Burden of TDP-ir pathology in various brain regions was evaluated working with a semi-quantitative scoring system,Hirsch-Reinshagen et al.

In each case, 1 slide from every in the offered tissue blocks representing distinctive levels of cervical or lumbar spinal cord enlargement was evaluated and the counts averaged (mean number per tissue section). Equivalent evaluation was performed on sections of medulla; having said that, this information was not integrated within the statistical analysis because the variation within the anatomical level resulted in important variations in the representation of the hypoglossal nucleus among cases.Statistical analysis#, catalogue number; GST glutathione S-transferaseStatistical evaluation and data graphing were performed making use of GraphPad Prism six.0 application.
