Abstract
We evaluated the associations between single nucleotide polymorphisms (SNPs) and haplotypes of the genes encoding a disintegrin and metalloproteinase 33 (ADAM33), cluster of differentiation 14 (CD14), and Toll-like receptor 4 (TLR4) and the susceptibility of developing specific adult phenotypes of bronchial asthma in a Chinese Uygur population. Five SNPs of ADAM33 (T1, T2, and V4), 3 SNPs of CD14 (-1359G/T, -1145G/A, and -159T/C), and 2 SNPs of TLR4 (-896A/G and -1196C/T) were genotyped in a Chinese Uygur sample of 126 adult asthmatic patients and 126 control subjects. Gene polymorphisms were detected by polymerase chain reaction-restriction fragment length polymorphism analysis. The genotyping results were confirmed in a random subgroup of our samples using direct DNA sequencing. The allele frequencies of ADAM33 T1 (TC), T2 (AG), and V4 (GG) were significantly higher in patients than in controls (P<0.05). The genotypes T1 (TC+CC), T2 (AG+AA), and V4 (CG+GG) significantly increased the risk of asthma. After adjusting for confounding factors, these associations were stronger and remained significant. The T1 (TC) and V4 (GG) genotypes in the ADAM33 gene were associated with significantly decreased FEV1 levels in patients with asthma. The haplotype frequencies of Hap3 (CAC) and Hap4 (CAG) were significantly higher in patients than in controls (P<0.05). Our results suggest that polymorphisms T1, T2, and V4 in ADAM33 may contribute to the susceptibility to asthma. Specific haplotypes of ADAM33 may contribute to a higher susceptibility to asthma in the Chinese Uygur population.

Abstract
Salmonella infections can become chronic and increase the risk of cancer. The mechanisms by which specific Salmonella organisms contribute to cancer, however, are still unknown. Live and attenuated Salmonella are used as vectors to target cancer cells, but there have been no systematic studies of the oncogenic potential of chronic Salmonella infections in cancer models. AvrA, a pathogenic product of Salmonella, is inserted into host cells during infection and influences eukaryotic cell pathways. In the current study, we colonized mice with Salmonella AvrA-sufficient or AvrA-deficient Salmonella typhimirium strains and induced inflammation-associated colon cancer by azoxymethane/dextran sulfate sodium (AOM/DSS). We confirmed Salmonella persisted in the colon for up to 45 weeks. Salmonella was identified not only in epithelial cells on the colonic luminal surface and base of the crypts but also in invading tumors. Tumor incidence in the AvrA+infected group was 100% compared with 51.4% in the AOM/DSS group without bacterial gavage and 56.3% in mice infected with the AvrA- strain. Infection with AvrA+ strain also altered tumor distribution from the distal to proximal colon that might reflect changes in the microbiome. AvrA-expressing bacteria also upregulated beta-catenin signaling as assessed by decreased beta-catenin ubiquitination, increased nuclear beta-catenin and increased phosphorylated-beta-catenin (Ser552), a marker of proliferating stem-progenitor cells. Other β-catenin targets increased by AvrA included Bmi1, a cancer stem cell marker, matrix metalloproteinase-7, and cyclin D1. In summary, AvrA-expressing Salmonella infection activates β-catenin signals and enhances colonic tumorigenesis. Our findings provide important new mechanistic insights into how a bacterial protein targets proliferating stem-progenitor cells and contributes to cancer development. Our observations also raise a note of caution regarding the use of mutant Salmonella organisms as vectors for anti-cancer therapy. Finally, these studies could suggest biomarkers (such as AvrA level in gut) to assess cancer risk in susceptible individuals and infection-related dysregulation of β-catenin signaling in cancer.

Abstract
BACKGROUND & AIMS Number-needed-to-treat is used in assessing the effectiveness of a health-care intervention, and reports the number of patients who need to be treated to prevent one additional bad outcome. Although largely used in medical literature, there are no studies measuring the benefit of liver transplantation (LT) over hepatic resection (HR) for hepatocellular carcinoma (HCC) in terms of "Number of patients needed to transplant (NTT)." EXCLUSION CRITERIA Child-Turcotte-Pugh (CTP) Classes B-C, very large (>10 cm) and multi-nodular (>2 nodules) tumours, macroscopic vascular invasion and extra-hepatic metastases. STUDY POPULATION 1028 HCC cirrhotic patients from one Eastern (n=441) and two Western (n=587) surgical units. Patient survival observed after HR by proportional hazard regression model was compared to that predicted after LT by the Metroticket calculator. The benefit obtainable from LT compared to resection was analysed in relationship with number of nodules (modelled as ordinal variable: single vs. oligonodular), size of largest nodule (modelled as a continuous variable), presence of microscopic vascular invasion (MVI), and time horizon from surgery (5-year vs. 10-year). RESULTS 330 patients were beyond the Milan criteria (32%) and 597 (58%) had MVI. The prevalence of MVI was 52% in patients within Milan criteria and 71% in those beyond (p<0.0001). In the 5-year transplant benefit analysis, nodule size and HCC number were positive predictors of transplant benefit, while MVI had a strong negative impact on NTT. Transplantation performed as an effective therapy (NTT <5) only in oligonodular HCC with largest diameter >3cm (beyond conventional LT criteria) when MVI was absent. The 10-year scenario increased drastically the transplant benefit in all subgroups of resectable patients, and LT became an effective therapy (NTT <5) for all patients without MVI whenever tumor extension and for oligonodular HCC with MVI within conventional LT criteria. CONCLUSIONS Based on NTT analysis, the adopted time horizon (5-year vs. 10-year scenario) is the main factor influencing the benefit of LT in patients with resectable HCC and Child A cirrhosis.

Abstract
The endoplasmic reticulum type I signal peptidase complex (ER SPC) is a conserved enzyme that cleaves the signal peptides of secretory or membrane preproteins. The deletion of this enzyme leads to the accumulation of uncleaved proteins in biomembranes and cell death. However, the physiological functions of ER SPC in insects are not fully understood. Here, a catalytic subunit gene of ER SPC, LmSPC1, was cloned from Locusta migratoria manilensis and its physiological functions were analysed by RNA interference (RNAi). The LmSPC1 open reading frame encoded a protein of 178 amino acids with all five conserved regions of signal peptidases. RNAi-mediated knockdown of LmSPC1 resulted in high mortality. Sixty-nine per cent of dead nymphs died of abnormal moulting, corresponding to decreased activity of moulting fluid protease. Moreover, insects in the RNAi group experienced a decline in food intake, and a decrease in the secretion of total protein and digestive enzymes from midgut tissues to the midgut lumen. Furthermore, the females produced fewer eggs and eggs with disrupted embryogenesis. These results indicate that LmSPC1 is required for the secretion of secretory proteins, affects physiological functions, including moulting, feeding, reproduction and embryonic development, and is essential for survival. Therefore, LmSPC1 may be a potential target for locust control.

Abstract
DNA methylation plays a significant role in assuring cell identity, thus potentiating its application in molecular classification of cancers in respect to tissue-origins or clinically and etiologically distinct subtypes. In this study, we optimized our liquid hybridization capture-based bisulfite sequencing (LHC-BS) approach on the gene promoter regions of 11 cell lines. Our results indicated that promoter methylomes could not only cluster cancer cell lines with respect to tissue origins but also differentiate cancer subtypes based on CpG island methylator phenotype (CIMP). Promoter-targeted LHC-BS as means for comprehensive screening and classifying cancer cells with promoter methylomes provided a powerful strategy for further complex clinical studies.

Abstract
With data samples collected with the BESIII detector operating at the BEPCII storage ring at center-of-mass energies from 4.009 to 4.420 GeV, the process e+e-→ γX(3872) is observed for the first time with a statistical significance of 6.3σ. The measured mass of the X(3872) is (3871.9 ± 0.7s tat ± 0.2 syst) MeV/c(2), in agreement with previous measurements. Measurements of the product of the cross section σ[e+e- → γX(3872)] and the branching fraction B[X(3872)→π+π-J/ψ] at center-of-mass energies 4.009, 4.229, 4.260, and 4.360 GeV are reported. Our measurements are consistent with expectations for the radiative transition process Y(4260) → γX(3872).

Abstract
AIMS To develop and test a fluorescence in situ hybridization (FISH) based technique and to identify and quantify simultaneously those methanogenic populations colonizing Entodinium spp. in the rumen of cows fed different forages. METHODS AND RESULTS New FISH probes targeting protozoal Entodinium spp. were designed and used together with FISH probes for methanogens in the cow rumen. The composition and relative abundance of methanogenic populations colonizing Entodinium simplex-, E. caudaum- and Entodinium furca-related populations were similar. Methanogens including Methanobrevibacter thaueri, Methanobrevibacter millerae and Methanobrevibacter smithii, and members of Methanomicrobium and Methanosphaera were generally the predominant colonizers of protozoa, regardless of the forage fed to cattle. Individual animals appeared to differ in which ruminal methanogenic populations colonized each of the individual Entodinium spp. CONCLUSIONS Simultaneous FISH probing is shown here to be a reliable and effective approach to investigate the dynamics of symbiotic relationships between ruminal protozoa and methanogens at a single cell level. Phylogenetically closely related Entodinium spp. were colonized by similar methanogenic populations regardless of the forage fed. SIGNIFICANCE AND IMPACT OF THE STUDY This is the first report of the methanogenic archaeal populations that specifically colonize Entodinium spp. as identified using simultaneous FISH probing.

Abstract
OBJECTIVE An outbreak of pulmonary tuberculosis (PTB) occurred in students attending Licai Training School, Gujiao City, China, in early 2011. The epidemic characteristics and possible contributory factors relating to the spread of this outbreak of PTB were studied in a field investigation and are reported here. METHODS Cases were detected by PTB symptom screening, tuberculin skin testing (TST), chest X-radiography, and examination of sputum smears and cultures for all students, school staff and close family contacts of patients with PTB. RESULTS Of the 287 students attending the school, 45 (15.7%) were diagnosed with PTB and two (0.7%) had a positive smear. No PTB was found among staff and close family contacts. Prevalence was high in Science Class 27 and the two floors of the dormitory building where the smear-positive TB patients studied and lived. The frequency of strong TST positivity was also high in Science Class 27 and among close contacts living in the same dormitories as the PTB patients. CONCLUSIONS Several avoidable factors likely to have enhanced disease transmission were identified and several recommendations are made to reduce the risk of future TB outbreaks in schools.

Abstract
BACKGROUND AND PURPOSE To test a hypothesis that: (i) duodenal pH and osmolarity are individually controlled at constant set points by negative feedback control centred in the enteric nervous system (ENS); (ii) the purinergic P2Y(1) receptor subtype is expressed by non-cholinergic secretomotor/vasodilator neurons, which represent the final common excitatory pathway from the ENS to the bicarbonate secretory glands. EXPERIMENTAL APPROACH Ussing chamber and pH-stat methods investigated involvement of the P2Y(1) receptor in neurogenic stimulation of mucosal bicarbonate (HCO(3)(-)) secretion in guinea pig duodenum. KEY RESULTS ATP increased HCO(3)(-) secretion with an EC(50) of 160 nM. MRS2179, a selective P2Y(1) purinergic receptor antagonist, suppressed ATP-evoked HCO(3)(-) secretion by 47% and Cl(-) secretion by 63%. Enteric neuronal blockade by tetrodotoxin or exposure to a selective vasoactive intestinal peptide (VIP, VPAC(1)) receptor antagonist suppressed ATP-evoked HCO(3)(-) secretion by 61 and 41%, respectively, and Cl- by 97 and 70% respectively. Pretreatment with the muscarinic antagonist, scopolamine did not alter ATP-evoked HCO3(-) or Cl(-) secretion. CONCLUSION AND IMPLICATIONS Whereas acid directly stimulates the mucosa to release ATP and stimulate HCO(3)(-) secretion in a cytoprotective manner, neurogenically evoked HCO(3)(-) secretion accounts for feedback control of optimal luminal pH for digestion. ATP stimulates duodenal HCO(3)(-) secretion through an excitatory action at purinergic P2Y(1) receptors on neurons in the submucosal division of the ENS. Stimulation of the VIPergic non-cholinergic secretomotor/vasodilator neurons, which are one of three classes of secretomotor neurons, accounts for most, if not all, of the neurogenic secretory response evoked by ATP.

Abstract
Accurate identification of sparse heterozygous single-nucleotide variants (SNVs) is a critical challenge for identifying the causative mutations in mouse genetic screens, human genetic diseases and cancer. When seeking to identify causal DNA variants that occur at such low rates, they are overwhelmed by false-positive calls that arise from a range of technical and biological sources. We describe a strategy using whole-exome capture, massively parallel DNA sequencing and computational analysis, which identifies with a low false-positive rate the majority of heterozygous and homozygous SNVs arising de novo with a frequency of one nucleotide substitution per megabase in progeny of N-ethyl-N-nitrosourea (ENU)-mutated C57BL/6j mice. We found that by applying a strategy of filtering raw SNV calls against known and platform-specific variants we could call true SNVs with a false-positive rate of 19.4 per cent and an estimated false-negative rate of 21.3 per cent. These error rates are small enough to enable calling a causative mutation from both homozygous and heterozygous candidate mutation lists with little or no further experimental validation. The efficacy of this approach is demonstrated by identifying the causative mutation in the Ptprc gene in a lymphocyte-deficient strain and in 11 other strains with immune disorders or obesity, without the need for meiotic mapping. Exome sequencing of first-generation mutant mice revealed hundreds of unphenotyped protein-changing mutations, 52 per cent of which are predicted to be deleterious, which now become available for breeding and experimental analysis. We show that exome sequencing data alone are sufficient to identify induced mutations. This approach transforms genetic screens in mice, establishes a general strategy for analysing rare DNA variants and opens up a large new source for experimental models of human disease.

Abstract
Outcomes after tendon repair are often unsatisfactory, despite improvements in surgical techniques and rehabilitation methods. Recent studies aimed at enhancing repair have targeted the paucicellular nature of tendon for enhancing repair; however, most approaches for delivering growth factors and cells have not been designed for dense connective tissues such as tendon. Therefore, we developed a scaffold capable of delivering growth factors and cells in a surgically manageable form for tendon repair. Platelet-derived growth factor BB (PDGF-BB), along with adipose-derived mesenchymal stem cells (ASCs), were incorporated into a heparin/fibrin-based delivery system (HBDS). This hydrogel was then layered with an electrospun nanofiber poly(lactic-co-glycolic acid) (PLGA) backbone. The HBDS allowed for the concurrent delivery of PDGF-BB and ASCs in a controlled manner, while the PLGA backbone provided structural integrity for surgical handling and tendon implantation. In vitro studies verified that the cells remained viable, and that sustained growth factor release was achieved. In vivo studies in a large animal tendon model verified that the approach was clinically relevant, and that the cells remained viable in the tendon repair environment. Only a mild immunoresponse was seen at dissection, histologically, and at the mRNA level; fluorescently labeled ASCs and the scaffold were found at the repair site 9days post-operatively; and increased total DNA was observed in ASC-treated tendons. The novel layered scaffold has the potential for improving tendon healing due to its ability to deliver both cells and growth factors simultaneously in a surgically convenient manner.

Abstract
Previous studies have shown that endothelial nitric oxide synthase (eNOS) gene may be involved in abnormal semen parameters. However, the relationship between eNOS G894T polymorphism and semen parameters remains controversial. The purpose of this study was to investigate the association of eNOS G894T polymorphism and semen parameters. The genotype frequency of eNOS G894T was determined in 270 idiopathic asthenozoospermia patients and 248 ethnically matched healthy volunteers using iPLEX genotyping assays on a MassARRAY(®) (Sequenom, San Diego, CA, USA) platform. The statistical analysis performed with Fisher's exact test showed no significant difference in frequencies of genotypes between both groups. The logistic regression showed that genotypes GT, TT and allele T were nonassociated with increased risk of asthenozoospermia in the patient group with ≤5% or >5% sperm with normal forms. The dependence on genotypes of semen parameters was further investigated in both patients and control group. There was no significant difference as compared to control group (P > 0.05). Our study indicated that eNOS gene G894T polymorphism may not have an adverse effect on semen parameters in a Chinese Han population.

Abstract
The phase behavior and the influencing factors of middle phase microemulsions prepared from surfactant-like ionic liquid 1-alkyl-3-methylimidazolium bromide (C12mimBr, C14mimBr and C16mimBr) were studied systematically with Winsor-type phase diagrams. The minimum alcohol content needed to form the middle phase microemulsion, the alcohol width (the range of the alcohol concentrations from forming to disappearing of the middle-phase microemulsion) and the percent volume of the optimal middle phase at the midpoint of the middle phase region were obtained from the phase diagrams. It was found that with the increase in the carbon chain length of CnmimBr molecules, the minimum alcohol content and the alcohol width decrease, and the solubilization ability (the percent volume of the middle phase microemulsion) increases. With the increase in CnmimBr content, the minimum alcohol content increases, and the alcohol width increases at first and then decreases, and the solubilization ability of the microemulsion systems increases. The minimum alcohol content, the alcohol width and the solubilization ability are also influenced by alcohols, oils and brine. The minimum alcohol content and the alcohol width decrease, and the solubilization ability increases, with the increase in the carbon chain length of the alcohols, the decrease in the carbon chain length of the oils, and the increase in NaCl contents.
