Abstract
Nasopharyngeal carcinoma (NPC) is a malignant epithelial tumor with tremendous invasion and metastasis capacities, and it has a high incidence in southeast Asia and southern China. Previous studies identified that far upstream element-binding protein 1 (FBP1), a transcriptional regulator of c-Myc that is one of the most frequently aberrantly expressed oncogenes in various human cancers, including NPC, is an important biomarker for many cancers. Our study aimed to investigate the expression and function of FBP1 in human NPC. Quantitative real-time RT-PCR (qRT-PCR), western blot and immunohistochemical staining (IHC) were performed in NPC cells and biopsies. Furthermore, the effect of FBP1 knockdown on cell proliferation, colony formation, side population tests and tumorigenesis in nude mice were measured by MTT, clonogenicity analysis, flow cytometry and a xenograft model, respectively. The results showed that the mRNA and protein levels of FBP1, which are positively correlated with c-Myc expression, were substantially higher in NPC than that in nasopharyngeal epithelial cells. IHC revealed that the patients with high FBP1 expression had a significantly poorer prognosis compared with the patients with low expression (P=0.020). In univariate analysis, high FBP1 and c-Myc expression predicted poorer overall survival (OS) and poorer progression-free survival. Multivariate analysis indicated that high FBP1 and c-Myc expression were independent prognostic markers. Knockdown of FBP1 reduced cell proliferation, clonogenicity and the ratio of side populations, as well as tumorigenesis in nude mice. These data indicate that FBP1 expression, which is closely correlated with c-Myc expression, is an independent prognostic factor and promotes NPC progression. Our results suggest that FBP1 can not only serve as a useful prognostic biomarker for NPC but also as a potential therapeutic target for NPC patients.

Abstract
BACKGROUND Glutathione-S-transferase P1 (GSTP1) methylation has been demonstrated to be associated with oxidative stress induced liver damage in acute-on-chronic hepatitis B liver failure (ACHBLF). AIM To evaluate the methylation level of GSTP1 promoter in acute-on-chronic hepatitis B liver failure and determine its predictive value for prognosis. METHODS One hundred and five patients with acute-on-chronic hepatitis B liver failure, 86 with chronic hepatitis B (CHB) and 30 healthy controls (HC) were retrospectively enrolled. GSTP1 methylation level in peripheral mononuclear cells (PBMC) was detected by MethyLight. Clinical and laboratory parameters were obtained. RESULTS GSTP1 methylation levels were significantly higher in patients with acute-on-chronic hepatitis B liver failure (median 16.84%, interquartile range 1.83-59.05%) than those with CHB (median 1.25%, interquartile range 0.48-2.47%; P < 0.01) and HC (median 0.80%, interquartile range 0.67-1.27%; P < 0.01). In acute-on-chronic hepatitis B liver failure group, nonsurvivors showed significantly higher GSTP1 methylation levels (P < 0.05) than survivors. GSTP1 methylation level was significantly correlated with total bilirubin (r = 0.29, P < 0.01), prothrombin time activity (r = -0.24, P = 0.01) and model for end-stage liver disease (MELD) score (r = 0.26, P = 0.01). When used to predict 1- or 2-month mortality of acute-on-chronic hepatitis B liver failure, GSTP1 methylation showed significantly better predictive value than MELD score [area under the receiver operating characteristic curve (AUC) 0.89 vs. 0.72, P < 0.01; AUC 0.83 vs. 0.70, P < 0.05 respectively]. Meanwhile, patients with GSTP1 methylation levels above the cut-off points showed significantly poorer survival than those below (P < 0.05). CONCLUSIONS Aberrant GSTP1 promoter methylation exists in acute-on-chronic hepatitis B liver failure and shows high predictive value for short-term mortality. It might serve as a potential prognostic marker for acute-on-chronic hepatitis B liver failure.

Abstract
Withaferin A (WFA) is an active compound from Withania somnifera and has been reported to exhibit a variety of pharmacological activities such as anti—inflammatory, immunomodulatory and anti—tumor properties. In the present study, we investigated the potential protective role of WFA on acute lung injury in neonatal rats induced by lipopolysaccharide (LPS). We found that WFA significantly attenuated the pathological changes of lungs induced by LPS injection. Administration with WFA obviously decreased pulmonary neutrophil infiltration accompanied with decreased MPO concentrations. WFA also reduced the expression of pro—inflammatory cytokines including MIP—2, TNF—α, IL—1β and IL—6. Meanwhile, the expression levels of anti—inflammatory mediators such as TGF—β1 and IL—10 were significantly increased following WFA administration. Moreover, WFA protected LPS—treated rats from oxidative damage via up—regulation of TBARS and H2O2 concentrations and down—regulation of ROS contents. Taken together, the present study demonstrated that WFA administration attenuated LPS—induced lung injury through inhibition of inflammatory responses and oxidative stress.

Abstract
Hepatitis B virus is classically considered a hepatotropic virus but also infects peripheral blood mononuclear cells. Chronic hepatitis B has different disease phases modulated by host immunity. We compared HBV variability, drug resistance and immune escape mutations in the overlapping HBV polymerase/surface gene in plasma and peripheral blood mononuclear cells in different disease phases. Plasma and peripheral blood mononuclear cells were isolated from 22 treatment naïve patient cohorts (five inactive, six immune-active, nine HBeAg negative and two immune-tolerant). HBV was genotyped via line probe assay, hepatitis B surface antigen titres were determined by an in-house immunoassay, and HBV DNA was quantified by kinetic PCR. The HBV polymerase/surface region, including full genome in some, was PCR-amplified and cloned, and ~20 clones/sample were sequenced. The sequences were subjected to various mutational and phylogenetic analyses. Clonal sequencing showed that only three of 22 patients had identical HBV genotype profiles in both sites. In immune-active chronic hepatitis B, viral diversity in plasma was higher compared with peripheral blood mononuclear cells. Mutations at residues, in a minority of clones, associated with drug resistance, and/or immune escape were found in both compartments but were more common in plasma. Immune escape mutations were more often observed in the peripheral blood mononuclear cells of immune-active CHB carriers, compared with other disease phases. During all CHB disease phases, differences exist between HBV variants found in peripheral blood mononuclear cells and plasma. Moreover, these data indicate that HBV evolution occurs in a compartment and disease phase-specific fashion.

Abstract
Cathepsin K (CTSK) is an important protease responsible for degrading type I collagen, osteopontin, and other bone matrix proteins. The mutations in the CTSK gene can cause pycnodysostosis (OMIM 265800), a rare autosomal recessive bone dysplasia. Patients with pycnodysostosis have been reported to present specific dental abnormalities; however, whether these dental abnormalities are related to dysfunctional CTSK has never been reported. Here we investigated the histologic changes of cementum and alveolar bone in a pycnodysostosis patient, caused by novel compound heterozygous mutations in the CTSK gene (c.87 G>A p.W29X and c.848 A>G p.Y283C). The most impressive manifestations in tooth were extensive periradicular high-density clumps with unclear periodontal space by orthopantomography examination and micro-computed tomography scanning analysis. Hematoxylin/eosin and toluidine blue staining and atomic force microscopy analysis showed that the cementum became significantly thickened, softened, and full of cementocytes. The disorganized bone structure was the main character of alveolar bone. The p.W29X mutation may represent the loss-of-function allele with an earlier termination codon in the precursor CTSK polypeptide. Residue Y283 is highly conserved among papain-like cysteine proteases. Three-dimensional structure modeling analysis found that the loss of the hydroxybenzene residue in the Y283C mutation would interrupt the hydrogen network and possibly affect the self-cleavage of the CTSK enzyme. Furthermore, p.Y283C mutation did not affect the mRNA and protein levels of overexpressed CTSK in COS-7 system but did reduce CTSK enzyme activity. In conclusion, the histologic and ultrastructural changes of cementum and alveolar bone might be affected by CTSK mutation via reduction of its enzyme activity (clinical trial registration: ChiCTR-TNC-10000876).

Abstract
The G-protein-coupled bile acid receptor Gpbar1 (TGR5) has been demonstrated to be able to negatively regulate hepatic inflammatory response. In this study, we aimed to determine the methylation status of TGR5 promoter in patients with acute-on-chronic hepatitis B liver failure (ACHBLF) and its predictive value for prognosis. We enrolled 76 consecutive ACHBLF patients, 80 chronic hepatitis B (CHB) patients and 30 healthy controls (HCs). Methylation status of TGR5 promoter in peripheral mononuclear cell (PBMC) was detected by methylation-specific polymerase chain reaction (MSP). The mRNA level of TGR5 was determined by quantitative real-time polymerase chain reaction (RT-qPCR). We found that the frequency of TGR5 promoter methylation was significantly higher in ACHBLF (35/76, 46.05%) than CHB patients (5/80, 6.25%; χ(2) = 32.38, P < 0.01) and HCs (1/30, 3.33%; χ(2) = 17.50, P < 0.01). TGR5 mRNA level was significantly lower (Z = -9.12, P < 0.01) in participants with aberrant methylation than those without. TGR5 methylation showed a sensitivity of 46.05% (35/76), specificity of 93.75% (75/80), positive predictive value (PPV) of 87.5% (35/40) and negative predictive value (NPV) of 64.66% (75/116) in discriminating ACHBLF from CHB patients. ACHBLF patients with methylated TGR5 showed significantly poor survival than those without (P < 0.01). When used to predict 3-month mortality of ACHBLF, TGR5 methylation [area under the receiver operating characteristic curve (AUC) = 0.75] performed significantly better than model for end-stage liver diseases (MELD) score (AUC = 0.65; P < 0.05). Therefore, our study demonstrated that aberrant TGR5 promoter methylation occurred in ACHBLF and might be a potential prognostic marker for the disease.

Abstract
OBJECTIVES Celastrol, a quinone methide triterpenoid, could induce apoptosis in pancreatic cancer cells. The purpose of this study is to determine whether there is protective autophagy after celastrol treatment in pancreatic cancer cells and the synergistic effects of celastrol and 3-MA in vitro and in vivo. METHODS The cells viability was measured using MTT assays. Degree of apoptosis and amount of autophagic vacuoles were measured by flow cytometry. Immunofluorescence was adapted to monitor the localization of autophagic protein LC3-II. Expression of LC3-II, cleaved caspase-3, Bax and bcl-2 was detected by immunoblot. Autophagosomes were observed by electron microscopy. The synergistic effect of celastrol and 3- MA in vivo was studied in the MiaPaCa-2 xenograft tumor model. RESULTS Celastrol increased the level of autophagy in pancreatic cancer cells. Furthermore in vitro, when inhibiting the autophagy with 3-MA, the level of celastrol-induced apoptosis elevated; after upgrading autophagy by starvation, the level of celastrol-induced apoptosis descended. 3-MA enhanced celastrol-induced apoptosis and inhibitory effect on tumor growth in vivo. CONCLUSIONS In pancreatic cancer, celastrol treatment increased the level of autophagy to protect cancer cells against apoptosis. Autophagy inhibitor 3-MA could improve the therapeutic effect of celastrol in vitro and in vivo.

Abstract
The aim of this study was to evaluate the effects of antibacterial peptide (ABP) sufficiency on cellular immune functions by determining the spleen cell cycle and apoptosis, peripheral blood T cell subsets, and T cell proliferation function in weaned piglets. A total of 90 piglets (Duroc × Landrace × Yorkshire) of both sexes were randomly allotted to 5 dietary treatments. Each treatment consisted of 3 replicates with 6 piglets per replicate. The dietary treatments consisted of the negative control (NC; basal diet), positive control (PC; basal diet supplemented with 400 mg/kg Astragalus polysaccharide), and ABP (basal diet mixed with 250, 500, and 1,000 mg/kg ABP). The experimental lasted for 28 d. Two piglets from each replicate were selected randomly for blood samples extraction from the jugular vein to obtain peripheral blood T cell subsets, and T cell proliferation function analysis was performed on d 32, 39, 46, and 53. Two piglets from each replicate were selected and euthanized to observe the spleen cell cycle and apoptosis on d 39 and 53. In ABP-sufficient piglets, the G0/G1 phase of the spleen cell cycle was much lower (P < 0.05) and the S and G2 + M phases and proliferation index (PI) were greater (P < 0.05) than in NC piglets. The percentage of apoptotic cells in the spleen significantly decreased under ABP sufficiency (P < 0.05). The proliferation function of peripheral blood T cells increased (P < 0.05) in ABP-sufficient piglets. Percentages of CD3 (+) and CD3 (+)CD4 (+) ratios (d 39, 46, and 53) and CD4 (+)CD8 (+) ratios (d 32, 39, 46, and 53) increased remarkably (P < 0.05) under ABP sufficiency compared with NC. These results suggest that ABP sufficiency could increase the T cell population and proliferation function of T cells and could induce decreased percentages of apoptotic cells. Overall, the cellular immune function was evidently improved in weaned piglets. We suggest optimal dosages of 500 mg/kg ABP for 4-wk addition and 1,000 mg/kg ABP for 2-wk addition.

Abstract
BACKGROUND Despite substantial research, uncertainty remains about the clinical and etiological heterogeneity of major depression (MD). Can meaningful and valid subtypes be identified and would they be stable cross-culturally? METHOD Symptoms at their lifetime worst depressive episode were assessed at structured psychiatric interview in 6008 women of Han Chinese descent, age ⩾ 30 years, with recurrent DSM-IV MD. Latent class analysis (LCA) was performed in Mplus. RESULTS; Using the nine DSM-IV MD symptomatic A criteria, the 14 disaggregated DSM-IV criteria and all independently assessed depressive symptoms (n = 27), the best LCA model identified respectively three, four and six classes. A severe and non-suicidal class was seen in all solutions, as was a mild/moderate subtype. An atypical class emerged once bidirectional neurovegetative symptoms were included. The non-suicidal class demonstrated low levels of worthlessness/guilt and hopelessness. Patterns of co-morbidity, family history, personality, environmental precipitants, recurrence and body mass index (BMI) differed meaningfully across subtypes, with the atypical class standing out as particularly distinct. CONCLUSIONS MD is a clinically complex syndrome with several detectable subtypes with distinct clinical and demographic correlates. Three subtypes were most consistently identified in our analyses: severe, atypical and non-suicidal. Severe and atypical MD have been identified in multiple prior studies in samples of European ethnicity. Our non-suicidal subtype, with low levels of guilt and hopelessness, may represent a pathoplastic variant reflecting Chinese cultural influences.

Abstract
BACKGROUND Experimental and clinical studies have suggested that the presence of fragmented QRS complex (fQRS) is associated with various cardiovascular diseases. fQRS may predict major adverse cardiovascular events (MACE). The current meta-analysis was performed using clinical outcome studies to evaluate the role of fQRS in coronary artery disease (CAD). METHODS A systematic search of electronic databases (Cochrane, Medline, Embase and Pubmed) from their inception to April 2014 was performed. Data were extracted from applicable articles to evaluate the prognostic value of fQRS in CAD. RESULTS A total of 16 observational studies about fQRS and CAD (n = 3,997 patients) were identified. Compared with the non-fQRS group, MACE and mortality were significantly higher in the fQRS group -odds ratios (OR) 3.19, 95 % confidence interval (95 % CI) [2.3, 4.42], p < 0.00001; OR 2.24, 95 % CI [1.71, 2.94], p < 0.0001. Patients developed Q waves, anterior-wall myocardial infarction (MI), and low left ventricular ejection fraction (LVEF) more frequently in the fQRS group than in the non-fQRS group-OR 2.59, 95 % CI [1.76, 3.81], p < 0.00001; OR 2.43, 95 % CI [1.07, 5.52], p = 0.03; OR - 6.43, 95 % CI [- 9.11, - 3.74], p < 0.00001. CONCLUSION Based on current evidence, fQRS was associated with increased MACE, mortality, Q waves, anterior-wall MI, and decreased LVEF in CAD. These findings show that fQRS is a reliable marker in CAD.

Abstract
OBJECTIVE Antithyroid drug therapy is one of the main medical treatments for Graves' disease. There have been conflicting reports as to whether the addition of exogenous L-thyroxine improves remission rates more than antithyroid drugs alone. This randomized, controlled and prospective clinical trial was undertaken to investigate the long-term outcome of methimazole treatment with or without exogenous L-thyroxine in Chinese patients. METHODS 145 patients with Graves' disease were randomly divided into 3 groups and all patients initially received 30 mg of methimazole daily for at least 1 month and then followed the titration -regimen with or without L-thyroxine: group 1 (30 mg→20 mg→15 mg→10 mg→5 mg); group 2 (30 mg→20 mg→15 mg→10 mg+L-thyroxine→5 mg+L-thyroxine); group 3 (30 mg→20 mg→15 mg→10 mg+L-thyroxine→5 mg+L-thyroxine→2.5 mg+L-thyroxine). The drug therapy was discontinued after 5 months of the final dose. RESULTS 16 out of 46 patients in group 1 (34.8%), 12 out of 47 in group 2 (25.5%) and 16 out of 52 in group 3 (30.8%) had a recurrence of Graves' disease within 6-year follow-up after drug withdrawal. Survival Analysis showed no significant differences in the remission rates between any 2 groups, despite the remission rates in group 2 and 3 were slightly higher than that in group 1. CONCLUSIONS The addition of L-thyroxine to methimazole treatment in patients with Graves' disease neither improves nor prevents the remission or recurrence of Graves' disease in China.

Abstract
The relationship between property and structure is one of the most important fundamental questions in the field of nanomaterials and nanodevices. Understanding the multiproperties of a given nano-object also aids in the development of novel nanomaterials and nanodevices. In this paper, we develop for the first time a comprehensive platform for in situ multiproperty measurements of individual nanomaterials using a scanning electron microscope (SEM). Mechanical, electrical, electromechanical, optical, and photoelectronic properties of individual nanomaterials, with lengths that range from less than 200 nm to 20 μm, can be measured in situ with an SEM on the platform under precisely controlled single-axial strain and environment. An individual single-walled carbon nanotube (SWCNT) was measured on the platform. Three-terminal electronic measurements in a field effect transistor structure showed that the SWCNT was semiconducting and agreed with the structure characterization by transmission electron microscopy after the in situ measurements. Importantly, we observed a bandgap increase of this SWCNT with increasing axial strain, and for the first time, the experimental results quantitatively agree with theoretical predictions calculated using the chirality of the SWCNT. The vibration performance of the SWCNT, a double-walled CNT, and a triple-walled CNT were also studied as a function of axial strain, and were proved to be in good agreement with classical beam theory, although the CNTs only have one, two, or three atomic layers, respectively. Our platform has wide applications in correlating multiproperties of the same individual nanostructures with their atomic structures.

Abstract
An optical fiber sensor based on long-period gratings (LPG) for selective measurements of flap- and edge-wise bending of a wind turbine blade is presented. Two consecutive LPGs separated by 40 mm interfere to improve resolution and reduce noise in a D-shaped fiber. The mode profile of the device was characterized experimentally to provide a model describing the mode couplings. The sensor was tested on a wind turbine blade.

Abstract
Estrogen receptor-alpha positive (ER+) breast cancers comprise the majority of human breast cancers, but molecular mechanisms underlying this subtype of breast cancers remain poorly understood. Here, we show that ER+ mammary luminal tumors arising in Tip30−/−MMTV-Neu mice exhibited increased enrichment of luminal progenitor gene signature. Deletion of the Tip30 gene increased proportion of mammary stem and progenitor cell populations, and raised susceptibility to ER+ mammary luminal tumors in female Balb/c mice. Moreover, Tip30−/− luminal progenitors displayed increases in propensity to differentiate to mature ER+ luminal cells and FoxA1 expression. Knockdown of FoxA1 expression in Tip30−/− progenitors by shRNA specific for FoxA1 reduced their differentiation toward ER+ mature luminal cells. Taken together, our results suggest that TIP30 is a key regulator for maintaining ER+ and ER−luminal pools in the mammary luminal lineage, and loss of it promotes expansion of ER+ luminal progenitors and mature cells and ER+ mammary tumorigenesis.

Abstract
BACKGROUND The symptoms of major depression (MD) are clinically diverse. Do they form coherent factors that might clarify the underlying nature of this important psychiatric syndrome? METHOD Symptoms at lifetime worst depressive episode were assessed at structured psychiatric interview in 6008 women of Han Chinese descent, age ⩾30 years with recurrent DSM-IV MD. Exploratory factor analysis (EFA) and confirmatoryfactor analysis (CFA) were performed in Mplus in random split-half samples. RESULTS The preliminary EFA results were consistently supported by the findings from CFA. Analyses of the nine DSM-IV MD symptomatic A criteria revealed two factors loading on: (i) general depressive symptoms; and (ii) guilt/suicidal ideation. Examining 14 disaggregated DSM-IV criteria revealed three factors reflecting: (i) weight/appetite disturbance; (ii) general depressive symptoms; and (iii) sleep disturbance. Using all symptoms (n = 27), we identified five factors that reflected: (i) weight/appetite symptoms; (ii) general retarded depressive symptoms; (iii) atypical vegetative symptoms; (iv) suicidality/hopelessness; and (v) symptoms of agitation and anxiety. CONCLUSIONS MD is a clinically complex syndrome with several underlying correlated symptom dimensions. In addition to a general depressive symptom factor, a complete picture must include factors reflecting typical/atypical vegetative symptoms, cognitive symptoms (hopelessness/suicidal ideation), and an agitated symptom factor characterized by anxiety, guilt, helplessness and irritability. Prior cross-cultural studies, factor analyses of MD in Western populations and empirical findings in this sample showing risk factor profiles similar to those seen in Western populations suggest that our results are likely to be broadly representative of the human depressive syndrome.

Abstract
1. This study was conducted to determine the effects of different dietary fat sources on growth performance, tibia fatty acids and biomarkers of bone metabolism in broilers. 2. One-d-old commercial Arbor Acres broilers were fed with a maize-soya bean basal diet for 42 d, supplemented with oils according to the following 5 treatments: lard (lard group); linseed oil (linseed oil group); palm oil (palm oil group); linseed oil + palm oil (60:40 or 40:60 w/w, LP-1 group and LP-2 group, respectively). 3. No significant differences in weight gain, feed intake and gain/feed ratio were observed between the lard and linseed oil groups. Birds fed on palm oil had significantly greater weight gain and feed intake than those fed on lard or linseed oil. Growth performance in LP-1 and LP-2 was significantly greater than that of single-oil groups. 4. Tibia growth and bone characteristics were not influenced by supplementation with lard, linseed oil, or palm oil alone, but broilers fed on a mixture of fats had significantly greater tibia weight and length compared to broilers fed on linseed oil. Bone mineral density in tibia was significantly increased in LP-1 and LP-2 groups. 5. Supplementation of linseed oil alone or in combination with palm oil enhanced apparent digestibility of calcium, reduced serum calcium and increased tibia calcium concentrations. Moreover, supplementation with linseed oil alone or in combination with palm oil had a positive effect on biomarkers of bone growth. 6. The combination of linseed and palm oils was beneficial for growth performance, tibia growth and biomarkers of bone metabolism.

Abstract
Exportin 4 (XPO4) is a novel identified candidate tumour-suppressor gene involved in the pathogenesis of hepatocellular carcinoma (HCC). This study was aimed to determine the clinical features of XPO4 mRNA expression and promoter methylation status in peripheral blood mononuclear cells (PBMCs) of patients with chronic hepatitis B virus (HBV) infection. PBMCs were isolated from 44 HCC, 38 liver cirrhosis (LC), 34 chronic hepatitis B (CHB) patients and 17 healthy controls (HCs). The mRNA level and promoter methylation status of XPO4 were determined by quantitative real-time RT-PCR and methylation-specific PCR, respectively. XPO4 mRNA level of HCC patients was significantly lower compared with LC and CHB patients as well as HCs (all P < 0.01, respectively), and significant differences of the XPO4 mRNA level were found in LC and CHB group than in HCs (LC vs HCs, P < 0.01; CHB vs HCs, P < 0.05). Methylation rate of XPO4 promoter was significantly increased in patients with HCC than in patients with CHB and HCs (both P < 0.05). DNA methylation pattern was responsible for the suppression of XPO4 transcription in the progression of HBV infection (P = 0.000). Furthermore, AFP level was significantly higher in HCC patients with XPO4 methylation than in those without methylation ((8702 ± 15635) μm vs (1052 ± 5370) μm, P < 0.05). In conclusion, transcription of XPO4 gene was gradually decreased and methylation rate of XPO4 promoter was increased with the progression of HBV infection. Methylation status of XPO4 in PBMCs tended to be a noninvasive biomarker to predict HCC and the progression of HBV infection.

Abstract
Aging refers to the physical and functional decline of the tissues over time that often leads to age-related degenerative diseases. Accumulating evidence implicates that the senescence of neural stem cells (NSCs) is of paramount importance to the aging of central neural system (CNS). However, exploration of the underlying molecular mechanisms has been hindered by the lack of proper aging models to allow the mechanistic examination within a reasonable time window. In the present study, we have utilized a hydroxyurea (HU) treatment protocol and effectively induced postnatal subventricle NSCs to undergo cellular senescence as determined by augmented senescence-associated-β-galactosidase (SA-β-gal) staining, decreased proliferation and differentiation capacity, increased G0/G1 cell cycle arrest, elevated reactive oxygen species (ROS) level and diminished apoptosis. These phenotypic changes were accompanied by a significant increase in p16, p21 and p53 expression, as well as a decreased expression of key proteins in various DNA repair pathways such as xrcc2, xrcc3 and ku70. Further proteomic analysis suggests that multiple pathways are involved in the HU-induced NSC senescence, including genes related to DNA damage and repair, mitochondrial dysfunction and the increase of ROS level. Intriguingly, compensatory mechanisms may have also been initiated to interfere with apoptotic signaling pathways and to minimize the cell death by downregulating Bcl2-associated X protein (BAX) expression. Taken together, we have successfully established a cellular model that will be of broad utilities to the molecular exploration of NSC senescence and aging.

Abstract
We report a new design of carbon nanotube (CNT) resonator, whose resonance frequency can be tuned not only transversally by a gate voltage, but also by the axial strain applied through directly pulling the CNT. The resonators are fabricated from individual suspended single-walled CNT (SWCNT) in situ inside a scanning electron microscope. The resonance frequency of a SWCNT resonator can be tuned by more than 20 times with an increase of quality factor when the axial strain of the SWCNT is only increased from nearly zero to 2% at room temperature. The transversal gate-tuning ability is found to be weaker than the axial-tuning ability and decrease with increasing the axial strain. The gate voltage can hardly tune the resonance frequency when the initial axial strain is larger than 0.35% and the CNT acts like a tied string. The relationship among resonance frequency, gate voltage, and initial axial strain of the CNT obtained presently will allow for the designs of CNT resonators with high frequency and large tuning range. The present resonator also shows ultrahigh sensitivity in displacement and force detection, with a resolution being better than 2.4 pm and 0.55 pN, respectively.

Abstract
BACKGROUND AND PURPOSE Recent studies found that microembolic signals (MESs) could be detected by transcranial Doppler in patients with moyamoya disease. However, the clinical significance of MESs in moyamoya disease remains unclear. Our aim was to investigate whether the MESs could predict cerebral ischaemic events in patients with moyamoya disease. METHODS Fifty-four consecutive patients with moyamoya disease were recruited. MESs were monitored by transcranial Doppler for 30 min in the bilateral middle cerebral arteries of each patient on admission. Patients were followed up for 1 year. The primary end-point was cerebral ischaemic events including stroke and transient ischaemic attack (TIA). RESULTS MESs were detected in 11 (20.4%) patients, with a frequency of 11 (10.2%) in 108 hemispheres. Logistic regression analysis revealed that previous ischaemic events within 3 months were associated with the presence of MESs (odds ratio 4.41, 95% CI 1.11-17.59). During a median follow-up of 384 days, 14 (13.0%) hemispheres had ischaemic events (seven strokes and seven TIAs). Cox regression showed that the hazard ratio for the risk of new ischaemic stroke and TIA in the hemispheres with MESs was 6.84 (95% CI 1.82-25.66) compared with those without, and 10.61 (95% CI 1.66-67.70) for ischaemic stroke alone, after controlling for age, sex, presence of ischaemic events at baseline, Suzuki stages and revascularization surgery. CONCLUSIONS In patients with moyamoya disease, the presence of MESs is associated with recent ischaemic symptoms and independently predicts cerebral ischaemic events. MES detection may be of potential clinical value in the management of patients with moyamoya disease.

PTEN regulates AMPA receptor-mediated cell viability in iPS-derived motor neurons. Cell Death Dis 2014; 5:e1096.

Abstract
Excitatory transmission in the brain is commonly mediated by the α-amino-3-hydroxy-5-methyl-4-isoxazole propionic acid (AMPA) receptors. In amyotrophic lateral sclerosis (ALS), AMPA receptors allow cytotoxic levels of calcium into neurons, contributing to motor neuron injury. We have previously shown that oculomotor neurons resistant to the disease process in ALS show reduced AMPA-mediated inward calcium currents compared with vulnerable spinal motor neurons. We have also shown that PTEN (phosphatase and tensin homolog deleted on chromosome 10) knockdown via siRNA promotes motor neuron survival in models of spinal muscular atrophy (SMA) and ALS. It has been reported that inhibition of PTEN attenuates the death of hippocampal neurons post injury by decreasing the effective translocation of the GluR2 subunit into the membrane. In addition, leptin can regulate AMPA receptor trafficking via PTEN inhibition. Thus, we speculate that manipulation of AMPA receptors by PTEN may represent a potential therapeutic strategy for neuroprotective intervention in ALS and other neurodegenerative disorders. To this end, the first step is to establish a fibroblast-iPS-motor neuron in vitro cell model to study AMPA receptor manipulation. Here we report that iPS-derived motor neurons from human fibroblasts express AMPA receptors. PTEN depletion decreases AMPA receptor expression and AMPA-mediated whole-cell currents, resulting in inhibition of AMPA-induced neuronal death in primary cultured and iPS-derived motor neurons. Taken together, our results imply that PTEN depletion may protect motor neurons by inhibition of excitatory transmission that represents a therapeutic strategy of potential benefit for the amelioration of excitotoxicity in ALS and other neurodegenerative disorders.

Abstract
PURPOSE To create a patient respiratory management system and patient self-practice tool using the Wii remote, a widely available consumer hardware product. METHODS The Wii remote (Wiimote) (Nintendo, Redmond, WA) contains an infrared (IR) camera that can track up to four spots whose coordinates are reported to a host computer via Bluetooth. The Wiimote is capable of tracking a fiducial box currently used by a commercial monitoring system [Real-time Position Management(TM) (RPM) system, Varian Associates, Palo Alto, CA], if the correct IR source is used. The authors validated the Wiimote tracking by comparing the amplitude and frequency of signals among those reported by Wiimote with known movements from an inhouse servo-driven respiratory simulator, as well as with those measured using the RPM. The simulator comparison was done using standard sinusoid signals with amplitude of 2.0 cm as well as recorded patient respiratory traces. The RPM comparisons were done by simultaneously recording the RPM reflective box position with the Wiimote and the RPM. Timing was compared between these two systems by using the digital beam-on signal from the CT scanner, for the 4DCT to synchronize these acquisitions. RESULTS The data acquisition rate from the Wiimote was 100.0 ± 0.4 Hz with a version 2.1 Bluetooth adaptor. The standard deviation of the height of the motion extrema was 0.06 and 1.1 mm when comparing those measured by the Wiimote and the servomotor encoder for standard sinusoid signal and prerecorded patient respiratory signal, respectively. The standard deviation of the amplitude of motion extrema between the Wiimote and RPM was 0.9 mm and the timing difference was 253 ms. CONCLUSION The performance of Wiimote shows promise for respiratory monitoring for its faster sampling rate as well as the potential optical and GPU abilities. If used with care it can deliver reasonable spatial and temporal accuracy.

Abstract
BACKGROUND AND PURPOSE Data on the possible association between cardiac right-to-left shunt (RLS) and cryptogenic stroke are lacking in Asians. RLS and its subtypes in Chinese cryptogenic stroke patients were investigated. METHODS Patients (n = 153, mean age 42 ± 10 years, 81 male) with cryptogenic stroke from four medical centers in China and 135 healthy volunteers (mean age 34 ± 8 years, 54 male) were recruited. Contrast transcranial Doppler was used to assess the prevalence of RLS. A three-level RLS categorization was applied as follows: none, 0 microbubbles (MBs); small, 1-25 MBs; and large, >25 MBs. RLS was considered latent if it occurred only after the Valsalva maneuver or permanent when it occurred also during normal respiration. RESULTS Overall, RLS (P = 0.02), large RLS (P < 0.001) and permanent RLS (P = 0.02) were more frequently detected in patients with cryptogenic stroke than in healthy volunteers. The prevalences of small RLS and latent RLS in the two groups were similar (22% vs. 21% and 11% vs. 10%, respectively). The proportion of large RLSs amongst the subjects with RLS was much higher in the patient group than in healthy volunteers (45% vs. 18%, P < 0.001), whilst the proportion of permanent RLS was similar (72% vs. 64%, P = 0.11). Most large RLSs in the patient group (22/27, 81%) were permanent RLSs. CONCLUSIONS Cardiac RLS is associated with cryptogenic stroke in Chinese. However, the higher prevalence of overall RLS in the patient group was mainly due to the increased proportion of large RLSs. The results only support large RLSs as a pathological condition.

Abstract
Aberrant immunity response contributes to the pathogenesis of acute-on-chronic hepatitis B liver failure. Tumour necrosis factor-α-induced protein-8 like-2 (TIPE2) is a recently identified molecular to maintain immune homoeostasis, but its role in acute-on-chronic hepatitis B liver failure (ACHBLF) is unknown. We detected TIPE2 mRNA levels in peripheral blood mononuclear cells (PBMCs) from 56 patients with ACHBLF, 60 chronic hepatitis B patients, 24 healthy controls and analysed its role in disease severity and prognosis. TIPE2 mRNA expression in patients with ACHBLF was higher than that of patients with chronic infection or healthy controls. In patients with ACHBLF, TIPE2 mRNA level was positively correlated with serum total bilirubin, international normalized ratio and model for end-stage liver disease scores. Furthermore, the level of TIPE2 mRNA was significantly higher in nonsurvivors than survivors in patients with ACHBLF. The mRNA level of TIPE2 gradually decreased week by week in survivors accompanied by recovery from patients with ACHBLF, while its expression sustained at high levels in nonsurvivors. TIPE2 mRNA level after lipopolysaccharide (LPS) stimulation ex vivo in patients with ACHBLF was higher compared with controls and patients with chronic infection. Meanwhile, cytokines ex vivo secreted were measured as a marker of immune activation. After LPS stimulation, interleukin (IL)-6 and tumour necrosis factor (TNF)-α mRNA expression were reduced in patients with ACHBLF, and a significantly negative correlation was found between TIPE2 and TNF-α mRNA levels. In conclusion, our results identified the potential role of TIPE2 in predicting disease progression and prognosis in patients with ACHBLF by negative regulating of cell-mediated immunity.

Abstract
The dynamic properties of the dipolar magnet CsGd(MoO4)2 have been studied. The frequency and temperature dependence of the AC susceptibility investigated in the paramagnetic region above 2 K revealed the co-existence of magnetic field induced slow and fast relaxation channels with a timescale differing by three orders of magnitude. The slow relaxation is determined by the properties of the first coordination sphere of the Gd(3+) ion and has the character of a two-phonon Orbach process. The fast relaxation is potentially attributed to a two-phonon Raman process realized via a localized phonon mode associated with the layered crystal structure. The temperature dependence of the phonon mean free path in zero magnetic field indicates significant phonon scattering below 1 K resulting from the combined effect of magnetic correlations and the scattering of dominant phonons with energies corresponding to the crystal-field levels.
