Abstract
INTRODUCTION Despite the serious risks of diabetes with hepatitis C virus (HCV) infection, this preventable comorbidity is rarely a priority for HCV elimination. We aim to examine how a shared care model could eliminate HCV in patients with diabetes (PwD) in primary care. METHODS There were 27 community-based Diabetes Health Promotion Institutes in each township/city of Changhua, Taiwan. PwD from these institutes from January 2018 to December 2020 were enrolled. HCV screening and treatment were integrated into diabetes structured care through collaboration between diabetes care and HCV care teams. Outcome measures included HCV care continuum indicators. Township/city variation in HCV infection prevalence and care cascades were also examined. RESULTS Of the 10,684 eligible PwD, 9,984 (93.4%) underwent HCV screening, revealing a 6.18% (n = 617) anti-HCV seroprevalence. Among the 597 eligible seropositive individuals, 507 (84.9%) completed the RNA test, obtaining 71.8% positives. Treatment was initiated by 327 (89.8%) of 364 viremic patients, and 315 (86.5%) completed it, resulting in a final cure rate of 79.4% (n = 289). Overall, with the introduction of antivirals in this cohort, the prevalence of viremic HCV infection dropped from 4.44% to 1.34%, yielding a 69.70% (95% credible interval 63.64%-77.03%) absolute reduction. DISCUSSION Although HCV prevalence varied, the care cascades achieved consistent results across townships/cities. We have further successfully implemented the model in county-wide hospital-based diabetes clinics, eventually treating 89.6% of the total PwD. A collaborative effort between diabetes care and HCV elimination enhanced the testing and treatment in PwD through an innovative shared care model.

Abstract
This study tested whether combined dapagliflozin and entresto would be superior to mere one therapy on protecting the residual renal function and integrity of kidney parenchyma in hypertensive kidney disease (HKD) rat. In vitro results showed that the protein expressions of oxidative-stress/mitochondrial-damaged (NOX-1/NOX-2/oxidized-protein/cytosolic-cytochrome-C)/apoptotic (mitochondrial-Bax/cleaved caspeases 3, 9)/cell-stress (p-ERK/p-JNK/p-p38) biomarkers were significantly increased in H2O2-treated NRK-52E cells than those of controls that were reversed by dapagliflozin or entresto treatment. Adult-male SD rats (n = 50) were equally categorized into group 1 (sham-operated-control), group 2 (HKD by 5/6 nephrectomy + DOCA-salt/25 mg/kg/subcutaneous injection/twice weekly), group 3 (HKD + dapagliflozin/orally, 20 mg/kg/day for 4 weeks since day 7 after HKD induction), group 4 (HKD + entresto/orally, 100 mg/kg/day for 4 weeks since day 7 after HKD induction), and group 5 (HKD + dapagliflozin + entresto/the procedure and treatment strategy were identical to groups 2/3/4). By day 35, circulatory levels of blood-urine-nitrogen (BUN)/creatinine and urine protein/creatinine ratio were lowest in group 1, highest in group 2, and significantly lower in group 5 than in groups 3/4, but no difference between groups 3/4. Histopathological findings showed the kidney injury score/fibrotic area/cellular expressions of oxidative-stress/kidney-injury-molecule (8-OHdG+/KIM-1+) exhibited an identical trend, whereas the cellular expressions of podocyte components (synaptopodin/ZO-1/E-cadherin) exhibited an opposite pattern of BUN level among the groups. The protein expressions of oxidative stress/mitochondrial-damaged (NOX-1/NOX-2/oxidized protein/cytosolic-cytochrome-C/cyclophilin-D)/apoptotic (mitochondrial-Bax/cleaved-caspase 3)/mitochondrial-fission (PINK1/Parkin/p-DRP1)/autophagic (LC3BII/LC3BI ratio, Atg5/beclin-1)/MAPK-family (p-ERK/p-JNK/p-p38) biomarkers displayed a similar pattern, whereas the protein expression of mitochondria-biogenesis signaling (SIRT1/PGC-1α-Mfn2/complex I-V) displayed an opposite pattern of BUN among the groups. In conclusion, combined dapagliflozin-entresto therapy offered additional benefits on protecting the residual kidney function and architectural integrity in HKD rat.

Abstract
PURPOSE/OBJECTIVE(S) I-125 radioactive seeds embedded in an eye plaque is used to deliver the radiation dose of 85Gy to the apex of the tumor. However, it is challenging to treat a lesion in height (>10 mm) because of a high dose (> 500 Gy) to sclera. A staged radiotherapy (SRT) has been implemented successfully in stereotactic radiosurgery when a single dose is risky for a bigger sized lesion. The hypothesis of this work is that the SRT works for eye plaque brachytherapy of uveal melanoma to break the single fraction into two. To apply the concept of SRT, the following questions need to be answered: What are the two fraction doses? What is the time interval between the two fractions? In this work, the two split fraction doses and time interval are calculated using the "incomplete-repair' model. MATERIALS/METHODS Equation (1) is the linear-quadratic (LQ) model. f(x) is the cell survival curve (SC). Equation (2) and (3) are radiobiological model developed dealing with the split doses by considering the incomplete repair. Ln(f(x)) = -αx - βx2 (1) Ln(fn(x, Ɵ)) = nLn(f(x))-nβx2hn(Ɵ) (2) hn(Ɵ) = (2/n)[ Ɵ/(1- Ɵ)][n-(1- Ɵn)/(1- Ɵ)] (3) Ɵ = exp(-µΔt) (4) x represents the fraction dose, Ɵx is the initial segment of the survival curve, Ɵ determines the rate at which repair proceeds. n is fraction number and µ represent repair constant which equals to ln2/T1/2. T1/2 is the half-life of I-125. For continuous dose vt delivered at dose rate v for time t, with repair constant µ, the LQ model is modified as Ln (f(vt, µ)) = -α(vt) -β(vt)2g(µt) (5) g(µt) = 2[µt-1+exp(-µt)]/(µt)2 (6) Assuming biological effective dose (BED) is the same for the single fraction and split two fractions, SC when n = 1 should be same as when n = 2. Therefore, the equation (7) is derived. Ɵ = [(α/β)x1 - 2(α/β)(x2)2 + (x1)2]/2(x2)2 - 1 (7) x1 is single fraction dose of 85Gy, x2 is the split dose to two fractions. α/β ratio of 10 Gy is used. By fitting the equation (7), the ranges of doses and time intervals were determined. RESULTS The fraction doses and time interval to get the same BED as single fraction of 85 Gy are determined from 45 Gy to 50 Gy with time interval of 22 days to 76 days for staged brachytherapy eye plaque (SBEP). Our result is matched the treatment protocol for SBEP reported, e.g., 1st fraction dose of 40Gy and 50 Gy of 2nd fraction with 73 days of time interval are used. The max. dose of scleral dose is 328 Gy compared to the single fraction scleral dose of 543Gy. CONCLUSION This work could provide guidelines in SBEP in dosage and time interval. The height of tumor matters the most in the SBEP since the taller the tumor, the higher dose to the sclera is. Reference.

Abstract
PURPOSE/OBJECTIVE(S) The purpose of this study is to compare the dosimetric quality and dose to surrounding normal tissue of HyperArc-based stereotactic radiotherapy (SRT) technique with a frameless robotic radiosurgery system for patients with multiple brain metastases. MATERIALS/METHODS Nineteen patients with multiple brain metastases (2-5 lesions) treated in our center were enrolled. The prescribed dose was 2100 cGy to 3250 cGy in three to five fractions. In order to determine the dosimetric quality, we compared the conformity index (CI), Gradient radius (GR), homogeneity index (HI), dose distribution in planning target volume, and dose to several organs at risk (OARs). All of the data were compared using pair-T test. RESULTS Both planning systems have prescribed dose coverage to GTV and PTV with no significant difference (P = 0.243; P = 0.312). The conformity index (CI), and homogeneity index (HI) were 1.27 ±0.022, and 1.08 ±0.006, respectively, for HyperArc plan and 1.76 ±0.065 and 1.22 ±0.009, respectively, for the CK plan (both, P< 0.001). The Gradient radius (GR) was 0.732 ±0.056 cm for HyperArc plan and 0.847 ±0.762 cm for CK plan (P = 0.002). These indicated that HyperArc plan had better CI, HI, and GR when compared to CK plan. Maximum dose to brainstem for HyperArc and CK plans were 485.1 ±128.65 and 723.6 ±126.93 cGy, respectively (P < 0.001). Moreover, HyperArc plan had less mean dose to optic chiasm, bilateral eyes, bilateral lens, and bilateral optic nerves (all, P < 0.05). Brain V5, V12, V24 were all much smaller in HyperArc plan (all, P < 0.05), indicating that HyperArc plan delivered less dose to normal brain tissue. CONCLUSION For patients with two to five brain metastases, HyperArc-based SRT provide excellent dosimetric quality and less dose to normal tissue.

Abstract
Background We estimated healthcare resource utilization (HRU) and costs in patients with generalized myasthenia gravis (gMG) in Taiwan. Methods This retrospective population-based, matched cohort study used the National Health Insurance Research Database to identify prevalent patients with gMG (cases) in 2019. In total, 2537 cases were matched (1:4) by age, sex, and urbanization level to 10148 randomly selected patients without gMG (comparators). A generalized linear regression model predicted the frequency of HRU and costs among service users. Costs attributable to gMG were obtained by subtracting all-cause HRU costs incurred by comparators from cases. Results The mean age of all patients was 54.99 years and 55.97% were female. Compared with comparators, cases had significantly higher rates of hypertension (33.03%/24.26%), diabetes mellitus (18.92%/11.37%), malignancies (16.00%/4.08%), cardiovascular disease (11.35%/8.12%), thyroid-related conditions (5.99%/1.16%), respiratory illness/disorders (4.38%/1.22%), and neurotic disorders (4.65%/2.6%). Amongst users of healthcare resources, cases had a mean 10 additional outpatient visits, 0.62 inpatient stays, and 0.49 emergency room visits in 2019 compared with comparators (p < 0.0001 for all). The mean (standard deviation) difference in all-cause healthcare costs between cases and comparators was NT$ 94997 (76431) [US$ 3133 (2521)], and was significantly higher for all categories (outpatient, inpatient, emergency room, drugs; p < 0.0001 for all). Among employed persons, 13.18%/7.59% of cases/comparators changed employment status during the study (p < 0.0001). Conclusion gMG presents a substantial burden on HRU and healthcare costs in Taiwan. A high attrition rate from full-time employment suggests additional societal costs. Improved treatments are needed to alleviate the burden of disease on individuals, healthcare systems, and economies.

Abstract
Background The prevalence of myasthenia gravis is increasing in many countries, including Asia. As treatment options expand, population-based information about the disease burden can inform health technology assessments. Methods We conducted a population-based retrospective cohort study using the Taiwan National Healthcare Insurance Research database and Death Registry to describe the epidemiology, disease burden and treatment patterns of generalized myasthenia gravis (gMG) from 2009 to 2019. Episodes of hepatitis B virus (HBV) infection or reactivation were explored. Results The number of patients with gMG increased from 1,576 in 2009 to 2,638 in 2019 and the mean (standard deviation) age from 51.63 (17.32) to 55.38 (16.29) years. The female:male ratio was 1.3:1. Frequently reported co-morbidities were hypertension (32-34% of patients), diabetes mellitus (16-21%) and malignancies (12-17%). The prevalence of patients with gMG increased annually from 6.83/100,000 population in 2009 to 11.18/100,000 population in 2019 (p < 0.0001). There was no temporal trend in all-cause fatality rates (range 2.76-3.79/100 patients annually) or gMG incidence rates (2.4-3.17/100,000 population annually). First-line treatment was with pyridostigmine (82%), steroids (58%), and azathioprine (11%). There was minimal change in treatment patterns over time. Among 147 new HBV infections, 32 (22%) received ≥4 weeks of antiviral therapy suggesting chronic infection. The HBV reactivation rate was 7.2%. Conclusion The epidemiology of gMG in Taiwan is evolving rapidly, with higher prevalence rates and increasing involvement of older age-groups suggesting a growing burden of disease and associated healthcare costs. HBV infection or reactivation may pose a previously unrecognized recognized risk for patients with gMG receiving immunosuppressants.

Abstract
BACKGROUND Diabetic kidney disease (DKD) is one of the most significant public health burdens worldwide. This study explored the renal protections of combined adipose-derived mesenchymal stem cells (ADMSCs) and empagliflozin (EMPA) in DKD rats. METHODS Adult-male-SD rats were equally allocated into group 1 (sham-operated-control), group 2 (DKD), group 3 (DKD + EMPA/20 mg/kg/day since day-14 after CKD-induction), group 4 [DKD + ADMSCs (6.0 × 105/intrarenal-arterial-injection/post-day-28, followed by 1.2 × 106/intravenous injection post-days 35 and 42 after CKD-induction, i.e., defined as repeated administration)] and group 5 (DKD + ADMSCs + EMPA) and kidney was harvested post-day-60 CKD-induction. RESULTS The result showed that the blood sugar and circulatory levels of BUN/creatinine and the ratio of urine protein/creatinine at day 60 were greatly increased in group 2 as compared the SC (i.e., group 1), significantly increased in groups 3 and 4 than in groups 5, but these parameters showed the similar manner in groups 3 and 4, except for blood sugar that was significantly lower in group 3 than in group 4 (all p < 0.0001). The protein levels of inflammation (NF-κB/FNF-α/MMP-9)/oxidative-stress (NOX-1/NOX-2/oxidized protein/p22-phox)/apoptosis (cleaved-caspase-3/cleaved-PARP/mitochondrial-Bax)/fibrosis (TGF-β/Smad 3)/mitochondrial/DNA-damaged (p-DRP1/γ-H2AX) biomarkers revealed a similar manner of creatinine level among the groups (all p < 0.0001). Kidney injury score/fibrotic area/oxidative-stress score (8-OHdG) and cellular levels of kidney-damaged biomarkers (KIM-1/γ-H2AX) showed a unanimous manner. In contrast, the cellular expressions of podocyte components (ZO-1/synaptopodin) revealed an antithetical manner of creatinine among the groups (all p < 0.0001). CONCLUSION Combined ADMSCs-EMPA was superior to just one therapy for protecting kidney function and ultra-structural integrity in DKD rodents.

Abstract
BACKGROUND Treating marginalized populations with HCV infection for elimination is faced with the challenge for the integration of HCV screening service offered for patients often moving across multiple settings. We envisaged a novel collaborative care approach to identify to what extent HCV patients overlapped between and within these multiple institutions and reported the findings of treatment coverage of these marginalized populations after HCV care cascades. METHODS We enrolled 7765 patients residing in the Changhua County, Taiwan offered with HCV screening from correctional institutions, HIV clinics, methadone clinics, and the existing HIV surveillance program (four subgroups including police-arrested people, probationers, non-injection drug user, and high-risk behavior people) between 2019 and 2020. The collaborative care and information were integrated through a teamwork of gastroenterologists, psychologists, infectious disease specialists, and nursing coordinators under the auspices of local health authority. RESULTS The overall participation rate in HCV screening was 92.65% (7194/7765). The prevalence rate was the highest in methadone clinics (90.17%) followed by correctional institutions (37.67%), HIV clinics (34.60%), and the surveillance program (18.14%). We found 25.41% (77/303) of methadone clinic patients, 17.65% (129/731) of HIV clinic patients, and various proportions for 44.09% (41/93) of deferred prosecuted or probationers under surveillance program were also recruited into other settings. Individuals' patient flow within setting was more frequent than that between setting. After calibrating the overlap of patient flow, a total of 1700 anti-HCV positives out of 4074 after screening were traced with available follow-up information to complete 92.52% treatment coverage of 1177 RNA-positives (77.23%) diagnosed from 1524 undergoing RNA testing with similar findings across multiple settings. CONCLUSION A new collaborative integrated care was adopted for elucidating patient flow between and within multiple settings in order to calibrate the accurate demand for HCV care cascades and enhance HCV treatment coverage in marginalized populations.

Abstract
To improve color conversion performance for color display application, we study the near-field-induced nanoscale-cavity effects on the emission efficiency and Förster resonance energy transfer (FRET) under the condition of surface plasmon (SP) coupling by inserting colloidal quantum dots (QDs) and synthesized Ag nanoparticles (NPs) into surface nano-holes fabricated on a GaN template and an InGaN/GaN quantum-well (QW) template. In the QW template, the inserted Ag NPs are close to either QWs or QDs for producing three-body SP coupling to enhance color conversion. Time-resolved and continuous-wave photoluminescence (PL) behaviors of the QW- and QD-emitting lights are investigated. The comparison between the nano-hole samples and the reference samples of surface QD/Ag NP shows that the nanoscale-cavity effect of the nano-hole leads to the enhancements of QD emission, FRET between QDs, and FRET from QW into QD. The SP coupling induced by the inserted Ag NPs can enhance the QD emission and FRET from QW into QD. Its result is further enhanced through the nanoscale-cavity effect. The relative continuous-wave PL intensities among different color components also show the similar behaviors. By introducing SP coupling to a color conversion device with the FRET process in a nanoscale cavity structure, we can significantly improve the color conversion efficiency. Simulation results confirm the basic observations in experiment.

Abstract
BACKGROUND Whole-exome sequencing (WES) facilitates the diagnosis of hereditary neuromuscular disorders. To achieve an accurate diagnosis, physicians should interpret the genetic report carefully along with clinical information and examinations. We described our experience with (1) clinical validation in patients with variants found using WES and (2) a diagnostic approach for those with negative findings from WES. METHODS WES was performed on patients with the clinical impression of hereditary neuromuscular disorders. Information on clinical manifestations, neurological examination, electrodiagnostic studies, histopathology of muscle and nerve, and laboratory tests were collected. RESULTS Forty-one patients (Male/Female: 18/23, age of onset: 34.5±15.9) accepted WES and were categorized into four scenarios: (1) patients with a positive WES result, (2) patients with an inconclusive WES result but supporting clinical data, (3) negative findings from WES, but a final diagnosis after further work-up, and (4) undetermined etiology from WES and in further work-ups. The yield rate of the initial WES was 63.4% (26/41). Among these, seventeen patients had positive WES result, while the other nine patients had inconclusive WES result but supporting clinical data. Notably, in the fifteen patients with equivocal or negative findings from WES, four patients (26.7%) achieved a diagnosis after further workup: tumor-induced osteomalacia, metabolic myopathy with pathogenic variants in mitochondrial DNA, microsatellite expansion disease, and vasculitis-related neuropathy. The etiologies remained undetermined in eleven patients (myopathy: 7, neuropathy: 4) after WES and further workup. CONCLUSIONS It is essential to design genotype-guided molecular studies to correlate the identified variants with their clinical features. For patients who had negative findings from WES, acquired diseases, mitochondrial DNA disorders and microsatellite expansion diseases should be considered.

Abstract
Heterogeneous integration of monolayers is an emergent route of spatially combining materials with available platforms for unprecedented properties. A long-standing challenge along this route is to manipulate interfacial configurations of each unit in stacking architecture. A monolayer of transition metal dichalcogenides (TMDs) offers an embodiment of studying interface engineering of integrated systems because optoelectronic performances generally trade off with each other due to interfacial trap states. While ultrahigh photoresponsivity of TMDs phototransistors has been realized, a long response time commonly appears and hinders applications. Here, fundamental processes in excitation and relaxation of the photoresponse are studied and correlated with interfacial traps of the monolayer MoS2. A mechanism for the onset of saturation photocurrent and the reset behavior in the monolayer photodetector is illustrated based on device performances. Electrostatic passivation of interfacial traps is achieved with the bipolar gate pulse and significantly reduces the response time for photocurrent to reach saturated states. This work paves the way toward fast-speed and ultrahigh-gain devices of stacked two-dimensional monolayers.

Abstract
To improve the color conversion performance, we study the nanoscale-cavity effects on the emission efficiency of a colloidal quantum dot (QD) and the Förster resonance energy transfer (FRET) from quantum well (QW) into QD in a GaN porous structure (PS). For this study, we insert green-emitting QD (GQD) and red-emitting QD (RQD) into the fabricated PSs in a GaN template and a blue-emitting QW template, and investigate the behaviors of the photoluminescence (PL) decay times and the intensity ratios of blue, green, and red lights. In the PS samples fabricated on the GaN template, we observe the efficiency enhancements of QD emission and the FRET from GQD into RQD, when compared with the samples of surface QDs, which is attributed to the nanoscale-cavity effect. In the PS samples fabricated on the QW template, the FRET from QW into QD is also enhanced. The enhanced FRET and QD emission efficiencies in a PS result in an improved color conversion performance. Because of the anisotropic PS in the sample surface plane, the polarization dependencies of QD emission and FRET are observed.

Abstract
BACKGROUND We tested the hypothesis that overexpression of cellular-prion-protein in adipose-derived mesenchymal stem cells (PrPCOE-ADMSCs) effectively protected the kidney against ischemia-reperfusion (IR) injury in rat. METHODS Part I of cell culture was categorized into A1(ADMSCs)/A2(ADMSCs+p-Cresol)/A3(PrPCOE in ADMSCs)/A4 (PrPCOE in ADMSCs+p-Cresol). Part II of cell culture was divided into B1(ADMSCs)/B2[ADMSCs+lipopolysaccharide (LPS)]/B3(PrPCOE in ADMSCs)/B4(PrPCOE in ADMSCs+LPS). Sprague-Dawley (SD) rats (n = 50) were equally categorized into groups 1 (sham-operated-control)/2 (IR)/3 (IR+ADMSCs/6.0 × 105 equally divided into bilateral-renal arteries and 6.0 × 105 intravenous administration by 1 h after IR)/4 [IR+PrPCOE-ADMSCs (identical dosage administered as group 3)]/5 [IR+silencing PRNP -ADMSCs (identical dosage administered as group 3)], and kidneys were harvested post-day 3 IR injury. RESULTS Part I results demonstrated that the cell viability at 24/48/72 h, BrdU uptake/number of mitDNA/APT concentration/mitochondrial-cytochrome-C+ cells and the protein expressions of ki67/PrPC at 72 h-cell culturing were significantly higher in PrPCOE-ADMSCs than in ADMSCs (all P < 0.001). The protein expressions of oxidative-stress (NOX-1/NOX2/NOX4/oxidized protein)/mitochondrial-damaged (p22-phox/cytosolic-cytochrome-C)/inflammatory (p-NF-κB/IL-1ß/TNF-α/IL-6)/apoptotic (cleaved caspase-3/cleaved-PARP) biomarkers were lowest in A1/A3 and significantly higher in A2 than in A4 (all P < 0.001). Part II result showed that the protein expressions of inflammatory (p-NF-κB/IL-1ß/TNF-α/IL-6)/apoptotic (cleaved caspase-3/cleaved-PARP) biomarkers exhibited an identical pattern of part I among the groups (all P < 0.001). The protein expressions of inflammatory (p-NF-κB/IL-1ß/TNF-α/MMP-9)/oxidative-stress (NOX-1/NOX-2/oxidized-protein)/mitochondrial-damaged (cytosolic-cytochrome-C/p22-phox)/apoptotic (cleaved caspase-3/cleaved-PARP/mitochondrial-Bx)/autophagic (beclin-1/ratio of LC3B-II/LC3B-I)/fibrotic (Smad3/TGF-ß) biomarkers and kidney-injury-score/creatinine level were lowest in group 1, highest in group 2, significantly higher in group 5 than in groups 3/4 (all P < 0.0001). CONCLUSION PrPCOE in ADMSCs rejuvenated these cells and played a cardinal role on protecting the kidney against IR injury.

Abstract
BACKGROUND Hereditary neuromuscular diseases (NMDs) are a group of rare disorders, and the diagnosis of these diseases is a substantial burden for referral centers. Although next-generation sequencing (NGS) has identified a large number of genes associated with hereditary NMDs, the diagnostic rates still vary across centers. METHODS Patients with a suspected hereditary NMD were referred to neuromuscular specialists at the National Taiwan University Hospital. Molecular diagnoses were performed by employing a capture panel containing 194 genes associated with NMDs. RESULTS Among the 50 patients referred, 43 had a suspicion of myopathy, and seven had polyneuropathy. The overall diagnostic rate was 58%. Pathogenic variants in 19 genes were observed; the most frequent pathogenic variant found in this cohort (DYSF) was observed in only four patients, and 10 pathogenic variants were observed in one patient each. One case of motor neuron disease was clinically mistaken for myopathy. A positive family history increased the diagnostic rate (positive: 72.7% vs. negative: 56.3%). Fourteen patients with elevated plasma creatine kinase levels remained without a diagnosis. CONCLUSION The application of NGS in this single-center study proves the great diversity of hereditary NMDs. A capture panel is essential, but high-quality clinical and laboratory evaluations of patients are also indispensable.

Abstract
The external quantum efficiency of a high-Al content (>0.6) AlGaN deep-ultraviolet (DUV) light-emitting diode is typically below 1% in the sub-250 nm wavelength range. One of the main reasons for this low efficiency is the fundamental properties of high-Al content AlGaN comprising the transverse-magnetic (TM)-dominant emission and low light extraction due to the total internal reflection (TIR). This work demonstrates a truncated pyramid nanostructure with fine-tuned multiple facets in an (AlN)8/(GaN)2 digital alloy to achieve highly efficient DUV emission at 234 nm. By applying nanoimprint lithography, dry and wet etching, a hexagonal truncated pyramid nanohole structure is fabricated featuring multiple crystal facets of (0001), (10-13), and (20-21) planes. These fine-tuned multiple facets act as reflecting mirrors that can effectively modulate the light propagation and extraction patterns to overcome the TIR via multiple reflections and enhanced scattering. Consequently, significant light extraction enhancements of 5.6 times and 1.1 times for TM and transverse-electric emissions are achieved in the truncated pyramid nanohole structure, respectively. The total luminous intensity of this unique nanostructure is greatly increased by 191% compared to that of a conventional planar structure. The truncated pyramid AlN/GaN nanostructure with fine-tuned multiple facets used in this work provides a promising approach for realizing highly efficient sub-250 nm DUV light-emitting devices.

Abstract
OBJECTIVE To investigate the roles of inducible costimulatory molecules (ICOS) and related cytokines in the immune regulation of Echinococcus granulosus infections in mice. METHODS Eighty BALB/c mice (weight 18-22 g) were divided into the control and infection groups, of 40 animals in each group. E. granulosus infection was modeled in mice by intraperitoneal injection of 10 000 protoscoleces per mouse. Serum levels of aspartate aminotransferase (AST), alanine aminotransferase (ALT) and alkaline phosphatase (ALP) and peripheral interleukin-4 (IL-4) and IL-10 levels were measured 2, 8, 30, 60, 180 days post-infection. Mouse liver specimens were excised for hematoxylin-eosin (HE) staining and immunostaining, and ICOS expression was quantified in mouse liver specimens using quantitative real-time PCR (qPCR) assay. RESULTS There were no significant differences in serum ALT (F = 12.082, P < 0.05), AST (F = 6.347, P < 0.05) or ALP levels (F = 52.186, P < 0.05) in mice 2, 8, 30, 60 and 180 days post-infection with E. granulosus. The serum ALT levels were significantly higher in the infection group than in the control group 2 [(61.72 ± 9.89) vs. (50.65 ± 4.67)U/L, P < 0.05] and 30 days post-infection [(80.61 ± 23.71)vs.(67.75 ± 9.79)U/L, P < 0.05], and the serum ALT levels were significantly higher in the infection group than in the control group 2 [(181.06 ± 60.61) vs.(115.58 ± 17.66)U/L, P < 0.05] and 180 days post-infection [(137.84 ± 29.01) vs. (108.05 ± 10.33) U/L, P < 0.05], while greater serum ALP levels were measured in the infection group than in the control group 2 [(162.90 ± 21.04)vs.(64.54 ± 5.99)U/L, P < 0.05], 8[(176.36 ± 24.56) vs. (62.70 ± 9.21)U/L, P < 0.05] and 30 days post-infection [(138.86 ± 13.59) vs. (58.60 ± 5.28) U/L, P < 0.05]. A few inflammatory cells were seen in mouse liver in the infection group 30 days post-infection, and no apparent changes were found in the mouse hepatic structure 60 days post-infection. On day 180 post-infection, a large number of epithelium-like cells presented fibrotic growth in mouse liver in the cyst-infiltrating regions, with cuticula formation seen, and plenty of red cells were present in lesions and hepatocyte space. Positive ICOS expression was detected in mouse liver in the infection group, with ICOS-positive cells predominantly seen in the cytoplasm of the hepatocyte, and the ICOS expression increased over time. The relative ICOS mRNA expression was 2.732 ± 0.094 on day 180 post-infection, which was significantly greater than that on day 2 postinfection (0.746 ± 0.049). There were no significant differences in serum IL-4 or IL-10 levels at different time points after E. granulosus infections, while the serum IL-4 and IL-10 levels peaked in the infection group 180 days and 60 days post-infection, respectively. Higher serum IL-4 levels were measured in the infection group than in the control group 8 [(22.50 ± 3.24) vs. (5.82 ± 0.49) pg/mL, P < 0.05], 30 [(15.49 ± 4.73) vs. (5.10 ± 1.38) pg/mL, P < 0.05], 60 [(36.93 ± 6.14) vs. (4.13 ± 1.19) pg/mL, P < 0.05] and 180 days post-infection [(198.35 ± 0.70) vs. (4.19 ± 0.98) pg/mL, P < 0.05], and higher IL-10 levels were measured in the infection group than in the control group 2 [(4.84 ± 1.91) vs. (2.11 ± 1.03) pg/mL, P < 0.05], 8 [(44.72 ± 14.63) vs. (3.16 ± 0.60) pg/mL, P < 0.05], 30 [(25.47 ± 8.00) vs. (3.83 ± 1.87) pg/mL, P < 0.05], 60 [(187.16 ± 60.44) vs. (3.69 ± 1.05) pg/mL, P < 0.05] and 180 days post-infection [(85.40 ± 7.15) vs. (3.25 ± 0.93) pg/mL, P < 0.05]. CONCLUSIONS High ICOS expression is present in the liver of mice with E. granulosus infections. The positive ICOS expression and immune activation levels increase with the time of E. granulosus infections, leading to aggravation of hepatocyte injury caused by inflammation.

Abstract
The variation behaviors of the morphology, transmission, and sheet resistance of the surface Ag/AgO nano-network (NNW) structures fabricated under different illumination conditions and with different Ag deposition thicknesses and thermal annealing temperatures in forming initial Ag nanoparticles (NPs) are studied. Generally, an NNW structure with a smaller mesh size or a denser branch distribution has a lower transmission and a lower sheet resistance level. Under the fabrication condition of a broader illumination spectrum, a lower thermal annealing temperature, or a thicker Ag deposition, we can obtain an NNW structure of a smaller mesh size. The mesh size of an NNW structure is basically controlled by the seed density of Brownian tree (BT) at the beginning of light illumination. A BT seed can be formed through a stronger local localized surface plasmon resonance for accelerating Ag oxidation in a certain region. Once an Ag/AgO BT seed is formed, the surrounding Ag NPs are reorganized to form the branches of a BT. Multiple BTs are connected to form a large-area NNW structure, which can serve as a transparent conductor. Under the fabrication conditions of a broader illumination spectrum, 3 nm Ag deposition, and 100 °C thermal annealing, we can implement an NNW structure to achieve ∼1.15μm in mesh size, ∼90 Ω sq-1in sheet resistance, and 93%-77% in transmittance within the wavelength range between 370 and 700 nm.

Abstract
This study tested the hypothesis that valsartan (Val) and melatonin (Mel)-assisted adipose-derived mesenchymal stem cells (ADMSCs) preserved the residual renal function in chronic kidney disease (CKD) rat through promoting cellular-prior-protein (PrPC) to upregulate PI3K/Akt/mTOR signaling and cell proliferation. In vitro study demonstrated that as compared with CKD-derived-ADMSCs, Val/Mel/overexpression of PrPC-treated CKD derived-ADMSCs significantly upregulated cell proliferation and protein expressions of PrPC and phosphorylated (p)-PI3K/p-Akt/p-mTOR, and downregulated oxidative stress (all p < 0.001). Rats (n = 42) were categorized into group 1 (sham-operated-control), group 2 (CKD), group 3 (CKD + ADMSCs/1.2 ×106 cells) + Mel/20 mg/kg/day), group 4 (CKD + siRNA-PrPC-ADMSCs/1.2 ×106 cells), group 5 (CKD + ADMSCs/1.2 ×106 cells + Val/20 mg/kg/day) and group 6 (CKD + Val + Mel). By day 35, the kidney specimens were harvested and the result showed that the protein expression of PrPC was highest in group 1, lowest in groups 2/4 and significantly lower in group 6 than in groups 3/5, but it was similar in groups 3/5 (all p < 0.0001). The protein expressions of cell-stress-signaling (p-PI3K/p-Akt/p-mTOR) and cell-cycle activity (cyclin-D1/clyclin-E2/Cdk2/Cdk4) exhibited an identical pattern, whereas the protein expressions of oxidative-stress (NOX-1/NOX-2)/mitochondrial fission (PINK1/DRP1)/apoptosis (cleaved-capsase3/cleaved-PARP) and fibrosis (TFG-ß/Smad3) as well as creatinine/BUN levels, ratio of urine-protein to urine-creatine and kidney-injured score exhibited an opposite pattern of PrPC among the groups (all p < 0.0001). In conclusion, Mel/Val facilitated-ADMSCs preserved renal architecture and function in CKD rat through promoting PrPC to regulate the cell proliferation/oxidative-stress/cell-stress signalings.

Abstract
Objective Mutations in the colony‐stimulating factor 1 receptor gene (CSF1R) were identified as a cause of adult‐onset inherited leukoencephalopathy. The present study aims at investigating the frequency, clinical characteristics, and functional effects of CSF1R mutations in Taiwanese patients with adult‐onset leukoencephalopathy. Methods Mutational analysis of CSF1R was performed in 149 unrelated individuals with leukoencephalopathy by a targeted resequencing panel covering the entire coding regions of CSF1R. In vitro analysis of the CSF1‐induced autophosphorylation activities of mutant CSF1R proteins was conducted to assess the pathogenicity of the CSF1R mutations. Results Among the eight CSF1R variants identified in this study, five mutations led to a loss of CSF1‐induced autophosphorylation of CSF1R proteins. Four mutations (p.K586*, p.G589R, p.R777Q, and p.R782C) located within the tyrosine kinase domain of CSF1R, whereas the p.T79M mutation resided in the immunoglobulin‐like domain. The five patients carrying the CSF1R mutations developed cognitive decline at age 41, 43, 50, 79, and 86 years, respectively. Psychiatric symptoms and behavior changes were observed in four of the five patients. The executive function and processing speed were severely impaired at an early stage, and their cognitive function deteriorated rapidly within 3–4 years. Diffusion‐restricted lesions at the subcortical regions and bilateral corticospinal tracts were found in three patients. Interpretation CSF1R mutations account for 3.5% (5/149) of the adult‐onset leukoencephalopathy in Taiwan. CSF1R mutations outside the tyrosine kinase domain may also disturb the CSF1R function and lead to the clinical phenotype. Molecular functional validation is important to determine the pathogenicity of novel CSF1R variants.

Abstract
This study tested the hypothesis that Entresto (En) therapy protected the cardiomyocytes and heart function in cardiorenal syndrome (CRS) rats fed with high-protein diet (HPD) through regulating the oxidative-stress and Mfn2-mediated mitochondrial functional integrity. En (12.5 μM for the in-vitro study) protected the H9C2-cells against H2O2-induced cell apoptosis, whereas stepwise-increased H2O2 concentrations induced a significant increase in protein expressions of Mfn2/phosphorylated (p)-DRP1/mitochondrial-Bax in H9C2-cells. En downregulated H2O2-induced mitochondrial fission/upregulated mitochondrial fusion and deletion of Mfn2 gene (i.e., shMfn2) to significantly reduce H2O2-induced ROS production. En significantly suppressed and shMfn2 further significantly suppressed both H2O2-reduced mitochondrial-membrane potential and H2O2-induced ROS production/cell apoptosis/mitochondrial damage/mitochondrial-Bax released from mitochondria in H9C2 cells. En significantly reduced protein expressions of Mfn2 and p-DRP1. Additionally, En significantly suppressed and shMfn2 further significantly suppressed the protein expressions of mitochondrial-damaged (DRP1)/oxidative-stress (NOX-1/NOX-2)/apoptosis (mitochondrial-Bax/caspase-3/PARP)/autophagic (LC3B-II/LC3B-I) biomarkers (all p < 0.01). Rats were categorized into group 1 [sham-control + high-protein-diet (HPD)], group 2 (CRS + HPD) and group 3 (CRS+ HPD + En/100 mg/kg/day). By day 63 after CRS induction, the LVEF was significantly lower in group 3 and more significantly lower in group 2 than in group 1, whereas the protein expressions of oxidative-stress (NOX-1/NOX-2/p22phox/oxidized protein)/apoptotic (mitochondrial-Bax/caspase-3/PARP), fibrotic (Smad-3/TGF-ß), autophagic (Beclin-1/Atg5/ratio of LC3B-II/LC3B-I) and mitochondrial-damaged (DRP1/cyclophilin-D/cytosolic-cytochrome-C) biomarkers exhibited an opposite pattern of LVEF among the groups. Downregulation of Mfn2 by En or shMfn2 in cardiomyocytes avoided H2O2 damage and En improved the cardiac function in HPD-feeding CRS rat via adjusting Mfn2-mediated mitochondrial functional integrity.

Abstract
Acute kidney injury (AKI) is commonly encountered and causes high mortality in hospitalized patients; however, effective therapies for AKI have still not been established. Accordingly, we performed a rodent model with acute renal ischemia-reperfusion (IR) and tested the hypothesis that combined tacrolimus and melatonin therapy could be superior to either one for protecting the kidney against IR injury. Adult-male SD rat (n = 30) were equally categorized into group 1 (receiving laparotomy only), group 2 (IR treated by 3.0 cc/normal-saline), group 3 [IR + tacrolimus/0.5 mg/kg by intravenous administration at 30 minutes and at days 1/2/3 after IR], group 4 (IR + melatonin/50 mg/kg by intra-peritoneal administration at 30 minutes and 25 mg/kg at days 1/2/3 after IR] and group 5 (IR + tacrolimus +melatonin). By day 3 after IR, the creatinine/BUN levels and ratio of urine protein to urine creatinine were highest in group 2, lowest in group 1 and significantly lower in group 5 than in groups 3/4 (all P < .0001), but they did not differ between the groups 3/4. The protein expressions of oxidative-stress (p47phox/NOX-1/NOX-2/NOX-4), upstream (TLR4/MAL/MyD88/TRAF6/ASK1/MKK4/MKK7/NF-κB) and downstream (IL-6/INF-γ/MMP-9/IL-1ß) inflammatory signaling, MAPK-family-signaling cascades(ERK1/2, JNK/p38/c-JUN), apoptotic/autophagic (p53/caspase 3/mitochondrial-Bax, ratio of LC3B-II/LC3B-I), and mitochondrial-damaged (cyclophilin D/cytochrome C/DRP1) biomarkers, and the expressions of inflammatory-immune cells (F4/80, CD14/CD3/CD8) as well as the kidney injured score exhibited an identical pattern of creatinine level (all P < .0001). In conclusion, combined tacrolimus and melatonin therapy was better than either single one on protecting the kidney functional and anatomical integrity against IR injury through suppressing inflammation and the generation of oxidative stress.

Abstract
Background This study tested the hypothesis that combined melatonin (Mel) and adipose-derived mesenchymal stem cells (ADMSCs) treatment was superior to either one alone on protecting the testis against acute testicular torsion-induced ischemia-reperfusion (TTIR) injury. Methods and results Male adult SD rats (n = 30) were equally categorized into group 1 (sham-operated control), group 2 [TTIR/by torsion of right/left testis (i.e., ischemia) with rotated 720° counterclockwise for 2 h, then detorsion (i.e., reperfusion) to the original position for 72 h], group 3 (TTIR + Mel/intraperitoneal administration/50 mg/kg at 30 min after ischemia, followed by 20 mg at 3 h and days 1/2/3 after TTIR), group 4 (TTIR + ADMSCs/1.2 × 106 cells/by tail-vein administration at 30 min after ischemia, followed by days 1/2 TTIR), and group 5 (TTIR + Mel + ADMSCs/tail-vein administration). The result showed that the protein expressions of oxidative-stress (NOX-1/NOX-2/oxidized-protein), apoptotic/mitochondrial-damaged (mitochondrial-Bax/cleaved-caspase3/cleaved-PARP/cytosolic-cytochrome C), and fibrotic (TGF-ß/Smad3) biomarkers as well as testicular damage scores were lowest in group 1, highest in group 2, and significantly higher in groups 3/4 than in group 5, but they showed no difference between groups 3/4, whereas the protein expressions of androgen receptor (AR) and vimentin showed an opposite pattern of oxidative stress (all p < 0.0001). The cellular levels of inflammation (MMP-9/MPO/CD68) exhibited an identical pattern, whereas the numbers of Sertoli cells, α-tubulin, AR and vimentin as well as thickness of seminiferous tubule exhibited an opposite pattern of oxidative stress among the groups (all p < 0.0001). Conclusion Mel-ADMSCs effectively protected the testis against TTIR injury.

Abstract
This study tested the hypothesis that therapy with double overexpression of miR‐19a‐3p and miR‐20a‐5p (miRDOE) to human inducible pluripotent stem cell–derived mesenchymal stem cells (iPS‐MSCs) was superior to iPS‐MSCs alone for preserving renal function in rat with pre‐existing chronic kidney disease (CKD), followed by ischaemia‐reperfusion (IR) injury. In vitro study demonstrated that the protein expressions of oxidative stress (NOX‐1/NOX‐2/NOX4/oxidized protein/p22phox), inflammatory downstream signalling (TLR2&4/MyD88/TRAF6/IKK‐ß/p‐NFκB/IL‐1ß/IL‐6/MMP‐9) and cell apoptosis/death signalling (cleaved caspase‐3/mitochondrial Bax/p‐ERKs/p‐JNK/p‐p38) at time‐points of 24‐hour/48‐hour cell cultures were significantly increased in p‐Cresol‐treated NRK‐52E cells than in the control that was significantly reversed by miR‐19a‐3p‐transfected iPS‐MSC (all P < .001). Animals were categorized into group 1 (sham‐operated control), group 2 (CKD‐IR), group 3 (CKD‐IR + oligo‐miRDOE of iPS‐MSCs/6.0 ×105/intra‐renal artery transfusion/3 hours after IR procedure), group 4 (CKD‐IR + iPS‐MSCs) and group 5 (CKD‐IR + miRDOE of iPS‐MSCs/6.0 ×105/intra‐renal artery transfusion/3 hour after IR procedure). By day 35, the creatinine/BUN levels were lowest in group 1, highest in group 2 and significantly lower in group 5 than in groups 3 and 4 (all P < .0001) but they showed no difference between the latter two groups. The protein expressions of oxidative stress, inflammatory downstream signalling and cell apoptosis/death signalling exhibited an identical pattern of creatinine level among the five groups (all P < .00001). Also, the microscopic findings demonstrated that the kidney injury score/fibrotic area/number of inflammatory cells (CD14+/CD68+) exhibited an identical pattern of creatine level (all P < .0001). The miRDOE of iPS‐MSCs was superior to iPS‐MSCs for preserving the residual kidney function and architecture in CKD‐IR rat.

Abstract
Glycosylation is important for biological functions of proteins and greatly affected by diseases. Exploring the glycosylation profile of the protein-specific glycosylation and/or the site-specific glycosylation may help understand disease etiology, differentiate diseases, and ultimately develop therapeutics. Patients with multiple sclerosis (MS) and patients with neuromyelitis optica spectrum disorder (NMOSD) are sometimes difficult to differentiate due to the similarity in their clinical symptoms. The disease-related glycosylation profiles of MS and NMOSD have not yet been well studied. Here, we analyzed site-specific glycan profiles of serum proteins of these patients by using a recently developed mass spectrometry technique. A total of 286 glycopeptides from 49 serum glycoproteins were quantified and compared between healthy controls (n = 6), remitting MS (n = 45) and remitting NMOSD (n = 23) patients. Significant differences in the levels of site-specific N-glycans on inflammation-associated components [IgM, IgG1, IgG2, complement components 8b (CO8B), attractin], central nerve system-damage-related serum proteins [apolipoprotein D (APOD), alpha-1-antitrypsin, plasma kallikrein and ADAMTS-like protein 3] were observed among three study groups. We furthered demonstrated that site-specific N-glycans on APOD on site 98, CO8B on sites 243 and 553 are potential markers to differentiate MS from NMOSD with an area under receiver operating curve value greater than 0.75. All these observations indicate that remitting MS or NMOSD patients possess a unique disease-associated glyco-signature in their serum proteins. We conclude that monitoring one's serum protein glycan profile using this high-throughput analysis may provide an additional diagnostic criterion for differentiating diseases, monitoring disease status and estimating response-to-treatment effect.

Abstract
RATIONALE & OBJECTIVE Hemodialysis facilities are high-risk environments for the spread of hepatitis C virus (HCV). Eliminating HCV from all dialysis facilities in a community may be achieved more effectively under a collaborative care model. STUDY DESIGN Quality improvement study of multidisciplinary collaborative care teams including nephrologists, gastroenterologists, and public health practitioners. SETTING & PARTICIPANTS All dialysis patients in Changhua County, Taiwan were treated using an interdisciplinary collaborative care model implemented within a broader Changhua-Integrated Program to Stop HCV Infection (CHIPS-C). QUALITY IMPROVEMENT ACTIVITIES Provision of an HCV care cascade to fill 3 gaps, including screening and testing, diagnosis, and universal direct-acting antiviral (DAA) treatment implemented by collaborating teams of dialysis practitioners and gastroenterologists working under auspices of Changhua Public Health Bureau. OUTCOME Outcome measures included quality indicators pertaining to 6 steps in HCV care ranging from HCV screening to treatment completion to cure. ANALYTICAL APPROACH A descriptive analysis. RESULTS A total of 3,657 patients from 31 dialysis facilities were enrolled. All patients completed HCV screening. The DAA treatment initiation rate and completion rate were 88.9% and 94.0%, respectively. The collaborative care model achieved a cure rate of 166 (96.0%) of 173 patients. No virologic failure occurred. The cumulative treatment ratios for patients with chronic HCV infection increased from 5.3% before interferon-based therapy (2017) to 25.6% after restricted provision of DAA (2017-2018), and then to 89.1% after universal access to DAA (2019). LIMITATIONS Unclear impact of this collaborative care program on incident dialysis patients entering dialysis facilities each year and on patients with earlier stages of chronic kidney disease. CONCLUSIONS A collaborative care model in Taiwan increased the rates of diagnosis and treatment for HCV in dialysis facilities to levels near those established by the World Health Organization.

Abstract
Rhodamine 6G (R6G) molecules linked CdZnSeS/ZnS green-emitting quantum dots (QDs) are self-assembled onto Ag nanoparticles (NPs) for studying the surface plasmon (SP) coupling effect on the Förster resonance energy transfer (FRET) process from QD into R6G. SP coupling can enhance the emission efficiency of QD such that FRET has to compete with QD emission for transferring energy into R6G. It is found that FRET efficiency is reduced under the SP coupling condition. Although R6G emission efficiency can also be enhanced through SP coupling when it is directly linked onto Ag NP, the enhancement decreases when R6G is linked onto QD and then the QD-R6G complex is self-assembled onto Ag NP. In particular, R6G emission efficiency can be reduced through SP coupling when the number of R6G molecules linked onto a QD is high. A rate-equation model is built for resembling the measured photoluminescence decay profiles and providing us with more detailed explanations for the observed FRET and SP coupling behaviors.

Abstract
By forming nanodisk (ND) structures on a blue-emitting InGaN/GaN quantum-well (QW) template, the QWs become close to the red-emitting quantum dots (QDs) and Ag nanoparticles (NPs) attached onto the sidewalls of the NDs such that Förster resonance energy transfer (FRET) and surface plasmon (SP) coupling can occur to enhance the efficiency of blue-to-red color conversion. With a larger ND height, more QWs are exposed to open air on the sidewall for more QD/Ag NP attachment through QD self-assembly and Ag NP drop casting such that the FRET and SP coupling effects, and hence the color conversion efficiency can be enhanced. A stronger FRET process leads to a longer QD photoluminescence (PL) decay time and a shorter QW PL decay time. It is shown that SP coupling can enhance the FRET efficiency.

Abstract
BACKGROUND Endothelial cell dysfunction plays the crucial role in initiation and propagation of obstructive arteriosclerosis which ultimately causes arterial obstructive syndrome. Additionally, severe endothelial progenitor cells (EPC) dysfunction is always found in those of end-stage renal disease (ESRD) patients. This study tested the hypothesis that a novel method, named "quality and quantity (QQ) culture", could successfully improve the EPC proliferation and function in ESRD patients. MATERIALS AND METHODS Peripheral blood mononuclear cells (PBMNCs) were isolated from age-matched control subjects (i.e., normal renal function) (group 1) and ESRD patients (group 2), followed by culture in either conventional EPC culture for one month or in QQ culture for 7 days, respectively. The result showed that as compared to the conventional EPC culture method, the EPC population and M2-like population/ratio (M2/M1) were significantly enriched in QQ culture both in groups 1 and 2 (all p < 0.001), but these parameters did not differ between the groups. As compared with conventional EPC culture, the angiogenesis capacity and colony formation were significantly increased in QQ culture (all p < 0.001), but they showed no difference between groups 1 and 2. In RAW264.7 macrophages treated by liposaccharide, the gene expressions and ELISA findings of pro-inflammatory cytokines (IL-1β/IL-6/TGF-β) and inflammatory mediator (iNOS) were significantly reduced in QQ culture than in conventional EPC culture in groups 1 and 2 (all p < 0.001), but they showed no difference between the groups. CONCLUSIONS This study demonstrated that QQ culture enhanced number, proliferation, and angiogenesis of EPCs and anti-inflammatory capacity in ESRD patients.

Abstract
Förster resonance energy transfer (FRET) from a green-emitting quantum dot (GQD) into a red-emitting quantum dot (RQD) is an important mechanism in a multiple-color conversion process, particularly under the surface plasmon (SP) coupling condition for enhancing color conversion efficiency. Here, the dependencies of FRET efficiency on the relative concentrations of GQD and RQD in their mixtures and their surface molecule coatings for controlling surface charges are studied. Also, the SP coupling effects induced by two kinds of Ag nanoparticles on the emission behaviors of GQD and RQD are demonstrated, particularly when FRET is involved in the coupling process. FRET efficiency is reduced under the SP coupling condition. SP coupling can enhance the color conversion efficiency of either GQD or RQD. The combination of SP coupling and FRET can be used for controlling the relative converted light intensities in a multiple-color conversion process.

Abstract
Peritoneal dialysis (PD) possesses multiple advantages for end stage renal disease. However, long-term PD triggers peritoneal fibrosis (PF). From the nationwide analysis of diabetic PD patients (n = 19,828), we identified the incidence of PD failure was significantly lower in diabetic patients treated with dipeptidyl peptidase 4 (DPP4) inhibitors. Experimental study further showed high concentration of glucose remarkably enhanced DPP4 to promote epithelial-mesenchymal transition (EMT) in the mesothelial cells. In chlorhexidine gluconate (CG)-induced PF model of rats, DPP4 expression was enriched at thickening peritoneum. Moreover, as to CG-induced PF model, DPP4 deficiency (F344/DuCrlCrlj strain), sitagliptin and exendin-4 treatments significantly inhibited DPP4 to reverse the EMT process, angiogenesis, oxidative stress, and inflammation, resulting in the protection from PF, preservation of peritoneum and the corresponding functional integrity. Furthermore, DPP4 activity was significantly correlated with peritoneal dysfunction. Taken together, DPP4 caused peritoneal dysfunction/PF, whereas inhibition of DPP4 protected the PD patients against PD failure.

Abstract
This study tested the hypothesis that uremic-toxic substances play a crucial role in enhancing left-common carotid artery (LCCA) stenosis after balloon-denudation of LCCA endothelium (BDLCCAE), and that the adventitial layer plays a complementary role in worsening LCCA stenosis. In vitro results showed the protein expressions of inflammation (IL-1β/TNF-α/IL-6), apoptosis (mitochondrial-Bax/cleaved-caspase-3/cleaved-PARP) and autophagy (beclin/Atg5/LC3B-II to LC3B-I ratio) as well as protein (NOX-1/NOX-2/p22phox/oxidized-protein), total cellular (H2DCFDA) and mitochondrial (Mitosox) levels of oxidative stress were significantly increased in p-Cresol-treated umbilical vein endothelial cells (HUVECs) as compared with control, whereas angiogenesis capacity (i.e., Matrigel-assay for HUVECs) exhibited an opposite pattern to inflammation between the two groups (all P < 0.001). Animals (n = 60) were categorized into group 1 (sham-operated control), group 2 (BDLCCAE), group 3 [BDLCCAE + ESRD patient's serum (1 cc/injection into deprived CA adventitia)], group 4 [BDLCCAE + ESRD patient's serum (1 cc/injection from peri-adventitia)], and group 5 [BDLCCAE + ESRD patient's serum (2 cc/by intravenous injection at days 1/3/7/10/14 after BDLCCADE)] and LCCA was harvested by day-21 after BDLCCAE procedure. Nitric-oxide release from LCCA and the LCCA cross-section area significantly and progressively reduced, whereas intimal and medial layers of LCCA significantly and progressively increased from groups 1 to 5 (all P < 0.001). The cellular expressions of inflammation (CD14+) and DNA-damage biomarker (γ-H2AX+) were significantly and progressively increased, whereas endothelial surface markers (CXCR4/vWF+) were significantly and progressively reduced from groups 1 to 5 (all P < 0.0001). Uremic toxins played an essential role in LCCA remodeling and obstruction. LCCA adventitia facilitated the initiation and propagation of LCCA proliferative obstruction.

Abstract
We introduce a single-grain gate-all-around (GAA) Si nanowire (NW) FET using the location-controlled-grain technique and several innovative low-thermal budget processes, including green nanosecond laser crystallization, far-infrared laser annealing, and hybrid laser-assisted salicidation, that keep the substrate temperature (Tsub) lower than 400 °C for monolithic three-dimensional integrated circuits (3D-ICs). The detailed process verification of a low-defect GAA nanowire and electrical characteristics were investigated in this article. The GAA Si NW FETs, which were intentionally fabricated within the controlled Si grain, exhibit a steeper subthreshold swing (S.S.) of about 65 mV/dec., higher driving currents of 327 µA/µm (n-type) and 297 µA/µm (p-type) @ Vth ± 0.8 V, and higher Ion/Ioff (>105 @|Vd| = 1 V) and have a narrower electrical property distribution. In addition, the proposed Si NW FETs with a GAA structure were found to be less sensitive to Vth roll-off and S.S. degradation compared to the omega(Ω)-gate Si FETs. It enables ultrahigh-density sequentially stackable integrated circuits with superior performance and low power consumption for future mobile and neuromorphic applications.

Abstract
BACKGROUND This study tested the hypothesis that combined hyperbaric oxygen (HBO) and autologous adipose-derived mesenchymal stem cell (ADMSC) therapy was superior to either alone at protecting renal function in rodents after acute ischemia-reperfusion (IR) injury. METHODS AND RESULTS Adult-male SD rats (n = 40) were equally categorized: group 1 (sham-operated control); group 2 (IR + 50 μg medium intra-renal artery administration); group 3 [IR + HBO (at 1.5 h and days 1 and 2 after IR)]; group 4 [IR + ADMSC (2.0×106 cells/5.0×105/per each renal artery and 1.0×106 by intravenous injection at 1.5 h after IR]; and group 5 (IR + HBO-ADMSC). By 72 hr after IR, the circulating levels of BUN/creatinine and ratio of urine protein/creatinine were significantly highest in group 2, lowest in group 1, significantly increased in group 5 than in groups 3 and 4, but not different between latter two groups, whereas the circulating levels of EPCs and soluble-angiogenesis biomarkers (SDF-1α/HIF-1α) exhibited an opposite pattern to BUN/creatinine among the five groups (all P<0.001). The kidney injury score, ROS (fluorescent intensity of H2DCFDA dye in kidney), inflammation (F4/80+, CD14+ cells) and glomerular-tubular injury score (WT-1/KIM-1) displayed an identical pattern whereas the integrity of podocyte components exhibited an opposite pattern to BUN/creatinine among the five groups (all P<0.0001). The protein expressions of inflammatory (MMP-9/TNF-α/NF-κB/ICAM-1), oxidative-stress (NOX-1/NOx-2/oxidized protein) and apoptotic (mitochondrial-Bax/cleaved-caspase3/PARP) markers showed an identical pattern to BUN/creatinine (all P<0.001). CONCLUSION Combined ADMSC-HBO therapy was superior to either one alone at protecting the kidney from acute IR injury.

Abstract
Increased circulating level of uraemic solute p‐cresyl sulphate (PCS) in patients with chronic kidney disease (CKD) is known to increase myocardial burden relevant to mitochondrial abnormalities. This study aimed at investigating mitochondrial response to PCS in H9C2 cardiomyoblasts. H9C2 cardiomyoblasts were treated with four different concentrations of PCS (3.125, 6.25, 12.5 and 25.0 µg/mL) to study the changes in cell proliferation, cell size and mitochondrial parameters including morphology, respiration, biogenesis and membrane potential. The lowest effective dose of PCS (6.25 µg/mL) induced mitochondrial hyperfusion with enhanced mitochondrial connectivity, mitochondrial oxygen consumption rates, mitochondrial mass, mitochondrial DNA copy number and increased volume of cardiomyoblasts. After PCS treatment, phosphorylation of energy‐sensing adenosine monophosphate‐activated protein kinase (AMPK) was increased without induction of apoptosis. In contrast, mitochondrial mass was recovered after AMPK silencing. Additionally, mitochondrial hyperfusion and cell volume were reversed after cessation of PCS treatment. The results of the present study showed that low‐level PCS not only caused AMPK‐dependent mitochondrial hyperfusion but also induced cell enlargement in H9C2 cardiomyoblasts in vitro.

Abstract
The plasmonic Dicke effect means a cooperative emission mechanism of multiple light emitters when they are simultaneously coupled with the same surface plasmon (SP) mode of a metal nanostructure to achieve a higher collective emission efficiency. Here, we compare the enhancements of emission efficiency among a series of SP-coupled InGaN/GaN quantum-well (QW) structures of different QW period numbers to show an emission behavior consistent with the plasmonic Dicke effect. The relative enhancement of overall emission efficiency increases with QW period number until it reaches a critical value, beyond which the enhancement starts to decrease. This critical QW period number corresponds to the effective depth range of the plasmonic Dicke effect in a multiple-QW system. It also represents an optimized QW structure for maximizing the SP coupling effect. Internal quantum efficiency and time-resolved photoluminescence are measured for comparing the enhanced emission efficiencies of blue and green QW structures with different QW period numbers through SP coupling induced by surface Ag nanoparticles.

Abstract
To improve the color-conversion efficiency based on a quantum-well (QW) light-emitting diode (LED), a more energy-saving strategy is needed to increase the energy transfer efficiency from the electrical input power of the LED into the emission of over-coated color-converter, not just from LED emission into converted light. In this regard, the efficiency of energy transfer of any mechanism from LED QW into the color-converter is an important issue. By overlaying blue-emitting QW structures and GaN templates with both deposited metal nanoparticles (DMNPs) and color-converting quantum dot (QD) linked synthesized metal nanoparticles (SMNPs) of different localized surface plasmon (LSP) resonance wavelengths for producing multiple surface plasmon (SP) coupling mechanisms with the QW and QD, we study the enhancement variations of their internal quantum efficiencies and photoluminescence decay times. By comparing the QD emission efficiencies between the samples with and without QW, one can observe the advantageous effect of QW coupling with LSP resonances on QD emission efficiency. Also, with the LSP resonance wavelengths of both DMNPs and SMNPs close to the QW emission wavelength for producing strong SP coupling with the QW and hence QD absorption, a higher QD emission or color-conversion efficiency can be obtained.

Abstract
Background This was a randomized, open‐label, controlled phase II clinical trial to investigate the safety, efficacy, and outcomes of intrarenal artery infusion of autologous peripheral‐blood‐derived CD34+ cells for patients with chronic kidney disease (CKD; ie, stage III or IV). Materials and Methods Between October 2016 and July 2018, 52 consecutive patients with CKD at stage III or IV were randomly allocated into a treatment group (TG; 2.5 × 107 cells for each intrarenal artery; n = 26) and a control group (CG; standardized pharmacotherapy only; n = 26). The primary endpoints included safety and change of creatinine level/creatinine clearance. The secondary endpoints were 12‐month combined unfavorable clinical outcomes (defined as dialysis or death), improvement in proteinuria, and CD34+ cell‐related adverse events. Results All patients were uneventfully discharged after CD34+ cell therapy. The baseline endothelial progenitor cell (EPC) populations did not differ between TG and CG (P > .5). Flow cytometric analysis showed increases in circulating EPC (ie, CD34+KDR+CD45dim/ CD34+CD133+CD45dim/CD31+CD133+CD45dim/CD34+CD133+KDR+/CD133+) and hematopoietic stem cell (CD34+) populations after granulocyte‐colony stimulating factor treatment (all P < .001). Besides, Matrigel assay of angiogenesis was also significantly enhanced (all P < .001). Renal‐venous blood samplings (ie, at 0, 5, 10, and 30 minutes after CD34+ cell infusion) demonstrated significant progressive increases in EPC level (P for trend <.001) among the TG patients. One‐year combined unfavorable clinical outcomes were significantly lower in TG than those in CG (0% [0] vs 13.3% [4], P = .038). By 12 months after CD34+ cell therapy, circulating creatinine level, ratio of urine protein to urine creatinine, and creatinine clearance showed no difference between TG and CG (all P > .1). Conclusion CD34+ cell therapy was safe and improved 1‐year outcome.

Abstract
BACKGROUND This study tested the long-term effect of extracorporeal shock wave (ECSW) therapy on ameliorating radiotherapy-induced chronic cystitis (CC) in rat. METHODS AND RESULTS Adult-female SD rats (n = 24) were equally categorized into group 1 (normal control), group 2 (CC induced by radiotherapy with 450 cGy twice with a four-hour interval to the urinary bladder), group 3 [CC with ECSW treatment (0.1 mJ/mm2/120 impulses once every 3 days after radiotherapy)]. Bladder specimens were harvested by day 60 after radiotherapy. By day 60, the degree of detrusor contraction was significantly reduced in group 2 than groups 1 and 3, and significantly reduced in group 3 than in group 1 (P < 0.0001). Number of WBC, occulted blood and bacteria were significantly higher in group 2 than in groups 1 and 3 (P < 0.01), but they showed no difference between the latter two groups (P > 0.3). The protein expressions of oxidative stress (NOX-1/NOX-2/oxidized protein), apoptosis (cleaved-caspase-3/cleaved-PARP), DNA-damaged marker (γ-H2AX), fibrosis (TGF-β/Smad3) and inflammatory signaling (TLR-4/MYD88/Mal/TRAF6/p-IκBα/p-NFκB/TNF-α/MMP-9/COX-2) were significantly higher in group 2 than in group 1, and were significantly reduced in group 3 (all P < 0.001). The cellular expressions of inflammatory (CD14+/CD68+/MIF+/MMP-9), immunoreactive (CD4+/CD8+) and cytokeratin (CK17/CK18) biomarkers, and collagen-deposition/fibrotic areas as well as bladder-damaged score/disruption of the bladder mucosa displayed an identical pattern compared to that of oxidative stress among the three groups (all P < 0.0001). CONCLUSION The long-term effect of ECSW treatment was reliable on protecting the urinary bladder from radiation-induced CC.

Abstract
Based on the experimentally demonstrated In content distribution in the InGaN/GaN quantum wells on a two-section GaN nanorod (NR) sidewall, a white-light light-emitting diode (LED) without phosphor is designed and simulated. Following the dependencies of the In diffusion length and incorporation ratio on NR geometric variables of a theoretical model, the height, radius, and tapering section geometry of the GaN NR are designed for controlling the relative intensities of a blue and a yellow emission component to mix into white light. The higher-In upper section of the NR is first excited to emit a relatively stronger yellow component when injection current is low. As the injection current increases, more current spreads into the lower-In lower section, eventually leading to a stronger blue emission component. The proposed NR LED structure provides an alternative solution for phosphor-free white-light generation.

Abstract
With two different residual surfactants, four different metal nanoparticles (NPs), including two Au NPs and two Ag NPs are synthesized for linking with red-emitting CdZnSeS/ZnS colloidal quantum dots (QDs) to enhance QD emission efficiency. Those metal NPs are first connected with amino polyethylene glycol thiol of different molecular weights to avoid aggregation and make them positively charged. They can attract negatively charged QDs for inducing surface plasmon (SP) coupling such that either QD absorption or emission and hence overall color conversion efficiency can be enhanced. The enhancement of QD emission efficiency is evaluated through the comparison of time-resolved photoluminescence behaviors under different QD linkage conditions. Such results are confirmed by the measurement of the emission quantum efficiency of QD. It is found that by linking QDs onto Ag NPs, the QD emission efficiency is more enhanced, when compared with Au NPs. Also, depending on the synthesis process, the residual surfactant of citrate leads to a relatively large increment in QD emission efficiency, when compared to the surfactant of cetrimonium chloride. A more enhanced QD emission efficiency is caused by a higher QD linkage capability and a stronger SP coupling effect.

Abstract
This study traced intravenously administered induced pluripotent stem cell (iPSC)‐derived mesenchymal stem cells (MSC) and assessed the impact of iPSC‐MSC on preserving renal function in SD rat after 5/6 nephrectomy. The results of in vitro study showed that FeraTrack™Direct contrast particles (ie intracellular magnetic labelling) in the iPSC‐MSC (ie iPS‐MSCSPIONs) were clearly identified by Prussian blue stain. Adult‐male SD rats (n = 40) were categorized into group 1 (SC), group 2 [SC + iPS‐MSCSPIONs (1.0 × 106cells)/intravenous administration post‐day‐14 CKD procedure], group 3 (CKD), group 4 [CKD + iPS‐MSCSPIONs (0.5 × 106cells)] and group 5 [CKD + iPS‐MSCSPIONs (1.0 × 106cells)]. By day‐15 after CKD induction, abdominal MRI demonstrated that iPS‐MSCSPIONs were only in the CKD parenchyma of groups 4 and 5. By day 60, the creatinine level/ratio of urine protein to urine creatinine/kidney injury score (by haematoxylin and eosin stain)/fibrotic area (Masson's trichrome stain)/IF microscopic finding of kidney injury molecule‐1 expression was lowest in groups 1 and 2, highest in group 3, and significantly higher in group 4 than in group 5, whereas IF microscopic findings of podocyte components (ZO‐1/synaptopodin) and protein levels of anti‐apoptosis ((Bad/Bcl‐xL/Bcl‐2) exhibited an opposite pattern to creatinine level among the five groups (all P < .0001). The protein expressions of cell‐proliferation signals (PI3K/p‐Akt/m‐TOR, p‐ERK1/2, FOXO1/GSK3β/p90RSK), apoptotic/DNA‐damage (Bax/caspases8‐10/cytosolic‐mitochondria) and inflammatory (TNF‐α/TNFR1/TRAF2/NF‐κB) biomarkers displayed an identical pattern to creatinine level among the five groups (all P < .0001). The iPS‐MSCSPIONs that were identified only in CKD parenchyma effectively protected the kidney against CKD injury.

Abstract
Low intrinsic conductivity and large volume expansion seriously restrict the efficient lithium storage performance of metal sulfides. Here, we fabricate a hybrid material of NiS2 nanoparticles/carbon nanohelmets (NiS2/CNHs) to address the above issues. As an anode material in lithium-ion batteries, NiS2/CNHs exhibit excellent cycling stability (490 mA h g-1 after 3000 cycles at 5 A g-1) and rate properties (412 mA h g-1 at 10 A g-1), outperforming other NiS x -based anode materials. These remarkable performances originate from the three-dimensional helmet-like integrated architecture of NiS2/CNHs, which reduces the electrode resistance due to the tight combination between NiS2 and CNHs, provides efficient diffusion paths for the electrolyte and Li+ owing to the amorphous nanoporous carbon structure, and significantly mitigates the aggregation and buffers the large volumetric expansion of NiS2 nanoparticles upon long-term cycling thanks to the open three-dimensional architecture and well-dispersed NiS2 nanoparticles on it.
