in current work a comprehensive mechanism based on intermediate radical termination theory is assumed for raft polymerization of styrene over cumyl dithiobenzoate as raft agent. rate constants for addition (ka) and fragmentation reactions (kf) are set to 6×106 and 5×104 respectively, which lead to an equilibrium constant value of k = ka/kf = 1.2 x 102. moment equations method was used to model ...

RESULTS: Flow cytometry demonstrated that genetic loss of scleraxis among mesenchymal cells significantly reduced the presence of macrophages (F4/80+) and neutrophils (Cd11b+Ly6G+) at the injury site within 48 hours after injury. The presence of PDGFRa+ mesenchymal cells was also significantly reduced based on both flow cytometry and histologic analysis. These findings were confirmed with cipro...

  Introduction: Radiation Induced Bystander Effect (RIBE) which cause radiation effects in non-irradiated cells, has challenged the principle according to which radiation traversal through the nucleus of a cell is necessary for producing biological responses. What is the mechanism of this phenomenon? To have a better understanding of this rather ambiguous concept substantial number of original ...
