age across cultures are discussed. To build on these findings, future research should assess the potential causal mechanisms underlying the cultural effect on leader age, and explore the various practical implications of this effect.

Cultural Differences in People's Psychological Response to COVID-19.

The present research studied Chinese and Euro-Canadian students during the COVID-19 pandemic, focusing on their affect, optimism, well-being, and meaning in life. The results revealed both differences and similarities across cultures. As predicted, Chinese participants reported more positive affect and less negative affect, higher optimism, higher state psychological well-being, and higher meaning presence, compared to Euro-Canadian participants. The findings were replicated after a week's delay. Analyses on longitudinal data showed that state optimism, state well-being, and meaning presence influenced one another over time. These variables also mediated the cultural differences in one another. These results are consistent with cultural work on naïve dialecticism and non-linear lay theory of change. Results also demonstrate underlying relationships among the constructs that are common to both cultural groups. Broadly, the present research highlights the impact of culture on people's response to challenging life situations and the mechanisms underlying these cultural differences.

Synthesis of an organic-inorganic hybrid with short organic molecular chains by sol-gel chemistry.

An oligomer with short organic molecular chains was successfully synthesized with KH550 and KH560. This oligomer was combined with tetraethyl orthosilicate and calcium chloride to prepare an organic-inorganic hybrid biological material (OI-BM) by sol-gel chemistry. The hybrid was fully characterized by a series of instrumental characterizations including nuclear magnetic resonance spectrometry, scanning electron microscopy, transmission electron microscopy, Fourier transform infrared spectroscopy, X-ray energy spectroscopy and inductively coupled plasma spectrometry. OI-BM presented elastic deformation under compression. The elastic modulus and ultimate stress of OI-BM were 0.4 ± 0.1 GPa and 23.0 ± 4.0 MPa, respectively, lower than those of 45S5 bioactive glass (45S5-BG), whereas the strain at failure and modulus of toughness of OI-BM was about 4.5 times and 4 times higher. The hybrid is easy to form due to the improved mechanical property, suggesting excellent machining properties. The hybrid OI-BM produced hydroxyapatite in 1 h in simulated body fluid due to its excellent bioactivity. CCK-8 assay further demonstrated the desirable cytocompatibility of the hybrid. Thus, the hybrid can be a potential material for satisfying the mechanical property requirement of an implant.

Preparation of bioactive glass nanoparticles with highly and evenly doped calcium ions by reactive flash nanoprecipitation.

Nanoscale bioactive glass particles have greater bioactivity than microscale bioactive glass particles, due to their high-specific surface area and fast ion release rate in body fluid. However, preparation of bioactive glass nanoparticles (BGNPs) is difficult since calcium is not easy to be highly doped into the forming silica atom network, leading to an uneven distribution and a low content of calcium. In addition, BGNPs are usually prepared in a dilute solution to avoid agglomeration of the nanoparticles, which decreases the production efficiency and increases the cost. In this work, BGNPs are prepared by a method of the reactive flash nanoprecipitation (RFNP) as well as a traditional sol-gel method. The results indicate that the BGNPs by the RFNP present a smaller size, narrower size distribution, more uniform composition, and better bioactivity than those by the traditional sol-gel method. The obtained BGNPs have uniform compositions close to the feed values. The high and even doping of calcium in the BGNPs is achieved. This successful doping of calcium into nanoparticles by the RFNP demonstrates a promising way to effectively generate high-quality BGNPs for bone repairs.

Engineering Elastic Properties of Isostructural Molecular Perovskite Ferroelectrics via B-Site Substitution.

Managing elastic properties of ABX3 type molecular perovskite ferroelectrics is critical to their future applications since these parameters determine their service durability and reliability in devices. The abundant structural and chemical viability of these compounds offer a convenient way to manipulate their elastic properties through a facile chemical approach. Here, the elastic properties and high-pressure behaviors of two isostructural perovskite ferroelectrics, MDABCO-NH4 I3 and MDABCO-KI3 (MDABCO = N-methyl-N'-diazabicyclo[2.2.2]octonium) is systematically investigated, via the first principles calculations and high-pressure synchrotron X-ray diffraction experiments. It is show that the simple replacement of NH4 + by K+ on the B-site respectively results in up to 48.1%, 52.4%, and 56.3% higher Young's moduli, shear moduli and bulk moduli, which is attributed to the much stronger KI coordination bonding than NH4 …I hydrogen bonding. These findings demonstrate that it is possible to tune elastic properties of molecular perovskite ferroelectrics via simply varying the framework assembling interactions.

Study on Dissolution Thermodynamics and Cooling Crystallization of Rifamycin S.

The solubility data of rifamycin S were measured in isopropanol, butyl acetate, and their mixed solvents across the temperature range of 283.15-323.15 K by the gravimetric method. The results demonstrate that the solubility of rifamycin S increases with the increasing temperature in the two pure solvents, and in the mixed solvents, it increases first and then decreases with increasing butyl acetate content. The experimental data of rifamycin S in the mixed solvents were better correlated using the modified Apelblat equation and ideal model equation. Furthermore, the relevant thermodynamic parameters of the dissolution process were determined based on the van't Hoff equation. The obtained dissolution enthalpy and Gibbs free energy are positive in all cases, which indicate that the dissolving process of rifamycin S is endothermic and nonspontaneous. The supersolubility data of rifamycin S were measured by the laser and thermal analytic method. The results demonstrate that the width of the metastable zone of rifamycin S becomes larger with decreasing cooling rate and increasing butyl acetate content. Furthermore, the crystallization process of rifamycin S was optimized on the basis of thermodynamic research. The results showed that when V butyl acetate:V mixed solvent was 0.04, the cooling rate was 0.1 K/min, the stirring rate was 150 rpm, the final crystallization temperature was 283.15 K, and the aging time was 8 h, the purity of rifamycin S crystals could reach 98.5%, and the crystalline yield was 89.6%. After crystallization optimization, the size of rifamycin S crystals increased, and the dissolution in water was improved.

Meaning making helps cope with COVID-19: A longitudinal study.

Meaning making is a useful coping strategy in negative situations. We investigated whether making meaning in negative experiences (MINE) would help people cope with COVID-19. We conducted a three-wave longitudinal study (N = 2364) three months before, during, and after the COVID-19 outbreak in China. Results showed that participants reported increased tendency of MINE during the COVID-19 outbreak than three months before the outbreak. Moreover, both initial MINE and the increased MINE predicted less psychological distress including depression, anxiety and stress, during and three months after the outbreak. Perceived benefits and costs of the COVID-19 mediated the long-term effect of MINE. These findings not only provide novel evidence for meaning making model but also shed light on the underlying mechanism, suggesting an effective strategy to cope with stressful events such as the ongoing COVID-19 pandemic.

The relationship between search for meaning in life and symptoms of depression and anxiety: Key roles of the presence of meaning in life and life events among Chinese adolescents.

BACKGROUND: Meaning in life has been associated with greater mental health. However, previous findings are inconsistent regarding how the search for meaning in life (SML) is related to mental health issues such as symptoms of depression and anxiety. This study proposed and tested a new model to explain how the relationship between SML and symptoms of depression as well as anxiety can be moderated by life events and mediated by the presence of meaning in life (PML). METHODS: Middle and high school students (N = 1,705, 836 girls and 869 boys; Mage = 14.37, SD = 1.70) were administrated the Meaning in Life Questionnaire, Adolescent Self-Rating Life Events Checklist, Center for Epidemiologic Studies Depression Scale, and the State Anxiety Inventory. RESULTS: Results showed that the relationship between SML and symptoms of depression (or anxiety) depended on the impact of the life events experienced by the individual. In general, SML served as a beneficial or unrelated factor for those experiencing low impactful life events, but as a harmful factor for those experiencing high impactful life events. For those experiencing middle impactful life events, SML had a positive direct effect, but a negative indirect effect (through PML) on symptoms of depression (or anxiety). LIMITATIONS: Data are cross-sectional, and the present study examined only middle school students, which may limit generalizability. CONCLUSIONS: The findings indicate a complex relationship between SML and mental health. Symptoms of depression, anxiety, and other related problems may be diminished by applying training programs and policies aimed at increasing PML and reducing negative life events.
