  • 1. Z-Complementary Code Sets With Flexible Lengths From Generalized Boolean Functions.

    Wu, S. W., Şahin, A., Huang, Z. M., & Chen, C. Y. (2021). IEEE Access, 9, 4642-4652. Cite this article

    In the literature, most Z-complementary code set (ZCCS) constructions based on generalized Boolean functions lead to sequences of power-of-two length. In this study, we show that our proposed direct constructions result in ZCCSs of both power-of-two length and non-power-of-two length. Since the monomials of degrees more than 2 are employed in the proposed constructions, more ZCCSs can be obtained. The constructed ZCCSs admit the theoretical upper bound on the size for a ZCCS when the sequence length is a power of two. Also, the corresponding peak-to-average-power ratio (PAPR) is theoretically upper-bounded when a sequence in the set is used in OFDM. The proposed constructions extend the applications of ZCCSs in practical communication systems, e.g., multicarrier CDMA (MC-CDMA) system, by offering flexible sequence lengths, various set sizes, and bounded PAPR.

    We confirmed that IL-20 antibody injection at the moment of reperfusion reduces I/R-caused oxidative injuries, apoptosis, inflammation, as well as the elevation in markers of cardiac fibrosis and remodeling. We also proved that IL-20 antibody injection attenuates cardiac functional impairment, including the repressed EF and FS, the increased left ventricular end-diastolic and end-systolic volumes, and plasma markers of cardiac injury and heart failure. This study elucidates that IL-20 antibody might be favorable in lessening reperfusion injury in the treatment of AMI.

    We use high temporal resolution Geostationary Ocean Color Imager (GOCI) to monitor the spatial–temporal distribution of suspended sediment (SS) along the coastal waters of northern Taiwan which was affected by Typhoon Soudelor from 8 to 10 August 2015. The results show that SS concentration increased during 11–14 August and then decreased during 19–22 August. The mouths of the Dajia River and Tamsui River were hotspots of SS, ranging from 9 to 15 g/m3, during the two post-typhoon periods. It is also shown that maximum SS occurred in the west and east coastal water during 11–14 August and 19–22 August, respectively. Furthermore, an exponential decay model was used to compute the time when 90% of typhoon-induced SS was dissipated after Typhoon Soudelor. It was found that the mouths of the Tamsui River and Heping River had the longest time, with a range of 360–480 h.

    本文以高時間解析度GOCI衛星影像,觀測北台灣沿岸海水懸浮泥沙濃度(SS)受2015年8月蘇迪樂颱風影響之時空分佈。在颱風過後,SS分別於8月11–14日觀測期間上升,8月19–22日觀測期間下降,且大甲溪與淡水河之河口為高SS之熱區,達9–15 g/m3。以指數衰減模型計算減少90%颱風誘發的SS所需時間,發現淡水河與和平溪河口需要360–480小時。

    In this study, we aim to clarify the novel aptamer, Tx-01, clinical role and possible molecular mechanisms of Tx-01 in Ovarian cancer. Immunostaining and statistical analysis were performed to detect the interaction of Tx-01 and heat shock protein 70/Notch1 intracellular domain in OvCa. The in vitro and in vivo experiments demonstrated the potential mechanisms of Tx-01. Tx-01 reduced serous OvCa OVCAR3 cell migration and invasion and inhibited HSP70 nuclear translocation by interrupting the intracellular HSP70/NICD interaction. Furthermore, Tx-01 suppressed serous-type OVCAR3 cell tumor growth in vivo. Tx-01 acts as a prognostic factor through its interaction with membrane-bound HSP70 on ascetic circulating tumor cells and is reported to be involved in natural killer (NK) cell recognition and activation. Our data demonstrated that Tx-01 interacted with HSP70 and showed therapeutic and prognostic effects in serous OvCa. Tx-01 might be a potential inhibitor for use in serous OvCa treatment.

    Since the first clinical cancer treatment in 1978, photodynamic therapy (PDT) technologies have been largely improved and approved for clinical usage in various cancers. Due to the oxygen-dependent nature, the application of PDT is still limited by hypoxia in tumor tissues. Thus, the development of effective strategies for manipulating hypoxia and improving the effectiveness of PDT is one of the most important area in PDT field. Recently, emerging nanotechnology has benefitted progress in many areas, including PDT. In this review, we will discuss the state of the art of nanomedicine-based approaches for assisting PDT for treating hypoxic tumors, mainly based on oxygen replenishing and oxygen dependency diminishing strategies. We will emphasize emerging trends about the use of nanoscale metal–organic framework materials and the combination of PDT with immunotherapy. We further discuss future perspectives and challenges associated with these trends in both the aspects of mechanism and clinical translation.

    Bacteriophages are viruses that specifically infect bacteria, which have developed extraordinary proteins for recognizing and degrading their host. Inspired by the remarkable development of viral proteins, phage-derived proteins have been used for clinical treatment of multi-drug resistant (MDR) bacteria infection. For example, the polysaccharide depolymerase or endolysins were used to attenuate bacterial cell walls or to destroy the bacterial membrane. More recent efforts have addressed bacterial selection to treat drug-stress or phage infection. We, then, propose a combination strategy of co-treating MDR Acinetobacter baumannii with phage endolysin derived peptide and polysaccharide depolymerase (the tail fiber molecules). In the study, we surprisingly observed a temporary increase in resistance to colistin, used as the last-resort antibiotic for MDR Gram negative bacterial infection. Evaluation of the phage attacking behavior suggests the temporary increased resistance may be associated with an increased risk of drug-resistance during phage-antibiotic synergy in clinical MDR A. baumannii treatment.

    Pinus needle tea, which is very popular in Eastern countries, is claimed to have significant anti-aging effects. In this study, five undescribed compounds as well as seventy-two known compounds were characterized from the methanol extracts of P. taiwanensis needles. Most of the isolates were examined for their anti-inflammatory bioactivity, and six compounds exhibited significant inhibitions on superoxide anion generation and elastase release. These ingredients were subjected to docking computing to evaluate their binding affinity on the ghrelin receptor to explore the potentials of anti-aging effect. Three tested compounds formed a stable complex with the ghrelin receptor via hydrogen bonds and different types of interactions, and it suggested these flavonoids to be responsible for the potential anti-aging effects of pine needle tea.

    Photoelectrochemical reforming of plastic waste offers an environmentally-benign and sustainable route for hydrogen generation. Nonetheless, little attention was paid to develop electrocatalysts that can efficiently and selectively catalyze oxidative transformation of valueless plastic wastes into valued chemicals. Herein, we report on facile electrosynthesis of nickel-phosphorus nanospheres (nanoNi-P), and their versatility in catalyzing hydrogen generation, water oxidation, and reforming of polyethylene terephthalate (PET). Notably, composite of nanoNi-P with carbon nanotubes (CNT/nanoNi-P) requires −180 mV overpotential to drive hydrogen generation at -100 mA cm−2. Besides, CV-activated nanoNi-P (nanoNi-P(CV)) was shown to be capable of reforming PET into formate with high selectivity (Faradic efficiency= ∼100 %). Efficient and selective generation of hydrogen and formate from PET reforming is realized utilizing an Earth-abundant photoelectrochemical platform based on nanoNi-P(CV)-modified TiO2 nanorods photoanode and CNT/nanoNi-P cathode. This work paves a path for developing artificial leaf for simultaneous environmental mitigation and photosynthesis of renewable fuels and valued chemicals.

    This retrospective comparative effectiveness analysis used data from the population-based Taiwan Cancer Registry. Included patients were diagnosed with clinical stage III or IV oropharyngeal squamous cell carcinoma from 2007 to 2015 and were identified from the registry. Among 1180 patients, 694 patients (58.8%) were in the definitive chemoradiotherapy group and 486 patients (41.2%) were in the upfront surgical treatment group. The mean age was 54.59 years. Primary treatment with an upfront surgical procedure was associated with a decreased risk of death during the study period (HR: 0.81; P = .02). However, when adjusted for age, subsite, histological grade, and T and N classification, upfront surgical treatment was no longer associated with an increased risk of death during the study period (HR: 0.96; P = .70). Progressionfree survival was worse in the group receiving upfront surgical treatment than in the group receiving chemoradiotherapy (HR, 1.64; P = .02), and this difference persisted after adjusting for other factors associated with prognosis(HR, 1.72; p = .01). This study found that definitive chemoradiotherapy was associated with effectiveness that was comparable with that of upfront surgical treatment when adjusted for baseline factors associated with prognosis. These findings suggest that definitive chemoradiotherapy should be considered to avoid accumulating toxic effects associated with surgical treatment and chemoradiotherapy.

    Land subsidence caused by groundwater overexploitation is a critical global problem. The spatial distribution of land subsidence is crucial for effective environmental management and land planning in subsidence prone areas. Because of the nonlinear relationship between subsidence and drawdown due to groundwater exploitation in heterogeneous aquifers, a spatial regression (SR) model is developed to effectively estimate nonlinear and spatially varying land subsidence. Considering various data inputs in the Choshui River alluvial fan, the SR model offers a robust method for accurately estimating the spatial patterns of subsidence using only drawdown as input data.

    Early-onset schizophrenia (EOS) may have stronger familial aggregation and a more severe outcome than adult-onset schizophrenia (AOS). MicroRNA (miRNA) takes on dual roles as a genetic and epigenetic modulator, which mediate the influence of genetic risk. Neurological soft signs (NSS) are neurological abnormalities that may be intermediate phenotypes or endophenotypes for schizophrenia. We aimed to identify a set of aberrant neurodevelopmental-related miRNAs that could serve as potential biomarkers for EOS or schizophrenia with NSS. Receiver operating characteristic (ROC) analysis showed miR-137 dysregulation was correlated with almost all NSS subscales and, when EOS patients with NSS, miR-137 expression discriminated these patients from healthy controls to a greater extent (AUC = 0.957). MiR-34b had the highest ability to discriminate between EOS and AOS (AUC = 0.810), which may indicate different etiological pathways to disease onset. These findings support the potential for neurodevelopmental-related miRNAs to be used as indicators of vulnerability to EOS.

    Etoposide (ETO) has been used in treating adrenocortical tumor (ACT) cells. In this study, we showed that ETO treatment at 10 μM inhibited ACT cell growth by inducing cellular senescence rather than apoptosis. Several markers of cellular senescence, including activated senescence-associated β-galactosidase activity, elevated levels of p53, and down-regulation of lamin B1, were observed. We further found that ETO induced multiple centrosomes. The inhibition of multiple centrosomes accomplished by treating cells with either roscovitine or centrinone. DNA-PK-Chk2 signaling was activated by ETO treatment; inhibition of this signaling cascade alleviated multiple ETO-induced centrosomes and primary cilia followed by reducing cellular senescence. Autophagy was also triggered by ETO treatment. The inactivation of DNA-PK-Chk2 signaling reduced ETO-triggered autophagy; however, the inhibition of autophagy did not affect DNA-PK-Chk2 activation. Thus, ETO activated the DNA-PK-Chk2 cascade to facilitate autophagy. The activated autophagy further induced multiple centrosomes and primary cilia followed by triggering senescence.

    本研究發現當以濃度10 µM的etoposide (ETO)處理細胞時,會誘發cellular senescence,伴隨SA-β-GAL酵素活性會增加、p53上升和lamin B1下降。ETO會導致multiple centrosomes。ETO也會活化DNA-PK-Chk2 signaling,抑制此signaling會減少multiple centrosomes及primary cilia進而減少senescence,autophagy也受到相同的訊息路徑的調控,當抑制DNA-PK-Chk2 signaling會減少ETO所誘發的autophagy,而當抑制autophagy不會影響DNA-PK-Chk2 signaling的活化。因此ETO活化DNA-PK-Chk2 signaling以促進autophagy,進而誘導multiple centrosomes及primary cilia觸發senescence。

The data come from the Taiwan Database of Children and Youth in Poverty, which is a national longitudinal project measuring FI in five survey waves (2009-2017). We employed group-based trajectory modeling to classify 1921 participants aged 12-18 years into four FI trajectory groups: persistently low FI (24.8%), persistently moderate FI (64.7%), declining from high to low FI (4.1%), and food-secure groups (6.4%). Furthermore, a generalized estimating equation analysis was conducted the persistently moderate FI group was more likely to have mental (β = 0.30, [95% confidence interval 0.21-0.38]) and sleep problems (β = 0.39, [0.29-0.48]), as compared to food-secure adolescents. Our study describes the FI profile of adolescents from economically disadvantaged families. Healthcare providers can aid adolescents and provide guidance when appropriate.

    Prolonged sitting combined with an awkward posture might contribute to the increased risks of developing spinal pain. Maintaining an upright sitting posture is thus often suggested. This study aimed to investigate the effects of a wearable biofeedback sensor on maintaining an upright sitting posture. Twenty-one healthy young adults were recruited and performed a 1-h computer typing task twice, with and without using the active biofeedback device. The sagittal spinal posture during computer typing was measured using a three-dimensional motion analysis system. Using the wearable bio-feedback sensor significantly decreased the neck flexion, thoracic kyphotic, and pelvic plane angles compared with not using the sensor. Computer users and sedentary workers may benefit from using wearable biofeedback sensors to actively maintain an upright sitting posture during prolonged deskwork.

    To enhance remote sensing for maritime safety and security. High-frequency (HF) radar systems are a type of mainstream technology widely used in international marine remote sensing. However, effectively recognizing targets in spectra with intrinsic strong disturbance echoes and random environmental noise is still challenging. To avoid the above problem, this paper proposes an adaptive signal identification method to detect target signals based on a rapid and flexible threshold. By integrating a watershed segmentation algorithm, the subsequent direction result can be used to automatically compute the direction of arrival of the targets. To assist in the orientation of the object, forward intersections are integrated with the technique. Hence, the proposed technique can effectively recognize vessel echoes with automatic identification system (AIS) verification. Experiments have demonstrated the promising feasibility of the proposed method’s performance.

    In this report, we systematically characterized the compositions and ecological drivers of salivary microbiome in the cohorts of orally healthy, non-recurrent oral verrucous hyperplasia (OVH), and OVH–associated oral cancer at taxonomic and function levels, and compared them with the re-analysis of publicly available datasets through using bacterial 16S rRNA amplicon sequencing and in silico function analysis by PICRUSt2 (Phylogenetic Investigation of Communities by Reconstruction of Unobserved States 2). Diversity analyses showed the decline of core species numbers and the deregulation of metabolic pathways as host oral health deteriorated. Partitioned beta-diversity revealed an extremely high species turnover but low function turnover. Functional beta-diversity in saliva microbiome shifted from turnover to nestedness during oral carcinogenesis, which was not observed at taxonomic levels. Moreover, metabolic pathways of nucleotides, amino acids, fatty acids, and cell structure are strongly related with the disease progression. Using predicted functional profiles to elucidate the correlations to the oral health status thus shows superior performance than those using taxonomic data. Together, this study not only advances our understanding of the oral ecosystem in relation to oral carcinogenesis but also provide a new direction for using microbiome-based tools to study the interplay of the oral microbiome, metabolites, and host health.

    Collagenopathy is a rare genetic condition characterized by abnormality in either collagen structure or metabolism. Through whole exome sequencing (WES) complemented with multiplex ligation-dependent probe amplification, we identified the genetic etiologies for six cases with osteogenesis imperfecta (OI) in COL1A1 (p.T1298N, p.Q1280Pfs∗51, and p.G557Vfs∗23) and COL1A2 (c.1-1677_133-441del) as well as three cases with spondyloepiphyseal dysplasia congenita in COL2A1 (p.G1041S, p.G654S, and p.G441A). Co-occurrence of COL1A1 and WNT1 mutations was found in a patient with a mild OI phenotype but severe osteoporosis. These findings extended the pathogenic variant spectrum of COL1A1, COL1A2, and COL2A1 for type I and type II collagenopathies. Although WES provides a fast and accurate method to identify the genetic causes, its limitation of detecting CNVs because of variable capturing uniformity should be kept in mind when interpreting the results. We demonstrate that multiple genetic characterizing technologies can provide an accurate and efficient molecular diagnosis.

    Doping in semiconductors renders one serious drawback in triboelectric nanogenerator (TENG) as tribo-charges tend to leak for energy output. Therefore, a two-layer structure of Ga-doped ZnO/undoped-ZnO is proposed, where a ZnO thin film was first grown by sputter followed by Ga doping restricted to a shallow surface region by thermal diffusion. The results support that surface work function difference between two tribo-materials under the well preservation of trio-charges retention governs the charge transfer capability, where the output voltage and current of the ZnO film doped with 0.93 at% Ga can be enhanced by 16 and 13 times, respectively. Nevertheless, the larger work function of β-Ga2O3 than Ga-doped ZnO does not lead to larger output performance, implying the importance of carrier concentration in the performance of TENGs. We demonstrated a viable method to modify the work function of ZnO only confined to the surface through doping without disturbing the bulk, optimizing semiconductors for TENGs.

    Psoriasis affects more than 125 million people worldwide, and the diagnosis and treatment efficacy evaluation of the disease mainly rely on clinical assessments that could be subjective. While the compromised epidermal barrier function has been taken as the major cause of clinical manifestation of skin inflammation of psoriasis, very few methods can be used to effectively evaluate this function. In this study, we investigate the near infrared spectroscopic features of psoriatic (n = 21) and normal (n = 21) skin that could link to the epidermal barrier function. From the DRS measurements, it was found that the water bonding status and light scattering properties of psoriasis are significantly different from those of uninvolved or normal skin. The connection between these parameters to the epidermal barrier function and morphology is discussed. Our results suggest that objective evaluation of epidermal barrier function of psoriasis could be achieved using a simple DRS system.

    Strong coupling between an atom and a cavity has been utilized for quantum photonic devices such as deterministic single photon sources and quantum gates. The alignment between an atom and a cavity needs atom trapping and high vacuum equipment, which are hardly to be integrated into a microchip. Here, DNA strands connect a gold nanoparticle and a gold film to construct a nanocavity and simultaneously integrate a few fluorophores into the cavity to form a strong coupling unit. High cavity yield and strong coupling yield are achieved by this method. Combination of this method with e-beam lithography can further position strong coupling units on a specific location of a microchip. Furthermore, when we detune fluorophores embedded nanocavities, the polariton energy can fit into the curves derived from three sets of two-level systems, which indicates vibronic modes may be involved in the strong coupling systems.

    Antimicrobial peptides (AMPs) are intensively studied in terms of alternative drugs. Sub5 is a synthetic 12-mer AMP with substitutions of five amino acids of bactenecin 2A (Bac2A), a linear-ized bactenecin variant of bovine. Sub5 is highly effective against fungi with an ability to trans-locate cell membrane, but its targets are unknown. Systematic analysis of Sub5 targets will facilitate our understanding on its mechanism of action. In this study, we used high-throughput Saccharomyces cerevisiae proteome microarrays to explore the potential protein targets of Sub5. The screening results showed 128 potential protein targets of Sub5. Bioinformatics analysis of protein targets of Sub5 revealed significant gene ontology (GO) enrichment in actin related pro-cess of "actin filament-based process", "actin filament organization", "actin cortical patch or-ganization", regulation of "actin filament bundle assembly". Moreover, the other enriched cat-egories in GO enrichment mostly contained actin associate proteins. In total, 11 actin-associated proteins were identified in the protein targets of Sub5. Protein family (PFAM) enrichment anal-ysis shows protein domain enriched in actin binding, i.e., "Cytoskeletal-regulatory complex EF hand (helix E-loop-helix F motif)". Being consistent with GO analysis, Search Tool for the Re-trieval of Interacting Genes/Proteins (STRING) analysis of the protein targets of Sub5 showed ac-tin network with involvement of 15 protein targets. Along with actin-network, STRING analysis showed protein-protein interaction network in ribonucleoprotein, transcription and translation, chromosome, histone, and ubiquitin related, DNA repair, and chaperone. Multiple Expression motifs for Motif Elicitation (MEME) suite provided a consensus binding motif of [ED][ED]EEE[ED][ED][ED][ED][ED], in total of 75 protein targets of Sub5. This motif was present in 9 out of 15 actin-related proteins identified among protein targets of Sub5.

The interrupted timeseries analysis was performed to compare the incidence trend before and after the implementation of PCV13. After implementation, the significant decreasing trend of pneumococcal CAP (P-CAP) hospitalization corresponds to a 59% reduction in children < 1 year, 47% in children aged 2–5 years, 39% in adult aged 19–65 years, and 41% in elderly aged 66 years or older. The intensive care rate (6.8% to 3.9%), severe pneumonia cases (21.7 to 14.5 episodes per 100,000 children–years), and the need for invasive procedures (4.3% to 2.0%) decreased in children aged 2–5 years with P-CAP. This PCV13 implementation program in Taiwan not only reduced the incidence of P-CAP, but also attenuated disease severity, especially in children aged 2–5 years.

    Immune-mediated arthritis is an important chronic inflammatory disease of joints. The cellular and molecular factors contributing to the joint inflammation in different redox conditions have not been clearly elucidated. Previous research showed that phagocyte-produced reactive oxygen species (ROS) plays an anti-inflammatory role in K/BxN serum-transfer arthritis and NOX2-deficient mice tend to have more severe arthritis. Although many leukocytes play critical roles in the development of immune-mediated arthritis, the role of neutrophils, which are the main producers of ROS in inflammation, is still controversial. We hence assessed the immunomodulatory function of neutrophils from arthritic joints of NOX2-deficient and wild type mice in this study. We found more neutrophils accumulation in NOX2-deficient inflamed joints. RNA-sequencing and quantitative PCR revealed significantly increased expression of acute inflammation genes including IL1b, Cxcl2, Cxcl3, Cxcl10 and Mmp3 in activated neutrophils from the inflamed joints of NOX2-deficient mice. Moreover, gene set enrichment analysis (GSEA) showed enriched gene signatures in type I and II IFN responses, IL-6-JAK-STAT3 signalling pathway and TNF-a signalling pathway via NF-kB in NOX2-deficient neutrophils. In addition, we found that NOX2-deficient neutrophils expressed lower levels of PD-L1 and were less suppressive than WT neutrophils. Moreover, treatment of PD-L1-Fc decreased cytokine expression and ameliorated the severity of inflammatory arthritis. Our results suggest that NOX2-derived ROS is critical for regulating the function and gene expression in arthritic neutrophils. Both the strong pro-inflammatory and weakened anti-inflammatory functions of neutrophils due to abnormal redox regulation may be targets of treatment for immune-mediated arthritis.

    免疫引起之關節炎是一種慢性發炎性關節疾病,在不同的氧化還原狀態下的細胞與分子如何造成免疫性關節炎這部分還尚未研究清楚。先前的研究指出菸醯胺腺嘌呤二磷酸氧化酶 (NOX2)所產生的活性氧分子(ROS)在K/BxN血清引起的關節炎中具有抗發炎的功能,並且NOX2缺陷的小鼠會產生更加嚴重的免疫性關節炎。雖然很多種白血球在免疫性關節炎的發展中都扮演了角色,但是主要表現NOX2的嗜中性球的角色還尚未釐清。所以,我們想要研究NOX2缺陷的嗜中性球以及正常的嗜中性球在免疫性關節炎中的免疫調節功能。初步的研究結果發現在NOX2缺陷的小鼠關節中有比較多的嗜中性球浸潤和累積。接著,在使用RNA定序技術分析抗體活化之NOX2缺陷嗜中性球的基因表現之後,我們發現急性發炎性基因包括: IL1b、Cxcl2、Cxcl3、Cxcl10和Mmp3 等等的基因表現都上升。再進一步地使用gene set enrichment analysis (GSEA) 分析RNA定序的結果後發現,第一和第二型干擾素反應基因群、介白素6-JAK-STAT3訊息傳遞路徑基因群以及腫瘤壞死因子a經由NF-kB的訊息傳遞路徑基因群的表現量都在NOX2缺陷的嗜中性球中提高了。同時,我們發現NOX2缺陷嗜中性球抑制正常T細胞增生的功能較弱,其免疫檢查點的表現量也較少。在加強了免疫檢查點在NOX2缺陷的小鼠表現量之後,細胞激素的表現以及關節炎的嚴重性都降低了。總而言之,活性氧分子,特別是由NOX 2所產生的,在免疫引起的關節炎中具有極為重要的免疫調節功能,所以調節氧化還原狀態是具有潛力的目標可用於治療免疫引起的關節炎。

    Chemotherapy-induced cognitive impairment (CICI) is an increasing awareness due to prolonged survival following cancer chemotherapy in cancer patients. Multiple mechanisms have been proposed for CICI induced by various chemotherapeutic agents; however, hippocampal damage and impaired neurogenesis may be one of the mechanisms. The aim of our study was to investigate the interplay between impaired neurogenesis, inflammation, and the symptoms of CICI, including spatial memory dysfunction and mood alteration, in a paclitaxel-treated mice model. In addition, we demonstrated that memantine may serve as a potential therapeutic agent for paclitaxel- induced CICI by modulating neurogenesis and inflammation. However, the treatment regimen may lead to variations in the treatment efficacy, especially in terms of mood dysfunction. Further translational studies may be developed to evaluate the clinical efficacy of memantine in human CICI studies.

    A novel detection and severity classification algorithm using deep learning approaches was developed in this research to classify PD severity levels based on vertical ground reaction force (vGRF) signals. Different variations in force patterns generated by the irregularity in vGRF signals due to the gait abnormalities of PD patients can indicate their severity. The detection algorithm comprises preprocessing, feature transformation, and classification processes. In preprocessing, the vGRF signal is divided into 10, 15, and 30-s successive time windows. In the feature transformation process, the preprocessed time-domain vGRF signal is modified into a time-frequency spectrogram using continuous wavelet transform (CWT). Then, principal component analysis (PCA) is used for feature enhancement. Finally, different types of convolutional neural networks (CNNs) are employed as deep learning classifiers for classification. The best average accuracy of the proposed PD severity stage detection algorithm was 96.52% using ResNet-50 with vGRF data from the PhysioNet database.

    After successful surgeries for patients with rhegmatogenous retinal detachment, the most common cause of retinal redetachment is proliferative vitreoretinopathy (PVR), which causes severe vision impairment and even blindness worldwide. Until now, the major treatment for PVR is surgical removal of the epiretinal membrane, while effective treatment to prevent PVR is still unavailable. Therefore, we investigated the potential of doxycycline, an antibiotic in the tetracycline class, to treat PVR using a mouse model. We used the human retinal pigment epithelial cell line, ARPE-19, for in vitro and in vivo studies to test doxycycline for PVR treatment. We found that doxycycline suppressed the migration, proliferation, and contraction of ARPE-19 cells with reduced p38 MAPK activation and total MMP activity. Intravitreal doxycycline and topical tetracycline treatment significantly ameliorated the PVR severity induced by ARPE-19 cells in mice. PVR increased the expression of MMP-9 and IL-4 and p38 MAPK phosphorylation and modestly decreased IL-10. These effects were reversed by doxycycline and tetracycline treatment in the mouse retina.

    Fang, S.-Y., Lin, P.-J., & Kuo, Y.-L. (2021). JMIR Mhealth Uhealth, 9(12), e31092 Cited this article

    Most of the women are not well prepared to make decision for undergoing breast reconstruction after mastectomy. Recent studies revealed that women with treatment decision-making difficulties experience chronic psychological distress. Using decision aids that providing information and facilitate value clarification during the process of treatment decision making can improve decision-related outcomes. An application (app) named “Pink Journey” was designed to help women make breast reconstruction decision after mastectomy.This randomized controlled trial included women who were over 20 years of age and were newly diagnosed with breast cancer and candidates for mastectomy. After intervention, decision conflict, decision regret, anxiety, depression, and body image scales were measured at1 week after the intervention and 1 month, 8 months, and 12 months after surgery. Results revealed that “Pink Journey” decision aid that combines surgery information and values clarification can help women reduce their body image distress after 1 year follow-up and did not increase anxiety and depression.

    對於乳癌婦女而言,決定是否接受乳房重建手術是一大考驗,大多數的女性並未做好乳房重建手術的術前準備。我們設計了一款專門幫助乳癌婦女進行乳癌重建決策的粉紅旅程APP,納入年滿20歲初診斷乳癌切需切除全乳房的婦女進行介入,並在介入後1週、手術後1個月、8個月、12個月進行追蹤,結果發現結合手術資訊和價值觀澄清的決策輔助於12個月的追蹤後顯著減少婦女身體心像困擾,不增加焦慮與憂鬱。

    In this article, we attempt to provide an explanation to why there are different levels of media freedom in autocracies. We argue that this variation can be partially explained by the power dynamics within their ruling coalitions, among other reasons suggested in the previous literature. We argue that dictators need to allow for a higher level of media freedom when sharing more power with other elites. Specifically, dictators create transparency through media freedom to induce trust and cooperation among elites within the regime. We confirm the hypothesis by analyzing data from 98 dictatorships from 1960 to 2010. Our finding is robust to different model specifications. This article contributes to the literature by showing that authoritarian media freedom is determined by not only dictators’ need for local information as suggested in the extant literature, but also the power-sharing structure within their ruling coalitions.

    在這篇文章中,我們為在不同威權國家中,為什麼存在不同程度的媒體自由提出一個解釋。我們的理論主張,如果菁英間的權力分享程度越低,媒體自由程度會越小,若菁英間權力分享程度越高,則媒體自由程度會越大。這是因為媒體自由可以增加資訊透明度,使得菁英間的權力分享得以維持,而若獨裁者不需要與其他精英分享權力時,便沒有開放資訊透明的需求。我們分析涵蓋 1960到2010年間、98 個威權國家的資料,驗証了這個理論。

  • 35. The significance of SMARCB1 in the pathogenesis of renal cell carcinoma with rhabdoid features.

    Malignant neoplasms with rhabdoid features are usually associated with a poor prognosis. Renal cell carcinoma with rhabdoid features (RCC-RF) is an aggressive histologic variant in the adults and is usually unresponsive to standard chemotherapy. Expression of SMARCB1/INI1 was assayed in primary RCC-RF (n = 5). Stable INI1 with/without prostaglandin E2 receptor 1 (EP1) knockdown (KD) cell lines were created in the ACHN RCC cell line and analyzed for epidermal growth factor receptor (EGFR)-related signaling pathways. The potential importance of co-targeting EP1 for RCC-RF was examined using a tumorigenicity assay. Expression of INI1 was markedly reduced at both transcriptional and translational levels in RCC-RF. Loss of INI1 protein expression was confirmed in the nuclei of rhabdoid cells (n = 8). The growth rate of ACHN cells was significantly (P < 0.05) increased when INI1 was knocked down. Increase of migration (2.37 times) and invasion (2.5 times) in vitro was also demonstrated in INI1 KD cells. The ACHN INI1 KD cells were resistant to Sorafenib, while become more sensitive to Everolimus treatment in vitro compared with vector control. EGF treatment activated the phospho-EGFR expression, PI3K-AKT and MAPK pathways in stable INI1 KD cells in vitro. PGE2 treatment also activated the AKT and ERK pathways in vitro, suggestive of a signaling crosstalk between EP1 and EGFR in INI1-related RCC. Knocking down of EP1 significantly (P < 0.001) inhibited the proliferation and migration of ACHN INI1 KD cells in vitro and suppressed the tumor growth in NOD/SCID mice (P < 0.001). Inactivation of INI1 may involve in the pathogenesis of RCC-RF. Co-targeting PGE2/EP1 pathway with Everolimus could be considered in the management of patients with INI1-related RCC.

    具有橫紋肌樣特徵的惡性腫瘤通常預後不良。具有橫紋肌樣特徵的腎細胞癌 (RCC-RF) 是成人的侵襲性組織學變異,通常對標準化療無反應。在初級腎細胞癌中檢測到 SMARCB1/INI1基因的表現◦ 在持續表現INI1基因的腎細胞癌模式中,比較把前列腺素 E2 受體 1 (EP1) 剔除後,偵測表皮生長因子受體 (EGFR)相關訊號傳遞是否受到影響◦ 使用致瘤性實驗分析檢測共同治療因子EP1 對 RCC-RF 的潛在重要性。在 腎細胞癌模式 中,INI1 在RNA及蛋白質表現上均顯著降低。在橫紋肌細胞(n = 8)的細胞核中也證實了 INI1 蛋白的喪失。為了確認類橫紋肌上皮腎細胞癌中發病機制之重要性,我們利用 ACHN 細胞株來建立 INI1 穩定下降的細胞株。在 INI1 表現之後,伴隨的類橫紋肌特徵、增加細胞增生及細胞爬行速度顯著增加。然而在細胞存活率實驗當中發現在外加 VEGFR 的抑制劑(蕾莎瓦(Sorafenib)後發現腫瘤細胞有顯著的抗藥性,而 mTOR 抑制劑-癌伏妥(Everolimus)對於 ACHN INI1 表現量穩定下降的細胞株則具有顯著專一性抑制的效果,也因此確立了發展多標靶抗癌藥物治療策略的潛力。在利用 microarray 技術分析後所得到的 1024 上升和 908 下降的基因群中,我們挑選前列腺素 E 受體家族做為研究目標,因為其可接收 PGE2 的訊號,而且參與 VEGF-C 所產生的癌化,以及和EGFR 下游的傳導路徑有交互作用。利用 RT-PCR 及 Western blot 分析後,發現在 INI1表現量下降以後,外加生長因子EGF活化磷酸化EGFR, PI3K-AKT, MAPK等訊息傳遞蛋白的表現◦再深入探討 PGE2/COX 的訊息傳遞路徑之後,發現外加PGE2後, 能活化AKT及ERK等訊息傳遞蛋白表現,此結果證實了在 INI1表現量相關的腎細胞癌細胞株中EP1 及EGFR有互相影響的訊息傳遞作用◦當把EP1基因剔除後發現顯著(P < 0.001)抑制了ACHN INI1 KD細胞的增殖和遷移,並抑制了 NOD/SCID 小鼠的腫瘤生長(P < 0.001)。 INI1 的失活可能參與 橫紋肌樣特徵的腎細胞癌 之發病機制。未來可進一步考慮將 PGE2/EP1 通路與依維莫司(Everolimus)藥物聯合用於 INI1 相關 的腎細胞癌 患者其治療方針上。

  • 36. Spatially varying effects of measured confounding variables on disease risk.

    Wu, C.-C., Chu, Y.-H., Shete, S., & Chen, C.-H. (2021). International Journal of Health Geographics, 20(1), 45. Cited this article

    The presence of considerable spatial variability in incidence intensity suggests that risk factors are unevenly distributed in space and influence the geographical disease incidence distribution and pattern. As most human common diseases are complex traits and as more factors associated with increased risk are discovered, spatial models are needed that investigate geographical variability in the association between disease incidence and confounding variables and evaluate spatially varying effects on disease risk related to known risk factors. We proposed a spatial model that incorporates information on known risk factors, previously detected geographical disease clusters of peak incidence and paucity of incidence, and their interactions as covariates into the framework of interaction regression models with linear effects. The spatial scan statistic and the generalized map-based pattern recognition procedure that we recently developed were both considered for geographical disease cluster detection. The application to the sudden infant death syndrome incidence data with confounding variables of race and gender demonstrates the ability of our proposed model to estimate spatially varying associations between disease incidence and confounding variables and distinguish spatially related risk factors from spatially constant ones.

    空間中疾病發生率高低的變異性相當大,此現象可能因危險因子在空間中分布不均所導致,並且會影響地理上疾病發生率的分布與圖像。由於大部分人類常見的疾病是複雜性疾病,以及隨著時間的推移,越來越多與風險相關的因素被發現,因此以空間模型來調查疾病發生率與干擾因子之間在地理變異性的關聯是有需要的,並且評估與疾病風險相關的已知危險因子在空間變化上的影響。我們提出一個空間模型將已知危險因子的資訊、預先檢測出空間疾病群聚中的高發生率與低發生率地區,以及共變量之間的交互作用整合到線性交互回歸模型的框架中。而spatial scan statistic與我們最近提出的generalized map-based pattern recognition procedure都被用在地理疾病群聚檢測上。應用嬰兒猝死症發生率數據以及該疾病的干擾因子例如種族與性別,來證明所提出的模型對於估計疾病發生率與干擾因子之間在空間變化上的關聯是有效的,並從顯著危險因子中再辨別出與空間相關或沒有空間相關的危險因子。
