Abstract
While Parkinson's disease is the result of dopaminergic dysfunction of the nigrostriatal system, the clinical manifestations of Parkinson's disease are brought about by alterations in multiple neural components, including cortical areas. We examined how 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) administration affected extracellular cortical glutamate levels by comparing glutamate levels in normal and MPTP-lesioned nonhuman primates (Macaca mulatta). Extracellular glutamate levels were measured using glutamate microelectrode biosensors. Unilateral MPTP-administration rendered the animals with hemiparkinsonian symptoms, including dopaminergic deficiencies in the substantia nigra and the premotor and motor cortices, and with statistically significant decreases in basal glutamate levels in the primary motor cortex on the side ipsilateral to the MPTP-lesion. These results suggest that the functional changes of the glutamatergic system, especially in the motor cortex, in models of Parkinson's disease could provide important insights into the mechanisms of this disease.

Abstract
Methotrexate (MTX) is an effective treatment for childhood acute lymphoblastic leukemia (ALL) or Non-Hodgkin lymphoma (NHL); however, toxicity can arise with high doses MTX (HDMTX), especially in patients with delayed MTX elimination. Routine monitoring of plasma MTX concentrations is clinically important, but unfortunately is not always feasible. The aim of this study was to examine the relationship between MTX elimination and renal function to identify parameters that may be useful for predicting delayed MTX elimination in Chinese children with ALL and NHL. A total of 105 children with ALL and NHL were included in the study. Each patient received HDMTX (3 or 5 g/m2) over 24 hours. Plasma MTX concentrations were measured at 24, 48, and 96 hours. Delayed elimination was indicated by plasma MTX concentrations ≥1.0 at 48 hours or ≥0.1 μmol/L at 96 hours. Creatinine clearance rate (CCr) and serum Cr concentrations were measured at 0, 24, and 48 hours. There were 39 patients (37.1%) with delayed MTX elimination. For patients with delayed MTX elimination, the 24 hour plasma MTX concentration was negatively correlated with the 24 hour CCr (P=0.019). The 48 hour plasma MTX concentration was positively correlated with 24 and 48 hour serum Cr concentrations (P=0.001 and P<0.001, respectively), and negatively correlated with the 24 and 48 CCr (both P<0.001). Both MTX concentrations and elimination time decreased with increasing CCr (P<0.05 and P<0.001, respectively). Receiver operating characteristic curves revealed that the best predictors of delayed MTX elimination were 24 hour CCr 36 mmol/L (sensitivity: 64.7%; specificity: 77.4%) (both P < 0.001). CCr and serum Cr concentration may be useful for monitoring plasma MTX concentrations in children receiving HDMTX for ALL and NHL and for predicting delayed MTX elimination.

Abstract
Abstract
Glutamine (Gln) serves as an important source of energy and building blocks for many tumor cells. The first step in Gln utilization is its conversion to glutamate (Glu) by the mitochondrial enzyme glutaminase. CB-839 is a potent, selective, and orally bioavailable inhibitor of both splice variants of glutaminase (KGA and GAC). CB-839 inhibits recombinant GAC with an IC50 of <15 nM. Treatment of the triple-negative breast cancer (TNBC) cell line MDA-MB-231 in vitro with CB-839 reduced cell viability and suppressed cellular Glu pools with comparable potency (IC50 ∼15 nM). TNBC breast cancer cell lines have been reported to have a heightened dependence on exogenous Gln for growth relative to estrogen receptor (ER) positive cells (Kung et al, 2011). Consistent with this observation, an analysis of 58 breast cancer cell lines in the Cancer Cell Line Encyclopedia revealed that low ER and/or Her2 expression is correlated with high glutaminase expression (particularly the GAC isoform) and low expression of glutamine synthetase (GLUL), an enzyme that converts Glu to Gln. This reciprocal pattern of GAC and GLUL expression suggests that TNBC may be particularly sensitive to glutaminase inhibition. To test this hypothesis, the anti-tumor activity of CB-839 was evaluated on a panel of breast tumor cell lines (n>25) that included a mixture of TNBC and ER/Her2-positive subtypes. The TNBC subtype displayed the greatest sensitivity to CB-839 treatment (IC50s ranging from 5-100 nM) and this sensitivity was correlated with: i) dependence on extracellular Gln for growth (r = 0.83, p<0.0001); ii) GAC (but not KGA) expression (r = -0.76, p<0.0001); iii) glutaminase activity in cell lysates (r = -0.75, p = 0.0002); and iv) the ratio of cellular Glu to Gln (r = 0.53, p = 0.014) indicative of efficient Gln to Glu conversion. CB-839 also displayed significant anti-tumor activity in two TNBC xenograft models: 1) as a single agent in a patient-derived tumor chosen based on Gln utilization biomarkers and 2) in a cell line model (JIMT1) both as a single agent and in combination with paclitaxel. To determine if potential markers of Gln utilization and CB-839 sensitivity are reflected in primary tumors, an analysis of large mRNA expression and metabolomic datasets was undertaken. Consistent with the observations in cell lines, there was significantly elevated expression of GAC and reduced expression of GLUL in TNBC tumors relative to the ER+ population in The Cancer Genome Atlas mRNA expression dataset (n = 756). Likewise, analysis of the metabolite levels in 262 primary breast tumors showed that the Glu to Gln ratio in the ER- populations was significantly elevated relative to the ER+ population (fold increase = 3.2, p = 8.0E-09). This elevated metabolite ratio in the ER- population was also significantly correlated with the mRNA expression level of GLUL (r = -0.27, p = 0.001). These observations suggest that biomarkers of Gln utilization and CB-839 sensitivity extend to primary TNBC tumors. Together with the in vitro and in vivo preclinical anti-tumor activity of CB-839 in TNBC models, this primary tumor biomarker evaluation provides a strong rationale for the clinical investigation of CB-839 as a targeted therapeutic in TNBC patients.

Abstract
To understand the pathophysiological mechanisms of pulmonary arterial smooth muscle cell (PASMC) proliferation and extracellular-matrix accumulation in the development of pulmonary hypertension and remodeling, this study determined the effects of different doses of adrenomedullin (ADM) and adrenotensin (ADT) on PASMC proliferation and collagen synthesis. The objective was to investigate whether extracellular signal-regulated kinase (ERK1/2) signaling was involved in ADM- and ADT-stimulated proliferation of PASMCs in 4-week-old male Wistar rats (body weight: 100-150 g, n=10). The proliferation of PASMCs was examined by 5-bromo-2-deoxyuridine incorporation. A cell growth curve was generated by the Cell Counting Kit-8 method. Expression of collagen I, collagen III, and phosphorylated ERK1/2 (p-ERK1/2) was evaluated by immunofluorescence. The effects of different concentrations of ADM and ADT on collagen I, collagen III, and p-ERK1/2 protein expression were determined by immunoblotting. We also investigated the effect of PD98059 inhibition on the expression of p-ERK1/2 protein by immunoblotting. ADM dose-dependently decreased cell proliferation, whereas ADT dose-dependently increased it; and ADM and ADT inhibited each other with respect to their effects on the proliferation of PASMCs. Consistent with these results, the expression of collagen I, collagen III, and p-ERK1/2 in rat PASMCs decreased after exposure to ADM but was upregulated after exposure to ADT. PD98059 significantly inhibited the downregulation by ADM and the upregulation by ADT of p-ERK1/2 expression. We conclude that ADM inhibited, and ADT stimulated, ERK1/2 signaling in rat PASMCs to regulate cell proliferation and collagen expression.

Abstract
Mutations in the Wilms' tumor suppressor gene (WT1) can lead to syndromic forms of steroid-resistant nephrotic syndrome (SRNS) such as Denys-Drash or Frasier syndrome and can cause isolated SRNS. A mutation within WT1 is a frequent cause of sporadic isolated SRNS in girls. In a worldwide cohort of girls, the rate of occurrence was 10.8%. Previous reports have indicated that in Chinese girls, the detection rate of WT1 mutations is 16.7% for early onset isolated nephrotic syndrome. The detection rate of WT1 mutations in Chinese girls with sporadic isolated SRNS is unknown. We examined WT1 mutations in 14 Chinese girls with sporadic isolated SRNS using polymerase chain reaction and direct sequencing and studied a control group of 38 boys with sporadic isolated SRNS. We identified a WT1 mutation in 1 of 14 (7.1% detection rate) Chinese girls with sporadic isolated SRNS. No mutations occurred in WT1 in the remaining 13 girls or the control group. Our investigation supports the necessity of genetic examination for mutations in WT1 in girls with sporadic isolated SRNS.

Abstract
In this study, we hypothesized that the mice immunized with the glycosylphosphatidylinositol (GPI) anchored 6-kDa early-secreted antigenic target (ESAT-6) DNA vaccine (ESAT-6-gpi) and the tumour vaccine B16F10-ESAT-6-gpi/IL-21 might significantly enhance immune responses and antimelanoma efficacy. Our experimental results indicated that the anti-ESAT-6 antibody induced by the DNA vaccine ESAT-6-gpi bound ESAT-6 to the surface of tumour vaccine to activate a complement classical pathway and resulted in the B16F10 tumour cell lysis and apoptosis, which served as a potential trigger for breaking melanomatous immune tolerance to elicit an initiation of natural antimelanoma immunity. Our innovative approach of using the DNA vaccine ESAT-6-gpi priming and the tumour vaccine B16F10-ESAT-6-gpi/IL-21 boosting induced strong antimelanoma immunity that inhibited melanomatous growth. These findings highlighted the DNA vaccine ESAT-6-gpi as an immune enhancer to augment the immune efficacy of the tumour vaccine B16F10-ESAT -6-gpi/IL-21 against melanoma in a mouse model.

Abstract
Telomerase reverse transcriptase (TERT) is reported to protect neurons from apoptosis induced by various stresses including hypoxia-ischemia (HI). However, the mechanisms by which TERT exerts its anti-apoptotic role in neurons with HI injury remain unclear. In this study, we examined the protective role and explored the possible mechanisms of TERT in neurons with HI injury in vitro. Primary cultured neurons were exposed to oxygen and glucose deprivation (OGD) for 3h followed by reperfusion to mimic HI injury in vivo. Plasmids containing TERT antisense, sense nucleotides, or mock were transduced into neurons at 48h before OGD. Expression and distribution of TERT were measured by immunofluorescence labeling and western blot. The expression of cleaved caspase 3 (CC3), Bcl-2 and Bax were detected by western blot. Neuronal apoptosis was measured with terminal deoxynucleotidyl transferase-mediated dUTP nick end-labeling (TUNEL). The mitochondrial reactive oxygen species (ROS) were measured by MitoSOX Red staining. Fluorescent probe JC-1 was used to measure the mitochondrial membrane potential (ΔΨm). We found that TERT expression increased at 8h and peaked at 24h in neurons after OGD. CC3 expression and neuronal apoptosis were induced and peaked at 24h after OGD. TERT inhibition significantly increased CC3 expression and neuronal apoptosis after OGD treatment. Additionally, TERT inhibition decreased the expression ratio of Bcl-2/Bax, and enhanced ROS production and ΔΨm dissipation after OGD. These data suggest that TERT plays a neuroprotective role via anti-apoptosis in neurons after OGD. The underlying mechanisms may be associated with regulating Bcl-2/Bax expression ratio, attenuating ROS generation, and increasing mitochondrial membrane potential.

Abstract
Photorefractive (PR) surface waves (SWs) in self-defocusing LiNbO(3):Fe are studied theoretically and experimentally. We demonstrate that SWs can also be formed in a self-defocusing nonlinear medium and that the nonlocal nonlinearity (such as the diffusion component of PR nonlinearity in this Letter) is the essential cause. The forming process of PR SWs with a self-deflection course of light beams has been observed. The results indicate the possibility of concentrating light energy in self-defocusing media, taking advantage of SWs.

Abstract
The measurement of J/ψ azimuthal anisotropy is presented as a function of transverse momentum for different centralities in Au+Au collisions at sqrt[s(NN)]=200 GeV. The measured J/ψ elliptic flow is consistent with zero within errors for transverse momentum between 2 and 10 GeV/c. Our measurement suggests that J/ψ particles with relatively large transverse momenta are not dominantly produced by coalescence from thermalized charm quarks, when comparing to model calculations.

Abstract
AIMS The purpose of this article is to explore factors influencing adherence to exercise in Chinese people with type 2 diabetes (T2D). The findings can be used to explain exercise behaviours and develop interventions to improve the level of adherence to exercise. METHODS A qualitative approach was used in this study. Data were collected at Nantong City, China. A purposive sampling scheme was used to recruit people with T2D for in-depth semi-structured interviews. Potential patients chosen from the case records in one teaching hospital were screened by telephone for eligibility. Inclusion criteria for recruiting participants were: diagnosis with T2D for at least 6 months; a treatment plan that recommends exercises; and ≥20 years of age. Exclusion criteria included: type 1 diabetes; severe complications of T2D; and cognitive impairment. Each interview was audio-recorded. Recruitment efforts were suspended when the data reached saturation. Thematic analysis was employed to identify themes influencing factors from collected data. RESULTS Seventeen participants were recruited for interviews when data reached saturation. Six themes were identified after thematic analysis: 'beliefs about disease', 'health communication', 'feasibility of regimen', 'conducting skills', 'environmental support' and 'perceived benefits'. CONCLUSION The influencing factors should be comprehensively considered when explaining behaviour relating to exercises or designing health-promotional and health-educational interventions to improve the level of adherence to exercise. This study suggests that health professionals need to pay attention to the patient preferences during health communication to design a feasible exercise regimen in a collaborative way. Non-adherence to exercise cannot be attributed to patients only. Patients should be supported, not blamed. LIMITATION The recruitment of participants from one city might limit the generalizations of the findings to larger areas of China and other ethnic groups. Gender differences related to factors influencing exercises need further consideration.

Abstract
Functional monomer [N-(2,4,4-trimethylpentan-2-yl)acrylamide] was synthesized and characterized by MS and NMR. A series of high molecular weight cationic polyacrylamides were prepared with N-(2,4,4-trimethylpentan-2-yl)acrylamide, acrylamide and methacryloxyethyltrimethyl ammonium chloride by copolymerization using complex initiation systems as catalysts in aqueous solution. Then they used as flocculants to treat the paper-making wastewater. The removal of the colour and the chemical oxygen demand (COD) in the treated waste water samples were determined. Results showed that flocculants could efficiently remove the color and the COD. The overall color and COD removal efficiencies reached as high as 80% and 85%, respectively.

Abstract
Elliptic flow (v(2)) values for identified particles at midrapidity in Au + Au collisions, measured by the STAR experiment in the beam energy scan at RHIC at sqrt[s(NN)] = 7.7-62.4 GeV, are presented. A beam-energy-dependent difference of the values of v(2) between particles and corresponding antiparticles was observed. The difference increases with decreasing beam energy and is larger for baryons compared to mesons. This implies that, at lower energies, particles and antiparticles are not consistent with the universal number-of-constituent-quark scaling of v(2) that was observed at sqrt[s(NN)] = 200 GeV.

Abstract
Breast cancer stem cells (BCSC) exist within many types of breast cancers, functioning to initiate tumorigenesis and augment its progression. The protein profile associated with BCSC has yet to be extensively studied. Mammospheres have been widely employed as a model system to study BCSC. We used proteomics on the MCF-7 breast cancer cell line to compare protein expression in mammosphere-derived cells to that of parental monolayer cells. We identified 34 differentially expressed proteins, seven of which were overexpressed, with the remaining downregulated in mammosphere-derived cells. These differentially expressed proteins include those involved in cell metabolism such as GAPDH and fatty acid synthase, stress response proteins like Hsp27 and FKBP4, and signal transduction related proteins like GIPC1. The expression of breast cancer tumorigenesis and progression-promoting proteins GAPDH and FKBP4 were validated through western blotting. These two proteins are especially recognized for their role in breast cancer resistance to current chemotherapies. The data generated by mammosphere proteomics suggest that this system can identify novel targets for breast cancer stem cells and may provide insights into novel therapy of breast cancer.

Abstract
OBJECTIVES The aim of this study was to explore the technical feasibility of T(1)ρ MRI for the liver, and to determine the normal range of liver T(1)ρ in healthy subjects at clinical 3 T. METHODS There were 15 healthy volunteers. Three representative axial slices were selected to cut through the upper, middle and lower liver. A rotary echo spin-lock pulse was implemented in a two-dimensional fast-field echo sequence. Spin-lock frequency was 500 Hz, and the spin-lock times of 1, 10, 20, 30, 40 and 50 ms were used for T(1)ρ mapping. The images were acquired slice by slice during breath-holding. Regions of interest (ROIs; n=5) were manually placed on each slice of the liver parenchyma region, excluding artefacts and vessels. The mean value of these ROIs (n=15) was regarded as the liver T(1)ρ value for the subject. Six subjects were scanned once at fasting status; six subjects were scanned once 2 h post meal; three subjects were scanned twice at fasting status; and seven subjects were scanned twice 2 h post meal. RESULTS When two readers measured the same 10 data sets, the interreader reproducibility (ICC: intraclass correlation coefficient) was 0.955. With the 10 subjects scanned twice, the ICC for scan-rescan reproducibility was 0.764. There was no significant difference for the liver T(1)ρ value at the fasting status (43.08±1.41 ms) and post-meal status (42.97±2.38 ms, p=0.867). Pooling together all the 32 scans in this study, the normal liver T(1)ρ value ranged from 38.6 to 48.3 ms (mean 43.0 ms, median 42.6 ms). CONCLUSION It is feasible to obtain consistent liver T(1)ρ measurement for human subjects at 3 T.
