    ABSTRACT: We consider two entangled atoms, each of which is embedded in a coherent photonic-band-gap (PBG) reservoir. The effect of the atomic embedded position on the entanglement of the two-atom system is studied. We find that the embedded position of the atom plays an important role in the dynamics of entanglement. The variation of the atomic position can lead to the shift between entanglement sudden death and the entanglement trapping. We also consider the entanglement transfer between different subsystems. Our results could be applied to manipulation of entanglement in nanostructured materials.

    ABSTRACT: LaFe11.6Si1.4 samples were hydrogenated at the same initial hydrogen-filling pressure of 0.6 MPa and different temperatures (from 393 K to 478 K). The hydrogen absorption kinetics performance, phase structures and Curie temperature (TC) of these alloys were investigated. The results show that all samples have excellent hydrogen absorption kinetics performance, the NaZn13-type main structure of these LaFe11.6Si1.4Hy alloys is stable during the fore-and-aft hydrogenation processes and their TCs vary from 326.9 K to 277.7 K by adjusting hydrogen content from 1.26 to 0.936. The high-temperature hydrogenation can markedly save the hydrogen saturation time of LaFe11.6Si1.4 alloys and precisely adjust the TC of these alloys. In addition, the split of magnetocaloric transition is observed by analyzing Differential Scan Calorimetry curves of the alloys hydrogenated from 443 K to 463 K. Further investigation of two typical samples hydrogenated at 443 K and 463 K shows that the split transition peaks change into a sharp single transition peak after annealing these samples at 373 K for 24 h and the split transition peaks re-emerge after storing the annealed samples near TC for 14 days. The recovery and split of the peaks imply that the fully hydrogenated LaFe11.6Si1.4 alloys at high treatment temperature are all partially hydrogenated LaFe11.6Si1.4 alloys when stored or used at room temperature.

    ABSTRACT: To evaluate the potential effect of interaction between breastfeeding and environmental tobacco smoke (ETS) exposure on respiratory health, we studied 31,049 children (aged 2-to-14 years) from 25 districts of seven cities in northeast China. Parents of the children completed standardized questionnaires that characterized the children's histories of respiratory symptoms and illness, feeding methods, ETS exposure, and other associated risk factors. Breastfeeding was defined as having been exclusively breastfed for 3 months or more. The results showed that the association of ETS exposure with childhood respiratory conditions/diseases was modified by breastfeeding, and the association for non-breastfed children was stronger than for breastfed children. In particular, for non-breastfed children, the odds ratios (ORs) for the effect of current ETS exposure asthma was 1.71 (95% CI: 1.43-2.05); however, the ORs for breastfed children was 1.33 (95% CI: 1.20-1.48), indicating that the interactions between breastfeeding and current ETS exposure on asthma were statistically significant (P=0.019). When stratified by school (kindergarten vs. elementary school), breastfeeding was more protective for asthma-related symptoms among children from kindergarten. In conclusion, this study shows that breastfeeding is associated with smaller associations between ETS exposure and respiratory conditions in children, suggesting that breastfeeding reduces susceptibility to the respiratory effects of ETS.

    ABSTRACT: B lymphocytes use B cell receptors (BCRs) to sense the physical features of the antigens. However, the sensitivity and threshold for the activation of BCRs resulting from the stimulation by mechanical forces are unknown. Here we addressed this question using a double-stranded DNA based tension gauge tether system serving as a predefined mechanical force gauge ranging from 12 to 56 pN. We observed that IgM-BCR activation is dependent on mechanical forces and exhibits a multi-threshold effect. In contrast, the activation of isotype-switched IgG- or IgE-BCR only requires a low threshold of less than 12 pN, providing an explanation for their rapid activation in response to antigen stimulation. Mechanistically, we found that the cytoplasmic tail of the IgG-BCR heavy chain is both required and sufficient to account for the low mechanical force threshold. These results defined the mechanical force sensitivity and threshold that are required to activate different isotyped BCRs.

    ABSTRACT: Mesenchymal stem cells (MSC) are regarded as an attractive source of therapeutic stem cells for myocardial infarction. However, their limited self-renewal capacity, low migration capacity and poor viability after transplantation hamper the clinical use of MSC; thus, a strategy to enhance the biological functions of MSC is required. Exendin-4 (Ex-4), a glucagon-like peptide-1 receptor agonist, exerts cell-protective effects on many types of cells. However, little information is available regarding the influence of Ex-4 on MSC. In our study, MSC were isolated from bone marrow and cultured in vitro. After treatment with Ex-4, MSC displayed a higher proliferative capacity, increased C-X-C motif receptor 4 (CXCR4) expression and an enhanced migration response. Moreover, in H2O2-induced apoptosis, Ex-4 preserved mitochondrial function through scavenging ROS and balancing the expression of anti- and pro-apoptotic proteins, leading to the inhibition of the mitochondria-dependent cell death pathways and increased cell survival. Moreover, higher phospho-Akt (p-Akt) expression was observed after Ex-4 intervention. However, blockade of the PI3K/Akt pathway with inhibitors suppressed the above cytoprotective effects of Ex-4, suggesting that the PI3K/Akt pathway is partly responsible for Ex-4-mediated MSC growth, mobilization and survival. These findings provide an attractive method of maximizing the effectiveness of MSC-based therapies in clinical applications.

    ABSTRACT: The peroxisome proliferator-activated receptor -γ(PPARγ) has been identified in a wide range of cancers, including brain, breast, colon, stomach and lung cancers. It belongs to the thyroid/steroid hormone receptors superfamily. Binding with their special ligands, PPARγ plays important roles in regulating transcription of their target genes.PPARγ activation suppresses the growth of the tumor cells, implicating the anti-tumor potential of PPARγ ligand. Tumors in the nervous system are among the most devastating cancers. This review highlights key advances in understanding the effects of PPARγ ligands in the treatment of tumors in the nervous system.

    ABSTRACT: Cancer stem cells (CSCs) are cancer cells with characteristics of stem cells, especially the ability to arise to all types of cell in a particular cancer tissue. With the capacity to generate multiple types of cancer cells, CSCs are proposed as primary impetus for tumor initiation and metastases and are suggested as potential therapeutic targets for anti-cancer treatment. Peroxisome-proliferator-activated receptors (PPARs) are a subset of multifunctional transcription factors which play a pivotal role in cancer development and tumorigenesis. PPARs are also reported to be involved in the modulation of the epithelial-mesenchymal transition (EMT) process in CSC initiation and in the regulation of CSC functions. However, the exact mechanisms remain unknown. Herein we review the latest evidence on the regulatory effects and mechanisms of PPARs in CSC formation and function, and evaluate the prospects of PPARs as a target for cancer treatment.

    ABSTRACT: The pluripotent mesenchymal stem cells (MSC) are common precursors to adipocytes and osteoblasts. Large numbers of extracellular and intracellular signals and transcription factors moderate adipogenesis and osteo-blastogenesis. Importantly, between adipogenic and osteogenic lineage commitment and differentiation, differentiation of MSCs into one lineage will inhibit their differentiation toward the other lineage. This balance is regulated by numerous signaling pathways. As we know, the peroxisome-proliferator-activated receptor-γ (PPAR-γ) and Wnt/β-catenin pathway are regarded as the master moderators of adipogenesis and osteogenesis. Moreover, governing the differentiation of MSCs to adipogenesis and osteoblastogenesis has significant implications in diverse areas of human health, from obesity to regenerative medicine to osteoporosis. Rivalry roles have been reported of the two pathways since the downstream products activated by Wnt-5arepress PPAR-γ transactivation through the H3K9 histone methyltransferase protein complexes. This review will discussthe inductive and inhibitive role of PPAR-γ in adipogenesis and osteoblastogenesis respectively, as well as the canonical Wnt/β-catenin pathway.

    ABSTRACT: Cellular senescence of endothelial cells is a damage and stress response which induces pro-inflammatory, pro-atherosclerotic, and pro-thrombotic phenotypes. Donepezil is a drug used for the treatment of mild to moderate dementia of the Alzheimer's disease (AD). The aim of the present study was to investigate the attenuation of endothelial cell senescence by donepezil and to explore the mechanisms underlying the anti-aging effects of donepezil. Our results indicated that high glucose (HG) markedly decreased cell viability of human umbilical vein endothelial cells (HUVECs), and this phenomenon was reversed by treatment with donepezil. Importantly, our results displayed that the frequency of senescent (SA-ß-gal-positive) cells and the expression level of senescence genes (PAI-1 and p21) were significantly higher in the HG group compared with the normal glucose (NG) group, and these changes were blocked by treatment with donepezil. Also, our results showed that donepezil inhibits the generation of reactive oxygen species (ROS), which promotes cellular senescence. Pretreatment with nicotinamide (NAM), a sirtuin 1 (SIRT1) inhibitor, inhibited the reduction in senescence associated with donepezil. Indeed, our results indicated that donepezil increased the SIRT1 enzyme activity. Therefore, these results show that donepezil delays cellular senescence that is promoted under HG condition via activation of SIRT1.

    ABSTRACT: To access left ventricular global deformation abnormalities during low-dose dobutamine stress test (DSE) by three-dimensional speckle-tracking echocardiography(3D-STE)in patients with non-ST-elevation acute coronary syndrome (NSTE-ACS), and explore the diagnostic value of 3D-STE combined with DES for NSTE-ACS. Forty-nine patients with suspected NSTE-ACS underwent DSE and coronary angiography with an initial dobutamine dose of 5 µg·kg(-1)·min(-1), which was doubled at 3-min intervals to the peak dose of 20 µg·kg(-1)·min(-1). The global longitudinal strain (GLS), global circumferential strain (GCS), territory longitudinal strain (TLS), and territory circumferential strain (TCS) of the left ventricular subendocardial myocardium were measured with 3D-STE at rest and at the peak-dose stage. Conventional echocardiography and 3D-STE parameters and their changes during DSE were evaluated, and their diagnostic values were analyzed according to the receiver-operating characteristic (ROC) curves. All the patients completed DSE uneventfully and 3D-STE showed a good reproducibility of the results. Compared with patients with non-NSTE-ACS, NSTE-ACS patients showed obviously reduced resting left ventricular global deformation function especially in terms of circumferential deformation (P<0.05); the ROC curves for the parameters were similar between the two groups (P>0.05). During DSE, the global deformation differences between the two groups further increased (P<0.01), and the diagnostic values of the peak-dose stage parameters were significantly greater than those of the resting parameters. ROC curves analysis showed that TLS and TCS at peak-dose stage had the highest diagnostic value for NSTE-ACS. 3D-STE combined with low-dose DSE is a safe and effective noninvasive technique for accessing and identifying NSTE-ACS, and DSE can significantly enhance the diagnostic value of 3D-STE.

    ABSTRACT: Although the association of Helicobacter pylori (H. pylori) infection with diabetes mellitus has been evaluated, findings are controversial. This study investigated the association in a Chinese population. A cross-sectional study, including a total of 30,810 subjects from the Dongfeng-Tongji Cohort study was conducted. H. pylori status was measured via (14) C urea breath test. Association analysis was performed by logistic regression, with multivariable adjustment for sex, age, BMI, smoking, alcohol consumption, family history of diabetes, physical activity, and the use of antibiotics. Among a middle- and old-age Chinese population, Individuals with H. pylori infection also had a higher prevalence of type 2 diabetes (21.3% vs.20.2%, P = 0.026). H. pylori infection was associated with higher risk of type 2 diabetes (OR, 1.08 [95% CI: 1.02-1.14]; P = 0.008) after adjustment for other confounders. The association was significant among females, those who were above 65 years old, not overweight or obese, and those who did not smoke, did not consume alcohol and without family history of diabetes. However, there was no interaction between H. pylori infection and other traditional risk factors on type 2 diabetes risk. Subjects with H. pylori infection had a lower level of HDL cholesterol (P < 0.0001) and higher levels of blood pressure (P < 0.001), total cholesterol, HbA1c and fasting blood glucose (P < 0.0001) than those who did not. These findings suggested that H. pylori infection was associated with the risk of type 2 diabetes in a middle- and old-age Chinese population. This article is protected by copyright.

    ABSTRACT: Many studies have shown the relationship between serum Club cell secretory protein-16 (CC16) and respiratory diseases. However, little research has been done to study urinary CC16 in relation to respiratory diseases. Our objective was to examine the association of urinary CC16 and physician-diagnosed asthma or lung function measurements in Chinese children. A total of 147 physician-diagnosed children with asthma, ages 9-15 years, were recruited from our cross-sectional study population in northeast China. The 390 healthy children who were not asthmatic and not smokers were selected at random from the population according to 10% proportional sampling. Lung function values, including forced expiratory volume in 1 second and forced vital capacity were measured with two portable spirometers. Urine CC16 was determined by using an enzyme-link immunoassay kit. The relationships between urine CC16 levels and asthma, lung function were assessed by multiple regression models. The geometric mean (95% confidence interval [CI]) creatinine-adjusted urine CC16 level was, for creatinine, 9.77 ng/mg (95% CI, 8.12-12.02 ng/mg). After adjustments for sex, age, body mass index, parental education, and smoking status, lower urine CC16 levels were found to be associated with asthma (odds ratio 0.782 [95% CI, 0.617- 0.990]). A positive association was found between urine CC16 and forced vital capacity (beta 0.064 [95% CI, 0.008-0.119]). Our study demonstrated lower levels of urine CC16 and lung function in patients with asthma than in those patients without asthma. CC16 in urine may be a useful tool or biomarker for investigating lung epithelium integrity among children with asthma or lung injury.

    ABSTRACT: As the complexity of communications and signal processing systems increases, so does the number of blocks or elements that they have. In many cases, some of those elements operate in parallel, performing the same processing on different signals. A typical example of those elements are digital filters. The increase in complexity also poses reliability challenges and creates the need for fault-tolerant implementations. A scheme based on error correction coding has been recently proposed to protect parallel filters. In that scheme, each filter is treated as a bit, and redundant filters that act as parity check bits are introduced to detect and correct errors. In this brief, the idea of applying coding techniques to protect parallel filters is addressed in a more general way. In particular, it is shown that the fact that filter inputs and outputs are not bits but numbers enables a more efficient protection. This reduces the protection overhead and makes the number of redundant filters independent of the number of parallel filters. The proposed scheme is first described and then illustrated with two case studies. Finally, both the effectiveness in protecting against errors and the cost are evaluated for a field-programmable gate array implementation.

    ABSTRACT: Pure-phase (K, Na)NbO3 (KNN) powders with orthorhombic symmetry were successfully synthesized by solvothermal method using isopropanol as solvent, without the addition of water. The asprepared powders were characterized by X-ray diffraction, scanning electron microscopy and energy dispersive spectrometry to show the variation of phase, morphology, size distribution and chemical composition under different synthetic conditions, such as fill factors (FF) of the solvothermal system and alkalinity of the starting solution. Compared with the traditional hydrothermal method and the so-called solvothermal method (water aided in fact), small grains with well crystallinity were obtained using 100% isopropanol as reaction medium. The results indicate that both fill factor and alkalinity have significant effects on the phase structure and size distribution of the as-obtained KNN powders. Pure orthorhombic perovskite-structured KNN powders with a grain size of 100 nm were synthesized at the following condition: reaction time, 16 h; reaction temperature, 240 °C; fill factor, 70%; and alkalinity, 1 M. Small grains (∼100 nm) tend to form mesocrystals (∼ 10 μm) with tetrakaidecahedron structures, and the possible formationmechanism was proposed. The solvothermal method without the addition of water is a promising alternative to synthesize pure and refined powders under mild reaction conditions.

    ABSTRACT: This paper studies the allocation of information flows in noiseless, memoryless communication networks in the presence of omniscient Byzantine adversary. In such networks, adversary may maliciously modify some edge-flows, and legitimate users should resort to network error correction strategies to transmit data reliably. Unlike prior papers, which focused on the capacities of the networks, we consider the expense of resources used by the flow. Hereby, this paper uses an optimization problem to define the concept of minimum cost network error correction flows. We provide a necessary and sufficient condition of feasibility of the allocation problem, and derive a cut-set outer bound on the feasible region. Using this cut-set bound, we can find the minimum cost network error correction flow in some instances. Moreover, we also consider the relationship between incoming edge-flows and outgoing edgeflows of a vertex. As for the directed acyclic graphs, we propose an algorithm to allocate the network error correction flow. This algorithm is with polynomial time complexity, and proves to be optimal when recoding at intermediate nodes is forbidden. Additionally, in order to justify the necessity of recoding at intermediate nodes, we analyze the benefit of intermediate recoding. On the one hand, we construct a series of instances to prove that intermediate recoding can bring enormous benefits in some networks. On the other hand, numerical analysis shows that the benefit is modest in small random graphs.

    ABSTRACT: Little information exists regarding the effect of interaction of obesity and long-term air pollution exposure on children's blood pressure and hypertension in areas with high levels of air pollution. The aim of this study is to assess effect modification by obesity on the association between exposure and blood pressure in Chinese children. We studied 9,354 Chinese children, ages 5-17 years old, from 24 elementary schools and 24 middle schools in the Seven Northeastern Cities during 2012-2013. Four-year average concentrations of particles with an aerodynamic diameter ≤10 µm (PM10), sulfur dioxide, nitrogen dioxides, and ozone (O3) were measured at the monitoring stations in the 24 districts. We used generalized additive models and two-level logistic regression models to examine the health effects. Consistent interactions were found between exposure and obesity on blood pressure and hypertension. The association between exposure and hypertension was consistently larger for overweight/obese children than for children with normal-weight, with odds ratios for hypertension ranging from 1.16 per 46.3μg/m for O3 (95% confidence interval [CI] = 1.12, 1.20) to 2.91 per 30.6μg/m for PM10 (95% CI = 2.32, 3.64), and estimated increases in mean systolic and diastolic blood pressure ranging from 0.57 mmHg (95% CI = 0.36, 0.78) and 0.63 mmHg (95% CI = 0.46, 0.81) per 46.3 μg/m for O3 to 4.04 mmHg (95% CI = 3.00, 5.09) and 2.02 mmHg (95% CI = 1.14, 2.89) per 23.4 μg/m for sulfur dioxide. Obesity amplifies the association of long-term air pollution exposure with blood pressure and hypertension in Chinese children.

    ABSTRACT: To assess whether pre-pregnancy body mass index (BMI) modify the relationship between gestational weight gain (GWG) and child birth weight (specifically, presence or absence of low birth weight (LBW) or presence of absence of macrosomia), and estimates of the relative risk of macrosomia and LBW based on pre-pregnancy BMI were controlled in Wuhan, China. From June 30, 2011 to June 30, 2013. All data was collected and available from the perinatal health care system. Logistic regression models were used to estimate the independent association among pregnancy weight gain, LBW, normal birth weight, and macrosomia within different pre-pregnancy BMI groups. We built different logistic models for the 2009 Institute of Medicine (IOM) Guidelines and Chinese-recommended GWG which was made from this sample. The Chinese-recommended GWG was derived from the quartile values (25th-75th percentiles) of weight gain at the time of delivery in the subjects which comprised our sample. For LBW children, using the recommended weight gain of the IOM and Chinese women as a reference, the OR for a pregnancy weight gain below recommendations resulted in a positive relationship for lean and normal weight women, but not for overweight and obese women. For macrosomia, considering the IOM's recommended weight gain as a reference, the OR magnitude for pregnancy weight gain above recommendations resulted in a positive correlation for all women. The OR for a pregnancy weight gain below recommendations resulted in a negative relationship for normal BMI and lean women, but not for overweight and obese women based on the IOM recommendations, significant based on the recommended pregnancy weight gain for Chinese women. Of normal weight children, 56.6% were above the GWG based on IOM recommendations, but 26.97% of normal weight children were above the GWG based on Chinese recommendations. A GWG above IOM recommendations might not be helpful for Chinese women. We need unified criteria to classify adult BMI and to expand the sample size to improve representation and to elucidate the relationship between GWG and related outcomes for developing a Chinese GWG recommendation.

    ABSTRACT: Hepatitis B can be effectively prevented by hepatitis B vaccination. However, hyporesponse to the hepatitis B vaccine has been found in both human and inbred mice with particular MHC alleles or haplotypes, but the mechanisms underlying this poor response remains elusive. In the present study, we investigated the mechanisms underlying the hyporesponse to hepatitis B vaccination using B10.S-H2s/SgMcdJ (B10.S, H-2(s), poor responder) and C57BL/10J (B10, H-2(b), good responder) mice. We observed that the B10.S mice displayed a hyporesponse to HBsAg vaccine but a normal response to three other foreign antigens (influenza A (H1N1) 2009 monovalent vaccine, tetanus toxoid and ovalbumin). In B10.S mice immunized with HBsAg, the levels of serum anti-HBs IgG, the number of HBsAg-specific IgG-secreting plasma cells and HBsAg-specific Th cells were considerably lower than that in B10 mice. Further, the findings of the insufficient maturation (CD86), co-stimulation (CD40) and migration (CCR7) activities of DCs together with the inadequate activation of the HBsAg-specific Th cells by APCs were identified as part of the reason for the HBsAg hyporesponse in B10.S mice, which supports the hypothesis that measures aimed at promoting the maturation, co-stimulation or migration of APCs to enhance Th cell activation may be a useful strategy for the development of new hepatitis B vaccines.

    ABSTRACT: In this paper, the resource allocation for multiuser wiretap Orthogonal Frequency-Division Multiplexing(OFDM) systems is investigated to improve the system power efficiency. In such a multiuser wiretap OFDM system, one legitimate transmitter (Alice), multiple legitimate receivers (Bobs), and one eavesdropper (Eve) are simultaneously considered. The time-domain artificial noise (AN) is firstly involved to guarantee the target secrecy rates of multiple Bobs. Different from the traditional sum secrecy rate maximization problem which may result in the unfair transition for Bobs with bad channel gains and more transmit power consumptions, a non-convex transmit power minimization problem is formulated to jointly optimize the power, subcarrier allocation and AN design, in which a target secrecy rate for each individual Bob is ensured. An iterative algorithm is further proposed to solve this power minimization problem by updating the subcarrier, power allocation and AN design alternatively. Numerical simulation results demonstrate the effectiveness of the proposal, including the improvements of system power efficiency and the fairness of multiple Bobs. 1

    ABSTRACT: Food frequency questionnaire (FFQ) is a reliable tool to estimate dietary intake in large nutritional epidemiological studies, but there is lack of a current and validated FFQ for use in urban Chinese pregnant women. This study aimed to evaluate the reproducibility and validity of a semi-quantitative FFQ designed to estimate dietary intake among urban pregnant women in a cohort study conducted in central China. In the reproducibility study, a sample of 123 healthy pregnant women completed the first FFQ at 12-13 weeks gestation and the second FFQ 3-4 weeks later. To validate the FFQ, the pregnant women completed three 24-h recalls (24 h) between the intervals of two FFQs. The intraclass correlation coefficients of two administrations of FFQ for foods ranged from 0.23 (nuts) to 0.49 (fruits) and for nutrients from 0.24 (iodine) to 0.58 (selenium) and coefficients were all statistically significant. The unadjusted Pearson correlation coefficients between two methods ranged from 0.28 (beans) to 0.53 (fruits) for foods and from 0.15 (iodine) to 0.59 (protein) for nutrients. Energy-adjusted and de-attenuated correlation coefficients for foods ranged from 0.35 (beans) to 0.56 (fruits) and for nutrients from 0.11 (iodine) to 0.63 (protein), and all correlations being statistically significant except for iodine, sodium and riboflavin. On average, 67.0 % (51.2 %-80.5 %) of women were classified by both methods into the same or adjacent quintiles based on their food intakes, while 68.5 % (56.1 %-77.2 %) of women were classified as such based on nutrient intakes. Extreme misclassifications were very low for both foods (average of 2.0 %) and nutrients (average of 2.2 %). Bland-Altman Plots also showed reasonably acceptable agreement between two methods. This FFQ is a reasonably reliable and valid tool for assessing most food and nutrient intakes of urban pregnant women in central China.
