“…Therefore, the resulting ternary zirconium-fluoride complex has higher stability than the monomers containing amino- or amido-diacedic acids previously reported [15, 16]. The potential increase of hydrophilicity (water sorption) of this chelating group has been compensated by removal of the two pendent hydroxyl groups from the backbone structure.…”

A new dimethacrylate chelating monomer containing a BisGMA-like backbone structure and a bis(carboxymethyl)-L-lysine chelating group and its ternary zirconium-fluoride complex (antibacterial fluoride-releasing monomer) have been synthesized. The monomer structures were confirmed by 1H-NMR, 13C-NMR, and ES-MS analysis. Several experimental fluoride-releasing dental composites containing different quantities of the new antibacterial fluoride-releasing monomer were formulated and tested for fluoride release, fluoride recharge, compressive and flexural strengths, water sorption and solubility. These composites displayed high fluoride release and recharge capabilities, as well as good physical and mechanical properties.

We report here on the characterization of a three‐generation Chinese family with aminoglycoside‐induced and nonsyndromic hearing impairment. Ten of 17 matrilineal relatives exhibited bilateral and sensorineural hearing impairment. Of these, nine matrilineal relatives, who had a history of exposure to aminoglycosides, exhibited variable severity and audiometric configuration of hearing loss. The dose and age at the time of drug administration seemed to be correlated with the severity of the hearing loss experienced by affected individuals. Sequence analysis of the complete mitochondrial genome in the pedigree showed the presence of homoplasmic A1555G mutation and 37 variants belonging to haplogroup D4a. Of those variants, the G7444A mutation is of special interest as the mutation at this position results in a read‐through of the stop condon AGA of the COI message, thereby adding three amino acids (Lys–Gln–Lys) to the C‐terminal of the polypeptide. Alternatively, the G7444A mutation is adjacent to the site of 3′ end endonucleolytic processing of L‐strand RNA precursor, spanning tRNASer(UCN) and ND6 mRNA. Thus, the G7444A mutation, similar to the deafness‐associated A7445G mutation, may lead to a defect in the processing of the L‐strand RNA precursor, thus influencing the phenotypic expression of the A1555G mutation. These data also imply that nuclear background plays a role in the aminoglycoside ototoxicity associated with the A1555G mutation in this Chinese pedigree. © 2005 Wiley‐Liss, Inc.

“…In recent years, we and others have been developing new fluoride-releasing dental monomers containing ternary heavy-metal-fluoride chelates (Mitra and Wang, 2002; Xu et al, 2004a,b, 2005, 2006a). The results from the experimental composites made of these novel fluoride-releasing monomers have shown significantly higher fluoride-release and recharge capabilities than commercial fluoride-releasing composites, but their physical and mechanical properties are still lower than those of most commercial dental composites.…”

In recent years, the authors have been developing novel fluoride-releasing dental composites containing ternary zirconium fluoride chelates. The aim of this study was to improve the physical and mechanical properties of these composites by improving the formulation of the monomers and photoinitiators. The hypothesis was that reduction of hydrophilic monomers and improvement of the photoinitiators could reduce water sorption and significantly increase the mechanical properties of the composite. The degree of conversion of the composites containing different compositions of photoinitiators was studied by Fourier transform near-infrared spectroscopy (FT-NIR). Ten experimental composites containing different compositions of ethoxylated bisphenol-A dimethacrylate (EBPADMA), 1,6-hexanediol dimethacrylate (HDDMA), triethylene glycol dimethacrylate (TEGDMA), and 2,2-bis[4-(2-hydroxy-3-methacryloyloxypropoxy)phenyl]-propane (BisGMA) were tested for flexural strength, viscosity, and water sorption. The experimental composite containing 20% synthesized fluoride-releasing monomer, 30% BisGMA, 30% EBPADMA, and 20% HDDMA showed significantly higher fluoride release and recharge, but physical and mechanical properties similar to those of the control composite containing 40% BisGMA, 40% EBPADMA, and 20% HDDMA.
