Electrospraying is an effective and facile technique for the production of micro- or nanoparticles with tailored sizes, shapes, morphologies, microstructures. We synthesized functionalizable poly(styrene-random-glycidyl methacrylate) copolymers used them to fabricate microparticles via electrospray technique. The sizes morphologies electrosprayed particles are controlled by altering process parameters (feed rate applied voltage), composition thermodynamic properties polymer (i.e.,...
We report the use of phenolic functional groups lignosulfonate to impart antioxidant properties and cell binding domains gelatin enhance adhesion for poly(ethylene glycol) (PEG)-based scaffolds. Chemoselective thiol–ene chemistry was utilized form composites with thiolated (TLS) methacrylated fish (fGelMA). Antioxidant TLS were not altered after thiolation levels antioxidation comparable those L-ascorbic acid. PEG-fGelMA-TLS significantly reduced difference in COL1A1, ACTA2, TGFB1, HIF1A...
Abstract Simple, versatile, efficient, and readily scalable chemical routes using epoxy‐containing copolymers to achieve complex polymeric structures exhibiting desired functionalities are demonstrated. As proof of concept, Janus nanofiber mats fabricated. epoxide groups in the copolymer can react with various nucleophiles such as amine, alcohol, thiol, single‐side functionalization a primary amine containing dopamine by floating on an aqueous solution is shown. The other side be further...
Background The fluoroscopic-guided epidural access is occasionally challenging; therefore, the contralateral oblique (CLO) view has emerged as an alternative approach. CLO appears to be optimal for mid-thoracic access; however, evidence on its utility lacking. Therefore, we aimed evaluate clinical usefulness of at 60°±5° compared with lateral (LAT) using access. Methods Patients were randomly allocated undergo under fluoroscopic LAT (LAT group) or (CLO group). primary outcome was first-pass...
Background. In patients with postherpetic neuralgia (PHN), the effectiveness of epidural block and benefits adjuvant hypertonic saline (HS) have not been fully determined. Therefore, we investigated these issues in this study. Methods. At a tertiary medical center’s single pain clinic Seoul, Republic Korea, complaining PHN even after 4 months herpes zoster onset were enrolled randomly assigned to either HS or normal (NS) group. After NS administration according each protocol, outcomes...
Background: The performance of the pulse oximeter was evaluated based on ISO 80601-2-61:2011 (E) guidelines. This study aimed to determine whether various finger probes MP570T (MEK-ICS Co., Ltd., Korea) would provide clinically reliable peripheral oxygen saturation (SpO2) readings over a range 70100% arterial (SaO2) during non-motion conditions.Methods: Each volunteer (n = 12) connected breathing circuit for administration hypoxic gas mixture. For frequent blood sampling, an cannula placed...
Background: Inaccuracies associated with target-controlled infusion (TCI) delivery systems are attributable to both software and hardware issues, as well pharmacokinetic variability. However, little is known about the inaccuracy of syringe pump operating in TCI mode. This study aimed evaluate accuracy based on international standards. Methods: A test apparatus for evaluation a (PION TCI®, Bionet Co. Ltd.) was designed apply gravimetric method. Pump evaluated terms deviation defined by...
