The nuclear factor erythroid 2-related factor 2 (Nrf2)-mediated antioxidant signaling pathway is a key target for cancer chemoprevention. Recent studies have that Nrf2 activation may be the result of an increase in Nrf2 protein stability. Mangiferin (MA), a compound monomer extracted from the mango plant, has antioxidant and cytoprotective activities. Our previous study demonstrated that MA inc...

A method utilizing thin-layer chromatography with a flame ionization detector (TLC-FID) was developed for assessing the stability of breeder's oil seed samples based on the formation of polar compounds. The results showed a linear relationship between peroxide value (PV) and the content of polar material in the oxidized oil. Oil samples oxidized very readily on chromarods, even at low temperatu...

The aim of this study was to investigate the effect of eugenol treatment and modifi ed atmospheres (50 % N 2 + 50 % CO 2 ) packaging (MAP) on the storage stability of chicken noodles stored at 35 ± 2°C for 90 days. A total four treatments were assigned (i) control aerobic (C-AP), (ii) eugenol treated aerobic (ET-AP), (iii) control MAP (C-MAP), and (iv) eugenol and MAP treated (ET-MAP). All samp...

Ascorbic acid (1), a natural antioxidant, was modified by employing transglycosylation activity of Bacillus stearothermophilus maltogenic amylase with maltotriose and acarbose as donor molecules to enhance its oxidative stability. The transglycosylation reaction with maltotriose as donor created mono- and di-glycosyl transfer products with an alpha-(1,6)-glycosidic linkage. In addition, two aca...

in this project, some new polyaspartimides, (pas)s, have been synthesized form michael addition reaction between new synthetic bismaleimide (bmi) and some aromatic diamines. a characteristic property of this polyaspartimides is a pendent carboxylic group, which introduced to these polymers from new bismaleimide. bismaleimides (bmi) is one of the interesting compounds, which can be self-polymeri...

this study investigated the fatty acids profile, oxidative stability indices, and bioactive compounds of virgin and processed olive oils (leccino and frantoio cultivars). results showed that fatty acid profile of the studied oils contained mostly oleic acid followed by palmitic and linoleic acid. acid values of virgin frantoio and processed leccino were 0.78 and 0.18 mg koh/g oil, with peroxide...
