Enhanced oxygen evolution and power density of Co/Zn@NC@MWCNTs for the application of zinc-air batteries.

Rechargeable zinc-air batteries (ZABs) are viewed as a promising solution for electric vehicles due to their potential to provide a clean, cost-effective, and sustainable energy storage system for the next generation. Nevertheless, sluggish kinetics of the oxygen evolution reaction (OER), the oxygen reduction reaction (ORR) at the air electrode, and low power density are significant challenges that hinder the practical application of ZABs. The key to resolving the development of ZABs is developing an affordable, efficient, and stable catalyst with bifunctional catalytic. In this study, we present a series of bifunctional catalysts composed of Co/Zn nanoparticles uniformly embedded in nitrogen-doped carbon (NC) and multi-walled carbon nanotubes (MWCNTs) denoted as Co/Zn@NC@MWCNTs. The incorporation of MWCNTs using a facile and non-toxic method significantly decreased the overpotential of the OER from 570 to 430 mV at 10 mA cm-2 and the peak power density from 226 to 263 mW cm-2. Besides, the electrochemical surface area measurements and electrochemical impedance spectroscopy indicate that the three-dimensional (3D) network structure of MWCNTs facilitates mass transport for ORR and reduces electron transfer resistance during OER, leading to a small potential gap of 0.86 V between OER and ORR, high electron transfer number (3.92-3.98) of the ORR, and lowest Tafel slope (47.8 mV dec-1) of the OER in aqueous ZABs. In addition, in-situ Raman spectroscopy revealed a notable decrease in the ID/IG ratio for the optimally configured Co/Zn@NC@MWCNTs (75:25), indicating a reduction in defect density and improved structural ordering during the electrochemical process, which directly contributes to enhanced ORR activity. Hence, this study provides an excellent strategy for constructing a bifunctional catalyst material with a 3D MWCNTs conductive network for the development of advanced ZAB systems for sustainable energy applications.

Positive vaccine beliefs linked to reduced mental stress in healthcare professionals during COVID-19: a retrospective study.

Background and aim: The COVID-19 pandemic has led to a significant adverse effect on the mental health of healthcare professionals. This study aims to assess the effects of the prolonged pandemic on burnout and mood disorders and to evaluate the influence of positive vaccination beliefs on these factors at a medical center during the extended COVID-19 pandemic. Methods: This retrospective study analyzed the results of an online questionnaire survey including burnout status and mood disorders from 2020 to 2022. The factors related to mood moderate/severe disorders and the impact of the positive vaccine belief were also explored. Results: The initial analysis revealed that healthcare professionals continued to experience significant levels of personal and work-related burnout, along with mood disorders. However, the scores and the percentage of moderate to severe burnout gradually decreased. Notably, the percentage of individuals with moderate to severe mood disorders also gradually declined (2020: 13.4%, 2021: 12.3%, 2022: 11.1%). The number of participants who need professional interventions decreased from 56.2% in 2020 to 45.9% in 2021, and 46% in 2022. Multivariate analysis revealed a positive vaccine belief was associated with a lower risk of moderate/severe mood disorders, with odd ratios (OR) and 95% confidence intervals (95% CI) of 0.38 (0.28 - 0.52) and 0.41 (0.30 - 0.52) in the 2021 and 2022 cohorts, respectively. Further investigation revealed that age over 50 was linked to a positive vaccine belief in 2021 and 2022. Within the 2022 cohort, working as nurses was identified as the independent factor associated with a less positive belief, with the OR and 95% CI of 0.49 (0.27 - 0.90). Conclusion: The findings of the present study suggest burnout and mood disorders are still significant during the pandemic. A positive vaccine belief may mitigate pandemic-related mental distress. Further interventions to enhance the belief combined with other supporting measures are important in a long fight against the pandemic.

A Systematic Review and Meta-Analysis of 35,409 Patients Undergoing PCI versus CABG for Unprotected Left Main Coronary Artery Diseases.

Background: Patients with unprotected left main (UPLM) disease who underwent percutaneous coronary intervention (PCI) were found to have inconsistent results compared to those treated with coronary artery bypass grafting (CABG). Methods: We identified and enrolled randomized controlled trials (RCTs) and observational studies (OSs) comparing PCI versus CABG for UPLM disease. A meta-analysis was performed using Stata 17.0. The primary endpoints were major adverse cardiovascular and cerebrovascular events (MACCEs). Additionally, all-cause death, cardiac death, myocardial infarction (MI), stroke, target vessel revascularization (TVR), and stent thrombosis (ST) were included as secondary endpoints. The odds ratios and 95% confidence intervals (CIs) were calculated. Sensitivity analyses were implemented if I 2 > 50% or p < 0.01. Publication bias analysis was conducted if more than 10 studies were included. Results: A total of 5 RCTs and 18 OSs involving 35,409 patients were included. The CABG strategy had a significantly lower incidence of MACCEs, primarily due to TVR. A significantly lower stroke rate was observed with the PCI strategy, as well as a significantly lower all-cause death, cardiac death, MI, and ST rate compared with the CABG strategy. Conclusions: MACCE rates were significantly lower in patients who underwent CABG, primarily due to TVR, but stroke rates were higher. RCTs with different study types need further investigation to confirm the most effective strategy.

A Mitogen-Activated Protein Kinase Pathway Is Required for Bacillus amyloliquefaciens PMB05 to Enhance Disease Resistance to Bacterial Soft Rot in Arabidopsis thaliana.

When a plant is infected by a pathogen, endogenous immune responses are initiated. When the initiation of these defense responses is induced by a pathogen-associated molecular pattern (PAMP) of a pathogen, it is called PAMP-triggered immunity (PTI). Previous studies have shown that Bacillus amyloliquefaciens PMB05 can enhance PTI signals and improve disease control of bacterial soft rot and wilt in Arabidopsis thaliana. In the context of controlling bacterial wilt disease, the involvement of a mitogen-activated protein kinase (MAPK) signaling pathway has been established. Nevertheless, it remains unclear whether this pathway is also required for B. amyloliquefaciens PMB05 in controlling bacterial soft rot. In this study, A. thaliana ecotype Columbia (Col-0) and its mutants on a MAPK pathway-related pathway were used as a model and established that the ability of B. amyloliquefaciens PMB05 to control soft rot requires the participation of the MAPK pathway. Moreover, the enhancement of disease resistance by PMB05 is highly correlated with the activation of reactive oxygen species generation and stomata closure, rather than callose deposition. The spray inoculation method was used to illustrate that PMB05 can enhance stomatal closure, thereby restricting invasion by the soft rot bacterium. This control mechanism has also been demonstrated to require the activation of the MAPK pathway. This study demonstrates that B. amyloliquefaciens PMB05 can accelerate stomata closure via the activation of the MAPK pathway during PTI, thereby reducing pathogen invasion and achieving disease resistance against bacterial soft rot.

The role of cricoarytenoid joint ankylosis in bilateral vocal cord immobility.

OBJECTIVES: To stratify the severity of cricoarytenoid joint fixation (CAJF) by surgery and understand the role of it played in the bilateral vocal fold immobility (BVFI). The second objective emphasizes on the significance of the preoperative differential diagnosis from neurogenic immobility with medical history and endoscopic findings. METHODS: A retrospective review was conducted of 74 patients between 2005 and 2022. Careful medical history inquiry, and videolaryngoscopy are conducted to recruit the appropriate surgical candidates. All patients underwent arytenoid remobilization (AR) followed by vocal fold medialization with arytenoid adduction (AA) or lateralization with suture lateralization (SL). The severity of CAJF is graded during the operation or inferred based on the period from operation to recurrence. RESULT: A total of 18 patients, aged between 18 and 76 years, were analyzed. Among them, 14 cases were classified as the adducted type with ventilation problems, with three presenting with dyspnea, and 11 requiring artificial airways. Additionally, four patients presented with the abducted type, characterized by aphonia. Meanwhile, two additional cases were considered for comparison but were not included in this cohort of 18 subjects due to incorrect diagnosis and inappropriate management. Using AR procedure, the AA procedure offered three aphonia subjects a voiced sound without airway impairment and the SL procedure decannulated 100% (11/11) of the artificial airways and improved the airway patency in 100% (3/3) of the non-tracheostomized subjects despite the severity of CAJF. The severity of joint ankylosis was distributed as follows: In the aphonia group, there were three subjects with grade I, one subject with grade II, and 0 subjects with grade III. In the ventilation group, there was one subject with grade I, seven subjects with grade II, and six subjects with grade III. In contrast, the two cases used for comparison experienced recurrent dyspnea and failed decannulation because the AR procedure was not performed. The follow-up period was averaged in 58 and 14 months at least. CONCLUSION: From this experience, it is the accurate preoperative diagnosis instead of the severity of CAJF that determines the successful rate in airway patency and voiced phonation if the AR procedure is utilized. Careful medical history inquiry and videolaryngoscopic examination can correctly differentiate the mechanical from neurogenic origin without the help of EMG. Evidence of level: 4.

Un-methylation of NUDT21 represses docosahexaenoic acid biosynthesis contributing to enzalutamide resistance in prostate cancer.

AIMS: The recent approval of enzalutamide for metastatic castration-sensitive prostate cancer underscores its growing clinical significance, raising concerns about emerging resistance and limited treatment options. While the reactivation of the androgen receptor (AR) and other genes plays a role in enzalutamide resistance, identifications of novel underlying mechanism with therapeutic potential in enzalutamide-resistant (EnzaR) cells remain largely elusive. METHODS: Drug-resistant prostate cancer cell lines, animal models, and organoids were utilized to examine NUDT21 function by transcriptomic and metabolomic analyses through loss-of-function and gain-of-function assays. Notably, a mono-methylation monoclonal antibody and conditional-knockin transgenic mouse model of NUDT21 were generated for evaluating its function. RESULTS: NUDT21 overexpression acts as a crucial alternative polyadenylation (APA) mediator, supported by its oncogenic role in prostate cancer. PRMT7-mediated mono-methylation of NUDT21 induces a shift in 3'UTR usage, reducing oncogenicity. In contrast, its un-methylation promotes cancer growth and cuproptosis insensitivity in EnzaR cells by exporting toxic copper and suppressing docosahexaenoic acid (DHA) biosynthesis. Crucially, NUDT21 inhibition or DHA supplementation with copper ionophore holds therapeutic promise for EnzaR cells. CONCLUSIONS: The un-methylation of NUDT21-mediated 3'UTR shortening unveils a novel mechanism for enzalutamide resistance, and our findings offer innovative strategies for advancing the treatment of prostate cancer patients experiencing enzalutamide resistance.

The Usage of Different Hyaluronic-Acid-Containing Artificial Tears and the Treatment Outcome of Intense Pulsed Light Therapy for Dry Eye Disease: A Retrospective Cohort Study.

In this study, we aimed to investigate the effect of different hyaluronic acid (HA)-containing artificial tears on dry eye disease (DED) treatment in combination with intense pulsed light (IPL) therapy. A retrospective cohort study was conducted, and the participants received IPL therapy and HA-containing artificial tears. There were 42 and 40 eyes in the 0.10% and 0.15% HA groups after selection, respectively. The main outcomes were the postoperative non-invasive tear break-up time (NITBUT), Schirmer II test results, ocular surface stain, and numbers of DED-related symptoms. A generalized linear model was utilized to produce the adjusted odds ratio (aOR) and 95% confidence interval (CI) of the main outcomes between groups. At the three-month follow-up, the NITBUT was significantly higher in the 0.15% HA group (p = 0.023), and the NITBUT recovery was also significantly better in the 0.15% HA group compared to the 0.10% HA group (p = 0.039). The multiple DED-related symptoms significantly correlated with no DED symptom improvement in both the 0.10% and 0.15% HA groups (both p < 0.05), while the low pre-treatment NITBUT was marginally related to no DED symptom improvement in the 0.10% HA group (p = 0.047). A low NITBUT and Schirmer II test result correlated with no DED symptom improvement in both the groups (all p < 0.05). In conclusion, the application of 0.10% and 0.15% HA-containing artificial tears revealed similar effects to IPL therapy for DED.

Generative Artificial Intelligence (AI) to Uncover Insights From Breast Cancer Patients' Perceptions to Mindfulness-Based Stress Reduction (MBSR) Interventions.

The study's central objective is to harness the power of generative Artificial Intelligence (AI), in particular based on Large Language Models, as a valuable resource for delving deeper into the insights offered by patients with breast cancer (BC) who actively participated in a Mindfulness-Based Stress Reduction (MBSR) program. In a 6-week MBSR program, each session lasted 2 hours and encompassed a range of techniques, including sitting meditation, body scan, Hatha yoga, and walking meditation. A total of 25 participants were enrolled in the study. The majority of these participants reported a high level of satisfaction with the mindfulness course. The application of generative AI enabled a comprehensive analysis of the participants' responses, revealing distinct subgroups among them. The MBSR program was found to be beneficial for most participants, serving as a valuable tool in managing the psychological stresses associated with BC.

Substances use and risk of hypertension before midlife in military young adults: CHIEF cohort study, 2014-2020.

BACKGROUND: The use of substances, e.g., tobacco and betel nut, are prevalent among military personnel in Taiwan, whereas some specific substances such as alcohol use are forbidden in military base. There were inconsistent findings for the incidence of hypertension with habitual substances use in diverse populations, while no studies were carried out in the military. METHODS: A total of 2419 Taiwanese military personnel, aged 18-39 years, who were not taking any antihypertensive agents and did not have a baseline systolic blood pressure (SBP) ≥130 mmHg and/or diastolic blood pressure (DBP) ≥80 mmHg were followed for incidence of hypertension from baseline (2014) through the end of 2020. Alcohol, tobacco and betel nut use status (active vs. former/never) were self-reported by each participant at baseline. New-onset hypertension of each participant was defined by an average of two resting BP measurements in the annual health examinations (2015-2020). Multivariable Cox regression analysis with adjustments for baseline BP and other potential covariates were performed to determine the risk of incident hypertension with each substance use. Five-year absolute changes in BP level with specific substance use were compared using analysis of covariance (ANCOVA). RESULTS: There were 867 active smokers (35.8 %), 237 active betel nut chewers (9.8 %) and 961 active alcohol consumers (39.7 %) at baseline. During a median follow-up of 5.8 years, 911 new-onset hypertension events (37.7 %) were observed. While compared to those without any substances use, merely active holiday alcohol users had a significantly lower risk of incident hypertension [hazard ratio (HR) and 95 % confidence interval: 0.72 (0.58-0.89)]. The 5-year diastolic BP increase (mmHg) was borderline significantly lower in active alcohol users on holidays as compared to former/never alcohol users (4.02 (standard deviation =9.01) and 4.76 (9.42), p = 0.07). The risk of incident hypertension was not significant in active smokers and active betel nut users, while the 5-year BP increase level was significantly greater in active smokers than former/never smokers (5.60 (9.96) vs. 4.42 (9.22), p = 0.03). CONCLUSION: Our findings suggest that military young personnel consuming alcohol only allowed on holidays had a lower incidence of new-onset hypertension. On the contrary, the 5-year BP change may increase greater with habitual smoking, though the risk of new-onset hypertension was not affected.

Evaluation of the Alveolar Crest and Cemento-Enamel Junction in Periodontitis Using Object Detection on Periapical Radiographs.

The severity of periodontitis can be analyzed by calculating the loss of alveolar crest (ALC) level and the level of bone loss between the tooth's bone and the cemento-enamel junction (CEJ). However, dentists need to manually mark symptoms on periapical radiographs (PAs) to assess bone loss, a process that is both time-consuming and prone to errors. This study proposes the following new method that contributes to the evaluation of disease and reduces errors. Firstly, innovative periodontitis image enhancement methods are employed to improve PA image quality. Subsequently, single teeth can be accurately extracted from PA images by object detection with a maximum accuracy of 97.01%. An instance segmentation developed in this study accurately extracts regions of interest, enabling the generation of masks for tooth bone and tooth crown with accuracies of 93.48% and 96.95%. Finally, a novel detection algorithm is proposed to automatically mark the CEJ and ALC of symptomatic teeth, facilitating faster accurate assessment of bone loss severity by dentists. The PA image database used in this study, with the IRB number 02002030B0 provided by Chang Gung Medical Center, Taiwan, significantly reduces the time required for dental diagnosis and enhances healthcare quality through the techniques developed in this research.

Continuous Positive Airway Pressure Treatment and Hypertensive Adverse Outcomes in Pregnancy: A Systematic Review and Meta-Analysis.

Importance: Pregnancy may contribute to the development or exacerbation of obstructive sleep apnea (OSA) and increase the risk of gestational complications. Continuous positive airway pressure (CPAP) is the first-line and criterion standard treatment for OSA and is regarded as the most feasible choice during pregnancy. However, the association between CPAP therapy in pregnant women with OSA and reduced gestational complications remains inconclusive. Objective: To investigate the association between CPAP therapy in pregnant women with OSA and the reduction of adverse hypertensive outcomes during gestation. Data Sources: Keyword searches of PubMed, Embase, and the Cochrane Database of Systematic Reviews and Clinical Trials were conducted from inception to November 5, 2023. Study Selection: Original studies reporting the treatment effect of CPAP use on lowering hypertension and preeclampsia risks in pregnant women with OSA were selected. Data Extraction and Synthesis: The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guideline was followed in the reporting of reviews. Data were independently extracted by 2 authors. Random-effects model meta-analyses were performed and risk ratios (RRs) reported. Subgroup analysis, meta-regression based on age and body mass index (BMI; calculated as weight in kilograms divided by height in meters squared), and publication bias assessment were also conducted. Main Outcome and Measures: The primary outcome was the RR of gestational hypertension and preeclampsia between pregnant women with OSA receiving CPAP treatment and those who did not receive CPAP treatment. Results: Six original studies in 809 participants (mean age, 31.4 years; mean BMI, 34.0) were identified and systematically reviewed for meta-analysis. The pooled results showed significant differences between the intervention (CPAP use) and the control (non-CPAP use) groups in reducing the risk of gestational hypertension (RR, 0.65; 95% CI, 0.47-0.89; P = .008) and preeclampsia (RR, 0.70; 95% CI, 0.50-0.98; P = .04). Meta-regression revealed that patients' age (coefficient, -0.0190; P = .83) and BMI (coefficient, -0.0042; P = .87) were not correlated with reduction of risk of hypertension and preeclampsia. Conclusions and Relevance: These findings suggest that implementing CPAP treatment in pregnant women with OSA may reduce the risk of gestational hypertension and preeclampsia.

Tape-assisted fabrication method for constructing PDMS membrane-containing culture devices with cyclic radial stretching stimulation.

Advanced in vitro culture systems have emerged as alternatives to animal testing and traditional cell culture methods in biomedical research. Polydimethylsiloxane (PDMS) is frequently used in creating sophisticated culture devices owing to its elastomeric properties, which allow mechanical stretching to simulate physiological movements in cell experiments. We introduce a straightforward method that uses three types of commercial tape-generic, magic and masking-to fabricate PDMS membranes with microscale thicknesses (47.2 µm for generic, 58.1 µm for magic and 89.37 µm for masking) in these devices. These membranes are shaped as the bases of culture wells and can perform cyclic radial movements controlled via a vacuum system. In experiments with A549 cells under three mechanical stimulation conditions, we analysed transcriptional regulators responsive to external mechanical stimuli. Results indicated increased nuclear yes-associated protein (YAP) and transcriptional coactivator with PDZ-binding motif (TAZ) activity in both confluent and densely packed cells under cyclically mechanical strains (Pearson's coefficient (PC) of 0.59 in confluent and 0.24 in dense cells) compared with static (PC = 0.47 in confluent and 0.13 in dense) and stretched conditions (PC = 0.55 in confluent and 0.20 in dense). This technique offers laboratories without microfabrication capabilities a viable option for exploring cellular behaviour under dynamic mechanical stimulation using PDMS membrane-equipped devices.

Comparative safety of oral Janus kinase inhibitors versus dupilumab in patients with atopic dermatitis: A population-based cohort study.

BACKGROUND: Systemic Janus kinase inhibitors (JAKi) and dupilumab both have emerged as promising therapeutics for atopic dermatitis (AD). Dupilumab has a favorable safety profile, but oral JAKi therapy has been established in other diseases that carry potential comorbid susceptibilities that influence safety. OBJECTIVE: We sought to provide real-world evidence of the comparative safety of oral JAKi versus dupilumab in patients with AD. METHODS: The study used observational data from multiple healthcare organizations in the US. Patients with AD treated with either oral JAKi (upadacitinib, abrocitinib, and baricitinib) or dupilumab were enrolled. The 2 treatment groups were propensity score matched 1:1 on the basis of demographics, comorbidities, and prior medications. Safety outcomes within 2 years after the initiation of medications were measured by hazard ratios (HRs) with 95% confidence intervals (CIs). RESULTS: A total of 14,716 patients were included, with 942 patients treated with oral JAKi and 13,774 with dupilumab. The 2 treatment groups respectively included 938 patients after matching. Treatment with oral JAKi was not associated with increased risks of mortality, malignancies, major adverse cardiovascular events, venous thromboembolism, renal events, or serious gastrointestinal events. However, patients receiving oral JAKi showed significantly higher risks of skin and subcutaneous tissue infection (HR = 1.35, 95% CI = 1.07-1.69), herpes infection (herpes simplex, HR = 1.64, 95% CI = 1.03-2.61; herpes zoster, HR = 2.51, 95% CI = 1.14-5.52), acne (HR = 2.09, 95% CI = 1.54-2.84), cytopenia (anemia, HR = 1.83, 95% CI = 1.39-2.41; neutropenia, HR = 4.02, 95% CI = 1.91-8.47; thrombocytopenia, HR = 1.76, 95% CI = 1.08-2.89), and hyperlipidemia (HR = 1.45, 95% CI = 1.09-1.92); the risk of ophthalmic complications was higher in those receiving dupilumab (HR = 1.49, 95% CI = 1.03-2.17). CONCLUSION: Oral JAKi did not exhibit concerning safety issues in treating patients with AD but increased the risk of infections and abnormalities in laboratory findings. Long-term follow-up data are required to validate these results.

Evaluation of dupilumab on the disease burden in children and adolescents with atopic dermatitis: A population-based cohort study.

BACKGROUND: Dupilumab is the first and only biologic agent approved for the treatment of atopic dermatitis (AD) in pediatric patients aged from 6 months to 17 years. The study aimed to evaluate the impact of dupilumab on the occurrence of comorbidities in pediatric patients with AD. METHODS: In this population-based cohort study, we utilized electronic health records from multiple healthcare organizations across the United States. Pediatric patients (<18 years of age) with a diagnosis of AD initiating dupilumab were propensity-score matched 1:1 to those initiating other systemic agents (azathioprine, cyclosporine, methotrexate, mycophenolate mofetil, or systemic corticosteroids). The primary outcomes were new-onset comorbidities emerging during the study period measured by the risk ratio (RR) and its confidence interval (CI). Subgroup analyses were stratified by age (0-5 years, 6-11 years, and 12-17 years), sex, and race. RESULTS: A total of 3575 pediatric patients with AD treated with dupilumab were matched to 3575 patients treated with other systemic agents. The dupilumab cohort was associated with a lowered risk of new-onset atopic comorbidities (including asthma [RR, 0.72; 95% CI, 0.59-0.89] and allergic rhinitis [RR, 0.62; 95% CI, 0.52-0.74]), infections (e.g., skin and soft tissue infection [RR, 0.70; 95% CI, 0.63-0.76] and respiratory tract infection [RR = 0.56; 95% CI, 0.51-0.61]), psychiatric disorders (e.g., mood disorder [RR, 0.52; 95% CI, 0.39-0.70] and anxiety [RR, 0.57; 95% CI, 0.46-0.70], sleep disturbance [RR, 0.60; 95% CI, 0.47-0.77]), neurologic and developmental disorders (e.g., attention deficit hyperactivity disorder [RR, 0.54; 95% CI, 0.38-0.75]). Furthermore, the positive effects are found to be more pronounced in younger children (aged 0-5 years) with AD. CONCLUSIONS: Treatment with dupilumab compared to systemic agents resulted in reductions in AD-related comorbidities in pediatric patients.

The Effectiveness of Palliative Care Interventions in Long-Term Care Facilities: A Systematic Review.

The increasing elderly population is driving higher utilization rates of long-term care facilities, where residents often have multiple chronic diseases, making them potential candidates for palliative care. Timely palliative care interventions can improve their quality of life and medical autonomy. This study systematically reviews the effectiveness of palliative care programs in long-term care facilities. Databases such as PubMed, EMBASE, Cochrane Library, and Airiti Library were searched up to 31 December 2023, using PICO criteria and the following keywords: 'care home', 'nursing home', 'residential aged care facility', and 'long-term care facility' for patients; and 'Gold Standard Framework in Care Homes', 'integrated care pathway', 'care home project', and 'palliative care program' for interventions. Seven articles were included. The results indicate that the Program of All-Inclusive Care for the Elderly (PACE) intervention did not significantly influence overall quality of life but did improve the quality of death. There were no statistical differences in comfort or quality of death between the dementia and non-dementia groups. However, PACE significantly reduced healthcare costs. The implementation of the Liverpool Care Pathway (LCP) notably enhanced the control of terminal symptoms, while the Gold Standard Framework in Care Homes (GSFCH) effectively improved end-of-life care rates, do-not-resuscitate (DNR) signing rates, advance care planning (ACP) completion rates, and reduced inappropriate readmission rates. While palliative care interventions are shown to improve the quality of end-of-life care, their practical application should be adapted to fit the implementation conditions and capabilities of domestic long-term care facilities.

[Quality control method for phenolic acid components in abandoned stems and leaves of Artemisia selengensis based on UPLC fingerprint combined with quantitative analysis of multi-components by single marker (QAMS)].

This study established an ultra-performance liquid chromatography(UPLC) fingerprint of abandoned stems and leaves of Artemisia selengensis and quantitative analysis of multi-components by single marker(QAMS) for five phenolic acid components. Waters Acquity UPLC BEH C_(18) chromatography column(2.1 mm×100 mm, 1.7 µm) was used. The gradient elution was carried out with the mobile phase composed of 0.1% phosphoric acid water and acetonitrile at a flow rate of 0.3 mL·min~(-1) and a column temperature at 30 ℃. The detection wavelength was 330 nm, and the injection volume was 2 µL. Similarity evaluation and cluster analysis were conducted on the fingerprint data, and 15 common components in 13 batches of abandoned stems and leaves of A. selengensis were identified. The relative correction factors of ferulic acid, isochlorogenic acid A, isochlorogenic acid B, and isochlorogenic acid C were calculated using chlorogenic acid as the internal reference. The QAMS for determining five components in the abandoned stems and leaves of A. selengensis was established. At the same time, the content of these five components was determined using the external standard method(ESM), and the results showed that there were no significant differences in their content determined by the QAMS and the ESM. The results indicated that the content of phenolic acid components in the abandoned stems and leaves of A. selengensis from different varieties and different origins had obvious differences. In addition, the content of phenolic acid components in the abandoned stems and leaves of lignified A. selengensis was significantly higher than that of non-lignified A. selengensis. In summary, QAMS established in this study can be quickly, accurately, and economically used to determine the content of five phenolic acid components in abandoned stems and leaves of A. selengensis, laying a foundation for the resource development and utilization of abandoned stems and leaves of A. selengensis.

Improved prediction of anti-angiogenic peptides based on machine learning models and comprehensive features from peptide sequences.

Angiogenesis is a key process for the proliferation and metastatic spread of cancer cells. Anti-angiogenic peptides (AAPs), with the capability of inhibiting angiogenesis, are promising candidates in cancer treatment. We propose AAPL, a sequence-based predictor to identify AAPs with machine learning models of improved prediction accuracy. Each peptide sequence was transformed to a vector of 4335 numeric values according to 58 different feature types, followed by a heuristic algorithm for feature selection. Next, the hyperparameters of six machine learning models were optimized with respect to the feature subset. We considered two datasets, one with entire peptide sequences and the other with 15 amino acids from peptide N-termini. AAPL achieved Matthew's correlation coefficients of 0.671 and 0.756 for independent tests based on the two datasets, respectively, outperforming existing predictors by a range of 5.3% to 24.6%. Further analyses show that AAPL yields higher prediction accuracy for peptides with more hydrophobic residues, and fewer hydrophilic and charged residues. The source code of AAPL is available at https://github.com/yunzheng2002/Anti-angiogenic .

pLxIS-containing domains are biochemically flexible regulators of interferons and metabolism.

Signal transduction proteins containing a pLxIS motif induce interferon (IFN) responses central to antiviral immunity. Apart from their established roles in activating the IFN regulator factor (IRF) transcription factors, the existence of additional pathways and functions associated with the pLxIS motif is unknown. Using a synthetic biology-based platform, we identified two orphan pLxIS-containing proteins that stimulate IFN responses independent of all known pattern-recognition receptor pathways. We further uncovered a diversity of pLxIS signaling mechanisms, where the pLxIS motif represents one component of a multi-motif signaling entity, which has variable functions in activating IRF3, the TRAF6 ubiquitin ligase, IκB kinases, mitogen-activated protein kinases, and metabolic activities. The most diverse pLxIS signaling mechanisms were associated with the highest antiviral activities in human cells. The flexibility of domains that regulate IFN signaling may explain their prevalence in nature.
