Today, the economic consumption of biodegradable polymers is of capital importance in many applications. One of the most commonly used biopolymers is polylactic acid (PLA). The printability of the biodegradable film has not been fully investigated. This work tested the printability of polylactic acid (PLA) films and compared the print qualities to common packaging films like low density pol...

The antioxidant activities of TBHQ, BHT and tocopherol mixtures at different concentrations (0, 100, 200, 400 mg/kg) have been evaluated by the application of Differential Scanning Calorimetry (DSC) and Rancimat apparatus. Rancimat apparatus that measures the secondary oxidation products was set at 110 ⁰C with an air flow of 18-20 L/h to measure the induction period (IP) of the samples. The DSC...

TCDD (2,3,7,8-tetrachlorodibenzo- p -dixoin) induces phase II drug-metabolizing enzyme NQO1 [NAD(P)H:quinone oxidoreductase; EC 1.6.99.2; DT-diaphorase] in a wide range of mammalian tissues and cells. Here, we analysed the molecular pathway mediating NQO1 induction by TCDD in mouse hepatoma cells. Inhibition of protein synthesis with CHX (cycloheximide) completely blocks induction of NQO1 by TC...

Rapeseed oil is an important source of edible in the human diet and also highly susceptible to oxidative deterioration. It has been demonstrated that rosemary extract (RE) can increase stability oils. In this work, antioxidant capacity rapeseed after addition RE during storage optimum were investigated. Oxidative evaluation results demonstrate shelf life with incorporation 100 mg/kg was equival...

Nanocomposite composed of organoclay(Cloisite 20A-C20A) and Poly lactic acid (PLA) was prepared by solvent casting method. Physical, mechanical, thermal, barrier and microstructure properties of the composite were studied. X-Ray diffraction (XRD) patterns and scannin...

Plasticized polylactide (PLA) with increased crystallization ability and prolonged life-span in practical applications due to the minimal plasticizer migration was prepared. Branched plasticized PLA was successfully obtained by coupling poly(butylene succinate-co-adipate) (PBSA) to crotonic acid (CA) functionalized PLA. The plasticization behavior of PBSA coupled PLA (PLA-CA-PBSA) and its count...

Isothiocyanates and phenolic antioxidants can prevent cancer through activation of Nrf2 (NF-E2 p45-related factor 2), a transcription factor that controls expression of cytoprotective genes through the antioxidant response element (ARE) enhancer. Using a human mammary MCF7-derived AREc32 reporter cell line, we now report that all-trans retinoic acid (ATRA), and other retinoic acid receptor alph...
