Leukocyte recruitment requires leukocyte rolling, activation, firm adhesion, and transmigration. Injection of the proinflammatory cytokine TNF-alpha induces expression of E-selectin, interleukin-8, and other adhesion molecules and chemoattractants on the endothelial surface. TNF-alpha- treated CD18 null mouse cremaster muscle venules show increased leukocyte rolling velocity and reduced leukocy...

a plain strain analysis of frictional rolling contact on an elastic graded coating is presented in this paper. finite element method is applied to gain an understanding of the stresses and contact zone properties caused during rolling contact. the effects of friction, material stiffness ratio and coating thickness on stresses in contact zone and coating/substrate interface are studied. shear mo...

Two mechanisms have been proposed for regulating rolling velocities on selectins. These are (a) the intrinsic kinetics of bond dissociation, and (b) the reactive compliance, i.e., the susceptibility of the bond dissociation reaction to applied force. To determine which of these mechanisms explains the 7.5-11.5-fold faster rolling of leukocytes on L-selectin than on E- and P-selectins, we have c...

In this paper an analysis is done on the main drive of rolling mill which consumes about 60 to 70 % of total energy of the plant. The existing rolling mill in India are using the 3 phase induction motor and flywheel to drive the rolling mill. The electric motor transmits the power to flywheel with the help of V-belt. An attempt has made after analysis of existing mill that by using some soft st...

In inflamed venules, neutrophils rolling on E-selectin induce integrin L 2dependent slow rolling on intercellular adhesion molecule-1 by activating Src family kinases (SFKs), DAP12 and Fc receptor(FcR ), spleen tyrosine kinase (Syk), and p38. E-selectin signaling cooperates with chemokine signaling to recruit neutrophils into tissues. Previous studies identified P-selectin glycoprotein ligand-1...

Pipe inspection is one of the areas that have attracted high research interest for robot applications especially in oil and chemical industry and civil engineering. Robot body rolling while it travels within a pipe has been a problem for accurately collecting inspection data. Under certain circumstances where vision systems have to be employed, robot body rolling may cause vision inspection dat...

P-selectin glycoprotein ligand-1 (PSGL-1) mediates the capture (tethering) of free-flowing leukocytes and subsequent rolling on selectins. PSGL-1 interactions with endothelial selectins activate Src kinases and spleen tyrosine kinase (Syk), leading to α(L)β(2) integrin-dependent leukocyte slow rolling, which promotes leukocyte recruitment into tissues. In addition, but through a distinct pathwa...

Chatter has been recognized as major restriction for the increase in productivity of cold rolling processes, limiting the rolling speed for thin steel strips. It is shown that chatter has close relation with rolling conditions. So the main aim of this paper is to attain the optimum set points of rolling to achieve maximum rolling speed, preventing chatter to occur. Two combination methods were ...

allergic airway inflammation is characterized by elaboration of cytokines and chemokines leading to recruitment of inflammatory leukocytes, predominantly eosinophils, to the airways. granulocyte macrophage colony stimulating factor (gm-csf) is generated in the lungs of human subjects with asthma in response to allergen challenge and is necessary for the development of allergen-induced bronchial...

The quality of DNA-labeled affinity probes is critical in DNA-assisted protein analyses, such as proximity ligation and extension assays, immuno-PCR, and immuno-rolling circle amplification reactions. Efficient, high-performance methods are therefore required for isolation of pure conjugates from reactions where DNA strands have been coupled to antibodies or recombinant affinity reagents. Here ...
