Table 2.

Elemental concentrations (mg/g protein) in lysates prepared from homogenisation of medial temporal cortical tissue from cognitively normal (CN) and Alzheimer’s disease (AD) subjects. Data are presented as mean ± standard deviation (sample size). Significance was set at *p ≤ 0.05, and t-value and degrees of freedom (df) shown. Elemental concentrations differing significantly differently between CN and AD are in bold.
