Improving the anti-demineralizing/remineralizing and mechanical properties of amorphous calcium phosphate (ACP) composites has been the focus of our recent research. In this study, an ethoxylated bisphenol A dimethacrylate (EBPADMA) was blended with triethylene glycol dimethacrylate (TEGDMA), 2-hydroxyethyl methacrylate (HEMA) and methacryloxyethyl phthalate (MEP) to form experimental resins wi...

Alkyl gallates are anticipated for their use as anti-bacterial and anti-viral agents. Although their pharmacological activities depend on their alkyl chain length, no mechanism has yet been clarified. As described herein, we investigated the membrane binding properties of a series of alkyl gallates using fluorescence measurement to elucidate their different pharmacological activities. Membrane ...

This study investigates the influence of triacrylate monomer structure on volume shrinkage, tensile properties, and viscosity vat polymerization (VP) resins. The amount kept constant as 20%wt. to prevent excessive shrinkage effect. Results indicated that ethoxylated propoxylated structures are beneficial reduce VP However, these flexible chain led a reduction in properties elastic modulus resin...

We have studied the depolarized Rayleigh-Wing light scattering of aqueous solutions of 2-butoxyethanol (C&) as a function of the temperature and concentration. The measured spectra give information on the rotational dynamics of water molecules. Their analysis confirm the amphiphilic character of the ethoxylated alcohol molecules that originates micellar structures. In addition, the water dynami...

background: alkyl hydroperoxide reductase (ahpc) of helicobacter pylori is considered as a diagnostic antigen. there­fore, this antigen can be used to detect h. pylori infection by stool immunoassays such as elisa. the aim of this study was to simplify the ahpc protein purification procedures. methods: for whole cell protein extraction, the bacterial cells were ruptured by octly-β-d glucopyrano...

A unique palladium-catalyzed arylation of alkyl sulfenate anions is introduced that affords aryl alkyl sulfoxides in high yields. Due to the base sensitivity of the starting sulfoxides, sulfenate anion intermediates, and alkyl aryl sulfoxide products, the use of a mild method to generate alkyl sulfenate anions was crucial to the success of this process. Thus, a fluoride triggered elimination st...

5- hydroxyisoquinoline undergoes a smooth reaction with alkyl propiolates in the presence of triphenylphosphine (15 mol%) to produce the corresponding (E)-alkyl 3-(isoquinolin-5-yloxy) acrylate in good yields. When the reaction was performed by 2-methyl 4-hydroxyquinoline and 3-nitro 4-hydroxypyridine, similar aryl vinyl ethers were obtained.
