Abstract
A series of novel benzimidazole derivatives were designed and synthesised based on the structures of reported oral available ALK inhibitor and HDAC inhibitor, pracinostat. In enzymatic assays, compound 3b, containing a 2-acyliminobenzimidazole moiety and hydroxamic acid side chain, could inhibit both ALK and HDAC6 (IC50 = 16 nM and 1.03 µM, respectively). Compound 3b also inhibited various ALK mutants known to be involved in crizotinib resistance, including mutant L1196M (IC50, 4.9 nM). Moreover, 3b inhibited the proliferation of several cancer cell lines, including ALK-addicted H2228 cells. To evaluate its potential for treating cancers in vivo, 3b was used in a human A549 xenograft model with BALB/c nude mice. At 20 mg/kg, 3b inhibited tumour growth by 85% yet had a negligible effect on mean body weight. These results suggest a attracting route for the further research and optimisation of dual ALK/HDAC inhibitors.

Abstract
BACKGROUND/AIM The capacity for non-homologous end-joining (NHEJ) repair plays a pivotal role in maintaining genome stability and in carcinogenesis. However, there is little literature on the involvement of NHEJ-related genes in childhood acute lymphocytic leukemia (ALL). Our study aimed to elucidate the impact of polymorphisms of X-ray repair cross-complementing group 4 (XRCC4) (rs6869366, rs2075685, rs2075686, rs28360071, rs3734091, rs28360317, rs1805377), XRCC5 (rs828907, rs11685387, rs9288518), XRCC6 (rs5751129, rs2267437, rs132770, rs132774), XRCC7 rs7003908, and DNA ligase IV (LIG4) rs1805388, on the odds of childhood ALL. MATERIALS AND METHODS Genotypes NHEJ-related genes of 266 cases and 266 controls were determined, and the genotype-phenotype correlation was investigated by examining mRNA transcript expression and the capacity for overall and precise NHEJ repair. RESULTS The variant genotypes of XRCC4 rs3734091, rs28360071, XRCC5 rs828907, and XRCC6 rs5751129 were significantly associated with increased odds of childhood ALL. Further analysis based on susceptibility genotypes showed no significant differences in mRNA transcript expression levels among childhood ALL cases with various putative high-risk genotypes, except XRCC6 rs5751129. Moreover, the overall NHEJ repair capacity was similar among carriers of different XRCC4, XRCC5, and XRCC6 genotypes. However, it is worth noting that individuals carrying the variant C allele at XRCC6 rs5751129 exhibited lower precise NHEJ repair capacity compared to those with the wild-type T allele. CONCLUSION Our study identified significant associations between XRCC4 rs3734091, rs28360071, XRCC5 rs828907, and XRCC6 rs5751129 genotypes and childhood ALL. Notably, lower transcriptional expression and reduced precise NHEJ repair capacity were observed in patients carrying the C allele of XRCC6 rs5751129. Further investigations are required to gain deeper insights into childhood ALL development.

Abstract
BACKGROUND Sexual health is a taboo issue in some societies. Limited assessments were conducted during nursing care in mental health services. It is unknown whether psychiatric nurses' competencies would be enhanced through short training courses. AIMS The present study employed a quasi-experimental design to evaluate the effectiveness of an 8-hour sexual health care training for psychiatric nurses to improve sexual health knowledge, attitude, and self-efficacy in a teaching psychiatric hospital in southern Taiwan. METHOD Volunteered psychiatric nurses were randomly assigned to the experimental or control group. The 8-hour training program contained sexual health knowledge and attitudes, case discussion, role play, and sexual identity or harassment issues. Each nurse received a pretest and a posttest in the 1-month period between August and September 2019. Descriptive and multivariate statistical analyses were used to evaluate the effects. RESULTS Among the 75 psychiatric nurses, 43 were in the control group and 32 were in the experimental group. The two groups were not significantly different in the working year, gender, education, marriage, and other psychosocial variables. After the training, the overall performance of sexual health care knowledge, attitudes, and self-efficacy of the experimental group improved significantly than the controls. CONCLUSIONS The sexual health care training program enhanced psychiatric nurses' confidence and generally improved their sexual knowledge and attitudes. It is suggested that sexual health care needs to be highlighted during in-job training to augment the well-being and life quality of psychiatric patients.

Abstract
BACKGROUND/AIM Interleukin 8 (IL-8) is highly expressed in refractory acute lymphocytic leukemia (ALL) cells. This study aimed to investigate the contribution of IL-8 polymorphisms to the risk of childhood ALL. MATERIALS AND METHODS The genotypes of IL-8 rs4073, rs2227306, rs2227543, and rs1126647 were determined in 266 childhood ALL cases and 266 controls using the PCR-RFLP method. Additionally, we assessed whether the interactions of these genotypes with age and sex contributed to childhood ALL risk. RESULTS The distributions of genotypic and allelic frequencies of IL-8 rs4073, rs2227306, rs2227543, and rs1126647 were not significantly different between childhood ALL cases and controls (all p>0.05). However, carriers of the variant AA genotype at IL-8 rs4073 had a significantly higher risk of childhood ALL among those aged ≤3.5 years and among girls (OR=2.39 and 3.32, 95%CI=1.21-4.73 and 1.51-7.30, p=0.0182 and 0.0042, respectively). In the stratification analysis, IL-8 rs4073 AT and AA genotypes were associated with higher childhood ALL risk classification and shorter survival time (OR=2.21 and 4.13, 95%CI=1.29-3.78 and 1.87-9.10, p=0.0054 and 0.0002, respectively). There was no positive association for rs2227306, rs2227543, or rs1126647 (all p>0.05). CONCLUSION The A allele of IL-8 rs4073 can serve as a diagnostic predictor for childhood ALL, but only in girls and patients younger than or equal to 3.5 years old. More importantly, it can serve as a prognostic marker for high-risk classification and shorter survival time. Further validation studies can help extend the use of this prognostic predictor in clinical practice.

Abstract
BACKGROUND Providing appropriate care to patients with dementia in acute care settings can be a challenge for healthcare professionals. A key factor is working closely with family caregivers. PURPOSE This study aims to explore the difficulties and strategies involved in caring for patients with dementia who have been admitted to an acute care ward from the perspective of family caregivers. METHODS Exploratory research was conducted using a qualitative data collection approach. Data were collected by means of in-depth interviews carried out with participants. Semistructured interviews were conducted with nine participants. Content analysis was performed to analyze the data. RESULTS A number of themes and subthemes were identified based on the primary research purposes. The first theme is "vicious cycle due to multiple factors," with the following subthemes: (a) communication disturbance, (b) endless worries, (c) inadequate care skills of paid caregivers, and (d) physical and psychological exhaustion. The second theme is "do everything," with the following subthemes: (a) management of the behavioral and psychological symptoms of dementia, (b) constant accompaniment of the patient, and (c) seeking sources of support. CONCLUSIONS/IMPLICATIONS FOR PRACTICE The results may be used to help healthcare professionals better anticipate the difficulties faced by family caregivers while providing assistance to patients with dementia and understand the related strategies they use. Acute care wards should consider the specific needs of family caregivers to ensure patients with dementia receive adequate care from the relevant parties in the ecological care chain during the care process.

Abstract
Background:
Spontaneous coronary artery dissection (SCAD) is a cause of acute coronary syndrome that predominantly affects women. Its pathophysiology remains unclear but connective tissue disorders (CTD) and other vasculopathies have been observed in many SCAD patients. A genetic component for SCAD is increasingly appreciated, although few genes have been robustly implicated. We sought to clarify the genetic cause of SCAD using targeted and genome-wide methods in a cohort of sporadic cases to identify both common and rare disease-associated variants.
Methods:
A cohort of 91 unrelated sporadic SCAD cases was investigated for rare, deleterious variants in genes associated with either SCAD or CTD, while new candidate genes were sought using rare variant collapsing analysis and identification of novel loss-of-function variants in genes intolerant to such variation. Finally, 2 SCAD polygenic risk scores were applied to assess the contribution of common variants.
Results:
We identified 10 cases with at least one rare, likely disease-causing variant in CTD-associated genes, although only one had a CTD phenotype. No genes were significantly associated with SCAD from genome-wide collapsing analysis, however, enrichment for TGF (transforming growth factor)-β signaling pathway genes was found with analysis of 24 genes harboring novel loss-of-function variants. Both polygenic risk scores demonstrated that sporadic SCAD cases have a significantly elevated genetic SCAD risk compared with controls.
Conclusions:
SCAD shares some genetic overlap with CTD, even in the absence of any major CTD phenotype. Consistent with a complex genetic architecture, SCAD patients also have a higher burden of common variants than controls.

Abstract
BACKGROUND/AIM Acute lymphoblastic leukemia (ALL) is frequent among children. Few studies have researched the relationship between maternally expressed gene 3 (MEG3) and cancer risk. We hypothesized long non-coding RNA MEG3 polymorphisms might influence the risk of childhood ALL. MATERIALS AND METHODS In a total of 266 patients with childhood ALL and 266 healthy controls, genotypes of MEG3 rs7158663, rs3087918, rs11160608 and rs4081134 single nucleotide polymorphisms were investigated for their associations with childhood ALL. RESULTS MEG3 rs7158663 AG and AA genotypes were significantly associated with ALL [odds ratio=1.61 (95% confidence interval=1.12-2.31) and 2.21 (1.16-4.22), respectively]. The A allele also exhibited a statistical association with higher risk of ALL (p=0.0015). There was no positive association as for rs3087918, rs11160608 or rs4081134. Interestingly, a significant interaction between MEG3 rs7158663 and age (≥3.5 years) and gender (male) was found. CONCLUSION MEG3 rs7158663 AG/AA genotypes were associated with higher susceptibility to childhood ALL. These novel findings should be validated in larger populations and different ethnicities.

Abstract
BACKGROUND/AIM This study investigated whether genetic variations in cyclin D1 (CCND1) are associated with susceptibility to childhood acute lymphoblastic leukemia (ALL). MATERIALS AND METHODS A total of 266 childhood ALL cases and 266 healthy controls were genotyped for CCND1 rs9344 and rs678653. RESULTS There was a significant difference in the genotypic distribution of rs9344 between childhood ALL patients and healthy controls (p=0.0077). Compared to the AA genotype, AG and GG genotypes were associated with significantly decreased risks of childhood ALL with odds ratio (OR) of 0.65 [95% confidence interval (CI)=0.44-0.94, p=0.0234] and 0.45 (95%CI=0.26-0.78, p=0.0040), respectively. Supporting this, allelic frequency distributions between childhood ALL patients and controls was significantly different (OR=0.68, 95%CI=0.53-0.88, p=0.0025). There was no significant difference in the genotypic and allelic distributions of rs678653 between cases and controls. CONCLUSION CCND1 rs9344, but not rs678653, may serve as a predictive marker of susceptibility for childhood ALL.

Abstract
In Taiwan, The increase in life expectancy in Taiwan has increased the incidents of age-related problems among patients with mental illness. Therefore, the needs related to long-term care in mental health are significantly important. These needs include: (1) reducing stigmatization; (2) reducing the physical and economic burden of caregivers; (3) constructing a comprehensive, long-term care service system; and (4) developing assessment tools suitable to the long-term care of patients with mental illness. Moreover, six dilemmas in meeting long-term care needs were identified. These dilemmas include: (1) lack of a model of continuous care and of a platform for integrating hospital and community resources; (2) poor / inadequate service quality provided by certain community rehabilitation institutions; (3) the needs of patient/family centered care; (4) the persistence of stigma and misunderstanding; (5) the heavy burdens borne by family members providing long-term care; and (6) the disconnect between subsequent needs and the disability assessment system. Policy suggestions provided in this article include: (1) establish an inclusive platform for mental health long-term care information and resource integration; (2) construct long-term care centers for patients with mental health conditions; (3) train adequate manpower to provide long-term care services to these patients; and (4) promote community inclusiveness for these patients. In order to enter the era of long-term mental health care, government policy should target long-term care programs to meet the needs of patients with mental health conditions. These programs should include seamlessly integrating services into the long-term mental health care system and the care resources of community mental health, developing suitable assessment tools, establishing a multidisciplinary team of long-term care professionals to provide mental health care.

Abstract
The purpose of our study was to investigate whether genetic variations in lncRNA H19 were associated with susceptibility to childhood leukemia. Two hundred and sixty-six childhood leukemia patients and 266 healthy controls were enrolled in Taiwan, and two single nucleotide polymorphisms (SNPs), rs2839698 and rs217727, in H19 were genotyped and analyzed. There was a significant difference in the genotypic distribution of rs2839698 between patients and healthy controls (p = 0.0277). Compared to the wild-type CC genotype, the heterozygous variant CT and homozygous variant TT genotypes were associated with significantly increased risks of childhood leukemia with an adjusted odd ratio (OR) of 1.46 (95% confidence interval (CI), 1.08–2.14, p = 0.0429) and 1.94 (95%CI, 1.15–3.31, p = 0.0169), respectively (pfor tread = 0.0277). The difference in allelic frequencies between childhood leukemia patients and controls was also significant (T versus C, adjusted OR = 1.53, 95%CI, 1.13–1.79, p = 0.0077). There were no significant differences in the genotypic and allelic distributions of rs217727 between cases and controls. Interestingly, the average level of H19 rs2839698 was statistically significantly higher for patients with CT and TT genotypes than from those with the CC genotype (p < 0.0001). Our results indicate that H19 SNP rs2839698, but not rs217727, may serve as a novel susceptibility marker for childhood leukemia.

Abstract
BACKGROUND/AIM Mounting evidence has shown that miRNAs play a critical role in the regulation of hematopoiesis of cell proliferation and apoptosis as well as in tumorigenesis. The miR146a rs2910164 polymorphism, which is closely responsive for its expression, has been reported to associate with the risk of several solid cancers. The study aimed at examining the association of the it with susceptibility to childhood acute lymphoblastic leukemia (ALL) in Taiwan. MATERIALS AND METHODS We recruited 266 patients with childhood ALL and 266 healthy controls, and rs2910164 genotypes were determined by the polymerase chain reaction-restriction fragment length polymorphism methodology. RESULTS The allele G was associated with decreased childhood ALL risk (OR=0.66, 95%CI=0.52-0.85, p=0.0011). Consistently, the GG genotype was associated with a decreased susceptibility (OR=0.40, 95%CI=0.23-0.67, p=0.0004). Patients with CG and GG genotypes were of earlier onset than those with CC genotype (p=0.0255 and p=0.0001). CONCLUSION MiR146a rs2910164 G allele serves as a protective marker for childhood ALL in Taiwan.

Abstract
Oxidative stress may play critically important roles in the etiology of Parkinson's disease (PD). 6-Hydroxydopamine (6-OHDA) is a physiological neurotoxin reported to induce oxidative-induced apoptosis of dopaminergic neurons in PD mice models. Valproic acid (VPA), a clinical mood stabilizer, is a HDAC inhibitor with neuroprotective capacities. In the study, we aim at examining the feasibility of VPA as a protector for dopaminergic neurons against damage from 6-OHDA, and the intracellular mechanisms. The 6-OHDA-induced neurotoxicity to the human dopaminergic cell line SH-SY5Y was applied for examining VPA protective effects. Pretreatment with VPA was able to improve cell viability and reduce 6-OHDA-induced reactive oxygen species. Furthermore, a significant suppression of apoptotic caspases including cleaved caspase-3, caspase-7, and caspase-9 was observed. The results also revealed VPA decreased the 6-OHDA-induced Bax/Bcl2 ratio, as measured at protein level. These novel findings indicate that VPA may be capable of protecting the SH-SY5Y dopaminergic neuronal cells from 6-OHDA-induced toxicity via the deceasing of apoptotic caspases (cleaved caspase-3, caspase-7, and caspase-9) and reducing of the Bax/Bcl2 ratio. Very possibly, VPA could serve as not only a mood stabilizer but also a potential antidote for PD prevention.

Abstract
BACKGROUND/AIM The roles of microRNAs (miRNAs) in tumorigenesis have attracted a lot of attention. The current study aimed at examining the association of the miR-196a-2 rs11614913 genotypes with susceptibility to childhood acute lymphoblastic leukemia (ALL) in Taiwan. MATERIALS AND METHODS This case-control investigation recruited 266 patients with childhood ALL and 266 healthy controls, and the miR-196a-2 rs11614913 genotypes of each participant were examined via the polymerase chain reaction-restriction fragment length polymorphism methodology. RESULTS The frequency of miR-196a-2 C allele in controls was 0.440 compared with 0.423 in ALL patients. In addition, there was no significant association between CT or CC genotypes with susceptibility to childhood ALL (OR=0.89 and 0.89, 95%CI=0.60-1.30 and 0.54-1.45, p=0.5427 and 0.6302). Furthermore, the frequencies of miR-196a-2 polymorphisms were not associated with age, gender and clinical outcomes in ALL cases. CONCLUSION The miR-19a-2 genotypes are not associated with susceptibility to childhood ALL in Taiwan.

Abstract
BACKGROUND Green lacewings (Neuroptera: Chrysopidae) are important beneficial insects that can be raised on artificial diets for culturing experimental lines. An encapsulation method for embedding a core material within a sealed shell to prevent evaporation and biological contamination is crucial for providing food to these predatory insects. RESULTS This study presents a new encapsulation process to mass produce a core-shell microcapsule diet for rearing Mallada basalis (Walker) (Neuroptera: Chrysopidae). This new process provided consistent quality control and effectiveness of the microcapsule diet (742.1 ± 11.3 μm in diameter and 44.2 ± 1.9 μm in shell thickness). Furthermore, significant differences were measured in larval development (24.0 ± 0.3 vs. 20.1 ± 0.6 days) and fecundity (465 ± 65.05 vs. 678 ± 54.91 eggs) on comparing the development of M. basalis larvae fed the old and new diets. Survival rates increased in both single- and group-rearing tests for adults fed the new diet during the larval stages. Neither diet affected predation rates for M. basalis larvae preying on nymphs of Aphis gossypii Glover (Hemiptera: Aphididae) and Bemisia argentifolli Bellows and Perring (Hemiptera: Aleyrodidae). CONCLUSION Compared with the old process, the new encapsulation process requires reduced effort during preparation, and reduces the weight, cost and space occupied by the equipment. The results of this study suggest that this new spherical microcapsule artificial diet is suitable for group-rearing of M. basalis and may be appropriate for mass-rearing of other types of carnivorous insects. © 2019 Society of Chemical Industry.

Abstract
Background The application of next-generation sequencing in cancer has revealed the genomic landscape of many tumour types and is nowadays routinely used in research and clinical settings. Multiple algorithms have been developed to detect somatic variation from sequencing data using either paired tumour-blood or tumour-only samples. Most of these methods have been developed and evaluated for the identification of somatic variation using Illumina sequencing datasets of moderate coverage. However, a comprehensive evaluation of somatic variant detection algorithms on Ion Torrent targeted deep sequencing data has not been performed. Methods We have applied three somatic detection algorithms, Torrent Variant Caller, MuTect2 and VarScan2, on a large cohort of ovarian cancer patients comprising of 208 paired tumour-blood samples and 253 tumour-only samples sequenced deeply on Ion Torrent Proton platform across 330 amplicons. Subsequently, the concordance and performance of the three somatic variant callers were assessed. Results We have observed low concordance across the algorithms with only 0.5% of SNV and 0.02% of INDEL calls in common across all three methods. The intersection of all methods showed better performance when assessed using correlation with known mutational signatures, overlap with COSMIC variation and by examining the variant characteristics. The Torrent Variant Caller also performed well with the advantage of not eliminating a high number of variants that could lead to high type II error. Conclusions Our results suggest that caution should be taken when applying state-of-the-art somatic variant algorithms to Ion Torrent targeted deep sequencing data. Better quality control procedures and strategies that combine results from multiple methods should ensure that higher accuracy is achieved. This is essential to ensure that results from bioinformatics pipelines using Ion Torrent deep sequencing can be robustly applied in cancer research and in the clinic.

Abstract
BACKGROUND/AIM Cells suffer from oxidative DNA damage which leads to the accumulation of 8-oxoguanine (8-oxoG) adducts in our genome that can become carcinogenic. The human 8-oxoG DNA glycosylase 1 (hOGG1) plays a central role in repairing these 8-oxoGs via the base excision repair pathway. Mounting evidence has suggested that hOGG1 polymorphisms may affect the activity of hOGG1 and serve as genomic markers for the prediction of personal susceptibility to several cancers. To determine whether the commonly examined hOGG1 rs1052133 (Ser326Cys) polymorphism is associated with the risk of childhood acute lymphoblastic leukemia (ALL) among Taiwanese children, we genotyped the hOGG1 rs1052133 (Ser326Cys) in 266 cases and 266 controls. RESULTS The distributions of the GG, CG and CC genotypes at the hOGG1 rs1052133 were 49.2, 39.1 and 11.7% in the control group and 48.1, 36.1 and 15.8% in the case group (p=0.3656). The combined genotypes CG+CC were not associated with increased risk of childhood ALL (odds ratio [OR]=1.05, 95% confidence interval [CI]=0.74-1.47, p=0.7947). CONCLUSION The hOGG1 rs1052133 polymorphism is not associated with susceptibility to childhood ALL in the Taiwanese population.

Abstract
e14638 Background: Breast cancer is the highest incidence malignancies in women worldwide. Luminal breast cancers are typically estrogen receptor–positive with better prognosis. However, the rapid disease progression and the high relapse rate of this subtype of breast cancer have become a puzzle in breast cancer treatment. It gave us the motivation to figure out the anomalous molecular mechanism which devoted in. It has been well-documented that the RAS pathway is overloadly activated in more than half of human breast tumors. RAS genes encode a superfamily of small GTPases that contribute to cell growth signals. Methods: Gene expression level were measured by qPCR and Western Blot.Biological effects of each condition were evaluated in cell viability and migration. Results: In this study, we investigated one member of the RAS family, RERG, which was related to the ER pathway and contributed to inhibit Ras activated pathway. Our results showed that knockdown of RERG concomitantly promoted two major oncogenic pathways, Ras and Stat3 signaling pathways, in luminal type breast cancer cell lines. Moreover, ectopic RERG expression significantly inhibited Ras expression. It implicated that RERG mediated in RAS-driven biological effects. Our findings indicated that knockdown of RERG enhanced mobility of the breast cancer cells and made cells more intractable under SERM treatment. Conclusions: We elucidated the tumor-suppressor role of RERG in breast cancer cells though inhibition of the Ras and Stat3 signaling pathways. Therefore, this study might shed light on the important mechanistic insight into the tumorigenesis of ER-positive luminal type cancer and provided the prognostic and therapeutic improved roles of RERG.

Abstract
BACKGROUND/AIM The association of matrix metalloproteinase-2 (MMP-2) genotypes with adult leukemia has been reported only once, but never for childhood leukemia. This study aimed to determine the role of MMP-2 promoter -1306 (rs243865) and -735 (rs2285053) genotypes in childhood leukemia risk. MATERIALS AND METHODS This case-control study included 266 patients and 266 age- and gender-matched healthy controls. The polymorphic sites of MMP-2 were genotyped by typical polymerase chain reaction-restriction fragment length polymorphism. RESULTS The CC, CT and TT of rs243865 genotype were 75.2, 23.7 and 1.1% in the case group and 69.2, 28.9 and 1.9% in the control group, respectively. The CT and TT genotypes caused a 0.75- and 0.55-fold increase in the risk of childhood leukemia, respectively. There was no differential distribution of rs2285053 genotypes. Allelic frequency analysis showed that the T allele of MMP-2 promoter -1306 and -735 conferred lower susceptibility than the C allele. CONCLUSION The MMP-2 promoter genotypes play a minor role in determining personal susceptibility to childhood leukemia among the Taiwanese.

Abstract
Purpose A growing body of evidence shows an association between DNA repair protein genotypes and susceptibility to various cancers. However, few studies have assessed the contribution of the genotype of XRCC3, a homologous repair gene, to the occurrence or prognosis of childhood acute lymphoblastic leukemia (ALL). In this study, we investigated the contribution of seven XRCC3 polymorphisms to childhood ALL. Patients and methods We recruited 266 patients with childhood ALL and 266 healthy controls. Genomic DNA was isolated from peripheral blood samples. The XRCC3 rs1799794, rs45603942, rs1799796, rs861530, rs28903081, rs861539, and rs3212057 polymorphic genotypes of each subject were determined through conventional polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) analysis. Results Genotypes with the rs861539 polymorphism were significantly associated with the risk of childhood ALL. The allelic distribution analyses suggested a significant association between the T allele at rs861539 with an increased risk of childhood ALL in the Taiwanese population. Polymorphic variants of XRCC3 at rs3212057 or rs28903081 did not exist in the study population. XRCC3 rs1799794, rs45603942, rs1799796, and rs861530 were not significantly associated with the risk of childhood ALL in the Taiwanese population. Conclusion Our findings suggest that XRCC3 genotypes with polymorphisms at rs861539 may play a role in determining individual susceptibility to childhood ALL in this Taiwanese population. The polymorphism may be a potential detector and predictor of childhood ALL.

Abstract
BACKGROUND/AIM Accumulated evidence has supported the notion that matrix metalloproteinase (MMP) genotypes are associated with the susceptibility of many types of cancers. However, few reports have studied the contribution of MMP genotypes to either diagnostic or prognostic potential in non-solid tumors such as leukemia. In this study, we firstly investigated the contribution of a polymorphism in the promoter region of MMP-8 (-799C/T) and two non-synonymous polymorphisms (Val436Ala and Lys460Thr) to childhood leukemia. PATIENTS AND METHODS In this study, 266 patients with childhood acute lymphoblastic leukemia (ALL) and 266 non-cancer control patients were collected and the genomic DNA was isolated from their peripheral blood. MMP-8 -799C/T, Val436Ala and Lys460Thr polymorphic genotypes of each subject were determined by the typical polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). RESULTS The results showed that the three polymorphisms were not significantly associated with an increased risk of childhood ALL in the overall investigated population. Furthermore, when the analyses were stratified by age and gender, no significant association between these genotypes and increased ALL risk was found. CONCLUSION Our findings suggest that the polymorphisms at MMP-8 -799C/T, Val436Ala and Lys460Thr may not play a major role in determining the personal susceptibility to childhood ALL in Taiwan.

Abstract
BACKGROUND/AIM The matrix metalloproteinases (MMPs) are important in inflammation and carcinogenesis, and the genotypic role of MMP7 has never been examined in leukemia to date. Therefore, in this study we aimed to evaluate the contribution of the genotypic variants in the promoter region of MMP7 (A-181G and C-153T) to childhood acute lymphoblastic leukemia (ALL) risk in Taiwan. MATERIALS AND METHODS In this case-control study, 266 patients with childhood ALL and 266 non-cancer controls were genotyped by polymerase chain reaction-restriction fragment length polymorphism methodology. RESULTS The distribution of AA, AG and GG for MMP7 promoter A-181G genotype was 83.5, 12.0 and 4.5% in the childhood ALL group and 89.8%, 9.4 and 0.8% in the non-cancer control group, respectively (p for trend=0.0134), significantly differentially distributed between childhood ALL and control groups. The comparisons in allelic frequency distribution also support the findings that G appears to be the risky allele in childhood ALL. In genotype and gender interaction analysis, it was found that boys carrying the MMP7 A-181G GG and AG+GG genotypes had 9.05- and 2.45-fold odds ratios (ORs) (p=0.0135 and 0.0142, respectively) for childhood ALL compared to those carrying wild-type AA genotype. But these differences were not found in girls. Analysis of genotype interaction with age of onset age showed those aged less than 3.5 years at onset carrying the GG or AG+GG genotypes also had elevated ORs of 8.79- and 2.04-fold (p=0.0150 and 0.0413, respectively) for childhood ALL, but there was no such difference for those having an age at onset of 3.5 years or more. CONCLUSION Our results indicate that the MMP7 A-181G genotype interacts with age and gender and may serve as an early and predictive biomarker for childhood ALL.

Abstract
Prostacyclin agonists that bind the prostacyclin receptor (IP) to stimulate cAMP synthesis are effective vasodilators for the treatment of idiopathic pulmonary arterial hypertension (IPAH), but this signaling may occur through nuclear peroxisome proliferator-activated receptor-γ (PPARγ). There is evidence of scant IP and PPARγ expression but stable prostanoid EP4 receptor (EP4) expression in IPAH patients. Both IP and EP4 functionally couple with stimulatory G protein (Gs), which activates signal transduction. We investigated the effect of an EP4-specific agonist on pulmonary arterial remodeling and its regulatory mechanisms in pulmonary arterial smooth muscle cells (PASMCs). Immunoblotting evealed IP, EP4, and PPARγ expression in human pulmonary arterial hypertension (PAH) and monocrotaline (MCT)-induced PAH rat lung tissue. Isolated PASMCs from MCT-induced PAH rats (MCT-PASMCs) were treated with L-902,688, a selective EP4 agonist, to investigate the anti-vascular remodeling effect. Scant expression of IP and PPARγ but stable expression of EP4 was observed in IPAH patient lung tissues and MCT-PASMCs. L-902,688 inhibited IP-insufficient MCT-PASMC proliferation and migration by activating PPARγ in a time- and dose-dependent manner, but these effects were reversed by AH-23848 (an EP4 antagonist) and H-89 [a protein kinase A (PKA) inhibitor], highlighting the crucial role of PPARγ in the activity of this EP4 agonist. L-902,688 attenuated pulmonary arterial remodeling in hypoxic PAH mice and MCT-induced PAH rats; therefore, we conclude that the selective EP4 agonist L-902,688 reverses vascular remodeling by activating PPARγ. This study identified a novel EP4-PKA-PPARγ pathway, and we propose EP4 as a potential therapeutic target for PAH.

Abstract
The aim of this study was to develop a task set based on personalized material for nostalgic experience, which could detect cognitive ability via a virtual experience system combined with Kinect somatosensory interactive operation applications without the user wearing any accessory input device. Fifty-nine subjects participated in the experiment. The receiver operating characteristic curve of the game system was statistically analyzed for determining the best cutoff-point in the cognitive function assessment. Correlation analysis and regression analysis were used to explore the correlations between the results and the clinical cognitive assessment scales. According to the MoCA scores, the results showed that the accuracy of the system was 86.4% in evaluating mild cognitive impairment. The system seems feasible and was strongly correlated with clinical cognitive assessment scales. We anticipate that daily use of our system could keep track of changes of cognitive function of the elderly in home life.

Abstract
Bipolar disorder (BD) is a severe mental illness that is characterized by chronicity, pervasive instability, and relatively high rates of recurrence and suicide. Current evidence supports that adverse circles among hereditary and genetic factors, neuroinflamation, and social rhythm constitute a crucial etiology. Pharmacological treatment is the first priority for BD patients during the acute stage. Pharmacological and psychosocial treatments should be combined during the maintenance stage in order to help patients self-manage medication, effectively control mood swings, enhance disease self-management and social functions, decrease the risks of relapse and re-hospitalization, and stabilize overall health. The present article firstly introduces the characteristics and etiological assumptions related to BD, the related evidence-based care models and their effects, and the early development of an evidence-based care model, the BalancingMySwing group, for BD patients in Taiwan. This article provides updated information to clinicians who are involved in caring for this population. Moreover, the existing data related to biological and psychosocial factors for BD in Taiwan is insufficient and developing individual-tailored psychosocial intervention is urgently needed. The authors hope that this article will elicit greater concern for this issue from policy decision-makers and healthcare providers.

Abstract
AIM Up-regulation of metalloproteinase (MMPs) proteins have been shown in various types of solid cancers and the genotype of MMP1 has been associated with the risk of solid cancers. However, the contribution of MMP1 genotype to leukemia has never been investigated to our knowledge. Therefore, in this study we aimed to evaluate the contribution of the genotypic variants in the promoter region of MMP1 to childhood acute lymphoblastic leukemia (ALL) risk in Taiwan. MATERIALS AND METHODS In this case-control study, 266 patients with childhood ALL and 266 non-cancer controls were genotyped by polymerase chain reaction-restriction fragment length polymorphism methodology. RESULTS The distribution of 2G/2G, 1G/2G and 1G/1G for MMP1 promoter rs1799750 genotype was 49.2%, 39.5% and 11.3% in the childhood ALL group and 36.8%, 43.6% and 19.5% in the non-cancer control group, respectively (p for trend=0.0046), significantly differentially distributed between childhood ALL and control groups. The carrier comparisons in dominant and recessive models also support the findings that 1G appears to be the protective allele in childhood ALL. In genotype and gender interaction analysis, it was found that boys carrying the MMP1 rs1799750 1G/2G or 1G/1G genotypes had lower odds ratios(ORs) of 0.68 and 0.43 [95% confidence intervals (CI)=0.47-0.98 and 0.26-0.73, p=0.0395 and 0.0013, respectively] for childhood ALL than those carrying the 2G/2G genotype. Analysis of genotype inaction with age of onset age showed those aged less than 3.5 years at onset carrying the 1G/2G or 1G/1G genotypes had lower ORs (0.0183 and 0.0004, respectively) for childhood ALL, but there was no such difference for those having an age at onset of 3.5 years or more. CONCLUSION Our results indicate that the MMP1 rs1799750 1G allele is a protective biomarker for childhood ALL.

Abstract
AIM Flap endonuclease 1 (FEN1) is one of the most important proteins in maintaining genome stability and preventing carcinogenesis. In recent years, the contribution of two variants of FEN1, rs174538 and rs4246215, regarding cancer risk have been investigated in lung, breast, liver, esophageal, gastric, colorectal cancer and glioma. However, it has not been revealed whether rs174538 and rs4246215 are associated with leukemia. Therefore, in the present study we aimed to evaluate the contribution of these genotypic polymorphisms in FEN1 to childhood acute lymphoblastic leukemia (ALL) risk in Taiwan. MATERIALS AND METHODS In total, 266 patients with childhood ALL and an equal number of recruited non-cancer controls were genotyped by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). RESULTS The FEN1 rs174538 genotype, but not rs4246215, was differently distributed between childhood ALL and control groups. The AG and AA of FEN1 rs174538 genotypes were significantly less frequently found in childhood ALL patients than in controls (odds ratio [OR]=0.68 and 0.48, 95%confidence intervals [CI]=0.47-0.98 and 0.24-0.82, respectively). As for gender, boys carrying the FEN1 rs174538 AG or AA genotype conferred lower ORs of 0.55 and 0.36 (95%CI=0.33-0.91 and 0.18-0.73, p=0.0053) for childhood ALL. Regarding age, those equal to or greater than 3.5 years of age at onset carrying the FEN1 rs174538 AG or AA genotype were of lower risk (ORs=0.53 and 0.32, 95%CI=0.31-0.90 and 0.15-0.70, p=0.0042). CONCLUSION The FEN1 rs174538 A allele is a protective biomarker for childhood ALL and this association is more significant in males and in patients at onset age of 3.5 years or older.

Abstract
AIM Lung cancer is the leading cause of cancer-related death worldwide. Interleukin-4 (IL-4) is a typical pleiotropic T helper 2 cytokine involved in immunology during carcinogenesis. The present study aimed at evaluating the contribution of IL-4 promoter T-1099G (rs2243248), C-589T (rs2243250), C-33T (rs2070874) genetic polymorphisms to the risk of lung cancer in Taiwan. MATERIALS AND METHODS The contributions of the promoter IL-4 polymorphic genotypes to lung cancer risk were investigated in 358 lung cancer patients and 716 age- and gender-matched healthy controls. In addition, the interaction between IL-4 and individual smoking status was also evaluated. RESULTS The percentages of CC, CT and TT for IL-4 C-589T genotypes were differentially represented as 69.0%, 26.5% and 4.5% in the lung-cancer patient group and 61.3%, 30.4% and 8.3% in the non-cancer control group, respectively (p=0.0156). The TT genotype carriers were of lower risk for lung cancer (odds ratio (OR)=0.48, 95% confidence interval (CI)=0.27-0.86, p=0.0106) than the CC genotype carriers. We also analyzed the allelic frequency distributions and the results showed that the T allele of IL-4 C-589T conducted a protective effect on lung cancer susceptibility (p=0.0022). On the contrary, there was no difference in the distribution of genotypic or allelic frequencies among patients and controls for the IL-4 promoter T-1099G and C-33T. CONCLUSION The TT genotype of IL-4 C-589T compared to the CC wild-type genotype may have a protective effect on lung cancer risk in Taiwan and may serve as an early detection and prediction marker.

Abstract
BACKGROUND Public attitudes toward mental illness influence the success with which patients reenter the community. An attitude instrument suitable to the Chinese cultural setting with good reliability and validity is essential to examining public attitudes toward mental illness. Exploring the perspectives of adolescents is relevant because most mental illness occurs during adolescence. PURPOSE This study developed and tested the psychometric quality of the Chinese-version Attitudes Toward Mental Illness (CAMI) scale among senior high school students. METHODS The original AMI was translated into Chinese using a back and forth translation method and its content validity was examined. A cross-sectional survey of 479 senior high school students was conducted to assess the construct validity, cross validity, and internal consistency of the CAMI. RESULTS The CAMI showed adequate content validity. The confirmatory factor analysis support: the appropriateness of CAMI's original two-factor structure of negative attitude and recovery outcomes after deleting items 9 and 11; the measurement of the negative perceptions of mentally ill patients and their risks to community; and the perceptions of recovery of mentally ill patients. The construct validity and cross validity are appropriate and the internal consistency of the total scale and two subscales are acceptable (Cronbach's α: .76, .75, .81). CONCLUSIONS / IMPLICATIONS FOR PRACTICE The reliability and validity of the CAMI is appropriate for the sample of senior high students in this study. Future studies should target a broader range of people in order to establish the reliability and validity of the scale in different groups and to build up empirical knowledge on public attitudes toward mental illness. The application of this scale is expected to contribute to the development of anti-stigma interventions and to the creation of friendly communities for mentally ill patients.

Abstract
Peptidylarginine deiminase type 2 (PADI2) deiminates (or citrullinates) arginine residues in protein to citrulline residues in a Ca2+-dependent manner, and is found in lymphocytes and macrophages. Vimentin is an intermediate filament protein and a well-known substrate of PADI2. Citrullinated vimentin is found in ionomycin-induced macrophage apoptosis. Citrullinated vimentin is the target of anti-Sa antibodies, which are specific to rheumatoid arthritis, and play a critical role in the pathogenesis of the disease. To investigate the role of PADI2 in apoptosis, we generated a Jurkat cell line that overexpressed the PADI2 transgene from a tetracycline-inducible promoter, and used a combination of 12-O-tetradecanoylphorbol-13-acetate and ionomycin to activate Jurkat cells. We found that PADI2 overexpression reduced the cell viability of activated Jurkat cells in1a dose- and time-dependent manner. The PADI2-overexpressed and -activated Jurkat cells presented typical manifestations of apoptosis, and exhibited greater levels of citrullinated proteins, including citrullinated vimentin. Vimentin overexpression rescued a portion of the cells from apoptosis. In conclusion, PADI2 overexpression induces apoptosis in activated Jurkat cells. Vimentin is involved in PADI2-induced apoptosis. Moreover, PADI2-overexpressed Jurkat cells secreted greater levels of vimentin after activation, and expressed more vimentin on their cell surfaces when undergoing apoptosis. Through artificially highlighting PADI2 and vimentin, we demonstrated that PADI2 and vimentin participate in the apoptotic mechanisms of activated T lymphocytes. The secretion and surface expression of vimentin are possible ways of autoantigen presentation to the immune system.

Abstract
Ornithine decarboxylase (ODC), the key enzyme of polyamine biosynthesis, has paradoxical roles in apoptosis. Our published papers show overexpression of ODC prevents the apoptosis induced by many cytotoxic drugs. Thapsigargin (TG) is an inhibitor of the sarcoplasmic/endoplasmic reticulum (ER) Ca(2+) ATPase (SERCA) pumps and causes ER stress-induced apoptosis. We used ODC overexpressing cell lines to examine whether overexpression of ODC inhibits TG-induced apoptosis. Our results indicated overexpression of ODC attenuated TG-induced apoptosis. Overexpression of ODC blocked procaspase-4 cleavage and phosphorylation of protein kinase-like ER-resident kinase (PERK), triggered by TG. It also attenuated the increase in CAAT/enhancer binding protein homologous protein (CHOP). Cells with overexpressed ODC had greater Bcl-2 expression. Overexpression of ODC preserved the expression of Bcl-2, inhibited the increase in Bak and stabilized mitochondrial membrane potential without the influences of TG. Cytochrome c release and down-stream caspase activation were blocked. That is, overexpression of ODC inhibits the mitochondria-mediated apoptotic pathway, induced by TG. Finally, overexpression of ODC maintains the protein and mRNA expression of SERCA. In conclusion, overexpression of ODC suppresses TG-induced apoptosis by blocking caspase-4 activation and PERK phosphorylation, attenuating CHOP expression and inhibiting the mitochondria-mediated apoptotic pathway.

Abstract
Ornithine decarboxylase (ODC), a tumor promoter, provokes cell proliferation, and inhibits cell death; but the mechanism involved in cell differentiation remains unknown. Herein, we examine whether it functions during macrophage-like differentiation. Previous studies reveal that ODC, a rate-limiting enzyme of polyamine biosynthesis, and polyamines are involved in restraining immune response in activated macrophage. By using 12-O-tetradecanoylphorbol-13-acetate (TPA)-differentiated human promyelocytic HL-60 and promonocytic U-937 cells, we discover that polyamines block the expression, secretion and activation of MMP-9. Meanwhile conventional expression of ODC represses tumor necrosis factor-alpha (TNF-alpha) expression and nuclear factor-kappaB (NF-kappaB) activation as well as MMP-9 enzyme activity. Following stimulation by TNF-alpha, the secretion of MMP-9 is restored in ODC-overexpressed cells. In addition, the NF-kappaB inhibitors (pyrrolidinedithiocarbamate, BAY-11-7082 and lactacystin) suppress the TPA-induced MMP-9 enzyme activity. Concurrently, both the irreversible inhibitor of ODC, alpha-difluoromethylornithine, and TNF-alpha could not recover MMP-9 activation following NF-kappaB inhibitor treatment in parental cells. Furthermore, ODC could directly inhibit and attenuate NF-kappaB DNA binding and transcriptional activation. Therefore, we suggest that ODC inhibits the TNF-alpha-elevated MMP-9 activation via NF-kappaB as TPA-induced macrophage-like differentiation and this interrupting mechanism may provide a new conceivable resolution why leukemia is poorly differentiated besides atypical growth.

Abstract
Curcumin, a well-known dietary pigment derived from the food flavoring turmeric (Curcuma longa) exhibits anti-proliferative, anti-inflammatory, and anti-oxidative activities. Recently, studies have shown that a chemopreventive effect of curcumin could be due to the hyperproduction of reactive oxygen species (ROS) inducing apoptosis in tumor cells. In our previous studies, ornithine decarboxylase (ODC) overexpression prevented tumor necrosis factor alpha (TNF-alpha)- and methotrexate-induced apoptosis via reduction of ROS. Furthermore, ODC is the rate-limiting enzyme in polyamine biosynthesis and a target for chemoprevention. In this study, we found that enzyme activity and protein expression of ODC were reduced during curcumin treatment. Overexpression of ODC in human promyelocytic leukemia HL-60 parental cells could reduce curcumin-induced apoptosis, which leads to loss of mitochondrial membrane potential (Deltapsi(m)), through reducing intracellular ROS. Moreover, ODC overexpression prevented cytochrome c release and the activation of caspase-9 and caspase-3 following curcumin treatment. These results demonstrate that curcumin-induced apoptosis occurs through a mechanism of down-regulating ODC and along a ROS-dependent mitochondria-mediated pathway.

Abstract
Peptidylarginine deiminase IV (PADI4) posttranslationally converts peptidylarginine to citrulline. It plays an essential role in immune cell differentiation and apoptosis. A haplotype of single-nucleotide polymorphisms (SNPs) in PADI4 is functionally relevant as a rheumatoid arthritis (RA) gene. It could increase enzyme activity leading to raised levels of citrullinated protein and stimulating autoantibody. Previously, our study showed that inducible PADI4 causes haematopoietic cell death. Herein, we further investigate whether RA risk PADI4 haplotype (SNP PADI4; S55G, A82V and A112G) and the increase of its enzymatic activity induce apoptosis. In the tetracycline (Tet)-On Jurkat T cells, ionomycin (Ion) only treatment didn't induce apoptosis however it promoted inducible PADI4-decreased cell viability and -enhanced apoptosis. Through in vitro and in vivo PADI enzyme activity assay, we demonstrated that PADI4 enzyme activity of SNP PADI4 was higher than RA non-risk PADI4 haplotype (WT PADI4). The effect of SNP PADI4-induced apoptosis was superior to WT PADI4. In addition, both Ion and SNP PADI4 synergistically provoked apoptosis were compared with both Ion and WT PADI4. Concurrently, in the conditionally inducible SNP PADI4 cells of Ion treatment-induced apoptosis, not only the expression of Bcl-xL was down-regulated and Bax up-regulated, but also cytochrome c was released from mitochondria to cytoplasm in significant amounts. Western blotting data showed the increase in apoptosomal caspase activation during programmed cell death in the inducible SNP PADI4 cells subsequent to Ion treatment. These data demonstrated that both SNP PADI4 increasing their enzyme activity could enhance apoptosis through the mitochondrial pathway and further provide a conceivable explanation in the pathogenesis of RA following the upregulation of PADI4 activity in its SNPs.

Abstract
BACKGROUND AND OBJECTIVE The expression of P-selectin on the surface of platelets and platelet-leucocyte conjugate formation are considered to be an indicator of platelet activation in thrombotic and inflammatory disease. Midazolam is a widely used sedative and anaesthetic induction agent. It may inhibit platelet aggregation and suppress interleukin-6 and -8 response in human leucocytes, but any effect on the adhesion of activated platelets to leucocytes remains obscure. We have examined the influence of midazolam on adenosine diphosphate (ADP)-induced platelet surface P-selectin expression and platelet-leucocyte aggregation in whole blood. METHODS Human whole blood was stimulated with 2 x 10(-5)M ADP in the presence of midazolam (3 x 10(-4) to 3 x 10(-6)M). Samples were stained with a fluorochrome-conjugated CD62P and CD41a antibody for detecting human platelet P-selectin antigens. The leucocyte subpopulations were separately gated and platelet-leucocyte aggregates were defined as cells found positive for CD45 and CD62P. All samples were analysed and were electronically separated into specific cell types (platelets, neutrophils, monocytes and lymphocytes) according to their typical forward/side scattering by flow cytometry. RESULTS Midazolam significantly inhibited ADP-induced platelet P-selectin expression and attenuated platelet-leucocyte aggregation (mainly in neutrophils and monocytes) in a dose-dependent manner with a maximum inhibitory effect at 3 x 10(-4)M (P < 0.01). CONCLUSIONS This study demonstrated that midazolam decreases the ADP-induced expression of platelet surface P-selectin and platelet-leucocyte aggregation.

Abstract
To convert high-solids organic wastes (3% w./w.) to high-value hydrogen, a full factorial experimental design was employed in planning the experiments for learning the effects of pH and hydraulic retention time (HRT) on the hydrogen production in a chemostat reactor using waste yeast obtained from beer processing wastes. For determining which experimental variable settings affect hydrogen production, predictive polynomial quadratic equation and response surface methodology were employed to determine and explain the conditions required for high-value hydrogen production. Experimental results indicate that a maximum hydrogen production rate of 460 mL/gVSS/d was obtained at pH = 5.8 and HRT = 32 hours. Moreover, hydrogenase targeted RT-PCR results indicate that Clostridium thermocellum and Klebsiella pneumoniae predominated.

Abstract
Can individual cells, including live cells, be imaged using hard x rays? Common wisdom until now required sophisticated staining techniques for this task. We show instead that individual cells and cell details can be detected in culture solution and tissues with no staining and no other contrast-enhancing preparation. The sample examined can be much thicker than for many other microscopy techniques without sacrificing the capability to resolve cells. The key factor in our approach is the use of a coherent synchrotron source and of contrast mechanisms based on the refractive index. The first successful tests were conducted on a variety of cell systems including skin and internal leaf cells, mouse neurons, rabbit fibroblast cells, and human tumor cells.

Abstract
Methotrexate pneumonitis is an unpredictable and life-threatening side effect of methotrexate therapy. Early diagnosis, cessation of methotrexate, and treatment with corticosteroids and/or cyclophosphamide are important in the management of patients with methotrexate pneumonitis. Methotrexate pneumonitis has not been reported in patients of Chinese ethnicity. We report a case of methotrexate pneumonitis in a Taiwan patient with rheumatoid arthritis who presented with acute nonproductive cough, dyspnea, fever, severe hypoxemia, and rapid progression to respiratory failure. Chest roentgenogram demonstrated bilateral diffuse interstitial and alveolar infiltration. Thoracoscopic biopsy with wedge resection of the upper lobe of the right lung was performed and the histologic findings of the biopsy specimen were consistent with bronchiolitis obliterans with organizing pneumonia. Rapid improvement of methotrexate pneumonitis was achieved after pulse therapies of methylprednisolone and cyclophosphamide and daily use of prednisolone.

Abstract
To determine the roles of different members of the family of B cell lymphoma protooncogene (Bcl-2) in relation to neurotoxin-induced neuronal degeneration, the pattern of the expression of a number of molecules of the Bcl-2 family was studied immunocytochemically in the retinas of C57BL/6J mice after intraperitoneal (IP) injection of 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP). Three days to 12 weeks after MPTP treatment, a detectable reduction of tyrosine hydroxylase immunoreactivity in the amacrine cells was observed, with an increase of Bcl-2 expression in the Müller glial cells, and a de novo expression of Bad and Bax in the retinal ganglion cells, optic nerve fibers and plexiform layers. In contrast, a slight decrease of Bcl-x(L) immunoreactivity in the retinal ganglion cells was observed, whereas Bcl-x(S/L) immunoreactivity was increased slightly in the retinas of MPTP-treated mice compared with that of the controls. In animals that received MPTP injection, an increase in immunostaining of GFAP, glutamine synthetase, and Mac-1 (CD11b) in astrocytes, Müller cells, and microglia was invariably observed, indicating an activation or dysfunction of retinal glial cells. These findings are consistent with the current view that glial dysfunction is important in mediating the cytotoxic effect of a variety of neurotoxic molecules, including MPTP, and that different members of Bcl-2 family may have different roles as far as neuronal degeneration or neuroprotection is concerned.

Abstract
In the electrodeposition of metals, a widely used industrial technique, bubbles of gas generated near the cathode can adversely affect the quality of the metal coating. Here we use phase-contrast radiology with synchrotron radiation to witness directly and in real time the accumulation of zinc on hydrogen bubbles. This process explains the origin of the bubble-shaped defects that are common in electrodeposited coatings.

Abstract
We investigated whether single injection of 1-methyl-4-phenyl-1,2,3,6- tetrahydropyridine (MPTP) (20 mg/kg) will alter the expression of pro-apoptotic genes, namely, the c-fos, c-jun, and bax, in the striatum, cortex, and cerebellum of adult male C57BL/6 mice using reverse transcription-polymerase chain reaction assay. Injection of MPTP induced a transient decrease in the content of tyrosine hydroxylase estimated by the immunoreactivity in the striatum, which completely recovered 14 day after injection. A rapid but transient up-regulation of c-fos and c-jun genes occurred an hour after MPTP-injection, and a delayed but persistent up-regulation of bax gene expression occurred 3 day after injection. The up-regulation of these genes was present in all the examined brain regions. This result suggests that MPTP, at a low dose causing transient degeneration in the striatum, is capable of triggering two genetic pathways related to the generation of apoptosis in both dopaminergic and non-dopaminergic systems in the mouse brain.

Abstract
Photon activation of indium foils is proposed as a dosimetry technique for high dose rate measurements in a 60Co irradiation facility. The irradiated indium nuclei may be raised to its metastable isomers of 113mIn and 115mIn. The isomer 115mIn, with appreciable induced radioactivity, was selected for dose-rate measurements. Based on the photon flux distribution and the derived dose rates, which were simulated by the MCNP code, the dependence of dose rate measurement sensitivity of indium foils with respect to photon energy at various irradiation distances is described. For practical uses, the radioactivity of 115mIn was linearly related to the dose rate response at the specified irradiation positions. By comparing with a calibrated dosimetry system, the measurement deviation of the indium dosimeter, over dose rates ranging from 10 to 10(4) Gy/h, was evaluated and exhibited an uncertainty of +/- 7%. Other related characteristics including measurement sensitivity and range, linearity with respect to the variation of dose rate, and limitations of the indium dosimeter were evaluated to justify it as an alternative for monitoring dose rate in an irradiation field.

Abstract
Polychlorinated biphenyls (PCBs) with the liable 2,3,6-substitution are important components of certain commercial mixtures and frequently detected in biota, but little is known about their enzyme induction abilities and possible endocrine-disrupting effects. CB 132 (2,2',3,3',4,6'-hexachlorophenyl) and CB 149 (2,2'3,4',5',6-hexachlorophenyl) were investigated in weanling female rats dosed intraperitoneally on days 21 and 22 and killed on day 24 of age. Uterotropic response, serum thyroid hormone, and hepatic enzyme induction were examined in prepubertal female rats treated with these two environmentally relevant 2,3,6-substituted chlorobiphenyl (CB) congeners from 8 mg/kg to 96 mg/kg. The readily metabolized CB 132 did not cause any significant increase in all endpoints measured in the present study. On the other hand, CB 149 was a weak PROD and BROD inducer and a modest depleter of serum thyroxine in prepubertal female rats. The finding of thyroid hormone disruption by CB 149 may lead to biologically significant neurobehavioral and neurochemical changes in developing animals via milk lactation.

Abstract
A 34-year-old male laboratory worker suffered from asthenospermia and fertility problems. He was suspected of having been exposed to solvents used at work due to a malfunction of the ventilation system in his laboratory from August 1996 to April 1997. A laboratory walk-through and air and bulk sample collection were performed to determine the possible exposure levels of chemical hazards in his job. The scenario was reconstructed to simulate the worker's previous exposure during the ventilation shutdown period. It was found that the worker was possibly exposed to chloroform at levels of 10 or 50 times higher than the permissible exposure limit or the threshold limit value of 2 hr/day, 5.5 days/week, and 4.25 weeks/month for 8 months. Because chloroform is known to be spermatotoxic, the possibility of chloroform causing the worker's asthenospermia cannot be ruled out. Further study on spermatotoxicity of chloroform is warranted.

Abstract
BACKGROUND, AIMS Actinobacillus actinomycetemcomitans (Aa) has been implicated as the putative micro-organism for localized juvenile periodontitis (LJP). The most distinct clinical features of LJP include severe angular bony defects of the mesial sides of permanent first molars and the onset of disease during puberty. Currently, no large-scale studies have been performed which address the change in detection rates of Aa on the mesial sides of permanent 1st molars following eruption and up to puberty. METHOD In this study, subgingival plaque samples were taken from the mesial pockets of 2 randomly selected permanent 1st molars from 328 primary school children and 50 adult staff, and analyzed by polymerase chain reaction (PCR) to detect Aa. RESULTS The results showed a 5.5% prevalence rate of Aa which increased after the eruption of 1st molars and peaked near puberty. There were no significant differences in the detection rates of Aa among different groups in terms of gender, plaque index (PII), and gingival index (GI); however, the higher detection rates of Aa were significantly associated with increased probing depths at p<0.05. CONCLUSION PCR analysis of the subgingival plaques demonstrated a prevalence of Aa which peaked near puberty, suggesting that Aa may be important for LJP in Taiwan.

Abstract
It has been assumed that there is a relationship between periodontal diseases and diabetes mellitus, however the putative periodontal microorganisms in non-diabetes mellitus (non-DM) individuals and non-insulin-dependent diabetes mellitus (NIDDM) patients have not been well studied. In this study, the detection rates of 5 putative periodontal pathogens: Actinobacillus actinomycetemcomitans, Porphyromonas gingivalis, Eikenella corrodens, Treponema denticola, and Candida albicans by polymerase chain reaction (PCR) between NIDDM and non-DM adults were compared. A total of 246 adults were randomly recruited and periodontal parameters including: plaque index (P1I), gingival index (GI), probing depth (PD) and attachment level (AL) were recorded. Subgingival plaque samples were collected by sterile curettes from the most diseased and healthy sites based on PD and AL. The differences in periodontal parameters and microbiological data in healthy and diseased sites between non-DM and NIDDM patients were compared by chi-square analysis. The results showed no significant differences in age, gender, GI, P1I, PD, and prevalence of the 5 microorganisms between the NIDDM and the non-diabetic groups. However, except for A. actinomycetemcomitans, the prevalence of the periodontal microorganisms tested was significantly higher (p <0.001) in diseased sites than in the healthy sites in both groups. The P1I, GI, PD and AL were significantly higher in T. denticola positive sites than in negative sites. The results suggested that P. gingivalis, T. denticola, E. corrodens and C. albicans may play important roles in the periodontitis of both NIDDM and non-DM individuals, however the etiology of periodontitis in both groups may not be different from each other.

Abstract
It has been proposed that a LiF thermoluminescence dosemeter (TLD) is used as a gamma dosemeter in a water phantom irradiated with the BNCT facility at THOR. Based on the TLD neutron sensitivity and neutron fluxes in the water phantom, which were simulated by the MCNP code, TLD-700 was chosen as a gamma dosemeter in this report. For the correction of the neutron influence on TLD-700, the thermal neutron sensitivity to TLD-700 was investigated with MCNP simulation and the thermal neutron flux was measured with gold foils using the cadmium difference technique. The correction to the neutron influence on the TLD was established on the TLD thermal neutron sensitivity. the thermal neutron flux, and the conversion factor from energy deposition in the TLD to the TLD response. By comparing the experimental data with the thermal neutron influence correction, these data are in very good agreement with the MCNP predictions.

Abstract
7-Methylguanosine (m(7)G), also known as the mRNA "cap", is used as a molecular tag in eukaryotic cells to mark the 5' end of messenger RNAs. The mRNA cap is required for several key events in gene expression in which the m(7)G moiety is specifically recognized by cellular proteins. The configurations of the m(7)G-binding pockets of a cellular (eIF4E) and a viral (VP39) cap-binding protein have been determined by X-ray crystallography. The binding energy has been hypothesized to result from a pi-pi stacking interaction between aromatic residues sandwiching the m(7)G base in addition to hydrogen bonds between the base and acidic protein side chains. To further understand the structural requirements for the specific recognition of an m(7)G mRNA cap, we determined the effects of amino acid substitutions in eIF4E and VP39 cap-binding sites on their affinity for m(7)GDP. The requirements for residues suggested to pi-pi stack and hydrogen bond with the m(7)G base were examined in each protein by measuring their affinities for m(7)GDP by fluorimetry. The results suggest that both eIF4E and VP39 require a complicated pattern of both orientation and identity of the stacking aromatic residues to permit the selective binding of m(7)GDP.

Abstract
Large-scale poisoning occurred in central Taiwan in 1979 from ingestion of cooking oil contaminated by polychlorinated biphenyls (PCBs) and polychlorinated dibenzofurans. To determine whether in-utero exposure to these chemicals alters reproductive function, all prenatally exposed boys and appropriate controls were contacted for medical examination in 1998. Sperm of exposed children have increased abnormal morphology, reduced motility, and reduced capacity to penetrate hamster oocytes. Whether this will cause reduced fecundity, and how these effects can be extrapolated to the general population exposed to background levels of PCBs and dioxin-like chemicals, warrants further investigation.
