Abstract
The PHENIX experiment has measured electrons and positrons at midrapidity from the decays of hadrons containing charm and bottom quarks produced in d+Au and p+p collisions at sqrt[S(NN)]=200 GeV in the transverse-momentum range 0.85 ≤ p(T)(e) ≤ 8.5 GeV/c. In central d+Au collisions, the nuclear modification factor R(dA) at 1.5<p(T)<5 GeV/c displays evidence of enhancement of these electrons, relative to those produced in p+p collisions, and shows that the mass-dependent Cronin enhancement observed at the Relativistic Heavy Ion Collider extends to the heavy D meson family. A comparison with the neutral-pion data suggests that the difference in cold-nuclear-matter effects on light- and heavy-flavor mesons could contribute to the observed differences between the π(0) and heavy-flavor-electron nuclear modification factors R(AA).

Abstract
Mahogunin is an important mediator of chromogenesis and neurodegeneration. Mahoganoid is a mutation of the mahogunin gene, which causes a pleiotropic phenotype that includes suppression of obesity, spongiform neurodegeneration and improvement of insulin sensitivity. Our previous research found that mahoganoid widely expressed in the male rat reproductive system, and mahoganoid-deficient mice have reduced embryonic viability. But the reproductive change in mahogunin knockout (md(nc) ) male mice has not been reported previously. Here, we report that the mahogunin mRNA also widely exists in reproductive system of male mice, and its mRNA expression in the testis was in accordance with the first spermatogenesis wave cycle. Moreover, we find that md(nc) male mice were able to mate with females but no pups are delivered. Besides, the sperms' active progressive motility and hormone secretion (E2, FSH, LH, PRL) were obviously decreased while abnormal sperm rate showed no significant difference in md(nc) compared to wild-type (WT) male mice. This study indicates the mahogunin deficiency results in the infertility of male mice, disruption of hormones secretion and impaired active progressive motility, which may additionally illuminate the aetiology of male infertility in human.

Abstract
Neutral-pion π(0) spectra were measured at midrapidity (|y|<0.35) in Au+Au collisions at √(s(NN))=39 and 62.4 GeV and compared with earlier measurements at 200 GeV in a transverse-momentum range of 1<p(T)<10 GeV/c. The high-p(T) tail is well described by a power law in all cases, and the powers decrease significantly with decreasing center-of-mass energy. The change of powers is very similar to that observed in the corresponding spectra for p+p collisions. The nuclear modification factors (R(AA)) show significant suppression, with a distinct energy, centrality, and p(T) dependence. Above p(T)=7 GeV/c, R(AA) is similar for √(s(NN))=62.4 and 200 GeV at all centralities. Perturbative-quantum-chromodynamics calculations that describe R(AA) well at 200 GeV fail to describe the 39 GeV data, raising the possibility that, for the same p(T) region, the relative importance of initial-state effects and soft processes increases at lower energies. The p(T) range where π(0) spectra in central Au+Au collisions have the same power as in p+p collisions is ≈5 and 7 GeV/c for √(s(NN))=200 and 62.4 GeV, respectively. For the √(s(NN))=39 GeV data, it is not clear whether such a region is reached, and the x(T) dependence of the x(T)-scaling power-law exponent is very different from that observed in the √(s(NN))=62 and 200 GeV data, providing further evidence that initial-state effects and soft processes mask the in-medium suppression of hard-scattered partons to higher p(T) as the collision energy decreases.

Abstract
BACKGROUND Intestinal ischemia-reperfusion (I/R) is a common and serious clinical condition. Lactoferrin (Lf) has displayed antioxidative and anti-inflammatory activities in protecting the intestinal mucosa. The objective of this study was to investigate whether oral administration of Lf could attenuate I/R-induced intestinal injury. METHODS The experimental design consisted of three groups of Wistar rats (24 per group): sham operation, control (I/R, saline), Lf (I/R, Lf). Intestinal I/R was produced by occlusion of the superior mesenteric artery for 45 min. Eight rats from each group were randomly sacrificed 3, 12 or 36 h after reperfusion, and blood and intestinal samples were collected. RESULTS Intestinal I/R resulted in gut damage evidenced by morphological alteration, reduction of γ-glutamyl transpeptidase (γ-GGT) activity and increased cell apoptosis. Daily administration of Lf (200 mg/kg) for 14 days before surgery significantly attenuated gut damage by reducing the histologic score and apoptosis index, and restoring intestinal γ-GGT activity. Lf reduced intestinal malondialdehyde and myeloperoxidase, restored glutathione and decreased serum levels of tumor necrosis factor-α, interleukin (IL)-1β and IL-6 compared with saline control in I/R rats. In addition, oral administration of Lf did not produce any significant effects in healthy rats; Lf at doses of 50 or 100 mg/kg also attenuated I/R-induced gut damage, but administration of Lf for 7 days did not exert a significant protective effect against I/R-induced gut damage. CONCLUSIONS These results indicate that Lf may serve as a potent supplement in protecting the gut from intestinal I/R-induced injury by its antioxidative, anti-inflammatory and antiapoptotic activities.

Abstract
BACKGROUND To analyze circulating lung cancer cells in the peripheral blood in patients with lung cancer by flow cytometry (FCM). METHODS The monocyte fraction in peripheral blood was isolated by Ficoll-Hypaque gradient centrifugation. The cells obtained were labeled with antibodies against CD45, cytokeratin (CK) and antigen (2F7/S5A). The CD45(-) CK(+) 2F7/S5A(+) cells were analyzed by FCM. RESULTS Fifty cases out of 165 patients with lung cancer (30.30%) were found to have cancer cells in the peripheral blood. Positive rate in non-small cell lung cancer was 30.67%(45/150) and that in small cell lung cancer was 33.33%(5/15) respectively. Meanwhile, there was distinct correlation between detective rate of cancer cells in the peripheral blood and pathological stage(P<0.05). CONCLUSIONS Examination of lung cancer presented in the peripheral blood by FCM might be helpful for staging and finding metastatic potential of lung cancer.

Abstract
In mammalian cells, the mitochondrial pathway of apoptosis plays a key role in various biological processes and has been extensively studied. One of the signature features of this pathway is permeabilization of the outer mitochondrial membrane (MOMP) and thus release of cytochrome c into the cytoplasm to trigger subsequent activation of executioner caspases. Because MOMP is associated with loss of mitochondrial function, it has long been believed to represent an irreversible commitment to cell death. However, emerging data over the last decade has indicated that induction of MOMP alone is not always sufficient to fully commit cells to death. As such, it becomes important to understand how apoptosis is regulated post-MOMP. Here we recount evidence investigating if and how cells can survive MOMP, and why this might have important physiological consequences. Furthermore, we review recent progress made in understanding how the pathway is regulated beyond MOMP and cytochrome c release. This article is part of a Special Issue entitled "Apoptosis: Four Decades Later".

Abstract
BACKGROUND Recently, many observations have drawn researchers' attention to study drug resistance and invasion/metastasis as a single entity. However, little evidence is available about the relationship between the multiple drug resistance (MDR) and invasion so far. AIM To study the relationship between the multiple drug resistance and invasive-metastatic phenotypes in cancer cells. MATERIALS AND METHODS In this study, we compared the biological alterations of drug-resistant cells with their parental control and demonstrated that the drug-resistant cells have acquired enhanced invasive ability in addition to their acquired MDR phenotype. RESULTS Motility and invasiveness assays revealed that MCF-7 / Adr had an invasive phenotype. Light and electron microscopy showed loss of cell-cell clustering after trypsinization, loss of tight junctions and desmosomes, ultrastructural changes to the actin network and nucleus, loss of epithelial characters, and increase in filopodia in the drug resistant cell line. A major component of cell-cell junctions, E-cadherin, was shown to be expressed on the protein and RNA levels in MCF-7 but not MDF-7 / Adr cells. More protrusions (pseudopodia) on the cell surface were found in MCF-7 / Adr cells, which enable the cells to migrate and invade / metastasize. Examination of ultrastructural morphology revealed that great changes occurred in drug resistant cancer cells including absence of tight junctions/desmosomes, and dislocation of cytoskeleton microfilaments. Since the cadherin / catenin complexes are further associated with the major cytoskeleton components at cell-cell junctions, we measured E-cadherin expression in drug-resistant cells. Both Western blot and immunocytochemical staining demonstrated the loss of E-cadherin expression in MCF-7 / Adr cells. Further, RNA in situ hybridization results confirmed that loss of E-cadherin expression occurred at the transcriptional level. CONCLUSIONS The drug-resistant MCF-7/Adr cells were found to be more invasive/metastatic than their parental control, possibly related to the loss of E-cadherin expression.

Abstract
Surface size, geometry and texture are some of the most influential subjects in the fields of precision and ultra-precision engineering, defining the functional interface through which emerging products operate. Next-generation products demand super-smooth surfaces, freeform geometries or even deterministically introduced microstructures to provide functional performance. Technological progress using these surfaces types is possible only if the associated manufacturing processes are rigorously controlled and the surfaces are measurable. Metrology for advanced surfaces is not established. The current state of the art is challenged in respect to (i) surface characteristics, extremity of size, ultra precision, quality, geometric complexity, or combinations of these aspects, and (ii) measurement technology for the manufacturing environment, in particular, online, non-contact, high speed, ease of use, small footprint and robustness. This study addresses the challenges in this subject area and discusses some fundaments and principles derived from interdisciplinary research. The combination of these aspects is enabling the creation of manufacturing-environment-based measurement technology. This is expected to facilitate advanced surface manufacture over a wide range of sectors, including large science programmes and high-technology engineering.

This article is a summary of the Satellite Meeting, which followed on from the Discussion Meeting at the Royal Society on 'Ultra-precision engineering: from physics to manufacture', held at the Kavli Royal Society International Centre, Chicheley Hall, Buckinghamshire, UK. The meeting was restricted to 18 invited experts in various aspects of precision metrology from academics from the UK and Sweden, Government Institutes from the UK and Germany and global aerospace industries. It examined and identified metrology problem areas that are, or may be, limiting future developments in precision engineering and, in particular, metrology. The Satellite Meeting was intended to produce a vision that will inspire academia and industry to address the solutions of those open-ended problems identified. The discussion covered three areas, namely the function of engineering parts, their measurement and their manufacture, as well as their interactions.

Abstract
BACKGROUND MOR1 is the main transcript of μ-opioid receptor (MOR) gene, which represents a mandatory molecule for the analgesic effects of opioids and plays an important role in the pathology of inflammatory pain. MicroRNAs (miR) are non-coding molecules that primarily modulate gene expression at the post-transcriptional level in various pathophysiological conditions. Based on in silico analysis, an exact match to the seed sequence of miR-134 was found in 3'-untranslated region of MOR1. Given the important roles of MOR1 in pain modulation, the purpose of this study is to investigate whether miR-134 can regulate the MOR1 following allodynia. METHODS Using Freund's adjuvant (CFA)-induced chronic inflammatory pain model, we investigated the expression profiles of miR-134 and MOR1 in rat dorsal root ganglia (DRG) using quantitative real-time polymerase chain reaction, in situ hybridization and immunohistochemistry, respectively. The relationship of miR-134 and MOR1 expressions was analysed by linear regression. Luciferase assay was used to examine whether MOR1 was the target of miR-134. RESULTS Our results showed that miR-134 expression level was inversely related to MOR1 expression. Down-regulation of miR-134 and up-regulation of MOR1 in the same tissues after inflammatory pain were observed. Functional experiments showed that MOR1 expression in SH-SY5Y cells was up-regulated after inhibition of miR-134, indicating that MOR1 was a target of miR-134. CONCLUSIONS Our present data suggested a model that miR-134 participated in CFA-induced inflammatory pain by balancing the expression of MOR1 in DRGs, which implied that miR-134 may be a potential therapeutic target for the treatment of neuropathic pain including inflammation.

Abstract
OBJECTIVE: This study investigated the potential synergistic effects of two inducers of apoptosis: the small molecule ABT-737 and arsenic trioxide (ATO). METHODS: Human gastric carcinoma cell lines SGC-7901 and MGC-803 were used to determine the effects of ABT-737 and ATO (alone or in combination) on cell proliferation and apoptosis in vitro. In vivo effects of these drugs were investigated in SGC-7901 solid tumours, grown in immunodeficient mice. RESULTS: ABT-737 and ATO inhibited proliferation and induced apoptosis in SGC-7901 and MGC-803 cells in concentration- and time-dependent manners, and showed a synergistic effect. ABT-737 disturbed the binding of B cell lymphoma (Bcl)-2 homologous antagonist killer and Bcl-extra large; ATO downregulated myeloid cell leukaemia (Mcl)-1 protein and upregulated Mcl-1short, the short splicing variant. ABT-737 and ATO significantly suppressed SGC-7901 xenograft growth, synergistically inhibited tumour growth and induced apoptosis in vivo. CONCLUSIONS: This study provides preclinical evidence that ABT-737 and ATO synergize to induce apoptosis of gastric carcinoma cells, suggesting that further investigation of these agents (as potential treatments for gastric cancer) is warranted.

Abstract
OBJECTIVE An RU486-inducible recombinant adenovirus-Nrf2 construct (Ad-RUNrf2) was constructed and expressed in H460 cells to determine whether Nrf2 gene expression can be regulated and to observe the effect of the adenovirus Ad-RUNrf2 on inflammatory cytokines, oxidative stress and apoptotic factors that mediate paraquat (PQ)-induced A549 cell injury. METHODS The Nrf2 gene within the RU486 (mifepristone)-inducible system was introduced into an adenovirus vector. A549 cells were transfected with Ad-RUNrf2, and Nrf2 expression was detected using Western blotting and real time-polymerase chain reaction (RT-PCR). RT-PCR, Western blots and enzyme-linked immunosorbent assay were used for observing the effect of RU486-induced Nrf2 expression on the inflammatory cytokines (interleukin-6 (IL-6), IL-10 and tumor necrosis factor-α (TNF-α)), oxidative stress factors (catalase (CAT) and malondialdehyde (MDA)) and apoptosis factors (caspase-3, caspase-9 and cytochrome C) that mediated PQ-induced A549 cell injury. RESULTS After infection of H460 cells by Ad-RUNrf2, RT-PCR and Western blot analyses showed that Nrf2 expression increased with additional RU486 doses. IL-6 and TNF-α protein and gene expression levels were significantly reduced, and IL-10 protein levels were significantly increased. Although IL-10 expression increased, it remained significantly lower than that of noninduced adenovirus infection and the simple virus exposure group. RU486 induced a significant reduction in MDA expression and increased CAT protein levels. Caspase-9 and caspase-3 protein and gene expression levels decreased in the RU486 induction group (p < 0.05). Cytochrome C protein levels were not significantly reduced, but its gene expression was significantly decreased (p < 0.05). CONCLUSION Ad-RUNrf2 adenovirus was successfully constructed and can be stably expressed and regulated in cells. Ad-RUNrf2 can reduce PQ-induced inflammation, oxidative stress and apoptosis in A549 cells.

Abstract
Background: The inflammation-based Glasgow prognostic score (GPS) has been shown to be a prognostic factor for a variety of tumours. This study investigates the significance of the modified GPS (mGPS) for the prognosis of patients with gastric cancer. Methods: The mGPS (0=C-reactive protein (CRP)⩽10 mg l−1, 1=CRP>10 mg l−1 and 2=CRP>10 mg l−1 and albumin<35 g l−1) was calculated on the basis of preoperative data for 1710 patients with gastric cancer who underwent surgery between January 2000 and December 2007. Patients were given an mGPS of 0, 1 or 2. The prognostic significance was analysed by univariate and multivariate analyses. Results: Increased mGPS was associated with male patient, old age, low body mass index, increased white cell count and neutrophils, elevated carcinoembryonic antigen and CA19-9 and advanced tumour stage. Kaplan–Meier analysis and log-rank test revealed that a higher mGPS predicted a higher risk of postoperative mortality in both relative early-stage (stage I; P<0.001) and advanced-stage cancer (stage II, III and IV; P<0.001). Multivariate analysis demonstrated the mGPS to be a risk factor for postoperative mortality (odds ratio 1.845; 95% confidence interval 1.184–2.875; P=0.007). Conclusion: The preoperative mGPS is a simple and useful prognostic factor for postoperative survival in patients with gastric cancer.
