7 ± 41.9, endocardial 130.2 ± 29.2); 70% baseline-flow (epicardial 160.4 ± 27.7, endocardial 112.1 ± 15.1); 30% baseline-flow (epicardial 44.3 ± 5.5, endocardial 32.9 ± 9); 20 minutes reperfusion (epicardial 175.8 ± 33.6, endocardial 126.5 ± 30); 120 minutes reperfusion (epicardial 146.3 ± 31.1, endocardial 107.1 ± 29.7); and complete LAD occlusion

(epicardial 10.5 ± 5.8 endocardial 1.4 ± 0.3) (r = 0.986–0.962, p < 0.001). Conclusions:  This new blood pressure waveform-triggered laser Doppler probe is able to measure RMBF at different depths online in the beating heart. "
“G-CSF and EPO have shown a notable capability in neovascularization. However, their use is limited because of untoward leucocytosis, erythrogenesis, selleckchem and short half-life in the plasma. Herein, we examined whether G-CSF and EPO released from fibrin gel injected into ischemic tissues would synergistically promote neovascularization with limited systematic effects in a rat hindlimb

ischemic model. In vivo study, group GSK-3 signaling pathway Gel received an intramuscular injection of fibrin gel; group Gel+G-CSF received fibrin gel containing human G-CSF; group Gel+EPO received fibrin gel containing human EPO; group Gel+G-CSF&EPO received fibrin gel containing G-CSF and EPO; group G-CSF&EPO received G-CSF and EPO. Through promoting the expression of SDF-1, local high concentration of EPO could traffic

CXCR4+ cells mobilized by G-CSF CYTH4 to enhance neovascularization in ischemic muscle. The treatment with Gel+G-CSF&EPO was superior to the other treatments on blood flow reperfusion, capillary density, and α smooth muscle actin-positive vessel density. And this treatment induced a modest WBC count increase in peripheral blood. G-CSF and EPO released from fibrin gel had a combined effect on postischemia neovascularization. This treatment may be a novel therapeutic modality for ischemic peripheral artery disease. “

Substance P Activates Both Contractile and Inflammatory Pathways in Lymphatics Through the Neurokinin Receptors NK1R and NK3R. Microcirculation18(1), 24–35. Objective:  The aim of this study was to elucidate the molecular signaling mechanisms by which substance P (SP) modulates lymphatic muscle contraction and to determine whether SP stimulates both contractile as well as inflammatory pathways in the lymphatics. Methods:  A rat mesenteric lymphatic muscle cell culture model (RMLMCs) and known specific pharmacological inhibitors were utilized to delineate SP-mediated signaling pathways in lymphatics. Results:  We detected expression of neurokinin receptor 1 (NK1R) and neurokinin receptor 3 (NK3R) in RMLMCs.
