Sorghum phenolic extracts : their storage stability and antioxidant activity in sunflower oil
… in comparison with tertiary butyl hydroquinone (TBHQ), was then evaluated in sunflower oil at concentrations of 1000, 1500 and 2000 ppm in the absence or presence of ferric ions at 2.2 and 4.4 ppm in the dark at 65oC.Progression of oxidation was monitored by measurement of peroxide values (PV) …

Determination of tocopherol isomers and fatty acids in cottonseed oil and oil blends during accelerated storage
… commercially available cottonseed oil containing TBHQ. The oil samples were stored at 65°C for a total of 120 days. The α and γ-tocopherol concentration of each sample were determined using a Waters, model 717 HPLC. The results showed that the initial α-tocopherol concentrations range from 450 ppm …

Design and development of novel tools for the screening and identification of inhibitors of HER receptor family and NFR2 for ovarian cancer therapy
… activation of NRF2 by tert-butyl hydroquinone (tBHQ) upregulates the expression of HER family receptors, HER1 and HER4, elevates phospho protein kinase B (pAKT) levels, and enhances the proliferation of ovarian cancer cells. Pharmacological inhibition using retinoic acid (RA) and bexarotene and …

Potential anti-oxidant benefits of rosemary extract on fry life response of cottonseed oil
… oil, cottonseed oil with synthetic antioxidant (TBHQ), and cottonseed oil with natural antioxidant (rosemary extract) was heated to a temperature of 370°F and 30 batches of potato chips were fried per day. Each experiment was conducted in triplicate. Three 60ml sample of oils were collected at …

Influence of lipid antioxidants on soybean seed storage life
… toluene (BHT), and tert-butylhydroquinone (TBHQ). Germination, seed leakage, seedling vigor, and phospholipids in the embryonic axis were monitored following storage at 40 C for up to 90 days.

Dual regulation of transcription factor Nrf2 by Keap1 and the beta-TrCP/GSK-3 in cancer
… pathway. The ability of tert-butylhydroquinone (tBHQ), 1-[2-cyano-3,12-dioxooleana-1,9(11)-diene-28-oyl]imidazole (CDDO-Im), diethyl maleate (DEM), curcumin, carnosol, ferulic acid and sulforaphane (SFN) to activate Nrf2-target genes in a Keap1-dependent or Keap1-independent manner was tested. It …

DIFFERENTIATION-INDUCED CHANGES IN ANTIOXIDANT CAPACITY AND ANTIOXIDANT RESPONSE IN SH-SY5Y CELLS: ROLE OF NRF2
… cells by Nrf2 using tert-Butylhydroquinone (tBHQ). The levels of GSH, Mn-SOD, HO and OGG1 which are all induced by Nrf2 were determined. The results of the experiment showed that differentiated (post-mitotic) and undifferentiated (mitotic) cells responded similarly to Nrf2 induction as was …

Fate of Omega-3 Fatty Acids from Algae in Mozzarella Cheese
… algal oil and mozzarella cheese. In algal oil, TBHQ (synthetic antioxidant) at 0.0175g/g algal oil prevented DHA degradation for at least 6 weeks, and mixed tocopherols (natural antioxidant) at 400ppm prevented DHA degradation and oxidation for about 4 weeks. DHA degradation in algal oil was …
