RESUMEN

OBJECTIVE: We investigated the relationship between personal relative deprivation (PRD)-resentment from the belief that one is worse off than people who are similar to oneself-and locus of control. BACKGROUND: Research has yet to comprehensively investigate whether PRD is associated with a tendency to favor external (vs. internal) explanations for self- and other-relevant outcomes. METHOD: Eight studies (Ntotal = 6729) employed cross-sectional, experimental, and (micro)longitudinal designs and used established trait and state measures of PRD and loci of control. RESULTS: Participants higher in PRD adopted more external (vs. internal) explanations for others' outcomes while controlling for socio-demographics (e.g., socioeconomic status; Studies 1-4). This relationship was mediated by a lowered sense of personal control (Study 1) and evident in a cross-national sample of participants in Asia (Study 2). PRD is more robustly associated with external than internal explanations for self and other-relevant outcomes (Studies 5-8), and within-person changes in PRD are positively associated with within-person changes in external explanations (month-to-month and day-to-day; Studies 7-8). CONCLUSIONS: PRD is positively associated with external locus of control independent of socioeconomic status, within and between people, and across cultures. This research highlights the implications of PRD for people's construal of the causal forces that govern their lives.

RESUMEN

Previous research has suggested that empathic concern may affect cultural differences in social support-seeking. However, neither the mechanisms through which empathic concern promotes support-seeking nor the explanations for cultural differences in empathic concern are clear. This study attempted to address these questions by conducting three studies in Japan and the United States. The results showed that Japanese participants reported having lower trait-empathic concern and seeking less social support in dealing with stress than European Americans. Study 1 found that trait-empathic concern mediated the cultural differences in support-seeking by increasing beliefs about others' prosocial willingness. Using a controlled set of stressful scenarios, Study 2 replicated the results of Study 1. Additionally, Study 2 showed that Japanese participants reported greater endorsement of the causal repressive suffering construal than European Americans, partly accounting for cultural differences in trait-empathic concern. Using an experimental design, Study 3 showed that primed empathic concern increased support-seeking in coping with follow-up stress across cultures. These findings contribute to our understanding of the role of empathic concern in support-seeking and cultural differences in empathic concern.

RESUMEN

Purpose: Endometrial cancer (EC) is one of the most common types of cancer affecting women. While the hematoxylin-and-eosin (H&E) staining remains the standard for histological analysis, the immunohistochemistry (IHC) method provides molecular-level visualizations. Our study proposes a digital staining method to generate the hematoxylin-3,3'-diaminobenzidine (H-DAB) IHC stain of Ki-67 for the whole slide image of the EC tumor from its H&E stain counterpart. Approach: We employed a color unmixing technique to yield stain density maps from the optical density (OD) of the stains and utilized the U-Net for end-to-end inference. The effectiveness of the proposed method was evaluated using the Pearson correlation between the digital and physical stain's labeling index (LI), a key metric indicating tumor proliferation. Two different cross-validation schemes were designed in our study: intraslide validation and cross-case validation (CCV). In the widely used intraslide scheme, the training and validation sets might include different regions from the same slide. The rigorous CCV validation scheme strictly prohibited any validation slide from contributing to training. Results: The proposed method yielded a high-resolution digital stain with preserved histological features, indicating a reliable correlation with the physical stain in terms of the Ki-67 LI. In the intraslide scheme, using intraslide patches resulted in a biased accuracy (e.g., R = 0.98 ) significantly higher than that of CCV. The CCV scheme retained a fair correlation (e.g., R = 0.66 ) between the LIs calculated from the digital stain and its physical IHC counterpart. Inferring the OD of the IHC stain from that of the H&E stain enhanced the correlation metric, outperforming that of the baseline model using the RGB space. Conclusions: Our study revealed that molecule-level insights could be obtained from H&E images using deep learning. Furthermore, the improvement brought via OD inference indicated a possible method for creating more generalizable models for digital staining via per-stain analysis.

RESUMEN

PURPOSE: This study, by applying the feedback process of the organizational learning model, examined the relationships among group learning, individuals' and groups' internalization of institutionalized evidence-based practice (I-EBP), and nurses' sustainment of I-EBP. DESIGN/METHODOLOGY/APPROACH: Twelve hospitals were included in this cross-sectional study, with 1,741 nurses from 59 wards. Anonymous questionnaires were administered from October to December 2021. Participants self-reported their wards' group learning, internalization of I-EBP, sustainment of I-EBP, EBP beliefs, intra-hospital transfers, and nursing research experiences. The number of nurses and I-EBP introduction length and type of I-EBP were assessed. Internalization of I-EBP of nurses and groups was considered the mediating variable, while group learning and nurses' sustainment of I-EBP were the independent and dependent variables, respectively. Significant variables in bivariate analyses were used as control variables. Multi-level Mediation Analysis and a significance test of indirect effect using the bootstrap method were conducted. FINDINGS: Responses from 360 nurses in 48 wards from 12 hospitals were analyzed. Groups' internalization of I-EBP significantly mediated the relationship between group learning and nurses' sustainment of I-EBP. In contrast, no significant mediating effect of nurses' internalization of I-EBP was observed. ORIGINALITY/VALUE: In the feedback process of organizational learning, group learning and its subsequent effects on individuals and groups have not been previously examined. Regardless of the nurses' degree of internalization of I-EBP, those who belong to the ward with a high degree of internalization of I-EBP are more likely to sustain it. Conducting group learning may prevent superficial practice, resulting in its sustainability.

RESUMEN

It is well-known that the caudate nucleus is associated with motivational behaviors and subjective well-being. However, no longitudinal studies have examined the relationship between brain structure, behavioral orientations, and subjective well-being. This study analyzes data from our previous longitudinal study to examine whether future subjective well-being can be predicted by the volume of the caudate nucleus. We also examined whether behavioral orientation, based on the regulatory focus theory showing two orientations-promotion and prevention focus-was related to the volume of the caudate nucleus. Voxel-based morphometry analysis indicated that the left caudate volume was positively associated with rating scores for future subjective well-being and promotion orientation. Further, mediation analysis indicated that promotion orientation significantly mediated the relationship between future subjective well-being and left caudate volume. The findings indicate that future subjective well-being can be predicted by the volume of the left caudate nucleus, and that this relationship is mediated by promotion focus orientation.

RESUMEN

Cryptococcus deneoformans is a yeast-type fungus that causes fatal meningoencephalitis in immunocompromised patients and evades phagocytic cell elimination through an escape mechanism. Memory T (Tm) cells play a central role in preventing the reactivation of this fungal pathogen. Among these cells, tissue-resident memory T (TRM) cells quickly respond to locally invaded pathogens. This study analyzes the kinetics of effector T (Teff) cells and Tm cells in the lungs after cryptococcal infection. Emphasis is placed on the kinetics and cytokine expression of TRM cells in the early phase of infection. CD4+ Tm cells exhibited a rapid increase by day 3, peaked at day 7, and then either maintained their levels or exhibited a slight decrease until day 56. In contrast, CD8+ Tm cells reached their peak on day 3 and thereafter decreased up to day 56 post-infection. These Tm cells were predominantly composed of CD69+ TRM cells and CD69+ CD103+ TRM cells. Disruption of the CARD9 gene resulted in reduced accumulation of these TRM cells and diminished interferon (IFN) -γ expression in TRM cells. TRM cells were derived from T cells with T cell receptors non-specific to ovalbumin in OT-II mice during cryptococcal infection. In addition, TRM cells exhibited varied behavior in different tissues. These results underscore the importance of T cells, which produce IFN-γ in the lungs during the early stage of infection, in providing early protection against cryptococcal infection through CARD9 signaling.

RESUMEN

BACKGROUND: Organizational learning (OL) and interprofessional collaboration (IPC) are said to enhance medical safety in hospitals, but the relationship between these variables has not been quantitatively tested. OBJECTIVE: This study examines the mediating effects of IPC on the relationship between OL and safety climate (improvement, compliance, and patient/family involvement). METHODS: An anonymous self-reporting questionnaire was administered to 1,495 healthcare workers from November 2021 to January 2022. The questions regarded the hospital's safety climate, OL, and IPC. A mediation analysis using structural equation modeling was conducted to examine the mediating role of IPC on the relationship between OL and the three safety climates. The indirect effect was estimated using 2,000 bootstrap samples. RESULTS: Responses from 643 healthcare workers were analyzed. The direct effects of OL were 𝛽 = .74, 75 (p < .001) on improvement and involvement and 𝛽 = 0.1 (p > .05) on compliance. The indirect effects of IPC on improvement and involvement were 𝛽 = .14 (95%CI: .00 ∼ .06) and 𝛽 = .37 (95%CI: .04 ∼ .09), respectively. CONCLUSION: This study determined the mechanisms that enhance a hospital's safety climate, demonstrating that IPC mediates the relationship between OL and improvement and patient/family involvement. However, OL and IPC are not related to compliance.

RESUMEN

Using data from 15 countries, this article investigates whether descriptive and prescriptive gender norms concerning housework and child care (domestic work) changed after the onset of the COVID-19 pandemic. Results of a total of 8,343 participants (M = 19.95, SD = 1.68) from two comparable student samples suggest that descriptive norms about unpaid domestic work have been affected by the pandemic, with individuals seeing mothers' relative to fathers' share of housework and child care as even larger. Moderation analyses revealed that the effect of the pandemic on descriptive norms about child care decreased with countries' increasing levels of gender equality; countries with stronger gender inequality showed a larger difference between pre- and post-pandemic. This study documents a shift in descriptive norms and discusses implications for gender equality-emphasizing the importance of addressing the additional challenges that mothers face during health-related crises.

RESUMEN

Evidence suggests that Latin Americans display elevated levels of emotional expressivity and positivity. Here, we tested whether Latin Americans possess a unique form of interdependence called expressive interdependence, characterized by the open expression of positive emotions related to social engagement (e.g., feelings of closeness to others). In Study 1, we compared Latin Americans from Chile and Mexico with European Americans in the United States, a group known to be highly independent. Latin Americans expressed positive socially engaging emotions, particularly in response to negative events affecting others, whereas European Americans favored positive socially disengaging emotions, such as pride, especially in response to personally favorable circumstances. Study 2 replicated these findings with another group of Latin Americans from Colombia and European Americans in the United States. Study 2 also included Japanese in Japan, who expressed positive emotions less than Latin and European Americans. However, Japanese displayed a higher tendency to express negative socially engaging emotions, such as guilt and shame, compared to both groups. Our data demonstrate that emotional expression patterns align with overarching ethos of interdependence in Latin America and Japan and independence among European Americans. However, Latin Americans and Japanese exhibited different styles of interdependence. Latin Americans were expressive of positive socially engaging emotions, whereas Japanese were less expressive overall. Moreover, when Japanese expressed emotions, they emphasized negative socially engaging emotions. Implications for theories of culture and emotion are discussed.

RESUMEN

OBJECTIVES: Previous studies have indicated that good human relationships contribute significantly to subjective well-being. We recently focused on two important ways of developing good interpersonal relationships: positive empathy, which focuses on the happiness of other people, and trait forgivingness, a tendency to forgive others. We novelly conducted an exploratory genome-wide association study (GWAS) to identify candidate gene polymorphisms associated with positive empathy and trait forgivingness among the Japanese. MATERIAL AND METHODS: We for the first time identified several genetic polymorphisms associated with positive empathy and trait forgivingness through the GWAS based on a small sample population and relatively low threshold. We subsequently validated three genetic polymorphisms from these candidate genes using a real-time polymerase chain reaction system. RESULTS: The results demonstrated that polymorphism in the vomeronasal type-1 receptor 1 (VN1R1) (rs61744949), a putative human pheromone receptor, is associated with positive empathy. In addition, genetic polymorphisms in the 5-hydroxytryptamine (serotonin) receptor 7 (HTR7: rs77843021) and tyrosine 3-monooxygenase/tryptophan 5-monooxygenase activation protein, epsilon (YWHAE: rs9908013), which are associated with dopamine and serotonin biosynthesis, are associated with trait forgivingness. CONCLUSION: This study novelly illustrated the influence of the genetic polymorphism in VN1R1 on positive empathy and that of genetic polymorphisms in HTR7 and YWHAE on trait forgivingness. It identified a relationship between previously unreported genetic polymorphisms and the necessary abilities for developing good human relationships. This will significantly impact future research on positive psychology and social psychology.

RESUMEN

BACKGROUND: An increasing number of women are undergoing breast implantation for cosmetic purposes and for reconstructive purposes after breast excision. The surface morphology of the breast implant is one of the key factors associated with the induction of capsule contraction. The effect of surface morphology on the inflammatory response following implant insertion remains unclear, however. This study conducted comparative analyses to determine the effect of the textured and smooth surface morphology of silicone sheets. METHODS: Each type of silicone sheet was inserted into the subcutaneous pocket below the panniculus carnosus in C57BL/6 mice and mice with genetic disruption of CARD9, Dectin-1, Dectin-2, or Mincle. We also analyzed the collagen fiber capsule thickness, histological findings, and macrophage inflammatory response, including TGF-ß synthesis. RESULTS: We found that textured surface morphology contributed to the formation of collagen fiber capsules and the accumulation of fibroblasts and myofibroblasts, and was accompanied by the accumulation of TGF-ß-expressing macrophages and foreign-body giant cells. CARD9 deficiency attenuated collagen fiber capsule formation, macrophage responses, and TGF-ß synthesis, although the responsible C-type lectin receptors (CLRs) remain to be clarified. CONCLUSIONS: These results suggest that CARD9 may have a strong impact on silicone sheet insertion through the regulation of macrophage responses.

RESUMEN

Of late, internet addiction among adolescents has become a serious problem, with increased internet use. Previous research suggests that the more people become addicted to the internet, the more they isolate themselves from society. Conversely, it has been suggested that abundant social capital (the networks of relationships among people who live and work in a particular society) protects people from becoming addicted to the internet. This study focused on the brain structure of typical adolescents (10-18 years of age) and hypothesized that the size of the left dorsolateral prefrontal cortex (DLPFC), which is thought to be associated with self-control ability, is associated with both internet addiction and social capital. Voxel-based morphometry analysis indicated that left DLPFC volume was negatively correlated with the severity of internet addiction and positively correlated with social capital. Furthermore, correlation analysis demonstrated that the severity of internet addiction and social capital were negatively correlated. The statistical association between them was no longer significant when left DLPFC volume was used as a control variable. These results suggest that the left DLPFC may mediate the relationship between social capital and internet addiction in adolescents.

RESUMEN

Optimal conditions for wound healing require a smooth transition from the early stage of inflammation to proliferation, and during this time alternatively activated (M2) macrophages play a central role. Recently, heat-killed lactic acid bacteria (LAB), such as Lactobacillus plantarum (L. plantarum) have been reported as possible modulators affecting the immune responses in wound healing. However, how signaling molecules regulate this process after the administration of heat-killed LAB remains unclear. In this study, we examined the effect of heat-killed L. plantarum KB131 (KB131) administration on wound healing and the contribution of CARD9, which is an essential signaling adaptor molecule for NF-kB activation upon triggering through C-type lectin receptors, in the effects of this bacterium. We analyzed wound closure, histological findings, and inflammatory responses. We found that administration of KB131 accelerated wound closure, re-epithelialization, granulation area, CD31-positive vessels, and α-SMA-positive myofibroblast accumulated area, as well as the local infiltration of leukocytes. In particular, M2 macrophages were increased, in parallel with CCL5 synthesis. The acceleration of wound healing responses by KB131 was canceled in CARD9-knockout mice. These results indicate that the topical administration of KB131 accelerates wound healing, accompanying increased M2 macrophages, which suggests that CARD9 may be involved in these responses.

RESUMEN

This research explores how culture influences the motivations underlying explicit (emotional and instrumental) and implicit (companionship and attentiveness) support provision. Two studies (N = 1,106) compared the responses of European Americans and Japanese individuals to a close other's stressful event. The results showed that European Americans were more likely than Japanese to provide explicit support and more motivated to increase the close other's self-esteem and feeling of closeness. Conversely, Japanese individuals were more likely to provide attentiveness support, motivated by concern for an entire group and a friend. These findings support the motivation as a mediator hypothesis. On the other hand, the culture as a moderator hypothesis applied to the association between concern for an entire group motivation and implicit support provision. Specifically, concern for an entire group motivation predicted companionship support provision only in Japanese, while it predicted attentiveness support provision mainly in European Americans.

RESUMEN

INTRODUCTION: Lobular endocervical glandular hyperplasia (LEGH) is a benign lesion; however, it is considered to be the origin of gastric-type adenocarcinoma in the uterine cervix, and early diagnosis is important. At Shinshu University Hospital, screening of LEGH cells is based on the difference in color tone of cytoplasmic mucin on Papanicolaou staining and detection of gastric mucin using HIK1083-labeled latex agglutination assay. However, it is sometimes difficult to distinguish LEGH cells with subtle nuclear atypia from endocervical (EC) cells. METHODS: We calculated the Gabor filter features (mean signal value, standard deviation, skewness, kurtosis) from the nuclei of cytological specimens in EC cells (37 cases) and LEGH cells (33 cases) using microscopic images, and we performed statistical analysis and discriminant analysis by linear support vector machine (LSVM) using these features. A Gabor filter is a linear filter defined as a mathematical representation of the mammalian visual system. Gabor filters with three wavelengths and eight angles were used for analysis. RESULTS: Gabor filter features in EC cells were higher than in LEGH cells, demonstrating that the gradient of LEGH cell nuclei was milder than that of EC cell nuclei. The accuracy calculated using all Gabor filters was 91.0% and the accuracy of four Gabor filters (λ = 2/3π and θ = 0°, 45°, 90°, 135°) was 88.9%. High accuracy with low computation costs was achieved by reducing the number of features used for LSVM. CONCLUSION: The application of a Gabor filter with convolutional processing resulted in the edges of LEGH cells being slightly rough and thick, whereas those of EC cells were fine and thin. Thus, it is thought that the frequency of abrupt gradients of pixels was higher in EC cells than in LEGH cells, and the gradient of chromatin distribution in LEGH cell nuclei was milder than that in EC cell nuclei. It was possible to evaluate nuclear findings of EC and LEGH cells objectively by quantifying morphological features of nuclei using Gabor filters. It was possible to differentiate EC cells from LEGH cells using LSVM using Gabor filter features.

RESUMEN

Social science research has highlighted "honor" as a central value driving social behavior in Mediterranean societies, which requires individuals to develop and protect a sense of their personal self-worth and their social reputation, through assertiveness, competitiveness, and retaliation in the face of threats. We predicted that members of Mediterranean societies may exhibit a distinctive combination of independent and interdependent social orientation, self-construal, and cognitive style, compared to more commonly studied East Asian and Anglo-Western cultural groups. We compared participants from eight Mediterranean societies (Spain, Italy, Greece, Turkey, Cyprus [Turkish Cypriot and Greek Cypriot communities], Lebanon, Egypt) to participants from East Asian (Korea, Japan) and Anglo-Western (the United Kingdom, the United States) societies, using six implicit social orientation indicators, an eight-dimensional self-construal scale, and four cognitive style indicators. Compared with both East Asian and Anglo-Western samples, samples from Mediterranean societies distinctively emphasized several forms of independence (relative intensity of disengaging [vs. engaging] emotions, happiness based on disengaging [vs. engaging] emotions, dispositional [vs. situational] attribution style, self-construal as different from others, self-directed, self-reliant, self-expressive, and consistent) and interdependence (closeness to in-group [vs. out-group] members, self-construal as connected and committed to close others). Our findings extend previous insights into patterns of cultural orientation beyond commonly examined East-West comparisons to an understudied world region.

RESUMEN

Introduction: Social support-seeking is considered to be an effective way for international students to cope with their acculturative stress and contribute to cross-cultural adaptation. In addition to support from people in the host country (close support), the ease of online communication now allows international students to receive additional support from people back in their home country (distant support). However, little research has investigated whether distant support works as effectively as close support. In two studies, we examined the differential effect of distant and close support-seeking on the psychological adaptation of Chinese international students in the host country and how acculturation orientations relate to the use of these two types of support. Methods: Chinese international students in Japan (Study 1; N = 172) and the United States (Study 2; N = 118) completed an online survey that assessed participants' host/home culture orientation, distant emotional/instrumental support-seeking, close emotional/instrumental support-seeking, and psychological adaptation. Results: Results showed that distant emotional support-seeking negatively predicted psychological adaptation in the host country. Nevertheless, distant emotional support-seeking alleviated feelings of loneliness in Chinese international students as close emotional support-seeking did (Study 2). Also, the results showed that international students with higher home-culture orientation sought more distant support, whereas those with higher host-culture orientation sought more close support. Further, Chinese-culture orientation increased distant emotional support-seeking, decreasing psychological adaptation as well as loneliness. Discussion: These findings highlight the importance of considering the source and types of support when discussing the implications of social support for the cross-cultural adaptation of international students.

RESUMEN

TiNbSn alloy is a high-performance titanium alloy which is biosafe, strong, and has a low Young's modulus. TiNbSn alloy has been clinically applied as a material for orthopedic prosthesis. Anodized TiNbSn alloys with acetic and sulfuric acid electrolytes have excellent biocompatibility for osseointegration. Herein, TiNbSn alloy was anodized in a sulfuric acid electrolyte to determine the antimicrobial activity. The photocatalytic activities of the anodic oxide alloys were investigated based on their electronic band structure and crystallinity. In addition, the cytotoxicity of the anodized TiNbSn alloy was evaluated using cell lines of the osteoblast and fibroblast lineages. The antimicrobial activity of the anodic oxide alloy was assessed according to the ISO 27447 using methicillin-susceptible Staphylococcus aureus, methicillin-resistant Staphylococcus aureus, and Escherichia coli. The anodic oxide comprised rutile and anatase titanium dioxide (TiO2) and exhibited a porous microstructure. A well-crystallized rutile TiO2 phase was observed in the anodized TiNbSn alloy. The methylene blue degradation tests under ultraviolet illumination exhibited photocatalytic activity. In antimicrobial tests, the anodized TiNbSn alloy exhibited robust antimicrobial activities under ultraviolet illumination for all bacterial species, regardless of drug resistance. Therefore, the anodized TiNbSn alloy can be used as a functional biomaterial with low Young's modulus and excellent antimicrobial activity.

RESUMEN

The current research examines cross-cultural differences in people's daily stress experiences and the role of social orientations in explaining their experiences. Using a situation sampling method, Study 1 collected European Canadian and Japanese undergraduates' examples of stressful interpersonal and non-interpersonal situations they experienced, measuring participants' perception of the intensity and frequency of each type of situation. Studies 2 and 3 examined the effects of culture on participants' reports of stress symptoms under the situations. Study 3 assessed the mediating effects of independence and interdependence between culture and perceived stress. These studies indicated that the situational context moderates the effect of culture on perceptions of stress, showing a different amount of stress from interpersonal situations between Japanese and European Canadian undergraduates. Mediational analyses revealed that independent orientation partially explains the relationship between culture and stress from interpersonal situations. The implications of these results for culture and daily stress are discussed.

RESUMEN

OBJECTIVE: People's psychological tendencies are attuned to their sociocultural context and culture-specific ways of being, feeling, and thinking are believed to assist individuals in successfully navigating their environment. Supporting this idea, a stronger "fit" with one's cultural environment has often been linked to positive psychological outcomes. The current research expands the cultural, conceptual, and methodological space of cultural fit research by exploring the link between well-being and honor, a central driver of social behavior in the Mediterranean region. METHOD: Drawing on a multi-national sample from eight countries circum-Mediterranean (N = 2257), we examined the relationship between cultural fit in honor and well-being at the distal level (fit with one's perceived society) using response surface analysis (RSA) and at the proximal level (fit with one's university gender group) using profile analysis. RESULTS: We found positive links between fit and well-being in both distal (for some, but not all, honor facets) and proximal fit analyses (across all honor facets). Furthermore, most fit effects in the RSA were complemented with positive level effects of the predictors, with higher average honor levels predicting higher well-being. CONCLUSIONS: Our findings highlight the interplay between individual and environmental factors in honor as well as the important role honor plays in well-being in the Mediterranean region.
