| 1 | Tailoring strength-ductility balance of caliber-rolled AZ31 Mg alloy through subsequent annealing显示文摘Recently,multi-pass caliber rolling has been shown to be effective for Mg alloys.This study investigated the effect of subsequent annealing on the mechanical properties of a caliber-rolled AZ31 Mg alloy to modulate the strength-ductility relationship.This annealing gave rise to different trends in mechanical properties depending on the temperature regime.Low-temperature annealing(T≤473 K)exhibited a typical trade-off relationship,where an increase in annealing temperature resulted in increased ductility but decreased strength and hardness.Such a heat treatment did not degrade the high strength-ductility balance of the caliber-rolled alloy,suggesting that the mechanical properties could be tailored for different potential applications.In contrast,high-temperature annealing(T>473 K)caused a simultaneous deterioration in strength,hardness,and ductility with increasing annealing temperature.These differences are discussed in terms of the varying microstructural features under the different investigated annealing regimes. | Taein Kong Byung Je Kwak Jonghyun Kim Jeong Hun Lee Sung Hyuk Park Ji Hoon Kim Young Hoon Moon Hyun Sik Yoon Taekyung Lee | 2020 | Journal of Magnesium and Alloys2020，8，1： | 10 |
| 2 | Clinical significance and usefulness of soluble heparin binding-epidermal growth factor in gastric cancer显示文摘AIM:To evaluate the clinical usefulness of solubleheparin-binding epidermal growth factor(s HB-EGF)as a serum biomarker for gastric cancer(GC).METHODS:Serum s HB-EGF levels were measured by a commercially available human HB-EGF ELISA Kit and compared among 60 normal controls,30 highrisk patients,37 early gastric cancer(EGC),and30 advanced gastric cancer(AGC)through ANOVA test.Correlations between serum s HB-EGF and clinicopathological features of GC were analyzed through Spearman’s correlation.The diagnostic performance of serum s HB-EGF for GC was evaluated through receiver operating characteristic(ROC)curve and logistic regression analysis.RESULTS:Serum s HB-EGF levels were significantly higher in AGC group(314.4±127.5 pg/m L)than EGC(165.3±123.2 pg/m L),high-risk(98.7±67.3 pg/m L),and control(94.7±83.6 pg/m L)groups(post-hoc Bonferroni,all P<0.001),respectively.Serum s HB-EGF levels were also significantly higher in EGC group than high-risk(P=0.049)and control(P=0.006)groups.Clinicopathologically,serum s HB-EGF levels closely correlated with depth of invasion(T-stage,γs=0.669,P<0.001),lymph node metastasis(N-stage,γs=0.407,P=0.001),and distant metastasis(M-stage,γs=0.261,P=0.030).ROC curve and logistic regression analysis demonstrated a remarkable diagnostic potential of serum s HB-EGF.CONCLUSION:Serum s HB-EGF is closely correlated with advanced stage GC and can be a promising serological biomarker for GC. | Hye Won Chung Hoon Young Kong Jong-Baeck Lim | 2015 | World Journal of Gastroenterology2015，21，7： | 4 |
