The aim of thisstudy was to conduct a randomized, double-blind and placebo-controlled study to investigate the effects of D-004, a lipid extract of the Roystonea regia fruit that prevents testosterone- and phenylepinephrine- induced prostate hyperplasia in rodents, on plasma oxidative markers in healthy men. We enrolled male volunteers （20-55 years） in good health and without lower urinary tract symptoms. Thirty-four eligible participants were randomized to placebo or D-004 （320 mg） capsules administered daily for 6 weeks. An interim check-up and a final visit were conducted after 3 and 6 weeks of therapy, respectively. Physical examinations were performed at each visit, and laboratory tests were performed at baseline and at treatment completion. Oxidative variables included plasma malondialdehyde （MDA）, total hydroxyperoxides （TOH）, sulphydryl （SH） groups and total antioxidant status （TAS）. We assessed treatment compliance and addressed adverse experiences （AEs） at weeks 3 and 6. At week 6, with D-004, the mean reductions of plasma MDA （26.7%）, TOH （18.8%） and SH groups （31.6%）, and the mean increase of TAS （35.3%） were significantly different from those of placebo （P 〈 0.001 for plasma TAS, P 〈 0.0001 for all other comparisons）. D-004 did not differ from the placebo in safety indicators. There were two withdrawals （both in the D-004 group）, with one due to dyspepsia （the only AE during the trial）. In conclusion, D-004 displayed antioxidant effects on plasma oxidative markers in healthy men, which was consistent with findings from laboratory experimental studies.

mechanical and physical characterization of sodium hydroxide treated Borassus fruit fibers

Journal of Forestry Research 2012年第4期23卷 667-674页

In order to improve the properties by chemical modification and to optimize the alkali concentration, we treated Borassus fruit fine fibers with aqueous sodium hydroxide solutions of different concentra- tions. In each case, the tensile properties of the fibers were determined. The morphology of the untreated and alkali treated fibers was observed using scanning electron microscope. The surface of the fibers became rough on alkali treatment. The tensile properties of the fibers improved on alkali treatment. The fibers attained maximum tensile properties when treated with 15% aqueous sodium hydroxide solution and decreased thereafter. The crystallinity index of the fibers showed a similar trend. The thermal stability of the alkali treated fibers was found to be higher than that of untreated fibers. Further, the char content was maximum for fibers treated with alkali having concentration of 15% and above. The chemical composition indicated that the percentageof a-cellulose was maximum when the fibers were treated with 15% aqueous sodium hydroxide solution and then decreased thereafter thus indicating the beginning of degradation of the fibers at higher concentrations. Thus, the optimum concentration of NaOH was established as 15% for alkali treatment of the Borassus fibers.

Morphological, Physical, mechanical, chemical and Thermal characterization of Sustainable Indian Areca fruit Husk Fibers （Areca catechu L.） as Potential Alternate for Hazardous Synthetic Fibers

引用

Journal of Bionic Engineering 2016年第1期13卷 156-165页

作者： J. S. Binoj R. Edwin Raj V. S. Sreenivasan c. Rexin Thusnavis Department of mechanical Engineering St. Xavier' s Catholic College of Engineering Nagercoil - 629003 India Department of mechanical Engineering VV College of Engineering Tisaiyanvilai - 627657 India Department of chemistry St. Xavier' s Catholic College of Engineering Nagercoil - 629003 lndia

Natural fibers can play a major role in composite industry due to its renewable, biodegradable, and eco-friendly properties. Areca fruit Husk （AFH） is rich in fiber, but is wasted in large quantity from tobacco industries. comprehensive characterization of AFH fiber is done to examine its morphological, physical, mechanical, chemical and thermal properties. High cellulose content of the fiber （57.35 wt%） provides better tensile strength （231.66 MPa） whereas the porous surface morphology （40.8 %） ensures better bonding with the matrix. Moreover, the low density of the fiber （0.78 ***^-3） makes it an attractive alternative for hazardous synthetic fibers. The semi-crystalline nature and large crystalline size of the fiber reduce the water absorption char- acteristics. The thermo gravimetric analysis confirms its stability up to 240℃, which is higher than the polymerization tem- perature. The results confirm the potential of AFH fibers as a reinforcement in bio-reinforced polymer composites for automo- tive and structural applications.

Effets of conventional and optimized water and nitrogenmanagements on spinach (Spinacia oleracea L.) growth and soil mineralN (N_min) residues were compared in an open field experiment in whichwater balance method and N recommendation with the KNS-system wereincluded. It was shown that the conventional water treatment(seasonal irrigated amount: 175 mm) reduced spinach growth comparedto the water balance treatments (seasonal irrigated amount: 80 and 85mm) at he same N supply level due to N loss through leaching causedby excessive water supply.
