Abstract
BACKGROUND The integrity of the gut barrier in patients with inflammatory bowel disease is known to be impaired but the exact mechanisms remain mostly unknown. SHANK3 mutations are associated with autism, and patients with autism are known to have higher proportions of inflammatory bowel disease. Here, we explore the role of SHANK3 in inflammatory bowel disease, both in vivo and in vitro. METHODS Dextran sulfate sodium colitis was induced in SHANK3 knockout mice. Transepithelial electrical resistance, paracellular permeability, and Salmonella invasion assays were used to evaluate epithelial barrier function, in vitro and in vivo. Expression of tight junction proteins, protein kinases, and MAP kinase phosphorylation changes were analyzed by immunoblotting after overexpression or knockdown of SHANK3 expression. SHANK3 expression in intestinal tissue from patients with Crohn's disease was analyzed by quantitative polymerase chain reaction and immunohistochemistry. RESULTS SHANK3 knockout mice were more susceptible to dextran sulfate sodium. SHANK3 knockout resulted in a leaky epithelial barrier phenotype, as demonstrated by decreased transepithelial electrical resistance, increased paracellular permeability, and increased Salmonella invasion. Overexpression of SHANK3 enhanced ZO-1 expression, and knockdown of SHANK3 resulted in decreased expression of ZO-1. Regulation of ZO-1 expression by SHANK3 seems to be mediated through a PKCε-dependent pathway. SHANK3 expression correlated with ZO-1 and PKCε in colonic tissue of patients with Crohn's disease. CONCLUSIONS The expression level of SHANK3 affects ZO-1 expression and the barrier function in intestinal epithelial cells. This may provide novel insights in Crohn's disease pathogenesis and treatment.

Abstract
BACKGROUND The incidence of nasopharyngeal carcinoma (NPC) is higher in Chinese than in Caucasian populations. Genetic, viral, and lifestyle factors may explain these ethnic differences in the incidence of NPC. In the present study, we examined the familial aggregation, heritability, and relative risks (RRs) of NPC using a nationwide database in Taiwan. METHODS A population-based family study was conducted using the Taiwan National Health Insurance Research Database. Participants included all individuals (N=23,422,955) registered with that database in 2013; of these, 17,653 had NPC. Among them, 47.45%, 57.45%, 47.29%, and 1.51% had a parent, child, sibling, and twin, respectively, with NPC. RESULTS Among the approximately 23 million Taiwan NHI beneficiaries in 2013, the relative risks (RRs) (95% confidence intervals) for NPC were 34.46 (5.12-231.77) for twins of the patients, 9.23 (6.34-13.43) for siblings, 3.80 (2.97-4.86) for parents, 3.74 (2.60-5.37) for offspring, and 1.78 (1.16-2.74) for spouses without genetic similarity. The mean age of onset in first-degree relative-affected NPC patients was 35.5years compared to 39.0years for NPC patients without affected first-degree relatives (p≤0.0001). Using a threshold liability model, the accountability for phenotypic variance of NPC was estimated to be 61.3% for genetic factors (heritability), 13.9% for shared environmental factors, and 24.8% for non-shared environmental factors. The probability of a patient with NPC to be sporadic was 82.8%. CONCLUSION This population-based analysis suggested a strong familial tendency in the development of NPC. Screening of first-degree relatives of NPC patients is recommended, particularly in endemic regions.

Abstract
This study assesses interactions of tumor necrosis factor α (TNF-α) gene polymorphisms with C-reactive protein (CRP) or lymphotoxin α (LTA) gene on serum CRP and TNF-α levels and handgrip strength. Eleven single nucleotide polymorphisms (SNPs), including rs2794520, rs1205, rs1130864, rs1800947, and rs3093059 in CRP; rs1799964, rs1800629, and rs3093662 in TNF-α; and rs2239704, rs909253, and rs1041981 in LTA, were genotyped in 472 unrelated elders (mean age 73.8 years). Among elders with TNF-α rs1799964 AA genotype, adjusted mean difference for handgrip strength decreased by -2.60 (-4.82, -0.38) and -2.51 kg (-4.75, -0.28) for LTA rs909253 and rs1041981 in women and by -2.39 kg (-3.98, -0.81) for CRP rs3093059 in men. Among elders with TNF-α rs1799964 AA genotype, adjusted mean ratios for hs-CRP levels increased by 2.32 (1.38, 3.90) and 2.27 (1.35, 3.84) for both CRP rs909253 and rs1041981 in women. The A-A-C LTA haplotype was associated with TNF-α levels that were 1.55 times higher than those of the C-G-A haplotype (P = 0.005). The joint effects of SNPs (the rs1800947 or rs3093059 of CRP, rs1799964 or rs1800629 of TNF-α, and rs909253 or rs1041981 of LTA) and physical inactivity appeared to have greater magnitude of decreased handgrip strength than main effects of these SNPs and physical inactivity. Our data showed that significant interactions of TNF-αrs1799964 and LTA rs909253 were observed. Moreover, joint effects of these CRP, TNF-α, and LTA risk alleles with physical inactivity in elders were observed, suggesting that physical activity may modulate effects of genotypes on handgrip strength.

Abstract
The aim of this study was to evaluate the interacted association between EDNRA and EDN1 polymorphisms and gender, regular exercise, and obesity status on carotid intima media thickness (IMT) in community- dwelling subjects of the Taichung Community Health Study. Five single-nucleotide polymorphisms (SNPs rs1395821, rs1878406, rs5333, rs1800541, and rs5370) of the EDNRA and EDN1 gene were examined in 480 participants from 160 families. The IMT protocol involves scanning the common carotid arteries (CCAs), the carotid bifurcations (bulb), and the origins (first 1 cm) of the internal carotid arteries (ICAs). Generalized linear models with a generalized estimating equation were employed to consider the dependence among family members. After multivariate adjustment, the effects of interactions between EDNRA and EDN1 gene with gender, obesity, and exercise were observed. For gene-gender interaction on CCA IMT, the adjusted mean for men carrying the GA/GG genotype of EDNRASNP rs1878406 was 1.18 times higher than that for men carrying the AA genotype (95% CI: 1.01, 1.37). As for bulb and ICA IMT, the adjusted mean values for women carrying the AC/AA genotype of EDN1 rs5370 was lower than those carrying the CC genotype: 0.89, [0.82, 0.98]; and 0.90 [0.83, 0.99], respectively. We did observe significant effects of EDNRA SNPs rs1395821 and rs5333 in individuals who regularly exercised. A significantly lower adjusted mean in CCA IMT for non-obese individuals carrying EDNRA SNP rs5333 was observed (0.92 [0.86, 0.99]) compared with non-obese individuals carrying the AA genotype. This study first reported significant interactions of EDNRA and EDN1 polymorphisms with gender, regular exercise, and obesity on carotid IMT in Han Chinese participants.

Abstract
Background Diabetic nephropathy (DN) has become one of the most common causes of end-stage renal disease (ESRD) in many countries, such as 44.5% in Taiwan. Previous studies have shown that there is a genetic component to ESRD. Studies attempting to determine which genetic variants are related to DN in Han Chinese are limited. A case–control study was conducted to identify DN susceptibility variants in Han Chinese patients with type 2 diabetes. Results We included 574 unrelated type 2 diabetes patients (217 DN cases and 357 controls), who were genotyped using Illumina HumanHap550-Duo BeadChip. In single-SNP association tests, the SNPs rs11647932, rs11645214, and rs6499323 located at 16q22.1 under the additive-effect disease model were significantly associated with an approximately 2-fold increased risk of DN. In haplotype association tests, identified haplotypes located in the chromosome 16q22.1 region (containing ST3GAL2, COG4, SF3B3, and IL34 genes) raised DN risk. The strongest association was found with haplotype rs2288491-rs4985534-rs11645214 (C-C-G) (adjusted odds ratio [AOR] 1.93, 95% confidence interval [CI] 1.83-2.03, p = 6.25 × 10−7), followed by haplotype rs8052125-rs2288491-rs4985534-rs11645214 (G-C-C-G) (AOR 1.92, 95% CI 1.82-2.02, p = 6.56 × 10−7), and haplotype rs2303792-rs8052125-rs2288491-rs4985534-rs11645214 (A-G-C-C-G) (AOR 1.91, 95% CI 1.81-2.01, p = 1.15 × 10−6). Conclusions Our results demonstrate that the novel SNPs and haplotypes located at the 16q22.1 region may involve in the biological pathways of DN in Han Chinese patients with type 2 diabetes. This study can provide new insights into the etiology of DN.

Abstract
BACKGROUND & AIMS To date, only one gene (TNFSF15) has been identified and validated as a Crohn's disease (CD)-associated gene in non-Caucasian populations. This study was designed to identify novel CD-associated single nucleotide polymorphisms (SNPs)/genes and to validate candidate genes using a functional assay. METHODS SNPs from 16 CD patients and 16 age- and sex-matched control patients were analyzed using Illumina platform analysis. Subsequently, we expanded the study and followed 53 CD patients and 41 control patients by Sequenom MassArray analysis. Quantitative PCR and immunohistochemical staining were performed to assess mRNA and protein expression of the candidate gene on tissue isolated from CD patients. Genotype was correlated with CD phenotypes. Finally, the candidate gene was cloned and its effect on NF-κB activity assessed using a reporter luciferase assay. RESULTS SLCO3A1 (rs207959) reached statistical significance in the first-stage analysis (P = 2.3E-02) and was further validated in the second-stage analysis (P = 1.0E-03). Genotype and phenotype analysis showed that the rs207959 (T) allele is a risk allele that alters SLCO3A1 mRNA expression and is associated with intestinal perforation in CD patients. Higher levels of mRNA and protein expression of SLCO3A1 were seen in CD patients compared with the control group. Overexpression of SLCO3A1 induced increased NF-κB activity and increased phosphorylation of P65, ERK, and JNK. Nicotine augmented the activation of NF-κB in the presence of SLCO3A1. CONCLUSIONS SLCO3A1, a novel CD-associated gene, mediates inflammatory processes in intestinal epithelial cells through NF-κB transcription activation, resulting in a higher incidence of bowel perforation in CD patients.

Abstract
BACKGROUND Numerous efforts have been made to elucidate the etiology and improve the treatment of lung cancer, but the overall five-year survival rate is still only 15%. Although cigarette smoking is the primary risk factor for lung cancer, only 7% of female lung cancer patients in Taiwan have a history of smoking. Since cancer results from progressive accumulation of genetic aberrations, genomic rearrangements may be early events in carcinogenesis. RESULTS In order to identify biomarkers of early-stage adenocarcinoma, the genome-wide DNA aberrations of 60 pairs of lung adenocarcinoma and adjacent normal lung tissue in non-smoking women were examined using Affymetrix Genome-Wide Human SNP 6.0 arrays. Common copy number variation (CNV) regions were identified by ≥30% of patients with copy number beyond 2 ± 0.5 of copy numbers for each single nucleotide polymorphism (SNP) and at least 100 continuous SNP variant loci. SNPs associated with lung adenocarcinoma were identified by McNemar's test. Loss of heterozygosity (LOH) SNPs were identified in ≥18% of patients with LOH in the locus. Aberration of SNP rs10248565 at HDAC9 in chromosome 7p21.1 was identified from concurrent analyses of CNVs, SNPs, and LOH. CONCLUSION The results elucidate the genetic etiology of lung adenocarcinoma by demonstrating that SNP rs10248565 may be a potential biomarker of cancer susceptibility.

Abstract
How to report and summarize a user's health or wellness status from the Electronic Health Records (EHR) is a important topic since a well-designed health report can provide not only a valued information source for users to exam their physical health status but also a guidance to a better health level. Existing health reports are not totally satisfying and easily bores a user by words and numeral data in them. Facial complexion is one of important indicator in the clinical diagnosis. The pathological changes of health status could often be diagnosed by inspecting the changes of facial complexion. Based on this facial complexion idea, a visualized health report, which reversely visualizes a user's health status directly on his/her outside appearance, is proposed to provide a better alternative than conventional text-based report. Due to its unique characteristic, the proposed visualized health information and guidance is expected to provide valued personalized health information and also effectively encourage users toward healthier lifestyle.

Abstract
Effective personal dietary guidelines are essential for health management and prevention of chronic diseases. A key factor toward a successful diet planning is an individual's food preference instead of dogmatic nutrition pattern since it is unlikely that an individual would accept the meal plan merely based on the nutrition supplements. However, the extraction of personal preference is definitely not a trivial matter. The objective of this research is to achieve nutrient-balanced food recommendations for each individual, while considering individual's preferences and requirements at the same time. To reach this goal, we present the k-relative learning technique for semi-automatically extracting users' preferences in a more efficient and effective manner. Comparing to conventional methods, the proposed system can not only reveal users' opinions about foods more fairly but also save lots of labeling efforts during the training data collection stage. In addition, a smarter feedback mechanism is also proposed to enable a more pleasant experience of the user-system interaction. The resulted system is thus expected to improve users' diet habit and compliance with healthier lifestyle.

Abstract
X-ray tomography is performed to acquire 3D images of crumpled aluminum foils. We develop an algorithm to trace out the labyrinthian paths in the three perpendicular cross sections of the data matrices. The tangent-tangent correlation function along each path is found to decay exponentially with an effective persistence length that shortens as the crumpled ball becomes more compact. In the meantime, we observed ordered domains near the crust, similar to the lamellae phase mixed by the amorphous portion in lyotropic liquid crystals. The size and density of these domains grow with further compaction, and their orientation favors either perpendicular or parallel to the radial direction. Ordering is also identified near the core with an arbitrary orientation, exemplary of the spontaneous symmetry breaking.

Abstract
Conventional image copy detection research concentrates on finding features that are robust enough to resist various kinds of image attacks. However, finding a globally effective fealure is difficult and, in many cases, domain dependent. Instead of imply extracting features from copyrighted images directly, we propose a new framework called the extended feature set for detecting copies of images. In our approach, virtual prior attacks are applied to copyrighted images to generate novel features, which serve as training data. The copy-detection problem can be solved by learning classifiers from the training data, thus, generated. Our approach can be integrated into existing copy detectors to further improve their performance. Experiment results demonstrate that the proposed approach can substantially enhance the accuracy of copy detection.

Abstract
A new herpesvirus-like DNA sequence (KSHV) has been recently identified in Kaposi's sarcoma (KS) from patients with AIDS and non-AIDS patients. To verify the specificity of the association of this new viral DNA with KS, a total of 155 cases of benign and malignant vascular neoplasms sharing similar histogenesis of endothelial derivation were analyzed for the presence of this KSHV sequence using the published 330-233 primers by polymerase chain reaction (PCR). The results revealed that all 17 cases of KS, both AIDS and non-AIDS, were positive for this KSHV, whereas the remaining 138 cases of vascular lesions other than KS, including 15 cases of angiosarcoma, showed negative reaction. These results confirm and extend the previous observation that this KSHV sequence is specifically associated with KS and is a reliable diagnostic marker to distinguish KS, particularly at its early stage, from other vascular lesions.

Abstract
Binding of trichloromonofluoromethane, dichlorodifluoromethane, and dichlorotetrafluoroethane was studied in aqueous 5% human albumin solution, using the partition coefficient method in sealed serum bottles. The partition coefficient and the fraction of fluorocarbons bound were highly dependent on fluorocarbon concentrations. The average binding sites per molecule of albumin were 2.17, 0.30, and 0.42 and the binding association constants were 1.11 X10-3, 1.73 X10-3, and 5.06X10-3 M-minus 1, respectively. At the lowest concentration studied, 62.3, 25.5, and 65.6% were found bound to albumin, respectively. This appears to represent the first extensive study on any gas-albumin interaction.

Abstract
Binding of dichlorotetrafluoroethane (F 114) with bovine albumin was studied at 37, 20.5 and 5 C. It was found that at the total concentration of 0.4 x 10-3 M of F 114 in the 5-percent protein solution, 50, 51 and 55% of them, respectively, were in bound form at the temperatures indicated above. The termodynamic data found for the F 114-bovine albumin interaction in the temperature range studied were: deltaG = -3.44 to -4.11 Kcal/mol. deltaS =20.40 to 20.45 e.u., and deltaH =2.23 Kcal/mol. It is postulated that the large positive entropic change associated with a sizable positive enthalpy change indicates that the breaking of iceberg water stucture and slight unfolding of albumin molecule are involved in the interaction.
