Abstract
BACKGROUND Cyclooxygenase-2 (COX-2) is involved in oesophageal carcinogenesis, but the clinical and prognostic significance of COX-2 expression in oesophageal squamous cell carcinoma (ESCC) remains controversial. AIM To evaluate the clinicopathological and prognostic role of COX-2 expression in ESCC. METHODS Studies assessing clinical or prognostic significance of COX-2 expression in ESCC published until December 2008 were selected. A meta-analysis was performed to clarify the impact of COX-2 expression on clinicopathological parameters or overall survival (OS) in ESCC. RESULTS A total of 19 studies met the inclusion criteria, among which 17 studies were about the clinicopathological significance of COX-2 expression in ESCC, 12 studies were dealing with prognostic role of COX-2 expression in ESCC and 10 studies evaluated both of them. Overexpression of COX-2 was significantly correlated with not only the depth of invasion and TNM stage, with a combined odds ratio (OR) of 0.55 (95%CI: 0.34-0.90, Z = 2.41, P = 0.02) and 0.55 (95%CI: 0.32-0.95, Z = 2.13, P = 0.03) respectively but also the reduced OS with relative risk (RR) 1.42, 95% CI: 1.07-1.90, Z = 2.43, P = 0.02). CONCLUSIONS COX-2 might play an important role in the progress of ESCC, overexpression of COX-2 correlates with not only the depth of invasion and TNM stage but also the reduced OS. COX-2 might be a potential therapy target for ESCC and work as a prognostic factor for ESCC patients, yet the clinicopathological and prognostic role of COX-2 in ESCC still needs further confirmation by well-designed prospective studies.

Abstract
We report K/pi fluctuations from Au + Au collisions at sqrt[s(NN)]= 19.6, 62.4, 130, and 200 GeV using the STAR detector at the Relativistic Heavy Ion Collider. K/pi fluctuations in central collisions show little dependence on incident energy and are on the same order as those from NA49 at the Super Proton Synchrotron in central Pb + Pb collisions at sqrt[s(NN)]=12.3 and 17.3 GeV. We report results for the collision centrality dependence of K/pi fluctuations and results for charge-separated fluctuations. We observe that the K/pi fluctuations scale with the charged particle multiplicity density.

Abstract
A novel multichannel Doppler backscattering system has been designed and tested for application on the DIII-D [J. L. Luxon, Fusion Sci. Technol. 48, 828 (2005)] and National Spherical Torus Experiment (NSTX) [M. Ono et al., Nucl. Fusion 40, 557 (2000)] fusion plasma devices. Doppler backscattering measures localized intermediate wavenumber (k(perpendicular)rho(i) approximately 1-4,k(perpendicular) approximately 2-15 cm(-1)) density fluctuations and the propagation velocity of turbulent structures. Microwave radiation is launched at a frequency that approaches a cutoff layer in the plasma and at an angle that is oblique to the cutoff layer. Bragg backscattering occurs near the cutoff layer for fluctuations with k(perpendicular) approximately -2k(i), where k(i) is the incident probe wave vector at the scattering location. The turbulence propagation velocity can be determined from the Doppler shift in the return signal together with knowledge of the scattering wavenumber. Ray tracing simulations are used to determine k(perpendicular) and the scattering location. Frequency modulation of a voltage-controlled solid state microwave source followed by frequency multiplication is used to create an array of finely spaced (Delta f=350 MHz) frequencies spanning 1.4 GHz. The center of the array bandwidth is tunable within the range of approximately 53-78 GHz. This article details the system design, laboratory tests, and presents initial data from DIII-D plasmas.

Abstract
Myocardial ischemic preconditioning up-regulated protein 1 (Mipu1), a novel zinc finger protein, was originally cloned using bioinformatic analysis and 5' RACE technology of rat heart after a transient myocardial ischemia/reperfusion procedure in our laboratory. In order to investigate the functions of Mipu1, the recombinant prokaryotic expression vector pQE31-Mipu1 was constructed and transformed into Escherichia coli M15(pREP4), and Mipu1-6His fusion protein was expressed and purified. The identity of the purified protein was confirmed by mass spectrometry. The molecular mass of the Mipu1 protein was 70.03779 kDa. The fusion protein was intracutaneously injected to immunize New Zealand rabbits to produce a polyclonal antibody. The antibody titer was approximately 1:16,000. The antibody was tested by Western blotting for specificity and sensitivity. Using the antibody, it was found that Mipu1 was highly expressed in the heart and brain of rats and was localized in the nucleus of H9c2 myogenic cells. The present study lays the foundation for further study of the biological functions of Mipu1.

Abstract
In this work, plasma-sprayed nanostructured zirconia coatings stabilized with 3mol.% yttria (3Y-TZP) were deposited on Ti substrates. The microstructure and phase composition of coatings were characterized using scanning electron microscopy and X-ray diffraction. The in vitro bioactivity of coatings was evaluated by examining the formation of bone-like apatite on its surface in simulated body fluid. MG63 cell lines were cultured on the coating to investigate its cytocompatibility. The crystalline phase of the as-sprayed coating was tetragonal zirconia, and no monoclinic zirconia was detected. The size of the grains on the as-sprayed coating surface was less than 100nm. The apatite could precipitate on the surface of the coating immersed in simulated body fluid for 28days while no apatite was formed on the surface of 3Y-TZP ceramic control, indicating that the bioactivity of the coating is superior to the ceramic with the same composition. It also revealed that the polished coating whose nanostructural outmost layer was removed was bioinert, implying the significance of the nanosized grains for its bioactivity. MG63 cells could adhere, grow and proliferate well on the coating surface, indicating that the coating had good cytocompatibility. Phase stability of plasma-sprayed 3Y-TZP coating was evaluated under hydrothermal conditions at 134 degrees C. It revealed that the plasma-sprayed nanostructured zirconia coating was more sensitive to aging than that of zirconia ceramics.

Abstract
AIMS Reports from non-Asian populations indicate that painful physical symptoms (PPS) are associated with poorer clinical and functional outcomes in major depressive disorder (MDD). The purpose of this study is to report comparative changes in disease severity, treatment patterns and quality of life observed in East Asian patients with MDD, with and without PPS, as assessed prospectively over a 3-month observation period. METHODS This observational study enrolled 909 patients with MDD in psychiatric care settings in China, Hong Kong, Korea, Malaysia, Singapore and Taiwan. Patients were classified as PPS positive (PPS+) or negative (PPS-) based on mean modified Somatic Symptom Inventory scores of >or= 2 or < 2 respectively. The Clinical Global Impression of Severity (CGI-S) and 17-item Hamilton Depression Rating Scale (HAMD(17)) determined depression severity; a visual analogue scale (VAS) determined pain severity; and the EuroQoL (EQ-5D) assessed well-being after 3 months observation. RESULTS Of the 909 enrollees, 355/471 (75.4%) of PPS+ patients and 363/438 (82.9%) of PPS- patients completed the study (p = 0.006). PPS+ patients improved less than PPS- patients on depression, pain and quality of life measures during the study (HAMD(17) p < 0.001, CGI-S p < 0.001, VAS p = 0.008 and EQ-5D p = 0.004). Fewer PPS+ patients (46.5%) achieved remission compared with PPS- patients (69.4%, p < 0.001). CONCLUSION As the presence of PPS is associated with poorer outcomes in East Asian MDD patients, clinical management should aim to address both the mental and PPS associated with MDD.

Abstract
Recently, we generalized the Delta-Eddington phase function and applied it to the radiative transfer equation for modeling the photon propagation in biological tissue. The resultant phase approximation model was shown to be highly accurate with a wide range of optical properties, including the strongly absorbing and weakly scattering media. In this paper, we propose phase-approximation-based method for estimating the optical parameters. Specifically, we design an iterative algorithm to take advantage of both the global search ability of the differential evolution algorithm and the efficiency of the conjugate gradient method. Then, we demonstrate the feasibility and merits of the proposed method in both numerical simulation and phantom experiments.

Abstract
Elevated levels of protein kinase CK2 (formerly casein kinase 2 or II) have long been associated with increased cell growth and proliferation both in normal and cancer cells. The ability of CK2 to also act as a potent suppressor of apoptosis offers an important link to its involvement in cancer since deregulation of both cell proliferation and apoptosis are among the key features of cancer cell biology. Dysregulated CK2 may impact both of these processes in cancer cells. All cancers that have been examined show increased CK2 expression, which may also relate to prognosis. The extensive involvement of CK2 in cancer derives from its impact on diverse molecular pathways controlling cell proliferation and cell death. Downregulation of CK2 by various approaches results in induction of apoptosis in cultured cell and xenograft cancer models suggesting its potential as a therapeutic target.

Abstract
A highly aligned one-dimensional (1D) nanostructure was realized at the surface of Fe/ZnSe bilayers grown on GaAs(001) substrates through thermal annealing. These 1D nano-grooves were found to align along the [110] direction resulting in bent reflection high energy electron diffraction (RHEED) patterns when the sample was rotated relative to the e-beam. A model based on Ewald construction is presented to explain the unusual RHEED observation. The formation mechanism of this 1D nanostructure is possibly related to the minimization of surface energy, together with an Fe-Se exchange interaction and Fe-induced decomposition of several top ZnSe atomic layers during thermal annealing.

Abstract
e14591 Background: AT-101 is an orally active pan Bcl-2 inhibitor currently under clinical development in Phase II trials. We investigated the effect of AT-101 alone or in combination with chemotherapies or targeted kinase inhibitors in NSCLC both in vitro and in vivo. Methods: Growth inhibition was measured by WST assays. The CalculSyn method was used to assess drug interaction by calculating the Combination Index (CI) value. The ability of AT-101 to potentiate the anti-cancer effect of chemotherapies or kinase inhibitors was evaluated in xenograft models. Results: A panel of 11 NSCLC cell lines with overexpression of Bcl-2, Bcl- XL or Mcl-1 proteins was treated with AT-101, docetaxel, pemetrexed, erlotinib, sorafenib, sunitinib, rapamycin, as a single agent and in combination. AT-101 inhibited the growth with IC50 at 3–9 uM. When treating cells simultaneously with both agents, AT-101 demonstrated strong synergy with those agents in A549 or H460 cells with CI values < 1.0. Protein analysis results indicated that AT-101 caused apoptosis by a time- and dose-dependent induction of Noxa expression in those cells. The expression of Bcl- XL was not influenced by AT-101. Pro-Caspase-3 was reduced with increasing doses of AT-101. In vivo, combined treatment of AT-101 with docetaxel, erlotinib, or sorafenib synergistically suppressed subcutaneous NSCLC A549 cells tumor growth compared with treatment with either agent alone. The synergist effects with the ErbB1 inhibitor Erlotinib is associated with the overexpression of the target protein ErbB1 in those cells. Only combination therapy resulted in significant tumor growth delay and no significant toxicities were observed. Conclusions: Our results demonstrate that AT-101significantly enhances the anti-tumor activity of chemotherapy and targeted agents and may represent a promising new anticancer agent with a novel molecular mechanism. Molecular targeted therapy with AT-101 may improve the outcome of current chemotherapy for NSCLC with Bcl-2, Bcl-xL and/or Mcl-1 overexpression. [Table: see text]

Abstract
11034 Background: Skp2, a known oncogene, is overexpressed in several types of tumors and is associated with worse recurrence rate and overall survival in primary melanoma patients. Moreover, the anti-proliferative effects of Skp2 siRNA on various tumor cell lines have prompted the preclinical testing of Skp2 small molecule inhibitors. In this study, we assessed the clinical relevance and molecular mechanism(s) underlying Skp2 overexpression in metastatic melanoma patients. Methods: Skp2 protein levels were measured in 122 metastatic melanoma specimens using immunohistochemistry (IHC), and the association between Skp2 overexpression and post-recurrence survival was examined. Moreover, 22 cell lines (2 normal primary melanocytes, 2 primary immortal melanocytes, 4 primary melanoma cell lines, and 18 metastatic melanoma cell lines) were evaluated for Skp2 genomic amplification using Single Nucleotide Polymorphism (SNP) arrays (Affymetrix 6.0) and Skp2 gene expression using mRNA arrays (Affymetrix U133A 2.0) and quantitative RT-PCR. We also screened 18 cell lines for Skp2 mutation by sequencing. Results: Skp2 overexpression, defined as >25% tumor cells, was associated with shorter 3-yr post-recurrence survival (37%) compared to Skp2 expression ≤25% (55%) (HR=1.89, 95%, CI= 1.04, 3.42, p=0.04). Skp2 overexpression was significantly associated with the site of melanoma metastasis: visceral (n= 12; 89%), lymph node (n=49; 36%), brain (n=15; 14%), and soft-tissue (n=36; 6%) (p<0.001). SNP array revealed genomic amplification at the Skp2 locus in 6 (33%) metastatic cell lines and one primary melanoma cell line. Skp2 genomic amplification was associated with increased transcript expression. No Skp2 mutations were identified. Conclusions: Skp2 protein overexpression is associated with worse prognosis in metastasis in melanoma. Our results also support that gene amplification, rather than a Skp2 gene mutation, may be the major mechanism responsible for Skp2 aberrant expression in metastatic melanoma. No significant financial relationships to disclose.

Abstract
This work aims to explore the influence of the ionic products of dicalcium silicate coating on osteoblastic proliferation and differentiation, as well as on the expression of BMP2 and its signal transducers Smad1, 6 and 7 in MG-63 osteoblast-like cells. Plasma-sprayed dicalcium silicate coatings were soaked in DMEM to obtain culture media containing the ionic dissolution products of dicalcium silicate coating (Ca2SiO4-DMEM). MG63 osteoblast-like cells were cultured in Ca2SiO4-DMEM (experimental group) for 3-12 days, while those cultured in normal DMEM served as control (control group). MTT assay was used to evaluate cell viability and proliferation. Alkaline phosphatase activity (ALP), osteocalcin (OC) and type I collagen (COLI) were investigated as differentiation markers. Gene expression of BMP2 and Smad1, 6, 7 was also detected. BMP2 protein was examined by ELISA assay. Alizarin Red-S (AR-S) assay was used to detect mineralization. The results demonstrated that Si concentration in Ca2SiO4-DMEM is markedly higher than that in normal DMEM. Compared to the control group, MG63 cells of the experimental group exhibited upregulated proliferation on day 3, and markedly upregulated gene expression of the differentiation markers, especially on days 9 and 12 for OC and on days 3, 6 and 9 for ALP. Gene expression of BMP2 and Smad1, as well as BMP2 protein secreted into culture media, was also upregulated in the experimental group, while gene expression of Smad6 and 7 was not influenced. AR-S assay indicated a higher calcium mineral content deposition in cells of the experimental group. In conclusion, the ionic products of plasma-sprayed dicalcium silicate coating are beneficial to the proliferation and differentiation of MG63 osteoblast-like cells.

Abstract
We have developed a compact, computer-piloted, high sensitivity broadband imaging system for laboratory research that is compatible with various detectors. Mirror optics allow application from the visible to the far infrared spectral range. A prototype tested in conjunction with a mercury cadmium telluride detector exhibits a peak detectivity of 6.7x10(10) cm Hz(1/2)/W at a wavelength of 11.8 microm. Temperature and spatial resolutions of 0.06 K and 1.6 mrad, respectively, were demonstrated.
