Topic: Brain proteins, microglia and lab models

Results Plasma homocysteine value proved to be lower in 7 of the 30 and higher in 6 of the 30 patients studied than the reference range. No statistically significant correlation between the antioxidant activity and N-acetyl-beta-D-glucosaminidase values could be observed. There was no significant alteration in antioxidant activity level.

Key findings

Why it matters

In 30 patients with Down syndrome, plasma homocysteine was lower than the reference range in 7 and higher in 6, and there was no significant alteration in antioxidant activity level. No statistically significant correlation was found between antioxidant activity and N-acetyl-beta-D-glucosaminidase values.
