| 1 | 烧结后热处理对烧结硬化粉末冶金钢零件尺寸精度与力学性能的影响显示文摘在铁基粉末冶金零件的最终形生产中尺寸精度是一个关键参数。粉末冶金零件生产厂商一直在追求较大的零件,但终端用户规定的绝对公差一般并不随零件尺寸而改变。因此,对较大的零件,尺寸变化或尺寸变化的偏差必须减小。除了与常用低合金粉末冶金钢的压制与烧结相关的尺寸变化外,烧结硬化合金对粉末冶金零件生产还提出了一些独特挑战与机遇。在烧结炉中能淬硬的零件,就不要后续淬火作业了。可是,形成的未回火的马氏体显微结构对尺寸稳定性与力学性能来说并不理想。回火的淬硬钢由于马氏体转变成了密度较高的较稳定的铁素体与碳化物显微结构,从而改善了力学性能并使尺寸产生收缩。另外,许多铜及碳含量高的烧结硬化钢牌号都会导致残留奥氏体的含量较高。残留奥氏体可改进冲击性能与延展性,但是,由于热波动残余奥氏体可转变成密度较低的贝氏体和/或马氏体从而影响尺寸的稳定性。为得到最好的力学性能与尺寸控制组合,烧结硬化钢需要进行适当的热处理。本文考察不同的烧结后热处理对烧结硬化粉末冶金钢尺寸、显微结构以及力学性能的影响。 | Bruce Lindsley Thomas Murphy 亓家钟(译) 韩风麟(校) | 2011 | 粉末冶金工业2011，21，1： | 5 |

| 3 | Diagnostic accuracy of tests for Helicobacter pylori in an Alaska Native population显示文摘AIM:To evaluate the accuracy of two non-invasivetests in a population of Alaska Native persons. Highrates of Helico bacter pylori(H. pylori) infection,H. pylori treatment failure,and gastric cancer in this population necessitate documentation of infection status atmultiple time points over a patient's life.METHODS:In 280 patients undergoing endoscopy,H. pylori was diagnosed by culture,histology,rapidurease test,13C urea breath test(UBT) ,and immuno-globulin G antibodies to H. pylori in serum. The performances of 13C-UBT and antibody test were compared to a gold standard defined by a positive H. pylori testby culture or,in case of a negative culture result,bypositive histology and a positive rapid urease test.RESULTS:The sensitivity and specificity of the 13C-UBT were 93% and 88%,respectively,relative to thegold standard. The antibody test had an equivalents ensitivity of 93% with a reduced specificity of 68%.The false positive results for the antibody test were as-sociated with previous treatment for an H. pylori infection [relative risk(RR) = 2.8]. High levels of antibodiesto H. pylori were associated with chronic gastritis and male gender,while high scores in the 13C-UBT testwere associated with older age and with the H. pyloribacteria load on histological examination(RR = 4.4) .CONCLUSION:The 13C-UBT out performed the anti-body test for H. pylori and could be used when a non-invasive test is clinically necessary to document treatment out come or when monitoring for reinfection. | Dana L Bruden Michael G Bruce Karen M Miernyk Julie Morris Debby Hurlburt Thomas W Hennessy Helen Peters Frank Sacco Alan J Parkinson Brian J McMahon | 2011 | World Journal of Gastroenterology2011，17，42： | 3 |
| 4 | 烧结-硬化钢的尺寸精度显示文摘尺寸精度是铁基粉末冶金零件生产工艺的关键参数。除了和标准粉末冶金低合金钢的压制与烧结相关的尺寸变化外,烧结-硬化合金还会产生从奥氏体转变为马氏体的相变。马氏体是钢中密度最低的相,因此,冷却时马氏体的形成会导致零件显著胀大。当马氏体转变为密度较高的铁素体与碳化物显微组织时,回火的淬硬钢发生收缩。这两种相变对零件的尺寸变化都有很大影响。另外,在Cu与C含量高的马氏体区可能有大量残余奥氏体存在。奥氏体相密度最高,所以残余奥氏体会导致压坯胀大较小。除回火处理外,马氏体与残余奥氏体的存在都会影响零件的最终尺寸。本文考察了两个烧结-硬化钢牌号,同时通过不同的后烧结热处理,研究了这两个牌号钢的尺寸变化和显微组织变化。 | Bruce Lindsley Thomas Murphy | 2009 | 粉末冶金技术2009，27，6： | 2 |

| 8 | The effects of Spirulina on anemia and immune function in senior citizens显示文摘Anemia and immunological dysfunction(i.e.immunosenescence)are commonly found in older subjects and nutritional approaches are sought to counteract these phenomena.Spirulina is a filamentous and multicellular bule-green alga capable of reducing inflammation and also manifesting antioxidant effects.We hypothesized that Spirulina may ameliorate anemia and immunosenescence in senior citizens with a history of anemia.We enrolled 40 volunteers of both sexes with an age of 50 years or older who had no history of major chronic diseases.Participants took a Spirulina supplementation for 12 weeks and were administered comprehensive dietary questionnaires to determine their nutritional regimen during the study.Complete cell count(CCC)and indoleamine 2,3-dioxygenase(IDO)enzyme activity,as a sign of immune function,were determined at baseline and weeks 6 and 12 of supplementation.Thirty study participants completed the entire study and the data obtained were analyzed.Over the 12-week study period,there was a steady increase in average values of mean corpuscular hemoglobin in subjects of both sexes.In addition,mean corpuscular volume and mean corpuscular hemoglobin concentration also increased in male participants.Older women appeared to benefit more rapidly from Spirulina supplements.Similarly,the majority of subjects manifested increased IDO activity and white blood cell count at 6 and 12 weeks of Spirulina supplementation.Spirulina may ameliorate anemia and immunosenescence in older subjects.We encourage large human studies to determine whether this safe supplement could prove beneficial in randomized clinical trials. | Carlo Selmi Patrick SC Leung Laura Fischer Bruce German Chen-Yen Yang Thomas P Kenny Gerry R Cysewski M Eric Gershwin | 2011 | Cellular & Molecular Immunology2011，8，3： | 2 |

| 14 | Laser patterning for the study of MSC cardiogenic differentiation at the single-cell level显示文摘Mesenchymal stem cells(MSCs)have been cited as contributors to heart repair through cardiogenic differentiation and multiple cellular interactions,including the paracrine effect,cell fusion,and mechanical and electrical couplings.Due to heart–muscle complexity,progress in the development of knowledge concerning the role of MSCs in cardiac repair is heavily based on MSC–cardiomyocyte coculture.In conventional coculture systems,however,the in vivo cardiac muscle structure,in which rod-shaped cells are connected end-to-end,is not sustained;instead,irregularly shaped cells spread randomly,resulting in randomly distributed cell junctions.Consequently,contact-mediated cell–cell interactions(e.g.,the electrical triggering signal and the mechanical contraction wave that propagate through MSC–cardiomyocyte junctions)occur randomly.Thus,the data generated on the beneficial effects of MSCs may be irrelevant to in vivo biological processes.In this study,we explored whether cardiomyocyte alignment,the most important phenotype,is relevant to stem cell cardiogenic differentiation.Here,we report(i)the construction of a laser-patterned,biochip-based,stem cell–cardiomyocyte coculture model with controlled cell alignment;and(ii)single-cell-level data on stem cell cardiogenic differentiation under in vivo-like cardiomyocyte alignment conditions. | Zhen Ma Qiuying Liu Huaxiao Yang Raymond B Runyan Carol A Eisenberg Meifeng Xu Thomas K Borg Roger Markwald Yifei Wang Bruce Z Gao | 2013 | Light(Science & Applications)2013，2，1： | 2 |
