Abstract
In this study, the co-infection of Torque teno sus virus (TTSuV) and porcine circovirus type 3 (PCV3) was reported. One hundred and ten of 132 (83.3%) PCV3-positive samples were co-infected with Torque teno sus virus 1 (TTSuV1). Ninety-four of 132 (71.2%) PCV3-positive samples were co-infected with Torque teno sus virus 2 (TTSuV2). Sixty-six of 132 (50.0%) of PCV3-positive samples were co-infected with both TTSuV1 and TTSuV2. There were no clinical signs of infection in pigs that were both PCV3-positive and PCV2-negative, in either multiparous sows or live-born infants. The high co-infection rate provides valuable information for the further study of the pathological correlation between PCV3 and TTSuVs.

Abstract
Intramuscular fat (IMF) content is a key aspect of pork quality. Elucidation of intramuscular adipocyte regulation mechanisms is important for improving IMF content. Intramuscular adipocytes are dispersed among muscle fibers, so they are inclined to be affected by muscle-derived factors. Interleukin-15 is a major muscle-secreted factor. In this study, the genetic and physiological impacts of IL15 on adipogenesis is investigated. The promoter region of IL15 was scanned by comparative sequencing using two DNA pools of high- and low-IMF individuals. Two SNPs, c.-342C>T (ss2137497757) and c.-334G>A (ss2137497756) (the translation start site is designated as +1), were identified with reverse allele distribution in these two groups. Genotyping by allele-specific PCR revealed that the two SNPs were completely linked. The IMF content of TA/TA individuals was lower than that for CG/CG ones, whereas the IL15 expression level was higher in T-A/T-A individuals. Luciferase assaying also revealed that the T-A haplotype promoter had higher transcription activity. Meanwhile, the effect of interleukin-15 on adipocyte differentiation was further assessed in vitro. Results showed that interleukin-15 suppressed preadipocyte proliferation in a dose-dependent manner. The cell cycle of preadipocytes was arrested, and apoptosis was induced. Oil Red O staining and triglyceride quantification indicated that adipocyte differentiation was also inhibited by interleukin-15. The mRNA levels of PPARG and FABP4 decreased markably upon interleukin-15 treatment. Taken together, we identified two completely linked SNPs in the porcine IL15 promoter region that could alter IL15 transcription activity. As interleukin-15 can inhibit porcine adipocyte differentiation, these promoter mutations could affect IMF deposition by producing differential levels of muscle-derived interleukin-15.

Abstract
Numerous studies have been conducted to investigate genetic diversity, origins and domestication of donkey using autosomal microsatellites and the mitochondrial genome, whereas the male-specific region of the Y chromosome of modern donkeys is largely uncharacterized. In the current study, 14 published equine Y chromosome-specific microsatellites (Y-STR) were investigated in 395 male donkey samples from China, Egypt, Spain and Peru using fluorescent labeled microsatellite markers. The results showed that seven Y-STRs-EcaYP9, EcaYM2, EcaYE2, EcaYE3, EcaYNO1, EcaYNO2 and EcaYNO4-were male specific and polymorphic, showing two to eight alleles in the donkeys studied. A total of 21 haplotypes corresponding to three haplogroups were identified, indicating three independent patrilines in domestic donkey. These markers are useful for the study the Y-chromosome diversity and population genetics of donkeys in Africa, Europe, South America and China.

Abstract
Human enterovirus 71 (EV71) is the major causative agent of hand, foot, and mouth disease (HFMD), particularly in infants and children below 4 years of age. Shikonin is a bioactive compound with anti-inflammatory, antiviral, and antibacterial activities derived from the roots of the Chinese medicinal herb Lithospermum erythrorhizon. This study aimed to examine the antiviral activity of PMM-034, a shikonin ester derivative, against EV71 in rhabdomyosarcoma (RD) cells. Cytotoxicity of PMM-034 on RD cells was determined using WST-1 assay. Dose- and time-dependent effects of PMM-034 on EV71 replication in RD cells were determined using plaque reduction assay. mRNA expression levels of EV71/VP1 and pro-inflammatory cytokines (IL-1β, IL-6, IL-8, and TNF-α) were determined by real-time RT-PCR, and EV71/VP1 and phospho-p65 protein expressions were determined by western blot analysis. PMM-034 exhibited only weak cytotoxicity against RD cells. However, PMM-034 exhibited significant antiviral activity against EV71 in RD cells with 50% inhibitory concentration of 2.31 μg/mL. The VP1 mRNA and protein levels were significantly reduced in cells treated with PMM-034. Furthermore, relative mRNA expression levels of IL-1β, IL-6, IL-8, and TNF-α significantly decreased in the cells treated with PMM-034, while the phospho-p65 protein expression was also significantly lower in the treated cells. These results indicated that PMM-034 suppressed the expressions of pro-inflammatory cytokines in RD cells, exhibiting antiviral activity against EV71, as evidenced by the reduced VP1 mRNA and protein levels in PMM-034-treated cells. Thus, PMM-034 is a promising candidate for further development as an EV71 inhibitor.

Abstract
PURPOSE To compare the refractive outcome of eyes that underwent phacoemulsification combined with endoscopic cyclophotocoagulation (phaco-ECP) with the eyes that underwent phacoemulsification alone. METHODS A retrospective case series review of 103 consecutive eyes that underwent phaco-ECP and 62 eyes that underwent phacoemulsification between January 2006 and August 2012 was conducted. Post-operative refractive outcomes were obtained by subjective refraction or autorefraction. Demographic data, best corrected visual acuity, intraocular pressure, number of glaucoma agents and mean deviation of the Humphrey visual field test (MD) were also analysed. RESULTS The total number of eyes included in the study was 62 eyes for the phaco-ECP group and 62 eyes for the control group who underwent phacoemulsification alone. More than 90% of eyes (n = 56) in phaco-ECP group achieved post-operative refraction within ±1 dioptre (D) of the target refraction. In the control group, 100% of eyes achieved post-operative refraction within ±1D of the target refraction. When comparing the difference between the target and the actual refractive outcome between the phaco-ECP and the control group, there was no statistically significant difference. CONCLUSIONS Refractive outcome after phaco-ECP is comparable to phacoemulsification alone. This study suggests that the intraocular lens power can be selected for cataract surgery alone and that ECP does not change the effective lens position significantly; therefore, no modification of biometry formulae is required. Phaco-ECP should be considered as an effective, safe and predictable surgical treatment option for glaucoma patients with co-existing cataract.

Abstract
Phosphoglycerate mutase 1 (PGAM1) is a glycolytic enzyme that coordinates glycolysis and biosynthesis to promote cancer growth via its metabolic activity. Here, we report the discovery of a non-metabolic function of PGAM1 in promoting cancer metastasis. A proteomic study identified α-smooth muscle actin (ACTA2) as a PGAM1-associated protein. PGAM1 modulated actin filaments assembly, cell motility and cancer cell migration via directly interacting with ACTA2, which was independent of its metabolic activity. The enzymatically inactive H186R mutant retained its association with ACTA2, whereas 201-210 amino acids deleted PGAM1 mutant lost the interaction with ACTA2 regardless of intact metabolic activity. Importantly, PGAM1 knockdown decreased metastatic potential of breast cancer cells in vivo and PGAM1 and ACTA2 were jointly associated with the prognosis of breast cancer patients. Together, this study provided the first evidence revealing a non-metabolic function of PGAM1 in promoting cell migration, and gained new insights into the role of PGAM1 in cancer progression.

Abstract
PMDA-ODA and BPDA-PDA polyimides in 10-50 Atrn thick films were prepared from the respective poly(amic acid) precursor by thermal imidization for 1-10 h at various temperatures over 230-400C. Their water sorption behaviours were studied in detail by gravimetry. Water sorption in both PMDA-ODA and BPDA-PDA followed a nearly Fickian process in spite of the morphological heterogeneity due to the ordered and less ordered phases. Water clustering or plasticization was very weakly evident on the water uptake versus humidity plots. Water sorption in both polyimides was highly dependent upon imidization history. Both diffusion coefficient and water uptake are decreasing functions of imidization temperature and time. This resulted mainly from the enhancement of overall crystallinity by high-temperature imidization because of their high-rT nature. The diffusion coefficient and water uptake were (1.0-3.0) x 10-9 cm2 s-1 and 0.4-4.5 wt% for PMDA-ODA and (0.9-3.0)x 10-cm2s-' and 0. I2-2.40wt%, depending on humidity,/iihidization history and film thickness. The differences between the water sorptions of the p'olyimides are interpreted by considering the differences in their morphologies and chemical affinities to water.

Abstract
Phenotypic differences in drug responses have been associated with known pharmacogenomic loci, but many remain to be characterized. Therefore, we developed next-generation sequencing (NGS) panels to enable broad and unbiased inspection of genes that are involved in pharmacokinetics (PKs) and pharmacodynamics (PDs). These panels feature repetitively optimized probes to capture up to 114 PK/PD-related genes with high coverage (99.6%) and accuracy (99.9%). Sequencing of a Korean cohort (n = 376) with the panels enabled profiling of actionable variants as well as rare variants of unknown functional consequences. Notably, variants that occurred at low frequency were enriched with likely protein-damaging variants and previously unreported variants. Furthermore, in vitro evaluation of four pharmacogenes, including cytochrome P450 2C19 (CYP2C19), confirmed that many of these rare variants have considerable functional impact. The present study suggests that targeted NGS panels are readily applicable platforms to facilitate comprehensive profiling of pharmacogenes, including common but also rare variants that warrant screening for personalized medicine.

Abstract
Recent transcriptomic analysis of the bovine Y chromosome revealed abundant presence of multi-copy protein coding gene families on the male-specific region of the Y chromosome (MSY). Copy number variations (CNVs) of several MSY genes are closely related to semen quality and male reproduction in cattle. However, the CNVs of MSY genes in water buffalo are largely unknown. Therefore, this study aimed to investigate the CNVs of HSFY and ZNF280BY of 298 buffaloes from 17 populations distributed in China, Vietnam and Laos using quantitative PCR. Our results revealed that the median copy numbers of the HSFY and ZNF280BY genes were 47 (ranging from 20 to 145) and 269 (ranging from 73 to 974) respectively. In conclusion, this study indicated that HSFY and ZNF280BY showed abundant CNVs within swamp buffalo populations.

Abstract
Coronaviruses are a diverse group of viruses that infect mammals and birds. Bats are reservoirs for several different coronaviruses in the Alphacoronavirus and Betacoronavirus genera. They also appear to be the natural reservoir for the ancestral viruses that generated the severe acute respiratory syndrome coronavirus and Middle East respiratory syndrome coronavirus outbreaks. Here, we detected coronavirus sequences in next‐generation sequence data created from Eonycteris spelaea faeces and urine. We also screened by PCR urine samples, faecal samples and rectal swabs collected from six species of bats in Singapore between 2011 and 2014, all of which were negative. The phylogenetic analysis indicates this novel strain is most closely related to lineage D Betacoronaviruses detected in a diverse range of bat species. This is the second time that coronaviruses have been detected in cave nectar bats, but the first coronavirus sequence data generated from this species. Bat species from which this group of coronaviruses has been detected are widely distributed across SE Asia, South Asia and Southern China. They overlap geographically, often share roosting sites and have been witnessed to forage on the same plant. The addition of sequence data from this group of viruses will allow us to better understand coronavirus evolution and host specificity.

Molecular imaging allows noninvasive assessment of drug distribution across pharmacological barriers. Thus, it plays an increasingly important role in efforts to understand the interactions of molecules with membrane transporters during drug development and in clinical pharmacology. We describe established and emerging imaging modalities utilized for studying transporter expression and function. We further present examples of how molecular imaging could provide insights into the contribution of transporters to drug disposition and effects.

Abstract
OBJECTIVE To investigate the correlation between contrast-enhanced ultrasound parameters and hepatic venous pressure gradient (HVPG), and to develop a new noninvasive method for the evaluation of portal hypertension in patients with decompensated liver cirrhosis. METHODS One-hundred patients with decompensated liver cirrhosis were examined by contrast-enhanced ultrasound, and the dynamic images were collected for offline analysis. The contrast arrival time was obtained in the hepatic artery (HA), portal vein (PV), and hepatic vein (HV), and HA-HV transit time (HA-HVTT) and PV-HV transit time (PV-HVTT) were calculated. At the same time, HVPG was measured within 24 hours after contrast-enhanced ultrasound, Pearson correlation analysis was performed between each parameter and HVPG, and the receiver operating characteristic (ROC) curve was also used for analysis. RESULTS HV arrival time (HVAT), HA-HVTT, and PV-HVTT were negatively correlated with HVPG (r = -0.385, -0.409, and -0.572, respectively). The area under the ROC curve (AUROC) was 0.903 for PV-HVTT < 2.5 s in judging HVPG≥ l0 mmHg in patients with decompensated liver cirrhosis, and the sensitivity and specificity were 74.4% and 89.5%, respectively. The AUROC was 0.861 for PV-HVTT < 1.5 s in judging HVPG≥l6 mmHg in these patients, and the sensitivity and specificity were 80.4% and 81.5%, respectively. CONCLUSIONS HVAT and intrahepatic transit time demonstrate negative linear correlations with HVPG in patients with decompensated liver cirrhosis, and among all parameters, PV-HVTT shows the strongest correlation with HVPG and can be used to determine and predict the severity of portal hypertension.

Abstract
Objectives: Duodenal–jejunal bypass (DJB) surgery can induce the rapid and durable remission of diabetes. Recent studies indicate that ameliorated hepatic insulin resistance and improved insulin signaling might contribute to the diabetic control observed after DJB. Ras homolog enriched in brain (Rheb) is reported to have an important role in insulin pathway, and some microRNAs (miRNAs) have been found to regulate Rheb. This study was conducted to investigate the effects of DJB on hepatic insulin resistance and the effects of miRNA-200a, a Rheb-targeting miRNA, on the development of DJB-induced amelioration in hepatic insulin resistance. Subjects: We investigated hepatic insulin signaling change and mapped the hepatic miRNAome involved in a rat model of DJB. We studied the effects of miR-200a on Rheb signaling pathway in buffalo rat liver cell lines. Liver tissues were studied and glucose tolerance tests were conducted in DJB rats injected with lentivirus encoding miR-200a inhibitor and diabetic rats injected with miR-200a mimic. Results: Rheb is a potential target of miR-200a. Transfection with an miR-200a inhibitor increased Rheb protein levels and enhanced the feedback action on insulin receptor substrate-dependent insulin signaling, whereas transfection with an miR-200a mimic produced the opposite effects. A luciferase assay confirmed that miR-200a bind to the 3′UTR (untranslated regions) of Rheb. Global downregulation of miR-200a in DJB rats showed impaired insulin sensitivity whereas upregulation of miR-200a in diabetic rats showed amelioration of diabetes. Conclusions: A novel mechanism was identified, in which miR-200a regulates the Rheb-mediated amelioration of insulin resistance in DJB. The findings suggest miR-200a should be further explored as a potential target for the treatment of diabetes.

Abstract
Abstract
Background: Poziotinib is a novel, oral, irreversible pan-HER inhibitor that has shown promising clinical activity in Phase 1 studies of patients (pts) with advance HER2 positive breast cancer who have failed at least 2 prior lines of HER2-directed therapy. A Phase 2 study of poziotinib was initiated in Korea in March 2015 in pts with HER2+ metastatic breast cancer. This phase 2 study is designed to seek accelerated approval for poziotinib for the treatment of metastatic breast cancer in Korea.
Trial Design: Prospective Phase 2, open-label, single-arm, multi-center study in pts with recurrent, Stage IV breast cancer with HER2-overexpression who had received at least 2 prior HER2-directed regimens
Eligibility Criteria: Histologically confirmed breast cancer patients, at least 19 years of age, with confirmed HER2 positive evaluable tumors (per RECIST, 1.1) who have adequate hematologic, renal, and hepatic function and have failed at least two HER2-directed regimens that included a taxane-containing anticancer chemotherapy, with a life expectancy of at least 12 weeks.
Specific Aims: The Primary Efficacy Endpoint of the study was Progression-Free Survival (PFS). The Secondary Efficacy Endpoints included: PFS rate at 12 weeks post-dose; Objective Response Rate (ORR) including Complete Response (CR) and Partial Response (PR) rates; Disease Control Rate (DCR) including CR, PR, and Stable Disease (SD); Duration of Disease Control; Overall Survival (OS); Time to Progression (TTP); Time to Objective Response and Duration of Objective Response. The Exploratory Endpoints included: Population Pharmacokinetic (PK) Profile and Exploratory Genomic and Biomarker Analyses.
Statistical Methods: In the randomized, multicenter, 2-arm, open-label study of trastuzumab emtansine (TH3RESA18), the median PFS was shown to be 3.3 months in subjects with optimal treatment per Investigator's Choice. This ongoing study with poziotinib expects a median PFS of 4.5 months based on data from a previous Phase 1 study of poziotinib (NOV120101). Based on the following assumptions, a 5% one-sided significance level, and 80% power, and 2 months of accrual and 12 months of follow-up, 66 subjects will be required. Accounting for a 10% drop-out rate, a total of 74 subjects will be recruited into this ongoing Phase 2 study.

Abstract
Meloidogyne christiei isolated from turkey oak, Quercus laevies, from the type locality in Florida was characterized using isozyme profiles and ribosomal and mitochondrial gene sequences. The phenotype N1a detected from a single egg-laying female of M. christiei showed one very strong band of malate dehydrogenase (MDH) activity; however, no esterase (EST) activity was identified from macerate of one or even 20 females per well. Phylogenetic relationships within the genus Meloidogyne as inferred from Bayesian analysis of partial 18S ribosomal RNA (rRNA), D2-D3 of 28S rRNA, internal transcribed spacer (ITS) rRNA, and cytochrome oxidase subunit II (COII)-16S rRNA of mitochondrial DNA (mtDNA) gene fragments showed that M. christiei formed a separate lineage within the crown group of Meloidogyne and its relationships with any of three Meloidogyne clades were not resolved.

Abstract
Excessive N-methyl-D-aspartate receptor (NMDAR) activation and the resulting activation of neuronal nitric oxide synthase (nNOS) cause neuronal injury. Homer1b/c facilitates NMDAR-PSD95-nNOS complex interactions, and Homer1a is a negative competitor of Homer1b/c. We report that Homer1a was both upregulated by and protected against NMDA-induced neuronal injury in vitro and in vivo. The neuroprotective activity of Homer1a was associated with NMDA-induced Ca2+ influx, oxidative stress and the resultant downstream signaling activation. Additionally, we found that Homer1a functionally regulated NMDAR channel properties in neurons, but did not regulate recombinant NR1/NR2B receptors in HEK293 cells. Furthermore, we found that Homer1a detached the physical links among NR2B, PSD95 and nNOS and reduced the membrane distribution of NMDAR. NMDA-induced neuronal injury was more severe in Homer1a homozygous knockout mice (KO, Homer1a−/−) when compared with NMDA-induced neuronal injury in wild-type mice (WT, Homer1a+/+). Additionally, Homer1a overexpression in the cortex of Homer1a−/− mice alleviated NMDA-induced neuronal injury. These findings suggest that Homer1a may be a key neuroprotective endogenous molecule that protects against NMDA-induced neuronal injury by disassembling NR2B-PSD95-nNOS complexes and reducing the membrane distribution of NMDARs.

Abstract
BACKGROUND AND AIMS It has been reported that 1,25(OH)2D3 (1,25-VD3) ameliorates the progression of nonalcoholic steatohepatitis (NASH). However, it is unclear whether 1,25-VD3 plays a role in NASH induced by a choline-deficient (CD) diet. In this study, we investigated the roles of 1,25-VD3 in the development and progression of NASH in rats induced by a CD diet. METHODS AND RESULTS Wistar rats with NASH induced by a CD diet were subjected to intraperitoneal injections of 1, 5, or 10 μg/kg of 1,25-VD3 twice weekly for 12 weeks. The administration of 1,25-VD3 decreased free fatty acids (FFAs), triglycerides (TGs), thiobarbituric acid-reactive substances (TBARS), the number of apoptotic cells, and the expression of tissue inhibitor of metalloproteinase-1 (TIMP-1) in the liver, and it improved liver histology, but it did not change the total antioxidant capacity (TAOC) in the liver. Interestingly, the level of CK18-M30 was decreased in the liver of model animals. Treatment with 1,25-VD3 may restrain the downregulation of CK18-M30 in the liver and its release into the bloodstream, thus decreasing the level of serum CK18-M30. 1,25-VD3 supplementation elevated the serum level of 25(OH)D3 and the expression of VDR in the liver. The dose-effect relationship of 1,25-VD3 indicated that 1,25-VD3 slows down the development and progression of NASH induced by a CD diet, but higher doses of 1,25-VD3 may lead to adverse effects. CONCLUSION The results suggest the presence of both antagonistic and adverse dose-dependent effects of the long-term supplementation of 1,25-VD3 on NASH induced by a CD diet.

Abstract
BACKGROUND The tumour-node-metastasis (TNM) classification is the most widely used tool for penile cancer. However, the current system is based on few studies and has been unchanged since 2009. We determined whether a modified pathological N staging system that incorporates the laterality and number of lymph node metastases (LNMs) increases the accuracy of the results in predicting survival compared with the 7th edition of the pathological N staging system of the American Joint Committee on Cancer (AJCC) for penile cancer. METHODS The clinical and histopathologic data from 111 patients with penile cancer with LNMs were analysed. Univariate and multivariate Cox proportional hazard regression analyses were used to determine the impact of the clinical and pathological factors on disease-specific survival of these patients. The predictive accuracy was further assessed using the concordance index. RESULTS According to the 7th edition of the pathological N classification, the 3-year disease-specific survival (DSS) rates for patients with pN1, pN2, and pN3 disease are 89.6%, 65.9%, and 33.6%, respectively (P(N1-N2)=0.030, P(N2-N3)<0.001, P<0.001). Under the modified pathological N category criteria, the 3-year DSS rates for pN1, pN2, and pN3 patients were 90.7%, 60.5%, and 31.4%, respectively (P(N1-N2)=0.005, P(N2-N3)=0.004, P<0.001). In separate multivariate Cox regression models, only modified N stages (hazard ratio: 4.877, 10.895; P=0.018, P<0.001) exhibited independent effects on the outcome. The accuracy of the modified pathological N category was significantly increased. CONCLUSIONS The modified pathological N staging system is a better reflection of the prognosis of patients with penile cancer. Our study should contribute to the improvement of prognostic stratification and systemic treatment to avoid overtreatment of patients.

Abstract
AIMS In order to improve long-term prognosis in schizophrenia, enhancing medication adherence is essential. The aim of this study was thus to identify the association between medication non-adherence and possible risk factors in a large sample of patients with chronic schizophrenia. METHODS One hundred and four patients with schizophrenia with a disease duration of over 10 years were enrolled in this cross-sectional study. The subjects were assessed with the Scale to Assess Unawareness of Mental Disease-Korean version, the Korean version of the Medication Adherence Rating Scale, a neurocognition battery designed for this study, and the Positive and Negative Symptoms Scale. An anova and multiple regression models were conducted to identify the correlations among variables and the factors that contribute to medication adherence. RESULTS The adherence score measured on the Korean version of the Medication Adherence Rating Scale was 7.60 ± 2.12; 88 (84.62%) patients were categorized as well-adherent and 16 (15.38%) as poorly adherent to their medication. Patients with good insight were more likely to maintain their medication (P = 0.0005), and better executive function was associated with increased medication adherence (P = 0.0008). Furthermore, fewer depressive symptoms were associated with good medication adherence (P = 0.0304). CONCLUSIONS This study is the first in the Republic of Korea to identify the relationship between medication adherence, insight, and neurocognition in a large sample of patients with chronic schizophrenia. These results could be used to establish a strategy for improving the prognosis of chronic schizophrenia.
