Cats about town: Is predation by free-ranging pet cats Felis catus likely to affect urban bird populations? (2008)
Journal Article
Baker, P. J., Molony, S. E., Stone, E., Cuthill, I. C., & Harris, S. (2008). Cats about town: Is predation by free-ranging pet cats Felis catus likely to affect urban bird populations?. Ibis, 150(S1), 86-99. https://doi.org/10.1111/j.1474-919x.2008.00836.x

Even though they are fed daily by their owners, free-ranging pet cats Felis catus may kill wild birds and, given their high densities (typically > 200 cats/km2), it has been postulated that cat predation could be a significant negative factor affecti...

Toothpaste detergents: A potential source of oral soft tissue damage? (2008)
Journal Article
Moore, C., Addy, M., & Moran, J. (2008). Toothpaste detergents: A potential source of oral soft tissue damage?. International Journal of Dental Hygiene, 6(3), 193-198. https://doi.org/10.1111/j.1601-5037.2008.00307.x

OBJECTIVES: Toothpastes are thought to be of benefit to cleaning teeth but may also have the potential for soft tissue damage at least on the cellular level by inclusion of detergents in their formulation. The aim of this study was to observe the in... Read More about Toothpaste detergents: A potential source of oral soft tissue damage?.

On logical gates in precipitating medium: Cellular automaton model (2008)
Journal Article
Martínez, G. J., Adamatzky, A., & de Lacy Costello, B. (2008). On logical gates in precipitating medium: Cellular automaton model. Physics Letters A, 372(31), 5115-5119. https://doi.org/10.1016/j.physleta.2008.05.087

We study a two-dimensional semi-totalistic binary cell-state cellular automaton, which imitates a reversible precipitation in an abstract chemical medium. The systems exhibits a non-trivial growth and nucleation. We demonstrate how basic computationa... Read More about On logical gates in precipitating medium: Cellular automaton model.

New insights into the function of the Wilms tumor suppressor gene WT1 in podocytes (2008)
Journal Article
Morrison, A. A., Viney, R. L., Saleem, M. A., & Ladomery, M. (2008). New insights into the function of the Wilms tumor suppressor gene WT1 in podocytes. AJP - Renal Physiology, 295(1), F12-F17. https://doi.org/10.1152/ajprenal.00597.2007

The Wilms tumor suppressor gene WT1 is essential for early urogenital development: homozygous mutations in WT1 result in embryonic lethality due to a failure in the development of kidneys and gonads. In the adult kidney, WT1 expression is limited to... Read More about New insights into the function of the Wilms tumor suppressor gene WT1 in podocytes.
