| 2 | Effect of Powder Particle Shape on the Properties of In Situ Ti–TiB Composite Materials Produced by Selective Laser Melting显示文摘This work studied the preparation of starting powder mixture influenced by milling time and its effect on the particle morphology(especially the shape) and, consequently, density and compression properties of in situ Ti–Ti B composite materials produced by selective laser melting(SLM) technology. Starting powder composite system was prepared by mixing 95 wt% commercially pure titanium(CP-Ti) and 5wt% titanium diboride(TiB 2) powders and subsequently milled for two different times(i.e. 2 h and 4 h).The milled powder mixtures after 2 h and 4 h show nearly spherical and irregular shape, respectively.Subsequently, the resultant Ti–5 wt% TiB 2 powder mixtures were used for SLM processing. Scanning electron microscopy image of the SLM-processed Ti–Ti B composite samples show needle-shape TiB phase distributed across the Ti matrix, which is the product of an in-situ chemical reaction between Ti and TiB 2during SLM. The Ti–Ti B composite samples prepared from 2 h and 4 h milled Ti–TiB 2 powders show different relative densities of 99.5% and 95.1%, respectively. Also, the compression properties such as ultimate strength and compression strain for the 99.5% dense composite samples is 1421 MPa and 17.8%, respectively, which are superior to those(883 MPa and 5.5%, respectively) for the 95.1% dense sample. The results indicate that once Ti and TiB 2 powders are connected firmly to each other and powder mixture of nearly spherical shape is obtained, there is no additional benefit in increasing the milling time and, instead, it has a negative effect on the density(i.e. increasing porosity level) of the Ti–Ti B composite materials and their mechanical properties. | Hooyar Attar Konda G.Prashanth Lai-Chang Zhang Mariana Calin Ilya V.Okulov Sergio Scudino Chao Yang Jürgen Eckert | 2015 | Journal of Materials Science & Technology2015，31，10： | 12 |
| 3 | Resveratrol engages selective apoptotic signals in gastric adenocarcinoma cells显示文摘AIM: To investigate the intracellular apoptotic signals engaged by resveratrol in three gastric adenocarcinoma cancer cell lines, two of which (AGS and SNU-1) express p53 and one (KATO-Ⅲ) with deleted p53. METHODS: Nuclear fragmentation was used to quanti- tate apoptotic cells; caspase activity was determined by photometric detection of cleaved substrates; formation of oxidized cytochrome C was used to measure cytochrome C activity, and Western blot analysis was used to determine protein expression. RESULTS: Gastric cancer cells, irrespective of their p53 status, responded to resveratrol with fragmentation of DNA and cleavage of nuclear lamins A and B and PARP. Resveratrol, however, has no effect on mitochondria-associated apoptotic proteins Bcl-2, Bcl- xl, Bax, Bid or Smac/Diablo, and did not promote sub- cellular redistribution of cytochrome C, indicating that resveratrol-induced apoptosis of gastric carcinoma cells does not require breakdown of mitochondrial membrane integrity. Resveratrol up-regulated p53 protein in SNU-1 and AGS cells but there was a difference in response of intracellular apoptotic signals between these cell lines. SNU-1 cells responded to resveratrol treatment with down-regulation of survivin, whereas in AGS and KATO- Ⅲ cells resveratrol stimulated caspase 3 and cytochrome C oxidase activities. CONCLUSION: These findings indicate that even within a specific cancer the intracellular apoptotic signals engaged by resveratrol are cell type dependent and suggest that such differences may be related to differentiation or lack of differentiation of these cells. | William L Riles Jason Erickson Sanjay Nayyar Mary Jo Atten Bashar M Attar Oksana Holian | 2006 | World Journal of Gastroenterology2006，12，35： | 8 |
| 4 | Procalcitonin,and cytokines document a dynamic inflammatory state in non-infected cirrhotic patients with ascites显示文摘AIM:To quantitate the simultaneous serum and ascitic fluid levels of procalcitonin and inflammatory markers in cirrhotics with and without ascites.METHODS:A total of 88 consecutive severe cirrhotic patients seen in a large city hospital liver clinic were studied and divided into two groups,those with and without ascites.Group 1 consisted of 41 cirrhotic patients with massive ascites,as demonstrated by necessity for therapeutic large-volume paracentesis.Group 2consisted of 47 cirrhotic patients without any clinically documented ascites to include either a recent abdominal computed tomography scan or ultrasound study.Serum and ascitic fluid levels of an array of inflammatory markers,including procalcitonin,were measured and compared to each other and a normal plasma panel(NPP).RESULTS:The values for inflammatory markers assayed in the serum of Groups 1 and 2,and ascitic fluid of the Group 1.The plasma levels of the inflammatory cytokines interleukin(IL)-2,IL-4,IL-6,IL-8,interferon gamma(IFNγ)and epidermal growth factor(EGF)were all significantly greater in the serum of Group 1as compared to that of the serum obtained from the Group 2 subjects(all P<0.05).There were significantly greater serum levels of IL-6,IL-8,IL-10,monocyte chemoattractant protein-1,tumor necrosis factor-α,vascular endothelial growth factor and EGF when comparing Group 2 to the NPP.There was no significant difference for IL-1A,IL-1B,IL-2,IL-4 and IFNγlevels between these two groups.Serum procalcitonin levels were increased in cirrhotics with ascites compared to cirrhotics without ascites,but serum levels were similar to ascites levels within the ascites group.Furthermore,many of these cytokines,but not procalcitonin,demonstrate an ascites-to-serum gradient.Serum procalcitonin does not demonstrate any significant difference segregated by liver etiology in the ascites group;but ascitic fluid procalcitonin is elevated significantly in car-diac cirrhosis/miscellaneous subgroup compared to the hepatitis C virus and alcoholic cirrhosis subgroups.CONCLUSION:Procalcitonin in the ascitic fluid,but not in the serum,differentiates between cirrhotic subgroup reflecting the dynamic interplay of ascites,bacterial translocation and the peri-peritoneal cytokine. | Bashar M Attar Christopher M Moore Magdalena George Nicolae Ion-Nedelcu Rafael Turbay Annamma Zachariah Guiliano Ramadori Jawed Fareed David H Van Thiel | 2014 | World Journal of Gastroenterology2014，20，9： | 4 |
| 5 | Fabrication and Growth Mechanism of Single-crystalline Rutile TiO_2 Nanowires by Liquid-phase Deposition Process in a Porous Alumina Template显示文摘TiO_2 nanowire arrays were successfully fabricated by liquid-phase deposition method using porous alumina templates.The obtained TiO_2 nanowires were characterized using Raman spectroscopy,X-ray diffraction(XRD),scanning electron microscopy(SEM),field emission scanning electron microscopy(FESEM),transmission electron microscopy(TEM),and selected area electron diffraction(SAED)analysis.Results of electron microscopic observations indicated that the nanowires were smooth and uniform with a diameter of about 50-80 nm and several micrometers in length.SAED,Raman,and XRD measurements showed that TiO_2 nanowires were single-crystalline with a pure rutile structure after heating at 800 ℃ for 10 h.In this situation,the nanowire constituents grew preferentially along the <001>direction.Furthermore,the formation process and mechanistic study of the TiO_2 nanowire arrays were proposed and discussed in detail.The nanowires are clearly produced by the deposition of TiO_2 particles on the inner wall of the template nanochannels. | Abbas Sadeghzadeh Attar Zahra Hassani | 2015 | Journal of Materials Science & Technology2015，31，8： | 4 |
| 6 | Corrosion of Alloy Steel in 30% Ethylene Glycol Solution and CrO_4^(2-) Under Hydrodynamic Condition显示文摘The electrochemical behavior of steel alloy in 30%ethylene glycol-water solution at different solution rotating speeds was investigated by polarization curves and AC impedance measurements.The results obtained showed that corrosion rate did not change significantly at different rotating speeds.The effect of chromate as the inhibitor was studied and high inhibition efficiency was obtained.It was found that surface passivation occurred in the presence of the inhibitor.The inhibiting effect of the chromate was explained on the basis of the competitive adsorption between the inorganic anions and the aggressive Cl-and the adsorption isotherm basically obeys the Langmuir adsorption isotherm.Thermodynamic parameters for inhibitor adsorption were determined and results reveal that the adsorption process is spontaneous. | M Niknejad Khomami I Danaee A A Attar M Peykari | 2013 | Journal of Iron and Steel Research(International)2013，20，6： | 3 |
| 7 | Disease dependent qualitative and quantitative differences in the inflammatory response to ascites occurring in cirrhotics显示文摘AIM:To assess differing patterns and levels of ascitic fluid cyctokine and growth factors exist between those with a high risk and low risk of spontaneous bacterial peritonitis(SBP). METHODS: A total of 57 consecutive patients with ascites requiring a large volume paracentesis were studied. Their age, gender, specific underlying disease conditions were recorded after a review of their clinical records. Each underwent a routine assessment prior to their paracentesis consisting of a complete blood count, complete metabolic profile and prothrombin time/international normalized ratio(INR) determination. The ascitic fluid was cultured and a complete cellcount and albumin determination was obtained on the fluid. In addition, blood and ascitic fluid was assessed for the levels of interleukin interleukin(IL)-1A, IL-1B, IL-2, IL-4, IL-8, IL-10, monocyte chemotactic protein(MCP)-1, tumor necrosis factor(TNF)-α, interferon(IFN)-γ, vascular endothelial growth factor(VEGF) and epidermal growth factor(EGF) utilizing the Randox Biochip platforms(Boston, MA). A serum-ascites gradient, for each cytokine and growth factor was calculated. The results are reported as mean ± SEM between disease groups with statistical analysis consisting of the student t-test(two tailed) with a P value of 0.05 defining significance. RESULTS: No clinically important demographic or biochemical differences between the 4 groups studied were evident. In contrast, marked difference in the cytokine and growth factors levels and pattern were evident between the 4 disease groups. Individuals with alcoholic cirrhosis had the highest levels of IL-1A, IL-1B, IL-4, IFNγ. Those with malignant disease had the highest levels of IL-2. Those with hepatitis C virus(HCV) associated cirrhosis had the highest value for IL-6, IL-8, IL-10, MCP-1 and VEGF. Those with cardiac disease had the highest level of TNF-α and EGF. The calculated serum- ascites gradients for the cardiac and malignant disease groups had a greater frequency of negative values signifying greater levels of IL-8, IL-10 and MCP-1 in ascites than did those with alcohol or HCV disease. CONCLUSION: These data document important differences in the cytokine and growth factor levels in plasma, ascitic fluid and the calculated plasma- ascites fluid gradients in cirrhotics requiring a large volume paracentesis. These differences may be important in determining the risk for bacterial peritonitis. | Bashar M Attar Magdalena George Nicolae Ion-Nedelcu Guilliano Ramadori David H Van Thiel | 2014 | World Journal of Hepatology2014，6，2： | 3 |
