In this work, zinc oxide nanoparticles (ZnONPs) and sawdust/epoxy composite (20:80) were mixed using a simple molding method with different ZnONPs concentrations of (0.1, 0.3, 0.5, 0.7, 1.0 %). The samples the nanocomposites characterized by Scanning Electron Microscopy (SEM) technique to demonstrate homogeneity prepared ZnONPs/nanocomposites. photocatalytic activity was examined methylene blue...

The Hoechst dye fluorescence technique, which is used for the quantitative determination of DNA (12), requires high saline concentrations at neutral pH to reach maximal fluorescence of the DNA-dye complex and to render the DNA fully accessible to the dye by dissociating foreign molecules (3,12). In conventional assays, the DNA is alcohol-precipitated and then resuspended in buffer containing 2 ...

OBJECTIVE To observe the contrast spreading patterns in the retrodiscal (RD) approach for transforaminal epidural steroid injections and their effect on pain reduction. METHOD Patients with L5 radiculopathy who were scheduled to receive lumbar TF-EPB were consecutively included. We randomly divided them into the L4-5 RD and L5-S1 RD groups and administered 1 cc of contrast dye into epidural s...
