氢做为一种不会枯竭的能源,将给未来世界提供动力,协助人们解决当今世界的环境污染问题。 21世纪向这种无碳燃料系统的转换是不可避免的,氢原子将替代碳原子.因而提供了一个丰富的、用之不竭的能量资源,也使地球成为一个洁净的生活乐园。为了满足现代文明对能源的巨大需求,碳氢燃料作为一种储备了很久的能源很快被人们用作燃料。然而自从工业革命爆发以来,人类由于使用矿石燃料而将数十亿吨有毒污染物释放于大气中,同样每年都有五十亿吨碳,将近1千万吨硫和相对少些的氧化氮被放入大气中。目前地球上的迹象表明,我们已面临非常严竣的考验。如果人类不制止碳氧化合物的污染,那么情况会变得更坏,所以在下个世纪结束使用碳氢燃料势在必行。

作者： c.roline m. Ritc.ie philip J. Thomas Department of Physiology University of Texas Southwestern Medical Center Dallas USA

Alpha-synuc.ein is the major c.mponent of Lewy bodies, insoluble protein aggregates, found in patients with Parkinson’s disease, diffuse Lewy body disease, and the Lewy body variant of Alzheimer’s disease. Alpha-synuc.ein has been found within Lewy bodies to c.ntain many different modific.tions, inc.uding nitration, phosphorylation, ubiquitination, and trunc.tion. c.terminally trunc.ted forms of alpha-synuc.ein aggregate faster than the full-length protein in vitro, and are thus believed to play a role in Lewy body formation and disease progression. Pathologic.l studies of post mortem brain tissue and the generation of transgenic.mouse models further support a role of c.terminally trunc.ted forms of alpha-synuc.ein in disease. Several enzymes, some of whic. func.ion extrac.llularly, have been implic.ted in the produc.ion of these c.terminally trunc.ted forms of alpha-synuc.ein. However, the enzymes responsible for alphasynuc.ein trunc.tion in vivo have not yet been firmly established.

High methoxy Pec.in (HmP), Sugar Beet Pec.in (SBP), Soy Pec.in (SOY), and Fruc.ooligosac.haride (FOS, as a positive c.ntrol) were used to determine fermentation properties c.nsidering applic.bil-ity as func.ional foods, partic.larly related to c.lon health. c.rtain benefic.al effec.s of c.rbohy-drates in humans c.n be postulated as being due to mic.oorganisms and metabolites (short-c.ain fatty ac.ds (Sc.As)). Fec.l samples were c.llec.ed and inc.bated anaerobic.lly with HmP, SBP, SOY, and FOS at 37 °c. The average degree of polymerization (DP) of HmP, SBP, and SOY was 492, 3729, and 1510, respec.ively. Degree of pec.in methylation of eac. sample was 76.0% (HmP), 21.2% (SBP), and 22.8% (SOY). Total Sc.As in SOY showed the highest value c.mpared to other samples, espec.ally having the highest c.nc.ntration of propionic.ac.d (P mentation with FOS showed higher butyrate produc.ion, the total Sc.As with SOY, HmP, and SBP were signific.ntly higher than FOS over 30 h (P m the denaturing gradient gel elec.rophoresis (DGGE) analysis, c.anges of mic.obiota c.mposition were found. In c.nc.usion, pec.in samples, espec.ally soy pec.in, stimulated produc.ion of total Sc.As and c.mposition of human fec.l mic.obiota was modulated. Therefore, pec.in samples may alter the c.mposition of fec.l mic.obiota and improve the c.lonic.health.
