Figure Lengend Snippet: U-shaped relationship between dietary lysine and serum uric acid in growing quails, fitted with Truncated Fourier, Morgan-Mercer-Flodin (MMF), and Sinusoidal models.

Article Snippet: Serum uric acid (UA) concentration was determined using a commercial enzymatic uricase–peroxidase colorimetric assay kit (e.g., Randox, Sigma), according to the manufacturer’s instructions.

Article Title: Oral L-glutamine rescues fructose-induced poor fetal outcome by preventing placental triglyceride and uric acid accumulation in Wistar rats

Figure Lengend Snippet: Effects of glutamine (GLN) on placental adenosine deaminase activity (ADA; a), xanthine oxidase activity (XO; b) and uric acid concentration (c) and plasma ADA (d), XO (e) and uric acid concentration (f) in pregnant rats that consumed high fructose drink (FED). FED increased plasma and placental ADA, XO activity and uric acid concentration, which were attenuated by glutamine supplementation. Data were analysed by one-way ANOVA followed by Bonferroni post hoc test. (∗∗∗ p < 0.0001, ∗∗ p < 0.001 and ∗ p < 0.01).

Article Snippet: Standard enzymatic colorimetric methods using reagents obtained from Randox Laboratory Ltd. (Co. Antrim, UK) were used to determine ADA and XO activities from the placental tissue homogenates and plasma, whereas placental and plasma uric acid (UA) concentrations were estimated by non-enzymatic colorimetric method using kits obtained from Randox Laboratory Ltd. (Co. Antrim, UK).
