Isolated internodes of Chara corallina have been used to study the gating of aquaporins (water channels) in the presence of high concentrations of osmotic solutes of different size (molecular weight). Osmolytes were acetone and three glycol ethers: ethylene glycol monomethyl ether (EGMME), diethylene glycol monomethyl ether (DEGMME), and triethylene glycol monoethyl ether (TEGMEE). The 'osmotic...

The v.inetics and stoichiometry of the oxidation of human and rat oxyhemoglobin (02Hb) by propylene glycol dinitrate CGDN) have been investigated in vitro in both hemolysate and in intact red blood cell preparations. In hemolysate fractions from both these species, the rate constant for oxidation is nearly constant between pH 7-0 and 9-0, but it increases dramatically at lower pH values. The re...

Cytotoxicity of triethylene glycol dimethacrylate (TEGDMA), a co-monomer of dental resinous restorative materials, is firmly established in vitro, but the molecular mechanisms are unknown. Here we examined apoptosis and necrosis induced by TEGDMA in human primary pulp cells. The levels of apoptotic and necrotic cell populations differentially increased after exposure to increasing concentration...

This article presents new composite materials with cross-linked structures based on grafted copolymers of collagen acrylates, which were prepared under photocatalytic conditions using the complex oxide RbTe1.5W0.5O6 and additional modifiers. Cross-linking agents for acrylate fragments used. Triethylene glycol dimethacrylate (TEDMA) was used in small volumes, acrylic acid (AA) an amount similar ...

Methods must be developed to improve both the processability and physical properties of zein-based articles. Typical plasticizing gents that improve processability have a negative impact on physical properties at elevated humidities. Continued efforts must be mployed to discover improved plasticizers. Carboxylic acids having more than one carboxylic acid moiety have been evaluated in ein melt f...

OBJECTIVES The primary purpose of this study was to examine the effects of triethylene glycol dimethacrylate (TEGDMA) on odontoclastic differentiation in the dental pulp tissue. MATERIAL AND METHODS The effects of different TEGDMA dosages on the odontoclastic differentiation capability of dental pulp cells were analyzed in vitro using the following methodologies: i) flow cytometry and tartrat...
