Kinetic Studies of Lycopene Isomerization in a Tributyrin Model System at Gastric pH

A semi-preparative HPLC method was developed in order to isolate and purify the 13-cis-lycopene isomer in tomato-based materials. The result was compared with the naturally predominant all-trans-lycopene isomer, in terms of stability to gastric pH at physiological temperature in a tributyrin model system. Kinetic experiments confirmed that lycopene isomerization is a reversible reaction, and under these conditions the all-trans isomer is more stable than the 13-cis isomer. In addition, it was found that at gastric pH 13-cis-lycopene would predominantly isomerize to the all-trans form rather than undergo oxidation/breakdown. A simulation based on the rate constants calculated in the kinetic study indicated that at gastric pH the lycopene isomeric distribution aimed toward an equilibrium characterized by approx 16% 13-cis-, 16% 9-cis-, and 68% all-trans-lycopene. This study suggests that pH-driven isomerization in the stomach is at least partially responsible for the relatively high cis-lycopene proportion found in vivo.

Structure and Physical Properties of Zein/Pluronic F127 Composite Films

Triblock copolymer Pluronic F127 has been used to form composites with zein, a corn protein and coproduct of the bioethanol industry, to alleviate its natural brittleness. At low F127 loadings (0–35%), the plasticizing effect was dominant, and the elongation at break of zein composite film containing 35% F127 was about 8-fold higher than that of the zein film with 10% F127. At high F127 loadings (50–100%), a large number of lamellae crystals were formed in the film matrix as verified by a combination of differential scanning calorimetry (DSC), atomic force microscopy (AFM), and small-angle X-ray scattering (SAXS). The F127 crystallization surpassed its plasticizing effect, resulting in an increased brittleness of zein film with the further increase of F127 loading. Compared with the flat-on lamellae of pure F127, F127 chains folded into branch-like lamellar structures in the zein composite film containing 50% F127 due to the confinement of amorphous zein. Besides, the crystals in zein films were composed of extended chain integral folding (IF = 0) and once-folded chain (IF = 1) polyethylene oxide (PEO) crystals, and the portion of once-folded chain (IF = 1) PEO crystals increased with F127 loading. Thus, through investigation of the competition of plasticizing effect and crystal formation under different F127 loadings, the optimized F127 loading in zein/F127 composite film with a good overall performance was determined to be at around 35%

伝送路の状態を考慮したマルチキャリヤ伝送用回線制御方式

マルチキャリヤ信号のサブキャリヤから伝送路の状態を比較的容易に推定できることに着目し、これを利用して伝送品質を向上させるマルチキャリヤ伝送用の回線制御方式を提案する。提案方式では、受信電力が小さく伝送品質が劣化していると予想されるサブキャリヤにはデータを割り当てずにダミーキャリヤとして送信し、受信電力が大きく伝送品質が良好であると予想されるサブキャリヤのみにデータを割り当てて伝送する。移動通信環境を想定した性能評価の結果、すべてのサブキャリヤにデータを割り当てる通常のマルチキャリヤ伝送方式に比べ、受信レベルの低いサブキャリヤをダミーキャリヤとしてデータを割り当てない提案方式のほうが、伝送効率が向上することを示す。更に提案方式における誤り訂正符号の効果を明らかにする。journal articl

Depiction of Time-dependent Calibration Curve for y-Ray Irradiater Using Radiophotoluminescence and ESR Dosimetry

Time-dependent calibration curve for the γ-ray irradiator was prepared using radiophoto -luminescence (RDPL) and ESR dosimetry. In RDPL measurement, the radiation dose was linearly increased until 38 Gy. However, above 38 Gy, it deviated upward. The ESR signal intensity of γ-irradiated L-α-alanine indicated linear in the range from 0 to 500 Gy. Though ESR signal intensity of L-α-alanine was saturated with the microwave power, the linearity of the calibration curve was reserved at any microwave power (< 5 mW). Summarizing these results, the time-dependent calibration curve was obtained using γ-irradiated L-α-alanine in the range of 0 - 500 Gy after correction by RDPL for the radiation dose below 38 Gy.departmental bulletin pape
