Does a pterostilbene derivative suppress osteoclastogenesis by regulating RANKL-mediated NFκB and MAPK signaling in RAW264.7 cells?
This study thus identifies PTERC-T as an inhibitor of osteoclast formation and provides evidence for its role in preventing osteoporosis and other bone related disorders. However, further studies are needed to establish its efficacy in vivo.
Although patients with prior upper-body venous obstruction may have lower systemic oxygen saturations at hospital discharge, they do not demonstrate an increased SCPC failure or mortality rate. Innominate vein occlusion or its equivalent in patients with bilateral SVCs should not preclude the performance of SCPC. Physiologic rather than anatomic evaluation of preoperative systemic venous return may be more useful to predict outcome after SCPC.
