Abstract
We aimed to investigate the association between genetic variants of the DNA repair genes XPG, CSB, XPC, CCNH, and MMS19L in the nucleotide excision repair (NER) pathway and risk of prostate cancer in a population in China. This study included 229 patients with newly diagnosed and histopathologically confirmed primary prostate cancer and 238 healthy controls. Genotyping of XPG, CSB, XPC, CCNH, and MMS19L were performed on a 384-well plate on the MassARRAY platform. Associations between the polymorphisms of the six genes and risk of prostate cancer were analyzed using conditional logistical regression. We found that the variant genotype TT of the XPG rs2296147 polymorphism was moderately significantly associated with a higher risk of prostate cancer compared to the wild-type genotype CC [odds ratio (OR)=1.79, 95% confidence interval (CI)=1.01-3.25], and individuals carrying the GG genotype of the CSB rs2228526 polymorphism were associated with an increased risk of prostate cancer (OR=1.95, 95%CI=1.02-3.74). The combination genotype of the XPG T allele and the CSB G allele was associated with a moderately higher risk of prostate cancer risk (OR=1.84, 95%CI=1.06-3.20). In conclusion, we found that polymorphisms in XPG rs2296147 and CSB rs2228526 were significantly associated with prostate cancer susceptibility in the Chinese population analyzed. Our results support the hypothesis that naturally occurring genetic variation of DNA repair genes increases susceptibility to prostate cancer.

Abstract
Sweet potato chlorotic fleck virus (SPCFV) is one of several viruses naturally infecting sweet potato (Ipomoea batatas L.), and it has recently been classified as a new member of the genus Carlavirus (family Flexiviridae) (1). However, SPCFV is distantly related to typical carlaviruses, as most of its putative gene products share amino acid sequence identities of <40% with those of typical carlaviruses (1). China is the largest sweet potato producing country in the world. So far, SPCFV has been reported in eastern China, such as Jiangsu, Anhui, Henan (3), and Guangdong (2) provinces, but no reports exist in western China. Sichuan Province, located in southwestern China, is the largest sweet potato producing area in the country. There are big differences between the environment and climate conditions between Sichuan and eastern China. During 2012, a survey was constructed to determine the genetic diversity and distribution of sweet potato viruses in Sichuan. Forty-seven sweet potato samples exhibiting virus-like symptoms were collected from four different geographic areas of the province. Western blotting using the antisera obtained from the International Potato Center showed that two samples were positive for SPCFV, whereas with reverse transcription (RT)-PCR, only one isolate of SPCFV was obtained from a sample exhibiting symptoms of chlorosis, leaf distortion, and vein clearing. Serological detection indicated that the plant was co-infected with SPCFV, Sweet potato feathery mottle virus (SPFMV), and Sweet potato virus G (SPVG). Total RNA was extracted from symptomatic leaves using Trizol reagent (Invitrogen) according to the manufacturer's protocol, and RT-PCR was performed by using primer pairs SPCFV-CP F (5'-ATGGCGGCGAAGGAGGCTGATA-3') and SPCFV-CP R (5'-TCACTTGCACTTCCCATTAC-3') corresponding to the entire coat protein (CP) gene of SPCFV. Expected DNA fragments of 900 bp were obtained from the symptomatic plant but not from control plants. The obtained fragments were purified and cloned into the PMD19-T vector (TaKaRa). Recombinant plasmids were then transformed into competent cells of Escherichia coli strain DH5α. Nucleotide BLAST analysis revealed that the 900-bp fragment (GenBank Accession No. KC414676) shared 87 to 91% nucleotide identities with other SPCFV isolates available in the GenBank database. To our knowledge, this is the first report of the co-infection between SPCFV and other sweet potato viruses including SPFMV and SPVG in China, and this is the first molecular report of SPCFV in Sichuan, western China. It shows that SPCFV is spreading to a new ecological area of China, and the spread of the virus may affect sweet potato crop yields in western China. Some measures must be carried out quickly to control the virus. References: (1) V. Aritua et al. Arch. Virol. 152:813, 2007. (2) V. Aritua et al. Plant Dis. 93:87, 2009. (3) Q. Wang et al. Crop.

Abstract
Prediction of polypharmacology of known drugs and new molecules against selected multiple targets is highly useful for finding new therapeutic applications of existing drugs (drug repositioning) and for discovering multi-target drugs with improved therapeutic efficacies by collective regulations of primary therapeutic targets, compensatory signalling and drug resistance mechanisms. In this review, we describe recent progresses in exploration of in-silico methods for predicting polypharmacology of known drugs and new molecules by means of structure-based (molecular docking, binding- site structural similarity, receptor-based pharmacophore searching), expression-based (expression profile/signature similarity disease-drug and drug-drug networks), ligand-based (similarity searching, side-effect similarity, QSAR, machine learning), and fragment-based approaches that have shown promising potential in facilitating drug repositioning and the discovery of multi-target drugs.

Abstract
Background: The multidrug resistance and distant metastasis of cholangiocarcinoma result in high postoperative recurrence and low long-term survival rates. It has been demonstrated that the ectopic expression of miR-200 suppresses the multidrug resistance and metastasis of cancer. However, the expression and function of miR-200 in cholangiocarcinoma has not yet been described. Methods: In this study, we identified dysregulated microRNAs (miRNAs, miR) in cholangiocarcinoma tissue by microarray analysis, and subsequent real-time PCR and northern blot analyses validated the expression of candidate miR. We performed functional analyses and investigated the relationship between miR-200b/c expression and the properties of cholangiocarcinoma cells. A dual luciferase assay was applied to examine the effect of miRNAs on the 3′-UTR of target genes, and we demonstrated the function of the target gene by siRNA transfection identifying the downstream pathway via western blotting. Results: We found significantly downregulated expression of four miR-200 family members (miR-200a/b/c/429) and then confirmed that ectopic miR-200b/200c inhibits the migration and invasion of cholangiocarcinoma cells both in vitro and in vivo. We found that miR-200b/c influenced the tumourigenesis of cholangiocarcinoma cells including their tumour-initiating capacity, sphere formation, and drug resistance. We further found that miR-200b/c regulated migration and invasion capacities by directly targeting rho-kinase 2 and regulated tumorigenic properties by directly targeting SUZ12 (a subunit of a polycomb repressor complex). Conclusion: Our study shows that miR-200b/c has a critical role in the regulation of the tumorigenic and metastatic capacity of cholangiocarcinoma and reveals the probable underlying mechanisms.

Abstract
To reduce the toxic effect on normal cells and improve the treatment effects of docetaxel, a novel transferrin modified docetaxel-loaded long circulating liposome for ovarian tumor was established for the first time. The transferrin-modified long-circulating liposomes loaded with docetaxel (TF-LP-DOC) were prepared by the post-insertion method and exhibited excellent characteristics in terms of particle size, encapsulation efficiency and stability. We investigated the targeting efficiencies of liposomes by the cellular uptake in vitro and biodistribution in vivo, and identified the therapeutic effects using cytotoxicity experiment (in vitro)and tumor growth inhibition (in vivo) on ovarian cancer. The in vitro and in vivo results showed that TF-LP-DOC were successfully established and presented an enhanced targeting ability. With decreased side effect and improved anti-tumor efficacy of chemotherapeutic drugs, TF-LP-DOC proved itself to be a very promising tumor targeted drug delivery system.

Abstract
We report on broadband absorption spectroscopy in the near IR using a multipass cell design based on highly reflecting mirrors in a confocal arrangement having the particular aim of achieving long optical paths. We demonstrate a path length of 314 m in a cell consisting of two sets of highly reflecting mirrors with identical focal length, spaced 0.5 m apart. The multipass cell covers this path length in a relatively small volume of 1.25 l with the light beam sampling the whole volume. In a first application, the absorption spectra of the greenhouse gases CO(2), CH(4), and CO were measured. In these measurements we used a femtosecond fiber laser with a broadband spectral range spanning the near IR from 1.5 to 1.7 μm. The absorption spectra show a high signal-to-noise ratio, from which we derive a sensitivity limit of 6 ppmv for methane observed in a mixture with air.

Abstract
Cheilinus undulatus (humphead wrasse) is a marine fish distributed widely throughout the tropical Indo-Pacific. It has been listed as vulnerable in the IUCN Red Data Book and in CITES Appendix II four times. Fifteen microsatellite loci were isolated and characterized for this species. The number of alleles ranged from 3 to 15 per locus, and the observed and expected heterozygosity ranged between 0.0323-0.7742 and 0.2597-0.8773, respectively. The polymorphism information content ranged from 0.2353-0.8520. Four microsatellite loci deviated significantly from Hardy-Weinberg expectations. No significant linkage disequilibrium was found among any of the loci. These microsatellite loci will be useful for future investigations of genetic variation in the wrasse population.

Abstract
Abstract
A 45 mm diameter single-screw “transparent” extruder was employed for an investigation on the dynamic performance of screws of different configurations. The extruder had eight glass windows installed along the entire metal barrel which enabled visual observation to be easily made. It was demonstrated, with this extruder, that pressure profile appeared to be an important factor for screw performance such as throughput rate, residence time, mixing characteristics, break-up of solid-bed, etc. The full-flight screw had the lowest pressure profile among all the screws tested, and its performance was found to be generally inferior to that of the mixing screws. The Darnell and Mol solid plug flow theory was shown to be applicable only to the mixing screws for the solid flow behaviour in the entire solid conveying section. The secondary flight of the barrier screw was found to effectively suppress solid bed break-up, but only at low screw speed. A screw with a Maddock mixing device was found to have the highest throughput rate. Other findings were believed to be of practical significance in the screw design.

Abstract
Abstract
The previous study on the dynamic processing characteristics of co-rotating twin-screw extruder based on a visible technique (which employed a “transparent” extruder) performed by the authors Wong et al. [1 and 2] had enabled a quantitative treatment to be carried out in the present paper on the melting behaviour of polymer during an extrusion process. The qualitative analysis performed previously [1] had led to the development of a melting model which was capable of revealing some of the fundamental melting behaviour. The model also enabled the determination of the length of screw required for completing melting (Zr). Melting characteristics in terms of effects of solid feeding rate, temperature, screw speed and channel depth on the predicted Zr were discussed to further our understanding on melting performance of polymer melt in intermeshing corotating twin-screw extruder.

Abstract
Numerous studies have shown that human endogenous retrovirus W family (HERV-W) envelope gene (env) is related to various diseases but the underlying mechanism has remained poorly understood. Our previous study showed that there was abnormal expression of HERV-W env in sera of patients with schizophrenia. In this paper, we reported that overexpression of the HERV-W env elevated the levels of small conductance Ca(2+)-activated K(+) channel protein 3 (SK3) in human neuroblastoma cells. Using a luciferase reporter system and RNA interference method, we found that functional cAMP response element site was required for the expression of SK3 triggered by HERV-W env. In addition, it was also found that the SK3 channel was activated by HERV-W env. Further study indicated that cAMP response element-binding protein (CREB) was required for the activation of the SK3 channel. Thus, a novel signaling mechanism of how HERV-W env influences neuronal activity and contributes to mental illnesses such as schizophrenia was proposed.

Abstract
OBJECTIVE To provide radiographic parameters for optimal placement of posterior second sacral alar iliac (S2AI) screw for instrumentation and fusion of scoliosis to the second sacral level in a Chinese population. METHODS S2AI screw trajectories were mapped on three-dimensional computed tomography (3DCT) reconstructions of 60 normal adult pelvises. 1 mm inferior and 1 mm lateral to the S1 dorsal foramen were chosen as the entry point, and ideal S2AI screw trajectories were explored by rotating and cutting the 3D pelvis, ensuring that the trajectories were of maximum length and width. The directions and depth of these determined trajectories were then measured. RESULTS The ideal S2AI screw trajectories could be found in each pelvis. The left and right screw trajectory parameters for males were shown as follows: angulation was L 29.15 ± 8.60° vs. R 29.96 ± 8.28° (p = 0.286) caudally in the sagittal plane and L 36.49 ± 3.14° vs. R 37.16 ± 3.14° (p = 0.165) laterally in the transverse plane. The maximal and intrasacral lengths of trajectory were L 121.25 ± 8.33 vs. R 120.63 ± 7.54 mm (p = 0.460) and L 26.20 ± 3.31 vs. R 26.92 ± 4.76 mm (p = 0.268). The entry point was L 28.87 ± 3.33 vs. R 29.79 ± 3.55 mm (p = 0.186) lateral to the second sacral midline, and L 44.14 ± 11.87 vs. R 43.89 ± 12.53 mm (p = 0.687) underneath the skin. The trajectories for females were more caudal (L: 34.50 ± 6.56° vs. 29.15 ± 8.60°, p = 0.009; R: 35.72 ± 7.53° vs. 29.96 ± 8.28°, p = 0.007) in the sagittal plane, but the lateral angulation in the transverse plane showed no difference between genders (p > 0.05). The female iliac medullar cavities were obviously narrower than those of males (L: 14.76 ± 2.46 vs. 16.98 ± 3.52, p = 0.006; R: 14.94 ± 2.60 vs. 17.00 ± 2.81, p = 0.005). Although the average maximal length of trajectories for females were about 5 mm shorter than those of males, intrasacral length were equal to those of males. Furthermore, both the distance from entry point to the S2 midline and skin in the transverse plane showed no difference between genders. CONCLUSION The feasibility to insert S2AI screws to the sacrum and ilium in an Asian population along with the ideal entry angle and length of trajectory were identified for clinical practice.

Abstract
Background: Fatigue and pelvic organ dysfunction are common among women with multiple sclerosis (MS), which may prolong labor and increase the risk of labor induction and/or augmentation. Objective: We set out to investigate the association between MS and related clinical factors (disease duration and the Expanded Disability Status Scale, EDSS) with labor induction/augmentation. Methods: Data from the British Columbia (BC) MS database were linked with the BC Perinatal Database Registry. Multivariable models were used to compare the likelihood of labor induction and augmentation between attempted vaginal deliveries (1998–2009) in women with MS ( n=381) and the general population ( n=2615). Results: In the MS cohort, 94/381 deliveries (25%) required labor induction and 147/381 deliveries (39%) required labor augmentation. Having MS was not associated with labor induction (adjusted odds ratio (OR)=0.91; 95% confidence interval (CI)=0.68–1.22, p=0.54) or augmentation (adjusted OR=0.91; 95% CI=0.72–1.15, p=0.43), but was associated with multiple methods of labor induction (OR=1.94; 95% CI=1.23–3.06, p=0.004). A higher EDSS score was associated with an increased risk of labor induction (adjusted p=0.04), but not labor augmentation (adjusted p > 0.5). Disease duration was not associated with either outcome (adjusted p > 0.2). Conclusions: Greater intervention may be required to initiate labor for women with a higher degree of disability due to MS.

Abstract
RNF2, also known as Ring1B/Ring2, is a component of the polycomb repression complex 1 (PRC1). RNF2 is highly expressed in many tumors, suggesting that it might have an oncogenic function, but the mechanism is unknown. Here we show that knockdown of RNF2 significantly inhibits both cell proliferation and colony formation in soft agar, and induces apoptosis in cancer cells. Knockdown of RNF2 in HCT116 p53+/+ cells resulted in significantly more apoptosis than was observed in RNF2 knockdown HCT116 p53−/− cells, indicating that RNF2 knockdown-induced apoptosis is partially dependent on p53. Various p53-targeted genes were increased in RNF2 knockdown cells. Further studies revealed that in RNF2 knockdown cells, the p53 protein level was increased, the half-life of p53 was prolonged and p53 ubiquitination was decreased. In contrast, cells overexpressing RNF2 showed a decreased p53 protein level, a shorter p53 half-life and increased p53 ubiquitination. Importantly, we found that RNF2 directly binds with both p53 and MDM2 and promotes MDM2-mediated p53 ubiquitination. RNF2 overexpression could also increase the half-life of MDM2 and inhibit its ubiquitination. The regulation on p53 and MDM2 stability by RNF2 was also observed during the etoposide-induced DNA damage response. These results provide a possible mechanism explaining the oncogenic function of RNF2, and because RNF2 is important for cancer cell survival and proliferation, it might be an ideal target for cancer therapy or prevention.
