RESUMO
BACKGROUND: It is important for nurses who work in long-term care facilities (LTCFs) to have an adequate level of computer competency due to the multidisciplinary and comprehensive nature of long-term care services. Thus, it is important to understand the current computer competency of nursing staff in LTCFs and the factors that relate to this competency. PURPOSE: To explore the computer competency of LTCF nurses and to identify the demographic and computer-usage characteristics that relate significantly to computer competency in the LTCF environment. METHODS: A cross-sectional research design and a self-report questionnaire were used to collect data from 185 nurses working at LTCFs in Taipei. RESULTS: The results found that the variables of the frequency of computer use (ß = .33), age (ß = -.30), type(s) of the software used at work (ß = .28), hours of on-the-job training (ß = -.14), prior work experience at other LTCFs (ß = -.14), and Internet use at home (ß = .12) explain 58.0% of the variance in the computer competency of participants. CONCLUSIONS / IMPLICATIONS FOR PRACTICE: The results of the present study suggest that the following measures may help increase the computer competency of LTCF nurses. (1) Nurses should be encouraged to use electronic nursing records rather than handwritten records. (2) On-the-job training programs should emphasize participant competency in the Excel software package in order to maintain efficient and good-quality of LTC services after implementing of the LTC insurance policy.

The NLRP3 inflammasome is a caspase-1-containing multi-protein complex that controls the release of IL-1ß and plays important roles in the development of inflammatory disease. Here, we report that resveratrol, a polyphenolic compound naturally produced by plants, inhibits NLRP3 inflammasome-derived IL-1ß secretion and pyroptosis in macrophages. Resveratrol inhibits the activation step of the NLRP3 inflammasome by suppressing mitochondrial damage. Resveratrol also induces autophagy by activating p38, and macrophages treated with an autophagy inhibitor are resistant to the suppressive effects of resveratrol. In addition, resveratrol administration mitigates glomerular proliferation, glomerular sclerosis, and glomerular inflammation in a mouse model of progressive IgA nephropathy. These findings were associated with decreased renal mononuclear leukocyte infiltration, reduced renal superoxide anion levels, and inhibited renal NLRP3 inflammasome activation. Our data indicate that resveratrol suppresses NLRP3 inflammasome activation by preserving mitochondrial integrity and by augmenting autophagy.

This study explores the intersection of creative travel and flow experiences among foreign students, a topic not extensively explored in tourism research. Specifically, it examines the mediating role of flow experiences in the relationship between students' novelty-seeking behaviors and their intention to engage in creative travel. Additionally, the research investigates how familiarity with a destination moderates this relationship. Employing structural equation modeling, the study analyzes data from 704 Chinese students in Thailand. The findings reveal that flow experiences positively mediate the link between the students' pursuit of novelty and their creative travel intentions. Moreover, the extent of familiarity with the destination was found to modify the relationship between novelty seeking and flow experiences. This research contributes to the theoretical understanding of these dynamics and offers practical insights for stakeholders in creative travel marketing and management.
RESUMO
This study investigates the impact of organizational commitment and job engagement on service quality, while integrating the influences of organizational climate and emotional labor. Utilizing data from 427 participants, acquired via structured questionnaires, the research employed the Statistical Package for the Social Sciences (SPSS) for analysis. The findings reveal that heightened job engagement and organizational commitment significantly enhance service quality, primarily through reinforcing employees' trust in their organization. A favorable organizational climate is instrumental in strengthening employees' affiliation with their organization, consequently leading to superior service provision. Furthermore, the capability to effectively regulate emotions emerges as a critical factor in both job engagement and the quality of service. The study advocates for augmenting job engagement and organizational commitment, cultivating a supportive workplace atmosphere, and equipping employees with resources for efficient emotional management. These strategies are proposed to substantially improve service quality. The insights derived from this research provide essential directives for managers striving to achieve service excellence.
RESUMO
The Multidimensional Psychological Flexibility Inventory (MPFI) is a new 60-item self-report scale developed to assess the specific components of psychological flexibility and inflexibility proposed in the Hexaflex model of Acceptance and Commitment Therapy (ACT). The present study sought to examine the psychometric properties of the Persian version of the MPFI-60 in a community sample of 307 Iranian adults. The original study supported a 12-factor second-order structure consisting of 6 dimensions for psychological flexibility and 6 dimensions for psychological inflexibility. The Persian MPFI-60 demonstrated acceptable semantic and test content, internal structure, correlations with other variables, and internal consistency. It also evidenced in relation to anxiety, stress, depression, and self-compassion. Overall, the results indicate that the Persian MPFI-60 is a psychometrically sound measure in the Iranian context that enables researchers and clinicians to comprehensively assess the components of psychological flexibility and inflexibility within the Hexaflex model.
RESUMO
Herein, we report the highly efficient total syntheses of galanthamine and lycoramine from a common tetracyclic intermediate. This concise synthetic route features a two-phase strategy, which includes the early-stage rapid construction of a tetracyclic skeleton followed by the late-stage selective reorganization of the tetracyclic skeleton. Key to the success of this strategy are a palladium-catalyzed carbonylative cascade annulation, a DDQ-mediated intramolecular regioselective oxidative lactamization, as well as a BF3·Et2O-promoted reorganization of the bridged tetracyclic skeleton.
RESUMO
Rapid construction of molecules bearing all-substituted quaternary stereocenters represents a highly significant but challenging task in organic synthesis. Herein, we report a novel palladium-catalyzed cascade between alkene-tethered aryl iodides and carbon monoxide, which has resulted in a practical and powerful method for the synthesis of complex polycyclic molecules containing aryl-substituted quaternary stereocenters. Mechanistic studies suggested that the reaction proceeded via a Heck-type carbonylative cyclization, followed by a ketene-involved Friedel-Crafts acylation.
RESUMO
BACKGROUND: Hyperphosphatemia in end-stage renal disease patients is prevalent and associated with increasing cardiac mortality. Restricting dietary phosphate intake is a key element in controlling hyperphosphatemia, but most patients fail due to lack of knowledge and sustainability. In this study, we aimed to examine whether incorporating a smartphone application (APP) into a multidisciplinary caring system can decrease the prevalence of hyperphosphatemia in hemodialysis patients. METHODS: We designed a quasi-experimental study to enroll patients undergoing regular hemodialysis and assigned them to receive APP-assisted caring program (ACP group, n = 30) or standard education caring program (SCP group, n = 30). Both caring programs targeting dietary phosphate control were administered. Patients' general characteristics, self-care efficacy scales, knowledge test of phosphate control, and results of monthly blood biochemistry were analyzed. FINDINGS: Knowledge of diet phosphate control and self-care efficacy were significantly higher in the ACP group. Notably, the knowledge improvement was higher in patients aged over 60 years. Compared to the SCP group, the percentage of patients with successful hyperphosphatemia control was significantly higher in the ACP group (p = 0.0398). CONCLUSION: The APP-assisted caring program benefits patients with regular hemodialysis to achieve better dietary phosphate control without compromising proper protein intake.

Mosaicism, known as partial aneuploidies, mostly originates from mitotic errors during the post-zygotic stage; it consists of different cell lineages within a human embryo. The incidence of mosaicism has not been shown to correlate with maternal age, and its correlation with individual chromosome characteristics has not been well investigated. In this study, the results of preimplantation genetic testing for aneuploidy (PGT-A) derived from 4,036 blastocysts (930 IVF couples) were collected from 2015 to 2017. Via next-generation sequencing for comprehensive chromosome screening, embryo ploidy was identified as aneuploid, mosaic, and euploid. Total mosaicism was classified into two categories: "mosaic euploid/aneuploidy" (with mosaic aneuploidy between 20 and 80%) and "mosaic and aneuploidy" (a uniformly abnormal embryo superimposed with mosaic aneuploidies). Frequency of mosaicism was analyzed according to the function of chromosomal lengths, which divides involved chromosomes into three groups: group A (156-249 Mb), group B (102-145 Mb), and group C (51-90 Mb). The results show that the aneuploidy was more frequent in group C than in group A and group B (A: 23.7%, B: 35.1, 41.2%, p < 0.0001), while the mosaicism was more frequent in group A and group B than in group C [(Mosaic euploid/aneuploid) A: 14.6%, B: 12.4%, C: 9.9%, p < 0.0001; (mosaic and aneuploid) A: 21.3%, B: 22.9%, C: 18.9%, p < 0.0001; (Total mosaicism) A: 35.9%, B: 35.3%, C: 28.8%, p < 0.0001]. The significantly higher frequency of aneuploidy was on the shorter chromosome (< 90 Mb), and that of mosaicism was on the longer chromosomes (> 100 Mb). The length association did not reach significance in the patients with advanced age (≥ 36 years), and of the chromosome-specific mosaicism rate, the highest prevalence was on chromosome 14 (5.8%), 1 (5.7%), and 9 (5.6%). Although the length association was observed via group comparison, there may be affecting mechanisms other than chromosomes length. Eventually, twenty patients with mosaic embryo cryotransfers resulted in six live births. No significant correlation was observed between the transfer outcomes and chromosome length; however, the analysis was limited by small sample size.
RESUMO
Protein malonylation, a reversible post-translational modification of lysine residues, is associated with various biological functions, such as cellular regulation and pathogenesis. In proteomics, to improve our understanding of the mechanisms of malonylation at the molecular level, the identification of malonylation sites via an efficient methodology is essential. However, experimental identification of malonylated substrates via mass spectrometry is time-consuming, labor-intensive, and expensive. Although numerous methods have been developed to predict malonylation sites in mammalian proteins, the computational resource for identifying plant malonylation sites is very limited. In this study, a hybrid model incorporating multiple convolutional neural networks (CNNs) with physicochemical properties, evolutionary information, and sequenced-based features was developed for identifying protein malonylation sites in mammals. For plant malonylation, multiple CNNs and random forests were integrated into a secondary modeling phase using a support vector machine. The independent testing has demonstrated that the mammalian and plant malonylation models can yield the area under the receiver operating characteristic curves (AUC) at 0.943 and 0.772, respectively. The proposed scheme has been implemented as a web-based tool, Kmalo (https://fdblab.csie.ncu.edu.tw/kmalo/home.html), which can help facilitate the functional investigation of protein malonylation on mammals and plants.

AIM: To investigate the in vivo anti-tumor effect of K(8)(C(6)H(11)N(3)O(2))(2)[SiW(9)Ti(3)O(40)] (WT) and the immunological mechanism. METHODS: WT was administrated intragastrically to mice bearing H22 hepatocarcinoma for 10 days and then the tumors were isolated and weighed. MTT colorimetry was used to detect lymphocyte transformation function and cytotoxicity of NK cells. The morphology of apoptotic tumor cells was observed under phase contrast microscope and light microscope after HE staining. The apoptosis rate of BEL-7402 cells treated with WT was detected by flow cytometry. RESULTS: Compared to the control group, WT obviously inhibited the growth of H22 tumor in tumor bearing mice (P<0.05). It enhanced significantly lymphocyte transformation function and cytotoxicity of NK cells (P<0.05). Apoptotic tumor cells were observed under microscope and detected by flow cytometry. CONCLUSION: WT inhibits significantly the growth of tumor by up-regulating the activity of immunocytes and inducing apoptosis of tumor cells.
