“This study was carried out to investigate whether dietary vitamin E and ferulic acid (FA) can exert possible interactions on preventions of hypercholesterolemia and atherogenic lesion formation in C57BL/65 apolipoprotein E-deficient (apo E(-/-)) mice. Four-week-old male apo E(-/-) mice were randomly divided into three groups and given one of three types of Western diets with various amounts of vitamin E (0.02%, 0%, or 0.2%) for 15 weeks. FA was added to vitamin E-free Western diet and check details vitamin E-rich Western diet at the 0.02% level. The plasma total cholesterol concentration was significantly lowered when
FA was added to the vitamin E-free and vitamin E-rich Western diet as compared to the normal
vitamin E Western diet (0.02% vitamin E), and this was accompanied with a decreased hepatic acyl-coenzyme A: cholesterol acyltransferase activity. The hepatic and erythrocyte thiobarbituric acid-reactive substances levels were significantly lowered when FA was added to the vitamin E-rich Western diet, which was attributable to increased activities of antioxidant enzymes (superoxide dismutase, catalase, and glutathione peroxidase) and paraoxonase. Accordingly, vitamin E and/or FA are beneficial for prevention of hypercholesterolemia and atherogenesis in apo E(-/-) S3I-201 mice. In particular, dietary FA exhibited an anti-atherosclerotic property, and this effect was synergistically enhanced with the vitamin E supplement.”
“The microwave absorption properties of single-wall carbon
nanotubes (SWNCTs) and barium ferrite nanocrystalline (SWCNT/BaFe(12)O(19)) composites with different doping ratios are investigated in the frequency region of 2-18 GHz. The transmission line theory is used to calculate the reflection loss properties, and microwave absorptive mechanism of the SWCNT/BaFe(12)O(19) composites is discussed. The experiment results reveal that the microwave absorption properties of composite are very sensitive to the volume percentage of SWCNTs. Owing GANT61 to the multiple absorptive mechanisms, the microwave absorption properties of composite are evidently improved. When SWCNTs are doped with 6 vol% of the sample volume, the maximum reflection loss of the SWCNT/BaFe(12)O(19) composite with a 3 mm thickness reaches 30.79 dB at 10.5 GHz, and the range of resonance absorption peak below -10 dB is about 6 GHz.

“Using the uniaxial compaction method, ceramic disk type microfiltration membranes were fabricated using mixtures of clays to yield membranes M1, M2, and M3. These were obtained with distinct compositions of raw materials at a sintering temperature of 900 degrees C. Membrane characterization was conducted using thermogravimetric analysis (TGA), particle size distribution (PSD), X-ray diffraction (XRD), and scanning electron microscope analysis (SEM).
