Activation of the mitogen-activated protein kinases (MAPKs) and nuclear factor kappaB (NF-kappaB) cascades after Toll-like receptor (TLR) stimulation contributes to innate immune responses. Signal regulatory protein (SIRP) alpha, a member of the SIRP family that is abundantly expressed in macrophages, has been implicated in regulating MAPK and NF-kappaB(More)
—Weighted coefficients of image retrieval algorithm based on relevance feedback are determined in advance, which is lack of flexibility. In order to obtain satisfactory retrieval results, this algorithm requires a large amount of feedback calculation and efficiency of the algorithm is low. Aiming at the faults of relevance feedback, the adaptive adjustment(More)
With formate as ligand, two 1-D 3d-4f compounds (linear and zigzag) based on pyramidal {TbCu(4)} unit were obtained. Chair-like [(H(2)O)(2)(ClO(4))(2)](2-) clusters and μ(5)-η(1):η(4) bridging mode of formate were observed in the linear one which also displays slow relaxation of the magnetization.
AIMS Late-outgrowth endothelial cells (OECs) exist in blood and other organs. We aimed to explore whether and how OECs participate in re-endothelialization and prevent vascular neointima formation after injury. METHODS AND RESULTS Rabbit bone marrow OECs were cultured for 4 weeks to increase their numbers. Transfusion of autologous OECs (2 × 10⁶-1 ×(More)
