An adhesive and visualized hydrogel‐based detector is designed to monitor the solar radiation dose required for plant growth by discoloration of methylene blue (MB) under sunshine. The based on hybrid hydrogels prepared from photoinitiated polymerization. combination polypropylene (PP) fabrics acting as a substrate polymerization graphitic carbon nitride (g‐C 3 N 4 ) surface enables smaller thi...
Statement of Problem: Recently, investigators have presented new methods to reduce polymerization shrinkage of composite resin restorations. It is claimed that more powerful light cure systems associated with a change in radiation patterns, lead to improved mechanical properties and reduced microleakage. Purpose: The aim of the present study was to evaluate the effects of two curing systems, kn...
Radiation-induced polymerization of vinylbenzyltrimethylammonium chloride (VBT) in aqueous solution has been investigated by steady-state and pulse radiolysis techniques. The effects of dose, dose rate, monomer concentration, pH, and ambient conditions on steady state polymerization were investigated. The reactions of primary radicals of water radiolysis, such as OH radical, e(-)aq, and H atom,...
CTEP is soliciting for phase 1 combination and phase 2 single-agent clinical trials of E7389, a halichondrin B analogue tubulin polymerization inhibitor. E7389 is being developed by CTEP in collaboration with Eisai Research Institute (Eisai). E7389 is also available for nonclinical studies via the NCI through a cooperative agreement with Eisai. CTEP is specifically interested in experiments tha...
PURPOSE Protection of bone marrow against radiotoxicity during radioimmunotherapy and in some cases external beam radiation therapy such as hemi-body irradiation would permit administration of significantly higher doses to tumors, resulting in increased efficacy and safety of treatment. Melanin, a naturally occurring pigment, possesses radioprotective properties. We hypothesized that melanin, w...
Functions of nuclear polymeric proteins such as lamin A/C and actin in transport of plasmid DNA were studied. The results show that the lamina plays an important role in plasmid DNA's entry into the cell nucleus from the cytoplasm. Selective disruption of lamin A/C led to a halt in plasmid DNA transport through the nuclear envelope. Inside the nucleus, plasmid DNA was frequently localized at si...
This study investigated the feasibility of using an electron beam (EB) process to cure chemically impregnated wood products. Maple wood planks were impregnated with the low-viscosity resins 1,6 hexanediol dimethacrylate (HDDA) and trimethylolpropane trimethacrylate (TMPTA). The addition of nanoparticles into the formulation was also studied. The impregnated wood was then cured by EB irradiation...
