Article Abstract
Aim: This study evaluated the activity of xanthine oxidase in Nigerians with type 2 diabetic mellitus as well as its relationship with lipid peroxidation, inflammatory bio markers and glycemic control indices.
Methods: Two hundred and thirty seven (237) subjects, comprising of one hundred and fifty seven (157) DM subjects and eighty (80) aged matched controls participated in this study. Blood samples were collected from the participants for the estimations of xanthine oxidase activity, uric acid, malon diadehyde (MDA), erythrocyte sedimentation rate (ESR), high sensitive c - reactive protein (hs CRP), glucose, fructosamine and glycosylated hemoglobin by standard methods.
Results: The results of this study showed a significantly increased activity of xanthine oxidase in DM (0.044 ± 0.05μ/mg) compared with apparently healthy controls (0.028 ± 0.00 μ/mg). The mean plasma levels of MDA (42.40 ± 2.50μmol/l) and uric acid (7.22 ± 0.20 mg/dl) in DM were significantly higher (p ≤ 0.05) than healthy non DM group. The mean levels of hs CRP in DM (4.09 ± 0.91μg/ml) was significantly higher than controls (1.30 ± 0.50μg/ml, p = 0.009). While no association of xanthine oxidase was observed with glycemic control indices and hs CRP, a negative association of xanthine oxidase was observed with MDA (r = -0.514, p = 0.000).
Conclusion: Increased activity of xanthine oxidase in DM was associated with increased lipid peroxidation and could be a salient entity towards the onset on complications.

Ganoderma resinaceum is a traditional mushroom that contains natural products, including ergothioneine (EGT), which has powerful antioxidant properties in the human body. To increase EGT yield from G. resinaceum, the optimal carbon and nitrogen sources in the culture medium were determined as 20 g/L sucrose and 4 g/L NH4Cl, respectively.

In this study, the antioxidant and prooxidant potency of protocatechuic aldehyde (PCA) was evaluated using density functional theory (DFT). The potency of direct scavenging of hydroperoxyl (HOO) and lipid peroxyl radicals (modeled by vinyl peroxyl, HC=CHOO) involved in lipid peroxidation was estimated. The repair of oxidative damage in biomolecules (lipids, proteins and nucleic acids) and the prooxidant ability of PCA phenoxyl radicals were considered.

Polyphenolic plant compounds possess nutritional and pro-healthy potential, reducing the risk of auto-inflammatory and neoplastic diseases. However, their interference with the progression of thyroid gland dysfunctions has remained largely unaddressed. For this purpose, we combined the analyses of phenolic content and antioxidative activity with the thyroid peroxidase (TPO), lipoxygenase (LOX), xanthine oxidase (XO) and cyclooxygenase-2 (COX-2) activity assays, isobolographic approach and the estimation of thyroid cancer cells' proliferation and motility in vitro.

In this study, five seagrass species Halodule uninervis, Thalassia hemprichii, Enhalus acoroides, Cymodocea serrulata, and Syringodium isoetifolium collected from the Mandapam coastal region of Rameswaram (Palk Bay region), Tamil Nadu, India, were selected to identify the antioxidant-rich proteins/peptides. The primary objective was to identify the proteins/peptides present in these seagrass filtrates extracted by using four different pH-based buffer extracts and to assess their antioxidant activity. Among the various buffer extracts, 0.
