Abstract
BACKGROUND/AIM Given the characteristics of Serratia marcescens (S. marcescens), this study aimed at investigating its presence in the hands and contact lens cases of orthokeratology wearers, along with the status of bacterial contamination. PATIENTS AND METHODS The 39 patients received the questionnaires about the background of orthokeratology and hygiene habits. A total of 39 contact lens cases and 39 hand samples from the patients were collected at Show Chwan Memorial Hospital from June to August in 2020 and sent to National Chung Cheng University for DNA extraction and PCR identification. RESULTS The results indicated a detection rate of 5.13% for S. marcescens in the contact lens cases and 12.82% in the hand samples. Additionally, 66.67% of contact lens case samples and 30.77% of hand samples found positive for 16s bacterial amplicons. The relationship between hand contamination and the duration of contact lens usage were revealed for both S. marcescens (p=0.021) and 16s bacterial amplicons (p=0.048). CONCLUSION The results indicated that hand hygiene is more critical than focusing on contact lens hygiene when it comes to preventing S. marcescens infections. Nevertheless, both proper hand and contact lens hygiene practices can reduce the detection of bacterial eye pathogens, especially a common intestinal bacterium.

Abstract
With completing a baseline survey of a large natural population cohort, conducting regular follow-up has become a key factor in further improving the quality of cohort construction and ensuring its sustainable development. Typical cohort follow-up methods include repeat surveys, routine monitoring, and community-oriented surveillance. However, in practical applications, there are often issues such as high costs, difficulty, and high error rates. Telephone follow-up is an important supplementary method to the methods mentioned above, as it has the characteristics of low cost, fast response, and high quality. However, the with difficult organization, quality control is challenging, response rates are low, and management levels vary widely, which limits its widespread use in large-scale population cohort studies. Given the above problems, this study draws on customer relationship management based on the actual needs of the China Northwest Cohort follow-up. It relies on the REDCap electronic data collection platform to build a telephone follow-up management and quality control system. Targeted solutions are provided for key issues in telephone follow-up implementation, including organizational structure, project management, data collection, and process quality control, to improve the quality control level of telephone follow-up comprehensively and thereby enhance the quality and efficiency of follow-up. We hope to provide standardized follow-up programs and efficient quality control tools for newly established and existing cohort studies.

Abstract
PURPOSE/OBJECTIVE(S) Radioresistance is the main reason for nasopharyngeal carcinoma (NPC) recurrence leading to treatment failure, and inducing ferroptosis has gradually been a new way to enhance radiosensitivity. N6-methyladenosine (m6A) is involved in regulation of numerous biological processes. However, whether m6A affects ferroptosis in NPC is still unclear. In this study, we conducted a siRNA library screening to identify m6A reader YTHDC1 as an essential oncogene that suppressed ferroptosis and radiosensitivity by promoting SREBF1 mRNA nuclear export in nasopharyngeal carcinoma. MATERIALS/METHODS The expression and function of YTHDC1 were assessed via CCK8 cell viability assay, immunostaining, real-time PCR, western blot, radiation clonogenic assay and fluorescence in situ hybridization assay. Ferroptosis was determined by detecting cell viability, lipid peroxidation, abnormal mitochondrial and cell death rate. The in vivo effects of YTHDC1 were examined with RSL3 treatment or lentivirus modification of YTHDC1 expression in radiated mouse models. RESULTS Based on RSL3-induced ferroptotic cell death model and a siRNA library about m6A modification associated gene screening, we identified m6A reader YTHDC1 could inhibit ferroptosis as well as radiosensitivity of NPC, both in vivo and in vitro. Mechanistically, YTHDC1 protein could recognize m6A sites in the CDS region and 3' untranslated region (3'UTR) of SREBF1 mRNA and promote SREBF1 mRNA nuclear export, which finally resulted in transcriptional upregulation of genes key to ferroptosis such as SCD and FASN. Furthermore, the high expression of YTHDC1 was negatively regulated by ZNF598 via ubiquitination and associated with unfavorable survival in NPC patients due to radioresistance. CONCLUSION Our findings reveal the critical role of YTHDC1 specifically in inhibiting ferroptosis and radiosensitivity via m6A-dependent mechanism and provide an exploitable target and therapeutic strategy for overcoming radioresistance in NPC.

Abstract
OBJECTIVE This systematic review and meta-analysis aimed to assess the effects of repetitive transcranial magnetic stimulation and select a suitable protocol for poststroke visuospatial neglect. DESIGN PubMed, Cochrane Library, and Embase databases were searched for relevant studies from the inception date to October 31, 2021. The inclusion criteria were (1) randomized controlled trials, (2) people with visuospatial neglect, (3) treatment with different repetitive transcranial magnetic stimulation protocols, (4) comparison with sham or blank control, and (5) reports of performance measurements. RESULTS Data were obtained from 11 randomized controlled trials. The effects of immediate and 1-mo postintervention were measured using line bisection test, cancellation test, and Catherine Bergego Scale. Results showed statistically significant improvement when applying low-frequency (0.5-1 Hz) repetitive transcranial magnetic stimulation or continuous theta burst stimulation to the left hemisphere on short- and long-term line bisection test (standardized mean difference = -1.10, 95% confidence interval = -1.84 to -0.37; standardized mean difference = -1.25, 95% confidence interval = -2.11 to -0.39) and cancellation test (standardized mean difference = 1.08, 95% confidence interval = 0.45 to 1.71; standardized mean difference = 1.45, 95% confidence interval = 0.42, 2.47). CONCLUSIONS Repetitive transcranial magnetic stimulation may be considered a treatment option for poststroke visuospatial neglect. This review proves that a decrease in neuronal excitation in the left hemisphere, which restores the interhemispheric balance, benefits poststroke visuospatial neglect.

Abstract
Background and Objectives: In 2004, the Health Administration of Taiwan began to promote a hospital-based cancer screening quality improvement program, under the principle that "prevention is better than therapy". The aim of this study was to evaluate the effectiveness of colorectal cancer (CRC) screening in patients who received a fecal immunochemical test (FIT) at a hospital in central Taiwan. Materials and Methods: This was a retrospective study. Results: Fecal occult blood immunoassays for CRC screening were conducted in 58,891 participants, of whom 6533 were positive (positive detection rate 11.10%). The positive patients then underwent colonoscopy, and the detection rates of polyps and CRC accounted for 53.6% and 2.4% of all colonoscopy-confirmed diagnoses (3607), respectively. We further enrolled data from patients diagnosed with CRC at our hospital from 2010 to 2018. The patients with CRC were divided into two groups according to whether or not they had received fecal occult blood screening. Among the 88 patients with CRC by screening, 54 had detailed medical records including cancer stage. Of these 54 patients, 1 (1.8%) had pre-stage, 11 (20.4%) had stage I, 24 (44.4%) had stage II, 10 (18.5%) had stage III, and 8 (14.8%) had stage IV CRC. The early cancer detection rates of the screening and non-screening groups were 66.7% and 52.7%, respectively, and the difference was significant (p = 0.00130). Conclusions: In this study, screening with FIT significantly increased the early detection of CRC. The main advantage of FIT is the non-invasiveness and low cost. It is hoped that the further adoption of early screening can increase the detection rates of colorectal polyps or early cancer to improve survival, reduce the high cost of subsequent cancer treatment, and reduce the burden on the patient and healthcare system.

Abstract
Children with developmental coordination disorder (DCD) have been reported to have a higher risk of dyslexia than children with typical development (TD). Phonological awareness (PA) and rapid automatic naming (RAN) are known to be predictive of children's reading development. The present study examined PA and RAN in preschool children with and without probable DCD in Taiwan. In total, 704 children aged 5-6 years old from 25 preschools in Taichung City were included as participants. The probable DCD children performed more poorly than the children with TD on the PA and the RAN tests. Put in deficit terms, 22% of the children with TD, but 48% of the probable DCD children, had a single or dual PA/RAN deficit. Furthermore, it was manual dexterity that bore the unique relationship with RAN. Automatic visual perceptual-motor coordination may be the common processing component that underlies RAN and probable DCD. The early visual perceptual-motor profile of probable DCD children has not been well recognized before.

Abstract
RATIONALE Progressive encephalopathy with brain edema and/or leukoencephalopathy-1 is an infantile, lethal neurometabolic disorder caused by a NAD(P)HX epimerase (NAXE) gene mutation. It is characterized by a fluctuating disease course with repeated episodes of improvement and regression. In this report, we present a rare case of NAXE gene mutation-related encephalopathy with unexpected neurological recovery and long survival time. PATIENT CONCERNS A 20-month-old girl presented with progressively unsteady gait and bilateral hand tremors after a trivial febrile illness. Her disease rapidly progressed to consciousness disturbance, 4-limb weakness (muscle power: 1/5 on the Medical Research Council scale), and respiratory failure. The patient gradually recovered 2 months later. However, another episode of severe fever-induced encephalopathy developed 2 years after the initial presentation. DIAGNOSES Results of laboratory investigations, including complete blood count, blood chemistry, inflammatory markers, and cerebral spinal fluid analysis were unremarkable. Electroencephalography and nerve conduction velocity studies yielded normal results. Brain magnetic resonance imaging on diffusion-weighted imaging revealed abnormal sysmmetric hyperintensity in the bilateral middle cerebellar peduncles. A genetic study using whole exome sequencing confirmed the diagnosis of NAXE gene mutation-related encephalopathy. INTERVENTIONS Pulse therapy with methylprednisolone, intravenous immunoglobulin, coenzyme Q10, and carnitine were initially introduced. After a NAXE gene defect was detected, the vitamin B complex and coenzyme Q10 were administered. A continuous rehabilitation program was also implemented. OUTCOMES NAXE gene mutation-related encephalopathy is usually regarded as a lethal neurometabolic disorder. However, the outcome in this case is better than that in the previous cases. She showed progressive neurological recovery and a longer survival time. The muscle power of the 4 limbs recovered to grade 4. At present (age of 5.5 years old), she can walk with an unsteady gait and go to school. LESSONS Although NAXE gene mutation-related encephalopathy is rare, it should be considered as a differential diagnosis of early onset progressive encephalopathy.

Abstract
Aeromonas are found in various habitats, particularly in aquatic environments. This study examined the presence of the most common human pathogenic Aeromonas species (Aeromonas caviae, A. hydrophila, and A. veronii) in surface water, sea water, and shellfish. The detection rates in fishing harbour seawater, shellfish farming seawater, and a river basin were 33.3%, 26.4%, and 29.4%, respectively, and high prevalence was observed in summer. The detection rates in shellfish procured from a fish market and shellfish farm were 34.9% and 13.3%, respectively. The most abundant species of human pathogenic Aeromonas detected via water sampling was A. caviae, whereas that obtained via shellfish sampling was A. veronii. The prevalence of human pathogenic Aeromonas in river water was lower in fishing harbours and in the estuary shellfish farming area. Here, 25 isolates of human pathogenic Aeromonas species were isolated from 257 samples and divided among 16 virulence profiles. The high virulence gene-carrying isolates (more than six genes) belonged to A. hydrophila. The shellfish-sourced isolates had the highest detection rates of act, aerA, and fla genes than of other virulence genes, and vice versa for seawater-sourced isolates. The Aeromonas isolates showed high levels of resistance to ampicillin-sulbactam; however, none were resistant to cefepime, ciprofloxacin, or gentamicin. The incidence of multiple drug resistance (MDR) in Aeromonas isolates was 20%. In this study, phylogenetic analysis with 16S rRNA sequencing, biochemical tests and enterobacterial repetitive intergenic consensus-polymerase chain reaction fingerprinting facilitated the distinct categorisation of three species of human pathogenic Aeromonas isolates. In addition, A. veronii isolates from the same geographical area were also concentrated in the same cluster. This study provides information on the risk of infection by Aeromonas with MDR and multiple virulence genes isolated from shellfish and aquatic environments.

Abstract
Pathogen populations in estuarine areas are dynamic, as they are subject to multiple natural and anthropogenic challenges. Heavy rainfall events bring instability to the aquatic environment in estuaries, causing changes in pathogen populations and increased environmental sanitation and public health concerns. In this study, we investigated the effects of heavy precipitation on the occurrence of pathogens in the Puzi River estuary, which is adjacent to the largest inshore oyster farming area in Taiwan. Our results indicated that Vibrio parahaemolyticus and adenovirus were the most frequently detected pathogens in the area. There was a significant difference (Mann-Whitney U test, p < 0.01) in water quality parameters, including total coliform, Escherichia coli, water temperature, turbidity, salinity, and dissolved oxygen, between groups with and without V. parahaemolyticus. In addition, the detection rate was negatively correlated with the average daily rainfall (r2 > 0.8). There was no significant difference between water quality parameters and the presence/absence of adenovirus, but a positive correlation was observed between the average daily rainfall and the detection rate of adenovirus (r2 ≥ 0.75). We conclude that heavy precipitation changes estuarine water quality, causing variations in microbial composition, including pathogens. As extreme weather events become more frequent due to climate change, the potential impacts of severe weather events on estuarine environments require further investigation.

Abstract
Abstract
Purpose
Robot-assisted gait rehabilitation has been proposed as a plausible supplementary rehabilitation strategy in stroke rehabilitation in the last decade. However, its exact benefit over traditional rehabilitation remain sparse and unclear. It is therefore the purpose of the current study to comparatively investigate the clinical benefits of the additional robot-assisted training in acute stroke patients compared to standard hospital rehabilitation alone.
Methods
Ninety acute stroke patients (< 3 month) were recruited. All participants received the standard hospital neurorehabilitation comprises 45–60 min sessions daily for 3 weeks. Sixty patients also received an additional 30 min of robot-assisted gait training with the HIWIN MRG-P100 gait training system after each of the standard neurorehabilitation session. Outcome measures included: 1. Berg Balance Scale (BBS); 2. Brunnstrom Stage; 3. Pittsburgh Sleep Quality Index and 4. Taiwanese Depression Questionnaire (TDQ) which were assessed pre-treatment and then after every five training sessions.
Results
Both groups demonstrated significant improvement pre- and post-treatment for the BBS (robotic group p = 0.023; control group p = 0.033) but no significant difference (p > 0.1) between the groups were found. However, the robotic training group had more participants demonstrating larger BBS points of improvement as well as greater Brunnstrom stage of improvement, when compared to the control group. No significant within and between group statistical differences (p > 0.3) were found for Pittsburgh Sleep Quality Index and Taiwanese Depression Questionnaire.
Conclusion
The addition of robotic gait training on top of standard hospital neurorehabilitation for acute stroke patients appear to produce a slightly greater improvement in clinical functional outcomes, which is not transferred to psychological status.

Abstract
According to the operative characteristics, the stimulated site and the curative effect-emerged site of bloodletting therapy, its clinical characteristics may be divided into three categories: a) local stimulation induced focus-local effect, b) local stimulation induced effect of the distal target organ (point-to-point distal effect), and c) special point stimulation induced broader effect of the whole body. Accordingly, the underlying mechanisms of clinical outcomes mainly involve the improvement of the local microcirculation and secondary changes of inflammatory substances for the first category (local focus). The point-to-point distal effect might mainly involve the innervation of nerve segments, while the broad effect of specific acupoint stimulation might involve multiple levels of the neuro-endocrine-immune system. The future research on the mechanisms of bloodletting should starts from its specific effects and the type of disease, which should not be generalized.

Abstract
Objective: To evaluate the prognostic value of kinetic changes in minimal residual disease (MRD) status, as well as its relationship with risk stratification, therapeutic response and treatment in patients with newly-diagnosed multiple myeloma (MM) . Methods: A total of 135 patients with newly-diagnosed MM were screened, and 105 patients who achieved VGPR or more as the best responses were included into this study. The MRD status was determined by multiparameter flow cytometry (MFC) at multiple intervals after two cycles of treatment until clinical relapse, death, or last follow-up. The statistical methods included Kaplan-Meier analysis, Cox regression, etc. Results: ①In all 135 patients, 57.8% (78/135) patients achieved MRD negativity (MRD(-)) after treatment. In 105 patients who achieved VGPR and thus included in this study, the MRD(-) rate was 72.4% (76/105) , with a median interval of 3 months from starting treatment to achievement of MRD(-) status. ②The 2-year PFS rate of patients with MRD(-) status was significantly higher than that of MRD(+) status (62.2% vs 41.3%, P=0.001) , while MRD persistence (MRD(+)) was an independent factor for poor prognosis (multivariate analysis for PFS: P=0.044, HR=3.039, 95%CI 1.029-8.974) . ③Loss of MRD(-) status (i.e., MRD reappearance) showed inferior outcomes compared with MRD sustained negative ones, the PFS was 18 months versus not reach (P<0.001) and the OS was not reach for both (P=0.002) . ④The 2-year PFS and OS rates of patients with duration of MRD(-)status≥12 months were significantly higher than those of the control group (PFS: 77.7% vs 36.7%, P<0.001; OS: 96.4% vs 57.9%, P<0.001 respectively) . Duration of MRD(-) status was associated with a marked reduction in risk of relapse or death (univariate analysis for PFS: P<0.001, HR=0.865, 95%CI 0.815-0.918; for OS: P=0.001, HR=0.850, 95%CI 0.741-0.915 respectively) . ⑤Moreover, even in patients carrying high-risk cytogenetic abnormalities (CA) or ineligible for ASCT, MRD negativity remained its prognostic value to predict PFS (high-risk CA medianPFS: not reach vs 19 months, P=0.006; ineligible for ASCT medianPFS: not reach vs 25 months, P=0.052 respectively) . ⑥Last, treatment with the bortezomib-based regimens contributed to prolonged MRD(-) duration (median MRD(-) duratio: 25 months vs 10 months, P=0.034) . Conclusion: Our findings supported MRD(+) status as an independent poor prognostic factor in MM patients, which implicated that duration of MRD(-) status also played a significant role in evaluation of prognosis, while loss of MRD(-)status might serve as an early biomarker for relapse. Therefore, monitoring of MRD kinetics might more precisely predict prognosis, as well as guide treatment decision, especially for when to start retreatment in relapsed patients.

Abstract
Xanthomonads were detected by using the Xan-D(CCF) medium from the brassica seeds, and their pathogenicity was determined by plant inoculation tests. It was found that some seed lots were infested with Xanthomonas campestris pv. campestris, some with X. campestris pv. raphani, and some with nonpathogenic xanthomonads. The nonpathogenic xanthomonad strains were identified as X. campestris, and the multilocus sequence analysis showed that the nonpathogenic X. campestris strains were grouped together with pathogenic X. campestris, but not with nonpathogenic strains of X. arboricola. In addition, all isolated X. campestris pv. campestris and X. campestris pv. raphani strains were positive in the hrpF-PCR, but the nonpathogenic strains were negative. It was further found that nonpathogenic X. campestris strain nE1 does not contain the entire pathogenicity island (hrp gene cluster; type III secretion system) and all type III effector protein genes based on the whole genome sequence analyses. The nonpathogenic X. campestris strain nE1 could acquire the entire pathogenicity island from the endemic X. campestris pv. campestris and X. campestris pv. raphani strains by conjugation, but type III effector genes were not cotransferred. The studies showed that the nonpathogenic X. campestris strains indeed exist on the brassica seeds, but it could be differentiated by the PCR assays on the hrp and type III effector genes. Nevertheless, the nonpathogenic X. campestris strains cannot be ignored because they may be potential gene resources to increase genetic diversity in the endemic pathogenic X. campestris pv. campestris and X. campestris pv. raphani strains.

Abstract
We analyzed 2 batches of environmental samples after a microsporidial keratoconjunctivitis outbreak in Taiwan. Results indicated a transmission route from a parking lot to a foot washing pool to a swimming pool and suggested that accumulation of mud in the foot washing pool during the rainy season might be a risk factor.

Abstract
Objective: To evaluate the prognostic significance of combining ISS-Ⅲ and high risk cytogenetic abnormalities [HRCAs, including 1q gain/amplification and del (17p) ] in patients with newly-diagnosed multiple myeloma (NDMM) . Methods: The clinical characteristics and relevant variables were retrospectively analyzed in a total of 270 NDMM patients diagnosed between November 2009 and May 2018. ISS-Ⅲ stage and HRCAs [detected by FISH, including 1q gain/amplification and del (17p) ] were defined as risk factors (hit) . Based to the number of hit per case, these patients were divided into four groups carrying 0 to 3 risk factors, respectively. Progress-free survival (PFS) and overall survival (OS) were then analyzed using the Kaplan-Meier estimator. Results: Patients who carried single hit (n=120, 44.4%) had shorter median PFS (23.0 vs 28.9 months; P>0.05) and OS (42.3 vs 53.7 months; P>0.05) than those with no risk factors (n=66, 24.4%) . Of note, the outcome of patients who had two or more risk factors (double/triple, n=84, 31.1%) was much worse than those with either no or one risk factor, indicated by significantly reduced median PFS (14.5 months; HR=1.584, 95%CI 1.082-2.319; P=0.003 for double/triple vs single hit) and OS (18.4 months, HR=2.299, 95%CI 1.485-3.560; P<0.001 for double/triple vs single hit) . Strikingly, patients who had three risk factor (triple hit, n=5, 1.9%) displayed the poorest survival with extraordinarily shorter PFS (0.9-15.1 months) and OS (0.9-18.9 months) compared to those carrying two risk factors (double hit) . Analogous results were obtained when different combinations of ISS stages and HRCAs were analyzed. Conclusion: These results suggest a potential but rather important role of combining multiple (e.g. double or triple) adverse factors determined via the routine ISS staging and FISH detection of cytogenetic abnormalities in risk stratification and prognostic prediction, which might be helpful to identify high risk patients more precisely at diagnosis. It also raised a possibility that a small group of ISS-Ⅲ patients carrying both 1q gain/amplification and del (17p) might represent an "extremely-high risk" subset of MM.

Abstract
Drug resistance is the main obstacle in the improvement of chemotherapeutic efficacy in glioblastoma. Previously, we showed that dehydroepiandrosterone (DHEA), one kind of androgen/neurosteroid, potentiates glioblastoma to acquire resistance through attenuating DNA damage. Androgen receptor (AR) activated by DHEA or other types of androgen was reported to promote drug resistance in prostate cancer. However, in DHEA-enriched microenvironment, the role of AR in acquiring resistance of glioblastoma remains unknown. In this study, we found that AR expression is significantly correlated with poor prognosis, and AR obviously induced the resistance to temozolomide (TMZ) treatment. Herein, we observed that ALZ003, a curcumin analog, induces FBXL2-mediated AR ubiquitination, leading to degradation. Importantly, ALZ003 significantly inhibited the survival of TMZ-sensitive and -resistant glioblastoma in vitro and in vivo. The accumulation of reactive oxygen species (ROS), lipid peroxidation and suppression of glutathione peroxidase (GPX) 4, which are characteristics of ferroptosis, were observed in glioblastoma cell after treatment of ALZ003. Furthermore, overexpression of AR prevented ferroptosis in the presence of GPX4. To evaluate the therapeutic effect in vivo, we transplanted TMZ-sensitive or -resistant U87MG cells into mouse brain followed by intravenous administration with ALZ003. In addition to inhibiting the growth of glioblastoma, ALZ003 significantly extended the survival period of transplanted mice, and significantly decreased AR expression in the tumor area. Taken together, AR potentiates TMZ resistance for glioblastoma, and ALZ003-mediated AR ubiquitination might open a new insight into therapeutic strategy for TMZ resistant glioblastoma.

Abstract
Cytochrome P450 (CYP) 17A1 is an important steroidogenic enzyme harboring 17α-hydroxylase and performing 17,20 lyase activities in multiple steps of steroid hormone synthesis, including dehydroepiandrosterone (DHEA) biosynthesis. Previously, we showed that CYP17A1-mediated DHEA production clearly protects glioblastomas from temozolomide-induced apoptosis, leading to drug resistance. Herein, we attempt to clarify whether the inhibition of CYP17A1 has a tumor-suppressive effect, and to determine the steroidogenesis-independent functions of CYP17A1 in glioblastomas. Abiraterone, an inhibitor of CYP17A1, significantly inhibits the proliferation of A172, T98G, and PT#3 (the primary glioblastoma cells) by inducing apoptosis. In parallel, abiraterone potently suppresses tumor growth in mouse models through transplantation of PT#3 cells to the back or to the brain. Based on evidence that abiraterone induces endoplasmic reticulum (ER) stress, followed by the accumulation of reactive oxygen species (ROS), CYP17A1 is important for ER health and redox homeostasis. To confirm our hypothesis, we showed that CYP17A1 overexpression prevents the initiation of ER stress and attenuates ROS production by regulating SAR1a/b expression. Abiraterone dissociates SAR1a/b from ER-localized CYP17A1, and induces SAR1a/b ubiquitination, leading to degradation. Furthermore, SAR1 overexpression rescues abiraterone-induced apoptosis and impairs redox homeostasis. In addition to steroid hormone synthesis, CYP17A1 associates with SAR1a/b to regulate protein processing and maintain ER health in glioblastomas.

Abstract
Because radiotherapy (RT) can induce diaphragm dysfunction, this study investigated the protective effect of inspiratory muscle training (IMT) on RT-induced diaphragm damage in patients with esophageal cancer during concurrent chemoradiotherapy (CCRT) in a preclinical setting, and an animal model was designed to confirm and explore the underlying mechanism. Six subjects who underwent CCRT were randomly enrolled in the control or concurrent-IMT group (n=3 per group). The training intensity was set to 30% maximal effort. The diaphragmatic function and functional exercise capacity were assessed weekly during the course of CCRT. Furthermore, Sprague-Dawley (SD) rats were randomly assigned to receive IMT using the tracheal banding method over a 1-week period (n=6) or the sham group (n=6). After training was completed, 5-Gy RT was applied to the diaphragm. All the rats were sacrificed 24 h following RT, and their diaphragms were removed and examined for contractile function, antioxidant capacity, and oxidative injury. In patients receiving IMT, the diaphragm activation efficiency and fatigability and the functional exercise capacity were improved during the CCRT course. The animals belonging to the training group demonstrated significantly higher peak twitch (P<0.01) and tetanus tension (P<0.001), less fatigue (P=0.04), lower protein carbonyl levels (P<0.01) and higher Cu/Zn-SOD and Mn-SOD mRNA expression levels (both P<0.05) compared with those belonging to the control group. Preclinical human and animal models show that the IMT-conditioned diaphragm exhibits better resistance to off-target irradiation damage, but studies with a larger patient sample size are warranted to confirm the applicability of this concept in clinical practice.

Abstract
Objectives: To evaluate the clinical characteristics and prognosis of high risk cytogenetic abnormalities (HRCA) and various combinations of cytogenetic abnormality in patients with newly-diagnosed multiple myeloma (NDMM) . Methods: This retrospective study collected 182 NDMM patients in the First Affiliated Hospital of Jilin University between Nov. 2009 and May 2018. HRCA included 1q+, del (17p) , t (4;14) , and t (14;16) detected by FISH, and non-HRCA included del (13q) , t (11;14) detected by FISH. The clinical characteristics among three groups, including cases who carrying a single HRCA, 1 HRCA in combination with non-HRCA and cases carrying two or more HRCAs (double/triple-hit) were observed. Kaplan-Meier curve was used to analyze both progression-free survival (PFS) and overall survival (OS) for the three groups. Results: The survivals of patients with 1 HRCA in combination with non-HRCA were similar to those with two or more HRCAs (double/triple-hit) , the median PFS (mPFS) was 19.1 m vs 12.1 m (P=0.248) and median OS (mOS) was 29.6 m vs 29.3 m (P=0.774) . Furthermore, the prognosis of these two groups were both inferior to patients with a single HRCA, respectively. (mPFS: 32.2 m, P=0.040, P=0.001; mOS: 42.3 m, P=0.021, P=0.041) . Strikingly, both the mPFS and the mOS of patients with 1 HRCA in combination with non-HRCA (regardless of high risk or not) were significantly shorter than that of cases with a single HRCA (mPFS: 15.1 m vs 32.2 m, HR=2.126, 95%CI 1.176-3.843, P=0.005; mOS: 29.3 m vs 42.3 m, HR=1.442, 95%CI 0.705-2.950, P=0.011) . Conclusion: It is of prognostic significance value for detecting double/triple-hit based on FISH cytogenetics in NDMM.

Abstract
Background: Pulmonary rehabilitation (PR) is now considered fundamental when managing patients with chronic respiratory disease. The individual variation in functional exercise capacity (FEC) response to PR within the cohort is unknown. The purpose of this study was to identify FEC patterns in response to PR in patients with chronic respiratory disease using the trajectory modeling method. Methods: The data of 67 patients with the chronic respiratory disease were retrospectively reviewed and analyzed in this study. All patients received once-weekly supervised training for 8 weeks. Six-minute walk distance (6MWD) was used to measure FEC. Muscle strength and 6MWD were assessed at baseline, Week 4, Week 8 and monthly for two months after PR completion. Group-based trajectory modeling (GBTM) was used to identify patterns in 6MWD in response to PR. The generalized estimating equation method was then used to detect the differences within and between the trajectories of identified groups across time. Results: Patients were grouped into low- (n=13), moderate- (n=34) and high- (n=20) FEC group based on GBTM analysis. All groups demonstrated significant improvements in 6MWD and leg muscle strength after 8-week PR. Compared to the high-FEC group, a greater proportion of the patients in the low-FEC group required oxygen supplementation during training and had worse baseline leg muscle strength. Conclusions: Patients showed distinct patterns of 6MWD changes in response to 8-week PR. Distinct characteristics for the low-FEC group included poor lower extremity strength and a greater proportion of required oxygen use at home and during training. ![]()

Abstract
RATIONALE Bariatric surgery is the recommended treatment for morbid obesity because of its rapid and sustained body weight loss effect. Nutrient deficiency-related neurological complications after bariatric surgery are often disabling. Thus, early recognition of these complications is important. Neurological complications involving the central and peripheral nerve system after bariatric surgery were reported. However, the report on the clinical course of the concurrent involvement of central and peripheral nervous system is limited. We present a rare case of a patient who developed Wernicke encephalopathy concurrent with polyradiculoneuropathy after receiving bariatric surgery. PATIENT CONCERNS A 22-year-old man with a history of morbid obesity presented progressive bilateral lower limbs weakness, blurred vision, and gait disturbance 2 months after receiving laparoscopic sleeve gastrectomy. Bilateral lower limb numbness and cognition impairment were also noted. DIAGNOSIS Brain magnetic resonance imaging and electrophysiologic studies confirmed the diagnosis of Wernicke encephalopathy concurrent with acute polyradiculoneuropathy. INTERVENTIONS Vitamin B and folic acid were given since admission. He also received regular intensive rehabilitation program. OUTCOMES The subject's cognitive impairment and diplopia improved 1 week after admission under medical treatments, yet lower limb weakness and gait disturbance were still noted. After a month of intensive inpatient rehabilitation, he was able to ambulate with a walker for 30 munder supervision. LESSONS Nutrient deficiency-related neurological complications after bariatric surgery are often disabling and even fatal. Prevention of neurological complications can be improved through close postsurgical follow-up of the nutritional status. Recognizing the signs and symptoms and evaluating the medical history are critical to the early diagnosis and treatment of this potentially serious yet treatable condition.

Abstract
Background The prevalence rate of reflux esophagitis (RE) in Asia, including Taiwan, has increased dramatically in recent years. However, few studies have discussed on its relationship with metabolic syndrome (MetS). This study aimed to evaluate the correlation between RE and MetS and its components. Methods We conducted a cross-sectional study during 2013 to 2014 in Taiwan. A total of 4895 subjects who completed upper gastrointestinal endoscopy at the Health Examination Center of Changhua Christian Hospital were enrolled. RE was defined according to the upper gastrointestinal endoscopic findings and MetS was defined according to the Taiwanese criteria. Univariate and multivariate logistic regression analyses were applied to calculate odds ratios and 95% confidence intervals for each variable to assess the associated features for RE. We analyzed the relationship between the number of MetS components and the severity of RE using the chi-square test for trend. Results The prevalence rates of MetS and RE were respectively 28.5 and 59.6%. According to univariate logistic regression analysis, MetS was significantly associated with RE and remained a positive association in multivariate logistic regression analysis (adjusted ORß = 1.251; 95% CI = 1.071–1.462; p = 0.005). Furthermore, among the five MetS components, elevated blood pressure (adjusted ORγ = 1.163; 95% CI = 1.023–1.323; p = 0.021), abdominal obesity (adjusted ORγ = 1.173; 95% CI = 1.020–1.349; p = 0.026) and hyperglycemia (adjusted ORγ = 1.306; 95% CI = 1.142–1.495; p < 0.001) were positively associated with the presence of RE. A weak association was also found between elevated triglycerides and RE after adjusting for age and gender (adjusted ORα = 1.171; 95% CI = 1.022–1.343; p = 0.023). Reduced high-density lipoprotein cholesterol showed no significant difference between groups with and without RE. Older age (≥65 years), male gender, higher body mass index, higher uric acid, smoking, alcohol drinking, and hiatal hernia were found to be significant associated factors for RE. In addition, a dose-response relation between the number of MetS components and the presence of RE was demonstrated in the multivariate analysis. Furthermore, we performed a trend analysis and found the severity of RE got worse as the number of MetS components increased (p < 0.001). Conclusion This study suggests that MetS is significantly related to the presence and the severity of RE.

Abstract
Crystal transformation between two polymorphs (green, 1-G, and red, 1-R) of the square-planar nickel complex NiL2 (L = 2-ethoxy-6-( N-methyliminomethyl)phenolate) and their tuning effect to semiconductor properties were studied both experimentally and theoretically. When 1-G is heated to 413 K, it converts to 1-R, whereas soaking 1-R in several kinds of solvents causes it to revert to 1-G. Crystallographic and PXRD studies reveal the dramatic changes in crystal dimensions due to the changes of packing models. Heating device made from 1-G (D-1-G(298)) at 413 K significantly increases the electrical conductivity from 6.55 × 10-4 S cm-1 for D-1-G(298) to 1.11 × 10-3 S cm-1 for D-1-G(413), showing significant crystal form dependence. Heat-treating D-1-G and D-1-R devices at different temperatures clearly reveals the reason for the conductivity tuning. Thus, the conductivity of NiL2-based devices could be well tuned through crystal transformation by heating or by soaking in solvent. Theoretical calculations clearly revealed the reason for such conductivity changes and also predicted that both polymorphs are good p-type semiconductors with hole mobilities of 1.63 × 10-2 (1-G) and 2.11 × 10-1 cm2 V-1 s-1 (1-R).

Abstract
Butein is a chalcone, a flavonoid that is widely biosynthesized in plants. Butein has been identified to possess varied pharmacological activity and is extractable from traditional Chinese medicinal herbs, therefore applicable for disease treatment. Recently, in vitro and in vivo studies have shown that butein may induce apoptotic cell death in various human cancer cells. In this study we investigated the apoptotic effect of butein and the underlying mechanisms in human cervical cancer cells. Two cell lines, C-33A and SiHa cells, were treated with butein at different dosages for different durations. The effect of butein on cell viability was assessed by MTT assay, which revealed that butein exerted cytotoxicity in both cervical cancer cells in a dose- and time-dependent fashion. Apoptotic pathway-related factors in the butein-treated cervical cancer cells were then examined. JC-1 flow cytometry, cytochrome c assay, and caspase activity assays demonstrated that butein disturbed mitochondrial transmembrane potential, and increased cytosolic cytochrome c levels and caspase activities in both cervical cancer cells. Western blot analysis revealed that butein downregulated anti-apoptotic protein Bcl-xL and led to proteolytic cleavage of poly (ADP-ribose) polymerase. In addition, butein decreased expressions of the inhibitor of apoptosis (IAP) proteins, including X-linked IAP, survivin, and cellular IAP-1. The findings of this study suggest that butein can decrease cervical cancer cell viability via a pro-apoptotic effect, which involves inhibition of the IAP proteins and activation of both extrinsic and intrinsic pro-apoptotic pathways. Therefore, butein may be applicable for cervical cancer treatment.

Abstract
Background Metabolic syndrome is a worldwide disorder and also the major risk factor of several systemic diseases. Evidence identifying the association between metabolic syndrome and nephrolithiasis is lacking, especially in Taiwan. Aim The aim of this study was to investigate the association between nephrolithiasis and metabolic syndrome and its components. Design and setting This was a cross-sectional study conducted in the Health Examination Department of a medical center in Changhua, Taiwan, from January 2010 to December 2010. Methods We reviewed the medical records of patients who had visited the Health Examination Center of Changhua Christian Hospital in 2010. A total of 3,886 individuals were enrolled. According to the exclusion criteria, those with an age <20 years and an abnormal renal function were excluded. A total of 3,793 subjects were included. All P-values are two tailed, and P<0.05 was defined as statistically significant. Results The results showed a correlation between nephrolithiasis and metabolic syndrome and its components. The multivariate-adjusted odds ratio (OR) (95% confidence interval [CI]) of metabolic syndrome for nephrolithiasis was 1.318 (1.083–1.604), with a P-value of 0.006. Larger waist circumference (multivariable-adjusted OR 1.338; 95% CI 1.098–1.631; P=0.004), higher blood pressure (multivariable-adjusted OR 1.333; 95% CI 1.106–1.607; P=0.003), and increased fasting glucose (multivariable-adjusted OR 1.276; 95% CI 1.054–1.546; P=0.01) were associated with nephrolithiasis. Conclusion This is the first study in Taiwan to investigate the relationship between metabolic syndrome and nephrolithiasis. The mechanism is controversial, and several hypotheses are offered. Adequate lifestyle modification and proper treatment in metabolic syndrome management may both contribute to nephrolithiasis prevention.

Abstract
BACKGROUND Norcantharidin, a modified pure compound from blister beetles, was previously demonstrated to induce apoptosis of cancer cells. This study investigated its anti-cancer activity in prostate cancer cells and the mechanisms involved. METHODS Two human prostate cancer cell lines, 22Rv1 and Du145, were treated with norcantharidin at concentrations ranging from 3 to 30μg/ml. Cytotoxic effect of norcantharidin was determined by use of the 3-(4,5-dimethylthiazol-yl)-diphenyl tetrazoliumbromide (MTT) assay. The effects of apoptosis were evaluated by cell death assay, Caspase-3, -8, -9 activity and cytochrome c release. The apoptotic related protein expressions (Bcl-2 family and inhibitor of apoptosis proteins) were determined using western blotting. RESULTS An MTT assay revealed that norcantharidin induced cytotoxicity against both prostate cancer cells in dose- and time-dependent manners. Treatment with norcantharidin at 3μg/ml or higher significantly increased oligonucleosomal formation with concomitant appearance of PARP cleavage, implicating the induction of apoptosis. Norcantharidin intrinsically elevated cytosolic cytochrome c levels and activated caspase-3, -8, and -9. Extrinsically, it upregulated the expression of not only the death receptors Fas and DR5 in 22Rv1 cells, but also of RIP and TRADD adaptor proteins in Du145 cells. Mechanistically, norcantharidin increased ratios of pro-/anti-apoptotic proteins and decreased expression of IAP family member proteins, including cIAP1 and survivin, regardless of the distinct status of androgen receptor expression in both cells. CONCLUSIONS Norcantharidin exhibited cytotoxicity against 22Rv1 and Du145 prostate cancer cells by inducing both intrinsic and extrinsic apoptotic pathways and could thus potentially be a remedy for prostate cancer.

Abstract
The aim of this study was to elucidate the relationship between spinal cord injury (SCI) and the risk of peripheral arterial disease (PAD) in a cohort study with a large representative sample.The National Health Insurance Database was used to select patients who were diagnosed from 2000 to 2010. Patients with a history of PAD were excluded. The SCI group comprised 42,673 patients diagnosed with SCI, and we enrolled 170,389 matched controls (non-SCI group). We used a Cox proportional hazards regression model to analyze the adjusted risk of PAD between the case and control patients.Patients with SCI exhibited a significantly higher risk (hazard ratio [HR] = 1.37; 95% confidence interval [CI] = 1.22-1.53) of PAD than patients without SCI. Patients with diabetes were at the highest risk of developing PAD (adjusted HR = 3.11, 95% CI = 2.80-3.44). Among patients without comorbidity, SCI patients exhibited a significantly higher risk of PAD than non-SCI patients. Furthermore, lumbar, sacral, or coccygeal spine, and multiple spine SCI were significantly associated with an increased risk of PAD (HR = 1.56, 95% CI = 1.33-1.84, HR = 2.11, 95% CI = 1.59-2.79, respectively).SCI is associated with an increased risk of PAD. Future studies should focus on modifying risk factors to reduce PAD risk among patients with SCI.

Abstract
Butein is a polyphenol, one of the compounds of chalcones, which are flavonoids that are widely biosynthesized in plants, and exhibits different pharmacological activities. Plants containing butein have been used in Chinese traditional medicine. Recently, it has been reported that butein suppresses proliferation and triggers apoptosis in various human cancer cells in vitro and in vivo. The aim of this study was to investigate its pro-apoptotic effect and mechanisms in two cultured human ovarian cancer cells (ES-2 and TOV-21G). The effects of butein on cell viability were assessed by a MTT assay at 3, 10, 30, and 100 μ/M. The apoptotic pathway related factors, including the mitochondrial transmembrane potential (MTP), cytochrome c, caspase cascade, and Bcl-2 family proteins, were examined. MTT assay revealed that butein was cytotoxic to both ovarian cancer cells in a dose- and time-dependent manner. JC-1 flow cytometry, cytochrome c, and caspase activity assays revealed that butein damaged the MTP, increased the level of cytosol cytochrome c and the activities of caspase-3, -8, and -9 in the two ovarian cancer cells. Western blot analysis revealed that butein down-regulated the anti-apoptotic proteins Bcl-2 and Bcl-xL and increased the pro-apoptotic proteins Bax and Bad. These findings suggest that butein-induced apoptosis in ovarian cancer cells via the activation of both extrinsic and intrinsic pathways. In addition, butein also down-regulated the expressions of the inhibitor of apoptosis (IAP) proteins, XIAP, survivin, CIAP-1, and CIAP-2. This indicates that the inhibition of IAP proteins was also involved in butein-induced apoptosis. The results of our study suggest that butein may be a promising anticancer agent in treating ovarian cancer.

Abstract
BACKGROUND AND OBJECTIVES Six patients died and one patient survived following infusion of a specific lot of intravenous immunoglobulin (IVIG) within half an hour in May 2008. This study elucidated the underlying pathogenesis. MATERIALS AND METHODS A variety of protein fractionation and identification approaches were employed to determine the abnormal components in IVIG products obtained from the hospital where the patients were treated. Animal studies using mice and monkeys were conducted to elucidate the pathophysiological mechanisms. In animal experiments, the effect and distribution of immunoglobulin was investigated using HE staining and immunohistochemistry (IHC) separately, while platelets and fibrinogen depletion were utilized to determine a possible link between thromboembolism formation in animals and the lethal effect of the IVIG. The size and distribution of the protein aggregates were determined with Coulter Counter Multisizer-3 after the dilution of the IVIG with plasma, and the lethal effect of the protein aggregates was simulated with artificial microparticles. RESULTS The IVIG retrieved from the hospital was found to have striking similarities to the heat-treated IVIG in terms of protein aggregation profiles and lethal effects. Post-mortem examination indicated that immunoglobulin aggregates were mainly found in the lung of the animals, while depletion of platelets and fibrinogen from the IVIG preparations failed to prevent the death of the animals. Similar amount of artificial microparticles caused animal death in similar fashion. CONCLUSIONS Our findings indicate that the retrieved IVIG exerted its lethal effects by blocking the pulmonary circulation without markedly altering the coagulation cascade or immunological events.

Abstract
The correlation between hip replacement (Hip-Rep) and peripheral arterial disease (PAD) remains uncertain. Thus, we investigated the relationship between Hip-Rep and risk of developing PAD in a nationwide retrospective cohort study.National Health Insurance data were used to assemble a cohort of patients who were diagnosed from 2000 to 2011. Patients with a history of PAD were excluded. A total of 5284 patients who received a Hip-Rep and 21,124 matched controls were enrolled. We used Cox proportional hazards regression model to analyze the adjusted risk of developing PAD.The risk of developing PAD in the Hip-Rep group was 1.24-fold higher (95% CI = 1.05-1.48) than that in the control group. The adjusted risk of developing PAD increased with patient age; compared with patients aged 50 years or younger, the risk among those ages at least 80 years was 4.87-fold higher. Patients with diabetes exhibited the highest risk of developing PAD (HR = 1.58, 95% CI = 1.34-1.86). Compared with patients who had not received a Hip-Rep or reported any comorbidity, patients who received a Hip-Rep were 2.45-fold more likely to develop PAD (95% CI = 1.54-3.89); the risk increased with the number of comorbidities.Hip-Reps might be independently linked with an increased risk of developing PAD. The impact of Hip-Reps on this risk was greater in women and patients ages 65 years and younger and within the first year of follow-up.

Abstract
The effect of sludge retention time (SRT) on biomass, kinetic parameters, and stoichiometric parameters of ammonia-oxidizing bacteria (AOB) and nitrite-oxidizing bacteria (NOB) in anaerobic/anoxic/oxic (A(2)O) process were explored in this study. The results showed that the growth rate constants were 1.52, 1.22, and 0.85 day(-1), respectively, for AOB, those were 1.59, 1.19, and 0.87 day(-1), respectively, for NOB when SRT was 20, 10, and 5 days. The lysis rate constants of AOB and NOB were 0.14 and 0.09 day(-1), respectively. The yield coefficients were 0.23 and 0.22, respectively, for AOB and NOB. They did not change with SRT obviously. The biomass of AOB was 50.94, 26.35, and 14.68 mg L(-1), respectively, and the biomass of NOB was 116.77, 60.00, and 44.25 mg L(-1), respectively, at SRT of 20, 10, and 5 days. When SRT diminished from 20 to 5 days, the biomass of AOB and NOB diminished by 36.26 and 75.52 mg L(-1), respectively. The removal efficiency of NH4 (+)-N diminished by 68.9 %. The removal efficiency of total nitrogen diminished by 42.9 %.

Abstract
Antrodia camphorata is a Chinese herb indigenous to Taiwan. Previous reports demonstrated that it could induce apoptosis in some cancer cells. The purpose of this study was to investigate the apoptotic effect of the crude extract of A. camphorata in cervical cancer cells. Two human cervical cancer cell lines, HeLa and C-33A, were treated with extract of A. camphorata (10-1000 μg/mL). We found that A. camphorata extract was cytotoxic to both cervical cancer cells in a dose- and time-dependent manner as examined by MTT assay. Treatment with A. camphorata extract at 400 μg/mL induced a 2.3- and 4.4-fold increase in oligonucleosome formation from the cleaved chromosomal DNA in HeLa and C-33A cells, respectively. A. camphorata extract also activated caspase-3, -8, and -9 activities and increased the cytosolic level of cytochrome c in both cell lines as the dosage increased. Furthermore, A. camphorata extract increased expressions of Bak, Bad and Bim, while decreasing expressions of Bcl-2 and Bcl-xL of the Bcl-2 family proteins in HeLa and C-33A cells. The expression of IAP proteins, XIAP and survivin, was also decreased in both cervical cancer cells after treatment with A. camphorata. Our in vitro study suggests that A. camphorata is cytotoxic to cervical cancer cells through both extrinsic and intrinsic apoptotic mechanisms. It could be used as a novel phytotherapeutic agent or auxiliary therapy in the treatment of cervical cancer.

Abstract
QUESTION Does an exercise training program improve the quality of sleep in middle-aged and older adults with sleep problems? DESIGN Systematic review with meta-analysis of randomised trials. PARTICIPANTS Adults aged over 40 years with sleep problems. INTERVENTION A formal exercise training program consisting of either aerobic or resistance exercise. OUTCOME MEASURES Self-reported sleep quality or polysomnography. RESULTS Six trials were eligible for inclusion and provided data on 305 participants (241 female). Each of the studies examined an exercise training program that consisted of either moderate intensity aerobic exercise or high intensity resistance exercise. The duration of most of the training programs was between 10 and 16 weeks. All of the studies used the self-reported Pittsburgh Sleep Quality Index to assess sleep quality. Compared to the control group, the participants who were randomised to an exercise program had a better global Pittsburgh Sleep Quality Index score, with a standardised mean difference (SMD) of 0.47 (95% CI 0.08 to 0.86). The exercise group also had significantly reduced sleep latency (SMD 0.58, 95% CI 0.08 to 1.08), and medication use (SMD 0.44, 95% CI 0.14 to 0.74). However, the groups did not differ significantly in sleep duration, sleep efficiency, sleep disturbance, or daytime functioning. CONCLUSION Participation in an exercise training program has moderately positive effects on sleep quality in middle-aged and older adults. Physical exercise could be an alternative or complementary approach to existing therapies for sleep problems.

Abstract
Uveal melanoma, the most common primary intraocular malignancy in adults, is highly resistant to most chemotherapeutic drugs. Arsenic trioxide (ATO) is known to inhibit ocular melanoma cell growth. However, the effects of ATO on human uveal melanoma cells are poorly understood. Therefore, this study evaluated the mechanisms of ATO and its inhibiting effects on a human uveal melanoma cell line (SP6.5). An MTT assay indicated that, compared to human fibroblasts, ATO had a stronger inhibiting effect on SP6.5 cell proliferation in a dose- and time-dependent manner. The apoptosis ratio in SP6.5 cells, which was indicated by cell DNA fragmentation, was 4.1- to 7.7-fold higher after ATO-treatment. The ATO treatment substantially increased the activities of caspase-3 and caspase-9, but not of caspase-8. These findings were consistent with the protein expression observed by Western blots. ATO also significantly enhanced expression of Bax and cytochrome c proteins but suppressed those of Bcl-2. Therefore, ATO-induced apoptosis in uveal melanoma cells occurs mainly through the mitochondrial pathway rather than through the death receptor pathway. This report is the first to evaluate the complete mitochondria-dependent apoptotic pathway of ATO in uveal melanoma cells. These results can be used to improve the clinical effectiveness of ATO treatment for uveal melanoma.

Abstract
Well-aligned Ga-doped ZnO nanorod arrays with high optical and electrical property were fabricated by catalyst-free thermal evaporation on p-silicon substrate. As the Ga/Zn atom ratio in the source material was tuned from 0 to 0.2, wurtzite structure ZnO nanorod arrays were realized with length of -6 microm and growth direction along c-axis. With the addition of Ga, the intensity of the near-band-edge emission was enhanced and the deep-level emissions maintained neglectable. As the Ga/Zn atom ratio increased from 0 to 0.1, the red shift of the near-band-edge emission occurred due to Ga-doping induced band gap renormalization effect related with the enhancement of the carrier density, while the blue shifts of the emission were found once the Ga/Zn ratio is higher than 0.1 resulting from Burstein-Moss effect. The configuration of the vertical-aligned Ga-doped ZnO nanorod arrays on p-Si substrate makes it straightforward for the fabrication of p-n nanodiode, which shows an excellent rectifying characteristic with threshold voltage as low as -4.7 V with the Ga/Zn atomic ratio of 0.2.

Abstract
PURPOSE Urinating while standing is a possible alternative for elderly women with knee osteoarthritis when a sitting toilet is unavailable. We evaluated uroflowmetric characteristics and post-void residual urine volume in elderly women with knee osteoarthritis who urinated while standing. MATERIALS AND METHODS We recruited 21 women with a mean±SD age of 65.0±4.6 years who had a knee osteoarthritis Lequesne index score of at least 6 points and were unable to maintain or found it difficult to stand up from a squat or crouch. Participants used a homemade auxiliary appliance to collect urine and drain it forward while stand voiding. Uroflowmetric data, including voided volume, and maximal and average flow rates, were recorded. Post-void residual urine volume was detected using an ultrasound bladder scanner. Participants completed a questionnaire to evaluate their attitude toward stand voiding and using the auxiliary device. RESULTS Maximal and average flow rates, and voided and post-void residual urine volumes were not statistically different while sitting and standing. No learning curve was noted for stand voiding. Uroflowmetry patterns while standing were smooth. Of the 21 participants 17 (81%) experienced no difficulty while stand voiding. All expressed willingness to urinate while standing position if they did not have access to a satisfactorily clean toilet seat. CONCLUSIONS Urinating while standing is a feasible option for elderly women with knee osteoarthritis who have difficulty crouching or squatting to void in public restrooms.

Abstract
AIMS This study aims to evaluate the voiding disorder and lower urinary tract symptoms in mentally retarded children. METHODS Fifty-one mentally retarded children (age 7.7 years) was assessed. A volunteer sample comprised of 36 typically developing children (age 6.4 years) served as the comparative group. All participants underwent uroflometric investigation, and residual urine was detected by sonography. Urological history including history of urinary tract infection, incontinence, frequency, and dysurea was collected. In addition, the mentally retarded group was classified according to IQ: severe mentally retarded group (IQ below 40) (n = 11), moderate mentally retarded group (IQ: 41 to 55) (n = 19), mild mentally retarded group (IQ: 56 to 70) (n = 21). Group comparisons were analyzed using Chi-square and Student's t-test. RESULTS Of the 51 mentally retarded children, 18(35.2%) were found to have voiding dysfunction, which is significantly higher than the control group (8.3%). The incidence of urine incontinence and frequency is also significantly higher in the mentally retarded group. The comparison of the three mentally retarded subgroups showed that the severe mentally retarded group had the highest incidence of voiding dysfunction and urinary incontinence. Overall, the mentally retarded group had higher percentage of small bladder capacity. CONCLUSIONS We concluded that mentally retarded children have a higher incidence of voiding dysfunction and incontinence than the control group. Early detection of voiding dysfunction in an objective, non-invasive manner is important in mentally retarded children, particularly those with severe cognitive impairment.

Abstract
PURPOSE Urokinase-type plasminogen activator (uPA) is a protease involved in tissue remodeling and cell migration. Little is known about the expression of uPA in pterygium. The purpose of this study was to investigate the expression of uPA mRNA and activities in various stages of surgically excised pterygia specimens and cultured pterygium fibroblasts and to compare them with normal conjunctival tissues and fibroblasts. METHODS The expression of uPA mRNA and activity in 15 pterygium tissues and cultured fibroblasts from pterygium were measured using quantitative RT-PCR and zymography. Five normal conjunctiva specimens and cultured conjunctival fibroblasts were tested as the controls. RESULTS The expression of uPA mRNA and activities in pterygia and pterygium fibroblasts were significantly greater than those of the normal samples (p<0.05) and were closely related to the progression of pterygium. The amounts of uPA mRNA and activities in early, moderate, and advanced pterygia were 100%, 208%, and 311% and 100%, 157%, and 280% of the early stage specimens, respectively. The amounts of uPA mRNA and the activities in cultured pterygium fibroblasts isolated from early, moderate, and advanced pterygium specimens were 100%, 219%, and 457% and 100%, 198% and 355% of early stage fibroblasts, respectively. CONCLUSIONS Overexpression of uPA was present in pterygium and their fibroblasts. The expression of uPA by pterygium increased significantly following the progression of the pterygium. The increased expression of uPA may covert plasminogen to plasmin, degrade extracellular matrixes, stimulate cell migration, induce angiogenesis, and plays an important role in the development and progression of pterygium.

Abstract
Papaya processing waste (PPW), a major fruit processing waste in the Hawaii islands, served as substrate for yeast (Saccharomyces cerevisiae) growth. The fermented PPW products containing nutrients of 45% crude protein and various fat, fiber, lignin, cellulose, and minerals were advantages to nutrients of yeast alone. Three experimental diets controlled at 35% protein formulation containing different levels of inclusion of PPW products and a commercial control diet were fed to shrimps for 8 weeks. The 50% inclusion of PPW diets were comparable to commercial feed in weight, growth, feed conversion ratio (FCR) and survival rate. Such bioprocess treatment system would be economically feasible with the control of annual cost and increase of the amount of PPW treated. The selling price of PPW products and annual operation and maintenance cost were the most influential factors to additional profits. This study presented a promising alternative for environmental-friendly treatment of organic wastes as well as the sustainability of local agriculture and aquaculture industries.
