Abstract
In this study, we examined the integrity of Foot-and-mouth disease virus (FMDV) particles during their binding to the surface of BHK-21 cells under physiological condition. For monitoring of the virus integrity we used blocking of the endocytosis with dynasore and cytochalasin D followed by RT-PCR for viral protein VP1 and the resistance of FMDV to the treatment of RNase A. Our results showed that integrin binding to VP1 did not cause a substantial conformational change in the viral capsid. Furthermore, treatment with RNase A showed no effect on the infectivity of intact as well as cell-bound virions. Our findings confirmed that FMDV entered the host cells in the form of intact virions.

Abstract
We report the first measurement of charged particle elliptic flow in Pb-Pb collisions at sqrt[S(NN)] =2.76 TeV with the ALICE detector at the CERN Large Hadron Collider. The measurement is performed in the central pseudorapidity region (|η|<0.8) and transverse momentum range 0.2<p t<5.0 GeV/c. The elliptic flow signal v₂, measured using the 4-particle correlation method, averaged over transverse momentum and pseudorapidity is 0.087 ± 0.002(stat) ± 0.003(syst) in the 40%-50% centrality class. The differential elliptic flow v₂ p t reaches a maximum of 0.2 near p t =3 GeV/c. Compared to RHIC Au-Au collisions at sqrt[S(NN)] 200 GeV, the elliptic flow increases by about 30%. Some hydrodynamic model predictions which include viscous corrections are in agreement with the observed increase.

Abstract
The first measurement of the charged-particle multiplicity density at midrapidity in Pb-Pb collisions at a center-of-mass energy per nucleon pair √ S NN = 2.76 TeV is presented. For an event sample corresponding to the most central 5% of the hadronic cross section, the pseudorapidity density of primary charged particles at midrapidity is 1584 ± 4(stat) ± 76(syst), which corresponds to 8.3 ± 0.4(syst) per participating nucleon pair. This represents an increase of about a factor 1.9 relative to pp collisions at similar collision energies, and about a factor 2.2 to central Au-Au collisions at √ S NN = 2.76 TeV. This measurement provides the first experimental constraint for models of nucleus-nucleus collisions at LHC energies.

Abstract
The ratio of the yields of antiprotons to protons in pp collisions has been measured by the ALICE experiment at sqrt[s]=0.9 and 7 TeV during the initial running periods of the Large Hadron Collider. The measurement covers the transverse momentum interval 0.45<p_{t}<1.05 GeV/c and rapidity |y|<0.5. The ratio is measured to be R_{|y|<0.5}=0.957±0.006(stat)±0.014(syst) at 0.9 TeV and R_{|y|<0.5}=0.991±0.005(stat)±0.014(syst) at 7 TeV and it is independent of both rapidity and transverse momentum. The results are consistent with the conventional model of baryon-number transport and set stringent limits on any additional contributions to baryon-number transfer over very large rapidity intervals in pp collisions.

Abstract
Epigenetic silencing of secreted frizzled-related protein (SFRP) genes, antagonists of the WNT pathway, contributes to the pathogenesis of several cancers including non-small cell lung cancer (NSCLC). We hypothesize that methylation analysis of SFRPs family could improve their use as a panel of biomarkers for diagnosing and staging of NSCLC in China. The expression of four SFRP members (SFRP1, 2, 4, and 5) in NSCLC samples was screened by RT-PCR and quantitative real-time PCR. Only SFRP1 was significantly downregulated in NSCLC, as compared to adjacent normal tissues and benign pulmonary disease tissues (P=0.006). Promoter hypermethylation of SFRP1 was found in 32.1% (25/78) NSCLC specimens and was closely correlated with loss of expression, besides SFRP1 hypermethylation was associated with lymph metastasis (P=0.039) and disease progression within one year (P=0.027). Furthermore, methylated SFRP1 was detected in 28.2% (22/78) of plasma samples from NSCLC patients while only 4% (2/50) in cancer-free controls, and the concordance of SFRP1 methylation status in tumor tissues and corresponding plasmas was satisfactory (P <0.001). In conclusion, epigenetic inactivation of SFRP1 is a common event contributing to lung carcinogenesis and maybe used as a potential biomarker for NSCLC in Chinese population.

Abstract
This paper presents an investigation on the fluorescent properties of semiconductor CdTe quantum dots (QDs) self-assembled on the surface of PVP (polyvinylpyrrolidone)-capped silver nanoparticles (NPs) by the ligand field effect. A significant 2.5-fold enhancement in the integrated fluorescence intensities, red shift of fluorescence peak, and obvious decrease of lifetime were observed in the CdTe QDs assembled on the Ag NPs in comparison with the pure CdTe QDs. The fluorescence enhancement factor and red shift were found to depend on the Ag NP concentration. The fluorescence enhancement was attributed to a highly localized electromagnetic field on the Ag NPs generated by the surface plasma and the change in the surface trap state of the CdTe QDs originating from plasma oscillations in the Ag NPs. It is first proposed that the surface passivation of CdTe QDs is also an important factor for metal-enhanced fluorescence. The surface defects of CdTe QDs can be modified by the Cd-O coordination interaction between the CdTe QDs and PVP molecules, which will cause the trap state density and luminescence lifetime to decrease. The surface passivation of CdTe QDs can also improve fluorescence quantum yield and lead to the red shift of the fluorescence peak. Compared with previous reports, the occurrence of the self-assembly of CdTe QDs on the surface of PVP-capped Ag NPs is fairly simple and easy. From a practical point of view, the combination of CdTe QDs with Ag NPs may lead to the fluorescence enhancement, which could be utilized in a variety of chemical and biological detection applications.

Abstract
We examine the magnetoresistance (MR) of conducting polymers with interest paid on the role of structural flexibility. Through Monte Carlo simulation and Green function method, we evaluate the electric transmission for a variety of polymer configurations. It is found that for a single polymer the transmission displays a complex oscillation and also a parity-dependent periodicity. For an ensemble of polymers the averaged transmission yields the nonlinear behavior of MR under varying magnetic fields. Interestingly, more flexible polymers are shown to achieve higher MR, depending on the population and the size of the loops.

Abstract
OBJECTIVE To investigate the CAG trinucleotide repeat expansion in spinocerebellar ataxia (SCA) types 1, 2, 3, 6, 7, 12, and 17 from Chinese Han. METHODS The pathological CAG triplet repeat expansions of the SCA1, SCA2, SCA3/Machado-Joseph disease (MJD), SCA6, SCA7, SCA12 and SCA17 genes were analyzed in a cohort of 559 Mainland Chinese patients affected by spinocerebellar ataxia, including 363 probands from families with autosomal dominant SCA and 196 sporadic cases. Polymerase chain reaction, agarose gel electrophoresis, recombinant DNA technology by T-vector cloning and direct sequencing were performed to detect the CAG-repeat number of abnormal allele. RESULTS Among the 559 SCA patients, twenty-three were positive for SCA1, the ranges of expanded CAG repeats were from 39 to 60 (mean:51.09+/-4.88); thirty-two were positive for SCA2, the ranges of expanded CAG repeats were from 36 to 51 (mean:40.34+/-4.40); three hundred and five were positive for SCA3/MJD, the ranges of expanded CAG repeats were from 49 to 86 (mean:73.84+/-5.07); nine were positive for SCA6, the ranges of expanded CAG repeats were from 23 to 29 (mean:25.56+/-1.94); twenty-seven were positive for SCA7, the ranges of expanded CAG repeats were from 38 to 71(mean:58.22+/-10.90); three were positive for SCA12, the ranges of expanded CAG repeats were from 51 to 52 (mean:51.33+/-0.58); and finally, two were positive for SCA17, the range of expanded CAG repeats were from 53 to 55 (mean:54.00+/-1.41). CONCLUSION The 39 CAG repeats of SCA1, 49 CAG repeats of SCA3 and 51 CAG repeats of SCA12 are all the shortest known causative expanded alleles, while the 86 CAG repeats of SCA3/MJD is the largest full expanded allele that has never been reported. Furthermore, it is the first report of SCA17 subtype in Mainland Chinese and first research that established the abnormal reference standard of CAG repeat number of different subtypes of SCA in Chinese Han.

Abstract
e19541 Background: Positron emission tomography (PET)/computed tomography (CT) scan has a well-established role in the management of non-Hodgkin's lymphoma (NHL). However, in case of the primary gastric lymphoma, which is the most frequent extranodal NHL, the role of PET/CT scan is still controversial. Methods: We retrospectively analyzed 42 patients with primary gastric lymphoma who underwent PET/CT scans; 32 patients with diffuse large B-cell lymphoma (DLBCL) and 10 patients with extranodal marginal zone B-cell lymphoma of mucosa-associated lymphoid tissue (MALT lymphoma) were analyzed. The PET/CT scans were compared with clinicopathologic features and the results of CT and endoscopy. After corresponding treatment, response was evaluated by conventional CT scans or PET/CT scans and endoscopy with biopsy Results: Nine patients were up-staged based on the results of their PET/CT scan compared to CT (7 DLBCL, 2 MALT lymphomas) while six patients were down-staged by the PET/CT scan. The high SUVmax group, defined as SUVmax ≥ median value, was significantly associated with an advanced Lugano stage (P < 0.001). Three patients with DLBCL, who showed an initially high SUVmax, died of disease progression. Although not statistically significant, there was a tendency of inferior outcome in the group with high SUVmax. Among 24 patients for whom follow-up PET/CT scan with endoscopy was performed, 11 patients with ulcerative or mucosal lesions showed residual FDG uptake. All of these gastric lesions were grossly and pathologically benign lesions without evidence of lymphoma cells. Conclusions: PET/CT scan can help staging patients with primary gastric lymphoma, and the maximum SUV has possibility to have prognostic value. However, the residual FDG uptake observed during follow-up should be interpreted cautiously in association with the results of endoscopy and multiple gastric biopsies. No significant financial relationships to disclose.

Abstract
2056 Background: Patients with glioblastoma multiforme (GBM) suffer from neurocognitive decline due to both the disease and its treatment. We analyzed neurocognitive function of patients with recurrent GBM who participated in the BRAIN study, a phase II, multicenter, randomized, noncomparative clinical trial which assessed the efficacy and safety of bevacizumab alone or in combination with irinotecan. Methods: Eighty-five patients who participated in the bevacizumab-only group of the BRAIN study were assessed with the Hopkins Verbal Learning Test-Revised (HVLT-R), Trail Making Test parts A (TMTA) and B (TMTB), and the Controlled Oral Word Association (COWA) test. Assessments were conducted at baseline and then every 6 weeks while patients remained on study drug, up to 52 weeks. Change in neurocognitive function from baseline to Week 6 was categorized as improved, stable, or declined, using the reliable change index. Changes were confirmed at the next assessment, when available. Results were not adjusted for practice effects. Results: Between 93 and 98% of patients completed each test at baseline and 73–78% completed each test at both baseline and Week 6. The majority of patients demonstrated stable performance on each test at Week 6, relative to baseline. With the exception of the COWA test, 18–25% of patients demonstrated improved performance on one or more tests at Week 6. Conclusions: Preliminary results suggest that the majority of patients with recurrent GBM who were treated with bevacizumab alone in the BRAIN study demonstrated stable or improved neurocognitive function during the first 6 weeks of treatment. Changes across tasks and associations with measures of clinical efficacy, patient characteristics, and concomitant medications will be explored. [Table: see text] [Table: see text]

Abstract
Vestibular compensation refers to the behavioral recovery after a unilateral peripheral vestibular lesion. In chickens, posture and balance deficits are present immediately following unilateral vestibular ganglionectomy (UVG). After three days, most operated chickens begin to recover, but severe deficits persist in others. The tangential nucleus is a major avian vestibular nucleus whose principal cells are vestibular reflex projection neurons. From patch-clamp recordings on brain slices, the percentage of spontaneous spike firing principal cells, spike discharge rate, ionic conductances, and spontaneous excitatory postsynaptic currents (sEPSCs) were investigated one and three days after UVG. Already by one day after UVG, sEPSC frequency increased significantly on the lesion side, although no differences were detected in the percentage of spontaneous spike firing cells or discharge rate. In compensated chickens three days after UVG, the percentage of spontaneous spike firing cells increased on the lesion side and the discharge rate increased bilaterally. In uncompensated chickens three days after UVG, principal cells on the lesion side showed increased discharge rate and increased sEPSC frequency, whereas principal cells on the intact side were silent. Typically, silent principal cells exhibited smaller persistent sodium conductances and higher activation thresholds for the fast sodium channel than spiking cells. In addition, silent principal cells on the intact side of uncompensated chickens had larger dendrotoxin-sensitive potassium conductance, with a higher ratio of Kv1.1 surface/cytoplasmic expression. Increased sEPSC frequency in principal cells on the lesion side of uncompensated chickens was accompanied by decreased Kv1.2 immunolabeling of presynaptic terminals on principal cell bodies. Thus, both intrinsic ionic conductances and excitatory synaptic inputs play crucial roles at early stages after lesions. Unlike the principal cells in compensated chickens which showed similar percentages of spontaneous spike firing cells, discharge rates, and sEPSC frequencies bilaterally, principal cells in uncompensated chickens displayed gross asymmetry in these properties bilaterally.

Abstract
OBJECTIVE To study the single-nucleotide substitution (c.-16C to T) of the PURATROPHIN-1 gene in spinocerebellar ataxia (SCA) patients in China. METHODS The single-nucleotide substitution (c.-16C to T) of the PURATROPHIN-1 gene was detected by PCR, digested with EcoN I, separated on 8% polyacrylamide gel in 68 probands of autosomal dominant SCA families and 119 sporadic SCA patients, who had been excluded CAG/CAA repeat expansion at the SCA1, 2, 3, 6, 7, 17 and dentatorubral-pallidolluysian atrophy (DRPLA) loci. The results were confirmed in four patients by direct sequencing. RESULTS The single-nucleotide substitution (c.-16C to T) of the PURATROPHIN-1 gene was not identified in authors' cohort. CONCLUSION The mutation of c.-16C to T of the PURATROPHIN-1 gene might be rare in SCA patients in China.

Abstract
Abstract
Much work has been carried out on adsorption capacity of coals. Diffusive transport processes within the coal matrix blocks could be the rate-limiting step for adsorption during gas injection and production operations. Identifying these processes and determining their contributions to overall mass transport is a complex and time consuming procedure. The paper presents numerical diffusion models in varying coal particles and investigates transport mechanisms. For this purpose, the coal particle is represented as a microporous solid penetrated by a network of larger interconnected macropores. The solid adsorbs the bulk of the gas. A simple relationship between the apparent and intrinsic Fickian diffusion coefficients is derived in the case of single-component (methane) transport and Langmuir-type adsorption. Mass transport in the bidisperse coal particle is significantly influenced by the adsorption in the microporous solid. The investigation is then extended to study concentration dependence of the microporous solid diffusion for binary (methane-CO2) mixtures using the Maxwell-Stefan formulation. It is found that co-diffusion of the gas molecules enhances the gas mass transport in the solid in the presence of competitive sorption dynamics, while counter-diffusion may diminish the gas mass transport. The influence of lateral interactions among the adsorbed molecules in the solid phase is discussed. The work finds application in modelling CBM and CO2-ECBM processes.
Introduction
As an unconventional natural gas resource, coalbed methane receives worldwide attention. Deep coal seams that are not accessible for mining are suitable for in situ gas production using conventional drilling, well completion and gas recovery technologies. Hence, a vast amount of natural gas is globally available. Unlike conventional gas resources, however, the gas storage, flow and transport processes in coalbeds are quite complex mainly due to the intricate nature of coal(1–6).
Coalbeds are porous media often characterized by a bimodal pore structure: a primary structure consisting of micro- and meso-scale pores, and a secondary structure with macropores and interconnected natural fractures. The microporous coal has an extremely large internal surface area and a strong affinity for certain naturally occurring chemical species such as methane, carbon dioxide, nitrogen and water. At high coalbed pressures, therefore the majority of the natural gas-in-place, in particular, methane, exists abundantly at an adsorbed liquid-like state in the microporous solid(1).
Depressurizing the coalbed may yield a significant volume of natural gas. However, the initial stage of recovery is often dominated by water production, whereas, the latter stage is under the influence of diffusional resistances of the primary pores of the coal matrix. Treatment and disposal of the produced water is expensive and its long-term environmental impact has not been clearly understood yet. Injection of a second gas with much higher adsorption capacity, on the other hand, could possibly enhance recovery by maintaining the overall reservoir pressure, thus, keeping the water production at a minimum level. Additionally, injecting a second gas would promote methane desorption by lowering the partial pressure of the coalbed methane in the migrating gas phase.

Abstract
OBJECTIVE Brain abnormalities in neuromyelitis optica (NMO) attracted much attention. Our study was to identify the brain magnetic resonance imaging (MRI) abnormalities in Chinese NMO patients. METHODS Patients who fulfilled the latest diagnostic criteria of NMO proposed by Wingerchuk et al. [Neurology 66 (2006) 1485] and whose brain MRI did not meet the multiple sclerosis (MS) criteria of McDonald et al. [Ann Neurol 50 (2001) 121] were selected to perform MRI scanning of the brain, spinal cord and optic nerves. RESULTS Twenty-eight of 33 patients (84.8%) had abnormal MRI findings. Twenty-two patients (66.7%) presented with well-defined brain parenchymal lesions and the other six patients (18.2%) with macroscopic symmetrical diffuse hyperintensities in deep white matter. Fifteen of 22 patients had more than one lesion (> or =2 lesions) and the other seven patients had single lesion. In the supratentorium, most lesions were punctate or small round dot and non-specific in juxtacortical, subcortical and deep white matter regions, a few were patchy atypical confluent lesions. Brainstem was easily involved (14/33, 42.4%) especially in medulla (7/33, 21.2%). CONCLUSIONS This study demonstrates the characteristics of brain MRI abnormalities in Chinese NMO patients, which are helpful to the revision of diagnostic criteria for NMO.

Abstract
A new multichannel HCN interferometer has been developed on HL-2A tokamak, which is characterized by two techniques: (1) the wave-guide HCN laser with cavity length of 6 m to increase the optical resource power and (2) high response room temperature waveguide Schottky diode detectors to obtain good beat signal. The space resolution is 7 cm by the use of focusing metal mirrors mounted on the vacuum chamber and a compensated optical system. In the 2006 experiment campaign, this new interferometer has been applied for plasma density profile and density sawtooth measurement.
