The Changing Landscape of Maintenance Therapy in Newly Diagnosed Multiple Myeloma: A Systematic Review With Network Meta‐Analysis of the European Myeloma Network (EMN)

American Journal of Hematology, EarlyView.
Our meta‐analysis showed significant improvement of PFS with lenalidomide, proteasome inhibitors, and CD38‐based therapies. A significant OS benefit was noted only with lenalidomide in transplant‐eligible (TE) patients, while CD38‐directed therapy showed a trend toward improved OS.

LEO multi-service routing algorithm based on multi-objective decision making

Tongxin xuebao, 2016
In low earth orbit(LEO) satellite networks,in view of the unbalanced link resource,it's difficult to meet differentiated quality of service(QoS) requirements and easily lead to reduce the efficiency of the whole network.A routing algorithm based on multi-

Numerical and Experimental Assessment of Oxygen Distribution in a Perfusion Bioreactor to Mimic the Osteochondral Niche

Biotechnology and Bioengineering, EarlyView.
ABSTRACT Oxygen supply is a critical parameter in 3D cell cultivation using bioreactors. Since bioreactor designs often prioritise practical constraints, understanding the oxygen supply dynamics of the media is crucial for achieving either uniform or spatially controlled oxygen delivery.
