  • 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.

Comorbid MR or ADHD increased the incidence of ASD in both sexes; comorbid MR or ADHD also decreased the male to female hazard ratio of ASD, with no significant differences in the incidence density of ASD between sexes. ADHD delayed diagnosis in both sexes. The results indicating unique vulnerabilities to MR/ADHD or under-identification of high-functioning females with ASD subjects. Increasing the diagnostic sensitivity of ASD in those with comorbid ADHD is important due to a delayed diagnostic age in this group.

    此研究探討性別和自閉症診斷行為關聯性,及共病智能障礙及過動症的影響。不同年齡男性自閉症發生率均較女性高。在男女均可觀察到共病智能障礙或過動症會增加自閉症發生率;共病也會降低自閉症發生之男女風險比。共病過動症在男女均會延後自閉症之診斷。結果暗示共病者之自閉症易感性、或在高功能自閉症女性的診斷難以辨識。
