The bioactivity and ion release of titanium-containing glass polyalkenoate cements for medical applications

Wren, A.W.; Cummins, Niamh M.; Laffir, Fathima R.; Hudson, Sarah P.; Towler, M.R. (Springer-Verlag, 2011)

The ion release profiles and bioactivity of a series of Ti containing glass polyalkenoate cements (GPCs). Characterization revealed each material to be amorphous with a Tg in the region of 650-660ºC. The network connectivity ...
Comparison of antibacterial properties of commercial bone cements and fillers with a zinc based glass polyalkenoate cement

Wren, A.W.; Cummins, Niamh M.; Towler, M.R. (Springer-Verlag, 2010)

Postoperative infection following invasive surgical procedures is a significant cause for concern, particularly in spinal reconstructive surgery. The objective of the study was to compare the antibacterial efficacy of a ...
The effect of adding organic polymers on the handling properties, strengths and bioactivity of a Ca-Sr-Zn-Si glass polyalkenoate cement

Wren, A.W.; Cummins, Niamh M.; Coughlan, A.; Towler, M.R. (Springer-Verlag, 2010)

This work demonstrates the addition of a number of naturally occurring proteins/polymers to a Zinc based Glass Polyalkenoate Cements (GPCs). Chitin (Chi.) Collagen (Col.), Cysteine (Cys.) and Keratin (Ker.) were added with ...
Raman spectroscopy of fingernails: a novel tool for evaluation of bone quality?

Cummins, Niamh M.; Day, J.C.C.; Wren, A.W.; Carroll, P.; Murphy, N.; Jakeman, Philip M.; Towler, M.R. (Hindawi Publishing Corporation, 2010)

Raman data from human fingernails has been analysed to determine if a relationship exists between spectral features and bone quality. Previous work demonstrated a relationship between the manually determined intensity of ...
A spectroscopic investigation into the setting and mechanical properties of titanium containing glass polyalkenoate cements

Wren, A.W.; Kidari, A; Cummins, Niamh M.; Towler, M.R. (Springer-Verlag, 2010)

Titanium (Ti) implants are extensively used in a number of biomedical and dental applications. This work introduces Ti into the glass phase of a zinc based Glass Polyalkenoate Cement (GPC) and investigates changes in ...
TEM analysis of apatite surface layers observed on zinc based glass polyalkenoate cements

Towler, M.R.; Wren, A.W.; Clarkin, O.M.; Tanner, David A. (Springer, 2008)

Glass polyalkenoate cements (GPCs) are acid base cements formed by the reaction of an aqueous solution of polyalkenoic acid, usually polyacrylic acid (PAA) with an acid degradable aluminosilicate glass. The result of the ...
