Messenger RNA (mRNA) vaccines have emerged as a flexible platform for vaccine development. The evolution of lipid nanoparticles effective delivery vehicles modified mRNA encoding antigens was demonstrated by the response to COVID-19 pandemic. ability rapidly develop SARS-CoV-2 from spike protein genome, and then manufacture multibillions doses per year an extraordinary achievement milestone. Fu...
In this study, a polymer-silica nanocomposite using the sol-gel method was synthesized in three steps at room temperature. The nanocomposite material was formed with an organic compound (polyethylene glycol) and inorganic silica nanoparticles. Furthermore, the size and the distribution of nanoparticles in the polymer matrix were characterized by a transmission electron microscope (TEM). In add...
A mild, efficient and ambient temperature photochemical approach for the synthesis of silver nanoparticle core-shell structures employing a zwitterionic polymer as well as polyethylene glycol is presented.
EBV: Epstein-Barr virus ENKTCL: natural killer/T-cell lymphoma, nasal type NHL: non-Hodgkin’s lymphoma NK: natural killer PEG: polyethylene glycol TIA-1: T-cell intracellular antigen
Polyurethanes and polyurethane-ureas were prepared by the reaction of diethylene glycol and polyethylene glycol with excess of aromatic and aliphatic diisocyanate to yield isocyanate terminated prepolymers which were subsequently reacted with diols and diamines. These polymers were characterized by IR, 1HNMR spectra, viscosity measurements and thermogravimetric analysis.
AIM To study tumor response, and tolerability of arterially directed embolic therapy (ADET) with polyethylene glycol embolics loaded with irinotecan for the treatment of colorectal cancer liver metastases (CRC-LM). Secondary objectives were to monitor quality of life, time to progression and survival of patients. METHODS Patients were included in the study if they were affected by CRC-LM, ref...
BACKGROUND Although polyethylene glycol lavage solutions are widely used for colonoscopy preparation, evidence suggests that sodium phosphate is better tolerated and has similar efficacy. The purpose of this study was to compare compliance with and efficacy of polyethylene glycol and sodium phosphate using meta-analysis and to compare the cost of colonoscopy with both methods. METHODS We used...
The ligand N alpha, B1-(6-biotinylamido)hexanoyl-insulin was attached noncovalently to Sepharose 4B immobilized succinoylavidin to form an insulin-affinity resin. This resin was used to isolate highly purified insulin receptor from human placental tissue by a four step process involving (i) preparation of a crude membrane fraction, (ii) solubilization with Triton X-100, (iii) wheat germ aggluti...
An IgM monoclonal antibody (AGP3) against polyethylene glycol (PEG) was used to assay PEG-modified proteins by ELISA. PEG-modified beta-glucuronidase could be measured at concentrations as low as 15 ng/mL, corresponding to 750 pg (1.8 fmol) of conjugate. This ELISA should be generally applicable to all PEG-modified proteins because AGP3 binds the backbone of the PEG chain independent of the lin...
