Analysis of metabolic compounds and antitumorigenic effects of < em > Albizia niopoides < /em > and < em > Senegalia polyphylla < /em > leaves
The objective of this study was to quantify metabolic compounds in leaves of A. niopoides and S. polyphylla and to evaluate the antitumor potential of extracts from both species in cervical tumour cells. The physiological analyses performed were quantification of starch, sucrose, phenolic compounds and proteins. An aqueous extract was prepared and added to the SiHa cell line at concentrations of 10, 100 and 1000 μg/mL at 4h, 24h, 48h and 72h. Cell morphology, proliferation and viability were analysed. The species showed a large amount of starch and phenolic compounds. Treatment with the extract of both species caused morp...

Fructose-induced hyperuricaemia - protection factor or oxidative stress promoter?
Nat Prod Res. 2024 Mar 24:1-13. doi: 10.1080/14786419.2024.2327624. Online ahead of print.ABSTRACTAccumulating evidence suggests that dietary fructose may play a role in the hyperuricaemia development, but the precise mechanism remains unclear. Hyperuricaemia is characterised by excessive production and deposition of urate crystals, and the metabolism of fructose has been implicated in the elevation of serum urate levels. The association between fructose intake and the risk of hyperuricaemia is explained by the metabolism of fructose in the liver, small intestine, and kidney. Many studies have confirmed the correlation bet...
