Nonetheless, intense efficacy for in vivo treatment is restricted by inadequate photocatalytic activity and visible light response.Methods: In this study, we designed a photocatalytic heterostructure using graphitic carbon nitride (g-C3N4) and tin disulfide (SnS2) to synthesize g-C3N4/SnS2 heterostructure through hydrothermal process. Furthermore, Au nanoparticles were decorated in situ deposition on the surface of the g-C3N4/SnS2 heterostructure to form g-C3N4/SnS2@Au nanoparticles.Results: The g-C3N4/SnS2@Au nanoparticles generated intense reactive oxygen species radicals under near-infrared (NIR) laser irradiation through photodynamic therapy (PDT) pathways (Type-I and Type-II). These nanoparticles exhibited enhanced photothermal therapy (PTT) efficacy with high photothermal conversion efficiency (41%) when subjected to 808 nm laser light, owing to the presence of Au nanoparticles. The in vitro studies have indicated that these nanoparticles can induce human liver carcinoma cancer cell (HepG2) apoptosis (approximately 80% cell death) through the synergistic therapeutic effects of PDT and PTT. The in vivo results demonstrated that these nanoparticles exhibited enhanced efficient antitumor effects based on the combined effects of PDT and PTT.Conclusion: The g-C3N4/SnS2@Au nanoparticles possessed enhanced photothermal properties and PDT effect, good biocompatibility and intense antitumor efficacy. Therefore, these nanoparticles could be considered promising candidates through synergistic PDT/PTT effects upon irradiation with NIR laser for cancer treatment.Keywords: g-C3N4, SnS2, Gold nanoparticles, Photodynamic therapy, Photothermal therapy

Hospital administrators can encourage healthcare staff to voluntarily examine the potential occurrence and severity of risks, thereby enhancing awareness of patient safety. The purpose of this study is to explore the effects of huddle intervention on patient safety culture among medical team members and related factors.Methods: We used a one-group pretest-posttest research design and convenience sampled 109 members of the general internal medicine ward team members from a medical center in central Taiwan. They participated 2 times per week in 15-min huddles from 08:15 to 08:30 in the morning, which lasted for a total of 4 weeks. The process was based on submitted ideas, approved ideas, research ideas and standardization, and data on the safety attitudes questionnaire (SAQ) were collected during the huddles’ intervention pretest and posttest.Results: After the huddle intervention, we found significantly improved scores for safety attitude, teamwork climate (76.49± 16.13 vs 83.26± 13.39, p < 0.001), safety climate (75.07± 16.07 vs 82.63± 13.72, p < 0.001), job satisfaction (73.67± 19.84 vs 83.39± 17.21, p < 0.001), perceptions of management (77.87± 19.99 vs 84.86± 16.03, p < 0.001) and working conditions (78.96± 18.16 vs 86.18± 14.90, p < 0.001). Correlation analyses on the differences between pretest and posttest showed that age had a significant correlation with safety climate (r = 0.22, p = 0.022) and working conditions (r = 0.20, p = 0.035). The number of times to participate in a huddle had a significant correlation with teamwork climate (r = 0.33, p =< .001), safety climate (r = 0.30, p = 0.002), job satisfaction (r = 0.19, p = 0.043), and work conditions (r = 0.28, p = 0.003).Conclusion: Huddles improve clinical team members’ understanding of different dimensions and relate factors of safety attitudes. Implementation of the huddles involved standardized process will help hospital administrators understand the steps to parallel expansion to other wards.Keywords: huddle, patient safety, patient care team

Study characteristics, ethnicity, vaccine types, dose intervals, and SARS-CoV-2 infection prevalence may influence the rates of myocarditis and pericarditis after mRNA vaccination in population-based studies.Methods: We comprehensively searched MEDLINE for relevant articles published before November 30, 2022. We also searched the websites of health authorities in several countries for unpublished surveillance data on myocarditis and pericarditis after mRNA vaccination. The outcome of interest was the incidence of myocarditis and pericarditis developed after mRNA vaccination for COVID-19.Results: A total of 17 studies form 10 countries were included for review. We noted that considerable heterogeneity in study characteristics, including surveillance method, case definition, and observation period, may partially be responsible for the widely varied reported rates. Studies from countries that adopted active surveillance reported higher rates than those using passive surveillance. Compared to BNT162b2 vaccine, mRNA-1273 may have a higher risk of myocarditis only in young men after the second dose. Our comparison of sex-, age-, vaccine type-, and dose-specific rates of myocarditis across countries did not support the hypothesis that individuals with recent SARS-CoV-2 infection and young Asian males were at higher risk. We also could not find sufficient evidence to conclude whether extending the between-dose interval could reduce myocarditis incidence following mRNA vaccination.Conclusion: Differences in the study characteristics must be fully considered when comparing the risks of mRNA vaccine-related myocarditis and pericarditis in different countries.Keywords: COVID-19, mRNA vaccine, myocarditis, population-based study, surveillance data

However, patients with COPD may not be always adhere to the prescribed inhaled medications. Therefore, understanding the underlying reasons for patients with COPD adhering to inhaled medications is important. The present study used Theory of Planned Behavior (TPB) as a theoretical framework to develop the Intention of Inhaled Medication Adherence Scale (IMAS) and assess its psychometric properties.Patients and Methods: After reviewing papers using the TPB to design psychometric scales and the TPB scale development guidelines, 28 items were generated for expert evaluation. Eight experts reported that the 28 items all had good content validity (content validity index ranged from 0.88 to 1.00 at item-level; and from 0.981 to 0.987 at scale-level) comprising four factors. Following initial development, 235 patients with COPD (mean age 73.12 years; 93.6% males) completed the IMAS via interview with a respiratory therapist and a research assistant. The four-factor structure of the IMAS was evaluated using confirmatory factor analysis (CFA).Results: Nine IMAS items were removed because of low factor loadings or offending estimates. The 19-item IMAS was confirmed as having a four-factor structure supported by the CFA results (comparative fit index=1.00; Tucker-Lewis index=1.00; root mean square error of approximation=0.00; standardized root mean square residual=0.06).Conclusion: The 19-item IMAS had satisfactory psychometric properties in construct validity. The 19-item IMAS is an instrument that could help healthcare providers understand potential factors associated with adherence to inhaled medications among people with COPD.Keywords: adherence, confirmatory factor analysis, COPD, psychometrics

The inability of caregivers to perceive their own emotions affects their responses to children. This study aims to examine the relationship between a mother’s difficulties in emotional expression and children’s emotional and behavioral disorders.Patient and Methods: A total of 78 cases, aged between 3 and 15 years old, were included in this study. The mothers completed the Taiwan version of the “Toronto Alexithymia Scale” (TAS) and “Children’s Behavior Checklist” (CBCL) questionnaires, which served as research tools. TAS consists of three factors: difficulty in distinguishing emotions (Factor 1, F1), difficulty in expressing feelings (Factor 2, F2), and an externally oriented thinking style (Factor 3, F3). CBCL represents a child’s behavior profile. The Mann–Whitney test and correlation analyses were used for follow-up analysis.Results: Our analysis revealed that F1, F2, F3, and total scores of TAS (TAS-Total) correlate positively with the somatic complaint subscale of CBCL (F1: p = 0.003; F2: p = 0.002; F3: p = 0.034, TAS-Total p=0.002). Additionally, TAS-F1 was positively correlated with the internalizing problems subscale of CBCL (p = 0.020) and the withdrawn (WD) subscale of CBCL (p = 0.044). We also found a significant association between TAS-F1 and WD of CBCL in boys alone (p = 0.022). However, we observed a negative association between TAS-F3 and the social problems subscale of CBCL in boys alone (p = 0.038).Conclusion: Mothers with alexithymic features are more likely to have children who internalize emotions, leading to withdrawal and somatic expression. Boys tend to exhibit withdrawal traits associated with internalization. This study provides initial evidence of a partial correlation between maternal alexithymia and children’s emotional and behavioral disorders, emphasizing the importance of investigating caregivers’ emotional traits for a better understanding of children’s development in the future.Keywords: maternal alexithymia, childhood behavioral disturbance, external and internal problem, children’s behavior checklist, Toronto alexithymia scale

Nonlinear wave mixing in solids with ultrafast x-rays can provide insight into complex electronic dynamics of materials. Here, tabletop-based attosecond noncollinear four-wave mixing (FWM) spectroscopy using one extreme ultraviolet (XUV) pulse from high harmonic generation and two separately timed few-cycle near-infrared (NIR) pulses characterizes the dynamics of the Na+ L2,3 edge core-excitons in NaCl around 33.5 eV. An inhomogeneous distribution of core-excitons underlying the well-known doublet absorption of the Na+ Γ point core-exciton spectrum is deconvoluted by the resonance-enhanced nonlinear wave mixing spectroscopy. In addition, other dark excitonic states that are coupled to the XUV-allowed levels by the NIR pulses are characterized spectrally and temporally. Approximately

Descriptive statistics were calculated to compare the two TSCS datasets. Then, multiple regression models were constructed with health outcome as the dependent variable, and demographics and other key components as independent variables.Results: The 2011 TSCS cohort showed higher prevalence for cigarette smoking (30.8% vs 25.2%; p=0.002), alcohol drinking (52.5% vs 24.3%; p< 0.001), exercise habits (52.7% vs 48.0%; p=0.02), and better fruit and vegetable accessibility (Mean=3.91 vs 3.82; p=0.04). The 2021 TSCS cohort reported higher body mass index (Mean=24.20 vs 23.63; p< 0.001), less residency in urban areas (22.4% vs 31.1%; p< 0.001), better jogging accessibility (4.14 vs 4.05; p=0.006), higher generalized trust (2.26 vs 2.17; p=0.001), and greater internet usage (3.43 vs 2.89; p< 0.001). The regression model showed that exercise habits (standardized coefficient=0.20 and 0.10; p< 0.001) and generalized trust (standardized coefficient=0.11 and 0.11; p=0.004 and < 0.001) were consistently associated with health outcomes in both cohorts. Additionally, internet use (standardized coefficient=− 0.07; p=0.026) and alcohol drinking behaviors (standardized coefficient=− 0.07; p=0.0022) were negatively associated with health outcomes in the 2021 cohort.Conclusion: The present study demonstrated the trends and changes over 10 years regarding multiple health-related components among Taiwan residents. The study’s findings provide insight into education promotion programs to reduce unhealthy behaviors as well as enhancing generalized trust building and developing healthy behaviors for Taiwan residents.Keywords: health behavior, health promotion, COVID-19, Taiwan, trust

This work reports a precise measurement of the reactor antineutrino flux using 2.2 million inverse beta decay (IBD) events collected with the Daya Bay near detectors in 1230 days. The dominant uncertainty on the neutron detection efficiency is reduced by 56% with respect to the previous measurement through a comprehensive neutron calibration and detailed data and simulation analysis. The new average IBD yield is determined to be (5.91±0.09)×10-43 cm2/fission with total uncertainty improved by 29%. The corresponding mean fission fractions from the four main fission isotopes U235, U238, Pu239, and Pu241 are 0.564, 0.076, 0.304, and 0.056, respectively. The ratio of measured to predicted antineutrino yield is found to be 0.952±0.014±0.023 (1.001±0.015±0.027) for the Huber-Mueller (ILL-Vogel) model, where the first and second uncertainty are experimental and theoretical model uncertainty, respectively. This measurement confirms the discrepancy between the world average of reactor antineutrino flux and the Huber-Mueller model.

Scanning tunneling microscopy (STM) at 5 K is used to study WSe2 layers grown on epitaxial graphene which is formed on Si-terminated SiC(0 0 0 1). Specifically, a partial hydrogenation process is applied to intercalate hydrogen at the SiC-graphene interface, yielding areas of quasi-free-standing bilayer graphene coexisting with bare monolayer graphene. We find that an abrupt and structurally perfect homojunction (band-edge offset ∼0.25 eV) is formed when WSe2 overgrows a lateral junction between adjacent monolayer and quasi-free-standing bilayer areas in the graphene. The band structure modulation in the WSe2 overlayer arises from the varying work function (electrostatic potential) of the graphene beneath. Scanning tunneling spectroscopy measurements reveal that this effect can be also utilized to create WSe2 quantum dots that confine either valence or conduction band states, in agreement with first-principles band structure calculations.

This study aimed to assess whether prenatal/postnatal exposure to ambient air pollutants is related to the development of asthma in infants with NJ.Patients and Methods: A nested case–control retrospective study was performed using the data of infants with NJ in the Kaohsiung Medical University Hospital Research Database. Data on average ambient air pollution concentrations within six months, the first year and second year after birth, and in the first, second and third prenatal trimesters were collected. NJ was defined as TSB levels ≥ 2 mg/dl with the diagnosis less than one-month-old. Asthma was defined as a diagnosis with medication use. We constructed conditional logistic regression models to estimate adjusted odds ratios (aORs) and 95% confidence intervals (CIs).Results: Exposure to NO and SO2 at all six time points in the study was significantly associated with an increased risk of preschool asthma in infants with NJ. The overall peak OR (95% CI) of SO2, PM2.5, PM10, NO, NO2, and NOX were 1.277 (1.129– 1.444), 1.057 (1.023– 1.092), 1.035 (1.011– 1.059), 1.272 (1.111– 1.455), 1.168 (1.083– 1.259) and 1.104 (1.051– 1.161), respectively. Fetuses in the first and second trimester were most vulnerable to ambient air pollutant exposure such as SO2 PM2.5, NO, NO2 and NOX during the prenatal period. Exposure to all six ambient air pollutants during the first and second years after birth significantly affected preschool asthma in NJ infants.Conclusion: In different time windows, prenatal and postnatal exposure to SO2, PM2.5, PM10, NO, NO2, and NOX were associated with preschool asthma in NJ infants. The relatively high impact of NO and SO2 exposure in infants with NJ requires further studies and prevention measures.Keywords: 1000 days, air pollution, SO2, neonatal hyperbilirubinemia, asthma

A search for a time-varying νe signal was performed with 621 days of data acquired by the Daya Bay Reactor Neutrino Experiment over 704 calendar days. The time spectrum of the measured νe flux normalized to its prediction was analyzed with a Lomb-Scargle periodogram, which yielded no significant signal for periods ranging from 2 hours to nearly 2 years. The normalized time spectrum was also fit for a sidereal modulation under the Standard Model Extension (SME) framework to search for Lorentz and CPT violation (LV-CPTV). Limits were obtained for all six flavor pairs ēμ,ēτ, μτ, ēē,μμ and ττ by fitting them one at a time, constituting the first experimental constraints on the latter three. Daya Bay's high statistics and unique layout of multiple directions from three pairs of reactors to three experimental halls allowed the simultaneous constraint of individual SME LV-CPTV coefficients without assuming others contribute negligibly, a first for a neutrino experiment.

Neutrons produced by cosmic ray muons are an important background for underground experiments studying neutrino oscillations, neutrinoless double beta decay, dark matter, and other rare-event signals. A measurement of the neutron yield in the three different experimental halls of the Daya Bay Reactor Neutrino Experiment at varying depth is reported. The neutron yield in Daya Bay's liquid scintillator is measured to be Yn=(10.26±0.86)×10-5, (10.22±0.87)×10-5, and (17.03±1.22)×10-5 μ-1 g-1 cm2 at depths of 250, 265, and 860 meters-water-equivalent. These results are compared to other measurements and the simulated neutron yield in Fluka and Geant4. A global fit including the Daya Bay measurements yields a power law coefficient of 0.77±0.03 for the dependence of the neutron yield on muon energy.

The Daya Bay Experiment consists of eight identically designed detectors located in three underground experimental halls named as EH1, EH2, EH3, with 250, 265 and 860 meters of water equivalent vertical overburden, respectively. Cosmic muon events have been recorded over a two-year period. The underground muon rate is observed to be positively correlated with the effective atmospheric temperature and to follow a seasonal modulation pattern. The correlation coefficient α, describing how a variation in the muon rate relates to a variation in the effective atmospheric temperature, is found to be αEH1 = 0.362±0.031, αEH2 = 0.433±0.038 and αEH3 = 0.641±0.057 for each experimental hall.

Macrophages are heterogeneous with divergent M1/M2 polarization phenotypes in response to various stimulations during the inflammatory process. We aimed to investigate the pattern of macrophage polarization and its association with severity and exacerbation in asthmatic children.Patients and Methods: Normal and asthmatic children aged 4– 18 years were enrolled for 12 months. Children with asthma were further subgrouped according to their severity and the requirement for hospitalization during exacerbations. Clinical data were obtained from medical records. Peripheral blood samples were collected to analyze macrophage polarization, including M1, M2, and subsets, by flow cytometry.Results: Fifty-one asthmatic cases and 27 normal controls were included in this study. The level of PM-2K+CD14+ but not PM-2K+CD14− was decreased in asthmatic children. The levels of M2a (CCR7−CXCR1+), M2b (CCR7−CD86+), and M2c (CCR7−CCR2+) subsets, but not M1 (CCR7+CD86+), were increased in asthmatic children. The levels of M1 were decreased, but the levels of M2c were increased, in children with moderate asthma compared to those with mild asthma. The levels of PM-2K+CD14+ cells and M1 subsets were decreased, but the M2c subset cells were increased in asthmatic children requiring hospitalization during exacerbations.Conclusion: Macrophage polarization may be involved in the pathogenesis of childhood asthma and is a potential biomarker of childhood asthma disease severity.Keywords: M2 macrophage polarization, asthma severity, asthma exacerbation, childhood asthma hospitalization

Bonner Spheres have been used widely for the measurement of neutron spectra with neutron energies ranged from thermal up to at least 20 MeV . A Bonner Sphere neutron spectrometer (BSS) was developed by extending a Berthold LB 6411 neutron-dose-rate meter. The BSS consists of a 3He thermal-neutron detector with integrated electronics, a set of eight polyethylene spherical shells and two optional lead shells of various sizes. The response matrix of the BSS was calculated with GEANT4 Monte Carlo simulation. The BSS had a calibration uncertainty of ± 8.6% and a detector background rate of (1.57 ± 0.04) × 10-3 s-1. A spectral unfolding code NSUGA was developed. The NSUGA code utilizes genetic algorithms and has been shown to perform well in the absence of a priori information.

We have measured the muon flux and production rate of muon-induced neutrons at a depth of 611 m water equivalent. Our apparatus comprises three layers of crossed plastic scintillator hodoscopes for tracking the incident cosmic-ray muons and 760 L of a gadolinium-doped liquid scintillator for producing and detecting neutrons. The vertical muon intensity was measured to be Iμ=(5.7±0.6)×10-6 cm-2 s-1 sr-1. The yield of muon-induced neutrons in the liquid scintillator was determined to be Yn=(1.19±0.08(stat)±0.21(syst))×10-4 neutrons/(μ·g·cm-2). A fit to the recently measured neutron yields at different depths gave a mean muon energy dependence of 0.76±0.03 for liquid-scintillator targets.

We developed a highly sensitive, reliable and portable automatic system (H3) to monitor the radon concentration of the underground experimental halls of the Daya Bay Reactor Neutrino Experiment. H3 is able to measure radon concentration with a statistical error less than 10% in a 1-h measurement of dehumidified air (R.H. 5% at 25°C) with radon concentration as low as 50 Bq/m3. This is achieved by using a large radon progeny collection chamber, semiconductor α-particle detector with high energy resolution, improved electronics and software. The integrated radon monitoring system is highly customizable to operate in different run modes at scheduled times and can be controlled remotely to sample radon in ambient air or in water from the water pools where the antineutrino detectors are being housed. The radon monitoring system has been running in the three experimental halls of the Daya Bay Reactor Neutrino Experiment since November 2013.

However, the clinical significance of DHEA and DHEAS concentrations in patients with NSCLC receiving chemotherapy (CT) has not been sufficiently documented.Objective: To evaluate the correlation between mental health and hormone concentrations on patients with advanced non-small-cell lung cancer (NSCLC).Materials and Methods: The present study was a cross-sectional analysis based on a self-reported psychological investigation. Salivary samples were collected from 22 patients with advanced NSCLC after CT and 17 healthy controls. The concentrations of DHEA, DHEAS, and cortisol were analyzed to investigate their associations with the results of self-reported questionnaires on psychological health.Results: Patients with advanced NSCLC exhibited significantly higher Patient Health Questionnaire (PHQ-9) and Startle, Physiological arousal, Anger, and Numbness-Chinese version (SPAN-C) scores, poorer health conditions, lower sleep quality, and more severe fatigue after CT than did healthy controls, and salivary concentrations of DHEA and DHEAS were significantly lower among patients after CT than among controls. DHEAS concentrations were negatively associated with depression scores (PHQ-9, r = − 0.496, P = 0.019) and fatigue scores (Brief Fatigue Inventory-Taiwan, r = − 0.562, P = 0.006).Conclusion: Patients with advanced NSCLC after CT had lower DHEA and DHEAS concentrations than did controls. Lower DHEAS concentrations were associated with higher fatigue and depression scores.Keywords: cancer-related fatigue, chemotherapy, DHEA, DHEAS, lung cancer

NRF2 has recently been proposed as a novel target for cancer chemoprevention. The fungicide miconazole has shown promising antiproliferative effects in cancer cells.Materials and Methods: After miconazole treatment, the p62-KEAP1-NRF2 activation was analyzed by qPCR and Western blot. The nuclear translocation indicating NRF2 activation was further confirmed by immunofluorescence. Finally, the ROS production was detected by CM-H2DCFDA staining.Results: We demonstrate in this study that miconazole dramatically increases NRF2 activation in bladder cancer cells, in a dose- and time-dependent manner. Interestingly, levels of expression of p62, a noncanonical pathway that mediates NRF2 activation, appeared to increase in accordance with NRF2. We also investigated levels of the negative regulator kelch-like ECH-associated protein 1 (KEAP1), which is involved in NRF2 activation. As expected, a decrease in KEAP1 expression was found after miconazole exposure. Confirmation of NRF2 nuclear translocation was monitored by immunofluorescence. Miconazole-induced generation of reactive oxygen species (ROS) promoted NRF2 activation. Pretreatment of bladder cancer cells with ROS scavengers abolished NRF2 expression and nuclear translocation, indicating that miconazole activates the noncanonical p62-KEAP1-NRF2 pathway, which is regulated by ROS production.Conclusion: Our study elucidates the mechanisms through which miconazole stimulates NRF2 which may contribute to cancer chemopreventive effects.Keywords: miconazole, NRF2, p62, KEAP1, bladder cancer

Clinically, the adverse effect of PPIs on patients with non-small cell lung cancer (NSCLC) treated with first-line EGFR TKIs remains controversial. This study was conducted to evaluate whether the combined use of gefitinib with PPIs affected NSCLC outcomes.Patients and methods: We performed a nationwide cohort study of patients newly diagnosed with NSCLC between 1997 and 2013 using the Taiwan Cancer Registry and Taiwan National Health Insurance databases. We identified patients who were treated with first-line EGFR TKIs and analyzed the association between use of PPIs and TKI treatment outcome. We defined the coverage ratio of PPIs as duration of PPI treatment in days divided by duration of TKIs in days. Patients who exhibited an overlap of >20% between PPI and TKI usage days were defined as having a high coverage ratio.Results: A total of 1278 patients were treated with first-line gefitinib, 309 of which took PPIs at the same time and 145 had a high PPI coverage ratio. Patients had similar time to failure regardless of their PPI coverage ratio during gefitinib treatment. However, higher PPI coverage ratio significantly decreased overall survival (OS) compared with that of patients with a lower PPI coverage ratio or no PPI treatment in univariate analysis (median OS, 13.5, 16.7, and 21.8 months, respectively, p

HIV-infected patients were screened for HCV antibody since June 1, 2012, and HCV and HIV co-infected patients were tested for HCV RNA. The subjects who experienced PegIFN/RBV were enrolled in the study, and of whom with chronic genotype 1a or 1b received grazoprevir 100 mg and elbasvir 50 mg in a fixed-dose combination tablet once daily with or without ribavirin for 12 to 16 weeks.Results: Of 2,419 HIV-infected patients, 40 patients with chronic genotype 1 HCV and HIV co-infection who failed PegIFN/RBV treatment were enrolled. Sixteen patients had genotype 1a and 24 patients had genotype 1b, with or without cirrhosis. The median age was 42 (41–47) years, and 5 patients (12.5%) were diagnosed with liver cirrhosis (child Pugh score A). The median CD4 count was 504 cells/μL (321–689). All patients (100%) had HIV viral load 10 IU/mL (3.98–7.12). At the end of treatment, all patients (100%, 40/40) had undetectable HCV viral load, and 95.0% (38/40) of patients achieved sustained virologic response at 12 weeks.Conclusion: Grazoprevir/elbasvir was effective in genotype 1 patients co-infected with HIV with or without cirrhosis. This finding is consistent with that of previous trials of this regimen in monoinfected population.Keywords: hepatitis C, grazoprevir and elbasvir, PEGylated interferon plus ribavirin, direct-acting antiviral, HCV genotype 1, HCV/HIV co-infection

Yai-Ping Hsiao,1 Chung-Hsiung Huang,2 Yu-Chin Lin,3 Tong-Rong Jan1 1Department and Graduate Institute of Veterinary Medicine, School of Veterinary Medicine, National Taiwan University, Taipei, Taiwan; 2Department of Food Science, National Taiwan Ocean University, Keelung, Taiwan; 3Department of Medicinal Botanicals and Health Applications, College of Biotechnology & Bioresources, Da-Yeh University, Changhua, Taiwan Background: Medicinal preparations of iron oxide nanoparticles (IONPs) have been used as MRI contrast agents for the diagnosis of hepatic tumors and the assessment of neuroinflammation and blood–brain barrier integrity. However, it remains mostly unclear whether exposure to IONPs affects neuroinflammation under disease conditions. The present study aims to investigate the impact of IONPs on autoimmune-mediated neuroinflammation using a murine model of experimental autoimmune encephalomyelitis (EAE) that mimics human multiple sclerosis.Methods: Mice were either left untreated or immunized with myelin oligodendrocyte glycoprotein on day 0 followed by two injections of pertussis toxin for EAE induction. The EAE mice were intravenously administered with a single dose of the carboxydextran-coated IONPs, ferucarbotran (20 mg Fe/kg) and/or saline (as vehicle) on day 18. Symptoms of EAE were daily monitored until the mice were killed on day 30. Tissue sections of the brain and spinal cord were prepared for histopathological examinations. Iron deposition, neuron demyelination and inflammatory cell infiltration were examined using histochemical staining. The infiltration of microglial and T cells, and cytokine expression were examined by immunohistochemical staining and/or reverse transcription polymerase chain reaction (RT-PCR).Results: Iron deposition was detected in both the brain and spinal cord of EAE mice 3 days post-ferucarbotran treatment. The clinical and pathological scores of EAE, percentage of myelin loss and infiltration of inflammatory cells into the spinal cord were significantly deteriorated in EAE mice treated with ferucarbotran. Furthermore, ferucarbotran treatment increased the number of CD3+, Iba-1+, IL-6+, Iba-1+TNF-α+ and CD3+IFN-γ+ cells in the spinal cord of EAE mice.Conclusion: A single exposure to ferucarbotran exacerbated neuroinflammation and disease severity of EAE, which might be attributed to the enhanced activation of microglia and T cells. These results demonstrated that the pro-inflammatory effect of ferucarbotran on the central nervous system is closely associated with the deterioration of autoimmunity.

Methods: This study aimed to evaluate the effect of mindful sport performance enhancement (MSPE) on mental health, flow state, and competitive state anxiety using a 4-week workshop. We recruited an amateur baseball team (N=21) in Taiwan, and collected information by self-reported questionnaires administered before, immediately after, and at a 4-week follow-up. The primary outcome was to evaluate sports performance by flow state and competitive state anxiety, which included self-confidence, somatic anxiety, and cognitive anxiety. The secondary outcome was to explore whether MSPE intervention can improve anxiety, depression, sleep disturbance, and eating disorders.Result: After the workshop and follow-up 1 month later, we found improvements in flow state (P=0.001; P=0.045), cognitive anxiety in competitive anxiety (P=0.056; P=0.008), global eating disorder (P=0.009; P

To meet this demand, cancer cells drastically upregulate glucose uptake and metabolism compared to normal cells. This difference has made the blocking of glycolysis a fascinating strategy to treat this malignant disease. α-enolase is not only one of the most upregulated glycolytic enzymes in cancer cells, but also associates with many cellular processes or conditions important to cancer cell survival, such as cell migration, invasion, and hypoxia. Targeting α-enolase could simultaneously disturb cancer cells in multiple ways and, therefore, is a good target for anticancer drug development. In the current study, more than 22 million chemical structures meeting the criteria of Lipinski’s rule of five from the ZINC database were docked to α-enolase by virtual screening. Twenty-four chemical structures with docking scores better than that of the enolase substrate, 2-phosphoglycerate, were further screened by the absorption, distribution, metabolism, excretion, and toxicity (ADMET) properties prediction. Four of them were classified as non-mutagenic, non-carcinogenic, and capable of oral administration where they showed steady interactions to α-enolase that were comparable, even superior, to the currently available inhibitors in molecular dynamics (MD) simulation. These compounds may be considered promising leads for further development of the α-enolase inhibitors and could help fight cancer metabolically.

Chencai Wang,1 Chao-Hsiung Hsu,1,2 Zhao Li,1 Lian-Pin Hwang,2 Ying-Chih Lin,2 Pi-Tai Chou,2 Yung-Ya Lin1 1Department of Chemistry and Biochemistry, University of California, Los Angeles, CA, USA; 2Department of Chemistry, National Taiwan University, Taipei, Taiwan Abstract: Magnetic resonance (MR) nano-theranostic hyperthermia uses magnetic nanoparticles to target and accumulate at the lesions and generate heat to kill lesion cells directly through hyperthermia or indirectly through thermal activation and control releasing of drugs. Preclinical and translational applications of MR nano-theranostic hyperthermia are currently limited by a few major theoretical difficulties and experimental challenges in in vivo conditions. For example, conventional models for estimating the heat generated and the optimal magnetic nanoparticle sizes for hyperthermia do not accurately reproduce reported in vivo experimental results. In this work, a revised cluster-based model was proposed to predict the specific loss power (SLP) by explicitly considering magnetic nanoparticle aggregation in in vivo conditions. By comparing with the reported experimental results of magnetite Fe3O4 and cobalt ferrite CoFe2O4 magnetic nanoparticles, it is shown that the revised cluster-based model provides a more accurate prediction of the experimental values than the conventional models that assume magnetic nanoparticles act as single units. It also provides a clear physical picture: the aggregation of magnetic nanoparticles increases the cluster magnetic anisotropy while reducing both the cluster domain magnetization and the average magnetic moment, which, in turn, shift the predicted SLP toward a smaller magnetic nanoparticle diameter with lower peak values. As a result, the heating efficiency and the SLP values are decreased. The improvement in the prediction accuracy in in vivo conditions is particularly pronounced when the magnetic nanoparticle diameter is in the range of ~10–20 nm. This happens to be an important size range for MR cancer nano-theranostics, as it exhibits the highest efficacy against both primary and metastatic tumors in vivo. Our studies show that a relatively 20%–25% smaller magnetic nanoparticle diameter should be chosen to reach the maximal heating efficiency in comparison with the optimal size predicted by previous models.

Autophagy induction has been implied to contribute to cisplatin resistance in ovarian cancer; and a high basal level of autophagy has been demonstrated in human bladder tumors. Therefore, it is reasonable to speculate that autophagy may account for the failure of cisplatin single treatment in BC. This study investigated whether cisplatin induces autophagy and the mechanism involved using human BC cell lines.Materials and methods: Human BC cells (5637 and T24) were used in this study. Cell viability was detected using water soluble tetrazolium-8 reagents. Autophagy induction was detected by monitoring the levels of light chain 3 (LC3)-II and p62 by Western blot, LC3-positive puncta formation by immunofluorescence, and direct observation of the autophagolysosome (AL) formation by transmission electron microscopy. Inhibitors including bafilomycin A1 (Baf A1), chloroquine (CQ), and shRNA-based lentivirus against autophagy-related genes (ATG7 and ATG12) were utilized. Apoptosis level was detected by caspase 3/7 activity and DNA fragmentation.Results: Cisplatin decreased cell viability and induced apoptosis of 5637 and T24 cells in a dose- and time-dependent manner. The increased LC3-II accumulation, p62 clearance, the number of LC3-positive puncta, and ALs in cisplatin-treated cells suggested that cisplatin indeed induces autophagy. Inhibition of cisplatin-induced autophagy using Baf A1, CQ, or ATG7/ATG12 shRNAs significantly enhanced cytotoxicity of cisplatin toward BC cells. These results indicated that cisplatin induced protective autophagy which may contribute to the development of cisplatin resistance and resulted in treatment failure. Mechanistically, upregulation of beclin-1 (BECN1) was detected in cisplatin-treated cells, and knockdown of BECN1 using shRNA attenuated cisplatin-induced autophagy and subsequently enhanced cisplatin-induced apoptosis.Conclusion: Collectively, the study results indicated that cisplatin-induced autophagy is mediated by BECN1 in BC cells. Therefore, combinative treatment using cisplatin and autophagy inhibitors could potentially overcome cisplatin resistance related to autophagy induction.

It is mostly associated with Parkinson’s disease, and very few cases in non-Parkinson’s disease have been reported. We report a case of punding associated with supratentorial ischemic stroke.Case presentation: We present a 70-year-old man with left posterior cerebral artery infarction with quetiapine-induced punding manifesting as repetitive unidirectional body turning. Remission of punding behavior ensued after cessation of quetiapine and administration of clonazepam.Conclusion: This case describes the clinical course of quetiapine-induced punding in a patient with left posterior cerebral artery infarction. It suggests clonazepam may serve as a treatment option for poststroke punding. Keywords: punding, stereotyped behavior, stroke, quetiapine, clonazepam

Ji-Fan Lin,1 Yi-Chia Lin,2,3 Shan-Che Yang,1 Te-Fu Tsai,2,3 Hung-En Chen,2 Kuang-Yu Chou,2,3 Thomas I-Sheng Hwang2–4 1Central Laboratory, Shin-Kong Wu Ho-Su Memorial Hospital, Taipei, Taiwan; 2Division of Urology, Department of Surgery, Shin-Kong Wu Ho-Su Memorial Hospital, Taipei, Taiwan; 3Division of Urology, School of Medicine, Fu-Jen Catholic University, New Taipei City, Taiwan; 4Department of Urology, Taipei Medical University, Taipei, Taiwan Background: Mammalian target of rapamycin (mTOR), involved in PI3K/AKT/mTOR pathway, is known to play a central role in regulating the growth of cancer cells. The PI3K/AKT/mTOR pathway enhances tumor survival and proliferation through suppressing autophagy, which sustains energy homeostasis by collecting and recycling cellular components under stress conditions. Conversely, inhibitors of the mTOR pathway such as RAD001 induce autophagy, leading to promotion of tumor survival and limited antitumor efficacy. We thus hypothesized that the use of autophagy inhibitor in combination with mTOR inhibition improves the cytotoxicity of mTOR inhibitors in bladder cancer.Materials and methods: The cytotoxicity of RT4, 5637, HT1376, and T24 human bladder cancer cells treated with RAD001 alone or combined with autophagy inhibitors (3-methyladenine (3-MA), bafilomycin A1 (Baf A1), chloroquine, or hydroxychloroquine) was assessed using the WST-8 cell viability kit. The autophagy status in cells was analyzed by the detection of microtubule-associated light chain 3 form II (LC3-II), using immunofluorescent staining and Western blot. Acidic vesicular organelle (AVO) formation in treated cells was determined by acridine orange vital staining. Inhibition of mTOR pathway by RAD001 was monitored by using a homemade quantitative polymerase chain reaction gene array, while phospho-mTOR was detected using Western blot. Induced apoptosis was determined by measurement of caspase 3/7 activity and DNA fragmentation in cells after treatment.Results: Advanced bladder cancer cells (5637, HT1376, and T24) were more resistant to RAD001 than RT4. Autophagy flux detected by the expression of LC3-II showed RAD001-induced autophagy. AVO formation was detected in cells treated with RAD001 and was inhibited by the addition of 3-MA or Baf A1. Cotreatment of RAD001 with autophagy inhibitors further reduced cell viability and induced apoptosis in bladder cancer cells.Conclusion: Our results indicate that simultaneous inhibition of the mTOR and autophagy pathway significantly enhances apoptosis, and it is suggested to be a new therapeutic paradigm for the treatment of bladder cancer. Keywords: autophagy, apoptosis, bladder cancer, chloroquine, RAD001

Good outcome predictors include milder severity of symptoms, no need for intensive care unit admission, early aggressive immunotherapy, and prompt tumor removal. We report a case of a young girl aged 3 years 2 months and diagnosed as recalcitrant anti-NMDA receptor encephalitis without any underlying neoplasm. The patient had initial symptoms of behavioral changes that progressed to generalized choreoathetosis and orofacial dyskinesia, which resulted in 6 months of hospitalization in the pediatric intensive care unit. One year after initial onset of the disease, she had only achieved the developmental age of an infant aged 6–8 months in terms of gross and fine motor skills, but she resumed total independence in activities of daily living after receiving extensive immunotherapy and 28 months of rehabilitation. Our brief review will help clinical practitioners become more familiar with this disease and the unique rehabilitation programs.

Our previous study successfully recycled wastes from the liquid crystal display (LCD) industry as the silica precursor. In this study, we substantiated the possibility of applying this material as a drug carrier. MSNs synthesized from the extraction of wastes from the manufacture of LCD panels were characterized as having an average diameter of 100 nm, a surface area of 788 m2/g, a uniform pore size distribution of 3.8 nm, and a pore volume of up to 1.04 cm3/g. Methotrexate and camptothecin were entrapped in MSNs at about 33.88% and 75.12%, respectively. The cell viability assay demonstrated that MSNs at 1 µg/mL had no significant influence on human lung fibroblast (WI-38) cells or ovarian cancer (ES-2) cells. A lactate dehydrogenase assay also indicated no inflammation occurred. Moreover, a hemolytic erythrocyte test indicated that the dose range of

We report a rare case of long-lasting paroxysmal dystonia associated with MS. The patient was a 40-year-old woman with relapsing- remitting MS for 6 years. During the latest attack of MS, she suffered from long-lasting paroxysmal dystonia in her left hand. Despite treatment with pulse high-dose intravenous methylprednisolone, interferon, and baclofen, along with occupational therapy, the dystonia persisted and significantly bothered her daily activities. Finally, she was treated with oral acetazolamide (250 mg, three times a day for 4 days), which was very effective for the control of her dystonia. The dystonic movement subsided without recurrence in a follow-up of 17 months. We advocate this effective and safe treatment for patients with paroxysmal dystonia associated with MS.
