sagebrush genus (artemisia scoparia) is the one of the most important genus of asteraceae family. it has numerous values because of medicine properties. sagebrush genus has numerous application in traditional medicine from ancient times. in this research, the isolation and identification of essential oil and antibacterial activity of artemisia scoparia have been studied. samples were collected ...

OBJECTIVE To calibrate and correct the gradient errors including gradient amplitude scaling errors, background/imaging gradients, and residual gradients in diffusion tensor imaging (DTI). METHODS A calibration protocol using an isotropic phantom was proposed. Gradient errors were estimated by using linear regression analyses on quadratic functions of diffusion gradients along 3 orthogonal dir...

Background: Intravenous drug delivery is an advantageous choice for rapid administration, immediate drug effect, and avoidance of first-pass metabolism in oral drug delivery. In this study, the synthesis, formulation, and characterization of atorvastatin-loaded polyurethane (PU) nanoparticles were investigated for intravenous route of administration. Method: First, PU was synthesized and charac...

background and objective: reliable methods of detection of antimicrobial resistance are of paramount importance in the treatment and management of infections caused by coagulase negative staphylococci (cons). the objective of the present study was to compare and evaluate the performance of disc diffusion and e test (epsilometer test) methods for antimicrobial testing of coagulase negative staph...
