Abstract
Graphene nanoribbons (GNR) are one of the most promising candidates for the fabrication of graphene-based nanoelectronic devices such as high mobility field effect transistors (FET). Here, we report a high-yield fabrication of a high quality another type of GNR analogue, fully flattened carbon nanotubes (flattened CNTs), using solution-phase extraction of inner tubes from large-diameter multi-wall CNTs (MWCNTs). Transmission electron microscopy (TEM) observations show that flattened CNTs have width of typically 20 nm and a barbell-like cross section. Measurements of the low-bias conductance of isolated flattened CNTs as a function of gate voltage shows that the flattened CNTs display ambipolar conduction which is different from those of MWCNTs. The estimated gap based on temperature dependence of conductivity measurements of isolated flattened CNTs is 13.7 meV, which is probably caused by the modified electronic structure due to the flattening.

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
In the human immune system, T-helper cells are able to differentiate into two lymphocyte subsets: Th1 and Th2. The intracellular signaling pathways of differentiation form a dynamic regulation network by secreting distinctive types of cytokines, while differentiation is regulated by two major gene loci: T-bet and GATA-3. We developed a system dynamics model to simulate the differentiation and re-differentiation process of T-helper cells, based on gene expression levels of T-bet and GATA-3 during differentiation of these cells. We arrived at three ultimate states of the model and came to the conclusion that cell differentiation potential exists as long as the system dynamics is at an unstable equilibrium point; the T-helper cells will no longer have the potential of differentiation when the model reaches a stable equilibrium point. In addition, the time lag caused by expression of transcription factors can lead to oscillations in the secretion of cytokines during differentiation.

Abstract
BACKGROUND Given the important role of the default mode network (DMN) in cognitive function and the well-known neurocognitive deficit in schizophrenia, it is intriguing to examine systematically the relationship between neurocognitive dysfunction and aberrant intrinsic activities, and also functional connectivity, of the DMN in patients with schizophrenia. Method First-episode, treatment-naive patients with schizophrenia (FES) (n = 115) and healthy controls (n = 113) underwent resting-state functional magnetic resonance imaging (fMRI) scans and neurocognitive tests. Intrinsic neural activities evaluated by using the fragment amplitude of low-frequency fluctuations (fALFF) and the resting-state functional connectivity assessed by seed-based correlational analysis were compared between patients and controls. Aberrant intrinsic activities and DMN connectivity in patients were then correlated to neurocognitive performance and clinical symptoms. RESULTS Compared to controls, patients with FES showed decreased fALFF in the bilateral medial prefrontal cortex (MPFC) and the orbitofrontal cortex (OFC), and increased fALFF in the bilateral putamen. Increased functional connectivity with the DMN was observed in the left insula and bilateral dorsolateral PFC (DLPFC) in patients with FES. In patients, aberrant fALFF in the bilateral OFC were correlated with cognitive processing speed; fALFF in the left OFC and right putamen were correlated with the clinical factors excited/activation and disorganization; and increased DMN functional connectivity in the left insula was correlated with the clinical factors positive, excited/activation, disorganization and neurocognitive deficit in the domain of sustained attention. CONCLUSIONS These associations between neurocognitive dysfunction and aberrant intrinsic activities, and also functional connectivity, of the DMN in patients with schizophrenia may provide important insights into the neural mechanism of the disease.

Abstract
BACKGROUND Prostate cancer (PCa) gene expression marker 1 (PCGEM1), a long noncoding RNA, has drawn increasing attention for its important role in PCa. However, the association between genetic variations in the PCGEM1 gene and risk of PCa has not been investigated yet. METHODS We investigated the effect of two tagging single-nucleotide polymorphism (tSNPs; rs6434568 and rs16834898) in PCGEM1 gene on PCa risk in the Chinese men. Odds ratios (ORs) with 95% confidence intervals (CIs) were used to assess the association. RESULTS We found a significantly decreased risk of PCa for rs6434568 AC and AC/AA genotype (adjusted OR=0.76, 95% CI=0.60-0.97 for AC; adjusted OR=0.76, 95% CI=0.61-0.96 for AC/AA), as well as rs16834898 AC and AC/CC genotype (adjusted OR=0.76, 95% CI=0.59-0.97 for AC; adjusted OR=0.79, 95% CI=0.62-0.99 for AC/CC), compared with the CC and AA genotypes, respectively. When we evaluated these two tSNPs together based on the risk alleles (that is, rs6434568 C and rs16834898 A), we found that the combined genotypes with four risk alleles were associated with an increased risk of PCa compared with those carrying 0-3 risk alleles (1.53, 1.19-1.97), and this increased risk was more pronounced among subjects of≤70 years (1.80, 1.24-2.62), Gleason score≥7 (1.68, 1.28-2.22) and PSA level≥20 (1.64, 1.24-2.18). CONCLUSIONS Our results indicated that PCGEM1 polymorphisms may contribute to PCa risk in Chinese men. Additional functional analyses are required to detect the detailed mechanism underlying the observed association.

Abstract
This study was conducted to determine the pharmacokinetic characteristics of bulleyaconitine A (BLA) after oral gavage and intravenous administration of BLA at a single dose of 0.04, 0.12, 0.36 mg/kg (oral) or 0.02 mg/kg (i.v.) in male Sprague-Dawley rats. Plasma concentration profiles were analysed using a non-compartmental pharmacokinetic method. Following i.v. 0.02 mg/kg and oral administration 0.04, 0.12 or 0.36 mg/kg, the geometric mean Cmax values were 19.97, 2.11, 5.11 and 11.47 ng/ml, respectively; the corresponding geometric mean AUC(0-t) values were 10.50, 3.19, 9.59 and 18.10 ng x h/ml, respectively. The median Tmax values were 0.033, 0.167, 0.167 and 0.167 h, respectively. The terminal elimination half-lives (t1/2) were 1.23, 2.48, 1.93 and 2.17h, respectively. The results showed that Cmax and AUC(0-t) increased with increasing doses of BLA. The increase in exposure with increasing dose was lower than expected under conditions of strict proportionality.

Abstract
Hemoglobin (Hb) is the major protein component of erythrocytes in animals with red blood, although it can serve additional functions beyond the transport of oxygen. The blood clam (Tegillarca granosa) is one of the few mollusks that has Hb, although the structure and function of molluskan Hbs remain unclear. We characterized two unique and highly compartmentalized blood clam hemoglobin genes, Tg-HbIIA and Tg-HbIIB, at the molecular level. The full-length cDNA of Tg-HbIIA was 731 bp with a 450-bp open reading frame encoding 150 amino acids; that of Tg-HbIIB was 698 bp, with a 456-bp open reading frame encoding 152 amino acids. Their intronic regions were amplified by PCR. The two genes showed the typical 2 intron/3 exon organization found in T. granosa. The 3-D structures of the three blood clam Tg-Hbs were predicted using the SWISS-MODEL Protein Modeling Server, and a phylogenetic analysis was conducted to investigate its evolution. As quantified by qRT-PCR, the expression levels of Tg-HbIIA and Tg-HbIIB were significantly upregulated upon challenge by Vibrio parahaemolyticus, lipopolysaccharides, and peptidoglycans. Three Hb isoforms, Tg-HbI, Tg-HbIIA, and Tg-HbIIB, were found. Specific structures and evolutionary features were found in these molluskan Hb genes. Challenge experiments indicated that Tg-Hbs are involved in immune defense responses against bacterial infection and bacterial pathogenic factors. As this is the first functional research on Hb genes in the blood clam, our findings provide new insight into the innate immune defense mechanisms of T. granosa.

Abstract
BACKGROUND AND OBJECTIVE Diabetes mellitus is believed to increase the risk and severity of periodontitis. However, less evidence is available on the converse effects of periodontitis on diabetes. The objective of the study was to investigate to what degree experimental periodontitis induced by Porphyromonas gingivalis might influence the onset and severity of diabetes in different mouse models. MATERIAL AND METHODS Twenty-eight male Tallyho/JngJ mice (type 2 diabetes), 20 male streptozotocin-induced diabetes C57BL/6J mice (type 1 diabetes) and 20 male C57BL/6J mice at 4 wks of age were evenly divided into two groups: periodontal infection and sham infection. Periodontitis was induced by Porphyromonas gingivalis W50 (P. gingivalis) oral inoculation before the development of diabetes. Sham-infected mice received vehicle as control. P. gingivalis in the oral cavity were identified by quantitative polymerase chain reaction. Fasting glucose, body weight and food intake levels were monitored and glucose tolerance tests were performed to assess glucose homeostasis for the onset and progression of diabetes. The level of alveolar bone loss and tumor necrosis factor-alpha were determined in week 20 when mice were killed. RESULTS Mice in the infection groups developed more alveolar bone loss than those in sham-infection groups (Tallyho p = 0.021; C57-STZ p = 0.014; C57 p = 0.035). Hyperglycemic mice exhibited significantly more bone loss compared to those normal glucose mice (Tallyho vs. C57 p = 0.029; C57-STZ vs. C57 p = 0.024). The level of tumor necrosis factor-alpha was consistent with that of periodontal bone loss and hyperglycemia. There was no significant effect of mouse species on the amount of bone loss at the same level of blood glucose. No statistically significant difference or trend in glucose metabolism was found between the infection and sham-infection group. CONCLUSION Diabetes enhanced the risk for periodontal disease induced by P. gingivalis. However, no converse impact was found between this periodontal infection and onset and severity of diabetes in both type 1 and 2 diabetes mice.

Abstract
Based on 106×10(6)ψ(3686) events collected with the BESIII detector at the BEPCII facility, a partial wave analysis of ψ(3686)→ppπ0 is performed. The branching fraction of this channel has been determined to be B(ψ(3686)→ppπ0)=(1.65±0.03±0.15)×10(-4). In this decay, 7 N* intermediate resonances are observed. Among these, two new resonances, N(2300) and N(2570) are significant, one 1/2+ resonance with a mass of 2300(-30-0)(+40+109) MeV/c2 and width of 340(-30-58)(+30+110) MeV/c2, and one 5/2- resonance with a mass of 2570(-10-10)(+19+34) MeV/c2 and width of 250(-24-21)(+14+69) MeV/c2. For the remaining 5 N* intermediate resonances [N(1440), N(1520), N(1535), N(1650) and N(1720)], the analysis yields mass and width values that are consistent with those from established resonances.

Abstract
PURPOSE Gestational hypertension (GH) is a serious health hazard for pregnant women and fetuses. The incidence of GH involves many epidemiological, biochemical, and hemodynamic factors. METHODS The current study investigated the GH risk under the influence of epidemiological, biochemical, and hemodynamic factors, and designed corresponding GH risk evaluation methods and apparatus. RESULTS The evaluation method has 74.15% sensitivity and 81.84% specificity. The ROC area under the curve is 0.841. The apparatus automatically imports epidemiological, biochemical, and hemodynamic factors, and then expresses the GH risk as numbers, bar codes, and colors through logic array analysis. CONCLUSION The GH risk value can effectively give the risk level of GH. The GH risk barcode can improve the degree of automation of information storage, transmission, and identification in GH monitoring. The GH risk color can also improve the GH macro description.

Abstract
We investigate properties of dark solitons under competing nonlocal cubic-local quintic nonlinearities. Analytical results, based on a variational approach and confirmed by direct numerical simulations, reveal the existence of a unique dark soliton solutions with their width being independent of the degree of nonlocality, due to the competing cubic-quintic nonlinearities.
