Steel Design by Advanced Analysis: Material Modeling and Strain Limits Research Article

Leroy Gardner, Xiang Yun, Andreas Fieber, Lorenzo Macorini

Engineering 2019, Volume 5, Issue 2,   Pages 243-249 doi: 10.1016/j.eng.2018.11.026

Abstract: Since these elements are unable to explicitly capture the local buckling behavior of steel cross-sectionsspecifications use the concept of cross-section classification to determine the extent to which the strengthand deformation capacity of a cross-section are affected by local buckling.However, this article demonstrates that local buckling can be mimicked effectively in beam elements byincorporating the continuous strength method (CSM) strain limits into the analysis.

Efficacy and safety of JAK inhibitor INC424 in patients with primary and post-polycythemia vera or post-essential

Xin Du,Daobin Zhou

Frontiers of Medicine 2016, Volume 10, Issue 4,   Pages 437-443 doi: 10.1007/s11684-016-0472-9

Abstract:

A phase II study (A2202) was performed to evaluate the efficacy and safety of JAK inhibitor ruxolitinib in 63 Chinese MF patients. Ruxolitinib was given twice a day (bid) at a starting dose of 15 mg (n=25) or 20 mg (n=38) based on a baseline platelet count. About 94.7% of the patients achieved a reduction in spleen size, 27.0% of which exhibited significant reduction (≥35%) at week 24. Significant improvement in debilitating constitutional symptoms, as assessed by MFSAF v2.0, was observed in patients treated with ruxolitinib. Ruxolitinib treatment was generally well tolerated by Chinese patients. Although the treatment was associated with an increase in certain adverse events (AEs) that were established as identified risks (anemia and thrombocytopenia), these AEs were considered manageable in this clinical setting. Ruxolitinib provided substantial reductions in splenomegaly and improvements in symptoms, and was well-tolerated by Chinese patients with MF.
