In contrast, there was no correlation between TLR-induced cytokine responses and serum levels of core antigen. Thus, hyporesponsiveness to TLR ligands in HCV-infected patients is correlated with liver dysfunction. In conclusion, both host factors and viral factors may be involved in the generation of hyporesponsiveness to TLR ligands in patients with chronic HCV infection.”
“Objective. The objective of this study was to investigate the feasibility of distraction osteogenesis with a nitinol shape memory alloy spring controlled by infrared light.
Study design. In each of 20 New
Zealand VX-770 chemical structure white rabbits, a critical-size defect (15 x 10 mm) was made in the body of the mandible, and a 10 x 8-mm segmental osteotomy was performed just anterior to the defect to create a transporting disk. A heat-controlled distractor and a temperature detector were then inserted (experimental group). Nothing was attached to the other side of the mandible (control group). After a 2-day latency period, the distractor was activated by the infrared at a rate of once per day for 9 days. The contralateral side was treated with the same infrared light. Gross, radiographic, and histologic analyses and dual energy x-ray absorptiometry were performed at regular intervals.
Results.
ALK inhibitor In the experimental group, the mandibular defect was reconstructed, whereas in the control group it was not. The histologic appearance of regenerated bone was similar to that observed with traditional
distraction osteogenesis.
Conclusion. Distraction osteogenesis using a nitinol spring controlled by infrared light is possible. (Oral Surg Oral Med Oral Pathol Oral Radiol Endod 2010; 110: 157-166)”
“We report an investigation of the dc voltage generated in a normal-metal (NM) layer by spin pumping from an adjacent ferromagnetic (FM) layer under ferromagnetic resonance (FMR) excitation. The spin-current injected across the FM/NM interface by the spin pumping effect generates a charge current along the NM layer by means of the inverse spin Hall effect. Room temperature field scan measurements were made in a series of Ni(81)Fe(19)/Pt bilayers with several thicknesses of the FM and Pt layers. By varying the angle of the in-plane magnetization we are able to accurately Sotrastaurin mw separate the contributions arising from anisotropic magnetoresistance and from the spin-current pumped into the NM layer by the precessing magnetization of the FM layer. The data for the spin pumping dc voltage is in excellent agreement with a theory incorporating the full dependence on the thicknesses of the FM and NM layers. (C) 2011 American Institute of Physics.
