Role of retained austenite in low alloy steel at low temperature monitored by neutron diffraction
In-situ neutron diffraction measurements during tensile tests at low temperatures of a low alloy steel containing retained austenite (γ) have been performed. Evolutions of phase fractions and phase stresses were analyzed and discussed with the progress of deformation. The role of γ in the steel during deformation at low temperatures was observed not to directly in the contribution to the strengths but in the improvement of the elongation by transformation of γ to martensite -and in the increasing of the work-hardening rate by an increase in the phase fraction of martensite and the work hardening of martensite.journal articl
Correlation between anti EPC abs, laboratory results and biomarkers.
<p>Correlation between anti EPC abs, laboratory results and biomarkers.</p
Association of anti-EPC abs with circulating EPC and with VCAM-1 expression on HUVEC and EPC.
<p>Serum anti-EPC levels were correlated with circulating CD34+KDR+EPC (A) and with surface expression of the adhesion molecule VCAM-1 on HUVEC (B) and late outgrowth EPC (C).</p
Baseline characteristics of the study population.
<p>DM-Diabetes mellitus, HTN-Hypertension, HG-Hemoglobin, WBC-White blood cells, TG-triglyceride, HDL-high density lipoprotein, LDL-low density lipoprotein.</p
Analysis of late outgrowth EPC and binding characteristics of circulating anti-EPC antibodies.
<p>Late outgrowth EPC were obtained from several healthy individuals as described in methods. FACS was used test for surface marker expression (Left panel). To determine if antibodies to EPC are identical to AECA we performed competitive inhibition studies where anti-EPC or AECA were preincubated with EPC or AECA at different ratios and their binding to sold phase bound EPC or HUVEC tested by ELISA as described in methods (Right panel).</p
Association between anti-EPC levels and risk factors for atherosclerotic vascular disease.
<p>Levels of anti-EPC abs were determined by cyto ELISA as described in methods. The levels were correlated with the presence of individual risk factors (Age, gender, presence of hypertension and diabetes mellitus) and cumulative Framingham score.</p
